Oxytocin exerts harmful cardiac repolarization prolonging effects in drug-induced LQTS

International Journal of Cardiology: Heart & Vasculature, 2022
Background: Oxytocin is used therapeutically in psychiatric patients. Many of these also receive anti-depressant or anti-psychotic drugs causing acquired long-QT-syndrome (LQTS) by blocking HERG/IKr.

Network medicine and systems pharmacology approaches to predicting adverse drug effects

British Journal of Pharmacology, EarlyView.
Identifying and understanding the relationships between drug intake and adverse effects that can occur due to inadvertent molecular interactions between drugs and targets is a difficult task, especially considering the numerous variables that can influence the onset of such events.

Methods of Assessment and Clinical Relevance of QT Dynamics [PDF]

, 2005
The dependence on heart rate of the QT interval has been investigated for many years and several mathematical formulae have been proposed to describe the QT interval/heart rate (or QT interval/RR interval) relationship. While the most popular is Bazett’s

Older Age Is Associated With Long‐Term Retention in Buprenorphine Treatment for Opioid Use Disorder

Journal of the American Geriatrics Society, EarlyView.
ABSTRACT Background Opioid use disorder (OUD) among older adults is a fast‐growing public health problem. However, little is known about treatment outcomes among older adults in office‐based buprenorphine programs. Thus, our objective was to examine how age is associated with buprenorphine treatment outcomes among adults with OUD who initiate ...

Characterisation of sleep apneas and respiratory circuitry in mice lacking CDKL5

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary CDKL5 deficiency disorder is a rare genetic disease caused by mutations in the CDKL5 gene. Central apneas during wakefulness have been reported in patients with CDKL5 deficiency disorder. Studies on CDKL5‐knockout mice, a CDKL5 deficiency disorder model, reported sleep apneas, but it is still unclear whether these events are central (central ...

Anthracyclines and Acquired Long QT Syndrome. A Case Report

Revista Finlay, 2014
Acquired long QT syndrome results from secondary causes and can be caused by more than 100 non-antiarrhythmic drugs. Cardiac arrest due to Torsades de pointes induced by drugs causing prolonged QT syndrome is a rare but potentially fatal event, even in ...

Cardiac‐specific Kv1.1 deficiency alters cardiomyocyte electrophysiology without modifying overall cardiac function or arrhythmia susceptibility

Experimental Physiology, EarlyView.
Abstract The leading cause of epilepsy‐related mortality is sudden unexpected death in epilepsy (SUDEP), resulting from seizure‐induced cardiorespiratory arrest by mechanisms that remain unresolved. Mutations in ion channel genes expressed in both brain and heart represent SUDEP risk factors because they can disrupt neural and cardiac rhythms ...

Cardiac remodelling in type 2 diabetes: Pathophysiological mechanisms and opportunities for multiscale computational modelling and simulation

The Journal of Physiology, EarlyView.
Abstract figure legend Overview of multiscale cardiac remodelling in type 2 diabetes and how to model and simulate these changes using a human‐based, multiscale computational framework. Cardiac remodelling in type 2 diabetes occurs at ionic channel, protein, cellular, tissue and whole‐organ level, affecting the electrophysiological function, mechanical

Sleep-Associated Torsades de Pointes: A Case Report

Clinical Practice and Cases in Emergency Medicine, 2017
Torsades de Pointes (TdP) is a polymorphic ventricular tachycardia that occurs in the presence of an acquired or congenital long QT syndrome (LQTS). We present the case of a 57 year-old man with end-stage renal disease on methadone maintenance in which ...

Ion channels: structural basis for function and disease. [PDF]

, 1996
Ion channels are ubiquitous proteins that mediate nervous and muscular function, rapid transmembrane signaling events, and ionic and fluid balance. The cloning of genes encoding ion channels has led to major strides in understanding the mechanistic basis
