Certain physiology concepts can be difficult for students to understand, and new strategies need to be implemented to teach these concepts. Cell signaling is a core concept in physiology and is presented to undergraduate students starting with their first-year Principles of Biology course. Flipped teaching (FT) combined with dramatizations were used to teach steroid hormone and protein hormone cell signaling in an Animal Physiology course. Student knowledge level improved, as demonstrated by posttest scores compared to pretest scores. Their confidence level in the material improved after the dramatization activities were completed. In conclusion, the combination of FT with dramatizations enhances student learning and confidence level.The core problem of Chinese resident doctor training is that medical educators present content in an attractive teaching mode to make students more motivated to learn and improve their clinical thinking ability, humanistic care, and practical ability. The traditional classroom mode of teaching cannot meet the needs of modern medical education. The purpose of this study is to explore the benefits and challenges of the flipped classroom (FC) combined with case- and team-based learning (FC-CTBL) for residency training. In this study, 60 junior surgical residents of Xiangya Medical College were enrolled. "Diabetic foot" was selected as the content of this study. Residents were divided into an FC-CTBL group and an FC group. FC-CTBL and FC were compared on the basis of residents' feedback questionnaires, residents' learning burden, test scores from a pre-quiz, and objective structured clinical examinations (OSCE). Residents were more satisfied with the FC-CTBL model compared with FC. In the FC-CTBL group, more participants said that the course improved their teamwork skills, analytical skills and their confidence in tackling unfamiliar problems. Residents in the FC-CTBL group also spent significantly less time preparing for class and performed better in the OSCE than those in the FC group. FC-CTBL stimulates residents' learning motivation, decreases their workload, improves their performance in the OSCE and may help to enhance clinical thinking and teamwork skills. The FC-CTBL approach is a good option for residency training.Online supplemental material is available for this article.Background To reduce adverse effects of whole-gland therapy, participants with localized clinically significant prostate cancer can undergo MRI-guided focal therapy. Purpose To explore safety and early oncologic and functional outcomes of targeted focal high-intensity focused ultrasound performed under MRI-guided focused ultrasound for intermediate-risk clinically significant prostate cancer. Materials and Methods In this prospective phase II trial, between February 2016 and July 2019, men with unifocal clinically significant prostate cancer visible at MRI were treated with transrectal MRI-guided focused ultrasound. The primary end point was the 5-month biopsy (last recorded in December 2019) with continuation to the 24-month follow-up projected to December 2021. Real-time ablation monitoring was performed with MR thermography. Nonperfused volume was measured at treatment completion. Periprocedural complications were recorded. Follow-up included International Prostate Symptom Score (IPSS) and International Inciated with a decline in IIEF-15 scores at 6 weeks (adjusted P less then .01) and at 5 months (adjusted P = .07). ASP2215 price Conclusion Targeted focal therapy of intermediate-risk prostate cancer performed with MRI-guided focused ultrasound ablation was safe and had encouraging early oncologic and functional outcomes. © RSNA, 2021 Online supplemental material is available for this article See also the editorial by Tempany-Afdhal in this issue.Background The solid portion size of lung cancer lesions manifesting as subsolid lesions is key in their management, but the automatic measurement of such lesions by means of a deep learning (DL) algorithm needs evaluation. Purpose To evaluate the performance of a commercially available DL algorithm for automatic measurement of the solid portion of surgically proven lung adenocarcinomas manifesting as subsolid lesions. Materials and Methods Surgically proven lung adenocarcinomas manifesting as subsolid lesions on CT images between January 2018 and December 2018 were retrospectively included. Five radiologists independently measured the maximal axial diameter of the solid portion of lesions. The DL algorithm automatically segmented and measured the maximal axial diameter of the solid portion. Reader measurements, software measurements, and invasive component size at pathologic examination were compared by using intraclass correlation coefficient (ICC) and Bland-Altman plots. Results A total of 448 patients (melearning algorithm were comparable with manual measurements and showed good agreement with invasive component size at pathologic evaluation. © RSNA, 2021 Online supplemental material is available for this article.Background In multiple sclerosis (MS), gray matter (GM) atrophy exhibits a specific pattern, which correlates strongly with clinical disability. However, the mechanism of regional specificity in GM atrophy remains largely unknown. Recently, the network degeneration hypothesis (NDH) was quantitatively defined (using coordinate-based meta-analysis) as the atrophy-based functional network (AFN) model, which posits that localized GM atrophy in MS is mediated by functional networks. Purpose To test the NDH in MS in a data-driven manner using the AFN model to direct analyses in an independent test sample. Materials and Methods Model fit testing was conducted with structural equation modeling, which is based on the computation of semipartial correlations. Model verification was performed in coordinate-based data of healthy control participants from the BrainMap database (https//www.brainmap.org). Model validation was conducted in prospectively acquired resting-state functional MRI in participants with relapsing-remi resting-state functional MRI scans, reduced functional network integrity in participants with MS had a strong positive correlation with clinical disability. © RSNA, 2021 Online supplemental material is available for this article.
