Review Meta Analysis
A meta-analysis of the predictive significance of the island sign for hematoma expansion in intracerebral hemorrhage.
The island sign of non-contrast computed tomography is a risk factor for hematoma expansion (HE) after spontaneous intracerebral hemorrhage, but has inconsistent conclusions. A meta-analysis was performed to investigate the predictive accuracy of island sign for HE. ⋯ This meta-analysis suggests that island sign of non-contrast computed tomography has a good predictive accuracy for hematoma enlargement in intracerebral hemorrhage.

Review Meta Analysis
Prognostic role of BRAF mutation in low grade gliomas: a meta-analysis.
Newly emerged molecular markers in gliomas provide prognostic values beyond the capabilities of histologic classification. BRAF mutation, especially BRAF V600E, is common in a subset of gliomas and may represent a potential prognostic marker. The aim of our study is to investigate the potential use of BRAF mutations on the prognosis of low-grade glioma patients. ⋯ This mutation can be used as a prognostic factor in low-grade glioma, but additional studies are required to clarify its prognostic value taking into account other confounding factors.

Review Meta Analysis
Facet tropism in lumbar spine and cervical spine: A systematic review and meta-analysis.
Facet tropism (FT) refers to the difference in the orientation of facet joints with respect to each other in the sagittal plane. FT leads to unequal biomechanical forces on facet joint and intervertebral disc during rotation and other physiologic movements. Most of the studies have reported the incidence of FT in the lumbar spine to vary between 40% and 70%, with L4-5 level being the most commonly afflicted level. The objective of this study was to find the association between FT and various lumbar and cervical degenerative disorders. ⋯ FT is significantly associated with LDH and LDS along with various other lumbar and cervical degenerative diseases.

The Effects of BIS-guided Anesthesia on Postoperative Delirium in Elderly Patients: -A Systematic Review and Meta-Analysis.
Postoperative delirium (POD) is a form of delirium that affects patients who have undergone surgical procedures and anesthesia, usually peaking between 1 and 3 days after their operation. The aim of this meta-analysis was to determine whether monitoring of depth of anesthesia may influence the incidence of POD. ⋯ BIS monitoring during surgery can reduce the incidence of POD in elderly patients. Whether BIS monitoring may reduce the incidence of POD in a single type of surgery needs further study.
