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.

Detection and Evaluation of Procalcitonin Variants As Diagnostic Tools in Systemic Inflammation.
Procalcitonin is an indicator of systemic inflammation associated with major surgery or sepsis. Procalcitonin exists in a full-length and truncated variant as a result of dipeptidylpeptidase-4 (DPP4)-cleavage. We recently identified differential biological activity of both variants. Here, we present an immunoassay-based method for the separate detection of procalcitonin variants and correlation to clinical data in patients with severe systemic inflammation. ⋯ Polyclonal antibodies generated using procalcitonin N-terminal variant peptides as immunogens are suitable for procalcitonin variant assessment. The separate detection of procalcitonin variants may offer additional diagnostic value and can be correlated with organ dysfunction and clinical outcomes in patients with systemic inflammation.

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.
