Objectives To determine whether the increase in HIV diagnoses since 1997 among men who have sex with men (MSM) in the UK reflects a rise in HIV incidence or an increase in HIV testing. Methods Estimates of HIV incidence were derived using data from UK HIV surveillance systems (HIV diagnoses; CD4 surveillance; unlinked anonymous surveys) for 1997-2004. Data on HIV testing were provided by KC60 s...

Mesoporous silica materials (MSMs) were synthesized economically using silica (SiO2) as a precursor via a modified alkaline fusion method. The MSM prepared at 500°C (MSM-500) had the highest surface area, pore size, and volume, and the results of isotherms and the kinetics of ibuprofen (IBP) removal indicated that MSM-500 had the highest sorption capacity and fastest removal speed vs. SBA-15 an...

BACKGROUND Australia has experienced rising notifications of HIV diagnoses despite widely available combination antiretroviral therapy (CART). New HIV diagnoses have also been younger than the average age of those living with HIV. We investigated the degree to which several risk factors could explain this rise in notifications and the younger age profile. METHODS Numbers and ages of men who h...

Men who have sex with men (MSM) have been represented disproportionately in the HIV epidemic in high income countries since the first HIV/AIDS cases were reported in MSM in 1981. Among all vulnerable HIV populations, MSM account for the preponderance of prevalent AIDS cases in Western Europe [1,2]. Similarly, the largest numbers of persons with newly diagnosed HIV infections (range 45%–65%) are...

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. ...

BACKGROUND Northern Thailand has a high burden HIV epidemic among MSM and TG. Oral pre-exposure prophylaxis (PrEP) with tenofovir-emtricitabine has demonstrated efficacy in preventing HIV among MSM and TG in Chiang Mai, Thailand. Determinants of PrEP acceptability are needed to gauge the potential uptake of this prevention strategy. METHODS From January to February 2012, 238 MSM and TG partic...

BACKGROUND HIV prevalence among men who have sex with men (MSM) in China has rapidly increased in recent years. It is suggested that MSM could be a potential bridge of HIV transmission to the general female population. We investigated the bisexual behaviour of MSM in China through systematic review and meta-analysis. METHODS We conducted a systematic review and meta-analyses on published peer...

The men-having-sex-with-men (MSM) population has become one of the major risk groups for HIV-1 infection in the Asia Pacific countries. Hong Kong is located in the centre of Asia and the transmission history of HIV-1 subtype B transmission among MSM remained unclear. The aim of this study was to investigate the transmission dynamics of HIV-1 subtype B virus in the Hong Kong MSM population. Samp...

BACKGROUND Indian cultural tradition demanding marriage, many MSM howsoever they self-identify are likely to be married or have sex with women. To consolidate India's HIV prevention gains, it is important to understand and address the interaction between the MSM and heterosexual epidemics in India and create specific interventions for bisexual MSM. The challenge is to identify and intervene thi...

Despite constituting only about 1% of Ghana’s population, men who have sex with (MSM) carry a disproportionate burden HIV infections, 18% the population people living in country. Scholars associated infection rates among MSM existing structural factors (such as criminalization and stigma against MSM), individual-level without condom, transactional sex). Nonetheless, limited scholars consider in...
