Cardiomyopathy Associated with CD36 Deficiency: Role of F-Fluorodeoxyglucose Positron Emission Tomography in the Diagnosis.

We herein report a patient with type I CD36 deficiency. The patient was initially suspected of having isolated cardiac sarcoidosis based on the presence of non-sustained ventricular tachycardia, delayed myocardial enhancement on magnetic resonance imaging (MRI), and diffuse accumulation of F-fluorodeoxyglucose (F-FDG) on cardiac positron emission tomography (PET). Our findings suggest that the diagnosis of cardiomyopathy associated with CD36 deficiency is often missed, highlighting the importance of a differential diagnosis of isolated cardiac sarcoidosis.

Fatal Arrhythmic Risks in Cardiac Sarcoidosis With Mildly Impaired Cardiac Function.

Background: The prognosis and later fatal arrhythmia in cardiac sarcoidosis (CS) with relatively preserved cardiac function were unclear.

Objectives: This study aimed to evaluate the prognosis and arrhythmic events in patients with CS and mildly impaired cardiac function.

Methods: Data were collected from a nationwide Japanese cohort survey conducted in 57 hospitals (n = 420); 322 patients with CS with left ventricular ejection fraction (LVEF) >35% were investigated.

Survey on digital dependency, writing by hand, and group learning as learning styles among Japanese medical students: Assessing correlations between various accomplishments.

Background: Although digital learning devices have become increasingly more common in medical education settings, it remains unclear how they influence medical student learning styles and various outcome measures. This study aimed to assess student learning styles, specifically as they relate to digital dependency, writing habits, and group learning practices among current medical students.

Materials And Methods: This questionnaire study was approved by the Research Ethics Committee of Osaka Medical and Pharmaceutical University.

The characteristics of Japanese guidelines on diagnosis and treatment of cardiac sarcoidosis compared with the previous guidelines.

Sarcoidosis in Japanese sarcoidosis is characterized by a high prevalence of cardiac involvement. In this regard, cardiac sarcoidosis (CS) continues to be an important focus of study among physicians caring for sarcoidosis in Japan. The Japanese Ministry of Health, Labor and Welfare (MHLW) and Japan Society of Sarcoidosis and other Granulomatous Disorders (JSSOG) have published clinical guidelines aiming to assist clinical practices.

Comparison of Younger and Older medical student performance outcomes: A retrospective analysis in Japan.

The present study examined the impact of age on medical student repeat-year experience and performance outcomes on the objective structured clinical examination (OSCE), Clinical Clerkship (CC), and other relevant examinations in the Japanese medical school system. This retrospective analysis examined the number of students with repeat-years and the years required to graduate, stratifying students by the age they entered medical school (Younger: within 4 years of high school graduation; Older: 5 or more years after high school graduation). Scores of the Pre-CC OSCE, Computer-based testing (CBT), CC performance, CC integrative test, and graduation exams were compared among those graduating from our medical school between 2018 and 2020, and examined correlations between student age and performance outcomes.

Prognosis and Outcomes of Clinically Diagnosed Cardiac Sarcoidosis Without Positive Endomyocardial Biopsy Findings.

Background: Diagnosis of cardiac sarcoidosis (CS) is sometimes difficult due to a low positive rate of epithelioid granulomas by endomyocardial biopsy (EMB). Accordingly, Japanese guidelines can allow the CS diagnosis using clinical data alone without EMB results (clinical CS) since 2006. However, little is known about prognosis and outcome of clinical CS.

Features and Outcomes of Histologically Proven Myocarditis With Fulminant Presentation.

Background: Fulminant myocarditis presentation (FMP) is a rare and severe presentation of myocarditis. The natural history of FMP and its clinical features associated with poor outcomes are incompletely understood because there is a lack of generalizable evidence.

Methods: This multicenter retrospective cohort study included patients hospitalized with histologically proven myocarditis who underwent catecholamine or mechanical support from 235 cardiovascular training hospitals across Japan between April 2012 and March 2017.

Gender differences in repeat-year experience, clinical clerkship performance, and related examinations in Japanese medical students.

While the number of female medical students is increasing in Japan, gender differences in medical school performance have not been studied extensively. This study aimed to compare gender differences in repeat-year experience, Clinical Clerkship (CC) performance, and related examinations in Japanese medical students. We retrospectively analyzed the number of repeat-year students and years to graduation for male and female medical students, and assessed gender differences in performance on computer-based testing (CBT) before CC, CC as evaluated by clinical teachers, the CC integrative test, and the graduation examination in 2018-2020 graduates from our medical school.

