Violence Victimization, Homelessness, and Severe Mental Illness Among People Who Use Opioids in Three U.S. Cities.

This study examined the associations between violence victimization, homelessness, and severe mental illness (SMI) among people who use opioids (PWUOs) in three U.S. cities. We analyzed data from a cross-sectional survey conducted from May 2019 to February 2020 across three study sites: Los Angeles, CA; Las Vegas, NV; and Atlanta, GA. We used multivariable regressions to examine how multiple victimizations and housing situation are associated with SMI. Based on K-6 scale, nearly half (44.2%) were screened positive for SMI. Meanwhile, 69.7% of the participants reported experiencing some kind of violence in their lifetime, and more than half (51.9%) reported experiencing recent violence (in the past 6 months). The most common form of lifetime violence was emotional (59.5%), followed by physical and intimate partner violence (IPV) (56.1 and 34.9%, respectively), and 34.9% of all participants reported experiencing multiple forms of victimization in the past 6 months. Participants who reported homelessness were more likely to report having experienced recent violence victimization (p < .001). In multivariable models, experiencing recent victimization was significantly associated with SMI (adjusted odds ratio (AOR) = 1.85, 95% confidence interval [CI] [1.46, 2.38]), as was homelessness (AOR = 1.57, 95% CI [1.15, 2.14]), after adjusting for study covariates. Among those with moderate and SMI (n = 927), only 22% were currently receiving mental health services, and those who reported having experienced any forms of violence in the past 6 months were more likely to utilize mental health services than those who had not experienced any recent violence victimization (25 vs. 17.9%, p < .05). To improve mental health and wellness among this high priority population, mental health facilities and syringe service programs may consider screening for experiences of violence and using trauma-informed mental health approaches. Harm reduction interventions must be responsive to the diverse individual and structural-level needs of PWUOs, especially those experiencing homelessness and housing insecurity. Holistic strategies and services are needed to meet the social and structural needs of this population.

Prevalence of Nicotine and Tobacco Product Use by Sexual Identity, Gender Identity, and Sex Assigned at Birth Among Emerging Adult Tobacco Users in California, United States.

INTRODUCTION: Sexual and gender minority (SGM) nicotine and tobacco use disparities are well-documented among youth and young adults (YYA), and despite decades of prevention efforts, these disparities stubbornly persist. To better understand tobacco use disparities and craft tailored interventions, tobacco use patterns must be assessed in a contemporary sample of YYA across lines of sexual and gender identity, sex assigned at birth, and tobacco product types. AIMS AND METHODS: Data were from an online survey of a diverse sample of emerging adult tobacco users (ages 18-29; N = 1491) in California, United States (2020-2021). Participants were recruited from various online and in-person locations. Bivariate and adjusted models assessed differences in four nicotine and tobacco use outcomes (past 30-day use of cigarettes, e-cigarettes, other tobacco products, and multiple tobacco product types) across six groups: Cisgender heterosexual males, cisgender heterosexual females, cisgender sexual minority (SM) males, cisgender SM females, transfeminine participants, and transmasculine participants. RESULTS: Compared to cisgender heterosexual males, both transfeminine (OR = 2.25, 95% confidence intervals (CI) = 1.29 to 4.05) and transmasculine (OR = 1.85, 95% CI = 1.32 to 2.80) participants had higher odds of using cigarettes. Few differences were noted between groups in use of e-cigarettes. Cisgender heterosexual males had higher odds of other tobacco product use, compared to most other groups (eg, cisgender SM males: OR = 0.57, 95% CI = 0.37 to 0.87). Transmasculine participants had higher odds of multiple product use, compared to cisgender heterosexual females. Among multiple product users, transfeminine participants had the highest prevalence of using all three individual product types (35.6%). CONCLUSIONS: Results highlight the need for different tobacco control approaches across sexual and gender identities, sex assigned at birth, and nicotine and tobacco products. IMPLICATIONS: SGM nicotine and tobacco use disparities remain entrenched, despite concerted efforts to reduce them. The SGM population is heterogeneous and different SGM subgroups may have different needs. This study assessed, among young adult nicotine and tobacco users in California, U.S. patterns of tobacco use across sexual and gender identities, sex assigned at birth, as well as specific tobacco products used-a necessity to craft tailored tobacco control measures. We found patterns of nicotine and tobacco product use across several of these characteristics, highlighting how different prevention and cessation interventions may be needed to meaningfully address SGM nicotine and tobacco use disparities.

