Explicit Relationship Agreements and HIV Pre-exposure Prophylaxis Use by Gay and Bisexual Men in Relationships.

Relationship agreements are important for HIV prevention among gay and bisexual men (GBM) in relationships, with research earlier in the HIV epidemic often finding that agreements specified monogamy or condom use with casual partners. There is evidence that HIV pre-exposure prophylaxis (PrEP) has shifted sexual practices among some men in relationships, such as allowing condomless sex with casual partners, but there has been little attention paid to relationship agreements among GBM who use PrEP. In this paper, we analyzed national, Australian, cross-sectional data from an online survey completed by non-HIV-positive GBM in 2021 (N = 1,185). Using logistic regression, we identified demographic characteristics, sexual practices and the types of relationship agreement that were associated with PrEP use among GBM in relationships. Using Pearson's chi-squared tests, we explored whether PrEP users in relationships reported similar sexual practices to PrEP users not in relationships. PrEP use among GBM in relationships was independently associated with older age, identifying as gay, being in a non-monogamous relationship, having a spoken (explicit) relationship agreement, having a primary HIV-negative partner taking PrEP or a primary partner living with HIV, reporting recent condomless casual sex, reporting an STI diagnosis in the past year, and knowing at least one other PrEP user. We found that PrEP users in relationships had similar sexual practices to PrEP users not in relationships. GBM in relationships who have casual sex and who meet PrEP suitability criteria may be good candidates for PrEP. Our findings suggest that explicit relationship agreements remain important for HIV prevention, and they support PrEP use among GBM in relationships.

Familiarity with, perceived accuracy of, and willingness to rely on Undetectable=Untransmittable (U=U) among gay and bisexual men in Australia: results of a national cross-sectional survey.

BACKGROUND: The Undetectable=Untransmittable (U=U) message has been promoted since it was demonstrated that viral suppression through HIV treatment prevents sexual transmission between serodiscordant partners (HIV treatment as prevention). Our study assessed familiarity with, perceived accuracy of, and willingness to rely on U=U in a national sample of gay and bisexual men in Australia. METHODS: We conducted a national, online cross-sectional survey in April-June 2021. Eligible participants were gay, bisexual and queer men and non-binary people who lived in Australia. Logistic regression was used to identify factors associated with familiarity, perceived accuracy and willingness to rely on U=U (by having condomless sex with a partner with HIV who has an undetectable viral load). RESULTS: Of 1280 participants, most were familiar with U=U (1006/1280; 78.6%), the majority of whom believed U=U was accurate (677/1006; 67.3%). Both familiarity and perceived accuracy were higher among participants living with HIV, followed by pre-exposure prophylaxis (PrEP) users, HIV-negative participants not taking PrEP, and untested/unknown status participants. Knowing at least one person living with HIV, among other factors, was associated with familiarity and perceived accuracy of U=U; and familiarity was associated with perceived accuracy. Among participants familiar with U=U, less than half were willing to rely on U=U (473/1006; 47.0%). Familiarity with U=U and knowing at least one person living with HIV were associated with willingness to rely on U=U, among other factors. CONCLUSIONS: We found familiarity with U=U was associated with perceived accuracy and willingness to rely upon it. There is an ongoing need to educate gay and bisexual men (particularly HIV-negative men) about U=U and its benefits.

COVID-19 Vaccination Uptake and Hesitancy in a National Sample of Australian Gay and Bisexual Men.

Minority groups may face additional barriers to vaccination. In April-June 2021, we assessed the level of COVID-19 vaccination and willingness to be vaccinated in a national, online survey of 1280 gay and bisexual men in Australia. Over a quarter of the sample (28.0%) had been partially or fully vaccinated, and 80.0% of the unvaccinated were willing to be vaccinated. Vaccination was independently associated with older age, being university educated, and HIV status (with HIV-positive participants being more likely and untested participants less likely to be vaccinated). Willingness to be vaccinated was independently associated with living in a capital city and being university educated. Those who had lost income or their job due to COVID-19 were less willing to be vaccinated. Our results suggest encouraging COVID-19 vaccination among those with lower levels of health literacy and supporting those who have experienced financial stress because of the pandemic.

