Multicenter Study
Thrombectomy Technique Predicts Outcome in Posterior Circulation Stroke-Insights from the STAR Collaboration.
Randomized controlled trials evaluating mechanical thrombectomy (MT) for acute ischemic stroke predominantly studied anterior circulation patients. Both procedural and clinical predictors of outcome in posterior circulation patients have not been evaluated in large cohort studies. ⋯ Despite similar safety profiles, use of ADAPT is associated with higher rates of functional independence after posterior circulation thrombectomy compared to stent retriever or combined approach in large "real-world" retrospective study.

Diffusion magnetic resonance (MR) characteristics are a predictive imaging biomarker for survival benefit in recurrent glioblastoma treated with anti-vascular endothelial growth factor (VEGF) therapy; however, its use in large volume recurrence has not been evaluated. ⋯ Pretreatment diffusion MR imaging is an independent predictive biomarker for overall survival in recurrent glioblastoma with a large tumor burden. Large tumors with low ADCL have a survival benefit when treated with surgical resection, whereas large tumors with high ADCL may be best managed with bevacizumab.

Comparative Study
Drug-Coated Balloon Dilation Compared With Conventional Stenting Angioplasty for Intracranial Atherosclerotic Disease.
Conventional stent-based angioplasty was challenged for the high incidence of perioperative complications and follow-up in-stent restenosis (ISR) in treating intracranial atherosclerotic disease (ICAD). Currently, the drug-coated balloon (DCB) has shown promise in preventing and treating ISR. ⋯ Compared with conventionally only stenting angioplasty, DCB dilation can effectively lower restenosis degree and total restenosis risk, with no superiority in symptomatic restenosis at 6-mo follow-up.

The Sport Concussion Assessment Tool (SCAT) could be improved by identifying critical subsets that maximize diagnostic accuracy and eliminate low information elements. ⋯ We identified SCAT subsets that accurately assess acute concussion and improve administration time over the complete battery, highlighting the importance of eliminating "noisy" elements. These findings can direct clinicians to the SCAT components that are most sensitive to acute concussion.

For laminectomy and posterior spinal fusion (LPSF) surgery for cervical spondylotic myelopathy (CSM), the evidence is unclear as to whether fusions should cross the cervicothoracic junction (CTJ). ⋯ Subaxial LPSF for CSM that crossed the CTJ were associated with superior radiographic outcomes for cSVA, CL, and CL minus T1-slope, but longer operative times. There were no differences in neck pain or reoperation rate.
