RESUMEN

BACKGROUND: Although acute kidney injury (AKI) has been established as an independent risk factor for in-hospital mortality for patients on veno-arterial (V-A) extracorporeal membranous oxygenation (ECMO), the impact of Kidney Disease Improving Global Outcomes (KDIGO) stages of AKI has yet to be elucidated as a risk factor. METHODS: We conducted a retrospective analysis of patient outcomes based on KDIGO stages of AKI at a single institution. The analysis was a cohort of 179 patients; 66 without AKI, 19 with stage 1 AKI, 18 with stage 2 AKI, and 76 with stage 3 AKI. RESULTS: Every 1-year increase in age was associated with 4% increased odds of mortality at 30 days (95% confidence interval [CI] 1.01, 1.07; p = 0.004). The presence of AKI at any stage was associated with 59% increased odds of 30-day mortality (95% CI 0.81, 3.10; p = 0.176). The presence of stage 1 AKI was associated with a 5% decreased odds of 30-day mortality (95% CI 0.32, 2.89). The presence of stage 2 AKI (odds ratio [OR] 2.29, 95% CI 0.69, 7.55; p = 0.173) and stage 3 AKI (OR 1.68, 95% CI 0.81, 3.46; p = 0.164) was associated with increased odds of 30-day mortality. CONCLUSION: Based on our single-center study, higher KDIGO stages of AKI likely have increased odds of mortality at 30 days. Larger studies are needed to confirm these findings.

RESUMEN

OBJECTIVES: Stroke after thoracic aortic surgery is a complication that is associated with poor outcomes. The aim is to characterize the intraoperative risk factors for stroke development. DESIGN: A retrospective analysis. SETTING: Tertiary, high-volume cardiac surgery center. PARTICIPANTS: Patients who had surgical repair of thoracic aortic diseases from January 1, 2017, through December 31, 2021. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: A total of 704 patients were included, of whom 533 had ascending aortic aneurysms, and 171 had type A aortic dissection. The incidence of postoperative stroke was 4.5% (95% CI 2.9%-6.6%) for ascending aortic aneurysms compared with 12.3% (95% CI 7.8%-18.16%) in type-A aortic dissections. Patients who developed postoperative strokes had significantly lower intraoperative hemoglobin median (7.5 gm/dL [IQR 6.8-8.6] v 8.55 gm/dL [IQR 7.3-10.0]; p < 0.001). The median cardiopulmonary bypass time was 185 minutes (IQR 136-328) in the stroke group versus 156 minutes (IQR 113-206) in the nonstroke group (p = 0.014). Circulatory arrest was used in 57.8% versus 38.5% of the nonstroke patients (p = 0.017). The initial temperature after leaving the operating room was lower, with a median of 35.0°C (IQR 34-35.92) in the stroke group versus 35.5°C (IQR 35-36) in the nonstroke cohort (p = 0.021). CONCLUSIONS: This single-center study highlighted the potential importance of intra-operative factors in preventing stroke. Lower hemoglobin, longer duration of cardiopulmonary bypass, deep hypothermic circulatory arrest, and postoperative hypothermia are potential risk factors for postoperative stroke. Further studies are needed to prevent this significant complication in patients with thoracic aortic diseases.

RESUMEN

BACKGROUND: Despite a significant growth of women trainees in cardiothoracic surgery recently, women remain a minority of cardiothoracic surgeons and hold a minority of leadership positions. This study evaluates differences in cardiothoracic surgeon subspecialty choices, academic rank, and academic productivity between men and women. METHODS: The Accreditation Council for Graduate Medical Education database was used to identify 78 cardiothoracic surgery academic programs in the United States, including integrated, 4+3, and traditional fellowships, as of June 2020. A total of 1179 faculty members were identified within these programs, 585 adult cardiac surgeons (50%), 386 thoracic surgeons (33%), and 168 congenital surgeons (14%), and other, 40 (3%). Data were collected using institutional websites, ctsnet.org, doximity.com, linkedin.com, and Scopus. RESULTS: Of the 1179 surgeons, only 9.6% were women. Overall, women composed 6.7% of adult cardiac, 15% of thoracic, and 7.7% of congenital surgeons. Among subspecialties, women represent 4.5% (17 of 376) of full professors and 5% (11 of 195) of division chiefs in cardiothoracic surgery in the United States, have shorter career durations, and lower h-indices compared with men. However, women had similar m-indices, which factors in career length, compared with men in adult cardiac (0.63 vs 0.73), thoracic (0.77 vs 0.90), and congenital (0.67 vs 0.78) surgeons. CONCLUSIONS: Career duration, including cumulative research productivity, appears to be the most important factors predicting full professor rank, potentially contributing to persistent sex-based disparities in academic cardiothoracic surgery.
