Genistein and endothelial function in postmenopausal women with metabolic syndrome

2013

BackgroundPrevious data have suggested that genistein could exert beneficial effects on endothelial function and on predictors of cardiovascular risk in healthy postmenopausal women. In a randomized clinical trial, we studied the effects of genistein on endothelial function in postmenopausal women with metabolic syndrome (MS). MethodsTwenty postmenopausal women with MS, according to modified NCEP-ATP III criteria were randomly assigned to receive placebo or genistein (54mg/day) for 6months, along with a Mediterranean-style diet. Postmenopausal women without MS (n=15), served as controls. The primary goal was the assessment of endothelial function by flow-mediated vasodilation (FMD) of brach…

Incretin-Based Therapies, Glucometabolic Health and Endovascular Inflammation

2013

Incretin peptides are a group of gastrointestinal hormones that play a prominent role in the regulation of glucose metabolism. Incretin-based therapies (IBTs) have recently emerged as an important treatment option for patients with type 2 diabetes mellitus (T2DM). These pharmaceutical agents may be specially well suited for patients who are overweight or obese with primarily post-meal glucose peaks, and in whom traditional first-line oral agents have failed to maintain adequate glycemic control. There are 2 classes of IBTs: the dipeptidyl peptidase-4 (DPP-4) inhibitors and the glucagon-like peptide 1 (GLP-1) receptor agonists. The ultimate effect of both types of agents is to augment GLP-1 …

Therapy with non-invasive ventilation in patients with obstructive sleep apnoea: effects on atherogenic lipoprotein phenotype.

2009

Patients with obstructive sleep apnoea are at increased risk of atherosclerotic morbidity and mortality. Abnormalities in lipid metabolism that occur in response to chronic intermittent hypoxia in patients with sleep-disordered breathing may increase the cardiovascular risk in an already susceptible population. Atherogenic lipoprotein phenotype and small, dense LDL have an independent predictive role for future cardio- and cerebro-vascular events in patients with the metabolic syndrome. Therefore, testing the hypothesis that therapy of obstructive sleep apnoea may reduce atherogenic lipoprotein phenotype might have significant clinical implications. We suggest that abolition of obstructive …

Postprandial metabolism: from research to clinical practice.

2013

Over the last decade, the importance of postprandial metabolism has increased, given that it is the physiological state of humans in modern society. Moreover, postprandial lipemia is considered as a key player in the development of the most important cardiometabolic diseases. In this regard, postprandial lipemia has become more important, since it has been demonstrated that nonfasting triglycerides (TGs) are independent predictors of the risk of cardio vascular disease (CVD) [1,2]. Interestingly, the postprandial phase has been associated with increased inflammation and oxidation, which influences vascular function through a permanent endothelial aggression by atherogenic lipoprotein. TGs a…

Not all women diagnosed with PCOS share the same cardiovascular risk profiles

2009

Although definitive and confirmatory data are lacking, women with polycystic ovary syndrome (PCOS) are considered to be at increased risk for cardiovascular and metabolic disease. In recent years, the diagnosis of PCOS has broadened considerably to result in several phenotypes. Here we review the evidence for cardiovascular and metabolic risks in PCOS in the classic disorder and the various phenotypes. We conclude that not all women with PCOS should be considered as being similar in terms of cardiovascular risk profiles.

Magnesium and Type 2 Diabetes: An Update

2015

The link between magnesium (Mg) deficiency and type 2 diabetes mellitus is well known. Type 2 diabetes is frequently associated with both extracellular and intracellular Mg deficits. A chronic latent Mg deficit or an overt clinical hypomagnesaemia is common in subjects with type 2 diabetes, especially in those with poorly controlled glycemic profiles. Insulin and glucose are important regulators of Mg metabolism. Intracellular Mg plays a key role in regulating insulin action, insulin-mediated-glucose-uptake and vascular tone. Reduced intracellular Mg concentrations result in a defective tyrosine-kinase activity, postreceptorial impairment in insulin action and worsening of insulin resistanc…

Protein oxidation in metabolic syndrome

2013

Purpose: Oxidative stress plays a pivotal role in the pathogenesis of the metabolic syndrome and in the progression of its complications. Carbonylated proteins are a stable marker of severe oxidative stress because damage to the protein structure is irreversible and may cause an inhibition of their enzymatic activity or an increased susceptibility to proteolysis. There are few data regarding protein oxidation in metabolic syndrome, although elevated levels of carbonyl groups are often detected in subjects with obesity, diabetes mellitus, hypertension or dyslipidemia, well-known components of the metaboic syndrome. In particular, obesity, insulin resistance and diabetes mellitus are frequent…

METABOLIC SYNDROME FOLLOW-UP IN MENOPAUSE: A MULTIDISCIPLINARY APPROACH TO REDUCE THE CARDIOVASCULAR RISK

Obesity, Adipokines and Metabolic Syndrome in Polycystic Ovary Syndrome

2012

The complex mechanisms linking fat excess to metabolic syndrome are not well understood, but several experimental studies have shown that altered production of adipokines plays a main role in development and progression of this disorder. In particular, reduced secretion of adiponectin has a crucial role in inducing insulin resistance but also in determining the clustering of elevated triglycerides and small, dense LDL particles. Increased leptin secretion may be responsible for sympathetic nervous system overactivity and hypertension, while reduced omentin may have an important permissive role in the development of atherogenic processes. Finally, cytokines and other adipokines (resistin, vi…

Gestational diabetes and the metabolic syndrome: Can obesity and small, dense low density lipoproteins be key mediators of this association?

2013

Gestational diabetes mellitus (GDM) represents a condition of glucose intolerance with first appearance or recognition at the time of a pregnancy, associated with an inadequate pancreatic response to the advanced insulin resistance of the later stages of pregnancy, and accompanied by enhancing β-cell mass and secretion of insulin. Women who had GDM exhibit a higher risk for later advent of type 2 diabetes mellitus (T2DM) and cardiovascular diseases (CVD). Additionally, previous GDM has been proposed as independently correlated with higher risk for development of atherosclerosis in a healthy population, similar to the metabolic syndrome (MetS) and independently of the presence of established…
