Acceptance of digital phenotyping linked to a digital pill system to measure PrEP adherence among men who have sex with men with substance use.

Once-daily oral HIV pre-exposure prophylaxis (PrEP) is an effective strategy to prevent HIV, but is highly dependent on adherence. Men who have sex with men (MSM) who use substances face unique challenges maintaining PrEP adherence. Digital pill systems (DPS) allow for real-time adherence measurement through ingestible sensors. Integration of DPS technology with other digital health tools, such as digital phenotyping, may improve understanding of nonadherence triggers and development of personalized adherence interventions based on ingestion behavior. This study explored the willingness of MSM with substance use to share digital phenotypic data and interact with ancillary systems in the context of DPS-measured PrEP adherence. Adult MSM on PrEP with substance use were recruited through a social networking app. Participants were introduced to DPS technology and completed an assessment to measure willingness to participate in DPS-based PrEP adherence research, contribute digital phenotyping data, and interact with ancillary systems in the context of DPS-based research. Medical mistrust, daily worry about PrEP adherence, and substance use were also assessed. Participants who identified as cisgender male and were willing to participate in DPS-based research (N = 131) were included in this subsample analysis. Most were White (76.3%) and non-Hispanic (77.9%). Participants who reported daily PrEP adherence worry had 3.7 times greater odds (95% CI: 1.03, 13.4) of willingness to share biometric data via a wearable device paired to the DPS. Participants with daily PrEP adherence worry were more likely to be willing to share smartphone data (p = 0.006) and receive text messages surrounding their daily activities (p = 0.003), compared to those with less worry. MSM with substance use disorder, who worried about PrEP adherence, were willing to use DPS technology and share data required for digital phenotyping in the context of PrEP adherence measurement. Efforts to address medical mistrust can increase advantages of this technology for HIV prevention.

Informing Acceptability and Feasibility of Digital Phenotyping for Personalized HIV Prevention among Marginalized Populations Presenting to the Emergency Department.

For marginalized populations with ongoing HIV epidemics, alternative methods are needed for understanding the complexities of HIV risk and delivering prevention interventions. Due to lack of engagement in ambulatory care, such groups have high utilization of drop-in care. Therefore, emergency departments represent a location with those at highest risk for HIV and in highest need of novel prevention methods. Digital phenotyping via data collected from smartphones and other wearable sensors could provide the innovative vehicle for examining complex HIV risk and assist in delivering personalized prevention interventions. However, there is paucity in exploring if such methods are an option. This study aimed to fill this gap via a cross-sectional psychosocial assessment with a sample of N=85 emergency department patients with HIV risk. Findings demonstrate that although potentially feasible, acceptability of digital phenotyping is questionable. Technology-assisted HIV prevention needs to be designed with the target community and address key ethical considerations.

Pathways and Intersections: Multifaceted Approaches to Engage Individuals From Underrepresented and Marginalized Communities in HIV Research and Career Development.

BACKGROUND: The underrepresentation of historically marginalized groups in the HIV research workforce is a barrier to reaching national Ending the Epidemic goals. SETTING: The Harvard University Center for AIDS Research (HU CFAR) Diversity Equity and Inclusion Working Group (DEI WG) uses a multifaceted approach to enhance the field's diversity. METHODS: We established a DEI WG to improve the recruitment, inclusion, and retention of underrepresented minorities (URMs) in HIV research. We use community-based, participatory processes to establish and expand education and outreach programs about HIV care and research to better connect the HU CFAR to communities affected by HIV. This article reports on the development of the WG in July 2022, progress in its first year, and future plans. RESULTS: We have built a network of >50 investigators across the university for monthly meetings; partnered with existing research pathway programs for high school, undergraduate, and graduate students, directly supporting 7 new trainees and linking CFAR investigators to additional mentorship opportunities; and created 2-year Scholar Awards for 5 URM investigators in HIV. Planned work includes needs assessments for early-stage investigators to understand factors contributing to inclusion and retention and new pathway and outreach programming being developed with community partner minority-serving institutions. CONCLUSIONS: The HU CFAR DEI WG strives to ensure that individuals from underrepresented, marginalized, and minoritized communities have an opportunity to contribute to HIV research and that research is informed by the needs of the communities affected by the epidemic. An intersectional approach should be incorporated into HIV research pathway initiatives.

