Vascular calcification by conventional X-ray and mortality in a cohort of predominantly African descent hemodialysis patients.

Background/objective: There is a lack of studies describing the prevalence of vascular calcification (VC) and its association with mortality in maintenance hemodialysis (MHD) patients of African descent. We investigated if a VC score based on the number of calcified vascular beds was associated with mortality in MHD patients.

Methods: We analyzed data from 211 MHD patients enrolled from January 2010 to January 2011 in the prospective cohort study, "The Prospective Study of the Prognosis of Chronic Hemodialysis Patients (PROHEMO)," developed in Salvador, BA, Brazil.

A 3-day diary of dietary protein and calorie intake by serum phosphate concentration and binder use in hemodialysis patients.

Introduction: The use of phosphate binders to control hyperphosphatemia may allow diets less restricted in protein and calories for maintenance hemodialysis (MHD) patients. The study compared intakes of protein, calorie and phosphate among MHD patients with different serum phosphate concentrations, taking into account binder use. The hypothesis was that low serum phosphate would be associated with low intakes of protein and calories only in patients not on binders.

Associations of physical activity energy expenditure with nutritional-inflammatory markers in hemodialysis patients.

Background: Sedentariness, high inflammation status and malnutrition are highly prevalent in end-stage kidney disease patients on maintenance hemodialysis (MHD). This study investigated associations of weekly physical activity energy expenditure (PAEE) with clinical and anthropometric markers of nutrition and inflammation.

Methods: The analysis was performed using baseline cross-sectional data of 640 patients enrolled in the prospective cohort "The Prospective Study of the Prognosis of Patients Treated Chronically by Hemodialysis" (PROHEMO) developed in Salvador, BA, Brazil.

Curcuma longa as additive in the diet for Astyanax aff. bimaculatus.

The aim of the present study was to evaluate the effect of turmeric (Curcuma longa) as additive in the diet for Astyanax aff. bimaculatus. Fish (0.

Potentially modifiable factors associated with non-adherence to phosphate binder use in patients on hemodialysis.

Background: Despite the evidence that phosphate binder (PB) is associated with improved outcomes many hemodialysis patients do not adhere to prescribed PB regimen. Therefore, barriers to PB adherence should be identified and eliminated. The purpose of this study was to evaluate PB adherence among hemodialysis patients and to explore potentially modifiable factors associated with low PB adherence.

Handgrip strength as a simple indicator of possible malnutrition and inflammation in men and women on maintenance hemodialysis.

Objective: To assess the validity of handgrip strength (HGS) as a simple screening instrument for malnutrition and inflammation in patients on maintenance hemodialysis (MHD) by correlating it with malnutrition-inflammation score (MIS).

Design: Cross-sectional analysis of the Prospective Study of the Prognosis in Chronic Hemodialysis Patients (PROHEMO).

Setting: Satellite dialysis units in the city of Salvador, Brazil.

Depression as a potential explanation for gender differences in health-related quality of life among patients on maintenance hemodialysis.

Background/aims: The reasons for lower health-related quality of life (HRQOL) scores in women compared to men on maintenance hemodialysis (MHD) are unknown. We investigated whether depression accounts for gender differences in HRQOL.

Methods: Cross-sectional study of 868 (40.

[Prescription of phosphorus binders and calcitriol for chronic hemodialysis patients].

Objective: To describe the frequency of prescription of phosphate binders (PB) and calcitriol for patients on chronic hemodialysis in Salvador, Brazil, and to assess whether treatment is in agreement with recommendations of the Kidney Disease Outcomes Quality Initiative (K/DOQI).

Methods: Cross section of baseline data of the PROHEMO study. The frequency of prescription of PB and calcitriol according to laboratory indicators of mineral metabolism was compared with K/DOQI recommendations.

[Comparisons of quality of life measures between women and men on hemodialysis].

Objective: To compare men and women on chronic hemodialysis in relation to their scores in health-related quality of life (HRQOL) and evaluate the potential influence of age and comorbidities on the comparison.

Methods: Cross-section of the baseline data of 254 women and 349 men, participants of the PROHEMO Study that has been developed in dialysis units of Salvador. By using the version of the Kidney Disease Quality of Life Short Form KDQOL-SF, validated for the Brazilian population, the following scores were determined: physical component summary (PCS), mental component summary [MCS] and the scale for symptoms/problems related to renal disease.
