To perform a comprehensive phenotype-genotype correlation of all rare variants in Triadin leading to malignant arrhythmias in pediatrics. Triadin knockout syndrome is a rare entity reported in pediatric population. This syndrome is caused by rare variants in the gene. Malignant ventricular arrhythmias and sudden cardiac death can be a primary manifestation of disease. Although pharmacological measures are effective, some patients require an implantable defibrillator due to high risk of arrhythmogenic episodes. Fourteen rare genetic alterations in have been reported to date. All of these potentially pathogenic alterations are located in a specific area of , highlighting this hot spot as an arrhythmogenic gene region. Early recognition and comprehensive interpretation of alterations in Triadin are crucial to adopt preventive measures and avoid malignant arrhythmogenic episodes in pediatric population.

Financial burden of complications following lung resection: a scoping review protocol.

BMJ Open

Department of Anaesthesia, Austin Health, Heidelberg, Victoria, Australia

Introduction: Global healthcare expenditures are rising, driven largely by increased spending in both high- and low-income countries with hospitalisation as a primary contributor. Respiratory diseases, particularly lung cancer, pose significant public health and economic challenges with thoracic surgery as the standard curative treatment. Complications post resection, such as arrhythmias, infections and respiratory failure, result in substantial healthcare costs and resource demands.

Locoregional anesthesia in patients with Brugada syndrome. A retrospective database analysis.

Acta Anaesthesiol Scand

February 2025

Department of Anesthesiology and perioperative medicine, University Hospital of Brussels, Free University of Brussels, Brussels, Belgium.

Background: The use of local anesthetics (LA) in individuals with Brugada syndrome (BrS) remains a subject of debate due to the lack of large-scale studies confirming their potential risks. This study primarily aimed to evaluate the incidence of new malignant arrhythmias or defibrillation events in patients diagnosed with BrS during the perioperative period, following the administration of local anesthetics, and within 30 days postoperatively. The secondary objective was to analyze the occurrence of adverse effects during hospitalization, as well as 30-day readmission and mortality rates.

Objective: The study aimed to define atrial fibrillation frequency in endometrial cancer patients, identify risk factors, and propose preventive steps for early detection and treatment leading to decreasing cardiovascular risk. Secondly, we aimed to highlight this topic by presenting a systematic literature review.

Methodology: Retrospective analysis of endometrial cancer patients treated at the Department of Gynecology and Obstetrics at University Hospital Brno between 2006 and 2023 complemented by a systematic literature review.

Mesenchymal stem cells (MSCs) are a class of protocells that can differentiate into various cell types and have robust replication and renewal capabilities. MSCs secrete various nutritional factors to regulate the microenvironment of tumor tissues. The mechanism by which they inhibit or promote tumor growth may be closely related to MSC-derived exosomes (MSC-Exo).
