Filter by:This study will develop and test an interactive mobile messaging intervention to improve engagement in care related to Pre-exposure Prophylaxis (PrEP) and decrease HIV risk behaviors for Black men who have sex with men living in the Southern U.S. The mobile messaging intervention will include interactive text messaging and free, publicly available links to websites and YouTube videos. During the intervention participants will gain information about their health, improve motivation for engagement in PrEP related care, and build skills for healthy behaviors. Participants will also receive intervention materials to help decrease frequent barriers to care. If the intervention is found to be effective, it can be tested in a larger study and then disseminated.
This study will evaluate the impact of hormonal contraceptives on HIV risk associated with changes to the innate immunity in the female genital tract in a cross-sectional study. HIV risk will be evaluated by the capacity of cervical tissue to replicate HIV when challenged ex vivo and correlated to the number of CD4 T cells, DCs, and macrophages; the capacity of cervicovaginal fluid to inhibit HIV will be correlated to soluble mucosal mediators, and the vaginal microbiota. The lower genital tract samples will be collected from 120 adolescents aged 18-19 (40 using no hormonal contraception, 40 using ENG-I, 40 using LNG-IUS). For comparison, 90 adult women aged 25-45 will be equally distributed between the same groupings.
This study is designed as an individual randomized trial among 150 HIV-infected adolescents aged 10-24 years who have been on ART for >6 months and will be randomized in a 1:1 fashion to one of two arms: 1) the intervention arm (POC) will receive a POC VL test with adherence counseling informed by the VL result the same day as testing vs. 2) the standard-of-care arm (SOC) will receive a standard laboratory-based test with adherence counseling informed by the VL result 1 month later. The study tests an intervention, POC VL testing, which reduces the time between sample collection and participant receipt of results, thus decreasing the number of steps in the HIV treatment cascade. This intervention was developed to addresses health systems-based barriers which delay clinic, laboratory, and data management processes for VL monitoring for HIV-infected adolescents. Our results will contribute to research on whether POC VL testing is a feasible testing method which could be incorporated into health systems in similar resource-limited settings and whether it can improve outcomes among HIV-infected adolescents.
The investigators will conduct a randomized controlled trial of Group Care in the GHESKIO Community Center versus Individual Care in the GHESKIO Adolescent Clinic for 160 HIV-infected adolescent girls age 16-23 years in Haiti (80 adolescents per arm). Group Care includes receiving integrated clinical and social support services in groups of 5-8 adolescents at a monthly visit. The primary outcome is retention in HIV care at 12 months after randomization.
Young gay, bisexual, and other men who have sex with men (YMSM) are the only risk group in which rates of new HIV infections are on the rise. There has been a relative dearth of research dedicated to understanding these health disparities between gay/bisexual and heterosexual youth, and even less has focused on identifying factors that might promote resilience against negative health outcomes. Understanding both risk factors and processes of resilience is critical in developing efficacious interventions to improve health in this population. Through a grant from the National Institutes of Health, the investigators completed formative research with young male couples. Qualitative interviews identified preferences for couples-based intervention format and content. While coupled YMSM expressed some interest in HIV prevention, they were most interested in building relationship skills. Coupled YMSM preferred group-based interventions in order to meet and learn from other couples but had concerns about discussing personal topics in groups. Quantitative analyses found that the rate of condomless sex in couples increased from adolescence to young adulthood. Further, the influence of older partners, partner violence, and drinking before sex were strongest in emerging adulthood. Informed by these, the investigators developed 2GETHER, which aims to reduce HIV transmission risk in couples by enhancing relationship functioning. 2GETHER is a four session program. The first two sessions are group sessions aimed at skills building, and the second two sessions are individualized couple sessions aimed at skills implementation. Modules address communication skills, coping with stress (both general and sexual minority-specific stress), relationship sexual satisfaction, and HIV transmission risk within the dyad and with outside partners. 