The aim of this study was to determine the sensitivity and specificity of potential thresholds of alcohol use for identifying alcohol-related problems in women post-Roux-en-Y gastric bypass (RYGB). ⋯ The sensitivity and specificity of these thresholds indicate assessment of alcohol consumption alone may be inadequate for identifying women at risk for alcohol-related problems post-RYGB. Additional screening tools for alcohol-related problems, which assess symptoms of alcohol-related problems, should be conducted in this population.

This study aimed to identify the empirical processes and evidence that expert surgical teachers use to determine whether to take over certain steps or entrust the resident with autonomy to proceed during an operation. ⋯ Expert surgical teachers' 3-phase process of decisions on take-over provides a potential framework that may help surgeons identify appropriate opportunities to develop residents' progressive autonomy by engaging the resident in the determination of entrustability before deciding to take over.

Conflicting reports exist regarding whether patients undergoing surgery on the weekend or later in the week experience worse outcomes. ⋯ We found no evidence of a weekend effect for ruptured or symptomatic AAA repair. However, patients with ruptured AAA transferred on the weekend experienced higher mortality than those transferred during the week, suggesting a need for improvement in weekend transfer processes.

Assess the accuracy of 3 early warning scores for predicting severe adverse events in postoperative inpatients. ⋯ Early warning scores are predictive of severe adverse events in postoperative patients. eCART is significantly more accurate in this patient population than both NEWS and MEWS.

To establish an evidence-based cut-off to differentiate between early and late recurrence and to compare clinicopathologic risk factors between the two groups. ⋯ A recurrence-free interval of 12 months is the optimal threshold for differentiating between early and late recurrence, based on subsequent prognosis.
