Temporal changes in the volume of chronic subdural hematoma (CSDH) following middle meningeal artery (MMA) embolization vary. We aimed to determine whether CSDH density on computed tomography is related to hematoma resolution following particle MMA embolization. ⋯ Rapid resolution of CSDH following MMA embolization was associated with low hematoma density at 1-week postembolization. Based on hematoma density on computed tomography at 1-week postembolization, a 1-month follow-up would be sufficient in cases of low density, but a 3-month follow-up would be required in cases of high-density hematoma. Larger studies and clinical trials are needed to confirm our findings.

Observational Study
Impaired dynamic cerebral autoregulation as a predictor for cerebral hyperperfusion after carotid endarterectomy: A prospective observational study.
Cerebral hyperperfusion syndrome (CHS) is a severe complication of carotid endarterectomy (CEA). Because cerebral hyperperfusion (CH) reduces the benefits of CEA, it is important to identify patients at high risk of developing CH. We investigated dynamic cerebral autoregulation (dCA) as a potential predictor of CH after CEA. ⋯ The lower ipsilateral phase may serve as a predictor of CH after CEA.

The aim of this study was to determine whether patients with syndromic craniosynostosis (SCS) are at increased risk for epilepsy relative to patients with nonsyndromic craniosynostosis (NSCS). ⋯ Syndromic craniosynostosis (SCS) in itself is not a risk factor for epilepsy relative to NSCS. The greater prevalence of hydrocephalus, CM, OSA, ASD, and GERD, all of which were risk factors for epilepsy, in patients with SCS relative to patients with NSCS likely explains the greater prevalence of epilepsy in SCS relative to NSCS.

Older people are particularly at risk for idiopathic normal pressure hydrocephalus (iNPH), a rare neurological condition without known risk factors. Several recent observational studies have reported that gut microbiota composition is associated with iNPH. However, the causal impact of gut microbiota on iNPH is unknown. ⋯ Our findings suggest that certain gut bacteria may enhance iNPH risk. Research is required to determine whether the societal impact of iNPH is lessened in older people by sensible control of their gut microbiota.

The COVID-19 pandemic forced neurosurgery residency application processes to adopt a virtual interview model. This study analyzes the trends in program and applicant residency match behavior due to virtual interviews. ⋯ Despite no change in the overall number of applications submitted per applicant, Black applicants submitted more applications virtually, suggesting potential benefits of virtual format for Black applicants. Interview format was strongly correlated to the use of perceived fitness by applicants in rank decision making. Virtual interviews provide major financial advantages to candidates and could help improve Black representation in neurosurgery. However, they impose limitations on ability access fitness.
