Filter by:The purpose of this study is to understand if taking an antibiotic called doxycycline by mouth as soon as possible after sexual contact without a condom can reduce the risk of sexually transmitted infections (STIs), including gonorrhea, chlamydia and syphilis. The study will also look at the safety of doxycycline PEP and the impact that PEP may have on the bacteria that cause STIs as well as on bacteria that normally live on the body. While doxycycline is approved by the Food and Drug Administration (FDA), taking doxycycline immediately after sexual contact to prevent infection is investigational and is not approved by the FDA for this use. Participants will take part in the study for 1 year.
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.
The study involves a randomized placebo controlled trial that aims to assess if a mouthwash (Listerine cool mint, LCM) is able to reduce the cumulative incidence of gonorrhoea (Ng), chlamydia (Ct) and syphilis in men who have sex with men and receiving preexposure prophylaxis (PrEP) at the Institute of Tropical Medicine (ITM).
The purpose of this research study is to compare two specimen collection techniques (vaginal vs. endocervical swab) to screen for sexually transmitted infections in pregnant women. Either a physician or the patient may collect the vaginal specimen; the physician will collect the endocervical specimen during a standard-of-care pelvic exam. Each technique utilizes a specialized swab for specimen collection. We will used the Hologic Aptima C. trachomatis and N. gonorrhoeae detection assay to analyze both specimens. We hypothesize that the results from the physician-collected vaginal specimen will have equivalent outcomes those from the physician-collected endocervical specimen. If the techniques are equivalent for detecting infection, there may be an opportunity for cost saving and increased patient satisfaction with the vaginal technique, especially using patient-collected vaginal specimen collection.
This proposed study is to test whether Health Check-up for Expectant Moms (HCEM), a computer-delivered screening and brief intervention (SBI) that simultaneously targets sexually transmitted infection (STI) risk and alcohol/drug use during pregnancy, reduces antenatal and postpartum risk more than an attention, time, and information matched control condition among pregnant women seeking prenatal care.
