Current knowledge and informal use of PrEP in Australia: available evidence from behavioural surveillance and research.

Current knowledge and informal use of PrEP in Australia: available evidence from behavioural surveillance and research.

685 participants provided information about PrEP awareness. They were on average 38 years old; 88% identified as gay and 10% as bisexual; 80% were sexually active and 33.7% had unprotected anal intercourse in preceding 6 months. Only 3.2% knew that ARVs,if taken before sex, were proven to be protective for HIV-negative homosexual men, and additional 16.5% knew about research evidence of ARV effectiveness in any situation, homosexual or heterosexual. 27 men (3.9%) had taken ARVs to reduce their chances of getting HIV in the past, but only 4 men reported using ARV both before and after having sex. If PrEP were available, 24.9% were willing to take it on daily basis, 50.1% for a few days before and after sex, 58.6% one day before and one day after having sex, and 71.8% before, during, and after a period of potentially risky sex. The likelihood to use PrEP daily was associated with engaging in unprotected anal intercourse and was highest in men with 11 or more partners in past 6 months.

Knowledge about PrEP effectiveness remains low among Australian gay men. If it were available now, most men would likely use PrEP around the time of specifically risky events or periods of potentially risky sex. Daily use would be most likely among men with high number of sex partners. There is need to inform gay men about the evidence on PrEP effectiveness and how it should be best used.

HIV and Hodgkin's lymphoma - a medical dilemma

HIV and Hodgkin's lymphoma - a medical dilemma

The case is of a 30 year-old HIV positive Zimbabwean woman (UK resident) who arrived in Australia in January 2011 on a one-year working visa. She was diagnosed with HIV in 2003 in the UK and commenced on Atripla® in 2005. She was first seen in Adelaide in May 2011, requesting a script for Atripla.®.

High Resolution Anoscopy - Practice makes perfect

High Resolution Anoscopy - Practice makes perfect

Background: Liquid based anal Papanicolaou smears, followed by High Resolution Anoscopy (HRA) guided biopsies are increasingly being advocated to identify areas of High Grade Anal Intraepithelial Neoplasia (HGAIN). We hypothesized that the ability to identify HGAIN would increase with experience of the anoscopist, and that comparison with contemporary Papanicolaou smears might yield insights into technical abilities.

An Indigenous cultural appropriateness audit piloted in a sexual health clinic in NSW: making Aboriginal and Torres Strait Islander peoples a priority.

An Indigenous cultural appropriateness audit piloted in a sexual health clinic in NSW: making Aboriginal and Torres Strait Islander peoples a priority.

Indigenous Australians experience a greater burden of sexually transmitted infections, however are less likely than the general population to access sexual health services. We examined the effectiveness of an Indigenous cultural appropriateness audit in assessing a sexual health clinic with low rates of Indigenous clients.

Chlamydia and the Urban Aboriginal Medical Service

Chlamydia and the Urban Aboriginal Medical Service

Despite the high proportion of young people annually accessing general practices, including Aboriginal Medical Services (AMS), testing for Chlamydia trachomatis remains relatively low in urban areas. A project officer was employed within the Institute of Urban Indigenous Health (IUIH) to serve a mentoring and facilitation role for the SE Queensland network of AMS and their sexual health workers, with a view to improving testing, management and follow-up of chlamydia and other STIs by community controlled medical services.

An optimised eight-colour flow cytometry protocol for the analysis of monocyte heterogeneity and monocyte activation markers during HIV infection.

An optimised eight-colour flow cytometry protocol for the analysis of monocyte heterogeneity and monocyte activation markers during HIV infection.

Monocytes are a heterogeneous cell population having specialised functions and differing phenotype. They are a link between innate immune system and adaptive immune system therefore, to identify if immune activation exists in HIV-1 individuals with controlled virema and recovered CD4 T cell counts, we assessed cell surface monocyte activation markers (MAM) within the monocyte subsets.

The Ask Share Know Project: a research translation study of three consumer questions to enhance treatment decision making

The Ask Share Know Project: a research translation study of three consumer questions to enhance treatment decision making

Involving consumers in healthcare decisions is important for high quality care. We previously tested a brief, consumer-led intervention consisting of three questions in a trial employing trained, standardized patients. The intervention enhanced discussion of evidence and increased patient involvement. We now report a research translation study which tested implementation with real patients at a reproductive and sexual health clinic.
