Vascular calcification is established to be a critical factor in diabetes mellitus, which causes cardiovascular and amputation complication of diabetic patients. OPG/RANKL/RANK axis serves as a regulatory role in vascular calcification. Ghrelin, an endogenous ligand of growth hormone secretagogue receptor (GHSR), has been reported to exhibit potent cardiovascular protective effects. However, the role of ghrelin in the regulation of diabetic vascular calcification is still elusive. Here, we reported the role of ghrelin and its relationship with OPG/RANKL/RANK system in patients with diabetic foot amputation...

PURPOSE: Hemodialysis patients have extremely increased cardiovascular mortality. The coronary artery calcification score (CACS) in uremic patients receiving hemodialysis reflects the severity of atherosclerotic vascular disease and predicts the cardiovascular events. In cardiac conditions, left atrial (LA) size has a prognostic importance. In this study, relationship between coronary artery calcification and left atrial size was investigated. METHODS: This was a cross-sectional study involving 32 hemodialysis patients (16 females, 16 males; mean age, 52...

OBJECTIVE: Cardiovascular diseases constitute the leading cause of mortality worldwide. Calcification of the vessel wall is associated with cardiovascular morbidity and mortality in patients having many diseases, including diabetes mellitus, atherosclerosis, and chronic kidney disease. Vascular calcification is actively regulated by inductive and inhibitory mechanisms (including vascular smooth muscle cell adaptation) and results from an active osteogenic process. During the calcification process, extracellular vesicles (also known as matrix vesicles) released by vascular smooth muscle cells interact with type I collagen and then act as nucleating foci for calcium crystallization...

BACKGROUND: Emerging evidences have indicated that long non-coding RNAs (lncRNAs) play vital roles in cardiovascular physiology and pathology. The lncRNA MALAT1, a highly abundant and conserved imprinted gene, has been implicated in many cardiovascular diseases. However, the function of MALAT1 in calcific aortic valve disease (CAVD) remains unknown. This study sought to document the function and underlying mechanism of MALAT1 in regulating CAVD. METHODS: Protein level was determined by immunoblotting and immunofluorescence staining...

BACKGROUND AND AIMS: Women with systemic lupus erythematosus (SLE) have an increased risk of cardiovascular disease (CVD). Perivascular adipose tissue (PVAT) surrounds the vascular wall, is associated with CVD risk factors, and may contribute to premature CVD in SLE. We previously found greater volumes of aortic PVAT associated with aortic calcification (AC) in female SLE patients. There is recent evidence that not only volume but adipose density may also be indicative of inflammation...

Cardiovascular disease is the main cause of early death in the settings of chronic kidney disease (CKD), type 2 diabetes mellitus (T2DM), and ageing. Cardiovascular events can be caused by an imbalance between promoters and inhibitors of mineralization, which leads to vascular calcification. This process is akin to skeletal mineralization, which is carefully regulated and in which isozymes of alkaline phosphatase (ALP) have a crucial role. Four genes encode ALP isozymes in humans. Intestinal, placental and germ cell ALPs are tissue-specific, whereas the tissue-nonspecific isozyme of ALP (TNALP) is present in several tissues, including bone, liver and kidney...

BACKGROUND AND AIMS: Although much has been written about the conventional cardiovascular risk factor correlates of the extent of coronary artery calcification (CAC), few studies have been carried out on symptomatic patients. This paper assesses the potential ability of risk factors to associate with an increasing CAC score. METHODS: From the European Calcific Coronary Artery Disease (Euro-CCAD) cohort, we retrospectively investigated 6309 symptomatic patients, 62% male, from Denmark, France, Germany, Italy, Spain and the USA...

Nonalcoholic fatty liver disease may range from simple steatosis to fibrosis and cirrhosis. It is associated with the development of coronary artery calcification and appears to be an independent predictor of future adverse cardiovascular events. As the presence of a fatty liver appears to portray an independent increased risk, it may be beneficial to note this on coronary artery calcium scoring reports. Determination of fatty liver is relatively easy to perform. We discuss the method used by the Multi-Ethnic Study of Atherosclerosis (MESA) study for determination of fatty liver from CT coronary artery calcium scoring acquisitions, which may be implemented in clinical analysis...

