To overcome persistent gender disparities in academic surgery, it is critical to examine the earliest phase of surgical training. This national study sought to assess whether gender disparities also existed among surgical interns, as a proxy for medical school research experience in both quantity and quality. ⋯ Gender disparities existed in the quality of research experience in the earliest phase of surgical training. These timely results call for additional interventions by the stakeholders of graduate medical education.

Surgical intervention remains the cornerstone of a multidisciplinary approach in the treatment of colorectal liver metastases (CLM). Nevertheless, patient outcomes vary greatly. While predictive tools can assist decision-making and patient counseling, decades of efforts have yet to result in generating a universally adopted tool in clinical practice. ⋯ Machine learning provides powerful tools to create predictive models of survival and recurrence after surgery for CLM. The effectiveness of both machine learning models varies, but on most occasions, GBT outperforms LRB. Prospective validation of these models lays the groundwork to adopt them in clinical practice.

Although strong evidence exists for combined mechanical and oral antibiotic bowel preparation before elective colorectal resection, the utility of preoperative bowel preparation for patients undergoing sigmoid resection after endoscopic decompression of sigmoid volvulus has not been previously examined. The goal of this study was to evaluate the association between bowel preparation and postoperative outcomes for patients undergoing semielective, same-admission sigmoid resection for acute volvulus. ⋯ This study demonstrates a significant benefit for complete bowel preparation before semielective, same-admission sigmoid resection in patients with acute sigmoid volvulus. However, only a small percentage of patients in this national sample underwent complete preoperative bowel preparation. Broader adoption of bowel preparation may reduce overall rates of complication in patients who require sigmoid colectomy due to volvulus.

Preoperative opioid use has shown association with worse outcomes after surgery. However, little is known about the effect of preoperative benzodiazepines with and without opioids. The aim of this study was to determine the influence of preoperative substance use on outcomes after abdominal surgery. ⋯ Preoperative opioid and benzodiazepine use are independent risk factors that contribute to postoperative morbidity. This influence on surgical outcomes is exacerbated when patients are on both substances.

Use of whole-body CT scan (WBCT) is widespread in the evaluation of traumatically injured patients and may be associated with improved survival. WBCT protocols include the use of IV contrast unless there is a contraindication. This study tests the hypothesis that using plain WBCT scan during the global contrast shortage would result in greater need for repeat contrast-enhanced CT, but would not impact mortality, missed injuries, or rates of acute kidney injury (AKI). ⋯ Trauma imaging practices at our center changed during the global contrast shortage; the use of contrast decreased despite the frequency of trauma WBCT scans remaining the same. The rates of AKI and RRT did not change, suggesting that WBCT with contrast is insufficient to cause AKI. The missed injury rate was equivalent. Our data suggest similar outcomes can be achieved with selective IV contrast use during WBCT.
