Background: Immunometabolism is a crucial determinant of immune cell function, influencing cellular activation and differentiation through metabolic pathways. The intricate interplay between metabolism and immune responses is highlighted by the distinct metabolic programs utilized by immune cells to support their functions. Of particular interest is the pentose phosphate pathway (PPP), a key metabolic pathway branching out of glycolysis that plays a pivotal role in generating NADPH and pentose sugars crucial for antioxidant defense and biosynthesis.

Electronic address:

Although calcification in the cardiovascular system is highly studied, the mechanisms behind it are not well understood. Current proposed mechanisms focus on cellular processes leading to, or controlling the unwanted mineralization in soft tissues. However, extracellular components such as collagen and elastin fundamentally regulate the mechanical properties of heart tissues.

Zebrafish model for functional screening of flow-responsive genes controlling endothelial cell proliferation.

Sci Rep

December 2024

Biochemical Pharmacology,William Harvey Research Institute, Barts & The London Faculty of Medicine &Dentistry, Queen Mary University of London, Charterhouse Square, London, EC1M 6BQ, UK.

Local haemodynamics control arterial homeostasis and dysfunction by generating wall shear stress (WSS) which regulates endothelial cell (EC) physiology. Here we use a zebrafish model to identify genes that regulate EC proliferation in response to flow. Suppression of blood flow in zebrafish embryos (by targeting cardiac troponin) reduced EC proliferation in the intersegmental vessels (ISVs) compared to controls exposed to flow.

Department of Cardiology, Amsterdam UMC Location University of Amsterdam, Heart Center, Amsterdam Cardiovascular Sciences Heart failure and Arrhythmias, the Netherlands (L.R.A.O.N., S.P., L.V.A.B., T.F.B., A.-F.B.E.Q., W.v.d.S., L.S., J.A.d.V., J.G.P.T., N.R.B., J.R.d.G., K.M.K., A.d.W., A.A.M.W., R.E.K.).

Article Synopsis
  • Inappropriate therapy (IAT) is a significant issue associated with implantable cardiac defibrillator (ICD) therapy, particularly highlighted in early subcutaneous ICD (S-ICD) studies which showed high rates of inappropriate shocks (IAS).
  • The PRAETORIAN trial, an international study with 849 patients, found no major differences in IAT and IAS rates between S-ICD and transvenous ICD (TV-ICD) groups, as both groups had similar cumulative incidences.
  • Key predictors for IAT varied between the two groups, with TV-ICD patients experiencing IAT mainly from supraventricular tachycardias, while S-ICD patients faced issues from cardiac oversensing

In February 2024, medical students in South Korea began submitting leave-of-absence requests in protest of a 65% increase in the number of medical school places in 2025. 14,000 medical students have boycotted classes and 12,000 doctors have resigned en masse. The 2024 Korean medical student collective action highlights the 'power' of medical students, the need for independent medical licensing bodies and the risks to the quality of medical education when places in medical schools are rapidly increased.

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.

Diagnostics (Basel)

November 2024

Division of Cardiology, Department of Internal Medicine, The Catholic University of Korea, Uijeongbu St. Mary's Hospital, Seoul 06591, Republic of Korea.

Article Synopsis
  • Flow-mediated dilation (FMD) is a noninvasive technique used to assess vascular endothelial function, which reflects the body's vascular health and responses to inflammation.
  • * FMD is typically performed using ultrasound on the brachial artery, making it more accessible compared to invasive procedures like optical coherence tomography and intravascular ultrasound.
  • * Although endothelial examination via FMD isn't currently recommended for cardiovascular prevention due to inconsistent standard values, it shows promise in predicting cardiovascular outcomes in future research.

This literature review critically examines the historical, current, and prospective dimensions of sternal wound reconstruction in the specific context of deep sternal wound infection (DSWI), aiming to enhance patient outcomes and optimise surgical techniques. Preventive measures, including prophylactic antibiotic administration and surgical site preparation, are crucial in reducing the incidence of DSWI. Effective management necessitates a multidisciplinary approach encompassing surgical debridement, drainage, and sternum repair utilising diverse procedures in conjunction with antibiotic therapy.
