Filter by:PrEP (pre-exposure prophylaxis) is an effective prevention strategy in which HIV-negative individuals take antiretroviral drugs (tenofovir disoproxil fumarate and emtricitabine - TDF/FTC) to reduce HIV acquisition. Clinical studies have shown that the TDF/FTC combination protects MSM and transgender women against HIV infection. According to the PROUD study, PrEP can decrease the risk of HIV infection among MSM by 86% (90% CI 64-96). The international community recognizes that PrEP can be an additional tool in the framework of a combination prevention package for those most at risk of contracting HIV. Data on HIV incidence among MSM and trans women are largely unknown. In Brazil, Mexico and Peru, data on the incidence of HIV among MSM and trans women are very scarce, limited to small cross-sectional studies.Current methods used to determine HIV-1 incidence have many limitations. These methods include mathematical modeling, retrospective calculations of AIDS case reports, age-based prevalence determinations, and prevalence determinations with multiple rounds of longitudinal surveys to estimate HIV incidence, which require numerous assumptions and inputs and can pose additional challenges in the era of expansion of antiretroviral therapy (ART) and increased survival of HIV-1 infected individuals. On the other hand, prospective longitudinal cohort studies of high-risk individuals can be used to estimate incidence; however, they are often labor-intensive, complex, very expensive, difficult to implement in most countries, and have recruitment biases. Laboratory methods can be unbiased and do not require complicated assumptions and case-by-case weighting. The cross-sectional use of Recent HIV Infection Tests (TRIs) based on biomarkers offers, in principle, accessible, reliable and low risk of bias options for estimating incidence.
Young Thai men who have sex with men (YMSM) are at high risk for HIV. However, the Thailand National HIV Strategy does not adequately cover HIV prevention for YMSM using specific methods relevant to them, and instead uses a one-size-fits all approach. Partnering with the Thailand Ministry of Public Health (MOPH), the proposed study seeks to finalize, implement and evaluate a multicomponent, multi-level, community mobilization, combination intervention (HUG-M+) to address the entire Continuum of Prevention and Care. The investigators propose to test the efficacy of this approach by conducting research in two Northeastern Thai cities, one randomized to the intervention condition, which will receive HUG-M+ and the other to the control condition, where standard of care will be provided. If HUG-M+ is found to be efficacious, it might be scaled up, with the support of the MOPH, to other regions in Thailand, elsewhere in Asia and the US.

High School FLASH is a 15-session comprehensive sexual health curriculum designed for classroom settings in grades 9 to 12. The basis of High School FLASH is a public health approach to behavior change. The primary strategy used in the FLASH curriculum for preventing teen pregnancy, sexually transmitted diseases (STDs), and sexual violence is to address student behaviors and attitudes. To this end, FLASH uses a harm reduction and behavior change framework, implements best practices as outlined in the research on effective programs, addresses risk and protective factors for program goals, and rests on the theory of planned behavior. The instructional approach of High School FLASH employs key concepts in every lesson, which enables teachers to hone in on the risk and protective factors outlined in the curriculum logic model. The curriculum covers the following topics: reproductive system, pregnancy, sexual orientation and gender identity, healthy relationships, coercion and consent, online safety, abstinence, birth control, preventing human immunodeficiency virus (HIV) and other STDs, condoms, STD testing, communicating and decision making, and improving school health. The curriculum aligns with national health education standards.
Epidemiology of Sexually Transmitted Diseases (STDs) in women admitted in a Family Planning for a termination of pregnancy is poorly defined currently in France. Only one bi-centre study (Bourgeois-Nicolaos, 2015), performed in two Family Planning suburban centres located within University Hospital (Assistance Publique-Hôpitaux de Paris), found high prevalence: C. trachomatis 15.1%, N. gonorrhoeae 3.1%. Moreover, heterogeneity can occur between centres. In students in Sweden, 26% had one or several previous STDs, mainly C. trachomatis and Human Papilloma Virus (HPV). Having previously a termination of pregnancy was a risk factor of STDs. Systematic screening for STDs in Women Admitted in Family Planning for a Termination of Pregnancy appears thus a logical strategy.
National guidelines have recommended routine STD screening (chlamydia and gonorrhea) for sexually active young women under the age of 25. Despite these recommendations, many young women are not being screened for STDs, with some estimates that less than 50% of women receiving health care are screened for chlamydia. Untreated STDs can lead to important sequelae to women's reproductive health including pelvic inflammatory disease, infertility and ectopic pregnancy. One of the most important barriers to widespread STD screening is provider failure to recognize an opportunity for STD screening. The goal of this study is to determine whether offering STD screening (chlamydia and gonorrhea) by a non-physician member of the medical practice (who receives an automated alert indicating STD screening should be offered) will be associated with a higher rate of STD screening in young women attending primary care practices compared to usual care (where a physician offers screening with no electronic alert). This study will be performed in UPMC-affiliated primary care practices (Family Practice, Internal Medicine, OB/GYN, Pediatrics). Practices will be assigned to the intervention or usual care. The intervention will be an auto-task in the electronic medical record to the non-physician/NP/PA medical staff (medical assistants, LPNs, RNs) to offer chlamydia and gonorrhea screening via urine or self-collected vaginal sampling, in an opt-out manner, to eligible women. Practices assigned to the usual care group will not have the intervention. STD screening rates (# women undergoing STD screening/# eligible women) will be compared between the to groups (intervention practices and control practices). Results of this study may be important to guide national STD screening recommendations and will address critical barriers to widespread STD screening.
The purpose of this study is to examine the efficacy of a brief culturally appropriate and theory-based parental communication intervention designed to improve parent-adolescent sexual communication and reduce adolescent sexual risk behavior.
Recently human papillomavirus (HPV) has been recognized to cause some oropharyngeal (tonsil) cancer. But very little is known about oral HPV infection and risk factors. This study will evaluate how common oral HPV infection is, what sexual behaviors are associated with risk for infection, and how long infections tend to last.
