Meta Analysis
Imaging for Neuroprognostication After Cardiac Arrest: Systematic Review and Meta-analysis.
Predicting neurological outcome in comatose survivors of cardiac arrest relies on clinical findings, radiological and neurophysiological test results. To evaluate the predictive accuracy of brain computed tomography (CT) and magnetic resonance imaging (MRI) for prognostication of neurological outcomes after cardiac arrest. ⋯ Decreased grey to white matter ratio on CT and DWI or DWI and FLAIR on MRI are useful adjuncts for predicting poor early neurological outcome after cardiac arrest.

Randomized Controlled Trial
Sequential Pneumatic Compression in the Arm in Neurocritical Patients with a Peripherally Inserted Central Venous Catheter: A Randomized Trial.
Peripherally inserted central venous catheters (PICCs) are increasingly used for parenteral access in critically ill hospitalized patients, but they increase the incidence of upper extremity deep venous thrombosis (UE DVT). Sequential compression devices (SCDs) applied to the legs effectively reduce lower extremity DVT, but have not been tested in the arms. Our objective was to determine whether SCDs applied to the arm may reduce the risk of PICC-associated UE DVT. ⋯ Although UE DVT is commonly associated with PICC use, the results of this trial do not support the use of SCD on the arm for DVT prevention. Further research on this strategy may nonetheless be justified.

Neurocritical care focuses on the care of critically ill patients with an acute neurologic disorder and has grown significantly in the past few years. However, there is a lack of data that describe the scope of practice of neurointensivists and epidemiological data on the types of patients and treatments used in neurocritical care units worldwide. To address these issues, we designed a multicenter, international, point-prevalence, cross-sectional, prospective, observational, non-interventional study in the setting of neurocritical care (PRINCE Study). ⋯ The PRINCE Study results suggest that there is significant variability in the delivery of neurocritical care. The study also shows it is feasible to undertake international collaborations to gather global data about the practice of neurocritical care.

Accurate prediction of malignant brain edema (MBE) after stroke is paramount to facilitate close monitoring and timely surgical intervention. The Enhanced Detection of Edema in Malignant Anterior Circulation Stroke (EDEMA) score was useful to predict potentially lethal malignant edema in Western populations. We aimed to validate and modify it to achieve a better predictive value for MBE in Chinese patients. ⋯ The original EDEMA score showed an acceptable predictive value for MBE in Chinese patients. By adding the admission NIHSS score, the modified score allowed for a more accurate prediction and clinical usefulness. Further validation in large cohorts of different ethnicities is needed to confirm our findings.

Posterior reversible encephalopathy syndrome (PRES) is a clinical and radiologic entity, typically manifesting as reversible neurological symptoms and signs of white matter edema on magnetic resonance imaging. PRES has been widely described in adults. Studies of PRES in children are mostly limited to case series and case controls. ⋯ Immunosuppression, autoimmune disease, renal insufficiency, anemia, and hypertension are associated with PRES after controlling for mortality risk in critically ill children. There was no association between corrected serum calcium and sepsis with PRES.
