Traumatic brain injury (TBI) is a major cause of morbidity and mortality in the United States. Older adults represent an understudied and growing TBI population. Current Brain Trauma Foundation guidelines support prophylactic antiseizure medication (ASM) administration to reduce the risk of early posttraumatic seizures (within 7 days of injury) in patients with severe TBI. Whether ASM decreases mortality or early seizure risk in this population remains unclear. This study addresses the knowledge gap regarding the impact of ASM administration on the risk of seizure or mortality after TBI in patients more than 65 years of age. ⋯ Early ASM administration was associated with reduced mortality at 7 days, 30 days, and 1 year but did not decrease the risk of early seizures among older adults who presented with TBI at an ICU. This benefit was observed in mild, moderate, and severe TBI assessed by Glasgow Coma Score on presentation among patients 65 years old and older and suggests broader recommendations for the use of ASM in older adults who present with TBI of any severity at an ICU.

Multicenter Study Observational Study
Association Between Serum Albumin and Hospital-Acquired Infections After Aneurysmal Subarachnoid Hemorrhage.
Low serum albumin levels have been identified as a predictor of infectious complications in critically ill patients. However, the association in patients with aneurysmal subarachnoid hemorrhage (aSAH) remains unclear. We aimed to evaluate the prognostic value of hypoalbuminemia using blood samples at admission in patients with aSAH. ⋯ In this large study of matched patients with aSAH, hypoalbuminemia at admission was associated with hospital-acquired infections. A decrease in serum albumin levels within 72 h of admission was associated with higher hospital-acquired infections.

Quantitative analysis of ventricular cerebrospinal fluid (vCSF) proteins following acute brain injury (ABI) may help identify pathophysiological pathways and potential biomarkers that can predict unfavorable outcome. ⋯ Dysregulated vCSF protein expression after ABI may be associated with an increased risk of severe ICH and death.

Previous studies suggest that case mortality of aneurysmal subarachnoid hemorrhage (aSAH) has decreased during the last decades, but most studies have been unable to assess case severities among individual patients. We aimed to assess changes in severity-adjusted aSAH mortality in patients admitted to intensive care units (ICUs). ⋯ Between 2003 and 2019, patients with aSAH admitted to ICUs became older and the proportion of less severe cases increased. Unadjusted mortality decreased but age and case severity adjusted-mortality remained unchanged.

Brain death (BD), the irreversible cessation of function in the whole brain, is a well-known condition in most countries. The criteria and practical guidelines for brain death determination (BDD) in China were issued by the Brain Injury Evaluation Quality Control Center (BQCC) of the National Health and Family Planning Commission in 2013. Thereafter, we proposed a plan called the three-step quality control plan (three-step QCP) to ensure the safety and consistency of the clinical judgments regarding BD. By retrospectively reviewing this plan, we aimed to identify problems during its implementation and to provide suggestions for future work on quality control for BDD. ⋯ The three-step QCP is of significant utility for ensuring accuracy and appropriateness in BDD. Simultaneously, this study provides important evidence for advancing quality control for BDD in the next stage.
