Safety and efficacy results of percutaneous renal stent implantation in patients with acute coronary syndrome with ectatic and aneurysmatic coronary arteries.
For the treatment of stenotic lesions developing in dilated coronary arteries, it is difficult to find an appropriately sized coronary stent given that the vessel diameter is too large. This poses a greater problem, especially in patients who require urgent intervention, such as acute coronary syndrome. ⋯ This study has been registered on ClinicalTrials.gov (NCT05410678).

Machine learning-based risk prediction of hypoxemia for outpatients undergoing sedation colonoscopy: a practical clinical tool.
Hypoxemia as a common complication in colonoscopy under sedation and may result in serious consequences. Unfortunately, a hypoxemia prediction model for outpatient colonoscopy has not been developed. Consequently, the objective of our study was to develop a practical and accurate model to predict the risk of hypoxemia in outpatient colonoscopy under sedation. ⋯ Our study selected the XGBoost as the first model especially for colonoscopy, with over 95% accuracy and excellent specificity. The XGBoost includes four variables that can be quickly obtained. Moreover, an online prediction practical tool has been provided, which helps screen high-risk outpatients with hypoxemia swiftly and conveniently.

Validation of the 35-mm rule in traumatic pneumothorax in an Asian population.
Thoracic injury crucially threatens human health. Recent studies have suggested using computed tomography (CT) to observe traumatic pneumothorax (PTX). However, cross-ethnic validation is required to overcome potential barriers for the global application of this method. This study aimed to validate the 35-mm rule in traumatic PTX in a Korean population. ⋯ Most patients with traumatic PTX of ≤35 mm on CT had undergone successful 4-h observation without thoracostomy. Additionally, PTX of >35 mm was an independent risk factor for observation failure. Considering the lower optimal cutoff value and high failure rates observed in this study, the current guidelines need modifications.