Attitudes towards participating in research involving digital pill systems to measure oral HIV pre-exposure chemoprophylaxis: a cross-sectional study among men who have sex with men with substance use in the USA.

OBJECTIVES: This quantitative survey sought to understand, among men who have sex with men (MSM) with potentially problematic substance use, the attitudes towards participation in research involving digital pill systems (DPS) for HIV pre-exposure prophylaxis (PrEP) adherence measurement, and the barriers and facilitators to research participation. DESIGN: One-time, cross-sectional, online sampling-based survey. SETTING: US social networking app predominantly focused on MSM. PARTICIPANTS: MSM without HIV who reported current use of oral PrEP, potentially problematic substance use and sexual activity in the past 3 months. A total of 157 participants were eligible, passed validity checks and enrolled. OUTCOME MEASURES: Perceptions of DPS usefulness, accuracy and usability (System Usability Scale (SUS)); willingness and motivations to participate in DPS research; preferences for access to and feedback on DPS adherence data; data sharing considerations; and medical mistrust (Group-Based Medical Mistrust Scale (GBMMS)). RESULTS: Most of the sample (N=157) was white (n=119, 75.8%), gay (n=124, 79.0%) and cisgender (n=150, 95.5%). The median age was 33 years (IQR: 14). The mean GBMMS score was 13.5 (SD=5.2), and the median SUS score was 70 (IQR: 27.5). In the past 3 months, 36.3% (n=57) reported frequent use of substances before or during sex, and 62.4% (n=98) engaged in condomless sex. While most were adherent to PrEP, approximately 34.4% (n=54) expressed significant worry about daily adherence. Participants wished to monitor their PrEP adherence daily (n=66, 42.0%) and 52% (n=82) were very willing to participate in DPS-based research. The majority were minimally concerned about sharing DPS-detected adherence data with research teams (n=126, 80.3%), and were extremely willing to share these data with healthcare providers (n=109, 69.4%). CONCLUSIONS: In this sample, MSM without HIV who use substances reported willingness to use DPS to measure PrEP adherence in a research context, and identified benefits to accessing real-time, DPS-detected adherence data.

Does Problematic Substance Use Moderate Efficacy of Cognitive Behavioral Therapy for Adherence and Depression in HIV?

Problematic substance use may attenuate the effect of treating depression in people living with HIV (PLWH). We examined the potential moderating effect of problematic substance use on depression and adherence outcomes in PLWH (N = 143) who participated in a randomized controlled trial of cognitive behavioral therapy for adherence and depression (CBT-AD) and were randomized to either CBT-AD or enhanced treatment as usual (ETAU). Problematic substance use was operationalized as either having substance use-related diagnosis or current substance use in the past 30 days with a lifetime history of problematic use. Acute (baseline to 4-month) and follow up (4, 8, and 12-month) general linear modeling with time, condition, problematic baseline substance use, and corresponding interactions demonstrated that substance use did not significantly moderate the effects of CBT-AD on adherence or depression improvements. Therefore, CBT-AD was beneficial for PLWH with depression, regardless of problematic substance use when starting depression treatment. Based on these results, clinicians should not withhold CBT treatment for depression in patients with HIV and problematic substance use to attain reductions in depression and gains in adherence.

Posttraumatic Cognitions and Condomless Sex Among Men Who Have Sex with Men (MSM) with a History of Childhood Sexual Abuse: The Role of Avoidance Coping.

This study explicated associations between trauma-related cognitions and condomless sex, examining avoidance coping style and behavior (i.e., substance use) as intermediate variables, among a group disproportionately affected by both trauma and HIV. Two hundred and ninety HIV-negative MSM with a history of childhood sexual abuse (CSA) completed a cross-sectional psychosocial battery. Trauma-related cognitions were positively associated with more acts of condomless sex. Indirect associations on condomless sex were driven by avoidance coping, but not substance use. Findings indicate a need to address trauma-related cognitions and avoidance coping within interventions for reducing HIV risk among MSM with a history of CSA.

Sexual Minority Stress and Cellular Aging in Methamphetamine-Using Sexual Minority Men With Treated HIV.

