What digital health technology types are used in mental health prevention and intervention? Review of systematic reviews for systematization of technologies.

Digital health technology has been widely applied to mental health interventions worldwide. Using digital phenotyping to identify an individual's mental health status has become particularly important. However, many technologies other than digital phenotyping are expected to become more prevalent in the future. The systematization of these technologies is necessary to accurately identify trends in mental health interventions. However, no consensus on the technical classification of digital health technologies for mental health interventions has emerged. Thus, we conducted a review of systematic review articles on the application of digital health technologies in mental health while attempting to systematize the technology using the Delphi method. To identify technologies used in digital phenotyping and other digital technologies, we included 4 systematic review articles that met the inclusion criteria, and an additional 8 review articles, using a snowballing approach, were incorporated into the comprehensive review. Based on the review results, experts from various disciplines participated in the Delphi process and agreed on the following 11 technical categories for mental health interventions: heart rate estimation, exercise or physical activity, sleep estimation, contactless heart rate/pulse wave estimation, voice and emotion analysis, self-care/cognitive behavioral therapy/mindfulness, dietary management, psychological safety, communication robots, avatar/metaverse devices, and brain wave devices. The categories we defined intentionally included technologies that are expected to become widely used in the future. Therefore, we believe these 11 categories are socially implementable and useful for mental health interventions.

Promoting endoscopists' health through cutting-edge motion analysis technology: Accuracy and precision of ergonomic motion tracking system for endoscopy suite (EMTES).

OBJECTIVES: Endoscopists often suffer from musculoskeletal disorders due to posture-specific workloads imposed by precise maneuvering or long procedural duration. An ergonomic motion tracking system for endoscopy suite (EMTES) was developed using Azure Kinect sensors to evaluate the occlusion, accuracy, and precision, focusing mainly on upper and lower limb movements. METHODS: Three healthy male participants pointed the prescribed points for 5 s on the designated work envelopes and their coordinates were measured. The mean occlusion rate (%) of the 32 motion tracking landmarks, standard deviation (SD) of distance and orientation, and partial regression coefficient (ß) and R2 model fit for accuracy were calculated using the time series of coordinates data of the upper/lower limb movements. RESULTS: The mean occlusion rate was 5.2 ± 10.6% and 1.6 ± 1.4% for upper and lower limb movements, respectively. Of the 32 landmarks, 28 (87.5%) had occlusion rates of 10% or less. The mean SDs of 4.2 mm for distance and 1.2° for orientation were found. Most of the R2 values were over 0.9. In the case of right upper/lower limb measurement for orientation, ß coefficients ranged from 0.82 to 1.36. CONCLUSION: EMTES is reliable in calculating occlusion, precision, and accuracy for practical motion-tracking measurements in endoscopists.

Effects of endoscopy-related procedure time on musculoskeletal disorders in Japanese endoscopists: a cross-sectional study.

Background and study aims There has been little evidence assessing the prevalence of musculoskeletal disorders (MSDs) among endoscopists performing recent diagnostic and therapeutic endoscopic procedures requiring prolonged procedural times. We evaluated the prevalence and identified the risk factors for developing MSDs, focusing on procedural time. Methods An electronic survey of endoscopists (n = 213) employed at the Nagoya University Hospital and its affiliated hospitals was developed by a multidisciplinary group.  Results Of the 110 endoscopists (51.6 %) who responded to the survey, eighty-seven endoscopists (79.1 %) had experienced endoscopy-related MSDs during the previous 1 year, and 49 endoscopists (44.5 %) had experienced these MSDs during the previous week. Nineteen endoscopists (17.3 %) reported absence from work due to severe MSDs. The most frequent sites of MSDs were neck, low back, and shoulders. Logistic regression analyses showed that longer upper endoscopic submucosal dissection ESD, (odds ratio: 5.7; 95 %CI: 1.3-25.0), lower ESD (odds ratio 4.9; 95 %CI: 1.1-22.0), and lower gastrointestinal treatment (odds ratio: 5.6; 95 %CI: 2.3-13.3) were significantly associated with the development of MSDs in the low back area. Moreover, longer lower ESD (odds ratio: 5.0; 95 % CI: 1.2-20.2) was a risk factor for symptoms in the left shoulder. Conclusion This study suggests a correlation between the volume of therapeutic endoscopic procedures including ESD and the risk of MSDs mainly low back area and left shoulder. Managing monthly total endoscopic time, in light of organizational ergonomics, could contribute to minimizing such risks of endoscopy-related MSDs.

Magnetic anchor-guided endoscopic submucosal dissection for colorectal tumors (with video).

BACKGROUND: The feasibility of magnetic anchor-guided endoscopic submucosal dissection (MAG-ESD) using a neodymium magnet for colorectal tumors has not been evaluated. The aim of this study was to clarify the feasibility of MAG-ESD for colorectal tumors. METHODS: This prospective trial was conducted at Yamashita Hospital. MAG-ESD was performed for 49 colorectal tumors. The magnetic anchor comprised an internal magnet attached to an endoclip with 3-0 silk. Both external and internal magnets were made using neodymium magnets. The feasibility of traction achieved using MAG-ESD, en bloc resection rate, complete en bloc resection rate, time required for preparation and attachment of the magnetic anchor, procedure time, rate of retrieval of magnetic anchors, and adverse events were evaluated. RESULTS: MAG-ESDs were successfully performed for 48 colorectal tumors except for a rectal case in which the internal magnet stuck to the endoscope. En bloc resections and complete en bloc resections were achieved in all cases. Attaching the magnetic anchor required a median of 8 min (range 3-37 min). Median procedure time was 76 min (range 28-283 min) and the magnetic anchors were retrieved in all cases without adverse events. CONCLUSION: MAG-ESD is feasible and safe in the colon and may facilitate the treatment of all difficult lesions. (UMIN000024100).
