Structural insights into the regulation of RyR1 by S100A1.

Proc Natl Acad Sci U S A

July 2024

Department of Physiology and Cellular Biophysics, Center for Molecular Cardiology, Columbia University Vagelos College of Physicians and Surgeons, New York, NY 10032.

Article Synopsis
  • S100A1 is a small protein that helps control calcium levels in muscles, which is important for how they work.
  • Researchers studied how S100A1 attaches to a big calcium channel in muscle cells called the ryanodine receptor (RyR).
  • When calcium is present, S100A1 changes shape and sticks to RyR even more tightly, which could help scientists create new treatments for muscle diseases.

Impaired Intracellular Calcium Buffering Contributes to the Arrhythmogenic Substrate in Atrial Myocytes From Patients With Atrial Fibrillation.

Circulation

August 2024

Cluster of Excellence "Multiscale Bioimaging: From Molecular Machines to Networks of Excitable Cells" (F.E.F., A.L., F.S., F.H., S.E.L., A.E., N.V.), Georg-August-University Göttingen, Germany.

Background: Alterations in the buffering of intracellular Ca, for which myofilament proteins play a key role, have been shown to promote cardiac arrhythmia. It is interesting that although studies report atrial myofibrillar degradation in patients with persistent atrial fibrillation (persAF), the intracellular Ca buffering profile in persAF remains obscure. Therefore, we aimed to investigate the intracellular buffering of Ca and its potential arrhythmogenic role in persAF.

Background:  The increasing presence of female doctors in the field of cardiac surgery has raised questions about their surgical quality compared to their male colleagues. Despite their success, female surgeons are still underrepresented in leadership positions, and biases and concerns regarding their performance persist. This study aims to examine whether female surgeons perform worse, equally well, or better than their male counterparts in commonly performed procedures that have a significant number of female patients.

Cluster analysis of volatile organic compounds - A pilot study in patients with severe acute decompensated heart failure.

J Cardiol

August 2024

Department of Cardiology, University Hospital Heart Center Brandenburg, Brandenburg Medical School (MHB) Theodor Fontane, Neuruppin, Germany; Faculty of Health Sciences Brandenburg, Neuruppin, Germany. Electronic address:

Introduction: Acute decompensated heart failure (ADHF) is a global health problem and early detection of high-risk patients for effective treatment is important. Exhaled breath analysis and measurement of volatile organic compounds (VOCs) may be a fast and cost-effective non-invasive diagnostic and screening tool complementing measurement of cardiac biomarkers. Another technique to detect and characterize VOCs is the ion mobility spectrometry (IMS) not requiring vacuum or sample pretreatment.

Background: Atrial fibrillation (AF) is a cardiac arrhythmia frequently documented in patients requiring implantable cardioverter defibrillators (ICDs) and/or cardiac resynchronization therapy with defibrillator (CRT-D). Patients with diagnosed AF at the point of ICD or CRT-D implantation may have an impaired follow-up outcome.

Methods: The German DEVICE I-II registry is a nationwide prospective multicentre database of patients implanted with ICD and CRT-D with clinical follow-up data.

Prior to the curative resection of colorectal carcinoma (CRC) or pancreatic ductal adenocarcinoma (PDAC), the exclusion of hepatic metastasis using cross-sectional imaging is mandatory. The Doppler perfusion index (DPI) of the liver is a promising method for detecting occult liver metastases, but the underlying visceral duplex sonography is critically viewed in terms of its reproducibility. The aim of this study was to investigate systematically the reproducibility of the measured variables, the calculated blood flow, and the DPI.

Aims: This study aims to assess the applicability of the mitral regurgitation (MR) proportionality concept in patients with atrial functional mitral regurgitation (aFMR) treated with transcatheter edge-to-edge repair (M-TEER). We hypothesized that patients with disproportionate MR (higher MR relative to left ventricular size) would exhibit different outcomes compared to those with proportionate MR, despite undergoing M-TEER.