OBJECTIVE: Sexual minority men (e.g., gay, bisexual, and other men who have sex with men) experience stigma and sexual minority stress, which are theorized to drive negative health outcomes. Sexual minority men with treated HIV display persistent immune dysregulation, which could be amplified by sexual minority stress responses to potentiate cellular aging. METHODS: This cross-sectional study included 52 sexual minority men living with HIV who had undetectable viral load (<40 copies/mL) and biologically confirmed recent methamphetamine use. Participants completed measures assessing sexual minority stress and openness about sexual minority status (i.e., outness). DNA methylation-derived outcomes included the following: the extrinsic epigenetic age acceleration clock, telomere length, naive CD4+ T-helper cells, and naive CD8+ T-cytotoxic/suppressor cells. RESULTS: After adjusting for negative affect and recent stimulant use, higher sexual minority stress was associated with a faster extrinsic epigenetic age acceleration clock ( ß = 0.29, p = .030), shorter telomere length ( ß = -0.43, p = .002), and fewer naive CD4+ (ß = -0.57, p < .001) and naive CD8+ T cells ( ß = -0.57, p < .001). Greater outness was associated with higher naive CD4+ ( ß = 0.32, p = .030) and naive CD8+ T cells ( ß = 0.38, p = .008) as well as lower plasma interleukin 6 ( ß = -0.33, p = .027). CONCLUSIONS: Sexual minority stress processes are associated with markers of cellular aging and inflammation in methamphetamine-using sexual minority men living with HIV. Longitudinal research should elucidate biobehavioral mechanisms linking sexual minority stress processes with accelerated cellular aging in those with and without HIV.

Structural Life Instability and Factors Related to Latino Sexual Minority Men's Intention to Engage with Biomedical HIV-Prevention Services.

Latino sexual minority men (LSMM) experience high rates of HIV and co-occurring health inequities. Structural and psychosocial factors may lead to mental health problems and decreased engagement with biomedical HIV-prevention behaviors. This cross-sectional study assessed the extent to which structural life instability is related to biomedical HIV-prevention services engagement (HIV-testing and PrEP uptake) indirectly through psychological distress among 290 LSMM living in Greater Miami. Using hybrid structural equation modeling, significant direct effects from structural life instability to psychological distress emerged, as did effects from psychological distress (i.e., depression and anxiety) to HIV-prevention engagement. Structural life instability had a significant indirect effect to HIV-prevention engagement via psychological distress. Findings show a possible mechanism explaining the relationship between structural life instability and biomedical HIV-prevention engagement among a group of LSMM, a subpopulation at increased susceptibility for HIV acquisition in an U.S. HIV epicenter.

RESUMEN: Los hombres latinos de minorías sexuales (LHLMS) experimentan altos índices de VIH y disparidades de salud concurrentes. Los factores estructurales y psicosociales pueden provocar problemas de salud mental y, a su vez, reducir la participación con los comportamientos biomédicas de prevención del VIH. Este estudio transversal evaluó el grado en qué la inestabilidad estructural de la vida (IEV) está relacionada con la participación de los servicios de prevención del VIH (pruebas del VIH y uso de PrEP) indirectamente a través de la angustia psicológica entre 290 LHLMS que viven en el Gran Miami, un epicentro del VIH. Utilizando modelos de ecuaciones estructurales híbridas, surgieron efectos directos significativos de SLI a la angustia psicológica, al igual que los efectos de la angustia psicológica a la participación en la prevención del VIH. El SLI tuvo un efecto indirecto significativo en la participación en la prevención del VIH a través de la angustia psicológica. Los resultados muestran un posible mecanismo que explica la relación entre el SLI y la participación en la biomédica prevención del VIH.

The shame spiral of addiction: Negative self-conscious emotion and substance use.

