Assaf RD, Hamad R, Javanbakht M, Arah OA, Shoptaw SJ, Cooper ZD, Gorbach PM. Associations of U.S. state-level COVID-19 policies intensity with cannabis sharing behaviors in 2020. Harm Reduct J. 2024 Apr 16;21(1):82. doi: 10.1186/s12954-024-00987-y. PMID: 38622670.

Abstract

Background: Cannabis use before the COVID-19 pandemic for many involved sharing prepared cannabis for inhalation, practices that were less prevalent during the pandemic. State-level COVID-19 containment policies may have influenced this decrease. This study examined the extent to which the intensity of state-level COVID-19 policies were associated with individual-level cannabis sharing. Findings have the potential to guide harm reduction policies for future respiratory pandemics and seasonal respiratory virus waves.

Methods: This study used cross-sectional individual-level data from the COVID-19 Cannabis Study, an anonymous U.S.-based web survey on cannabis use disseminated during the early phase of the pandemic (Full sample N = 1,883). We combined individual-level data with state-level policy data from Kaiser Family Foundation’s State COVID-19 Data and Policy Actions for three time-points from June to August 2020 that overlapped with the survey period. Cannabis sharing was dichotomized as any versus no sharing. We adapted a previously published coding framework to score the intensity of COVID-19 policies implemented in each U.S. state and averaged the policy score across the time period. We then used Poisson regression models to quantify the associations of the average state-level COVID-19 policy score with cannabis sharing during the pandemic.

Results: Participants (n = 925) reporting using inhalation as a mode for cannabis use were included in this analysis. Most respondents were male (64.1%), non-Hispanic White (54.3%), with a mean age of 33.7 years (SD 8.8). A large proportion (74.9%) reported sharing cannabis during the pandemic. Those who shared cannabis more commonly lived in states with a lower average policy score (16.7, IQR 12.3-21.5) compared to those who did not share (18.6, IQR 15.3-25.3). In adjusted models, the prevalence ratio of any cannabis sharing per every 5-unit increase in the average COVID-19 policy score was 0.97 (95% CI 0.93, 1.01).

Conclusions: Fewer individuals shared cannabis in states with more intense COVID-19 containment policies compared to those in states with less intense policies. Individuals who use cannabis may be willing to make changes to their behavior and may further benefit from specific and directed public health messaging to avoid sharing during respiratory infection outbreaks.

Abstract

Background

There has been a significant increase in methamphetamine use and methamphetamine use disorder (Meth UD) in the United States, with evolving racial and ethnic differences.

Objectives

This secondary analysis explored racial and ethnic differences in baseline sociodemographic and clinical characteristics as well as treatment effects on a measure of substance use recovery, depression symptoms, and methamphetamine craving among participants in a pharmacotherapy trial for Meth UD.

Methods

The ADAPT-2 trial (ClinicalTrials.gov number, NCT03078075; N=403; 69% male) was a multisite, 12-week randomized, double-blind, trial that employed a two-stage sequential parallel design to evaluate the efficacy of combination naltrexone (NTX) and oral bupropion (BUP) vs. placebo for Meth UD. Treatment effect was calculated as the weighted mean change in outcomes in the NTX-BUP minus placebo group across the two stages of treatment.

Results

Of the 403 participants in the ADAPT-2 trial, the majority (65%) reported non-Hispanic White, while 14%, 11% and 10% reported Hispanic, non-Hispanic Black, and non-Hispanic other racial and ethnic categories respectively. At baseline non-Hispanic Black participants reported less severe indicators of methamphetamine use than non-Hispanic White. Treatment effects for recovery, depression symptoms and methamphetamine cravings did not significantly differ by race and ethnicity.

Conclusions

Although we found racial and ethnic differences at baseline, our findings did not show racial and ethnic differences in treatment effects of NTX-BUP on recovery, depression symptoms and methamphetamine cravings. However, our findings also highlight the need to expand representation of racial and ethnic minority groups in future trials.

Freese J, Segura ER, Gutierrez J, Lake JE, Cabello R, Clark JL, Blair C. Sexual network characteristics and partnership types among men who have sex with men diagnosed with syphilis, gonorrhoea and/or chlamydia in Lima, Peru. Sex Transm Infect. 2024 Feb 19;100(2):84-90. doi: 10.1136/sextrans-2023-055910. PMID: 38124224; PMCID: PMC10922481.

Abstract

Objectives: Sexual networks are known to structure sexually transmitted infection (STI) transmission among men who have sex with men (MSM). We sought to estimate the risks of STI diagnosis for various partnership types within these networks.

Methods: Our cross-sectional survey analysed data from 1376 MSM screened for a partner management intervention in Lima, Peru. Participants were tested for HIV, syphilis, gonorrhoea (NG) and chlamydia (CT) and completed surveys on their demographics, sexual identity/role, HIV status, partnership types and sexual network from the prior 90 days. χ2 and Wilcoxon rank-sum tests compared participants without an STI to those diagnosed with (1) syphilis, (2) NG and/or CT (NG/CT) and (3) syphilis and NG/CT coinfection (coinfection).

Results: 40.8% (n=561/1376) of participants were diagnosed with an STI (syphilis: 14.9%, NG/CT: 16.4%, coinfection: 9.5%). 47.9% of all participants were living with HIV and 8.9% were newly diagnosed. A greater proportion of participants with syphilis and coinfection were living with HIV (73.5%, p<0.001; 71.0%, p<0.001) compared with those with NG/CT (47.8%) or no STI (37.8%). Participants with syphilis more often reported sex-on-premises venues (SOPVs) as the location of their last sexual encounter (51.7%, p=0.038) while those with NG/CT tended to meet their last sexual partner online (72.8%, p=0.031). Respondents with coinfection were the only STI group more likely to report transactional sex than participants without an STI (31.3%, p=0.039).

Conclusions: Sexual networks and partnership types of Peruvian MSM are associated with differential risks for STIs. Participants diagnosed with syphilis tended to meet single-encounter casual partners at SOPV, while MSM with NG/CT were younger and often contacted casual partners online. Coinfection had higher frequency of transactional sex. These findings suggest the potential importance of public health interventions through combined syphilis/HIV screening at SOPV, syphilis screening at routine clinic appointments for MSM living with HIV and directed advertisements and/or access to NG/CT testing through online platforms.

Participant experiences in a pilot study for methamphetamine withdrawal treatment: Implications for retention. Int J Drug Policy. 2024 Mar 12;126:104383. doi: 10.1016/j.drugpo.2024.104383. Epub ahead of print. PMID: 38479162.

Abstract

Introduction: There is little knowledge of the perspectives of people who use methamphetamine and have participated in clinical trials, and none for interventions not intended to address abstinence. A better understanding of these experiences could lead to more patient centred clinical trial design. This study seeks to understand the experiences of people who completed a clinical trial of lisdexamfetamine for the treatment of acute methamphetamine withdrawal.

Methods: Thematic analysis of open-ended, semi-structured interviews with eight people who participated in an inpatient clinical trial of lisdexamfetamine for acute methamphetamine withdrawal. Interviews were conducted between days 3 and 6 of admission to an inner-city Sydney hospital.

Results: Participants described how research procedures, the research setting, and the investigational product affected their experiences while enrolled in a clinical trial. Of particular importance to participants were transparent and low burden trial procedures, a welcoming trial environment, trusting relationships and effective communication, which were linked with the participants’ subsequent decision to remain enrolled in the trial.

Discussion: The experiences of participants in this clinical trial can be distilled into four meta-themes: agency, caring-trust, safety, and communication. Participants spontaneously linked these experiences with a capacity to remain enrolled in the study. By considering the experiences of trial participants in clinical trial design, researchers can improve the experiences of future trial participants and facilitate their choice to remain enrolled in clinical trials.

Measuring Objective and Subjective Sleep during Lisdexamfetamine Treatment of Acute Methamphetamine Withdrawal: A Feasibility Study. Eur Addict Res. 2024 Mar 18:1-5. doi: 10.1159/000536328. Epub ahead of print. PMID: 38498995.

Abstract

Introduction: Sleep disturbance is common during methamphetamine (MA) use and withdrawal; however, the feasibility of combined subjective-objective measurement of sleep-wake has not been shown in this population. Actigraphy is a well-established, non-invasive measure of sleep-wake cycles with good concordance with polysomnography. This study aimed to investigate the feasibility and utility of using actigraphy and sleep diaries to investigate sleep during MA withdrawal.

Methods: We conducted a feasibility and utility study of actigraphy and sleep diaries during a clinical trial of lisdexamfetamine for MA withdrawal. Participants were inpatients for 7 days, wore an actigraph (Philips Actiwatch 2) and completed a modified Consensus Sleep Diary each morning. Participants were interviewed between days 3-5.

Results: Ten participants (mean age 37 years, 90% male) were enrolled. No participant removed the device prematurely. Participants interviewed (n = 8) reported that the actigraph was not difficult or distracting to wear or completion of daily sleep diary onerous. Actigraphic average daily sleep duration over 7 days was 568 min, sleep onset latency 22.4 min, wake after sleep onset (WASO) 75.2 min, and sleep efficiency 83.6%. Sleep diaries underreported daily sleep compared with actigraphy (sleep duration was 56 min (p = 0.008) and WASO 47 min (p &lt; 0.001) less). Overall sleep quality was 4.4 on a nine-point Likert scale within the diary.

Conclusions: Continuous actigraphy is feasible to measure sleep-wake in people withdrawing from MA, with low participant burden. We found important differences in self-reported and actigraphic sleep, which need to be explored in more detail.

Decreasing Stigma Toward People Who Inject Drugs: Harm Reduction Training for First-Year Medical Students. Acad Med. 2024 Feb 27. doi: 10.1097/ACM.0000000000005675. Epub ahead of print. PMID: 38412474.

Abstract

Problem: Stigma in health care toward people who inject drugs (PWID) is a well described, significant barrier to quality care, resulting in poor health outcomes. Harm reduction offers a person-centered counter-framework for minimizing harm for people who use drugs. Despite the evidence in support of harm reduction, medical students typically receive minimal training on harm reduction and the care of PWID.

Approach: To fill this gap, medical students at University of California, Los Angeles organized around the principles of harm reduction to improve the medical school curriculum related to PWID. Students screened lectures for stigmatizing language and collaborated with faculty to improve lecture materials. They partnered with a community organizer and hosted a mandatory 1-hour lecture and 30-minute discussion introducing the principles of harm reduction within an overdose prevention, recognition, and response training for first-year medical students during medical school orientation in August 2022. An anonymous online pre- and posttest survey, assessing student attitudes toward PWID, was used to evaluate the effects of the training.

Outcomes: A total of 156 students completed the pretest survey, and 107 students completed the pre- and posttest survey (68.5% response rate). The overall posttest mean stigma score was 1.8 (standard deviation [SD] = 0.5) and was significantly lower than the pretest mean of 2.1 (SD = 0.7; P < .0001), indicating a reduction in stigma among medical student attitudes after the course. There was statistically significant improvement in attitudes for 7 of 13 component measures.

Next steps: This analysis demonstrated that the mandatory class has the capacity to improve medical student attitudes toward PWID. The authors plan to further evaluate the program’s effectiveness through measuring and reporting outcomes for future student cohorts. The authors are working with curriculum directors to further incorporate harm reduction principles into other lectures and problem-based learning exercises.

Brief Report: Substance Use Care Continuum in Women With and Without HIV in the Southern United States. J Acquir Immune Defic Syndr. 2024 Apr 15;95(5):424-430. doi: 10.1097/QAI.0000000000003373. Epub 2024 Mar 11. PMID: 38133580; PMCID: PMC10927302.

Abstract

Background:

Substance use (SU) contributes to poor outcomes among persons living with HIV. Women living with HIV (WWH) in the United States are disproportionately affected in the South, and examining SU patterns, treatment, and HIV outcomes in this population is integral to addressing HIV and SU disparities.

Methods:

WWH and comparable women without HIV (WWOH) who enrolled 2013–2015 in the Women’s Interagency HIV Study Southern sites (Atlanta, Birmingham/Jackson, Chapel Hill, and Miami) and reported SU (self-reported nonmedical use of drugs) in the past year were included. SU and treatment were described annually from enrollment to the end of follow-up. HIV outcomes were compared by SU treatment engagement.

Results:

At enrollment, among 840 women (608 WWH, 232 WWOH), 18% (n = 155) reported SU in the past year (16% WWH, 24% WWOH); 25% (n = 38) of whom reported SU treatment. Over time, 30%, 21%, and 18% reported SU treatment at 1, 2, and 3 years, respectively, which did not significantly differ by HIV status. Retention in HIV care did not differ by SU treatment. Viral suppression was significantly higher in women who reported SU treatment only at enrollment (P = 0.03).

Conclusions:

We identified a substantial gap in SU treatment engagement, with only a quarter reporting treatment utilization, which persisted over time. SU treatment engagement was associated with viral suppression at enrollment but not at other time points or with retention in HIV care. These findings can identify gaps and guide future strategies for integrating HIV and SU care for WWH.

BMC Public Health. 2024 Feb 15;24(1):481. doi: 10.1186/s12889-024-17871-w. PMID: 38360616; PMCID: PMC10870618.

Abstract

Intimate partner violence (IPV) occurs at alarmingly high rates towards pregnant women in South Africa. Experiences of emotional, physical, and sexual IPV in pregnancy can adversely impact the health and safety of mother and fetus. Furthermore, IPV is associated with increased risk of HIV, exacerbating the public health impact of violence among pregnant women in this HIV endemic setting. In-depth understanding of cultural and contextual drivers of experiences of IPV is a critical precursor to development of interventions effectively addressing this issue among pregnant women in South Africa. The present study examines factors contributing to IPV among pregnant women to identify potential points of intervention. We conducted twenty in-depth interviews with postpartum women who used oral pre-exposure prophylaxis (PrEP) in pregnancy and reported recent experiences of IPV and/or ongoing alcohol use in a township near Cape Town, South Africa that experiences a heavy burden of both HIV and IPV. Interpretive thematic analysis was used. Several patterns of IPV during pregnancy were identified and violence was frequently described as co-occurring with male partner alcohol use. A majority of women referenced oral PrEP as their preferred method for HIV prevention, highlighting the agency and discretion it provided as beneficial attributes for women experiencing IPV. Fear of judgement from peers for remaining with an abusive partner and a lack of clear community messaging around IPV were identified as barriers to disclosure and support-seeking. Addressing the lack of social support received by women experiencing IPV during pregnancy in South Africa is essential to comprehensive IPV programming.

Abstract

Background

Persons with opioid use disorders who inject drugs (PWID) in the United States (US) face multiple and intertwining health risks. These include interference with consistent access, linkage, and retention to health care including medication for opioid use disorder (MOUD), HIV prevention using pre-exposure prophylaxis (PrEP), and testing and treatment for sexually transmitted infections (STIs). Most services, when available, including those that address substance misuse, HIV prevention, and STIs, are often provided in multiple locations that may be difficult to access, which further challenges sustained health for PWID. HPTN 094 (INTEGRA) is a study designed to test the efficacy of an integrated, “whole-person” strategy that provides integrated HIV prevention including antiretroviral therapy (ART), PrEP, MOUD, and STI testing and treatment from a mobile health delivery unit (“mobile unit”) with peer navigation compared to peer navigation alone to access these services at brick and mortar locations.

Methods

HPTN 094 (INTEGRA) is a two-arm, randomized controlled trial in 5 US cities where approximately 400 PWID without HIV are assigned either to an experimental condition that delivers 26 weeks of “one-stop” integrated health services combined with peer navigation and delivered in a mobile unit or to an active control condition using peer navigation only for 26 weeks to the same set of services delivered in community settings. The primary outcomes include being alive and retained in MOUD and PrEP at 26 weeks post-randomization. Secondary outcomes measure the durability of intervention effects at 52 weeks following randomization.

Discussion

This trial responds to a need for evidence on using a “whole-person” strategy for delivering integrated HIV prevention and substance use treatment, while testing the use of a mobile unit that meets out-of-treatment PWID wherever they might be and links them to care systems and/or harm reduction services. Findings will be important in guiding policy for engaging PWID in HIV prevention or care, substance use treatment, and STI testing and treatment by addressing the intertwined epidemics of addiction and HIV among those who have many physical and geographic barriers to access care.

J Ethn Subst Abuse. 2024 Feb 7:1-15. doi: 10.1080/15332640.2023.2297392. Epub ahead of print. PMID: 38327151.

Abstract

 

Background: While rates of opioid use disorder (OUD) are lower among women compared to men, nativity may have disproportionate impacts on OUD risk among Hispanic/Latinx women but remain understudied.

Objective: To assess the association between country of birth and reported OUD risk among low-income Hispanic/Latinx women in primary care in Los Angeles, CA.

Methods: This was a cross-sectional study of 1189 non-pregnant, Hispanic/Latinx women attending two federally qualified health centers in Los Angeles between March and July 2013. OUD risk was assessed using the Alcohol, Smoking, and Substance Involvement Screening Test (ASSIST), and moderate-to-high risk was defined as ASSIST score ≥ 4.

Results: Overall, 4.2% of women (n = 49) were at moderate-to-high risk for OUD. Risk for OUD was higher among US-born women compared to foreign-born women (6.7 vs. 1.7%; p < .01), those who reported 2+ chronic medical conditions (p < .01), and those who were at moderate-to-high risk for other substance use disorders (p < .01). In multivariable logistic regression analyses, being U.S.-born was independently associated with being at moderate-to-high risk for OUD among Hispanic/Latinx women as compared to those who were foreign-born (AOR = 2.8; 95% CI 1.2-6.8).

Conclusion: Among low-income Hispanic/Latinx women presenting to primary care, one in twenty patients is at-risk for OUD. The odds of moderate-high risk of OUD were three times as high in US-born compared to foreign-born women, and higher among those with chronic medical conditions and those at risk of other substance use disorders. Gender-specific and culturally-tailored screening for OUD may inform overdose prevention interventions for US-born Hispanic/Latinx women.

Cannabis Use and Biomarkers of Inflammation, Immune Activation, and Microbial Translocation in Persons with HIV. Cannabis Cannabinoid Res. 2024 Feb 9. doi: 10.1089/can.2023.0109. Epub ahead of print. PMID: 38335314.

Abstract

Background: The relationship between cannabis and inflammation among persons with HIV (PWH) remains unclear. We examined whether the cannabis metabolite 11-nor-9-carboxy THC (THC-COOH) is associated with lower levels of plasma biomarkers of inflammation, immune activation, and microbial translocation in PWH. We hypothesized that cannabis use would be associated with lower levels of plasma inflammatory biomarkers than noncannabis use. Methods: We quantified THC-COOH in plasma, with THC-COOH levels between 5.1-69.9 μg/L and ≥70 μg/L being classified as moderate and heavy cannabis use, respectively, with noncannabis use defined as undetected THC-COOH. We measured a panel of plasma biomarkers of inflammation (interleukin [IL]-1-β, tumor necrosis factor-alpha, IL-18, IL-6, and C-reactive protein), immune activation (CD14 and CD163), and microbial translocation (iFABP2 and lipopolysaccharide binding protein [LBP]), with all biomarkers collected on the same day. We used a cross-sectional design and linear regression models to test whether cannabis use is associated with lower biomarker levels. Results: Participants were (N=107) sexual minority men with HIV (median age=32 years, IQR=28, 38), of whom 65% were virally suppressed; 36%, 44%, and 20% were classified as nonuse, moderate, and heavy cannabis, respectively. In linear regression models adjusted for viral suppression, stimulant use, and CD4 counts, heavy cannabis use was significantly associated with lower levels of log10 LBP (β=-0.14, 95% confidence interval: -0.24 to -0.04; false discovery rate=0.0029; partial eta squared=0.07) than noncannabis users. No precise associations were observed for other biomarkers (all p>0.05). Conclusions: Our findings suggest that cannabis use may be associated with lower plasma LBP. Further work is needed to clarify the relationship between cannabis use and biomarkers of microbial translocation in PWH.

JAMA Netw Open. 2024 Jan 2;7(1):e2353771. doi: 10.1001/jamanetworkopen.2023.53771. PMID: 38285444; PMCID: PMC10825722.

Abstract

Importance

Although substantial evidence supports buprenorphine for treatment of opioid use disorder (OUD) in controlled trials, prospective study of patient outcomes in clinical implementation of emergency department (ED) buprenorphine treatment is lacking.

Objective

To examine the association between buprenorphine treatment in the ED and follow-up engagement in OUD treatment 1 month later.

Design, Setting, and Participants

This multisite cohort study was conducted in 7 California EDs participating in a statewide implementation project to improve access to buprenorphine treatment. The study population included ED patients aged at least 18 years identified with OUD between April 1, 2021, and June 30, 2022. Data analysis was performed in October 2023.

Exposure

All participants were offered buprenorphine treatment for OUD (either in ED administration, prescription, or both), the uptake of which was examined as the exposure of interest.

Main Outcomes and Measures

The primary outcome was engagement in OUD treatment 30 days after the ED visit, determined by patient report or clinical documentation. The association of ED buprenorphine treatment with subsequent OUD treatment engagement was estimated using hierarchical generalized linear models.

Results

This analysis included 464 ED patients with OUD. Their median age was 36.0 (IQR, 29.0-38.7) years, and most were men (343 [73.9%]). With regard to race and ethnicity, 64 patients (13.8%) self-identified as non-Hispanic Black, 183 (39.4%) as Hispanic, and 185 as non-Hispanic White (39.9%). Most patients (396 [85.3%]) had Medicaid insurance, and more than half (262 [57.8%]) had unstable housing. Self-reported fentanyl use (242 [52.2%]) and a comorbid mental health condition (328 [71.5%]) were common. Interest in buprenorphine treatment was high: 398 patients (85.8%) received buprenorphine treatment; 269 (58.0%) were administered buprenorphine in the ED and 339 (73.1%) were prescribed buprenorphine. With regard to OUD treatment engagement at 30 days after the ED visit, 198 participants (49.7%) who received ED buprenorphine treatment remained engaged compared with 15 participants (22.7%) who did not receive ED buprenorphine treatment. An association of ED buprenorphine treatment with subsequent OUD treatment engagement at 30 days was observed (adjusted risk ratio, 1.97 [95% CI, 1.27-3.07]).

Conclusions and Relevance

The findings of this cohort study suggest that among patients with OUD presenting to EDs implementing low-threshold access to medications for OUD, buprenorphine treatment was associated with a substantially higher likelihood of follow-up treatment engagement 1 month later. Future research should investigate techniques to optimize both the uptake and effectiveness of buprenorphine initiation in low-threshold settings such as the ED.

Impact of Potential Case Misclassification by Administrative Diagnostic Codes on Outcome Assessment of Observational Study for People Who Inject Drugs. Open Forum Infectious Diseases, 2024;, ofae030, https://doi.org/10.1093/ofid/ofae030

Abstract

Introduction

Initiation of medications for opioid use disorder (MOUD) within the hospital setting may improve outcomes for people who inject drugs (PWID) hospitalized due to an infection. Many studies used International Classification of Diseases (ICD) codes to identify PWID, although these may be misclassified and thus, inaccurate. We hypothesized that bias from misclassification of PWID using ICD codes may impact analyses of MOUD outcomes.

Methods

We analyzed a cohort of 36,868 cases of patients diagnosed with Staphylococcus aureus bacteremia at 124 US Veterans Health Administration (VHA) hospitals between 2003 and 2014. To identify PWID, we implemented an ICD code-based algorithm and a natural language processing (NLP) algorithm for classification of admission notes. We analyzed outcomes of prescribing MOUD as an inpatient using both approaches. Our primary outcome was 365-day all-cause mortality. We fit mixed effects Cox regression models with receipt or not of MOUD during the index hospitalization as the primary predictor and 365-day mortality as the outcome.

Results

NLP identified 2,389 cases as PWID, while ICD codes identified 6,804 cases as PWID. In the cohort identified by NLP, receipt of inpatient MOUD was associated with a protective effect on 365-day survival (AHR 0.48, 95%CI 0.29-0.81, p<0.01) compared to those not receiving MOUD. There was no significant effect of MOUD receipt in the cohort identified by ICD codes (AHR 1.00, 95%CI 0.77-1.30, p=0.99).

Conclusion

MOUD was protective of all-cause mortality when NLP was used to identify PWID, but not significant when ICD codes were used to identify the analytic subjects.

Abstract

This study examined the prevalence and correlates of intimate partner violence (IPV) among a cohort of racial/ethnically diverse men who have sex with men (MSM) in Los Angeles. An ongoing longitudinal cohort study of MSM in Los Angeles, constructed by design so half of the participants use substances (SU) and half are persons living with HIV, provided data. Data collection occured between 2014 and 2020. At semiannual study visits, participants completed a computer-assisted self-interview which included questions on substance use (past 6 months) and experiences of IPV (past 12 months). The criterion variable was reported physical and sexual IPV. Multivariable models generalized estimating equations (GEE) estimated associations between reported SU and physical and sexual IPV, adjusting for repeated measurement and confounders. In total, 557 persons (2,962 visits) contributed to the analysis; the median baseline age was 30 years (interquartile range: 28.0–39.0). The prevalence of IPV in the past 12 months was 22.3%, with 18.3% reporting physical and 10.2% reporting sexual IPV across study visits. Stimulant use prevalence was higher among those who reported IPV compared to those who did not (68% vs. 42.1%; p < .001); cannabis use prevalence was lower among those reporting IPV (42.3% vs. 49% respectively; p < .001). Adjusted analysis showed reported stimulant use associated with greater odds of physical IPV (adjusted odds ratio [aOR] = 2.0; 95% confidence interval [CI] [1.4, 2.8], p < .001) but not sexual IPV (aOR = 1.3; 95% CI [0.8, 2.0], p = .332). Models stratified by HIV status yielded similar results. Findings showed a high prevalence of past-year IPV experiences among MSM in Los Angeles. Findings highlight links between SU and IPV and underscore a significantly increased likelihood of IPV for MSM in Los Angeles who report current methamphetamine use. This study provides evidence to support universal IPV screening and to make available safety resources at all points where MSM seek healthcare.

Abstract

Introduction:Methamphetamine use threatens positive treatment outcomes in substance use and HIV, for people with opioid use disorders (POUD) in many countries. This paper describes the adaptation of four evidence-based interventions (EBI) (motivational interviewing, contingency management, Matrix group model and SMS text messaging) for treating methamphetamine use among POUD receiving methadone maintenance therapy in Vietnam.

Methods: Following the ADAPT-ITT (Assessment-Decision-Administration-Production-Topical experts-Training-Testing) framework, we conducted 16 focus group discussions with POUD (n = 25) and providers (n = 22) at four methadone clinics in two largest cities (Hanoi in the North, Ho Chi Minh City in the South) to assess patterns of methamphetamine use and to get feedback on proposed EBIs. The proposed EBIs were properly adapted and used to train providers in two of the four methadone clinics. The revised EBIs were tested over 12 weeks among 42 POUD on methadone who use methamphetamine. Post-intervention feedback served to fine-tune the revised EBIs.

Results: Insights about patterns of methamphetamine use suggested that EBIs should focus on different triggers to methamphetamine use among POUD receiving methadone treatment in the two cities. All EBIs should emphasise family-related topics to build a strong motivation for treatment. Participants suggested when, where and how each EBI should be delivered. Most participants were satisfied with the adapted EBIs. Limited human resources at methadone clinics might hinder implementation of the adapted EBIs.

Discussion and conclusions: We successfully completed the adaptation of EBIs for POUD who use methamphetamine on methadone in Vietnam. The pilot testing of the adapted EBIs demonstrated feasibility and acceptability.

Romero R, Friedman JR, Goodman-Meza D, Shover CL. US drug overdose mortality rose faster among hispanics than non-hispanics from 2010 to 2021. Drug Alcohol Depend. 2023 May 1;246:109859. doi: 10.1016/j.drugalcdep.2023.109859. Epub 2023 Mar 29. PMID: 37031488.

Abstract

Background: Historically, overdose mortality rates among Hispanics have been lower than non-Hispanics. The purpose of this analysis was to characterize the U.S. overdose crisis among Hispanics compared to non-Hispanics.

Methods: We used the Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiological Research (WONDER) platform to obtain drug overdose mortality rates per 100,000 population between 2010 and 2021 for Hispanics and non-Hispanics. We examined the relative percent change and specific drug involvement (2010-2021) and state-level disparities (2010-2020) among Hispanics versus non-Hispanics. We calculated rate ratios by state and annual percent change in total and for each specific drug. Statistical analyses were performed using R software version 4.0.3 (R Project for Statistical Computing).

Results: Nationally, from 2010 to 2021, Hispanic overdose rates rose from 5.6 to 21.7 per 100,000, an increase of 287.5 % compared to 13.5-35.1 per 100,000, an increase of 160 % among non-Hispanics. The average annual percent change was 12 % for Hispanics and 9 % for non-Hispanics. The three most common drug classes involved in overdose deaths among both groups included: Fentanyls and synthetic opioids; cocaine; and prescription opioids. Hispanic overdose rates were higher than non-Hispanic rates in New Mexico, Colorado, Massachusetts, and Pennsylvania in 2020, versus only Michigan in 2010.

Conclusions: We observed disparities in overdose mortality growth among Hispanics compared to non-Hispanics from 2010 to 2021. These disparities highlight the urgency to develop community-centered solutions that take into consideration the social and structural inequalities that exacerbate the effects of the opioid overdose crisis on Hispanic communities.

The Impact of COVID-19 on HIV Care in Rio de Janeiro, Brazil 2019-2021: Disparities by Age and Gender. AIDS Behav. 2023 Jan 30:1–13. Epub ahead of print. PMID: 36715887; PMCID: PMC9885404.

Abstract: 

We evaluated COVID-19’s impact on HIV care indicators among INI/FIOCRUZ’s HIV Clinical Cohort in Rio de Janeiro, Brazil: (1) Adequate care visits: two visits ≥ 90 days apart; (2) Adequate viral load monitoring: ≥ 2 viral load results ≥ 90 days apart; (3) Consistent viral suppression: all viral loads < 40 copies/mL; and (4) ART medication possession ratio (MPR) ≥ 95%. Chi-square tests compared the fraction of participants meeting each indicator per period: pre-pandemic (3/1/2019–2/29/2020) and post-pandemic (3/1/2020–2/28/2021). Logistic regression models were used to assess disparities in adequate care visits. Among 906 participants, care visits and viral load monitoring decreased pre-pandemic to post-pandemic: 77.0–55.1% and 36.6–11.6% (both p < 0.001), respectively. The optimal MPR rate improved from 25.5 to 40.0% (p < 0.001). Post-pandemic period (aOR 0.33, CI 0.28–0.40), transgender women (aOR 0.34, CI 0.22–0.53), and those aged 18–24 years (aOR 0.67, CI 0.45–0.97) had lower odds of adequate care visits. COVID-19 disrupted care access disproportionately for transgender women and younger participants.

Syndemic trajectories of heavy drinking, smoking, and depressive symptoms are associated with mortality in women living with HIV in the United States from 1994 to 2017. Drug Alcohol Depend. 2023 Aug 1;249:110838. Epub 2023 Jun 19. PMID: 37352734.

Abstract

Background: Heavy drinking, smoking, and depression are common among people with HIV. Little is known about the co-occurring, synergistic effect of having two or more of these conditions long-term –a sustained syndemic – on mortality among women with HIV (WWH).

Methods: Data from 3282 WWH of the Women’s Interagency HIV Study from 1994 to 2017 were utilized. National Death Index review identified cause of death (n=616). Sustained syndemic phenotypes were based on membership in high-risk groups defined by group-based trajectory models of repeated self-reported alcohol use, smoking, and depressive symptoms and their co-occurrence. Cox proportional hazard models estimated associations of sustained syndemic phenotypes with all-cause, non-AIDS, and non-overdose mortality, adjusting for age, race/ethnicity, education, enrollment wave, illicit drug use, and time-varying HIV viral load and CD4+ T-cell count.

Results: WWH were 58% Black and 26% Hispanic, with a mean baseline age of 36.7 years. Syndemic phenotypes included zero (45%, n=1463), heavy drinking only (1%, n=35), smoking only (28%, n=928), depressive symptoms only (9%, n=282), and 2+ trajectories (17%, n=574). Compared to zero trajectories, having 2+ trajectories was associated with 3.93 times greater all-cause mortality risk (95% CI 3.07, 5.04) after controlling for confounders and each high-risk trajectory alone. These findings persisted in sensitivity analyses, removing AIDS- and overdose-related mortalities.

Conclusions: Clustering of 2+ conditions of heavy drinking, smoking, and depression affected nearly one in five WWH and was associated with higher mortality than zero or one condition. Our findings underscore the need for coordinated screening and parsimonious treatment strategies for these co-occurring conditions.

Substance use and other factors associated with COVID-19 vaccine uptake among people at risk for or living with HIV: Findings from the C3PNO Consortium. Prev Med Rep. 2023 Jun 24:102300. doi: 10.1016/j.pmedr.2023.102300. Epub ahead of print. PMCID: PMC10289823.

Abstract: 

Objective: We describe the prevalence of COVID-19 vaccine uptake, substance use, and other factors associated with vaccine hesitancy among participants from nine North American cohort studies following a diverse group of individuals at risk for or living with HIV.

Methods: Between May 2021 and January 2022, participants completed a survey related to COVID-19 vaccination. Participants included those with and without substance use. Those responding as ‘no’ or ‘undecided’ to the question “Do you plan on getting the COVID-19 vaccine?” were categorized as vaccine hesitant. Differences between groups were evaluated using chi-square methods and multivariable log-binomial models were used to calculate prevalence ratios (PR) of COVID-19 vaccine hesitancy with separate models for each substance.

Results: Among 1,696 participants, COVID-19 vaccination was deferred or declined by 16%. Vaccine hesitant participants were younger, with a greater proportion unstably housed (14.8% vs. 10.0%; p = 0.02), and not living with HIV (48.% vs. 36.6%; p <.01). Vaccine hesitant participants were also more likely to report cannabis (50.0% vs. 42.4%; p = 0.03), methamphetamine (14.0% vs. 8.2%; p <.01), or fentanyl use (5.5% vs. 2.8%; p = 0.03). Based on multivariable analyses methamphetamine or fentanyl use remained associated with COVID-19 vaccine hesitancy (Adjusted PR = 1.4; 95% CI 1.1–1.9 and Adjusted PR = 1.6; 95% CI 1.0–2.6, respectively).

Conclusion: As new COVID-19 vaccines and booster schedules become necessary, people who use drugs (PWUD) may remain vaccine hesitant. Strategies to engage hesitant populations such as PWUD will need to be tailored to include special types of outreach such as integration with substance use programs such as safe injection sites or recovery programs.

Social Networks Play a Complex Role in HIV Prevention Knowledge, Attitudes, Practices, and the Uptake of PrEP Through Transgender Women Communities Centered Around Three “Casas Trans” in Lima, Peru: A Qualitative Study. J Int Assoc Provid AIDS Care. 2023 Jan-Dec;22:23259582231196705. PMID: 37753609; PMCID: PMC10524076.

Abstract

Transgender women’s (TW) social networks may facilitate HIV prevention information dissemination and normative reinforcement. We conducted a qualitative study of social networks among 20 TW affiliated with 3 “casas trans” (houses shared among TW) in Lima, Peru, using diffusion of innovations theory to investigate community-level HIV prevention norms. Participants completed demographic questionnaires, social network interviews, and semistructured in-depth interviews. Median age was 26 and all participants engaged in sex work. Interviews revealed high HIV prevention knowledge and positive attitudes, but low engagement in HIV prevention. Respondents primarily discussed HIV prevention with other TW. Network members’ opinions about pre-exposure prophylaxis (PrEP) frequently influenced respondents’ personal beliefs, including mistrust of healthcare personnel, concern that PrEP efficacy was unproven, fear of adverse effects, and frustration regarding difficulty accessing PrEP. Patterns of influence in TW networks may be leveraged to improve uptake of HIV prevention tools, including PrEP.

Kidd JD, Smiley SL, Coffin PO, Carmody TJ, Levin FR, Nunes EV, Shoptaw SJ, Trivedi MH. Sexual orientation differences among men in a randomized clinical trial of extended-release naltrexone and bupropion for methamphetamine use disorder. Drug Alcohol Depend. 2023 Jul 17;250:110899. Epub ahead of print. PMID: 37478502.

Abstract:

Background

Methamphetamine use disorder (MethUD) disproportionately affects men who have sex exclusively with men or with men and women (collectively MSM/W), compared to men who have sex with women (MSW). This study is the first MethUD medication trial to compare treatment effect for these groups, hypothesizing that extended-release injectable naltrexone 380 mg every 3 weeks plus oral extended-release bupropion 450 mg daily would be less effective for MSM/W than MSW.

Methods

Data come from men (N = 246) in a multi-site, double-blind, randomized, placebo-controlled trial with sequential parallel comparison design. In Stage 1 (6-weeks), participants were randomized to active treatment or placebo. In Stage 2 (6-weeks), Stage 1 placebo non-responders were rerandomized. Treatment response was ≥3 methamphetamine-negative urine samples, out of four obtained at the end of Stages 1 and 2. Treatment effect was the active-versus-placebo between-group difference in the weighted average Stages 1 and 2 responses.

Results

MSM/W (n = 151) were more likely than MSW (n = 95) to be Hispanic, college-educated, and living with HIV. Adjusting for demographics, among MSM/W, response rates were 13.95 % (active treatment) and 2.78 % (placebo) in Stage 1; 23.26 % (active treatment) and 4.26 % (placebo) in Stage 2. Among MSW, response rates were 7.69 % (active treatment) and 5.80 % (placebo) in Stage 1; 3.57 % (active treatment) and 0 % (placebo) in Stage 2. Treatment effect was significantly larger for MSM/W (h = 0.1479) than MSW (h = 0.0227) (p = 0.04).

Conclusions

Findings suggest efficacy of extended-release naltrexone plus bupropion for MSM/W, a population heavily burdened by MethUD. While a secondary outcome, this intriguing finding merits testing in prospective trials.

Reproductive health syndemics impact retention in care among women living with HIV in Rio de Janeiro, Brazil. The Brazilian journal of infectious diseases : an official publication of the Brazilian Society of Infectious Diseases27(4).

Abstract: 

Syndemic psychosocial and reproductive factors affecting women’s retention in HIV care remain understudied. We analyzed correlates of non-retention in a cohort of women with HIV in Brazil from 2000‒2015. Participants self-reported exposure to physical/sexual violence, illicit drug use, adolescent pregnancy, or induced abortion. Lifetime history of these psychosocial stressors were used to create a syndemic score based on the presence or absence of these conditions. All dichotomous variables were summed (range 0 to 4), with greater scores indicating more syndemic factors experienced. Logistic regression models identified predictors of non-retention, defined as < 2 HIV viral load or CD4 results within the first year of enrollment. Of 915 women, non-retention was observed for 18%. Prevalence of syndemic factors was adolescent pregnancy (53.2%), physical/sexual violence (38.3%), induced abortion (27.3%), and illicit drug use (17.2%); 41.2% experienced ≥ 2 syndemic conditions. Syndemic scores of 2 and 3 were associated with non-retention, as well as low education, years with HIV and seroprevalent syphilis. Psychosocial and reproductive syndemics can limit women’s retention in HIV care. Syphilis infection predicted non-retention and could be explored as a syndemic factor in future studies.

PMID: 37070545; PMCID: PMC10330081

Abstract

Objective: To longitudinally evaluate differences in HIV viral suppression (<200 copies/ml) by intersections of race/ethnicity, gender, and psychosocial issues in people with HIV in the Los Angeles County Medical Care Coordination Program.

Design: We analyzed 74 649 viral load measurements over 10 184 people with HIV enrolled in the Medical Care Coordination Program between January 1, 2013 and March 1, 2020.Methods: We fit Bayesian logistic hierarchical random effects models to test interactions between gender, race/ethnicity, and a psychosocial acuity score on viral suppression over time from 1 year prior to program enrollment to 24 months after enrollment.

Results: The probability of viral suppression declined prior to enrollment, then increased and stabilized by 6 months after enrollment. Black/African American patients with low and moderate psychosocial acuity scores did not achieve the same increase in percentage of viral suppression as those in other racial/ethnic groups. Transgender women with high psychosocial acuity scores took longer (about 1 year) to achieve the same percentage of viral suppression as clients of other gender identities.

Conclusions: Some racial/ethnic and gender disparities in viral suppression persisted after enrollment in the Los Angeles County Medical Care Coordination Program while accounting for psychosocial acuity score, which may be explained by factors not assessed in the program.

Assaf RD, Javanbakht M, Gorbach PM, Arah OA, Shoptaw SJ, Cooper ZD. Puff, Puff, Don’t Pass: harm reduction for cannabis use during a viral respiratory pandemic. Harm Reduct J. 2023 Feb 25;20(1):23. PMID: 36829150; PMCID: PMC9957690.

Abstract:

Background: Prior to the COVID-19 pandemic, cannabis use social practices often involved sharing prepared cannabis (joints/blunts/cigarettes) and cannabis-related paraphernalia. Previous studies have demonstrated that sharing paraphernalia for cannabis, tobacco, and crack cocaine is a risk factor for respiratory viral and bacterial infections. Although COVID-19 is a respiratory viral infection that spreads through droplets and airborne transmission, it is unclear if many individuals adopted harm reduction practices around sharing cannabis. This study: quantifies the prevalence of sharing prepared non-medical cannabis and cannabis-related paraphernalia reported before and during the pandemic; assesses changes in sharing of non-medical cannabis from before to during the pandemic; assess the association between frequency of non-medical cannabis use and sharing of cannabis during the pandemic; and describes how respondents obtained their cannabis and the reasons for changing their cannabis use during the pandemic to explain differences in sharing patterns.

Methods: This cross-sectional study used data collected from an anonymous, US-based web survey on cannabis-related behaviors from August to September 2020 (n = 1833). Participants were included if they reported using a mode of inhalation for non-medical cannabis consumption. We calculated proportional changes in sharing cannabis before/during the COVID-19 pandemic. Associations between frequency of cannabis use and cannabis sharing during the COVID-19 pandemic were assessed using logistic regression analysis.

Results: Overall, 1,112 participants reported non-medical cannabis use; 925 (83.2%) reported a mode of cannabis inhalation. More respondents reported no sharing during (24.9%) than before the pandemic (12.4%; p < 0.01); less respondents shared most of the time (19.5% before; 11.2% during; p < 0.01) and always during the pandemic (5.2% before; 3.1% during; p < 0.01). After adjusting for covariates, the odds of any sharing during the pandemic for those who reported ≥ weekly cannabis use was 0.53 (95% CI 0.38, 0.75) compared to those who reported ≤ monthly.

Conclusions: Sharing of prepared cannabis and cannabis-related paraphernalia decreased during the COVID-19 pandemic compared to before the pandemic. This finding suggests potential risk mitigation strategies taken by participants for COVID-19 prevention either directly through behavior change or indirectly through adherence to COVID-19 prevention recommendations. Harm reduction messaging around sharing of cannabis during surges of COVID-19 or other respiratory infections may provide benefit in reducing infection among those who use cannabis, especially as cannabis use in the USA continues to increase.

Psychometrics of the Concise Health Risk Tracking Self-Report (CHRT-SR16) Assessment of Suicidality in a Sample of Adults with Moderate to Severe Methamphetamine Use Disorder: Findings from the ADAPT-2 Randomized Trial. Neuropsychiatr Dis Treat. 2023 Jun 22;19:1443–54. doi: 10.2147/NDT.S406909. PMCID: PMC10292610.

Abstract:

Background

The co-occurrence of suicidality and substance use disorders has been well established, but rating scales to examine suicidal behavior and risk are sparse among participants with substance use disorders. We examined the psychometric properties of the 16-item Concise Health Risk Tracking Scale – Self Report (CHRT-SR16) to measure suicidality among adults with moderate-to-severe methamphetamine use disorder.

Methods

Participants (n = 403) with moderate-to-severe methamphetamine use disorder completed the CHRT-SR16 as part of a randomized, double-blind, placebo-controlled pharmacotherapy trial. The CHRT-SR16 factor structure was assessed using confirmatory factor analysis (CFA). Internal consistency was estimated with coefficients alpha (α) and omega (ω), test-retest reliability with intraclass correlation coefficient (ICC) and standard error of measurement, and convergent validity using Spearman’s ρ rank order correlation coefficient test between CHRT-SR16 factors and the Patient Health Questionnaire (PHQ-9). The analyses utilized baseline and week 1 data (for test-retest reliability only).

Results

CFA revealed a seven-factor model of Pessimism, Helplessness, Social Support, Despair, Impulsivity, Irritability, and Suicidal Thoughts as the best-fitting model. The CHRT-SR16 also exhibited strong internal consistency (α = 0.89; ω = 0.89), test-retest reliability (ICC = 0.78) and convergent validity with the PHQ-9 total score (ρ = 0.62).

Conclusion

The CHRT-SR16 showed strong psychometric properties in a sample of participants with primary methamphetamine use disorder.

Murphy L, Bowra A, Adams E, Cabello R, Clark JL, Konda K, Perez-Brumer A. PrEP policy implementation gaps and opportunities in Latin America and the Caribbean: a scoping review. Ther Adv Infect Dis. 2023 Apr 17;10:20499361231164030. PMID: 37114192; PMCID: PMC10126665.

Abstract:

Background: Pre-exposure prophylaxis (PrEP) is an important tool for HIV prevention in Latin America and the Caribbean (LAC). Yet, little is known about the PrEP policies landscape in the region. Addressing this gap, this scoping review assessed current PrEP policies throughout LAC to better understand existing PrEP implementation gaps and identify opportunities to improve access.

Methods: We conducted a scoping review, using a modified PRISMA extension, through 28 July 2022, to identify country-level PrEP policies. Data were collected in English, Spanish, French, and Portuguese utilizing online platforms for screening and data extraction (Google Forms, Zotero, and Excel). Extracted data were divided by data source, including country-level government policies, gray literature, and peer-reviewed literature, with at least one full-text reviewer and data extractor per publication. An iterative summative content analysis was performed to compare and interpret themes across phases and data sources.

Results: Of the 33 countries in LAC, 22 (67%) had policies approving daily oral PrEP for HIV prevention, which outlined specific key populations, including men who have sex with men, transgender women, sex workers, and serodiscordant couples. Generic tenofovir disoproxil fumarate/emtricitabine has been approved in 15 of the 33 countries, and 13 of the 33 countries have incorporated PrEP into their public health system. No countries were found to have approved cabotegravir. Costing data were reported by only one country, Ecuador, in its national health ministry guidelines. Findings also document a lag between the media/gray-literature announcement of PrEP and implementation of policies.

Conclusion: Findings underscore significant advances in PrEP policies in the region and signal opportunities for greater PrEP implementation. Since 2017, an increasing number of countries have begun to provide PrEP to communities at heightened need, although significant gaps remain. Policy approval is a key step to further increasing access to PrEP in LAC, necessary to reduce the burden of HIV in LAC, specifically among marginalized populations.

Reid SC, Wang V, Assaf RD, Kaloper S, Murray AT, Shoptaw S, Gorbach P, Cassels S. Novel Location-Based Survey Using Cognitive Interviews to Assess Geographic Networks and Hotspots of Sex and Drug Use: Implementation and Validation Study. JMIR Form Res. 2023 Jun 22;7:e45188. doi: 10.2196/45188. PMID: 37347520; PMCID: PMC10337421..

Abstract:

Background

The Ending the HIV Epidemic initiative in the United States relies on HIV hotspots to identify where to geographically target new resources, expertise, and technology. However, interventions targeted at places with high HIV transmission and infection risk, not just places with high HIV incidence, may be more effective at reducing HIV incidence and achieving health equity.

Objective

We described the implementation and validation of a web-based activity space survey on HIV risk behaviors. The survey was intended to collect geographic information that will be used to map risk behavior hotspots as well as the geography of sexual networks in Los Angeles County.

Methods

The survey design team developed a series of geospatial questions that follow a 3-level structure that becomes more geographically precise as participants move through the levels. The survey was validated through 9 cognitive interviews and iteratively updated based on participant feedback until the saturation of topics and technical issues was reached.

Results

In total, 4 themes were identified through the cognitive interviews: functionality of geospatial questions, representation and accessibility, privacy, and length and understanding of the survey. The ease of use for the geospatial questions was critical as many participants were not familiar with mapping software. The inclusion of well-known places, landmarks, and road networks was critical for ease of use. The addition of a Google Maps interface, which was familiar to many participants, aided in collecting accurate and precise location information. The geospatial questions increased the length of the survey and warranted the inclusion of features to simplify it and speed it up. Using nicknames to refer to previously entered geographic locations limited the number of geospatial questions that appeared in the survey and reduced the time taken to complete it. The long-standing relationship between participants and the research team improved comfort to disclose sensitive geographic information related to drug use and sex. Participants in the cognitive interviews highlighted how trust and inclusive and validating language in the survey alleviated concerns related to privacy and representation.

Conclusions

This study provides promising results regarding the feasibility of using a web-based mapping survey to collect sensitive location information relevant to ending the HIV epidemic. Data collection at several geographic levels will allow for insights into spatial recall of behaviors as well as future sensitivity analysis of the spatial scale of hotspots and network characteristics. This design also promotes the privacy and comfort of participants who provide location information for sensitive topics. Key considerations for implementing this type of survey include trust from participants, community partners, or research teams to overcome concerns related to privacy and comfort. The implementation of similar surveys should consider local characteristics and knowledge when crafting the geospatial components.

Schmitz JM, Stotts AL, Yoon J, Northrup TF, Villarreal Y, Yammine L, Weaver MF, Carmody T, Shoptaw S, Trivedi MH. Naltrexone plus bupropion reduces cigarette smoking in individuals with methamphetamine use disorder: A secondary analysis from the CTN ADAPT-2 trial. J Subst Use Addict Treat. 2023 Feb 21:208987. Epub ahead of print. PMID: 36822269.

Abstract:

Introduction: Methamphetamine (MA) use is marked by high rates of comorbid tobacco smoking, which is associated with more severe drug use and worse clinical outcomes compared to single use of either drug. Research has shown the combination of naltrexone plus oral bupropion (NTX-BUP) improves smoking cessation outcomes in non-MA-using populations. In the Accelerated Development of Additive Pharmacotherapy Treatment (ADAPT-2) study, NTX-BUP successfully reduced MA use. Our aim in this secondary data analysis was to examine changes in cigarette smoking among the subgroup of participants reporting comorbid tobacco use in the ADAPT-2 trial.

Methods: The multi-site ADAPT-2 study used a randomized, double blind, sequential parallel comparison design to evaluate treatment with extended-release injectable NTX (380 mg every 3 weeks) combined with once-daily oral extended-release BUP (450 mg/day) vs matching injectable and oral placebo in outpatients with moderate or severe MA use disorder. The study assessed smoking outcomes, based on self-reported timeline followback (TLFB) data, twice/week for 13 weeks.

Results: Of the 403 participants in the ADAPT-2 trial, 290 reported being current cigarette smokers (71.9 %). The study found significant differences (p’s < 0.0001) for each smoking outcome indicating greater change in the proportion of nonsmoking days, number of cigarettes smoked per week, and consecutive nonsmoking days, all favoring the group receiving NTX-BUP versus placebo.

Conclusions: NTX-BUP was associated with significant reductions in self-reported cigarette smoking in the context of concurrent treatment for MA use disorder. These off-target medication effects warrant prospective investigation using biochemically confirmed measures of smoking abstinence. The development of NTX-BUP as a co-addiction treatment strategy has a potential for high public health impact.

Blair KJ, Torres TS, Hoagland B, Bezerra DRB, Veloso VG, Grinsztejn B, Clark J, Luz PM. Moderating Effect of Pre-Exposure Prophylaxis Use on the Association Between Sexual Risk Behavior and Perceived Risk of HIV Among Brazilian Gay, Bisexual, and Other Men Who Have Sex With Men: Cross-Sectional Study. JMIR Public Health Surveill. 2023 Oct 5;9:e45134. PMID: 37796573; PMCID: PMC10587815.

Abstract

Background: Gay, bisexual, and other men who have sex with men (MSM) with a higher perceived risk of HIV are more aware of and willing to use pre-exposure prophylaxis (PrEP). PrEP is an effective HIV prevention strategy, but there is a lack of data on how PrEP use might moderate the relationship between sexual risk behavior and perceived risk of HIV. Moreover, most studies measure perceived risk of HIV via a single question.

Objective: We estimated the moderating effect of PrEP use on the association between sexual risk behavior and perceived risk of HIV, measured with the 8-item Perceived Risk of HIV Scale (PRHS), among Brazilian MSM.

Methods: A cross-sectional, web-based survey was completed by Brazilian Hornet app users aged ≥18 years between February and March 2020. We included data from cisgender men who reported sex with men in the previous 6 months. We evaluated the moderating effect of current PrEP use on the association between sexual risk behavior, measured via the HIV Incidence Risk Index for MSM (HIRI-MSM), and perceived risk of HIV, measured by the PRHS. Higher HIRI-MSM (range 0-45) and PRHS (range 10-40) scores indicate greater sexual behavioral risk and perceived risk of HIV, respectively. Both were standardized to z scores for use in multivariable linear regression models.

Results: Among 4344 cisgender MSM, 448 (10.3%) were currently taking PrEP. Current PrEP users had a higher mean HIRI-MSM score (mean 21.0, SD 9.4 vs mean 13.2, SD 8.1; P<.001) and a lower mean PRHS score (mean 24.6, SD 5.1 vs mean 25.9, SD 4.9; P<.001) compared to those not currently taking PrEP. In the multivariable model, greater HIRI-MSM scores significantly predicted increased PRHS scores (β=.26, 95% CI 0.22-0.29; P<.001). PrEP use moderated the association between HIRI-MSM and PRHS score (interaction term β=-.30, 95% CI -0.39 to -0.21; P<.001), such that higher HIRI-MSM score did not predict higher PRHS score among current PrEP users.

Conclusions: Our results suggest current PrEP users have confidence in PrEP’s effectiveness as an HIV prevention strategy. PrEP’s effectiveness, positive psychological impact, and the frequent HIV testing and interaction with health services required of PrEP users may jointly influence the relationship between sexual risk behavior and perceived risk of HIV among PrEP users.

Shover CL, Friedman JR, Romero R, Buhr R, Chu B, Tang A, Medina JA, Wisk L, Lucas J, Goodman-Meza D. Longitudinal changes in co-involved drugs, comorbidities, and demographics of methamphetamine-related deaths in Los Angeles County. J Subst Use Addict Treat. 2023 Aug;151:209101. doi: 10.1016/j.josat.2023.209101. Epub 2023 Jun 12. PMID: 37315796; PMCID: PMC10623547.

Abstract

Introduction: We conducted a population-based observational study of all medical examiner cases in Los Angeles County from January 2012 through June 2021 in which methamphetamine was listed as a cause of or contributing factor to death (n = 6125). We aimed to characterize demographics, comorbidities, and co-involved substances in methamphetamine-related deaths longitudinally in Los Angeles County, California.

Methods: We used detailed death record data to manually classify fatalities by involvement of each organ system, opioids, alcohol, cocaine, other drugs or medications, and external/traumatic causes. Primary outcomes included: the number of methamphetamine-involved deaths, demographics of decedents, percentage of methamphetamine deaths also involving other drugs, and percentage of methamphetamine deaths involving different organ systems. We performed Mann Kendall tests of trends to identify statistically significant longitudinal changes.

Results: During the study period, the percentage of methamphetamine-related deaths involving opioids significantly increased from 16 % in 2012 to 54 % in 2021 (p < 0.001). Concurrently, the percentage involving cardiovascular causes significantly decreased from 47 % to 26 % (p < 0.05). Methamphetamine-related deaths in LAC increasingly affected people experiencing homelessness, for whom the percentage tripled from 13 % in 2012 to 35 % in 2021. The share of decedents under 40 years old increased from 33 % to 41 %. The percentage of Black or African American decedents increased over five-fold from 3 % to 17 %.

