Randomized Controlled Trial
Choice of ANesthesia for EndoVAScular Treatment of Acute Ischemic Stroke: Protocol for a randomized controlled (CANVAS) trial.
Background Observational studies indicate that the type of anesthesia, local or general, may be associated with the post-procedural neurological function in patients with acute ischemic stroke undergoing endovascular treatment. However, these results need further confirmation, and the causal relationship has not yet been established. Methods This is a randomized controlled equivalence trial. ⋯ The secondary endpoints are the peri-procedural mortality and morbidity. Discussion The study aims to determine the effects of anesthetic choice on neurological outcomes in patients with acute ischemic stroke undergoing intra-arterial recanalization. If the results are positive, the study will indicate that the type of anesthesia does not affect neurological outcome after endovascular treatment.

Background and purpose Although unclear-onset ischemic stroke, including wake-up ischemic stroke, is drawing attention as a potential target for reperfusion therapy, acute unclear-onset intracerebral hemorrhage has been understudied. Clinical characteristics, hematoma features, and outcomes of patients who developed intracerebral hemorrhage during sleep or those with intracerebral hemorrhage who were unconscious when witnessed were determined. Methods Consecutive intracerebral hemorrhage patients admitted within 24 hours after onset or last-known normal time were classified into clear-onset intracerebral hemorrhage and unclear-onset intracerebral hemorrhage groups. ⋯ There were fewer patients with modified Rankin Scale (mRS) scores of 0-2 (p = 0.033) and more patients with mRS scores of 5-6 (p = 0.009) and with fatal outcomes (p = 0.049) in unclear-onset intracerebral hemorrhage group compared with clear-onset intracerebral hemorrhage as crude values, but not after adjustment. Conclusions Patients with unclear-onset intracerebral hemorrhage presented with larger hematomas and higher National Institutes of Health Stroke Scale scores at emergent visits than those with clear-onset intracerebral hemorrhage, independent of underlying characteristics. Unclear-onset intracerebral hemorrhage patients showed poorer 30-day vital and functional outcomes than clear-onset intracerebral hemorrhage patients; these differences seem to be mainly due to initial hematoma volumes and National Institutes of Health Stroke Scale scores.

Randomized Controlled Trial Multicenter Study
Acute basilar artery occlusion: Endovascular Interventions versus Standard Medical Treatment (BEST) Trial-Design and protocol for a randomized, controlled, multicenter study.
Rationale Endovascular treatment plus standard medical therapy is superior to standard medical therapy alone for acute anterior proximal intracranial large artery occlusion strokes. The benefit of endovascular treatment in acute ischemic stroke caused by basilar artery occlusion remains unproven. Aim This study compares the safety and efficacy of endovascular treatment plus standard medical therapy versus standard medical therapy alone in acute ischemic stroke due to basilar artery occlusion. ⋯ The primary safety measure is mortality at 90 days. Trial registration ClinicalTrials.gov (NCT 02441556). Summary The BEST trial will provide valuable insights into the safety and efficacy of endovascular treatment for acute ischemic stroke patients with basilar artery occlusion.

Practice Guideline
Canadian Stroke Best Practice Recommendations: Telestroke Best Practice Guidelines Update 2017.
Every year, approximately 62,000 people with stroke and transient ischemic attack are treated in Canadian hospitals. The 2016 update of the Canadian Stroke Best Practice Recommendations Telestroke guideline is a comprehensive summary of current evidence-based and consensus-based recommendations appropriate for use by all healthcare providers and system planners who organize and provide care to patients following stroke across a broad range of settings. ⋯ Virtual rehabilitation therapies offer patients the opportunity to participate in rehabilitation therapies, supervised by physical and occupational therapists. While not without its limitations (e.g., access to telecommunications in remote areas, fragmentation of care), the evidence-to-date sets the foundation for improving access to care and management for patients during both the acute phase and now through post stroke recovery.

Observational Study
POST-NOAC: Portuguese observational study of intracranial hemorrhage on non-vitamin K antagonist oral anticoagulants.
Background There is a lower reported incidence of intracranial hemorrhage with non-vitamin K antagonist oral anticoagulants compared with vitamin K antagonist. However, the functional outcome and mortality of intracranial hemorrhage patients were not assessed. Aims To compare the outcome of vitamin K antagonists- and non-vitamin K antagonist oral anticoagulants-related intracranial hemorrhage. ⋯ Survival analysis adjusted for age, CHA2DS2VASc, HAS-BLED, and anticoagulation reversal revealed that non-vitamin K antagonist oral anticoagulants did not influence three-month mortality (hazard ratio (HR) = 0.83, 95% confidence interval (CI) = 0.39-1.80, p = 0.638). Multivariable ordinal regression for three-month functional outcome did not show a significant shift of modified Rankin Scale scores in non-vitamin K antagonist oral anticoagulants patients (odds ratio (OR) 1.26, 95%CI 0.55-2.87, p = 0.585). Conclusions We detected no significant differences in the three-month outcome between non-vitamin K antagonist oral anticoagulants- and vitamin K antagonists-associated intracranial hemorrhage, despite unavailability of non-vitamin K antagonist oral anticoagulants-specific reversal agents.
