Time From Imaging to Endovascular Reperfusion Predicts Outcome in Acute Stroke Clinical Sciences
Conclusions—Compared with target mismatch patients, those with the malignant profile experience faster infarct growth and a steeper decline in the odds of functional independence, with longer delays between baseline imaging and reperfusion. However, this does not exclude the possibility of treatment benefit in patients with a malignant profile.

Radiographic and Clinical Brain Infarcts in Cardiac and Diagnostic Procedures Clinical Sciences
Conclusions—One of 10 people with periprocedural RBIs during cardiac surgeries and invasive vascular diagnostic procedures resulted in strokes or transient ischemic attacks, which may serve as a potential surrogate marker of procedural proficiency and perhaps as a predictor of risk for periprocedural strokes.

Use of Platelet Function Testing Before Pipeline Embolization Device Placement Clinical Sciences
Conclusions—Clopidogrel nonresponders experienced a significantly higher rate of thromboembolic complications when compared with clopidogrel responders. However, this risk seems to be mitigated in nonresponders who were switched to ticagrelor or received a clopidogrel boost within 24 hours pre-procedure.

Symptomatic Carotid Occlusion Is Frequently Associated With Microembolization Clinical Sciences
Conclusions—Cerebral embolization plays an important role in the pathophysiology of ischemia in both carotid occlusion and stenosis, even among patients with watershed infarcts. The role of aggressive antithrombotic and antiplatelet therapy for symptomatic carotid occlusions may warrant further investigation given our findings.

Pathogenesis and Risk Factors for Cerebral Infarct After Surgical Aortic Valve Replacement Brief Reports
Conclusions— The principal mechanism of acute cerebral infarction after aortic valve replacement is embolism. There are distinct factors associated with watershed and embolic infarct, some of which may be modifiable.

Clinical and Procedural Predictors of Outcomes From the Endovascular Treatment of Posterior Circulation Strokes Clinical Sciences
Conclusions— Time to the start of the procedure is an important predictor of clinical success after thrombectomy in patients with posterior circulation strokes. Both stent retriever and aspiration thrombectomy as primary treatment approaches are effective in achieving successful recanalization.

Pediatric Cortical Vein Thrombosis: Frequency and Association With Venous Infarction Brief Reports
Conclusions— In our cohort, CVT was significantly associated with seizures at presentation, hemorrhage and restricted diffusion on acute imaging, as well as neurological disability and venous infarction at follow-up. Involvement of cortical veins in cerebral sinovenous thrombosis is associated with an increased risk of infarction and adverse outcome in children.

Predictors of Finding Occult Atrial Fibrillation After Cryptogenic Stroke Clinical Sciences
Conclusions— Mobile cardiac outpatient telemetry detects AF in a substantial proportion of cryptogenic stroke patients. Age >60 years and radiographic evidence of prior cortical or cerebellar infarction are robust indicators of occult AF. Patients with neither had a low prevalence of AF.

Safety and Effect of Metoclopramide to Prevent Pneumonia in Patients With Stroke Fed via Nasogastric Tubes Trial Clinical Sciences
Conclusions— This study suggests that metoclopramide may reduce the rate of pneumonia and may improve other clinical outcomes in patients with subacute stroke fed via nasogastric tube. These findings need to be confirmed in larger randomized and blinded trials. Clinical Trial Registration— URL: https://www.clinicaltrialsregister.eu.

Impaired Cerebral Autoregulation Is Associated With Vasospasm and Delayed Cerebral Ischemia in Subarachnoid Hemorrhage Clinical Sciences
Conclusions— Dynamic cerebral autoregulation is impaired in the early days after SAH. Including autoregulation as part of the initial clinical and radiographic assessment may enhance our ability to identify patients at a high risk for developing secondary complications after SAH.

Prospective, Randomized, Open-Label Phase II Trial on Concomitant Intraventricular Fibrinolysis and Low-Frequency Rotation After Severe Subarachnoid Hemorrhage Clinical Sciences
Conclusions— Despite the ineffectiveness on reduction of delayed cerebral ischemia or poor functional outcome, intraventricular fibrinolysis and kinetic therapy seems to be a safe and effective concept for therapeutic reduction of subarachnoid clot in a patient collective experiencing predominately severe subarachnoid hemorrhage. Therefore, future studies should investigate this treatment in a larger patient collective with a lower degree of primary brain injury and until full clot clearance on serial imaging.