Conclusions: Methamphetamine-related deaths involving opioids more than tripled in Los Angeles County from 2012 to 2021, reflecting the drug supply’s shift to illicit fentanyl. More than a quarter involved cardiovascular causes. These findings have implications for treatment and prevention, including scaling up contingency management, distributing naloxone to people who primarily use stimulants, and including cardiovascular care alongside these interventions directly targeted to reduce harms of methamphetamine use.

Meireles P, Ware D, Henriques A, Nieves-Lugo K, Stosor V, Brennan-Ing M, Meanley S, Haberlen S, Okafor CN, Shoptaw S, Friedman MR, Plankey M. Loneliness and Frailty Among Middle-Aged and Aging Sexual Minority Men Living With or Without HIV: A Longitudinal Cross-Lagged Panel Analysis. Innov Aging. 2023 Oct 21;7(9):igad113.  PMCID: PMC10652703.

Abstract

Background and Objectives

Loneliness is associated with frailty among older adults (60+), and there is evidence suggesting that this association may be bidirectional. However, there is limited evidence of this relationship over time among middle-aged and aging sexual minority men. We explored the bidirectional relationship between loneliness and frailty over 2 years among sexual minority men living with or without human immunodeficiency virus (HIV) from the Healthy Aging substudy of the Multicenter AIDS Cohort Study.

Research Design and Methods

We used data from 1 118 men (561 living with HIV; 557 living without HIV) aged 40 years or older with measurement of frailty or loneliness at Times 1 (September 2016 to March 2017) and 2 (September 2018 to March 2019). Descriptive statistics were generated. We used autoregressive cross-lagged panel analysis to examine the bidirectional association between frailty and loneliness at both time points while adjusting for time-stable and time-dependent covariates at Time 1. Adjusted odds ratios (aORs) and 95% confidence intervals (CIs) were generated.

Results

The estimated prevalence of loneliness at both time points was 35.5%. The estimated prevalence of frailty at Times 1 and 2 were 7.8% and 12.1%, respectively. Participants reporting loneliness at Time 1 had greater odds of being frail at Time 2 (aOR = 2.14; 95% CI: 1.23–3.73). Frailty at Time 1 was not associated with loneliness at Time 2 (aOR = 1.00; 95% CI: .44–2.25). The autoregressive effects of frailty (aOR = 23.43; 95% CI: 11.94–46) and loneliness (aOR = 13.94; 95% CI: 9.42–20.61) were large.

Discussion and Implications

Men who felt lonely had higher odds of being frail 2 years later while the reciprocal association was not shown. This suggests that loneliness preceded frailty and not the other way around. Early and frequent assessments of loneliness may present opportunities for interventions that minimize the risk of frailty among sexual minority men living with and without HIV.

Intersections between syndemic conditions and stages along the continuum of overdose risk among women who inject drugs in Mexicali, Mexico. Harm reduction journal20(1), 79.

Abstract: 

Background: Research on women who inject drugs is scarce in low- and middle-income countries. Women experience unique harms such as sexism and sexual violence which translate into negative health outcomes. The present work aims to provide insight into the experiences of women who inject drugs at the US–Mexico border to identify social and health-related risk factors for overdose to guide harm reduction interventions across the Global South.

Methods: We recruited 25 women ≥ 18 years of age accessing harm reduction and sexual health services at a non-governmental harm reduction organization, “Verter”, in Mexicali, Mexico. We employed purposeful sampling to recruit women who inject drugs who met eligibility criteria. We collected quantitative survey data and in-depth interview data. Analyses of both data sources involved the examination of descriptive statistics and thematic analysis, respectively, and were guided by the syndemic and continuum of overdose risk frameworks.

Results: Survey data demonstrated reports of initiating injection drug use at a young age, experiencing homelessness, engaging in sex work, being rejected by family members, experiencing physical violence, injecting in public spaces, and experiencing repeated overdose events. Interview data provided evidence of stigma and discrimination toward women, a lack of safe spaces and support systems, risk of overdose-related harms, sexual violence, and the overall need for harm reduction services.

Conclusion: Women who inject drugs in Mexicali describe experiences of violence, overdose, and public injecting. Women are particularly vulnerable in the Mexicali context, as this area faces a noticeable lack of health and social services. Evidenced-based harm reduction strategies such as safe consumption sites and overdose prevention strategies (e.g., naloxone distribution and training) may benefit this population. Evidence from local organizations could help close the gap in service provision in low-resource settings like Mexico, where government action is almost nonexistent.

Implementing a decentralized opioid overdose prevention strategy in Mexico, a pending public policy issue. Lancet Reg Health Am. 2023 Jun 17;23:100535. doi: 10.1016/j.lana.2023.100535. PMID: 37351156; PMCID: PMC10282171.

Abstract:

The public health crisis due to opioid overdose is worsening in Mexico’s northern region due to the introduction of illicitly manufactured fentanyl into the local drug supply. Though there is an increase in overdose deaths, there is no accurate report of overdoses by Mexican government agencies and no comprehensive opioid overdose prevention strategy. There is currently only an anti-drug marketing strategy which is likely insufficient to mitigate the growing epidemic. In order to address the growing opioid overdose crisis in the country, it is necessary to create and implement a decentralized prevention strategy, that includes naloxone distribution, expanded treatment services in regions most in need, and create active dialogue with community organisations already implementing harm reduction actions. Decisive action must be taken by the Mexican government to ensure the health and wellbeing of the Mexican citizens, especially those at high risk for opioid overdose.

Abstract

Background

Opioid Agonist Treatment (OAT) combines opioid agonist medications with counseling and therapy for a whole-patient approach to treating opioid use disorder. The war in Ukraine threatened the continuity of care and well-being of individuals receiving OAT. This study aimed to capture patients’ experiences accessing OAT during the war in Ukraine to provide insights that can inform and improve the programs that serve them.

Methods

In October – November 2022, we conducted semi-structured interviews with 17 OAT patients who are peer advocates in the Ukrainian Patient Network VOLNA. All interviews were conducted virtually via Zoom, recorded, and transcribed. Through thematic analysis, we generated codes from the transcripts, iteratively using both inductive and deductive approaches.

Results

The qualitative interviews revealed four themes: 1) ‘medication,’ focusing on concerns about availability, dosage, and quality of OAT; 2) ‘patient barriers,’ discussing access challenges for specific patient groups, such as refugees or patients living under the occupation; 3) ‘clinic-level challenges,’ involving dosing adequacy, treatment continuity, patient volume, and clinician stigma, and 4) ‘regulatory inflexibility,’ describing uneven implementation of regulations and increased policing to receive OAT during the war.

Conclusion

Our study emphasizes the importance of adapting OAT programs in Ukraine to better serve vulnerable patients affected by the war. The Russian invasion has severely disrupted OAT provision, increasing the risks of opioid withdrawal, overdose, and diversion. By understanding patients’ experiences, treatment preferences, and barriers to care, OAT programs can provide continuity of care to those in need.

HIV Prevention and Care Among Black Cisgender Sexual Minority Men and Transgender Women: Protocol for an HIV Status-Neutral Cohort Study Using an Observational-Implementation Hybrid Approach. JMIR Res Protoc. 2023 Dec 1;12:e48548. doi: 10.2196/48548. PMID: 38039075.

Abstract

Background: Black cisgender gay, bisexual, and other sexual minority men (SMM) and transgender women (TW) continue to be heavily affected by HIV. Further research is needed to better understand HIV prevention and care outcomes in this population. In particular, there is a need for research examining the impact of substance use and sleep health on HIV prevention and treatment outcomes among Black SMM and TW.

Objective: This paper outlines the study methods being used in the recently launched follow-up study to the Neighborhoods and Networks (N2) study, which we refer to as N2 Part 2 (N2P2). N2P2 aims to address this gap in the literature, build off the findings of the original N2 study, and identify socioenvironmental determinants of health, including whether neighborhood and network factors mediate and moderate these relationships.

Methods: Building on the N2 cohort study in Chicago from 2018 to 2022, N2P2 used a prospective longitudinal cohort design and an observational-implementation hybrid approach. With sustained high levels of community engagement, we aim to recruit a new sample of 600 Black SMM and TW participants residing in the Chicago metropolitan statistical area. Participants are asked to participate in 3 study visits across an 18-month study period (1 visit every 9 months). Four different forms of data are collected per wave: (1) an in-person survey, (2) biological specimen collection, (3) a daily remote ecological momentary assessment for 14 days after each study visit, and (4) data from electronic health records. These forms of data collection continue to assess neighborhood and network factors and specifically explore substance use, sleep, immune function, obesity, and the implementation of potential interventions that address relevant constructs (eg, alcohol use and pre-exposure prophylaxis adherence).

Results: The N2P2 study was funded in August 2021 by the National Institute of Drug Abuse (R01DA054553 and R21DA053156) and National Heart, Lung, and Blood Institute (R01HL160325). This study was launched in November 2022. Recruitment and enrollment for the first wave of data collection are currently ongoing.

Conclusions: The N2P2 study is applying innovative methods to comprehensively explore the impacts of substance use and sleep health on HIV-related outcomes among an HIV status-neutral cohort of Black SMM and TW in Chicago. This study is applying an observational-implementation hybrid design to help us achieve findings that support rapid translation, a critical priority among populations such as Black SMM and TW that experience long-standing inequities with regard to HIV and other health-related outcomes. N2P2 will directly build off the findings that have resulted from the original N2 study among Black SMM and TW in Chicago. These findings provide a better understanding of multilevel (eg, individual, network, and neighborhood) factors that contribute to HIV-related outcomes and viral suppression among Black SMM and TW.

High Vaccine Confidence Is Associated with COVID-19 Vaccine Uptake in Gay, Bisexual, and Other Men Who Have Sex with Men Who Use Substances. LGBT Health. 2023 Mar 28;10(6):480–5. Epub ahead of print. PMID: 36976808; PMCID: PMC10468549.

Abstract

Purpose: We examined associations between vaccine confidence and COVID-19 vaccine uptake among gay, bisexual, and other men who have sex with men (GBMSM).

Methods: Computer-assisted self-interviews were conducted among 249 GBMSM participating in mSTUDY from May to October 2021—a cohort of GBMSM with a history of substance use in Los Angeles. Data were collected using a vaccine confidence index. The association between vaccine confidence and COVID-19 vaccine uptake was assessed using multivariable log-binomial regression.

Results: Two-thirds (64.7%) of GBMSM reported receiving at least one dose of COVID-19 vaccine. Vaccine confidence was positively associated with COVID-19 vaccine uptake. Participants expressed neutral attitudes on government trust and vaccine safety. Perceived health benefit and vaccine effectiveness were statistically significantly associated with vaccine uptake (adjusted prevalence ratio [APR] = 1.59, 95% confidence interval [CI]: 1.20–2.16; APR = 1.51, 95% CI: 1.07–2.15).

Conclusions: Public health programs should prioritize public benefit and vaccine effectiveness messaging to advance vaccination among GBMSM who use substances.

Abstract

Objectives: Gender-affirming hormonal therapies (GAHT) and HIV increase cardiovascular risk for transgender women (TW), yet there is a paucity of data quantifying cardiometabolic changes following GAHT initiation, particularly among TW with HIV.

Methods: The Féminas study enrolled TW from October 2016 to March 2017 in Lima, Peru. Participants reported sexual activity that was high risk for HIV acquisition or transmission. All were tested for HIV/ sexually transmitted infection and were given access to GAHT (oestradiol valerate and spironolactone), HIV pre-exposure prophylaxis (PrEP) or antiretroviral therapy (ART) for 12 months. Biomarker measurement was done on stored serum, whereas fasting glucose and lipids were measured in real time.

Results: In all, 170 TW (32 with HIV, 138 without HIV) had median age 27 years and 70% prior GAHT use. At baseline, PCSK9, sCD14, sCD163, IL-6, sTNFRI/II, CRP and EN-RAGE levels were significantly higher in TW with HIV than in TW without HIV. High-density lipoprotein and total cholesterol were lower and insulin and glucose parameters were similar. All TW with HIV started ART, but only five achieved virological suppression at any time. No TW without HIV initiated PrEP. Over 6 months, all participants initiated GAHT and had worsening insulin, glucose and HOMA-IR. Large d-dimer decreases also occurred. Similar changes occurred in TW with and without HIV.

Conclusions: In this unique cohort of TW, GAHT decreased d-dimer but worsened insulin sensitivity. Because PrEP uptake and ART adherence were very low, observed effects are primarily attributed to GAHT use. Further study is needed to better understand cardiometabolic changes in TW by HIV serostatus.

Fentanyl, heroin, and methamphetamine-based counterfeit pills sold at tourist-oriented pharmacies in Mexico: An ethnographic and drug checking study. Drug Alcohol Depend. 2023 Aug 1;249:110819. doi: 10.1016/j.drugalcdep.2023.110819. Epub 2023 Jun 9. PMID: 37348270; PMCID: PMC10368172.

Abstract:

Background

Fentanyl- and methamphetamine-based counterfeit prescription drugs have driven escalating overdose death rates in the US, however their presence in Mexico has not been assessed. Our ethnographic team has conducted longitudinal research focused on illicit drug markets in Northern Mexico since 2018. In 2021–2022, study participants described the arrival of new, unusually potent tablets sold as ostensibly controlled substances, without a prescription, directly from pharmacies that cater to US tourists.

Aims

To characterize the availability of counterfeit and authentic controlled substances at pharmacies in Northern Mexico available to English-speaking tourists without a prescription.

Methods

We employed an iterative, exploratory, mixed methods design. Longitudinal ethnographic data was used to characterize tourist-oriented micro-neighborhoods and guide the selection of n=40 pharmacies in n=4 cities in Northern Mexico. In each pharmacy, samples of “oxycodone”, “Xanax”, and “Adderall” were sought as single pills, during English-language encounters, after which detailed ethnographic accounts were recorded. We employed immunoassay-based testing strips to check each pill for the presence of fentanyls, benzodiazepines, amphetamines, and methamphetamines. We used Fourier-Transform Infrared Spectroscopy to further characterize drug contents.

Results

Of n=40 pharmacies, one or more of the requested controlled substance could be obtained with no prescription (as single pills or in bottles) at 28 (70.0%) and as single pills at 19 (47.5%). Counterfeit pills were obtained at 11 pharmacies (27.5%). Of n=45 samples sold as one-off controlled substances, 18 were counterfeit. 7 of 11 (63.6%) samples sold as “Adderall” contained methamphetamine, 8 of 27 (29.6%) samples sold as “Oxycodone” contained fentanyl, and 3 “Oxycodone” samples contained heroin. Pharmacies providing counterfeit drugs were uniformly located in tourist-serving micro-neighborhoods, and generally featured English-language advertisements for erectile dysfunction medications and “painkillers”. Pharmacy employees occasionally expressed concern about overdose risk and provided harm reduction guidance.

Discussion

The availability of fentanyl-, heroin-, and methamphetamine-based counterfeit medications in tourist-oriented independent pharmacies in Northern Mexico represents a public health risk, and occurs in the context of 1) the normalization of medical tourism as a response to rising unaffordability of healthcare in the US, 2) plummeting rates of opioid prescription in the US, affecting both chronic pain patients and the availability of legitimate pharmaceuticals on the unregulated market, 3) the rise of fentanyl-based counterfeit opioids as a key driver of the fourth, and deadliest-to-date, wave of the opioid crisis. It was not possible to distinguish counterfeit medications based on appearance of pills or geography of pharmacies, because identically-appearing authentic and counterfeit versions were often sold in close geographic proximity. Nevertheless, drug consumers may be more trusting of controlled substances purchased directly from pharmacies. Due to Mexico’s limited opioid overdose surveillance infrastructure, the current death rate from these substances remains unknown.

Walker D, Moucheraud C, Butler D, de Vente J, Tangonan K, Shoptaw S, Currier JS, Gladstein J, Hoffman R. Experiences with telemedicine for HIV care in two federally qualified health centers in Los Angeles: a qualitative study. BMC Health Serv Res. 2023 Feb 15;23(1):156. PMID: 36793080; PMCID: PMC9930012.

Abstract: 

Background: The SARS-CoV-2 pandemic has resulted in an increase in telemedicine utilization for routine HIV care. However, there is limited information on perceptions of and experiences with telemedicine from United States (U.S.) federally qualified health centers (FQHCs) offering HIV care. We sought to understand telemedicine experiences of stakeholders with various roles: people living with HIV (PLHIV), clinical (clinicians and case managers), programmatic (clinic administrators), and policy (policymakers).

Methods: Qualitative interviews about benefits and challenges of telemedicine (telephone and video) for HIV care were conducted with 31 PLHIV and 23 other stakeholders (clinicians, case managers, clinic administrators, and policymakers). Interviews were transcribed, translated to English if conducted in Spanish, coded, and analyzed for major themes.

Results: Almost all PLHIV felt capable of engaging in telephone visits, with some expressing interest in learning how to use video visits as well. Nearly all PLHIV wanted to continue telemedicine as part of their routine HIV care, and this was also endorsed by clinical, programmatic and policy stakeholders. Interviewees agreed that telemedicine for HIV care has benefits for PLHIV, especially savings of time and transportation costs, which also reduced stress. Clinical, programmatic, and policy stakeholders expressed concerns around patients’ technological literacy and resources, as well as their access to privacy, and some felt that PLHIV strongly preferred in-person visits. These stakeholders also commonly reported clinic-level implementation challenges, including integrating telephone and video telemedicine into workflows and difficulty with video visit platforms.

Conclusions: Telemedicine for HIV care, largely delivered via telephone (audio-only), was highly acceptable and feasible for both PLHIV, clinicians, and other stakeholders. Addressing barriers for stakeholders in incorporating video visits will be important for the successful implementation of telemedicine with video as part of routine HIV care at FQHCs.

Examining the Role of Autonomy Support, Goal Setting, and Care Coordination Quality on HIV PrEP Adherence in Black Men Who Have Sex with Men: HPTN 073. AIDS Patient Care STDS. 2023 Jan;37(1):22-30. PMID: 36626154.

Abstract: 

Autonomy support is a concept that is derived from self-determination theory. Autonomy refers to the freedom to act as one chooses. The current study aimed to examine if autonomy support was associated with dried blood spot validated pre-exposure prophylaxis (PrEP) adherence, and whether the association was mediated by PrEP adherence goal setting and progress toward PrEP adherence goals. Our sample was drawn from Black men who have sex with men (MSM) from across three cities (Chapel Hill, NC; Los Angeles, CA; and Washington, DC) in the United States between February 2013 and September 2014. We used logistic regression to evaluate associations between study variables and path analysis to test mediation effects. Participants were, on average, 28 [standard deviation (SD) = 1.12] years old and 25% were unemployed. We found that MSM who experienced high autonomy support were more likely to adhere to PrEP [odds ratio (OR) = 1.17; 95% confidence interval: 1.00-1.38]. MSM who set PrEP adherence goals were more likely to adhere to PrEP. Moreover, MSM who reported making progress toward their goals were also more likely to adhere to PrEP. Finally, client perception of coordination quality enhanced the magnitude of the association between goal setting and goal progress and the effect size of goal progress on PrEP adherence. Autonomy support, goal setting, goal monitoring/evaluation, and care coordination quality influenced PrEP adherence among Black MSM. Our findings indicate that while it is important to set goals for PrEP adherence, goal setting may need to be accompanied by progress monitoring to achieve the maximal effect.

Evaluating the agreement between different substance use recall periods in multiple HIV cohorts. Drug Alcohol Depend. 2023 Nov 30;254:111043. doi: 10.1016/j.drugalcdep.2023.111043. Epub ahead of print. PMID: 38061201.

Abstract

Background: This study aims to evaluate the agreement in substance use on both binary and ordinal scales between 3-month and 6-month recall periods with samples from different communities, demographic backgrounds, and HIV status.

Methods: We administered the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) to 799 participants from three different North American cohorts focused on substance use and HIV. We conducted a within-person agreement analysis by calculating the agreement levels and Kappa statistic between data collected using the 3-month recall ASSIST and 6-month custom substance use surveys as well as different terminology for each substance in multiple cohorts.

Results: For all drugs studied, the agreement on the binary use or ordinal frequency of use metrics showed a high agreement level between 80.4% and 97.9% and an adequate adjusted kappa value between 0.61 and 0.96, suggesting substantial agreement. According to the agreement criteria we proposed, substance use data collected using different recall periods and with variation in drug names can be harmonized across cohorts.

Conclusions: This study is the first to evaluate the feasibility of data harmonization of substance use by demonstrating high level of agreement between different recall periods in different cohorts. The results can inform data harmonization efforts in consortia where data are collected from cohorts using different questions and recall periods.

Abstract

Family rejection has negative health consequences for Latinx sexual minority men (LSMM). However, LSMM often reconcile with their families, a phenomenon cross-sectional studies miss. We analyzed longitudinal data from the Healthy Young Men’s Study in Los Angeles. We used individual fixed-effects Poisson regression to model changes over time in the associations among family support, drug use, and depressive symptoms. We found that (1) the initiation of drug use was associated with a 7.2% (Ratio=1.072, 95% CI 1.006 – 1.142, p = 0.03) increase in family support among LSMM who reported high depressive symptoms (depression subscale T-score ≥ 63) in at least one data wave; (2) a 1-unit increase in family support was associated with a 4.7% (RR = ;0.953, 95% CI 0.931 – 0.976, p < 0.001) decrease in the probability of high depressive symptoms; and (3) no significant association between a change in drug use and a change in high depressive symptoms. Over time, LSMM appear to benefit from the health effects of family support associated with Latinx family structures.

Li MJ, Hassan A, Javanbakht M, Gorbach PM, Shoptaw SJ. Decision-making task performance and patterns of methamphetamine use in people assigned male at birth who have sex with men. Exp Clin Psychopharmacol. 2023 Nov 2. Epub ahead of print. PMID: 37917508.

Abstract

This study aims to determine whether performance on the Iowa Gambling Task (IGT), a simulation of risk-taking when faced with loss, is associated with greater frequency of methamphetamine (MA) use and challenges reducing or stopping MA use. The parent mSTUDY is a Los Angeles County-based longitudinal study of substance use and HIV risk in predominately Black/African American and Latinx people assigned male at birth who have sex with men. The IGT was offered for a limited timeframe to mSTUDY participants, of whom 192 consented to and completed this one-time task. Separate random intercept binary logistic regressions tested whether the IGT total score and subscore for Blocks 4 and 5 (last 40 card draws) were associated with the outcomes, testing positive for MA in urine and self-reported inability to control or cease MA use in the past 6 months. Separate random intercept ordered logistic regressions tested whether IGT total score and subscore were associated with self-reported frequency of MA use in past 6 months. Higher IGT subscores for Blocks 4 and 5 (lower risk-taking) were associated with lower odds of testing MA-positive (adjusted odds ratio, AOR = 0.97, 95% CI [0.95, 0.99], p = .025) and less frequent MA use in the past 6 months (AOR = 0.96, 95% CI [0.94, 0.99], p = .006). Higher IGT total scores (lower risk-taking) were also associated with less frequent MA use (AOR = 0.99, 95% CI [0.97, 0.99], p = .038). Findings from this analysis suggest that IGT performance may be a useful indicator of MA use severity in nontreatment-seeking people.

Co-Utilization of HIV, Substance Use, and Mental Health Services Among Women with Current Substance Use. Open Forum Infect Dis. 2023 Nov 27;10(Suppl 2):ofad500.1409. doi: 10.1093/ofid/ofad500.1409. PMCID: PMC10677561.

Abstract

Background

Integrated HIV, mental health, and substance use (SU) treatment strategies to improve health outcomes among women living with HIV (WWH) are limited. We described co-utilization of HIV, SU, and mental health treatment services among women enrolled in the Women’s Interagency HIV Study (WIHS) who report current SU.

Methods

We included data from participants enrolled in 10 WIHS sites during their last study visit from 2013-2020. Current SU was defined as self-reported, non-medical use of drugs in the past year, excluding use of only marijuana. We described utilization of each treatment service (SU treatment, HIV care, mental health care, alcohol use treatment, tobacco cessation treatment) by subgroups of participants with current SU and either HIV, depressive symptoms (Center for Epidemiologic Studies–Depression score ≥ 16), heavy alcohol use ( > 7 drinks/week), or current tobacco use. We then compared utilization of services by those who did or did not utilize SU treatment using Chi-square/Fisher exact tests.

Results

Among women with current SU (n=377), 41.9% reported utilizing SU treatment (Table) and 82.7% receiving any health care. Among women with current SU+HIV (n=233), 86.3% had an HIV healthcare provider visit since last study visit; among current SU+depressive symptoms (n=204), 39.2% had a mental health provider visit since last visit; among current SU+heavy alcohol use (n=87), 23.0% utilized alcohol treatment in the past year; and among current SU+current tobacco use (n=296), 10.1% utilized tobacco cessation treatment in the past year. Among subgroups of women with current SU who were eligible for another service, utilization of other services was significantly higher among those who utilized SU treatment for alcohol and tobacco cessation treatment, but not for any healthcare provider, HIV care, or mental health care provider.

Conclusion

Among this sample of WWH with current SU, we found 1) high engagement in SU treatment, and high engagement in health care and HIV care regardless of SU treatment, but 2) low engagement in alcohol and tobacco cessation treatments. Integrated drug, alcohol, and tobacco treatment programs should not be missed opportunities for WWH with concurrent SU, alcohol or tobacco use.

Comparing Factors Associated with Increased Stimulant Use in Relation to HIV Status Using a Machine Learning and Prediction Modeling Approach. Prev Sci. 2023 Aug;24(6):1102-1114. doi: 10.1007/s11121-023-01561-x. Epub 2023 Jun 16. PMID: 37328629

Abstract

Stimulant use is an important driver of HIV/STI transmission among men who have sex with men (MSM). Evaluating factors associated with increased stimulant use is critical to inform HIV prevention programming efforts. This study seeks to use machine learning variable selection techniques to determine characteristics associated with increased stimulant use and whether these factors differ by HIV status. Data from a longitudinal cohort of predominantly Black/Latinx MSM in Los Angeles, CA was used. Every 6 months from 8/2014-12/2020, participants underwent STI testing and completed surveys evaluating the following: demographics, substance use, sexual risk behaviors, and last partnership characteristics. Least absolute shrinkage and selection operator (lasso) was used to select variables and create predictive models for an interval increase in self-reported stimulant use across study visits. Mixed-effects logistic regression was then used to describe associations between selected variables and the same outcome. Models were also stratified based on HIV status to evaluate differences in predictors associated with increased stimulant use. Among 2095 study visits from 467 MSM, increased stimulant use was reported at 20.9% (n = 438) visits. Increased stimulant use was positively associated with unstable housing (adjusted [a]OR 1.81; 95% CI 1.27-2.57), STI diagnosis (1.59; 1.14-2.21), transactional sex (2.30; 1.60-3.30), and last partner stimulant use (2.21; 1.62-3.00). Among MSM living with HIV, increased stimulant use was associated with binge drinking, vaping/cigarette use (aOR 1.99; 95% CI 1.36-2.92), and regular use of poppers (2.28; 1.38-3.76). Among HIV-negative MSM, increased stimulant use was associated with participating in group sex while intoxicated (aOR 1.81; 95% CI 1.04-3.18), transactional sex (2.53; 1.40-2.55), and last partner injection drug use (1.96; 1.02-3.74). Our findings demonstrate that lasso can be a useful tool for variable selection and creation of predictive models. These results indicate that risk behaviors associated with increased stimulant use may differ based on HIV status and suggest that co-substance use and partnership contexts should be considered in the development of HIV prevention/treatment interventions.

Javanbakht M, Miller AP, Moran A, Ragsdale A, Bolan R, Shoptaw S, Gorbach PM. Changes in Substance Use and Sexual Behaviors After a Sexually Transmitted Infection Diagnosis Among a Cohort of Men Who Have Sex With Men in Los Angeles, CA. Sex Transm Dis. 2023 Feb 1;50(2):112-120. Epub 2022 Nov 6. PMID: 36342834; PMCID: PMC9839596.

Abstract: 

Despite declines in substance use and sexual behaviors after a sexually transmitted infection, reinfections were high suggesting that men who have sex with men with sexually transmitted infections occupy sexual networks with high transmission probabilities and prevention efforts should consider sexual network characteristics.

Background: Sexually transmitted infections (STIs), STI reinfection, human immunodeficiency virus (HIV) acquisition, and changes in behaviors after an STI were examined in a cohort of men who have sex with men (MSM) in Los Angeles, CA.

Methods: Data from a longitudinal study of MSM enrolled from 2014 with at least 1 follow-up visit through March 2020 were analyzed (n = 447; 1854 visits). Study visits every 6 months included self-interviews for sexual behaviors, substance use, and specimen collection for chlamydia, gonorrhea, syphilis, and HIV testing. Changes in behaviors were assessed using the McNemar test, and participants not diagnosed with an STI served as controls for a difference-in-difference (DiD) analysis of changes over time.

Results: Cumulative incidence of an STI was 55% (248 of 447). At 24 months after STI diagnosis, methamphetamine use declined from 50% to 35% (P < 0.01), and median number of sex partners declined from 5 (interquartile range, 2–11) to 2 (interquartile range, 1–6; P < 0.01). Among participants at risk for HIV and diagnosed with an STI (n = 102), postexposure prophylaxis use was 35% and HIV seroconversion was 6%. Based on DiD analyses, participants diagnosed with an STI had higher levels of substance and a higher number of sex partners when compared with those with no STIs; however, declines in these behaviors were comparable to participants not diagnosed with an STI (PDID > 0.05).

Conclusions: Despite behavior modifications after an STI diagnosis, STI/HIV incidence was high, suggesting that MSM with STIs occupy sexual networks where reductions in sexual and substance using behaviors do not protect them from ongoing exposure to STIs and HIV.

Changes in Inflammatory Cytokine Levels in Rectal Mucosa Associated with Neisseria Gonorrheae and/or Chlamydia trachomatis Infection and Treatment Among Men Who Have Sex with Men in Lima, Peru. J Infect Dis. 2023 Aug 16:jiad349. Epub ahead of print. PMID: 37584273.

Abstract

Background: Neisseria gonorrheae (NG) and Chlamydia trachomatis (CT) are associated with mucosal inflammation and HIV-1 transmission. We assessed levels of inflammatory cytokines in men who have sex with men (MSM) with and without rectal gonorrhea and/or chlamydia in Lima, Peru.

Methods: We screened 605 MSM reporting condomless receptive anal intercourse for rectal NG/CT using nucleic acid testing. We identified 101 cases of NG and/or CT and randomly selected 50 NG/CT (+) cases and matched 52 NG/CT (-) controls. We measured levels of IL-1β, IL-6, IL-8, and TNF-α in rectal secretions. Testing for HIV-1, rectal NG/CT, and mucosal cytokines were repeated after 3 and 6 months. Cytokine levels in cases and uninfected controls were compared using Wilcoxon Rank-Sum tests and linear regression.

Results: MSM with NG/CT had elevated levels of all cytokines in rectal mucosa compared with matched controls (all p-values <0.001). Following antibiotic treatment there were no significant differences in cytokine levels at 3- or 6-month Follow-up evaluations between case and control groups (all p-values >0.05).

Discussion: Rectal NG/CT infection is associated with transient mucosal inflammation and cytokine recruitment that resolves following treatment. Our data provides “proof of concept” for rectal STI screening as an HIV prevention strategy for MSM.

Abstract:

Background: Methamphetamine (MA) use is associated with sexual risk behavior as well as systemic and mucosal inflammation, suggesting parallel biological and behavioral mechanisms of HIV transmission among men who have sex with men (MSM) who use MA. Data evaluating the combined biological effects of MA use with concomitant rectal gonococcal and/or chlamydial (GC/CT) infection on inflammation are limited.

Setting: Secondary analysis of stored rectal and plasma specimens from 100 MSM participating in an NIDA-funded longitudinal cohort in Los Angeles, CA.

Methods: This cross-sectional analysis evaluated systemic and rectal inflammatory markers under 2 conditions: (1) recent MA use (by urine drug screen) and (2) rectal GC/CT infection. We evaluated 50 participants with recent MA use (25 with and 25 without rectal GC/CT) and 50 MSM without MA use (25 with and 25 without rectal GC/CT). Log-transformed plasma and rectal immune markers were regressed on MA exposure and rectal GC/CT, controlling for HIV status and age.

Results: Median age was 32 (range 19-45) years, and 58% of participants were living with HIV. Plasma tumor necrosis factor (TNF)-α, interleukin (IL)-6, IL-8, IL-1ß, and rectal IL-6 were associated with rectal GC/CT and MA use, independent of HIV status. Higher levels of rectal TNF-α, IL-1ß, and IL-17a were associated with rectal GC/CT.

Conclusions: Systemic and rectal inflammation was positively associated with rectal GC/CT and MA use. Condomless sex in the setting of GC/CT- and MA-induced immune activation may provide a basis for synergistic biobehavioral mechanisms that promote HIV/STI transmission among MSM who use MA.

Both/And: Mixed methods analysis of network composition, communication patterns, and socio-economic support within social networks of transgender women involved in sex work in Lima, Peru. BMC Public Health. 2023 Dec 1;23(1):2385. doi: 10.1186/s12889-023-17278-z. PMID: 38041045; PMCID: PMC10690964.

Abstract

Introduction: Social networks contribute to normative reinforcement of HIV prevention strategies, knowledge sharing, and social capital, but little research has characterized the social networks of transgender women (TW) in Latin America. We conducted a mixed methods analysis of three network clusters of TW in Lima, Peru, to evaluate network composition, types of support exchanged, and patterns of communication.

Methods: We recruited TW residing in or affiliated with three “casas trans” (houses shared among TW) in Lima between April-May 2018. Eligible participants were 18 or older, self-reported HIV-negative, and reported recent intercourse with a cis-male partner. Participants completed demographic questionnaires, social network interviews, and semi-structured interviews to assess egocentric network structures, support exchanged, and communication patterns. Quantitative and qualitative data were analyzed using Stata v14.1 and Atlas.ti, respectively.

Results: Of 20 TW, median age was 26 years and 100% reported involvement in commercial sex work. Respondents identified 161 individuals they interacted with in the past month (alters), of whom 33% were TW and 52% family members. 70% of respondents reported receiving emotional support from family, while 30% received financial support and instrumental support from family. Of the 13 (65%) respondents who nominated someone as a source of HIV prevention support (HPS), the majority (69%) nominated other TW. In a GEE regression analysis adjusted for respondent education and region of birth, being a family member was associated with lower likelihood of providing financial support (aOR 0.21, CI 0.08-0.54), instrumental support (aOR 0.16, CI 0.06-0.39), and HPS (aOR 0.18, CI 0.05-0.64). In qualitative interviews, most respondents identified a cis-female family member as their most trusted and closest network member, but other TW were more often considered sources of day-to-day support, including HPS.

Conclusion: TW have diverse social networks where other TW are key sources of knowledge sharing and support, and family members may also represent important and influential components. Within these complex networks, TW may selectively solicit and provide support from different network alters according to specific contexts and needs. HIV prevention messaging could consider incorporating network-based interventions with TW community input and outreach efforts for supportive family members.

Moran A, Javanbakht M, Mimiaga M, Shoptaw S, Gorbach PM. Association of Partnership-Level Methamphetamine Use on Inconsistent PrEP Care Engagement Among GBMSM in Los Angeles County. AIDS Behav. 2023 Oct 4. Epub ahead of print. PMID: 37792232.

Abstract

There are limited quantitative studies describing the association between meth use in the context of male-male sexual partnerships and PrEP care engagement. We assessed the longitudinal relationship between individual and partnership level meth use with inconsistent PrEP engagement among young gay, bisexual and other men who have sex with men (GBMSM) in Los Angeles. The primary exposure was meth use at the partnership level with a ternary variable (neither partner nor participant used meth, either used meth, or both used meth). Generalized estimating equations were used to assess odds of inconsistent PrEP engagement at different levels of partner-participant meth use, adjusting for age at visit, number of recent male partners and partner intimacy. Among inconsistent PrEP engagement, 61% (n = 84, vs. 79.5%, n = 346 continuous) reported that neither they nor their partner used meth, 22% (n = 31, vs. 18%, n = 56) reported that either partner or participant used meth and 17% (n = 24, vs. 8%, n = 33) reported that both partner and participant used meth (P < 0.01). There were increased odds of inconsistent PrEP engagement when both partner and participant reported meth use (aOR: 3.82; 95%CI: 1.83-7.99) and when either partner or participant reported meth use (aOR: 2.46; 95%CI: 1.28-4.75). Meth use plays an important role in consistent PrEP engagement among GBMSM in mSTUDY. PrEP users who use meth with partners may benefit from integrated interventions addressing both meth use and PrEP engagement.

Association of current substance use treatment with future reduced methamphetamine use in an observational cohort of men who have sex with men in Los Angeles. J Subst Use Addict Treat. 2023 Nov 17:209228. Epub ahead of print. PMID: 37981239.

Abstract

Introduction: Methamphetamine use is highly prevalent among men who have sex with men (MSM), but knowledge of the long-term dynamics, and how they are affected by substance use treatment, is limited. This study aimed to describe trajectories of methamphetamine use among MSM, and to evaluate the impact of treatment for any kind of substance use on frequency of methamphetamine use.

Methods: This analysis used data from a cohort of MSM in Los Angeles, CA, who participated in semi-annual study visits from 2014 to 2022. The study characterized trajectories of methamphetamine use using a continuous time multistate Markov model with three states. States were defined using self-reported frequency of methamphetamine use in the past six months: frequent (daily), occasional (weekly or less), and never. The model estimated the association between receiving treatment for any kind of substance use and changes in state of frequency of methamphetamine use.

Results: This analysis included 2348 study visits among 285 individuals who were followed-up for an average of 4.4 years. Among participants who were in the frequent use state, 65 % (n = 26) of those who were receiving any kind of substance use treatment at a study visit had reduced their methamphetamine use at their next visit, compared to 33 % (n = 95) of those who were not receiving treatment. Controlling for age, race/ethnicity, and HIV-status, those who reported receiving current treatment for substance use were more likely to transition from occasional to no use (HR: 1.63, 95 % CI: 1.10-2.42) and frequent to occasional use (HR: 3.58, 95 % CI: 2.11-8.59) in comparison to those who did not report receiving current treatment for substance use.

Conclusions: Findings from this dynamic modeling study provide a new method for assessing longitudinal methamphetamine use outcomes and add important evidence outside of clinical trials that substance use treatment may reduce methamphetamine use.

Wiss DA, Prelip ML, Upchurch DM, von Ehrenstein OS, Tomiyama AJ, Gorbach PM, Shoptaw SJ. Association between Childhood Maltreatment and Depressive and Anxiety Symptoms among Men Who Have Sex with Men in Los Angeles. J Urban Health. 2023 Feb 24:1–14. Epub ahead of print. PMID: 36826734; PMCID: PMC9951846

Abstract 

Adverse childhood experiences (ACEs) have been associated with poor mental health outcomes in adulthood. Childhood maltreatment is related to both depressive and anxiety symptoms. Our objective was to investigate these associations among low-income, mostly Black and Latino men who have sex with men (MSM), as these may be a particularly vulnerable population group. Data come from a longitudinal study of MSM with varied substance use behaviors (n = 321) collected between August 2014 and April 2022. Cumulative, childhood maltreatment ACEs, and the single ACE of childhood sexual abuse were investigated as potential predictors of self-reported depressive and anxiety symptoms in mixed-effects logistic and ordinal regression models. There was no evidence of a dose-response relationship between the number of ACEs and the predicted probability of depressive and anxiety symptoms. Compared to MSM reporting fewer than five ACEs, those with five or more ACEs had approximately double the odds ratio of reporting depressive (OR = 1.93; 95% CI: 1.04-3.60) and anxiety symptoms (OR = 2.21; 95% CI: 1.05-4.68). The dimension of childhood maltreatment had a more robust prediction of depressive symptoms than the dimension of household dysfunction across all models. The association between childhood sexual abuse history and depressive symptoms remained after adjustment for the other nine ACEs (OR = 2.27; 95% CI: 1.11-4.68). The ordinal logistic model suggested that cumulative ACEs more than triple the odds of being in a higher anxiety category (OR = 3.12; 95% CI: 1.58-6.14), with associations reported for childhood maltreatment ACEs (OR = 1.31; 95% CI: 1.06-1.66) and childhood sexual abuse (OR = 1.93; 95% CI: 0.89-4.21). Childhood maltreatment ACEs, particularly childhood sexual abuse, are salient predictors of depressive and anxiety symptoms among adult urban MSM. Mitigating the impact of childhood maltreatment requires understanding the additional burden of social distress often faced by MSM throughout the life course.

Jones AA, Santos-Lozada AR, Perez-Brumer A, Latkin C, Shoptaw S, El-Bassel N. Age-specific disparities in fatal drug overdoses highest among older black adults and American Indian/Alaska native individuals of all ages in the United States, 2015-2020. Int J Drug Policy. 2023 Feb 28;114:103977.Epub ahead of print. PMID: 36863284.

Abstract:

Introduction: Increasing disparities within and between racial/ethnic groups in overdose deaths underscore the need to identify drivers and patterns to optimize overdose prevention strategies. We assess age-specific mortality rates (ASMR) in drug overdose deaths by race/ethnicity in 2015-2019 and 2020.

Methods: Data were from the CDC Wonder, and included information for N = 411,451 deceased individuals in the United States (2015-2020) with a drug overdose-attributed cause of death (ICD-10 codes: X40-X44, X60-X64, X85, Y10-Y14). We compiled overdose death counts by age, race/ethnicity, and population estimates to derive ASMRs, mortality rate ratios (MRR), and cohort effects.

Results: The ASMRs for Non-Hispanic Black adults (2015-2019) followed a different pattern than other racial/ethnic groups-low ASMRs among young individuals and peaking between 55-64 years-a pattern exacerbated in 2020. Younger Non-Hispanic Black individuals had lower MRRs than young Non-Hispanic White individuals, yet, older Non-Hispanic Black adults had much higher MRRs than older Non-Hispanic White adults (45-54yrs:126%, 55-64yrs:197%; 65-74yrs:314%; 75-84:148%) in 2020. American Indian/Alaska Native adults had higher MRRs than Non-Hispanic White adults in death counts compiled from pre-pandemic years (2015-2019); however, MRRs increased in 2020 (15-24yrs:134%, 25-34yrs:132%, 35-44yrs:124%, 45-54yrs:134%, 55-64yrs:118%). Cohort analyses suggested a bimodal distribution of increasing fatal overdose rates among Non-Hispanic Black individuals aged 15-24 and 65-74.

Conclusions and relevance: Overdose fatalities unprecedently impact older Non-Hispanic Black adults and American Indian/Alaska Native populations of all ages, deviating from the pattern found for Non-Hispanic White individuals. Findings highlight the need for targeted naloxone and low-threshold buprenorphine programs to reduce racial disparities.

Strathdee SA, Goodman-Meza D, Rafful CM. Addressing opioid use disorder: Mexico’s step backwards. Lancet Reg Health Am. 2023 May 23;23:100520. doi: 10.1016/j.lana.2023.100520. PMID: 37497392; PMCID: PMC10366457.

Methadone and buprenorphine are considered Essential Medicines by the World Health Organization. Both are highly effective medications for treating opioid use disorder (MOUD) that significantly reduce morbidity and mortality among persons with opioid use disorder (OUD). Although access to MOUD is sub-optimal in many countries, some face unique challenges imposed by external events. In the USA, the aftermath of 9/11 and Hurricanes Katrina and Rita led to methadone dispensing interruptions that led many patients to undergo sudden opioid withdrawal and subsequent drug relapse.1,2 When Russia annexed Crimea in 2014 and assumed control over the region, methadone was immediately banned in accordance with Russia’s federal law on narcotic and psychotropic substances which prohibits its use. This sudden policy change immediately affected over 800 people who use drugs (PWUD) in Crimea who were receiving MOUD.3 A small number moved to neighbouring Ukraine to continue treatment, but the majority who could not leave rapidly underwent forced detoxification. Within a year, an estimated 80–100 people had died, some due to overdose or suicide.4

Another tragedy is unfolding, this time in Mexico. In February 2023, Mexico’s federal government closed the country’s only methadone manufacturing plant, Psicofarma, following concerns about quality control.5 In Mexican-U.S. border cities, such as Ciudad Juarez, Mexicali, and Tijuana, where the prevalence of OUD is among the highest in the country, methadone clinics are turning new clients away as they run out of medication, limiting doses, providing doses only on alternate days, or not dosing altogether. Although there are no accurate estimates of the number of persons with OUD in Mexico, a national survey in 2016 suggested that 23,251 people had used heroin in the past year.6 In 2020, 2.2% (n = 2217) of the persons that sought drug treatment in public clinics reported opioids as the main substance used, representing 42% of cases among persons who inject drugs (PWID).7 Both are likely gross under-estimates.

Although the impact of the closure of Mexico’s methadone manufacturing plant has yet to be fully realized, the potential consequences are dire for methadone clients who may be required to undergo rapid detoxification or are suddenly cut-off altogether. People receiving MOUD who relapse experience a higher risk of fatal overdose due to their reduced tolerance.1,2 The infiltration of illicitly manufactured fentanyl in Mexico further exacerbates the risk of overdose among those who experience relapse, since fentanyl is approximately fifty times more potent than heroin.

Mexico’s problems with OUD and the lack of MOUD are not theirs to bear alone. Mexico and the USA share a 2000-mile border and a binational community. Among PWID living in San Diego, California, one in six travelled to nearby Tijuana to purchase and use drugs where they are cheaper and easier to purchase.8 In north-western Mexico, pharmacies catering to drug tourists sell opiates and counterfeit drugs contaminated with opiates.9 If Mexico’s OUD related problems worsens, it will almost certainly affect the USA, which continues to face rising numbers of opioid overdose deaths.

The sudden closure of Mexico’s only methadone manufacturing plant lies bare the fault lines in its treatment of substance use disorders across the country. In 2021, there were only eleven clinics offering methadone across the country,10 with each treating approximately 400 methadone clients per year who may be affected, as well as countless others who are being turned away from services. Although the federal government had planned to expand methadone maintenance programs as part of their drug policy reform that embraced harm reduction,11 this has fallen dramatically short of expectation. Meanwhile, syringe services programs lack sufficient supplies to help PWID avoid becoming infected with HIV or viral hepatitis. The Mexican government’s official statement is that the opioid overdose reversal medication, naloxone, is “irrelevant” in Mexico given the small number of persons with OUD and that it will only benefit interest groups supporting a neoliberal agenda. Although Mexico lacks official estimates on the numbers of people with OUD and opioid overdose deaths, they are neither invisible nor negligible.

During the COVID-19 pandemic, barriers to MOUD access in the USA were sometimes overcome by relaxing restrictions on take-home doses and scaling up telehealth. Mexico should seize this opportunity to not only rectify its MOUD shortages but improve drug treatment and harm reduction services to ensure a constant supply of methadone by importing it from international suppliers, and making available other drugs for treatment of OUD, such as buprenorphine. In the interim, Mexico could maintain people on other long-acting agents such as sustained release oral morphine or hydromorphone. The international community should assist Mexico in identifying alternative sources of MOUD to reduce morbidity and mortality. Thousands of lives depend on it.

A Qualitative Study of Perceptions and Preferences Regarding Social and Behavioral Risk Screening Among Primary Care Patients. J Gen Intern Med. 2023 Nov;38(14):3171-3179. Epub 2023 Aug 14. PMID: 37578623; PMCID: PMC10651619.

Abstract

Background: Despite its relevance for healthcare settings, social and behavioral risk screening is not systematically performed by clinicians or healthcare systems.

Objective: To address clinician concerns, such as social and behavioral risk screening disrupting the clinician-patient relationship and lack of resources to respond, we interviewed primary care patients at an academic medical center regarding their perceptions and preferences on social and behavioral risk screening.

Participants: Between September and December 2020, we recruited a convenience sample of 14 English-speaking primary care patients 18 years + from three clinics affiliated with an academic medical center.

Approach: Using a semi-structured interview guide, we asked about the importance of social and behavioral risk screening, whether or not and how to share social and behavioral risk factors, and how social and behavioral risk factors are addressed. We used a multi-step analytic process to identify the range and commonality of participants’ responses thematically.

Key results: Participants recognized that social and behavioral risk factor domains were relevant to primary care and important for treating the patient as a whole person. Participants preferred a conversation regarding social and behavioral risk factor with their primary care providers (PCPs), and suggested that, if surveys are used, they be followed with an open-ended, in-person discussion. Participants also suggested framing the discussion as something that is done routinely with all patients so that patients do not feel judged. Participants felt comfortable sharing social and behavioral risk factors when they trusted their PCPs, and felt that discussing social and behavioral risk factors with their PCPs built trust. Participants recognized that resources exist outside of the clinic, and suggested that PCPs distribute lists of relevant community resources to patients.

Conclusion: In our study of primary care patients on perceptions and preferences about screening and addressing social and behavioral risk factors, we found that patients were willing to share social and behavioral risk factors with their PCP, preferred an in-person discussions with or without a survey, and wanted a list of community resources to address their needs.

Kalmin MM, Nicolo C, Long W, Bodden D, Van Nunen L, Shoptaw S, Ipser J. A Systematic Review of the Efficacy of Contingency Management for Substance Use Disorders in Low and Middle Income Countries. Int J Behav Med. 2023 Aug 2. Epub ahead of print. PMID: 37532862.

Abstract

Background: The impact of illicit substance use is especially devastating in low-resourced countries where factors such as poverty, unemployment, and inadequate services impede successful treatment. Contingency management (CM) is a treatment for substance use disorders that has shown to be effective in eliciting behaviour change. The efficacy of CM interventions in low and middle income countries (LMICs) has been under explored.

Methods: The aim of this systematic review of randomized controlled trials was to assess measures of CM efficacy in addressing substance use disorders, while also considering contextual moderators of CM in LMICs. A search of PubMed, Scopus, and Cochrane library databases yielded 18 studies for inclusion, from which relevant data were extracted using modified versions of the Cochrane Characteristics of Studies tool.

Results: Two studies were located in a low-income country, two in lower-middle income countries, and fourteen in upper middle-income countries. Overall, estimated efficacy estimates were similar to those from higher income countries. However, context-specific challenges that warrant further investigation included limited access to trained staff and structural and financial constraints.

Conclusions: While CM in LMICs is in its early stages of development, efficacy estimates were not substantially different compared to high income countries. Challenges such as costs, willingness to implement, and the stigma associated with addiction sets the stage for further research in these contexts.

Levander XA, Carmody T, Cook RR, Potter JS, Trivedi MH, Korthuis PT, Shoptaw S. A gender-based secondary analysis of the ADAPT-2 combination naltrexone and bupropion treatment for methamphetamine use disorder trial. Addiction. 2023 Mar 2. Epub ahead of print. PMID: 36864016.

Abstract:

Background and aims: Socio-cultural (gender) and biological (sex)-based differences contribute to psychostimulant susceptibility, potentially affecting treatment responsiveness among women with methamphetamine use disorder (MUD). The aims were to measure (i) how women with MUD independently and compared with men respond to treatment versus placebo and (ii) among women, how the hormonal method of contraception (HMC) affects treatment responsiveness.

Design: This was a secondary analysis of ADAPT-2, a randomized, double-blind, placebo-controlled, multicenter, two-stage sequential parallel comparison design trial.

Setting: United States.

Participants: This study comprised 126 women (403 total participants); average age = 40.1 years (standard deviation = 9.6) with moderate to severe MUD.

Interventions: Interventions were combination intramuscular naltrexone (380 mg/3 weeks) and oral bupropion (450 mg daily) versus placebo.

Measurements: Treatment response was measured using a minimum of three of four negative methamphetamine urine drug tests during the last 2 weeks of each stage; treatment effect was the difference between weighted treatment responses of each stage.

Findings: At baseline, women used methamphetamine intravenously fewer days than men [15.4 versus 23.1% days, P = 0.050, difference = -7.7, 95% confidence interval (CI) = -15.0 to -0.3] and more women than men had anxiety (59.5 versus 47.6%, P = 0.027, difference = 11.9%, 95% CI = 1.5 to 22.3%). Of 113 (89.7%) women capable of pregnancy, 31 (27.4%) used HMC. In Stage 1 29% and Stage 2 5.6% of women on treatment had a response compared with 3.2% and 0% on placebo, respectively. A treatment effect was found independently for females and males (P < 0.001); with no between-gender treatment effect (0.144 females versus 0.100 males; P = 0.363, difference = 0.044, 95% CI = -0.050 to 0.137). Treatment effect did not differ by HMC use (0.156 HMC versus 0.128 none; P = 0.769, difference = 0.028, 95% CI -0.157 to 0.212).

Conclusions: Women with methamphetamine use disorder receiving combined intramuscular naltrexone and oral bupropion treatment achieve greater treatment response than placebo. Treatment effect does not differ by HMC.

HIV Treatment Adherence Strategies Among Virally Suppressed Black Sexual Minority Men in Baltimore, Maryland, and Los Angeles, California: A Theory-Based Qualitative Study. The Journal of the Association of Nurses in AIDS Care : JANAC33(1), 54–62.

Abstract

The goals and strategies of Black sexual minority men living with HIV (BSMMLWH) who achieve viral suppression require further investigation. This study explored treatment adherence strategies among BSMMLWH with sustained viral suppression. We conducted 27 in-depth qualitative interviews with BSMMLWH in Baltimore, Maryland, and Los Angeles, California, between December 2018 and May 2019. Interviews included questions guided by Positive Deviance and Life Course theoretical frameworks regarding multilevel factors and explicit strategies for antiretroviral therapy adherence. Themes regarding intentional, age group-specific strategies such as using technology (among younger men) and taking HIV medications with other daily pills (among older men) were identified. Participants also reported symbiotic goals and values that encouraged adherence, such as having a desire to live, strong familial relationships with clinicians, and support networks. Identifying personal goals and having supportive clinical and social relationships could be key to improving treatment adherence and viral suppression among BSMMLWH.

Abstract

Background: Social genomics has demonstrated altered inflammatory and type I interferon (IFN) gene expression among people experiencing chronic social adversity. Adverse social experiences such as discrimination and violence are linked to stimulant misuse and HIV, conditions that dysregulate inflammatory and innate antiviral responses, leading to increased HIV viral replication and risk of chronic diseases.

Purpose: We aimed to determine whether methamphetamine (MA) use, unsuppressed HIV viral load (VL) (≥200 c/mL), and experienced intimate partner violence (IPV) (past 12 months) predicted inflammatory and type I IFN gene expression in HIV-positive Black and Latinx men who have sex with men (MSM).

Methods: Participants were 147 HIV-positive Black and Latinx MSM recruited from the mSTUDY, a cohort of 561 MSM aged 18–45 in Los Angeles, CA, of whom half are HIV-positive and substance-using. Transcriptomic measures of inflammatory and type I IFN activity were derived from RNA sequencing of peripheral blood mononuclear cells and matched to urine drug tests, VL, and survey data across two time points 12 months apart. Analysis used linear random intercept modeling of MA use, unsuppressed VL, and experienced IPV on inflammatory and type I IFN expression.

Results: In adjusted models, MA use predicted 27% upregulated inflammatory and 31% upregulated type I  IFN expression; unsuppressed VL predicted 84% upregulated type I  IFN but not inflammatory expression; and experienced IPV predicted 31% upregulated inflammatory and 26% upregulated type I IFN expression.

Conclusions: In Black and Latinx MSM with HIV, MA use, unsuppressed VL, and experienced IPV predicted upregulated social genomic markers of immune functioning.

