The outcomes of patients with non-shockable out-of-hospital cardiac arrest (non-shockable OHCA) are poorer than those of patients with shockable out-of-hospital cardiac arrest (shockable OHCA). In this retrospective study, we selected patients from the SOS-KANTO 2012 study with non-shockable OHCA that developed after emergency medical service (EMS) arrival and analyzed the effect of therapeutic hypothermia (TH) on non-shockable OHCA patients. ⋯ In this study, TH was an independent prognostic factor for the 3-month cerebral function outcome. Even in patients with non-shockable OHCA, TH may improve outcome if the interval from the onset of cardiopulmonary arrest is relatively short, and adequate cardiopulmonary resuscitation is initiated immediately after onset.

Randomized Controlled Trial
Early Manipulation of Arterial Blood Pressure in Acute Ischemic Stroke (MAPAS): Results of a Randomized Controlled Trial.
There is uncertainty over the optimal level of systolic blood pressure (SBP) in the setting of acute ischemic stroke (AIS). The aim of this study was to determine the efficacy of the early manipulation of SBP in non-thrombolised patients. The key hypothesis under investigation was that clinical outcomes vary across ranges of SBP in AIS. ⋯ Good outcome in 90 days was not significantly different among the 3 blood pressure ranges. After logistic regression analysis, the odds of having good outcome was greater in Group 2 (SBP 161-180 mmHg). SICH occurred more frequently in Group 3 (181-200 mmHg).

Intracranial pressure (ICP) monitoring is fundamental for neurocritical care patient management. For many years, ventricular and parenchymal devices have been available for this aim. The purpose of this paper is to review the published literature comparing ICP recordings via an intraventricular catheter or an intraparenchymal (brain tissue) catheter. ⋯ We propose two new terms that more accurately identify the anatomical site of recording for the referenced ICP: intracranial pressure ventricular (ICP-v) and intracranial pressure brain tissue (ICP-bt). Further delineation of the conventional term "ICP" into these two new terms will clarify the difference between ICP-v and ICP-bt and their respective measurement locations.

Studies suggested that the neutrophil-to-lymphocyte ratio (NLR) was associated with unfavorable outcomes in different diseases such as intracerebral hemorrhage, cardiovascular problem, cancer, and severe traumatic brain injury (sTBI). We aimed to evaluate the relationship between peak NLR and 1-year outcomes in patients with sTBI. ⋯ Peak NLR was associated with the clinical prognosis after sTBI and was a promising predictor for 1-year outcomes.

Observational Study
Admission Heart Rate Variability is Associated with Fever Development in Patients with Intracerebral Hemorrhage.
Fever is associated with worse outcome after intracerebral hemorrhage (ICH). Autonomic dysfunction, commonly seen after brain injury, results in reduced heart rate variability (HRV). We sought to investigate whether HRV was associated with the development of fever in patients with ICH. ⋯ HRV measured on 10-second EKGs is a potential early marker of parasympathetic nervous system dysfunction and is associated with subsequent fever occurrence after ICH. Detecting early parasympathetic dysfunction may afford opportunities to improve ICH outcome by targeting therapies at fever prevention.
