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.
The purpose of this study is to evaluate the impact of the Wise Guys program on the delaying sexual initiation on adolescent males in Eastern Iowa.
The purpose of this project is to explore women's thoughts, opinions, and ideas about vaginal products. The investigators will ask women to help design the best strategy for applying a vaginal product using a specific kind of applicator. The investigators want to identify designs that women think would be easy to prepare and insert. Women's thoughts and opinions will help researchers develop new products called microbicides that may protect against HIV and other sexually transmitted diseases, that are easy to use, and that will be acceptable to women who use them. If researchers can make products that are easy to use and that women like to use, the products will be used more often, and more infections will be prevented. Women who enroll in the project will either participate in a focus group with approximately 3-7 other women or a one-on-one cognitive interview. All participants will complete a brief questionnaire. Some women may enroll in both stages. Each focus group will take approximately 1.5-2.5 hours. Group leaders will talk to women about their experiences using vaginal products and will provide participants with study products to look at and touch. All participants will be asked to come up with ideas of how to make the products easy to use and acceptable to women who use them. Group leaders will encourage discussion about the different designs. After this, group leaders will talk about a specific type of microbicide and ask women about their opinions. In particular, researchers and participants will talk about the language that would be best understood by women who would use these products or be in studies to evaluate them. Each cognitive interview will take approximately 1.5-2.5 hours. Each participant will be asked about different product designs and application instructions, and will be asked her thoughts, opinions, and potential concerns about each. She will also evaluate sample language that will be used to help women understand the products and how to use them.
The HIV/AIDS epidemic is a major concern in many countries. The epidemic is especially acute in Lesotho where roughly one quarter of the population is infected by HIV/AIDS. In Lesotho, and elsewhere, new innovative approaches to induce safer sexual behavior have been desperately called for, particularly in view of the limited impact that existing prevention schemes have had on the trajectory of the HIV/AIDS epidemic. One of the key questions is to understand why individuals get involved in short-term risky sexual behavior when the potential long-term cost of becoming HIV infected is so high? A follow-up question is what replicable and feasible interventions can affect this trade-off between short and long run returns? The primary aim of this study is to evaluate whether the use of short-term financial incentives can affect this trade-off, thereby influencing young individuals' decisions with respect to sexual and reproductive health behavior, and thus in the end reduce HIV incidence rates. The investigators will study this question using a sample of population attending served by New Start Voluntary Counseling and Testing (VCT) sites that a local NGO, Population Service International (PSI), has already implemented in Lesotho. The investigators propose to conduct a randomized controlled trial to test whether adding a financial incentive to remain STI-negative in the form of a lottery can promote safer sexual activity. The lotteries will work as follows: if the individual is tested negative on a set of curable STIs, she will get a lottery ticket with the chance to win a "big" prize. If she is tested positive, she will receive free treatment, but no lottery ticket. If an individual who tested positive is cured, she can come back in the lottery system and get a later chance to win the lottery ticket if she remains STI-negative. The outcome will be to measure the impact of financial incentives on HIV incidence after two years. The results of this research project will be disseminated through academic and non-academic conferences, workshops, publications in academic journals, and also in policy journals with the aim to reach out to policy makers outside the research community.
The Community Youth Development Study is an experimental test of the Communities That Care (CTC) prevention planning system. It has been designed to find out if communities that were trained to use the CTC system improved public health by reducing rates of adolescent drug use, delinquency, violence, and risky sexual behavior when compared to communities that did not use this approach. The primary purpose of the current continuation study is to investigate whether CTC has long-term effects on substance use, antisocial behavior, and violence, as well as secondary effects on educational attainment, mental health, and sexual risk behavior in young adults at ages 26 and 28. The continuation study also examines (a) how the interaction of social, normative, and legal marijuana contexts creates variation in the permissiveness of individuals' marijuana environments from late childhood to young adulthood and (b) whether, when, and for whom permissive marijuana environments increase marijuana and ATOD use and misuse from age 11 to 28 and interfere with the adoption of adult roles.
The purpose of this study is to examine whether treatment of pregnant Malawian women with repeated doses of sulfadoxine-pyrimethamine and azithromycin antibiotics will prevent preterm deliveries and result in other health benefits both for the mother and the foetus/newborn.
This randomized controlled trial conducted in Rakai District, Uganda, has enrolled 997 HIV positive men and 500 men who declined to learn HIV results (regardless of HIV status). The hypotheses are that male circumcision will be acceptable to and safe in both groups and will reduce the rates of STD acquisition in both groups and of HIV acquisition in HIV-negative men. Enrollment was ended on Dec 12, 2006, following an interim Data Monitoring and Safety Board (DSMB) review of a closed report. At that time the DSMB determined that futility with respect to the female HIV outcome. There was an non-significantly higher rate of HIV acquisition in women partners of HIV+ men in couples who had resumed sex prior to certified post-surgical wound healing. The data indicated significant reductions (~50%) in GUD symptoms among circumcised HIV+ men. The DSMB recommended: 1) that men and women should continue to be followed in complete two year follow up on all, 2) that circumcision for remaining HIV+ intervention arm men and for control arm men who had completed their 2 year follow should continue, contingent on a) revision of the study protocol to add additional post-surgical visits to assess wound healing, b) protocol revision to further strengthen education for both male and female partners on the need to postpone sex until certified wound healing, and c) approval of the revised protocol by the IRBs in both the US and Uganda. 3) An additional follow up visit for women be instituted at 18 months after enrollment. Protocol revision and IRB approvals have been finalized in June, 2007. The study has also enrolled and is following 3,700 women sexual partners of men enrolled in this study and in a complementary National Institutes of Health (NIH) funded study (U1 AI51171 which is separately registered). The hypotheses are that male circumcision will be acceptable to and safe in women partners, and will reduce the women's acquisition of HIV and STDs such as herpes simplex virus-2 (HSV-2) and human papillomavirus (HPV).
This study will evaluate the effect of easy access to emergency contraceptive pills (ECPs) on the rates of pregnancy and sexually transmitted infections (STIs).
