The fatty acids found in nuts are important regulators of the metabolism. These acids are frequently associated with a reduction of serum cholesterol and body fat and a lower risk of developing cardiovascular disease. In this context, the aim of this study was to identify and quantify the nut oil fatty acids from Attalea phalerata and investigate their metabolic effects in rats with hyperlipidemia induced by a diet rich in fructose. Oleic and lauric acids were the major compounds found in the A. phalerata nut oil (APNO)...

PURPOSE OF REVIEW: Despite the recent advancements in diagnostic modalities and therapeutic options available, the pathophysiology of pericardial syndromes remains poorly understood. In this review article, we explore the possible links between cardiac adiposity and pericardial syndromes. RECENT FINDINGS: Over the last years, the notion of cardiac adipose tissue has radically changed, and its pivotal role in myocardial diseases has been acknowledged. Recent evidence suggests a cross-talk between epicardial fat and the heart...

REVIEW
Slava Berger, Vsevolod Y Polotsky
Obesity-related sleep breathing disorders such as obstructive sleep apnea (OSA) and obesity hypoventilation syndrome (OHS) cause intermittent hypoxia (IH) during sleep, a powerful trigger of oxidative stress. Obesity also leads to dramatic increases in circulating levels of leptin, a hormone produced in adipose tissue. Leptin acts in the hypothalamus to suppress food intake and increase metabolic rate. However, obese individuals are resistant to metabolic effects of leptin. Leptin also activates the sympathetic nervous system without any evidence of resistance, possibly because these effects occur peripherally without a need to penetrate the blood-brain barrier...

The study objective was to assess the prevalence of cardiovascular disease risk factors in patients treated for childhood cancer ( N = 101) and to determine the involvement of clinical (cancer type and therapy) and/or genetic ( FTO gene rs9939609 polymorphism) factors. Anthropometric features, laboratory findings, and standardized osteodensitometric indices (fat and lean mass) were considered. Overweight/obesity was found in 17.82% of the patients; however, central adiposity was found in as many as 42.5%. At least one abnormality in lipid metabolism was observed in 35...

Background -Pharmacogenomic studies have shown that ADCY9 genotype determines the effects of the cholesteryl ester transfer protein (CETP) inhibitor dalcetrapib on cardiovascular events and atherosclerosis imaging. The underlying mechanisms responsible for the interactions between ADCY9 and CETP activity have not yet been determined. Methods - Adcy9 -inactivated ( Adcy9 Gt/Gt ) and wild-type (WT) mice, that were or not transgenic for the CETP gene (CETPtg Adcy9 Gt/Gt and CETPtg Adcy9 WT ), were submitted to an atherogenic protocol (injection of an AAV8 expressing a PCSK9 gain-of-function variant and 0...

The prevalence of cardiovascular disease has increased among middle-aged women in the United States, yet has declined in middle-aged men. In experimental stroke, middle-aged females have larger strokes and greater inflammation than age-matched males or younger females. The mechanism underlying this shift from an "ischemia-protected" to an "ischemia-sensitive" phenotype in aging females is unknown. One potential factor is an age-related increase in systemic factors that induce inflammation...

BACKGROUND: Perivascular adipose tissue (PVAT) accelerates plaque progression and increases cardiovascular risk. We tested the hypothesis that PVAT contributed to plaque vulnerability and investigated whether endoplasmic reticulum stress (ER stress) in PVAT played an important role in vulnerable plaque. METHODS: We transplanted thoracic aortic PVAT or subcutaneous adipose tissue as a control, from donor mice to carotid arteries of recipient apolipoprotein E deficient (apoE-/- ) mice after removing carotid artery collar placed for 6 weeks...

BACKGROUND: The prevalence of metabolic syndrome (MetS) and MetS-related stroke is set to increase dramatically in coming decades. MetS is a complex disease that includes endothelial dysfunction, insulin resistance, diabetes, hypertension, ectopic obesity, and dyslipidaemia, and an increased risk of cardiovascular events. However, there are no systematic analyses, or well-conducted meta-analyses to evaluate the relationship between epicardial adipose tissue (EAT) and (MetS). The aim of this study is to examine this association of EAT with MetS in different ages and sex...

Nutritional changes in the development (intrauterine life and postnatal period) may trigger long-term pathophysiological complications such as obesity and cardiovascular disease. Metabolic programming leads to organs and tissues modifications, including adipose tissue, with increased lipogenesis, production of inflammatory cytokines, and decreased glucose uptake. However, stem cells participation in adipose tissue dysfunctions triggered by overfeeding during lactation has not been elucidated. Therefore, this study was the first to evaluate the effect of metabolic programming on adipose mesenchymal stem cells (ASC) from mice submitted to overfeeding during lactation, using the litter reduction model...

