        Medical students’ self-assessed efficacy and satisfaction with training on endotracheal intubation and central venous catheterization with smart glasses in Taiwan: a non-equivalent control-group pre- and post-test study

        Yu-Fan Lin,Chien-Ying Wang,Yen-Hsun Huang,Sheng-Min Lin,Ying-Ying Yang 한국보건의료인국가시험원 2022 보건의료교육평가 Vol.19 No.-

        Purpose Endotracheal intubation and central venous catheterization are essential procedures in clinical practice. Simulation-based technology such as smart glasses has been used to facilitate medical students’ training on these procedures. We investigated medical students’ self-assessed efficacy and satisfaction regarding the practice and training of these procedures with smart glasses in Taiwan. Methods This observational study enrolled 145 medical students in the 5th and 6th years participating in clerkships at Taipei Veterans General Hospital between October 2020 and December 2021. Students were divided into the smart glasses or the control group and received training at a workshop. The primary outcomes included students’ pre- and post-intervention scores for self-assessed efficacy and satisfaction with the training tool, instructor’s teaching, and the workshop. Results The pre-intervention scores for self-assessed efficacy of 5th- and 6th-year medical students in endotracheal intubation and central venous catheterization procedures showed no significant difference. The post-intervention score of self-assessed efficacy in the smart glasses group was better than that of the control group. Moreover, 6th-year medical students in the smart glasses group showed higher satisfaction with the training tool, instructor’s teaching, and workshop than those in the control group. Conclusion Smart glasses served as a suitable simulation tool for endotracheal intubation and central venous catheterization procedures training in medical students. Medical students practicing with smart glasses showed improved self-assessed efficacy and higher satisfaction with training, especially for procedural steps in a space-limited field. Simulation training on procedural skills with smart glasses in 5th-year medical students may be adjusted to improve their satisfaction.

        Red Bean Extract Inhibits Lipopolysaccharide-Induced Inflammation and H2O2-Induced Oxidative Stress in RAW 264.7 Macrophages

        Wen-Wan Chao,Yun-Chin Chung,I-Ping Shih,Hsun-Yen Wang,Su-Tze Chou,Cheng-Kuang Hsu 한국식품영양과학회 2015 Journal of medicinal food Vol.18 No.7

        Red bean (Phaseolus radiatus L. var. Aurea) is a leguminous seed and mainly used as one of the popular ingredients in oriental desserts. The objective of this study was to evaluate the anti-inflammatory activity of 50 g/kg ethanolic extract of red bean (RBE) by measuring lipopolysaccharide (LPS)-induced expressions of nitric oxide (NO), inducible nitric oxide synthase (iNOS), cyclooxygenase 2 (COX-2), tumor necrosis factor-α (TNF-α), and interleukin-6 (IL-6) in RAW 264.7 macrophages. On the other hand, the antioxidant activity of RBE was determined by thiobarbituric acid reactive substances method and comet assay using H2O2-induced macrophages. The results showed that RBE at the concentrations of 50–200 μg/mL can significantly suppress the inflammatory responses in LPS-stimulated macrophages through the reduction of cellular NO and downregulation of the gene expressions of iNOS, COX-2, TNF-α, and IL-6 in a dose-dependent manner. Furthermore, RBE can diminish H2O2-induced oxidative damage in RAW 264.7 macrophage. Phenolic compounds and cyanidin-3-Oglucoside from BRE may have efficacy as overall in vitro anti-inflammatory and antioxidant agents. Red bean exerts an antiinflammatory response and has potential as a health-promoting ingredient.