Sex-related differences in the prognosis of patients with cardiac sarcoidosis treated with cardiac resynchronization therapy.

Background: Past studies have shown the sex-related difference in the efficacy of cardiac resynchronization therapy (CRT). However, the data for cardiac sarcoidosis (CS) are limited.

Objective: The purpose of this study was to assess the sex-related prognostic differences in CS patients with CRT.

Myocardial findings evaluated by echocardiography in cardiac sarcoidosis: A report of seven cases.

Sarcoidosis is a multisystem granulomatous disease of unknown cause. With cardiac sarcoidosis (CS), patients represent a wide range of cardiac manifestations from subtle to overt morphological and functional abnormalities. The advent of ultrasound technologies has enabled to identify not only typical findings to CS such as basal thinning of the ventricular septum, but also subclinical myocardial alterations.

Correlation of student performance on clerkship with quality of medical chart documentation in a simulation setting.

Background: Medical chart documentation is an essential skill acquired in a clinical clerkship (CC). However, the utility of medical chart writing simulations as a component of the objective structured clinical examination (OSCE) has not been sufficiently evaluated. In this study, medical chart documentation in several clinical simulation settings was performed as part of the OSCE, and its correlation with CC performance was evaluated.

A text mining analysis of perceptions of the COVID-19 pandemic among final-year medical students.

Aim: The coronavirus disease 2019 (COVID-19) pandemic has presented various challenges to medical schools. We performed a text mining analysis via essay task to clarify perceptions among final-year medical students toward the COVID-19 pandemic.

Methods: We posed the following essay question to 124 final-year medical students: "What should medical staff do during the COVID-19 pandemic; what should you do?" Responses were subjected to quantitative analysis using a text mining approach.

A Patient with Cardiac Sarcoidosis in Whom an Abnormal Myocardial Uptake of Fluorine-18 Fluorodeoxyglucose and Sustained Ventricular Tachycardia Recurred 3.5 Years after Discontinuing Oral Corticosteroid Therapy.

We herein report a woman diagnosed with cardiac sarcoidosis (CS) based on the presence of epithelioid granulomas in non-cardiac organs and clinical findings including sustained ventricular tachycardia (VT) and cardiac dysfunction. She stopped oral corticosteroid after 4 years of treatment, and an abnormal myocardial uptake of fluorine-18 fluorodeoxyglucose and sustained VT recurred 3.5 years later.

Relationships between objective structured clinical examination, computer-based testing, and clinical clerkship performance in Japanese medical students.

Background: It is unclear how comprehensive evaluations conducted prior to clinical clerkships (CC), such as the objective structured clinical examination (OSCE) and computer-based testing (CBT), reflect the performance of medical students in CC. Here we retrospectively analyzed correlations between OSCE and CBT scores and CC performance.

Methods: Ethical approval was obtained from our institutional review board.

Clinical Features and Histopathology of Cardiac Sarcoidosis with Refractory Heart Failure: An Autopsy Case.

Treatment involving the insertion of an implantable cardioverter defibrillator and cardiac resynchronization therapy devices has markedly improved the prognosis of cardiac sarcoidosis. However, the prognosis remains poor in patients with advanced cardiac dysfunction or heart failure. We herein report the clinical course and histopathological findings of the autopsied heart of a patient with cardiac sarcoidosis with long-term refractory heart failure.

Atrial Arrhythmias and Atrial Involvement in Cardiac Sarcoidosis.

Severe ventricular arrhythmias such as high-grade atrioventricular block and ventricular tachycardia may cause lethal conditions or sudden death in patients with cardiac sarcoidosis (CS). Physicians should examine patients carefully for these conditions and treat them appropriately. As arrhythmias are being better diagnosed and treated, physicians are increasingly aware of atrial arrhythmias, which have not been focused upon as CS-related conditions, in patients with CS.

Case of isolated cardiac sarcoidosis diagnosed by newly developed abnormal uptake during serial follow-up fluorine-18 fluorodeoxyglucose positron emission tomography.

Cardiac sarcoidosis (CS) causes lethal arrhythmia and heart failure and has a poor prognosis; therefore, early detection and early stage treatment are important. However, diagnosis of isolated CS may be difficult in some cases owing to the low sensitivity of myocardial biopsy. Herein, we describe the case of a patient with isolated CS, showing change from negative to positive fluorine-18 fluorodeoxyglucose ( F-FDG) positron emission tomography (PET) uptake results within 9 months.
