Article Synopsis
  • Inherited forms of arrhythmogenic and dilated cardiomyopathy (ACM and DCM) exhibit varying symptoms and risk levels depending on age, with calcium regulation being a key factor in these heart conditions.
  • A specific genetic change, c.286T>G p.(Ser96Ala), linked to serious arrhythmias in DCM patients, was examined for its impact on different cardiomyopathy groups, including those with a known pathogenic variant.
  • The study found no significant differences in allele frequency between the general population and those with cardiomyopathy, indicating the p.(Ser96Ala) polymorphism does not modify disease severity or risk, suggesting the need for further research into reliable genetic markers for these heart conditions

J Am Coll Cardiol

November 2023

Department of Cardiology, University Medical Center Groningen, University of Groningen, Groningen, the Netherlands.

Article Synopsis
  • Major advances in heart failure treatment haven't significantly reduced mortality, indicating that current therapies might be missing key biological pathways.
  • A study integrated genetic and molecular data from over 2,500 heart failure patients to identify critical pathways linked to mortality, validating the results with a separate group of nearly 1,800 patients.
  • Four major pathways associated with higher death rates were found: PI3K/Akt, MAPK, Ras signaling, and resistance to epidermal growth factor inhibitor, which are linked to reduced activation of the protective ERBB2 receptor influenced by neuregulin.

Unlabelled: Current morphologic features defining advanced adenomas (size ≥10 mm, high-grade dysplasia or ≥25% villous component) cannot optimally distinguish individuals at high risk or low risk of metachronous colorectal cancer (me-CRC), which may result in suboptimal surveillance. Certain DNA copy-number alterations (CNAs) are associated with adenoma-to-carcinoma progression. We aimed to evaluate whether these molecular features can better predict an individual's risk of me-CRC than the morphologic advanced adenoma features.

Study Question: What is the influence of dietary interventions, namely the low fermentable oligo-, di-, mono-saccharides, and polyols (Low FODMAP) diet and endometriosis diet, on endometriosis-related pain and quality of life (QoL) compared to a control group?

Summary Answer: After adhering to a dietary intervention for 6 months, women with endometriosis reported less pain and an improved QoL compared to baseline whereas, compared to the control group, they reported less bloating and a better QoL in 3 of 11 domains.

What Is Known Already: Standard endometriosis treatment can be insufficient or may be accompanied by unacceptable side effects. This has resulted in an increasing interest in self-management strategies, including the appliance of the Low FODMAP diet and the endometriosis diet (an experience-based avoidance diet, developed by women with endometriosis).

25 years of basic and translational science in EP Europace: novel insights into arrhythmia mechanisms and therapeutic strategies.

Europace

August 2023

Translational Cardiology, Department of Cardiology and Department of Physiology, Inselspital University Hospital Bern, University of Bern, 3012 Bern, Switzerland.

In the last 25 years, EP Europace has published more than 300 basic and translational science articles covering different arrhythmia types (ranging from atrial fibrillation to ventricular tachyarrhythmias), different diseases predisposing to arrhythmia formation (such as genetic arrhythmia disorders and heart failure), and different interventional and pharmacological anti-arrhythmic treatment strategies (ranging from pacing and defibrillation to different ablation approaches and novel drug-therapies). These studies have been conducted in cellular models, small and large animal models, and in the last couple of years increasingly in silico using computational approaches. In sum, these articles have contributed substantially to our pathophysiological understanding of arrhythmia mechanisms and treatment options; many of which have made their way into clinical applications.