Frequency of reported methamphetamine use linked to prevalence of clinical conditions, sexual risk behaviors, and social adversity in diverse men who have sex with men in Los Angeles. Drug and alcohol dependence232, 109320.

Abstract

Objective: This study tested the hypothesis that reported frequency of methamphetamine use is significantly associated with measures of social adversity, sexual risk behaviors, chronic health conditions, bacterial STIs and HIV-related factors among diverse men who have sex with men (MSM).

Methods: Data were 2428 visits from 515 mSTUDY participants (261 people living with HIV; 254 HIV-negative). mSTUDY is an ongoing longitudinal study of racially/ethnically diverse MSM in Los Angeles County. Logistic regression with random intercepts modeled associations between self-reported past 6-month methamphetamine use (none, monthly or less, weekly or more) with reported adverse social outcomes (unemployment, housing instability, intimate partner violence), sexual risk behaviors, chronic health conditions, and biomarkers of bacterial STIs (chlamydia, gonorrhea, or syphilis) and detectable HIV viral load (among HIV-positive). Models controlled for confirmed HIV-serostatus.

Results: Prevalence of reported monthly or less methamphetamine use was 19%; weekly or more use was 18%. Multivariable models showed escalating odds of adverse social outcomes and sexual risk behaviors (p’s < 0.001) with increased methamphetamine use frequency. Frequency of methamphetamine use associated with increased odds of a positive bacterial STI test (p < .001), detectable viral load (in HIV-positive participants) (p < .001), renal condition (p = .047), neurological condition (p = .008), and psychological condition (p = .001).

Conclusions: Findings show cross-sectional links between reported methamphetamine use frequency and adverse social and health outcomes among MSM in Los Angeles and suggest there may be fewer social and physical health harms corresponding to less frequent use of methamphetamine in this group.

Cannabis use, comorbidities, and prescription medication use among older adults in a large healthcare system in Los Angeles, CA 2019-2020. Journal of the American Geriatrics Society, 10.1111/jgs.17719. Advance online publication.

Abstract

Objective: To describe the reported prevalence of cannabis use and co-use with prescription medications among older adult patients attending primary care (PC) clinics in Los Angeles, CA.

Methods: We used electronic health record (EHR) data from sixty PC clinics part of a university-based, urban healthcare system. Patients’ ≥50 years of age with an annual physical examination between July 2019 and May 2020 were eligible for inclusion (n = 42,555). Cannabis use was assessed by clinic staff at the time of the visit and recorded in the EHR. We also used EHR data on clinical characteristics including current prescriptions and comorbidities.

Results: The median age was 63 years (range: 50-101) and 56% were female. Recent cannabis use was reported by 7.6%, which was higher than tobacco use (4.0%; p < 0.01). Prevalence of cannabis use was higher among patients prescribed psychotropic medications. For instance, 10.9% of patients prescribed benzodiazepines reported cannabis use as compared with 7.3% among patients without a prescription for benzodiazepines (p < 0.01). Patients with neurologic/musculoskeletal medications such as antiepileptics also had a higher prevalence of cannabis use when compared with those without these prescriptions (13.6% vs. 7.6% respectively; p < 0.01) as did those who were prescribed muscle relaxants (10.3% vs. 7.5% respectively; p < 0.01). After adjusting for age, sex, race/ethnicity, and comorbidities those prescribed medications for psychiatric (adjusted OR = 1.5; 95% CI 1.4-1.7), respiratory (adjusted OR = 1.2; 95% CI 1.1-1.3), or neurologic conditions (adjusted OR = 1.4; 95% CI 1.2-1.5) had increased odds of cannabis use compared with those not prescribed these medications.

Discussion: The prevalence of cannabis use among older adults attending PC clinics in a university-based healthcare system was higher among those prescribed medications, which may interact with cannabis. These findings suggest that key groups of older patients who may benefit from routine PC screening for cannabis use and brief advice.

Abid A, Shoptaw S and Bholat M. Creating a standard inpatient opioid withdrawal protocol [version 1; peer review: awaiting peer review]. MedEdPublish 2022, 12:7

Abstract 

BackgroundDespite safety and efficacy of medications for opioid use disorder, United States (US) hospitals face high health care costs when hospitalized patients with opioid use disorder (OUD) leave due to untreated opioid withdrawal.  Recent studies have concluded that evidence-based interventions for OUD like buprenorphine are underutilized by hospital services.
ObjectiveWe developed a practical opioid withdrawal protocol utilizing buprenorphine and the Clinical Opiate Withdrawal Scale to address opioid withdrawal during inpatient treatment of a primary medical condition. We are currently implementing this protocol at the UCLA hospital in Santa Monica.
DesignThe protocol includes order sets with appropriate and modifiable orders that can be submitted in the electronic medical record in order to deliver seamless care for opioid withdrawal. After the physician assesses the patient and initiates the protocol, nursing provides an essential role in continuing to monitor the patient’s level of withdrawal and administering the appropriate medications in response. Inpatient pharmacy is instrumental in monitoring medication administration, as well as calculating and providing dosages for orders on Day 2 and 3 of the protocol. Collaboration with case managers is essential for providing appropriate resources and ensuring a safe discharge.
Conclusion: Current challenges to widespread implementation of a standardized withdrawal protocol are discrepancies in addiction education across medical disciplines and inadequate outpatient access to buprenorphine providers and pharmacies that carry buprenorphine supplies.

Perspectives on preparing for long-acting injectable treatment for HIV among consumer, clinical and nonclinical stakeholders: A qualitative study exploring the anticipated challenges and opportunities for implementation in Los Angeles County. Plos one17(2), e0262926.

Abstract:

Long-acting injectable (LAI) antiretroviral therapy (ART) is a novel HIV treatment option for people with HIV. The first LAI ART regimen for HIV treatment received regulatory approval in the United States in January 2021. In February 2020, we collected qualitative data from 18 consumers and 23 clinical and non-clinical stakeholders to catalog anticipated individual-consumer, healthcare system, and structural levels barriers and facilitators to LAI ART implementation in Los Angeles County, California. Thematic analysis was guided by the CFIR implementation science model. CFIR constructs of intervention characteristics, individual characteristics, outer and inner setting, intervention characteristics, and implementation process emerged in analysis. Under intervention characteristics, anticipated facilitators included the relative advantage of LAI ART over pills for adherence and reduced treatment management burden and related anxiety; anticipated barriers included non-adherence to injection appointments, concerns of developing HIV resistance, discomfort with injection and cost. Anticipated facilitators based on individual characteristics included overall acceptability based on knowledge and positive beliefs about LAI ART. Participant noted several characteristics of the outer setting that could negatively impact implementation, such as medical mistrust, external policies, and LAI ART eligibility (i.e., to be virally suppressed prior to initiation). Participants were optimistic about the potential to decrease stigma but expressed that provider willingness for adoption could be hindered by challenges in organizational inner setting related to payment authorizations, increased staffing needs, medication procurement and storage, and provider and healthcare system readiness. Results from this pre-implementation study may inform rollout and scale-up of LAI ART in Los Angeles County.

Prehospital Buprenorphine Treatment for Opioid Use Disorder by Paramedics: First Year Results of the EMS Buprenorphine Use Pilot. Prehospital emergency care : official journal of the National Association of EMS Physicians and the National Association of State EMS Directors, 1–12. Advance online publication.

Abstract

Background: Prehospital initiation of buprenorphine treatment for Opioid Use Disorder (OUD) by paramedics is an emerging potential intervention to reach patients at greatest risk for opioid-related death. Emergency Medical Services (EMS) patients who are at high risk for overdose deaths may never engage in treatment as they frequently refuse transport to the hospital after naloxone reversal. The potentially important role of EMS as the initiator for medication for opioid use disorder (MOUD) in the most high-risk patients has not been well described.

Setting: This project relies on four interventions: a public access naloxone distribution program, an electronic trigger and data sharing program, an “Overdose Receiving Center,” and a paramedic initiated buprenorphine treatment. For the final intervention, paramedics followed a protocol based pilot which had an EMS physician consultation prior to administration.

Results: There were 36 patients enrolled in the trial study in the first year who received buprenorphine. Of those patients receiving buprenorphine, only one patient signed out against medical advice on scene. All other patients were transported to an emergency department and their clinical outcome and 7 and 30 day follow ups were determined by the substance use navigator (SUN.) 36 of 36 patients had follow up data obtained in the short term and none experienced any precipitated withdrawal or other adverse outcomes. Patients had a 50% (18/36) rate of treatment retention at 7 days and 36% (14/36) were in treatment at 30 days.

Conclusion: In this small pilot project, paramedic initiated buprenorphine in the setting of data sharing and linkage with treatment appears to be a safe intervention with a high rate of ongoing outpatient treatment for risk of fatal opioid overdoses.

Abstract

Background: The antibody-mediated prevention (AMP) studies (HVTN 703/HPTN 081 and HVTN 704/HPTN 085) are harmonized phase 2b trials to assess HIV prevention efficacy and safety of intravenous infusion of anti-gp120 broadly neutralizing antibody VRC01. Antibodies for other indications can elicit infusion-related reactions (IRRs), often requiring premedication and limiting their application. We report on AMP study IRRs.

Methods: From 2016 to 2018, 2699 HIV-uninfected, at-risk men and transgender adults in the Americas and Switzerland (704/085) and 1924 at-risk heterosexual women in sub-Saharan Africa (703/081) were randomized 1:1:1 to VRC01 10 mg/kg, 30 mg/kg, or placebo. Participants received infusions every 8 weeks (n = 10/participant) over 72 weeks, with 104 weeks of follow-up. Safety assessments were conducted before and after infusion and at noninfusion visits. A total of 40,674 infusions were administered.

Results: Forty-seven participants (1.7%) experienced 49 IRRs in 704/085; 93 (4.8%) experienced 111 IRRs in 703/081 (P < 0.001). IRRs occurred more frequently in VRC01 than placebo recipients in 703/081 (P < 0.001). IRRs were associated with atopic history (P = 0.046) and with younger age (P = 0.023) in 703/081. Four clinical phenotypes of IRRs were observed: urticaria, dyspnea, dyspnea with rash, and “other.” Urticaria was most prevalent, occurring in 25 (0.9%) participants in 704/085 and 41 (2.1%) participants in 703/081. Most IRRs occurred with the initial infusion and incidence diminished through the last infusion. All reactions were managed successfully without sequelae.

Conclusions: IRRs in the AMP studies were uncommon, typically mild or moderate, successfully managed at the research clinic, and resolved without sequelae. Analysis is ongoing to explore potential IRR mechanisms.

J., Leibowitz, A., Li, L., Lin, C., Li, M., Do Van Dung, & Shoptaw, S. (2022). An adaptive design to screen, treat, and retain people with opioid use disorders who use methamphetamine in methadone clinics (STAR-OM): study protocol of a clinical trial. Trials23(1), 342.

Abstract:

Background: Methamphetamine use could jeopardize the current efforts to address opioid use disorder and HIV infection. Evidence-based behavioral interventions (EBI) are effective in reducing methamphetamine use. However, evidence on optimal combinations of EBI is limited. This protocol presents a type-1 effectiveness-implementation hybrid design to evaluate the effectiveness, cost-effectiveness of adaptive methamphetamine use interventions, and their implementation barriers in Vietnam.

Method: Design: Participants will be first randomized into two frontline interventions for 12 weeks. They will then be placed or randomized to three adaptive strategies for another 12 weeks. An economic evaluation and an ethnographic evaluation will be conducted alongside the interventions.

Participants: We will recruit 600 participants in 20 methadone clinics.

Eligibility criteria: (1) age 16+; (2) Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) scores ≥ 10 for methamphetamine use or confirmed methamphetamine use with urine drug screening; (3) willing to provide three pieces of contact information; and (4) having a cell phone.

Outcomes: Outcomes are measured at 13, 26, and 49 weeks and throughout the interventions. Primary outcomes include the (1) increase in HIV viral suppression, (2) reduction in HIV risk behaviors, and (3) reduction in methamphetamine use. COVID-19 response: We developed a response plan for interruptions caused by COVID-19 lockdowns to ensure data quality and intervention fidelity.

Discussion: This study will provide important evidence for scale-up of EBIs for methamphetamine use among methadone patients in limited-resource settings. As the EBIs will be delivered by methadone providers, they can be readily implemented if the trial demonstrates effectiveness and cost-effectiveness.

Abstract:

In settings with a high burden of HIV, pregnant women often experience a cluster of risk factors, including alcohol use and intimate partner violence (IPV). These interrelated risks are poorly understood among pregnant women at risk of HIV in sub-Saharan Africa. We aim to determine cross-sectional associations between pregnant women’s alcohol use and victimization due to IPV in the HIV-Unexposed-Uninfected Mother-Infant Cohort Study in Cape Town, South Africa. Women who tested HIV-negative at first antenatal care (ANC) visit were followed to delivery. Trained interviewers collected demographic and psychosocial information, including recent alcohol use and experiences of IPV victimization. We assess the prevalence of alcohol use and associations with IPV using multivariable logistic regression. In 406 HIV-uninfected pregnant women (mean age = 28 years; mean gestational age = 21 weeks), 41 (10%) reported alcohol consumption in the past 12 months; 30/41 (73%) of these at hazardous levels. Any and hazardous alcohol use were associated with greater odds of reporting past year IPV (adjusted odds ratio [aOR] for hazardous use: 3.24, 95% CI = 1.11, 7.56; aOR for any alcohol use: 2.97, 95% CI = 1.19, 7.45). These data suggest the occurrence of overlapping HIV risk factors among pregnant women and may help design improved health interventions in this population.

Limited evidence for a moderating effect of HIV status on brain age in heavy episodic drinkers. Journal of neurovirology, 10.1007/s13365-022-01072-5. Advance online publication.

Abstract: 

We set out to test the hypothesis that greater brain ageing will be observed in people with HIV (PWH) and those who engage in heavy episodic drinking (HED), with their combined effects being especially detrimental in cognitive control brain networks. We correlated measures of “brain age gap” (BAG) and neurocognitive impairment in participants with and without HIV and HED. Sixty-nine participants were recruited from a community health centre in Cape Town: HIV – /HED – (N = 17), HIV + /HED – (N = 14), HIV – /HED + (N = 21), and HIV + /HED + (N = 17). Brain age was modelled using structural MRI features from the whole brain or one of six brain regions. Linear regression models were employed to identify differences in BAG between patient groups and controls. Associations between BAG and clinical data were tested using bivariate statistical methods. Compared to controls, greater global BAG was observed in heavy drinkers, both with (Cohen’s d = 1.52) and without (d = 1.61) HIV. Differences in BAG between HED participants and controls were observed for the cingulate and parietal cortex, as well as subcortically. A larger BAG was associated with higher total drinking scores but not nadir CD4 count or current HIV viral load. The association between heavy episodic drinking and BAG, independent of HIV status, points to the importance of screening for alcohol use disorders in primary care. The relatively large contribution of cognitive control brain regions to BAG highlights the utility of assessing the contribution of different brain regions to brain age.

Behavior change after fentanyl testing at a safe consumption space for women in Northern Mexico: A pilot study. The International journal on drug policy106, 103745. Advance online publication.

Abstract: 

Background: Fentanyl has led to an increased number of overdose deaths in North America. Testing substances for fentanyl may be a harm reduction strategy to prevent overdose. Little is known about behavior change after fentanyl testing and the attitudes around fentanyl knowledge and testing along the US-Mexico border in the context of a safe consumption site.

Methods: This was a pilot quantitative and qualitative study with 30 women who use drugs at an unsanctioned safe consumption site in Mexicali, Mexico. Women participated in a quantitative survey, a semi-structured interview, and fentanyl testing of substances. Injection behavior was observed after fentanyl testing results were provided. Qualitative data were collected to explore the meanings participants attributed to fentanyl and fentanyl testing.

Results: Half of the substances tested positive for fentanyl (n=15, 50%), and all of them were in samples of black tar heroin. Among those participants who tested positive for fentanyl, 7 (47%) subsequently used less of the intended substance, 1 did not use the intended substance, and 7 (47%) did not change their behavior (i.e., used as originally intended). In qualitative interviews, a predominant theme was a description of fentanyl as dangerous and deadly and fentanyl testing as being helpful for modifying drug use behaviors. However, participants recognized that there could be no change in behavior following a positive fentanyl test in the context of not being able to find substances free of fentanyl.

Conclusion: We observed mixed results related to behavior change after women’s intended substance for use tested positive for fentanyl. Fentanyl testing was acceptable to women, but behavior change was hampered by the inability to find substances free of fentanyl. Further research is needed to maximize the potential of fentanyl testing as a harm reduction tool especially in the context of a changing drug supply.

Abstract: 

Background: While there is significant research exploring adults’ use of opioids, there has been minimal focus on the opioid impact within emergency departments for the pediatric population.

Methods: We examined data from the Agency for Healthcare Research, the National Emergency Department Sample (NEDS), and death data from the Centers for Disease Control and Prevention. Sociodemographic and financial variables were analyzed for encounters during 2014-2017 for patients under age 18, matching diagnoses codes for opioid-related overdose or opioid use disorder.

Results: During this period, 59,658 children presented to an ED for any diagnoses involving opioids. The majority (68.5%) of visits were related to overdoses (poisoning), with a mean age of 11.3 years and a majority female (53%). There was a curvilinear relationship between age and encounters, with teens representing the majority of visits, followed by infants. The highest volume was seen in the Southern U.S., with over 58% more opioid visits than the next highest region (Midwest). Charges exceeded USD 157 million, representing 2% of total ED costs, with Medicaid responsible for 54% of the total.

Conclusions: With increases in substance use among children, there is a growing need for pediatric emergency physicians to recognize, refer, and initiate treatments.

Giang, L. M., Li, M. J., Okafor, C. N., Diep, N. B., & Shoptaw, S. J. (2022). Correlates of methamphetamine use severity among patients receiving methadone maintenance treatment for opioid use disorder in Vietnam. Journal of substance abuse treatment132, 108461.

Abstract:

Objectives: To assess the severity of methamphetamine use among methadone maintenance treatment (MMT) patients in Vietnam with opioid use disorder and concurrent methamphetamine use, and to identify risk factors associated with higher severity of methamphetamine use.

Methods: We used survey data and medical record abstractions from 428 people with opioid use disorder who also use methamphetamine while partaking in methadone treatment in five clinics in Hanoi, Vietnam. We used multinomial logistic regression to assess other risk factors and problems associated with high methamphetamine use severity.

Results: Those who reported injecting heroin in the past 3 months (AOR = 4.05, 95% CI [1.30, 12.55], p = 0.02), having a longer history of lifetime heroin use (AOR = 1.13, 95% CI [1.03, 1.24], p < 0.01), and having higher cravings (AOR = 1.97, 95% CI [1.31, 2.98], p < 0.01) and fatigue (AOR = 1.25, 95% CI [0.96, 1.61], p = 0.09) related to methamphetamine withdrawal had greater odds of high methamphetamine use severity. One of five clinics had a significantly higher percentage of methamphetamine use severity than others.

Conclusion: Successful MMT in patients with opioid use disorder in Vietnam may additionally require methamphetamine-focused screening and intervention.

H., Siminski, S., Javanbakht, M., & Gorbach, P. M. (2022). HIV, psychological resilience, and substance misuse during the COVID-19 pandemic: A multi-cohort study. Drug and alcohol dependence231, 109230.

Abstract:

Objective: The COVID-19 pandemic has dramatically impacted mental health, increasing rates of substance misuse. Resilience is a positive adaptation to stress that may act as a buffer against adverse mental health outcomes. Based on prior knowledge, we hypothesized that PLWH would display higher resilience than HIV-uninfected peers, and that high resilience would be associated with lower risk of substance misuse.

Methods: This analysis of the Collaborating Consortium of Cohorts Producing NIDA Opportunities (C3PNO) included data from six USA cohorts that administered a COVID-19-related survey with a 3-month follow-up during May 2020 and March 2021. All data was self-reported. The Brief Resilience Scale and General Anxiety Disorder-7 were utilized. Primary analyses consisted of multivariate generalized linear mixed models with random intercepts using binary logistic regression.

Results: A total of 1430 participants completed both surveys, of whom 670 (46.9%) were PLWH. PLWH had lower odds of anxiety (OR=0.67, 95% CI: 0.51-0.89) and higher odds of high resilience (OR=1.21, 95% CI: 1.02-1.44) than HIV-uninfected participants, adjusted for covariates. The presence of anxiety was associated with higher risk of misuse of all substances. High resilience was associated with lower risk of anxiety and misuse of substances, adjusted for covariates.

Conclusions: Psychological resilience was associated with lower risk of anxiety and substance misuse, potentially serving as a buffer against poor mental and behavioral health during the COVID-19 pandemic. Further research is needed to identify pathways of resilience in the context of substance misuse and comprehensive resilience-focused interventions.

Lake, M. T., Krishnamurti, T., Murtaugh, K. L., van Nunen, L. J., Stein, D. J., & Shoptaw, S. (2022). Decision-making tendencies and voucher spending independently support abstinence within contingency management for methamphetamine use disorder. Experimental and clinical psychopharmacology, 10.1037/pha0000574. Advance online publication.

Abstract: 

Decision-making tendencies and spending within cash voucher-based interventions have individually been shown to be related to future abstinence among participants with methamphetamine use disorder (MUD), but less is known of their independent contributions. This study of participants in a contingency management (CM) trial investigated whether decision-making and spending were each associated with future abstinence. Thirty-two outpatients with MUD, predominately male (68%) and mixed ancestry (94%) with a median age of 34 years, participated in an 8-week cash voucher-based CM pilot trial. Prior to commencing the trial, participants completed a computerized Iowa Gambling Task (IGT) to measure decision-making preferences for more frequent rewards and longer term gains of greater magnitude. Spending and abstinence of participants were tracked over the duration of the trial. In a secondary analysis, time-lagged counting process Cox Proportional Hazard models were conducted. Baseline decision-making, characterized by a preference for frequent rewards, was associated with a greater likelihood of future spending, Hazard Ratio; HR = 1.13 [1.06: 1.21]. Avoidance of short-term rewards to realize longer term, higher magnitude rewards, and spending at the prior visit were each associated with abstinence on the trial, HR = 1.12 [1.03: 1.22] and HR = 1.32 [1.08: 1.61], respectively. Controlling for decision-making, spending, and cumulative abstinence, prior abstinence remained the largest predictor of future abstinence, HR = 3.85 [2.88: 5.16]. Decision-making tendencies and spending are correlated yet independently associated with abstinence reinforcement in CM. Findings highlight the opportunity for behavioral treatment programs to tailor program structures to individual-specific characteristics.

Abstract: 

Objectives: Studies have shown that grit-defined as perseverance and passion for achieving one’s long-term goals-is associated with improved health outcomes, including lower levels of psychological distress. However, the psychometric properties of the original Grit Scale (Grit-O Scale) has not been validated among sexual minority men (SMM). The present study aimed to validate the Grit-O Scale among a sample of older SMM and assess the relationships between the Grit-O Scale factors and symptoms of psychological distress.

Method: We used data from a single visit of participants in the Multicenter AIDS Cohort Study (MACS) Healthy Aging longitudinal study. The sample included 981 older SMM (mean age = 61, SD = 8.5) with and without HIV. We conducted confirmatory factor analysis (CFA) to identify the two factors of the Grit-O Scale: consistency of interest and perseverance of effort. We also conducted a latent profile analysis (LPA) to identify distinct profiles of psychological distress from self-reported scales of depression, anxiety, and perceived stress.

Results: The Grit-O Scale showed acceptable reliability estimates for the items with Cronbach’s alpha reliability coefficients ranging from 0.77 to 0.82. The CFA identified the two factors of the Grit-O Scale with acceptable model fit (root mean square error of approximation = 0.058 [95% CI = 0.050, 0.067], comparative fit index = 0.95, Tucker-Lewis Index = 0.93, standardized root mean square residual = 0.07). The LPA yielded three mutually exclusive profiles of psychological distress (profile 1: low stress, anxiety, and depression; profile 2: high stress and depression and low anxiety; and profile 3: high stress, anxiety, and depression). In adjusted multinominal logistic regression analysis, we found that both higher levels of consistency of interest and perseverance of effort factors of the Grit-O Scale were significantly associated with decreased odds of being in profiles 2 and 3 compared with being in profile 1.

Conclusion: Our findings support the use of the Grit-O Scale among older SMM. Grit factors could explain variability in the negative psychological symptoms among older SMM and warrant further investigation.

Sexual Risk among Pregnant Women at Risk of HIV Infection in Cape Town, South Africa: What Does Alcohol Have to Do with It?. AIDS and behavior, 10.1007/s10461-022-03742-1. Advance online publication.

Abstract: 

This study examines baseline associations between alcohol use and HIV sexual risk among a cohort of HIV-uninfected pregnant women (n = 1201) residing in a high HIV burdened community in Cape Town, South Africa. Alcohol use was measured using a modified version of the Alcohol Use Disorder Identification Test (AUDIT). HIV sexual risk was measured through a composite variable of four risk factors: diagnosis with a STI, self-report of > 1 recent sex partners, partner HIV serostatus (unknown or HIV+) and condomless sex at last sex. Any past year alcohol use prior to pregnancy was reported by half of participants (50%); 6.0% reported alcohol use during pregnancy. Alcohol use prior to pregnancy was associated with increased odds of being at high risk of HIV (aOR = 1.33, 95% CI 1.05-1.68, for 2 risks and aOR = 1.47, 95% CI 0.95-2.27 for 3 risks). In addition to reducing alcohol use, several other strategies to address HIV sexual risk were identified. Evidence-based interventions to address alcohol use and other HIV sexual risk behaviors during pregnancy in South Africa are desperately needed. Qualitative work exploring individual and community level drivers of alcohol use among pregnant and breastfeeding women in this setting could support development of a culturally tailored intervention to address these issues in this population.

R., Pandya, A., Schackman, B. R., Shoptaw, S., Strathdee, S. A., Krebs, E., Nosyk, B., & Localized HIV Modeling Study Group (2022). Human Immunodeficiency Virus transmission by HIV Risk Group and Along the HIV Care Continuum: A Contrast of 6 US Cities. Journal of acquired immune deficiency syndromes (1999)89(2), 143–150.

Abstract: 

Background: Understanding the sources of HIV transmission provides a basis for prioritizing HIV prevention resources in specific geographic regions and populations. This study estimated the number, proportion, and rate of HIV transmissions attributable to individuals along the HIV care continuum within different HIV transmission risk groups in 6 US cities.

Methods: We used a dynamic, compartmental HIV transmission model that draws on racial behavior-specific or ethnic behavior-specific and risk behavior-specific linkage to HIV care and use of HIV prevention services from local, state, and national surveillance sources. We estimated the rate and number of HIV transmissions attributable to individuals in the stage of acute undiagnosed HIV, nonacute undiagnosed HIV, HIV diagnosed but antiretroviral therapy (ART) naïve, off ART, and on ART, stratified by HIV transmission group for the 2019 calendar year.

Results: Individuals with undiagnosed nonacute HIV infection accounted for the highest proportion of total transmissions in every city, ranging from 36.8% (26.7%-44.9%) in New York City to 64.9% (47.0%-71.6%) in Baltimore. Individuals who had discontinued ART contributed to the second highest percentage of total infections in 4 of 6 cities. Individuals with acute HIV had the highest transmission rate per 100 person-years, ranging from 76.4 (58.9-135.9) in Miami to 160.2 (85.7-302.8) in Baltimore.

Conclusion: These findings underline the importance of both early diagnosis and improved ART retention for ending the HIV epidemic in the United States. Differences in the sources of transmission across cities indicate that localized priority setting to effectively address diverse microepidemics at different stages of epidemic control is necessary.

Risk Behaviors Associated with Patterns of Sexualized Stimulant and Alcohol Use among Men Who Have Sex with Men: a Latent Class Analysis. Journal of urban health : bulletin of the New York Academy of Medicine99(2), 293–304.

Abstract: 

Substance use during sexual encounters (sexualized substance use) is an important driver of HIV and sexually transmitted infection (STI) disparities that are experienced by men who have sex with men (MSM). This analysis aimed to identify patterns of sexualized substance use and their associations with HIV risk behaviors. We utilized visit-level data from a longitudinal cohort of predominantly Black/Latinx MSM, half with HIV and half with substance use in Los Angeles, California. Every 6 months from 8/2014 to 3/2020, participants underwent STI testing and completed surveys on demographics, sexualized substance use (stimulant and/or alcohol intoxication during oral sex, receptive anal intercourse [RAI] and/or insertive anal intercourse [IAI]), transactional sex, biomedical HIV prevention (pre-/post-exposure prophylaxis use or undetectable viral load), and depressive symptoms. Latent class analysis was used to identify patterns of sexualized substance use. Multinomial logit models evaluated risk behaviors associated with latent classes. Among 2386 study visits from 540 participants, 5 classes were identified: no substance use, sexualized stimulant use, sexualized alcohol use, sexualized stimulant and alcohol use, and stimulant/alcohol use during oral sex and RAI. Compared to the no sexualized substance use class, sexualized stimulant use was associated with transactional sex, current diagnosis of STIs, not using HIV biomedical prevention, and depressive symptoms. Sexualized alcohol use had fewer associations with HIV risk behaviors. Patterns of sexual activities, and the substances that are used during those activities, confer different risk behavior profiles for HIV/STI transmission and demonstrate the potential utility of interventions that combine substance use treatment with HIV prevention.

Examining the Relative Contributions of Methamphetamine Use, Depression, and Sexual Risk Behavior on Rectal Gonorrhea/Chlamydia Among a Cohort of Men Who Have Sex With Men in Los Angeles, California. Sexually transmitted diseases49(3), 216–222.

Abstract: 

Background: Methamphetamine use, sexual risk behaviors, and depression contribute to ongoing human immunodeficiency virus (HIV) and sexually transmitted infection (STI) disparities among men who have sex with men (MSM). The relative contributions of these effects longitudinally are not well understood.

Methods: This analysis used visit-level data from a longitudinal cohort of MSM, half with HIV, in Los Angeles, CA. From August 2014 to March 2020, participants completed follow-up visits every 6 months and underwent testing for rectal gonorrhea/chlamydia (GC/CT) and completed questionnaires including depressive symptoms, number of receptive anal intercourse (RAI) partners, and methamphetamine use. Path analysis with structural equation modeling using concurrent and lagged covariates was used to identify relative contributions of methamphetamine use and depression on number of RAI partners and rectal GC/CT across time.

Results: Five hundred fifty-seven MSM with up to 6 visits (3 years) were included for a total of 2437 observations. Methamphetamine use and depressive symptoms were positively associated with number of RAI partners (β = 0.28, P < 0.001; β = 0.33, P = 0.018, respectively), which was positively associated with rectal GC/CT (β = 0.02, P < 0.001). When stratified by HIV status, depressive symptoms were positively associated with RAI partners for HIV-negative MSM (β = 0.50, P = 0.007) but were not associated for MSM living with HIV (β = 0.12, P = 0.57). Methamphetamine use was positively associated with RAI partners in both strata.

Conclusions: Factors and patterns, which contribute to risk behaviors associated with rectal GC/CT, may differ by HIV status. Our findings demonstrate the importance of combined treatment and prevention efforts that link screening and treatment of stimulant use and depression with STI prevention and treatment.

D., & Chander, G. (2022). The relationship of alcohol and other drug use during the COVID-19 pandemic among people with or at risk of HIV; A cross-sectional survey of people enrolled in Collaborating Consortium of Cohorts Producing NIDA Opportunities (C3PNO) cohorts. Drug and alcohol dependence, 109382. Advance online publication.

Abstract: 

Background: Alcohol use during the COVID-19 pandemic increased. People living with HIV or at risk for HIV acquisition often have psycho-social and structural barriers or co-occurring substance use making them vulnerable to the adverse effects of alcohol. We describe factors associated with alcohol use during the COVID-19 pandemic in this group.

Methods: From May 2020 to February 2021, 1984 people enrolled in 6 existing cohort studies completed surveys about alcohol and other drug use during the COVID-19 pandemic. We describe the past-month prevalence of no alcohol use, low-risk use, and hazardous use. We use multinomial regression to describe factors associated with low-risk or hazardous alcohol use relative to no alcohol use.

Results: Forty-five percent of participants reported no alcohol use, 33% low-risk use, and 22% hazardous use in the past 30 days. Cannabis and stimulant use were associated with a higher prevalence of low-risk use relative to no use. Tobacco, stimulant, cannabis use and recent overdose were associated with a higher prevalence of hazardous use relative to no use. Substance use treatment and living with HIV were associated with a lower prevalence of low-risk or hazardous use relative to no use.

Conclusions: Stimulant use was strongly associated with a higher prevalence of hazardous alcohol use while engagement in substance use treatment or living with HIV was associated with a lower prevalence. Ascertaining hazardous alcohol and other drug use, particularly stimulants, in clinical care could identify people at higher risk for adverse outcome and harm reduction counseling.

Examining the impact of social distancing and methamphetamine use on sexual risk and intimate partner violence in sexual and gender minority young adults during the COVID-19 pandemic. Drug and alcohol dependence232, 109231.

Abstract:

Background: During the COVID-19 pandemic in 2020, concerns were raised about the potential impact of pandemic-related social distancing measures on existing health disparities among sexual and gender minority (SGM) young adults, including HIV transmission risk and intimate partner violence (IPV). Another concern was the potential for increased methamphetamine use during the pandemic, which is a known risk factor for HIV transmission and IPV.

Methods: The present analysis examines the impact of COVID-19 social distancing (social distancing and quarantining) and methamphetamine use on HIV risk and IPV in a combined dataset from 3 cohort studies of SGM young adults (two in Los Angeles and one in Chicago) from May 2020 to April 2021 (n = 1142). Bivariate analyses and multivariable logistic regressions were estimated.

Results: The median age was 26. All participants were assigned male at birth and most participants were men (93.8%). The largest racial groups were Hispanic/Latinx (44.6%) and Black (29.0%). In adjusted models methamphetamine use was consistently associated with having a new sex partner, higher numbers of sex partners, and experience of IPV, during the pandemic. Reporting no social distancing and reporting one social distancing behavior, were associated with experience of IPV relative to reporting 2 social distancing behaviors. Social distancing was not associated with sexual risk behavior or Pre-exposure Prophylaxis use.

Conclusions: SGM young adults live at the intersection of multiple vulnerabilities during the COVID-19 pandemic. Addiction services, HIV prevention services, and violence support services should be prepared to support young adult SGM needs, particularly those who use methamphetamine.

Interruptions in Mental Health Care, Cannabis Use, Depression, and Anxiety during the COVID-19 Pandemic: Findings from a Cohort of HIV-Positive and HIV-Negative MSM in Los Angeles, California. Journal of urban health : bulletin of the New York Academy of Medicine99(2), 305–315.

Abstract:

The objective was to examine the impact of the COVID-19 pandemic on mental health care, cannabis use, and behaviors that increase the risk of STIs among men living with or at high risk for HIV. Data were from mSTUDY – a cohort of men who have sex with men in Los Angeles, California. Participants who were 18 to 45 years and a half were HIV-positive. mSTUDY started in 2014, and at baseline and semiannual visits, information was collected on substance use, mental health, and sexual behaviors. We analyzed data from 737 study visits from March 2020 through August 2021. Compared to visits prior to the COVID-19 pandemic, there were significant increases in depressive symptomatology (CES-D ≥ 16) and anxiety (GAD-7 ≥ 10). These increases were highest immediately following the start of the pandemic and reverted to pre-pandemic levels within 17 months. Interruptions in mental health care were associated with higher substance use (especially cannabis) for managing anxiety/depression related to the pandemic (50% vs. 31%; p-value < .01). Cannabis use for managing pandemic-related anxiety/depression was higher among those reporting changes in sexual activity (53% vs. 36%; p-value = 0.01) and was independently associated with having more than one sex partner in the prior 2 weeks (adjusted OR = 1.5; 95% CI 1.0-2.4). Our findings indicate increases in substance use, in particular cannabis, linked directly to experiences resulting from the COVID-19 pandemic and the associated interruptions in mental health care. Strategies that deliver services without direct client contact are essential for populations at high risk for negative sexual and mental health outcomes.

COVID-19 and the HIV continuum in people living with HIV enrolled in Collaborating Consortium of Cohorts Producing NIDA Opportunities (C3PNO) cohorts. Drug and alcohol dependence, 109355. Advance online publication.

Abstract: 

Background: The COVID-19 pandemic disrupted the normal delivery of HIV care, altered social support networks, and caused economic insecurity. People with HIV (PWH) are vulnerable to such disruptions, particularly if they have a history of substance use. We describe engagement in care and adherence to antiretroviral therapy (ART) for PWH during the pandemic.

Methods: From May 2020 to February 2021, 773 PWH enrolled in 6 existing cohorts completed 1495 surveys about substance use and engagement in HIV care during the COVID-19 pandemic. We described the prevalence and correlates of having missed a visit with an HIV provider in the past month and having missed a dose of ART in the past week.

Results: Thirteen percent of people missed an HIV visit in the past month. Missing a visit was associated with unstable housing, food insecurity, anxiety, low resiliency, disruptions to mental health care, and substance use including cigarette smoking, hazardous alcohol use, cocaine, and cannabis use. Nineteen percent of people reported missing at least one dose of ART in the week prior to their survey. Missing a dose of ART was associated with being a man, low resiliency, disruptions to mental health care, cigarette smoking, hazardous alcohol use, cocaine, and cannabis use, and experiencing disruptions to substance use treatment.

Conclusions: Social determinants of health, substance use, and disruptions to mental health and substance use treatment were associated with poorer engagement in HIV care. Close attention to continuity of care during times of social disruption is especially critical for PWH.

M., Mustanski, B., Javanbakht, M., Siminski, S., & Genberg, B. L. (2022). Factors associated with self-reported avoidance of harm reduction services during the COVID-19 pandemic by people who use drugs in five cities in the United States and Canada. Drug and alcohol dependence, 109544. Advance online publication.

Abstract:

Background: This study examines individual-level factors associated with avoiding two important health services for people who use drugs-medications for treatment of opioid use disorder and syringe service programs-during the first year of the COVID-19 pandemic.

Methods: Data come from two subsamples of people who use drugs who were active participants in one of nine cohort studies in Vancouver, British Columbia; Baltimore, Maryland; Los Angeles, California; Chicago, Illinois; and Miami, Florida. Participants were interviewed remotely about COVID-19-associated disruptions to healthcare. We estimated the association of demographic, social, and health factors with each outcome using logistic regression among 702 participants (medication analysis) and 304 participants (syringe service analysis.) Analyses were repeated, stratified by city of residence, to examine geographic variation in risk.

Results: There were large differences between cities in the prevalence of avoiding picking up medications for opioid use disorder, with almost no avoidance in Vancouver (3%) and nearly universal avoidance in Los Angeles, Chicago, and Miami (>90%). After accounting for between-city differences, no individual factors were associated with avoiding picking up medications. The only factor significantly associated with avoiding syringe service programs was higher levels of self-reported worry about COVID-19.

Conclusion: During the first year of the COVID-19 pandemic, geographic differences in service and policy contexts likely influenced avoidance of health and harm reduction services by people who use drugs in the United States and Canada more than individual differences between people.

Implementation of Client-Centered Care Coordination for HIV Prevention with Black Men Who Have Sex with Men: Activities, Personnel Costs, and Outcomes-HPTN 073. Journal of racial and ethnic health disparities, 10.1007/s40615-021-01209-y. Advance online publication.

Abstract:

Background: Black men who have sex with men (MSM) experience disproportionate rates of HIV infection in the USA, despite being no more likely to engage in sexual risk behaviors than other MSM racial/ethnic groups. HIV pre-exposure prophylaxis (PrEP) has been shown to reduce risk of HIV acquisition; however, rates of PrEP use among Black MSM remain low. Clinical, psychosocial, and structural factors have been shown to impact PrEP use and adherence among Black MSM. Care coordination of HIV prevention services has the potential to improve PrEP use and adherence for Black MSM, as it has been shown to improve HIV-related care outcomes among people living with HIV.

Methods: Client-centered care coordination (C4) is a multi-level intervention designed to address clinical, psychosocial, and structural barriers to HIV prevention services for Black MSM within HPTN 073, a PrEP demonstration project among Black MSM in three cities in the USA. The current study examined the implementation process of C4, specifically investigating the activities, cost, time, and outcomes associated with the C4 intervention.

Results: On average, participants engaged in five care coordination encounters. The vast majority of care coordination activities were conducted by counselors, averaging 30 min per encounter. The cost of care coordination was relatively low with a mean cost of $8.70 per client encounter.

Conclusion: Although client-centered care coordination was initially implemented in well-resourced communities with robust HIV research and service infrastructure, our findings suggest that C4 can be successfully implemented in resource constrained communities.

Decision-Making at the Intersection of Risk and Pleasure: A Qualitative Inquiry with Trans Women Engaged in Sex Work in Lima, Peru. AIDS and behavior26(3), 843–852.

Abstract:

To inform culturally relevant HIV prevention interventions, we explore the complexity of sex work among Peruvian transgender women. In 2015, we conducted twenty in-depth interviews and demographic surveys with transgender women in Lima, Peru to examine how transgender women enact individual- and community-level resistance strategies within a context of pervasive marginalization. Although 40% self-identified as “sex workers,” 70% recently exchanged sex for money. Participants described nuanced risk-benefit analyses surrounding paid sexual encounters. Classification of clients as “risky” or “rewarding” incorporated issues of health, violence, and pleasure. Interviews highlighted context-informed decision-making (rejecting disrespectful clients, asserting condom use with specific partner types) demonstrating that motivations were not limited to HIV prevention or economic renumeration, but considered safety, health, attraction, gender validation, hygiene, and convenience. These findings underscore the complex risk assessments employed by Peruvian trans women. These individual-level decision-making and context-specific health promotion strategies represent critical frameworks for HIV prevention efforts.

Anal cytology screening in men who have sex with men with HIV at a university hospital in Bogotá, Colombia. International journal of STD & AIDS33(7), 701–708.

Abstract:

Background: Risk of anal squamous cell carcinoma (anal cancer) is greater among men who have sex with men (MSM) living with human immunodeficiency virus (HIV). We describe the frequency of and factors associated with abnormal anal cytology results in Colombian MSM living with HIV.

Methods: This retrospective observational cohort study included MSM ≥18 years old living with HIV screened with anal cytology at Hospital Universitario San Ignacio in Bogotá, Colombia between January 2019 and February 2020. A multivariable log-binomial regression model estimated associations with abnormal anal cytology.

Results: A total of 211 patients were included. Mean age was 35.6 years. Sixty-eight (32.3%) had an abnormal anal cytology result: ASC-US 33.8% (n = 23); LSIL 60.3% (n = 41); and HSIL 5.9% (n = 4). MSM with an STI diagnosis in the previous 12 months (RR 1.48, [95% CI 1.03-2.12], p = 0.032) or with a CD4+ T cell count <200 (RR 2.08 [95% CI 1.16-3.73], p = 0.014) were significantly more likely to have abnormal anal cytology.

Conclusions: These data provide crucial information to guide scale up of anal cancer screening at select centers in Colombia. Our results also suggest STI prevention efforts and improved virological control among MSM living with HIV may have the secondary benefit of reducing the risk of anal cancer.

Multilevel Analysis of Individual and Neighborhood Characteristics Associated with Viral Suppression Among Adults with HIV in Rio de Janeiro, Brazil. AIDS and behavior26(3), 947–962.

Abstract: 

Understanding the impact of neighborhood context on viral suppression outcomes may help explain health disparities and identify future interventions. We assessed the relationship between individual characteristics, neighborhood socioeconomic context, and viral suppression using multilevel logistic regression models. Adults with HIV initiating antiretroviral therapy (ART) between 2000 and 2017, who resided in Rio de Janeiro and had an HIV-1 RNA level (viral load) measured 90-270 days after ART initiation were included. Overall, 83.9% achieved viral suppression. Participants who were older, had a higher level of education, and identified as heterosexual cisgender men and cisgender men-who-have-sex-with-men had increased odds of viral suppression. Later calendar year of ART initiation carried the strongest association with viral suppression, reflecting the increased effectiveness and tolerability of ART over time. Neighborhood socioeconomic indicators did not predict viral suppression in unadjusted or adjusted analyses, which may result from the integrated care provided in our health care facility together with Brazil’s universal treatment.

Exploring Contextual Differences for Sexual Role Strain Among Transgender Women and Men Who Have Sex with Men in Lima, Peru. Archives of sexual behavior51(4), 1977–1991.

Abstract:

Sexual and gender politics inform relational expectations surrounding sexual experiences of Peruvian transgender women (TW) and men who have sex with men (MSM). We used the framework of sexual role strain, or incongruence between preferred sexual role and actual sexual practices, to explore potential conflicts between personally articulated identities and externally defined norms of gender and sexuality and its potential to increase HIV/STI risk. Cross-sectional individual- and dyad-level data from 766 TW and MSM in Lima, Peru were used to assess the partnership contexts within which insertive anal intercourse was practiced despite receptive role preference (receptive role strain), and receptive anal intercourse practiced despite insertive role preference (insertive role strain). Sexual role strain for TW was more common with non-primary partners, while for MSM it occurred more frequently in the context of a primary partnership. Receptive role strain was more prevalent for TW with unknown HIV status (reference: without HIV) or pre-sex drug use (reference: no pre-sex drug use). For homosexual MSM, receptive role strain was more prevalent during condomless anal intercourse (reference: condom-protected) and with receptive or versatile partners (reference: insertive). Among heterosexual or bisexual MSM, insertive role strain was more prevalent with insertive or versatile partners (reference: receptive), and less prevalent with casual partners (reference: primary). Our findings suggest TW and MSM experience different vulnerabilities during sexual role negotiation with different partner-types. Future studies should explore the impact of sexual role strain on condom use agency, HIV/STI risk, and discordances between public and private presentations of gender and sexual orientation.

Pre-exposure prophylaxis use, HIV knowledge, and internalized homonegativity among men who have sex with men in Brazil: A cross-sectional study. Lancet Regional Health. Americas6, 100152.

Abstract: 

Background: Pre-exposure prophylaxis (PrEP) use in Brazil remains low despite free national access. We explored associations of HIV knowledge and internalized homonegativity with PrEP use among PrEP-eligible men who have sex with men (MSM).

Methods: Brazilian Hornet users completed an online, cross-sectional survey in February-March 2020. We included cis-men ≥18 years old who reported recent sex with men and were PrEP-eligible per the following: condomless anal intercourse, partner(s) living with HIV, transactional sex, and/or sexually transmitted infection. Our outcome was current PrEP use, defined by the response, “I am currently taking PrEP.” Key predictors included the HIV/AIDS Knowledge Assessment (HIV-KA) and Reactions to Homosexuality Scale (RHS); higher scores indicate greater knowledge and greater internalized homonegativity, respectively. Scales were standardized for analysis. Associations with current PrEP use were estimated using adjusted odds ratios (aOR) with 95% confidence intervals (95%CI).

Findings: Among 2398 PrEP-eligible MSM, n = 370 (15·4%) reported current PrEP use. Increasing HIV-KA scores were associated with greater odds of PrEP use (aOR 1·70 [95%CI 1·41-2·04], p < 0·001), and increasing RHS scores with lower odds of PrEP use (aOR 0·83 [95%CI 0·73-0·96], p = 0·010). PrEP use was lower among 18-24 versus 40+-years-old MSM (aOR 0·43 [95%CI 0·27-0·69], p = 0·005), and in Black versus White/Asian respondents (aOR 0·51 [95%CI 0·31-0·85], p = 0·040).

Interpretation: Among PrEP-eligible Brazilian MSM, HIV knowledge was associated with increased PrEP use and internalized homonegativity with decreased use. Wider dissemination of HIV prevention knowledge and addressing stigma experienced by MSM could promote increased PrEP use.

Baricitinib versus dexamethasone for adults hospitalised with COVID-19 (ACTT-4): a randomised, double-blind, double placebo-controlled trial. The Lancet. Respiratory medicine10(9), 888–899.

Abstract:

Background: Baricitinib and dexamethasone have randomised trials supporting their use for the treatment of patients with COVID-19. We assessed the combination of baricitinib plus remdesivir versus dexamethasone plus remdesivir in preventing progression to mechanical ventilation or death in hospitalised patients with COVID-19.

Methods: In this randomised, double-blind, double placebo-controlled trial, patients were enrolled at 67 trial sites in the USA (60 sites), South Korea (two sites), Mexico (two sites), Singapore (two sites), and Japan (one site). Hospitalised adults (≥18 years) with COVID-19 who required supplemental oxygen administered by low-flow (≤15 L/min), high-flow (>15 L/min), or non-invasive mechanical ventilation modalities who met the study eligibility criteria (male or non-pregnant female adults ≥18 years old with laboratory-confirmed SARS-CoV-2 infection) were enrolled in the study. Patients were randomly assigned (1:1) to receive either baricitinib, remdesivir, and placebo, or dexamethasone, remdesivir, and placebo using a permuted block design. Randomisation was stratified by study site and baseline ordinal score at enrolment. All patients received remdesivir (≤10 days) and either baricitinib (or matching oral placebo) for a maximum of 14 days or dexamethasone (or matching intravenous placebo) for a maximum of 10 days. The primary outcome was the difference in mechanical ventilation-free survival by day 29 between the two treatment groups in the modified intention-to-treat population. Safety analyses were done in the as-treated population, comprising all participants who received one dose of the study drug. The trial is registered with ClinicalTrials.gov, NCT04640168.

Findings: Between Dec 1, 2020, and April 13, 2021, 1047 patients were assessed for eligibility. 1010 patients were enrolled and randomly assigned, 516 (51%) to baricitinib plus remdesivir plus placebo and 494 (49%) to dexamethasone plus remdesivir plus placebo. The mean age of the patients was 58·3 years (SD 14·0) and 590 (58%) of 1010 patients were male. 588 (58%) of 1010 patients were White, 188 (19%) were Black, 70 (7%) were Asian, and 18 (2%) were American Indian or Alaska Native. 347 (34%) of 1010 patients were Hispanic or Latino. Mechanical ventilation-free survival by day 29 was similar between the study groups (Kaplan-Meier estimates of 87·0% [95% CI 83·7 to 89·6] in the baricitinib plus remdesivir plus placebo group and 87·6% [84·2 to 90·3] in the dexamethasone plus remdesivir plus placebo group; risk difference 0·6 [95% CI -3·6 to 4·8]; p=0·91). The odds ratio for improved status in the dexamethasone plus remdesivir plus placebo group compared with the baricitinib plus remdesivir plus placebo group was 1·01 (95% CI 0·80 to 1·27). At least one adverse event occurred in 149 (30%) of 503 patients in the baricitinib plus remdesivir plus placebo group and 179 (37%) of 482 patients in the dexamethasone plus remdesivir plus placebo group (risk difference 7·5% [1·6 to 13·3]; p=0·014). 21 (4%) of 503 patients in the baricitinib plus remdesivir plus placebo group had at least one treatment-related adverse event versus 49 (10%) of 482 patients in the dexamethasone plus remdesivir plus placebo group (risk difference 6·0% [2·8 to 9·3]; p=0·00041). Severe or life-threatening grade 3 or 4 adverse events occurred in 143 (28%) of 503 patients in the baricitinib plus remdesivir plus placebo group and 174 (36%) of 482 patients in the dexamethasone plus remdesivir plus placebo group (risk difference 7·7% [1·8 to 13·4]; p=0·012).

Interpretation: In hospitalised patients with COVID-19 requiring supplemental oxygen by low-flow, high-flow, or non-invasive ventilation, baricitinib plus remdesivir and dexamethasone plus remdesivir resulted in similar mechanical ventilation-free survival by day 29, but dexamethasone was associated with significantly more adverse events, treatment-related adverse events, and severe or life-threatening adverse events. A more individually tailored choice of immunomodulation now appears possible, where side-effect profile, ease of administration, cost, and patient comorbidities can all be considered.

HIV Treatment Adherence Strategies Among Virally Suppressed Black Sexual Minority Men in Baltimore, Maryland, and Los Angeles, California: A Theory-Based Qualitative Study. The Journal of the Association of Nurses in AIDS Care : JANAC33(1), 54–62.

Abstract:

The goals and strategies of Black sexual minority men living with HIV (BSMMLWH) who achieve viral suppression require further investigation. This study explored treatment adherence strategies among BSMMLWH with sustained viral suppression. We conducted 27 in-depth qualitative interviews with BSMMLWH in Baltimore, Maryland, and Los Angeles, California, between December 2018 and May 2019. Interviews included questions guided by Positive Deviance and Life Course theoretical frameworks regarding multilevel factors and explicit strategies for antiretroviral therapy adherence. Themes regarding intentional, age group-specific strategies such as using technology (among younger men) and taking HIV medications with other daily pills (among older men) were identified. Participants also reported symbiotic goals and values that encouraged adherence, such as having a desire to live, strong familial relationships with clinicians, and support networks. Identifying personal goals and having supportive clinical and social relationships could be key to improving treatment adherence and viral suppression among BSMMLWH.

Abstract: 

Background: Preliminary evidence indicates that acute and chronic psychological stress affect sexual arousal and satisfaction. African American women, in particular, are vulnerable to the impacts of gender- and race-related stress, given their socially constructed identities as African Americans and as women.

Aim: We examined associations between minority stress and sexual function using data from 248 African American women.

Methods: Surveys were conducted with 248 African American women in South LA with male partners at risk for acquiring HIV. We analyzed self-reports on (i) stress indicators: chronic burden, perceived racism/sexism, and histories of trauma/sexual abuse; (ii) Female Sexual Function Index domains: desire, arousal, and satisfaction; and (iii) potential moderators: social support and spirituality. We used multiple regression, adjusting for potential confounding factors, to examine the relationships between stress indictors, potential moderators, and sexual function domains.

Outcomes: The outcomes were the female sexual function index domains of desire, arousal, and satisfaction.

Results: This largely low-income sample experienced significant chronic and acute stressors, was highly spiritual and reported strong social support. Moderate-high chronic burden and increasing sexism scores were independently associated with decreased arousal (B = -0.38, 95%CI = -0.75, -0.02) and satisfaction (B = -0.03, 95%CI = -0.06, 0.00) scores, respectively.

Clinical implications: Providers may want to explore chronic burden in patients who complain about low sexual arousal. Additionally, to develop effective HIV- and other STI-related interventions that impact behaviors that can confer sexual risk, prevention strategies are needed that either reduce contextual stressors or mitigate their impact.

Strengths: Strengths of this research are that it focuses on sexual function among previously under-studied, low-income African American women and that it takes into account the unique set of stressors faced by these women.

Limitations: A limitation is that the sample size may have been too small to capture the effects of potential moderators.

Conclusions: Low-income African American women accumulate life stressors that may harm sexual function. Schrode K, Poareo E, Li M, et al. Minority Stress and Sexual Functioning Among African American Women With At-Risk Partners in South Los Angeles. J Sex Med 2022;19:603-612.

Acceptability and Appropriateness of Digital PrEP Interventions for Black and Latina Cisgender Women: Perspectives From Service Providers in Los Angeles County. Journal of acquired immune deficiency syndromes (1999)90(S1), S134–S140.

Abstract:

Background: Black and Latina cisgender women (BLCW) experience disproportionately high rates of HIV infection compared with White women. BLCW also experience disparities in uptake of pre-exposure prophylaxis (PrEP), a highly effective HIV prevention strategy. Digital technology interventions may help to improve PrEP accessibility among BLCW and address barriers to receiving PrEP services in clinical settings.

Methods: We conducted a formative implementation research project with service providers to explore the use of digital technology interventions to improve PrEP care continuum outcomes among priority populations in Los Angeles County. A thematic analysis approach was then used to assess the perceived acceptability and appropriateness of digital PrEP interventions for BLCW.

