STD Risk Reduction for Heterosexual Methamphetamine Users
Substance-Related DisordersHIV Infections1 moreThis study will evaluate the effectiveness of a sexual risk reduction intervention in reducing sexual risk behavior in HIV uninfected, heterosexual people who use methamphetamine.
Lay Health Advisors for Sexually Transmitted Disease Prevention
SyphilisGonorrhea2 moreNon-professional community leaders may be at a great advantage in reaching otherwise hard to reach populations for the purpose of advising on sexually transmitted disease (STD) prevention (lay health advisors), health care access, and model health behavior. Latino migrant farm workers are at increased risk for STD and might benefit from such lay health advisors. The study will examine whether this strategy is a useful one for STD prevention in Latino migrant farm workers in rural and small town areas of North Carolina.
Efficacy Study of the Vaginal Gel Carraguard to Prevent HIV Transmission
HIV InfectionsAIDS2 moreThe purposes of this study are to determine whether Carraguard® Gel can prevent the transmission of HIV when used during vaginal intercourse, and to confirm that the gel is safe for vaginal use.
Reducing Vaginal Infections in Women
Bacterial DiseasesOther Mycoses1 moreThe purpose of this study is to see if taking medication once a month can help to decrease the risk of vaginal infections. Additionally, researchers will study whether personal habits, such as douching, bathing, and sexual practices can influence the risk of vaginal infections. Vaginal infections may influence the risk of becoming infected with HIV-1 and other sexually transmitted diseases (STDs). Study participants will include 400 female prostitutes ages 16 and older, living in Mombasa. Study procedures will include sexual behavior questions, physical examinations including pelvic exams, testing of vaginal and cervical secretions for STDs, urine collection and blood samples. Participants will receive 2 different types of pills to treat vaginal infections (metronidazole or fluconazole) or placebo (contains no medication). Participants will be involved in study related procedures for 1 year and will return to the study clinic at one month intervals.
The S.A.F.E. Study : Computer-Aided Counseling to Prevent Teen Pregnancy/Sexually Transmitted Diseases...
PregnancySexually Transmitted DiseasesThis is a randomized clinical trial assessing the efficacy of two types of counseling (Computer-Assisted Motivational Intervention [CAMI] versus Didactic Educational Counseling [DEC]) to see which can better reduce female adolescents' risk taking behaviors that put them at risk for unintended pregnancy and sexually transmitted diseases (STDs). The intervention phase consists of three 30-minute counseling sessions over the first 6 months followed by a visit every three months during the 12 month follow up phase. We, the researchers, hypothesize that the CAMI will decrease the proportion of subjects who engage in any intercourse that is poorly protected against pregnancy and against STDs.

HIV/AIDSSexually Transmitted DiseasesThe objectives of the study are to assess the feasibility, reach and preliminary efficacy of a brief intervention that trains Black men who have sex with men [referred to as Index] (a) to use home-based testing for HIV and sexually transmitted infections and (b) promote home-based testing to their peers and sexual partners.
Same-Day PrEP Initiation and Sexual Health for Transgender Women
HIVPrEP3 moreTransgender women (trans women; assigned male sex at birth but identify as female) are at high risk for HIV infection, and are an important, under-researched population in sub-Saharan Africa. Trans women have a 13 times greater risk of acquiring HIV than adults aged 15-49 years in the general population, and in Africa, trans women have nearly twice the HIV prevalence (25%) of men who have sex with men [MSM] (14%). Oral pre-exposure prophylaxis (PrEP) is an effective prevention tool that could change the trajectory of the HIV epidemic among the 25 million trans women globally, yet its use has been suboptimal in this vulnerable population. Same-day PrEP initiation is feasible and acceptable and improves retention in PrEP care in resource-rich settings. Same-day initiation of emtricitabine/tenofovir alafenamide (F/TAF), a new PrEP regimen, has not to our knowledge previously been evaluated as PrEP in African trans women. F/TAF is potentially more efficacious and safer than emtricitabine/tenofovir disoproxil fumarate (F/TDF) as shown in the recent DISCOVER trial. However, concerns about drug-drug interactions between feminizing hormonal therapy (FHT) and PrEP are a key potential adherence barrier for trans women. While PrEP drugs do not lower FHT levels, FHT decreases plasma TFV and (emtricitabine) FTC levels. Little is known about FHT use among African trans women taking F/TAF or how concerns about F/TAF-FHT interactions may influence PrEP adherence. Moreover, interventions to support PrEP adherence in this population are needed. Feedback about PrEP use has been shown to potentially improve PrEP adherence among MSM but has not been utilized among trans women. Key knowledge gaps include: 1) whether same-day PrEP can be successfully implemented for African trans women, 2) the impact of drug-level feedback on PrEP adherence, and 3) how use of FHT may influence PrEP adherence. To address these questions, this protocol describes a randomized trial to evaluate the feasibility and acceptability of same day initiation of F/TAF PrEP, evaluate impact of drug-level feedback on PrEP adherence and characterize PrEP persistence, and in-depth interviews to explore how self-care interventions for sexual health influence prevention choices among trans women and their sexual partners. This will be the first clinical trial, to our knowledge, to evaluate F/TAF as PrEP for HIV-negative trans women in sub-Saharan Africa.

Optimizing a Multi-Modal Intervention to Reduce Health-Risking Sexual Behaviors: Component Selection...
Sexually Transmitted InfectionsPregnancy2 moreThe goal of this project is to evaluate the components of the app-based intervention Mission Wellness to reduce health-risking sexual behaviors (HRSBs; e.g., condom non-use, multiple sexual partners) in active-duty members of the US Military to improve their sexual and reproductive health (SRH) and readiness to serve. Following the multiphase optimization strategy (MOST) framework, factorial component selection experiments (CSEs) will be conducted to evaluate which five experimental intervention components (i.e., Narratives, Skills, Scenarios, Future, and Risk) elicit the greatest improvements in the outcomes of interest given key constraints.
