BACKGROUND AND OBJECTIVES Peritonitis remains as the most frequent cause of peritoneal dialysis (PD) failure, impairing patient's outcome. No large multicenter study has addressed socioeconomic, educational, and geographic issues as peritonitis risk factors in countries with a large geographic area and diverse socioeconomic conditions, such as Brazil.

BACKGROUND In some parts of the world, peritoneal dialysis is widely used for renal replacement therapy (RRT) in acute kidney injury (AKI), despite concerns about its inadequacy. It has been replaced in recent years by hemodialysis and, most recently, by continuous venovenous therapies. We performed a prospective study to determine the effect of continuous(More)
INTRODUCTION Some studies suggest that high body mass index (BMI) confers survival advantage in dialysis patients, but BMI does not differentiate muscle from fat mass, and the survival advantage conferred by its increase seems to be limited to patients with high muscle mass. Thus, discriminating body components when evaluating nutritional status and(More)
OBJECTIVES There is recent evidence that aldosterone play a role in the pathogenesis of cardiovascular disease in dialysis patients, which leads to the opportunity to block its actions for the benefit of these patients. In nondialytic chronic kidney disease, spironolactone was safe and effective in reducing left ventricular hypertrophy. However, routine use(More)
OBJECTIVE To evaluate the systemic blood pressure (BP) during daytime and nighttime in children with sleep breathing disorders (SBD) and compare parameters of BP in children with diagnosis of obstructive sleep apnea syndrome (OSA) to those one with primary snoring (PS). METHODS Children, both genders, aged from 8 to 12 years, with symptoms of SBD realized(More)
BACKGROUND AND PURPOSE The evidence of the benefits from regular physical activity to hypertensives is based on dry land training studies. Therefore, the aim of this study is to compare the effect of aquatic exercise with dry land training on hypertensive women. METHODS This is a randomized controlled study with 52 post-menopausal hypertensive women. The(More)
Malnutrition is a strong predictor of mortality in hemodialysis patients. Several scoring systems for evaluating nutritional status have been proposed. However, they rely on different sets of anthropometric and laboratory markers to make a diagnosis of malnutrition and assess its impact on prognosis. To validate them, nutritional scores should be compared(More)
Accumulating evidence suggests an association between body volume overload and inflammation in chronic kidney diseases. The purpose of this study was to evaluate the effect of dialysate sodium concentration reduction on extracellular water volume, blood pressure (BP), and inflammatory state in hemodialysis (HD) patients. In this prospective controlled(More)
BACKGROUND Left ventricular hypertrophy (LVH) is a well-known predictor of cardiovascular mortality in patients who have end-stage renal disease and are maintained on hemodialysis (HD), and LVH is not always correlated with the severity of hypertension in these patients. The purpose of this study was to investigate the role of other factors contributing to(More)
The purpose of this study is to evaluate associations between clinical, laboratory, demographic, and nutritional markers with inflammatory state and malnutrition in hemodialysis (HD) patients. Fifty-two patients on regular HD were evaluated by clinical, demographic, laboratory, and nutritional parameters (food intake, anthropometric measurements,(More)
