Meta AnalysisPrevalence and characteristics of brain arteriovenous malformations in hereditary hemorrhagic telangiectasia: a systematic review and meta-analysis.
OBJECTIVE Patients with hereditary hemorrhagic telangiectasia (HHT) are known to suffer from high rates of cerebral arteriovenous malformations (AVMs). The authors performed a systematic review and meta-analysis of the literature examining prevalence rates, characteristics, and clinical presentation of cerebral AVMs in the HHT population. METHODS To identify studies on AVM prevalence and characteristics in the HHT population, 4 databases (MEDLINE, EMBASE, Scopus and Web of Science) were searched by a reference librarian with over 30 years experience in systematic reviews and meta-analysis. ⋯ HHT1 patients are significantly more likely to have brain AVMs than HHT2 patients. Most AVMs in the HHT population are symptomatic. The Spetzler-Martin grade for these lesions is 2 or less in nearly 90% of patients.

Meta AnalysisEffect of statin treatment on vasospasm-related morbidity and functional outcome in patients with aneurysmal subarachnoid hemorrhage: a systematic review and meta-analysis.
OBJECTIVE The efficacy of statin therapy in treating aneurysmal subarachnoid hemorrhage (SAH) remains controversial. In this meta-analysis, the authors investigated whether statin treatment significantly reduced the incidence of cerebral vasospasm and delayed neurological deficits, promoting a better outcome after aneurysmal SAH. METHODS A literature search of the PubMed, Ovid, and Cochrane Library databases was performed for randomized controlled trials (RCTs) and prospective cohort studies investigating the effect of statin treatment. ⋯ CONCLUSIONS Treatment with statins significantly decreased the occurrence of vasospasm after aneurysmal SAH. The incidence of DIND, delayed cerebral infarction, and mortality were not affected by statin treatment. Future research should focus on DIND and how statins influence DIND.

A systematic review of 30-day readmission after cranial neurosurgery.
OBJECTIVE The 30-day readmission rate has emerged as an important marker of the quality of in-hospital care in several fields of medicine. This review aims to summarize available research reporting readmission rates after cranial procedures and to establish an association with demographic, clinical, and system-related factors and clinical outcomes. METHODS The authors conducted a systematic review of several databases; a manual search of the Journal of Neurosurgery, Neurosurgery, Acta Neurochirurgica, Canadian Journal of Neurological Sciences; and the cited references of the selected articles. ⋯ Complications arising during or after neurosurgical procedures were a prime reason for readmission. Race, comorbidities, and longer hospital stay put patients at risk for readmission. CONCLUSIONS Although readmission may be an important indicator for good care for the subset of acutely declining patients, neurosurgery should aim to reduce 30-day readmission rates with improved quality of care through systemic changes in the care of neurosurgical patients that promote preventive measures.