Results: Of the five technology products presented, service providers viewed the stand-alone telemedicine platforms as the most acceptable intervention type for BLCW. Service providers also noted perceived benefits and barriers that BLCW may experience in using stand-alone telemedicine platforms, and offered recommendations for tailoring the products to meet the individual needs of BLCW.

Conclusions: Digital PrEP interventions may help address barriers BLCW experience in accessing PrEP in clinical settings. We offer suggestions of implementation strategies to optimize the use of digital PrEP interventions among BLCW.

Abstract:

Persons living with HIV (PLWH) with socio-economic vulnerabilities are especially vulnerable to HIV stigma and adverse HIV outcomes. Stigma related to HIV may intersect with marginalized socio-economic conditions to negatively affect social networks. HIV stigma may limit the ability of individuals to sustain social relationships. This study examined the potential cross-sectional and longitudinal associations between HIV stigma and the quality and quantity of social networks for PLWH. PLWH (n = 1,082) who were experiencing housing, employment, and medical care-related difficulties were recruited to participate in a one-year navigation and system coordination intervention to improve housing stability and employment. Neither stigma reduction nor social networks were the main components of the intervention. A series of latent growth curves were estimated to assess the cross-sectional and longitudinal relationships among internalized and anticipated HIV stigma and social networks. Anticipated HIV stigma predicted social networks both cross-sectionally and longitudinally. Internalized HIV stigma predicted social networks cross-sectionally but not longitudinally in this population. These data support the HIV Stigma Framework and suggest that anticipated stigma seems to have a strong association with social networks. As anticipated stigma decreases over time, social network scores increase. Interventions to decrease anticipated HIV stigma as a mechanism of improving social networks warrants further investigation.

US public charge policy and Latinx immigrants’ thoughts about health and healthcare utilization. Ethnicity & health, 1–18. Advance online publication.

Abstract:

Objectives: We examined Latinx immigrants’ perceptions of US policy related to restrictions on immigrants’ use of public resources and their thoughts about the influence of these on immigrants’ healthcare utilization.

Design: A series of 16 focus group discussions with Latinx immigrant men and women (documented and undocumented) (N = 130) were conducted between May and July 2017 across four US cities.

Results: Four central themes emerged: participants attributed the limited resources available for affordable healthcare for many uninsured US immigrants (both documented and undocumented) to the US government’s view of immigrants as burdens on public resources and its subsequent unwillingness to dedicate funds for their care; participants expressed concerns, some unfounded, about negative immigration ramifications arising from diagnosis with health conditions perceived to be serious and/or expensive to treat; participants noted that some immigrants avoided using health programs and services to which they were entitled because of immigration concerns; finally, participants described how access to information on immigration laws and healthcare resources, and conversely, misinformation about these, influenced healthcare utilization.

Conclusions: Participants were acutely aware of the image of immigrants as public charges or potential burdens on government resources that underlies US immigration policy. In some cases, participants came to inaccurate and potentially harmful conclusions about the substance of laws and regulations based on their beliefs about the government’s rejection of immigrants who may burden public resources. This underscores the importance of ensuring that immigrants have access to information on immigration-related laws and regulations and on healthcare resources available to them. Participants noted that access to information also fostered resilience to widespread misinformation. Importantly, however, participants’ beliefs had some basis in US immigration policy discourse. Law and policy makers should reconsider legislation and political commentary that frame self-reliance, the guiding principle of US immigration policy, in terms of immigrants’ use of publicly funded healthcare resources.

Abstract:

Background: HIV infections disproportionately impact Latino gay and bisexual men (GBM) in the United States. Pre-Exposure Prophylaxis (PrEP) is a proven prevention strategy that can help reduce new HIV infections in this population. Unfortunately, PrEP adoption and persistence among Latino GBM remain low. The added benefits of using PrEP experienced by Latino GBM can provide important insights to inform the development of PrEP messaging to motivate this population to explore and consider PrEP as an appropriate and acceptable HIV prevention tool.

Methods: We conducted in-depth interviews with Latino GBM PrEP users to explore positive feelings and emotions, and additional benefits gained from using PrEP. Data were analyzed using thematic analysis.

Results: A total of 29 Latino GBM completed the study interview. The average age of participants was 30 years, and the mean length of time using PrEP was 17.1 months. Five themes were constructed from the data representing the additional benefits gained by Latino GBM PrEP users, and included: (1) reduced fear, anxiety, and stress about HIV, HIV testing, and sex; (2) feeling empowered and in control of their HIV risk; (3) greater awareness of sexual risk behaviors and sexual health; (4) greater sexual exploration and pleasure, and comfort having condomless sex; and (5) a greater connection to community and a feeling of contributing to the elimination of HIV.

Conclusions: The added benefits identified in this study represent a range of social, emotional, and psychological benefits that Latino GBM experience while using PrEP. They speak to the complementary benefits that PrEP can bring to Latino GBM who decide to use the medication, that go beyond HIV prevention. These findings can inform the development of future PrEP messaging to help improve motivation for PrEP uptake and persistent use among Latino GBM.

HIV Disclosure Practices to Family among Mexican and Puerto Rican Sexual Minority Men with HIV in the Continental USA: Intersections of Sexual Orientation and HIV Stigma. Journal of homosexuality, 1–25. Advance online publication.

Abstract:

Disclosing a seropositive HIV status still is a complex process of assessing the risks, benefits, and potential personal and interpersonal outcomes associated with disclosure, such as stigma, rejection, or emotional support. We examined HIV disclosure practices to family and intersectional stigma related to HIV and sexual orientation among Latino sexual minority men (LSMM) of Mexican and Puerto Rican origin with HIV in the continental USA. Guided by Framework Analysis, we present data from 54 interviews with 33 LSMM participants in HIV care engagement interventions, and 21 project staff implementing the interventions. LSMM disclosed their HIV status to family seeking support. They applied stigma management techniques to manage the information communicated to family about their HIV status, including selective disclosure to some family members, conveying strategic information about the significance of having HIV, non-disclosure, or partial disclosure, silence and deceptions. LSMM HIV disclosure practices to family encompassed appraisals of intersectional stigma related to their sexual orientation and HIV, assessing the potential outcomes of disclosure, and the preservation of family ties.

Galvan, F. H., Liu, H., Brooks, R. A., Chen, Y. T., & Mendoza Lepe, R. (2022). Using social and sexual networking mobile applications to promote HIV testing, medical care and prevention services among Latino men who have sex with men in Los Angeles County, California, USA. PloS one17(5), e0268406.

Abstract:

HIV disproportionately affects Latinos versus Whites, with Latinos having higher rates of HIV. Additionally, many HIV-positive Latinos are unaware of their infection. Proyecto Protégete, an HIV prevention intervention developed for Latino men who have sex with men (MSM), used social and sexual networking mobile applications (apps) to recruit individuals for HIV testing and linkage to medical care and prevention services. This study occurred in Los Angeles County, California, USA from December 18, 2015 to April 22, 2017. The study’s primary aim was to assess Proyecto Protégete’s ability to successfully recruit Latino MSM involved in high-risk sexual activities. A secondary aim was to evaluate its capacity to promote HIV testing and linkage to HIV medical care and prevention services among this population by comparing it to two programs with similar samples. Comparisons using Fisher’s Exact Test were conducted between Proyecto Protégete and the HIV testing program of the agency in which Proyecto Protégete was located and the County-funded HIV testing programs to compare the samples’ rates of HIV-positive Latino MSM identified through HIV testing and linked to HIV medical care and prevention services. Participants were recruited through seven apps. In Proyecto Protégete, 9,573 individuals completed the screener, 4,657 were eligible, and 359 (7.7% of those eligible) enrolled. Among those enrolled, 79% reported anal sex without a condom in the previous twelve months; 51% reported anal sex under the influence of alcohol. The HIV positivity rates were as follows: Proyecto Protégete, 1.71%; the agency, 1.25% (p = .293, compared to Proyecto Protégete); and the County, 1.09% (p = .172, compared to Proyecto Protégete). The rates of those confirmed as new HIV-positives and linked to medical care within 30 days were as follows: Proyecto Protégete, 71.4%; the agency, 81.5% (p = .450, compared to Proyecto Protégete); and the County, 77.3% (p = .503, compared to Proyecto Protégete). Proyecto Protégete had a higher rate of linked referrals to prevention services than the agency’s testing program (19.5% versus 8.3%, p < .001). Proyecto Protégete experienced successes in some areas but not in others. Future research should build on Proyecto Protégete’s experiences to promote HIV-related services among Latino MSM.

Friedman, J., Montero, F., Bourgois, P., Wahbi, R., Dye, D., Goodman-Meza, D., & Shover, C. (2022). Xylazine spreads across the US: A growing component of the increasingly synthetic and polysubstance overdose crisis. Drug and alcohol dependence233, 109380.

Abstract: 

Background: Sharp exacerbations of the US overdose crisis are linked to polysubstance use of synthetic compounds. Xylazine is a veterinary tranquilizer, long noted in the street opioid supply of Puerto Rico, and more recently Philadelphia. Yet its national trends, geographic distribution, and health risks are poorly characterized.

Methods: In this sequential mixed-methods study, xylazine was increasingly observed by ethnographers in Philadelphia among drug-sellers and people who inject drugs (PWID). Subsequently, we systematically searched for records describing xylazine-present overdose mortality across the US and assessed time trends and overlap with other drugs.

Results: In 10 jurisdictions – representing all four US Census Regions – xylazine was increasingly present in overdose deaths, rising from 0.36% of deaths in 015m 6.7% in 2020. The highest xylazine prevalence data was observed in Philadelphia, (25.8% of deaths), followed by Maryland (19.3%) and Connecticut (10.2%). Illicitly-manufactured-fentanyls were present in 98.4% of xylazine-present-overdose-deaths – suggesting a strong ecological link – as well as cocaine (45.4%), benzodiazepines (28.4%), heroin (23.3%), and alcohol (19.7%). PWID in Philadelphia described xylazine as a sought-after adulterant that lengthens the short duration of fentanyl injections. They also linked it to increased risk of soft tissue infection and naloxone-resistant overdose.

Conclusions: Xylazine is increasingly present in overdose deaths, linked to the proliferation of illicitly-manufactured-fentanyls. Ethnographic accounts associate it with profound risks for PWID. Nevertheless, many jurisdictions do not routinely test for xylazine, and it is not comprehensively tracked nationally. Further efforts are needed to provide PWID with services that can help minimize additional risks associated with a shifting drug supply.

Abstract: 

Objectives: To investigate the impact of the COVID-19 pandemic along the U.S.-Mexico border region and evaluate the relationship of COVID-19 related mortality, socioeconomic status, and vaccination.

Methods: We used indirect standardization to age-adjust mortality rates and calculate standardized mortality ratios [SMR] in both countries. To examine the impact of socioeconomic factors, we calculated the Human Development Index (HDI) by county/municipality. We performed linear regression to understand the relationship between mortality, vaccination, and HDI. We used choropleth maps to visualize the trends seen in the region.

Results: Between January 22nd, 2020 and December 1st, 2021, surges of cases and deaths were similar in dyad cities along the U.S.-Mexico border visualizing the interconnectedness of the region. Mortality was higher in U.S. counties along the border compared to the national average (SMR 1.17, 95% CI 1.15-1.19). In Mexico, border counties had a slightly lower mortality to the national average (SMR 0.94, 95% CI 0.93-0.95). In U.S. border states, SMR was shown to negatively correlate with human development index (HDI), a socioeconomic proxy, resulting in a higher SMR in the border region compared to the rest of the counties. Conversely in Mexican border states, there was no association between SMR and HDI. Related to vaccination, U.S. counties along the border were vaccinated at a greater percentage than non-border counties and vaccination was negatively correlated with HDI. In Mexico, states along the border had a higher ratio of vaccinations per person than non-border states.

Conclusions: The U.S.-Mexico border is a divide of incredible importance not only to immigration but as a region with unique social, economic, environmental, and epidemiological factors that impact disease transmission. We investigated how the COVID-19 pandemic followed trends of previously studied diseases in the corridor such as tuberculosis, HIV, and influenza H1N1. These data state how targeted intervention along the U.S.-Mexico border region is a necessity when confronting COVID-19 and have implications for future control of infectious diseases in the region.

Abstract:

Importance: Overdose is one of the leading causes of death in the US; however, surveillance data lag considerably from medical examiner determination of the death to reporting in national surveillance reports.

Objective: To automate the classification of deaths related to substances in medical examiner data using natural language processing (NLP) and machine learning (ML).

Design, setting, and participants: Diagnostic study comparing different natural language processing and machine learning algorithms to identify substances related to overdose in 10 health jurisdictions in the US from January 1, 2020, to December 31, 2020. Unstructured text from 35 433 medical examiner and coroners’ death records was examined.

Exposures: Text from each case was manually classified to a substance that was related to the death. Three feature representation methods were used and compared: text frequency-inverse document frequency (TF-IDF), global vectors for word representations (GloVe), and concept unique identifier (CUI) embeddings. Several ML algorithms were trained and best models were selected based on F-scores. The best models were tested on a hold-out test set and results were reported with 95% CIs.

Main outcomes and measures: Text data from death certificates were classified as any opioid, fentanyl, alcohol, cocaine, methamphetamine, heroin, prescription opioid, and an aggregate of other substances. Diagnostic metrics and 95% CIs were calculated for each combination of feature extraction method and machine learning classifier.

Results: Of 35 433 death records analyzed (decedent median age, 58 years [IQR, 41-72 years]; 24 449 [69%] were male), the most common substances related to deaths included any opioid (5739 [16%]), fentanyl (4758 [13%]), alcohol (2866 [8%]), cocaine (2247 [6%]), methamphetamine (1876 [5%]), heroin (1613 [5%]), prescription opioids (1197 [3%]), and any benzodiazepine (1076 [3%]). The CUI embeddings had similar or better diagnostic metrics compared with word embeddings and TF-IDF for all substances except alcohol. ML classifiers had perfect or near perfect performance in classifying deaths related to any opioids, heroin, fentanyl, prescription opioids, methamphetamine, cocaine, and alcohol. Classification of benzodiazepines was suboptimal using all 3 feature extraction methods.

Conclusions and relevance: In this diagnostic study, NLP/ML algorithms demonstrated excellent diagnostic performance at classifying substances related to overdoses. These algorithms should be integrated into workflows to decrease the lag time in reporting overdose surveillance data.

Abstract: 

Healthcare workers (HCWs) from minoritized communities are a critical partner in moving vaccine-hesitant populations toward vaccination, yet a significant number of these HCWs are delaying or deciding against their own COVID-19 vaccinations. Our study aims to provide a more nuanced understanding of vaccine hesitancy among racially and ethnically minoritized HCWs and to describe factors associated with vaccine non-acceptance. Analysis of a sub-sample of racially and ethnically minoritized HCWs (N = 1131), who participated in a cross-sectional study at two large Southern California medical centers, was conducted. Participants completed an online survey consisting of demographics, work setting and clinical role, influenza vaccination history, COVID-19 knowledge, beliefs, personal COVID-19 exposure, diagnosis, and impact on those closest to them. While overall most HCWs were vaccinated (84%), 28% of Black, 19% of Hispanic, and 8% of Asian American HCWs were vaccine-hesitant. Age, education level, occupation, history of COVID-19, and COVID-19 related knowledge were predictive of vaccine hesitancy. We found significant variations in COVID-19 related knowledge and reasons for vaccine hesitancy among Black (governmental mistrust), Hispanic (preference for physiological immunity), and Asian-American HCWs (concern about side effects) who were vaccine-hesitant or not. Our findings highlight racial and ethnic differences in vaccine-hesitancy and barriers to vaccination among HCWs of color. This study indicates the necessity of targeted interventions to reduce vaccine hesitancy that are mindful of the disparities in knowledge and access and differences between and among racial and ethnic groups.

Advance online publication.

Abstract:

Healthcare providers who use controlling or coercive strategies may compel short-term enactment of HIV and sexually transmitted infection prevention behaviors but may inadvertently undermine their client’s motivation to maintain those behaviors in the absence of external pressure. Autonomous motivation refers to the self-emanating and self-determined drive for engaging in health behaviors. It is associated with long-term maintenance of health behaviors. We used structural equation modeling to investigate whether autonomy support was associated with increased odds of therapeutic serum levels of pre-exposure prophylaxis, through a pathway that satisfies basic psychological needs for autonomous self-regulation and competence regarding pre-exposure prophylaxis use. We also investigated whether autonomy support was associated with decreased odds of condomless anal intercourse via the same psychological needs-satisfaction pathway of autonomous self-regulation and competence regarding condom use. We tested these two theorized pathways using secondary data from a longitudinal sample of Black men who have sex with men from across three cities in the US (N = 226). Data from the sample fit the theorized models regarding the pathways by which autonomy support leads to the presence of therapeutic PrEP levels in serum (χ2 = 0.56; RMSEA = 0.04; CFI = .99, TLI = 0.98) and how it also leads to decreased odds of condomless anal intercourse (χ2 = 0.58; RMSEA = 0.03; CFI = 0.99; TLI = 0.98). These findings provide scientific evidence for the utility of self-determination theory as a model to guide intervention approaches to optimize the implementation and impact of PrEP for Black men who have sex with men.

Advance online publication.

Abstract: Long-acting injectable antiretroviral medications are new to HIV treatment. People with HIV may benefit from a treatment option that better aligns with their preferences, but could also face new challenges and barriers. Authors from the fields of HIV, substance use treatment, and mental health collaborated on this commentary on the issues surrounding equitable implementation and uptake of LAI ART by drawing lessons from all three fields. We employ a socio-ecological framework beginning at the policy level and moving through the community, organizational, interpersonal, and patient levels. We look at extant literature on the topic as well as draw from the direct experience of our clinician-authors.

(2022). Use of COVID-19 testing in the first year of the COVID-19 pandemic among cohorts of people at the intersection of drug use and HIV. Drug and alcohol dependence, 109622. Advance online publication.

Abstract: 

People living with (PLWH) and at risk for HIV and people who use drugs (PWUD) are at heightened risk for health consequences of COVID-19 because of compromised immunity and high comorbidities. We studied their use of COVID-19 testing during the first year of the COVID-19 pandemic. Eight NIDA funded cohorts across North America in the Collaborating Consortium of Cohorts Producing NIDA Opportunities (C3PNO) administered multiple waves of a COVID-19 survey. Respondents were at least 18 years of age, half PLWH, and many active substance users. Wave one of the COVID-19 survey was May-November, 2020 and wave two October 2020-April 2021. Associations of COVID-19 testing with demographics, socio-demographics, substance use, and HIV-status were assessed. Of the 3762 responses from 2331 individuals, half reported ever COVID-19 testing (49.1 %), with 4.3 % reporting a positive test (163/3762 surveys=4.3 %) and 41.5 % of people reporting current symptoms reported having been tested. In multivariable analysis adjusting for age, sex, and cohort type associations with COVID-19 testing included African American/Black identification compared to Caucasian/white (adjusted odds ratio (AOR)= 0.68; 95 % confidence interval (CI) 0.53, 0.88); being unemployed (AOR=0.61; 95 % CI 0.51, 0.73), and living with HIV (AOR=0.76; 95 % CI0.65, 0.90). Findings from these C3PNO COVID-19 modules suggests that in the first year of the pandemic COVID-19 testing was not broadly accessed by these marginalized populations including PLWH and those unemployed. Factors associated with not testing may also parallel those for vaccination and identify populations needing better access to COVID-19 prevention.

Day-to-day impact of COVID-19 and other factors associated with risk of nonfatal overdose among people who use unregulated drugs in five cities in the United States and Canada. Drug and alcohol dependence, 109633. Advance online publication.

Abstract: 

Background: The COVID-19 pandemic has compounded the longstanding drug poisoning crisis in Canada and the United States (US). Research is needed to understand the contributions of COVID-19 and subsequent infection control measures. We sought to estimate the prevalence of and factors associated with nonfatal overdose among participants in nine prospective cohorts of people who use unregulated drugs (PWUD) in Canada and the US.

Methods: Data were derived from nine cohorts of PWUD in urban centres in Canada (Vancouver, BC) and the US (Baltimore, MD; Miami, FL; Chicago, IL; Los Angeles, CA) between May, 2020 and April, 2021. Multivariable logistic regression was used to identify factors associated with nonfatal overdose among participants who used unregulated drugs in the past month.

Results: Among 885 participants (including 253 females), 41 (4.6 %) experienced a non-fatal overdose in the past month, and 453 (51.2 %) reported being highly impacted day-to-day by the pandemic. In multivariable analyses, people who experienced a non-fatal overdose were more likely to be female (Adjusted Odds Ratio [AOR]=2.18;95 % Confidence Interval [CI]=1.10-4.30); unstably housed/homeless (AOR=2.16;95 % CI=1.11-4.26); engaged in medications for opioid use disorder (AOR=2.45;95 % CI=1.19-4.97); and highly impacted day-to-day (AOR=2.42;95 % CI=1.22-5.10).

Conclusion: Our findings may reflect characteristics of participants who experienced a compounding of vulnerabilities during the pandemic and thus are vulnerable to overdose, including women, those unstably housed/homeless, and those who perceived their daily lives were highly impacted by the pandemic. Multi-level interventions are needed to remediate the vulnerabilities and address the main driver of poisoning crisis.

Engaging Same-Day Peer Ambassadors to Increase Coronavirus Disease 2019 Vaccination Among People Experiencing Unsheltered Homelessness in Los Angeles County: A Hybrid Feasibility-Evaluation Study. The Journal of infectious diseases226(Supplement_3), S346–S352.

Abstract:

Background: This study aimed to evaluate the feasibility and acceptability of engaging unhoused peer ambassadors (PAs) in coronavirus disease 2019 (COVID-19) vaccination efforts to reach people experiencing unsheltered homelessness in Los Angeles County.

Methods: From August to December 2021, vaccinated PAs aged ≥18 years who could provide informed consent were recruited during vaccination events for same-day participation. Events were held at encampments, service providers (eg, housing agencies, food lines, and mobile showers), and roving locations around Los Angeles. PAs were asked to join outreach alongside community health workers and shared their experience getting vaccinated, receiving a $25 gift card for each hour they participated. Postevent surveys evaluated how many PAs enrolled and how long they participated. In October 2021, we added a preliminary effectiveness evaluation of how many additional vaccinations were attributable to PAs. Staff who enrolled the PAs estimated the number of additional people vaccinated because of talking with the PA.

Results: A total of 117 PAs were enrolled at 103 events, participating for an average of 2 hours. At events with the effectiveness evaluation, 197 additional people were vaccinated over 167 PA hours ($21.19 gift card cost per additional person vaccinated), accounting for >25% of all vaccines given at these events.

Discussion: Recruiting same-day unhoused PAs is a feasible, acceptable, and preliminarily effective technique to increase COVID-19 vaccination in unsheltered settings. The findings can inform delivery of other health services for people experiencing homelessness.

Prevalence and correlates of stocking up on drugs during the COVID-19 pandemic: Data from the C3PNO Consortium. Drug Alcohol Depend. 2022 Oct 6:109654. Epub ahead of print. PMID: 36266158; PMCID: PMC9535877.

Abstract:

Background: Data from the COVID-19 pandemic describes increases in drug use and related harms, especially fatal overdose. However, evidence is needed to better understand the pathways from pandemic-related factors to substance use behaviours. Thus, we investigated stockpiling drugs among people who use drugs (PWUD) in five cities in the United States and Canada.

Methods: We used data from two waves of interviews among participants in nine prospective cohorts to estimate the prevalence and correlates of stockpiling drugs in the previous month. Longitudinal correlates were identified using bivariate and multivariate generalized linear mixed-effects modeling analyses.

Results: From May 2020 to February 2021, we recruited 1873 individuals who completed 2242 interviews, of whom 217 (11.6%) reported stockpiling drugs in the last month at baseline. In the multivariate model, stockpiling drugs was significantly and positively associated with reporting being greatly impacted by COVID-19 (Adjusted Odds Ratio [AOR]= 1.21, 95% CI: 1.09-1.45), and at least daily use of methamphetamine (AOR = 4.67, 95% CI: 2.75-7.94) in the past month.

Conclusions: We observed that approximately one-in-ten participants reported stocking up on drugs during the COVID-19 pandemic. This behaviour was associated with important drug-related risk factors including high-intensity methamphetamine use. While these correlations need further inquiry, it is possible that addressing the impact of COVID-19 on vulnerable PWUD could help limit drug stockpiling, which may lower rates of high-intensity stimulant use.

Abstract:

Psychiatry has always been characterized by a range of different models of and approaches to mental disorder, which have sometimes brought progress in clinical practice, but have often also been accompanied by critique from within and without the field. Psychiatric nosology has been a particular focus of debate in recent decades; successive editions of the DSM and ICD have strongly influenced both psychiatric practice and research, but have also led to assertions that psychiatry is in crisis, and to advocacy for entirely new paradigms for diagnosis and assessment. When thinking about etiology, many researchers currently refer to a biopsychosocial model, but this approach has received significant critique, being considered by some observers overly eclectic and vague. Despite the development of a range of evidence-based pharmacotherapies and psychotherapies, current evidence points to both a treatment gap and a research-practice gap in mental health. In this paper, after considering current clinical practice, we discuss some proposed novel perspectives that have recently achieved particular prominence and may significantly impact psychiatric practice and research in the future: clinical neuroscience and personalized pharmacotherapy; novel statistical approaches to psychiatric nosology, assessment and research; deinstitutionalization and community mental health care; the scale-up of evidence-based psychotherapy; digital phenotyping and digital therapies; and global mental health and task-sharing approaches. We consider the extent to which proposed transitions from current practices to novel approaches reflect hype or hope. Our review indicates that each of the novel perspectives contributes important insights that allow hope for the future, but also that each provides only a partial view, and that any promise of a paradigm shift for the field is not well grounded. We conclude that there have been crucial advances in psychiatric diagnosis and treatment in recent decades; that, despite this important progress, there is considerable need for further improvements in assessment and intervention; and that such improvements will likely not be achieved by any specific paradigm shifts in psychiatric practice and research, but rather by incremental progress and iterative integration.

Wiss DA, Prelip ML, Upchurch DM, von Ehrenstein OS, Tomiyama AJ, Shoptaw SJ. Perceived social support moderates the association between household dysfunction adverse childhood experiences (ACEs) and self-reported drug use among men who have sex with men in Los Angeles, California. Int J Drug Policy. 2022 Nov 2;110:103899. Epub ahead of print. PMID: 36334318.

Abstract: 

Background: Adverse childhood experiences (ACEs) have been shown to be associated with drug use in adulthood. The single ACE of household substance use history (part of the household dysfunction category) has frequently been associated with drug use. Resilience factors such as perceived social support appear to buffer the association between ACEs and drug use and may be particularly relevant for urban men who have sex with men (MSM). The current study of low-income mostly Black and Latino MSM aims to investigate whether the cumulative ACE score predicts self-reported drug use in a dose-response manner and whether this potential association differs by perceived social support.

Methods: Data was utilized from a longitudinal study of MSM (mean age=34; SD=7.1) with varied substance use behaviors (n = 321) collected between August 2014 and April 2022. Cumulative, household dysfunction ACEs, and the single ACE of household substance use history were investigated as predictors of self-reported drug use (methamphetamine, ecstasy, cocaine/crack, heroin/fentanyl, party drugs [GHB, special K, mushrooms, LSD/acid], other drugs [bath salts, PCP]) during the past six months in mixed-effects logistic regression models, with moderation analyses by perceived social support (measured by the Multidimensional Scale of Perceived Social Support) across all models using stratified analysis and one model of multiplicative interaction.

Results: There was no suggestion of a dose-response relationship between the number of ACEs and the predicted probability of self-reported drug use. Cumulative ACEs did not predict the outcome overall (aOR=1.99; 95% CI: 0.86-4.59), however, a positive association was estimated for individuals reporting lower levels of perceived social support (aOR=2.80; 95% CI: 0.97-8.06). The dimension of household dysfunction had a positive association with drug use (aOR=1.32; 95% CI: 1.00-1.74) whereas the dimension of childhood maltreatment did not. The association between household dysfunction and drug use was moderated by the perception of social support, with those reporting lower levels having greater odds of reporting drug use (aOR=2.94; 95% CI: 1.04-8.31). The association between household substance use history and self-reported drug use was similarly moderated by perceived social support in a multiplicative interaction model (p = .02).

Conclusion: Perceived social support emerged as a potential buffering factor for any reported drug use, particularly for the single ACE of household substance use history. Given that the association between ACEs and drug use was weak among those with higher levels of perceived social support, promotion of social ties in the community may help reduce the burden of substance use among MSM exposed to ACEs.

Abstract:

Background: Sexually transmitted infections (STIs), STI reinfection, Human Immunodeficiency Virus (HIV) acquisition and changes in behaviors following an STI were examined in a cohort of men who have sex with men (MSM) in Los Angeles, CA.

Methods: Data from a longitudinal study of MSM enrolled from 2014 with at least one follow-up visit through March 2020 were analyzed (n = 447; 1,854 visits). Study visits every 6 months included self-interviews for sexual behaviors, substance use, and specimen collection for chlamydia, gonorrhea, syphilis, and HIV testing. Changes in behaviors were assessed using McNemar’s test and participants not diagnosed with an STI served as controls for a difference-in-differences (DiD) analysis of changes over time.

Results: Cumulative incidence of an STI was 55% (248/447). At 24-months post STI diagnosis methamphetamine use declined from 50% to 35% (p < .01), and median number of sex partners declined from 5 (IQR: 2-11) to 2 (IQR: 1-6)(p < .01). Among participants at risk for HIV and diagnosed with an STI (n = 102), PrEP use was 35% and HIV-seroconversion was 6%. Based on DiD analyses, participants diagnosed with an STI had higher levels of substance and higher number of sex partners when compared to those with no STIs, however, declines in these behaviors were comparable to participants not diagnosed with an STI (pDID > 0.05).

Conclusions: Despite behavior modifications following an STI diagnosis, STI/HIV incidence was high, suggesting that MSM with STIs occupy sexual networks where reductions in sexual and substance using behaviors do not protect them from ongoing exposure to STIs and HIV.

Acheson LS, Ezard N, Lintzeris N, Dunlop A, Brett J, Rodgers C, Gill A, Christmass M, McKetin R, Farrell M, Shoptaw S, Siefried KJ. Trial protocol of an open label pilot study of lisdexamfetamine for the treatment of acute methamphetamine withdrawal. PLoS One. 2022 Oct 3;17(10):e0275371. PMID: 36190973; PMCID: PMC9529099.

Abstract: 

Introduction: Methamphetamine (MA) use disorder is an important public health concern. MA withdrawal is often the first step in ceasing or reducing use. There are no evidence-based withdrawal treatments, and no medication is approved for the treatment of MA withdrawal. Lisdexamfetamine (LDX) dimesilate, used in the treatment of attention deficit hyperactivity disorder and binge eating disorder has the potential as an agonist therapy to ameliorate withdrawal symptoms, and improve outcomes for patients.

Methods: A single arm, open-label pilot study to test the safety and feasibility of LDX for the treatment of MA withdrawal. Participants will be inpatients in a drug and alcohol withdrawal unit, and will receive a tapering dose of LDX over five days: 250mg LDX on Day 1, reducing by 50mg per day to 50mg on Day 5. Optional inpatient Days 6 and 7 will allow for participants to transition to ongoing treatment. Participants will be followed-up on Days 14, 21 and 28. All participants will also receive standard inpatient withdrawal care. The primary outcomes are safety (measured by adverse events, changes in vital signs, changes in suicidality and psychosis) and feasibility (the time taken to enrol the sample, proportion of screen / pre-screen failures). Secondary outcomes are acceptability (treatment satisfaction questionnaire, medication adherence, concomitant medications, qualitative interviews), retention to protocol (proportion retained to primary and secondary endpoints), changes in withdrawal symptoms (Amphetamine Withdrawal Questionnaire) and craving for MA (visual analogue scale), and sleep outcomes (continuous actigraphy and daily sleep diary).

Discussion: This is the first study to assess lisdexamfetamine for the treatment of acute MA withdrawal. If safe and feasible results will go to informing the development of multi-centre randomised controlled trials to determine the efficacy of the intervention.

Abstract:

Background: Social genomics has demonstrated altered inflammatory and type I interferon (IFN) gene expression among people experiencing chronic social adversity. Adverse social experiences such as discrimination and violence are linked to stimulant misuse and HIV, conditions that dysregulate inflammatory and innate antiviral responses, leading to increased HIV viral replication and risk of chronic diseases.

Purpose: We aimed to determine whether methamphetamine (MA) use, unsuppressed HIV viral load (VL) (≥200 c/mL), and experienced intimate partner violence (IPV) (past 12 months) predicted inflammatory and type I IFN gene expression in HIV-positive Black and Latinx men who have sex with men (MSM).

Methods: Participants were 147 HIV-positive Black and Latinx MSM recruited from the mSTUDY, a cohort of 561 MSM aged 18-45 in Los Angeles, CA, of whom half are HIV-positive and substance-using. Transcriptomic measures of inflammatory and type I IFN activity were derived from RNA sequencing of peripheral blood mononuclear cells and matched to urine drug tests, VL, and survey data across two time points 12 months apart. Analysis used linear random intercept modeling of MA use, unsuppressed VL, and experienced IPV on inflammatory and type I IFN expression.

Results: In adjusted models, MA use predicted 27% upregulated inflammatory and 31% upregulated type I IFN expression; unsuppressed VL predicted 84% upregulated type I IFN but not inflammatory expression; and experienced IPV predicted 31% upregulated inflammatory and 26% upregulated type I IFN expression.

Conclusions: In Black and Latinx MSM with HIV, MA use, unsuppressed VL, and experienced IPV predicted upregulated social genomic markers of immune functioning.

Abstract:

Background: Alterations in the gut microbiome have been associated with HIV infection, but the relative impact of HIV versus other factors on the gut microbiome has been difficult to determine in cross-sectional studies.

Methods:To address this, we examined the gut microbiome, serum metabolome, and cytokines longitudinally within 27 individuals before and during acute HIV using samples collected from several ongoing cohort studies. Matched control participants (n=28) from the same cohort studies without HIV but at similar behavioral risk were used for comparison.

Findings: We identified few changes in the microbiome during acute HIV infection, but did find alterations in serum metabolites involving secondary bile acid (lithocholate sulfate, glycocholenate sulfate) and amino acid metabolism (3-methyl-2-oxovalerate, serine, cysteine, N-acetylputrescine). Greater microbiome differences, including decreased Bacteroides spp and increased Megasphaera elsdenii, were seen when comparing pre-HIV infection visits to matched at-risk controls. Those who acquired HIV also had elevated inflammatory cytokines (TNF-α, B cell activating factor, IL-8) and bioactive lipids (palmitoyl-sphingosine-phosphoethanolamide and glycerophosphoinositol) prior to HIV acquisition compared to matched controls.

Interpretation: Longitudinal sampling identified pre-existing microbiome differences in participants with acute HIV compared to matched control participants observed over the same period. These data highlight the importance of increasing understanding of the role of the microbiome in HIV susceptibility.

Brief Report: HIV Infection Does Not Explain Higher Nicotine Metabolism in People Living With HIV. J Acquir Immune Defic Syndr. 2022 Dec 15;91(5):497-501. PMID: 36083509; PMCID: PMC9649853.

Abstract: 

Background: Smoking contributes to significant morbidity and mortality in people with HIV. People with HIV have relatively high nicotine metabolism rates, as measured by the nicotine metabolite ratio (NMR, 3-hydroxycotinine/cotinine). A higher NMR is associated with difficulty quitting smoking. We hypothesized that HIV infection might upregulate nicotine metabolism.

Setting: A retrospective study of male current smokers in the Multicenter AIDS Cohort Study who HIV seroconverted between 1985 and 1993.

Methods: Eligibility included having plasma stored before and after confirmed HIV seroconversion and current tobacco use. Samples were selected from the closest available visits before (median 3.3 months) and after (median 9.4 months) seroconversion. Antiretroviral therapy use was exclusionary. Cotinine and 3-hydroxycotinine were measured using liquid chromatography-tandem mass spectrometry. We compared NMR from plasma pre-HIV and post-HIV infection using signed-rank tests. We targeted a sample size of 71 pairs to achieve 80% power to detect a 0.1 unit increase in NMR with P = 0.05.

Results: We analyzed paired samples from 78 participants; the median age was 34.5 years [interquartile range (IQR 29-40 years)]. The median NMR pre-HIV and post-HIV was 0.45 (IQR 0.32-0.54) and 0.46 (IQR 0.34-0.56), respectively. The median change in NMR postseroconversion was +0.01 (IQR -0.05, +0.09), P = 0.25. Stratification of median change in NMR by timing between samples or time since HIV seroconversion did not alter this finding.

Conclusions: Acquiring HIV had no measurable effect on NMR. We postulate that upregulation of the NMR may be due to direct pharmacologic effects of HIV medications or metabolic changes in response to HIV infection.

Emerging evidence from a systematic review of safety of pre-exposure prophylaxis for pregnant and postpartum women: where are we now and where are we heading? J Int AIDS Soc. 2020 Jan;23(1):e25426. PMCID: PMC6948023.

Abstract:

Introduction: HIV incidence is high during pregnancy and breastfeeding with HIV acquisition risk more than doubling during pregnancy and the postpartum period compared to when women are not pregnant. The World Health Organization recommends offering pre-exposure prophylaxis (PrEP) to pregnant and postpartum women at substantial risk of HIV infection. However, maternal PrEP national guidelines differ and most countries with high maternal HIV incidence are not offering PrEP. We conducted a systematic review of recent research on PrEP safety in pregnancy to inform national policy and rollout.

Methods: We used a standard Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) approach to conduct a systematic review by searching for completed, ongoing, or planned PrEP in pregnancy projects or studies from clinicaltrials.gov, PubMed and NIH RePORTER from 2014 to March 2019. We performed a systematic review of studies that assess tenofovir disoproxil fumarate (TDF)-based oral PrEP safety in pregnant and breastfeeding HIV-uninfected women.

Results and discussion: We identified 14 completed (n = 5) and ongoing/planned (n = 9) studies that evaluate maternal and/or infant outcomes following PrEP exposure during pregnancy or breastfeeding. None of the completed studies found differences in pregnancy or perinatal outcomes associated with PrEP exposure. Nine ongoing studies, to be completed by 2022, will provide data on >6200 additional PrEP-exposed pregnancies and assess perinatal, infant growth and bone health outcomes, expanding by sixfold the data on PrEP safety in pregnancy. Research gaps include limited data on (1) accurately measured PrEP exposure within maternal and infant populations including drug levels needed for maternal protection; (2) uncommon perinatal outcomes (e.g. congenital anomalies); (3) infant outcomes such as bone growth beyond one year following PrEP exposure; (4) outcomes in HIV-uninfected women who use PrEP during pregnancy and/or lactation.

Conclusions: Expanding delivery of PrEP is an essential strategy to reduce HIV incidence in pregnancy and breastfeeding women. Early safety studies of PrEP among pregnant women without HIV infection are reassuring and ongoing/planned studies will contribute extensive new data to bolster the safety profile of PrEP use in pregnancy. However, addressing research gaps is essential to expanding PrEP delivery for women in the context of pregnancy.

Methamphetamine use and adoption of preventive behaviors early in the COVID-19 pandemic among men who have sex with men in Los Angeles, California. Drug Alcohol Depend Rep. 2022 Dec;5:100097. Epub 2022 Sep 29. PMID: 36193108; PMCID: PMC9519521.

Abstract:

Background: Methamphetamine (MA) use increased during COVID-19, with men who have sex with men (MSM) exhibiting 3-fold greater use than heterosexual men. Understanding links between reported MA use and COVID-19 prevention behaviors among MSM can inform current transmission risks for HIV, Monkeypox, and other infectious diseases.

Methods: This study assesses relationships between self-reported pattern of MA use (past six months; past two weeks) and reported COVID-19 preventive behaviors, adjusting for participant characteristics (HIV serostatus, race/ethnicity, employment and housing stability), in a cohort of ethnically diverse MSM in Los Angeles, California, between April 1 and September 30, 2020.

Results: Compared to those who reported no MA use, MSM who reported weekly or more MA use in the past six months were significantly less likely to use COVID-19 protective behaviors of physical distancing (61.8% vs. 81.6%; AOR = 0.39, 95% CI [0.19, 0.81]), of avoiding public transportation (34.5% vs. 60.3%; AOR = 0.42, 95% CI [0.21, 0.83]) and of avoiding traveling overall (32.7% vs. 62.6%; AOR = 0.32, 95% CI [0.16, 0.63]). Parallel findings were observed in analyses of past two-week reported MA use and COVID-19 protective behaviors.

Conclusion: Findings highlight ways in which reported MA use frequency links with avoidance of reported preventive behaviors for COVID-19 in urban diverse MSM. Findings also provide evidence to guide public health interventions in future outbreaks of COVID-19 and other infectious diseases among MSM.

Li MJ, Shoptaw SJ. Clinical management of psychostimulant withdrawal: review of the evidence. Addiction. 2023 Apr;118(4):750-762. Epub 2022 Dec 12. PMID: 36401591.

Abstract:

It is estimated that a majority of people who use psychostimulants, particularly methamphetamine (MA) and cocaine, experience withdrawal upon abstinence from sustained use. This review of clinical research reports the evidence regarding biomedical and behavioral treatments for psychostimulant withdrawal symptoms. It provides a framework for clinicians and scientists to increase impact on attenuating MA and cocaine withdrawal during initial and sustained abstinence. Articles reviewed included reports of controlled clinical trials (randomized or non-randomized) reporting at least one withdrawal symptom among the outcomes or specifically studying patients in withdrawal. Potential efficacy for MA withdrawal is noted for a few medications (mirtazapine, naltrexone, bupropion) and repetitive transcranial magnetic stimulation during acute (first week), early protracted (weeks 2-4) and late protracted (> 4 weeks) withdrawal phases. Topiramate shows mixed evidence of efficacy for cocaine withdrawal. In general, there is inconsistent signal for biomedical and behavioral treatments on MA and cocaine withdrawal.

Blair CS, Gandhi M, Shoptaw S, Blades C, Clark JL. Contingency Management for Integrated Harm Reduction Among Men Who Have Sex with Men Who Use Methamphetamine in Los Angeles: A Pilot Assessment. AIDS Behav. 2022 Nov 21. Epub ahead of print. PMID: 36414775.

Abstract:

Methamphetamine (MA) use is associated with HIV transmission among men who have sex with men (MSM) and lapses in medication adherence. Contingency Management (CM) is effective in reducing MA use, but studies of CM to support adherence to HIV prevention or treatment are limited. We conducted a pilot trial of a CM intervention to reduce MA use and improve PrEP/ART adherence among MSM prescribed a tenofovir (TFV)-based regimen for HIV prevention or treatment. Participants were randomly assigned to receive escalating incentives for either MA abstinence or TFV adherence (based on point-of-care urine testing), and to a monitoring schedule of either 2 or 3 visits/week for 4 weeks. 19 MSM were randomized to either CM for MA use or CM for PrEP/ART adherence (median age: 38; IQR: 28-46) and 15 were living with HIV. Participants attended 95.7% (67/70) of scheduled visits in the 2x/week arm and 74.8% (74/99) in the 3x/week arm. TFV adherence was higher among participants in the TFV adherence arm with 93.5% (n = 72/77) of urine samples positive for TFV, compared to 76.6% (n = 49/64) in the MA abstinence arm (p = 0.007). Participants in the MA abstinence arm had more urine samples negative for MA metabolites (20.3%, n = 13/64) than those receiving CM for TFV adherence (6.5%, n = 5/77; p = 0.021). A CM model for MA abstinence and PrEP/ART adherence using twice-weekly visits and urine testing for MA and TFV for MSM who use MA is feasible and potentially effective as an integrated harm reduction strategy.

Wiss DA, Prelip ML, Upchurch DM, von Ehrenstein OS, Tomiyama AJ, Shoptaw SJ. Perceived social support moderates the association between household dysfunction adverse childhood experiences (ACEs) and self-reported drug use among men who have sex with men in Los Angeles, California. Int J Drug Policy. 2022 Dec;110:103899. Epub 2022 Nov 2. PMID: 36334318.

Abstract:

Background: Adverse childhood experiences (ACEs) have been shown to be associated with drug use in adulthood. The single ACE of household substance use history (part of the household dysfunction category) has frequently been associated with drug use. Resilience factors such as perceived social support appear to buffer the association between ACEs and drug use and may be particularly relevant for urban men who have sex with men (MSM). The current study of low-income mostly Black and Latino MSM aims to investigate whether the cumulative ACE score predicts self-reported drug use in a dose-response manner and whether this potential association differs by perceived social support.

Methods: Data was utilized from a longitudinal study of MSM (mean age=34; SD=7.1) with varied substance use behaviors (n = 321) collected between August 2014 and April 2022. Cumulative, household dysfunction ACEs, and the single ACE of household substance use history were investigated as predictors of self-reported drug use (methamphetamine, ecstasy, cocaine/crack, heroin/fentanyl, party drugs [GHB, special K, mushrooms, LSD/acid], other drugs [bath salts, PCP]) during the past six months in mixed-effects logistic regression models, with moderation analyses by perceived social support (measured by the Multidimensional Scale of Perceived Social Support) across all models using stratified analysis and one model of multiplicative interaction.

Results: There was no suggestion of a dose-response relationship between the number of ACEs and the predicted probability of self-reported drug use. Cumulative ACEs did not predict the outcome overall (aOR=1.99; 95% CI: 0.86-4.59), however, a positive association was estimated for individuals reporting lower levels of perceived social support (aOR=2.80; 95% CI: 0.97-8.06). The dimension of household dysfunction had a positive association with drug use (aOR=1.32; 95% CI: 1.00-1.74) whereas the dimension of childhood maltreatment did not. The association between household dysfunction and drug use was moderated by the perception of social support, with those reporting lower levels having greater odds of reporting drug use (aOR=2.94; 95% CI: 1.04-8.31). The association between household substance use history and self-reported drug use was similarly moderated by perceived social support in a multiplicative interaction model (p = .02).

Conclusion: Perceived social support emerged as a potential buffering factor for any reported drug use, particularly for the single ACE of household substance use history. Given that the association between ACEs and drug use was weak among those with higher levels of perceived social support, promotion of social ties in the community may help reduce the burden of substance use among MSM exposed to ACEs.

Nong T, Hodgkin D, Trang NT, Shoptaw SJ, Li MJ, Hai Van HT, Le G. A review of factors associated with methadone maintenance treatment adherence and retention in Vietnam. Drug Alcohol Depend. 2023 Feb 1;243:109699. Epub 2022 Dec 15. PMID: 36603363; PMCID: PMC9851667.

Abstract:

Background: Starting in 2008, Vietnam’s national MMT program expanded quickly, but it is struggling with increasing attrition rates and poor adherence among patients. Several studies have reported on MMT retention and adherence, but no overview has yet been published. The objective of this study is to fill that gap and to review factors associated with retention and adherence in MMT in Vietnam.

Methods: A systematic search was conducted using databases of literature – Pubmed, Cochrane, Scopus, Academic search premiere, and SoINDEX. Peer-reviewed empirical studies with full text in English discussing retention attrition and adherence regarding MMT in Vietnam were selected. The results were synthesized using qualitative methods.

Results: Adherence and retention rates varied among the 11 included studies. In general, patients in mountainous provinces had lower adherence and retention rates than those in big cities. Retention rates decreased with the studies’ follow-up period and had a downward trend over time. Factors associated with adherence and retention can be classified into three groups: individual, community, and institutional factors. Important individual factors areage, education, awareness of MMT and HIV, and co-occurring disorders and comorbidities. Stigma is the major community risk factor, and methadone daily dose, the distance between home and clinic, and clinic’s service hours are the three most important institutional factors.

Conclusions: The literature reviewed identifies important factors associated with MMT adherence and retention in Vietnam. The findings suggest further research exploring both subjective and objective factors and more policies to remove social and structural barriers to enhance treatment outcomes.

Substance Use Treatment Utilization Among Women With and Without Human Immunodeficiency Virus. Open Forum Infect Dis. 2022 Dec 21;10(1):ofac684. PMID: 36655189; PMCID: PMC9835749.

Abstract:

Background: Substance use (SU) contributes to poor health outcomes, yet limited data exist to inform strategies to optimize SU treatment among persons with human immunodeficiency virus (HIV). We describe SU and SU treatment utilization among women with and without HIV in the Women’s Interagency HIV Study (WIHS).

Methods: We included data from women enrolled in WIHS from 2013 to 2020. Current SU was self-reported, nonmedical use of drugs in the past year, excluding use of only marijuana. SU treatment utilization was self-reported use of a drug treatment program in the past year. Multivariable regression models were used to investigate associations between participant characteristics and SU treatment.

Results: Among 2559 women (1802 women living with HIV [WWH], 757 women without HIV), 14% reported current SU. Among those with current SU (n = 367), 71% reported crack/cocaine followed by 40% reporting opioids, and 42% reported any treatment in the past year. The most common treatments were methadone (64%), Narcotics Anonymous (29%), inpatient programs (28%), and outpatient programs (16%). Among women using opioids (n = 147), 67% reported methadone use in the past year compared to 5% using buprenorphine/naloxone. Multivariable analysis showed lower odds of treatment utilization among WWH with concurrent alcohol or marijuana use. Visiting a psychiatrist/counselor was associated with higher odds of treatment. Among WWH, SU treatment was not associated with HIV-related clinical outcomes.

Conclusions: Treatment utilization was high, especially for methadone use. Our results highlight opportunities for accessing SU treatment for WWH, such as the need to prioritize buprenorphine and comprehensive, wraparound services in HIV care settings.

Morehead-Gee A, Üsküp DK, Omokaro U, Shoptaw S, Harawa NT, Heilemann MV. Relating ‘to her Human Side’: a Grounded Theory analysis of cosmetologists’ and aestheticians’ relationships with clients in Black American beauty salons to inform sexual health interventions. Cult Health Sex. 2022 Nov 14:1-18. Epub ahead of print. PMID: 36377185.

Abstract:

Due to the elevated incidence of HIV among Black American women, effective sexual health interventions are needed. To explore beauty salons as settings for such interventions, we examined Black American women stylists’ experiences discussing sex-related topics with Black American women clients. Constructivist Grounded Theory methodology guided data collection and analysis. Individual intensive interviews were conducted in 2019 with 16 Black women cosmetologists and/or aestheticians who served Black women in Southern California. Analyses generated grounded theory which we refer to as Relating ‘to her Human Side’: Black American cosmetologist-client relationship building model. The model highlights the importance of three sets of practices: 1) playing different roles to appeal to clients’ varying wants and needs, 2) creating a comfortable atmosphere, and 3) establishing a judgement-free zone. Stylists put clients at ease and consequently, clients shared stories regarding sex and relationships freely. Stylists’ actions built trusting relationships with clients, thus crafting beauty salons as atmospheres favourable for sex-related conversations and potential sexual health interventions.

Bupropion and Naltrexone in Methamphetamine Use Disorder. The New England journal of medicine384(2), 140–153.

Abstract: 

Background: The use of naltrexone plus bupropion to treat methamphetamine use disorder has not been well studied.

Methods: We conducted this multisite, double-blind, two-stage, placebo-controlled trial with the use of a sequential parallel comparison design to evaluate the efficacy and safety of extended-release injectable naltrexone (380 mg every 3 weeks) plus oral extended-release bupropion (450 mg per day) in adults with moderate or severe methamphetamine use disorder. In the first stage of the trial, participants were randomly assigned in a 0.26:0.74 ratio to receive naltrexone-bupropion or matching injectable and oral placebo for 6 weeks. Those in the placebo group who did not have a response in stage 1 underwent rerandomization in stage 2 and were assigned in a 1:1 ratio to receive naltrexone-bupropion or placebo for an additional 6 weeks. Urine samples were obtained from participants twice weekly. The primary outcome was a response, defined as at least three methamphetamine-negative urine samples out of four samples obtained at the end of stage 1 or stage 2, and the weighted average of the responses in the two stages is reported. The treatment effect was defined as the between-group difference in the overall weighted responses.

Results: A total of 403 participants were enrolled in stage 1, and 225 in stage 2. In the first stage, 18 of 109 participants (16.5%) in the naltrexone-bupropion group and 10 of 294 (3.4%) in the placebo group had a response. In the second stage, 13 of 114 (11.4%) in the naltrexone-bupropion group and 2 of 111 (1.8%) in the placebo group had a response. The weighted average response across the two stages was 13.6% with naltrexone-bupropion and 2.5% with placebo, for an overall treatment effect of 11.1 percentage points (Wald z-test statistic, 4.53; P<0.001). Adverse events with naltrexone-bupropion included gastrointestinal disorders, tremor, malaise, hyperhidrosis, and anorexia. Serious adverse events occurred in 8 of 223 participants (3.6%) who received naltrexone-bupropion during the trial.

Conclusions: Among adults with methamphetamine use disorder, the response over a period of 12 weeks among participants who received extended-release injectable naltrexone plus oral extended-release bupropion was low but was higher than that among participants who received placebo.

Geographical and socioeconomic disparities in opioid access in Mexico, 2015-19: a retrospective analysis of surveillance data. The Lancet. Public health6(2), e88–e96.

Abstract: 

Background: In 2015, Mexico implemented regulatory changes and an electronic system to improve access to prescription opioids. We aimed to investigate trends in opioid dispensing after the implementation of these changes and assess how opioid dispensing varied geographically and by socioeconomic status.

Methods: In this retrospective analysis of prescription medication surveillance data, we analysed dispensing data for group 1 medications (all opioids, including morphine, methadone, hydromorphone, oxycodone, tapentadol, fentanyl, sufentanil, and remifentanil) obtained from the Federal Commission for the Protection against Sanitary Risk database for 32 states and six large metropolitan areas in Mexico. We calculated crude annual opioid prescriptions per 10 000 people at the national, state, and municipal levels. Adapting methods from the report of the Lancet Commission on Palliative Care and Pain Relief, we calculated the need for palliative opioids by state, and then assessed the observed opioid dispensing rates as a percentage of expected need by geographical socioeconomic status. Within the six major metropolitan areas, we mapped the geocoded location of opioid prescriptions and assessed the association between opioid dispensing and socioeconomic status as well as the association between opioid dispensing and time to US border crossing for areas on the US-Mexico border.

Findings: Between June 25, 2015, and Oct 7, 2019, opioid dispensing rates increased by an average of 13% (95% CI 6·8-19·6) per quarter (3 months). The overall national opioid dispensing rate during the study period was 26·3 prescriptions per 10 000 inhabitants. States with a higher socioeconomic status had higher opioid dispensing rates than states with lower socioeconomic status (rate ratio [RR] 1·88, 95% CI 1·33-2·58, p=0·00016) after controlling for the estimated opioid requirement per state, the presence of methadone clinics, and the presence of tertiary hospitals and cancer centres. The same association between opioid dispensing and socioeconomic status was observed in the metropolitan areas, and in those metropolitan areas on the US-Mexico border a 20% decrease (RR 0·80, 95% CI 0·75-0·86) in opioid dispensation was observed per each SD increase (SD 17·1 min) in travel time to the border.

Interpretation: Measures introduced by the Mexican federal Government to increase opioid access for patients with palliative care needs were only marginally successful in raising opioid prescription rates. Opioid access should be improved for patients with palliative care needs who live in geographical areas of lower socioeconomic status.

Efficacy and Safety of the mRNA-1273 SARS-CoV-2 Vaccine. The New England journal of medicine384(5), 403–416.

Abstract: 

Background: Vaccines are needed to prevent coronavirus disease 2019 (Covid-19) and to protect persons who are at high risk for complications. The mRNA-1273 vaccine is a lipid nanoparticle–encapsulated mRNA-based vaccine that encodes the prefusion stabilized full-length spike protein of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes Covid-19.

