Background: Identifying dysmorphic red blood cells (RBCs) is critical for diagnosing glomerular diseases, as distinguishing glomerular from non-glomerular hematuria may reduce reliance on invasive diagnostics such as kidney biopsy. We aimed to enhance urinary RBC morphological classification by employing machine learning (ML) to analyze UF-5000 scattergram data. Methods: RBCs in urine samples (N = 185) were classified as dysmorphic or isomorphic based on microscopic findings. UF-5000 scattergrams were quantified to generate 20 statistical features and used to train a ML model in DataRobot (v9.1) with an automated pipeline, five-fold cross-validation, and LogLoss-based selection. Performance was evaluated in an independent cohort (N = 1,093). Accuracy was defined as concordance with microscopy findings. Areas under ROC curves (AUROCs) and diagnostic metrics are reported with 95% confidence intervals (CIs). Results: Among conventional UF-5000 parameters, the small RBC/total RBC ratio was the strongest predictor (AUROC 0.97, 95% CI 0.94–0.99). Scattergram-derived features indicated that RBC size-related parameters were crucial for identifying dysmorphic RBCs. The ML model alone demonstrated superior accuracy over UF-5000 RBC-Info alone (concordance 95.2% vs. 92.1%; AUROC 0.95 [0.94–0.97] vs. 0.92 [0.91–0.94]). Logical (OR/ AND) combinations of the ML model with RBC-Info outperformed RBC-Info alone (OR: concordance 92.7%, AUROC 0.93 [0.92–0.95]; AND: concordance 94.6%, AUROC 0.94 [0.93–0.96]). Conclusions A scattergram-based ML model improves the accuracy and reliability of urinary RBC morphological classification based on UF-5000 scattergrams and may help reduce reliance on invasive diagnostics. Prospective, multicenter studies should validate generalizability and assess integration into routine workflows.

Introduction: We aimed to evaluate the impact of lifestyle modifications on the risk of eradication failure in patients undergoing first-line therapy for Helicobacter pylori infection.Methods: A survey was conducted in a community pharmacy to assess changes in alcohol consumption, smoking, and high-fat diet intake before, during, and after first-line therapy for H. pylori infection in enrolled patients.Results: A total of 100 patients (response rate: 3.4%) were included in the analysis. Before therapy, 20 patients (20%) smoked, 35 patients (35%) consumed alcohol, and 91 patients (91%) had a high-fat diet. During therapy, the proportion of patients who changed their habits was 15.0% (3/20) for smoking, 71.4% (25/35) for alcohol consumption, and 28.6% (26/91) for high-fat diet. However, the continuation of these changes post-therapy was minimal.Conclusion: Among patients undergoing first-line therapy for H. pylori infection, lifestyle habits that increase the risk of eradication failure were prevalent, with many patients maintaining their habits during therapy except for alcohol consumption. These findings provide fundamental data for lifestyle counselling during eradication therapy.

Background: Multilocus sequence typing (MLST) is well-established for Pasteurella multocida but remains undeveloped for Pasteurella canis. We established MLST for P. canis using isolates from humans and companion animals in Japan and Korea to gain insights into its population biology. Methods: We analyzed 39 and 22 isolates from companion animals and humans, respectively. We selected seven housekeeping genes—adk, aroA, deoD, gdhA, g6pd, mdh, and pgi—used in P. multocida MLST. Primer pairs for PCR amplification and sequencing were designed based on conserved sites in 10 whole-genome sequences. We determined frag-ment sequences, variable sites, allelic profiles, and sequence types (STs) of each isolate. A phylogenetic tree of concatenated sequences was constructed using the goeBURST algo-rithm to identify STs and clonal complexes (CCs). ompAM, encoding outer membrane protein A, was genotyped for molecular characterization. Results: The sequenced fragment lengths and allele numbers of the seven genes wereHallym University College of Medicine, 424, 451, 483, 439, 429, 419, and 440 bp and 16, 13, 15, 18, 22, 19, and 18, respec-tively. ST1–ST47, including CC2, CC10, CC18, CC31, and CC33, were diversely distributed among the isolates from different hosts/countries. In the seven-gene phylogenetic tree, apart from P. multocida, all isolates clustered together. goeBURST diagrams revealed di-verse ST distributions among different hosts (animal/human) and countries (Japan/Ko-rea/others). We found clusters 1–4 in ompA genotyping, indicating that MLST discrimination is higher than ompA typing discrimination. Conclusions We established MLST for P. canis isolates from humans and companion ani-This is an Open Access article distributed under mals in Japan and Korea, thereby providing a robust tool for population biology studies.

