Severe middle cerebral artery stroke (MCA) is associated with a high rate of morbidity and mortality. We assessed the hypothesis that patient-specific variables may be associated with outcomes. We also sought to describe under-recognized patient-centered outcomes. ⋯ Adverse outcomes after severe stroke are common. Concurrent ACA involvement predicts mortality in severe MCA stroke. It is useful to understand the incidence of life-sustaining procedures, such as tracheostomy and gastrostomy, as well as factors that contribute to their necessity.

DESTINY-S: Attitudes of Physicians Toward Disability and Treatment in Malignant MCA Infarction.
Decompressive hemicraniectomy (DHC) reduces mortality and improves outcome after malignant middle cerebral artery (MCA) infarction but leaves a high number of survivors severely disabled. Attitudes among physicians toward the degree of disability that is considered acceptable and the impact of aphasia may play a major role in treatment decisions. ⋯ Little consensus exists among physicians regarding acceptable outcome and therapeutic management after malignant MCA infarction, and physician's recommendations do not correlate with available evidence. We advocate for a decision-making process that balances scientific evidence, patient preference, and clinical expertise.

Malignant infarction is characterized by the formation of cerebral edema, and medical treatment is limited. Preclinical data suggest that glyburide, an inhibitor of SUR1-TRPM4, is effective in preventing edema. We previously reported feasibility of the GAMES-Pilot study, a two-center prospective, open label, phase IIa trial of 10 subjects at high risk for malignant infarction based on diffusion weighted imaging (DWI) threshold of 82 cm(3) treated with RP-1127 (glyburide for injection). In this secondary analysis, we tested the hypothesis that RP-1127 may be efficacious in preventing poor outcome when compared to controls. ⋯ In this pilot study, RP-1127-treated subjects showed better clinical outcomes when compared to historical controls. An adequately powered and randomized phase II trial of patients at risk for malignant infarction is needed to evaluate the potential efficacy of RP-1127.

The Glasgow Coma Scale (GCS) is a routine component of a neurological exam for critically ill traumatic brain injury (TBI) patients, yet has been criticized for not accurately depicting verbal status among intubated patients or including brain stem reflexes. Preliminary research on the Full Outline of UnResponsiveness (FOUR) Scale suggests it overcomes these limitations. Research is needed to determine correlations with patient outcomes. The aims of this study were to: (1) examine correlations between 24 and 72 h FOUR and GCS scores and functional/cognitive outcomes; (2) determine relationship between 24 and 72 h FOUR scores and mortality. ⋯ FOUR is comparable to GCS in terms of predictive ability for functional status, cognitive outcome 3 months post-injury, and in-hospital mortality.
