Multicenter Study Observational Study
Individualized Thresholds of Hypoxemia and Hyperoxemia and their Effect on Outcome in Acute Brain Injured Patients: A Secondary Analysis of the ENIO Study.
In acute brain injury (ABI), the effects of hypoxemia as a potential cause of secondary brain damage and poor outcome are well documented, whereas the impact of hyperoxemia is unclear. The primary aim of this study was to assess the episodes of hypoxemia and hyperoxemia in patients with ABI during the intensive care unit (ICU) stay and to determine their association with in-hospital mortality. The secondary aim was to identify the optimal thresholds of arterial partial pressure of oxygen (PaO2) predicting in-hospital mortality. ⋯ In patients with ABI, hypoxemia and mild/moderate hyperoxemia were relatively frequent. Hypoxemia and hyperoxemia during ICU stay may influence in-hospital mortality. However, the small number of oxygen values collected represents a major limitation of the study.

Randomized Controlled Trial Multicenter Study
Clinician-Reported Physical and Cognitive Impairments After Convulsive Status Epilepticus: Post Hoc Study of a Randomized Controlled Trial.
Clinician-reported outcome (ClinRO) measures are emerging as useful contributors to assessments of treatment benefits. The objective of this study was to collect ClinRO measures of physical and cognitive impairments after convulsive status epilepticus (CSE) requiring intensive care unit admission. ⋯ In patients attending the in-person neurologist visit on day 90 after CSE onset, ClinRO measures indicated that the main impairments were cognitive. FIM and MMSE scores were associated with GOS scores. Further studies are needed to evaluate the possible impact of neuroprotective and rehabilitation strategies on disability and cognitive impairments in survivors of CSE. Clinical trial registration NCT01359332.

Clinical observations indicated that vaccine-induced immune thrombosis with thrombocytopenia (VITT)-associated cerebral venous sinus thrombosis (CVST) often has a space-occupying effect and thus necessitates decompressive surgery (DS). While comparing with non-VITT CVST, this study explored whether VITT-associated CVST exhibits a more fulminant clinical course, different perioperative and intensive care unit management, and worse long-term outcome. ⋯ Although the prediction of individual courses remains challenging, DS should be considered early in VITT-associated CVST because an overall favorable outcome appears achievable in these patients.

Multicenter Study
Neurologic Complications in Critically Ill Patients with Toxic Alcohol Poisoning: A Multicenter Population-Based Cohort Study.
Toxic alcohol poisoning is regularly encountered in emergency departments and intensive care units (ICUs). Most patients present with an altered level of consciousness, but the subsequent course and spectrum of neurologic complications and outcomes is highly variable. ⋯ Methanol overdose is the most common form of toxic alcohol poisoning to result in ICU admission. Poor neurologic outcomes may occur especially with methanol poisoning, with more than one in five patients dying or having persistent cognitive or visual impairment. A wide anion gap independently predicts poor outcome, emphasizing the importance of expeditious recognition and treatment.
