In recent years there has been a widespread uptake of smartphones with internet access and location services and the development of mobile ‘apps’ for gay men to meet each other. We reviewed data collected in the Sydney and Melbourne Gay Community Periodic Surveys (GCPS) to identify which men were relying on mobile and internet methods to meet each other and whether these methods were associated with different risk practices.
We analysed which participants met their male sex partners through mobile apps, the internet and other methods. Data from 2010 to 2013 were included. We report linear tests for trends and used logistic regression to assess associations with meeting partners via mobiles/online.
Data from 20,064 participants were included. 14,540 (72.5%) men reported using at least one place or method to meet sex partners. From 2010 to 2013, the proportion of participants who met partners via the internet was stable. The proportion that used mobile apps to meet sex partners increased significantly from 29.7% in 2011 to 45.6% in 2013. During the same period, there were significant falls in the proportions of men who found sex partners at social venues (39.9% to 31.2%, p <.001) and sex venues (43.1% to 34.5%, p <.001).
In a logistic regression model, using mobile/online methods exclusively was associated with being younger and using serosorting for sex without condoms. However, reliance on mobile/online methods was not significantly associated with HIV status, being diagnosed with an STI or unprotected anal intercourse with casual partners.
There has been a dramatic increase in use of mobile apps to meet male partners by gay men in Sydney and Melbourne. However, men who exclusively use websites or mobile phone to meet partners do not appear to be at increased risk of STIs or HIV.
Adherence to combination antiretroviral therapy (cART ) plays an important role on treatment outcomes. The TREAT Asia Studies to Evaluate Resistance – Monitoring Cohort Study (TASER-M) collects patients’ adherence based on a Visual Analogue Scale. The aim of this analysis was to assess the rates of, and factors associated with, suboptimal adherence in the first 24 months of initial cART in Asian patients.
REACH was a collaborative research and practice initiative to develop evidence building frameworks, capacity, tools and resources with the Victorian HIV community partnership.
HIV disease is associated with chronic inflammation and activation of the innate immune system. This state, as measured using plasma markers of inflammation, persists following suppression of HIV viremia using antiretroviral therapy, and may increase risk of non-AIDS co-morbidities. The causes of innate immune activation in the setting of virological suppression are unclear. Natural killer (NK) cells are innate immune cells that kill virus-infected and transformed cells without prior sensitization. We have shown that NK cells are activated both phenotypically (elevated expression of HLA-DR) and functionally (increased spontaneous degranulation measured by CD107a surface expression) in virologically suppressed (VS) HIV+ individuals. NK cells also lose expression of CD16, the receptor which mediates antibody-dependent cellular cytotoxicity.
Regular HIV testing is recommended in men who take sexual risks. We assessed the relationship between perceived barriers to HIV testing, and frequency of testing among men who engaged in unprotected anal intercourse with casual partners (UAIC), to inform HIV testing strategies.
The majority of HIV diagnoses including delayed diagnoses in Australia occur among men who report homosexual contact – hereafter called gay and bisexual men (GBM). Delayed diagnosis is strongly associated with increased HIV-related mortality and morbidity. People who are unaware of their HIV-positive status may also be unwittingly transmitting HIV. We assessed trends in delayed HIV diagnoses among GBM in Australia.
HIV-associated leishmaniasis, endemic in the Mediterranean basin is a growing problem in India, Brazil and East Africa. Despite surviving for than 20 years, the clinical course of our visceral-leishmania (VL)-HIV co-infected patient illustrates several management challenges including diagnosis, speciation and drug resistance; monitoring burden of disease; access to and use of VL-treatments; end-organ toxicity and the combined immunosuppressive effects of HIV-VL.
As part of the adult HIV and PPTCT (The Prevention of Parent to Child Transmission) services, Clinton Health Access Initiative, in collaboration with the Papua New Guinea Department of Health and Eastern Highlands Provincial Health Authority, implemented an HIV partner testing program in a public sector health center in Eastern Highlands Province in 2007. The program aimed to facilitate partner testing and disclosure in a safe environment, remove obstacles to care, involve partners in the promotion of infant HIV-free survival, increase early case detection and treatment among individuals at high-risk of HIV, and promote adherence antiretroviral treatment among PPTCT mothers.