Methods: This phase 3 randomized, observer-blinded, placebo-controlled trial was conducted at 99 centers across the United States. Persons at high risk for SARS-CoV-2 infection or its complications were randomly assigned in a 1:1 ratio to receive two intramuscular injections of mRNA-1273 (100 μg) or placebo 28 days apart. The primary end point was prevention of Covid-19 illness with onset at least 14 days after the second injection in participants who had not previously been infected with SARS-CoV-2.

Results: The trial enrolled 30,420 volunteers who were randomly assigned in a 1:1 ratio to receive either vaccine or placebo (15,210 participants in each group). More than 96% of participants received both injections, and 2.2% had evidence (serologic, virologic, or both) of SARS-CoV-2 infection at baseline. Symptomatic Covid-19 illness was confirmed in 185 participants in the placebo group (56.5 per 1000 person-years; 95% confidence interval [CI], 48.7 to 65.3) and in 11 participants in the mRNA-1273 group (3.3 per 1000 person-years; 95% CI, 1.7 to 6.0); vaccine efficacy was 94.1% (95% CI, 89.3 to 96.8%; P<0.001). Efficacy was similar across key secondary analyses, including assessment 14 days after the first dose, analyses that included participants who had evidence of SARS-CoV-2 infection at baseline, and analyses in participants 65 years of age or older. Severe Covid-19 occurred in 30 participants, with one fatality; all 30 were in the placebo group. Moderate, transient reactogenicity after vaccination occurred more frequently in the mRNA-1273 group. Serious adverse events were rare, and the incidence was similar in the two groups.

Conclusions: The mRNA-1273 vaccine showed 94.1% efficacy at preventing Covid-19 illness, including severe disease. Aside from transient local and systemic reactions, no safety concerns were identified.

Responding to the Opioid Epidemic: Educational Competencies for Pain and Substance Use Disorder from the Medical Schools of the University of California. Pain medicine (Malden, Mass.)22(1), 60–66.

Abstract: 

Objective: The University of California (UC) leadership sought to develop a robust educational response to the epidemic of opioid-related deaths. Because the contributors to this current crisis are multifactorial, a comprehensive response requires educating future physicians about safe and effective management of pain, safer opioid prescribing, and identification and treatment of substance use disorder (SUD).

Methods: The six UC medical schools appointed an opioid crisis workgroup to develop educational strategies and a coordinated response to the opioid epidemic. The workgroup had diverse specialty and disciplinary representation. This workgroup focused on developing a foundational set of educational competencies for adoption across all UC medical schools that address pain, SUD, and public health concerns related to the opioid crisis.

Results: The UC pain and SUD competencies were either newly created or adapted from existing competencies that addressed pain, SUD, and opioid and other prescription drug misuse. The final competencies covered three domains: pain, SUD, and public health issues related to the opioid crisis.

Conclusions: The authors present a novel set of educational competencies as a response to the opioid crisis. These competencies emphasize the subject areas that are fundamental to the opioid crisis: pain management, the safe use of opioids, and understanding and treating SUD.

Abstract: 

Background: Transgender people are at a high risk of suicidal ideation, suicide attempts, and deaths. Among transgender individuals, 77% and 41% engage in suicidal ideation and suicide attempt in their lifetime, respectively, which exceeds the general population rates (9.2% and 2.7%, respectively). Traditionally, suicide risk factors have been studied over a long period between measurements, making it difficult to understand the short-term variability in suicide risk. Mobile phone apps offer an opportunity to understand the immediate precursors of suicidality through the assessment of behaviors and moods in real time. This is the first study to use a mobile phone app (TransLife) to understand the short-term risk factors for suicide among transgender individuals.

Objective: This study aims to beta test the usability of an evidence-informed mobile health (mHealth) suicide prevention phone app, TransLife. The primary aims are to obtain preliminary data on user engagement and satisfaction with the app, and to assess the feasibility of completing ecological momentary assessments (mood logs) within the app.

Methods: We used qualitative methods and an exploratory research approach that combined naturalistic app use, focus groups, and semistructured phone interviews. The focus group was informed about the development of the prototype. We conducted a 3-week evaluation to determine engagement and obtain detailed user feedback about the app. After participation in the pilot, phone-based, semistructured, and audio-recorded exit interviews were conducted with the research participants.

Results: In total, 16 transgender individuals participated in this study. On average, users logged in 4 (SD 2.7) times a week and spent approximately 5 (SD 3.5) minutes on the app per log-in. A total of 6 major themes emerged in this study. These themes focused on the app’s functionality, satisfaction with using the app, perceived ease of use, perceived safety of providing personal data within the app, trusting the app enough to share personal feelings, and features that make this app engaging. These themes suggest that TransLife is an engaging, useful, and acceptable mHealth intervention. Participants reported that the app was easy to use and understand, supported mental self-care, promoted self-awareness, and helped them identify triggers of negative moods.

Conclusions: The results of this pilot study indicate that TransLife is an engaging, acceptable, and potentially effective mHealth intervention. Transgender participants reported many advantages of using TransLife, such as being able to track their mood, connecting to the community, and accessing local resources. This study provides initial support for the acceptability and usability of TransLife as an mHealth intervention designed for the transgender community.

Sharp decline in hospital and emergency department initiated buprenorphine for opioid use disorder during COVID-19 state of emergency in California. Journal of substance abuse treatment123, 108260.

Abstract:

The California Bridge Program supports expansion of medications for opioid use disorder (MOUD) in emergency departments (EDs) and hospital inpatient units across the state. Here, we describe the change in activity before and after the coronavirus disease 2019 (COVID-19) California statewide shutdown. Of the 70 participating hospitals regionally distributed across California, 52 report MOUD-related activity monthly. We analyzed data on outcomes of OUD care and treatment: identification of OUD, acceptance of referral, receipt of buprenorphine prescription, administration of buprenorphine, and follow-up linkage to outpatient OUD treatment, from May 2019 to April 2020. In estimating the expected number of patients who met each outcome in April 2020, we found decreases in the expected to observed number of patients across all outcomes (all p-values<0.002): 37% (from 1053 to 667) decrease in the number of patients identified with OUD, 34% (from 632 to 420) decrease in the number of patients who accepted a referral, 48% (from 521 to 272) decrease in the number of patients who were prescribed buprenorphine, 53% (from 501 to 234) decrease in the number of patients who were administered buprenorphine, and 33% (from 416 to 277) decrease in the number of patients who attended at least one follow-up visit for addiction treatment. The COVID-19 California statewide shutdown was associated with an abrupt and large decrease in the progress toward expanded access to OUD treatment.

Development and Validation of the Personalized Sexual Health Promotion (SexPro) HIV Risk Prediction Model for Men Who Have Sex with Men in the United States. AIDS and behavior24(1), 274–283.

Abstract: 

Accurate HIV risk assessment among men who have sex with men (MSM) is important to help providers assess risk, and target HIV prevention interventions. We sought to develop an evidence-based HIV risk assessment tool for US MSM that is inclusive of Black MSM. Data from four large longitudinal cohorts of MSM were used to develop (EXPLORE), and validate (VAX004, HPTN061, and HVTN505). These data included visits in which participants self-reported HIV risk behavior and underwent HIV testing. We developed a pooled logistic model for incident HIV infection based on self-reported risk behaviors during the 6 months before each study visit. A total of 4069 MSM were used for the development cohort, and 8047 MSM in the three validation cohorts through 2013. The final model includes age (< 35, ≥ 35); Black race and Latino ethnicity; numbers of HIV-negative anal sex partners; number of insertive or receptive anal intercourse episodes; having 1 HIV-negative partner only; self-reported substance use; and bacterial sexually transmitted infection diagnosis. The model showed good discrimination in internal validation (C-statistic = 79.5). The external validation cohorts also showed good discrimination, with C-statistics of 73.1, 71.0, 71.9 in VAX004, HPTN061, and HVTN505 respectively, and acceptable calibration. We developed and validated an HIV risk assessment tool for MSM, which showed good predictive ability, including among the largest cohort of HIV-uninfected Black MSM in the US. This tool is available online (mysexpro.org) and can be used by providers to support targeting of HIV prevention interventions such as pre-exposure prophylaxis for MSM.

Voting with their feet: Social factors linked with treatment for opioid use disorder using same-day buprenorphine delivered in California hospitals. Drug and alcohol dependence222, 108673.

Abstract: 

Background: Medication for opioid use disorder (MOUD) using buprenorphine in primary or specialty care settings is accessed primarily by persons with private health insurance, stable housing, and no polysubstance use. This paper applies Social Cognitive Theory to frame links between social factors and treatment outcomes among patients with social and economic disadvantages who are seeking MOUD at California Bridge Program (CA Bridge) hospitals.

Methods: Electronic medical records for patients identified with OUD between January-April, 2020 receiving care at CA Bridge hospitals defined outcomes: hospital-administered buprenorphine; provision of buprenorphine prescription at discharge. Multi-level models assessed whether social factors-housing status, insurance type, and co-methamphetamine use-predicted outcomes while accounting for group-level effects of treating hospital and controlling for age, race/ethnicity, and gender.

Results:15 CA Bridge hospitals yielded 845 patient records. Most patients received hospital-administered buprenorphine (58 %) and/or a buprenorphine prescription (55 %); 26 % received neither treatment. Patients with unstable housing had greater odds of hospital-administered buprenorphine compared to patients with stable housing. Patients with Medicaid had greater odds of receiving a buprenorphine prescription compared to patients with other insurance. Co-methamphetamine use was not associated with outcomes.

Conclusions: Patients with OUD are successful in accessing same-day MOUD in CA Bridge hospital settings over a significant period. Importantly, access to MOUD in these settings was facilitated for patients traditionally not treated using buprenorphine, i.e., those with housing instability, Medicaid insurance, and co-methamphetamine use. Findings suggest barriers to MOUD for patients with social and economic disadvantages can be lowered by changing treatment delivery.

Abstract: 

Objective: To understand the relationship between drug use, food insecurity (FI) and mental health among men who have sex with men (MSM).

Design: Cohort study (2014-2019) with at least one follow-up.

Setting: Visits at 6-month intervals included self-assessment for FI and depressive symptoms. Urine testing results confirmed drug use. Factors associated with FI were assessed using multiple logistic regression with random effects for repeated measures. General structural equation modelling tested whether FI mediates the relationship between drug use and depressive symptoms.

Participants: Data were from HIV-positive and high-risk HIV-negative MSM in Los Angeles, CA (n 431; 1192 visits).

Results: At baseline, FI was reported by 50·8 % of participants, depressive symptoms in 36·7 % and 52·7 % of urine screening tests were positive for drugs (i.e. marijuana, opioids, methamphetamine, cocaine and ecstasy). A positive drug test was associated with a 96 % increase in the odds of being food insecure (95 % CI 1·26, 3·07). Compared to those with high food security, individuals with very low food security have a nearly sevenfold increase in the odds of reporting depressive symptoms (95 % CI 3·71, 11·92). Findings showed 14·9 % of the association between drug use (exposure) and depressive symptoms (outcome) can be explained by FI (mediator).

Conclusion: The prevalence of FI among this cohort of HIV-positive and high-risk HIV-negative MSM was high; the association between drug use and depressive symptoms was partially mediated by FI. Findings suggest that enhancing access to food and nutrition may improve mood in the context of drug use, especially among MSM at risk for HIV transmission.

Efficacy of Combining Varenicline and Naltrexone for Smoking Cessation and Drinking Reduction: A Randomized Clinical Trial. The American journal of psychiatry178(9), 818–828.

Abstract: 

Objective: Pharmacological treatments that can concomitantly address cigarette smoking and heavy drinking stand to improve health care delivery for these highly prevalent co-occurring conditions. This superiority trial compared the combination of varenicline and naltrexone against varenicline alone for smoking cessation and drinking reduction among heavy-drinking smokers.

Methods: This was a phase 2 randomized double-blind clinical trial. Participants (N=165) who were daily smokers and drank heavily received either 2 mg/day of varenicline plus 50 mg/day of naltrexone or 2 mg/day of varenicline plus matched placebo pills for 12 weeks. Primary outcomes were 7-day point prevalence of nicotine abstinence (bioverified by a breath CO reading ≤5 ppm) at the 26-week follow-up and number of drinks per drinking day during the 12-week treatment phase.

Results: Smoking abstinence at week 26 was significantly higher in the varenicline plus placebo condition than in the varenicline plus naltrexone condition (N=37 [45.1%] compared with N=22 [26.5%]). For drinks per drinking day, there was a medication effect favoring the combination of varenicline and naltrexone over varenicline alone across the 12-week treatment phase, although it did not meet the significance threshold.

Conclusions: These findings suggest that smoking cessation and drinking reduction can be concomitantly targeted with pharmacotherapy and that while varenicline alone may be sufficient as a smoking cessation aid in heavy-drinking smokers, the combination of varenicline and naltrexone may confer benefits with regard to drinking outcomes, particularly during the 12-week period of active medication treatment.

Being Simultaneously Curious and Stressed, Precipitants to Methamphetamine Initiation Among Chinese Men Who Have Sex With Men: Findings From a Qualitative Study. The Journal of the Association of Nurses in AIDS Care : JANAC, 10.1097/JNC.0000000000000257. Advance online publication.

Abstract: 

The cultural context and precipitants for initiating methamphetamine (MA) using among Chinese men who have sex with men (MSM) are unclear. This qualitative descriptive study, which explores the specific precipitants of MA initiation within a cultural context among MSM in China, was conducted with data from semistructured, face-to-face interviews with 24 MA-using MSM (8 HIV positive). Two themes were identified, internal precipitants included the following: (a) curiosity, (b) desire for maximum sexual pleasure, (c) experience with other drugs, and (d) strong sense of self-control capacity. External precipitants included (a) Xiao (filial piety), (b) peer pressure, (c) negative life events, (d) parental emotional neglect, and (e) experiences of homophobia. Internal precipitants to MA initiation for Chinese MSM are consistent with past research. External precipitants were more culture specific. This exacerbates the vulnerability of MSM to MA initiation and keeps it hidden among this population. Future drug use prevention interventions for MSM should address external precipitants and integrate culture-specific strategies.

Brief Report: HIV-1 Seroconversion Is Not Associated With Prolonged Rectal Mucosal Inflammation. Journal of acquired immune deficiency syndromes (1999)86(5), e134–e138.

Abstract: 

Objective: Determine the impact of HIV-1 seroconversion on inflammatory cytokines in the rectal mucosa.

Setting: Secondary analysis of data from men who have sex with men and transgender women who participated in a HIV prevention trial Lima, Peru.

Methods: From July to December 2017, 605 men who have sex with men and transgender women were screened for rectal gonorrhea/chlamydia (GC/CT). Fifty GC/CT-positive cases were randomly selected and matched with 52 GC/CT-negative controls by age and number of receptive anal intercourse partners in the last month. All participants were HIV-negative at baseline and those with GC/CT at baseline and/or follow-up received appropriate antibiotic therapy. Participants underwent sponge collection of rectal secretions for the measurement of inflammatory cytokines (IL-1β, IL-6, IL-8, and TNF-α) and were screened for rectal GC/CT and HIV at baseline, 3 months, and 6 months. Wilcoxon rank-sum tests compared inflammatory cytokine levels between participants diagnosed with HIV during follow-up and persons who remained HIV-negative.

Results: Eight participants were diagnosed with HIV at the 3-month (n = 6) or 6-month (n = 2) visit. The median number of receptive anal intercourse partners in the month before HIV diagnosis was the same for those who acquired HIV and those who did not. There were no significant differences in inflammatory cytokine levels in rectal mucosa between participants who did and did not experience HIV seroconversion at any time point.

Conclusions: Despite a surge in viral replication during acute infection, findings from this study suggest that there is no prolonged effect of HIV-1 seroconversion on inflammatory cytokine levels in the rectal mucosa.

Abstract: 

The opioid epidemic is one of the greatest public health problems that the USA faces. Opioid overdose death rates have increased steadily for more than a decade and doubled in 2013-17, as the highly potent synthetic opioid fentanyl entered the drug supply. Demographics of new HIV diagnoses among people who inject drugs are also changing, with more new HIV diagnoses occurring among White people, young people (aged 13-34 years), and people who reside outside large central metropolitan areas. Racial differences also exist in syringe sharing, which decreased among Black people and Hispanic people but remained unchanged among White people in 2005-15. Recent HIV outbreaks have occurred in rural areas of the USA, as well as among marginalised people in urban areas with robust HIV prevention and treatment services (eg, Seattle, WA). Multiple evidence-based interventions can effectively treat opioid use disorder and prevent HIV acquisition. However, considerable barriers exist precluding delivery of these solutions to many people who inject drugs. If the USA is serious about HIV prevention among this group, stigma must be eliminated, discriminatory policies must change, and comprehensive health care must be accessible to all. Finally, root causes of the opioid epidemic such as hopelessness need to be identified and addressed.

Abstract: 

Background: Substance use decreases the likelihood of achieving undetectable HIV viremia; however, the comparative effects by drug have not been fully described. In this study, we compare the effects of methamphetamine use versus other drugs on viremia in sexual minority men on antiretroviral therapy (ART).

Methods: HIV-positive participants currently on ART (N = 230) were selected from an ongoing cohort of diverse young sexual minority men (mSTUDY) enrolled from August 2014 to May 2018. Substance use and sociodemographic factors associated with viremia outcomes were assessed using ordinal regression analysis with generalized estimating equations. Viremia outcomes were grouped as undetectable (<20 copies/mL), low level suppressed (21-200 copies/mL), or not suppressed (>200 copies/mL).

Results: The prevalence of drug use across 825 study visits was 73 %, with methamphetamine use most prevalent (50 %). After adjusting for unstable housing and ART adherence, methamphetamine use, either alone (adjusted OR = 1.87; 95 % CI 1.03-3.40) or with other drugs (adjusted OR = 1.82; 95 % CI 1.12-2.95), was associated with higher odds of increasing viremia compared to no drug use. Other drug use excluding methamphetamine did not show a similar association (adjusted OR = 1.29; 95 % CI 0.80-2.09). Among our study population, nearly half the instances of viremia could be reduced if methamphetamine was discontinued (attributable fraction = 46 %; 95 % CI 3-71 %).

Conclusions: Methamphetamine use, either alone or in combination with other drugs, is associated with failure of viral suppression among sexual minority men on ART independent of adherence and sociodemographic factors. This accounts for nearly half of the observed instances of unsuppressed viremia in this study.

Abstract: 

For men who have sex with men (MSM) in the US, the positive and negative aspects of social capital – access to resources within their social networks and experiences of homophobia – may explain their disproportionate burden of HIV infection. We analyzed data from 379 HIV seronegative and seropositive MSM in Los Angeles, collected between May 2017 and February 2018. Dependent variables were HIV transmission risk behaviors and care continuum outcomes. We used multivariable logistic regression to estimate the association between social capital resources and experiences of homophobia with dependent variables, adjusting for sociodemographics and drug use. Most participants were under age 40 and 41% identified as Black/African American and 36% as Hispanic/Latino. Social capital resources associated with likelihood of new sexually transmitted infections (-5.5% per standard deviation (SD), 95%CI -10.3, 0.7%) and HIV testing (5% per SD, 95%CI 0.8, 9.2%). Experiences of homophobia associated with likelihood of methamphetamine use during sex (10% per SD, 95%CI 7, 14%), receiving (4.3% per SD, 95%CI 1.9, 6.7%) and giving (7.2% per SD, 95%CI 4.5, 9.9%) exchange sex, and missing appointments (7.2% per SD, 95%CI 0.8, 13.6%). Findings that social capital associated with HIV transmission risk behaviors and HIV testing suggest interventions to increase social capital resources would impact the HIV-prevention continuum.

Abstract:

Associations between substance use disorders and outbreaks of HIV and acute viral hepatitis have received considerable attention, but less research has focused on links between substance use disorders and sexually transmitted infections, apart from alcohol misuse. This narrative review describes the history of this public health crisis in the United States and direct and indirect effects opioids and specific stimulants have on high-risk sexual behaviors. We also review the epidemiology of sexually transmitted infections associated with opioids and stimulants in the United States and discuss opportunities for integrated interventions.

This narrative review describes the relationship between the US opioid epidemic, its relationship to the epidemiology of sexually transmitted infections, and opportunities for integrated interventions.

Abstract:

Objective: The COVID-19 pandemic has dramatically impacted mental health, increasing rates of substance misuse. Resilience is a positive adaptation to stress that may act as a buffer against adverse mental health outcomes. Based on prior knowledge, we hypothesized that PLWH would display higher resilience than HIV-uninfected peers, and that high resilience would be associated with lower risk of substance misuse.

Methods: This analysis of the Collaborating Consortium of Cohorts Producing NIDA Opportunities (C3PNO) included data from six USA cohorts that administered a COVID-19-related survey with a 3-month follow-up during May 2020 and March 2021. All data was self-reported. The Brief Resilience Scale and General Anxiety Disorder-7 were utilized. Primary analyses consisted of multivariate generalized linear mixed models with random intercepts using binary logistic regression.

Results: A total of 1430 participants completed both surveys, of whom 670 (46.9%) were PLWH. PLWH had lower odds of anxiety (OR=0.67, 95% CI: 0.51–0.89) and higher odds of high resilience (OR=1.21, 95% CI: 1.02–1.44) than HIV-uninfected participants, adjusted for covariates. The presence of anxiety was associated with higher risk of misuse of all substances. High resilience was associated with lower risk of anxiety and misuse of substances, adjusted for covariates.

Conclusions: Psychological resilience was associated with lower risk of anxiety and substance misuse, potentially serving as a buffer against poor mental and behavioral health during the COVID-19 pandemic. Further research is needed to identify pathways of resilience in the context of substance misuse and comprehensive resilience-focused interventions.

Okafor CN, Li MJ, Hucks-Ortiz C, Mayer KH, Shoptaw S. Disclosure of HIV status and HIV sexual transmission behaviors among HIV-positive black men who have sex with men in the BROTHERS (HPTN 061) study. Journal of Urban Health. 2020 Feb 4:1-2.

Abstract:

We assessed whether disclosure of HIV status is significantly associated with reported HIV sexual risk behaviors among HIV positive Black/African American men who have sex with men (MSM) (Black MSM) in six cities in the USA. Participants from the BROTHERS (HIV Prevention Trials Network [HPTN 061]) study focused on assessing the feasibility and acceptability of a multifaceted HIV prevention intervention to reduce HIV infections among Black MSM enrolled between July 2009 and October 2010. All participants completed a behavioral assessment using an audio computer-assisted self-interview that included questions about HIV status disclosure, HIV sexual risk behaviors, and other behaviors. Biological samples were also collected. This analysis focused on baseline data of HIV-positive Black MSM in the HPTN 061 study. Of the 143 HIV-positive Black MSM (majority ≥ 35 years of age) included in this analysis, 58% reported disclosing their HIV status to their last male anal sex partner. Forty-three percent and 42% reported condomless insertive and receptive anal intercourse respectively with their last male partner; whereas, 17% and 18% of the sample engaged in condomless insertive and receptive anal intercourse with a serodiscordant/unknown status partner, respectively. In multivariable logistic regression models, there was no statistically significant association between HIV status disclosure and condomless insertive anal intercourse (aOR = 0.35, 95% CI 0.11, 1.08; p = 0.30), condomless receptive anal intercourse (aOR = 2.48, 95% CI 0.94, 6.52; p = 0.20), or condomless receptive anal intercourse with a serodiscordant/unknown status partner (aOR = 0.55, 95% CI 0.20, 1.49; p = 0.45). However, HIV status disclosure was significantly associated with lower odds of reporting condomless insertive anal intercourse with a serodiscordant/unknown status partner (aOR = 0.19, 95% CI 0.06, 0.68; p ≤ 0.01). Among this multi-city sample of HIV-positive Black MSM, disclosure of HIV status was common and associated with lower HIV sexual risk behaviors. These findings should motivate and guide research to develop prevention messages to increase HIV status disclosures.

Abstract:

Background: In March of 2013, the Los Angeles County (LAC) Division of HIV and STD Programs implemented a clinic-based Medical Care Coordination (MCC) Program to increase viral suppression (VS) (<200 c/mL) among people living with HIV (PLWH) at high risk for poor health outcomes.

Objective: This study aimed to estimate trajectories of VS and to assess whether these trajectories differed by stimulant use, housing instability, and depressive symptom severity as reported by PLWH participating in MCC.

Methods: Data represent 6408 PLWH in LAC receiving services from the MCC Program and were obtained from LAC HIV surveillance data matched to behavioral assessments obtained across 35 Ryan White Program clinics participating in MCC. Piecewise mixed-effects logistic regression with a random intercept estimated probabilities of VS from 12 months before MCC enrollment through 36 months after enrollment, accounting for time by covariate interactions for 3 comorbid conditions: housing instability, stimulant use, and depressive symptoms.

Results: The overall probability of VS increased from 0.35 to 0.77 within the first 6 months in the MCC Program, and this probability was maintained up to 36 months after enrollment. Those who reported housing instability, stimulant use, or multiple comorbid conditions did not achieve the same probability of VS by 36 months as those with none of those comorbidities.

Conclusions: Findings suggest that MCC improved the probability of VS for all patient groups regardless of the presence of comorbidities. However, those with comorbid conditions will still require increased support from patient-centered programs to address disparities in VS.

Lake MT, Shoptaw S, Ipser JC, Takada S, van Nunen LJ, Lipinska G, Stein DJ, London ED. Decision-Making by Patients With Methamphetamine Use Disorder Receiving Contingency Management Treatment: Magnitude and Frequency Effects. Frontiers in psychiatry. 2020 Feb 18;11:22.

Abstract:

Background: Individuals with substance use disorders exhibit maladaptive decision-making on the Iowa Gambling Task (IGT), which involves selecting from card decks differing in the magnitudes of rewards, and the frequency and magnitude of losses. We investigated whether baseline IGT performance could predict responses to contingency management (CM) by treatment-seeking individuals with methamphetamine use disorder (MA Use Disorder) in Cape Town, South Africa.

Methods: Twenty-nine individuals with MA Use Disorder underwent an 8-week, escalating reinforcement, voucher-based CM treatment in a study on the suitability of CM therapy for the South African context. Along with 20 healthy control participants, they performed a computerized version of the IGT before starting CM treatment. Seventeen participants maintained abstinence from methamphetamine throughout the trial (full responders), and 12 had an incomplete response (partial responders). Performance on the IGT was scored for magnitude effect (selection of large immediate rewards with high long-term loss) and for frequency effect (preference for frequent rewards and avoidance of frequent losses). Group differences were investigated using linear mixed-effect modeling.

Results: Partial responders made more selections from decks providing large, immediate rewards and long-term losses than healthy controls [p = 0.038, g = -0.77 (-1.09: -0.44)]. Full responders showed a greater, nonsignificant preference for frequent rewards and aversion to frequent losses than partial responders [p = 0.054, g = -0.63 (-0.95: -0.29)].

Conclusions: A predilection for choices based on the size and immediacy of reward may reflect a cognitive strategy that works against CM. Pretesting with a decision-making task, such as the IGT, may help in matching cognitive therapies to clients with MA Use Disorder.

Emerging evidence from a systematic review of safety of pre‐exposure prophylaxis for pregnant and postpartum women: where are we now and where are we heading?. Journal of the International AIDS Society. 2020 Jan;23(1):e25426.

Abstract:

Introduction: HIV incidence is high during pregnancy and breastfeeding with HIV acquisition risk more than doubling during pregnancy and the postpartum period compared to when women are not pregnant. The World Health Organization recommends offering pre-exposure prophylaxis (PrEP) to pregnant and postpartum women at substantial risk of HIV infection. However, maternal PrEP national guidelines differ and most countries with high maternal HIV incidence are not offering PrEP. We conducted a systematic review of recent research on PrEP safety in pregnancy to inform national policy and rollout.

Methods: We used a standard Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) approach to conduct a systematic review by searching for completed, ongoing, or planned PrEP in pregnancy projects or studies from clinicaltrials.gov, PubMed and NIH RePORTER from 2014 to March 2019. We performed a systematic review of studies that assess tenofovir disoproxil fumarate (TDF)-based oral PrEP safety in pregnant and breastfeeding HIV-uninfected women.

Results and discussion: We identified 14 completed (n = 5) and ongoing/planned (n = 9) studies that evaluate maternal and/or infant outcomes following PrEP exposure during pregnancy or breastfeeding. None of the completed studies found differences in pregnancy or perinatal outcomes associated with PrEP exposure. Nine ongoing studies, to be completed by 2022, will provide data on >6200 additional PrEP-exposed pregnancies and assess perinatal, infant growth and bone health outcomes, expanding by sixfold the data on PrEP safety in pregnancy. Research gaps include limited data on (1) accurately measured PrEP exposure within maternal and infant populations including drug levels needed for maternal protection; (2) uncommon perinatal outcomes (e.g. congenital anomalies); (3) infant outcomes such as bone growth beyond one year following PrEP exposure; (4) outcomes in HIV-uninfected women who use PrEP during pregnancy and/or lactation.

Conclusions: Expanding delivery of PrEP is an essential strategy to reduce HIV incidence in pregnancy and breastfeeding women. Early safety studies of PrEP among pregnant women without HIV infection are reassuring and ongoing/planned studies will contribute extensive new data to bolster the safety profile of PrEP use in pregnancy. However, addressing research gaps is essential to expanding PrEP delivery for women in the context of pregnancy.

Abstract:

AimsMethamphetamine Use Disorder is prevalent in South Africa. This analysis uses data from a contingency management (CM) pilot study in South Africa to replicate and expand on a U.S.-based study showing that CM voucher spending was associated with drug abstinence behavior.

DesignParticipants with methamphetamine-use disorder were enrolled in an 8-week CM trial requiring thrice weekly visits and received cash vouchers in exchange for stimulant-negative urines at each visit.

ParticipantsParticipants were 33 treatment-seeking individuals with methamphetamine use disorder including 22 men (66.7%) and 11 women (33.3%) with a mean age of 34 years (S.D. = 7.7). Participants reported using methamphetamine for a mean of 11.7 years (S.D. = 4.9).

SettingAll study procedures took place in South Africa between August 2016 and May 2018.

MeasurementsA time-lagged counting process Cox Proportional Hazards model for recurrent event survival analysis examined the relationship between frequency of and participant-categorized type of CM expenditures (hedonic, utilitarian, consumable or durable) and drug abstinence.

FindingsAfter controlling for severity of baseline methamphetamine use and accumulated CM earnings (proxied by cumulative negative urines), those spending CM earnings at a previous visit (“spenders”) were more likely to produce stimulant-negative urine samples subsequently, compared to those who did not (“savers”) [OR = 1.23, CI = 1.08-1.53, p = .002]. There were significantly more cumulative stimulant-negative results among spenders vs. savers, p < .001, although cumulative spending did not significantly predict abstinence once spending in the prior time period was controlled for, suggesting a recency effect tied to the underlying spending mechanism. When extending the original analyses to look at the effect of spending on current abstinence, controlling only for recent abstinence (rather than cumulative abstinence), spending was no longer a significant predictor. Spending type did not affect methamphetamine abstinence. Qualitative results suggest spending CM vouchers may support social reintegration over the course of the trial.

ConclusionsAbstinence outcomes are a function of CM spending in both the U.S. and South Africa. Findings of a significant relationship between contingency management spending and subsequent stimulant-negative urine samples across geographic locations provide guidance toward future work in optimizing CM efficacy.

Li MJ, Briones MS, Heinzerling KG, Kalmin MM, Shoptaw SJ. Ibudilast attenuates peripheral inflammatory effects of methamphetamine in patients with methamphetamine use disorder. Drug and Alcohol Dependence. 2020 Jan 1;206:107776.

Abstract
Background: Preclinical studies suggest that the non-selective phosphodiesterase inhibitor, Ibudilast (IBUD) may contribute to the treatment of methamphetamine (METH) use disorder through the attenuation of METH-induced inflammatory markers such as adhesion molecules, sICAM-1 and sVCAM-1, and cytokines, IL-6 and TNF-α.

Objective: The present study aimed to test whether treatment with IBUD can attenuate peripheral markers of inflammation during a METH challenge in an inpatient clinical trial of 11 patients.

Methods: This trial followed a randomized, within-subjects crossover design where participants received a METH challenge, during which five participants were treated with placebo then with IBUD, while the remaining six participants were treated with IBUD prior to placebo. Mixed effects regression modeled changes in peripheral markers of inflammation-sICAM-1, sVCAM-1, TNF-α, IL-6, MIF, and cathepsin D-by treatment condition, with measurements at baseline, 60 min post-METH infusion, and 360 min post-METH infusion.

Results: While on placebo, sICAM-1, sVCAM-1, and cathepsin D significantly increased by 60 min post-METH infusion, while IL-6 significantly increased 360 min post-METH infusion. Treatment with IBUD significantly reduced METH-induced levels of sICAM-1, sVCAM-1, and cathepsin D at 60 min post-METH infusion.

Conclusions: Our findings demonstrate that IBUD attenuated acute pro-inflammatory effects of METH administration, which may have implications for treatment of METH use disorder.

Abstract
Introduction and Aims
As South Africa, especially the Western Cape Province, faces an epidemic of methamphetamine use disorder, therapeutic approaches suited to the South African context are needed. This secondary analysis assessed retention and methamphetamine abstinence outcomes in response to an 8‐week pilot contingency management (CM) intervention trial of neural correlates of methamphetamine abstinence, exploring sociodemographic and clinical differences between responders and non‐responders.

Design and Methods
Research participants provided thrice‐weekly monitored urine samples, which were analysed by qualitative radioimmunoassay. The primary outcome for this analysis was therapeutic response, defined as abstinence from methamphetamine (≥23 of 24 possible methamphetamine‐negative urine samples).

Results
Data from 30 adults living in Cape Town, South Africa (34 ± 6.1 years of age, mean age ± SD, 21 men) were included. Sixty‐three percent (12 men) were responders. In bivariate comparisons, baseline measurements showed fewer responders reported monthly household income ≥25 000+ South African Rand (ZAR; ~USD $1880; vs. ZAR < 25 000) than non‐responders (15.8% vs. 63.6%; P = 0.007). Furthermore, responders had higher median years of education (12 vs. 10; Kruskal–Wallis χ2 = 4.25, DF = 1, P = 0.039) and lower median body mass index than non‐responders (19 vs. 24; Kruskal–Wallis χ2 = 6.84, P = 0.008).

Discussion and Conclusions
Therapeutic response in this study were comparable to those obtained with CM for methamphetamine use disorder in North America and Europe. Our findings suggest that CM may be a useful component of treatment strategies to boost retention and continuous abstinence from methamphetamine in Cape Town, South Africa. Larger efficacy studies are needed in this setting.

Quinn B, Gorbach PM, Okafor CN, Heinzerling KG, Shoptaw S. Investigating possible syndemic relationships between structural and drug use factors, sexual HIV transmission and viral load among men of colour who have sex with men in Los Angeles County. Drug and alcohol review. 2020 Feb;39(2):116-27.

Abstract:

Introduction and aims: Past research investigating syndemic factors and HIV-related outcomes has overlooked the impact of structural conditions on behaviours linked with HIV transmission and disease progression. Given prevalent substance use among our sample, we explored whether four structural conditions indicative of social marginalisation and previously correlated with increased risk for HIV infection demonstrated syndemic (additive/synergistic) effects on: (i) HIV viral suppression; and (ii) self-reported involvement in sexual HIV transmission behaviours among a prospective cohort mostly comprising men of colour who have sex with men (MCSM; i.e. Latino/Hispanic and African American/black men) in Los Angeles County.

Design and methods: Data were collected between August 2014 and March 2017. The structural conditions of interest were: current unemployment, recent (≤6 months) incarceration history, ‘unstable’ accommodation (past month) and remote (>6 months) contact with health-care providers. Generalised estimating equations assessed possible additive effects of experiencing multiple structural conditions, and possible synergistic effects on the HIV-related outcomes.

Results: Of 428 participants, nearly half (49%) were HIV-positive at baseline. Involvement in sexual HIV transmission risk behaviours varied over follow-up (22-30%). Reporting ≥2 structural syndemic conditions was significantly associated with reporting sexual HIV transmission risk behaviours among HIV-negative participants, and detectable viral load among HIV-positive participants. Frequent methamphetamine use was consistently associated with the HIV-related outcomes across the final multivariate models.

Discussion and conclusions: When developing initiatives to address HIV transmission among marginalised sub-populations including MCSM, we must holistically consider systemic and structural issues (e.g. unemployment and homelessness), especially in the context of prevalent substance use.

Abstract:

Introduction: Marijuana use is common among persons living with HIV, but whether it’s use increases the risk of type 2 diabetes in this population has not been explored.

Objective: To determine whether self-reported marijuana use is associated with incident type 2 diabetes in women and men living with and at risk for HIV.

Methods: We analyzed data from the Women’s Interagency HIV Study (WIHS) and Multicenter AIDS Cohort Study (MACS), between 2000-2017 (WIHS) and 1999-2017 MACS. The association between self-reported marijuana use and incident type 2 diabetes was analyzed using time-dependent Cox regression models among 3578 and 2682 participants in the WIHS and MACS respectively.

Results: Over the follow-up period, 452 (WIHS) and 326 (MACS) incident type 2 diabetes cases occurred. In multivariable models, the hazard ratios, collectively indicate a reduced risk of type 2 diabetes, in marijuana users compared to none users, although all associations were not statistically significant. The results were similar for HIV-positive and HIV-negative participants in both cohorts.

Conclusions: In this prospective analysis of nearly 20 years of data for women and men with and at risk for HIV in the WIHS and MACS, although we found a pattern of reduced risk of type 2 diabetes among self-reported marijuana users, the associations were not statistically significant. To better inform clinical decisions and legal policy regarding marijuana use in this population, further longitudinal investigations that biologically quantify marijuana use to assess risk for incident diabetes is warranted.

Abstract:

Background: The HIV epidemic in the USA is a collection of diverse local microepidemics. We aimed to identify optimal combination implementation strategies of evidence-based interventions to reach 90% reduction of incidence in 10 years, in six US cities that comprise 24·1% of people living with HIV in the USA.

Methods: In this economic modelling study, we used a dynamic HIV transmission model calibrated with the best available evidence on epidemiological and structural conditions for six US cities: Atlanta (GA), Baltimore (MD), Los Angeles (CA), Miami (FL), New York City (NY), and Seattle (WA). We assessed 23 040 combinations of 16 evidence-based interventions (ie, HIV prevention, testing, treatment, engagement, and re-engagement) to identify combination strategies providing the greatest health benefit while remaining cost-effective. Main outcomes included averted HIV infections, quality-adjusted life-years (QALYs), total cost (in 2018 US$), and incremental cost-effectiveness ratio (ICER; from the health-care sector perspective, 3% annual discount rate). Interventions were implemented at previously documented and ideal (90% coverage or adoption) scale-up, and sustained from 2020 to 2030, with outcomes evaluated until 2040.

Findings: Optimal combination strategies providing health benefit and cost-effectiveness contained between nine (Seattle) and 13 (Miami) individual interventions. If implemented at previously documented scale-up, these strategies could reduce incidence by between 30·7% (95% credible interval 19·1-43·7; Seattle) and 50·1% (41·5-58·0; New York City) by 2030, at ICERs ranging from cost-saving in Atlanta, Baltimore, and Miami, to $95 416 per QALY in Seattle. Incidence reductions reached between 39·5% (26·3-53·8) in Seattle and 83·6% (70·8-87·0) in Baltimore at ideal implementation. Total costs of implementing strategies across the cities at previously documented scale-up reached $559 million per year in 2024; however, costs were offset by long-term reductions in new infections and delayed disease progression, with Atlanta, Baltimore, and Miami projecting cost savings over the 20 year study period.

Interpretation: Evidence-based interventions can deliver substantial public health and economic value; however, complementary strategies to overcome social and structural barriers to HIV care will be required to reach national targets of the ending the HIV epidemic initiative by 2030.

Clinical Infectious Diseases. 2020 Dec 1;71(11):2968-71.

Abstract:

We estimated human immunodeficiency virus incidence and incidence rate ratios (IRRs) for black and Hispanic vs white populations in 6 cities in the United States (2020-2030). Large reductions in incidence are possible, but without elimination of disparities in healthcare access, we found that wide disparities persisted for black compared with white populations in particular (lowest IRR, 1.69 [95% credible interval, 1.19-2.30]).

Abstract:

Psychometric data linking of psychological and behavioral questionnaires can facilitate the harmonization of data across HIV and substance use cohorts. Using data from the Collaborating Consortium of Cohorts Producing NIDA Opportunities (C3PNO), we demonstrate how to capitalize on previous linking work with a common linked depression metric across multiple questionnaires. Cohorts were young men who have sex with men (MSM), substance-using MSM, HIV/HCV cocaine users, and HIV-positive patients. We tested for differential item functioning (DIF) by comparing C3PNO cohort data with general population data. We also fit a mixed-effects model for depression, entering HIV-status and recent opioid/heroin use as fixed effects and cohort as a random intercept. Our results suggest a minimal level of DIF between the C3PNO cohorts and general population samples. After linking, descriptive statistics show a wide range of depression score means across cohorts. Our model confirmed an expected positive relationship between substance use and depression, though contrary to expectations, no significant association with HIV status. The study reveals the likely role of cohort differences, associated patient characteristics, study designs, and administration settings.

Brief report: Associations between self-reported substance use behaviors and PrEP acceptance and adherence among black MSM in the HPTN 073 study. JAIDS Journal of Acquired Immune Deficiency Syndromes. 2020 Sep 1;85(1):23-9.

Abstract:

Background: Pre-exposure prophylaxis (PrEP) is efficacious for HIV prevention. Black men who have sex with men (MSM) accounted for the largest proportion of new HIV diagnoses in the United States relative to other racial/ethnic groups. Black MSM who use substances are at an increased risk for HIV infection and are ideal candidates for PrEP, but barriers to maintaining PrEP adherence remain a concern. We assessed whether substance use behaviors are associated with initiation and adherence to PrEP among a sample of black MSM in the United States.

Methods: Data for this analysis come from the HIV Prevention Trails Network Study 073 (HPTN 073). Substance use behaviors-including alcohol, marijuana, poppers (ie, alkyl nitrites), and stimulants (ie, methamphetamine/cocaine use) including use of these substances before/during condomless anal intercourse (CAI)-were assessed longitudinally through self-report. PrEP adherence was assessed by pharmacological testing in blood. Generalized estimating equations were used to evaluate association between substance use behaviors and PrEP initiation and adherence.

Results: Among 226 HIV-negative black MSM, the majority (60%) were 25+ years of age. Most of the substance use behaviors were not significantly associated with PrEP initiation or adherence. However, stimulant use before/during CAI was significantly associated with lower odds of PrEP adherence (adjusted odds ratio = 0.21, 95% confidence interval = 0.07 to 0.61; P = <0.01).

Conclusions: These findings suggest that PrEP adherence is feasible among black MSM who use substances. However, black MSM who engage in stimulant use before/during CAI may present a unique group for additional study and support with enhanced behavioral health and support services.

Defining gaps in pre-exposure prophylaxis delivery for pregnant and post-partum women in high-burden settings using an implementation science framework. The lancet HIV. 2020 Aug 1;7(8):e582-92.

Abstract:

Pregnancy is a high-risk period for HIV acquisition in African women, and pregnant women who become acutely infected with HIV account for up to a third of vertical HIV transmission cases in African settings. To protect women and eliminate vertical transmission, WHO recommends offering oral pre-exposure prophylaxis (PrEP) based on tenofovir to HIV-negative pregnant and post-partum women with a substantial risk of HIV acquisition. PrEP implementation for pregnant and post-partum women lags behind implementation for other high-risk populations. Unique considerations for PrEP implementation arise during pregnancy and post partum, including the integration of provider training with clinical delivery and monitoring of PrEP exposure and outcomes within existing maternal health systems, yet scarce implementation data are available to generate evidence in this context.

Blair CS, Javanbakht M, Comulada WS, Richter EI, Bolan R, Shoptaw S, Gorbach PM. Lubricants and rectal douching: associations with rectal gonorrhea, chlamydia, and/or syphilis infection among men who have sex with men. International journal of STD & AIDS. 2020 Oct;31(11):1040-6.

Abstract:

Despite widespread prevalence of lubricant use and rectal douching for receptive anal intercourse (RAI) among men who have sex with men (MSM), research evaluating the association of these behaviors with sexually transmitted infections (STIs) is limited. This is an observational analysis of a longitudinal cohort of predominantly Black/Latino MSM in Los Angeles. Every six months from August 2014 to January 2018, participants received STI screening and surveys evaluating lubricant use, douching, substance use, and sexual risk behaviors. General estimating equations evaluated the association between consistent lubricant use and douching for RAI with positive rectal Neisseria gonorrhoeaeChlamydia trachomatis, and/or syphilis (positive STI). Among 313 participants across 552 study visits, 16.5% (91/552) had positive STI. Consistent lubricant use was reported in 52.7% (243/552) and rectal douching in 57.6% (318/552) of study visits. Consistent lubricant use was associated with STI diagnosis (adjusted OR [AOR] 1.81; 95% CI 1.11-2.96; p = 0.018). Each episode of rectal douching before RAI was associated with 2% increased odds of positive STI (AOR 1.02; 95% CI 1.00-1.04; p = 0.041). Among this cohort of HIV-positive and high-risk HIV-negative MSM, lubricant use and douching was common and independently associated with an STI, suggesting the utility of prevention messaging around barrier methods/condoms for sexual encounters involving douching/lubricant use.

Abstract:

Background: Prevalence of methamphetamine (meth) injection and associated human immunodeficiency virus (HIV) risks among men who have sex with men (MSM) are unclear.

Methods: A total of 532 MSM completed 1880 mSTUDY study visits between August 2014 and June 2018 in Los Angeles, California. Assessments every 6 months included computer-assisted self-interviews and testing for sexually transmitted infections. Analyses by person and across visits adjusted for repeated measures.

Results: Of 532 participants, 51% (n = 276) reported meth use (past 6 months). Across 1880 visits, mutually exclusive substance use categories were as follows: 5% meth injection (5%), meth use without injection (33%), other substance use excluding meth (36%), and no substance use (26%). Comparisons across these categories respectively found that meth injectors reported higher prevalence of new sex partners (89%, 70%, 68%, and 51%, respectively), more were HIV positive (83%, 65%, 34%, and 50%), fewer were virally suppressed (53%, 48%, 61%, and 67%), and more had sexually transmitted infections (31%, 22%, 15%, and 15% (all P <.01).

Conclusions: Among the young MSM reporting meth injection in this Los Angeles cohort, elevated risks of acquiring or transmitting HIV suggest that they contribute significantly to sustaining the local HIV epidemic. Preventing transition to injection use has potential for HIV prevention.

Psychometric properties of measures of substance use: a systematic review and meta-analysis of reliability, validity and diagnostic test accuracy. BMC medical research methodology. 2020 Dec;20:1-22.

Abstract:

Background: Synthesis of psychometric properties of substance use measures to identify patterns of use and substance use disorders remains limited. To address this gap, we sought to systematically evaluate the psychometric properties of measures to detect substance use and misuse.

Methods: We conducted a systematic review and meta-analysis of literature on measures of substance classes associated with HIV risk (heroin, methamphetamine, cocaine, ecstasy, alcohol) that were published in English before June 2016 that reported at least one of the following psychometric outcomes of interest: internal consistency (alpha), test-retest/inter-rater reliability (kappa), sensitivity, specificity, positive predictive value, and negative predictive value. We used meta-analytic techniques to generate pooled summary estimates for these outcomes using random effects and hierarchical logistic regression models.

Results: Findings across 387 paper revealed that overall, 65% of pooled estimates for alpha were in the range of fair-to-excellent; 44% of estimates for kappa were in the range of fair-to-excellent. In addition, 69, 97, 37 and 96% of pooled estimates for sensitivity, specificity, positive predictive value, and negative predictive value, respectively, were in the range of moderate-to-excellent.

Conclusion: We conclude that many substance use measures had pooled summary estimates that were at the fair/moderate-to-excellent range across different psychometric outcomes. Most scales were conducted in English, within the United States, highlighting the need to test and validate these measures in more diverse settings. Additionally, the majority of studies had high risk of bias, indicating a need for more studies with higher methodological quality.

Hermanstyne KA, Green HD, Tieu HV, Hucks-Ortiz C, Wilton L, Shoptaw S. The association between condomless anal sex and social support among black men who have sex with men (MSM) in six US cities: A study using data from the HIV prevention trials network BROTHERS study (HPTN 061). AIDS and Behavior. 2019 Jun;23(6):1387-95.

Abstract:

We assessed how egocentric (i.e., self-generated descriptions of a person’s social contacts) network structure and composition corresponded with reported instances of condomless receptive and insertive anal intercourse with men who were reportedly HIV-infected or of unknown HIV serostatus in a sample of black men who have sex with men (MSM) in six U.S. cities. Ratings showing a higher percentage of network members who provided social participation and medical support were positively associated with reporting condomless sex. There were also significant positive associations between stimulant use and condomless insertive and receptive anal sex. Future research should examine the social processes that underlie these associations and explore ways that social support can affect HIV prevention efforts for black MSM.

Rectal microbiome alterations associated with oral human immunodeficiency virus pre-exposure prophylaxis. InOpen forum infectious diseases 2019 Nov (Vol. 6, No. 11, p. ofz463). US: Oxford University Press.

Abstract:

Background: Oral daily tenofovir (TFV) disoproxil fumarate/emtricitabine (TDF/FTC) for human immunodeficiency virus (HIV) pre-exposure prophylaxis (PrEP) is highly effective for HIVprevention, yet long-term effects are not fully understood. We investigated the effects of PrEP on the rectal microbiome in a cohort of men who have sex with men (MSM).

Methods: This cross-sectional analysis included HIV-negative MSM either on PrEP (n = 37) or not (n = 37) selected from an ongoing cohort using propensity score matching. Rectal swabs were used to examine microbiome composition using 16S ribosomal ribonucleic acid gene sequencing, and associations between PrEP use and microbiota abundance were examined. Hair specimens were used to quantify TFV and FTC exposure over the past 6 weeks on a subset of participants (n = 15).

Results: Pre-exposure prophylaxis use was associated with a significant increase in Streptococcus abundance (adjusted P = .015). Similar associations were identified using least absolute shrinkage and selection operator (LASSO) regression, confirming the increase in Streptococcus and also showing increased MitsuokellaFusobacterium, and decreased Escherichia/Shigella. Increased Fusobacterium was significantly associated with increasing TFV exposure.

Conclusions: Oral TDF/FTC for PrEP is associated with rectal microbiome changes compared to well matched controls, specifically increased Streptococcus and Fusobacterium abundance. This study highlights the need for future investigations of the role of microbiome changes on HIV susceptibility and effectiveness of PrEP.

The intersection of HIV, social vulnerability, and reproductive health: analysis of women living with HIV in Rio de Janeiro, Brazil from 1996 to 2016. AIDS and Behavior. 2019 Jun;23(6):1541-51.

Abstract:

Comprehensive care for sexual and reproductive health (SRH) and social needs for women living with HIV remains limited globally. We aimed to assess trends in baseline sociodemographic, clinical, sexual, and reproductive characteristics among a cohort of HIV-infected women in Rio de Janeiro from 1996 to 2016. Participants were stratified into four time periods based on year of enrollment; we compared cross-sectional data from each period. Of 1361 participants (median age 36), most were black or mixed race (60.1%), unemployed (52.1%), and without secondary education (54%). Adolescent pregnancy was common (51.5%), and 18.3% reported sexual debut at < 15 years old. Nearly half (45.2%) had < 5 lifetime sexual partners, yet prior syphilis and oncogenic human papillomavirus prevalence were 10.9% and 43.1%, respectively. Lifetime prevalence of induced abortion was 30.3%, and 16% used no contraceptive method. Future research should explore interactions between social vulnerability, HIV, and poor SRH outcomes and healthcare models to alleviate these disparities.

Sexual network characteristics of men who have sex with men with syphilis and/or gonorrhoea/chlamydia in Lima, Peru: network patterns as roadmaps for STI prevention interventions. Sexually transmitted infections. 2019 Aug 1;95(5):336-41.

Abstract:

Objective: While men who have sex with men (MSM) are disproportionately affected by Peru’s overlapping HIV and STI epidemics, there are few data on how partnership-level and network-level factors affect STI transmission in Peru. We explored partnership-level and network-level factors associated with gonorrhoea/chlamydia (Neisseria gonorrhoeae and/or Chlamydia trachomatis (NG/CT)) and/or syphilis infection among MSM in Peru.

Methods: We present the results of a cross-sectional secondary analysis of MSM (n=898) tested for syphilis and NG/CT infection as part of the screening process for two STI control trials in Lima, Peru. Participants completed questionnaires on demographics, sexual identity and role, characteristics of their three most recent sexual partners (partner sexual orientation, gender, role, partnership type, partner-specific sexual acts) and 30-day sexual network characteristics (number of sexual partners, partnership types, frequency of anal/vaginal intercourse). Participants were tested for syphilis and urethral, rectal and oropharyngeal NG/CT. Differences in network characteristics were analysed with χ2 and Kruskal-Wallis tests.

Results: Approximately 38.9% of participants had a new STI diagnosis (syphilis (rapid plasma reagin ≥16): 10.6%; NG/CT: 22.9%; syphilis-NG/CT coinfection: 5.4%). Condomless anal intercourse (CAI) was not significantly associated with an STI diagnosis. Gay-identified participants with exclusively homosexual networks had a higher prevalence of STIs (47.4%) than gay-identified MSM with only heterosexual/bisexual partners (34.6%, p=0.04), despite reporting fewer sexual partners (any partners: 2, 1-4 vs 3, 2-6; p=0.001; casual partners: 1, 0-3 vs 2, 1-4; p=0.001) and more stable partnerships (1, 0-1 vs 0, 0-1; p=0.003) in the last month.

Conclusions: Network size and the number of casual sexual partners were associated with NG/CT infection among MSM in Peru. Despite reporting fewer sexual risk behaviours (smaller network size, more stable partnerships, less CAI), MSM with homosexual-only sexual networks had a higher prevalence of NG/CT and syphilis. These findings suggest network composition among MSM in Peru plays an important role in the risk for STI acquisition.

Molina Y, Ulrich A, Greer AC, Primbas A, Wandell G, Sanchez H, Bain C, Konda KA, Clark JL, De la Grecca R, Villarán MV. Impact of pre-diagnosis awareness of HIV-related stigma and dispositional coping on linkage to HIV care among newly diagnosed HIV+ Peruvian patients. AIDS care. 2019 Jul 3;31(7):848-56.

Abstract:

A substantial body of literature has characterized how psychosocial factors, including HIV-related stigma and coping, are associated with HIV testing and HIV care utilization post-diagnosis. Less is known about if certain psychosocial characteristics pre-diagnosis may also predict linkage to care among individuals who receive an HIV-positive diagnosis. We examined if pre-diagnosis awareness/perception about HIV-related stigma and dispositional coping styles predicted linkage to HIV care within three months post-diagnosis with a secondary analysis of 604 patients from a randomized controlled trial (Sabes Study). Awareness/perception about HIV-related stigma, dispositional maladaptive and adaptive coping were measured before patients underwent an HIV test. Linkage to care was measured as receipt of care within three months of receiving the diagnosis. After adjusting for covariates, individuals who reported greater dispositional maladaptive coping pre-diagnosis had lower odds of linking to care, OR = 0.82, 95%CI [0.67, 1.00], p = .05. There was also a non-significant inverse association between dispositional adaptive coping pre-diagnosis and linkage to care. These preliminary data suggest the need for further longitudinal research and highlight the potential utility of pre-diagnosis psychosocial assessment and tailored counseling when providing positive HIV diagnosis results.

