The Glass Ceiling in Global Health: Perspectives of Female and Male Anesthesiologists.
Gender equity is essential for improving health outcomes globally. Despite comprising 75% of the global health workforce and dominating academic global health programs, women remain underrepresented in leadership positions in global health organizations. Our study aimed to identify potential gender differences in the beliefs and attitudes regarding barriers that women anesthesiologists encounter in pursuing careers and leadership roles in global health and to identify recommendations for improving gender equity in global health. ⋯ Gender disparities exist in the pursuit of global health careers. This study underscored that more women than men perceive barriers in pursuing leadership roles in global health and that men generally encounter these obstacles to a lesser extent. Female representation in leadership positions could be supported through evidence-informed policies that promote work-life balance, improve mentorship, offer equal opportunities for career advancement and adequate pay, and combat gender-based discrimination.

Neurological Complications After Transcatheter Aortic Valve Replacement: A Review.
Transcatheter aortic valve replacement (TAVR) has become the dominant procedural modality for aortic valve replacement in the United States. The reported rates of neurological complications in patients undergoing TAVR have changed over time and are dependent on diagnostic definitions and modalities. Most strokes after TAVR are likely embolic in origin, and the incidence of stroke has decreased over time. ⋯ In this narrative review, we summarize the available data on the incidence of stroke, delirium, and cognitive decline after TAVR and highlight potential areas in need of future research. We also discuss silent cerebral ischemic lesions (SCILs) and their association with a decline in postoperative neurocognitive status after TAVR. Finally, we describe that the risk of delirium and postoperative decline is increased when nonfemoral access routes are used, and we highlight the need for standardized imaging and valid, repeatable methodologies to assess cognitive changes after TAVR.

Direct Reinfusion of Unwashed Shed Autologous Blood During Thoracoabdominal Aortic Aneurysm Repair: A Retrospective Analysis.
This study's purpose was to assess whether larger volumes of reinfused unwashed shed autologous blood (SAB) were associated with adverse events within 30 days for patients undergoing open thoracoabdominal aortic aneurysm (TAAA) repair. During TAAA repair, our institution uses a system wherein SAB is filtered, but not washed or centrifuged, and then returned to the patient via a rapid-infusion device. By reinfusing SAB, the system preserves the patient's autologous whole blood and may reduce the number of allogenic transfusions required during TAAA repair, but the end-organ effects of reinfusing unwashed SAB have not been extensively evaluated. ⋯ For patients undergoing open TAAA repair, larger reinfusion volumes of unwashed SAB were not associated with greater odds of major early postoperative complications.

Assisted Fluid Management and Sublingual Microvascular Flow During High-Risk Abdominal Surgery: A Randomized Controlled Trial.
Implementation of goal-directed fluid therapy (GDFT) protocols remains low. Protocol compliance among anesthesiologists tends to be suboptimal owing to the high workload and the attention required for implementation. The assisted fluid management (AFM) system is a novel decision support tool designed to help clinicians apply GDFT protocols. This system predicts fluid responsiveness better than anesthesia practitioners do and achieves higher stroke volume (SV) and cardiac index values during surgery. We tested the hypothesis that an AFM-guided GDFT strategy would also be associated with better sublingual microvascular flow compared to a standard GDFT strategy. ⋯ Use of an AFM-guided GDFT strategy resulted in higher sublingual microvascular flow during surgery compared to use of a standard GDFT strategy. Future trials are necessary to make conclusive recommendations that will change clinical practice.

Effect of In Vivo Administration of Fibrinogen Concentrate Versus Cryoprecipitate on Ex Vivo Clot Degradation in Neonates Undergoing Cardiac Surgery.
Neonates undergoing cardiac surgery require fibrinogen replacement to restore hemostasis after cardiopulmonary bypass (CPB). Cryoprecipitate is often the first-line treatment, but recent studies demonstrate that fibrinogen concentrate (RiaSTAP; CSL Behring) may be acceptable in this population. This investigator-initiated, randomized trial compares cryoprecipitate to fibrinogen concentrate in neonates undergoing cardiac surgery (ClinicalTrials.gov NCT03932240). The primary end point was the percent change in ex vivo clot degradation from baseline at 24 hours after surgery between groups. Secondary outcomes included intraoperative blood transfusions, coagulation factor levels, and adverse events. ⋯ Neonates who received fibrinogen concentrate, as compared to cryoprecipitate, have similar perioperative ex vivo clot degradation with faster degradation at 24 hours postsurgery, less post-CPB blood transfusions, and no increased bleeding or thrombotic complications. Our findings suggest that fibrinogen concentrate adequately restores hemostasis and reduces transfusions in neonates after CPB without increased bleeding or thrombosis risk.
