Outcomes of Subcutaneous Implantable Cardioverter Defibrillators in Patients Being Considered for Heart Transplantation: A Retrospective Cohort Study

Pacing and Clinical Electrophysiology, EarlyView.
Overview of the study cohort and principal findings. ABSTRACT Introduction Subcutaneous implantable cardioverter defibrillators (S‐ICD) are an alternative to transvenous devices (TV‐ICD) in patients not requiring bradycardia pacing, resynchronization (CRT) or anti‐tachycardia pacing (ATP).

Doxorubicin‐induced Cardiotoxicity in Dogs: A Narrative Review

Veterinary and Comparative Oncology, EarlyView.
ABSTRACT Doxorubicin, an anthracycline widely used in both human and veterinary oncology, is highly effective against a variety of malignancies in dogs, including lymphomas, sarcomas and carcinomas. Despite its efficacy, doxorubicin exposure can be associated with cardiotoxicity, which may present acutely or chronically, potentially leading to severe ...

Cellular mechanisms of radiation‐induced myocyte dysfunction: effects on calcium handling, ion channel regulation and mitochondrial energetics

The Journal of Physiology, EarlyView.
Abstract figure legend Dose‐dependent effects of radiation on cardiac electrophysiology and arrhythmia susceptibility. At low radiation doses (left), increased reactive oxygen species (ROS) initiate an ROS–Ca2+ positive feedback loop involving calcium/calmodulin‐dependent protein kinase II (CaMKII) activation, enhanced L‐type Ca2+ current (ICaL ...

Prevalence and Clinical Significance of QRS Fragmentation and Low QRS Voltages in Elite Female Football Players [PDF]

Aims: QRS fragmentation (fQRS) and low QRS voltage are electrocardiogram (ECG) findings associated with cardiomyopathy and adverse cardiac events. However, their prevalence and significance in elite female athletes are unknown.

Quantification of abnormal QRS peaks predicts response to cardiac resynchronization therapy and tracks structural remodeling.

PLoS ONE, 2019
BackgroundAlthough QRS duration (QRSd) is an important determinant of cardiac resynchronization therapy (CRT) response, non-responder rates remain high. QRS fragmentation can also reflect electrical dyssynchrony.

Antidepressant Misuse in Esports: A Review of Pharmacology, Adverse Effects, Pharmacokinetics and Biomatrix‐Based Detection for Anti‐Doping Applications

Drug Testing and Analysis, Volume 18, Issue 11, Page 1361-1373, November 2026.
This review highlights the misuse of antidepressants as potential cognitive‐enhancing agents in Esports. Despite pharmacological effects that overlap with those of psychostimulants, antidepressants remain an under‐recognised source of doping in Esports.

Clinical applications of wearable devices for individuals with at‐risk substance use and substance use disorders: A systematic review

The American Journal on Addictions, Volume 35, Issue 6, Page 702-726, November 2026.
Abstract Background and Objectives Managing substance use disorders (SUDs) is limited by the lack of longitudinal clinical data during active use and recovery. Wearable devices may help address this gap by capturing physiological and behavioral data in real‐world settings.
