Review Meta Analysis Comparative Study
Comparative assessment of three posterior fossa decompression techniques and evaluation of the evidence supporting the efficacy of syrinx shunting and filum terminale sectioning in Chiari malformation type I. A systematic review and network meta-analysis.
This study aimed to compare the effectiveness of posterior fossa decompression (PFD), posterior fossa decompression with duraplasty (PFDD), and posterior fossa decompression with resection of tonsils (PFDRT) in Chiari malformation type I (CMI). Furthermore, we aimed to evaluate the evidence supporting the efficacy of filum terminale sectioning (FTS), syringosubarachnoid shunting (SSS), and syringoperitoneal shunting (SPS) in CMI. ⋯ PFDD and PFDRT are superior to PFD, especially in patients with syringomyelia-Chiari complex, because of greater syringomyelia reduction and better clinical improvement. However, PFDD and PFDRT can be considered equally efficient. There is no evidence pleading in favor of SFT, SSS, and SPS over any PFD technique.

Meta Analysis
Outcomes of Pre-injury Utilization of Statins in Patients with Traumatic Brain Injury: A Systematic review and Meta-analysis.
No completely effective pharmacotherapies have been developed to improve the outcomes of traumatic brain injury (TBI). Given the reporting of cohort studies suggesting that preinjury statin use may reduce TBI-associated mortality, this study aimed to evaluate the effects of statin use in patients with TBI. ⋯ Preinjury statin use may contribute to mortality reduction in patients with TBI, whereas statin withdrawal might increase mortality. In clinical management, statin use should not be discontinued after TBI.

Meta Analysis
Effectiveness of pre-operative embolization in patients with spinal metastases: a systematic review and meta-analysis.
Debate on the effectiveness of preoperative embolization for spinal metastatic lesions, especially for nonhypervascular tumors, has persisted. The present study aimed to identify the effectiveness of preoperative embolization in patients who had undergone surgery for spinal metastasis. ⋯ The current data support the use of preoperative embolization for hypervascular metastatic tumors to the spine. However, little evidence is available to support the use of preoperative embolization for nonhypervascular metastatic tumors to the spine.
