Review Meta Analysis
A Systematic Review and Meta-Analysis of Statins in Animal Models of Intracerebral Hemorrhage.
Intracerebral hemorrhage (ICH) is a severe form of stroke with limited treatment options. Statins have shown promise as a therapy for ICH in animal and human studies. We systematically reviewed and assessed the quality of preclinical studies exploring statin-use after ICH to guide clinical trial decision-making and design. ⋯ Behavioral outcomes in ICH were found to consistently improve with administration of statins in preclinical studies suggesting that statin therapy may be suitable for randomized clinical trials in humans. In addition, the STAIR criteria can be modified to effectively evaluate preclinical studies in ICH.

Review Meta Analysis
Fluorescein-guided Resection of High Grade Gliomas: A Meta-Analysis.
High-grade gliomas (HGGs) have a poor prognosis despite current standard of care of surgery, chemotherapy, and radiation therapy. Achieving gross total resection (GTR) has been found to prolong survival in these patients. Intraoperative fluorescent agents are often used to aid in the resection of HGGs. One commonly used fluorescent agent is fluorescein sodium, which is U.S. Food and Drug Administration-approved for ocular surgeries and has a better side effect profile and is less costly than 5-aminolevulinic acid (5-ALA). In this meta-analysis, we provide statistical evidence of the efficacy in using fluorescein for HGG resection. ⋯ This meta-analysis shows that fluorescein-guided surgery improves GTR rates of HGGs when compared with non-fluorescence guided surgery and has similar GTR rates when compared with reported 5-ALA-guided resection rates.

Stereoelectroencephalography (sEEG) is an increasingly popular surgical technique used clinically to study neural circuits involved in medication-refractory epilepsy, and it is concomitantly used in the scientific investigation of neural circuitry underlying behavior. ⋯ sEEG is an important method in epilepsy surgery that could be applied to other neurologic and psychiatric diseases. Information from these studies could provide additional pathophysiologic information and lead to further development and refinement of neuromodulation therapies for such conditions.

Ex vivo animal brain simulation models are being increasingly used for neurosurgical training because these models can replicate human brain conditions. The goal of the present report is to provide the neurosurgical community interested in using ex vivo animal brain simulation models with guidelines for comprehensively and rigorously conducting, documenting, and assessing this type of research. ⋯ The present findings should help contribute to more rigorous application, documentation, and assessment of ex vivo brain simulation research.

The Clinical Use of Serum Biomarkers in Traumatic Brain Injury: A Systematic Review Stratified by Injury Severity.
Serum biomarkers have gained significant popularity as an adjunctive measure in the evaluation and prognostication of traumatic brain injury (TBI). However, a concise and clinically oriented report of the major markers in function of TBI severity is lacking. This systematic review aims to report current data on the diagnostic and prognostic utility of blood-based biomarkers across the spectrum of TBI. ⋯ This review summarizes existing high-quality evidence that supports the use of severity-specific biomarkers in the diagnostic and prognostic evaluation of TBI. These data can be used as a launching platform for the validation of upcoming clinical studies.
