Article Synopsis
  • This study examined how left ventricular ejection fraction (LVEF) changes after a specific heart valve repair procedure called transcatheter edge-to-edge valve repair (TEER) in patients with mitral regurgitation (MR).
  • Findings revealed that 32% of patients experienced worsened LVEF after the procedure, linked to increased end-systolic volumes in the heart and certain predictors like higher LVEF and levels of B-type natriuretic peptide.
  • Despite the LVEF worsening, long-term outcomes (like death or hospitalization for heart failure) were similar for both patients with worsened and preserved LVEF, indicating that LVEF change might not significantly impact overall health results post-TEER

Introduction: Systemic sclerosis is a rare autoimmune connective tissue disease characterised by (1) microvasculopathy; (2) immune dysregulation; and (3) progressive fibrosis of the skin and internal organs. Soluble guanylate cyclase plays an important role in maintaining vascular and immunological homeostasis and preventing organ fibrosis. Pharmacological modulation of soluble guanylate cyclase with soluble guanylate cyclase stimulators has shown anti-inflammatory and antifibrotic effects in animal models of systemic sclerosis, with a trend towards clinical efficacy in a Phase II study (RISE-SSc).

Sangyo Eiseigaku Zasshi

January 2025

The committee members for Allergy and Immunotoxicology (AIT), Japan Society for Occupational Health (JSOH).

Background: According to the gene-environment interactions concept, the mechanism of health impairment can be explained by genetic factors, environmental factors, or their interaction. Physical and mental health effects resulting from environmental exposure may be classified either as toxicity, immune response, and allergic reaction. Moreover, despite the already established therapeutic approaches to bronchial asthma and decreasing mortality due to bronchial asthma, patients with difficult and severe asthma are increasing in number.

Background: Since it is difficult for expert endoscopists to diagnose early gastric cancer in post-eradication status, it may be critical to evaluate the stratification of high-risk groups using the advance of gastric atrophy or intestinal metaplasia. We tried to determine whether the combination of endoscopic artificial intelligence (AI) diagnosis for the evaluation of gastric atrophy could be a useful tool in both pre- and post-eradication status.

Methods: 270 -positive outpatients (Study I) were enrolled and Study II was planned to compare patients ( = 72) with pre-eradication therapy with post-eradication therapy.

The artery of Percheron (AOP), a common anatomic vascular variation of the P1 segment of the posterior cerebral artery, provides arterial blood supply to the paramedian thalami and rostral midbrain. Occlusion of the AOP can lead to infarction of the bilateral paramedian thalamus, with or without midbrain involvement, but is rare in children. Here, we describe a case involving a 14-year-old girl with sudden onset of disturbance of consciousness, hypersomnia, and global aphasia.
