Metabolic syndromes (MS) are a cluster of disorders like obesity, hypertension, dyslipidemia, and diabetes. Cardiometabolic syndrome (CMS), a branch of MS, is a group of diseases affecting cardiovascular, renal, metabolic, prothrombotic and inflammatory abnormalities due to defects in energy metabolism. Since the emergence of molecular biology and the discovery of pathogenic mitochondrial DNA defect in the 1980s, research advances has revealed a number of common human disease involving mitochondrial dysfunction...

Heart failure (HF) is a common cardiac syndrome, whose pathophysiology involves complex mechanisms, some of which remain unknown. Diabetes mellitus (DM) constitutes not only a glucose metabolic disorder accompanied by insulin resistance but also a risk factor for cardiovascular disease and HF. During the last years though emerging data set up, a bidirectional interrelationship between these two entities. In the case of DM impaired calcium homeostasis, free fatty acid metabolism, redox state, and advance glycation end products may accelerate cardiac dysfunction...

BACKGROUND: Increasing evidence exists regarding calcium detected in aortic cusps and/or mitral annulus (AOC_MAC) at transthoracic echocardiogram as a predictor of cardiovascular (CV) events and mortality. PURPOSE: To verify whether AOC_MAC has a prognostic role in the setting of primary prevention independently of the presence of atrial fibrillation (AF). METHODS: All subjects consecutively referred from January 2011 to October 2014 to the Cardiovascular Centre for CV risk assessment in primary prevention were selected...

Inflammatory arthritides are chronic diseases characterised by an increase in cardiovascular risk, largely attributable to the synergy between high-grade systemic inflammation and an elevated prevalence of traditional cardiovascular risk factors. Amongst the latter, insulin resistance and type 2 diabetes (T2D) play a key position. Previous studies demonstrated a potential insulin-sensiting effect of anti-TNF biologic medications. For converse, less is known about the role of newer biologics or small molecules...

Savitha Subramanian, Irl B Hirsch
PURPOSE OF REVIEW: Diabetes is the leading cause of kidney disease globally. Diabetic kidney disease (DKD) is a heterogeneous disorder manifested as albuminuria and/or decreasing GFR. Hyperglycemic burden is the major contributor to the development of DKD. In this article, we review the evidence for the contribution of glycemic variability and the pitfalls associated with use of hemoglobin A1c (A1C), the gold standard for assessment of glucose control, in the setting of DKD. RECENT FINDINGS: Glycemic variability, characterized by swings in blood glucose levels, can result in generation of mitochondrial reactive oxygen species, a putative inciting factor for hyperglycemia-induced alterations in intracellular metabolic pathways...

The engineering of cells as programmable devices has enabled therapeutic strategies that could not otherwise be achieved. Such strategies include recapitulating and enhancing native cellular functions and composing novel functions. These novel functions may be composed using both natural and engineered biological components, with the latter exemplified by the development of synthetic receptor and signal transduction systems. Recent advances in implementing these approaches include the treatment of cancer, where the most clinical progress has been made to date, and the treatment of diabetes...

BACKGROUND: Sirtuins (SIRT1-7) are a family of NAD+-dependent deacetylases that catalyze post-translational modifications of proteins. Together, they respond to metabolic challenges, inflammatory signals or hypoxic/oxidative stress, and are associated with aging and longevity. The role of Sirtuins in the regulation of fertility emerged in 2003 when a defective reproductive phenotype was observed in SIRT1-null mice. Although studies on Sirtuins in reproductive biology have been increasing in the last years, a recent comprehensive update on this issue is still lacking...

Differences in thyroid function status within the euthyroid range have been proposed to affect the development of (subclinical) atherosclerosis [1], as evidenced by a greater carotid artery intima media thickness and progression of coronary artery calcification in the context of low normal thyroid function, i.e. a higher thyroid stimulating hormone (TSH) or a lower free thyroxine (FT4) thyroid hormone in the euthyroid range [2,3]. Importantly, with respect to high density lipoproteins (HDL) the concept is emerging that abnormalities in function rather than low concentrations of HDL cholesterol per se may give rise to impaired atheroprotective potential of this lipoprotein fraction...

