Adipose cardiovascular

Maria das Graças Coelho de Souza, Luiz Guilherme Kraemer-Aguiar, Eliete Bouskela
Obesity is a crescent epidemic in the world, affecting more than half a billion of adults worldwide. Obesity is associated to main cardiovascular risk factors, such as insulin resistance, type 2 diabetes mellitus, high blood pressure and dyslipidemia. The excessive adiposity causes a dysregulation of adipokines secretion by adipose tissue, upregulating the expression of pro-inflammatory adipokines and downregulating the anti-inflammatory ones. This scenario contributes for the appearance of atherosclerosis...

BACKGROUND & AIMS: Non-alcoholic fatty liver disease (NAFLD) is associated with increased risk of hepatic, cardiovascular, and metabolic diseases. High-protein diets, rich in methionine and branched chain amino acids (BCAAs), apparently reduce liver fat but may induce insulin resistance. We investigated the effects of diets high in animal protein vs plant protein, which differ in levels of methionine and BCAA, in subjects with type 2 diabetes and NAFLD. We examined levels of liver fat, lipogenic indices, markers of inflammation, serum levels of fibroblast growth factor 21 (FGF21), and activation of signaling pathways in adipose tissue...

INTRODUCTION AND OBJECTIVES: Obesity is an important cardiovascular risk factor and the location of fat deposits seems to be an important determinant of its metabolic impact. Visceral adipose tissue (VAT) exerts a harmful effect on metabolic homeostasis, but few longitudinal studies have evaluated the prognostic impact of the ratio of VAT to subcutaneous adipose tissue (SAT). This study aimed to evaluate whether the VAT/SAT ratio was associated with all-cause mortality and cardiac events...

Exercise training can reduce hepatic fat accumulation and cardiovascular risk among patients with nonalcoholic fatty liver disease (NAFLD), but how long these benefits extend beyond the period of active intervention is unclear. Intrahepatic triglyceride (IHTG) content measured by proton magnetic resonance spectroscopy, and metabolic risk factors were assessed among 220 obese subjects with NAFLD who were randomly assigned to vigorous-moderate exercise, moderate exercise, or control over the subsequent 1 year after 12-month exercise intervention...

INTRODUCTION: The main changes in the body composition refer to the increase of adipose tissue and/or the decrease of muscular mass, and these changes have effect in many clinical outcomes. Sarcopenic obesity (SO) consists of the presence of excessive adipose tissue and deficit of muscular mass simultaneously. People with SO may have synergistic effect due to obesity and sarcopenia, with increases cardiovascular risk more than obesity itself. OBJECTIVE: To describe the findings in the literature about the association between SO and risk factors and/or cardiometabolic disease (CMD) or cardiovascular disease (CVD)...

BACKGROUND: Cardiovascular diseases are currently the commonest cause of death worldwide. Different strategies for their primary prevention have been planned, taking into account the main known risk factors, which include an atherogenic lipid profile and visceral fat excess. METHODS: The study was designed as a randomized, parallel, single-center study with a nutritional intervention duration of 12 weeks. Whole soy foods corresponding to 30 g/day soy protein were given in substitution of animal foods containing the same protein amount...

Management of hypertension in diabetes is critical for reducing cardiovascular mortality and morbidity. Dietary approaches for controlling high blood pressure have historically focused on sodium. Thus, many guidelines recommend that patients with type 2 diabetes reduce high sodium intake. Nonetheless, the potential benefits of sodium reduction are debatable. The kidney has a crucial role in glucose filtration and reabsorption in addition to its regulation of fluid and electrolyte homeostasis. A key factor linking sodium uptake and glucose transport is the sodium-glucose cotransporter 2 (SGLT2) in renal proximal tubular cells...

OBJECTIVE: The pineal hormone melatonin, which regulates the body's circadian rhythm, possesses anti-oxidative and anti-inflammatory effects and thereby improves metabolic disorders. Ramelteon is a potent and highly selective agonist of melatonin receptors and attenuates age-associated hypertension and body weight gain in spontaneously hypertensive rats. However, the effects of ramelteon on cardiovascular and metabolic disorders in metabolic syndrome (MetS) remain unclear. We investigated the effects of ramelteon on cardiac and adipose tissue pathology in a rat model of MetS...

