抄録	The “CR Alignment” function was recently introduced in ZedHip®, the hip joint module of ZedView®, to evaluate pelvic tilt in non-supine positions via two-dimensional (2D)‒3D matching using radiographs. However, its ccuracy has not been validated. This study therefore evaluated the accuracy of pelvic tilt measurements using the CR Alignment function in dry pelvic bone specimens. Two cadaveric pelvic bone models were placed in nine orientations (anterior/posterior tilt and left/right rotation). Both radiographic and CT images were acquired in each position. In Study 1, pelvic tilt measured directly from CT images was defined as the “true value.” Three observers used the CR Alignment function to calculate pelvic tilt on radiographs, and measurement errors were determined relative to the true values. In Study 2, measurement errors were compared between matched (same position) and mismatched (different position) imaging. In Study 1, the mean measurement error was 1.28±0.64°. Intra- and interobserver intraclass correlation coefficients were 0.996-0.998 and 0.997, respectively. In Study 2, the mean errors were 1.20±0.88° (matched) and 1.32±1.03° (mismatched). This software exhibited high accuracy and reproducibility in 2D‒3D matching of pelvic tilt, with lower variability under matched acquisition, demonstrating its utility for pre- and postoperative assessment in joint arthroplasty.

Diabetes Mellitus as a Risk Factor for Severe COVID-19 and Pneumonia: A Comparison Between the Pre-Omicron and Omicron-Dominant Periods in Okayama City, Japan

抄録	Diabetes mellitus is a well-established risk factor for severe COVID-19; however, few studies have examined this association during the Omicron-dominant period. We conducted a population-based study using surveillance data from the Okayama City Public Health Center in Japan to compare the risk of severe COVID-19 and pneumonia among patients with diabetes mellitus between the pre-Omicron (March 2020–December 2021) and Omicron-dominant (January–September 2022) periods. Among 98,905 COVID-19 patients aged 10 years or older, we calculated adjusted odds ratios (aORs) controlling for age, sex, smoking status, comorbidities, obesity, and the number of COVID-19 vaccine doses received. In the pre-Omicron period, diabetes mellitus was significantly associated with severe COVID-19 (aOR: 1.36; 95% CI: 1.03-1.78), and this association persisted in the Omicron-dominant period (aOR: 1.54; 95% CI: 1.10-2.17). Similar findings were observed for pneumonia. The association was more pronounced among patients aged 40-69 years than among those aged 70 years or older. These findings suggest that diabetes mellitus remains an important risk factor for severe COVID-19 even during the Omicron-dominant period, highlighting the need for continued clinical vigilance and early intervention in patients with diabetes mellitus.

Artificial Intelligence-Assisted Peroral Cholangioscopy for the Diagnosis and Management of Biliary Strictures: Current Evidence and Future Directions

JaLCDOI	10.18926/AMO/71336

著者	Sato, Ryosuke\| Matsumoto, Kazuyuki\| Otsuka, Motoyuki\|
抄録	Peroral cholangioscopy (POCS) enables direct intraductal visualization and targeted biopsies for indeterminate biliary strictures. However, its diagnostic performance remains operator-dependent and is limited by sampling error. As artificial intelligence (AI) has rapidly advanced in gastrointestinal endoscopy, AI-assisted cholangioscopy has progressed from proof-of-concept image classification to multicenter validation, feature detection, and real-time application. Recent studies using digital single-operator cholangioscopy have reported diagnostic accuracy comparable to that of experts in differentiating malignant from benign strictures, and feature-based approaches can automatically detect tumor vessels and other key visual characteristics. Beyond classification, generative models may enhance mucosal and margin visualization through virtual chromoendoscopy, potentially improving lesion-margin assessment. Furthermore, new models compatible with multiple systems are emerging to address device heterogeneity, which is a key barrier to routine practice. This review summarizes the current evidence on AI-assisted POCS, discusses practical considerations for clinical translation, and highlights future directions, including real-time integration and multimodal decision support.
