Marginalized groups in Manitoba, Canada, especially females and people who inject drugs, are overrepresented in new HIV diagnoses and disproportionately affected by HIV and structural disadvantages. Informed by syndemic theory, our aim was to understand people living with HIV's (PLHIV) gendered and intersecting barriers and facilitators across the cascade of HIV care before and during the COVID-19 pandemic. This study was co-designed and co-led alongside people with lived experience and a research advisory committee.

Unlabelled: The iSOLVE implementation project established and evaluated integrated processes and pathways, including a decision-making tool and educational interventions for general medical practitioners (GPs) and the upskilling of allied health professionals (AHPs). The study used a mixed-methods (parallel) design comprising surveys, qualitative methodologies, and an embedded cluster randomized controlled trial (RCT). Sampling was conducted within a Primary Health Network (PHN) geographic area in Sydney, Australia.

Purpose: Falls are a major concern for people with Parkinson's disease (PwPD) due to associated motor and non-motor impairments. Promoting safe mobility behaviour may be an effective fall prevention intervention, however this concept is poorly articulated in the literature. The aim of this scoping review was to map out the definition and concepts of safe mobility behaviour to draw implications for PwPD.

Objectives: Describe the proportion of people newly living with HIV with sexually transmitted and blood-borne infections (STBBIs) before, at, and after HIV diagnosis in Manitoba, Canada.

Methods: A retrospective cohort study reviewed clinical charts of all 404 people ≥18 years old newly diagnosed with HIV in Manitoba, Canada between 2018 and 2021. Syphilis, hepatitis C and B, gonorrhea, and chlamydia infections before, at, and after HIV diagnosis were recorded and analyzed by sex at birth, injection drug use status, use of methamphetamines, and housing status.

Purpose: This study examined how solvent-skin-solute interactions influenced the human epidermal permeation of three similar-sized phenolic compounds applied in a series of different solvents.

Methods: Human epidermal permeation fluxes and lag times of three phenolic compounds were assessed in Franz cells for a range of solvents varying in molecular size and solubility parameters. In order to develop a mechanistic understanding of the determinants of the permeation findings, the solubility of the compounds in solvents and stratum corneum, the extent of solvent uptake by the stratum corneum and the impact of the solvents on skin hydration and transepidermal water loss were also measured.
