Dietary evaluation of sodium intake in patients with chronic kidney disease.

Introduction: high sodium intake is a risk factor for diseases such as systemic arterial hypertension, stroke, left ventricular hypertrophy, and chronic kidney disease (CKD). Objective: to evaluate the correlation between estimated sodium intake by dietary intake and 24-hour urinary excretion in patients with non-dialysis CKD. Material and Methods: a cross-sectional study with 151 individuals.

Sum of skinfolds measurement can be used in the estimation of total body fat in patients with chronic kidney disease undergoing hemodialysis.

Introduction: body fat reflects important clinical impacts among hemodialysis patients; thus, simple and safe methods are required for a careful evaluation of this body compartment. Objectives: to evaluate the concordance of estimates of total body fat percentage (%BF), calculated using bioelectrical impedance analysis (BIA) and sum of four skinfolds (SSKD) measures, with those obtained using dual-energy X-ray absorptiometry (DEXA) in patients with chronic kidney disease (CKD) receiving hemodialysis. Methods: a cross-sectional study was conducted in 317 patients undergoing hemodialysis.

Correlation Between Parathyroid Hormone Levels with Urinary Magnesium Excretion in Patients with Non-Dialysis Dependent Chronic Kidney Disease.

Background: Disorders of mineral metabolism occur in most patients with chronic kidney disease (CKD). The aim of this work was to correlate parathyroid hormone (PTH) levels with urinary magnesium excretion in patients with non-dialysis dependent CKD.

Methods: Cross-sectional study.

Erythropoietin Resistance in Patients with Chronic Kidney Disease: Current Perspectives.

Anemia is a frequent complication of chronic kidney disease, and its primary cause is erythropoietin deficiency. After diagnosis, treatment begins with administration of an erythropoiesis-stimulating agent (ESA). However, some patients present with resistance to ESA, which needs to be reversed, as it can increase the risk of death in patients with kidney disease.

Prevalence of sarcopenia in kidney transplants and their association with determinant factors of muscle homeostasis.

Introduction: Sarcopenia is characterized by the involuntary loss of lean body mass associated with a progressive reduction of muscle strength.

Objective: To determine the prevalence of sarcopenia in kidney transplant recipients and its association with the determining factors that control muscle homeostasis.

Methods: We evaluated renal transplant recipients undergoing follow-up at the University Hospital of the Federal University of Maranhão from June 2017 to July 2018 and who met the inclusion criteria.

Association between renal damage markers and carotid atherosclerosis in Afro-descendants with hypertension belonging to a minority ethnic group from Brazil.

Ethnicity appears to play an important role in the prevalence and severity of hypertension, renal disease, and atherosclerosis. A cross-sectional study was conducted, including 206 Afro-descendants with hypertension, living in the remaining quilombo communities. These subjects underwent a carotid intima-media thickness (CIMT) assessment.

Abdominal obesity and reduction of glomerular filtration.

The objective was to evaluate the association between nutritional status and the glomerular filtration rate (GFR) in remaining quilombolas. Cross-sectional study carried out on 32 remaining quilombola communities in the municipality of Alcântara-MA. The nutritional indicators (IN) used were: body mass index (BMI); Waist circumference (WC); Waist-to-hip ratio (WHR); Waist-to-height ratio (WHtR); conicity index (CI) and estimated visceral adipose tissue (VAT).
