Correlates of Using Medically-Authorized Cannabis in a Large Cohort of People Living with HIV Who Use Cannabis.

Many people living with HIV (PLWH) use cannabis to manage symptoms, but a large proportion do so without medical cannabis authorization and use cannabis obtained outside the medical stream. In jurisdictions where non-medical cannabis use is legal, PLWH who hold medical cannabis authorization may represent a unique subgroup; yet, research on the correlates of using medical cannabis (authorized by a healthcare provider) in the context of non-medical cannabis legalization is lacking. Thus, this study examined the cannabis- and health-related correlates of medical cannabis use among PLWH in Ontario, Canada, where non-medical cannabis is legal.

Sex differences in COVID-19 vaccine confidence in people living with HIV in Canada.

Background: Understanding the roots of vaccine confidence in vulnerable populations, such as persons living with HIV (PLWH), is important to facilitate vaccine uptake, thus mitigating infection and spread of vaccine-preventable infectious diseases. In an online survey of PLWH conducted in Canada during winter 2022 (), we reported that the overall COVID-19 vaccination uptake rate in PLWH was similar by sex. Here, we examined attitudes and beliefs towards vaccination against COVID-19 based on sex.

Coronavirus disease 2019 outcomes in a population-based cohort of people with HIV and a matched cohort of people without HIV during Omicron variant waves.

We found that rates of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) testing and reverse transcriptase (RT)-PCR-confirmed infection were approximately 50% higher in a population-based cohort of people with HIV compared with a matched cohort of people without HIV during the Omicron era (2 January 2022 to 31 March 2023) in Ontario, Canada, after controlling for age, sex, residential census tract, and country of birth. Rates of coronavirus disease 2019 (COVID-19)-related hospitalization and/or death were more than double. Differences persisted independent of vaccination, healthcare access, and COVID-19 diagnosis.

Associations of CD4 Cell Count Measures With Infection-Related and Infection-Unrelated Cancer Risk Among People With HIV.

Background: People with HIV are at higher risk of infection-related cancers than the general population, which could be due, in part, to immune dysfunction. Our objective was to examine associations between 4 CD4 count measures as indicators of immune function and infection-related and infection-unrelated cancer risk.

Setting: We conducted a cohort study of adults with HIV who were diagnosed with cancer in Ontario, Canada.

Testing for extragenital Neisseria gonorrhoeae and Chlamydia trachomatis: At-home pharyngeal and rectal self-swabs are non-inferior to those completed in healthcare settings.

Introduction: The rates of gonorrhea and chlamydia have been increasing in the years preceding the COVID19 pandemic. Because most gonorrhea and chlamydia infections are located in the oropharynx and rectum for men who have sex with men (MSM), and because at-home self-collected swabs for these infections are not licensed by Health Canada or the United States Food and Drug Administration, decreased accessed to in-person care during and since the COVID19 pandemic potentially means missed case findings.

Objectives: To evaluate the performance of at-home self-collected pharyngeal and rectal swabs for gonorrhea and chlamydia nucleic acid amplification testing.