Here, we report a rare case of repeated cardiac trauma caused by self-harm with sewing needles and a literature review. The patient was a 48-year-old female, who repeatedly self-harmed when stressed by inserting a needle into her anterior chest. She had previously undergone three thoracotomy procedures and more than eight procedures for needle removal. In the current case, she visited the hospital due to persistent chest pain after inserting a needle into her left anterior chest. The needle was buried under the skin and could not be seen externally. Computed tomography revealed a 6 cm-long needle, located 1 cm under the skin reaching the right ventricle. Although the patient was hemodynamically stable with no pericardial effusion, emergency surgery was performed due to the possibility that cardiac motion would advance the needle, penetrating the left ventricle, as well as the possibility of additional cardiac injury. Because of repeated thoracotomies and needle-removal procedures, we expected that the patient would have extensive adhesions in the mediastinum, and there was a high risk of cardiac injury with thoracotomy. Therefore, thoracotomy was performed under cardiopulmonary bypass. We performed the thoracotomy while taking care not to advance the needle by monitoring its tip with transesophageal echocardiography. After confirming the position of the needle penetrating the right ventricle, 4-0 monofilament suture with pledget support was sutured around the needle in a U-shape, and the needle was removed. The procedure was completed after confirming the absence of ventricular septal perforation by transesophageal echocardiography.

Objective: To determine the extent of pharmacists’ burden of inquiries from healthcare professionals in community pharmacies. Design: A descriptive cross-sectional study. Methods: A web-based survey was administered to pharmacists affiliated with Medical System Network Group, Inc.’s community pharmacies in Japan. The survey was conducted from February 15 to March 31, 2022. The primary outcome was the burden of inquiries from healthcare professionals and the secondary outcome was the level of burden by job category. Healthcare professionals were defined as physicians, nurses, pharmacists, administrators, care managers, and nursing home staff. To assess the degree of burden, participants were asked “Do you feel burdened by inquiries from health care professionals ? ” and their response was rated on a 5-point Likert scale (not at all, slightly, a little, a lot, and very much). The responses “a lot” and “very much” were combined and defined as “burdened.” To identify the causes of burden, factors of burden and inquiries were investigated. Results: Totally, 1,667 participants were recruited, of which 915 (54.9%) were included in the analysis (women: 62.6%). The participants had a median age of 38 years (interquartile range 31, 48), and worked as pharmacists for 12 years (interquartile range 5, 20). Nearly 13.5% of the respondents felt burdened by inquiries from healthcare professionals and 34.7% reported that physician inquiries were burdensome. The most common reason for feeling burdened was a lack of knowledge about the inquiries (77.3%). Conclusion: It was found that 13.5% of respondents felt burdened when dealing with inquiries from healthcare professionals to pharmacists. In particular, a high percentage of respondents felt burdened by inquiries from physicians. Further research is needed to clarify whether the introduction of a tool that matches the results of this study will reduce the burden of responding to inquiries.

