AI Article Synopsis
- Vascular calcification in chronic kidney disease (CKD) is an active process influenced by cell death mechanisms.
- Apoptosis of vascular smooth muscle cells leads to the release of bodies that help calcium crystals form and deposit.
- Recent research by Ye et al. reveals that ferroptosis, another type of cell death, also plays a role in vascular calcification in CKD.
Article Abstract
Vascular calcification associated with chronic kidney disease (CKD) is an active, regulated process. Apoptosis of vascular smooth muscle cells has long been known to play a major role in its pathogenesis, with apoptotic bodies derived from these cells acting as nucleating structures for calcium crystal formation and deposition. Ye et al. now show in experimental models in vitro and in vivo that ferroptosis can also contribute to the development of vascular calcification in CKD.

Autosomal recessive hypophosphatemic rickets type 2 (ARHR2) is an uncommon hereditary form of rickets characterised by chronic renal phosphate loss and impaired bone mineralisation. This results from compound heterozygous or homozygous pathogenic variants in ectonucleotide pyrophosphatase/phosphodiesterase 1 (ENPP1), a key producer of extracellular inorganic pyrophosphate (PPi) and an inhibitor of fibroblast growth factor23 (FGF23). ENPP1 deficiency impacts FGF23 and increases its activity.

Background: In humans, larger artery stiffening is associated with increased tau phosphorylation and neurodegeneration. However, because arterial stiffness often co-occurs with other age-related conditions like hypertension, atherosclerosis, and diabetes, it is nearly impossible to distill the underlying mechanisms specifically linking arterial stiffening to abnormal brain function. We leveraged a surgical mouse model of larger artery stiffening and used it concurrently with a transgenic Alzheimer's disease (AD) mouse model of tau pathology to investigate the impact of larger artery stiffening on cognition.

Vertebral fracture assessment (VFA) images from bone density machines enable the automated machine learning assessment of abdominal aortic calcification (ML-AAC), a marker of cardiovascular disease (CVD) risk. The objective of this study was to describe the risk of a major adverse cardiovascular event (MACE, from linked health records) in patients attending routine bone mineral density (BMD) testing and meeting specific criteria based on age, BMD, height loss, or glucocorticoid use have a VFA in the Manitoba Bone Mineral Density Registry. The cohort included 10 250 individuals (mean 75.

Background: Mitral annular calcification (MAC) is characterized by severe calcification of mitral annulus and might be associated with both mitral regurgitation and stenosis. It is technically challenging for both surgical and percutaneous approach and is burdened by high mortality.
Case Summary: The present case report describes a complex case of mitral steno-insufficiency (baseline transvalvular gradient = 5 mmHg, effective regurgitant orifice area 0.
