Kumara V Nibhanipudi, Kenneth Cody
Background. In all cases of suspected sexually transmitted infections (STIs), it has been routine practice to screen for syphilis with a blood sample. The incidence of syphilis seems to be lower than that of commonly screened STIs. Objective. The objective of our study was to determine whether it is cost-effective to screen for syphilis with serological testing in cases of suspected gonorrhea and chlamydia infections. Hypothesis. Our hypothesis is that it is not cost-effective to screen for syphilis in cases of presumed gonorrhea and chlamydia infections...

The 'Cuidate' programme for adolescents in Spain has proven to be effective for promoting healthy sexuality ( N = 626), but the mechanisms underlying its effects are unknown. This study aimed to identify mediators of the intervention's effects compared to a control group. Participants were students from five areas of Spain, who completed baseline, immediate-posttest, 12-month and 24-month follow-up assessments. Mediation analyses revealed that 'Cuidate' positively affected consistent condom use indirectly through knowledge in serial with the intention to use condoms...

This study examines the effect of condom negotiation strategies on condom use and partner type and substance use before sex as moderators of strategy effectiveness. Women reported their daily sexual behavior during the last month. Withholding sex was more strongly associated with condom use when utilized with a non-casual sex partner. Directly requesting condom use was more strongly and using deceptive reasons to influence condom use was less strongly related to condom use during substance use. Results underscore the importance of understanding the contexts in which condom negotiation strategies are successful in order to improve HIV/sexually transmitted infection prevention efforts among women...

BACKGROUND: Many sexually transmitted disease (STD) clinics offer testing-only "express" visits. We evaluated the express care triage algorithm that is based on a computer-assisted self-interview (CASI) used in the Public Health-Seattle and King County STD Clinic. METHODS: During the analysis period, patients received a clinician evaluation irrespective of triage status. In this cross-sectional study, we compared the algorithm triage status to a disease-focused outcome determined by medical record review...

BACKGROUND: Sustained genital tract inflammation caused by sexually transmitted infections (STIs) is known to increase risk of vaginal human immunodeficiency virus (HIV) infections but, to our knowledge, there are no nonhuman primate studies that have evaluated its link to rectal HIV acquisition. METHODS: Rhesus macaques inoculated with Chlamydia trachomatis (CT) (serovars LGV-L2 and CT-E; n = 7) or saline (n = 7) received up to 20 rectal challenges twice a week of simian/HIV immunodeficiency virus (SHIVSF162p3)...

In contrast to anorectal lymphogranuloma venereum (LGV), few urogenital LGV cases are reported in men who have sex with men. Lymphogranuloma venereum was diagnosed in 0.06% (7/12,174) urine samples, and 0.9% (109/12,174) anorectal samples. Genital-anal transmission seems unlikely the only mode of transmission. Other modes like oral-anal transmission should be considered.

BACKGROUND: Few men are tested for syphilis or human immunodeficiency virus (HIV) during their partner's pregnancy, a high-risk period for HIV and syphilis transmission. Offering home-based rapid testing of syphilis to couples during pregnancy can support prevention efforts to reduce transmission of sexually transmitted diseases and adverse pregnancy outcomes. METHODS: We assessed men's uptake of paired (separate tests, single blood draw) point-of-care syphilis and HIV tests within a randomized controlled trial of pregnant women who received clinic or home partner HIV testing...

BACKGROUND: Childhood maltreatment, particularly sexual abuse, has been found to be associated with sexual risk behaviors later in life. We aimed to evaluate associations between a broad range of childhood traumas and sexual risk behaviors from adolescence into adulthood. METHODS: Using data from Waves I, III and IV of the National Longitudinal Study of Adolescent to Adult Health (Add Health), we used logistic regression to estimate the unadjusted odds ratio (OR) and adjusted OR (AOR) for associations between 9 childhood traumas and a cumulative trauma score and three sexual risk outcomes (multiple partnerships, sex trade involvement, and sexually transmitted infection [STI]) in adolescence, young adulthood, and adulthood...

BACKGROUND: Racial disparities in the burden of sexually transmitted diseases (STDs) have been documented and described for decades. Similarly, methodological issues and limitations in the use of disparity measures to quantify disparities in health have also been well documented. The purpose of this study was to use historic STD surveillance data to illustrate four of the most well-known methodological issues associated with the use of disparity measures. METHODS: We manually searched STD surveillance reports to find examples of racial/ethnic distributions of reported STDs that illustrate key methodological issues in the use of disparity measures...

BACKGROUND: Evolving health priorities and resource constraints mean that countries require data on sexually transmitted infections (STI) trends to inform program planning and resource allocation. METHODS: The Spectrum modeling tool estimated prevalence and incidence of gonorrhea and chlamydia in Morocco's 15- to 49-year-old population, based on prevalence surveys. Incident cases, broken down between symptomatic and asymptomatic, and treated versus untreated, were compared with urethral discharge (UD) case reports, to estimate reporting completeness among treated UD cases...

Sexual reproduction in higher plants consists of several major biological processes which include mega- and micro-gametogenesis, male-female communications, embryogenesis and endosperm development. Male-female communications include male gametophyte-sporophytic tissues (stigma/transmitting tract) interaction and male-female gametophyte communication, during which various signaling pathways are involved.

OBJECTIVES: Adolescents and young adults are at high risk for sexually transmitted infections (STIs). We previously reported an increase in STI testing of adolescents in our ED by obtaining a sexual history using an Audio-enhanced Computer-Assisted Self-Interview (ACASI). We now examine associations among demographics, sexual behaviour, chief complaint and willingness to be tested. METHODS: This was a prospective study conducted in a paediatric ED between April and December 2011...

INTRODUCTION: Gonorrhoea is a common sexually transmitted disease caused by Neisseria gonorrhoeae (Ng) infection. Light microscopy of urogenital smears is used as a simple tool to diagnose urogenital gonorrhoea in many resource-limited settings. We aimed to evaluate the accuracy of light microscopy to diagnose urogenital gonorrhoea as compared with a PCR-based test. METHODS: In 2014, we examined 632 male urethral and 360 endocervical smears in clinic-based and outreach settings in Jakarta, Yogyakarta and Denpasar, Indonesia...

BACKGROUND: Latex condoms for men have been documented to offer high efficacy as both a contraceptive and protection against sexually transmitted diseases. This equally establishes the importance of continued research on female condoms. This study aims to investigate the perceived confidence to use the female condoms amongst undergraduate female students from selected tertiary institutions from Ibadan Southwestern Nigeria. METHODS: The study was a descriptive cross-sectional survey involving 388 female undergraduate students selected through a multistage sampling technique...

BACKGROUND: The sexual stages (gametocytes) of Plasmodium falciparum do not directly contribute to the pathology of malaria but are essential for transmission of the parasite from the human host to the mosquito. Mature gametocytes circulate in infected human blood for several days and their circulation time has been modelled mathematically from data of previous in vivo studies. This is the first time that longevity of gametocytes is studied experimentally in vitro. METHODS: The in vitro longevity of P...

In Chile, sex work takes place covertly in a variety of venues and locations. Formative research using time-location sampling methods is important in order to understand the nature of this diversity. This study used qualitative methods to develop a typology of female sex work in the Metropolitan Region of Santiago, Chile, using semi-structured interviews, focus groups and ethnographic fieldwork during visits to sex work venues. The study identified seven types of venue, which reflect the context and regulatory framework of the country and the structural vulnerabilities that affect female sex workers in Chile...
