[How valid are food surveys run by dieticians?].

International recommendations for dialysis treatment include food surveys among the necessary tools for nutritional status evaluation. Several methods are used: 24-hour food recall, 7-day food diary, 3-day food record, food frequency questionnaire, and the most innovative, pictures of the ingested food shot and sent to the dietician with a mobile phone. The information from these surveys is run on software that calculates the amount of ingested nutriments.

The plasma level of brain natriuretic peptide is increased in malnourished hemodialysis patients.

Background: In hemodialysis (HD) patients, the plasma brain natriuretic peptide (BNP) level is associated with left ventricular dysfunction and patients' survival. Malnutrition is common in HD patients, it is associated with inflammation and contributes to the high incidence of cardiovascular (CV) disease in this setting (malnutrition-inflammation-atherosclerosis syndrome). In a cross-sectional study, we assessed the relationship between predialysis plasma BNP level and nutritional markers in chronic HD patients.
