Epidemiologic studies have shown that individuals who consume low to moderate alcohol have a lower risk of cardiovascular disease developing compared with abstainers. Although experimental studies confirmed this observation, the effect of alcohol on ischemic myocardium is still unclear. We developed a clinically relevant animal model of chronic myocardial ischemia to investigate the effects of moderate alcohol consumption on the myocardium. ⋯ Alcohol consumption down-regulates apoptosis and promotes cell survival in the ischemic and nonischemic myocardium. Alcohol also modulates MTOR signaling, which regulates senescence and apoptosis. Perhaps MTOR and apoptosis regulation is another mechanism by which moderate EtOH consumption is cardioprotective.

There is currently no systematic approach to evaluating the severity of intraoperative adverse events (iAEs). ⋯ We propose a novel iAE severity classification system with high internal consistency and solid construct validity. Our classification scheme might prove essential for benchmarking quality of intraoperative care across hospitals and/or individual surgeons.

The incidence of, and associated risk factors for, readmission after potentially curative gastrectomy for patients with gastric cancer has not been well studied. We sought to determine the 30-day readmission rate as well as the potential risk factors for readmission at our institution in patients undergoing gastrectomy for gastric cancer with curative intent. ⋯ Readmission after potentially curative gastrectomy for gastric cancer is common. Patients with pre-existing cardiovascular disease, those who suffer major postoperative complications, and those undergoing total gastric resections are at especially high risk for readmission, and strategies designed to support these high-risk patients on discharge are warranted.

A minority of liver transplantation (LT) candidates pursue listing at multiple centers to achieve transplantation. The purpose of this study was to assess the characteristics and outcomes of the migrated LT candidates, that is, those who travel to secondary centers seeking LT. ⋯ A small and distinctive cohort of LT recipients pursue migration to achieve transplantation. Travel patterns of migrated LT recipients appear to reflect the ongoing geographic disparities in liver distribution and underscore the need for alterations in policy to allow for equitable distribution.

Minimally invasive Ivor Lewis esophagectomy (MIE) is gaining popularity for the treatment of esophageal cancer. However, as it is a technically demanding operation, a learning curve should be defined to guide training and allow implementation at institutions not currently using this technique. ⋯ Improved operative and perioperative parameters for MIE were observed in the last 40 patients when compared with the first 40 patients. A reasonable learning curve for MIE would require the operation and perioperative care of 35 to 40 patients.