It is Very Sad to be Alone”: Transnational Practices and the Importance of Family for Mexican and Puerto Rican Latinxs Living with HIV in the Continental US. Journal of Immigrant and Minority Health. 2020 Jun 4:1-9.

Abstract:

Latinxs continue to be overrepresented in the U.S. HIV epidemic. We examined the transnational practices, family relationships, and realities of life of Mexicans and Puerto Ricans living with HIV in the continental U.S. We conducted qualitative interviews with 44 persons of Mexican and Puerto Rican origin participating in HIV care engagement interventions. Framework Analysis guided our data analysis. Among participants, a strong connection to the family was intertwined with transnational practices: communication, travel to their place of origin to maintain family ties, and material and/or emotional support. Separation from their family contributed to social isolation. Many participants lacked emotional support regarding living with HIV. Transnational practices and family relationships were intrinsic to the experiences of Mexicans and Puerto Ricans living with HIV in the continental U.S.; and may help understand the points of reference, health-seeking behaviors, and support sources that influence their health, well-being and engagement in HIV care.

Watson CC, Wilton L, Lucas JP, Bryant L, Victorianne GD, Aradhya K, Fields SD, Wheeler DP, Caucus HB. Development of a black caucus within the HIV prevention trials network (HPTN): representing the perspectives of black men who have sex with men (MSM). International journal of environmental research and public health. 2020 Jan;17(3):871.

Abstract:

Black men who have sex with men (MSM) have disproportionate HIV disease burden in the United States. Black MSM have been underrepresented in biomedical research, including HIV clinical trials, due to a myriad of socio-structural, socio-cultural, and psychosocial factors. The HIV Prevention Trials Network (HPTN) 061, a feasibility study of a multi-component HIV prevention intervention for Black MSM in six US cities, incorporated the development and implementation of a Black Caucus as a culturally grounded model for the integration of Black MSM in clinical trials and research in HPTN. Based on a qualitative methodological approach, we describe the formation and implementation of the Black Caucus from the perspective of Black MSM key community stakeholders. Three major themes emerged from the qualitative narratives: (1) the role of the Black Caucus in shaping the HPTN, (2) how the Black Caucus addresses the needs of Black MSM communities pertaining to the influence of race and sexual identity, and (3) socio-cultural needs of Black MSM. These findings have implications for the provision of culturally congruent expertise, community engagement, cultural mistrust, recruitment and retention of Black MSM in HIV clinical trials, culturally-relevant study design and implementation, and the role of developing Black MSM prevention researchers.

Abstract:

While thirty years of research into an effective cocaine pharmacotherapy has yielded no treatments, knowledge gained doing this work underscores the importance of rigorous clinical design, of attention to medication adherence and of defining endpoints. The field needs a high-risk/high-reward strategy to engineer new compounds that help people to use less cocaine and to preserve gains made during treatment, particularly during lapse/relapse.

Abstract

Accurate HIV risk assessment among men who have sex with men (MSM) is important to help providers assess risk, and target HIV prevention interventions. We sought to develop an evidence-based HIV risk assessment tool for US MSM that is inclusive of Black MSM. Data from four large longitudinal cohorts of MSM were used to develop (EXPLORE), and validate (VAX004, HPTN061, and HVTN505). These data included visits in which participants self-reported HIV risk behavior and underwent HIV testing. We developed a pooled logistic model for incident HIV infection based on self-reported risk behaviors during the 6 months before each study visit. A total of 4069 MSM were used for the development cohort, and 8047 MSM in the three validation cohorts through 2013. The final model includes age (< 35, ≥ 35); Black race and Latino ethnicity; numbers of HIV-negative anal sex partners; number of insertive or receptive anal intercourse episodes; having 1 HIV-negative partner only; self-reported substance use; and bacterial sexually transmitted infection diagnosis. The model showed good discrimination in internal validation (C-statistic = 79.5). The external validation cohorts also showed good discrimination, with C-statistics of 73.1, 71.0, 71.9 in VAX004, HPTN061, and HVTN505 respectively, and acceptable calibration. We developed and validated an HIV risk assessment tool for MSM, which showed good predictive ability, including among the largest cohort of HIV-uninfected Black MSM in the US. This tool is available online (mysexpro.org) and can be used by providers to support targeting of HIV prevention interventions such as pre-exposure prophylaxis for MSM.

Abstract

Life chaos, the perceived inability to plan for and anticipate the future, may be a barrier to the HIV care continuum for people living with HIV who experience incarceration. Between December 2012 and June 2015, we interviewed 356 adult cisgender men and transgender women living with HIV in Los Angeles County Jail. We assessed life chaos using the Confusion, Hubbub, and Order Scale (CHAOS) and conducted regression analyses to estimate the association between life chaos and care continuum. Forty-eight percent were diagnosed with HIV while incarcerated, 14% were engaged in care 12 months prior to incarceration, mean antiretroviral adherence was 65%, and 68% were virologically suppressed. Adjusting for sociodemographics, HIV-related stigma, and social support, higher life chaos was associated with greater likelihood of diagnosis while incarcerated, lower likelihood of engagement in care, and lower adherence. There was no statistically significant association between life chaos and virologic suppression. Identifying life chaos in criminal-justice involved populations and intervening on it may improve continuum outcomes.

Passaro, R. C., Segura, E. R., Lama, J. R., Sanchez, J., Lake, J. E., Shoptaw, S., & Clark, J. L. (2020). High-Risk, but Hidden: Binge Drinking among Men Who Have Sex with Men and Transgender Women in Lima, Peru, 2012-2014. Substance use & misuse55(3), 399–404.

Abstract

Background: Binge drinking (BD) is common in Peru, but may not be routinely detected by standard assessments of hazardous drinking. Objectives: We describe prevalence and risk behaviors of men who have sex with men (MSM) and transgender women (TW) in Peru who met criteria for BD as compared with those who met criteria for hazardous drinking. Methods: In a cross-sectional sample of MSM and TW from Lima (2012-2014), we calculated prevalence of BD (consuming ≥6 alcoholic drinks per occasion by AUDIT-3 criteria), conducted bivariate analyses of associations of BD with demographic and behavioral characteristics, and compared prevalence and behaviors of BD to those of hazardous drinkers (identified by AUDIT-10 criteria). Results: Of 1,520 MSM (n = 1,384) and TW (n = 137) with median age 27 years, 74.4% of MSM and 86.9% of TW met criteria for BD. Among MSM, BD was associated with a greater likelihood of using alcohol (41.6% vs. 13.8%; p < .01) or drugs (7.8% vs. 2.8%; p < .01) prior to a recent sexual contact. Among TW, BD was associated with greater frequency of alcohol use (44.9% vs. 11.1%; p < .01) or unprotected anal intercourse (58.8% vs. 33.3%; p = .04) during ≥1 of their three most recent sexual contacts. There was a higher prevalence of BD (75.5%) than hazardous drinking (53.2%) in our sample, with binge drinkers exhibiting similar sexual risk behaviors to hazardous drinkers. Conclusions: Binge drinking is common among MSM and TW in Lima, associated with risky sexual behavior, and may not be adequately captured by AUDIT-10 criteria.

Javanbakht, M., Shoptaw, S., Ragsdale, A., Brookmeyer, R., Bolan, R., & Gorbach, P. M. (2020). Depressive symptoms and substance use: Changes overtime among a cohort of HIV-positive and HIV-negative MSM. Drug and alcohol dependence207, 107770.

Abstract:

Background: The objective of this study was to examine depressive symptoms overtime and quantify the variance in symptoms attributable to substance use among a cohort of HIV-positive and HIV-negative men.

Methods: Participants were enrolled in an NIH/NIDA funded cohort, with 534 men resulting in 1,888 visits between August 2014 and June 2018. Participants were between 18 and 45 years, and half were HIV-positive. At baseline and semi-annual visits, information was collected on depressive symptoms, sexual behaviors, and substance use. Changes overtime in symptom scores were evaluated using individual growth curve modeling.

Results: The average CES-D20 score was 19.5 (SD = 12.7). Depressive symptoms were highest among daily/weekly methamphetamine users (56% vs. 39% occasional users and 27% non-users; p value<.01). Factors independently associated with depressive symptoms included methamphetamine use (adjusted OR = 1.5; 95% CI 1.1-2.3) and transactional sex (adjusted OR = 1.8; 95% CI 1.4-2.5). Based on growth curve modeling, methamphetamine was the most influential predictor of depressive symptoms, accounting for 10% of individual variance (p value<.01). Declines in depressive symptoms were noted for heavy users of a number of drugs, except for methamphetamine. For instance, those reporting daily/weekly heroin had a 3.38 point decline in CESD20 scores overtime (p value = 0.01). However, heavy methamphetamine users had much higher CESD20 scores and their scores remained high overtime (p value for change = 0.91).

Conclusions: The prevalence of depressive symptoms among this cohort of HIV-negative and HIV-positive MSM was high, especially among frequent methamphetamine users. These findings suggest that reducing methamphetamine use may have the potential to reduce depressive symptoms.

Abstract:

Limited data exists on intimate partner violence (IPV) among transgender women (TW), though global trends suggest IPV is associated with HIV risk in this population. We describe the prevalence of verbal, physical, and/or sexual violence as well as participant- and partner-level correlates of IPV among TW in Lima, Peru. Among 389 respondents, 15.2% reported IPV with one or more of their last three sexual partners: 9.2% verbal, 8.2% physical, and 2.3% sexual violence. Physical and verbal violence were more common with stable partners (aPR 3.46, 95% CI 1.17-10.25, aPR 2.46, 95% CI 1.14-5.28, respectively). Physical violence was associated with condomless receptive anal intercourse (cRAI) (aPR 2.22, 95% CI 1.19-4.13) and partner alcohol use (aPR 4.38, 95% CI 1.56-12.33) while verbal violence correlated with participant inebriation (aPR 4.86, 95% CI 1.63-14.46). Our results link IPV with stable partnerships, alcohol use, and cRAI, suggesting TW in Peru may benefit from multidimensional IPV prevention strategies to foster supportive relationships and reduce HIV transmission.

Garcia, J., Vargas, N., Clark, J. L., Magaña Álvarez, M., Nelons, D. A., & Parker, R. G. (2020). Social isolation and connectedness as determinants of well-being: Global evidence mapping focused on LGBTQ youth. Global public health15(4), 497–519.

Abstract:

Social isolation describes a lack of a sense of belonging, the inability to engage and connect with others, and the neglect or deterioration of social relationships. This conceptual review describes how social isolation and connectedness affect the well-being of LGBTQ youth. Most studies focused on the psychosocial experience of social isolation, which led to suicide attempt, self-harm, sexual risk, and substance use. Scholarly work has drawn from a variety of frameworks, ranging from minority stress theory to positive youth development, to devise interventions that target isolation and connectedness in schools, community-based organisations, and in online environments. Finally, we discuss the importance of addressing social, cultural, and structural dimensions of social isolation in order to foster enabling environments that allow LGBTQ youth to thrive. This conceptual review suggests that individual and social transformations are the result of young people’s meaningful participation in shaping their environment, which is made possible when their capabilities are fostered through social well-being. Our findings suggest the need for measures of social isolation among youth in databanks produced by global institutions, such as the World Health Organization.

Personalized Cognitive Counseling Reduces Drinking Expectancy Among Men Who Have Sex with Men and Transgender Women in Lima, Peru: A Pilot Randomized Controlled Trial. AIDS and behavior24(11), 3205–3214.

Abstract:

Personalized cognitive counseling (PCC) is an evidence-based intervention designed to modify HIV-related risk behavior. We assessed the impact of PCC on sexual behavior, drinking expectancy, and incidence of sexually transmitted infections (STIs) in a 6-month randomized controlled trial among 153 HIV-uninfected men who have sex with men (MSM) and transgender women (TW) in Peru. Study retention was ≥ 90%, with three HIV infections (3 Control) and 19 cases of GC/CT (10 Control, 9 PCC) at 6 months. There was a decline in condomless receptive anal intercourse in the Control (0.74, 95% CI 0.60-0.91; p < 0.01) and PCC arms (0.72, 0.55-0.94; p = 0.02) at 6-month follow-up. There was a decrease in drinking expectancy at 6 months among participants endorsing alcohol use in the PCC arm (0.89, 0.83-0.96; p < 0.01), versus no change in the Control arm (0.98, 0.92-1.04; p = 0.54). PCC was efficacious in reducing drinking expectancy and HIV risk among MSM and TW in Peru.

Abstract: 

Interventions are urgently needed to reduce prescription opioid misuse risk factors, including anxiety and concomitant use of sedatives. However, only a limited number of randomized controlled opioid intervention trials have been conducted. We sought to determine whether an online behavior change/support community, compared to a control Facebook group, could reduce anxiety and opioid misuse among chronic pain patients. 51 high-risk non-cancer chronic pain patients were randomly assigned to either a Harnessing Online Peer Education (HOPE) peer-led online behavior change intervention or a control group (no peer leaders) on Facebook for 12 weeks. Inclusion criteria were: 18 years or older, a UCLA Health System patient, prescribed an opioid for non-cancer chronic pain between 3 and 12 months ago, and a score of ≥9 on the Current Opioid Misuse Measure (COMM) and/or concomitant use of benzodiazepines. Participation in the online community was voluntary. Patients completed baseline and follow-up assessments on Generalized Anxiety Disorder screener (GAD-7), COMM, and frequency of social media discussions about pain and opioid use. Compared to control group participants, intervention participants showed a baseline-to-follow-up decrease in anxiety, and more frequently used social media to discuss pain, prescription opioid use, coping strategies, places to seek help, and alternative therapies for pain. Both groups showed a baseline to follow-up decrease in COMM score. Preliminary results support the use an online community interventions as a low-cost tool to decrease risk for prescription opioid misuse and its complications.

Abstract:

We conducted a rapid, mixed-methods assessment to understand how COVID-19 affected Latinx sexual minority men (LSMM) and transgender women (LTGW). Using a computer-assisted telephone interviewing software, one interviewer called 52 participants (randomly sampled from a larger HIV prevention pilot study aiming to increase HIV knowledge and testing frequency; n = 36 LSMM and n = 16 LTGW) between 04/27/20-05/18/20. We quantified core domains using the Epidemic-Pandemic Impacts Inventory scale and provided important context through open-ended qualitative questions assessing: 1) COVID-19 infection history and experiences with quarantine; 2) Health and healthcare access; 3) Employment and economic impact of COVID-19. Participants reported increases in physical conflict or verbal arguments with a partner (13.5%) or other adult(s) (19.2%) due to stressors associated with the safer-at-home order. Participants also reported increased alcohol consumption (23.1%), problems with sleep (67.3%) and mental health (78.4%). Further, disruptions in access to Pre-Exposure Prophylaxis or PrEP-a daily pill to prevent HIV-occurred (33.3% of 18 participants who reported being on PrEP). Many said they received less medical attention than usual (34.6%), and LTGW reported delays in critical gender-affirming hormones/procedures. Half of the participants lost their jobs (50.0%); many undocumented participants relayed additional financial concerns because they did not qualify for financial assistance. Though no COVID-19 infections were noted, COVID-19 dramatically impacted other aspects of health and overall wellbeing of LSMM and LTGW. Public health responses should address the stressors faced by LSMM and LTGW during the COVID-19 pandemic and the impact on wellbeing.

H., Northrup, A., Nieto, O., Brooks, R. A., & Special Projects Of National Significance Social Media Initiative Study Group (2020). Predictors of Internet Health Information-Seeking Behaviors Among Young Adults Living With HIV Across the United States: Longitudinal Observational Study. Journal of medical Internet research22(11), e18309.

Abstract: 

Background: Consistent with young adults’ penchant for digital communication, young adults living with HIV use digital communication media to seek out health information. Understanding the types of health information sought online and the characteristics of these information-seeking young adults is vital when designing digital health interventions for them.

Objective: This study aims to describe characteristics of young adults living with HIV who seek health information through the internet. Results will be relevant to digital health interventions and patient education.

Methods: Young adults with HIV (aged 18-34 years) self-reported internet use during an evaluation of digital HIV care interventions across 10 demonstration projects in the United States (N=716). Lasso (least absolute shrinkage and selection operator) models were used to select characteristics that predicted whether participants reported seeking general health and sexual and reproductive health (SRH) information on the internet during the past 6 months.

Results: Almost a third (211/716, 29.5%) and a fifth (155/716, 21.6%) of participants reported searching for general health and SRH information, respectively; 26.7% (36/135) of transgender young adults with HIV searched for gender-affirming care topics. Areas under the curve (>0.70) indicated success in building models to predict internet health information seeking. Consistent with prior studies, higher education and income predicted health information seeking. Higher self-reported antiretroviral therapy adherence, substance use, and not reporting transgender gender identity also predicted health information seeking. Reporting a sexual orientation other than gay, lesbian, bisexual, or straight predicted SRH information seeking.

Conclusions: Young adults living with HIV commonly seek both general health and SRH information online, particularly those exploring their sexual identity. Providers should discuss the most commonly sought SRH topics and the use of digital technology and be open to discussing information found online to better assist young adults with HIV in finding accurate information. Characteristics associated with health information-seeking behavior may also be used to develop and tailor digital health interventions for these young adults.

Qualitative Evaluation of Social Media and Mobile Technology Interventions Designed to Improve HIV Health Outcomes for Youth and Young Adults Living With HIV: A HRSA SPNS Initiative. Health promotion practice21(5), 693–704.

Abstract: 

Youth and young adults living with HIV (YYALH) are less likely to be engaged in HIV care, adhere to their medications, and achieve viral suppression compared to older adult populations. In the United States, the majority of YYALH belong to racial/ethnic, sexual, and gender minority groups. HIV care interventions are needed that specifically target YYALH and that exploit the use of social media and mobile technology (SMMT) platforms, where youth and young adults have a ubiquitous presence. We conducted a qualitative evaluation of SMMT interventions included in a Health Resources and Services Administration Special Projects of National Significance initiative designed to improve medical care engagement, retention, and medication adherence to achieve viral suppression among YYALH. However, in this study, only young adults living with HIV (YALH) ages 18 to 34 years participated. A total of 48 YALH were interviewed. The data were analyzed using thematic analysis and revealed three main themes supporting the usefulness of the SMMT interventions, which included (1) acceptability of SMMT interventions in managing HIV care with subthemes of medical information accessibility, reminders, and self-efficacy; (2) feelings of support and personal connection afforded by SMMT interventions; and (3) SMMT interventions help to alleviate negative feelings about status and mitigate HIV-related stigma. A few participants identified problems with using their respective intervention, primarily related to the functionality of the technologies. Overall, findings from our qualitative evaluation suggest that SMMT-based interventions have the potential to increase engagement and retention in care, support YALH in adhering to medication, and help them adjust to their diagnosis.

Abstract:

Social media platforms offer the opportunity to develop online social networks. Use of these platforms has been particularly attractive to younger sexual and gender minority individuals as well as those living with HIV. This cross-sectional study examined the perceived level of social support and associations with social media use among youth and young adult cisgender men who have sex with men (MSM) and transgender (trans) women living with HIV and examined these associations by gender identity. The study drew from baseline data collected from 612 cisgender MSM and 162 trans women enrolling in one of 10 demonstration sites that were part of a Health Resources and Services Administration Special Projects of National Significance initiative. The individual projects were designed to evaluate the potential for social media/mobile technology-based interventions to improve retention in care and HIV health outcomes. The data used in this study came from baseline surveys completed when participants enrolled in a site between October 2016 and May 2018. Results demonstrated that a significantly greater proportion of MSM than trans women participants reported the use of social media platforms (e.g., Facebook: MSM = 86%, trans women = 62%; Instagram: MSM = 65%, trans women = 35%). Furthermore, increased social media use improved perceptions of social support only among MSM participants (direct adjusted OR = 1.49) and not trans women participants (gender identity interaction term adjusted OR = 0.64). These results revealed that MSM participants perceived greater social benefit from the use of social media platforms than trans women, which could be a result of generalized online transphobia experienced by trans women. More nuanced data on various social media platforms, that is, anonymous versus profile-based, and group differences, are needed to better understand how social media platforms can be best utilized to optimize health care outcomes among sexual and gender minority youth and young adults living with HIV.

Nieto, O., Brooks, R. A., Landrian, A., Cabral, A., & Fehrenbacher, A. E. (2020). PrEP discontinuation among Latino/a and Black MSM and transgender women: A need for PrEP support services. PloS one15(11), e0241340.

Abstract:

Purpose: Disparities persist in HIV infection among Black and Latino men who have sex with men (BLMSM) and Black and Latina transgender women (BLTW). Increasing uptake and subsequent consistent use of pre-exposure prophylaxis (PrEP), an effective biomedical strategy for preventing HIV acquisition, can dramatically reduce HIV incidence in these populations. The purpose of this study was to explore reasons for PrEP discontinuation among BLMSM and BLTW living in Los Angeles County to inform the development of support services for these populations to remain persistent with their PrEP regimen.

Methods: In-depth, semi-structured interviews were conducted with 15 BLMSM and 7 BLTW who reported either temporary or indefinite PrEP discontinuation. A thematic analysis approach was used to analyze qualitative data.

Results: Four themes emerged related to reasons for PrEP discontinuation, including: (1) lower perceived HIV risk related to changes in sexual behavior; (2) structural or logistical barriers (e.g., lapse or loss of health insurance, cost, difficulty navigating complex medical systems); (3) anticipated and experienced medication side effects, with a sub-theme of interactions between PrEP and feminizing hormone medications; and (4) challenges with medication adherence.

Conclusions: PrEP is an important prevention tool for BLMSM and BLTW, particularly during periods of heightened HIV risk. However, both individual (e.g., inability to adhere to medication, changes in HIV sexual risk behaviors) and structural/logistical (e.g., loss of insurance, navigating complex medical systems) factors can cause temporary or indefinite PrEP discontinuation. Additional support services, beyond those offered by medical providers, are needed to help BLMSM and BLTW PrEP users overcome barriers to discontinuation and assist them to remain persistent with their PrEP regimen.

Abstract: 

The purpose of this qualitative study was to identify barriers and motivators to PrEP uptake from the perspective of Black and Latina transgender women (TW) who are currently using PrEP to suggest intervention and outreach activities to increase PrEP uptake in this population. The Information-Motivation-Behavioral Skills Model guided the development of the semi-structured interview guide. A thematic analysis approach was used to analyze the data. Perceived barriers to PrEP uptake included structural and logistic barriers, language and cultural barriers to medical engagement, lack of transgender competent or gender-affirming care, and prioritizing hormone therapy over the use of PrEP. To increase PrEP uptake among BLTW, participants recommended disseminating PrEP information through a variety of methods, highlighting relationship and sexual health benefits of using PrEP, and developing effective patient-provider communication. Our findings highlight several ways to promote PrEP among BLTW. PrEP promotion should be integrated into gender-affirming care and supported by peer education and navigation services that reach BLTW in both clinic and community settings.

Responding to global stimulant use: challenges and opportunities. The Lancet. Vol 394, Iss 10209. 2019 November 2. p1652-1667.

Summary
We did a global review to synthesise data on the prevalence, harms, and interventions for stimulant use, focusing specifically on the use of cocaine and amphetamines. Modelling estimated the effect of cocaine and amphetamine use on mortality, suicidality, and blood borne virus incidence. The estimated global prevalence of cocaine use was 0·4% and amphetamine use was 0·7%, with dependence affecting 16% of people who used cocaine and 11% of those who used amphetamine. Stimulant use was associated with elevated mortality, increased incidence of HIV and hepatitis C infection, poor mental health (suicidality, psychosis, depression, and violence), and increased risk of cardiovascular events. No effective pharmacotherapies are available that reduce stimulant use, and the available psychosocial interventions (except for contingency management) had a weak overall effect. Generic approaches can address mental health and blood borne virus infection risk if better tailored to mitigate the harms associated with stimulant use. Substantial and sustained investment is needed to develop more effective interventions to reduce stimulant use.

Mind the gaps: prescription coverage and HIV incidence among patients receiving pre-exposure prophylaxis from a large federally qualified health center in Los Angeles, California.AIDS & Behavior. 2019 Apr 5.

Abstract
We conducted a records-based cohort study of patients who initiated pre-exposure prophylaxis (PrEP) at a large federally qualified health center in Los Angeles, CA to characterize patterns of PrEP use, identify correlates of PrEP discontinuation, and calculate HIV incidence. Of 3121 individuals initiating PrEP between 2014 and 2017, 42% (n = 1314) were active (i.e., had a current PrEP prescription) in April 2018. HIV incidence was 0.1/100 person-years among active PrEP patients, compared to 2.1/100 person-years among patients who discontinued. Compared to patients accessing PrEP through government programs with no prescription copay, risk of discontinuation was higher among those with private insurance (ARR = 1.4, 95% CI 1.2, 1.7), or no insurance (ARR = 4.5, 95% CI 3.2, 6.4). Sixty-three percent of active PrEP patients had gaps between PrEP prescriptions, averaging one gap per year (median length = 65 days). Increasing access to free or low-cost PrEP can improve PrEP continuity.

Abstract
Purpose: The purpose of this study was to explore risk factors for HIV and sexually transmitted infections (STIs) among transgender women (TW) in Lima, Peru. Methods: HIV-negative or serostatus unknown TW reporting recent condomless receptive anal intercourse underwent testing for STIs and HIV and completed a sociobehavioral survey. Results: Among 120 TW, 29.6% had rectal Neisseria gonorrhoeae (GC) or Chlamydia trachomatis (CT) and 12.6% had HIV. Age and migrant status were associated with rectal GC/CT, and rectal GC/CT predicted HIV infection. Conclusions: Further study is needed to understand individual and social factors that contribute to HIV/STI vulnerability among TW.

Multifactorial discrimination, discrimination salience, and prevalent experiences of internalized homophobia in middle-aged and older MSM. Aging and Mental Health. 2019 Apr 2:1-8. doi: 10.1080/13607863.2019.1594161. [Epub ahead of print]

Abstract
Objectives
We sought to test whether discrimination salience and multifactorial discrimination were associated with prevalent experiences of internalized homophobia among middle-aged and older men who have sex with men (MSM).

Methods
We analyzed data from 498 middle-aged and older MSM from the Multicenter AIDS Cohort Study (MACS) who reported any lifetime discrimination experience. We estimated the prevalence ratio of current internalized homophobia using multivariable Poisson regressions, accounting for discrimination salience, multifactorial discrimination, and covariates. We then assessed whether multifactorial discrimination moderated the association between discrimination salience and internalized homophobia.

Results
Over half (56.4%) of our sample reported any current experience of internalized homophobia. More than two-thirds reported multifactorial discrimination (68.2%) and more than one-third (36.7%) reported moderate-to-high discrimination salience. Increases in discrimination salience (PR = 1.11; 95% CI: 1.03-1.20) were associated with any current internalized homophobia among middle-aged and older MSM. Multifactorial discrimination was not statistically associated with internalized homophobia and did not moderate the association between discrimination salience and internalized homophobia.

Conclusions
Our study underscores internalized homophobia as a persisting concern among MSM in midlife and older adulthood. Our findings suggest that salience, as a characteristic of discrimination experiences, may have a greater impact on internalized homophobia compared with exposure. Future research efforts should assess facets of discrimination salience, such as severity, frequency, and chronicity, to better understand how discrimination shapes psychosocial well-being across the life course. Mental health advocates at policy, organizational, and community levels should aim to reduce intersectional stigma and address individual experiences of internalized homophobia.

Introduction and Aims
As South Africa, especially the Western Cape Province, faces an epidemic of methamphetamine use disorder, therapeutic approaches suited to the South African context are needed. This secondary analysis assessed retention and methamphetamine abstinence outcomes in response to an 8‐week pilot contingency management (CM) intervention trial of neural correlates of methamphetamine abstinence, exploring sociodemographic and clinical differences between responders and non‐responders.Design and Methods
Research participants provided thrice‐weekly monitored urine samples, which were analysed by qualitative radioimmunoassay. The primary outcome for this analysis was therapeutic response, defined as abstinence from methamphetamine (≥23 of 24 possible methamphetamine‐negative urine samples).Results
Data from 30 adults living in Cape Town, South Africa (34 ± 6.1 years of age, mean age ± SD, 21 men) were included. Sixty‐three percent (12 men) were responders. In bivariate comparisons, baseline measurements showed fewer responders reported monthly household income ≥25 000+ South African Rand (ZAR; ~USD $1880; vs. ZAR < 25 000) than non‐responders (15.8% vs. 63.6%; P = 0.007). Furthermore, responders had higher median years of education (12 vs. 10; Kruskal–Wallis χ2 = 4.25, DF = 1, P = 0.039) and lower median body mass index than non‐responders (19 vs. 24; Kruskal–Wallis χ2 = 6.84, P = 0.008).Discussion and Conclusions
Therapeutic response in this study were comparable to those obtained with CM for methamphetamine use disorder in North America and Europe. Our findings suggest that CM may be a useful component of treatment strategies to boost retention and continuous abstinence from methamphetamine in Cape Town, South Africa. Larger efficacy studies are needed in this setting.To read more, click here.

Methamphetamine use drives decreases in viral suppression for people living with HIV released from a large municipal jail: Results of the LINK LA clinical trial. Drug and alcohol dependence. 2019 Sep 1;202:178-84.

Abstract
BACKGROUND:
People living with HIV (PLWH) often experience decreases in HIV viral suppression (VS) after release from jail. The Linking Inmates to Care in LA (LINK LA) peer navigation intervention helped maintain VS 12 months after release from jail compared to standard of care. In this study, we analyzed correlates of substance use and tested whether substance use was an independent correlate of decreased VS in LINK LA participants.

METHODS:
We analyzed LINK LA data collected at baseline, 3, and 12 months. We defined high-risk drug use as any reported methamphetamine, cocaine, or opioid use in the 30 days prior to a study visit (or jail entry at baseline). We used generalized linear mixed models to test associations of sociodemographic variables with type of substance used, and we tested correlates of VS while controlling for time, the intervention, and their interaction.

RESULTS:
At baseline (n = 356), 71% of participants reported high-risk drug use: 58%, methamphetamine; 17%, cocaine; 7%, heroin; and 4%, prescription opioids. Non-Hispanic Whites and those younger than 35 were most likely to use methamphetamine; Blacks were most likely to use cocaine; people who inject drugs were most likely to use opioids. Participants who used high-risk drugs had 53% lower adjusted odds than non-users of maintaining VS (AOR 0.47, 95% CI 0.31-0.70, p < 0.001).

CONCLUSION:
High-risk drug use, dominated by methamphetamine use, independently correlated with decreased VS among recently incarcerated PLWH. Improving HIV care continuum outcomes among populations leaving jail requires attention to efforts to address high-risk drug use.

Abstract
PURPOSE OF REVIEW:
This paper reports on the results of a study comparing two behavioral treatments for methamphetamine users. The outcome was the effectiveness of the interventions in reducing meth use. The interventions were contingency management (CM) and contingency management plus strengths-based case management (CM/SBCM).

RECENT FINDINGS:
CM/SBCM was found to be associated with attending more sessions for people who reported being in a couple. Also, participants who earned more money in the first part of the study were more likely to have more clean urinalysis in the second part of the study. Latent class analysis identified a class of participants who were in a couple, without sexual abuse history, and less meth use at baseline. This class tended to have more clean urinalysis in the CM/SBCM intervention. These results indicate that incentive-based interventions with case management may be useful for helping meth users reduce their drug use.

Abstract
Life chaos, the perceived inability to plan for and anticipate the future, may be a barrier to the HIV care continuum for people living with HIV who experience incarceration. Between December 2012 and June 2015, we interviewed 356 adult cisgender men and transgender women living with HIV in Los Angeles County Jail. We assessed life chaos using the Confusion, Hubbub, and Order Scale (CHAOS) and conducted regression analyses to estimate the association between life chaos and care continuum. Forty-eight percent were diagnosed with HIV while incarcerated, 14% were engaged in care 12 months prior to incarceration, mean antiretroviral adherence was 65%, and 68% were virologically suppressed. Adjusting for sociodemographics, HIV-related stigma, and social support, higher life chaos was associated with greater likelihood of diagnosis while incarcerated, lower likelihood of engagement in care, and lower adherence. There was no statistically significant association between life chaos and virologic suppression. Identifying life chaos in criminal-justice involved populations and intervening on it may improve continuum outcomes.

The Impact of Past and Current Alcohol Consumption Patterns on Progression of Carotid Intima‐Media Thickness Among Women and Men Living with HIV Infection. Alcoholism: Clinical and Experimental Research. 2019 Jan 1.

Abstract
BACKGROUND:
The relationship between alcohol consumption and atherosclerosis has not been sufficiently examined among people living with HIV (PLWH).

METHODS:
We analyzed data from PLWH in the Women’s Interagency HIV Study (WIHS; n = 1,164) and the Multicenter AIDS Cohort Study (MACS; n = 387) with no history of cardiovascular disease (CVD). Repeated measures of intima-media thickness of the right common carotid artery (CCA-IMT) were assessed using B-mode ultrasound from 2004 to 2013. Current alcohol consumption was collected at time of CCA-IMT measurement and was categorized according to gender-specific weekly limits. Group-based trajectory models categorized participants into past 10-year consumption patterns (1994 to 2004). Multivariate generalized estimating equations were conducted to assess the association of past and current alcohol use patterns on change in CCA-IMT by cohort, controlling for age, race, cigarette and illicit drug use, probable depression, HIV RNA viral load, antiretroviral therapy exposure, and hepatitis C coinfection.

RESULTS:
Among the WIHS, past heavy alcohol consumption was associated with increased CCA-IMT level over time (β = 8.08, CI 0.35, 15.8, p = 0.04), compared to abstinence. Among the MACS, compared to abstinence, all past consumption patterns were associated with increased CCA-IMT over time (past low: β = 15.3, 95% CI 6.46, 24.2, p < 0.001; past moderate: β = 14.3, CI 1.36, 27.2, p = 0.03; past heavy: β = 21.8, CI 4.63, 38.9, p = 0.01). Current heavy consumption was associated with decreased CCA-IMT among the WIHS (β = -11.4, 95% CI -20.2, -2.63, p = 0.01) and MACS (β = -15.4, 95% CI -30.7, -0.13, p = 0.04). No statistically significant time by consumption pattern effects were found.

CONCLUSIONS:
In both cohorts, 10-year heavy consumption was associated with statistically significant increases in carotid artery thickness, compared to abstinence. Long-term patterns of drinking at any level above abstinence were particularly significant for increases in IMT among men, with heavy consumption presenting with the greatest increase. Our results suggest a potentially different window of risk among past and current heavy drinkers. Further studies are needed to determine whether alcohol consumption level is associated with intermediate measures of atherosclerosis. Alcohol screening and interventions to reduce heavy consumption may benefit PLWH who are at risk of CVD.

The Longitudinal Effects of Non-injection Substance Use on Sustained HIV Viral Load Undetectability Among MSM and Heterosexual Men in Brazil and Thailand: The Role of ART Adherence and Depressive Symptoms (HPTN 063). AIDS and Behavior. 2019 Mar 15;23(3):649-60.

Abstract
The effect of non-injection substance use on HIV viral load (VL) is understudied in international settings. Data are from HPTN063, a longitudinal observational study of HIV-infected individuals in Brazil, Thailand, and Zambia, with focus on men with VL data (Brazil = 146; Thailand = 159). Generalized linear mixed models (GLMM) assessed whether non-injection substance use (stimulants, cannabis, alcohol, polysubstance) was associated with VL undetectability. ART adherence and depressive symptoms were examined as mediators of the association. In Thailand, substance use was not significantly associated with VL undetectability or ART adherence, but alcohol misuse among MSM was associated with increased odds of depression (AOR = 2.75; 95% CI 1.20, 6.32, p = 0.02). In Brazil, alcohol misuse by MSM was associated with decreased odds of undetectable VL (AOR = 0.34; 95% CI 0.13, 0.92, p = 0.03). Polysubstance use by heterosexual men in Brazil was associated with decreased odds of ART adherence (AOR = 0.25; 95% CI 0.08, 0.78, p = 0.02). VL suppression appears attainable among non-injection substance users. Substance use interventions among HIV-positive men should address depression, adherence, and VL undetectability.

Okafor CN, Plankey MW, Li M, Chen X, Surkan PJ, Shoptaw S, Martin E, Cohen R, Sacktor N, Cook RL. Association of marijuana use with changes in cognitive processing speed and flexibility for 17 Years in HIV-seropositive and HIV-seronegative men. Substance use & misuse. 2019 Jan 30:1-3.

Abstract
BACKGROUND:
The long-term effects of marijuana on cognition, particularly in the context of HIV is not clear, as extant research shows mixed findings.

OBJECTIVE:
To determine associations between current and cumulative exposure to marijuana and changes in cognitive processing speed and flexibility in 788 HIV-seropositive (HIV+) and 1,132 HIV-seronegative (HIV-) men followed for up to 17 years in the Multicenter AIDS Cohort Study.

RESULTS:
Among HIV+ men only, current daily marijuana use compared to none-use, was significantly associated with a greater annual percentage decline in cognitive processing speed assessed with the Trail Making Test A (TMTA) (β=-0.41, 95% confidence interval (CI): -0.88, -0.03, p=0.03)] and Symbol Digit Modalities Test (SDMT) (β= -0.14, 95% CI: -0.28, -0.01, p=0.04). Further, monthly marijuana use was associated with greater annual percentage decline in cognitive flexibility assessed with the Trail Making Test B (TMTB) (β= -0.70, 95% CI: -1.34, -0.05; p=0.03] and cognitive processing speed (SDMT) (β= -0.21, 95% CI: -0.40, -0.01, p=0.03). Among the HIV- men only, each 5-marijuana use-years (equivalent to 5-years of daily marijuana use) was significantly associated with a 0.17 annual percentage decline in cognitive processing speed only (TMTA) (β= -0.18, 95% CI: -0.36, -0.01; p=0.04).

CONCLUSIONS:
Our findings suggest that marijuana use, particularly current use, may be associated with worse cognitive processing speed, but the magnitude of the estimates was not clinically meaningful.

Cook RR, Fulcher JA, Tobin NH, Li F, Lee D, Javanbakht M, Brookmeyer R, Shoptaw S, Bolan R, Aldrovandi GM, Gorbach PM. Effects of HIV viremia on the gastrointestinal microbiome of young MSM. AIDS. 2019 Apr 1;33(5):793-804.

Abstract
OBJECTIVE:
We employed a high-dimensional covariate adjustment method in microbiome analysis to better control for behavioural and clinical confounders, and in doing so examine the effects of HIV on the rectal microbiome.

DESIGN:
Three hundred and eighty-three MSM were grouped into four HIV viremia categories: HIV negative (n = 200), HIV-positive undetectable (HIV RNA < 20 copies/ml; n = 66), HIV-positive suppressed (RNA 20-200 copies/ml; n = 72) and HIV-positive viremic (RNA > 200 copies/ml; n = 45).

METHODS:
We performed 16S rRNA gene sequencing on rectal swab samples and used inverse probability of treatment-weighted marginal structural models to examine differences in microbial composition by HIV viremia category.

RESULTS:
HIV viremia explained a significant amount of variability in microbial composition in both unadjusted and covariate-adjusted analyses (R = 0.011, P = 0.02). Alterations in bacterial taxa were more apparent with increasing viremia. Relative to the HIV-negative group, HIV-positive undetectable participants showed depletions in Brachyspira, Campylobacter and Parasutterella, while suppressed participants demonstrated depletions in Barnesiella, Brachyspira and Helicobacter. The microbial signature of viremic men was most distinct, showing enrichment in inflammatory genera Peptoniphilus, Porphyromonas and Prevotella and depletion of Bacteroides, Brachyspira and Faecalibacterium, among others.

CONCLUSION:
Our study shows that, after accounting for the influence of multiple confounding factors, HIV is associated with dysbiosis in the gastrointestinal microbiome in a dose-dependent manner. This analytic approach may allow for better identification of true microbial associations by limiting the effects of confounding, and thus improve comparability across future studies.

Abstract
BACKGROUND:
HPTN 073 assessed the feasibility, acceptability, and safety of pre-exposure prophylaxis (PrEP) for Black men who have sex with men (BMSM). The purpose of this analysis was to characterize the relationship between PrEP uptake and use, and incident STIs among participants enrolled in HPTN 073.

METHODS:
226 HIV-uninfected BMSM were enrolled in three US cities; all participants received client-centered care coordination (C4) and were offered daily oral PrEP. Participants were followed for 12 months with STI testing (rectal and urine NAAT for gonorrhea and chlamydia, RPR for syphilis) conducted at baseline, week 26 and week 52. Logistic regression was used to examine associations between STI incidence and PrEP uptake. Generalized estimating equations (GEE) evaluated associations between age, PrEP acceptance, sexual behaviors, and incident STI cases.

RESULTS:
Baseline STI prevalence was 14.2%. Men <25 were more likely to have a baseline STI (25.3% vs. 6.7%; OR 4.39; 95% CI: 1.91, 10.11). Sixty participants (26.5%) acquired ≥1 STI during follow-up; the incidence rate was 34.2 cases per 100 person-years (95% CI: 27.4, 42.9). In adjusted analyses, baseline STI diagnosis (OR 4.23, 95% CI: 1.82, 9.87; p<0.001) and additional C4 time (OR 1.03, 95% CI: 1.00, 1.06; p=0.027) were associated with having an incident STI. STI incidence was not associated with PrEP acceptance or adherence.

DISCUSSION:
While we found higher rates of STIs in younger BMSM, the overall rates of STI in this trial were lower than in prior PrEP trials with no increase over time. BMSM with STIs at PrEP initiation may require additional interventions targeting STI acquisition risk.

Promising Approaches for Engaging Youth and Young Adults Living with HIV in HIV Primary Care Using Social Media and Mobile Technology Interventions: Protocol for the SPNS Social Media Initiative. JMIR Research Protocols. 2019;8(1):e10681.

Abstract
BACKGROUND:
In the United States, disparities in the rates of HIV care among youth and young adults result from the intersections of factors that include stigma, substance use, homelessness or marginal housing, institutional neglect, and mental health issues. Novel interventions are needed that are geared to youth and young adults.

OBJECTIVE:
In this paper, we aim to describe the interventions used by participating sites for Using Social Media initiative, the process for classifying the intervention components, and the methods for conducting a comprehensive evaluation of the interventions.

METHODS:
In 2015, the Health Resources and Services Administration (HRSA) HIV/AIDS Bureau, Special Projects of National Significance (SPNS) funded the Evaluation and Technical Assistance Center (ETAC) at the University of California, Los Angeles and 10 demonstration projects at sites across the United States that incorporated innovative approaches using a variety of social media and mobile technology strategies designed specifically for youth and young adults living with HIV. The ETAC developed a typology, or a classification system, that systematically summarizes the principal components of the interventions into broader groups and developed a multisite, mixed-methods approach to evaluate them based on the Department of Health and Human Services HIV health outcomes along the HIV care continuum. The mixed-methods approach is key to remove potential biases in assessing the effectiveness of demonstration projects.

RESULTS:
This SPNS project was funded in September 2015, and enrollment was completed on May 31, 2018. A total of 984 participants have been enrolled in the multisite evaluation. Data collection will continue until August 2019. However, data analysis is currently underway, and the first results are expected to be submitted for publication in 2019.

CONCLUSIONS:
This HRSA-funded initiative seeks to increase engagement in HIV medical care, improve health outcomes for people living with HIV, and reduce HIV-related health disparities and health inequities that affect HIV-positive youth and young adults.

Abstract
BACKGROUND:
Among men who have sex with men (MSM) the relationship between sexually transmitted infections (STIs) and cannabis use is not well established. We assessed cannabis use, sexual behavior, and STIs including human immunodeficiency virus (HIV) in a diverse cohort of young MSM.

METHODS:
In Los Angeles, the mSTUDY cohort conducted visits every 6 months with 512 MSM between 2014 and 2017 collecting demographics, sexual behaviors, and reports of frequency of substance use. Each visit conducted testing for gonorrhea, chlamydia, and syphilis via blood, urine, and pharyngeal and rectal swabs by PCR, Human immunodeficiency virus was assessed using rapid tests for HIV-negatives and viral load for HIV-positives. We analyzed the relationship between cannabis use, sexual behaviors and STIs/HIV across 1535 visits.

RESULTS:
Significantly fewer participants tested positive for STIs at visits when reporting the previous 6 months use of only cannabis (11.7%) compared with no drugs (16.3%) or other drugs (20.0%, P = 0.01). Fewer MSM reporting only cannabis use than no or other drug use had been incarcerated, had incarcerated partners, experienced interpersonal violence, and were HIV-positive. In multivariable analyses visits with positive STIs were associated with other drug use (adjusted odds ratio, 1.69; 95% confidence interval, 1.03-2.78) but not use of cannabis only or no drug use after controlling for age, HIV status, new sex partners, and number of sex partners.

CONCLUSIONS:
When MSM reported using cannabis exclusively fewer STIs were detected and lower risk sexual engagements reported than when MSM reported no drug or other drug use.

Pre‐exposure prophylaxis initiation and adherence among Black men who have sex with men (MSM) in three US cities: results from the HPTN 073 study. Journal of the International AIDS Society. 2019 Feb;22(2):e25223.

Abstract
INTRODUCTION:
Randomized clinical trials have demonstrated the efficacy of antiretroviral pre-exposure prophylaxis (PrEP) in preventing HIV acquisition among men who have sex with men (MSM). However, limited research has examined initiation and adherence to PrEP among Black MSM (BMSM) in the United States (US) who are disproportionately represented among newly HIV infected and late to care individuals. This research reports on the HIV Prevention Trials Network 073 (HPTN 073) study aimed to examine PrEP initiation, utilization and adherence among Black MSM utilizing the theoretically principled, culturally informed and client-centered care coordination (C4) model.

METHODS:
The HPTN 073 study enrolled and followed 226 HIV-uninfected Black MSM in three US cities (Los Angeles, CA; Washington DC; and Chapel Hill, NC) from February 2013 through September 2015. Study participants were offered once daily oral emtricitabine/tenofovir (FTC/TDF) PrEP combined with C4 and followed up for 52 weeks. Participants received HIV testing, risk reduction education and clinical monitoring.

RESULTS:
Of the 226 men enrolled, 178 participants initiated PrEP (79%), and of these 64% demonstrated PrEP utilization at week 26 (mid-point of the study) based on pharmacokinetic testing. Condomless anal sex with an HIV-infected or unknown status casual male partner was statistically significantly associated with a greater likelihood of PrEP initiation (adjusted odds ratio (OR) 4.4, 95% confidence interval (CI) 1.7, 11.7). Greater age (≥25 vs. <25, OR 2.95, 95% CI 1.37 -6.37), perception of having enough money (OR 3.6, 95% CI 1.7 to 7.7) and knowledge of male partner taking PrEP before sex (OR 2.22, 95% CI 1.03 to 4.79) were statistically significantly associated with increased likelihood of PrEP adherence at week 26. Annualized HIV incidence was 2.9 (95% CI 1.2 to 7.9) among those who initiated PrEP, compared to 7.7 (95% CI 2.5 to 24.1) among those who did not initiate PrEP (p = 0.18).

CONCLUSIONS:
Results suggest a high level of PrEP initiation among at-risk Black MSM, a group historically characterized as hard to reach. The data support the importance of addressing contextual factors that affect PrEP initiation and adherence, and of additional research on the ultimate benefit of PrEP in HIV prevention among Black MSM.

Development and Validation of the Personalized Sexual Health Promotion (SexPro) HIV Risk Prediction Model for Men Who Have Sex with Men in the United States. AIDS and behavior. 2019 Jul 27:1-0.

Abstract
Accurate HIV risk assessment among men who have sex with men (MSM) is important to help providers assess risk, and target HIV prevention interventions. We sought to develop an evidence-based HIV risk assessment tool for US MSM that is inclusive of Black MSM. Data from four large longitudinal cohorts of MSM were used to develop (EXPLORE), and validate (VAX004, HPTN061, and HVTN505). These data included visits in which participants self-reported HIV risk behavior and underwent HIV testing. We developed a pooled logistic model for incident HIV infection based on self-reported risk behaviors during the 6 months before each study visit. A total of 4069 MSM were used for the development cohort, and 8047 MSM in the three validation cohorts through 2013. The final model includes age (< 35, ≥ 35); Black race and Latino ethnicity; numbers of HIV-negative anal sex partners; number of insertive or receptive anal intercourse episodes; having 1 HIV-negative partner only; self-reported substance use; and bacterial sexually transmitted infection diagnosis. The model showed good discrimination in internal validation (C-statistic = 79.5). The external validation cohorts also showed good discrimination, with C-statistics of 73.1, 71.0, 71.9 in VAX004, HPTN061, and HVTN505 respectively, and acceptable calibration. We developed and validated an HIV risk assessment tool for MSM, which showed good predictive ability, including among the largest cohort of HIV-uninfected Black MSM in the US. This tool is available online (mysexpro.org) and can be used by providers to support targeting of HIV prevention interventions such as pre-exposure prophylaxis for MSM.

Abstract
Men who have sex with men (MSM) experience high rates of homophobic victimization, which is linked to myriad chronic physical and mental health disparities. Social adversity such as rejection, isolation, and racial discrimination can induce a conserved transcriptional response to adversity (CTRA) involving upregulation of proinflammatory genes and downregulation of type I interferon and antibody synthesis genes. This study specifically examines whether homophobic victimization is associated with expression of CTRA profiles in Black and Latino MSM living in Los Angeles. Analyses linked behavioral survey data with quantified RNA from leukocytes from blood samples of 70 participants over 12 months. CTRA gene expression was increased by 3.1-fold in MSM who experienced homophobic victimization while adjusting for major leukocyte subsets and sociodemographics. Accounting for all these factors, CTRA gene expression was significantly enhanced in MSM who identified as Black compared to Latino. Our findings identify experiences of homophobic victimization as drivers of inflammatory and type I interferon gene expression profiles, which can contribute to physical and mental health challenges in Black and Latino MSM.

Abstract

Buprenorphine has pharmacologic advantages over methadone, especially buprenorphine’s better safety profile. The true significance of buprenorphine’s introduction lies in returning the care of those suffering from opioid use disorder (OUD) to the hands of the physician. The clinical success of buprenorphine has been meager, in part because most physicians have not been exposed to treating these patients. For physicians inclined to treat OUD, the barriers to buprenorphine’s implementation have been onerous and largely counter to the norms of medical practice. Some notable concerns pertain to buprenorphine’s clinical pharmacology like street diversion, unintended use and accidental poisoning. Recently, injectable buprenorphine preparations have been introduced to mitigate these latter shortcomings. Yet, the injectable preparations’ clinical and commercial success has fallen far short of expectation. Here, we review the clinical pharmacology of these products and their expected clinical advantages for the manufacturers, clinicians, policy makers and patients, and offer our perspective, as clinicians and researchers, on how things can improve. Questions remain whether clinicians are willing to overcome barriers to treat OUD using these medications.

ABSTRACT

Background
In recent years, the number of infective endocarditis (IE) cases associated with injection drug use has increased. Clinical guidelines suggest deferring surgery for IE in people who inject drugs (PWID) due to a concern for worse outcomes in comparison to non-injectors (non-PWID). We performed a systematic review and meta-analysis of long-term outcomes in PWID who underwent cardiac surgery and compared these outcomes to non-PWID.

Methods
We systematically searched for studies reported between 1965 and 2018. We used an algorithm to estimate individual patient data (eIPD) from Kaplan-Meier (KM) curves and combined it with published individual patient data (IPD) to analyze long-term outcomes after cardiac surgery for IE in PWID. Our primary outcome was survival. Secondary outcomes were reoperation and mortality at 30-days, one-, five-, and 10-years. Random effects Cox regression was used for estimating survival.

RESULTS:
We included 27 studies in the systematic review and 19 provided data (KM or IPD) for the meta-analysis. PWID were younger and more likely to have S. aureus than non-PWID. Survival at 30-days, one-, five-, and 10-years was 94.3, 81.0, 62.1, and 56.6% in PWID, respectively; and 96.4, 85.0, 70.3, and 63.4% in non-PWID. PWID had 47% greater hazard of death (HR 1.47, 95% CI, 1.05-2.05) and more than twice the hazard of reoperation (HR 2.37, 95% CI, 1.25-4.50) than non-PWID.

Conclusion
PWID had shorter survival that non-PWID. Implementing evidence-based interventions and testing new modalities are urgently needed to improve outcomes in PWID after cardiac surgery.

Alterations to the Gastrointestinal Microbiome Associated with Methamphetamine Use among Young Men who have Sex with Men. Scientific reports9(1), 14840.

Abstract
Methamphetamine (MA) use is a major public health problem in the United States, especially among people living with HIV (PLWH). Many MA-induced neurotoxic effects are mediated by inflammation and gut microbiota may play a role in this process, yet the effects of MA on the microbiome have not been adequately explored. Therefore, we performed 16S rRNA gene sequencing on rectal swab samples from 381 men who have sex with men, 48% of whom were PLWH and 41% of whom used MA. We compared microbiome composition between MA users and non-users while testing for potential interactions with HIV and controlling for numerous confounders using inverse probability of treatment weighting. We found that MA use explained significant variation in overall composition (R2 = 0.005, p = 0.008) and was associated with elevated Finegoldia, Parvimonas, Peptoniphilus, and Porphyromonas and reduced Butyricicoccus and Faecalibacterium, among others. Genera including Actinomyces and Streptobacillus interacted with HIV status, such that they were increased in HIV+ MA users. Finegoldia and Peptoniphilus increased with increasing frequency of MA use, among others. In summary, MA use was associated with a microbial imbalance favoring pro-inflammatory bacteria, including some with neuroactive potential and others that have previously been associated with poor HIV outcomes.

ABSTRACT
Background
Although homelessness and opioid overdose are major public health issues in the U.S., evidence is limited as to whether homelessness is associated with an increased risk of opioid overdose.

Objective
To compare opioid-related outcomes between homeless versus housed individuals in low-income communities.

Design, Setting, and Participants
Cross-sectional analysis of individuals who had at least one ED visit or hospitalization in four states (Florida, Maryland, Massachusetts, and New York) in 2014.

Measurements
Risk of opioid overdose and opioid-related ED visits/hospital admissions were compared between homeless versus low-income housed individuals, adjusting for patient characteristics and hospital-specific fixed effects (effectively comparing homeless versus low-income housed individuals treated at the same hospital). We also examined whether risk of opioid-related outcomes varied by patients’ sex and race/ethnicity.

Results
A total of 96,099 homeless and 2,869,230 low-income housed individuals were analyzed. Homeless individuals had significantly higher risk of opioid overdose (adjusted risk, 1.8% for homeless vs. 0.3% for low-income housed individuals; adjusted risk difference [aRD], +1.5%; 95%CI, +1.0% to +2.0%; p < 0.001) and opioid-related ED visit/hospital admission (10.4% vs. 1.5%; aRD, +8.9%; 95%CI, +7.2% to +10.6%; p < 0.001) compared to low-income housed individuals. Non-Hispanic White females had the highest risk among the homeless population, whereas non-Hispanic White males had the highest risk among the low-income housed population.

Limitations
Individuals with no ED visit or hospitalization in 2014 were not included.

Conclusion
Homeless individuals had disproportionately higher adjusted risk of opioid-related outcomes compared to low-income housed individuals treated at the same hospital. Among homeless individuals, non-Hispanic White females incurred the highest risk. These findings highlight the importance of recognizing the homeless population-especially the non-Hispanic White female homeless population-as a high-risk population for opioid overdose.

J., & Moskowitz, J. T. (2019). Randomized controlled trial of a positive affect intervention to reduce HIV viral load among sexual minority men who use methamphetamine. Journal of the International AIDS Society22(12), e25436.

