BACKGROUND Morbid obesity (MO) is associated with increased renal plasma flow (RPL) and glomerular filtration rate (GFR). This type of obesity usually does not respond to medical treatment, with bariatric surgery being the current treatment of choice. The present study aimed to evaluate whether weight loss may reverse the glomerular hyperfiltration of MO(More)
CONTEXT Causal factors of gastrojejunal ulcers after Roux-en-Y gastric bypass include peptic acid secretion from the gastric pouch. Esomeprazole is a potent inhibitor of acid secretion. OBJECTIVE To assess the occurrence of dyspepsia and gastrojejunal ulcers within the first 2 months after Roux-en-Y gastric bypass during the use of esomeprazole. METHODS(More)
BACKGROUND The metabolic syndrome (MS) is a complex disorder characterized by a number of cardiovascular risk factors usually associated with central fat deposition and insulin resistance. Many different medical treatments are available for MS, including bariatric surgery, which improves all risk factors. The present study aimed to evaluate, at the Clinic(More)
OBJECTIVE The purpose of the study was to investigate the prevalence of hyperuricemia in morbidly obese subjects before and after Roux-en-Y gastric bypass (RYGBP) and its relationship with metabolic syndrome abnormalities. SUBJECTS AND METHOD We evaluated 420 morbidly obese patients. Pre and postoperative (8 months after RYGBP) blood samples were drawn.(More)
BACKGROUND Metabolic Syndrome (MS) is a complex disorder characterized by a number of cardiovascular risk factors usually associated with central fat deposition and insulin resistance. Nowadays, there are many different medical treatments to MS, including bariatric surgery, which improves all risk factors. The present study aims to evaluate the influence of(More)
OBJECTIVES To evaluate whether biochemical parameters are associated with a good glycemic control and to identify the occurrence of cardiometabolic risk variables. MATERIAL AND METHODS One hundred forty Brazilians were evaluated. The subjects were characterized with regard to glycemic control as good, fair and poor and were divided into tertiles by TG and(More)
OBJECTIVES To evaluate the relations between liver markers (GGT, ALT and AST) and the metabolic syndrome (and its components) in morbidly obese subjects, and to determine the response of these metabolic factors and hepatic enzymes after weight loss induced by Roux-en-Y gastric bypass. METHODS This study was carried out at a university hospital, in Santo(More)
Obesity was initially regarded as a psychosocial disorder, but, after years of study, has come to be understood as a chronic disease for which there is no cure, like hypertension and diabetes6,7. Surgical intervention is safe and effective in the long term and aims to control the disease and its comorbidities. Even so, it is hoped that the proportion of(More)

OBJECTIVE Considering that the Cockcroft-Gault formula and the equation of diet modification in renal disease are amply used in clinical practice to estimate the glomerular filtration rate, although they seem to have low accuracy in obese patients, the present study intends to evaluate the predictive performance of 12 equations used to estimate the(More)
