Filter by:Syphilis is a sexually transmitted infection (STI) disproportionately affecting gay, bisexual and other men who have sex with men (gbMSM), with the potential for significant sequelae - particularly in those who are Human Immunodeficiency Virus (HIV)-positive. Rising rates of this STI have prompted a search for novel prevention solutions. A recent pilot study of daily doxycycline prophylaxis demonstrated promise as a novel STI prevention tool. This innovative approach to STI prevention has solid clinical precedent, both from the HIV pre-exposure prophylaxis (PrEP) literature, as well as doxycycline's use as prophylaxis for other infections. The overarching goal of this project is to determine whether the daily use of doxycycline is an efficacious and acceptable intervention for syphilis prevention in high-risk, HIV-positive gbMSM.
UCSF is conducting an evaluation of a demonstration project. The aims of the CRUSH-PrEP for Women project are to integrate the delivery of a comprehensive PrEP package for HIV-negative at-risk women into primary care settings. The delivery of the PrEP package will leverage the well regarded reputation of the LifeLong primary care clinicians to provide a highly effective combination HIV prevention strategy including; PrEP, post-exposure prophylaxis (nPEP), repeat HIV and STI testing, treatment of sexually transmitted infections. Counselling for for sexual health promotion and services specifically designed for vulnerable women such as staying free of violence and domestic abuse will be offered as an integrated part of this package. UCSF will conduct evaluation activities only. The investigators expect that UCSF will enroll 50 participants in the evaluation assessments across the 15 months of data collection. Evaluation cohort participants will provide quantitative data to evaluate the linkage and engagement in care among clinic attendees as well as the uptake and use of Pre-Exposure Prophylaxis.
This randomized clinical trial is an adolescent focused implementation science study directed at improved social support and prevention of both HIV/STI's and subsequent unplanned pregnancies. The study population is pregnant adolescents who are attending antenatal care in Kampala, Uganda The acceptability and effectiveness of two enhanced peer lead, reproductive health promotion interventions compared to routine health care will be studied. The study participants will be individually randomized to one of three arms.
The purpose of this study is to develop and pilot test recruitment methods for a future study of prevention of sexually transmitted infections (STI), including the human immunodeficiency virus (HIV), among Black adolescent boys through sexual health education by their fathers.
The investigators aim to assess the efficacy of a multi-component intervention on condom use and sexually transmitted infection (STIs) in female entertainment workers and men frequenting entertainment establishments (EEs), using a quasi-experimental design. Joo Chiat and Golden Mile Complex will be selected purposively as control cluster sites (n=220) with follow-up of entertainment workers at 6 weeks. The same sites will be used as intervention sites after a 3-months 'wash out' period. Self-reported condom use, vaginal swab samples for polymerase chain reaction (PCR) for cervical gonorrhoea and chlamydia infections, and throat swabs for culture for pharyngeal gonorrhoea will be assessed. Clark Quay will be the intervention venue for the heterosexual men while Tanjong Pagar will be the equivalent control site. Using time location sampling, cross-sectional samples of men patronising these establishments will be assessed on self-reported condom use at baseline (n=600) and 6 months after the intervention (n=400) in both intervention and control groups.
The aim of this study is to determine whether a Strengthening our Vows (SOV) intervention will reduce HIV exposures from concurrent partnership (CP) when compared to the control Good Health Package Plus (GHPP), in addition to couples' voluntary HIV counseling and testing (CVCT), among concordant HIV-negative couples living in Zambia.
Indigenous youth are disproportionately represented in new HIV infection rates in Canada. Limited studies have evaluated longitudinal effects of arts-based approaches to HIV prevention with youth. The authors present a rationale and study protocol for an arts-based HIV and sexually transmitted infections (STI) prevention intervention with Northern and Indigenous youth in the Northwest Territories (NWT), Canada. This is a multi-centre non-randomised cohort pilot study using a pre-test/post-test design with a 12-month follow-up. The target population is Northern and Indigenous youth in eighteen communities in the NWT. The aim is to recruit 150 youth using venue-based sampling at secondary schools. Participants will be involved in an arts-based intervention, Fostering Open eXpression among Youth (FOXY). Participants will complete a pre-test, post-test survey directly following the intervention, and a 12-month follow up.
Despite many years of research, controversy persists as to whether hormonal contraception promotes HIV acquisition. A number of observational studies on depot medroxyprogesterone acetate (DMPA) injection showed an increase in HIV risk and no evidence of increased risk with oral contraceptive pills. There are no human studies currently published on the impact of the levonorgestrel intrauterine device (LNG IUD) on HIV transmission risk and minimal data on the effects of the etonogestrel subdermal implant (ESI) on risk of HIV acquisition. Establishing whether any of these highly effective contraceptives increases the risk of HIV infection would have far-reaching public health implications, particularly in areas of high HIV prevalence such as sub-Saharan Africa, where injectable contraception accounts for nearly half of contraceptive use. Perturbations in the normal vaginal microbiota, or community of microorganisms inhabiting the vaginal body niche, have long been known to affect the risk of transmission of HIV. Studies have shown altered vaginal microbiota with DMPA injection and preserved vaginal microbiota with the LNG IUD, but no studies have compared these methods head-to-head or used culture-independent sequencing methodology. The investigators propose a prospective pilot study to evaluate the impact of different long-acting progestin contraceptive formulations on the vaginal microbiome. Specifically, the investigators aim to identify and compare metagenomics profiles associated with DMPA, LNG IUD, and ESI contraceptive use by community analysis of vaginal swab samples from women collected longitudinally after contraceptive method initiation. The investigators hypothesize that DMPA will increase community diversity in the vaginal microbiota, whereas the LNG IUD and ESI will not affect the balance of microorganisms in the vagina. Women who are planning to initiate DMPA, LNG IUD, and ESI contraception as well as controls not seeking contraception will be recruited for the study from Boston Medical Center (BMC), a tertiary care center with a racially and socioeconomically diverse patient population. Women will have longitudinal follow-up with self-sampling of the vagina for sexually transmitted infection testing and metagenomics analysis at method initiation, 2-3 months, and 6 months. Establishing the safest long-acting progestin contraceptive alternative will promote effective contraception use and lower rates of HIV acquisition worldwide.
Rectal and genital sampling in HIV prevention trials permits assessments at the site of HIV entry. Yet the safety and acceptability of circumcision and sigmoidoscopy (and associated abstinence recommendations) are unknown in uncircumcised men who have sex with men (MSM) at high risk of HIV infection. The purpose of this study is to evaluate the feasibility of methods for assessing baseline characteristics of the mucosa of MSM at risk of HIV infection in Lima, Peru.
The purpose of this study is to determine the impact Pono Choices has among youth for teen pregnancy and STI prevention measures such as: initiation of sexual activity; engagement in high risk sexual behaviors; knowledge of pregnancy and STI prevention; attitudes toward healthy sexual behaviors; skills in managing relationships and choices; and intentions about future sexual activity.
