Background: Protein-energy wasting (PEW), a unique weight loss linked to nutritional and metabolic abnormalities, is common in patients undergoing hemodialysis (HD) and associated with adverse outcomes. This study investigated whether extended-hours HD combined with a liberalized diet could overcome PEW and improve survival.
Methods: The body mass index (BMI) and survival outcomes in patients undergoing extended-hours HD were evaluated for up to 8 years using data from the LIBeralized diet Extended-houRs hemodialysis Therapy (LIBERTY) cohort.
This manuscript details the development and implementation of Mongolia's first official training program for child and adolescent psychiatry (CAP) specialists. This initiative, inspired by and developed in collaboration with Japanese CAP training models, addresses the substantial gap in specialized mental health services for children and adolescents in Mongolia. Our discussion elaborates on the collaborative efforts between the Mongolian National University of Medical Sciences, Nagoya University, and other partnering institutions, reflecting on the initial outcomes and the strategic importance of this program.

Dynamic chest radiography (DCR) can estimate haemodynamic parameters in heart failure (HF). However, no studies have evaluated its ability to determine cardiac systolic function in HF. This experimental study investigates the correlation between left ventricular (LV) ejection fraction (LVEF) and DCR image parameters in HF.

Background: Acute decompensated heart failure (ADHF) leads to hospitalizations and functional decline in older adults. Although cardiac rehabilitation (CR) is effective for stable heart failure, its impact on ADHF patients, particularly those without frailty, is unclear.
Objectives: The goal of this study was to evaluate the efficacy and safety of early in-hospital CR for patients hospitalized with ADHF who are not frail.

Methods And Results: The REAL-CAD (Randomized Evaluation of Aggressive or Moderate Lipid Lowering Therapy With Pitavastatin in Coronary Artery Disease) study is a prospective, multicenter, randomized trial of high-dose (pitavastatin 4 mg/day) or low-dose (pitavastatin 1 mg/day) statin therapy in 12 118 patients with chronic coronary syndrome. The primary end point was a composite of cardiovascular death, nonfatal myocardial infarction, stroke, or unstable angina requiring hospitalization (major adverse cardiac and cerebral events [MACCE]).

Background: Removal of cardiac implantable electronic devices (CIEDs) is strongly recommended for CIED-related infections, and leadless pacemakers (LPs) are increasingly used for reimplantation. However, the optimal timing and safety of LP implantation after CIED removal for infection remains unclear.This systematic review and meta-analysis aimed to assess complication rates (all-cause mortality and reinfection) when LP implantation was performed simultaneously with or after CIED removal.

Tissue-level oscillation is achieved by tissue-intrinsic clocks along with network-dependent signals originating from distal organs and organismal behavior. Yet, it remains unexplored whether maternal circadian rhythms during pregnancy influence fetal rhythms and impact long-term susceptibility to dietary challenges in offspring. Here, we demonstrate that circadian disruption during pregnancy decreased placental and neonatal weight yet retained transcriptional and structural maturation.

Aims: This study aimed to investigate the relationship between corticosteroid therapy and long-term outcomes in patients with cardiac sarcoidosis, stratified by left ventricular ejection fraction (LVEF) at diagnosis.
Methods And Results: This study conducted a analysis of the ILLUstration of the Management and prognosIs of JapaNese PATiEnts with Cardiac Sarcoidosis, a retrospective multicentre registry. Cardiac sarcoidosis was diagnosed based on the 2016 Japanese Circulation Society and 2014 Heart Rhythm Society criteria.

Background: The prognostic implications of cerebral microbleeds (CMBs) in patients who undergo transcatheter aortic valve replacement (TAVR) have not been fully elucidated. Therefore, we aimed to investigate the association between the presence of CMBs and adverse outcomes post-TAVR.
Methods: In this single-center retrospective study, we included 124 patients who underwent brain magnetic resonance imaging before TAVR.
Introduction: Patients with metastatic renal cell carcinoma have a poor prognosis and its specific pathogenesis remains unelucidated.
Case Presentation: At 78 years of age, a Japanese male patient was diagnosed with metastatic renal cell carcinoma (cT3N2M1 stage) and multiple brain metastases that were responsive to stereotactic radiation therapy followed by systemic combination induction therapy of pembrolizumab plus lenvatinib. Adverse events, including grade 3 hypertension, grade 2 eruption, and elevated grade 2 fever, were controlled by a dose reduction or suspension of drugs.

