INTRODUCTION: New interventions are required to reduce unintended pregnancies among female sex workers (FSWs) in low- and middle-income countries and to improve their nutritional health. Given sex workers' high mobile phone usage, repeated exposure to short messaging service (SMS) messages could address individual and interpersonal barriers to contraceptive uptake and better nutrition. METHODS: In this two-arm cluster randomised trial, each arm constitutes an equal-attention control group for the other...

INTRODUCTION: Globally, there are 3.3 million children < 15 years of age living with HIV infection. About 95% of HIV infected children have acquired infection from their mothers. Although new pediatric HIV infection in Tanzania has declined by 48% and Prevention of Mother to Child Transmission (PMTCT) coverage of highly active anti-retroviral therapy (HAART) has increased to 77%, the MTCT rate remains high (15%). Poor male partner involvement in PMTCT services is one of the factors contributing to reduced effectiveness of the PMTCT and hence failure to achieve the elimination of maternal to child transmission of HIV...

BACKGROUND: Increasing overall rates, and frequency, of HIV testing in populations at risk is a key public health objective and a critical dimension of HIV prevention efforts. In the UK, men who have sex with men (MSM) remain one of the communities most at risk of HIV and, within this, young gay men are a key risk group. Understanding HIV testing practices is important in the development of interventions to promote testing among young gay and bisexual men. METHODS: Qualitative interviews were conducted with thirty young gay and bisexual men (aged 18-29) in Scotland...

The primary aim of this study was to explore the relationship between the domains of HIV-related stigma and subjective well-being in people living with HIV ( N = 90), giving a special emphasis to the role of Belief in a Just World. A significant relationship emerged between the domains of stigma and the components of subjective well-being, which is not direct, but is rather mediated by Belief in a Just World. The findings indicate that exposure to stigma can lead to a decrease in Belief in a Just World, which potentially leads to a sense of lack of control over one's life, with a final, negative outcome for subjective well-being...

In the United States, an estimated 25% of men who have sex with men (MSM) have indications for receiving pre-exposure prophylaxis to prevent HIV infection (PrEP), but <4% reported PrEP use in the past 12 months. We evaluate factors associated with having heard of, willingness to use, and use of PrEP in a venue-based, time-spaced sample of 316 urban, highly insured Boston MSM in the 2014 NHBS. We found that 53.7% of respondents reported receiving usual medical care from a doctor's office or health maintenance organization, 57...

REVIEW
Jennifer Velloza, Renee Heffron
PURPOSE OF REVIEW: This review describes existing evidence addressing the potential modulation of pre-exposure prophylaxis (PrEP) products, specifically 1% tenofovir (TFV) gel and oral tenofovir-based PrEP, by vaginal dysbiosis and discusses future considerations for delivering novel, long-acting PrEP products to women at high risk for vaginal dysbiosis and HIV. RECENT FINDINGS: We describe results from analyses investigating the modification of PrEP efficacy by vaginal dysbiosis and studies of biological mechanisms that could render PrEP ineffective in the presence of specific microbiota...

BACKGROUND: Female Sex Workers (FSWs) are main drivers of the HIV epidemic in Nepal. The work environment of sex work in Nepal is differentiated into establishment based (e.g. massage parlors, dance restaurants, hotels and lodges) and street based (e.g. streets, parks and markets). The study compares HIV, syphilis and risk behaviours among establishment-based FSWs and street-based FSWs in Kathmandu Valley of Nepal. MATERIALS AND METHODS: Cross-sectional bio-behavioral surveys in 2006, 2008, 2011 and 2015 aimed to sample 2093 FSWs using two stage cluster sampling in the Kathmandu valley...

BACKGROUND: Monitoring cancer risk among HIV-infected people in the modern antiretroviral therapy (ART) era is essential given their elevated risk for many cancers and prolonged survival with immunosuppression, ART exposure, and ageing. We aimed to examine cancer risk in HIV-infected people in the USA as compared with that in the general population. METHODS: We did a registry-linkage study with data from population-based HIV and cancer registries in the USA (the HIV/AIDS Cancer Match Study)...

Latently human immunodeficiency virus (HIV)-infected cells are transcriptionally quiescent and invisible to clearance by the immune system. To demonstrate that the latency reversing agent vorinostat (VOR) induces a window of vulnerability in the latent HIV reservoir, defined as the triggering of viral antigen production sufficient in quantity and duration to allow for recognition and clearance of persisting infection, we developed a latency clearance assay (LCA). The LCA is a quantitative viral outgrowth assay (QVOA) that includes the addition of immune effectors capable of clearing cells expressing viral antigen...

Child development in low and middle income countries (LMIC) is compromised by multiple risk factors. Reducing children's exposure to harmful events is essential for early childhood development (ECD). In particular, preventing violence against children - a highly prevalent risk factor that negatively affects optimal child development - should be an intervention priority. We used the Child Health and Nutrition Initiative (CHNRI) method for the setting of research priorities in integrated Early Childhood Development and violence prevention programs (ECD+)...

Living with HIV can be both a precipitant and a consequence of partner abuse (PA) across populations, including male-male partnerships. However, overlapping experiences of living with HIV and experiencing PA are not well characterized. We conducted 24 qualitative interviews with urban HIV-positive sexual minority men (SMM) recruited from a public hospital HIV clinic in Seattle, Washington, who reported lifetime PA histories, and analyzed them using content analysis. Participants reported psychological, physical, and sexual victimization from partners, varying in severity...

Prevention of mother-to-child transmission (PMTCT) guidelines recommend that all HIV-infected pregnant woman receive antiretroviral therapy (Option B) and HIV-infected infants should initiate therapy with a protease inhibitor based regimen; however, implementation of these guidelines has lagged in many resource-limited settings. Tanzania only recently implemented these guidelines with little country specific data to inform whether HIV non-nucleoside reverse transcriptase inhibitor (NNRTI) resistance was present among infected infants under the Option A guidelines...

BACKGROUND: Women in the CAPRISA 004 trial assigned to use 1% tenofovir (TFV) microbicide gel, who became HIV-1 infected, had higher viral load set-point and slower antibody avidity maturation compared with placebo participants. We investigated whether TFV gel was selected for viruses with altered genetic characteristics. SETTING: The participants of the CAPRISA 004 trial (n = 28 TFV and 43 placebo) were from KwaZulu-Natal Province, South Africa and were infected with HIV-1 subtype C...

Broadly neutralizing antibodies (BnAbs) protect macaques from cell-free simian/human immunodeficiency virus (SHIV) challenge, but their efficacy against cell-associated SHIV is unclear. Virus in cell-associated format is highly infectious, present in transmission-competent bodily fluids, and potentially capable of evading antibody-mediated neutralization. The PGT121 BnAb, which recognizes an epitope consisting of the V3 loop and envelope glycans, mediates antibody-dependent cellular cytotoxicity and neutralization of cell-to-cell HIV-1 transmission...

BACKGROUND: Men who have sex with men (MSM) continue to be disproportionately affected by HIV in Malaysia. Recent success has been observed within demonstration projects examining the efficacy of HIV pre-exposure prophylaxis (PrEP), an antiretroviral -based medication taken by HIV-negative men to prevent sero-conversion. In order for such promising findings to be translated in real-world settings, it is important to understand the acceptability of PrEP, including perceived barriers to access or uptake...