BACKGROUND: The bidirectional associations between negative self-conscious emotions such as shame and guilt and substance use are poorly understood. Longitudinal research is needed to examine the causes, consequences, and moderators of negative self-conscious emotions in people who use substances. METHODS: Using parallel process latent growth curve modeling, we assessed bidirectional associations between shame and guilt and substance use (i.e., number of days in the past 30 used stimulants, alcohol to intoxication, other substances, or injected drugs) as well as the moderating role of positive emotion. Emotions were assessed using the Differential Emotions Scale. The sample included 110 sexual minority cisgender men with biologically confirmed recent methamphetamine use, enrolled in a randomized controlled trial in San Francisco, CA. Participants self-reported emotions and recent substance use behaviors over six time points across 15 months. RESULTS: Higher initial levels of shame were associated with slower decreases in stimulant use over time (b = 0.23, p = .041) and guilt was positively associated with stimulant use over time (ß = 0.85, p < .0001). Initial levels of guilt and alcohol use were positively related (b = 0.29, p = .040), but over time, they had a negative relationship (ß = -0.99, p < .0001). Additionally, higher initial levels of other drug use were associated with slower decreases in shame over time (b = 0.02, p = .041). All results were independent of depression, highlighting the specific role of self-conscious emotions. CONCLUSIONS: Shame and guilt are barriers to reducing stimulant use, and expanded efforts are needed to mitigate the deleterious effects of these self-conscious emotions in recovery from a stimulant use disorder.

Syndemics and preexposure prophylaxis are independently associated with rectal immune dysregulation in sexual minority men.

OBJECTIVE: Syndemic conditions have been linked to engagement in receptive condomless anal sex (CAS) and HIV seroconversion. However, little is known about the biological pathways whereby syndemics could amplify vulnerability to HIV and other sexually transmitted infections (STIs). DESIGN: HIV-negative sexual minority men (i.e. gay, bisexual and other MSM) were recruited from four STI clinics in South Florida for a cross-sectional study. METHODS: Participants completed assessments for four syndemic conditions: depression, posttraumatic stress disorder, hazardous alcohol use and any stimulant use (i.e. any self-reported use or reactive urine toxicology results). Cytokine and chemokine levels were measured using LEGENDplex from the rectal swabs of 92 participants reporting receptive CAS and no antibiotic use in the past three months. RESULTS: After controlling for age, race/ethnicity, preexposure prophylaxis (PrEP) use and number of receptive CAS partners, a greater number of syndemic conditions was associated with higher levels of rectal cytokines/chemokines relevant to immune activation, inflammation and the expansion and maintenance of T-helper 17 target cells, including rectal interferon-gamma (ß = 0.22; P = 0.047), CXCL-8 (ß = 0.24; P = 0.025) and interleukin-23 (ß = 0.22; P = 0.049). Elevations in rectal cytokine or chemokine levels were most pronounced among participants experiencing two or more syndemic conditions compared with those experiencing no syndemic conditions. PrEP use was independently associated with elevations in multiple rectal cytokines/chemokines. CONCLUSION: Syndemic conditions could increase biological vulnerability to HIV and other STIs in sexual minority men by potentiating rectal immune dysregulation.

Tryptophan depletion predicts lower positive affect in sexual minority men living with HIV who use methamphetamine.

This longitudinal study with 76 sexual minority men living with HIV who use methamphetamine examined whether dysregulation of essential amino acid precursors for neurotransmitters at baseline predicted positive and negative affect at 15 months. After controlling for covariates including baseline positive affect, a higher baseline kynurenine/tryptophan (K/T) ratio independently predicted lower positive affect at 15 months (ß = - 18.31; 95% CI = - 35.35, - 1.27; p = 0.036). Future clinical research should examine whether bio-behavioral interventions targeting tryptophan degradation could optimize treatments for people living with co-occurring HIV and stimulant use disorders.

Syndemics and salivary inflammation in people living with HIV/AIDS.

OBJECTIVE: People living with HIV/AIDS (PLWHA) are disproportionally exposed to a host of structural, community, and individual-level physical and psychosocial stressors also termed 'syndemic conditions.' The current study aimed to examine the association between experiencing syndemic conditions and physiological stress response and be associated with bodily inflammation, including Interlekin-6 (IL-6) and C-reactive protein (CRP) in PLWHA. DESIGN: Participants (N = 103) were recruited from a public HIV clinic. They provided saliva samples of IL-6 and CRP and completed psychosocial measures. MAIN OUTCOME MEASURES: Levels of circulating salivary IL-6 and CRP. RESULTS: When predictors (birth country, recent housing instability, and incarceration history) were simultaneously entered into a regression model, only incarceration history was negatively associated with IL-6 [b = -.27, t(98) = -3.11, p = .002]. For CRP, the resulting regression model was not significant, [F(3, 98) = 2.23, p = .090]. CONCLUSION: Although we had expected higher levels of syndemics to be associated with higher levels of circulating inflammation, in our sample, length of incarceration was associated with lower levels of circulating IL-6. Findings are therefore suggestive of a stress response disruption resulting in a negative feedback loop as the long-term impact of chronic stress on inflammation.

