Review Meta Analysis
Ultra-early angiographic vasospasm following aneurysmal subarachnoid hemorrhage: a systematic review and meta-analysis.
After aneurysmal subarachnoid hemorrhage (aSAH), prognosis is affected heavily by the presence of delayed cerebral ischemia (DCI). There is growing recognition of ultra-early angiographic vasospasm (UEAV) occurring within 48 hours of aSAH; however, its relationship with DCI and ultimately prognosis remains unclear. ⋯ UEAV was significantly associated with symptomatic cerebral vasospasm, DCI/infarction, unfavorable outcome at follow-up, and greater mortality. Patients with intracerebral hematoma, intraventricular hemorrhage (Fisher Grade IV), larger ruptured aneurysms >12 mm, and an MCA location were more likely to have UEAV.

Review Meta Analysis
Comparative outcomes of cortical screw trajectory fixation and pedicle screw fixation in lumbar spinal fusion: A systematic review and meta-analysis.
We conducted a systematic review and meta-analysis to compare the postoperative outcomes of cortical screw and pedicle screw (PS) fixation techniques for posterior lumbar interbody fusion (PLIF). ⋯ PLIF with CBT screw fixation had postoperative back and leg pain, disabilities, and function score.
