Little is known about the independent association of language barriers on postoperative process outcomes after craniotomies. ⋯ LEP is an independent risk factor for extended LOS, higher hospitalization cost, and discharge to skilled care in neurosurgical patients who undergo craniotomy for brain tumor. Future research should seek to understand mediators of these observed disparities.

Previous studies comparing hearing outcomes in patients managed with stereotactic radiosurgery (SRS) and a watch-and-wait strategy were limited by small sample sizes that prevented controlling for potential confounders, including initial hearing status, tumor size, and age. ⋯ When controlling for potential confounders, there was no significant difference in loss of class A or serviceable hearing between patients managed with SRS or with observation alone.

Glioblastoma (GBM) is the most common malignant primary brain tumor with a universally poor prognosis. GBMs express elevated levels of hexokinase 2 (HK2), catalyzing the critical step in glycolysis and influencing several oncogenic pathways. Previous preclinical work has suggested a role for repurposed posaconazole (PCZ) in downregulating HK2 activity, reducing lactate and pyruvate production, interfering with tumor cell metabolism, and increasing mouse survival. ⋯ A successful trial will support the decision to proceed to advanced phase trials. Any tumor penetration by PCZ, with concomitant effect on glycolysis, warrants further in-depth analysis, as therapeutic options for these deadly tumors are currently limited.

Stereoelectroencephalography (sEEG) facilitates electrical sampling and evaluation of complex deep-seated, dispersed, and multifocal locations. Granger causality (GC), previously used to study seizure networks using interictal data from subdural grids, may help identify the seizure-onset zone from interictal sEEG recordings. ⋯ Granger analysis can identify seizure foci from interictal sEEG and correlates highly ranked nodes with favorable outcome, potentially informing surgical decision-making without reliance on ictal recordings.

Despite formal cardiac clearance, a subset of 3-column osteotomy (3CO) patients still experience cardiac complications (CCs). ⋯ RCRI and MET functional ability are limited risk assessment tools in ASD 3CO patients with formal cardiac clearance. Patients older than 81 years are at high risk for CC. In younger patients, cardiac EF and blood loss are significant components to risk stratify for CC.
