HIV, Sexually Transmitted Infections and Sexual Practices Among Male Sex Workers Attending a Sexual Health Clinic in Melbourne, Australia: 2010 to 2018

Condomless Anal Sex Between Male Sex Workers and Clients in the Age of Hookup Apps

Among men who have sex with men (MSM), those who also engage in the exchange of sex for money, drugs, shelter or other material goods (i.e., male sex workers-MSWs) have been found to have higher rates of condomless anal sex (CAS), HIV, and STIs than MSM who do not engage in exchange sex. To gain a better understanding of the factors that influence MSWs' engagement in CAS with male clients, we analyzed qualitative interview data from a diverse sample of 141 MSWs from 8 U.S. cities who met clients primarily through hookup or dating apps/websites and who reported having condomless anal sex with at least one of their exchange sex partners in the prior three months. While high client demand and financial incentives were the most frequently mentioned reasons for engaging in CAS with clients, other factors including drug and alcohol use, attraction to the client, the heat of the moment, concerns about sexual performance, and reliance on pre-exposure prophylaxis (PrEP) were also important. Participants who engaged in CAS generally felt that due to client characteristics or mitigating steps they had taken themselves, their chance of acquiring HIV/STIs was acceptably low. Hookup or dating apps/websites have provided an additional and increasingly popular venue for exchange sex to be arranged. These platforms also offer an opportunity for HIV/STI prevention through interventions and tailored messages delivered through these venues that address the motivations, misconceptions and/or situational factors that may lead to CAS.

Global, regional, and national disease burden and attributable risk factors of HIV/AIDS in older adults aged 70 years and above: a trend analysis based on the Global Burden of Disease study 2019

We aimed to assess the burden and trend of the HIV/AIDS epidemic among older adults over the past three decades at different geographical levels, based on the data collected from the Global Burden of Diseases (GBD) study 2019. This assessment identified the average annual percentage changes (AAPCs) using Joinpoint regression analysis. Globally, the incidence of HIV/AIDS has decreased (AAPC = -3.107); however, the overall prevalence has consistently increased (AAPC = 5.557). Additionally, both mortality (AAPC = 2.166) and disability-adjusted life years (DALYs; AAPC = 2.429) have increased. The highest increasing trends in female HIV/AIDS incidence and prevalence were observed in the Central Asia region. However, for males, these trends were observed in the Oceania region and the high-income Asia Pacific region, respectively. In recent decades, females aged 70-74 years had the highest incidence and prevalence, while males aged 70-74 years had highest mortality and DALYs in low social development index (SDI) regions. Unsafe sex resulted in 15 381.16 deaths, accounting for 90.73% of all HIV/AIDS deaths, and 331 140.56 DALYs, accounting for 91.12% of all HIV/AIDS DALYs. The HIV/AIDS disease burden differs by region, age, and sex among older adults. Sexual health education and targeted screening for older adults are recommended.

Perceived risk and condomless sex practice with commercial and non-commercial sexual partners of male migrant sex workers in London, UK

Background: Since the emergence of HIV and the AIDS pandemic, the majority of risk-reduction interventions have been centred on the use of condoms in sex workers.   Methods: This qualitative study recruited 25 male migrant sex workers in London to understand their risk perception and condomless sex experiences within the context of sex work and private life. The data was collected using face-to-face interviews, analysed using thematic analysis, and the findings interpreted through the theory of planned behaviour.   Results: The themes explain that condomless sex with clients occurred when participants consciously accepted to perform this service deploying a risk assessment of clients, faulty strategies, and sexual practices to reduce their risk; or when they lost control because of recreational drugs, feeling attraction to clients, were in precarious circumstances, or were victims of violence. Conversely, condomless sex with non-commercial partners occurred according to the type of relationship, with formal partners it was rationalised through emotional aspects attached to this kind of relationship, while with casual partners it was connected to sexual arousal and the use of alcohol and drugs.  Conclusions: Reinforce educational interventions to deliver STI-HIV information, enhance the use of condoms, and to address specific contextual factors that facilitate condomless practice with commercial and non-commercial sexual partners.

Vaccine Candidates for the Control and Prevention of the Sexually Transmitted Disease Gonorrhea

The World Health Organization (WHO) has placed N. gonorrhoeae on the global priority list of antimicrobial resistant pathogens and is urgently seeking the development of new intervention strategies. N. gonorrhoeae causes 86.9 million cases globally per annum. The effects of gonococcal disease are seen predominantly in women and children and especially in the Australian Indigenous community. While economic modelling suggests that this infection alone may directly cost the USA health care system USD 11.0–20.6 billion, indirect costs associated with adverse disease and pregnancy outcomes, disease prevention, and productivity loss, mean that the overall effect of the disease is far greater still. In this review, we summate the current progress towards the development of a gonorrhea vaccine and describe the clinical trials being undertaken in Australia to assess the efficacy of the current formulation of Bexsero^® in controlling disease.
