Sleep quality and duration as predictors of alcohol and cannabis use motives in daily life.

Objective: Alcohol and cannabis are two of the most widely used substances in the United States, where sleep problems are also prominent. Although poor sleep is linked to substance use, little is known about how prior-night sleep contributes to next-day decisions to use substances in daily life. This study tested the impact of prior-night sleep duration and quality on momentary motives for alcohol (Aim 1) and cannabis use (Aim 2).

Expert consensus on the benefits of neuraminidase in conventional influenza vaccines: a Delphi study.

Background: Seasonal vaccination is the mainstay of human influenza prevention. Licensed influenza vaccines are regularly updated to account for viral mutations and antigenic drift and are standardised for their haemagglutinin content. However, vaccine effectiveness remains suboptimal.

TDP43 autoregulation gives rise to dominant negative isoforms that are tightly controlled by transcriptional and post-translational mechanisms.

The nuclear RNA-binding protein TDP43 is integrally involved in the pathogenesis of amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD). Previous studies uncovered N-terminal TDP43 isoforms that are predominantly cytosolic in localization, prone to aggregation, and enriched in susceptible spinal motor neurons. In healthy cells, however, these shortened (s)TDP43 isoforms are difficult to detect in comparison to full-length (fl)TDP43, raising questions regarding their origin and selective regulation.

Long-term performance and stability of implanted neural interfaces in individuals with lower limb loss.

Objective: High-density nerve cuffs have been successfully utilized to restore somatosensation in individuals with lower-limb loss by interfacing directly with the peripheral nervous system. Elicited sensations via these devices have improved various functional outcomes, including standing balance, walking symmetry, and navigating complex terrains. Deploying neural interfaces in the lower limbs of individuals with limb loss presents unique challenges, particularly due to repetitive muscle contractions and the natural range of motion in the knee and hip joints for transtibial and transfemoral amputees, respectively.

The prevalence of obesity in children with CHD: what has changed over the past decade in Southwestern Ontario?

Objective: To assess the prevalence of obesity and investigate any changes in body mass index in children with CHD compared to age-matched healthy controls, in Southwestern Ontario.

Methods: The body mass index z-scores of 1259 children (aged 2-18) with CHD were compared with 2037 healthy controls. The body mass index z-scores of children who presented to our paediatric cardiology outpatient clinic from 2018 to 2021 were compared with previously collected data from 2008 to 2010.