Trauma exposure, PTSD, and suboptimal HIV medication adherence among marginalized individuals connected to public HIV care in Miami.

Individuals living with HIV report disproportionately high levels of trauma exposure and PTSD symptoms, both which have been associated with suboptimal ART adherence. Often conflated, the question arises as to which construct is driving subsequent HIV self-care behavior. Given the HIV disparities among Black and Hispanic/Latinx individuals, and that Miami is a geographic region with a high racial/ethnic minority make up and a unique socioeconomic environment, it is important to explore factors related to HIV outcomes in Miami to mitigate its uncontrolled epidemic. This study aimed to examine the association of trauma exposure, PTSD symptoms, and relevant additional key factors with adherence to ART among a sample of majority Black and Hispanic/Latinx individuals who are economically marginalized receiving public HIV care in Miami, FL (N = 1237) via a cross-sectional survey. Sequential linear regression was used to examine the study aim in four blocks: (1) trauma, (2) PTSD symptoms, and key covariates of ART adherence including (3) depression and substance use (potential psychological covariates), and (4) indicators of socioeconomic status (potential structural covariates). In the first block, trauma exposure was associated with worse adherence. However, in the second block, the association with trauma dropped and PTSD was significantly associated with worse adherence. Of note, for those experiencing high levels of trauma exposure, adherence was negatively impacted regardless of PTSD. When other key factors associated with adherence were entered in the third and fourth blocks, neither trauma exposure nor PTSD were uniquely significant. In this final model, depression, substance use, and unstable housing were uniquely associated with worse adherence. Trauma-informed models of HIV care that holistically address co-occurring factors are warranted to cater to communities with HIV health disparities and keep them from falling off the HIV care continuum.

High Levels of Syndemics and Their Association with Adherence, Viral Non-suppression, and Biobehavioral Transmission Risk in Miami, a U.S. City with an HIV/AIDS Epidemic.

Miami is a Southeastern United States (U.S.) city with high health, mental health, and economic disparities, high ethnic/racial diversity, low resources, and the highest HIV incidence and prevalence in the country. Syndemic theory proposes that multiple, psychosocial comorbidities synergistically fuel the HIV/AIDS epidemic. People living with HIV/AIDS in Miami may be particularly affected by this due to the unique socioeconomic context. From April 2017 to October 2018, 800 persons living with HIV/AIDS in a public HIV clinic in Miami completed an interviewer-administered behavioral and chart-review cross-sectional assessment to examine the prevalence and association of number of syndemics (unstable housing, low education, depression, anxiety, binge drinking, drug use, violence, HIV-related stigma) with poor ART adherence, unsuppressed HIV viral load (≥ 200 copies/mL), and biobehavioral transmission risk (condomless sex in the context of unsuppressed viral load). Overall, the sample had high prevalence of syndemics (M = 3.8), with almost everyone (99%) endorsing at least one. Each syndemic endorsed was associated with greater odds of: less than 80% ART adherence (aOR 1.64, 95% CI 1.38, 1.98); having unsuppressed viral load (aOR 1.16, 95% CI 1.01, 1.33); and engaging in condomless sex in the context of unsuppressed viral load (1.78, 95% CI 1.30, 2.46). The complex syndemic of HIV threatens to undermine the benefits of HIV care and are important to consider in comprehensive efforts to address the disproportionate burden of HIV/AIDS in the Southern U.S. Achieving the 90-90-90 UNAIDS and the recent U.S. "ending the epidemic" targets will require efforts addressing the structural, social, and other syndemic determinants of HIV treatment and prevention.

Post-traumatic Stress Disorder, Cocaine Use, and HIV Persistence.