The associations between HIV stigma and mental health symptoms, life satisfaction, and quality of life among Black sexual minority men with HIV.

PURPOSE: With the advancement of antiretroviral therapy (ART), HIV/AIDS has become a manageable illness, similar to other chronic conditions. This study examined the associations between HIV stigma and patient-reported outcomes including mental health symptoms, life satisfaction, and quality of life among Black sexual minority men with HIV. METHODS: We analyzed baseline data from a randomized comparison trial of a mobile app intervention aimed to address the social work and legal needs of Black sexual minority men with HIV in Los Angeles County. We used validated scales including the Berger HIV stigma scale, the Patient Health Questionnaire-9 & the General Anxiety Disorder-7, the Satisfaction with Life Scale, and the Ladder Scale to assess HIV stigma, depressive symptoms, anxiety, life satisfaction, and quality of life, and we conducted multivariable linear regression to examine their associations. RESULTS: Participants experienced HIV stigma especially about disclosure concerns (e.g., 81.9% participants indicated "I am very careful who I tell that I have HIV") and public attitudes (52.3% believed "Most people with HIV are rejected when others find out"). In the multivariable models, higher overall stigma scores were associated with higher likelihood of experiencing depression (adjusted b = 0.235, p < 0.001) and anxiety (adjusted b = 0.188, p = 0.002), and lower life satisfaction (adjusted b = - 0.236, p < 0.001) and quality of life (adjusted b = - 0.053, p = 0.013), adjusting for clinical characteristics including ART initiation, viral load suppression, and medication adherence. In addition, being attacked or harassed in the past year were significantly associated with lower life satisfaction and quality of life (adjusted b = - 3.028, p = 0.046; adjusted b = - 1.438, p = 0.002). CONCLUSION: Our findings highlight the need for focused HIV stigma reduction interventions to promote the overall well-being of Black sexual minority men with HIV. Strategies to promote the patient-reported outcomes may benefit from trauma-informed approaches.

Leveraging Social Media Activity and Machine Learning for HIV and Substance Abuse Risk Assessment: Development and Validation Study.

BACKGROUND: Social media networks provide an abundance of diverse information that can be leveraged for data-driven applications across various social and physical sciences. One opportunity to utilize such data exists in the public health domain, where data collection is often constrained by organizational funding and limited user adoption. Furthermore, the efficacy of health interventions is often based on self-reported data, which are not always reliable. Health-promotion strategies for communities facing multiple vulnerabilities, such as men who have sex with men, can benefit from an automated system that not only determines health behavior risk but also suggests appropriate intervention targets. OBJECTIVE: This study aims to determine the value of leveraging social media messages to identify health risk behavior for men who have sex with men. METHODS: The Gay Social Networking Analysis Program was created as a preliminary framework for intelligent web-based health-promotion intervention. The program consisted of a data collection system that automatically gathered social media data, health questionnaires, and clinical results for sexually transmitted diseases and drug tests across 51 participants over 3 months. Machine learning techniques were utilized to assess the relationship between social media messages and participants' offline sexual health and substance use biological outcomes. The F1 score, a weighted average of precision and recall, was used to evaluate each algorithm. Natural language processing techniques were employed to create health behavior risk scores from participant messages. RESULTS: Offline HIV, amphetamine, and methamphetamine use were correctly identified using only social media data, with machine learning models obtaining F1 scores of 82.6%, 85.9%, and 85.3%, respectively. Additionally, constructed risk scores were found to be reasonably comparable to risk scores adapted from the Center for Disease Control. CONCLUSIONS: To our knowledge, our study is the first empirical evaluation of a social media-based public health intervention framework for men who have sex with men. We found that social media data were correlated with offline sexual health and substance use, verified through biological testing. The proof of concept and initial results validate that public health interventions can indeed use social media-based systems to successfully determine offline health risk behaviors. The findings demonstrate the promise of deploying a social media-based just-in-time adaptive intervention to target substance use and HIV risk behavior.