ABSTRACT
Introduction
In the era of HIV treatment as prevention (TasP), evidence-based interventions that optimize viral suppression among people who use stimulants such as methamphetamine are needed to improve health outcomes and reduce onward transmission risk. We tested the efficacy of positive affect intervention delivered during community-based contingency management (CM) for reducing viral load in sexual minority men living with HIV who use methamphetamine.

Methods
Conducted in San Francisco, this Phase II randomized controlled trial tested the efficacy of a positive affect intervention for boosting and extending the effectiveness of community-based CM for stimulant abstinence to achieve more durable reductions in HIV viral load. From 2013 to 2017, 110 sexual minority men living with HIV who had biologically confirmed, recent methamphetamine use were randomized to receive a positive affect intervention (n = 55) or attention-control condition (n = 55). All individual positive affect intervention and attention-control sessions were delivered during three months of community-based CM where participants received financial incentives for stimulant abstinence. The 5-session positive affect intervention was designed to provide skills for managing stimulant withdrawal symptoms as well as sensitize individuals to natural sources of reward. The attention-control condition consisted of neutral writing exercises and self-report measures.

Results
Men randomized to the positive affect intervention displayed significantly lower log10 HIV viral load at six, twelve and fifteen months compared to those in the attention-control condition. Men in the positive affect intervention also had significantly lower risk of at least one unsuppressed HIV RNA (≥200 copies/mL) over the 15-month follow-up. There were concurrent, statistically significant intervention-related increases in positive affect as well as decreases in the self-reported frequency of stimulant use at six and twelve months.

Conclusions
Delivering a positive affect intervention during community-based CM with sexual minority men who use methamphetamine achieved durable and clinically meaningful reductions in HIV viral load that were paralleled by increases in positive affect and decreases in stimulant use. Further clinical research is needed to determine the effectiveness of integrative, behavioural interventions for optimizing the clinical and public health benefits of TasP in sexual minority men who use stimulants such as methamphetamine.

Abstract
For individuals living with human immunodeficiency virus (HIV), viral suppression positively affects quality and length of life and reduces risks for HIV transmission. Men of color who have sex with men (MoCSM) who have been diagnosed with HIV have disproportionately low rates of viral suppression, with concomitant increases in incidence. We identified specific social, structural, and psychiatric factors associated with viral suppression among a sample of 155 HIV-positive MoCSM. Cigarette smoking and biological markers of recent drug use were significantly associated with detectable viral load. In contrast, individuals reporting a history of psychiatric illness during medical examination were more likely to be virally suppressed. Further analyses demonstrated that psychiatric illness may affect virologic outcomes through increased probability of being prescribed HIV medications. Alternatively, cigarette smoking and drug use appear to negatively affect subsequent HIV Care Continuum milestones such as medication adherence. Findings provide support for comprehensive intervention programs that emphasize prevention and treatment of cigarette, methamphetamine, and other drug use, and promote improved connection to psychiatric care. Continual achievement of this goal may be a crucial step to increase rates of viral suppression and slow HIV incidence in communities of MoCSM in Los Angeles and other urban areas.

Homophobia and heteronormativity as dimensions of stigma that influence sexual risk behaviors among men who have sex with men (MSM) and women (MSMW) in Lima, Peru: a mixed-methods analysis. BMC public health19(1), 617

ABSTRACT
Background
Stigma differentially influences HIV and STI care among MSM, especially regarding partner notification practices. Recognizing the heterogeneous behaviors/identities within the category “MSM,” we used mixed-methods to assess sexual risk behaviors among men who have sex with men only (MSMO) and behaviorally bisexual MSM (MSMW) with HIV and/or other STIs.

Methods
MSMO/MSMW recently diagnosed (< 30 days) with HIV, syphilis, urethritis, or proctitis completed a cross-sectional survey assessing sexual risk behaviors, anticipated disclosure, and sexual partnership characteristics (n = 332). Multivariable generalized estimating equation models assessed characteristics associated with female compared to male partners in the last three partnerships. Follow-up qualitative interviews (n = 30) probed partner-specific experiences (e.g., acts and disclosure).

Results
Among all participants, 13.9% (n = 46) described at least one of their last three sex partners as female (MSMW). MSMW (mean age of 31.8) reported a mean of 3.5 partners (SD = 4.5) in the past 3 months and MSMO (mean age 30.6) reported a mean of 4.6 partners (SD = 9.7) in the past 3 months. MSMW were more likely to report unprotected insertive anal sex (77.9%) than MSMO (43.1%; p < 0.01). Cisgender female partners were associated with condomless insertive sex in the last 3 months (aPR: 3.97, 95%CI: 1.98-8.00) and classification as a “primary” partnership (2.10, 1.34-3.31), and with lower prevalence of recent HIV diagnosis (0.26, 0.11-0.61). Planned notification of HIV/STI diagnoses was less common for female than for male partners (0.52, 0.31-0.85). Narratives illustrate internal (e.g., women as ‘true’ partners) and community-level processes (e.g., discrimination due to exposure of same-sex behavior) that position homosexual behavior and bisexual identity as divergent processes of deviance and generate vulnerability within sexual networks.

Conclusions
MSMW recently diagnosed with HIV/STI in Peru report varying partnership characteristics, with different partner-specific risk contexts and prevention needs. Descriptions highlight how behaviorally bisexual partnerships cut across traditional risk group boundaries and suggest that HIV/STI prevention strategies must address diverse, partnership-specific risks.

Contextualizing condoms: a cross-sectional study mapping intersections of locations of sexual contact, partner type, and substance use as contexts for sexual risk behavior among MSM in Peru. BMC infectious diseases19(1), 958.

ABSTRACT
Background
Condomless anal intercourse (CAI) appears to be increasing among men who have sex with men (MSM) globally, and is reported to be as high as 70% in recent studies in Peru. To improve understanding of the evolving context of CAI among MSM in Peru, we studied associations between partner type, substance use, and condomless anal intercourse (CAI) in locations where MSM commonly report having sexual encounters.

Methods
In a 2017 cross-sectional study of rectal STI screening and HIV prevention, a convenience sample of MSM recruited from community venues in Lima completed a survey of demographic characteristics and sexual risk behavior with their three most recent partners. Generalized estimating equations estimated correlations of CAI with location of last sexual contact, participant substance use prior to sex, and negotiation of condom use before or during sex. The network data integration application, Cytoscape, mapped intersections of partner type, sexual orientation, substance use, and CAI by four types of locations where sex occurred: 1) Home, 2) Hotel, 3) Sauna or Internet Cabin, and 4) Public Spaces.

Results
Of 447 MSM (median age 27 years), 76.9% reported CAI with ≥1 of their last three partners. Participants reported sex with casual partners most commonly in homes (64.6%) and hotels (60.4%), and with anonymous partners most often in saunas/Internet cabins (57.5%) and public spaces (52.6%). CAI was less commonly reported in hotels (aPR, 95% CI: 0.85, 0.75-0.97) compared to homes. Participants who used marijuana before sex at home were more likely to report CAI than MSM who did not use marijuana (1.36, 1.01-1.92). Partner alcohol use before sex was associated with CAI in saunas/Internet cabins (3.17, 1.45-6.91) and public spaces (2.65, 1.41-4.98). In the sexual network maps, almost all MSM who used drugs prior to their sexual encounters used drugs with more than one of their last three partners.

Conclusions
CAI was common and associated with different risk factors, like partner type and substance use, based on location where sex occurred. Novel combination HIV, STI, and substance use prevention interventions must consider how the social environments of MSM influence condom use and other sexual risk behaviors.

Integration of Gender-Affirming Primary Care and Peer Navigation With HIV Prevention and Treatment Services to Improve the Health of Transgender Women: Protocol for a Prospective Longitudinal Cohort Study. JMIR research protocols, 8(6), e14091.

ABSTRACT
Background
Public health strategies are urgently needed to improve HIV disparities among transgender women, including holistic intervention approaches that address those health needs prioritized by the community. Hormone therapy is the primary method by which many transgender women medically achieve gender affirmation. Peer navigation has been shown to be effective to engage and retain underserved populations living with HIV in stable primary medical care.

Objective
This study aims to assess the feasibility and acceptability of an integrated innovative HIV service delivery model designed to improve HIV prevention and care by combining gender-affirming primary care and peer navigation with HIV prevention and treatment services.

Methods
A 12-month, nonrandomized, single-arm cohort study was implemented in Lima, Peru, among adult individuals, assigned a male sex at birth, who identified themselves as transgender women, regardless of initiation or completion of medical gender affirmation, and who were unaware of their HIV serostatus or were living with HIV but not engaged in HIV treatment. HIV-negative participants received quarterly HIV testing and were offered to initiate pre-exposure prophylaxis. HIV-positive participants were offered to initiate antiretroviral treatment and underwent quarterly plasma HIV-1 RNA and peripheral CD4+ lymphocyte cell count monitoring. All participants received feminizing hormone therapy and adherence counseling and education on their use. Peer health navigation facilitated retention in care by visiting participants at home, work, or socialization venues, or by contacting them by social media and phone.

Results
Patient recruitment started in October 2016 and finished in March 2017. The cohort ended follow-up on March 2018. Data analysis is currently underway.

Conclusions
Innovative and culturally sensitive strategies to improve access to HIV prevention and treatment services for transgender women are vital to curb the burden of HIV epidemic for this key population. Findings of this intervention will inform future policies and research, including evaluation of its efficacy in a randomized controlled trial.

ABSTRACT

Purpose: In the United States, HIV disproportionally affects Black and Latina transgender women (BLTW). Pre-exposure prophylaxis (PrEP) is a proven biomedical method for preventing HIV acquisition. However, the social stigma attached to using PrEP may deter uptake and persistence of PrEP among BLTW, two highly vulnerable populations. The purpose of this study was to explore the experiences of PrEP stigma among BLTW who are using PrEP in Los Angeles County.

Methods: In-depth, semistructured interviews were conducted with BLTW PrEP users (N=19) to explore experiences of anticipated, enacted, and internalized PrEP stigma within the context of their unique social and contextual factors. A thematic analysis approach was used in the analysis of qualitative data.

Results: We noted an underlying theme of HIV stigma related to participants’ identification as trans women that served as the social context for other experiences. In addition, our data revealed five themes related to the experience of using PrEP. Three themes were specifically related to PrEP stigma and included: (1) Perception that BLTW PrEP users are HIV-positive; (2) perception that BLTW PrEP users engage in elevated sexual risk behaviors; and (3) negative labels ascribed to BLTW PrEP users. A fourth theme identified was the positive experiences of social support after PrEP disclosure reported by BLTW. Our fifth theme identified involved the dissemination of PrEP information by BLTW to friends/peers and sex partners.

Conclusion: BLTW experience PrEP stigma within the context of PrEP disclosure. This experience is underscored by existing experiences of HIV stigma connected to their identity as trans women. PrEP providers should prepare BLTW to use selective disclosure practices when revealing their PrEP use to help minimize experiences of PrEP stigma or potential physical harm. PrEP implementation programs should also support peer-to-peer PrEP education programs for transg

Abstract
The Centers for Disease Control and Prevention (CDC) estimates the lifetime HIV risk is one in four for Latino men who have sex with men (MSM). Pre-Exposure Prophylaxis (PrEP) is an efficacious biomedical prevention strategy to help prevent the acquisition of HIV. At present, there has been limited uptake of PrEP by Latino MSM. Unfortunately, the negative perceptions and social stigma surrounding PrEP and those who use it may deter uptake of this novel prevention strategy, particularly among high-risk Latino MSM. In this qualitative study, we explore the experiences of using PrEP among Latino MSM. Participants were recruited using gay-oriented social and sexual networking apps to complete an interviewer-administered, semi-structured qualitative interview. Thematic analysis was used to identify emerging themes relating to perceptions of PrEP users and PrEP as an HIV prevention strategy. Major themes included: feelings of protection and sexual freedom; negative and stigmatizing labels associated with PrEP use; assumptions about sexual behaviors and perceptions of sexual risk taking and irresponsibility; and attitudes related to PrEP use in relationships. A striking but not prevalent theme was the perception reported by participants that monolingual Spanish-speaking Latino MSM are skeptical about the effectiveness of PrEP. These findings suggest that efforts are needed to address the stigmatizing and negative perceptions of PrEP that persist in the gay community that may deter adoption among Latino MSM.

Speed kills: Associations between methamphetamine use, HIV infection, tobacco use, and accelerated mortality among gay and bisexual men in Los Angeles, CA 20years after methamphetamine dependence treatment. Drug and Alcohol Dependence. 2018 Nov 11.

Abstract
BACKGROUND:
To better characterize mortality among methamphetamine users, we estimated rates of all-cause mortality by HIV serostatus and smoking history in gay and bisexual men (GBM) treated for methamphetamine dependence, and explored associated clinical and socio-behavioral characteristics.

METHODS:
We searched public records to identify deaths among men screened between 1998-2000 for a trial of outpatient therapy for GBM with methamphetamine dependence. Crude mortality rates (CMRs) were calculated, and standardized mortality ratios (SMRs) estimated, comparing data with historical information from CDC WONDER. Associations of mortality with HIV infection, tobacco use, and other factors were explored using Kaplan-Meier survival analysis and Cox proportional hazards models.

RESULTS:
Of 191 methamphetamine-dependent GBM (median age 35 years; majority Caucasian), 62.8% had HIV infection, and 31.4% smoked tobacco at baseline. During the 20-year follow-up period, 12.6% died. Relative to controls, methamphetamine-dependent GBM had a three-fold higher 20-year SMR: 3.39, 95% CI: 2.69-4.09. Especially high mortality was observed among participants reporting tobacco use (adjusted HR 3.48, 95% CI: 1.54-7.89), club drug use prior to starting methamphetamine (2.63, 1.15-6.00), or other clinical diagnoses at baseline (3.89, 1.15-13.22). At 20 years, the CMR for HIV infected participants (7.7 per 1000 PY) was 1.5 times that for men without HIV (5.2 per 1000 PY; p = 0.22) and there was a 5-fold difference in CMRs for HIV infected tobacco smokers (16.9 per 1000 PY) compared to non-smokers (3.4 per 1000 PY; p < 0.01).

CONCLUSION:
In our sample of methamphetamine-dependent GBM, concomitant HIV infection and tobacco use were associated with dramatic increases in mortality.

Abstract

In North America, opioid use and its harms have increased in the United States and Canada over the past 2 decades. However, Mexico has yet to document patterns suggesting a higher level of opioid use or attendant harms. Historically, Mexico has been a country with low-level use of opioids, although heroin use has been documented. Low-level opioid use is likely attributable to structural, cultural, and individual factors. However, a range of dynamic factors may be converging to increase the use of opioids: legislative changes to opioid prescribing, national health insurance coverage of opioids, pressure from the pharmaceutical industry, changing demographics and disease burden, forced migration and its trauma, and an increase in the production and trafficking of heroin. In addition, harm-reduction services are scarce. Mexico may transition from a country of low opioid use to high opioid use but has the opportunity to respond effectively through a combination of targeted public health surveillance of high-risk groups, preparation of appropriate infrastructure to support evidence-based treatment, and interventions and policies to avoid a widespread opioid use epidemic.

Abstract
Background
Men who have sex with men with histories of homophobic victimization bear heightened risk of unstable housing and methamphetamine use. However, it is unclear whether unstable housing explains the link between homophobic victimization and methamphetamine use in this group. The present study aims to test associations between homophobic victimization, unstable housing, and recent methamphetamine use across 24 months in a cohort of men of color who have sex with men (MoCSM).

Our analysis stems from data of 1,342 person-visits from 401 MoCSM participating in an ongoing cohort study. We performed a lagged multilevel negative binominal regression to test the association between past homophobic victimization and recent unstable housing, and a lagged multilevel ordered logistic regression to test the association between past homophobic victimization recent methamphetamine use. We then performed a path analysis to test whether recent unstable housing mediates the association between past homophobic victimization and recent methamphetamine use.

Results
Findings showed homophobic victimization associated significantly with increased odds of unstable housing (IRR = 1.70, 95% CI [1.35, 2.14], p < .001) and recent methamphetamine use (OR = 1.40, 95% CI [1.15, 1.71], p = .001). Mediation analysis indicated that past homophobic victimization was indirectly associated with recent methamphetamine use via unstable housing (OR = 1.06 (95% CI [1.01, 1.11], p = .010).

Conclusion
Our findings suggest that homophobic victimization and unstable housing should be addressed alongside treatment and prevention of methamphetamine use in MoCSM.

Javanbakht M, Ragsdale A, Shoptaw S, Gorbach PM. Transactional Sex among Men Who Have Sex with Men: Differences by Substance Use and HIV Status. Journal of Urban Health. 2018 Aug:1-3. 2018 Aug 22.

Abstract: 

Exchanging money, drugs, and other goods for sex has been associated with sexual risk behaviors and increased STIs/HIV. While female sex work is well described, data on men who exchange sex for money or goods are more limited. This paper examined the prevalence and correlates of transactional sex among young men who have sex with men, especially focusing on substance use and HIV status. We conducted a cohort study of 511 participants recruited between August 2014 and December 2017 in Los Angeles, CA. Eligible participants were: (1) between 18 and 45 years of age; (2) male; and (3) if HIV-negative, reported condomless anal intercourse with a male partner in the past 6 months. By design, half were HIV-positive and half HIV-negative. At baseline and semi-annual follow-up visits, computer-assisted self-interviews were used to collect information on demographics, sexual behaviors including transactional sex which was defined as exchange of money, drugs, or a place to stay for anal intercourse. Laboratory testing was conducted for current STI/HIV status. The average age of participants was 31.4 years with 43% identifying as African American, followed by 36% as Hispanic/Latino. The prevalence of recent transactional sex across 1486 study visits was 17% (n = 255), with 74% of those reporting exchanging sex for drugs. The prevalence of transactional sex was higher among those who reported unstable housing (32 vs. 11%; p value < .01), concurrent sexual partnerships (26 vs. 9%; p value < .01), and transgender sex partners (40 vs. 15%; p value < .01). Those who reported receiving money, drugs, or shelter for sex were also more likely to report giving money, drugs, shelter for sex than men who did not report exchange sex (77 vs. 11%; p value < .01). Based on multivariable analyses after adjusting for age and race/ethnicity, HIV viral load was independently associated with transactional sex [adjusted odds ratio (AOR) = 1.4; 95% confidence interval (CI) 1.1-1.7) per log10 increase]. Additionally, those testing positive for an STI were nearly twice as likely to report transactional sex as compared to those without STIs (AOR = 1.9; 95% CI 1.2-3.5). These findings underscore the relatively high prevalence of transactional sex and its potential role in ongoing HIV transmission among this cohort of high-risk HIV-negative and HIV-positive men who have sex with men.

Abstract
The Centers for Disease Control and Prevention (CDC) estimates the lifetime HIV risk is one in four for Latino men who have sex with men (MSM). Pre-Exposure Prophylaxis (PrEP) is an efficacious biomedical prevention strategy to help prevent the acquisition of HIV. At present, there has been limited uptake of PrEP by Latino MSM. Unfortunately, the negative perceptions and social stigma surrounding PrEP and those who use it may deter uptake of this novel prevention strategy, particularly among high-risk Latino MSM. In this qualitative study, we explore the experiences of using PrEP among Latino MSM. Participants were recruited using gay-oriented social and sexual networking apps to complete an interviewer-administered, semi-structured qualitative interview. Thematic analysis was used to identify emerging themes relating to perceptions of PrEP users and PrEP as an HIV prevention strategy. Major themes included: feelings of protection and sexual freedom; negative and stigmatizing labels associated with PrEP use; assumptions about sexual behaviors and perceptions of sexual risk taking and irresponsibility; and attitudes related to PrEP use in relationships. A striking but not prevalent theme was the perception reported by participants that monolingual Spanish-speaking Latino MSM are skeptical about the effectiveness of PrEP. These findings suggest that efforts are needed to address the stigmatizing and negative perceptions of PrEP that persist in the gay community that may deter adoption among Latino MSM.

Abstract
BACKGROUND:
Previous studies have suggested that varenicline, an α4β2 nicotinic receptor partial agonist, and α7 nicotinic receptor full agonist, may be effective for the treatment of methamphetamine (MA) dependence due to dopaminergic effects, relief of glutamatergic and cognitive dysfunction, and activation of nicotinic cholinergic systems. This study aimed to determine if varenicline (1 mg BID) resulted in reduced methamphetamine use compared to placebo among treatment-seeking MA-dependent volunteers.

METHODS:
Treatment-seeking MA-dependent volunteers were randomized to varenicline 1 mg twice daily (n = 27) or placebo (n = 25) and cognitive behavioral therapy for 9 weeks. The primary outcomes were the proportion of participants achieving end-of-treatment-abstinence (EOTA, MA-negative urine specimens during weeks 8 and 9) and the treatment effectiveness score (TES, number of MA-negative urine specimens) for varenicline versus placebo.

RESULTS:
There was no significant difference in EOTA between varenicline (15%, 4/27) and placebo (20%, 5/25; p = 0.9). There was some suggestion that urinary confirmed medication compliance corresponded with EOTA in the varenicline condition, though it did not reach statistical significance, OR = 1.57 for a 100 ng/ml increase in urine varenicline, p = 0.10, 95% CI (0.99, 3.02). There was no significant difference in mean TES in the varenicline condition (8.6) compared to the placebo condition (8.1), and treatment condition was not a statistically significant predictor of TES, IRR = 1.01, p = 0.9, 95% CI (0.39, 2.70).

CONCLUSIONS:
The results of this study indicate that 1 mg varenicline BID was not an effective treatment for MA dependence among treatment-seeking MA-dependent volunteers.

Abstract

For individuals living with human immunodeficiency virus (HIV), viral suppression positively affects quality and length of life and reduces risks for HIV transmission. Men of color who have sex with men (MoCSM) who have been diagnosed with HIV have disproportionately low rates of viral suppression, with concomitant increases in incidence. We identified specific social, structural, and psychiatric factors associated with viral suppression among a sample of 155 HIV-positive MoCSM. Cigarette smoking and biological markers of recent drug use were significantly associated with detectable viral load. In contrast, individuals reporting a history of psychiatric illness during medical examination were more likely to be virally suppressed. Further analyses demonstrated that psychiatric illness may affect virologic outcomes through increased probability of being prescribed HIV medications. Alternatively, cigarette smoking and drug use appear to negatively affect subsequent HIV Care Continuum milestones such as medication adherence. Findings provide support for comprehensive intervention programs that emphasize prevention and treatment of cigarette, methamphetamine, and other drug use, and promote improved connection to psychiatric care. Continual achievement of this goal may be a crucial step to increase rates of viral suppression and slow HIV incidence in communities of MoCSM in Los Angeles and other urban areas.

Abstract/Summary:

OBJECTIVES:
A randomized controlled study was conducted with 422 homeless, stimulant-using gay/bisexual (G/B) men and 29 transgender women (n = 451) to assess two community-based interventions to reduce substance abuse and improve health: (a) a nurse case-managed program combined with contingency management (NCM + CM) versus (b) standard education plus contingency management (SE + CM).

STUDY DESIGN:
Hypotheses tested included: a) completion of hepatitis A/B vaccination series; b) reduction in stimulant use; and c) reduction in number of sexual partners.

METHODS:
A deconstructive cost analysis approach was utilized to capture direct costs associated with the delivery of both interventions. Based on an analysis of activity logs and staff interviews, specific activities and the time required to complete each were analyzed as follows: a) NCM + CM only; b) SE + CM only; c) time to administer/record vaccines; and d) time to receive and record CM visits. Cost comparison of the interventions included only staffing costs and direct cash expenditures.

RESULTS:
The study outcomes showed significant over time reductions in all measures of drug use and multiple sex partners, compared to baseline, although no significant between-group differences were detected. Cost analysis favored the simpler SE + CM intervention over the more labor-intensive NCM + CM approach. Because of the high levels of staffing required for the NCM relative to SE, costs associated with it were significantly higher.

CONCLUSIONS:
Findings suggest that while both intervention strategies were equally effective in achieving desired health outcomes, the brief SE + CM appeared less expensive to deliver.

Hermanstyne KA, Green Jr HD, Cook R, Tieu HV, Dyer TV, Hucks-Ortiz C, Wilton L, Latkin C, Shoptaw S. Social Network Support and Decreased Risk of Seroconversion in Black MSM: Results of the BROTHERS (HPTN 061) Study. Journal of Acquired Immune Deficiency Syndromes. 2018 Jun 1;78(2):163-8.

Abstract
BACKGROUND AND SETTING:
Black men who have sex with men (BMSM) in the United States have disproportionately high HIV infection rates. Social networks have been shown to influence HIV risk behavior; however, little is known about whether they affect the risk of HIV seroconversion. This study uses data from the BROTHERS (HPTN 061) study to test whether contextual factors related to social networks are associated with HIV seroconversion among BMSM.

METHODS:
We analyzed data from the BROTHERS study (2009-2011), which examined a multicomponent intervention for BMSM in 6 US cities. We ran a series of Cox regression analyses to examine associations between time-dependent measures of network support (personal/emotional, financial, medical, and social participation) and time to HIV seroconversion. We ran unadjusted models followed by models adjusted for participant age at enrollment and study location.

RESULTS:
A total of 1000 BMSM tested HIV negative at baseline and were followed at 6- and 12-month study visits. Twenty-eight men tested HIV positive. In adjusted hazard ratio models, study participants who remained HIV negative had higher proportions of social network members who provided personal/emotional {0.92 [95% confidence interval (CI): 0.85 to 0.99]}, medical [0.92 (95% CI: 0.85 to 0.99)], or social participation [0.91 (95% CI: 0.86 to 0.97)] support.

CONCLUSION:
Findings suggest that the increased presence of social network support can be protective against HIV acquisition. Future research should explore the processes that link social network support with sexual and other transmission risk behaviors as a basis to inform HIV prevention efforts.

Hermanstyne KA, Shoptaw S, Cunningham WE. Associations of types of substances with condomless sex in vulnerable people living with HIV/AIDS. Journal of HIV/AIDS & Social Services. 2018 Apr 3;17(2):118-26.

Abstract:
For people living with HIV who are not readily retained in medical care, substance use can contribute to risky sexual behavior that may lead to HIV transmission. This cross-sectional study examined the relationship between stimulants versus opioids and condomless sex in a sample of 223 vulnerable people living with HIV/AIDS. We examined the associations of stimulant and opioid use in the past 30 days with condomless sex while controlling for sample characteristics. More than two thirds (69%) reported having condomless sex in the past six months. Results showed a positive association between condomless sex and any illicit substance use (AOR: 2.82; 95% CI: 1.29–6.17; P = 0.009) or stimulant use (AOR: 2.54; 95% CI: 1.04–6.24; P = 0.041) in the past 30 days. These findings suggest the importance of promoting behavioral interventions that increase consistent condom use and reduce stimulant use among people who have difficulties with HIV care retention.

Abstract
HIV acquisition during pregnancy and breastfeeding significantly contributes toward paediatric HIV infection; however, little is known about risk behaviours in HIV-uninfected pregnant and postpartum women. We conducted twenty-six in-depth-interviews between July and December 2016 using a semi-structured interview guide among HIV-uninfected pregnant and recently postpartum women at-risk of HIV acquisition (defined as reporting ≥1 of the following: partner’s serostatus unknown or HIV-infected, recent condomless sex in pregnancy, and/or alcohol use during pregnancy) who attended primary healthcare services. Our study contextualizes factors related to risky sexual behaviours during pregnancy and postpartum periods and assesses knowledge and hypothetical acceptability of pre-exposure prophylaxis (PrEP) in pregnancy. Translated and transcribed data were coded and analysed by three researchers using a thematic analysis approach. In interviews with HIV-uninfected pregnant/postpartum women at-risk of HIV acquisition, we identified common themes associated with sexual risk behaviours during pregnancy, including: lack of control over decisions in sex and condom use in pregnancy, low perceived risk (e.g. beliefs that their partner has the same HIV-negative serostatus), and socio-cultural beliefs around condom use during pregnancy (e.g. contact with sperm is essential for baby’s development). PrEP knowledge was low among HIV-uninfected pregnant and breastfeeding women, and potential acceptability was good, though primary concerns were around the potential impact on the infant. While mothers presented a clear desire to protect themselves from HIV acquisition once pregnant, they also reported lack of control, and socio-cultural beliefs, like sex is good for the baby, that increased their risk of seroconversion. Mothers had limited PrEP awareness but reported hypothetical willingness to use PrEP because of concerns over HIV acquisition and onward mother to child transmission.

Abstract
HIV and other sexually transmitted infections (STIs) continue to affect men who have sex with men (MSM) and transgender women (TW) in Peru at disproportionately high rates. The ineffectiveness of traditional prevention strategies may be due to the disconnect between health promotion messages and community-level understandings of sexual cultures. We conducted 15 workshops with MSM and TW to develop a community-based sexual health intervention. Intervention development consisted of focus groups and scenic improvisation to identify sexual scripts for an HIV prevention telenovela, or Spanish soap opera. Workshops were stratified by self-reported socioeconomic status, sexual orientation, and gender identity: (1) low-income MSM (n = 9); (2) middle/high-income MSM (n = 6); and (3) TW (n = 8). Employing a conceptual model based on sexual scripts and critical consciousness theories, this paper reports on three themes identified during the telenovela-development process as participants sought to “rescript” social and sexual stereotypes associated with HIV-related vulnerability: (1) management of MSM and TW social identities at the intersection of socioeconomic status, sexuality, and gender performance; (2) social constructions of gender and/or sexual role and perceived and actual HIV/STI risk(s) within sexual partnership interactions; and (3) idealized and actual sexual scripts in the negotiation of safer sex practices between MSM/TW and their partners. These findings are key to reframing existing prevention strategies that fail to effectively engage poorly defined “high-risk populations.” Leveraging community-based expertise, the results provide an alternative to the static transfer of information through expert-patient interactions in didactic sessions commonly used in HIV prevention interventions among MSM and TW.

Abstract
Prescription opioid misuse is an ongoing and escalating epidemic. Although these pharmacological agents are highly effective analgesics prescribed for different types of pain, opioids also induce euphoria, leading to increasing diversion and misuse. Opioid use and related mortalities have developed in spite of initial claims that OxyContin, one of the first opioids prescribed in the USA, was not addictive in the presence of pain. These claims allayed the fears of clinicians and contributed to an increase in the number of prescriptions, quantity of drugs manufactured, and the unforeseen diversion of these drugs for non-medical uses. Understanding the history of opioid drug development, the widespread marketing campaign for opioids, the immense financial incentive behind the treatment of pain, and vulnerable socioeconomic and physical demographics for opioid misuse give perspective on the current epidemic as an American-born problem that has expanded to global significance. In light of the current worldwide opioid epidemic, it is imperative that novel opioids are developed to treat pain without inducing the euphoria that fosters physical dependence and addiction. We describe insights from preclinical findings on the properties of opioid drugs that offer insights into improving abuse-deterrent formulations. One finding is that the ability of some agonists to activate one pathway over another, or agonist bias, can predict whether several novel opioid compounds bear promise in treating pain without causing reward among other off-target effects. In addition, we outline how the pharmacokinetic profile of each opioid contributes to their potential for misuse and discuss the emergence of mixed agonists as a promising pipeline of opioid-based analgesics. These insights from preclinical findings can be used to more effectively identify opioids that treat pain without causing physical dependence and subsequent opioid abuse.

Athanasos P, Ling W, Bochner F, White JM, Somogyi AA. Buprenorphine Maintenance Subjects Are Hyperalgesic and Have No Antinociceptive Response to a Very High Morphine Dose. Pain Medicine. 2018 Mar 5.

Abstract
OBJECTIVE:
Acute pain management in opioid-dependent persons is complicated because of tolerance and opioid-induced hyperalgesia. Very high doses of morphine are ineffective in overcoming opioid-induced hyperalgesia and providing antinociception to methadone-maintained patients in an experimental setting. Whether the same occurs in buprenorphine-maintained subjects is unknown.

DESIGN:
Randomized double-blind placebo-controlled. Subjects were tested on two occasions, at least five days apart, once with intravenous morphine and once with intravenous saline. Subjects were tested at about the time of putative trough plasma buprenorphine concentrations.

SETTING:
Ambulatory.

SUBJECTS:
Twelve buprenorphine-maintained subjects: once daily sublingual dose (range = 2-22 mg); no dose change for 1.5-12 months. Ten healthy controls.

METHODS:
Intravenous morphine bolus and infusions administered over two hours to achieve two separate pseudo-steady-state plasma concentrations one hour apart. Pain tolerance was assessed by application of nociceptive stimuli (cold pressor [seconds] and electrical stimulation [volts]). Ten blood samples were collected for assay of plasma morphine, buprenorphine, and norbuprenorphine concentrations until three hours after the end of the last infusion; pain tolerance and respiration rate were measured to coincide with blood sampling times.

RESULTS:
Cold pressor responses (seconds): baseline: control 34 ± 6 vs buprenorphine 17 ± 2 (P = 0.009); morphine infusion-end: control 52 ± 11(P = 0.04), buprenorphine 17 ± 2 (P > 0.5); electrical stimulation responses (volts): baseline: control 65 ± 6 vs buprenorphine 53 ± 5 (P = 0.13); infusion-end: control 74 ± 5 (P = 0.007), buprenorphine 53 ± 5 (P > 0.98). Respiratory rate (breaths per minute): baseline: control 17 vs buprenorphine 14 (P = 0.03); infusion-end: control 15 (P = 0.09), buprenorphine 12 (P < 0.01). Infusion-end plasma morphine concentrations (ng/mL): control 23 ± 1, buprenorphine 136 ± 10.

CONCLUSIONS:
Buprenorphine subjects, compared with controls, were hyperalgesic (cold pressor test), did not experience antinociception, despite high plasma morphine concentrations, and experienced respiratory depression. Clinical implications are discussed.

Abstract
BACKGROUND:
There are sex differences in buprenorphine/naloxone clinical trials for opioid use. While women have fewer opioid-positive urine samples, relative to men, a significant decrease in opioid-positive samples was found during treatment for men, but not women. In order to inform sex-based approaches to improve treatment outcomes, research is needed to determine if opioid use, and predictors of opioid use, differs between men and women during treatment.

OBJECTIVES:
To test for sex differences in opioid use during a buprenorphine/naloxone clinical trial and determine if sex differences exist in the associations between addiction-related problem areas and opioid use over the course of the trial.

METHOD:
This secondary data analysis of the National Drug Abuse Treatment Clinical Trials Network (CTN) 0003 examined sex differences (men = 347, women = 169) in opioid-positive samples in a randomized clinical trial comparing 7-day vs. 28-day buprenorphine/naloxone tapering strategies. Addiction-related problem areas were defined by Addiction Severity-Lite (ASI-L) domain composite scores.

RESULTS:
Women were more likely than men to use opioids during the course of the buprenorphine/naloxone clinical trial (B = .33, p = .01) and medical issues were positively related to submitting an opioid-positive sample during treatment for women (B = 1.67, p = .01). No ASI-L domain composite score was associated with opioid-positive samples during treatment for men.

CONCLUSION:
Women were more likely than men to use opioids during the course of the buprenorphine/naloxone clinical trial, and medical issues predicted opioid use during treatment for women but not men. Complementary treatment for medical problems during opioid replacement therapy may benefit women.

Abstract
African-American men who have sex with men and women (MSMW) are among those most heavily impacted by HIV in the United States, and those who have histories of incarceration are at further risk of infection. The Men in Life Environments (MILE) HIV prevention intervention was developed to provide culturally appropriate skills-based education and support for African-American MSMW with recent histories of incarceration. The MILE’s conceptual framework was informed by three theories: Theory of Reasoned Action and Planned Behavior, Critical Thinking and Cultural Affirmation Model, and Empowerment Theory. The theory-based framework posits that improving racial pride is crucial in building self-efficacy and intentions that in turn promote health-protective behaviors. Therefore, our study aimed to assess whether baseline associations between racial pride and condom use self-efficacy, intentions, and behaviors among African-American MSMW with histories of incarceration align with our conceptual model. We report data on 212 participants recruited from Los Angeles County Sheriff’s Department Men’s Central Jail and the local community. Using structural equation modeling, we tested two separate models: one with female sexual partners and one with male sexual partners, while stratifying by participant’s HIV status. Only among HIV-negative participants was greater racial pride associated with less condomless intercourse with men. In this group, greater self-efficacy and intentions-but not racial pride-predicted less condomless intercourse with women. Our findings suggest that racial pride is an important factor to address in HIV prevention interventions for post-incarcerated African-American MSMW.

Adherence to self-monitoring healthy lifestyle behaviours through mobile phone-based ecological momentary assessments and photographic food records over 6 months in mostly ethnic minority mothers. Public health nutrition. 2018 Mar;21(4):679-88.

Abstract
OBJECTIVE:
Mobile phones can replace traditional self-monitoring tools through cell phone-based ecological momentary assessment (CEMA) of lifestyle behaviours and camera phone-based images of meals, i.e. photographic food records (PFR). Adherence to mobile self-monitoring needs to be evaluated in real-world treatment settings. Towards this goal, we examine CEMA and PFR adherence to the use of a mobile app designed to help mothers self-monitor lifestyle behaviours and stress. Design/Setting In 2012, forty-two mothers recorded CEMA of diet quality, exercise, sleep, stress and mood four times daily and PFR during meals over 6 months in Los Angeles, California, USA.

SUBJECTS:
A purposive sample of mothers from mixed ethnicities.

RESULTS:
Adherence to recording CEMA at least once daily was higher compared with recording PFR at least once daily over the study period (74 v. 11 %); adherence to both types of reports decreased over time. Participants who recorded PFR for more than a day (n 31) were more likely to be obese v. normal- to overweight and to have higher blood pressure, on average (all P<0·05). Based on random-effects regression, CEMA and PFR adherence was highest during weekdays (both P<0·01). Additionally, PFR adherence was associated with older age (P=0·04). CEMA adherence was highest in the morning (P<0·01). PFR recordings occurred throughout the day.

CONCLUSIONS:
Variations in population and temporal characteristics should be considered for mobile assessment schedules. Neither CEMA nor PFR alone is ideal over extended periods.

Abstract
To describe patterns of depressive symptoms across 10-years by HIV status and to determine the associations between depressive symptom patterns, HIV status, and clinical profiles of persons living with HIV from the Multicenter AIDS Cohort Study (N = 980) and Women’s Interagency HIV Study (N = 1744). Group-based trajectory models were used to identify depressive symptoms patterns between 2004 and 2013. Multinomial logistic regressions were conducted to determine associations of depression risk patterns. A 3-group model emerged among HIV-negative women (low: 58%; moderate: 31%; severe: 11%); 5-groups emerged among HIV-positive women (low: 28%; moderate: 31%; high: 25%; decreased: 7%; severe: 9%). A 4-group model emerged among HIV-negative (low: 52%; moderate: 15%; high: 23%; severe: 10%) and HIV-positive men (low: 34%; moderate: 34%; high: 22%; severe: 10%). HIV+ women had higher odds for moderate (adjusted odds ratio [AOR] 2.10, 95% CI 1.63-2.70) and severe (AOR 1.96, 95% CI 1.33-2.91) depression risk groups, compared to low depression risk. HIV+ men had higher odds for moderate depression risk (AOR 3.23, 95% CI 2.22-4.69), compared to low risk. The Framingham Risk Score, ART use, and unsuppressed viral load were associated with depressive symptom patterns. Clinicians should consider the impact that depressive symptoms may have on HIV prognosis and clinical indicators of comorbid illnesses.

Gabapentin Enacarbil Extended‐Release for Alcohol Use Disorder: A Randomized, Double‐Blind, Placebo‐Controlled, Multisite Trial assessing Efficacy and Safety. Alcoholism: Clinical and Experimental Research. 2018 Nov 7.

Abstract
BACKGROUND:
Several single-site alcohol treatment clinical trials have demonstrated efficacy for immediate-release (IR) gabapentin in reducing drinking outcomes among individuals with alcohol dependence. The purpose of this study was to conduct a large, multisite clinical trial of gabapentin enacarbil extended-release (GE-XR) (HORIZANT® ), a gabapentin prodrug formulation, to determine its safety and efficacy in treating alcohol use disorder (AUD).

METHODS:
Men and women (n= 346) who met DSM-5 criteria for at least moderate AUD were recruited across 10 US clinical sites. Participants received double-blind GE-XR (600 mg twice a day [BID]) or placebo and a computerized behavioral intervention (Take Control) for 6 months. Efficacy analyses were pre-specified for the last 4 weeks of the treatment period.

RESULTS:
The GE-XR and placebo groups did not differ significantly on the primary outcome measure, percentage of subjects with no heavy drinking days (28.3 vs 21.5, respectively, p=0.157). Similarly, no clinical benefit was found for other drinking measures (percent subjects abstinent, percent days abstinent, percent heavy drinking days, drinks per week, drinks per drinking day), alcohol craving, alcohol-related consequences, sleep problems, smoking, and depression/anxiety symptoms. Common side-effects were fatigue, dizziness, and somnolence. A population pharmacokinetics analysis revealed that patients had lower gabapentin exposure levels compared with those in other studies using a similar dose but for other indications.

CONCLUSION:
Overall, GE-XR at 600 mg BID did not reduce alcohol consumption or craving in individuals with AUD. It is possible that, unlike the IR formulation of gabapentin, which showed efficacy in smaller Phase 2 trials at a higher dose, GE-XR is not effective in treating AUD, at least not at doses approved by the FDA for treating other medical conditions.

Abstract
IMPORTANCE:
Although school environments are thought to influence health behaviors, experimental data assessing causality are lacking, and which aspects of school environments may be most important for adolescent health are unknown.

OBJECTIVE:
To test whether exposure to high-performing schools is associated with risky adolescent health behaviors.

DESIGN, SETTING, AND PARTICIPANTS:
This natural experiment used admission lotteries, which mimic random assignment, to estimate the association of school environments and adolescent health. A survey of 1270 students who applied to at least 1 of 5 high-performing public charter schools in low-income minority communities in Los Angeles, California. Schools had an academic performance ranked in the top tertile of Los Angeles County public high schools, applicants outnumbered available seats by at least 50, and an admissions lottery was used. Participants included lottery winners (intervention group [n = 694]) and lottery losers (control group [n = 576]) from the end of 8th grade and beginning of 9th grade through the end of 11th grade. Intention-to-treat (ITT) and instrumental variable techniques estimated the association of winning the lottery and attending high-performing schools with health behaviors and whether the association varied by sex. Data were collected from March 11, 2013, through February 22, 2017, and analyzed from October 1, 2017, through July 1, 2018.

EXPOSURES:
Schools were considered high performing if they placed in the top tercile of public high schools in LA County on 2012 state standardized tests. Most students attended that same school for 3 years (9th-11th grades).

MAIN OUTCOMES AND MEASURES:
Primary self-reported outcomes were 30-day and high-risk self-reported marijuana use. Additional health outcomes included 30-day alcohol use, alcohol misuse, ever being in a fight, ever having sex, and past-year delinquency. Potential intermediate factors (time studying, truancy, school mobility, school culture, school order, teacher support for college, and proportion of substance-using peers in students’ social networks) were also examined.

RESULTS:
Among the 1270 participating students (52.6% female; mean [SD] age at enrollment, 14.3 [0.5] years), ITT analysis showed that the intervention group reported less marijuana misuse than the control group (mean marijuana misuse score, 0.46 vs 0.71), as well as fewer substance-using peers (9.6% vs 12.7%), more time studying (mean, 2.63 vs 2.49 hours), less truancy (84.3% vs 77.3% with no truancy), greater teacher support for college (mean scores, 7.20 vs 7.02), more orderly schools (mean order score, 7.06 vs 6.83), and less school mobility (21.4% vs 28.4%) (all P < .05). Stratified analyses suggest that among boys, intervention participants had significantly lower marijuana use (mean misuse score, 0.43 vs 0.88; difference, -0.45; 95% CI, -0.78 to -0.13) and alcohol misuse (mean misuse score, 0.52 vs 0.97; difference, -0.44; 95% CI, -0.80 to -0.09) scores compared with control participants, whereas no significant health outcomes were noted for girls.

CONCLUSIONS AND RELEVANCE:
This natural experiment provides evidence that school environments can improve risky behaviors for low-income minority adolescents.

The Association Between Condomless Anal Sex and Social Support Among Black Men Who Have Sex With Men (MSM) in Six US Cities: A Study Using Data from the HIV Prevention Trials Network BROTHERS Study (HPTN 061). AIDS and Behavior. 2018 Oct 30:1-9.

Abstract
We assessed how egocentric (i.e., self-generated descriptions of a person’s social contacts) network structure and composition corresponded with reported instances of condomless receptive and insertive anal intercourse with men who were reportedly HIV-infected or of unknown HIV serostatus in a sample of black men who have sex with men (MSM) in six U.S. cities. Ratings showing a higher percentage of network members who provided social participation and medical support were positively associated with reporting condomless sex. There were also significant positive associations between stimulant use and condomless insertive and receptive anal sex. Future research should examine the social processes that underlie these associations and explore ways that social support can affect HIV prevention efforts for black MSM.

Building effective multilevel HIV prevention partnerships with Black men who have sex with men: experience from HPTN 073, a pre‐exposure prophylaxis study in three US cities. Journal of the International AIDS Society. 2018 Oct;21(Suppl Suppl 7).

The sub‐population at greatest risk for HIV infection in the United States is Black men who have sex with men (BMSM), and there is an urgent need for effective HIV prevention interventions among them. Despite advances in biomedical and behavioural interventions, healthcare systems continue to fail to slow the epidemic among BMSM. This is particularly the case among young men, who have an estimated lifetime risk of HIV infection of up to 50%. It has been well demonstrated that tenfovir disoproxil fumarate (TDF) and emtricitabine (FTC) as pre‐exposure prophylaxis (PrEP) are effective in protecting those at risk of HIV acquisition from sex or injection drug 4, 5, but prescriptions to BMSM have sorely lagged behind other affected populations, including gay and bisexual White men.

Gorbach PM, Javanbakht M, Shover CL, Bolan RK, Ragsdale A, Shoptaw S. Associations Between Cannabis Use, Sexual Behavior, and STIs/HIV in a Cohort of Young Men Who Have Sex with Men. Sexually transmitted diseases. 2018 Oct.

Abstract
BACKGROUND:
Among men who have sex with men (MSM) the relationship between sexually transmitted infections (STIs) and cannabis use is not well established. We assessed cannabis use, sexual behavior, and STIs including HIV in a diverse cohort of young MSM.

METHODS:
In Los Angeles the mSTUDY cohort conducted visits every 6 months with 512 MSM between 2014 and 2017 collecting demographics, sexual behaviors, and reports of frequency of substance use. Each visit conducted testing for gonorrhea, chlamydia and syphilis via blood, urine, and pharyngeal and rectal swabs by PCR, HIV was assessed using rapid tests for HIV negatives and viral load for HIV positives. We analyzed the relationship between cannabis use, sexual behaviors and STIs/HIV across 1,535 visits.

RESULTS:
Significantly fewer participants tested positive for STIs at visits when reporting the previous 6 months use of only cannabis (11.7%) compared to no drugs (16.3%) or other drugs (20.0%), (p=0.01). Fewer MSM reporting only cannabis use than no or other drug use had been incarcerated, had incarcerated partners, experienced interpersonal violence, and were HIV positive. In multivariable analyses visits with positive STIs were associated with other drug use (adjusted odds ratio (AOR) 1.69, 95% CI (1.03-2.78)) but not use of cannabis only or no drug use after controlling for age, HIV status, new sex partners, and number of sex partners.

CONCLUSIONS:
When MSM reported using cannabis exclusively fewer STIs were detected and lower risk sexual engagements reported than when MSM reported no drug or other drug use.

ABSTRACT
There is growing interest in engaging men and boys in health and development programmes targeting the intersection of HIV risk, substance abuse, and violence. Understanding the conceptualisations of masculinities or masculine identities that shape both behaviours and opportunities for intervention is central to advancing the global agenda to engage men in health and development interventions. This paper examines an intervention using soccer and job training to engage and deliver activities for HIV prevention, substance abuse, and gender-based violence in a South African township. A literature review provides theoretical, historical and social context for the intersection of gender, masculinity, soccer, violence, and sexual relationships. Qualitative data from in-depth interviews and focus groups is analysed using theoretical and contextual frames to elucidate the negotiation of shifting, contradictory, and conflicting masculine roles. Results highlight how changing risky, normative behaviours among young men is a negotiated process entailing men’s relationships with women and with other men.

From Theory to Application: A Description of Transnationalism in Culturally-Appropriate HIV Interventions of Outreach, Access, and Retention Among Latino/a Populations. Journal of immigrant and minority health. 2018 May 16:1-4.

Abstract
Interventions aiming to improve access to and retention in HIV care are optimized when they are tailored to clients’ needs. This paper describes an initiative of interventions implemented by ten demonstration sites using a transnational framework to tailor services for Mexicans and Puerto Ricans living with HIV. Transnationalism describes how immigrants (and their children) exist in their “receiving” place (e.g., continental U.S.) while simultaneously maintaining connections to their country or place of origin (e.g., Mexico). We describe interventions in terms of the strategies used, the theory informing design and the tailoring, and the integration of transnationalism. We argue how applying the transnational framework may improve the quality and effectiveness of services in response to the initiative’s overall goal, which is to produce innovative, robust, evidence-informed strategies that go beyond traditional tailoring approaches for HIV interventions with Latino/as populations.

Traditional and Web-Based Technologies to Improve Partner Notification Following Syphilis Diagnosis Among Men Who Have Sex With Men in Lima, Peru: Pilot Randomized Controlled Trial. Journal of medical Internet research. 2018 Jul;20(7).

Abstract
BACKGROUND:
Patient-initiated partner notification (PN) following the diagnosis of a sexually transmitted infection is a critical component of disease control in men who have sex with men (MSM) sexual networks. Both printed and internet-based technologies offer potential tools to enhance traditional partner notification approaches among MSM in resource-limited settings.

OBJECTIVE:
This randomized controlled trial aimed to evaluate the effect of 2 different PN technologies on notification outcomes following syphilis diagnosis among MSM in Peru: a Web-based notification system and patient-delivered partner referral cards.

METHODS:
During 2012-2014, we screened 1625 MSM from Lima, Peru, for syphilis infection and enrolled 370 MSM with symptomatic primary or secondary syphilis (n=58) or asymptomatic latent syphilis diagnosed by serology (rapid plasma reagin, RPR, and Microhemagglutination assay for Treponema pallidum antibody; n=312). Prior to enrollment, potential participants used a computer-based self-interviewing system to enumerate their recent sexual partnerships and provide details of their 3 most recent partners. Eligible participants were randomly assigned to one of 4 intervention arms: (1) counseling and patient-initiated Web-based PN (n=95), (2) counseling with Web-based partner notification and partner referral cards (n=84), (3) counseling and partner referral cards (n=97), and (4) simple partner notification counseling (control; n=94). Self-reported partner notification was assessed after 14 days among 354 participants who returned for the follow-up assessment.

RESULTS:
The median age of enrolled participants was 27 (interquartile range, IQR 23-34) years, with a median of 2 partners (IQR 1-5) reported in the past month. Compared with those who received only counseling (arm 4), MSM provided with access to Web-based partner notification (arms 1 and 2) or printed partner referral cards (arms 2 and 3) were more likely to have notified one or more of their sexual partners (odds ratio, OR, 2.18, 95% CI 1.30-3.66; P=.003 and OR 1.68, 95% CI 1.01-2.79; P=.045, respectively). The proportion of partners notified was also higher in both Web-based partner notification (241/421, 57.2%; P<.001) and referral card (240/467, 51.4%; P=.006) arms than in the control arm (82/232, 35.3%).

CONCLUSIONS:
Both new Web-based technologies and traditional printed materials support patient-directed notification and improve self-reported outcomes among MSM with syphilis. Additional research is needed to refine the use of these partner notification tools in specific partnership contexts.

Bakal DR, Coelho LE, Luz PM, Clark JL, De Boni RB, Cardoso SW, Veloso VG, Lake JE, Grinsztejn B. Obesity following ART initiation is common and influenced by both traditional and HIV-/ART-specific risk factors. Journal of Antimicrobial Chemotherapy. 2018 May 2.

Abstract
BACKGROUND:
Obesity rates are increasing among HIV-infected individuals, but risk factors for obesity development on ART remain unclear.

OBJECTIVES:
In a cohort of HIV-infected adults in Rio de Janeiro, Brazil, we aimed to determine obesity rates before and after ART initiation and to analyse risk factors for obesity on ART.

METHODS:
We retrospectively analysed data from individuals initiating ART between 2000 and 2015. BMI was calculated at baseline (time of ART initiation). Participants who were non-obese at baseline and had ≥90 days of ART exposure were followed until the development of obesity or the end of follow-up. Obesity incidence rates were estimated using Poisson regression models and risk factors were assessed using Cox regression models.

RESULTS:
Of participants analysed at baseline (n = 1794), 61.3% were male, 48.3% were white and 7.9% were obese. Among participants followed longitudinally (n = 1567), 66.2% primarily used an NNRTI, 32.9% a PI and 0.9% an integrase strand transfer inhibitor (INSTI); 18.3% developed obesity and obesity incidence was 37.4 per 1000 person-years. In multivariable analysis, the greatest risk factor for developing obesity was the use of an INSTI as the primary ART core drug (adjusted HR 7.12, P < 0.0001); other risk factors included younger age, female sex, higher baseline BMI, lower baseline CD4+ T lymphocyte count, higher baseline HIV-1 RNA, hypertension and diabetes mellitus.

CONCLUSIONS:
Obesity following ART initiation is frequent among HIV-infected adults. Key risk factors include female sex, HIV disease severity and INSTI use. Further research regarding the association between INSTIs and the development of obesity is needed.

Passaro RC, Segura ER, Perez-Brumer A, Cabeza J, Montano SM, Lake JE, Sanchez J, Lama JR, Clark JL. Body Parts Matter: Social, Behavioral, and Biological Considerations for Urethral, Pharyngeal, and Rectal Gonorrhea and Chlamydia Screening Among MSM in Lima, Peru. Sexually transmitted diseases. 2018 Sep 1;45(9):607-14.

Abstract
BACKGROUND:
Gonorrhea (Neisseria gonorrhoeae [GC]) and chlamydia (Chlamydia trachomatis [CT]) disproportionately affect men who have sex with men (MSM), and public health implications vary by anatomic site and bacterial agent. Urethral and rectal GC and CT can increase risk of HIV transmission, whereas pharyngeal GC may be a reservoir for antimicrobial resistance. To define screening priorities in Latin America, we compare differences in the prevalence and correlates of urethral, pharyngeal, and rectal GC and CT among MSM in Peru.

METHODS:
A cross-sectional sample of 787 MSM from Lima was screened between 2012 and 2014. We described prevalence of urethral, pharyngeal, and rectal GC and CT infection and conducted bivariate analyses of associations with social, behavioral, and biological characteristics. Poisson regression analyses assessed the correlates of each infection at each anatomic site.

RESULTS:
The most commonly symptomatic infection (urethral GC; 42.1%) was the least prevalent (2.4%). The most prevalent infections were rectal CT (15.8%) and pharyngeal GC (9.9%). Rectal CT was the least commonly symptomatic (2.4%) infection, and was associated with younger age (adjusted prevalence ratio [95% confidence interval], 0.96 [0.94-0.98]), HIV infection (1.46 [1.06-2.02]), and pasivo (receptive; 3.59 [1.62-7.95]) and moderno (versatile; 2.63 [1.23-5.60]) sexual roles.

