Assessment of cardiac iron deposition and genotypic classification in pediatric beta-thalassemia major: the role of cardiac MRI.

Department of Radiology, Shenzhen Children's Hospital, Shantou University Medical College, 7019 Yitian Road, Futian District, Shenzhen, 518038, China.
Background: Beta thalassemia major (β-TM) is a severe genetic anemia with considerable phenotypic heterogeneity. This study investigated whether genotype correlates with distinct myocardial iron overload patterns, assessed by cardiovascular magnetic resonance (CMR) T2* values.
Methods: CMR data for cardiac iron deposition evaluation, which recruited pediatric participants between January 2021 and December 2024, were analyzed with CVI42.

Pediatric non-alcoholic fatty liver disease (NAFLD) is emerging as a worldwide health concern with the potential to advance to cirrhosis and liver cancer. NAFLD can also directly contribute to heart problems through inflammation and insulin resistance, even in individuals without other risk factors. The pathological mechanisms of NAFLD are linked to functional differences of miRNAs in different biological environments.

The aim of this study was to evaluate the subclinical patterns and evolution of cardiac abnormalities via transthoracic echocardiography (TTE) in patients with mild initial COVID-19 illness. A total of 343 infected individuals (163 males; age 44 (interquartile range, IQR 35-52) years) years) underwent serial TTE assessments at a median of 109 (interquartile range (IQR), 77-177) and 327 (276-379) days after infection. Compared with those of non-COVID-19-infected controls (n = 94, male n = 49), baseline systolic (LVEF, TAPSE) and diastolic function (e', a', E/e') were significantly different in infected participants (p < 0.

Purpose: Residual neuromuscular blockade can impair postoperative respiratory mechanics, promoting hypoxemia and pulmonary complications. Sugammadex, with its unique mechanism of action, may offer a more effective reversal of neuromuscular blockade and respiratory function than neostigmine. We sought to test the primary hypothesis that children undergoing noncardiac surgery exhibit better initial recovery oxygenation when administered sugammadex than those administered neostigmine.

Pathological left ventricular remodeling is a complex process following an acute myocardial infarction, leading to architectural disorganization of the cardiac tissue. This phenomenon is characterized by sterile inflammation and the exaggerated development of fibrotic tissue, which is non-contractile and poorly conductive, responsible for organ dysfunction and heart failure. At present, specific therapies are lacking for both prevention and treatment of this condition, and no biomarkers are currently validated to identify at-risk patients.
