Meta Analysis
The accuracy of aneurysm size in predicting rebleeding after subarachnoid hemorrhage: a meta-analysis.
Aneurysmal subarachnoid hemorrhage (SAH) is a severe cerebrovascular disease. Rebleeding is an independent predictor of unfavorable outcome after aneurysmal SAH. However, the accuracy of aneurysm size for predicting rebleeding after aneurysmal SAH is still unclear. Hence, we conducted this meta-analysis to evaluate the predictive accuracy of large aneurysm for rebleeding after SAH. ⋯ The specificity of large aneurysm for predicting rebleeding after SAH is relatively high. However, its overall accuracy for predicting aneurysm rebleeding is not very satisfying. A comprehensive model should be developed to improve the accuracy of rebleeding prediction after SAH.

Association between aspirin use and risk of aneurysmal subarachnoid hemorrhage: a meta-analysis.
To assess the association between aspirin use and risk of aneurysmal subarachnoid hemorrhage (aSAH). ⋯ A short-term use of aspirin (<3 months) is associated with an elevated risk of aSAH, whereas the role of its long-term use in either decreasing or increasing the risk of aSAH still requires well-designed, large-scale randomized control trials for verification.

Meta Analysis
Seizure incidence of angiogram-negative subarachnoid hemorrhage: An updated meta-analysis.
To provide updated information on seizure events and patterns in patients with angiogram-negative subarachnoid hemorrhage based on the initial hemorrhage patterns: perimesencephalic subarachnoid hemorrhage (PMH) vs non-PMH. ⋯ PMH is associated with lower seizure risk than non-PMH. However, possible publication bias could be a concern to the interpretation. Additional meta-analyses based on individual patient data from prospective large-scale studies are necessary.

Meta AnalysisIn-hospital mortality and poor outcome after surgical clipping and endovascular coiling for aneurysmal subarachnoid hemorrhage using nationwide databases: a systematic review and meta-analysis.
There has never been evidence for aneurysmal subarachnoid hemorrhage (aSAH) by endovascular coiling compared to surgical clipping with all grade. The present study and meta-analysis aimed to clarify the in-hospital mortality and poor outcome in the nationwide databases of patients with all grade aSAH between them. The outcome of modified Rankin scale (mRS) at discharge was investigated according to the comprehensive nationwide database in Japan. ⋯ Meta-analysis of propensity score-matched analysis in the nationwide database showed no significant association for poor outcome at discharge between them (odds ratio [OR], 1.08; 95% confidence interval [CI], 0.93 to 1.26; p = 0.31). Meta-analysis of propensity score-matched analysis for in-hospital mortality was lower after surgical clipping than after endovascular coiling, however, without significant difference (OR, 0.74; 95% CI, 0.52 to 1.04; p = 0.08). Further prospective randomized controlled study with all grade aSAH should be necessary to validate the in-hospital mortality and poor outcome.

Meta Analysis
High leukocyte count and risk of poor outcome after subarachnoid haemorrhage - a metaanalysis.
Subarachnoid hemorrhage is (SAH) is a devastating neurologic emergency often associated with systemic inflammatory response. Many reports have demonstrated an association between elevated inflammatory markers and poor outcome. We performed an observational study and a meta-analysis of the impact of high leukocyte count on outcome after SAH. ⋯ Elevated white blood cells is a marker of poor outcome after SAH. Despite the fact that it is unlikely to be causative, it may be treated as a useful risk predictor.
