Multicenter Study
Current Practices of Intraventricular Antibiotic Therapy in the Treatment of Meningitis and Ventriculitis: Results from a Multicenter Retrospective Cohort Study.
Central nervous system (CNS) infections are particularly prevalent in the adult neurocritical care patient population and are associated with significant morbidity and mortality. Factors relevant to the nature of CNS infections pose significant challenges to clinicians treating afflicted patients. Intraventricular (IVT) administration of antibiotics may offer several benefits over systemic therapy; however, the outcomes and current practices of such treatments are poorly described in the literature. ⋯ Intraventricular antimicrobial agents resulted in a high CSF sterilization rate. Contemporary use of this route typically results in a treatment duration of less than a week. Prospective studies are needed to establish the optimal patient population, as well as the efficacy and safety of this route of administration.

Multicenter Study
Neurostereologic Lesion Volumes and Spreading Depolarizations in Severe Traumatic Brain Injury Patients: A Pilot Study.
Spreading depolarizations (SDs) occur in 50-60% of patients after surgical treatment of severe traumatic brain injury (TBI) and are independently associated with unfavorable outcomes. Here we performed a pilot study to examine the relationship between SDs and various types of intracranial lesions, progression of parenchymal damage, and outcomes. ⋯ These results suggest that subarachnoid and subdural blood are important primary injury factors in provoking SDs and that clustered SDs and parenchymal lesion expansion contribute independently to worse patient outcomes. These results warrant future prospective studies using detailed quantification of TBI lesion types to better understand the relationship between anatomic and physiologic measures of secondary injury.

The goal for this project was to develop a comprehensive set of common data elements (CDEs), data definitions, case report forms and guidelines for use in unruptured intracranial aneurysm (UIA) and subarachnoid hemorrhage (SAH) clinical research, as part of a new joint effort between the National Institute of Neurological Disorders and Stroke (NINDS) and the National Library of Medicine of the US National Institutes of Health. These UIA and SAH CDEs will join several other neurological disease-specific CDEs that have already been developed and are available for use by research investigators. ⋯ Dissemination and widespread use of CDEs can facilitate UIA and SAH clinical research and clinical trial design, data sharing, and analyses of observational retrospective and prospective data. It is vital to maintain an international and multidisciplinary collaboration to ensure that these CDEs are implemented and updated when new information becomes available.

Review Historical Article
Simulation in Neurocritical Care: Past, Present, and Future.
Simulation-based medical education is a technique that leverages adult learning theory to train healthcare professionals by recreating real-world scenarios in an interactive way. It allows learners to emotionally engage in the assessment and management of critically ill patients without putting patients at risk. Learners are encouraged to work at the edge of their expertise to promote growth and are provided with feedback to nurture development. ⋯ In contrast, other critical care educators have embraced the technique and built an impressive foundation of literature supporting its use. Slowly, neurocritical care educators have started experimenting with simulation-based medical education and sharing their results. In this review, we will investigate the historical origins of simulation in the neurosciences, the conceptual framework supporting the technique, current applications, and future directions.
