Elevated preoperative neutrophil-to-lymphocyte ratio as a predictor of worse survival after resection in patients with brain metastasis.
OBJECTIVE The median postoperative survival duration of patients with brain metastases who undergo tumor resection is 12 months. Most of these patients die of systemic metastases or the progression of primary cancer but not brain metastases. The criteria for indicating resection are still controversial. ⋯ A significant difference in the median OS was found: 14 months for 82 patients with an NLR < 5 versus 5 months for 23 patients with an NLR ≥ 5 (p = 0.001). CONCLUSIONS In this study, an elevated preoperative NLR is a predictor of worse survival after resection for brain metastases. NLR is a simple, systemic marker and can be used in clinical settings for decision making regarding resection in patients with brain metastases.

Evaluating the complexity of online patient education materials about brain aneurysms published by major academic institutions.
OBJECTIVE Health care education resources are increasingly available on the Internet. A majority of people reference these resources at one point or another. A threshold literacy level is needed to comprehend the information presented within these materials. ⋯ An ANOVA test found that there were no significant differences in readability among the materials from the institutions (p = 0.215). CONCLUSIONS Brain aneurysms affect 3.2% of adults 50 years or older across the world and can cause significant patient anxiety and uncertainty. Current patient education materials are not written at or below the NIH's recommended 4th- to 6th-grade education level.

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.
