Summary: This study highlights the importance of genomic analysis in neurooncology in understanding different molecular subtypes of gliomas and their responses to treatment. The study found that greater extent of resection (EOR) was associated with increased overall survival in both historically classified oligodendrogliomas and 1p/19q-codeleted tumors. Various factors such as tumor grade, location, and size, as well as age, comorbidity index, and treatment methods were shown to be significant predictors of overall survival.

Summary: The study evaluates the survival benefits of additional resection, including lobectomy, in patients with glioblastoma undergoing supratotal resection (SupTR). The results show that SupTR with lobectomy leads to superior progression-free survival (PFS) and overall survival (OS) without negatively affecting patient performance. The O6-DNA-methylguanine methyltransferase (MGMT) promoter methylation status is identified as a predictor for both superior PFS and OS.

Summary: Glioblastoma is the most common aggressive adult brain tumor. The publicly available datasets for glioblastoma studies have limitations in terms of subject number, acquisition protocol consistency, data quality, and clinical information. To address these limitations, the University of Pennsylvania has contributed the UPenn-GBM dataset, which is currently the largest publicly available collection of 630 patients diagnosed with de novo glioblastoma. This dataset includes advanced multi-parametric magnetic resonance imaging scans, clinical and molecular information, derivative volumes, expert annotations, and quantitative imaging features.

Summary: This study aimed to investigate the association between a greater extent of resection of the temporal portion of the piriform cortex and seizure freedom in children undergoing anterior temporal lobe resection for temporal lobe epilepsy. The results showed that in children with ipsilateral hippocampal atrophy, a greater extent of temporal piriform cortex resection was associated with a higher chance of seizure freedom. However, in the overall study group, the extent of piriform cortex resection was not associated with seizure outcome.

Summary: This study found a differential cerebrospinal fluid (CSF) dynamics pattern between patients with Long-standing Overt Ventriculomegaly in Adults (LOVA) and those with idiopathic normal pressure hydrocephalus (iNPH). A higher proportion of LOVA patients showed isolated compliance impairment. Therefore, CSF dynamics analysis plays a significant role in evaluating LOVA patients, and future research may help define diagnosis and treatment algorithms for LOVA based on CSF dynamics analysis.

Summary: The study aimed to assess the impact of MYO1E overexpression on non-small cell lung carcinoma (NSCLC) and investigate the association between DNA methylation, RNA expression of MYO1E, and survival/mortality risk in NSCLC patients. The results show a negative correlation between DNA methylation and RNA expression of MYO1E in both LUAD and LUSC subpopulations. Late-stage LUAD patients had lower DNA methylation and higher RNA expression of MYO1E, while no significant differences were observed in LUSC patients. Low DNA methylation and high RNA expression of MYO1E were associated with shorter median survival time and increased mortality risk in LUAD, but not in LUSC. This study suggests that changes in MYO1E methylation and expression play a crucial role in the pathogenesis of lung cancer, particularly in LUAD, and highlights the potential utility of MYO1E DNA methylation and RNA expression as predictors of survival for LUAD patients. Furthermore, MYO1E DNA methylation could be used as a circulating tumor marker in liquid biopsies due to its low normal expression in blood cells.

Summary: The aim of this study was to compare the clinical and functional performances of INPH patients with and without parkinsonism at different stages of evaluation and surgery. The results showed that patients with parkinsonism performed worse than those without parkinsonism. Unsatisfactory response to the CSF tap test should not exclude INPH patients with parkinsonism from VPS surgery.

Summary: This study used a rat model of traumatic SCI to identify transcriptome changes and potential therapeutic value of Tamoxifen. Transcriptome analysis revealed differential gene expression related to SCI and inflammatory response. Tamoxifen was found to regulate the expression changes of Ccr2 and Mmp12 genes. These findings contribute to our understanding of Tamoxifen as a potential therapeutic resource for traumatic SCI during the acute phase.

Summary: This study aimed to compare the effect of different Modic changes (MC) grades on the cage subsidence rate after spinal interbody fusion surgery. A meta-analysis was conducted on relevant randomized controlled trials and cohort studies. The results showed that MC may be associated with a higher cage subsidence rate. With the increase in MC grades, the incidence of subsidence decreased gradually, but it was always higher than that in the non-Modic changes (NMC). Oblique lumbar interbody fusion may be a better treatment choice for lumbar degenerative disease with MC.
