Filter by:This cohort study plans to investigate associations between the presence of multiple lower genital tract microorganisms in pregnancy and gestational age at birth. The study enrols pregnant women at one public health care facility in East London, South Africa. At enrolment and 30-34 weeks of pregnancy, participants provide swabs for testing for sexually transmitted infections, vaginal yeasts and genital mycoplasmas; for microscopy and Nugent scoring; and for 16S ribosomal ribonucleic acid gene sequencing and quantification. The primary outcome is gestational age at birth. Statistical analyses include: regression modelling to explore associations between specific microorganisms (including microbiota) and gestational age at birth; construction of an index of vaginal inflammation, using data about microorganism load and inflammatory potential; classification and regression tree analysis to examine which combinations of microorganisms contribute to earlier gestational age at birth.
This couples-based, digital health intervention project is serostatus neutral and seeks to determine efficacy for: a) use and adherence to evidence-based HIV/STI prevention-care strategies; b) creation and adherence to a tailored prevention-care plan; c) creation and adherence to a tailored sexual agreement; and d) improvements in other relationship dynamics among male couples who are in a relationship (defined as greater than 3 months or more).
This study will test the effectiveness, implementation outcomes, and cost effectiveness of a community-tailored, harm reduction kiosk in reducing HIV, hepatitis C, and overdose risk behavior in rural Appalachia. The proposed project will take place in two counties in Appalachian Kentucky, an epicenter for the intertwined national crises of injection drug use, overdoses, and hepatitis C.
The aim of this first time in human proof of concept (FTiH-PoC) study is to evaluate safety and reactogenicity, to demonstrate efficacy and to explore immunogenicity of GlaxoSmithKline's (GSK) Neisseria gonorrhoeae generalized modules for membrane antigens (GMMA) (NgG) investigational vaccine compared to placebo (saline).
A prospective interventional study to evaluate a strategy of point-of-care testing for sexually transmitted infections including chlamydia, gonorrhoea, trichomoniasis, syphilis, and Hepatitis B with comprehensive case management including partner notification in antenatal settings in Harare province, Zimbabwe.
To achieve an AIDS-free generation, there is a critical need for programs which go beyond individual-level behavior change to reduce HIV and STI infections among adolescent girls and young women in sub-Saharan Africa. Informed, Motivated, Aware, and Responsible Adolescents and Adults (IMARA) is an evidence-based HIV-prevention intervention for adolescent girls and young women (AGYW) and their female caregivers, which has been adapted for a South African audience. The study will test whether AGYW receiving IMARA will have fewer sexually-transmitted infections (STI) and greater acceptance of HIV testing and counseling (HTC) and pre-exposure prophylaxis (PrEP) at 6-month follow-up compared to AGYW assigned to the health-promotion control intervention.
This project seeks to develop and test the acceptability, appropriateness and feasibility of uTECH, a novel social media "big data" machine learning intervention for HIV-negative substance-using sexual and gender minority people who have sex with men that aims to reduce HIV transmission risk by integrating biomedical and behavioral risk reduction strategies, including pre-exposure prophylaxis (PrEP) for HIV prevention and medication assisted treatment (MAT) for substance use harm reduction
The current study extends the study team's earlier efforts described in ClinicalTrail ID#: NCT04070287 and NCT03874663. The I-TEST (Innovative Tools to Expand Youth-friendly HIV Self-Testing) study known locally as the 4 Youth by Youth project, sought to develop and evaluate novel youth-friendly HIVST services in Nigeria using open challenges and apprenticeship training informed by a participatory learning collaborative model. The study thus aims to reach young Nigerians that remain undiagnosed for HIV and to facilitate linkage and retention in preventive services (includes STI testing/treatment, PrEP referral, condom use).
Oral pre-exposure prophylaxis (PrEP) is a recommended component of combination HIV prevention and its availability is rising through demonstration projects and full-scale national programs. In sub-Saharan Africa, young women are a priority population for HIV prevention and targeted to initiate PrEP, given their high HIV incidence rates and promising success from a strategy that can be used without the engagement of male partners. A key question in the field is whether young women using PrEP have ongoing HIV risk and adhere to PrEP sufficiently to have protection from HIV when they have condomless sex with HIV-infected partners. The only true way to know whether a heterosexual woman is sexually exposed to HIV or has a partner with high HIV risk is to test for HIV and STIs in her male partner(s) and quantify HIV viral levels, if any are detected. Yet engaging men in clinic-based HIV testing is challenging. More recent efforts have focused on using HIV self-testing kits to respond to demands on men's time and reluctance to seeking preventive healthcare. The availability of PrEP also provides a new incentive for men to test. By leveraging an ongoing study of bone health with concurrent use of PrEP and injectable DMPA (often known as Depo Provera® or depot medroxyprogesterone acetate), we have opportunity to engage a new cohort of young men and objectively measure HIV and common STIs in these young men and link the results to women's use of PrEP. The primary objective of this study is to determine whether young women's adherence to PrEP aligns with the HIV status and risk of their male partners. To address its primary objectives, this study will leverage: 1) an ongoing study among young women and 2) a novel cohort of young men who are current sexual partners of the young women in the ongoing study to objectively measure PrEP use, HIV, and HIV factors related to HIV risk. This study will provide a framework for understanding how and when young women and men decide to take PrEP, estimate the proportion of women that are benefitting from HIV protection when they have male partners with or at high risk of acquiring HIV, and provide a novel opportunity to engage young men in PrEP delivery and as supporters of women's PrEP use.
The study ANRS 174 Doxyvac is a clinical trial that will use Combined Prevention of Sexually Transmitted Infections (STIs) in Men Who Have Sex with Men and using oral TDF/FTC for HIV Pre-Exposure Prophylaxis (PrEP) and vaccination with Bexsero.
