To understand and overcome the challenges associated with moving life-urgent payloads using unmanned aircraft. ⋯ Here, we completed the first successful delivery of a human organ using unmanned aircraft. This study brought together multidisciplinary resources to develop, build, and test the first organ drone system, through which we performed the first transplant of a drone transported kidney. These innovations could inform not just transplantation, but other areas of medicine requiring life-saving payload delivery as well.

Observational Study
Pre-transplant T-cell Clonality: An Observational Study of a Biomarker for Prediction of Sepsis in Liver Transplant Recipients.
This study investigated the ability of pre-transplant T-cell clonality to predict sepsis after liver transplant (LT). ⋯ T-cell repertoire clonality is a novel biomarker predictor of sepsis before development of clinical symptoms. Early sepsis monitoring and management may reduce post-LT mortality. These findings have implications for developing sepsis-prevention protocols in transplantation and potentially other populations.

To understand the impact of Black race on breast cancer (BC) presentation, treatment, and survival among Hispanics. ⋯ In this first comprehensive analysis of HB and HW, HB have worse OS compared to HW, suggesting that race/ethnicity is a complex variable acting as a proxy for tumor and host biology, as well as individual and neighborhood-level factors impacted by structural racism. This study identifies markers of vulnerability associated with Black race and markers of resiliency associated with Hispanic ethnicity to narrow a persistent BC survival gap.

Randomized Controlled Trial Multicenter Study
Early Prehospital Tranexamic Acid Following Injury is Associated with a 30-day Survival Benefit: A Secondary Analysis of a Randomized Clinical Trial.
We sought to characterize the timing of administration of prehospital tranexamic acid (TXA) and associated outcome benefits. ⋯ Administration of prehospital TXA within 1 hour from injury in patients at risk of hemorrhage is associated with 30-day survival benefit, lower incidence of multiple organ failure, and lower transfusion requirements.

Multicenter Study
Molecular Genomic Assessment using a blood-based mRNA signature (NETest) is Cost Effective and Predicts Neuroendocrine Tumor Recurrence with 94% accuracy.
Identification of residual disease after neuroendocrine tumor (NET) resection is critical for management. Post-surgery imaging is insensitive, expensive, and current biomarkers ineffective. We evaluated whether the NETest, a multigene liquid biopsy blood biomarker, correlated with surgical resection and could predict recurrence. ⋯ NETest diagnosis is more accurate than CgA (100% vs 22%). Surgery significantly decreased NETest. An elevated POD30 NETest predicted recurrence with 94% accuracy and post-surgical POD30 NETest follow-up stratification decreased costs by 42%. CgA had no surgical utility. Further studies would define the accuracy and cost-effectiveness of the NETest in the detection of postoperative recurrent disease.
