抄録	Common bile duct (CBD) injury after blunt abdominal trauma is rare and difficult to diagnose. Delayed recognition leads to severe morbidity. A 70-year-old Japanese man was admitted after sustaining blunt abdominal trauma. Ultrasonography revealed intra-abdominal fluid, suggesting bleeding. Contrast-enhanced computed tomography revealed pancreatic head injury, intra-abdominal bleeding, and pseudoaneurysm of the anterior superior pancreatoduodenal artery (ASPDA). Bile duct injury was not evident. The application of transarterial embolization (TAE) controlled the bleeding. Canulation into the pancreatic or biliary duct was not possible during endoscopic retrograde cholangiopancreatography. An emergency laparotomy revealed severe pancreatic head and extrahepatic bile duct injuries. Pancreaticoduodenectomy/Child reconstruction was performed. Complete CBD transection was confirmed. The patient was ultimately discharged without complications. Early recognition, timely surgical management, and intensive care are essential for favorable outcomes in patients who have sustained abdominal trauma.

抄録	VEXAS (vacuoles, E1 enzyme, X-linked, autoinflammatory somatic) syndrome has a poor prognosis, with infections being a major cause of death. Raoultella ornithinolytica is an environmental bacterium found predominantly in soil and water. Although R. ornithinolytica can cause various infections, necrotizing fasciitis due to this bacterium has not been reported. We describe the case of an 84-year-old Japanese male with VEXAS syndrome who developed septic shock and necrotizing fasciitis while he was under immunosuppressive therapy. The pathogen was initially misidentified as R. planticola by mass spectrometry but later confirmed by whole-genome sequencing as extended spectrum β-lactamase (ESBL) produced by R. ornithinolytica. Although a life-saving leg amputation was required, the patient recovered with appropriate antibiotic therapy. R. ornithinolytica is thus able to cause severe skin infections in immunocompromised individuals.

A Mixed-Methods Study on Changes in Interprofessional Education Attitudes and Fundamental Competencies: A Pre–Post Analysis of Clinical Training in Dietetic Students

抄録	This study examined the effects of interprofessional education (IPE) on dietetics students during clinical training, focusing on changes in their attitudes toward IPE and their fundamental competencies. Eighty third-year female students (mean age, 21.0 years) at a Japanese women’s university participated. Self-administered surveys were conducted before and after clinical training to assess attitudes toward IPE using the Readiness for Interprofessional Learning Scale (RIPLS) and the Shakaijin Kisoryoku (SKL; Fundamental Competencies for Working Persons) scale. Quantitative data were analyzed using paired t-tests, chi-squared tests, and cluster analyses. Qualitative data from open-ended responses were analyzed thematically. RIPLS and SKL scores increased significantly, from 65.3 to 68.9, and from 28. 4 to 33. 2, respectively (p<0.001). All 12 SKL items showed significant improvement. In free responses, “initiative” (66 mentions), “communication” (10), and “execution” (8) were the most frequently cited as improved competencies. Cluster analysis identified three groups: increasing scores (n=25), high baseline (n=30), and minimal change (n=25). No significant correlation was found between changes in RIPLS and SKL scores (r=−0.108, p=0.355). IPE integrated into clinical training may enhance dietetics students’ attitudes toward interprofessional collaboration and contribute to the development of professional identity. Individualized, phased IPE implementation is recommended to accommodate differences in learner readiness.