Background: Hypertension is common in patients with heart failure with mildly reduced or preserved ejection fraction (HFmrEF/HFpEF), and current guidelines recommend treating systolic blood pressure (SBP) to a target <130 mm Hg. However, data supporting treatment to this target are limited. Additionally, pulse pressure (PP), a marker of aortic stiffness, has been associated with increased risk of cardiovascular events, but its prognostic impact in HFpEF has not been extensively studied.

Background: MET gene exon 14 skipping was identified as a potential driver mutation that occurs in approximately 3%-4% of patients with nonsmall cell lung cancer (NSCLC), typically in the absence of other driver mutations. Capmatinib and tepotinib were the first MET- tyrosine kinase inhibitors (MET-TKIs) approved by the FDA and PMDA, specifically for patients with metastatic NSCLC. Several studies have reported acquired resistance after MET-TKI treatment for MET mutation-positive NSCLC.

Background: The importance of nutritional status is underappreciated in patients with heart failure (HF). This study aimed to describe the range of the prognostic nutrition index (PNI), and the clinical characteristics and outcomes according to PNI, in patients with HF with preserved ejection fraction (HFpEF) and reduced ejection fraction (HFrEF). The primary outcome was the composite of HF hospitalization or cardiovascular death.

Background: To evaluate whether sodium zirconium cyclosilicate (SZC) enables the up-titration of spironolactone without increasing the risk of hyper- and hypokalemia in patients with heart failure with reduced and mildly reduced ejection fraction (HFrEF and HFmrEF) and moderate/severe chronic kidney disease (CKD) who developed hyperkalemia during treatment with suboptimal spironolactone dose.
Methods: The REGISTA-K is a randomized, double-blind, placebo-controlled, multicenter trial that examined the efficacy and safety of SZC in up-titrating spironolactone without the occurrence of hyperkalemia or hypokalemia. A total of 266 patients with HFrEF and HFmrEF and hyperkalemia will be randomized in a 1:1 ratio to receive either SZC or placebo after treating hyperkalemia with SZC at 25 sites in Japan.
Previous studies have described two distinct vascular systems in cetacean fins. However, these studies have been limited to Delphinoidea species, with little information on their three-dimensional structures. In this study, the anatomical analysis of the caudal and dorsal fins of a dwarf sperm whale was conducted using X-ray computed tomography and gross dissection with staining, providing the first confirmation of the two vascular systems in the fins of the family Kogiidae.

Ventricular tachycardia (VT) is a severe arrhythmia commonly treated with implantable cardioverter defibrillators, antiarrhythmic drugs and catheter ablation (CA). Although CA is effective in reducing recurrent VT, its impact on survival remains uncertain, especially in patients with extensive scarring. Stereotactic arrhythmia radioablation (STAR) has emerged as a novel treatment for VT in patients unresponsive to CA, leveraging techniques from stereotactic body radiation therapy used in cancer treatments.
View Article and Find Full Text PDFBackground: Visualizing the specific regions where atrial fibrillation (AF) is maintained is crucial for effective treatment, but it remains challenging in clinical practice. We aimed to address this challenge by developing a mapping approach focused on the cycle length (CL) and its gradient (CL-gradient).
Methods: In 105 patients undergoing initial ablation for persistent AF, pre-ablation CARTOFINDER data were utilized to create maps based on three indicators: (1) CL, the atrial frequency during AF calculated using CARTOFINDER; (2) Short CL, encompassing CLs within 5 ms of the minimum CL; and (3) CL-gradient, the CL range within a 6 mm radius.
