Filter by:This study seeks to implement a sexual health promotion intervention for male sex workers in Hanoi and Ho Chi Minh City, Vietnam. The study hypothesis is that this intervention will increase testing, treatment and vaccination for sexually transmitted infections, including intentions of participants to engage in these services beyond the conclusion of the intervention. At the community level, the study hypothesis is that male sex workers will be more aware of sexual health care and more likely to access these services in the future.
The purpose of this study is to validate Xpert CT/NG for the detection of CT and GC in rectal samples as part of the PA DOH and CLIA requirements. The evaluation of samples obtained from the pharynx is exploratory and will provide new information on the frequency of pharyngeal infection due to CT and GC. A secondary objective will be to evaluate the prevalence of Trichomonas vaginalis in vaginal and rectal samples using both the Xpert system and AC2 to assess whether women positive for this pathogen rectally usually or always have vaginal infection due to this pathogen. The investigators hypothesis is that real-time PCR (polymerase chain reaction) amplification testing with the Cepheid Xpert CT/NG will have greater sensitivity than culture in detecting Neisseria gonorrhoeae in rectal samples. The investigators also hypothesize that Xpert CT/NG will be equivalent to the Gen-Probe APTIMA Combo2 (AC2) in detecting Chlamydia trachomatis and Neisseria gonorrhoeae in rectal samples.
To evaluate the illumigene Chlamydia and illumigene Gonorrhea assays, using the illumipro-10, with male urine, female urine, physician-collected (medical professional) endocervical swabs and self-collected vaginal swabs taken from symptomatic and asymptomatic patient populations.
This study will estimate the rates of asymptomatic Chlamydia and/or Gonorrhea in the oropharynx, rectum and urethra (urine) of HIV infected men who have sex with men at a specialty care center and compare it to the rates in Douglas County, using nucleic acid amplification tests.
Young men who have sex with men (YMSM) account for almost 70% of HIV diagnoses among all young people in the U.S. and are alone in facing an increasing rate of infections. Because YMSM are less likely to receive relevant sexual health education in traditional settings (e.g. schools, community), the Internet is a unique route of reaching and helping YMSM. The purpose of this study is to compare two different versions of an online HIV prevention program for YMSM. The study is being conducted by researchers at Northwestern University in Chicago, Hunter College in New York City, and Emory University in Atlanta. A total of 900 YMSM will be enrolled into this study from the clinics of community partners in Chicago, New York, and Atlanta. Participants will be randomly assigned to one of two versions of the program. Some topics in the program include HIV facts and myths, sexually transmitted infections (STIs), and condom use. All participants, regardless of the program version they receive, will also take at-home urine and rectal tests for the STIs chlamydia and gonorrhea. After completing the program, participants will be contacted three more times over the course of a year for follow-up sessions and surveys. The research team hypothesizes that the YMSM-specific prevention program will lead to a significant reduction in the frequency of unprotected anal sex acts and new STI infections compared to the HIV knowledge program that is for a general audience. The YMSM-specific program will also lead to improvements in secondary knowledge, motivation, and skills outcomes. In order for the research team to measure the effectiveness of the YMSM-specific prevention program and determine if the study hypothesis is correct, participants will be asked questions about themselves, including questions about their sexual orientation, sexual experiences, health practices, including drug use, health knowledge, and questions about their feelings and emotions. Based on this information, the research team hopes to later change, improve, or expand the program to better address the needs of YMSM.
Expedited Partner Therapy (EPT) has been shown to reduce rates of persistent or recurrent gonorrhea and chlamydia infection in heterosexual patients, but has not been evaluated for use among men who have sex with men (MSM). CDC guidelines support the use of EPT for partner management with heterosexual patients, but note the absence of evidence necessary to make an equivalent recommendation for the use of EPT with MSM. Randomized clinical trials to assess the impact of EPT on partner notification, treatment, and STI re-infection among MSM are critical to the development of evidence-based partner management guidelines. Recent data from urban Peru has identified prevalences of rectal and pharyngeal gonorrhea and chlamydia ranging from 5-20%. The elevated burden of disease among MSM in Peru suggests that frequent transmission of undiagnosed gonorrhea and chlamydia through MSM sexual networks may be a factor contributing to the persistently high incidence of HIV infection among MSM in the region. The investigators propose a pilot evaluation of the effect of EPT on partner notification and treatment among MSM in Peru diagnosed with gonorrhea or chlamydia at any anatomic site. Specific Aim 1: To explore the social norms and structural factors influencing partner notification and treatment among MSM in Peru. Specific Aim 2: To determine the effect of EPT on anticipated and actual partner notification among MSM diagnosed with gonorrhea or chlamydia infection. Specific Aim 3: To develop preliminary data on rates of gonococcal and chlamydial re-infection among MSM randomized to receive EPT compared with standard partner notification counseling. The proposed study will provide pilot data on the use of EPT with MSM diagnosed with gonorrhea or chlamydia and form the basis for a subsequent Phase III clinical trial of EPT as an STI control method among MSM in Latin America.
The purpose of this study is to determine if an Audio-enhanced Computer-Assisted Self-Interview (ACASI) will lead to increase testing for sexually transmitted infections in youth visiting a pediatric ED
This study randomizes St. Louis men to home-based STD screening or clinic-based STD screening. Home-based screening will be completed through the mail and clinic-based screening in a local clinical setting. We hypothesize that men randomized to home-based screening will be more likely to complete screening.
Though partner notification is mandatory to perform of Chlamydia trachomatis infected individuals in Sweden, there was a 10-15% annually increase of reported cases between 1997 and 2007 indicating that partner notification may not be effective in preventing transmission. The investigators wanted to determine whether there was any difference in time between home-sampling and clinical testing as a tool of partner notification measured from eliciting of partners to date of testing.
This project seeks to determine the personal and organizational conditions that are most conducive to the widespread adoption by community-based organizations (CBOs) of effective programs for reducing the spread of HIV and other sexually transmitted infections (STIs). Taking a brief, single-session counseling program (called "Mujer Segura") that has been proven effective in reducing HIV and STIs in female sex workers who work in Mexican cities along the U.S. border, this project will study the implementation of the program in CBOs in 12 additional cities throughout Mexico to determine how best to ensure that the program remains true to the original model and retains its effectiveness. Mexico has been chosen because HIV is a global problem that respects no international borders, and because HIV prevention programs that can be implemented in settings with limited resources are urgently needed in many parts of the world.
