Theory of change to develop a health and well-being complex intervention for people with HIV
INTRODUCTION: There is a high prevalence of poor mental health among people with HIV, intersecting with structural inequalities, stigma and co-morbidities. A new person-centred approach to care that utilises health coaching to prioritise health and well-being and connects people to existing sources of support or voluntary sector organisations (social prescribing) could benefit people with HIV. METHODS: Theory of Change (ToC) methodology was used …
An (un)restricted living
People living with HIV, who have access to treatment, now have normal life expectancy. However, stigma and discrimination continue to affect health and well-being. We conducted focus groups with people living with HIV (n = 37), and key informant interviews (n = 20) with clinical and non-clinical workers who support people with HIV between May and November 2023. We aimed to explore the ongoing challenges and concerns faced by people living with HI…

Recreational drug use and use of drugs associated with chemsex among HIV-negative and HIV-positive heterosexual men and women attending sexual health and HIV clinics in England
Providers need to be aware of cannabis and cocaine use and its potential link with sexual risk behavior and symptoms of depression and anxiety among heterosexual men and women attending sexual health and HIV clinics
Risk of HIV transmission through condomless sex in serodifferent gay couples with the HIV-positive partner taking suppressive antiretroviral therapy (PARTNER)
BACKGROUND: The level of evidence for HIV transmission risk through condomless sex in serodifferent gay couples with the HIV-positive partner taking virally suppressive antiretroviral therapy (ART) is limited compared with the evidence available for transmission risk in heterosexual couples. The aim of the second phase of the PARTNER study (PARTNER2) was to provide precise estimates of transmission risk in gay serodifferent partnerships. METHODS:…
Investigating Conceptual Models for the Relationship Between Depression and Condomless Sex Among Gay, Bisexual, and Other Men Who have Sex with Men
The aim of this study is to investigate five hypothesized mechanisms of causation between depression and condomless sex with ≥ 2 partners (CLS2+) among gay, bisexual, and other men who have sex with men (GBMSM), involving alternative roles of self-efficacy for sexual safety and recreational drug use. Data were from the AURAH cross-sectional study of 1340 GBMSM attending genitourinary medicine clinics in England (2013-2014). Structural equation mo…
Changes in chemsex and sexual behaviour over time, among a cohort of MSM in London and Brighton
Chemsex and use of two individual chemsex drugs (mephedrone and GHB/GBL) significantly declined over time among individuals in the study, alongside most measures of sexual behaviour with the exception of those related to CLAI. Focusing health promotion and HIV prevention, such as awareness of post-exposure prophylaxis (PEP) and access to pre-exposure prophylaxis (PrEP), on MSM that report chemsex, and in particular problematic chemsex, would be h…

The Shape of the City
Critics have long voiced concerns about the wisdom of living in cities and the effects of city life on physical and mental health. For a century, planners have tried to meet these issues. John Sewell traces changes in urban planning, from the pre-Depression garden cities to postwar modernism and a revival of interest in the streetscape grid.In this far-ranging review, Sewell recounts the arrival of modern city planning with its emphasis on lower …
