Review Meta Analysis
Evidence for Mannitol as an Effective Agent Against Intracranial Hypertension: An Individual Patient Data Meta-analysis.
Mannitol is currently used to reduce intracranial pressure (ICP), but the evidence supporting its usefulness has been questioned. We aim to meta-analyze the effectiveness of mannitol in reducing ICP in adult patients with cerebral injuries and its dependency on baseline ICP values, comparing findings from individual patient data (IPD) and aggregated data (AD) meta-analysis performed on the same studies. We searched the Medline database, with no time limitation, through March 1, 2019. ⋯ The AD meta-analysis, based on data collected between 30 and 60 min from mannitol administration not accounting for multiple time-point measurements, overestimated ICP reduction (10 mmHg), while meta-regression provided similar results (0.66 mmHg decrease for each unitary increase of initial ICP). Mannitol is effective in reducing pathological ICP, proportionally to the degree of intracranial hypertension. IPD meta-analysis provided a more precise quantification of ICP variation than the AD approach.

Randomized Controlled Trial
White Matter Hyperintensities and Blood Pressure Lowering in Acute Intracerebral Hemorrhage: A Secondary Analysis of the ATACH-2 Trial.
It is not clear whether subsets of patients with intracerebral hemorrhage (ICH) benefit from intensive blood pressure (BP) lowering. We evaluated whether white matter hyperintensities (WMH) burden influences response to this therapy. ⋯ The majority of acute ICH patients have moderate-severe WMH, but advanced small vessel disease burden marked by WMH does not influence ICH-related outcomes or response to intensive BP reduction.

Observational Study
Global Survey of Outcomes of Neurocritical Care Patients: Analysis of the PRINCE Study Part 2.
Neurocritical care is devoted to the care of critically ill patients with acute neurological or neurosurgical emergencies. There is limited information regarding epidemiological data, disease characteristics, variability of clinical care, and in-hospital mortality of neurocritically ill patients worldwide. We addressed these issues in the Point PRevalence In Neurocritical CarE (PRINCE) study, a prospective, cross-sectional, observational study. ⋯ PRINCE is the first study to evaluate care patterns of neurocritical patients worldwide. The data suggest that there is a wide variability in clinical care resources and patient characteristics. Neurological severity of illness and the absence of a dedicated NCCU are independent predictors of in-patient mortality.
