Calcification-related chronic inflammatory diseases are multifactorial pathological processes, involving a complex interplay between inflammation and calcification events in a positive feed-back loop driving disease progression. Gla-rich protein (GRP) is a vitamin K dependent protein (VKDP) shown to function as a calcification inhibitor in cardiovascular and articular tissues, and proposed as an anti-inflammatory agent in chondrocytes and synoviocytes, acting as a new crosstalk factor between these two interconnected events in osteoarthritis...

Hyperhomocysteinemia has attracted a lot of attention in renal patients, not only because of its close relationship with renal function but also because it has been implicated as an independent cardiovascular risk factor in these patients. An increased level of C-reactive protein (CRP) has been reported to be a strong predictor of cardiovascular mortality in hemodialysis (HD) patients. The aim of this study was to assess the association between homocysteine (Hcy) and highly sensitive CRP (hsCRP) in cardiovascular risk prediction in children with chronic kidney disease (CKD) on HD...

Vascular calcification (VC) is common among patients with chronic kidney disease (CKD). The severity of VC is associated with increased risk of cardiovascular events and mortality. Risk factors for VC include traditional cardiovascular risk factors as well as CKD-related risk factors such as increased calcium and phosphate load. VC is observed in arteries of all sizes from small arterioles to aorta, both in the intima and the media of arterial wall. Several imaging techniques have been utilized in the evaluation of the extent and the severity of VC...

We assessed the relationships among adult height, coronary artery calcium (CAC) scores, incident atherosclerotic cardiovascular disease (ASCVD) events, and atrial fibrillation (Afib) in a multi-ethnic cohort. We used race/ethnicity -specific height (dichotomized by median and quartiles) as the predictor variable within the four race/ethnic groups in the Multi-Ethnic Study of Atherosclerosis (N = 6,814). After a mean of 10.2 years of follow-up (2000-2012), 556 ASCVD events (8.2%) and 539 afib events (7.9%) occurred...

Arterial hypertension and chronic kidney disease (CKD) are intimately related. The control of blood pressure (BP) levels is strongly recommended in patients with CKD in order to protect the kidney against the accompanying elevation in global cardiovascular (CV) risk. Actually, the goal BP in patients with CKD involves attaining values <140/90 mmHg except if albuminuria is present. In this case, it is often recommended to attain values <130/80 mmHg, although some guidelines still recommend <140/90 mmHg...

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: Cigarette smoking plays a major role in cardiovascular diseases. The acute effects of cigarette smoking produce central nervous system-mediated activation of the sympathetic nervous system. The overactive sympathetic nervous system stimulates the secretion of serotonin (5-HT) and catecholamine into blood at supraphysiological levels. The correlation between these pathological conditions induced by smoking and the increased risk of thrombosis has not been thoroughly investigated...

Aims: Beyond the control of nuclear-cytoplasmic trafficking nucleoporins regulate gene expression and are involved in cardiac diseases. Notably, a number of cardiovascular disorders have been linked to alterations in epigenetic mechanisms. Here we aimed to determine the contribution of Nup153 to the epigenetic alterations occurring in cardiomyopathy of dystrophin-deficient mdx mice (C57BL/10ScSn-Dmd mdx /J). Methods and results: Nup153 was lysine-acetylated and its expression was significantly increased at protein level in mdx hearts compared with controls...

OBJECTIVE: Use of antihypertensive medication (AHM) is potentially associated with a reduced risk of dementia. Both calcium channel blockers (CCBs) and angiotensin receptor blockers (ARBs) are suggested to have a more pronounced protective effect. We aimed to study the association between different classes of AHM and dementia in older people. METHODS: A subgroup of community-dwelling older people using AHM included in the 'Prevention of Dementia by Intensive Vascular Care' randomized controlled trial was studied...

Diabetes mellitus is associated with an increased risk for cardiovascular disease, but the link between hyperglycemia and atherothrombotic disease is not completely understood. Patients with diabetes often show hyporesponsiveness to antiplatelet therapies, and it has been suggested that hyperreactive reticulated platelets underlie this altered therapeutic response. In this issue of the JCI, Kraakman et al. uncover a previously unknown link between hyperglycemia and enhanced platelet production and reactivity...

Platelets play a critical role in atherogenesis and thrombosis-mediated myocardial ischemia, processes that are accelerated in diabetes. Whether hyperglycemia promotes platelet production and whether enhanced platelet production contributes to enhanced atherothrombosis remains unknown. Here we found that in response to hyperglycemia, neutrophil-derived S100 calcium-binding proteins A8/A9 (S100A8/A9) interact with the receptor for advanced glycation end products (RAGE) on hepatic Kupffer cells, resulting in increased production of IL-6, a pleiotropic cytokine that is implicated in inflammatory thrombocytosis...

In an important new cross-sectional analysis in this issue, Graciolli and colleagues present bone data from 148 adult patients across the spectrum of chronic kidney disease that confirm that disrupted osteocyte function and abnormal bone histology characterize all stages of chronic kidney disease and suggest that osteocytic Wnt signaling and osteocyte maturation may play a role in the pathogenesis of renal osteodystrophy. These concepts may alter how the skeletal, cardiovascular, and infectious complications of chronic kidney disease are managed...