Background/Aims: Endoscopic self-expandable metal stent (SEMS) placement is currently the standard technique for treating unresectable malignant distal biliary obstructions (MDBO). Therefore, covered SEMS with longer stent patency and fewer migrations are required. This study aimed to assess the clinical performance of a novel, fully covered SEMS for unresectable MDBO. Methods: This was a multicenter single-arm prospective study. The primary outcome was a non-obstruction rate at 6 months. The secondary outcomes were overall survival (OS), recurrent biliary obstruction (RBO), time to RBO (TRBO), technical and clinical success, and adverse events. Results: A total of 73 patients were enrolled in this study. The non-obstruction rate at 6 months was 61%. The median OS and TRBO were 233 and 216 days, respectively. The technical and clinical success rates were 100% and 97%, respectively. Furthermore, the rate of occurrence of RBO and adverse events was 49% and 21%, respectively. The length of bile duct stenosis (<2.2 cm) was the only significant risk factor for stent migration. Conclusions The non-obstruction rate of a novel fully covered SEMS for MDBO is comparable to that reported earlier but shorter than expected. Short bile duct stenosis is a significant risk factor for stent migration.

Background/Aims: Mechanical properties (MPs) and axial and radial force (AF and RF) may influence the efficacy and complications of self-expandable metallic stent (SEMS) placement. We measured the MPs of various SEMSs and examined their influence on the SEMS clinical ability. Methods: We evaluated the MPs of 29 types of 10-mm SEMSs. RF was measured using a conventional measurement device. AF was measured using the conventional and new methods, and the correlation between the methods was evaluated. Results: A high correlation in AFs was observed, as measured by the new and conventional manual methods. AF and RF scatterplots divided the SEMSs into three subgroups according to structure: hook-and-cross-type (low AF and RF), cross-type (high AF and low RF), and laser-cut-type (intermediate AF and high RF). The hook-and-cross-type had the largest axial force zero border (>20°), followed by the laser-cut and cross types. Conclusions MPs were related to stent structure. Hook-and-cross-type SEMSs had a low AF and high axial force zero border and were considered safest because they caused minimal stress on the biliary wall. However, the increase in RF must be overcome.

Although cardiac rehabilitation (CR) has been shown to improve exercise tolerance and prognosis in patients with cardiovascular diseases, there remains low participation in outpatient CR. This may be attributed to the patients’ busy schedules and difficulty in visiting the hospital due to distance, cost, avoidance of exercise, and severity of coronary disease. To overcome these challenges, many countries are exploring the possibility of remote CR. Specifically, there is increasing attention on the development of remote CR devices, which allow transmission of vital information to the hospital via a remote CR application linked to a wearable device for telemonitoring by dedicated hospital staff. In addition, remote CR programs can support return to work after hospitalization. Previous studies have demonstrated the effects of remote CR on exercise tolerance. However, the preventive effects of remote CR on cardiac events and mortality remain controversial. Thus, safe and effective remote CR requires exercise risk stratification for each patient, telenursing by skilled staff, and multidisciplinary interventions. Therefore, quality assurance of telenursing and multi-disciplinary interventions will be essential for remote CR. Remote CR may become an important part of cardiac management in the future. However, issues such as costeffectiveness and insurance coverage still persist.

Objective：Only 44 of the 82 university medical schools in Japan have rehabilitation medicine departments, although rehabilitation medicine is one of the 19 basic specialties recognized by the Japanese Medical Specialty Board, and many medical doctors are concerned regarding selecting rehabilitation medicine as a basic specialty without sufficient education in the field. The “Let's Become a Physiatrist” Seminar has been organized since 2017 to eliminate such concerns, and this study aimed to investigate how these results are manifested in the number of majors.Methods：We examined the number of past attendees and tracked how many of them became rehabilitation medicine majors.Results：The number of seminar attendees over a 5-year period was 589. The number of on-demand viewers in FY2020 and FY2021, which were held via the web, was 554. A total of 116 of the 471 physicians who began specialty training in rehabilitation medicine after the seminar was planned attended or web viewed the seminar accounting for 24.63％．This percentage has been increasing each year, with 36.81％ of the majors who applied in 2022 attending the seminar, and the number of multiple attendees also increased. The number of majors has increased significantly doubling to 144 in 2022 compared with 74 in 2018.Conclusion：In many cases, the seminar helped the attendees learn more about physiatrists and develop their thoughts while attending multiple times. Thus, they started their majors. Five years have passed since we started planning this seminar, and we believe that the results are now coming to fruition.
