Filter by: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.
To evaluate the efficacy of the adapted program a randomized controlled trial enrolling 620 eligible African American men who have sex with men (MSM) will be conducted. Men in the treatment condition will be compared to men receiving the control condition comprised of standard of care counseling from the clinic plus a free bag of condoms and water-based lubricants. This two-arm trial will test four hypotheses: Aim: To test the efficacy of a brief, clinic-based and theory-guided, intervention designed to reduce STD incidence and risk of HIV acquisition/transmission among young African American men (15-29 years old) having sex with men and presenting for STD testing. H1. Men randomized to receive the intervention will have a lower incidence rate of laboratory-confirmed STDs at each of three follow-up assessments compared to those receiving the control condition. H2. Men randomized to receive the intervention will report significantly fewer acts of unprotected penetrative sex (penile-vaginal or penile-anal) between follow-up assessments compared to those receiving the control condition. H3. Men randomized to receive the intervention will report having significantly fewer unprotected penetrative sex partners (for penile-vaginal or penile-anal sex) between follow-up assessments compared to those receiving the control condition. H4. Men randomized to receive the intervention will report having significantly fewer negative experiences with condom use between follow-up assessments compared to those receiving the control condition. H5. Men randomized to receive the intervention will demonstrate significantly greater improvement in condom application skills, throughout the 12-month study, compared to those receiving the control condition.
Mass antimicrobial administrations have been remarkably successful in reducing the prevalence of the ocular strains of Chlamydia that cause trachoma. Repeated distributions progressively lower the prevalence of infection, and in some cases may even result in local elimination. Mass treatments cannot be continued forever, due to concerns about cost and antibiotic resistance. The hope has been that other measures such as latrine construction and hygiene programs would prevent infection from returning. Unfortunately, no non-antibiotic measure has yet demonstrated an effect on infection. 1. We hypothesize that Chlamydial infection will return to communities when treatment ends. 2. We hypothesize that infection will be completely eliminated in all communities treated for seven years. 3. We hypothesize that identifying and treating clinically active cases among preschool aged children will delay or even prevent reemergence at a far lower cost than mass treatment of all individuals.
Project Aware introduces a sexually transmitted infection (STI) screening model for sexually experienced adolescents aged 14 to 21 in a large, inner-city Emergency Department (ED) in the Bronx, N.Y. Project Aware will scaffold routine, rapid testing and counseling for Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (GC) onto an existing, successful, ED-based HIV testing and counseling program, Project BRIEF. Project Aware will educate and motivate youth to use condoms with the aid of a theory-based, youth-friendly multimedia behavioral intervention proven to be effective during the investigator's K23 training. Through Project Aware, the investigators propose to change the paradigm of STI testing. Whereas a view of "HIV exceptionalism" has persisted in U.S. health policies on STI testing, the investigators propose a comprehensive approach, in which efforts to identify, treat, and prevent multiple STIs coalesce in one program. The research study has two phases. In the production phase, new STI material will be added to the multimedia intervention currently used for HIV education. In the evaluation phase, a randomized controlled trial (RCT) will be conducted to assess the effectiveness of Project Aware in identifying, treating, and preventing new STI infections among high-risk adolescents. The RCT is designed to test the incremental effectiveness of three STI prevention methods: (1) HIV testing and counseling (T&C), (2) HIV T&C and STI testing, and (3) HIV/STI Testing plus a point-of-service risk reduction video that incorporates both HIV and STI counseling and education. The study is powered to examine three STI prevention outcomes: (1) the number of STI infections identified and treated successfully at baseline; (2) the number of new STI infections over the 12 months following study entry, identified by (a) performing STI testing at each follow-up assessment; and (b) obtaining anonymized rate data on STIs reported to the New York City Department of Health; (3) condom use behavior. 600 youth aged 14-21 will be enrolled in the RCT. Youth will be approached in the ED waiting room and recruited by Public Health Advocates. All will complete a survey to screen for eligibility; eligible youth will complete the baseline measures and be randomized. The follow-up data points and measures will be followed at 4, 8 and 12 months (4 time points) and STI testing will be included.
This study randomizes women using long-acting reversible methods of contraception to home-based STD screening through the mail compared to screening available in a clinical setting. We hypothesize that women randomized to home-based screening will be more likely to complete screening.
Multicenter clinical study to test a new qualitative in vitro nucleic acid amplification assay based on kPCR technology. The assay is intended for the diagnosis of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (GC).
The primary objective is to prospectively follow 200 women with or at risk of cervicitis to determine the chlamydia-specific cellular responses that correlate with protection against incident infection. The hypothesis is that a positive IFN-y response by peripheral CD4+ T cells responding to stimulation with HSP60 will be significantly associated with protection from incident C. trachomatis infection.
The purpose of this study is to conduct a quality improvement intervention to improve the ability of health care providers to deliver an important preventive health service (CT screening) in order to meet the goal of universal CT screening for young women age 25 or younger as recommended by the CDC and virtually all major health organizations. This novel approach utilizes a bilingual (English-Spanish) computer kiosk module to deliver education about CT and allow patients to request a CT screening test. This module should significantly increase CT screening among at risk women (18-25yo) attending urgent care clinics and emergency departments.