Cell therapy has become a momentum-gathering treatment strategy for a variety of diseases, including cancer, diabetes, hemophilia, and cardiomyopathy. However, clinical applications of conventional cell therapies have often been compromised by rapid decline in viability and function of the transplanted cells due to host recognition and subsequent foreign body rejection. Along this line, cell engineering technologies such as cell encapsulation within microcapsules and immobilization in porous scaffolds have been implemented to address the immunosuppression concerns...

BACKGROUND: Socially disadvantaged populations carry a disproportionate burden of diabetes-related morbidity and mortality. There is an emerging interest in quality improvement (QI) strategies in the care of patients with diabetes, however, the effect of these interventions on disadvantaged groups remains unclear. OBJECTIVE: This is a secondary analysis of a systematic review that seeks to examine the extent of equity considerations in diabetes QI studies, specifically quantifying the proportion of studies that target interventions toward disadvantaged populations and conduct analyses on the impact of interventions on disadvantaged groups...

Chromatin immunoprecipitation (ChIP) has gained importance to identify links between the genome and the proteome. Adipose tissue has emerged as an active tissue, which secretes a wide range of molecules that have been related to metabolic and obesity-related disorders, such as diabetes, cardiovascular failure, metabolic syndrome, or cancer. In turn, epigenetics has raised the importance in discerning the possible relationship between metabolic disorders, lifestyle and environment. However, ChIP application in human adipose tissue is limited by several factors, such as sample size, frozen sample availability, high lipid content and cellular composition of the tissue...

Skeletal muscle comprises approximately 40% of the total body mass. Preserving muscle health and function is essential for the entire body in order to counteract chronic diseases such as type II diabetes, cardiovascular diseases, and cancer. Prolonged physical inactivity, particularly among the elderly, causes muscle atrophy, a pathological state with adverse outcomes such as poor quality of life, physical disability, and high mortality. In murine skeletal muscle C2C12 cells, increased expression of the spermine oxidase (SMOX) enzyme has been found during cell differentiation...

In 2015, there were an estimated 12 million emergency department (ED) visits by patients aged 45 and over with diabetes, a rate of 92 per 1,000 persons aged 45 and over. The percentage of all ED visits for patients aged 45 and over made by those with diabetes increased from 2012 to 2015. The diabetes ED visit rate was about 2.5 times higher for those aged 75 and over than the rate for those aged 45-64. Twenty-four percent of the diabetes ED visits for those aged 45-64 had Medicare as the primary expected payment source, compared with 14% of the ED visits for patients aged 45-64 without diabetes...

Thrombospondin-1 (TSP-1), a matricellular protein and one of the first endogenous anti-angiogenic molecules identified, has long been considered a potent modulator of human diseases. While the therapeutic effect of TSP-1 to suppress cancer was investigated in both research and clinical settings, the mechanisms of how TSP-1 is regulated in cancer remain elusive, and the scientific answers to the question of whether TSP-1 expressions can be utilized as diagnostic or prognostic marker for patients with cancer are largely inconsistent...

PURPOSE: Cardiovascular calcifications (CVC) are present in up to 70% of non-diabetic dialysis patients. Sparse data are available on predictors of very long-term outcomes of such patients. The Belgrade Aachen Study on Calcification in Hemodialysis patients (BASCH study) aimed to study this using a comprehensive CVC assessment. METHODS: We prospectively analyzed 220 hemodialysis patients followed for a mean of 76 months (median 73 months, range 6-160 months). We compared patients deceased from cardiovascular diseases (CVD) and survivors...

Long noncoding RNAs (lncRNAs) are a class of non-protein-coding transcripts with the length longer than 200 nucleotides. Growing evidence suggests that lncRNAs, which were initially thought to be merely transcriptional "noise", participate in a wide repertoire of biological processes. It has been well established that lncRNAs not only play important roles in genomic regulation, transcription, posttranscriptional processes but are also implicated in the pathogenesis of human diseases including cardiovascular diseases, diabetes, neurodegenerative disorders, and cancer...
