PURPOSE: Age-related non-communicable chronic diseases (ArCDs) are the leading cause of mortality. The major metabolic risk factor for their development is the metabolic syndrome (MetS), defined as a clustering of risk factors of metabolic origin such as abdominal obesity, high blood pressure, dyslipidemia and high fasting glycemia. There is increasing observational and experimental evidence that improving diet and the use of metformin (a calorie-restriction mimetic drug) may modify the risk of developing MetS and ArCD...

Two Caucasian girls, both of normal weight and body mass indices, were diagnosed with type A insulin resistance (IR) in childhood. Case 1 presented with premature adrenarche aged 7 years, then by age 12 years had hirsutism, acne, acanthosis nigricans, and asymptomatic diabetes. Subsequent investigation revealed raised adiponectin (15.3 mg/L) and heterozygous p.Pro1205Leu mutation in the INSR gene encoding the insulin receptor. She experienced postprandial hypoglycaemia on metformin; acarbose was trialled and discontinued aged 16 years, as she became normoglycaemic...

BACKGROUND: Intestinal gluconeogenesis (GNG) may play an important role in glucose homeostasis, but there is little information about the condition in humans. OBJECTIVES: To study the relationship between intestinal GNG and insulin resistance, its association with the evolution of morbidly obese patients after bariatric surgery, and the effect of insulin and or leptin. SETTING: Regional university hospital, Malaga (Spain). METHODS: Jejunal mRNA expression of genes involved in GNG was analyzed in 3 groups of morbidly obese patients who underwent Roux-en-Y gastric bypass: with low insulin resistance (MO-low-IR), with high insulin resistance (MO-high-IR), and with type 2 diabetes treated with metformin (MO-metf-T2D)...

Radix Pueraria lobata (RP) has been reported to prevent obesity and improve glucose metabolism; however, the mechanism responsible for these effects has not been elucidated. The mechanism underlying anti-obesity effect of RP was investigated in high-fat diet (HFD) induced obese mice and skeletal muscle cells (C2C12). Five-week-old C5BL/6 mice were fed a HFD containing or not containing RP (100 or 300 mg/kg) or metformin (250 mg/kg) for 16 weeks. RP reduced body weight gain, lipid accumulation in liver, and adipocyte and blood lipid levels...

BACKGROUND: Polycystic ovary syndrome (PCOS) is highly associated with an ovulatory infertility, features of the metabolic syndrome, including obesity, insulin resistance and dyslipidemia. Serum concentrations of high sensitive C-reactive protein (hs-CRP) were significantly higher in obese than in non-obese PCOS patients at baseline, suggesting a relationship between elevated hs-CRP levels and obesity. The aim of this study was to evaluate whether cycle day 3 hs-CRP levels before clomiphene citrate (CC) treatment would predict cycle outcomes in women with PCOS...

AIMS: To improve insulin sensitivity, insulin-sensitizing drugs such as metformin are commonly used in overweight and obese T1D patients. Similarly to metformin, D-chiro-inositol (DCI), as putative mediator of intracellular insulin action, can act as insulin sensitizer. The aim of this pilot study was to evaluate the hypothesis that DCI plus folic acid may improve glucose control reducing insulin resistance in overweight or obese T1D patients. METHODS: A 24-week randomized control trial was carried out in 26 overweight or obese T1D patients, undergoing intensive insulin therapy...

BACKGROUND: The prevalence of type 2 diabetes mellitus (T2DM) and obesity is increasing in Korea. Clinical studies in patients with T2DM have shown that combining the glucagon-like peptide-1 receptor agonist exenatide twice daily with basal insulin is an effective glucose-lowering strategy. However, these studies were predominantly conducted in non-Asian populations. METHODS: We conducted a subgroup analysis of data from a multinational, 30-week, randomized, open-label trial to compare the effects of exenatide twice daily (n=10) or three times daily mealtime insulin lispro (n=13) among Korean patients with T2DM inadequately controlled (glycosylated hemoglobin [HbA1c] >7...

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in females and is often associated with a number of cardiometabolic disorders such as central obesity, dyslipidaemia, hypertension, insulin resistance, hyperinsulinaemia, glucose intolerance and type 2 diabetes mellitus (T2DM). Glucagon-like peptide-1 (GLP-1), a gut hormone secreted after a meal, enhances glucose-stimulated insulin secretion and additionally suppresses appetite and gastric motility. Most studies found impaired GLP-1 kinetics in obese individuals, whereas small studies in PCOS reported reduced, normal or even elevated GLP-1 levels...

Diabetes mellitus (DM) is considered as a complex metabolic disease because it affects the metabolism of glucose and other metabolites. Although many diabetes studies have been conducted in animal models throughout the years, the pathogenesis of this disease, especially between lean diabetes (ND + STZ) and obese diabetes (OB + STZ), is still not fully understood. In this study, the urine from ND + STZ, OB + STZ, lean/control (ND), and OB + STZ rats were collected and compared by using (1)H NMR metabolomics...
