Usefulness of the "En face view" method for diagnosing perimembranous ventricular septal defects.

Background: Perimembranous ventricular septal defect (VSD) can be classified as having trabecular, inlet, or outlet extension. The surgical approach used in patch closure depends on the which valve of the tricuspid valve to suture around and the avoidance of the specialized conducting system. This retrospective study evaluated the usefulness of the "En face view" method for classifying perimembranous VSD.

Four cardiomyopathy patients with a heterozygous DSG2 p.Arg119Ter variant.

DSG2, encoding desmoglein-2, is one of the causative genes of arrhythmogenic cardiomyopathy. We previously identified a homozygous DSG2 p.Arg119Ter stop-gain variant in a patient with juvenile-onset cardiomyopathy and advanced biventricular heart failure.

A case report of pre-implantation feasibility test for combining leadless pacemaker and subcutaneous implantable cardioverter-defibrillator in adult congenital heart disease.

Unlabelled: New cardiac implantable electronic devices (CIEDs), such as leadless pacemakers and subcutaneous implantable cardioverter defibrillators (S-ICDs), are being used in patients with adult congenital heart disease. The selection of CIEDs often requires careful consideration due to technical challenges posed by a unique heart structure. A 27-year-old man following a surgical tetralogy of Fallot (TOF) repair developed non-sustained ventricular tachycardia, sick sinus syndrome, and complete atrioventricular block.

Excessive supraventricular ectopic activity is a simple cutoff for predicting late recurrence of atrial fibrillation after ablation.

The relationship between post-ablation excessive supraventricular ectopic activity (ESVEA), a new marker for new-onset atrial fibrillation (AF), and late AF recurrence is uncertain. We enrolled 469 patients with AF who underwent initial radiofrequency catheter ablation and 24-h Holter monitoring the day after. Early AF recurrence (n = 57; 12%) and ESVEA (n = 242; 52%) were noted.

Clinicopathological and molecular characteristics of papillary thyroid carcinoma in adolescent and young adult patients.

Adolescent and young adult (AYA, 15-39 years old) patients with papillary thyroid carcinoma (PTC) experience significant psychological distress and place great importance on obtaining information regarding the disease; however, their demands remain unmet. We aimed to investigate clinicopathological and molecular features of PTC in AYA patients and compare them to those of PTC in older patients (≥40 years). This retrospective study enrolled 1,677 patients diagnosed with PTC from January 2018 to December 2022, with 400 AYA patients and 1,277 older adults.

Long-term survival after conversion surgery for an esophageal neuroendocrine carcinoma: a case report.

Background: Esophageal neuroendocrine carcinomas (NECs) are extremely rare. Published information on their clinical features, pathological findings, and prognosis is lacking. The optimal treatment for esophageal NECs has not yet been determined because they appear extremely malignant histologically and have a poor prognosis.

Association Between Gross Features and Coexistence of and Promoter Mutations in Papillary Thyroid Carcinomas: A Combined Analysis Incorporating Clinicopathologic Features.

The coexistence of v-Raf murine sarcoma viral oncogene homolog B1 () and telomere reverse transcriptase promoter (-p) mutations is considerably associated with aggressiveness and poor prognosis in papillary thyroid carcinoma (PTC). However, the association between gross findings and genetic alterations in PTC remains unknown. We aimed to investigate the association between clinicopathologic features, including macroscopic features, and the coexistent and -p mutations in patients with PTC.

Neuron-selective and activity-dependent splicing of BDNF exon I-IX pre-mRNA.

Brain-derived neurotrophic factor (BDNF) is essential for numerous neuronal functions, including learning and memory. The expression of BDNF is regulated by distinctive transcriptional and post-transcriptional mechanisms. The Bdnf gene in mice and rats comprises eight untranslated exons (exons I-VIII) and one exon (exon IX) that contains the pre-proBDNF coding sequence.

A case report: pitfalls in antibacterial therapy with rifampicin for mechanical valve endocarditis-the king of drug interactions.

Background: Rifampicin is a strong inducer of the hepatic cytochrome P450 (CYP) family and is known to interact with many clinical drugs. However, to our knowledge, no case of worsening heart failure (HF) due to the interaction between rifampicin and HF drugs has been reported.

