It has been absent from an accepted criteria for normalization and quality control of the thoracic surgery until now. The ideal assessing instrument which will be used to evaluate the technical skills and surgical procedures should present a few vital characterizations below: objectivity, speciality in the content, detailed structure, and quantifiability. Objective structured assessment of technical skills (OSATS) has developed as a reliable method of surgical skills measurement. This article focuses on the history of OSATS and its prospect in the thoracic surgery area by reviewing relevant literatures.
As a major disease that seriously endangers the health of Chinese residents, stroke has various triggering factors, among which infection is one of the initial factors. Previous studies have indicated a correlation of common oral infectious diseases such as periodontitis with the occurrence of stroke. However, there is a lack of effective integration of previous research on the induction of stroke by common oral infectious diseases. This article provides a comprehensive review of the relevant research on infectious diseases and stroke, with a particular focus on the progress related to periodontitis, gingivitis, dental caries, and pulpitis as triggers for stroke. It puts forward relevant recommendations for promoting oral health, so as to provide a theoretical basis for improving oral health literacy of Chinese residents and reducing the incidence of stroke and other major diseases.
Objective To study the correlation of preoperative hemoglobin amount with venous thromboembolism (VTE) after surgical treatment of bronchiectasis and the clinical significance. Methods A retrospective study was performed on patients with bronchiectasis who underwent surgical treatment in our center from June 2017 to November 2021. The differences in blood parameters between the VTE patients and non-VTE patients were compared. The relationship between preoperative hemoglobin and VTE was confirmed by quartile grouping and receiver operating characteristic (ROC) curve. Results A total of 122 patients were enrolled, including 50 males and 72 females, with a mean age of 52.52±12.29 years. The overall incidence of VTE after bronchiectasis was 9.02% (11/122). Preoperative hemoglobin amount (OR=0.923, 95%CI 0.870-0.980, P=0.008) and D-dimer amount (OR=1.734, 95%CI 1.087-2.766, P=0.021) were independent influencing factors for VTE after bronchiectasis. The incidence of VTE after bronchiectasis decreased gradually with the increase of preoperative hemoglobin amount. The area under the ROC curve (AUC) of postoperative D-dimer alone was 0.757, whereas the AUC of postoperative D-dimer combined with preoperative hemoglobin amount was 0.878. Conclusion Low preoperative hemoglobin is an independent risk factor for postoperative VTE. Postoperative D-dimer combined with preoperative hemoglobin amount has a better predictive performance compared with postoperative D-dimer alone for postoperative VTE.
