This review focuses on the role of oxidative processes in atherosclerosis and the cardiovascular diseases (CVD) that can arise as a result. Atherosclerosis represents a state of heightened oxidative stress characterized by lipid and protein oxidation in the vascular wall. Overproduction of reactive oxygen species (ROS) under pathophysiologic conditions(More)
Plasma viscosity (PV) and blood viscosity (BV) have been scarcely evaluated in morbid obese patients with no other concomitant cardiovascular risk factors. Contradictory results have been published regarding the influence of insulin resistance on these rheological parameters in obesity. In 67 severe or morbid obese patients without other cardiovascular risk(More)
Retinol binding protein 4 (RBP4) is an adipokine that may contribute to the development of insulin resistance. However, how this adipokine is affected and its possible involvement in lipid metabolism in obese patients with varying degrees of insulin resistance is yet to be determined. A total of 299 middle-aged morbid obese patients (BMI>40 kg/m(2)) were(More)
INTRODUCTION An association between an increase in plasminogen activator inhibitor type 1 and obesity has been described. It has also been shown that a decrease in adiposity has beneficial effects. However, less information is available regarding morbid obesity and hypofibrinolysis. The aim of the present study was to evaluate the effect of weight loss and(More)
There is a predominance of small and dense LDL cholesterol particles in familial combined hyperlipidemia (FCH). The lipoprotein lipase gene could exert an influence in these circumstances.To study the relationship of pattern B LDL and lipids with N291S polymorphism of lipoprotein lipase (LPL) in FCH patients.Lipid profile, apolipoproteins, diameter of LDL(More)
A patient with severe vomiting following gastric banding developed Wernicke's encephalopathy. All neurological disorders disappeared with thiamine treatment. This complication may be prevented by keen awareness, early diagnosis and treatment, in patients with persistent vomiting. Vitamin and mineral supplementation must be taken in patients following(More)
BACKGROUND Obesity has been associated with a chronic activation of the acute-phase response. The aims of our study were to investigate whether levels of inflammatory cytokines are higher in obese patients, to evaluate their relationship with metabolic syndrome, and to analyze the effect of moderate weight loss upon their levels. METHODS Sixty-seven(More)
The association between morbid obesity and hyperhomocysteinemia (HH) remains controversial and the nature of this relationship needs to be clarified as several metabolic, lipidic, inflammatory and anthropometric alterations that accompany morbid obesity may be involved. In 66 morbidly obese patients, 47 women and 19 men aged 41 ± 12 years and 66(More)
Although there are several studies dealing with erythrocyte deformability (ED) in obese patients, research on this topic in morbidly obese subjects is scarce. In these studies ED seems to be decreased, although the cause remains unknown. A case-control study in 76 morbid obese subjects (23 women and 53 men, aged 44 ± 13 years) and in 79 normal-weight(More)
OBJECTIVE To compare erythrocyte aggregation (EA) in patients with severe obesity without other cardiovascular risk factors with a control group, using the Myrenne and the Sefam aggregometers, and to evaluate the effect of weight loss on this parameter. RESEARCH METHODS AND PROCEDURES This was a longitudinal, clinical intervention study of a very(More)