BACKGROUND: Post-traumatic stress disorder (PTSD) and stimulant use disorders are highly prevalent, commonly co-occur, and predict faster clinical HIV progression. However, scant research has examined if PTSD and cocaine use are associated with the HIV reservoir that persists in immune cells, lymphoid tissue, and organs of people living with HIV that are receiving effective treatment. METHOD: This cross-sectional study enrolled 48 HIV-positive persons with sustained undetectable viral load (< 20 copies/mL) in the past year to examine the associations of PTSD and recent cocaine use with two measures of HIV persistence in immune cells: (1) proviral HIV DNA and (2) cell-associated (CA)-HIV RNA. RESULTS: Greater PTSD symptoms were significantly associated with lower proviral HIV DNA (r = - 0.30, p = 0.041) but not with CA-HIV RNA. Greater severity of PTSD symptom clusters for intrusions (Standardized Beta = - 0.30, p = 0.038) and hyperarousal (Standardized Beta = - 0.30, p = 0.047) were independently associated with lower proviral HIV DNA. Although participants with recent cocaine use had a significantly shorter duration of sustained undetectable HIV viral load (19.9 versus 26.9 months; p = 0.047), cocaine use was not significantly associated with proviral HIV DNA or CA-HIV RNA. CONCLUSION: Further research is needed to examine the potentially bi-directional pathways linking PTSD symptom severity and HIV persistence.

Pathways to Health: an Examination of HIV-Related Stigma, Life Stressors, Depression, and Substance Use.

BACKGROUND: Despite antiretroviral treatment (ART) being an efficacious treatment for HIV, essentially making it a chronic non-terminal illness, two related and frequent concerns for many people living with HIV/AIDS (PLWHA) continue to be HIV-related stigma and life stress. These two variables are frequently associated with depression, substance use, and poorer functional health. Studies to date have not fully examined the degree to which these constructs may be associated within one model, which could reveal a more nuanced understanding of how HIV-related stigma and life stress affect functional health in PLWHA. METHODS: The current study employed hybrid structural equation modeling to examine the interconnectedness and potential indirect relationships of HIV-related stigma and life stress to worse health through substance use and depression, controlling for ART adherence and age. Participants were 240 HIV-infected individuals who completed a biopsychosocial assessment battery upon screening for an RCT on treating depression in those infected with HIV. RESULTS: Both HIV-related stigma and stressful life events were directly related to depression, and depression was directly related to health. There were significant indirect effects from stigma and stress to health via depression. There were no significant effects involving substance use. CONCLUSION: It is important to continue to develop ways to address stigma, stressful life events, and their effects on distress in those living with HIV. Expanding our knowledge of disease progression risk factors beyond ART adherence is important to be able to design adjuvant interventions, particularly because treatment means that people living with HIV have markedly improved life expectancy and that successful treatment means that HIV is not transmittable to others.

A Systematic Review of Interventions to Reduce Problematic Substance Use Among Transgender Individuals: A Call to Action.

Persons who are transgender (i.e., individuals who are assigned one sex at birth, but who do not identify with that sex) are at elevated risk for developing problematic substance use. Recent studies indicate that transgender persons have high rates of alcohol use, illicit drug use, and nonmedical use of prescription drugs and evince more severe misuse of these substances compared with nontransgender individuals. Despite the high rates of substance use among transgender persons and the multiple conceptual and narrative recommendations for substance use treatments, there is a lack of consensus or awareness of empirically tested interventions and programs effective for this population. Thus, it is critical to examine current substance use interventions for transgender individuals to identify gaps in the field and to immediately put forth efforts to reduce problematic substance use. This systematic review is the first to attempt a comprehensive identification and synthesis of the available evidence on interventions for reducing problematic substance use among transgender persons. Reflective of the state of the field regarding transgender care for substance use, we found a deficiency of studies to include in this systematic review (n=2). Perhaps the most important conclusion of this review is that well-designed, theoretically informed culturally sensitive research focused on developing and rigorously testing interventions for substance use among transgender individuals is alarmingly scarce. This review discusses barriers to intervention design and synthesizes treatment recommendations for future work.

The Duality of Oral Sex for Men Who Have Sex with Men: An Examination Into the Increase of Sexually Transmitted Infections Amid the Age of HIV Prevention.

