The data revealed significant discrepancies in compensation between genders across all contributing companies. Male neurosurgeons engaged in a higher average number of annual transactions compared with their female counterparts (4.60 vs 2.75, p < 0.001), across various financial interactions. This included a greater participation in royalties and licenses (1.49 vs 0.31, p < 0.001), consulting fees (2.16 vs 1.63, p = 0.024), and acquisitions (0.01 vs 0.00, p = 0.006). On average, female neurosurgeons were compensated $16,303.66, starkly lower than the $75,523.20 average received by their male counterparts (p < 0.005). This gap was especially significant in royalties and licenses, where females earned an average of $5168.57 compared with $61,898.47 for males (p = 0.004). Additionally, in acquisitions, female neurosurgeons received no payments at all, whereas males averaged $2153.43 (p = 0.042).

These disparities highlight the need for systemic changes to address the underlying factors contributing to inequity in compensation and industry collaboration opportunities.

The long-term durability of the treated aneurysms was evaluated by analyzing rebleeding.</p><p><strong>Results: </strong>Poor functional outcomes (modified Rankin Scale score ≥ 3) at discharge were observed in 251 (60.3%) patients. Increasing aneurysm size was significantly associated with poor functional outcomes (OR 1.13, 95% CI 1.04-1.22; p = 0.003) by a multivariable logistic regression analysis, and such negative effects were more prominent in younger patients, those with a good initial neurological grade, and those treated with direct surgery by interaction analyses. Propensity score-based analysis revealed that patients treated with endovascular therapy had a higher chance of better functional outcomes (OR 1.56, 95% CI 1.41-1.71; p = 0.03). Rebleeding 1 year after treatment was more frequent in the endovascular therapy (4.8%) than in the direct surgery (0.0%) group by survival analysis (p = 0.008, log-rank test).</p><p><strong>Conclusions: </strong>Increasing aneurysm size was identified as a risk factor for poor functional outcomes after SAH due to large/giant aneurysms and was affected by the interaction with other conventional risk factors. Endovascular therapy was more likely to be associated with better short-term outcomes; however, a higher delayed rebleeding rate after 1 year was a concern.</p>","PeriodicalId":16505,"journal":{"name":"Journal of neurosurgery","volume":" ","pages":"1-10"},"PeriodicalIF":3.5,"publicationDate":"2025-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142962249","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
