Rates and Determinants of 5-Year Outcomes After Atrial Fibrillation-Related Stroke: A Population Study Clinical Sciences

Background and Purpose— Demographic trends in atrial fibrillation (AF) incidence may yield a substantial rise in the societal burden of AF-related stroke (AF-stroke). Accurate population-wide outcome data are essential to inform health service planning to improve AF-stroke prevention, and provision of rehabilitation, nursing home, and community supports for AF-stroke survivors. Methods— We investigated rates and determinants of 5-year fatality, stroke recurrence, functional outcomes, and prescribing of secondary prevention medications in AF-stroke in the North Dublin Population Stroke Study. Ascertainment included hot and cold pursuit using multiple overlapping sources. Survival analysis was performed using lifetables and Kaplan–Meier survival curves, and Cox proportional hazard modeling was performed to identify predictors of death and recurrent stroke. Results— Five hundred sixty-eight patients with new stroke were identified, including 177 (31.2%) AF-stroke. At 5 years, 39.2% (confidence interval, 31.5–46.8) of ischemic AF-stroke patients were alive. Congestive heart failure, hypertension, age

This study aimed to investigate the effects of hirudin on the production of extracellular matrix (ECM) factors by renal tubular epithelial cells in a rat model of diabetic kidney disease (DKD) and HK-2 human renal tubule epithelial cells. MATERIAL AND METHODS Sprague-Dawley rats were divided into the normal control group (n=10), the normal control+hirudin group (n=10), the DKD model group (n=12) and the DKD+hirudin group (n=12). At the end of the study, renal histopathology was undertaken, and the expression of type IV collagen, fibronectin, hypoxia-inducible factor-1alpha (HIF-1alpha), and vascular endothelial growth fact...

One commonly reported phenomenon in the first months of the Covid-19 era in the United States has been the reduction in emergency department (ED) visits and hospitalizations of patients with heart attacks, strokes and other acute, non-Covid illnesses [1]. Less is known about whether and how the number of patients presenting to EDs for psychiatric problems has changed.