Several studies suggest that the increase in sexually transmitted infections (STIs) among men who have sex with men (MSM) could be due, in part, to human immunodeficiency virus (HIV) risk reduction strategies, which include engaging in oral sex over anal sex. The aims of this study were to evaluate oral sex behaviors and STI diagnoses and to investigate the potential dual role of oral sex as being protective for HIV, yet perpetuating STI transmission among MSM. We analyzed records from 871 MSM presenting to the Rhode Island STI Clinic between 2012 and 2015. We compared outcomes in men engaging in two HIV protective oral sex behaviors: (1) HIV/STI outcomes by men engaging only in oral sex versus those that did not, and (2) HIV/STI outcomes by men engaging in condomless oral sex with 100% condom use for all other sex acts versus those that did not. Men engaging in HIV protective oral sex behaviors were more likely to be HIV negative compared to men not engaging in them (99% vs. 93%, p < 0.01). In contrast, there was no significant difference in STI diagnoses between those that engaged in HIV protective oral sex behaviors and those that did not. The findings provide evidence to support the unique duality of oral sex: decreased risk for HIV and perpetuation of STI risk. Promotion of routine STI testing, including extragenital sites, is critical to address STI prevention among MSM. In the age of HIV prevention, addressing the ambiguous risks of discrete sex acts would be beneficial for both HIV and STI prevention education for MSM.

Implementation of Preexposure Prophylaxis for Human Immunodeficiency Virus Prevention Among Men Who Have Sex With Men at a New England Sexually Transmitted Diseases Clinic.

BACKGROUND: Preexposure prophylaxis (PrEP) is efficacious in preventing human immunodeficiency virus (HIV) among men who have sex with men (MSM). We assessed PrEP uptake among MSM presenting for services at a sexually transmitted diseases (STD) clinic. METHODS: Men who have sex with men presenting to the Rhode Island STD Clinic between October 2013 and November 2014 were educated about, and offered, PrEP. We categorized PrEP engagement using an implementation cascade to describe gaps in uptake which described MSM who: (1) were educated about PrEP, (2) indicated interest, (3) successfully received follow-up contact, (4) scheduled an appointment, (5) attended an appointment, and (6) initiated PrEP (ie, received a prescription). Bivariate and multivariable logistic regression models were used to examine predictors of PrEP initiation. RESULTS: A total of 234 MSM were educated about PrEP; of these, 56% expressed interest. Common reasons for lack of interest were low HIV risk perception (37%), wanting more time to consider (10%), concern about side effects (7%), and financial barriers (3%). Among those interested, 53% followed up. Of those, 51% scheduled an appointment. The most common reason patients did not schedule an appointment was low HIV risk perception (38%). Seventy-seven percent of those with an appointment attended the appointment; of those, 93% initiated PrEP. Patients with higher HIV-risk perception (adjusted odds ratios, 2.17; 95% confidence interval, 1.29-3.64) and a history of sex with an HIV-positive partner (adjusted odds ratios, 7.08; 95% confidence interval, 2.35-21.34) had significantly higher odds of initiating PrEP. CONCLUSIONS: Low HIV-risk perception was the most significant barrier to PrEP uptake among MSM attending a public STD clinic.

The role of gender affirmation in psychological well-being among transgender women.

High prevalence of psychological distress, including greater depression, lower self-esteem, and suicidal ideation, has been documented across numerous samples of transgender women and has been attributed to high rates of discrimination and violence. According to the gender affirmation framework (Sevelius, 2013), access to sources of gender-affirmative support can offset such negative psychological effects of social oppression. However, critical questions remain unanswered in regards to how and which aspects of gender affirmation are related to psychological well-being. The aims of this study were to investigate the associations between three discrete areas of gender affirmation (psychological, medical, and social) and participants' reports of psychological well-being. A community sample of 573 transgender women with a history of sex work completed a one-time self-report survey that assessed demographic characteristics, gender affirmation, and mental health outcomes. In multivariate models, we found that social, psychological, and medical gender affirmation were significant predictors of lower depression and higher self-esteem while no domains of affirmation were significantly associated with suicidal ideation. Findings support the need for accessible and affordable transitioning resources for transgender women in order to promote better quality of life among an already vulnerable population. As the gender affirmation framework posits, the personal experience of feeling affirmed as a transgender person results from individuals' subjective perceptions of need along multiple dimensions of gender affirmation. Personalized assessment of gender affirmation may thus be a useful component of counseling and service provision for transgender women.
