Multicenter Study
Patient Behaviors and Characteristics Related to Weight Regain After Roux-en-Y Gastric Bypass: A Multicenter Prospective Cohort Study.
To identify patient behaviors and characteristics related to weight regain after Roux-en-Y gastric bypass surgery (RYGB). ⋯ Several behaviors and characteristics associated with greater weight regain were identified, which inform integrated healthcare approaches to patient care and identify high-risk patients to improve long-term weight loss maintenance after RYGB.

Multicenter Study
Histopathologic Predictors of Survival and Recurrence in Resected Ampullary Adenocarcinoma: International Multicenter Cohort Study.
The aim of the study was to define histopathologic characteristics that independently predict overall survival (OS) and disease-free survival (DFS), in patients who underwent resection of an ampullary adenocarcinoma with curative intent. ⋯ Independent predictors of OS in resected ampullary cancer were N-stage, perineural invasion, and adjuvant chemotherapy. N-stage was the only predictor of DFS. These findings improve predicting survival and recurrence after resection of ampullary adenocarcinoma.

To describe variability in and consequences of opioid prescriptions following pediatric laparoscopic appendectomy. ⋯ There was substantial variation in opioid prescribing patterns. Opioid prescription duration increased risk of ED visits for constipation, but not for pain or refill.

The aim of this study was to define whether rapidly reallocating health care workers not experienced with PP for performing PP in ICU is feasible and safe. ⋯ To overcome the surge of critically ill COVID-19 patients, reallocating health care workers to targeted medical tasks beyond their respective expertise such as PP was safe.

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.