Consistent Clinical Outcomes of Anteroinferior Minimally Invasive Plate Osteosynthesis for Midshaft Clavicle Fractures Across AO/OTA Fracture Types

抄録	Although the performance of minimally invasive plate osteosynthesis (MIPO) via the anteroinferior approach is increasingly adopted for midshaft clavicle fractures, the influence of fracture morphology on clinical outcomes under a standardized protocol is unclear. We retrospectively analyzed the cases of 54 patients who underwent anteroinferior MIPO for an acute midshaft clavicle fracture (AO/OTA types B1, B2, B3) performed by a single surgeon across three affiliated institutions (2009-2022). We evaluated the clinical outcomes, i.e., the surgical time, incision length, radiographic union, reduction accuracy, range of motion, pain (visual analog scale [VAS]), and complications and compared them among the three AO/OTA subtypes. The mean incision length (3.4 cm) and surgical time (71-79 min) were similar among the groups (both p>0.2). All fractures achieved radiographic union at a mean of 3.5 months. Postoperative alignment and clavicular length were maintained (length reduction −1.0±2.2 mm [B1], −0.5±2.0 mm [B2], −0.6±1.8 mm [B3]; p=0.825; angulation −0.8±3.4°, −1.1±3.1°, −0.3±3.3°; p=0.888). At 3 months, shoulder elevation and abduction were 169°-175° (p=0.079) and 164°-175° (p=0.324). Pain was minimal (100-mm VAS: ≤1 mm; p=0.782). One plate-fatigue failure occurred; no supraclavicular-nerve symptoms were recorded. Anteroinferior MIPO yielded consistent outcomes across AO/OTA types, with excellent union rates, functional recovery, and few complications, indicating that this technique is safe and reproducible for the surgical management of midshaft clavicle fractures.

Effects of Nonsurgical Periodontal Treatment on Bacterial and Clinical Parameters in Down Syndrome Patients Based on 16S rRNA Gene Amplicon Sequencing

抄録	Individuals with Down syndrome (DS) are more susceptible to periodontal disease; however, microbial changes following treatment remain insufficiently understood. This study evaluated the effects of nonsurgical periodontal therapy on clinical outcomes and oral microbiome dynamics in 6 patients with DS using 16S rRNA gene amplicon sequencing. Bacterial diversity, composition, network structure, and predicted functional pathways were analyzed using dental plaque samples. Bleeding on probing decreased significantly (p=0.047) after treatment, with a trend toward reduction in periodontal inflamed surface area (p=0.05). The abundance of Fusobacteria at the class level decreased significantly after treatment. The abundance of Mogibacterium timidum was higher in the pretreatment group than in the posttreatment group. M. timidum was positively correlated with Treponema denticola and associated with multiple bacterial taxa in the network during pretreatment. Predicted functional pathways related to aromatic compound degradation were more abundant in posttreatment samples than in pretreatment samples. An increase in the abundance of Fusobacterium and the positive correlation between T. denticola and M. timidum, together with their associations with other periodontal pathogens before treatment, may contribute to the development of periodontitis in individuals with DS. Nonsurgical periodontal therapy produces measurable clinical improvement and promotes microbial shifts in patients with DS.

Environmental Conservation Costs and Operational Efficiency: Evidence from Japanese Manufacturing Firms

抄録	This study investigates whether environmental conservation costs (ECC) support the operational effectiveness and financial stability of Japanese manufacturing firms. Using a balanced panel of 128 non-financial companies listed on the Tokyo Stock Exchange from 2010 to 2022, we manually collected firm-level ECC data based on the Ministry of the Environment, Japan's guidelines from sustainability reports and matched them with financial data from Compustat Global/S&P Capital IQ. Applying pooled ordinary least squares regression with firm-level clustered standard errors and winsorized variables, we examine two aspects of performance as measures of operating efficiency and profitability: asset turnover and profit margin. The results show that ECC is positively associated with asset turnover and profit margin, and that the effect is stronger in more profitable companies, substantiating the Resource-Based View that green practices generate competitiveness. These findings contribute to sustainability finance research by going beyond perceptual measures of environmental, social, and governance ratings, and measuring actual firm-level spending on environmental activities, thereby providing more nuanced insights into how environmental practices translate into actual financial performance. This study offers clear managerial and policy implications by showing that transparent environmental conservation costs improve disclosure quality and serve as a measure of improved efficiency and profitability.
