To evaluate existing federal survey data infrastructure pertaining to firearms and firearm-related violence. ⋯ Reliable national data are critical to understanding firearm-related violence as well as to developing, implementing, and evaluating public health measures to address it. Improving the consistency of questions pertaining to firearm access and experiences of violence in federal surveys offers an opportunity to improve national data infrastructure.

This study aimed to validate the prognostic significance of stratification using pathological stage and response to neoadjuvant chemotherapy with a nationwide database from an authorized institute by the Japan Esophageal Society. ⋯ The prognostic value of classification using pStage and the pathological response was successfully validated using real-world data in Japan. This result would guide appropriate treatment for patients with esophageal squamous cell carcinoma who received neoadjuvant chemotherapy followed by esophagectomy.

To develop a machine learning model that automatically quantifies the spread of blood in the surgical field using intraoperative videos of laparoscopic colorectal surgery and evaluate whether the index measured with the developed model can be used to assess tissue handling skill. ⋯ We developed a machine learning model to measure blood pixels in laparoscopic colorectal surgery images using RGB information. The blood pixel count per frame measured with this model significantly correlated with surgeons' tissue handling skills.

To discern the impact of diabetes mellitus (DM) on spinal cord injury (SCI) after open descending thoracic and thoracoabdominal aneurysm repair (DTAAAR). ⋯ DM is associated to increased OM and decreased survival, and it is an independent predictor of SCI after open DTAAAR. Strict perioperative glycemic control should be implemented, and exogenous ketones should be investigated as neuroprotective agents to reduce such adverse events.

This study aimed to characterize postpancreatectomy acute pancreatitis (PPAP) after pancreaticoduodenectomy (PD) in a high-volume center. ⋯ PPAP is a distinct complication after PD with distinctive clinical outcomes. A part of PPAP presents as an inflammatory process in the early postoperative period but sometimes could lead to necrotizing pancreatitis or other severe clinical scenarios, and another part of PPAP would lead to anastomotic failure that accounts for a great proportion of POPF occurrence.
