Electrical storm in a patient with Charcot-Marie-Tooth disease treated with radiofrequency ablation and subsequent serious complication of implantable cardioverter defibrillator implantation: a case report.
Eur Heart J Case Rep

Background: Charcot-Marie-Tooth is the most common inherited neuromuscular disorder. Rarely, it can be associated with heart failure and various arrhythmic disturbances. This case illustrates the challenges of making decisions to prevent sudden cardiac death in a patient with Charcot-Marie-Tooth disease.

Catheter ablation-based management strategies for the drug-refractory electrical storm (ES) have been proven to abolish acute ventricular arrhythmic episodes and improve long-term outcomes. However, this effect is highly influenced by multiple independently acting factors, which, if identified and addressed, may allow a more tailored management to each particular case to improve results. This review synthesizes existing evidence concerning ES outcome predictors of patients undergoing ablation and introduces the role of novel scoring algorithms to refine risk stratification.

The overexpression of glutathione (GSH) within the tumor microenvironment has long been considered as the major obstacle for reactive oxygen species (ROS)-based antitumor therapies. To address this challenge, a selenite (SeO) and ferric ion co-doped hydroxyapatite (SF-HAP) nanohybrid was synthesized, which is then introduced into poly-L-lactic acid (PLLA) to prepare porous scaffold by selective laser sintering to continuously release Fe and SeO ions. Of great significance is the released SeO catabolize GSH to generate superoxide anion (O) rather than directly eliminating GSH, thereby reversing the obstacle posed by its overexpression and achieving a "waste-to-treasure" transformation.

Background: Ventricular arrhythmia is a common type of arrhythmia observed in clinical practice. It is primarily characterized by premature ventricular contractions, ventricular tachycardia, and ventricular fibrillation. Abnormal formation or transmission of cardiac electrical impulses in patients affects cardiac ejection function.

Background: Identifying spontaneous circulation during cardiopulmonary resuscitation (CPR) is challenging. Current methods, which involve intermittent and time-consuming pulse checks, necessitate pauses in chest compressions. This issue is problematic in both in-hospital cardiac arrest and out-of-hospital cardiac arrest situations, where resources for identifying circulation during CPR may be limited.