CONCLUSIONS:
Results highlight limitations of current syndromic screening strategies for sexually transmitted diseases in Peru, wherein urethral CT and rectal GC and CT may be missed due to their frequently asymptomatic presentations. Successful management of GC and CT infections among MSM in low-resource settings requires differentiating between bacterial agent, symptomatic presentation, associated risk factors, and public health implications of untreated infection at different anatomic sites.

Individual and partnership factors associated with anticipated versus actual partner notification following STI diagnosis among men who have sex with men and/or with transgender women in Lima, Peru. Sex Transm Infect. 2018 Dec 1;94(8):607-10.

Abstract
OBJECTIVES:
A detailed understanding of intentions and practices related to partner notification (PN) following STI diagnosis can improve control strategies. We assessed participant-level and partner-level factors guiding notification behaviour among men who have sex with men and/or with transgender women (MSM-TW) in Lima, Peru, including discordances between anticipated and actual notification.

METHODS:
Men newly diagnosed with gonorrhoea, chlamydia and/or syphilis between 2012 and 2014 reported recent partners’ characteristics, anticipated PN practices, and actual PN outcomes following diagnosis. Generalised estimating equation Poisson regression analyses assessed factors guiding PN outcomes.

RESULTS:
Participants (n=150) predominantly identified as homosexual (70%) and moderno (versatile sexual role, 55%); 55% of partners (n=402) were casual. Among all sexual partners, 35% were notified of the STI diagnosis, though only 51% of predicted PN occurred and 26% of actual notifications were unanticipated. 47% of participants notified no partners, while 24% notified all partners. PN was more common with stable versus casual (adjusted prevalence ratio (aPR), 95% CI: 0.53, 0.39 to 0.73) or commercial (aPR, 95% CI: 0.38, 0.12 to 1.21) partners, and among participants who perceived PN as normative among their peers (aPR, 95% CI: 1.96, 1.37 to 2.82). A trend towards greater notification following condom-protected intercourse was observed (aPR, 95% CI: 1.33, 0.98 to 1.81). PN frequency did not differ by type of STI diagnosed.Anticipated notification predicted actual notification (aPR, 95% CI: 1.67, 1.19 to 2.33) only imperfectly: 81 (54%) participants’ PN practices did not match their anticipated behaviour. Successful notification despite anticipated silence (40 participants, 63 partners) was associated with stable partnerships and a normative perception of PN. Non-notification despite intention (43 participants, 73 partners) frequently occurred among participants reporting exclusively oral sex with the partner or with partners identified as activo (insertive role).

CONCLUSIONS:
Anticipated notification imperfectly reflects actual PN behaviour. Future interventions to improve PN among MSM-TW in Peru need to acknowledge partnership contexts.

Abstract
Background
Human immunodeficiency virus type 1 (HIV-1) infection alters the human intestinal microbiome; however, behavioral factors driving these changes remain poorly defined. Here we examine the effects of substance use and sex behavior on the microbiome during HIV-1 infection.

Methods
Archival rectal swab specimens, urine drug test results, and responses to substance use and sex behavior questionnaires were obtained from 37 HIV-positive participants at 2 time points, separated by 6 months, in a cohort examining the effects of substance use in men who have sex with men (MSM). Microbiome profiling was performed using 16S ribosomal RNA gene sequencing, and associations with behavioral factors were examined using 0-inflated negative binomial regression. Further analysis of selected variables of interest was performed using propensity scores to account for multiple confounders.

Results
Using permutational multivariate analysis of variance, we found that receptive anal intercourse, methamphetamine use, and marijuana use were among the most important drivers of microbiome variation. Propensity score–adjusted analyses revealed that methamphetamine use and marijuana use displayed unique associations; methamphetamine use was associated with an increased abundance of Porphyromonas and Granulicatella organisms and a decreased abundance of Ruminococcus, Collinsella, and Parabacteroides organisms, whereas marijuana use was associated with an increased abundance of Ruminococcus, Clostridium cluster IV, Solobacterium, and Fusobacterium organisms and a decreased abundance of Acidaminococcus, Prevotella, Dialister, Anaerostipes, and Dorea organisms.

Conclusions
Drug use and sex behavior are important factors associated with intestinal dysbiosis during chronic HIV-1 infection among young MSM.

Abstract
BACKGROUND:
Black men who have sex with men (BMSM) and some who also have sex with women (BMSMW) account for over 70% of new HIV infections in the United States representing an elevated HIV risk in this group, also informing risks of HIV transmission to other BMSM and female sexual partners.

SETTINGS:
We examined trajectories of self-reported substance use, HIV-related sexual risk behaviors, and psychosocial vulnerabilities among BMSMW versus BMSM over a 1-year study period.

METHODS:
We analyzed baseline, 6-, and 12-month follow-up data from the HIV Prevention Trials Network “BROTHERS” Study (HPTN 061; n = 1126). Categorizing participants by sexual partner type across 3 time points: (1) BMSMO: having male and no female partners across assessments and (2) BMSMW: having sex with male and one or more female partners at least at 1 time point. Using generalized estimating equations, we estimated associations between being BMSMW (versus BMSMO) and changes in psychosocial vulnerability, substance use, and HIV-related sexual risk behaviors.

RESULTS:
Generalized estimating equation models controlling for sociodemographics, time-varying effects, and intervention status showed that BMSMW versus BMSMO had 50% increased odds of crack use, 71% increased odds of alcohol use during condomless anal intercourse (CAI), 51% greater odds of using drugs at last CAI, and twice the odds of receiving goods at last CAI.

CONCLUSIONS:
Findings show stable and comparatively elevated illicit drugs, alcohol, and exchange sex during last CAI among BMSMW. Future intervention research should focus on ways to address changes in substance-related HIV-transmission behaviors over time in this population of men.

Abstract
Stimulant use may accelerate HIV disease progression through biological and behavioral pathways. However, scant research with treated HIV-positive persons has examined stimulant-associated alterations in pathophysiologic processes relevant to HIV pathogenesis. In a sample of 55 HIV-positive, methamphetamine-using sexual minority men with a viral load less than 200 copies/mL, we conducted RNA sequencing to examine patterns of leukocyte gene expression in participants who had a urine sample that was reactive for stimulants (n = 27) as compared to those who tested non-reactive (n = 28). Results indicated differential expression of 32 genes and perturbation of 168 pathways in recent stimulant users. We observed statistically significant differential expression of single genes previously associated with HIV latency, cell cycle regulation, and immune activation in recent stimulant users (false discovery rate p < 0.10). Pathway analyses indicated enrichment for genes associated with inflammation, innate immune activation, neuroendocrine hormone regulation, and neurotransmitter synthesis. Recent stimulant users displayed concurrent elevations in plasma levels of tumor necrosis factor – alpha (TNF-α) but not interleukin 6 (IL-6). Further research is needed to examine the bio-behavioral mechanisms whereby stimulant use may contribute to HIV persistence and disease progression.

Abstract
OBJECTIVES:
To characterize uptake of HIV preexposure prophylaxis (PrEP) in a community setting and to identify disparities in PrEP use by demographic and behavioral factors associated with increased HIV risk.

METHODS:
We conducted a cross-sectional study of 19 587 men who have sex with men and transgender people visiting a Los Angeles, California, clinic specializing in lesbian, gay, bisexual, and transgender care between August 2015 and February 2018 by using clinical care data.

RESULTS:
Seventy percent of patients met PrEP eligibility criteria, while 10% reported PrEP use. Using sex drugs, reporting both condomless anal intercourse and recent sexually transmitted infection, older age, and higher education level were associated with higher odds of PrEP use given eligibility. Latino or Asian race/ethnicity and bisexual orientation were associated with lower odds of PrEP use given eligibility. Higher odds of perceived need were associated with demographic risk factors but PrEP use was not similarly elevated.

CONCLUSIONS:
Discrepancies between PrEP eligibility, perceived need, and use reveal opportunities to improve PrEP delivery in community settings. Public Health Implications. Efforts are needed to facilitate PrEP uptake in populations with highest HIV incidence.

Abstract
OBJECTIVE:
Primary care (PC) is a major service delivery setting that can provide preventive behavioral health care to youths. To explore the hypothesis that reducing health risk behaviors (HRBs) would lower depressive symptoms, and that health risk and depression can be efficiently targeted together in PC, this study (1) evaluates an intervention designed to reduce HRBs among adolescent PC patients with depressive symptoms and (2) examines prospective links between HRBs and depressive symptoms.

METHOD:
A Randomized controlled trial was conducted comparing a behavioral health intervention with enhanced Usual PC (UC+). Participants were 187 adolescents (ages 13-18 years) with past-year depression, assessed at baseline, 6 months, and 12 months. Primary outcome was the Health Risk Behavior Index (HRBI), a composite score indexing smoking, substance use, unsafe sex, and obesity risk. Secondary/exploratory outcomes were an index of the first three most correlated behaviors (HRBI-S), each HRB, depressive symptoms, and satisfaction with mental health care.

RESULTS:
Outcomes were similar at 6 and 12 months, with no significant between-group differences. HRBI, HRBI-S, and depressive symptoms decreased, and satisfaction with mental health care increased across time in both groups. HRBI, HRBI-S, and smoking predicted later severe depression. Conversely, severe depression predicted later HRBI-S and substance use.

CONCLUSIONS:
UC+ and the behavioral health intervention yielded similar benefits in reducing HRBs and depressive symptoms. Findings underscore the bidirectional links between depression and HRBs, supporting the importance of monitoring for HRBs and depression in PC to allow for effective intervention in both areas.

Abstract
BACKGROUND:
Contingency management (CM) is an evidence-based intervention providing rewards in exchange for biomarkers that confirm abstinence from stimulants such as methamphetamine. We tested the efficacy of a positive affect intervention designed to boost the effectiveness of CM with HIV-positive, methamphetamine-using sexual minority men.

METHODS:
This attention-matched, randomized controlled trial of a positive affect intervention delivered during CM was registered on www.clinicaltrials.gov (NCT01926184). In total, 110 HIV-positive sexual minority men with biologically confirmed, recent methamphetamine use were enrolled. Five individual sessions of a positive affect intervention (n = 55) or an attention-control condition (n = 55) were delivered during three months of CM. Secondary outcomes examined over the 3-month intervention period included: 1) psychological processes relevant to affect regulation (i.e., positive affect, negative affect, and mindfulness); 2) methamphetamine craving; 3) self-reported stimulant use (past 3 months); and 4) cumulative number of urine samples that were non-reactive for stimulants (i.e., methamphetamine and cocaine) during CM.

RESULTS:
Those randomized to the positive affect intervention reported significant increases in positive affect during individual sessions and increases in mindfulness over the 3-month intervention period. Intervention-related improvements in these psychological processes relevant to affect regulation were paralleled by concurrent decreases in methamphetamine craving and self-reported stimulant use over the 3-month intervention period.

CONCLUSIONS:
Delivering a positive affect intervention may improve affect regulation as well as reduce methamphetamine craving and stimulant use during CM with HIV-positive, methamphetamine-using sexual minority men.

Building the Case for Localized Approaches to HIV: Structural Conditions and Health System Capacity to Address the HIV/AIDS Epidemic in Six US Cities. AIDS and Behavior. 2018 May 25:1-2. PMCID: PMC6076864

Abstract
Since the discovery of the secondary preventive benefits of antiretroviral therapy, national and international governing bodies have called for countries to reach 90% diagnosis, ART engagement and viral suppression among people living with HIV/AIDS. The US HIV epidemic is dispersed primarily across large urban centers, each with different underlying epidemiological and structural features. We selected six US cities, including Atlanta, Baltimore, Los Angeles, Miami, New York, and Seattle, with the objective of demonstrating the breadth of epidemiological and structural differences affecting the HIV/AIDS response across the US. We synthesized current and publicly-available surveillance, legal statutes, entitlement and discretionary funding, and service location data for each city. The vast differences we observed in each domain reinforce disparities in access to HIV treatment and prevention, and necessitate targeted, localized strategies to optimize the limited resources available for each city’s HIV/AIDS response.

Associations of Emotional, Physical, or Sexual Intimate Partner Violence and Depression Symptoms Among South African Women in a Prospective Cohort Study. Journal of interpersonal violence. 2018 Aug 30:0886260518796522. PMID: 30160637

Abstract
Violence against women remains a significant public health problem globally. The majority of longitudinal studies documenting the negative impact of intimate partner violence (IPV) on the mental health of women come from high-income countries. The aim of this study was to investigate the longitudinal association between emotional, physical, or sexual IPV and depression symptoms among South African women in a prospective cohort study. Participants were 981 South African women enrolled in the Drakenstein Child Health Study-a cohort study investigating the early life determinants of child health. Interview data from four time-points (antenatal care visit, 6 months, 12 months, and 18 months postpartum) were included. The primary independent variable was self-reported emotional, physical, and sexual IPV in the past 12 months. Depressive symptoms were assessed at each time-point with the Edinburgh Postnatal Depression Scale (EPDS); a cutoff score of ⩾13 was used to define significant depression symptoms. We used pooled-multivariable logistic regression models to determine associations between the three different forms of IPV and significant depression symptoms while adjusting for time-fixed and time-updated covariates. The mean age of the sample at antenatal care visit was 27 years (standard deviation = 6.0). In the adjusted model including all forms of IPV and adjusting for sociodemographic and clinical characteristics, substance use, and childhood trauma, emotional (adjusted odds ratio [aOR] =1.55, 95% confidence interval (CI): [1.02, 2.34]; p = .039)] and sexual (aOR = 2.02, 95% CI: [1.10, 3.72]; p < .001) IPV were significantly associated with significant depression symptoms. The relationship between physical IPV and significant depression symptoms was not statistically significant (aOR = 0.68, 95% CI: [0.44, 1.05]; p = .485). Our study confirms findings from high-income countries of the association between IPV and depressive symptoms among women in South Africa. Routine screening for IPV, including emotional IPV and intervention programs for IPV among women, is needed in South Africa.

Abstract
Young men in South Africa experience several adverse socio-structural and psychosocial factors that may contribute HIV risk behaviors. This study applied a syndemic framework to explore whether these syndemic factors are interconnected and work in synergy to increase HIV risk behaviors. Five syndemic factors were assessed including: binge drinking, polydrug use, depressive symptoms, violence and food insecurity on two HIV risk behaviors: multiple sex partners and transactional sex. Participants were (N = 1233) young men aged 18-29 years from a township in Cape Town, South Africa. Bivariate logistic regression analysis demonstrated that many of the syndemic factors were related to one another. Pairwise interactions (on an additive scale) among the syndemic factors revealed significant positive interactions between binge drinking and violence on greater odds of reporting multiple sex partners (aOR = 5.10, 95% CI 3.10, 8.29; p = < .001) compared to reporting neither factor. Also, food insecurity and violence (aOR = 2.89, 95% CI 1.63, 5.11; p = < .001) as well as food insecurity and polydrug use (aOR = 2.73, 95% CI 1.54, 4.84; p = < .001) were significantly associated with greater odds of transactional sex compared to reporting neither factor. Our findings highlight a synergistic relationship between some adverse socio-structural and psychosocial factors on HIV risk behaviors. HIV prevention programs that address multiple syndemic factors simultaneously may achieve greater impact on HIV risk reduction.

Effectiveness of a peer navigation intervention to sustain viral suppression among HIV-positive men and transgender women released from jail: the LINK LA randomized clinical trial. JAMA internal medicine. 2018 Apr 1;178(4):542-53. PMCID: PMC5885257

Abstract
IMPORTANCE:
Diagnosis of human immunodeficiency virus (HIV) infection, linkage and retention in care, and adherence to antiretroviral therapy are steps in the care continuum enabling consistent viral suppression for people living with HIV, extending longevity and preventing further transmission. While incarcerated, people living with HIV receive antiretroviral therapy and achieve viral suppression more consistently than after they are released. No interventions have shown sustained viral suppression after jail release.

OBJECTIVE:
To test the effect on viral suppression in released inmates of the manualized LINK LA (Linking Inmates to Care in Los Angeles) peer navigation intervention compared with standard transitional case management controls.

DESIGN, SETTING, AND PARTICIPANTS:
Randomized clinical trial conducted from December 2012 through October 2016 with people living with HIV being released from Los Angeles (LA) County Jail. All participants were (1) 18 years or older; (2) either men or transgender women diagnosed with HIV; (3) English speaking; (4) selected for the transitional case management program prior to enrollment; (5) residing in LA County; and (6) eligible for antiretroviral therapy.

MAIN OUTCOMES AND MEASURES:
Change in HIV viral suppression (<75 copies/mL) over a 12-month period.

INTERVENTIONS:
During the 12-session, 24-week LINK LA Peer Navigation intervention, trained peer navigators counseled participants on goal setting and problem solving around barriers to HIV care and adherence, starting while the participants were still in jail. After their release, they continued counseling while they accompanied participants to 2 HIV care visits, then facilitated communication with clinicians during visits.

RESULTS:
Of 356 participants randomized, 151 (42%) were black; 110 (31%) were Latino; 303 (85%) were men; 53 (15%) were transgender women; and the mean (SD) age was 39.5 (10.4) years. At 12 months, viral suppression was achieved by 62 (49.6%) of 125 participants in the peer navigation (intervention) arm compared with 45 (36.0%) of 125 in the transitional case management (control) arm, for an unadjusted treatment difference of 13.6% (95% CI, 1.34%-25.9%; P = .03). In the repeated measures, random effects, logistic model the adjusted probability of viral suppression declined from 52% at baseline to 30% among controls, while those in the peer navigation arm maintained viral suppression at 49% from baseline to 12 months, for a difference-in-difference of 22% (95% CI, 0.03-0.41; P = .02).

CONCLUSIONS AND RELEVANCE:
The LINK LA peer navigation intervention was successful at preventing declines in viral suppression, typically seen after release from incarceration, compared with standard transitional case management. Future research should examine ways to strengthen the intervention to increase viral suppression above baseline levels.

Abstract

BACKGROUND AND AIMS:
High rates of loss to follow-up represent a significant challenge to clinical trials of pharmacological treatments for methamphetamine (MA) use disorder. We aimed to estimate and test the relationship between achieving and maintaining abstinence in the initial weeks of study participation and subsequent retention in such trials, hypothesizing that participants able to achieve early abstinence would be less likely to drop out.

DESIGN:
Data from four randomized controlled trials (RCTs) of pharmacological treatments for MA use disorder were pooled and analyzed using a random-effects approach.

SETTING:
All trials were conducted in the greater Los Angeles, CA, USA area.

PARTICIPANTS:
A total of 440 participants were included; trials were conducted between 2004 and 2014.

MEASUREMENTS:
Participants’ ability to achieve a brief period of initial abstinence was measured as the number of MA-negative urine screens completed in the first 2 weeks of the trials. Outcomes were the likelihood of dropout, i.e. missing two consecutive weeks of scheduled urine drug screens, and the number of days participants were retained in the trials.

FINDINGS:
Study participants achieved an average of three (of six possible) negative urine screens during the first 2 weeks of the trials, 51% dropped out and the average number of days retained was 60 (of 90 maximum). Each additional negative urine screen achieved during the first 2 weeks of the study reduced multiplicatively the odds of dropout by 41% [odds ratio (OR) = 0.59, 95% confidence interval (CI) = 0.53, 0.66]. Abstinence was also a significant predictor of retention time; the hazard ratio for non-completion was 0.75 per additional negative urine screen (95% CI = 0.71, 0.80).

CONCLUSIONS:
Participants in randomized controlled trials of pharmacological treatments for methamphetamine use disorder who are able to achieve a brief period of early abstinence are retained longer in the trials and are less likely to drop out overall.

A Longitudinal Analysis of Treatment Optimism and HIV Acquisition and Transmission Risk Behaviors Among Black Men Who Have Sex with Men in HPTN 061. AIDS Behavior. October 2017, Volume 21, Issue 10, pp 2958–2972. PMCID: PMC5623129

Abstract

Little is known about HIV treatment optimism and risk behavioral among Black men who have sex with men (BMSM). Using longitudinal data from BMSM in the HPTN 061 study, we examined participants’ self-reported comfort with having condomless sex due to optimistic beliefs regarding HIV treatment. We assessed correlates of treatment optimism and its association with subsequent risk behaviors for HIVacquisition or transmission using multivariable logistic regression with generalized estimating equations. Independent correlates of treatmentoptimism included age ≥35 years, annual household income <$20,000, depressive symptoms, high HIV conspiracy beliefs, problematic alcohol use, and previous HIV diagnosis. Treatment optimism was independingly associated with subsequent condomless anal sex with a male partner of serodiscordant/unknown HIV status among HIV-infected men, but this association was not statistically significant among HIV-uninfected men. HIV providers should engage men in counseling conversations to assess and minimize willingness to have condomless sexthat is rooted in optimistic treatment beliefs without knowledge of viral suppression.

Abstract

We assessed socio-structural and behavioral correlates of preexposure prophylaxis (PrEP) for HIV infection among a sample of high-risk HIV-negative men who have sex with men (MSM) in Los Angeles, California. Participants from an ongoing 5-year prospective cohort study investigating the direct impacts of substance use on HIV transmission dynamics were enrolled between February 2015 and January 2017. All men completed a computer-assisted self-interview every 6 months that assessed recent (past 6 months) PrEP use and socio-structural and behavioral factors. Of the total 185 MSM (mean age = 29 years) included in the study, majority were African American (40%) or Hispanic (41%) and reported current health insurance coverage (80%). In multivariable analysis using log-binomial regression, having health insurance coverage [adjusted prevalence ratio (aPR) 2.02; 95% confidence interval (CI) 1.01 to 4.01, p = 0.04] was associated with recent PrEP use. Unstable housing (aPR = 0.44, 95% CI 0.22 to 0.90, p = 0.02) was associated with lower PrEP use. Behavioral factors associated with recent PrEP use include sex with a HIV-positive partner (aPR = 3.63, 95% CI 1.45 to 9.10, p = 0.01), having six or more sex partners (aPR = 2.20, 95% CI 1.26 to 3.82, p = <0.01), and popper use (aPR = 2.76, 95% CI 1.58 to 4.84, p = <0.01). In this sample of predominantly racial/ethnic minority MSM, socio-structural and behavioral factors were important factors associated with recent PrEP use. These findings provide considerations for intervention development to promote PrEP use among key groups of MSM.

Perceived barriers and facilitators to integrating HIV prevention and treatment with cross-sex hormone therapy for transgender women in Lima, Peru. AIDS and Behavior. 2017 Dec 1;21(12):3299-311. PMCID: PMC5647197.

Abstract
Transgender women (TW) represent a vulnerable population at increased risk for HIV infection in Peru. A mixed-methods study with 48 TW and 19 healthcare professionals was conducted between January and February 2015 to explore barriers and facilitators to implementing a model of care that integrates HIV services with gender-affirmative medical care (i.e., hormone therapy) in Lima, Peru. Perceived acceptability of the integrated care model was high among TW and healthcare professionals alike. Barriers included stigma, lack of provider training or Peruvian guidelines regarding optimal TW care, and service delivery obstacles (e.g., legal documents, spatial placement of clinics, hours of operation). The hiring of TW staff was identified as a key facilitator for engagement in health care. Working in partnership with local TW and healthcare provider organizations is critical to overcoming existing barriers to successful implementation of an integrated HIV services and gender-affirmative medical care model for this key population in Peru.

Abstract

BACKGROUND:
Inattention is a deficit related to instilling abstinence from methamphetamine (MA) dependence. This study aimed to determine whether ibudilast (IB; 50mg bid) improves attentional abilities compared to placebo during early abstinence from MA dependence.

METHODS:
Attention was assessed in 11 MA-dependent non-treatment seeking participants in a phase IB safety-interaction trial. The Conners’ Continuous Performance Test-II (CPT-II), a measure of sustained attention and response inhibition, was administered at baseline and on day 22, 48h post a MA challenge under placebo (P; n=6) or IB 50mg bid (n=5). Group differences were compared using Mann-Whitney U Tests. Groups were similar at baseline in premorbid intellectual functioning, attention deficit hyperactivity symptom scores, impulsivity ratings, and education level, but differed in age. Demographically corrected T-scores for CPT-II performances were utilized.

RESULTS:
Although no group differences in sustained attention existed at baseline, at follow-up, the IB group (Mdn=44.4) showed reduced variability in response times compared with the P group (Mdn=69.9), U=0.00, z=-2.74, p=.006, r=.83. The IB group (Mdn=45.8) also gave fewer perseverative responses than the P group (Mdn=67.0), U=2.00, z=-2.50, p=.01, r=.75. No other significant differences were observed.

CONCLUSIONS:
Findings suggest that IB may have a protective effect on sustained attention during early abstinence from MA dependence. This may guide thinking about mechanism of action should IB demonstrate efficacy as a treatment for MA dependence.

Abstract
Current directions in medication development for alcohol use disorder (AUD) emphasize the need to identify novel molecular targets and efficiently screen new compounds aimed at those targets. Ibudilast (IBUD) is a neuroimmune modulator that inhibits phosphodiesterase-4 and -10 and macrophage migration inhibitory factor and was recently found to reduce alcohol intake in rats by ∼50%. To advance medication development for AUD, the present study consists of a randomized, crossover, double-blind, placebo-controlled laboratory study of IBUD in nontreatment-seeking individuals with current (ie, past month) mild-to-severe AUD. This study tested the safety, tolerability, and initial human laboratory efficacy of IBUD (50 mg b.i.d.) on primary measures of subjective response to alcohol as well as secondary measures of cue- and stress-induced changes in craving and mood. Participants (N=24) completed two separate 7-day intensive outpatient protocols that included daily visits for medication administration and testing. Upon reaching a stable target dose of IBUD (or matched placebo), participants completed a stress-exposure session (day 5; PM), an alcohol cue-exposure session (day 6; AM), and an i.v. alcohol administration session (day 6; PM). Participants stayed overnight after the alcohol administration, and discharge occurred on day 7 of the protocol. Medication conditions were separated by a washout period that was ⩾7 days. IBUD was well tolerated; however, there were no medication effects on primary measures of subjective response to alcohol. IBUD was associated with mood improvements on the secondary measures of stress exposure and alcohol cue exposure, as well as reductions in tonic levels of craving. Exploratory analyses revealed that among individuals with higher depressive symptomatology, IBUD attenuated the stimulant and mood-altering effects of alcohol as compared with placebo. Together, these findings extend preclinical demonstrations of the potential utility of IBUD for the treatment of AUD and suggest that depressive symptomatology should be considered as a potential moderator of efficacy for pharmacotherapies with neuroimmune effects, such as IBUD.

Analysis of HIV integrase resistance in Black men who have sex with men in the United States. AIDS Research and Human Retroviruses. July 2017. 33(7): 745-748.

Abstract/Summary:

Resistance to reverse transcriptase and protease inhibitors was frequently detected in HIV from black men who have sex with men (MSM) enrolled in the HIV prevention trials network (HPTN) 061 study. In this study, integrase strand transfer inhibitor (INSTI) resistance was analyzed in black MSM enrolled in HPTN 061 (134 infected at enrollment and 23 seroconverters) and a follow-up study, HPTN 073 (eight seroconverters). The ViroSeq HIV-1 Integrase Genotyping Kit (Abbott Molecular) was used for analysis. Major INSTI resistance mutations were not detected in any of the samples. HIV from 14 (8.4%) of the 165 men, including 4 (12.9%) of 31 seroconverters, had accessory or polymorphic INSTI-associated mutations. The most frequently detected mutation was E157Q. These findings are promising because INSTI-based regimens are now recommended for first-line antiretroviral treatment and because long-acting cabotegravir is being evaluated for pre-exposure prophylaxis.

ABSTRACT
Despite current prevention efforts, HIV incidence continues to rise among young men who have sex with men (YMSM) in the United States. Identification of new infections through routine testing is an important first step in the HIV treatment cascade; behavioral assessment among those who test negative may prompt deployment of new biomedical prevention efforts. The present study interviewed 100 YMSM (mean age 25) in Los Angeles, California, with the goal of identifying and understanding HIV testing beliefs and behaviors. Analysis of responses to brief semistructured interviews was conducted using content analysis. Findings highlight high rates of testing (91% lifetime tested; 59% in past 6 months) but reveal a disconnect between HIV testing and risk assessment. Partnerships between academic institutions, community-based organizations, and individual practitioners may facilitate community-wide HIV testing complemented by biomedical interventions. Further exploration of YMSM’s attitudes toward HIV testing is warranted.

Abstract/Summary:

Purpose: Cigarette smoking is a preventable risk factor that contributes to unnecessary lung cancer burden among Korean Americans and there is limited research on effective smoking cessation strategies for this population. Smartphone-based smoking cessation apps that leverage just-in-time adaptive interventions (JITAIs) hold promise for smokers attempting to quit. However, little is known about how to develop and tailor a smoking cessation JITAI for Korean American emerging adult (KAEA) smokers.

Method: This paper documents the development process of MyQuit USC according to design guidelines for JITAI. Our development process builds on findings from a prior ecological momentary assessment study by using qualitative research methods. Semi-structured interviews and a focus group were conducted to inform which intervention options to offer and the decision rules that dictate their delivery.

Results: Qualitative findings highlighted that (1) smoking episodes are highly context-driven and that (2) KAEA smokers believe they need personalized cessation strategies tailored to different contexts. Thus, MyQuit USC operates via decision rules that guide the delivery of personalized implementation intentions, which are contingent on dynamic factors, to be delivered “just in time” at user-scheduled, high-risk smoking situations.

Conclusion: Through an iterative design process, informed by quantitative and qualitative formative research, we developed a smoking cessation JITAI tailored specifically for KAEA smokers. Further testing is under way to optimize future versions of the app with the most effective intervention strategies and decision rules. MyQuit USC has the potential to provide cessation support in real-world settings, when KAEAs need them the most.

Kitayama K, Segura ER, Lake JE, Perez-Brumer AG, Oldenburg CE, Myers BA, Pourjavaheri P, Okorie CN, Cabello RL, Clark JL. Syphilis in the Americas: a protocol for a systematic review of syphilis prevalence and incidence in four high-risk groups, 1980–2016. Systematic reviews. 2017 Dec;6(1):195.

Abstract
BACKGROUND:
Syphilis infection has recently resurfaced as a significant public health problem. Although there has been a tremendous amount of research on the epidemiology of syphilis, there has been limited work done to synthesize the extensive body of research and systematically estimate patterns of disease within high-risk groups in the Americas. The purpose of this systematic review and meta-analysis is to (1) summarize recent patterns of syphilis infection in North and South America among four high-risk groups (MSM, transgender women, sex workers, and incarcerated individuals) from 1980 to 2016, (2) identify and differentiate regional geographic epidemiologic characteristics, and (3) compare the epidemics of the economically developed countries of North America from the developing countries and public health systems of Latin America and the Caribbean.

METHODS/DESIGN:
Primary studies reporting syphilis prevalence and/or incidence in at least one of the four high-risk groups will be identified from Medline/PubMed, Embase, Lilacs, SciELO, The Cochrane Library, Web of Science, Scopus, ProQuest, CINAHL, Clase, and Periódica, as well as “gray” literature sources (conference abstracts, country reports, etc.). Studies published from 1980 through 2016 will be included. Data will be extracted from studies meeting inclusion and exclusion criteria and a random effects meta-analysis of prevalence and incidence estimates will be conducted. Heterogeneity, risk of bias, and publication bias will be assessed. Pooled prevalence and incidence estimates will be calculated for comparisons based on geographic region, risk factors, and time period.

DISCUSSION:
Our systematic review and meta-analysis aims to contribute to an improved understanding of global epidemiologic patterns of syphilis infection in most-at-risk populations. Through systematic classification of the existing literature, and comparison of disease patterns across regional, temporal and socio-behavioral differences, we hope to improve public health surveillance and improve efforts to control the spread of disease across the Americas.

Braun HM, Segura ER, Lake JE, Gandhi M, Rios J, Villaran MV, Sanchez J, Lama JR, Clark JL. Individual and partnership factors associated with anticipated versus actual partner notification following STI diagnosis among men who have sex with men and/or with transgender women in Lima, Peru. Sex Transm Infect. 2017 Nov 30. pii: sextrans-2017-053292. PMCID: PMC5976515.

Abstract
OBJECTIVES:
A detailed understanding of intentions and practices related to partner notification (PN) following STI diagnosis can improve control strategies. We assessed participant-level and partner-level factors guiding notification behaviour among men who have sex with men and/or with transgender women (MSM-TW) in Lima, Peru, including discordances between anticipated and actual notification.

METHODS:
Men newly diagnosed with gonorrhoea, chlamydia and/or syphilis between 2012 and 2014 reported recent partners’ characteristics, anticipated PN practices, and actual PN outcomes following diagnosis. Generalised estimating equation Poisson regression analyses assessed factors guiding PN outcomes.

RESULTS:
Participants (n=150) predominantly identified as homosexual (70%) and moderno (versatile sexual role, 55%); 55% of partners (n=402) were casual. Among all sexual partners, 35% were notified of the STI diagnosis, though only 51% of predicted PN occurred and 26% of actual notifications were unanticipated. 47% of participants notified no partners, while 24% notified all partners. PN was more common with stable versus casual (adjusted prevalence ratio (aPR), 95% CI: 0.53, 0.39 to 0.73) or commercial (aPR, 95% CI: 0.38, 0.12 to 1.21) partners, and among participants who perceived PN as normative among their peers (aPR, 95% CI: 1.96, 1.37 to 2.82). A trend towards greater notification following condom-protected intercourse was observed (aPR, 95% CI: 1.33, 0.98 to 1.81). PN frequency did not differ by type of STI diagnosed.Anticipated notification predicted actual notification (aPR, 95% CI: 1.67, 1.19 to 2.33) only imperfectly: 81 (54%) participants’ PN practices did not match their anticipated behaviour. Successful notification despite anticipated silence (40 participants, 63 partners) was associated with stable partnerships and a normative perception of PN. Non-notification despite intention (43 participants, 73 partners) frequently occurred among participants reporting exclusively oral sex with the partner or with partners identified as activo (insertive role).

CONCLUSIONS:
Anticipated notification imperfectly reflects actual PN behaviour. Future interventions to improve PN among MSM-TW in Peru need to acknowledge partnership contexts.

Watkins KE, Ober AJ, Lamp K, Lind M, Setodji C, Osilla KC, Hunter SB, McCullough CM, Becker K, Iyiewuare PO, Diamant A, Heinzerling K, Pincus HA. Collaborative care for opioid and alcohol use disorders in primary care: the SUMMIT randomized clinical trial. JAMA Internal Medicine. 2017 Oct 1;177(10):1480-8. PMCID: PMC5710213.

Abstract
IMPORTANCE:
Primary care offers an important and underutilized setting to deliver treatment for opioid and/or alcohol use disorders (OAUD). Collaborative care (CC) is effective but has not been tested for OAUD.

OBJECTIVE:
To determine whether CC for OAUD improves delivery of evidence-based treatments for OAUD and increases self-reported abstinence compared with usual primary care.

DESIGN, SETTING, AND PARTICIPANTS:
A randomized clinical trial of 377 primary care patients with OAUD was conducted in 2 clinics in a federally qualified health center. Participants were recruited from June 3, 2014, to January 15, 2016, and followed for 6 months.

INTERVENTIONS:
Of the 377 participants, 187 were randomized to CC and 190 were randomized to usual care; 77 (20.4%) of the participants were female, of whom 39 (20.9%) were randomized to CC and 38 (20.0%) were randomized to UC. The mean (SD) age of all respondents at baseline was 42 (12.0) years, 41(11.7) years for the CC group, and 43 (12.2) yearsfor the UC group. Collaborative care was a system-level intervention, designed to increase the delivery of either a 6-session brief psychotherapy treatment and/or medication-assisted treatment with either sublingual buprenorphine/naloxone for opioid use disorders or long-acting injectable naltrexone for alcohol use disorders. Usual care participants were told that the clinic provided OAUD treatment and given a number for appointment scheduling and list of community referrals.

MAIN OUTCOMES AND MEASURES:
The primary outcomes were use of any evidence-based treatment for OAUD and self-reported abstinence from opioids or alcohol at 6 months. The secondary outcomes included the Healthcare Effectiveness Data and Information Set (HEDIS) initiation and engagement measures, abstinence from other substances, heavy drinking, health-related quality of life, and consequences from OAUD.

RESULTS:
At 6 months, the proportion of participants who received any OAUD treatment was higher in the CC group compared with usual care (73 [39.0%] vs 32 [16.8%]; logistic model adjusted OR, 3.97; 95% CI, 2.32-6.79; P < .001). A higher proportion of CC participants reported abstinence from opioids or alcohol at 6 months (32.8% vs 22.3%); after linear probability model adjustment for covariates (β = 0.12; 95% CI, 0.01-0.23; P = .03). In secondary analyses, the proportion meeting the HEDIS initiation and engagement measures was also higher among CC participants (initiation, 31.6% vs 13.7%; adjusted OR, 3.54; 95% CI, 2.02-6.20; P < .001; engagement, 15.5% vs 4.2%; adjusted OR, 5.89; 95% CI, 2.43-14.32; P < .001) as was abstinence from opioids, cocaine, methamphetamines, marijuana, and any alcohol (26.3% vs 15.6%; effect estimate, β = 0.13; 95% CI, 0.03-0.23; P = .01).

CONCLUSIONS AND RELEVANCE:
Among adults with OAUD in primary care, the SUMMIT collaborative care intervention resulted in significantly more access to treatment and abstinence from alcohol and drugs at 6 months, than usual care.

Disparities in the Quality of Cardiovascular Care Between HIV‐Infected Versus HIV‐Uninfected Adults in the United States: A Cross‐Sectional Study. Journal of the American Heart Association. 2017 Nov 1;6(11). PMCID: PMC5721786

Abstract/Summary:
BACKGROUND:
Cardiovascular disease is emerging as a major cause of morbidity and mortality among patients with HIV. We compared use of national guideline-recommended cardiovascular care during office visits among HIV-infected versus HIV-uninfected adults.

METHODS AND RESULTS:
We analyzed data from a nationally representative sample of HIV-infected and HIV-uninfected patients aged 40 to 79 years in the National Ambulatory Medical Care Survey/National Hospital Ambulatory Medical Care Survey, 2006 to 2013. The outcome was provision of guideline-recommended cardiovascular care. Logistic regressions with propensity score weighting adjusted for clinical and demographic factors. We identified 1631 visits by HIV-infected patients and 226 862 visits by HIV-uninfected patients with cardiovascular risk factors, representing ≈2.2 million and 602 million visits per year in the United States, respectively. The proportion of visits by HIV-infected versus HIV-uninfected adults with aspirin/antiplatelet therapy when patients met guideline-recommended criteria for primary prevention or had cardiovascular disease was 5.1% versus 13.8% (P=0.03); the proportion of visits with statin therapy when patients had diabetes mellitus, cardiovascular disease, or dyslipidemia was 23.6% versus 35.8% (P<0.01). There were no differences in antihypertensive medication therapy (53.4% versus 58.6%), diet/exercise counseling (14.9% versus 16.9%), or smoking cessation advice/pharmacotherapy (18.8% versus 22.4%) between HIV-infected versus HIV-uninfected patients, respectively.

CONCLUSIONS:
Physicians generally underused guideline-recommended cardiovascular care and were less likely to prescribe aspirin and statins to HIV-infected patients at increased risk-findings that may partially explain higher rates of adverse cardiovascular events among patients with HIV. US policymakers and professional societies should focus on improving the quality of cardiovascular care that HIV-infected patients receive.

Abstract
Self-rated health (SRH) is associated with morbidity and mortality in HIV-uninfected populations but is understudied in HIV. Substance use may affect SRH in addition to its deleterious effect on HIV disease. This analysis aimed to estimate SRH and substance use prevalence and evaluate factors associated with poor SRH among individuals in HIV care in Rio de Janeiro, Brazil. A convenience sample of HIV-infected adults completed one item of SRH, the Alcohol, Smoking and Substance Involvement Screening Test, and the Patient Health Questionnaire-2 (PHQ-2). Logistic regression models identified factors associated with poor SRH. Participants’ (n = 1029) median age was 42.9 years, 64.2% were male, and 54.5% were nonwhite. Poor SRH was reported by 19.5% and the use of alcohol, tobacco, marijuana, and crack/cocaine by 30.1, 19.5, 3.9, and 3.5%, respectively. Less than high school education (adjusted odds ratio [aOR] 1.54, 95% confidence interval [CI]: 1.08-2.20), lack of sexual activity in previous 12 months (aOR 1.53, 95% CI: 1.01-2.30), crack/cocaine use (aOR 3.82, 95% CI: 1.80-8.09), positive PHQ-2 screen (aOR 3.43, 95% CI: 2.09-5.62), and HIV-1 RNA ≥40 c/ml (aOR 2.51, 95% CI: 1.57-4.02) were significantly associated with poor SRH as identified by logistic regression analyses. Alcohol, marijuana, and sedative use were not significantly associated with poor SRH. These results emphasize the need for substance use and mental health screening and treatment in this population. Further research may elucidate the consequences of poor SRH on treatment adherence, morbidity, and mortality in HIV-infected individuals.

Abstract
Condomless anal intercourse among transgender women (TW) in Peru has been shown to vary by the type of partner involved (e.g. primary vs. casual vs. transactional sex partner), but no previous studies have explored variations in partner-level patterns of condom use according to type of anal intercourse. We evaluated the relationship between partnership characteristics and condom use during insertive (IAI) versus receptive anal intercourse (RAI) among TW with recent, non-female partners. Condomless IAI was more common with transactional and casual sex partners and by TW who self-reported HIV-uninfected serostatus (p < 0.05), alcohol use disorders, or substance use before sex. Condomless RAI was more common with primary partners and by TW who described their HIV serostatus as unknown (p < 0.05). Examining partner-level differences between condomless IAI and RAI reveals distinct patterns of HIV/STI risk among TW, suggesting a need for HIV prevention strategies tailored to the specific contexts of partners, practices, and networks.

Assessing and improving organizational readiness to implement substance use disorder treatment in primary care: findings from the SUMMIT study. BMC family practice. 2017 Dec;18(1):107. PMCID: PMC5740845.

Abstract
BACKGROUND:
Millions of people with substance use disorders (SUDs) need, but do not receive, treatment. Delivering SUD treatment in primary care settings could increase access to treatment because most people visit their primary care doctors at least once a year, but evidence-based SUD treatments are underutilized in primary care settings. We used an organizational readiness intervention comprised of a cluster of implementation strategies to prepare a federally qualified health center to deliver SUD screening and evidence-based treatments (extended-release injectable naltrexone (XR-NTX) for alcohol use disorders, buprenorphine/naloxone (BUP/NX) for opioid use disorders and a brief motivational interviewing/cognitive behavioral -based psychotherapy for both disorders). This article reports the effects of the intervention on key implementation outcomes.

METHODS:
To assess changes in organizational readiness we conducted pre- and post-intervention surveys with prescribing medical providers, behavioral health providers and general clinic staff (N = 69). We report on changes in implementation outcomes: acceptability, perceptions of appropriateness and feasibility, and intention to adopt the evidence-based treatments. We used Wilcoxon signed rank tests to analyze pre- to post-intervention changes.

RESULTS:
After 18 months, prescribing medical providers agreed more that XR-NTX was easier to use for patients with alcohol use disorders than before the intervention, but their opinions about the effectiveness and ease of use of BUP/NX for patients with opioid use disorders did not improve. Prescribing medical providers also felt more strongly after the intervention that XR-NTX for alcohol use disorders was compatible with current practices. Opinions of general clinic staff about the appropriateness of SUD treatment in primary care improved significantly.

CONCLUSIONS:
Consistent with implementation theory, we found that an organizational readiness implementation intervention enhanced perceptions in some domains of practice acceptability and appropriateness. Further research will assess whether these factors, which focus on individual staff readiness, change over time and ultimately predict adoption of SUD treatments in primary care.

Abstract
In Peru, the HIV epidemic is concentrated in men who have sex with men (MSM) and transgender women (TGW). Multiple studies correlate alcohol use disorders (AUDs) with risky sexual behaviors among Peruvian MSM. Qualitative research was used to inform a clinical trial on the acceptability of medication-assisted therapies to assist management of AUDs and improve antiretroviral therapy (ART) adherence among MSM/TGW in Peru. Three focus groups involving HIV-infected or HIV-uninfected MSM/TGW ( n = 26) with AUDs (AUDIT ≥ 8) were transcribed, translated from Spanish into English, and analyzed using thematic content analysis. Despite having an AUD, participants considered themselves “social” drinkers, minimized their drinking behaviors, and differed about whether or not alcohol problems could be treated. Participants expressed skepticism about medication for treating AUDs. Three concepts emerged as necessary components of a treatment program for alcohol problems: cost, family support, and the potential to drink less alcohol without attaining total abstinence. This study reveals important areas of education to increase potential acceptability of a medication for treating AUDs among MSM/TGW. Given the social conditions and knowledge base of the participants, medication-assisted therapies using naltrexone may be a beneficial strategy for MSM with AUDs.

Abstract
BACKGROUND:
The plenary session at the 2016 Behavior, Biology and Chemistry: Translational Research in Addiction Conference focused on glia as potential players in the development, persistence and treatment of substance use disorders. Glia partake in various functions that are important for healthy brain activity. Drugs of abuse alter glial cell activity producing several perturbations in brain function that are thought to contribute to behavioral changes associated with substance use disorders. Consequently, drug-induced changes in glia-driven processes in the brain represent potential targets for pharmacotherapeutics treating substance use disorders.

METHODS:
Four speakers presented preclinical and clinical research illustrating the effects that glial modulators have on abuse-related behavioral effects of psychostimulants and opioids. This review highlights some of these findings and expands its focus to include other research focused on drug-induced glia abnormalities and glia-focused treatment approaches in substance use disorders.

RESULTS:
Preclinical findings show that drugs of abuse induce neuroinflammatory signals and disrupt glutamate homeostasis through their interaction with microglia and astrocytes. Preclinical and clinical studies testing the effects of glial modulators show general effectiveness in reducing behaviors associated with substance use disorders.

CONCLUSIONS:
The contribution of drug-induced glial activity continues to emerge as an intriguing target for substance use disorder treatments. Clinical investigations of glial modulators have yielded promising results on substance use measures and indicate that they are generally safe and well-tolerated. However, results have not been entirely positive and more questions remain for continued exploration in the development and testing of glial-directed treatments for substance use disorders.

Abstract
BACKGROUND:
Multistage, stepwise HIV testing and treatment procedures can result in lost opportunities to provide timely antiretroviral therapy (ART). Incomplete engagement of patients along the care cascade translates into high preventable mortality. We aimed to identify whether a structural intervention to streamline testing and linkage to HIV health care would improve testing completeness, ART initiation, and viral suppression and reduce mortality.

METHODS:
We did a cluster-randomised, controlled trial in 12 hospitals in Guangxi, China. All hospitals were required to be level 2A county general hospitals and ART delivery sites. We selected the 12 most similar hospitals in terms of structural characteristics, past patient caseloads, and testing procedures. Hospitals were randomly assigned (1:1) to either the One4All intervention or standard of care. Hospitals were randomised in a block design and stratified by the historical rate of testing completeness of the individual hospital during the first 6 months of 2013. We enrolled patients aged 18 years or older who were identified as HIV-reactive during screening in study hospitals, who sought inpatient or outpatient care in a study hospital, and who resided in the study catchment area. The One4All strategy incorporated rapid, point-of-care HIV screening and CD4 counts, and in-parallel viral load testing, to promote fast and complete diagnosis and staging and provide immediate ART to eligible patients. Participants in control hospitals received standard care services. All enrolled patients were assessed for the primary outcome, which was testing completeness within 30 days, defined as completion of three required tests and their post-test counselling. Safety assessments were hospital admissions for the first 90 days and deaths up to 12 months after enrolment. This trial is registered with ClinicalTrials.gov, number NCT02084316.

FINDINGS:
Between Feb 24 and Nov 25, 2014, we enrolled 478 patients (232 in One4All, 246 in standard of care). In the One4All group, 177 (76%) of 232 achieved testing completeness within 30 days versus 63 (26%) of 246 in the standard-of-care group (odds ratio 19·94, 95% CI 3·86-103·04, p=0·0004). Although no difference was observed between study groups in the number of hospital admissions at 90 days, by 12 months there were 65 deaths (28%) in the in the One4All group compared with 115 (47%) in the standard-of-care group (Cox proportional hazard ratio 0·44, 0·19-1·01, p=0·0531).

INTERPRETATION:
Our study provides strong evidence for the benefits of a patient-centred approach to streamlined HIV testing and treatment that could help China change the trajectory of its HIV epidemic, and help to achieve the goal of an end to AIDS.

FUNDING:
US National Institute on Drug Abuse Clinical Trials Network and China’s National Health and Family Planning Commission.

Sowing the seeds of transformative practice to actualize women’s rights to respectful maternity care: reflections from Kenya using the consolidated framework for implementation research. BMC women’s health. 2017 Dec;17(1):69.

Abstract
BACKGROUND:
Despite years of growing concern about poor provider attitudes and women experiencing mistreatment during facility based childbirth, there are limited interventions that specifically focus on addressing these issues. The Heshima project is an evidence-based participatory implementation research study conducted in 13 facilities in Kenya. It engaged a range of community, facility, and policy stakeholders to address the causes of mistreatment during childbirth and promote respectful maternity care.

METHODS:
We used the consolidated framework for implementation research (CFIR) as an analytical lens to describe a complex, multifaceted set of interventions through a reflexive and iterative process for triangulating qualitative data. Data from a broad range of project documents, reports, and interviews were collected at different time points during the implementation of Heshima. Assessment of in-depth interview data used NVivo (Version 10) and Atlas.ti software to inductively derive codes for themes at baseline, supplemental, and endline. Our purpose was to generate categories of themes for analysis found across the intervention design and implementation stages.

RESULTS:
The implementation process, intervention characteristics, individual champions, and inner and outer settings influenced both Heshima’s successes and challenges at policy, facility, and community levels. Implementation success stemmed from readiness for change at multiple levels, constant communication between stakeholders, and perceived importance to communities. The relative advantage and adequacy of implementation of the Respectful Maternity Care (RMC) resource package was meaningful within Kenyan politics and health policy, given the timing and national promise to improve the quality of maternity care.

CONCLUSION:
We found the CFIR lens a promising and flexible one for understanding the complex interventions. Despite the relatively nascent stage of RMC implementation research, we feel this study is an important start to understanding a range of interventions that can begin to address issues of mistreatment in maternity care; replication of these activities is needed globally to better understand if the Heshima implementation process can be successful in different countries and regions.

Complementary and Alternative Medicine Use for HIV Management in the State of Florida: Medical Monitoring Project. The Journal of Alternative and Complementary Medicine, 22(11), pp.880-886. PMCID: PMC5116687

Abstract

OBJECTIVE:
The aims of this study were to describe complementary and alternative medicine (CAM) use and to assess the relationships between CAM use and antiretroviral therapy (ART) adherence and human immunodeficiency virus (HIV) RNA viral load suppression among a sample of persons living with HIV (PLWH) engaged in care in the state of Florida.

DESIGN:
The Florida Medical Monitoring Project (n = 803) collected repeated cross-sectional data for surveillance of clinical outcomes among PLWH from 2009 to 2010. Past-year CAM use specifically for the management of HIV was measured via self-report. Logistic regression models were conducted to assess the effect of CAM use on ART adherence and viral load suppression, controlling for demographic and clinical factors using backwards stepwise deletion of factors with a p-value of >0.25.

RESULTS:
CAM use was reported in 53.3% (n = 428). In bivariate analysis, CAM use was the highest among those 40-49 years of age (61%; p < 0.05), males (56%; p < 0.01), whites (61%; p = 0.001), and those educated beyond high school (59%; p < 0.05). Among those using CAM, 63% and 37% reported one and two or more CAM modalities, respectively. CAM modalities included biologically based therapies (89%), mind-body medicine/manipulative body-based therapies (30%), spiritual healing (23%), energy therapies (6%), and whole medical systems (6%). In multivariable analyses, any CAM use and number of CAM methods used were not associated with ART adherence. Any CAM use was not associated with detectable viral load (adjusted odds ratio [aOR] 0.81; 95% confidence interval [CI] 0.58-1.12; p = 0.20). Those using two or more methods had significantly decreased risk for detectable viral load (aOR 0.60; 95% CI 0.39-0.92; p < 0.02).

CONCLUSIONS:
CAM use was not associated with negative effects on ART adherence. CAM users were less likely to have detectable viral load compared with non-users. Future research should focus on CAM use among PLWH not engaged in HIV care and the longitudinal patterns of CAM use and possible effects of long-term health outcomes.

Abstract

BACKGROUND:
Marijuana use is common among persons living with HIV (PLWH), but studies on its effect on HIV clinical outcomes are limited.

OBJECTIVES:
We determined the association between marijuana use and HIV viral suppression among PLWH.

METHODS:
Data came from five repeated cross-sections (2009-2013) of the Florida Medical Monitoring Project, a population-based sample of PLWH in Florida. Data were obtained via interview and medical record abstraction (MRA). Weighted logistic regression models were used to determine the association between marijuana use (past 12 months) and durable viral suppression (HIV-1 RNA value of ≤ 200 copies/milliliter in all measurements within the past 12 months).

RESULTS:
Of the 1,902 PLWH receiving antiretroviral therapy, completed an interview, and had a linked MRA, 20% reported marijuana use (13% less than daily and 7% daily use) and 73% achieved durable viral suppression. In multivariable analysis, marijuana use was not significantly associated with durable viral suppression in daily [Adjusted Odds Ratio (AOR): 0.87, 95% confidence interval (CI): 0.58, 1.33] or in less than daily [AOR: 0.83, 95% CI: 0.51, 1.37] users as compared to non-users when adjusting for sociodemographic factors, time since HIV diagnosis, depressive symptoms, alcohol, cigarette and other substance use.

CONCLUSION:
In this sample of PLWH receiving medical care in Florida, there was no statistically significant association between marijuana use and viral suppression. However, as the limits of the confidence intervals include effects that may be considered to be clinically important, there is a need for additional evidence from other samples and settings that include more marijuana users.

Body mass index, inflammatory biomarkers and neurocognitive impairment in HIV-infected persons. Psychology, health & medicine, 22(3), pp.289-302. PMCID: PMC5173436

Abstract
To determine the relationships among body mass index (BMI), and HIV-associated neurocognitive impairment and the potential mediating effects of inflammatory cytokines. Among the HIV-infected individuals (N = 90) included in this study, obesity was associated with slower processing speed (β = -.229, standard error (SE) = 2.15, p = .033), compared to participants with a normal BMI, after controlling for psychosocial and HIV clinical factors. Serum concentrations of the interleukin-16 (IL-16) cytokine were significantly associated with slowed processing speed (β = -.235, SE = 1.62, p = .033) but did not mediate the relationship between obesity and processing speed These findings suggest that obesity may contribute to cognitive processing speed deficits in HIV-infected adults. Elevated concentrations of IL-16 are also associated with slowing, though the results suggest that obesity and IL-16 may exert independent effects.

Association of midlife smoking status with change in processing speed and mental flexibility among HIV-seropositive and HIV-seronegative older men: the Multicenter AIDS Cohort Study. Journal of neurovirology, 23(2), pp.239-249. PMCID: PMC5663220

Abstract
Smoking is a potential risk factor for age-related cognitive decline. To date, no study has examined the association between smoking and cognitive decline in men living with human immunodeficiency virus (HIV). The aim of this present study is to examine whether smoking status and severity in midlife is associated with a rate of decline in cognitive processing speed among older HIV-seropositive and HIV-seronegative men who have sex with men. Data from 591 older HIV-seropositive and HIV-seronegative men who have sex with men from the Multicenter AIDS Cohort Study were examined. All participants had information on smoking history collected before age 50 years and at least 5 years of follow-up after age 50. Smoking history was categorized as never smoker, former smoker, and current smoker and cumulative pack years was calculated.
