The long QT syndrome

, 2014
The long QT syndrome (LQTS) is an arrhythmogenic syndrome due to cardiac ion channel disorders characterized by prolonged QT interval on ECG (QTc >440 ms for male, >460 ms for female) and the most common presentations are syncope, seizures, cardiac

Patients with cyclops syndrome exhibit elevated synovial fluid interleukin‐6 (IL‐6) and tumor necrosis factor alpha (TNF‐α) levels and disorganized collagen remodelling within the lesion: A histological and molecular study

Journal of Experimental Orthopaedics, Volume 13, Issue 4, October 2026.
A stepwise approach: from tissue biopsies to histological and molecular analysis. Abstract Purpose Cyclops syndrome is a clinically relevant complication of anterior cruciate ligament (ACL) reconstruction characterized by the formation of a fibrotic nodule (cyclops lesion) that causes extension loss and often requires a revision surgery.

Permanent Cardiac Pacing in Children: A 30‐Year Follow‐Up Retrospective Study in a Single Pediatric Asian Center

Journal of Arrhythmia, Volume 42, Issue 5, October 2026.
This 30‐year retrospective study of pediatric permanent pacing found acceptable long‐term device complication rates, with epicardial leads used predominantly. Pacing‐induced cardiomyopathy occurred only in children with congenital heart disease, highlighting the need for individualized pacing strategies in this cohort and long‐term echocardiographic ...

Do Stimulants Promote Arrhythmic Risk: Insights From a Human‐Induced Pluripotent Stem Cell‐Derived Cardiomyocyte Model

Journal of Arrhythmia, Volume 42, Issue 5, October 2026.
At clinically relevant plasma concentrations, stimulant medications produced minimal effects on conduction velocity but modulated automaticity and repolarization in a hiPSC‐derived cardiomyocyte (hiPSC‐CM) model. These findings provide a foundation for future investigations of stimulant‐associated cardiac safety and support the utility of hiPSC‐CM ...

Iron and Other Metal Ions in Human Health and Disease

MedComm, Volume 7, Issue 10, October 2026.
Iron, copper, zinc, and calcium orchestrate cellular function through distinct yet cooperative mechanisms: redox‐active iron and copper cycle between oxidation states to act as Fenton catalysts and electron carriers in oxidative phosphorylation (OXPHOS); redox‐inert zinc serves as a structural component of zinc‐finger proteins and a catalytic cofactor ...