Perspectives on academic mentorship from sexual and gender minority students pursuing careers in the health sciences.

High-quality academic mentorship is key to the success of students pursuing careers in the health sciences. Mentorship may take on additional importance for sexual and gender minority (SGM) students, who often face stressors related to stigmatized identities. We conducted an anonymous online survey to assess the mentorship experiences of SGM students pursuing careers in the health sciences and to elicit their perspectives on what makes an effective mentor. Students (N = 166) were pursuing a variety of health-related careers, including medicine (12.7%), nursing (7.8%), public health (21.1%), and social work (19.3%). Overall, students rated the quality of their mentorship experiences as (very) good: 83.8% among participants who reported having had an academic mentor that openly identified as SGM and 79.5% among participants who had a non-SGM identified mentor (ns). Participants recommended individual, dyadic and structural level activities that could be undertaken by academic mentors of SGM students to promote the students' academic success and positive career trajectories. Education on SGM issues, direct conversation about experiences of homophobia and transphobia in academic settings, and advocacy for including SGM content in coursework were among the suggestions provided by participants.

Quadrivalent Meningococcal Vaccine Uptake Among Men Who Have Sex With Men During a Meningococcal Outbreak in Los Angeles County, California, 2016-2017.

OBJECTIVE: The objective of our study was to assess meningococcal ACWY (MenACWY) vaccine uptake among men who have sex with men (MSM) during an ongoing, invasive meningococcal disease outbreak in Southern California. This research was important to inform future vaccination uptake interventions for this high-priority population. METHODS: We conducted venue-based sampling to recruit and enroll MSM living in Los Angeles County, California, from December 2016 through February 2017. We conducted bivariate and multivariable analyses to evaluate associations between MenACWY vaccine uptake and other predetermined factors. RESULTS: Of 368 participants, 138 (37.5%) reported receiving the MenACWY vaccine. In multivariable analyses, older age (adjusted odds ratio [aOR] = 2.57; 95% confidence interval [CI], 1.31-5.03), previous diagnosis of a sexually transmitted infection (aOR = 2.22; 95% CI, 1.14-4.30), belief that MenACWY vaccine is important (aOR = 3.49; 95% CI, 1.79-6.82), confidence in the MenACWY vaccine (aOR = 5.53; 95% CI, 3.11-9.83), and knowing someone who had been vaccinated (aOR = 5.82; 95% CI, 3.05-11.12) were significantly associated with MenACWY vaccine uptake. CONCLUSIONS: Our findings reflect low uptake of the recommended MenACWY vaccine among MSM after a local outbreak, despite public health efforts. In addition to ongoing, widespread campaigns to inform MSM about local outbreaks and vaccination recommendations, MSM may be responsive to direct outreach from peers who have been vaccinated.

Compound W, a 3,3'-diiodothyronine sulfate cross-reactive substance in serum from pregnant women--a potential marker for fetal thyroid function.

Compound W, a 3,3'-diiodothyronine sulfate (T2S) cross-reactive material in maternal serum, was found to be useful as a marker for fetal hypothyroidism. In the present report, we explored its biochemical properties and studied its concentrations in cord and in maternal serum obtained from various gestational periods and at term from different continents. Mean W concentrations, expressed as nmol/L T2S-equivalent, in maternal serum during gestation showed a moderate increase at 20-26 wk (1.57 nmol/L) and an accelerated increase to 34-40 wk (3.59 nmol/L). The mean serum level was relatively low in nonpregnant women (0.17 nmol/L). Compound W levels in cord and maternal serum at term were not significantly different among samples obtained from Taiwan compared with samples from the United States. The mean cord serum "corrected" (by hot acid digestion) concentrations of W were significantly higher than maternal serum concentrations at birth and were also higher in venous than in paired arterial samples, suggesting that the placenta may play a role in its production. We compared a total of 45 iodothyronine analogs by antibody, gel filtration, and HPLC chromatographic studies and found only one compound, N,N-dimethyl-T2S, that has close similarities to Compound W. Further studies are needed.
