Background: Concurrent psychosocial problems may synergistically increase the risk of HIV infection (syndemics), representing a challenge for prevention. We aimed to evaluate the prevalence and associated factors of syndemics among men who have sex with men (MSM) and transgender women (TGW) enrolled in the Brazilian pre-exposure prophylaxis demonstration study (PrEP Brasil Study). Methods: Secondary cross-sectional analysis of the PrEP Brasil Study was performed.

Efficacy, safety, and effect on sexual behaviour of on-demand pre-exposure prophylaxis for HIV in men who have sex with men: an observational cohort study
Background Data for on-demand pre-exposure prophylaxis (PrEP) are scarce. We implemented a cohort study to assess its efficacy, safety, and effect on sexual behaviour. Methods We invited men and transgender women who have sex with men, previously enrolled in the randomised placebo-controlled ANRS IPERGAY trial at seven sites (six in France and one in Canada), to participate in an open-label extension with on-demand tenofovir disoproxil fumarate (300 mg) and emtricitabine (200 mg) to be taken before and after sexual intercourse.

Unveiling of HIV dynamics among transgender women: a respondent-driven sampling study in Rio de Janeiro, Brazil
Background The burden of HIV in transgender women (transwomen) in Brazil remains unknown. We aimed to estimate HIV prevalence among transwomen in Rio de Janeiro and to identify predictors of newly diagnosed HIV infections. Methods We recruited transwomen from Rio de Janeiro, Brazil, by respondent-driven sampling. Eligibility criteria were self-identification as transwomen, being 18 years of age or older, living in Rio de Janeiro or its metropolitan area, and having a valid peer recruitment coupon.

Study Objective Produce Girl Talk, a free smartphone application containing comprehensive sexual health information, and determine the application's desirability and appeal among teenage girls. Design, Setting, Participants, and Interventions Thirty-nine girls ages 12 to 17 years from Rhode Island participated in a 2-phase prospective study. In phase I, 22 girls assessed a sexual health questionnaire in focus groups. In phase II, 17 girls with iPhones used Girl Talk for 2 weeks and answered the revised sexual health questionnaire and interview questions before and after use.

Distinguishing hypothetical willingness from behavioral intentions to initiate HIV pre-exposure prophylaxis (PrEP): Findings from a large cohort of gay and bisexual men in the U.S.
Rationale Much of the data on the acceptability of HIV Pre-Exposure Prophylaxis (PrEP) is based on willingness to take PrEP (i.e., hypothetical receptivity) rather than actual intentions (i.e., planned behavioral action) to do so. Objective We sought to examine differences between hypothetical willingness and behavioral intentions to begin PrEP in a national sample of gay and bisexual men (GBM) across the U.S.

Human Immunodeficiency Virus, Other Sexually Transmitted Infections, and Sexual and Reproductive Health in Lesbian, Gay, Bisexual, Transgender Youth
Lesbian, gay, bisexual, transgender (LGBT), and questioning youth represent a diverse population who are affected by many sexual health inequities, including increased risk for human immunodeficiency virus (HIV) and sexually transmitted infections (STIs). To provide comprehensive sexual health care for LGBT youth, providers should set the stage with a nonjudgmental, respectful tone. Providers should be competent in recognizing symptoms of STIs and HIV and aware of the most up-to-date screening guidelines for LGBT youth.

Project PRIDE: A Cognitive-Behavioral Group Intervention to Reduce HIV Risk Behaviors Among HIV-Negative Young Gay and Bisexual Men
Young gay and bisexual men are at increased risk for human immunodeficiency virus (HIV) infection. Research suggests that the stress associated with being a stigmatized minority is related to negative mental health outcomes, substance use, and condomless sex. However, interventions aimed at reducing HIV risk behaviors in young gay and bisexual men have failed to address these important variables. The purpose of the present paper is to assist cognitive and behavioral therapists who work with young gay and bisexual men to conduct therapy for stress management and HIV prevention.

Gay, bisexual, and other men who have sex with men (MSM) continue to have disproportionately high burdens of HIV infection in countries of low, middle, and high income in 2016. 4 years after publication of a Lancet Series on MSM and HIV, progress on reducing HIV incidence, expanding sustained access to treatment, and realising human rights gains for MSM remains markedly uneven and fraught with challenges.

Adolescents with a minority sexual orientation (e.g., lesbian, gay, and bisexual) are more likely to use substances than their heterosexual peers. This study aimed to increase understanding of the development of drug use in this vulnerable population by: 1) comparing longitudinal patterns of past-year illicit drug use (e.g., marijuana, cocaine, and ecstasy) and misuse of prescription drugs among minority sexual orientation youth relative to heterosexual youth and, 2) examining how sexual orientation sub-group, gender, and age relate to variation in the risk of drug use.