Calcific aortic valve disease (CAVD) is a major cardiovascular disorder caused by osteogenic differentiation of valvular interstitial cells (VICs) within aortic valves. Conventional methods like colorimetric assays and histology fail to detect small calcium depositions during in-vitro VIC cultures. Laser-induced breakdown spectroscopy (LIBS) is a robust analytical tool used for inorganic materials characterizations, but relatively new to biomedical applications. We employ LIBS, for the first time, for quantitative in-vitro detection of calcium depositions in VICs at various osteogenic differentiation stages...

Dominique P Germain
Pseudoxanthoma elasticum (PXE) is a genetic metabolic disease with autosomal recessive inheritance caused by mutations in the ABCC6 gene. The lack of functional ABCC6 protein leads to ectopic mineralization that is most apparent in the elastic tissues of the skin, eyes and blood vessels. The clinical prevalence of PXE has been estimated at between 1 per 100,000 and 1 per 25,000, with slight female predominance. The first clinical sign of PXE is almost always small yellow papules on the nape and sides of the neck and in flexural areas...

Background -Psoriasis, a chronic inflammatory disease associated with an accelerated risk of MI, provides an ideal human model to study inflammatory atherogenesis in vivo We hypothesized that the increased cardiovascular risk observed in psoriasis would be partially attributable to an elevated subclinical coronary artery disease (CAD) burden composed of non-calcified plaques with high-risk features. However, inadequate efforts have been made to directly measure CAD in this vulnerable population. As such, we sought to compare total (TB) and non-calcified (NCB) coronary plaque burden, and high-risk plaque (HRP) prevalence, between psoriasis patients (n=105), hyperlipidemic patients eligible for statin therapy under NCEP-ATP III guidelines (n=100) who were ~10 years older, and non-psoriasis healthy volunteers (HV) (n=25)...

BACKGROUND: Kidney recipients are increasingly older with arterial disease and extended arterial calcifications. In a kidney transplantation population, the prognosis value of aortic and iliac calcifications remains poorly explored. We aimed to assess the impact of pre-transplantation Aortoiliac vascular calcifications on patients, grafts survival and cardiovascular events. METHODS: This retrospective study included kidney transplantation patients from 2006 to 2012 for whom we had available pre-surgery abdominal computed tomography results (n=100)...

PURPOSE OF REVIEW: The kidneys play a critical role in the balance between the internal milieu and external environment. Kidney failure is known to disrupt a number of homeostatic mechanisms that control serum calcium and normal bone metabolism. However, our understanding of calcium balance throughout the stages of chronic kidney disease is limited and the concept of balance itself, especially with a cation as complex as calcium, is often misunderstood. Both negative and positive calcium balance have important implications in patients with chronic kidney disease, where negative balance may increase risk of osteoporosis and fracture and positive balance may increase risk of vascular calcification and cardiovascular events...

GOALS: Because of shared risk factors between clinically manifest cardiovascular disease and colorectal cancer, we hypothesized the coexistence of subclinical atherosclerosis measured by coronary artery calcium (CAC) and colorectal adenoma (CRA) and that these 2 processes would also share common risk factors. BACKGROUND: No study has directly compared the risk factors associated with subclinical coronary atherosclerosis and CRA. STUDY: This was a cross-sectional study using multinomial logistic regression analysis of 4859 adults who participated in a health screening examination (2010 to 2011; analysis 2014 to 2015)...

A series of clinical trials have confirmed the correlation between vascular calcification (VC) and cardiovascular events and mortality. However, current treatments have little effects on the regression of VC. Potent and illustrative mechanisms have been proven to exist in both bone metabolism and VC, indicating that these two processes share similarities in onset and progression. Multiple osteoblast-like cells and signaling pathways are involved in the process of VC. In this review, we summarized the roles of different osteoblast-like cells and we emphasized on how they communicated and interacted with each other using different signaling pathways...

Psoriasis is a multifactorial inflammatory disorder, in which the inflammation affects not only the skin but also the other internal organs, and can induce cardiovascular and cerebrovascular involvements. However, few predictive factors of cardiovascular diseases have been clarified in patients with psoriasis. This study was performed to verify whether diagonal earlobe creases (ELC) can reflect the hidden comorbidities in Japanese psoriatic patients. Prevalence and subtypes of ELC were analyzed in patients with psoriatic and with non-psoriatic skin diseases, and the correlation with coronary artery calcification (CAC) or fatty liver (FL) detected by computed tomography...
