Filter by:Primary purpose of the study: to describe sexual behavior of Prep users, whatever mode of intake, ie continuous or on-demand; it has been shown in some studies, an increase of sexual risks in Prep users, and therefore an similar increase of STIs (sexually transmitted diseases); using a self-questionnaire, we'd like to evaluate sexual behavior before, and 6 months after, starting Prep. Secondary purposes: to describe medical characteristics of Prep users (past medical condition, demographic characteristics, vaccinations, kidney function, serological results, urine and anal/pharyngeal swabs), clinical and biological Prep safety, STIs occurrence, and antibiotic prescriptions, continuous or on-demand intake, Prep indication.
A randomized three arm control trial to examine the efficacy of two distinct apps (LYNX and MyChoices) developed for young men who have sex with men (YMSM) compared to standard of care (SOC) information about HIV testing and PrEP (Pre-Exposure Prophylaxis).
The number of infectious agents associated with risks of malignant hematologic diseases is non-negligible and include both viruses and bacteria. The various organisms affect cancer risk either directly by transforming susceptible cells, through chronic antigenic stimulation or by hampering immune function in other ways conducive of cancer development. Suspicion of an infectious cancer origin may arise because of clustering with other conditions (e.g. immune deficiency), specific environments or settings (e.g. geographic locales) or with exposures (e.g. blood transfusions). In this context, relatively few studies have addressed clustering of diseases among spouses to generate hypotheses about the relative contributions of environmental and genetic factors to the risk of individual cancer types. As a prelude to such an exercise aiming specifically at malignant hematologic diseases, we will test an algorithm characterising cohabitation patterns in the Danish population to assess the risk of sexually transmitted diseases in analyses of register data. Such information will also be relevant to current guidelines for blood donor deferral policies. Specifically, because of the so-called precautionary principle all blood donations are extensively tested for infectious agents and transfusion of blood now carries an extremely low risk of transmission of HIV, hepatitis B and C. The residual risk of HIV transmission in Denmark is estimated to 1:10,000,000 transfusions. However, several deferral criteria have existed for years without studies to prove their relevance. Aim: To compare the incidence of both known and suspected sexually transmitted diseases between different cohabitation patterns in the Danish population. Perspectives: The study results can be used to leverage changes in deferral rules in the Danish blood banks to accommodate strong wishes from stakeholders to avoid the perceived discrimination of various minorities. The study can thus have important ethical and political consequences.
This study evaluates a peer intervention with HIV/STI self-testing kits to increase HIV/STI testing and PrEP uptake among Latino immigrant men who have sex with men. Half of participants will receive the "Listos" intervention (peer counseling, PrEP information, and HIV/STI testing kits) and half will receive the active control intervention (peer only group with no HIV/STI testing kits).
AllyQuest (AQ) is a theory-informed smart phone application that supports HIV medication adherence for young men who have sex with men and young transgender women who have sex with men (YMSM/YTW) via behavior change, social support, and game-based mechanics. This study aims to evaluate the feasibility and acceptability of AQ and AQ plus medication adherence counseling in a Sequential Multiple Assignment Randomization Trial.
The aim of this research protocol is to test the efficacy of a self-care intervention through a randomized controlled trial (RCT), for increasing protective sexual health behaviors among youth in the participating Native American community. The investigators will randomize 450 youth and young adults ages 14-26 to the self-care intervention or a control program. Efficacy data will be collected up to 6 months post-intervention. The primary outcome will be uptake of sexually transmitted infection (STI) screening. Secondary outcomes will include: a) sexual risk and protective behaviors; and b) psychosocial assets and resources. The investigators hypothesize the self-care intervention will increase protective behaviors by: i) helping youth gain knowledge of their own sexual health risks, assets and resources; ii) motivating protection of those assets and resources; and iii) encouraging good health practices and making responsible choices.
In response to the increasing rates of HIV/STD infections among women over the age of 50, especially minority women, and in the attempt to reduce HIV/STD risks for over ten million older adult American women who are impacted by gray divorce and at risk for unsafe sex, the investigators will create, test, and commercialize a novel positive psychology-based "SmartWeb" intervention to promote wellbeing, HIV/STD awareness, and safe sex practices among culturally-diverse older divorced or separated women who are dating. This large end-user market for the proposed HIV/STD risk reduction intervention will greatly facilitate commercialization through advertisements, marketing research based on data mining, and in collaboration with manufacturers of condoms, and other large companies offering health products and services to older women.
This randomized control trial (RCT) will assess an innovative demonstration project to improve adolescent sexual and reproductive health among highly mobile and marginalized youth in Fresno County, California. The Digital Initiative for Youth intervention combines existing, in-person, group-based, comprehensive sexual health education with wraparound digital technologies. The technological component was designed by Youth+Tech+Health using a "youth-centered" design approach and the intervention is implemented by Fresno Economic Opportunities Commission (Fresno EOC). The University of California, San Francisco is the external evaluator. The RCT will assess health and behavioral outcomes at three time points (baseline, 4 months, 10 months).
This investigation is designed to evaluate the performance rate of a new natural rubber latex (NRL) male condom.
Developed from a piloted intervention and based on scientific evidence, About Us is an innovative healthy relationships intervention that promotes positive adolescent romantic relationships and use of condoms and highly effective contraceptives if having sex. The program includes 10 lessons (2 that are between 30-45 minutes long 8 that are 50 minutes long) that blend group-based activities with online activities implemented in a small group format with students in grades 9 or 10 who have parental consent and provide assent to take part. The program will be implemented in school-based health centers (SBHCs). Primary research question: 1. Nine months following the end of the program, what is the impact of About Us relative to the standard of care on: 1.1. Rates of vaginal or anal sex without condoms in the past three months? Secondary research questions: 2. Three and nine months following the end of the program, what is the impact of About Us relative to the standard of care on: 2.1. Rates of abstinence from vaginal or anal sex in the past three months? 2.2. Frequency of communicating without abuse? 2.3. Utilization of school-based health center services? 2.4. Rates of behavioral willingness and attitudes toward birth control? Exploratory research questions: 3. Three and nine months following the end of the program, what is the impact of About Us relative to the standard of care on: 3.1. The psychosocial variables stemming from the theoretical framework (e.g., attitudes toward condom and contraceptive use, normative beliefs, perceived self-efficacy to use condoms or have difficult conversations) and enumerated in the logic model. 3.2. Outcomes listed above within key sub-groups including those defined by sex (male/female), race/ethnicity, and exposure to violence; 4. Among those receiving About Us, how do effect sizes for the primary and secondary behavioral outcomes vary by dosage?
