Randomized Controlled Trial Multicenter Study
Long Term Outcomes of Parenchyma-Sparing and Oncologic Resections in Patients with Non-Functional Pancreatic Neuroendocrine Tumors <3cm in a Large Multi-Center Cohort.
The role of parenchyma-sparing resections (PSR) and lymph node dissection in small (<3 cm) nonfunctional pancreatic neuroendocrine tumors (PNET) is unlikely to be studied in a prospective randomized clinical trial. By combining data from 4 high-volume pancreatic centers we compared postoperative and long-term outcomes of patients who underwent PSR with patients who underwent oncologic resections. ⋯ In small <3 cm nonfunctional PNETs, PSRs and lymph node-sparing resections are associated with lower blood loss, shorter operative times, and lower complication rates when compared to oncologic resections, and have similar long-term oncologic outcomes.

To determine cell-specific gene expression profiles that contribute to development of abdominal aortic aneurysms (AAAs). ⋯ Here we provide the first comprehensive evaluation of single-cell composition of the abdominal aortic wall and reveal how the gene expression landscape is altered in human AAAs.

Studies indicate that coronavirus disease 2019 (COVID-19) infection before or soon after operations increases mortality, but they do not comment on the appropriate timing for interventions after diagnosis. ⋯ Patients undergoing major operations within 8 weeks after a positive test have substantially higher postoperative 90-day mortality than CPT-matched controls without a COVID-19 diagnosis, regardless of presenting symptoms.

The 6-hour threshold to revascularization of an ischemic limb is ubiquitous in the trauma literature, however, contemporary evidence suggests that this threshold should be less. This study aims to characterize the relationship between the duration of limb ischemia and successful limb salvage following lower extremity arterial trauma. ⋯ Limb salvage is critically dependent on the duration of ischemia with a 10% reduction in the probability of successful limb salvage for every hour delay to revascularization. The presence of shock significantly worsens this relationship. Military trauma systems should prioritize rapid hemorrhage control and early limb revascularization within 1 hour of injury.

We sought to assess whether lack of workplace support for clinical work reductions during pregnancy was associated with major pregnancy complications. ⋯ Lack of workplace support for reduction in clinical duties is associated with adverse obstetric outcomes for surgeons. This is a modifiable workplace obstacle that deters surgeons from acting to optimize their infant's and their own health. To ensure the health of expectant surgeons, departmental policies should support reduction of clinical workload in an equitable manner without creating financial penalties, requiring payback for missed call duties, or overburdening colleagues.
