INTRODUCTION The prevention of reinfection of sexually transmitted infections (STIs) is highly dependent on the level of risk perception and the subsequent adoption of preventive behaviors. While perceived risk is assumed to be key to adoption of preventive measures, the evidence regarding the predictors of perceived risk to STI reinfection are limited. METHODS This paper is based on a cross ...

maize improvement for high temperature tolerance requires the reliable assessment of parental inbred lines and their combinations. fifteen maize inbred lines were evaluated during 2007 and 2008 in shushtar city (khuzestan province). the inbred lines were planted at two dates: 6 july, to coincide heat stress with pollination time; and 27 july, as normal planting to avoid high temperature during ...

OBJECTIVE To better understand preferences and practices regarding partner notification of sexually transmitted infection (STI) among female, African-American adolescents. METHODS Participants completed a questionnaire and STI testing at baseline. Those diagnosed with Chlamydia or gonorrhea were recruited for a follow-up study, involving another questionnaire and repeat STI testing after thre...

OBJECTIVES To assess HIV and sexually transmitted infection (STI) prevalence and associated risk factors in men who have sex with men (MSM) in two cities in mainland Tanzania. METHODS We conducted respondent-driven sampling of 300 MSM in Dar es Salaam and Tanga. RESULTS In Dar es Salaam, 172 (86%) men (median age 23, IQR 21-28) consented to HIV/STI testing, and 30.2% were HIV seropositive. ...

In the USA, family planning clinics are primary providers of reproductive healthcare to young women and their male partners and have long provided quality sexually transmitted infection (STI) care and prevention. Chlamydia, an easily treatable STI that can lead to serious adverse outcomes if untreated, is the most common bacterial STI in the USA, and annual chlamydia screening is recommended fo...

Pre-Exposure Prophylaxis (PrEP) has shown high efficacy in preventing human immunodeficiency virus (HIV) infection among men who have sex with men (MSM) in several large clinical trials, and more recently in "real world" reports of clinical implementation and a PrEP demonstration project. Those studies also demonstrated high bacterial sexually transmitted infection (STI) incidence and raised th...

BACKGROUND Internet-accessed sexually transmitted infection testing (e-STI testing) is increasingly available as an alternative to testing in clinics. Typically this testing modality enables users to order a test kit from a virtual service (via a website or app), collect their own samples, return test samples to a laboratory, and be notified of their results by short message service (SMS) or te...

BACKGROUND AND OBJECTIVES Partnerships that are discordant by demographic and behavioral characteristics or are concurrent may facilitate transmission of sexually transmitted infections (STIs) by bridging sexual networks. GOAL : The goal of this study was to examine if STI risk within partnerships is associated with discordance and concurrency using the partnership as the unit of analysis. ...
