Recent prospective registration studies of transient ischemic attack in Western countries demonstrated that large artery atherosclerosis is the highest risk etiology for early stroke recurrence under urgent evaluation and treatment. On the other hand, some limited transient ischemic attack studies from East Asian countries showed transient ischemic attack patients due to small vessel occlusion were at a higher early stroke risk. ⋯ Small vessel occlusion-transient ischemic attack, especially with acute small deep infarct, had a higher early stroke risk compared with other etiologies in Japanese transient ischemic attack patients who received early management.

Randomized Controlled Trial
Branch atheromatous disease diagnosed as embolic stroke of undetermined source: A sub-analysis of NAVIGATE ESUS.
Branch atheromatous disease (BAD) is distinctive from large and small arterial diseases, which is single subcortical infarction larger than lacunar stroke in the territories of deep perforators without relevant arterial stenosis. BAD meets the current criteria of embolic stroke of undetermined source. We performed an exploratory analysis of BAD in patients recruited to NAVIGATE embolic stroke of undetermined source, a randomized controlled trial to compare rivaroxaban and aspirin in embolic stroke of undetermined source patients. ⋯ BAD was relatively common, especially in Asian and from Eastern Europe among embolic stroke of undetermined source patients. Stroke severity was higher at randomization but recurrence of stroke was fewer in BAD than non-BAD patients. The efficacy and safety of rivaroxaban and aspirin did not differ among BAD patients.

Randomized Controlled Trial Multicenter Study
The randomized study of endovascular therapy with versus without intravenous tissue plasminogen activator in acute stroke with ICA and M1 occlusion (SKIP study).
Bridging therapy with endovascular therapy (EVT) and intravenous thrombolysis (IVT) has been reported to improve outcomes for acute stroke patients with large-vessel occlusion in the anterior circulation. While the IVT may increase the reperfusion rate, the risk of hemorrhagic complications increases. Whether EVT without IVT (direct EVT) is equally effective as bridging therapy in acute stroke remains unclear. ⋯ This trial may help determine whether direct EVT should be recommended as a routine clinical strategy for ischemic stroke patients within 4.5 h from onset. Direct EVT would then become the choice of therapy in stroke centers with endovascular facilities.

Randomized Controlled Trial Multicenter Study
The Acute Stroke or Transient Ischemic Attack Treated with Ticagrelor and Aspirin for Prevention of Stroke and Death (THALES) trial: Rationale and design.
In patients with acute cerebral ischemia, the rate of stroke, myocardial infarction, or death during 90 days was reported to be non-significantly lower with ticagrelor compared with aspirin, with no increase in major hemorrhage. Dual antiplatelet therapy may be more effective in this setting. ⋯ http://www.clinicaltrials.gov . Unique identifier: NCT03354429.

There is evidence that racial and ethnic differences among intracerebral hemorrhage (ICH) patients exist. We sought to establish the occurrence of disparities in hospital utilization in the United States. ⋯ Minorities had greater utilization of lifesaving and life sustaining procedures, and longer LOS. Whites had greater utilization of palliative care, hospice, and higher in-hospital mortality. These results may reflect differences in culture or access to care and deserve further study.
