Self-Reported Time-at-Bedside and Its Association with In-Training Examination Scores of Residents in Japan.

Background: Time-at-bedside plays a central role in clinical medicine. However, the amount of time Japanese clinical residents spend at patients' bedsides remains unexplored.

Objective: To quantify time-at-bedside and examine its association with in-training examination scores during clinical residency in Japan.

Preventable diagnostic errors of lower gastrointestinal perforation: a secondary analysis of a large-scale multicenter retrospective study.

Background: Lower gastrointestinal perforation (LGP) is an acute abdominal condition associated with a high mortality rate. Timely and accurate diagnosis is crucial. Nevertheless, a diagnostic delay has been estimated to occur in approximately one-third of the cases, and the factors contributing to this delay are yet to be clearly understood.

A Case of Squamous Cell Carcinoma of the Breast Occurring in Benign Phyllodes Tumor.

A 49-year-old woman visited our hospital after noticing an enlarged left breast mass. After a biopsy, she was diagnosed with fibroadenoma and underwent tumor resection. Postoperative pathology revealed squamous cell carcinoma (SCC) within a benign phyllodes tumor.

Residency Program Directors' Perspectives on Overtime Duty Hours and Professional Development Time in Japan.

Purpose: This study aimed to explore the perspectives of residency program directors in Japan regarding overtime duty hours and the balance between clinical training and self-improvement activities. This study explores the impact of work-hour regulations on resident well-being and training quality, contributing to global discourse on medical education reform.

Participants And Methods: A cross-sectional survey was distributed to 701 residency training hospitals across Japan to investigate their readiness for new duty-hour limits under the Medical Care Act, which categorizes working hours into Level A (960 hours/year), Level B (1440 hours/year), and Level C-1 (1920 hours/year).

A novel resident physician examination using clinical simulation video to assess clinical competence in Japan: a cross-sectional study.

Background: The general medicine in-training examination (GM-ITE) assesses physicians' clinical knowledge. This study expanded on findings from a previous pilot study to assess the relationship between general medicine in-training examination (GM-ITE) scores and the diagnostic skills of resident physicians in Japan by employing an innovative clinical simulation video (CSV-IE).

Methods: This multicenter cross-sectional study included 4,677 resident physicians who took the GMITE between January 17 and 30, 2023.

The relation between resident mentorship and in-training examination scores: A nation-wide, cross-sectional study in Japan.

Background: Mentorship is a dynamic reciprocal relationship, wherein a novice (mentee) grows with the encouragement of an advanced careerist (mentor). It is widely implemented in medical training programs. However, there are few reports on mentorship's educational effects in the Japanese context.

Accumulation of endogenous Muse cells in the myocardium and its pathophysiological role in patients with fulminant myocarditis.

Multi-lineage differentiating stress-enduring (Muse) cells, identified as pluripotent surface marker SSEA-3(+) cells, are stress tolerant endogenous pluripotent-like stem cells, and are involved in tissue repair. However, the significance of Muse cells in acute myocarditis has not been evaluated. In the present study, we counted Muse cells/area in biopsied myocardial tissue samples from 17 patients with fulminant myocarditis, and 6 with non-inflammatory myocardial disease as controls.

A case of pulmonary mucosa-associated lymphoid tissue lymphoma diagnosed by detecting t(11;18)(q21;q21) in bronchial lavage fluid.

A 76-year-old woman was diagnosed with mucosa-associated lymphoid tissue (MALT) lymphoma by upper gastrointestinal endoscopy. She underwent further investigation for concomitant bilateral pleural effusions and right pulmonary consolidation. MALT lymphoma with the t(11; 18)(q21; q21) translocation and were detected in pleural fluid.

Impact of disclosing a working diagnosis during simulated patient handoff presentation in the emergency department: correctness matters.

Introduction: Diagnostic errors in emergency departments (ED) are a significant concern and exacerbated by cognitive biases during patient handoffs. The timing and accuracy of disclosing working diagnoses during these handoffs potentially influence diagnostic decisions, yet empirical evidence remains limited.

Materials And Methods: This parallel, quasi-experimental study involved 40 interns from Japanese teaching hospitals, randomly assigned to control or intervention groups.

Successful Rapid Benzodiazepine Detoxification in an Acute Care Hospital: A Case Report.

Introduction: Benzodiazepine (BZD) dependence and withdrawal are significant public health concerns, affecting 15-30% of regular users within 4-6 weeks of administration. Rapid BZD tapering protocols in acute care settings can mitigate withdrawal symptoms and facilitate rehabilitation, yet are challenging due to variability in patient responses.

Case Presentation: We report a case of a 67-year-old male with a history of high-dose BZD use for panic disorder and depression and recent mild ischemic stroke, presenting with worsening left lower limb paralysis.

Usefulness of color Doppler and strain elastography adjunctive to B-mode ultrasonography in the diagnosis of non-mass abnormalities of the breast: results of the BC-07 multicenter study of 385 cases.

Purpose: The concept of non-mass abnormalities of the breast has been employed in Japan for approximately 20 years. Although B-mode findings are classified as non-mass abnormalities, the usefulness of adding color Doppler ultrasonography (US) and strain elastography to B-mode US is unclear. Therefore, we conducted a multicenter study (JABTS BC-07) to establish the diagnostic criteria for breast US, including color Doppler and elastography, for non-mass abnormalities of the breast and verify their diagnostic usefulness.

Unexpected Sudden Deaths Following the Co-administration of Ceftriaxone and Lansoprazole: A Case Series.

Ceftriaxone and lansoprazole are commonly used in clinical settings, but recent analyses indicate a potential risk for QTc prolongation and cardiac events when used together. This case series examines three patients from a cohort of sudden death cases at a single institution over a decade, who received both medications within 24 hours before death. Three cases were identified, each with contributing factors for cardiac arrhythmias.
