OBJECTIVES: This study aimed to develop an effective and efficient obesity treatment and management service platform for obese children/teenagers. METHODS: The integrated smart platform was planned and established through cooperation with service providers such as hospitals and public health centers, obese children/teenagers who constitute the service's user base, and IT development and policy institutions and companies focusing on child-teen obesity management and treatment. RESULTS: Based on guidelines on intervention strategies to manage child-teen obesity, we developed two patient/parent mobile applications, one web-monitoring service for medical staff, one mobile application for food-craving endurance, and one mobile application for medical examinations. CONCLUSIONS: The establishment of the integrated service platform was successfully completed; however, this study was restrictively to the hospital where the pilot program took place. The effectiveness of the proposed platform will be verified in the future in tests involving other organizations.

BACKGROUND: To determine whether olecranon fractures have osteoporotic features such as age-dependent, low bone attenuation and low-energy trauma as a cause of injury. METHODS: Elbow computed tomography (CT) and medical record review were performed in 114 patients (53 males and 61 females) with acute olecranon fractures. The mean age was 57 years. Bone attenuation was measured on the central part of the olecranon on sagittal CT images avoiding the fracture, and on the distal humerus (distal metaphysis and medial and lateral condyles) on coronal CT images. We compared bone attenuation and causes of injury (high or low energy trauma) between younger (<50 years) and older (≥50 years) patients in each gender. Multiple regression analysis was performed to determine the effect of age and gender on bone attenuation. RESULTS: Mean bone attenuation in older male and female patients was significantly lower than in younger patients, except at the medial condyle in men. The proportion of low-energy trauma in older male patients was significantly higher than in younger male patients. In female patients, low-energy trauma was predominant in both younger and older patients. Age and female gender had significantly negative effects on bone attenuation. CONCLUSIONS: This study demonstrated that olecranon fractures have osteoporotic features, including age-dependent low bone attenuation and low-energy trauma as the predominant cause of injury. Our results suggest that osteoporosis evaluation should be considered for patients aged 50 years or more with olecranon fractures.

PURPOSE: To compare the clinical 3 months postoperative results of three different 1-piece aspheric intraocular lenses (IOLs): AcrySof IQ SN60WF (Alcon Laboratories, INC, Fort Worth, TX), TECNIS 1-piece ZCB00 (AMO Inc., Santa Ana, CA) and the newly developed enVista MX60 (Bausch & Lomb, Rochester, NY). METHODS: In a total of 62 eyes, 1 of the 3 1-piece aspheric IOLs, AcrySof IQ SN60WF, TECNIS 1-piece ZCB00 or enVista MX60 was implanted after cataract extraction. Best corrected visual acuity (BCVA), uncorrected visual acuity (UCVA), and spherical equivalent were assessed 3 months postoperatively. Total spherical aberration, high order aberration, and modulation transfer function were analyzed. RESULTS: There were no significant differences of UCVA, BCVA, the accuracy of postoperative refractive power, and modulation transfer function among the 3 IOLs. Higher order aberrations of the entire eye and internal optics showed almost no significant differences. CONCLUSIONS: The newly developed IOL, enVista MX60, showed equivalent clinical outcomes as both AcrySof IQ SN60WF and TECNIS 1-piece ZCB00.
