Article Abstract
Objective: Physical and mental status of neurosurgeons may vary with emergency status and hours of operation, which may impact the outcome of patients undergoing surgery. This study aims to clarify the influence of these parameters on outcome after surgery in glioma patients.
Patients And Methods: A total of 477 nonemergency surgery (NES) and 30 emergency surgery (ES) were enrolled in this study. Using propensity score matching (PSM) analysis, 97 pairs of procedures from NES group were generated and then classified as group M (morning procedures, 8:00 a.m-1:00 p.m) or group A (afternoon or night procedures, 1:00 p.m-8:00 p.m). 30 emergency procedures were classified into group ESa (daytime emergency surgery, 8:00 a.m-6:00 p.m) and group ESb (nighttime surgery procedures, 6:00 p.m-8:00 a.m the next day). Differences in intraoperative risk factors and postoperative complications were analyzed.
Results: Postoperative complications, including death within 30 days (p = 0.004), neurological function deficit (p = 0.012), systemic infection (p < 0.001) were significant higher in emergency procedures. Intraoperative risk factors including blood loss (p < 0.001), blood transfusion (p = 0.036) were also higher in emergency procedures than nonemergency procedures, although both procedures had comparable time duration (p = 0.337). By PSM analysis, patients in group M and group A were well matched and no significant difference of intraoperative risk factors and postoperative complications (all p > 0.05) were found. Furthermore, incidence of intraoperative risk factors and postoperative complications were similar in both groups ESa and ESb (all p > 0.05).
Conclusion: Emergency glioma resection is a very important risk factors of perioperative mortality and morbidity for patients. However, hours of operation did not necessarily predict postoperative mortality or morbidity, either in emergency or nonemergency glioma resection.

Predictive role of MGMT and IDH status in the efficacy of bevacizumab for high-grade glioma: a retrospective study.
Front Oncol

Department of Neurosurgery, Tengzhou Central People's Hospital, Tengzhou, Shandong, China.
Background: The objective of this study is to investigate the predictive role of O6-methylguanine-DNA methyltransferase (MGMT) and isocitrate dehydrogenase (IDH) status on the efficacy of bevacizumab (BEV) in high-grade glioma (HGG), while excluding the interference of chemotherapy agents.
Methods: A retrospective, single-center analysis was conducted on 103 patients with HGG who received BEV treatment. The enrolled patients were grouped based on their different biomarker statuses.
Prognostic value of [F]FET-PET in diffuse low-grade (grade 2) gliomas after the 2021 classification of CNS tumors.

Purpose: Amino acid PET with [F]-fluoroethylthyrosine ([F]FET-PET) is frequently utilized in gliomas. Most studies on prognostication based on amino acid PET comprise mixed cohorts of brain tumors with low- and high-grade features. The objective of this study was to assess the potential prognostic value of [F]FET-PET-based markers in the group of grade 2 adult-type diffuse gliomas, as defined by the WHO CNS 2021 classification.

The multifunctional systems presented here introduce an innovative and deeply thought-out approach to the more effective and safer use of temozolomide (TMZ) in treating glioma. The developed hydrogel-based flakes were designed to address the issues of local GBL therapy, bacterial neuroinfections, and the bleeding control needed during tumor resection. The materials obtained comprise TMZ and vancomycin (VANC) loaded into cyclodextrin/polymeric capsules and embedded into gelatin/hyaluronic acid/chitosan-based hydrogel films cross-linked with genipin.

Purpose: Resection of glioblastomas infiltrating the motor cortex and corticospinal tract (CST) is often linked to increased perioperative morbidity. Navigated transcranial magnetic stimulation (nTMS) motor mapping has been advocated to increase patient safety in these cases. The additional impact of patient frailty on overall outcome after resection of cases with increased risk for postoperative motor deficits as identified with nTMS needs to be investigated.

Background: High-grade astrocytoma with piloid features (HGAP) was recently added to the WHO 2021 CNS classification system among the group of circumscribed astrocytic gliomas. These tumors present with high-grade piloid histology with similarities to glioblastoma. HGAPs in the pineal region become particularly challenging due to its deep location and proximity to deep venous structures, the midbrain, and the thalamus.
