BACKGROUND The effects of intensive glucose control on cardiovascular events in patients with long-standing type 2 diabetes mellitus remain uncertain. METHODS We randomly assigned 1791 military veterans (mean age, 60.4 years) who had a suboptimal response to therapy for type 2 diabetes to receive either intensive or standard glucose control. Other(More)
BACKGROUND Impaired glucose tolerance is associated with increased rates of cardiovascular disease and conversion to type 2 diabetes mellitus. Interventions that may prevent or delay such occurrences are of great clinical importance. METHODS We conducted a randomized, double-blind, placebo-controlled study to examine whether pioglitazone can reduce the(More)
OBJECTIVE To evaluate the effect of vitamin E supplementation on the susceptibility of low-density lipoprotein (LDL) and LDL subfractions to oxidation and on protein glycation in non-insulin-dependent diabetes mellitus (NIDDM). RESEARCH DESIGN AND METHODS Twenty-one men with NIDDM (HbA1c = 6-10%), ages 50-70, were randomly assigned to either 1,600 IU/day(More)
Oxidized low-density lipoprotein (LDL) is more atherogenic than native LDL. The initial step in the oxidation is the peroxidation of polyunsaturated fatty acids. Thus, decreasing the concentration of polyunsaturated fatty acids should reduce the susceptibility of LDL to oxidation. Therefore, we tested the possibility that diets enriched in oleate might(More)
BACKGROUND Plasma C-reactive protein (CRP) concentrations are increased in obese and/or hyperinsulinemic individuals. The goal of this study was to determine if the relation between insulin resistance and CRP was independent of obesity. METHODS AND RESULTS Plasma CRP concentrations were measured before and after 3 months of calorie restriction in 38(More)
OBJECTIVE Monocyte/macrophage inflammation is an important contributor to diabetes and cardiovascular disease. Studies have suggested saturated fatty acids (SFA) induce monocyte inflammation in a Toll-like receptor-4-dependent manner, but recent data suggest SFA do not directly interact with Toll-like receptor-4. The present study tests the novel hypothesis(More)
Quantification of 8-iso-prostaglandin F(2alpha) (8-iso-PGF(2alpha)) has been suggested to be a reliable indicator of lipid peroxidation that may be related to in vivo free radical generation, oxidative damage, and antioxidant deficiency. We have developed a LC-MS/MS method to quantify 8-iso- PGF(2alpha) and its dinor metabolite,(More)
AIMS This study examined the effects of pioglitazone on body weight and bone mineral density (BMD) prospectively in patients with impaired glucose tolerance as pioglitazone (TZD) increases body weight and body fat in diabetic patients and increases the risk of bone fractures. METHODS A total of 71 men and 163 women aged 49.3 (10.7) years [mean (s.d.)];(More)
The purpose of this study was to determine the effect of exercise training on the levels of C-reactive protein (CRP) and adiponectin, and to assess whether exercise-induced changes in insulin resistance could be explained in part by changes in these inflammation markers. Study participants included 51 middle-aged (45.3+/-8.3 years; mean+/-SD), overweight(More)
Chronic sub-acute inflammation contributes to the pathogenesis of type 2 diabetes mellitus and cardiovascular disease. High doses of salicylate reduce inflammation, glucose and triacylglycerols, and may improve insulin sensitivity, suggesting therapeutic potential in impaired fasting glucose and/or impaired glucose tolerance. This trial aimed to evaluate(More)
