Cardiovascular disease (CVD) is a major global health challenge, and its co-occurrence with diabetes mellitus (DM) contributes significantly to morbidity and mortality. Yemen, a nation facing unique healthcare complexities, necessitates an in-depth investigation into the prevalence of cardiovascular risk (CVR) factors among its population with DM. This systematic review and meta-analysis aimed to determine the prevalence of CVR factors among individuals with diabetes in Yemen, to understand and highlight the knowledge gap, and to influence targeted interventions and policies.

Article Synopsis
  • Coronary computed tomography angiography (CCTA) was evaluated as an alternative to intravascular imaging techniques for assessing plaque pathology in patients with chronic coronary syndrome.
  • The study involved 70 patients and compared CCTA with near-infrared spectroscopy-intravascular ultrasound (NIRS-IVUS) to analyze atheroma burden and composition, focusing on the accuracy of detecting lipid-rich plaques.
  • Results showed that CCTA had limitations in accurately measuring plaque dimensions and composition, leading to potential issues in planning for coronary interventions.

Dynamic protein phosphorylation and dephosphorylation play an essential role in cell cycle progression. Kinases and phosphatases are generally highly conserved across eukaryotes, underlining their importance for post-translational regulation of substrate proteins. In recent years, advances in phospho-proteomics have shed light on protein phosphorylation dynamics throughout the cell cycle, and ongoing progress in bioinformatics has significantly improved annotation of specific phosphorylation events to a given kinase.

Background: Among inherited cardiomyopathies involving the left ventricle, whether dilated or not, certain genotypes carry a well-established arrhythmic risk, notably manifested as sustained monomorphic ventricular tachycardia (SMVT). Nonetheless, the precise localization and electrophysiological profile of this substrate remain undisclosed across different genotypes.

Methods: Patients diagnosed with cardiomyopathy and left ventricle involvement due to high-risk genetic variants and SMVT treated by electrophysiological study were recruited from 18 European/US centers.

Cardiac magnetic resonance markers of pre-clinical hypertrophic and dilated cardiomyopathy in genetic variant carriers.

medRxiv

November 2024

Department of Cardiology, Amsterdam Cardiovascular Sciences, Amsterdam University Medical Centre, University of Amsterdam, Amsterdam, The Netherlands.

Article Synopsis
  • The study focused on identifying imaging biomarkers for pre-clinical cardiomyopathy in healthy people with genetic variants linked to hypertrophic cardiomyopathy (HCM) or dilated cardiomyopathy (DCM).
  • Out of 40,169 participants, 13 cardiac magnetic resonance (CMR) measurements were found to be linked to atrial fibrillation (AF) and 15 with heart failure (HF), with specific measurements correlating differently with HCM and DCM genetic risk.
  • The findings suggest that certain CMR measurements, particularly from the right side of the heart, can indicate early changes in heart function in individuals with HCM genetic variants, while left ventricular measures relate to DCM genetic risks

Background: Congenital thrombotic thrombocytopenic purpura (cTTP) is an ultrarare microvascular disease caused by the deficiency of the metalloprotease ADAMTS13 (a disintegrin and metalloprotease with thrombospondin motifs 13). Approximately half of all cases remain undiagnosed until a triggering event in adulthood; therefore, the prevalence rates may be underestimated. The current standard of care is based on regular transfusions of fresh frozen plasma, which often lead to allergic reactions in patients.

Proteoglycans and their proteolytic fragments diffuse into biological fluids such as plasma, serum, urine, or synovial fluid, where they can be detected by antibodies or mass-spectrometry. Neopeptides generated by the proteolysis of proteoglycans are recognized by specific neoepitope antibodies and can act as a proxy for the activity of certain proteases. Proteoglycan and proteoglycan fragments can be potentially used as prognostic, diagnostic, or theragnostic biomarkers for several diseases characterized by dysregulated extracellular matrix remodeling such as osteoarthritis, rheumatoid arthritis, atherosclerosis, thoracic aortic aneurysms, central nervous system disorders, viral infections, and cancer.
