Type 2 diabetes is often associated with obesity, dyslipidemia and cardiovascular anomalies and is a major health problem approaching global epidemic proportions. Insulin resistance, a prediabetic condition, precedes the onset of frank type 2 diabetes and offers potential avenues for early intervention to treat the disease. Although lifestyle modifications and exercise can reduce the incidence of diabetes, compliance has proved to be difficult, warranting pharmacological interventions. However, most of the currently available drugs that improve insulin sensitivity have adverse effects...

BACKGROUND: In Brazil, despite the recommendations of the Brazilian Society of Hemodynamics and Interventional Cardiology, the National Health System has not yet approved the use of drug-eluting stents. In percutaneous coronary interventions performed in the public and part of the private health care system, bare metal stents are used as the only option. Therefore, new information on bare metal stents is of great importance. The primary endpoint was to evaluate the influence of the alloy and the profile of coronary stents on late loss and restenosis rates 6 months after implantation in patients with multivessel coronary disease...

OBJECTIVE: Trivalent chromium (Cr3+) is an essential micronutrient. Findings since the 1950s suggest that Cr3+ might benefit cholesterol homeostasis. Here we present mechanistic evidence in support of this role of Cr3+. METHODS AND RESULTS: High-density lipoprotein cholesterol generation in 3T3-L1 adipocytes, which are rendered ineffective by the hyperinsulinemia that is known to accompany disorders of lipid metabolism, was corrected by Cr3+. Mechanistically, Cr3+ reversed hyperinsulinemia-induced cellular cholesterol accrual and associated defects in cholesterol transporter ATP-binding cassette transporter-A1 trafficking and apolipoprotein A1-mediated cholesterol efflux...

High-fat diet has been implicated as a major cause of insulin resistance and dyslipidemia. The objective of this study was to evaluate the impact of dietary-supplementation of chromium (D-phenylalanine)(3) [Cr(D-Phe)(3)] on glucose and insulin tolerance in high-fat diet fed mice. C57BL/6-mice were randomly assigned to orally receive vehicle or Cr(D-Phe)(3) (45 μg of elemental chromium/kg/day) for 8-weeks. High-fat-fed mice exhibited impaired whole-body-glucose and -insulin tolerance and elevated serum triglyceride levels compared to normal chow-fed mice...

Insulin resistance has been shown to be the major contributing factor to the metabolic syndrome, which comprises a cluster of risk factors for metabolic aberrations such as obesity, dyslipidemia, hypertension, and hyperglycemia. Additionally, insulin resistance has been associated with the occurrence of cardiovascular disease and type 2 diabetes. Epidemiological studies indicate that obesity and diabetes have become alarmingly prevalent in recent years. Substantial evidence suggests that dietary interventions and regular exercise greatly improve body mass index and lipid profile as well as alleviate insulin resistance...

BACKGROUND: Metabolic syndrome is a clinical disorder that is becoming more prevalent in Spain. The syndrome encompasses a set of metabolic disorders such as type-2 diabetes mellitus, hypertension, dyslipidemia, and obesity, which may be associated with variations in serum levels and poor delivery of certain mineral elements. METHODS: This study attempted to ascertain whether metabolic syndrome might be linked to alterations in serum levels of the mineral elements magnesium, copper, zinc, chromium, and nickel in a population of 92 diabetic subjects, some suffering from certain conditions associated with the metabolic syndrome, and 72 control subjects (Hospital Príncipe de Asturias, Alcalá de Henares, Spain)...

Dyslipidemia, often found in type 2 diabetes mellitus (T2DM) patients, plays an important role in the progression of cardiometabolic syndrome. Two essential nutrients, chromium and biotin, may maintain optimal glycemic control. The authors report here a randomized, double-blind placebo-controlled trial (N=348; chromium picolinate and biotin combination [CPB]: 226, placebo: 122; T2DM participants with hemoglobin A1c [HbA1c] >or=7%) evaluating the effects of CPB on lipid and lipoprotein levels. Participants were randomly assigned (2:1 ratio) to receive either CPB (600 microg chromium as chromium picolinate and 2 mg biotin) or a matching placebo once daily for 90 days...

Low-molecular weight organic chromium complexes are thought to play a key role in carbohydrate and lipid metabolism and therefore have been gaining popularity as nutritional supplement for patients with diabetes and concomitant lipid disorders. The aim of the present study was to evaluate the effects of a novel synthetic chromium (d-phenylalanine)(3) complex on insulin-sensitivity, plasma lipid-profile and oxidant stress in a mouse model of type II diabetes. Plasma glucose levels following intraperitoneal insulin-challenge (1U/kg) to obese ob/ob(+/+) mice treated with Cr(d-Phe)(3) (150 microg/kg/day for 6 weeks) were significantly lower compared to vehicle-control (control: 175...

Low-molecular-weight organic chromium complexes such as chromium picolinate are often used as dietary supplements to improve insulin sensitivity and to correct dyslipidemia. However, toxicity associated with such chromium compounds has compromised their therapeutic value. The aim of this study was to evaluate the impact of a newly synthesized complex of chromium with phenylalanine, Cr(pa)3 on insulin-signaling and glucose tolerance. Cr(pa)3 was synthesized by chelating chromium(III) with D-phenylalanine ligand in aqueous solution...

The prevalence in obesity has increased dramatically over the past 30 years, more than double in the United States alone. Obesity is associated with an increased risk for type 2 diabetes mellitus, dyslipidemia, hypertension, biliary disease, obstructive sleep apnea, and certain types of cancer. The pathophysiology of obesity is complex, involving behavioral, environmental, and genetic factors. Current treatment options include behavior modification and lifestyle changes which incorporate weight-reducing diets and physical activity, FDA approved long-term anti-obesity pharmacological agents sibutramine and orlistat, non-FDA approved over-the-counter (OTC) supplements and nutriceuticals, and, when appropriate, bariatric surgery...