RESUMEN: Los grupos minoritarios pueden enfrentar barreras adicionales accediendo a una vacuna. En abril-junio de 2021, evaluamos el nivel de vacunación contra el COVID-19 y la disposición a la vacuna utilizando datos de una encuesta nacional en línea de 1280 hombres gays y bisexuales en Australia. El 28% de los participantes habían sido vacunados parcial o totalmente, y el 80% de los no vacunados estaban dispuestos a vacunarse. La vacunación se asoció de forma independiente con participantes de mayor edad, con educación universitaria y su estado de VIH (los participantes VIH positivos tenían más probabilidades que los participantes sin prueba del VIH de ser vacunados). La disposición a favor de ser vacunados se asoció de manera independiente con vivir en una ciudad capital y tener estudios universitarios. Aquellos que habían perdido ingresos o su trabajo debido al COVID-19 estaban menos dispuestos a vacunarse. Nuestros hallazgos sugieren que es importante promover la vacunación contra el COVID-19 entre personas que tienen menos información en temas de salud y apoyar a quienes han sufrido estrés financiero debido a la pandemia.

Individual level peer interventions for gay and bisexual men who have sex with men between 2000 and 2020: A scoping review.

BACKGROUND: Peer-led interventions are central to the global HIV response for gay and bisexual men who have sex with men [GBMSM]. Since the year 2000, technological advancements in HIV and an increased response to the health disparities faced by GBMSM outside of HIV, have contributed to the expanding scope of their content and delivery. This review sets out to characterise the evidence base for individual level peer interventions for GBMSM, overview approaches to implementing and evaluating them and identify future priorities for their delivery and evaluation. METHODS: A scoping review methodology was applied and evaluations of peer programs for GBMSM published in peer reviewed journals were identified via subject heading and keyword searches across five electronic databases. Titles and abstracts were reviewed, and full texts were assessed against eligibility criteria. A coding framework was used to extract data from included studies against intervention implementation and evaluation components. RESULTS: A total of 38 studies evaluating peer led interventions against effectiveness outcomes were deemed eligible for inclusion and coded into four intervention modalities; peer counselling [n = 6], groupwork programs [n = 15], peer navigation [n = 7] and peer education [n = 10]. Most addressed HIV [n = 32] and across intervention modalities, evaluations demonstrated compelling evidence of significant effect. Intervention effects on broader indicators of psychosocial wellbeing were not extensively evaluated. Expertise regarding the implementation and evaluation of peer interventions addressing HIV among GBMSM ought to be leveraged to expand the scope of peer intervention to meet the diverse health and wellbeing needs of GBMSM.

Digital Pathology Transformation in a Supraregional Germ Cell Tumour Network.

BACKGROUND: In this article we share our experience of creating a digital pathology (DP) supraregional germ cell tumour service, including full digitisation of the central laboratory. METHODS: DP infrastructure (Philips) was deployed across our hospital network to allow full central digitisation with partial digitisation of two peripheral sites in the supraregional testis germ cell tumour network. We used a survey-based approach to capture the quantitative and qualitative experiences of the multidisciplinary teams involved. RESULTS: The deployment enabled case sharing for the purposes of diagnostic reporting, second opinion, and supraregional review. DP was seen as a positive step forward for the departments involved, and for the wider germ cell tumour network, and was completed without significant issues. Whilst there were challenges, the transition to DP was regarded as worthwhile, and examples of benefits to patients are already recognised. CONCLUSION: Pathology networks, including highly specialised services, such as in this study, are ideally suited to be digitised. We highlight many of the benefits but also the challenges that must be overcome for such clinical transformation. Overall, from the survey, the change was seen as universally positive for our service and highlights the importance of engagement of the whole team to achieve success.

"Masson's pseudoangiosarcoma" in a popliteal aneurysm: tumor or thrombus? Cause or effect?

A 44-year-old male presented to our vascular surgery unit with a partially thrombosed 22 mm popliteal aneurysm giving rise to progressive distal ischemia. Microscopy of embolus retrieved from the posterior tibial artery at bypass surgery revealed the unexpected finding of intravascular papillary endothelial hyperplasia (Masson's pseudoangiosarcoma).

Unsuspected pulmonary alveolar proteinosis in a patient with a slow resolving pneumonia: A case report.

Parotid pleomorphic adenoma with solitary renal metastasis.

We present a rare case of renal metastasis of a recurrent pleomorphic adenoma of the parotid gland in an elderly woman. Metastasising pleomorphic adenoma shows malignant clinical behaviour, and although it appears histologically benign, there may be unknown molecular features that determine its unusual ability to spread.
