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.

We aimed to investigate the feasibility, preliminary safety, and efficacy of prolonged low-dose intravenous thrombolysis in posterior circulation stroke patients with a thrombus lodged in the basilar artery who were ineligible for standard rtPA administration. ⋯ Prolonged low-dose thrombolysis with rtPA may be considered as individual treatment option in selected high-risk patients with basilar artery thrombosis. Presented data may lay the groundwork to further investigate safety and efficacy in a prospective trial.

Our goal was to perform a systematic review of the literature on the use of ketamine in traumatic brain injury (TBI) and its effects on intracranial pressure (ICP). All articles from MEDLINE, BIOSIS, EMBASE, Global Health, HealthStar, Scopus, Cochrane Library, the International Clinical Trials Registry Platform (inception to November 2013), reference lists of relevant articles, and gray literature were searched. Two reviewers independently identified all manuscripts pertaining to the administration of ketamine in human TBI patients that recorded effects on ICP. ⋯ No significant adverse events related to ketamine were recorded in any of the studies. Outcome data were poorly documented. There currently exists Oxford level 2b, GRADE C evidence to support that ketamine does not increase ICP in severe TBI patients that are sedated and ventilated, and in fact may lower it in selected cases.

In patients with aneurysmal subarachnoid hemorrhage (aSAH), it is unclear whether aneurysm treatment <24 h after ictus results in better outcomes than treatment 24-72 h after aSAH. We studied whether aneurysm occlusion <24 h is associated with better outcomes than occlusion 24-72 h after aSAH. ⋯ Our results suggest that aneurysm occlusion can be performed in day time within 72 h after ictus, instead of on an emergency basis. However, due to the retrospective, non-randomized design of our study, our results cannot be considered as definitive evidence.