Methods And Results: We retrospectively analysed 98 patients with aFMR from the EuroSMR registry who underwent M-TEER between 2008 and 2019.

Aims: Recent trial data demonstrate beneficial effects of active rhythm management in patients with atrial fibrillation (AF) and support the concept that a low arrhythmia burden is associated with a low risk of AF-related complications. The aim of this document is to summarize the key outcomes of the 9th AFNET/EHRA Consensus Conference of the Atrial Fibrillation NETwork (AFNET) and the European Heart Rhythm Association (EHRA).

Methods And Results: Eighty-three international experts met in Münster for 2 days in September 2023.

Introduction: Left atrial (LA) low voltage areas (LVA) are a controversial target in atrial fibrillation ablation procedures. However, LVA and LA volume are good predictors of arrhythmia recurrence in ablation-naïve patients. Their predictive value in progressively diseased pre-ablated atria is uncertain.

Front Cardiovasc Med

March 2024

Department for Angiology, Center for Internal Medicine I, Deutsches Angiologie Zentrum (DAZB), University Clinic Brandenburg, Brandenburg Medical School (MHB) Theodor Fontane, Brandenburg/Havel, Germany.

Article Synopsis
  • The study focused on a non-metropolitan region in Brandenburg, Germany, where there is a notable lack of awareness about lipoprotein(a) [Lp(a)] as a cardiovascular risk factor, particularly in a population with high rates of cardiovascular diseases and limited medical resources.
  • In a cohort of 850 participants, including 533 high cardiovascular risk patients and 317 healthy controls, Lp(a) levels were analyzed along with other cardiovascular health indicators to understand its impact on conditions like atherosclerotic cardiovascular disease (ASCVD).
  • Findings revealed that patients with cardiovascular diseases had significantly higher Lp(a) levels compared to healthy individuals, establishing Lp(a) as an independent risk factor for ASCVD, with higher rates of

3D Super-Resolution Nuclear Q-FISH Imaging Reveals Cell-Cycle-Related Telomere Changes.

Int J Mol Sci

March 2024

Department of Cardiology and Pneumology, Heart Research Center Göttingen, University Medical Center Göttingen, Robert-Koch-Str. 42a, 37075 Göttingen, Germany.

We present novel workflows for Q-FISH nanoscopy with the potential for prognostic applications and resolving novel chromatin compaction changes. DNA-fluorescence in situ hybridization (DNA-FISH) is a routine application to visualize telomeres, repetitive terminal DNA sequences, in cells and tissues. Telomere attrition is associated with inherited and acquired diseases, including cancer and cardiomyopathies, and is frequently analyzed by quantitative (Q)-FISH microscopy.

This is the third paper in the series providing updated information and recommendations for people with cystic fibrosis transmembrane conductance regulator (CFTR)-related disorder (CFTR-RD). This paper covers the individual disorders, including the established conditions - congenital absence of the vas deferens (CAVD), diffuse bronchiectasis and chronic or acute recurrent pancreatitis - and also other conditions which might be considered a CFTR-RD, including allergic bronchopulmonary aspergillosis, chronic rhinosinusitis, primary sclerosing cholangitis and aquagenic wrinkling. The CFTR functional and genetic evidence in support of the condition being a CFTR-RD are discussed and guidance for reaching the diagnosis, including alternative conditions to consider and management recommendations, is provided.

Idiopathic inflammatory myopathies are a group of rare, autoimmune, diseases typically involving striate muscle and also variously affecting several other systems or organs, such as joints, skin, lungs, heart and gastrointestinal tract. IIM are mainly characterised by subacute onset and chronic course and are burdened by significant morbidity and mortality. Despite the rarity of these conditions, several efforts have been undertaken in the last years to better understand their pathogenesis, as well as to achieve a more precise classification and to define the optimal therapeutic approach.
