| Abstract | A 79-year-old woman with severe fever with thrombocytopenia syndrome (SFTS) developed progressive atrioventricular (AV) conduction disturbances during hospitalization. On hospital day 6, first-degree AV block progressed to transient complete AV block, causing syncope and a 15-sec asystolic pause. Echocardiography showed preserved ventricular function, and cardiac magnetic resonance imaging did not support clinically overt myocarditis. A temporary transvenous pacemaker was inserted, and AV conduction recovered spontaneously; pacing was discontinued by day 9 without permanent pacemaker implantation. This case suggests that SFTS can cause reversible high-degree AV block and may warrant continuous twelve-lead electrocardiography (ECG) monitoring and timely temporary pacing. |

| Abstract | A 67-year-old man presented with sudden-onset abdominal pain and hemorrhagic shock. Contrast-enhanced CT revealed a large hematoma in hepatic segments VI-VII with capsular rupture and hemoperitoneum. CT angiography demonstrated a saccular pseudoaneurysm in a posterior segmental branch of the right hepatic artery and a beaded appearance with irregular dilatation and segmental narrowing of the right hepatic artery branches, without inflammatory or atherosclerotic findings, supporting a diagnosis of segmental arterial mediolysis (SAM). Emergency angiography followed by coil embolization achieved hemostasis. Follow-up CT at 5 months showed complete exclusion of the aneurysmal lesions, with no evidence of recurrence or new vascular lesions. Coil embolization may be an effective, minimally invasive option for ruptured intrahepatic SAM lesions. |

| Abstract | This study evaluated the feasibility of predicting pathogenic BRCA1/2 variants in ovarian cancer using radiogenomic analysis of contrast-enhanced MRI. Twenty six patients were analyzed, including 14 with pathogenic BRCA1/2 variants and 12 without. Contrast enhanced MRI was used to generate two dimensional (2D) and three dimensional (3D) tumor segmentations. Radiomic features extracted with PyRadiomics were reduced using least absolute shrinkage and selection operator (LASSO) regression, yielding two selected features. Linear discriminant analysis (LDA) models were trained on 18 patients and tested on 8, with performance assessed using sensitivity, specificity, accuracy, and the area under the receiver operating characteristic (ROC) curve. The DeLong test compared AUCs between segmentation methods. Automated machine learning (AutoML) was performed with a training set of 20 patients and a test set of 6, with multiple performance metrics calculated. LDA achieved approximately 60% accuracy in both 2D and 3D test datasets. AUCs were 0.80 (3D) and 0.77 (2D), with no significant difference (p=0.85). AutoML identified CatBoost_BAG_L2_FULL as the optimal model, achieving accuracy above 80%. MRI-based radiogenomic analysis demonstrated moderate classification performance for identifying pathogenic BRCA1/2 variants in ovarian cancer. These preliminary findings suggest a potential role for noninvasive prediction, warranting further validation in larger cohorts. |

| Abstract | This study examined the dynamics of serum amyloid A (SAA) levels in the blood, brain, and liver over time using a mouse model of focal cerebral ischemia induced by occlusion of the middle cerebral artery (MCA) for 4 h followed by reperfusion. Blood SAA concentrations increased transiently after cerebral infarction, coinciding with changes in brain and liver SAA gene expression and protein levels. SAA concentrations in the brain, liver, and blood increased at similar time points after cerebral infarction, suggesting that SAA may serve as an important indicator of the associated pathological condition. |

| Abstract | This study evaluated the prognostic significance of the C-reactive protein–albumin–lymphocyte (CALLY) index and systemic immune-inflammation (SII) index in predicting postoperative outcomes in patients with esophageal squamous cell carcinoma (ESCC). A retrospective analysis was performed on clinical data from 102 patients with ESCC who underwent surgical resection at Western Theater General Hospital of China between January 2020 and July 2023. The associations between preoperative CALLY and SII indices and relapse-free survival (RFS) and overall survival (OS) were examined. Survival curves were generated using the Kaplan–Meier method, and prognostic factors were identified using Cox proportional hazards regression analysis. Patients with a high CALLY index had significantly longer RFS (HR=0.30, 95% CI: 0.13-0.71), and those with a low SII index also had significantly longer RFS (HR=2.23, 95% CI: 1.12-4.41). Similarly, patients with a high CALLY index had significantly longer OS (HR=0.27, 95% CI: 0.13-0.55), and those with a low SII index had significantly longer OS (HR=2.27, 95% CI: 1.09-4.71). When patients were stratified into four groups, the low-CALLY–high-SII group showed significantly shorter RFS than the high-CALLY–low-SII group (HR=0.26, 95% CI: 0.11-0.61; p=0.013), and OS was also significantly worse in the low-CALLY–high-SII group (HR=0.22, 95% CI: 0.09-0.54; p=0.016). Univariate Cox regression analysis identified both CALLY and SII as significant prognostic factors. In multivariate analysis, the CALLY index and N stage were independently associated with RFS, whereas only tumor size remained independently associated with OS. The combined assessment of preoperative CALLY and SII indices may be useful for prognostic stratification in patients with ESCC undergoing upfront surgical resection. It may help identify high-risk patient subgroups with distinct survival outcomes, thereby providing a potential rationale for stratifying postoperative surveillance and tailoring individualized adjuvant strategies, although validation in larger prospective cohorts is warranted. |

| Abstract | 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. |

| Abstract | 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. |

| Abstract | 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. |