Case Summary: A 32-year-old female, who had undergone intracardiac repair for an incomplete atrioventricular septal defect with dextrocardia and prosthetic valve replacements for right and left atrioventricular valve regurgitation, presented as an outpatient.

Initiation of a Screening Program: Enhancing Healthcare at Juntendo University.

Objectives: We started () screening program of students at Juntendo university in 2020. We report the current status of screening program and the outcomes of screening program.

Methods: The students of the School of the Faculty of Health Sciences of Juntendo University enrolling in the spring of 2020-2022 were recruited for this study.

Ratio of pulmonary artery diameter to ascending aortic diameter and its association with right ventricular failure after left ventricular assist device implantation.

Background: Several invasive hemodynamic parameters help predict right ventricular failure (RVF) after left ventricular assist device (LVAD) implantation. However, prediction using non-invasive parameters alone has not been established. The ratio of the diameters of the pulmonary artery (PAD) to those of the ascending aorta (AoD) may indicate past hemodynamic load and cardiac dysfunction.

Significance of P53-Binding Protein 1 as a Novel Molecular Histological Marker for Hypopharyngeal Squamous Neoplasms.

The DNA damage response protein p53-binding protein 1 (53BP1) accumulates and forms foci at double-strand DNA breaks, indicating the extent of DNA instability. However, the potential role of 53BP1 as a molecular biomarker for hypopharyngeal squamous cell carcinoma (HPSCC) diagnosis remains unknown. Here, we evaluated the potential of immunofluorescence-based analysis of 53BP1 expression to differentiate the histology of hypopharyngeal neoplasms.

Long-term prognosis and DNA damage status after oral mucosal epithelial cell sheet transplantation following esophageal endoscopic submucosal dissection for squamous cell carcinoma: A case series.

Autologous oral mucosal epithelial cell sheet (AOMECS) transplantation has recently been applied in human patients to prevent postprocedural stenosis following endoscopic submucosal dissection (ESD) for esophageal squamous cell carcinoma. However, the long-term safety of AOMECS transplantation remains unclear. We evaluated the long-term outcomes of 10 patients who participated in a clinical trial of AOMECS transplantation after esophageal ESD.

Case Study of a Refractory Idiopathic Peptic Ulcer in Which 24-h Intragastric pH Monitoring Contributed to Its Pathophysiological Analysis.

Introduction: In recent years, the frequency of idiopathic peptic ulcers (IPUs) has increased. However, the clinicopathological characteristics of IPU have not been fully elucidated and treatment methods for recurrent and refractory cases have not yet been established.

Case Presentation: A man in his forties complained of epigastric discomfort.

Utility of Adjunctive Impella Support to Venoarterial Extracorporeal Membrane Oxygenation for a Refractory Electrical Storm.

Venoarterial extracorporeal membrane oxygenation (VA-ECMO) stabilizes hemodynamics in an electrical storm leading to cardiogenic shock. However, adverse effects of VA-ECMO are increased left ventricular (LV) afterload and LV end-diastolic pressure due to retrograde blood return. These adverse effects could be ameliorated by LV unloading with Impella insertion.

The foremost and greatest barrier to end-stage heart failure treatment: the impact of caregiver shortage.

We examined the number of patients abandoning cardiac replacement therapy due to the inability to secure a designated caregiver. At Osaka University Hospital Heart Center, when we receive a consultation for a patient with severe heart failure from another hospital, a heart failure team makes a visit to the referring hospital as soon as possible. We retrospectively analyzed this hospital-visit database.

F-fluorodeoxyglucose positron emission tomography/computed tomography parameters are associated with histological outcomes in superficial esophageal squamous cell carcinoma.

Endoscopic submucosal dissection is a standard treatment for early esophageal squamous cell carcinoma. However, submucosal or lymphovascular invasion increases the risk of lymph node metastasis. Although F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) parameters are associated with prognosis in patients with advanced esophageal squamous cell carcinoma, the utility of FDG PET/CT in diagnosing superficial esophageal carcinoma remains unclear.