2GETHER was designed to address HIV transmission risk in couples regardless of HIV status; couples learn to use behavioral and biomedical approaches to prevent both HIV acquisition (e.g., HIV testing, condom use, pre-exposure prophylaxis) and transmission (e.g., medication adherence to reduce viral load), with an overarching emphasis on the health of the couple. The investigators completed a pilot trial of 2GETHER with funding from Northwestern University. The pilot trial enrolled 57 couples (N=114) and demonstrated feasibility, acceptability, and preliminary efficacy of 2GETHER. This pilot trial used a non-randomized pre-/post-test design because the goal was to evaluate feasibility, acceptability and preliminary effects in a large number of diverse couples to inform a future efficacy RCT. Post-test occurred 2 weeks post-intervention, or ~2 months post-baseline. The pilot trial recruited a diverse sample of couples in less than one year and each program module receive high ratings of acceptability during post-sessions evaluation and an exit interview. At the 2-week post-test, the investigators observed significant decreases in HIV risk behavior, improvements in motivation to reduce HIV risk, and improvements in relationship investment. The current study will conduct a randomized controlled trial (RCT) to test the efficacy of 2GETHER, a novel couples-based intervention for young men who have sex with men (YMSM) that aims to reduce HIV transmission risk by optimizing relationship functioning. This RCT will be implemented online; both the experimental and control condition will be administered via video-conferencing technology to couples across the United States. The investigators will conduct this RCT with 200 dyads (total individual N=400), who will be randomized to receive the 2GETHER intervention or existing public health practice (PHP). PHP differs depending on the HIV status of individuals in the dyad. Couples in which both members are HIV-negative will receive the single-session Couples-Based HIV Counseling and Testing (CHCT) protocol. Couples in which both members are HIV-positive will receive the single session Life-Steps medication adherence protocol. Couples with discordant HIV statuses will receive both interventions jointly.
This project will collect quantitative pilot data that will allow the characterization of uptake and binding of 18F-AV-1451 (also known as F 18 T807, also known as T807, also known as 7-(6-fluoropyridin-3-yl)-5H-pyrido[4,3-b]indole), a novel tau imaging compound, in older HIV+ individuals with and without HAND and matched HIV uninfected (HIV-) controls. The primary goal is to develop this highly promising tau imaging technique as an biomarker of cognitive decline in HIV+ individuals. The investigators will obtain preliminary data that will support the possibility of detecting early brain pathological changes due to HIV. Data generated from this study will be used for submission of National Institutes of Health (NIH) grants comparing tau deposition in HAND compared to other neurodegenerative disorders. It is hypothesized that specific topographies will help distinguish these neurodegenerative disorders in older individuals.
The Primary Objective of this study is to compare the effectiveness of HIV clinic-based extended-release Naltrexone (XR-NTX) in decreasing substance use and increasing HIV viral suppression in HIV-infected participants with opioid use disorder to Treatment as Usual in this population.
The purpose of this study is to compare the incidence of Zika virus (ZIKV) infection among pregnant women with and without Human Immunodeficiency Virus (HIV) infection and to determine the risk of adverse maternal and child outcomes associated with ZIKV/HIV co-infection across clinical sites in the continental United States (U.S.), Puerto Rico (P.R.) and Brazil.
This randomized controlled trial was implemented to evaluate the effect of integrating rapid Hepatitis C (HCV) testing into a pre-existing screening program for Human Immunodeficiency Virus (HIV) on HIV test acceptance and diagnosis of both HCV and HIV. A sample of 478 adults in a New York City Emergency Department participated in the study. Participants were randomized to receive either an offer of bundled HIV/HCV testing or HIV testing alone. Public Health Advocates approached eligible patients in the Emergency Department, performed HIV and HCV raid testing, and delivered test results to participants with post-test counseling. The primary outcome, HIV test acceptance, was compared between the two groups to evaluate whether the addition of an HCV test adversely impacted participants' consent to test for HIV. Questionnaires were also distributed to participants to assess HCV knowledge.
Specific aims of the 1-year project are to pilot test the disclosure support intervention by (a) evaluating acceptability and feasibility with a preliminary randomized trial among 10 HIV+ mothers (5 in the intervention group and 5 in the treatment as usual (TAU) group) and (b) assessing outcomes in mothers (quality of life and mental health indicators, adherence, social support, and disclosure stress, efficacy, readiness, and completion). The intervention will be compared to treatment as usual, with baseline (0 weeks), immediate post-intervention (4 weeks), and 12-week follow-up (16 weeks) assessments.
