Filter by:A randomized controlled trial to: 1. To compare both primary (composite quality health indicator (QHI) scores) and secondary (individual HIV/methadone maintenance treatment (MMT)/TB/primary care QHI scores, quality of life, and stigma) outcomes in an anticipated 1,350 people who inject drugs (PWID) receiving MMT from 13 regions (clusters) and 39 clinical settings using a stratified, phase-in, controlled design over 24 months. After stratifying PWIDs based on their current receipt of MMT, they will be randomized to receive MMT in specialty addiction clinics (N=450) or in an ECHO-IC/QI-enhanced primary care clinic with (N=450) or without (N=450) pay for performance (P4P) incentives. 2. Using a multi-level implementation science framework, to examine the contribution of client, clinician and organizational factors that contribute to the comprehensive composite (primary outcome) and individual (secondary) QHI scores.
Background: Tuberculosis (TB) is a health threat for people living with human immunodeficiency virus (HIV). People living with HIV are more likely than others to develop active TB. Also, TB makes HIV progress faster. TB is a leading cause of death among people in the West African country of Liberia. Researchers want to find an effective testing method for latent tuberculosis infection (LTBI) to help people living with HIV in Liberia. Objective: To compare the interferon-gamma release assay (IGRA) and tuberculin skin test (TST) as LTBI screening tests in people living with HIV in Liberia. Eligibility: People ages 18 and older who take part in NIH study #19-I-N014 and are scheduled to have or have had IGRA at a Month 12 HONOR study visit. Design: Participants will be screened with a medical history and physical exam. Their medical records and HONOR study records will be reviewed. Participants will have TST. Purified protein derivative will be placed in the skin of their forearm. They will be observed for adverse reactions for 15 minutes. Between 48 and 72 hours after placement, they will have a second study visit to have the TST read. If they miss this time frame, they can return up to 7 days after placement. If they have a positive test result, they will have a chest x-ray. They will have a third study visit to review the results of the chest x-ray. They will be referred for clinical care if needed. They will take a pregnancy test if needed. Participation will last from 2 days to 6 weeks.
Men in Sub-Saharan Africa are less likely to test for HIV, initiate ART, and more likely to initiate ART at later stages of disease. Two overarching barriers keep HIV-positive men from accessing ART services: 1) Lack of male-friendly services, and 2) harmful gender norms. Home-based ART may improve ART initiation and retention among male partners who test HIV-positive through Index HIV self-testing (HIVST). We will pilot an intervention that provides home-based ART initiation and home-based continuation for 3-months, followed by assisted linkage to facility-based care at 4-months. 470 participants will be enrolled [209 females, 261 males]
Men in sub-Saharan Africa who test HIV-positive continue to have poor ART initiation and retention outcomes. The proposed project will test a home-based ART intervention for men who are living with HIV compared to facility-based ART. Findings will provide essential information on how to best reach men across the testing and treatment continuum, a critical step to curbing the HIV epidemic.
While HIV prevalence among MSM in India is 10-15 times higher than in the general population (4.3% vs 0.3%), current interventions for Indian MSM have limited reach. In order to reduce the burden of HIV in MSM, innovative, far-reaching prevention and treatment strategies are needed. Guided by the increase access to internet-based social and mobile technologies (SMT) (e.g. SMS, WhatsApp, dating apps) globally and in India, this is a 3-arm parallel, pragmatic randomized controlled trial of community-developed, theory based behavioral intervention (CHALO! 2.0) delivered via WhatsApp (secure SMS application) compared to an Attention-Matched Control, or a Digital Coupon for free HIV testing only control conditions. The primary outcomes are HIV-testing at 6 months (3 months after the end of the intervention) and linkage-to-preventive care (counseling or pre-exposure prophylaxis) at 12 months. The secondary outcomes are the frequency of HIV-testing by 18 months.
The randomized trials in this record will assess effectiveness, fidelity and cost of prevention and treatment interventions for HIV and hypertension with the objective of informing a population-based study of multi-sectored, multi-disease interventions for HIV.
This study will consolidate under one umbrella protocol all NIH studies of the safety and survival of gene-modified lymphocytes in HIV-infected twins. The major purposes of the current study are to: - place subjects from the various identical twin cell transfer/gene therapy studies on a single, more uniform schedule of visits; - examine the long-term safety of apheresis procedures in non-HIV-infected lymphocyte donor twins; - examine the long-term safety of lymphocytes in HIV-infected lymphocyte recipient twins. Identical twins enrolled in NIH protocols 93-I-0110, 94-I-0206, 96-HG-0051, and 97-I-0165 involving the transfer of lymphocytes for the treatment of HIV infection are eligible to continue their research participation under the current protocol, 02-I-0080. Participants will not undergo any additional research procedures in this study. They will continue to take their antiretroviral therapy and will be followed at least once a year, or more often if medically indicated, with a medical history, physical examination and blood tests for routine studies and to determine the number of lymphocytes in the blood. Recipient twins will also have blood levels of gene-modified lymphocytes checked. Recipient twins will have some blood stored for RCR (replication competent retrovirus) testing, should it become necessary. A special virus was used to insert genes into the donated lymphocytes and, although the virus was rendered incapable of growing in the body, a theoretical risk exists that the virus could mix with other viruses and possibly begin growing or reproducing. If a participant subsequently develops medical problems, the stored blood samples can be checked for RCR to see if it may be a cause of the problem.
This is an ancillary study, thus participants will be recruited from participants in the HBS Study. This project acutely assesses the role of the e-cigarettes and vaping on lung health. The proposed work will inform the design of future studies to better understand vaping's health consequences and to test novel interventions to mitigate vaping's contribution to acute and/or chronic lung injury.
The purpose of this study is to conduct a pragmatic, stepped wedge cluster randomized trial in 12 HIV pediatric clinics in Ghana to determine effectiveness, health benefits, cost and implementation to inform scale-up and sustainability of pediatric disclosure.
The purpose of this study is to see if providing participants with pre-exposure prophylaxis (PrEP) medicine right away at the IDEA Exchange will help participants remain in HIV negative.
