Adiponectin is one of the most abundant adipokines secreted from adipose tissue. It acts as an endogenous insulin sensitizer and plasma concentrations are inversely correlated with obesity and metabolic syndrome. A decrease in plasma adiponectin levels normally indicates increased hormonal activity of the visceral lipid tissue, which is associated with decreased insulin sensitivity. It may therefore be considered a valuable biomarker for elucidating the underlying deteriorations resulting in type 2 diabetes and macrovascular disease...

Recognition of the close relationship of nonalcoholic fatty liver disease (NAFLD) with diabetes mellitus 2, obesity, metabolic syndrome, and cardiovascular disease has stimulated growing interest in NAFLD as a public health problem. Serum alanine aminotransferase (ALT) has been proposed as a marker of NAFLD, but levels are within the range currently considered "normal" in a large proportion of NAFLD subjects.The aim of the study was to determine the diagnostic accuracy of serum ALT for identifying individuals with NAFLD, using 3-Tesla (T) magnetic resonance spectroscopy (H-MRS)...

Growth hormone (GH) is an essential element for normal growth. However, reports of normal growth without GH have been made in patients who have undergone brain surgery for craniopharyngioma. Normal growth without GH can be explained by hyperinsulinemia, hyperprolactinemia, elevated leptin levels, and GH variants; however, its exact mechanism has not been elucidated yet. We diagnosed a female patient aged 13 with combined pituitary hormone deficiency (CPHD) caused by pituitary stalk interruption syndrome (PSIS)...

CONTEXT AND OBJECTIVE: The increase in arterial stiffness in patients with the metabolic syndrome is strongly related to the amount of visceral adipose tissue. In clinical practice, anthropometric measurements such as BMI and waist circumference are commonly used to assess general and abdominal adiposity. Waist circumference is a composite measure of subcutaneous and visceral abdominal adipose tissue. As the distribution of intra-abdominal fat differs between men and women, we investigated the sex-specific associations between different anthropometric measures for general and abdominal obesity with arterial stiffness...

PURPOSE OF REVIEW: The pathophysiologies of nonalcoholic fatty liver disease (NAFLD), metabolic syndrome, and cardiovascular disease are closely interlinked and associated with atherogenic dyslipidemia. Liver and cardiovascular disease may silently progress to advanced stages if alarming signs, such as abdominal obesity, elevated fasting and postprandial triglycerides, and low HDL cholesterol are overlooked. We review the metabolic mechanisms in NAFLD at the cellular level in the context of standard clinical lipid measurements...

BACKGROUND AND OBJECTIVE: Advanced glycation end-products (AGEs) are a marker of metabolic memory. Their levels increases when oxidative stress, inflammation, or chronic hyperglycemia exists. The role of morbid obesity in AGE levels, and the impact of bariatric surgery on them are unknown. PATIENTS AND METHOD: An observational study with three sex- and age-matched cohorts: 52 patients with obesity, 46 patients undergoing bariatric surgery in the last 5 years, and 46 control subjects...

INTRODUCTION: Cushing syndrome (CS), an endogenous hypercortisolemic condition with increased cardiometabolic morbidity, leads to development of abdominal obesity, insulin resistance, diabetes and proatherogenic dyslipidemia. Zinc alpha-2 glycoprotein (ZAG) is a recently characterized lipolytic adipokine implicated in regulation of adipose tissue metabolism and fat distribution. In vitro and animal studies suggest that glucocorticoids interact with ZAG secretion and action. To assess the relationship between ZAG and glucocorticoids in a human model of hypercortisolism, circulating ZAG levels were tested in patients with CS and its counterpart controls...

OBJECTIVE: The theory of fetal programming suggests that low birth weight (LBW) predisposes to greater food intake and increases the chance of overweight and obesity, which are in turn associated to conditions such as metabolic syndrome (MS) and acanthosis nigricans. The study objective was to ascertain whether an association exists between MS, LBW, intake of high-calorie diets, and acanthosis nigricans in children and adolescents with overweight or obesity. MATERIAL AND METHODS: A case-control was conducted on 100 children who attended the overweight and obesity outpatient clinic of the OPD Hospital Civil de Guadalajara "Fray Antonio Alcalde"...

Nuclear factor E2-related factor 2 (Nrf2) is a transcription factor known to induce the expression of a variety of antioxidant and detoxification genes. Recently, increasing evidence has revealed roles for Nrf2 in glucose, lipid, and energy metabolism; however, the exact functions of Nrf2 in hepatocyte biology are largely unclear. In the current study, the transient knockdown of Nrf2 via siRNA transfection enhanced the glucose uptake of fasting AML12 hepatocytes to 325.3 ± 11.1% ( P < 0.05) of that of untransfected control cells...

Bariatric and metabolic surgery has become the clinical hot topic of the treatment of metabolic syndromes including obesity and diabetes mellitus, but how to choose the appropriate surgical procedure remains the difficult problem in clinical practice. Clinical guidelines of American Society for Metabolic and Bariatric Surgery(ASMBS)(version 2013) introduced the procedures of bariatric and metabolic surgery mainly including biliopancreatic diversion with duodenal switch(BPD-DS), laparoscopic adjustable gastric banding (LAGB), laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic sleeve gastrectomy(LSG)...

Pediatric overweight and obesity is an emerging public health priority as rates have rapidly increased worldwide. Obesity is often clustered with other metabolic abnormalities including hypertension, dyslipidemia, and insulin resistance, leading to increased risk of cardiovascular disease. This cluster of risk factors, termed the metabolic syndrome, has traditionally been reported in adults. However, with the increased prevalence of pediatric obesity, the metabolic syndrome is now evident in children and adolescents...

The prevalence of metabolic syndrome is increasing in African populations, and is particularly high in Black South African women (42%) vs women in the United Kingdom (23%) and the United States of America (36%). This population group is also known to have the highest prevalence of obesity in the sub-Saharan African region (42%), and consequently, a high risk of non-communicable diseases. In this article, we discuss factors (abdominal subcutaneous fat, visceral fat, lean mass, adiponectin, leptin, vitamin D, smoking and menopausal status) that have been investigated for their possible association with metabolic syndrome in African women, and discuss some recommendations for management of the syndrome...

Individuals with Fragile X Syndrome (FXS) may be affected by several comorbid conditions, both behavioral and medical. Growth findings suggest that they are at an increased risk for obesity and overeating. The Prader-Willi phenotype (PWP) of FXS occurs in less than 10% of patients but it is associated with severe hyperphagia, lack of satiation and morbid obesity. Metformin is a drug used in individuals with high risk for diabetes type 2, obesity or impaired glucose tolerance. It has had a strong safety profile in children and adults with type 2 diabetes and obesity...

Obesity is metabolic disorder that increases the risk of diabetes, heart disease, and other metabolic syndromes in human beings. One sign of diabetes is increased blood glucose levels in the body. Glucose levels increase due to problems with insulin secretion or insulin resistance. Maturity onset of diabetes of the young is more common in adults and occurs due to insulin resistance. Both diabetes and obesity are major problems that are responsible for the death of millions of individuals every year, worldwide...

BACKGROUND: Excess weight (overweight and obesity) is the major modifiable risk factor for type 2 diabetes mellitus (T2DM) and other non-communicable diseases. However, excess weight may not be as predictive of diabetes risk as once thought. While excess weight and other obesity-related non-communicable diseases are of growing concern in low-middle income countries in Latin America, there is limited research on risk factors associated with T2DM in adolescents. This study investigated prevalence of overweight, obesity, prediabetes, diabetes and metabolic syndrome in adolescents in Ecuador...
