Review Meta Analysis
Detection of atrial fibrillation after ischemic stroke or transient ischemic attack: a systematic review and meta-analysis.
Atrial fibrillation (AF) confers a high risk of recurrent stroke, although detection methods and definitions of paroxysmal AF during screening vary. We therefore undertook a systematic review and meta-analysis to determine the frequency of newly detected AF using noninvasive or invasive cardiac monitoring after ischemic stroke or transient ischemic attack. ⋯ Detection of AF was highly variable, and the review was limited by small sample sizes and marked heterogeneity. Further studies are required to inform patient selection, optimal timing, methods, and duration of monitoring for detection of AF/paroxysmal AF.

Randomized Controlled Trial
Carotid stenting: is there an operator effect? A pooled analysis from the carotid stenting trialists' collaboration.
Randomized clinical trials show higher 30-day risk of stroke or death after carotid artery stenting compared with surgery. We examined whether operator experience is associated with 30-day risk of stroke or death in the Carotid Stenting Trialists' Collaboration database. ⋯ Carotid stenting should only be performed by operators with annual procedure volume ≥6 cases per year.

Randomized Controlled Trial
Early aphasia rehabilitation is associated with functional reactivation of the left inferior frontal gyrus: a pilot study.
Early poststroke aphasia rehabilitation effects and their functional MRI (fMRI) correlates were investigated in a pilot, controlled longitudinal study. ⋯ Early poststroke aphasia treatment is useful, has durable effects, and may lead to early enhanced recruitment of brain areas, particularly the left inferior frontal gyrus, which persists in the chronic phase.

The integrity of white matter tracts connecting different parts of the brain is important for rapid compensation for the lost function from ischemic stroke. Impaired white matter reserve capacity secondary to leukoaraiosis may facilitate detection of new symptomatic ischemic events that would otherwise remain inconspicuous after an initial ischemic stroke. We sought to identify whether the extent of leukoaraiosis was a predictor of risk of early stroke recurrence. ⋯ The extent of leukoaraiosis independently predicts 90-day recurrent stroke risk after ischemic stroke. This suggests that leukoaraiosis may be used for risk stratification in ischemic stroke.
