Background/Aims: We investigated the clinical practice patterns of Korean endoscopists for the endoscopic resection of colorectal polyps. Methods: From September to November 2021, an online survey was conducted regarding the preferred resection methods for colorectal polyps, and responses were compared with the international guidelines. Results: Among 246 respondents, those with <4 years, 4–9 years, and ≥10 years of experiencein colonoscopy practices accounted for 25.6%, 34.1%, and 40.2% of endoscopists, respectively. The most preferred resection methods for non-pedunculated lesions were cold forceps polypectomy for ≤3 mm lesions (81.7%), cold snare polypectomy for 4–5 mm (61.0%) and 6–9 mm (43.5%) lesions, hot endoscopic mucosal resection (EMR) for 10–19 mm lesions (72.0%), precut EMR for 20–25 mm lesions (22.0%), and endoscopic submucosal dissection (ESD) for ≥26 mm lesions (29.3%). Hot EMR was favored for pedunculated lesions with a head size <20 mm and stalk size <10 mm (75.6%) and for those with a head size ≥20 mm or stalk size ≥10 mm (58.5%). For suspected superficial and deep submucosal lesions measuring 10–19 mm and ≥20 mm, ESD (26.0% and 38.6%) and surgery (36.6% and 46.3%) were preferred, respectively. The adherence rate to the guidelines ranged from 11.2% to 96.9%, depending on the size, shape, and histology of the lesions. Conclusions Adherence to the guidelines for endoscopic resection techniques varied depend-ing on the characteristics of colorectal polyps. Thus, an individualized approach is required to increase adherence to the guidelines.

Purpose: Exercise is an effective non-pharmacological approach for alleviating treatment-related adverse effects and enhancing physical fitness in breast cancer survivors. A Kinect-based mixed reality device (KMR), with real-time feedback and user data collection, is an innovative exercise intervention for breast cancer survivors. This study aimed to investigate the effect of KMR exercise program on quality of life (QOL) and physical function in breast cancer survivors. Materials and Methods: Seventy-seven participants were randomly assigned to either the KMR exercise group or home stretching group with an 8-week intervention. Physical function (shoulder range of motion, body composition, aerobic capacity, and hand grip strength) was evaluated before and after the intervention period. Participants completed questionnaires such as the Disabilities of the Arm, Shoulder, and Hand (DASH), Functional Assessment of Cancer Therapy-Breast, and International Physical Activity Questionnaire (IPAQ) to assess upper extremity disabilities, QOL, and physical activity levels. Results: Significant group-by-time interaction was found for flexion of the operated arm (154.3±12.5 to 165.8±11.2), and the non-operated arm (158.2±13.8 to 166.5±12.2), abduction of the non-operated arm (154.8±31.6 to 161.1±28.1), and adduction of the operated arm (46.5±9.1 to 52.6±7.2). Significant improvements were also observed in DASH (46.8±9.1 to 40.8±9.3) and IPAQ (1,136.3±612.8 to 1,287±664.1). Conclusion The KMR exercise program effectively improved the physical function, alleviated edema, reduced upper extremity disability, and enhanced the QOL in breast cancer survivors. Coupled with significant group-by-time interactions for various outcomes, the results emphasize the potential benefits of incorporating the KMR exercise program to improve the QOL in breast cancer survivors.

Background: Sarcopenia is a muscle-wasting condition that affects older individuals. It can lead to changes in movement patterns, which can increase the risk of falls and other injuries. Methods: Older women participants aged ≥65 years who could walk independently were recruited and classified into two groups based on knee extension strength (KES). Participants with low KES scores were assigned to the possible sarcopenia group (PSG; n=7) and an 8-week exercise intervention was implemented. Healthy seniors with high KES scores were classified as the reference group (RG; n=4), and a 3-week exercise intervention was conducted. Kinematic movement data were recorded during the intervention period. All participants' exercise repetitions were used in the data analysis (number of data points=1,128). Results: The PSG showed significantly larger movement patterns in knee rotation during wide squats compared to the RG, attributed to weakened lower limb strength. The voting classifier, trained on the movement patterns from wide squats, determined that significant differences in overall movement patterns between the two groups persisted until the end of the exercise intervention. However, after the exercise intervention, significant improvements in lower limb strength in the PSG resulted in reduced knee rotation range of motion and max, thereby stabilizing movements and eliminating significant differences with the RG. Conclusion This study suggests that exercise interventions can modify the movement patterns in older individuals with possible sarcopenia. These findings provide fundamental data for developing an exercise management system that remotely tracks and monitors the movement patterns of older adults during exercise activities.
