Urothelial carcinoma occurring in a defunctionalized bladder after urinary diversion due to the bladder exstrophy-epispadias complex.

Introduction: The bladder exstrophy-epispadias complex is a rare congenital disease. Urothelial carcinomas rarely occur in patients with this disease, and there have been few reports on its treatment.

Case Presentation: We report the case of a 44-year-old man with a hemorrhage from the external urethral meatus.

Successful treatment with enfortumab-vedotin of metastatic signet ring cell cancer expressing nectin-4 and originating from the bladder.

Introduction: As an aggressive adenocarcinoma phenotype, primary signet ring cell carcinoma of the urinary bladder is an extremely rare variant. The prognosis of metastatic signet ring cell carcinoma of the urinary bladder is extremely poor and the clinical course for its specific pathogenesis remains unelucidated.

Case Presentation: A 64-year-old Japanese male patient was diagnosed with invasive urothelial carcinoma with glandular differentiation of a signet ring cell-type with pT4aN0M0, and he was eventually diagnosed with metastatic signet ring cell carcinoma of the urinary bladder.

Endothelial cells regulate alveolar morphogenesis by constructing basement membranes acting as a scaffold for myofibroblasts.

Alveologenesis is a spatially coordinated morphogenetic event, during which alveolar myofibroblasts surround the terminal sacs constructed by epithelial cells and endothelial cells (ECs), then contract to form secondary septa to generate alveoli in the lungs. Recent studies have demonstrated the important role of alveolar ECs in this morphogenetic event. However, the mechanisms underlying EC-mediated alveologenesis remain unknown.

Renal cell carcinoma with multiple bone metastases effectively treated by a combination of tyrosine kinase inhibitor, robot-assisted partial nephrectomy, and metastasectomy.

Key Clinical Message: Maintaining a disease-free status for a long time in cases of renal cell carcinoma with multiple bone metastases and repeated recurrences is challenging. What matters most in the multidisciplinary approach is the treatment strategy. Although this is a case where multidisciplinary treatment resulted in long-term CR during the TKI era, the treatment strategy is still relevant now that treatment options have increased.

Upper Respiratory Symptoms as Long COVID: Insight from a Multicenter Cohort Study.

Objective: This study aimed to investigate the clinical features of long COVID cases presenting with upper respiratory symptoms, a topic not yet fully elucidated.

Study Design: Prospective cohort study.

Setting: A multicenter study involving 26 medical facilities in Japan.

Impact of HIF prolyl hydroxylase inhibitors in heart failure patients with renal anemia.

Objective: Hypoxia-inducible factor prolyl hydroxylase (HIF-PH) inhibitors are a new class of anti-anemia agents. We retrospectively evaluated the safety and efficacy of HIF-PH inhibitors in patients with heart failure (HF) complicated by anemia associated with chronic kidney disase. HIF-PH inhibitor treatment was initiated in 32 patients with chronic HF complicated by renal anemia and were followed up for 3 months.

Comparison of novel intrinsic versus conventional antitachycardia pacing for ventricular tachycardia among implantable cardioverter-defibrillator recipients.

Introduction: Intrinsic antitachycardia pacing (iATP) is a novel automated antitachycardia pacing (ATP) that provides individual treatment to terminate ventricular tachycardia (VT). However, the clinical efficacy of iATP in comparison with conventional ATP is unknown. We aim to compare the termination rate of VT between iATP and conventional ATP in patients with implantable cardioverter-defibrillators using a unique setting of different sequential orders of both ATP algorisms.

Midterm outcomes of transcatheter aortic valve replacement in patients with active cancer.

Objectives: The clinical outcomes of transcatheter aortic valve replacement (TAVR) in patients with aortic stenosis (AS) and concomitant active cancer remain insufficiently explored. This study aimed to assess the midterm outcomes of TAVR in patients diagnosed with AS and active cancer.

Methods: Data from the OCEAN-TAVI, a prospective Japanese registry of TAVR procedures, was analysed to compare prognoses and clinical outcomes in patients with and without active cancer at the time of TAVR.

Impact of an angulated aorto-septal relationship on cardio-cerebrovascular outcomes in patients undergoing hemodialysis.

Aortic and valvular calcification are well-known risk factors for cardio-cerebrovascular events in patients undergoing hemodialysis. We investigated the clinical impact of an angulated aorto-septal angle as a result of aortic elongation due to aortic calcification on cardio-cerebrovascular outcomes in patients undergoing hemodialysis. We investigated 306 patients (mean age 65.

Prognostic impact of polypharmacy and discharge medications in octogenarians and nonagenarian patients with acute heart failure.

With the increasing frequency of heart failure (HF) in elderly patients, polypharmacy has become a major concern owing to its adverse outcomes. However, reports on the clinical impact of polypharmacy and discharge medications in hospitalized super-aged patients with acute HF are rare. Data from 682 patients aged 80 years or older, hospitalized for treating acute HF, were analyzed.

Steroid reduction-resistant pulmonary involvement with Sweet's syndrome suspected of being vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic syndrome: A case report.

In cases of Sweet's syndrome with pulmonary involvement, fever of unknown origin, and macrocytic anaemia, VEXAS syndrome can be considered in the differential diagnosis. A 67-year-old man who was taking prednisolone for a fever of unknown origin and Sweet's syndrome was referred to us because of an abnormal chest shadow. Computed tomography revealed a nonfibrotic hypersensitivity pneumonitis-like opacity, and blood test results indicated macrocytic anaemia.

Effects of ipragliflozin on left ventricular diastolic function in patients with type 2 diabetes: A sub-analysis of the PROTECT trial.

Background: We hypothesized that the beneficial effects of sodium-glucose cotransporter-2 (SGLT2) inhibitors on diastolic function might depend on baseline left ventricular (LV) systolic function.

Methods: To investigate the effects of SGLT2 inhibitors on LV diastolic function in patients with type 2 diabetes mellitus (T2DM), we conducted a post-hoc sub-study of the PROTECT trial, stratifying the data according to LV ejection fraction (LVEF) at baseline. After excluding patients without echocardiographic data at baseline or 24 months into the PROTECT trial, 31 and 38 patients with T2DM from the full analysis dataset of the PROTECT trial who received ipragliflozin or no SGLT2 inhibitor (control), respectively, were included.

Protocol for the isolation of GFP-expressing ferroptosis-dependent extracellular vesicles in in vitro cell culture models.

Extracellular vesicles (EVs) are complex structures that transport various DNA, RNA, and protein. Recently, new EV secretion mechanisms have been identified through the iron regulatory system in mammalian cells. We revealed that ferroptosis increases EV secretion, which is named ferroptosis-dependent EVs (FedEVs).
