The purpose of this study is to determine preoperative factors that are predictive of malignancy in patients undergoing pancreatic resection for intraductal papillary mucinous neoplasms (IPMN). ⋯ In agreement with current IPMN management guidelines, we found MPD dilatation, even low levels from 5 mm to 9.9 mm, to be the single best predictor of HG-IPMN or invasion, highlighting the critical role that MPD plays in the selection of surgical candidates.

Laparoscopic Liver Transplantation: Dream or Reality? The First Step With Laparoscopic Explant Hepatectomy.
To introduce the laparoscopic approach in liver transplant recipients. ⋯ This case study suggests that the hybrid approach may be feasible and safe in selected recipients. The decision to use this surgical approach should be made in transplant centers with significant expertise in both laparoscopic liver and pancreatic surgery. Further reducing the size of the abdominal incision is the next step, which may be achieved with the development of vascular anastomoses devices.

Metabolic Systems Analysis of Shock-Induced Endotheliopathy (SHINE) in Trauma: A New Research Paradigm.
Investigate the endothelial cell phenotype (s) that causes Shock-Induced Endotheliopathy in trauma. ⋯ We confirm that trauma patients have a significantly different metabolic profile compared with controls. A minimum of 4 shock-induced endotheliopathy phenotypes were identified, which were independent of syndecan-1level (except 1 phenotype) verifying that the endothelial response to trauma is heterogeneous and most likely driven by a genetic component. Moreover, we introduced a new research tool in trauma by using metabolic systems biology, laying the foundation for personalized medicine.

The Risk Analysis Index (RAI) predicts 30-, 180-, and 365-day mortality based on variables constitutive of frailty. Initially validated, in a single-center Veteran hospital, we sought to improve model performance by recalibrating the RAI in a large, veteran surgical registry, and to externally validate it in both a national surgical registry and a cohort of surgical patients for whom RAI was measured prospectively before surgery. ⋯ The RAI-rev has improved discrimination and calibration as a frailty-screening tool in surgical patients. It has robust external validity in men and women across a wide range of surgical settings and available for immediate implementation for risk assessment and counseling in preoperative patients.

To develop a prediction model for clinical outcomes after unilateral adrenalectomy for unilateral primary aldosteronism. ⋯ The predictive score and the primary aldosteronism surgical outcome predictor can be used in a clinical setting to differentiate patients who are likely to be clinically cured after surgery from those who will need continuous surveillance after surgery due to persistent hypertension.
