Background: Women living with HIV (WLHIV) have a high risk of anal cancer. Identifying risk factors for anal HPV 16 infection, the most significant risk factor for anal cancer, is essential for prevention and screening strategies.
Methods: In the EVVA Cohort study, 151 WLHIV had cervical and anal HPV testing with genotyping every 6 months for 2 years, while demographic and clinical data were collected via questionnaires and chart reviews.
Objectives: Use of illicit substances during sex (chemsex) may increase transmission of HIV and other STIs. Pre-exposure prophylaxis (PrEP) is highly effective at preventing HIV transmission, providing an important prevention tool for those who practise chemsex. However, it does not prevent acquisition of other STIs.

- The study examines changes in the demographics and risk factors of newly diagnosed HIV-positive individuals at a sexual health clinic in Montréal from 1995 to 2019 to improve public health strategies.
- Data collected from 2,612 patients revealed that while the mean age remained stable at 35, the proportion of those diagnosed with advanced HIV infection significantly decreased from 16% in 1995 to 4% in 2019.
- Although men who have sex with men (MSM) originally made up 77% of diagnoses, their share has declined since 2013, and there is an increasing number of patients from HIV-endemic countries, particularly women, who are predominantly heterosexual.
Background: Reducing HIV transmission using pre-exposure prophylaxis (PrEP) requires focussing on individuals at high acquisition risk, such as men who have sex with men with a history of nonoccupational post-exposure prophylaxis (nPEP). This study aims to characterize longitudinal trends in PrEP uptake and its determinants among nPEP users in Montréal.
Methods: Eligible attendees at Clinique médicale l'Actuel were recruited prospectively starting in October 2000 (nPEP) and January 2013 (PrEP).
Background: Anal cancer is potentially preventable through screening. For screening to be implemented, the screening procedures must be acceptable to the affected population. The objective of the present study was to measure the acceptability of currently available anal cancer screening tests in a population of women living with hiv who had experienced the tests.
