Randomized Controlled Trial
Relationship of White Matter Lesions with Intracerebral Hemorrhage Expansion and Functional Outcome: MISTIE II and CLEAR III.
Intracerebral hemorrhage (ICH) patients commonly have concomitant white matter lesions (WML) which may be associated with poor outcome. We studied if WML affects hematoma expansion (HE) and post-stroke functional outcome in a post hoc analysis of patients from randomized controlled trials. ⋯ http://www.clinicaltrials.gov trial-identifiers: NCT00224770 and NCT00784134.

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.

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.

Early systolic blood pressure (SBP) reduction is believed to improve outcome after spontaneous intracerebral hemorrhage (ICH), but there has been a limited assessment of SBP trajectories in individual patients. We aimed to determine the prognostic significance of SBP trajectories in ICH. ⋯ Our analyses suggest that in the first 6 h SBP reduction is significantly associated with the in-hospital outcome that varies with initial hematoma volume, and early SBP reduction > 40 mmHg may be harmful in ICH patients. For early SBP reduction to have an effective therapeutic effect, both target levels and optimum SBP reduction goals vis-à-vis hematoma volume should be considered.

Observational Study
Association of Cerebral Oximetry with Outcomes after Extracorporeal Membrane Oxygenation.
Extracorporeal membrane oxygenation (ECMO) is associated with neurologic morbidity and mortality. We investigated whether cerebral regional oxygen saturation (rSO2) is associated with neurologic outcomes and survival in children on ECMO. ⋯ Among children in one institution who underwent routine clinical rSO2 monitoring during ECMO, rSO2 decline was associated with unfavorable short-term neurologic outcome and death after adjusting for potential confounders. The effectiveness of initiating early preventative measures in these high-risk patients needs further study.
