Meta AnalysisTherapeutic effect of erythropoietin in patients with traumatic brain injury: a meta-analysis of randomized controlled trials.
OBJECTIVE Erythropoietin (EPO) exerts a neuroprotective effect in animal models of traumatic brain injury (TBI). However, its effectiveness in human patients with TBI is unclear. In this study, the authors conducted the first meta-analysis to assess the effectiveness and safety of EPO in patients with TBI. ⋯ CONCLUSIONS The authors suggested that EPO is beneficial for patients with TBI in terms of reducing mortality and shortening hospitalization time without increasing the risk of DVT. However, its effect on improving favorable neurological outcomes did not reach statistical significance. Therefore, more well-designed RCTs are necessary to ascertain the optimum dosage and time window of EPO treatment for patients with TBI.

Multicenter StudyPipeline for uncoilable or failed aneurysms: 3-year follow-up results.
OBJECTIVE The long-term effectiveness of endovascular treatment of large and giant wide-neck aneurysms using traditional endovascular techniques has been disappointing, with high recanalization and re-treatment rates. Flow diversion with the Pipeline Embolization Device (PED) has been recently used as a stand-alone therapy for complex aneurysms, showing significant improvement in effectiveness while demonstrating a similar safety profile to stent-supported coil treatment. However, relatively little is known about its long-term safety and effectiveness. ⋯ CONCLUSIONS Pipeline embolization is safe and effective in the treatment of complex large and giant aneurysms of the intracranial internal carotid artery. Unlike more traditional endovascular treatments, flow diversion results in progressive vascular remodeling that leads to complete aneurysm obliteration over longer-term follow-up without delayed aneurysm recanalization and/or growth. Clinical trial registration no.: NCT00777088 (clinicaltrials.gov).

Multicenter StudyPulseRider-assisted treatment of wide-necked intracranial bifurcation aneurysms: safety and feasibility study.
OBJECTIVE The goal of this study was to assess the safety and feasibility of PulseRider, a novel endovascular stent, in the treatment of intracranial bifurcation aneurysms with wide necks. The authors present the initial results of the first 10 cases in which the PulseRider device was used. METHODS Patients whose aneurysms were intended to be treated with the PulseRider device at 2 institutions in the United Kingdom were identified prospectively. ⋯ It works by providing a scaffold at the neck of the bifurcation aneurysm, enabling neck remodeling and coil support while maintaining parent vessel intraluminal patency. Early clinical and radiological follow-up showed good functional outcome and stable occlusion rates, respectively. Further data are needed to assess medium- and long-term outcomes with PulseRider.

A prospective analysis of hypovitaminosis D and mortality in 400 patients in the neurocritical care setting.
OBJECTIVE Hypovitaminosis D is highly prevalent among the general population. Studies have shown an association between hypovitaminosis D and multiple negative outcomes in critical care patients, but there has been no prospective evaluation of vitamin D in the neurological critical care population. The authors examined the impact of vitamin D deficiency on in-hospital mortality and a variety of secondary outcomes. ⋯ For patients admitted to the NCCU on an emergency basis (n = 285), higher Simplified Acute Physiology Score II (OR 13.8, 95% CI 1.7-110.8; p = 0.014), and vitamin D deficiency (OR 3.0, 95% CI 1.0-8.6; p = 0.042) were significantly associated with increased in-hospital mortality after adjusting for other factors. CONCLUSIONS In the subset of patients admitted to the NCCU on an emergency basis, vitamin D deficiency is significantly associated with higher in-hospital mortality. Larger studies are needed to confirm these findings and to investigate the role of vitamin D supplementation in these patients.

The effects of new or worsened postoperative neurological deficits on survival of patients with glioblastoma.
OBJECTIVE An increased extent of resection (EOR) has been shown to improve overall survival of patients with glioblastoma (GBM) but has the potential for causing a new postoperative neurological deficit. To investigate the impact of surgical neurological morbidity on survival, the authors performed a retrospective analysis of the clinical data from patients with GBM to quantify the impact of a new neurological deficit on the survival benefit achieved with an increased EOR. METHODS The data from all GBM patients who underwent resection at the University of Florida from 2010 to 2015 with postoperative imaging within 72 hours of surgery were included in the study. ⋯ Any survival benefit from achieving a 95% EOR was abrogated by the development of a new neurological deficit postoperatively. CONCLUSIONS Developing a new neurological deficit after resection of GBM is associated with a decrease in overall survival. A careful balance between EOR and neurological compromise needs to be taken into account to reduce the likelihood of neurological morbidity from surgery.
