Meta Analysis
Beta-Blockade in Aneurysmal Subarachnoid Hemorrhage: a Systematic Review and Meta-Analysis.
Sympathetic nervous system activation after aneurysmal subarachnoid hemorrhage (aSAH) is associated with complications and poor outcome. In this systematic review and meta-analysis, we investigate the effect of beta-blockers on outcome after aSAH. ⋯ In adult patients with aSAH, beta-blocker therapy is associated with a mortality benefit. Studies are generally of a low quality with considerable clinical heterogeneity. Prospective large interventional trials with patient centered outcomes are required to validate this finding.

Hypernatremia has been associated with mortality in neurocritically ill patients, with and without traumatic brain injury (TBI). These studies, however, lack concomitant adjustment for hyperchloremia as a physiologically co-occurring finding despite the associations with hyperchloremia and worse outcomes after trauma, sepsis, and intracerebral hemorrhage. The objective of our study was to examine the association of concomitant hypernatremia and hyperchloremia with in-hospital mortality in moderate-severe TBI (msTBI) patients. ⋯ When concomitantly adjusting for the burden of hyperchloremia and hypernatremia, only hyperchloremia was independently associated with in-hospital mortality in our msTBI cohort. Pending validation, our findings may provide the rationale for future studies with targeted interventions to reduce hyperchloremia and improve outcomes in msTBI patients.

Randomized Controlled Trial
Relationship of White Matter Lesions with Intracerebral Hemorrhage Expansion and Functional Outcome: MISTIE II and CLEAR III.
Intracerebral hemorrhage (ICH) patients commonly have concomitant white matter lesions (WML) which may be associated with poor outcome. We studied if WML affects hematoma expansion (HE) and post-stroke functional outcome in a post hoc analysis of patients from randomized controlled trials. ⋯ http://www.clinicaltrials.gov trial-identifiers: NCT00224770 and NCT00784134.

Anxiety is common in patients experiencing neurocritical illness and their family caregivers. Resilience factors like mindfulness and coping skills may be protective against symptoms of emotional distress, including anxiety. Less is known about the interplay of anxiety symptoms and resilience factors between patients and caregivers. The purpose of this study is to examine the trajectory of anxiety symptoms among dyads of neurocritical care patients without major cognitive impairment and their family caregivers and to elucidate the relationship between resiliency (e.g., mindfulness and coping) and anxiety in these dyads. ⋯ Anxiety symptoms in Neuro-ICU patient-caregiver dyads are high through 6 months following admission. Mindfulness is interdependent and protective against anxiety in dyads at 3-month but not 6-month follow-up. Early, dyad-based interventions may prevent the development of chronic anxiety in patients without major cognitive impairment and caregivers.

Randomized Controlled Trial Observational Study
Burst Suppression: Causes and Effects on Mortality in Critical Illness.
Burst suppression in mechanically ventilated intensive care unit (ICU) patients is associated with increased mortality. However, the relative contributions of propofol use and critical illness itself to burst suppression; of burst suppression, propofol, and critical illness to mortality; and whether preventing burst suppression might reduce mortality, have not been quantified. ⋯ Our analysis clarifies how important factors contribute to mortality in ICU patients. Burst suppression appears to contribute to mortality but is primarily an effect of critical illness rather than iatrogenic use of propofol.