INTRODUCTION: Increased systemic inflammation is engaged likely plays a significant role in the development of adult cardiometabolic diseases such as insulin resistance, dyslipidemia, atherosclerosis, and hypertension. The complement system is part of the innate immune system and plays a key role in in regulation inflammation. Of particular importance is the activation of complement components C3 and C4. C3 is produced primarily by the liver but is also produced in adipocytes, macrophages and endothelial cells, all of which are present in adipose tissue...

OBJECTIVES: Obesity leads to deleterious effects on not only cardiovascular health but also on the reproductive health of women. We estimate the prevalence of menstrual irregularity and of polycystic ovarian syndrome (PCOS) in Samoan women, among whom obesity prevalence is extremely high. We explore the association of these reproductive health conditions with adiposity, cardiometabolic risk factors, and androgen levels. METHODS: A cross-sectional sample of Samoan women 25-39 years of age (n = 470) from a larger population-based genome-wide association study of adiposity and cardiometabolic disease was assessed for the prevalence of oligomenorrhea/amenorrhea (OM/AM) using a self-reported questionnaire...

A constellation of metabolic disorders, including obesity, dysregulated lipids, and elevations in blood glucose levels, has been associated with cardiovascular disease and diabetes. Analysis of data from recently published genome-wide association studies (GWAS) demonstrated that reduced-function polymorphisms in the organic cation transporter, OCT1 (SLC22A1), are significantly associated with higher total cholesterol, low-density lipoprotein (LDL) cholesterol, and triglyceride (TG) levels and an increased risk for type 2 diabetes mellitus, yet the mechanism linking OCT1 to these metabolic traits remains puzzling...

BACKGROUND: Achondroplasia is a rare genetic disease is characterized by abnormal bone development and early obesity. While the bone aspect of the disease has been thoroughly studied, early obesity affecting approximately 50% of them during childhood has been somewhat neglected. It nevertheless represents a major health problem in these patients, and is associated to life-threatening complications including increasing risk of cardiovascular pathologies. We have thus decided to study obesity in patients and to use the mouse model to evaluate if soluble FGFR3 therapy, an innovative treatment approach for achondroplasia, could also impact the development of this significant complication...

The aim of this study was to assess the relation of wrist circumference with changes in left ventricular (LV) structure in a population of overweight/obese children and adolescents. One hundred and six children and adolescents were consecutively enrolled. In all subjects body weight, height, wrist circumference, waist circumference, body mass index-standard deviation score, fasting glucose, insulin, lipid profile, and blood pressure were evaluated. All subjects underwent echocardiographic assessment, and the following parameters were evaluated: LV dimension at end diastole and LV dimension at end systole, LV posterior wall thickness at end diastole and LV posterior wall thickness at end systole, interventricular septal thickness at end diastole and interventricular septal thickness at end systole, LV mass, and epicardial adipose tissue (EAT)...

Primary hypertension is not just an adult disorder. Current US population data on children and adolescents demonstrate a prevalence of elevated blood pressure (BP) and hypertension combined of over 10%. Recent reports from prospective cohort studies describe an association of high BP in childhood with hypertension in young adulthood. Excess adiposity is strongly associated with higher BP in childhood and increases risk for hypertension in adulthood. In addition to overweight/obesity, other exposures that raise the risk for high BP include low birthweight, dietary sodium, and stress...

SCOPE: Low fiber intake is associated with increased risk for cardiovascular disease (CVD) and cancer. However, the underlying mechanisms are not well understood. We tested two hypotheses: 1) dietary fiber would be associated with DNA methylation levels; 2) those DNA methylation changes would be associated with visceral adiposity and inflammation. We also explored the possibility that the associations between fiber and DNA methylation levels might be confounded with folic acid intake as sensitivity analysis...

Cardiac autonomic neuropathy (CAN) is an early cardiovascular complication of diabetes occurring before metabolic derangement is evident. The cause of CAN remains elusive and cannot be directly linked to hyperglycemia. Recent clinical data report cardioprotective effects of some antidiabetic drugs independent of their hypoglycemic action. Here, we used a rat model receiving limited daily increase in calories from fat (HC diet) to assess whether mild metabolic challenge led to CAN in absence of interfering effects of hyperglycemia, glucose intolerance, or obesity...
