BACKGROUND: Efforts to improve HIV diagnosis and antiretroviral therapy (ART) initiation among people living with HIV and reduce onward transmission of HIV rely on innovative interventions along multiple steps of the HIV care continuum. These innovative methods are particularly important for key populations, including men who have sex with men (MSM) and transgender women (TW). The HIV epidemic in Myanmar is concentrated among key populations, and national efforts now focus on reducing stigma and improving engagement of MSM and TW in HIV prevention and care...

OBJECTIVES: The average alcohol consumption per capita among Vietnamese adults has consistently increased. Although alcohol-related disorders have been extensively studied, there is a paucity of research shedding light on this issue among Internet users. The study aimed to examine the severity of alcohol-related disorders and other associated factors that might predispose individuals towards alcohol usage in a sample of youths recruited online. METHODS: An online cross-sectional study was conducted with 1,080 Vietnamese youths...

Using respondent driven sampling, we conducted a cross-sectional bio-behavioral survey among men who have sex with men (MSM) in Bamako, Mali. Eligibility criteria included age ≥18 years and having had sex with another man in the last 6 months. We enrolled 552 MSM, 99.6% were tested for HIV. MSM in Bamako were young (69.6% ≤24 years) and educated (63.7% ≥secondary). HIV prevalence among MSM in Bamako was 13.7; 90.1% of HIV-infected men were unaware of their HIV status. Almost one-third had never been tested for HIV...

Chronic inflammatory diseases (CIDs), including Crohn's disease and ulcerative colitis (inflammatory bowel diseases, IBD), rheumatoid arthritis, psoriasis, psoriatic arthritis, spondyloarthritides, hidradenitis suppurativa, and immune-mediated uveitis, are treated with biologics targeting the pro-inflammatory molecule tumour necrosis factor-α (TNF) (i.e., TNF inhibitors). Approximately one-third of the patients do not respond to the treatment. Genetics and lifestyle may affect the treatment results. The aims of this multidisciplinary collaboration are to identify (1) molecular signatures of prognostic value to help tailor treatment decisions to an individual likely to initiate TNF inhibitor therapy, followed by (2) lifestyle factors that support achievement of optimised treatment outcome...

Persons who inject drugs (PWID) are at risk for adverse health outcomes as a result of their drug use, and the resulting social stigma makes this a difficult population to reach for interventions aimed at reducing morbidity and mortality. During our study of adult PWID aged ≤40 years living in San Diego during 2009 and 2010, we compared three different sampling methods: respondent-driven sampling (RDS), venue-based sampling at one syringe exchange program (SEP), and street-based outreach. We compared demographic, socioeconomic, health, and behavioral factors and tested participants for HIV, hepatitis B virus (HBV), and hepatitis C virus (HCV) and compared across the three methods...

BACKGROUND: Injection drug use has not been well documented in American Indians living in the USA. American Indian and Alaskan Natives (AI/ANs) show higher rates of substance use compared to the general population, and have historically been subject to a number of risk factors that are known to increase the likelihood of substance use. AI/ANs also experience increased risk for infectious diseases that are transmitted via injection drug use and/or sexual activity. Harm reduction approaches have been shown to be effective for decreasing risk of disease transmission in at-risk populations, and may be well suited for AI/AN injection drug users residing in rural reservation communities...

The interpersonal determinants of condomless anal sex (CAS) within online-initiated sexual relationships remain poorly understood. Therefore, respondent-driven sampling was used to recruit a prospective cohort of sexually active gay, bisexual, and other men who have sex with men (MSM), aged ≥ 16 years in Vancouver, Canada. Follow-up occurred every 6 months, up to seven visits; at each visit participants reported their last sexual encounter with their five most recent partners. Stratified by self-reported HIV status, individual-level, interpersonal, and situational covariates of event-level CAS with partners met online were modeled using generalized estimating equations (GEE)...

