PURPOSE: To compare the accuracy and clinical usefulness of various devices by measuring axial length, keratometry, and white-to-white. METHODS: In 64 eyes of 56 cataract patients, axial length was measured using Galilei™, Lenstar®, and A-scans, and keratometry was measured using Galilei™, Lenstar®, and ARK. In 86 eyes of 74 cataract patients, white-to-white was measured using Galilei™ and Lenstar®. RESULTS: The average axial length measurements using Galilei™, Lenstar®, and A-scans were significantly correlated (p < 0.001), but without a statistically significant difference (p = 0.611). The 95% agreement range was the smallest at 0.22 mm for the Lenstar® and A-scans. The average mean K using Galilei™, Lenstar®, and ARK were significantly correlated (p < 0.001), but without a statistically significant difference (p = 0.657). The 95% agreement range was relatively small at 1.83 D for Lenstar® and ARK. The average white-to-white using Galilei™ and Lenstar® were significantly correlated (p < 0.001), with a statistically significant difference (p = 0.011). The 95% agreement range was 2.20 mm. CONCLUSIONS: Axial length, keratometry, and white-to-white measured by different devices were highly correlated and were not statistically different; however, agreement was low between measurements. It is therefore important to consider these findings when using them equally.

PURPOSE: To report a case of irregular astigmatism caused by a free flap during laser-assisted in situ keratomileusis (LASIK) surgery that was treated with a flap rotation based on postoperative topography. CASE SUMMARY: A 21-year-old female underwent LASIK, which was complicated by a free cap on her right eye. Because the gentian violet markings were no longer present, the exact orientation of the cap was unknown. At 3 months after surgery, the astigmatism of the right eye was −3.00 diopters (D) with an uncorrected visual acuity (UCVA) of 0.4, and the astigmatism of the left eye was −0.75 D with an UCVA of 1.0. The corneal topography was analyzed in order to return to the existing position. Free cap repositioning was performed and irregular astigmatism was corrected to improve the UCVA to 1.0. CONCLUSIONS: If the preoperative markings cannot be identified on a free flap during LASIK, secondary postoperative corneal topographic analysis can be performed to restore the corneal free flap to its original position to minimize astigmatism with good visual outcomes.

OBJECTIVES: This study developed an information and communication technology (ICT)-based comprehensive health and social-needs assessment (CHSNA) system based on the International Classification of Functioning, Disability, and Health (ICF) with the aim of enhancing person-centered community care for community residents and supporting healthcare professionals and social workers who provide healthcare and social services in the community. METHODS: Items related to a CHSNA tool were developed and mapped with ICF codes. Experts validated the CHSNA system design and process using the Delphi method, and a pilot test of the initial version of the system was conducted. RESULTS: The following three steps of CHSNA were embedded in the system, which had a user-friendly screen and images: basic health assessment, life and activity assessment, and in-depth health assessment. The assessment results for the community residents were presented with visualized health profiles, including images, graphs, and an ICF model. CONCLUSIONS: The developed CHSNA system can be used by healthcare professionals, social workers, and community residents to evaluate the reasoning underlying health and social needs, to facilitate the identification of more appropriate healthcare plans, and to guide community residents to receive the best healthcare services. A CHSNA system can improve the implementation of standardized terminology utilizing the ICF and the accuracy of needs assessments of community residents.

Coronavirus disease 2019 (COVID-19) is a global pandemic that had affected more than eight million people worldwide by June 2020. Given the importance of the presence of diabetes mellitus (DM) for host immunity, we retrospectively evaluated the clinical characteristics and outcomes of moderate-to-severe COVID-19 in patients with diabetes.

Objective·To analyze the anatomical and macroscopic characteristics of the pterygopalatine suture(PPS)in Chinese population using cone-beam computed tomography(CBCT)technology,and to preliminarily investigate its developmental pattern and its association with the correction of maxillary underdevelopment.Methods·A total of 134 CBCT images,taken from July to August 2023 at Shanghai Ninth People's Hospital,Shanghai Jiao Tong University School of Medicine,were categorized into six age groups.The PPS landmarks were utilized to determine the overall transverse position(XPPS),sagittal position(YPPS),insertion angle(IAP),insertion width of the pyramidal process(IWP),and insertion depth of the pyramidal process(IDP).The pterygomaxillary junction was identified through multiplanar observations.Regression analysis was performed to assess the correlation of these parameters with age and gender,and pairwise comparisons were made to determine the stable age range for parameter changes.Paired t-tests and paired chi-squared tests were conducted to analyze the bilateral parameter differences.Results·Results showed that YPPS and IDP did not exhibit significant correlation with age,whereas XPPS,IAP,IWP,and the incidence of pterygomaxillary fusion were significantly positively correlated with age(P<0.01).Gender differences were only significant for XPPS,with males demonstrating greater values than females(P<0.01).Analysis of age-related trends indicated significant differences in XPPS between group 1(6 years≤age<9 years)and group 2(9 years≤age<12 years)(female:P=0.006,male:P=0.004);significant differences in IAP were observed between group 2 and group 3(12 years≤age<15 years)(P=0.042),with 98.5%of samples having an IAP greater than 45 degrees;IWP differences were significant between group 1 and group 3(P=0.016),and the pterygomaxillary fusion incidence was significantly different among group 1,2,and 3(group 1 vs.2:P<0.001,group 2 vs 3:P=0.037,group 1 vs 3:P<0.001),with an incidence rate exceeding 90%in adults.No significant bilateral differences were found for all parameters.Conclusion·No significant changes were observed in YPPS and IDP after the age of 6,indicating a trend towards fusion of the maxilla with the pterygoid process.The overall transverse position of the PPS tends to stabilize around 12 years of age,while the IAP and IWP continue to increase and reach stability around 15 years of age,with a sagittal insertion orientation of the pyramidal process into the pterygoid notch.
