Conclusions: These findings suggest that TMBs may serve as a uniquely persistent indicator of TBI and reinforce the importance of acute post-injury imaging for accurate characterization of persistent imaging findings. PMID: 32228304 [PubMed - as supplied by publisher]
Authors: Teng F, Yin Y, Guo J, Jiang M Abstract Calpain activation may have an important role in early brain injury (EBI) following subarachnoid hemorrhage (SAH). The present study investigated the effects of the calpastatin peptide, a cell-permeable peptide that functions as a potent inhibitor of calpain, on EBI in a rat SAH model. It was revealed that calpastatin peptide treatment significantly reduced SAH-induced body weight loss and neurological deficit at 72 h when compared with untreated SAH controls. Furthermore, the quantification of brain water content and the extravasation of Evans blue dye revealed a sig...
ConclusionsStroke or stroke-like syndrome of infectious origin can be observed in an important proportion of case presenting with sensory-motor deficit of unknown origin; their accurate diagnosis has a considerable impact in terms of treatment choices and outcome.
ConclusionThis propensity score analysis demonstrated that the EVT patients with acute ICAD-related MCA M1 occlusion had similar angiographic and clinical outcomes compared to those with M1 embolism on a similar baseline condition.
CONCLUSIONS: Given the trend toward expedited treatment of acute ischemic stroke with subsequent transfer to regional referral centers, vascular specialists will be confronted with an increasing number of patients who may require urgent CEA after antecedent IVT. Further study is warranted to clearly delineate the appropriate interval from IVT to CEA and, specifically, to establish the safety of CEA with 72 hours of tPA administration.

This study aimed to investigate pump position, derived from chest X-rays of HM3 patients, in correlation to any neurological dysfunction (ND) and specifically to ischemic stroke (IS) and intracranial hemorrhage (ICH).
CONCLUSIONS The present study demonstrated that wogonoside prevents brain edema development and apoptosis of neurons in rats by promoting SIRT1 expression and suppression of p53 activation. Therefore, wogonoside has therapeutic potential for the treatment of edema and needs to be investigated further to completely define the mechanism involved. PMID: 32221271 [PubMed - in process]
Abstract INTRODUCTION: Stroke is a leading cause of death and disability, with the administration of reverse transcriptase-plasminogen activator (rtPA) improving outcomes in a time-dependent manner. Only 52.3% of our eligible stroke patients received rtPA within 60 minutes of arrival. We aimed to better the percentage of acute stroke patients receiving rtPA within 60 minutes of arrival at the emergency department (ED). METHODS: Results from the first year of a clinical practice improvement project, where quality improvement interventions were implemented, are presented. Primary outcome measure was percentage ...
Moyamoya disease is a cerebrovascular disease of unknown origin causing progressive stenosis of the intracranial arteries in the circle of Willis.1,2 Stenoocclusive lesions and the subsequent hemodynamic compromise result in the formation of dilated, fragile collateral vessels at the base of the brain, which are termed moyamoya vessels. The presentation of patients with these lesions varies from asymptomatic to symptoms of headache, epilepsy, and ischemic and hemorrhagic stroke. Patients with moyamoya disease sometimes have concomitant extracranial arterial stenosis3; of all the extracranial arteries reported, the most com...
