Observational Study
Men Experience Higher Risk of Pneumonia and Death After Intracerebral Hemorrhage.
Infectious complications worsen outcome after intracerebral hemorrhage (ICH). We investigated the impact of sex on post-ICH infections and mortality. ⋯ Types and rates of infection following ICH differ by sex. Male sex independently increases pneumonia risk, which subsequently increases 90-day mortality. Sex-specific preventive strategies to reduce the risk of these complications may be one strategy to improve ICH outcomes.

Controlled Clinical Trial
Albumin-Induced Neuroprotection in Focal Cerebral Ischemia in the ALIAS Trial: Does Severity, Mechanism, and Time of Infusion Matter?
To determine whether there is any differential benefit of albumin administration within 2 h of onset of ischemia and in settings (severe ischemia with reperfusion in cardioembolic strokes with National Institutes of Health Stroke Scale [NIHSS] ≥15), most representative of experimental models of cerebral ischemia in which albumin was effective in reducing neurological injury. ⋯ A trend for benefit is noted in ischemic stroke patients with large cardioembolic stroke (NIHSS ≥15) when high-dose albumin was initiated within 2 h, suggesting that certain ischemic stroke subgroups of patients most representative of preclinical settings may benefit from such a treatment. Additional clinical trials maybe needed to stratify subjects and treatment assignments according to NIHSS severity and timely randomization to evaluate this concept further.

Long-term continuous intra-arterial nimodipine infusion (CIAN) is a rescue therapy option in cases of severe refractory cerebral vasospasm (CV) following acute non-traumatic subarachnoid hemorrhage (SAH). However, CIAN therapy can be associated with relevant side effects. Available studies focus on intracerebral complications, whereas extracerebral side effects are rarely examined. Aim of the present study was to generate descriptive data on the clinical course during CIAN therapy and expectable extracerebral side effects. ⋯ Long-term CIAN therapy is associated with diverse side effects. The leading problems are an impairment of the hemodynamic situation and cardiac problems, an increase in infectious complications, a worsening of the motility of the gastrointestinal tract, and rising ICP values. Teams on neurointensive care units must be aware of these side effects to avoid that the beneficial effects of CIAN therapy on CV reported elsewhere are foiled by the problems this technique can be associated with.

Systemic inflammatory response syndrome (SIRS) is frequently observed after various types of acute cerebral injury and has been linked to clinical deterioration in non-traumatic brain injury (TBI). SIRS scores have also been shown to be predictive of length of stay and mortality in trauma patients. We aimed to determine the prognostic utility of SIRS present at admission in trauma patients with isolated TBI. ⋯ Prognostic, Level III.

Cerebral edema, which is associated with increased intracranial fluid, is often a complication of many acute neurological conditions. There is currently no accepted method for real-time monitoring of intracranial fluid volume at the bedside. We evaluated a novel noninvasive technique called "Volumetric Integral Phase-shift Spectroscopy (VIPS)" for detecting intracranial fluid shifts during hemodialysis. ⋯ We detected an increase in the VIPS edema index during hemodialysis that correlated with decreased serum osmolarity, mainly reflected by changes in serum sodium suggesting shifts in intracranial fluids.
