Alcohol consumption and mortality among Canadian drinkers: A national population-based survival analysis (2000-2017).

Introduction: Alcohol contributes significantly global disease burden. Over 50 countries, including Canada, have established low-risk drinking guidelines to reduce alcohol-related harm. Canada's Guidance on Alcohol and Health (CGAH) was released in 2023.

BD SurePath Direct to Slide (DTS) cervical cytology: Migrating the benefits of liquid-based cytology to low-resource settings.

Objectives: The benefits of liquid-based cytology (LBC) in routine cervical cancer screening are often associated with the availability of instrumented platforms and economic considerations. A low-cost alternative to LBC in low-volume settings remains an unmet need.

Methods: A multisite evaluation of the BD SurePath (SurePath) LBC Direct to Slide (DTS) method was conducted.

Community pharmacists' awareness, identification, and management of prescribing cascades: A cross-sectional survey.

Background: Prescribing cascades can lead to unnecessary medication use, healthcare costs, and patient harm. Pharmacists oversee prescriptions from multiple prescribers and are well positioned to identify such cascades, making pharmacists key stakeholders to address them.

Objectives: To evaluate community pharmacists' awareness, identification, and management of prescribing cascades and to assess behavioural determinants that may be targeted in future strategies to minimise inappropriate prescribing cascades.

Gut bacteria-derived serotonin promotes immune tolerance in early life.

The gut microbiota promotes immune system development in early life, but the interactions between the gut metabolome and immune cells in the neonatal gut remain largely undefined. Here, we demonstrate that the neonatal gut is uniquely enriched with neurotransmitters, including serotonin, and that specific gut bacteria directly produce serotonin while down-regulating monoamine oxidase A to limit serotonin breakdown. We found that serotonin directly signals to T cells to increase intracellular indole-3-acetaldehdye and inhibit mTOR activation, thereby promoting the differentiation of regulatory T cells, both ex vivo and in vivo in the neonatal intestine.

Ultra-low content physio-chemically crosslinked gelatin hydrogel improves encapsulated 3D cell culture.

Gelatin-based hydrogels are extensively used for 3D cell culture, bioprinting, and tissue engineering due to their cell-adhesive nature and tunable physio-chemical properties. Gelatin hydrogels for 3D cell culture are often developed using high-gelatin content (frequently 10-15 % w/v) to ensure fast gelation and improved stability. While highly stable, such matrices restrict the growth of encapsulated cells due to creating a dense, restrictive environment around the encapsulated cells.
