Multicenter Study Observational Study
COVID-19 Vaccination Associated with Reduced Post-Operative SARS-CoV-2 Infection and Morbidity.
The purpose of this study was to determine the effect of COVID-19 vaccination on postoperative mortality, pulmonary and thrombotic complications, readmissions and hospital lengths of stay among patients undergoing surgery in the United States. ⋯ COVID-19 vaccination is associated with lower rates of postoperative morbidity. The benefit is most pronounced among individuals who have never had a COVID-19 infection before surgery.

The gold standard of safe-guarding the quality of published science is peer review. However, this long-standing system has not evolved in today's digital world, where there has been an explosion in the number of publications and surgical journals. A journal's quality depends not only on the quality of papers submitted but is reflected upon the quality of its peer review process. ⋯ This review identifies the potential causes of the peer-review crisis, outlines the incentives and drawbacks of being a reviewer, summarizes the currently established common practices of rewarding reviewers and the existing and potential solutions to the problem. The magnitude of the problem and unsustainability that will make it perish are discussed along with its current flaws. Finally, recommendations are made to address many of the weaknesses of the system with the hope to revive it.

Evaluating the perioperative outcomes of minimally invasive (MIV) donor hepatectomy for adult live donor liver transplants in a large multi-institutional series from both Eastern and Western centers. ⋯ This study shows favorable early postoperative outcomes in more than 400 MIV donor hepatectomy from 10 experienced centers. These results are comparable to those of benchmarking series of open standard donor hepatectomy.

Observational Study
Changes in Smoking Behavior Before and After Gastric Bypass: A 7-year Study.
To evaluate smoking history and change in smoking behavior, from 1 year before through 7 years after Roux-en-Y gastric bypass (RYGB) surgery, and to identify risk factors for post-surgery smoking. ⋯ Although most adults who smoked 1-year before RYGB quit pre-surgery, smoking prevalence rebounded across 7-years, primarily due to relapse.

To assess metabolic dysfunctions and steatohepatosis after standard and local pancreatic resections for benign and premalignant neoplasms. ⋯ Standard pancreatic resections for benign tumor carry a considerable high risk for a new onset of diabetes, pancreatic exocrine insufficiency and following PD for steatohepatosis. Parenchyma-sparing, local resections are associated with low grade metabolic dysfunctions.