INTRODUCTION: Among men who have sex with men (MSM), men who sell sex (MSS) may be subject to increased sexual behaviour-related stigma that affects uptake of healthcare and risk of sexually transmitted infections (STIs). The objectives of this study were to characterize stigma, access to care, and prevalence of HIV among MSS in Nigeria. METHODS: Respondent-driven sampling was used to recruit MSM in Abuja and Lagos into the ongoing TRUST/RV368 study, which provides HIV testing and treatment...

BACKGROUND: Salmonella is one of the most significant food-borne pathogens to affect humans and agriculture. While it is well documented that Salmonella infection triggers host inflammation, the impacts on the gut environment are largely unknown. A CBA/J mouse model was used to evaluate intestinal responses to Salmonella-induced inflammation. In parallel, we evaluated chemically induced inflammation by dextran sodium sulfate (DSS) and a non-inflammation control. We profiled gut microbial diversity by sequencing 16S ribosomal ribonucleic acid (rRNA) genes from fecal and cecal samples...

In 2014, Black/African-American and Hispanic/Latino men who have sex with men (BLMSM) comprised 64.1% of HIV diagnoses among MSM in the U.S. Routine HIV testing allows earlier diagnosis, linkage to care, and improved health outcomes. HIV testing campaigns may increase HIV awareness and testing behaviors, but perceptions of these campaigns by BLMSM have been understudied. We explored perceptions of HIV testing campaigns with BLMSM in New York City (NYC) to inform campaign strategies that target BLMSM for HIV testing...

BACKGROUND: Immunotherapy has changed the therapeutic landscape in oncology. Advanced uterine leiomyosarcoma (ULMS) remains an incurable disease in most cases, and despite new drug approvals, improvements in overall survival have been modest at best. The goal of this study was to evaluate programmed-death 1 (PD-1) inhibition with nivolumab in this patient population. METHODS: This single-center phase 2 trial completed enrollment between May and October 2015. Patients received 3 mg/kg of intravenous nivolumab on day 1 of each 2-week cycle until disease progression or unacceptable toxicity...

Associations between theorized sociocultural factors and acculturative stress were examined among Latina immigrants (aged 18-23 years) during their initial months in the US. Participants' quantity of alcohol use was hypothesized to be linked with more acculturative stress. Using respondent-driven sampling, 530 Latinas who recently immigrated to Miami-Dade County, Florida, were recruited from community activities, Latino health fairs, advertisements at community agencies, and online postings. A path analysis revealed associations between acculturative stress and more time in the US and greater commitment to ethnic identity...

INTRODUCTION: We identified the prevalence and correlates of past-year illicit drug use among transgender people in Ontario, Canada, and disparities with the age-standardized non-transgender population. METHODS: Data on transgender persons aged 16+ (n=406) were obtained from Trans PULSE, a respondent-driven sampling (RDS) survey (2009-2010). Overall and sex-specific estimates of past-year drug use (cocaine and amphetamines, based on data availability) in the reference population were obtained from Ontario residents aged 16+ (n=39, 980) in the Canadian Community Health Survey (2009-2010), and standardized to the overall and gender-specific transgender age distributions...

Progestin is commonly used for young patients suffering from endometrial hyperplasia or cancer. However, there is approximately 30% failure rate with unclear mechanism. We investigated if Nrf2-survivin pathway contributes the progestin resistance (PR) in this setting. Current study detected Nrf2 and survivin protein expression in post progestin treated endometrial tissue samples by using immunohistochemistry. Transfection of Nrf2 and survivin into endometrial cancer cells in vitro was done to determine the roles of Nrf2 and survivin in progestin resistance...

Few studies in Brazil have focused on violence against female sex workers, a theme that has attracted researchers' attention worldwide, especially due to possible associations with HIV. The current study aims to estimate the prevalence of violence against female sex workers according to type and perpetrator and to identify associated factors. A cross-sectional study was conducted with data on 2,523 female sex workers from ten Brazilian cities, and with the respondent-driven sampling (RDS). Prevalence of verbal violence was 59...
