Obesity, along with hypertrophy of the adenoids and the tonsils, represents one of the major risk factors for obstructive sleep apnea (OSA) in children. Obesity is associated with an increase in the prevalence and the severity of OSA and is a major factor in the persistence and aggravation of OSA over time. Neurocognitive dysfunction and abnormal behavior are the most important and frequent end-organ morbidities associated with OSA in children. Other deleterious consequences such as cardiovascular stress and metabolic syndrome are less common in children than in adults with OSA...

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...

Obesity, insulin resistance, type 2 diabetes mellitus and cardiovascular disease form a metabolic disease continuum that has seen a dramatic increase in prevalence in developed and developing countries over the past two decades. Dyslipidaemia resulting from hypercaloric diets is a major contributor to the pathogenesis of metabolic disease, and lipid-lowering therapies are the main therapeutic option for this group of disorders. However, the fact that dysfunctional lipid metabolism extends far beyond cholesterol and triglycerides is becoming increasingly clear...

BACKGROUND: Blood pressure (BP) decreases in the first weeks after Roux-and-Y gastric bypass surgery. Yet, the pathophysiology of the BP lowering effects observed after gastric bypass surgery are incompletely understood. METHODS: We evaluated BP, systemic hemodynamics and baroreflex sensitivity in 15 obese women (mean age 42±7 yrs, body mass index 45±6 kg/m(2)) two weeks before and six weeks following Roux-and-Y gastric bypass surgery. RESULTS: Six weeks after gastric bypass surgery mean body weight decreased by 13±5 kg (10%, p<0...

OBJECTIVE: Ceramides are molecular lipids implicated in apoptosis, inflammation, obesity, and insulin resistance. An earlier study reported that ceramides were associated with fatal outcome among patients with coronary heart disease. Here, we examined whether ceramides are associated with major adverse cardiovascular events (MACEs) among apparently healthy individuals. APPROACH AND RESULTS: FINRISK 2002 is a population-based risk factor survey, which recruited men and women aged 25 to 74 years...

OBJECTIVES: Obesity is an important determinant of cardiovascular risk. However, the optimal measure and cutoffs in Latin America are not defined. We sought to assess the relationship between body mass index (BMI), waist circumference (WC) and waist-to-height ratio (WHtR) with risk factor prevalence and estimated coronary heart disease (CHD) risk and to assess if recommended cutoffs apply to the Chilean population. STUDY DESIGN AND SETTING: Data from 2,200 men and 3,216 women from the Chilean Health Survey 2009-2010 were analyzed...

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...

BACKGROUND: Plasminogen activator inhibitor-1 (PAI-1) is the primary inhibitor of the endogenous fibrinolytic system and is known to be increased in obesity, insulin resistance and non-alcoholic fatty liver disease (NAFLD). We previously demonstrated that PAI-1 levels were closely related to the amount of hepatic steatosis in children. OBJECTIVES: The aim of this study was to characterize plasma PAI-1 in relationship to severity of inflammation and fibrosis, as well as to plasma lipids in children with NAFLD...

The prevalence of obesity among adults and children worldwide has reached epic proportions and has become a major independent risk factor for the development of heart failure (HF), in addition to a contributor of hypertension and cardiovascular disease. The implications of obesity in the development of HF involve adverse effects on cardiac structure and function. Despite all of this, in the setting of chronic HF, excess body mass is associated with improved clinical outcomes, demonstrating the presence of an obesity paradox...

Obesity is a major global health problem, and its multisystem effects are inextricably linked with elevated cardiovascular risk and adverse outcomes. The cardiovascular benefits of reversing obesity in adults are well-established. Compared with other weight-loss strategies, programmes that incorporate bariatric surgery for weight loss are beneficial for sustained BMI reduction. A marked improvement in cardiovascular risk factors, including hypertension, dyslipidaemia, inflammation, and type 2 diabetes mellitus, has been observed after bariatric surgery...

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...

Stress is associated with many diseases and dysfunctions, such as depression, cardiovascular alterations, immunological function disorder, inflammation, obesity, and insulin resistance. Stress-induced inflammation is associated with the genesis of insulin resistance. Stress activates hypothalamic pituitary adrenal axis, Renin Angiotensin System pathway, and sympatho-adrenal system, all of which are involved in the production of cytokines, causing the negative downregulation of insulin signaling either by phosphorylating serine residues of IRS or by inhibiting the activity of Akt leading to insulin resistance...

Obesity is an ongoing global epidemic and has adverse consequences for cardiovascular health. Obesity is often associated with hypertension, which is, itself, a common condition and an important cause of morbidity and mortality worldwide. Although animal models of obesity have provided extensive data on the links between obesity and hypertension, a greater understanding of the pathways linking obesity and hypertension in humans is likely to assist translation of animal data, and may, itself, identify important treatment strategies...

Like other biguanide agents, metformin is an anti-hyperglycemic agent with lower tendency towards hypoglycemia compared to other anti-diabetic drugs. Given its favorable effects on serum lipids, obese body habitus, cardiovascular disease, and mortality, metformin is recommended as the first-line pharmacologic agent for type 2 diabetes in the absence of contraindications. However, as metformin accumulation may lead to type B non-hypoxemic lactic acidosis, especially in the setting of kidney injury, chronic kidney disease, and overdose, regulatory agencies such as the United States Food and Drug Administration (FDA) have maintained certain restrictions regarding its use in kidney dysfunction...

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)...
