Management of stroke patients in the acute setting is a high-stakes task with several challenges including the need for rapid assessment and treatment, maintenance of high-performing team dynamics, management of cognitive load affecting providers, and factors impacting team communication. Crisis resource management (CRM) provides a framework to tackle these challenges and is well established in other resuscitative disciplines. The current Coronavirus Disease 2019 (COVID-19) pandemic has exposed a potential quality gap in emergency preparedness and the ability to adapt to emergency scenarios in real time. ⋯ As stroke care processes evolve during these trying times, the importance of consistent, safe, and efficacious care facilitated by CRM principles offers a unique avenue to alleviate human factors and support high-performing teams.

Desmopressin (DDAVP) has been suggested for antiplatelet medication reversal in patients with traumatic brain injury (TBI) but there are limited data describing its effect on clinical outcomes. The purpose of this study was to evaluate the effect of DDAVP on hematoma expansion and thrombosis in patients with TBI who were prescribed pre-injury antiplatelet medications. ⋯ DDAVP was associated with a lower incidence of hematoma expansion in patients with mild TBI who were prescribed pre-injury antiplatelet medications. These results justify a randomized controlled trial to further evaluate the role of DDAVP for this indication.

Large hemispheric infarction (LHI) is an ischemic stroke affecting at least two-thirds of the middle cerebral artery territory, with or without involvement of the anterior cerebral artery or posterior cerebral artery, and approximately 77% of LHI patients have early consciousness disorder (ECD). We constructed a functional brain network for LHI patients with an acute consciousness disorder to identify new diagnostic markers related to ECDs by analyzing brain network characteristics and mechanisms. ⋯ In patients with LHI, higher levels of consciousness were associated with more alpha and beta oscillations and fewer delta and theta oscillations. Higher ApEn, PeEn, total brain connectivity, and small-worldness and a wider signal distribution range corresponded to a higher consciousness level.

Mitochondrial dysfunction is related to brain ischemic injury and neural cell death. However, little is known about the association between mitochondrial dysfunction of cerebrospinal fluid (CSF) and delayed cerebral ischemia (DCI) following subarachnoid hemorrhage (SAH). The objective of this study was to investigate whether extracellular CSF mitochondria might serve as a potential biomarker for DCI. ⋯ Mitochondrial membrane potential could be a marker of DCI. JC-1 ratios seemed to be able to predict future DCI onset. Further studies are needed to determine detailed mechanisms of extracellular mitochondria-mediated cell-to-cell signals in DCI.
