Resuming Anticoagulants in Patients With Intracranial Hemorrhage: A Meta-Analysis and Literature Review.

BACKGROUND AND OBJECTIVES: Intracerebral hemorrhage (ICH) is one of the most disabling cerebrovascular events. Several studies have discussed oral anticoagulant (OAC)-related ICH; however, the optimal timing of resuming OAC in patients with ICH is still a dilemma. In this literature review/meta-analysis, we will summarize, discuss, and provide the results of studies pertaining to OAC resumption in patients with ICH. METHODS: Using PubMed, Ovid Medline, and Web science, a systemic literature review was performed in accordance with the Preferred Reporting Items for Systemic Reviews and Meta-Analyses statement on December 20, 2022. Inclusion criteria for the meta-analysis were all studies reporting mean, median, and standard deviation for the duration of anticoagulants resumption after ICH. Thirteen studies met the above criteria and were included in the meta-analysis. RESULTS: Of the 271 articles found in the literature, pooled analysis was performed in 13 studies that included timing of OAC resumption after ICH. The pooled mean duration to OAC resumption after the index ICH was 31 days (95% CI: 13.7-48.3). There was significant variation among the mean duration to OAC resumption reported by the studies as observed in the heterogeneity test ( P -value ≈0). CONCLUSION: Based on our meta-analysis, the average time of resuming OAC in patients with ICH is around 30 days. Several factors including the type of intracranial hemorrhage, the type of OAC, and the indication for OACs should be taken into consideration for future studies to try and identify the best time to resume OAC in patients with ICH.

Women in neurosurgery: a cross-sectional demographic study of female neurosurgery residents in the United States.

OBJECTIVE: Over the past several decades, the number of women applying to medical school has increased significantly. However, parallel recruitment and retention of women in the field of neurosurgery continues to lag. The aim of this study was to identify the ratio and trend of female neurosurgery residents to the total number of residents during the past 7 years across all US neurosurgery residency programs. METHODS: The authors conducted a cross-sectional demographic study investigating the ratio of female neurosurgery residents to the total number of neurosurgery residents across US neurosurgical programs from 2016 to 2022. Using the Fellowship and Residency Electronic Interactive Database, all neurosurgical residency programs in the US were collected. Data were further divided into postgraduate years 1-7 to dissect the data collection per residency year. One hundred fourteen programs were included in the study. RESULTS: The number of female neurosurgery residents was 71 (29.8%) in 2022, 58 (25.2%) in 2021, 65 (27.9%) in 2020, 62 (27.3%) in 2019, 46 (21.4%) in 2018, 33 (15.2%) in 2017, and 34 (15.9%) in 2016. The trend line showed a significant increase using the Mann-Kendall test (p = 0.035). The total number of international medical graduate (IMG) female neurosurgery residents was 3 (4.2%) in 2022, 4 (6.9%) in 2021, 3 (4.6%) in 2020, 1 (1.6%) in 2019, 1 (2.2%) in 2018, 1 (3%) in 2017, and 2 (5.9%) in 2016. CONCLUSIONS: The number of women matching into neurosurgery residency programs is modestly increasing, especially for IMG women. Future steps toward fewer gender disparities should focus on career advancement and leadership diversification in organized and academic neurosurgery.
