BACKGROUND: The natural course of sexually transmitted infections caused by Chlamydia trachomatis varies between individuals. In addition to parasite and host effects, the vaginal microbiota might play a key role in the outcome of C. trachomatis infections. Interferon-gamma (IFN-γ), known for its anti-chlamydial properties, activates the expression of indoleamine 2,3-dioxygenase (IDO1) in epithelial cells, an enzyme that catabolizes the amino acid L- tryptophan into N-formylkynurenine, depleting the host cell's pool of tryptophan...

BACKGROUND: Despite changing sexual norms and mores generally perceived to be permissive of sexual expression, parents continue to serve as gateways to uptake of reproductive health services and commodities in our cultural settings. However, their support for adolescent uptake of human papilloma virus (HPV) vaccine are not well explored and documented. This study aims to assess parental knowledge and awareness of HPV infection and cervical cancer and their support for HPV vaccination for their adolescent children...

Symptoms of sexually transmitted infections (STIs), whether they are presented for treatment or diagnosis, and how they are received by the clinician where they are presented, may be concomitants of stigma associated with homosexuality in homophobic climates. We analyzed respondent-driven sampling data from a study on 200 young men who have sex with men (MSM) in Dar es Salaam, Tanzania to examine sample prevalence, treatment and clinician response to 10 symptoms potentially associated with STIs. Survey measures included 10 self-reported STI symptoms, further specified according to location (genital, anal, oral), further specified according to place of diagnosis, place of, treatment whether there was pharmacy treatment or self-medication, healthcare worker (HCW) inquiries about source of infection and whether the HCW was polite...

OBJECTIVES: Prior studies suggest that the composition of the vaginal microbiome may positively or negatively affect susceptibility to sexually transmitted infections (STI) and bacterial vaginosis (BV). Some female hormonal contraceptive methods also appear to positively or negatively influence STI transmission and BV. Therefore changes in the vaginal microbiome that are associated with different contraceptive methods may explain, in part, effects on STI transmission and BV. STUDY DESIGN: We performed a retrospective study of 16S rRNA gene survey data of vaginal samples from a subset of participants from the Human Vaginal Microbiome Project at Virginia Commonwealth University...

INTRODUCTION: African American (AA) high school-age girls are more likely to have had sex before age 13 years and have higher rates of all sexually transmitted infections. Cognition and religion/spirituality are associated with adolescent sexuality, therefore, the purpose of this study was to identify cognitive and religious substrates of AA girls' risky sexual behaviors. METHOD: A descriptive study was conducted with 65 AA girls aged 15 to 20 years using computerized questionnaires and cognitive function tasks...

The pandemic potential of zoonotic pathogens lies in their ability to become efficiently transmissible amongst humans. Here, we focus on contact-transmitted pathogens and discuss the factors, at the pathogen, host and environmental levels that promote or hinder their human-to-human transmissibility via the following modes of contact transmission: skin contact, sexual contact, respiratory contact and multiple route contact. Factors common to several modes of transmission were immune evasion, high viral load, low infectious dose, crowding, promiscuity, and co-infections; other factors were specific for a pathogen or mode of contact transmission...

INTRODUCTION: The rural areas of Northern Thailand are home to a large cultural diversity of ethnic minority groups. Previous studies have shown that young people in rural Thailand have low levels of knowledge on HIV/AIDS and high sexual risks. We compared sexual behaviors between the lowland Thai youth and the youth from ethnic minority groups. METHODS AND FINDINGS: This is a cross-sectional quantitative study conducted among high-school Thai and ethnic students in Chiang Mai...

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 the discussion of how PrEP may impact STI control efforts, especially in the setting of increasing Neisseria gonorrhoeae antimicrobial resistance and the increase in syphilis cases among MSM...

Infections with human papillomavirus (HPV) are common and transmitted by direct contact. Although the great majority of infections resolve within 2 years, 13 phylogenetically related, sexually transmitted HPV genotypes, notably HPV16, cause - if not controlled immunologically or by screening - virtually all cervical cancers worldwide, a large fraction of other anogenital cancers and an increasing proportion of oropharyngeal cancers. The carcinogenicity of these HPV types results primarily from the activity of the oncoproteins E6 and E7, which impair growth regulatory pathways...

Swingers are couples practicing consensual extradyadic heterosexual relations. This subculture is defined by venues, and online communities. This study aimed to assess swingers' lifestyle, sexual health, history of testing for sexually transmitted infections (STI), and review risk factors for sexual risk behavior and STI transmission. An online survey was distributed through venues, chat- and dating websites. Most of 480 swingers starting the survey completed it (n = 392, 81.6%). Women (n = 146) reported more frequent swinging (p = 0...

Pre-exposure prophylaxis (PrEP), in combination with traditional prevention strategies (such as condom use, voluntary HIV counseling and testing, and treatment for sexually transmitted infections), has been shown to effectively prevent HIV infection. As of September 2015, the World Health Organization recommends that people at substantial risk of HIV infection should be offered PrEP as an additional prevention choice, as part of comprehensive prevention. This article introduces how to apply a systematic review using the methodology of Grading of Recommendations Assessment, Development and Evaluation (GRADE) to write clinical guidelines...

In Latin America and the Caribbean (LAC), the sexual and reproductive health (SRH) of populations is a high priority for governments. Health information technologies (HITs) have been proposed as tools to close access gaps for SRH services. We developed an "evidence map" through a systematic search of articles published between 2005 and 2015 about the use of HITs to enhance SRH services in LAC countries. Two hundred and thirty-two registries were identified and screened. Thirty-one were eligible for full-text assessment...
