Recruitment of women in neurosurgery: a 7-year quantitative analysis.
The authors aimed to characterize which US medical schools have the most female neurosurgery residents and to identify potential associations between medical school characteristics and successful recruitment of women pursuing a neurosurgery career. ⋯ This study characterizes which medical schools are most successful at recruiting female students who constituted the total neurosurgery resident workforce of the 2020-2021 academic year. The overall number of clinical neurosurgery faculty rather than faculty gender was independently associated with female recruitment. Gender differences in research productivity persisted with control for confounders and increased between preresidency and 2021 time points. Such understanding of factors that influence the recruitment of women can help improve female representation in neurosurgery residency training moving forward.

The profile of cognitive impairment and hemodynamic compromise in moyamoya: a single-center prospective cohort study.
Patients with moyamoya vasculopathy often experience cognitive impairments. In this prospective single-center study, the authors investigated the profile of neurocognitive impairment and its relation with the severity of ischemic brain lesions and hemodynamic compromise. ⋯ In this Western cohort, cognitive functioning in patients with moyamoya vasculopathy was below the population norm, and 73% had cognitive impairment in at least one domain. The cognitive profile differed between adults and children. The authors could not find an association with imaging findings.

Effect of endovascular treatment within 6 hours for acute basilar artery occlusion.
The aim of this study was to investigate the efficacy and safety of endovascular treatment (EVT) plus standard medical treatment (SMT) in patients with acute basilar artery occlusion (BAO) within 6 hours of the estimated occlusion time, based on a Chinese population. ⋯ Based on the study design, patients with acute BAO who received EVT within 6 hours were associated with improved favorable outcome and decreased deaths compared with patients who received SMT. Predictors of desirable outcome in patients undergoing EVT included lower age, lower baseline National Institutes of Health Stroke Scale score, higher baseline posterior circulation Alberta Stroke Program Early CT Score, absence of diabetes mellitus, and modified Thrombolysis in Cerebral Infarction scores 2b-3.

Pineal cyst: results of long-term MRI surveillance and analysis of growth and shrinkage rates.
Pineal cyst (PC) is a relatively common true cyst in the pineal gland. Its long-term natural course remains ill defined. This study aims to evaluate the long-term natural history of PC and examine MRI risk factors for cyst growth and shrinkage to help better define which patients might benefit from surgical intervention. ⋯ Only 5% of PCs, mainly in patients younger than 50 years of age, have the potential to grow, while cyst shrinkage is more likely to occur across all age groups. Younger age is associated with cyst growth, while larger diameter and higher signal intensity on T2-weighted imaging are associated with shrinkage. Surgery is rarely needed for PCs, despite the possibility of a certain degree of growth.

Comparison of the impact of skull density ratio with alternative skull metrics on magnetic resonance-guided focused ultrasound thalamotomy for tremor.
One of the key metrics that is used to predict the likelihood of success of MR-guided focused ultrasound (MRgFUS) thalamotomy is the overall calvarial skull density ratio (SDR). However, this measure does not fully predict the sonication parameters that would be required or the technical success rates. The authors aimed to assess other skull characteristics that may also contribute to technical success. ⋯ The authors compared a number of skull metrics against SDR and showed that SDR was one of the best indicators of treatment parameters when used alone. In addition, a number of other machine learning algorithms are proposed that may be explored to improve its accuracy when additional data are obtained. Additional metrics related to eventual sonication parameters should also be identified and explored.
