New HIV diagnoses continue to disproportionately affect overseas-born men who have sex with men (MSM). A retrospective study of all pre-exposure prophylaxis (PrEP)-eligible MSM attending Sydney Sexual Health Centre for the first time in 2021 analysed self-reported PrEP-use, PrEP prescribed at the initial consult, and PrEP taken during 2021 using binomial logistic regression models. A total of 1367 clients were included in the analysis, 716 (52.

Background: Although there is a presumption that LGBTQ+ people living in rural Australia will have poorer health outcomes than those living in metropolitan areas, minimal research has focused specifically on the perspectives of transgender and gender diverse (henceforth referred to as 'trans') people living in these regions. The purpose of this study was to understand what health and wellbeing means to trans people in a regional or rural community and identify their health needs and experiences.

Methods: A total of 21 trans people were recruited through two regional sexual health centres (SHC) and interviewed between April and August 2021.

Objectives: In 2019, informed by favourable patient and provider acceptability surveys and concerns about antimicrobial resistance, Sydney Sexual Health Centre stopped routinely providing empirical antibiotic treatment to asymptomatic contacts of (chlamydia) and (gonorrhoea). We aimed to assess if this policy change had any negative impact on patient outcomes.

Methods: A retrospective file review of people who presented as asymptomatic contacts of chlamydia and gonorrhoea cases before and after the policy change was conducted.

Objectives: Between 2013 and 2014, a third of Australian adults reported using the internet to investigate medical symptoms before consulting a medical practitioner. However, there is limited evidence regarding internet health information seeking behaviour (HISB) in sexual health. This study aims to determine the frequency, predictors and accuracy of internet HISB for sexual health self-diagnosis.

In New South Wales (NSW), Australia, innovative community-based testing models have been implemented to increase HIV testing among populations at risk. The characteristics of patients newly diagnosed with HIV at a community-based testing site and at a traditional clinical service in Sydney, NSW, were compared. Compared with the clinical service, clients diagnosed at the community-based site were more likely to be diagnosed at their first visit and report no prior HIV test.

Unlabelled: Background Previous guidelines at the Sydney Sexual Health Centre (SSHC) recommended empirical antibiotic treatment for asymptomatic contacts of Neisseria gonorrhoeae at the time of testing. With increasing concerns around gonorrhoea antibiotic resistance, it has been suggested that asymptomatic contacts should only be treated based on test results.

Methods: This retrospective study of data from the SSHC electronic medical record included a total of 295 gonorrhoea contacts from 1 January 2018 to 30 June 2018.

Adequate adherence to pre-exposure prophylaxis (PrEP) is critical to prevent HIV infection, but accurately measuring adherence remains challenging. We compared two biological [blood drug concentrations in plasma and peripheral blood mononuclear cells (PBMC)] and two self-reported measures (facilitated recall to clinicians and self-report in online surveys) and identified predictors of daily PrEP adherence among gay and bisexual men (GBM) in their first 12 months on PRELUDE, an open-label, single-arm PrEP demonstration project in New South Wales, Australia. 327 participants were enrolled; 263 GBM attended their 12-month follow-up visit (81% retention).

Article Synopsis
  • HIV pre-exposure prophylaxis (PrEP) is effective for reducing HIV incidence among men who have sex with men (MSM) but its broader population-level impacts were previously unclear.
  • The EPIC-NSW study recruited 3,700 high-risk gay and bisexual men in New South Wales to evaluate the effect of PrEP on HIV incidence and overall HIV diagnoses in the region.
  • Results showed a significant drop in HIV diagnoses among MSM after PrEP roll-out, with infections declining from 295 to 221, demonstrating a 25% relative risk reduction, highlighting the effectiveness of targeted PrEP distribution.

Article Synopsis
  • - The PrELUDE study in Australia assessed the effectiveness of daily PrEP (pre-exposure prophylaxis) among high-risk individuals, primarily focusing on gay and bisexual men, for 18 months.
  • - Participants showed excellent adherence to PrEP, taking an average of 7 pills weekly, with no new HIV infections reported, despite a high and stable incidence of STIs, including a notable decline in gonorrhoea rates.
  • - Findings indicated that while risk behaviors, such as increased sex with HIV-positive partners and condomless anal intercourse, rose, these were offset by high PrEP adherence, influencing public health policies regarding its use in Australia.

Sézary Syndrome (SS) is an aggressive leukemic variant of primary cutaneous T-cell lymphoma characterized by the presence of tumor or Sézary cells that generally display a mature memory T-cell immunophenotype. Sézary cells proliferate poorly and therefore their accumulation may be due to defective T-cell homeostasis involving resistance to apoptosis. In this study, we analyzed Fas expression in CD4+ lymphocytes at the mRNA and protein levels in a large cohort of SS patients as compared with healthy controls.
