Leading medical schools for female neurosurgery graduates.

OBJECTIVE: The authors sought to determine the medical schools with the highest number and proportion of female graduates currently practicing neurosurgery and to identify medical school characteristics that increase female representation in neurosurgery, with the goal of addressing the gender disparity. METHODS: The authors used the Physician Compare National Downloadable File from the Centers for Medicare & Medicaid Services. Physicians indicating neurosurgery as their primary specialty were extracted. Duplicates, physicians with medical school education listed as "other," and those expected to be in residency, fellowship, or research years (graduation years 2014-2023) were removed. Medical schools with the highest number and proportion of female neurosurgery graduates were stratified. A review of the current literature was conducted to identify characteristics of the institutions with high female representation. RESULTS: A total of 3486 neurosurgeons (319 female [9.2%], 3167 male [90.8%]) were identified. Yale University (n = 12), Columbia University (n = 8), Johns Hopkins University (n = 8), Stanford University (n = 8), and the University of Maryland (n = 8) had the most female neurosurgery graduates. Schools with the highest proportion of female neurosurgery graduates included the University of California, San Diego (25%); the State University of New York Upstate Medical University (25%); Pennsylvania State University (22.2%); the University of Maryland (21.1%); and the University of Florida (18.4%). CONCLUSIONS: Achieving gender diversity in neurosurgery necessitates a multifaceted approach. Institutions with a higher number and proportion of female neurosurgery graduates emphasized female-female mentorship, fostered diversity initiatives, and implemented inclusive policies. To increase female representation in neurosurgery, it is crucial to establish robust mentorship programs that provide aspiring female neurosurgeons with the guidance, support, and motivation required to navigate a traditionally male-dominated field.

In-State Retention Rates of Female Neurosurgery Graduates.

OBJECTIVE: We sought to determine the rate of retaining female neurosurgery graduates in the same states as their medical education and identify medical school and state characteristics associated with high retention rates. METHODS: Database from the Centers for Medicare & Medicaid Services was used to extract female physicians indicating "neurosurgery" as their specialty. The top 25 medical schools with the highest number of female neurosurgery graduates were selected. Descriptive analysis was used to determine the retention rate of female neurosurgery graduates. Univariable and multivariable analyses were used to identify medical school and state characteristics associated with high retention rates. RESULTS: Medical schools with the highest retention rate included the University of California, San Francisco (60%), the University of Alabama (60%), and the University of Pennsylvania (60%). Univariable and multivariable analysis showed the number of female neurosurgery attendings (ß = 0.036, 95% confidence interval [CI] = 0.003 to 0.070, P = 0.04 and ß = 0.036, CI = 0.001 to 0.071, P = 0.04.) and the healthcare employment rate (ß = 0.098, CI = 0.011 to 0.186, P = 0.03 and ß = 0.117, CI = 0.021 to 0.212, P = 0.02) to be positively associated with the retention rate of female neurosurgery graduates. CONCLUSIONS: Retaining female neurosurgery graduates within a state is essential for addressing the physician shortage and gender inequality. To encourage female medical students to practice in the same state, medical schools and states should work collectively to improve the visibility of female neurosurgeons and increase employment opportunities.

Women in Neurosurgery: Trends in the United States.

OBJECTIVE: We sought to identify trends in the number of female neurosurgeons across each state and identify state characteristics that affect such values. METHODS: The Physician Compare National Downloadable File was queried from the Center for Medicare & Medicaid Services for 2017 and 2023. Physicians indicating "neurosurgery" as their primary specialty were extracted and duplicates were removed. States were ranked based on the number of female neurosurgeons. The percent growth in the number of female neurosurgeons from 2017 to 2023 was calculated for each state. Univariable and multivariable regressions were used to identify the association between state characteristics and the number of female neurosurgeons. RESULTS: The number of female neurosurgeons was higher in urban states while rural states saw a greater increase compared to five years ago. Univariable regression showed significant differences in the number of neurosurgery residency programs, neurosurgery hospitals ranked in U.S. News & World Report, paid parental leave law, number and percentage of female physicians, and diversity index score (P < 0.05). The diversity index score independently affected the number of female neurosurgeons (P < 0.05). CONCLUSIONS: States with more training programs, female physicians, and paid parental leave policies saw a large number of female neurosurgeons. Diversity in the general population is also crucial to improving the equity in gender representation of neurosurgeons in each state. The increase in female neurosurgery representation in rural states shows that the shortage of neurosurgeons in underserved areas is creating a unique niche for female neurosurgeons to excel.

Surgical Outcomes in Octogenarians with Central Cord Syndrome: A Propensity-Score Matched Analysis.

OBJECTIVE: Central cord syndrome (CCS) is a traumatic cervical spine injury that is treated with surgical decompression. In octogenarians (80-89), surgeons often opt for conservative management instead due to fears of postoperative complications and prolonged recovery times. This study aims to assess the in-hospital complications and outcomes in octogenarians undergoing surgery compared to those undergoing nonsurgical management for CCS. METHODS: The National Trauma Data Bank was queried from 2017 to 2019 for octogenarians with CCS. Patients who received surgical fusion or decompression were divided into the surgery group and the remaining into the nonsurgical group. The surgery group was sampled and propensity score matched with the non-surgery group. Student t tests and Pearson χ2 tests were used to test for group differences. RESULTS: A total of 759 octogenarians with CCS were identified. Following sampling and propensity score matching, 225 patients were identified in each group. The surgery group experienced longer intensive care unit (6.8 days vs. 3.21 days, P < 0.001) and hospital (13.79 days vs. 7.8 days, P < 0.001) lengths of stay and higher rates of deep vein thrombosis (4.89% vs. 0.44%, P = 0.02) and ventilator-associated pneumonia (4% vs. 0%, P = 0.02). Patients did not otherwise differ in mortality rate, other hospital complications, and discharge disposition. CONCLUSIONS: Octogenarians undergoing surgery for CCS experience longer length of stay and complications consistent with prolonged hospitalization but otherwise have similar mortality, hospital complications, and discharge disposition compared to non-surgical treatment. Given the relative lack of short-term drawbacks, surgery should be considered first-line management when the long-term benefits are substantive.

DNAzyme Cleavage of CAG Repeat RNA in Polyglutamine Diseases.

CAG repeat expansion is the genetic cause of nine incurable polyglutamine (polyQ) diseases with neurodegenerative features. Silencing repeat RNA holds great therapeutic value. Here, we developed a repeat-based RNA-cleaving DNAzyme that catalyzes the destruction of expanded CAG repeat RNA of six polyQ diseases with high potency. DNAzyme preferentially cleaved the expanded allele in spinocerebellar ataxia type 1 (SCA1) cells. While cleavage was non-allele-specific for spinocerebellar ataxia type 3 (SCA3) cells, treatment of DNAzyme leads to improved cell viability without affecting mitochondrial metabolism or p62-dependent aggresome formation. DNAzyme appears to be stable in mouse brain for at least 1 month, and an intermediate dosage of DNAzyme in a SCA3 mouse model leads to a significant reduction of high molecular weight ATXN3 proteins. Our data suggest that DNAzyme is an effective RNA silencing molecule for potential treatment of multiple polyQ diseases.
