The relationship between uptake of amino acid tracer with positron emission tomography (PET) and glioma subtypes/gene status is still unclear. ⋯ Distinguishing glioma subtypes based on the revised 2016 World Health Organization classification of the central nervous system tumors on the basis of [11C]methionine PET alone seems to be difficult. However, [11C]methionine PET might be useful for predicting the IDH mutation status in newly diagnosed and untreated gliomas noninvasively before tumor resection.

The cause of surfer myelopathy remains enigmatic and long-term follow-up outcomes are not well documented. In the present study, the mechanisms underlying surfer myelopathy in children are analyzed and the long-term follow-up outcomes are reported. ⋯ Surfer myelopathy in children is caused by spinal venous hypertension. The AIS grade on admission is a predictor of prognosis.

Various prognostic models are used to predict mortality and functional outcome in patients after traumatic brain injury with a trend to incorporate machine learning protocols. None of these models is focused exactly on the subgroup of patients indicated for decompressive craniectomy. Evidence regarding efficiency of this surgery is still incomplete, especially in patients undergoing primary decompressive craniectomy with evacuation of traumatic mass lesions. ⋯ Random forest algorithms show promising results in prediction of postoperative outcome and mortality in patients undergoing primary decompressive craniectomy. The best performance was achieved by Classification Random forest for 6-month outcome.

Asymptomatic or minor symptom meningiomas (AMSMs) in the elderly are incidental findings, with no consensus reached on the optimal management strategy. In the present study, we aimed to determine the surgical risk factors for elderly patients with AMSMs using a nationwide registry database in Japan. ⋯ For elderly patients with surgically treated AMSMs, advanced age was a prominent risk factor for functional decline at discharge. Our study identified several factors that should be evaluated before proceeding with surgery for AMSMs in elderly and pre-elderly patients. These findings could, not only improve decision-making among clinicians treating patients with AMSMs, but also help in predicting the results of surgery for elderly patients with AMSMs.

Comparative Study
Sex Differences in Postoperative Complications and Functional Status After Deformity Correction Surgery: Do Men Fare Better Than Women?
We investigated whether a sex-related difference exists in the postoperative complication risk and health-related quality of life measures after surgery for adult spinal deformity. ⋯ In the present study, after adjustment for important baseline prognostic factors, no differences were found in the postoperative complication rates or extent of functional improvement when stratified by sex. Both sexes responded equally well to corrective surgery for symptomatic adult spinal deformity.
