Comparative Study
Utilizing Machine Learning Methods for Preoperative Prediction of Postsurgical Mortality and Intensive Care Unit Admission.
To compare the performance of machine learning models against the traditionally derived Combined Assessment of Risk Encountered in Surgery (CARES) model and the American Society of Anaesthesiologists-Physical Status (ASA-PS) in the prediction of 30-day postsurgical mortality and need for intensive care unit (ICU) stay >24 hours. ⋯ Machine learning can be used to improve surgical risk prediction compared to traditional risk calculators. AUPRC should be used to evaluate model predictive performance instead of AUROC when the dataset is imbalanced.

The aim of the study was to determine the prognostic impact of co-existence of APC and PIK3CA mutations in patients undergoing preoperative chemotherapy and resection for colorectal liver metastases (CLM). ⋯ Double mutation of APC and PIK3CA predicts inferior response to preoperative chemotherapy and poor survival in patients with CLM.

To comprehensively assess the level of achievement and demographics of national surgical society presidents. ⋯ The ACS and ASA presidents' CVs displayed unsurpassed scholastic achievement, and although not equivalent, both the AWS and the SBAS presidents had comparable attainment. These findings further substantiate that women and ethnic minority surgeons are deserving of additional national leadership consideration as organized medicine pursues a more diverse and reflective physician workforce.

Comparative Study
The Impact of Telemedicine Adoption on a Multidisciplinary Bariatric Surgery Practice During the COVID-19 Pandemic.
This study aims to show how full-time telemedicine adoption has impacted patient visit volume and attendance in a comprehensive metabolic and weight loss center. ⋯ Although new patient visit volume fell across the board, follow-up visits increased for certain nonsurgical providers. This provides a template for adoption of a multidisciplinary telehealth clinic in a post-pandemic world.

Comparative Study
Stereotactic Body Radiotherapy Versus Delayed Surgery for Early-stage Non-small-cell Lung Cancer.
To evaluate the overall survival of patients with operable stage IA non-small-cell lung cancer (NSCLC) who undergo "early" SBRT (within 0-30 days after diagnosis) versus "delayed" surgery (90-120 days after diagnosis). ⋯ In this national analysis, for patients with stage IA NSCLC, extended delay of surgery was associated with improved survival when compared to early treatment with SBRT.
