Ultraprocessed Food Intake and Adiposity, Vascular Brain Injury, and Cognition in Middle-Aged Adults

Importance Ultraprocessed foods (UPFs) account for a substantial and increasing proportion of dietary intake in Canada. Although UPFs are consistently associated with adiposity and cardiometabolic disease, their associations with subclinical vascular brain injury (VBI) and cognit...

Chronotherapeutic considerations for antiplatelet therapy in cardiovascular risk prevention – A systematic review

Summary: Background: Cardiovascular physiology exhibits circadian rhythms, including a morning surge in platelet reactivity and cardiovascular events. Aligning the timing of antiplatelet therapy with these rhythms may be a simple, cost-effective approach to improve clinical effic...

International Modified Delphi Consensus on Assessment and Management of Covert Brain Infarction

BackgroundCovert brain infarction (CBI) is a frequent incidental neuroradiological finding increasingly recognized as clinically relevant due to its association with stroke, cognitive decline, and other adverse outcomes. However, substantial uncertainty remains regarding its opti...

Intersectionality in HIV-related policy documents affecting people who use drugs in Ontario, Canada: a policy document analysis

In 2023 Canadian surveillance data, injection drug use accounted for 13.6% of new HIV diagnoses among males and 28.4% among females in exposure-category data. This study identified the presence of intersectionality language among health policies that affect access to HIV related...

Pharmacological Management of Opioid Use Disorder: A Systematic Review and Network Meta-Analysis: Prise en charge pharmacologique du trouble de l'usage des opiacés : revue systématique et méta-analyse en réseau

Objective To assess the comparative benefits and harms of opioid substitution and antagonist therapies (OSATs) for opioid use disorder (OUD) using a network meta-analysis (NMA) of randomized controlled trials (RCTs). Data Sources Medline, EMBASE, PubMed, PsycINFO, Web of Science,...

Non‐contrast CT Markers of Hematoma Expansion and Andexanet Response in Factor Xa Inhibitor‐Associated Intracerebral Hemorrhage: An Analysis from ANNEXa ‐I Trial

In this post hoc analysis of the ANNEXa-I trial (n = 434), we evaluated non-contrast computed tomography (NCCT) markers of hematoma expansion (HE) in factor Xa inhibitor (FXai) -associated intracerebral hemorrhage (ICH). At least one NCCT marker was present in 72.1%, and HE (≥12....

Cross-sectional evaluation of anthropometric measures vs MRI-measured visceral and hepatic fat in a Canadian cohort

Abstract Context Accurate assessment of excess body fat and its cardiometabolic risk is essential in clinical and epidemiologic research. Body mass index (BMI), although widely used, does not capture visceral or ectopic fat. Objective To evaluate how anthropometric measures—BMI,...

Putting Globus Into Context: Prevalence, Characteristics, and Overlap With Other Disorders of Gut‐Brain Interaction

OBJECTIVE: Globus is characterized by the sensation of a lump in the throat without dysphagia or underlying structural abnormality or major motility disorder. Reported prevalences vary considerably across studies. Globus has been linked to both heartburn and affective disorders....

Serum Glial Fibrillary Acidic Protein Dynamics, Disease Progression, and Therapy Response in Multiple Sclerosis

Importance: Capturing individual multiple sclerosis (MS) progression is difficult; few studies have evaluated glial fibrillary acidic protein (GFAP) in large longitudinal cohorts with independent validation. Objective: To investigate whether serum GFAP levels and treatment-relate...
