Filter by:Black young men who have sex with men (BYMSM) are at high risk for contracting and transmitting HIV, and represent a priority population for developing effective interventions. Within the House Ball community (HBC), a clandestine subculture of the Black gay community, HIV is highly stigmatized. This stigma, coupled with high HIV prevalence rates and elevated levels of undiagnosed/untreated HIV infection, places BYMSM in HBCs at incredible risk for HIV infection. Community-level interventions that target social norms, behavior, and stigma in the HBC are sorely needed in order to make a broader impact among BYMSM. Building on prior work in the community, this study proposes to launch an innovative Effectiveness-Implementation Hybrid Type 2 trial to examine the effectiveness and implementation of a community-level HIV prevention intervention (called POSSE) based on popular opinion leader (POL) models across two cities with similar HBCs, Chicago and Philadelphia. The proposed study has two specific aims: 1) To determine the effectiveness of a POL intervention, POSSE, to decrease sexual risk behavior (UAI), STIs and HIV stigma among BYMSM in the HBC; and 2) To evaluate the processes, strategies, barriers and facilitators for the implementation of POSSE delivered across two distinct metropolitan areas with high HIV prevalence among BYMSM and similar House Ball Communities. To examine these aims, the investigators will first use social network strategies to identify, screen, and recruit POLs (n=75) from the Philadelphia HBC. The investigators will then gather baseline behavioral and biological (HIV/STI testing) data in both Chicago and Philadelphia (n=100 BYMSM per city) and train the Philadelphia POLs to implement the POSSE intervention. The investigators will conduct an implementation-focused process evaluation to assess fidelity to the POSSE intervention; number, content, spread, and acceptability of risk reduction messages; age appropriateness of the messages; acceptability of the overall intervention; and barriers/facilitators to implementation. Next, the investigators will complete follow-up assessments every 6 months post- intervention in both cities (n=100 BYMSM per city at each assessment point). The investigators will also assess behavior change in those delivering the intervention (POLs) at each assessment point. The investigators will conduct implementation-focused qualitative interviews with POLs (n=15) and community participants (n=30) from Philadelphia. Last, the investigators will implement POSSE in Chicago by repeating the steps outlined above, continuing assessments in both cities, and conducting qualitative interviews in Chicago.
Latino adolescents are at high risk for HIV/AIDS, other sexually transmitted infections (STIs), and unintended pregnancies. Puerto Rican adolescents, in particular, experience disparities in these areas, yet few adolescent and even fewer parent interventions have been developed to address these important issues with this underserved population. Parent-adolescent programs are an effective approach to reduce adolescent sexual risk behavior and associated negative consequences. A web-based parent communication intervention provides an opportunity to strengthen and enhance programs that are designed for adolescents by providing additional support for safer sex decisions, and to increase parents' access to sexual health education programs by decreasing barriers that keep them from participating in these interventions (e.g., low cost, can be viewed privately, at parents convenience, minimizes competing time with work and family). The purpose of this proposed study is to evaluate a brief theoretically informed (i.e., Ecodevelopmental Theory, Theory of Reasoned Action/Planned Behavior, Social Cognitive Theory 1-6), culturally appropriate, and linguistically tailored web-based parental communication program, Cuídalos ("Take care of them"), designed to improve parent-adolescent sexual communication and reduce adolescent sexual risk behavior. Recent findings from an NIH funded R21 randomized control trial (RCT) testing a brief computer-based version of the Cuídalos program indicated that the program increased parent-adolescent general communication and sexual risk communication with English and Spanish speaking U.S. Latinos. Further, despite limited or no previous computer use, parents reported they liked and learned from the program, and that it was easy to use and accessible.
This is a multi-center, randomized, controlled, open clinical trial. The trial will be carried out in five provinces in China. Pregnant women with HIV infection and at high risk of mother-to-child transmission of HIV will be identified. Their newborn babies who are at high risk HIV infection will be recruited and randomized into intervention and control groups. Children in intervention groups will receive ART and intensive HIV testing after birth. Children in control group will receive routine prevention of mother-to-child transmission services. All the included children will be followed up and their development and infection status will be recorded and compared.
This study will examine the efficacy of a combined HIV and microfinance intervention to reduce biologically confirmed sexually transmitted infections (STIs), and new incidence of HIV and HCV, as well as reported sexual and drug risk behaviors among 520 women who have injected drugs in the past year and who engage in sex trading in Temirtau and Pavlodar, Kazakhstan. The proposed study builds on findings from an R34 by the investigative team testing a combination HIV prevention and microfinance intervention. Building on successful protocols and significant results, we will randomly assign 520 women who inject drugs and engage in sex trading from Temirtau and Pavlodar, Kazakhstan to either (1) a 4 session HIV prevention intervention combined with a 6 session financial literacy intervention, enrollment in an existing vocational training program and receipt of matched savings (HIVRR+MF); or to the 4 session HIV prevention intervention alone. The HIVRR intervention is guided by social cognitive theory. The HIVRR+MF intervention integrates asset theory with social cognitive theory. The MF includes: 1) financial literacy; 2) vocational training; and 3) micro-savings to support transition to a more permanent employment status. We hypothesize that increasing financial literacy, enhancing vocational skills required to fill marketable positions in the local economy, and beginning a personal savings program, combined with HIV risk reduction, will lead to significant reductions in study outcomes compared to an HIVRR intervention without a microfinance intervention.
The aim of this study is to compare the effectiveness of two vaccination strategies against Hepatitis B virus (HBV) in subjects already infected with human immunodeficiency virus (HIV). Researchers plan to determine the optimal vaccination strategy for achieving protective immunity to HBV infection in HIV-infected adults attending Mulago Hospital's HIV care clinic. Primary objectives are to assess: 1. The role of CD4-cell count and HIV viral loads on the HBV vaccine response. 2. The role of highly active antiretroviral therapy (HAART) on the HBV vaccine response. The secondary objective is to evaluate whether lack of HAART is associated with high rates of loss to follow-up.
