Usefulness of the daily defined dose method to estimate trends in the consumption, costs and prevalence of the use of home enteral nutrition.

Background & Aims: To analyse the trends in consumption and costs of home enteral nutrition (HEN) products in Andalusia (Spain) and estimate the prevalence of HEN from 2000 to 2007.

Methods: Using the defined daily dose (DDD) method, we assigned a DDD to each type of diet, grouped as whole diets, supplements, modules and thickeners. The number of cases/10(6) inhabitants/day (CID) was calculated.

Dietary alterations in plasma very low density lipoprotein levels modify renal excretion of urates in hyperuricemic-hypertriglyceridemic patients.

Hyperuricemic-hyperlipidemic patients exhibit decreased renal excretion of urates relative to purely hyperuricemic patients; also, very low density lipoprotein (VLDL) levels are inversely proportional to the amount of urate excreted. Based on this knowledge, the aim of this study was to alter VLDL levels by dietary manipulation and assess its effect on uric acid levels and renal excretion of uric acid. Thirty-six men were studied in 2 groups consisting of 20 primary hyperuricemic (group I) and 16 primary hyperuricemic-hypertriglyceridemic patients (group II).

[Lipoprotein profile in patients with isolated hyperuricemia].

There have been described abnormalities in the lipoprotein profile of hyperuricemic patients, it has not been clarified wether these abnormalities are due to the hyperuricemia or to the hyperlipidemia often associated to these patients. Our aim is to study the apolipoprotein profile in hyperuricemic patients without hyperlipidemia compared to a control population. 30 hyperuricemic patients and 26 healthy controls.
