Stroke is a leading cause of disability and death worldwide. The best estimates local, national, global burden stroke are derived from prospective population-based studies. We aimed to investigate the incidence, risk factors, long-term prognosis, care, quality life after in Ñuble region Chile.We did community-based study with use multiple overlapping sources hospitalised, ambulatory, deceased cases. Standardised diagnostic criteria were used identify follow up all cases occurring resident...
Background The uptake of proven stroke treatments varies widely. We aimed to determine the association evidence‐based processes care for acute ischemic ( AIS ) and clinical outcome patients who participated in HEADPOST (Head Positioning Acute Stroke Trial), a multicenter cluster crossover trial lying flat versus sitting up, head positioning stroke. Methods Results Use 8 were considered: reperfusion therapy eligible patients; unit care; antihypertensive, antiplatelet, statin, anticoagulation...
To determine the optimal cut point on NIH Stroke Scale (NIHSS) for predicting poor 90-day clinical outcome in patients with supratentorial and infratentorial acute ischemic stroke (AIS).Data are from participants of alteplase-dose arm randomized controlled trial, Enhanced Control Hypertension Thrombolysis Study (ENCHANTED). Associations between baseline characteristics clinically defined AIS functional outcome, by scores 3-6 modified Rankin Scale, were evaluated logistic regression models,...

Clinical ethics support services (CESS) have been developing worldwide with growing interest in evaluating their quality. Paediatric-specific CESSs (p-CESS) received little attention, and evidence from adult might not be generalisable. Evidence on service models practices is crucial to inform further research debate quality evaluation minimum standards for p-CESSs. We aim systematically identify, appraise synthesise p-CESS structures, processes outcomes.