Obesity is associated with an increased risk of morbidity and mortality from cardiometabolic diseases, but not all obese individuals are at increased risk. This phenotype of obesity is referred to as "metabolically healthy obesity (MHO)." MHO describes a cohort of the obese population with relatively low risk of cardiovascular and metabolic diseases. Although MHO has favorable metabolic profiles such as insulin sensitivity, low inflammatory markers, and low body fat, there remains a substantial unexplained variance...

Atrial natriuretic peptide (ANP) and B-type natriuretic peptide (BNP) are the cardiac natriuretic peptides (NP), true "cardiometabolic" hormones well known for their renal, endocrine and cardiovascular activities leading to reduced sodium reabsorption and arterial blood pressure. These effects are mainly mediated by the second messenger cGMP that also stimulates lipolysis, mitochondriogenesis and a thermogenic program with potency similar to catecholamines. Two distinct NP receptors modulate the final response to cardiac NP: the cGMP-signaling receptor NPRA and the clearance receptor NPRC...

Metabolic syndrome (MetS) is a cluster of major cardiovascular risk factors like glucose intolerance, dyslipidemia, and high blood pressure. The most important risk factor for MetS is abdominal obesity. Also, insulin resistance is considered as an underlying pathophysiology of MetS. Under the current paradigm, excess calorie intake and physical inactivity are major contributors to obesity and insulin resistance.Meanwhile, many environmental chemicals have recently received attention as a significant contributor to obesity and obesity-related metabolic dysfunction...

BMI is a proxy measure for adiposity in population-based studies and it is well established that increasing body fat is strongly associated with component features of the metabolic syndrome (MetS), such as dyslipidaemia (low high density lipoprotein cholesterol (HDL-C) and high triglyceride concentrations, increased glucose concentrations, high blood pressure, hypertension, and type 2 diabetes. Whether any or all of these components of the MetS account for relationships between body fatness and all cause mortality is uncertain, but we have recently shown in a large Korean cohort that co-existing cardiovascular disease (CVD), diabetes or hypertension explained much of the increased risk of CVD mortality in obese individuals...

Cardiovascular diseases (CVD) are major causes of death and illness worldwide. In recent decades an increased prevalence of CVD mortality has been reported in low-medium income countries, which has been associated with changes in life styles, deficiencies in health systems and the persistence of social inequities.The metabolic syndrome comprises a cluster of cardiometabolic risk factors, with insulin resistance and increased adiposity as its central features. Identifying individuals with metabolic syndrome is important due to its association with an increased risk of coronary heart disease and type 2 diabetes mellitus (DM2)...

PURPOSE: Environmental and nutritional disorders during perinatal period cause metabolic dysfunction in the progeny and impair human health. Advanced glycation end products (AGEs) are primarily produced during metabolism of excess blood glucose, which is observed in diabetes. Methylglyoxal (MG) is a precursor for the generation of endogenous AGEs, which disturbs the metabolism. This work aimed to investigate whether the maternal MG treatment during lactation programs the progeny to metabolic dysfunction later in life...

Long-term use of antiretroviral therapy (ART) increases the risk of developing lipodystrophy. Few studies from Africa have used longitudinal data to assess the development of lipoatrophy and lipohypertrophy. We use clinical anthropometry and dual-energy X-ray absorptiometry (DEXA) to describe changes in body fat distribution over a 24-month period in individuals initiated on ART. A convenience sample of black South Africans (55 men and 132 women) were recruited and followed for 24 months after commencing ART...

Adipokines are cytokines produced mainly by adipose tissue, besides many other tissues such as placenta, ovaries, peripheral-blood mononuclear cells, liver, muscle, kidney, heart, and bone marrow. Adipokines play a significant role in the metabolic syndrome and in cardiovascular diseases, have implications in regulating insulin sensitivity and inflammation, and have significant effects on growth and reproductive function. The objective of this review was to analyze the functions known today of adiponectin, leptin, resistin, and visfatin from placenta throughout childhood and adolescence...
