Economic and Societal Aspects of Stroke Management
Stroke is a major health burden worldwide with attendant mortality, morbidity, and cost. In 2010, there were approximately 16.9 million strokes and an estimated 33 million stroke survivors worldwide. Also, in the United States, stroke is the third leading cause of death, with ischemic stroke resulting in 8% 30-day mortality (20% for hemorrhagic stroke). The staggering economic cost of the disease is driven largely by disability and long term care. Efforts in stroke healthcare delivery are focusing on performance, efficiency and value to better serve the consumer.

Artificial Intelligence and Acute Stroke Imaging ADULT BRAIN
SUMMARY: Artificial intelligence technology is a rapidly expanding field with many applications in acute stroke imaging, including ischemic and hemorrhage subtypes. Early identification of acute stroke is critical for initiating prompt intervention to reduce morbidity and mortality. Artificial intelligence can help with various aspects of the stroke treatment paradigm, including infarct or hemorrhage detection, segmentation, classification, large vessel occlusion detection, Alberta Stroke Program Early CT Score grading, and prognostication. In particular, emerging artificial intelligence techniques such as convolutional ne...

Outcomes of wake-up stroke undergoing mechanical thrombectomy: A systematic review and meta-analysis
CONCLUSION: Mechanical thrombectomy for patients with wake-up stroke was found to have favorable rates of good functional outcomes and relatively low rates of adverse events.PMID:36254575 | DOI:10.1177/15910199221133167

Recanalization with Stent-Retriever Devices in Patients with Wake-Up Stroke INTERVENTIONAL
CONCLUSIONS: Despite successful and rapid recanalization with stent-retriever devices, good clinical outcome in patients with wake-up stroke is achieved in a minority of patients. Clinical outcome remains poor. Bleeding rates were higher compared with recanalization procedures within 6 hours after stroke onset.

Association of CT Perfusion Parameters with Hemorrhagic Transformation in Acute Ischemic Stroke EDITOR'S CHOICE
CONCLUSIONS: Of the examined CTP parameters, only lower rCBV was found to be significantly associated with a relatively higher chance of hemorrhagic transformation.

Clinical and Angiographic Features and Stroke Types in Adult Moyamoya Disease FELLOWS' JOURNAL CLUB
CONCLUSIONS: In adult Moyamoya disease, major artery occlusion and collateral compensation occurred more often in the hemorrhagic than in the ischemic hemispheres. Thus, anterior cerebral artery occlusion with or without MCA occlusion and intracranial aneurysms may be the main contributing factors to hemorrhagic stroke in adult patients with Moyamoya disease.

Efficacy of systemic thrombolysis within 4.5 h from stroke symptom onset: a single-centre clinical and diffusion–perfusion 3T MRI study
Conclusion Treatment with IV rt-PA within 4.5 h of stroke onset preserves a significant amount of brain tissue from final infarction, and increases the possibility of early and late clinical improvement.

Conscious Sedation versus General Anesthesia during Endovascular Acute Ischemic Stroke Treatment: A Systematic Review and Meta-Analysis EVIDENCE-BASED MEDICINE LEVEL 1
CONCLUSIONS: Patients with acute ischemic stroke undergoing intra-arterial therapy may have worse outcomes with general anesthesia compared with conscious sedation. However, the difference in stroke severity at the onset may confound the comparison in the available studies; thus, a randomized trial is necessary to confirm this association.

The Modern Clinical Neuroimager: Leading the Next Generation in Stroke
ABSTRACT The recent culmination of imaging‐endowed endovascular stroke trials has decisively proven the utility of clinically relevant neuroimaging in improving the outcome of patients with potentially debilitating neurological disorders. These large multicenter trials conducted across several continents notably utilized a variety of multimodal CT/MRI modalities to rapidly identify a favorable collateral profile that presages clinically beneficial revascularization. The modern clinical neuroimager may accelerate complex decision‐making through the rational use of a variety of imaging modalities and an active feedback l...

Outcomes Are Not Different between Patients with Intermediate and High DWI-ASPECTS after Stent-Retriever Embolectomy for Acute Anterior Circulation Stroke INTERVENTIONAL
CONCLUSIONS: Our study suggested that there were no differences in outcomes between patients with a high DWI-ASPECTS and those with an intermediate DWI-ASPECTS who underwent stent-retriever embolectomy for acute anterior circulation stroke. Thus, patients with an intermediate DWI-ASPECTS otherwise eligible for endovascular therapy may not be excluded from stent-retriever embolectomy or stroke trials.

Topographic Assessment of Acute Ischemic Changes for Prognostication of Anterior Circulation Stroke
CONCLUSIONSTopographic assessment of acute ischemic changes using the sASPECTS (including caudate, lentiform nucleus, insula, and M5) can predict disability/death in anterior circulation stroke as accurately as the ASPECTS; and may help predict response to treatment and risk of developing symptomatic ICH.
