Prevalence of malnutrition and its etiological factors in hospitals.

Background: Malnutrition among inpatients is highly prevalent, and has a negative impact on their clinical outcome. The Working Group for the Study of Malnutrition in Hospitals in Catalonia was created to generate consensus guidelines for the prevention and/or treatment of malnutrition in hospitals in Catalonia, Spain.

Aims: The objectives of the study were to determine the prevalence of malnutrition on admission to hospital in Catalonia and to assess relationships between malnutrition, social and demographic data, overall costs, and mortality.

A lesser postprandial suppression of plasma ghrelin in Prader-Willi syndrome is associated with low fasting and a blunted postprandial PYY response.

Objective: Ghrelin and polipeptide YY (PYY) are involved in the regulation of food intake. We evaluated these two peptides and their possible relationship in adult patients with Prader-Willi syndrome (PWS).

Patients: Seven patients with PWS, 16 age-sex-BMI matched obese and 42 age-sex matched lean subjects.

Glycemic and lipid control in hospitalized type 2 diabetic patients: evaluation of 2 enteral nutrition formulas (low carbohydrate-high monounsaturated fat vs high carbohydrate).

Background: Type 2 diabetic patients may need enteral nutrition support as part of their treatment. The objective was to compare glycemic and lipid control in hospitalized patients with type 2 diabetes requiring feeding via nasogastric tube using enteral feedings with either a highcarbohydrate or a high-monounsaturated-fat content.

Methods: This trial included type 2 diabetes patients admitted to the hospital for neurologic disorders or head and neck cancer surgery who received either a low-carbohydrate-high-mono-unsaturated-fat (Glucerna) or a high-carbohydrate diet (Precitene Diabet).
