[Nutritional support in the patient with GI malignancy].

Hyponutrition is a common feature of patients with GI malignancy. When these patients reach a critical situation, such as the postoperative period of a tumor resection or after a surgery for the presence of complications, nutritional status further deteriorates. Nutritional intervention should be part of the therapeutic process, starting at the preoperative phase in malnourished patients. Enteral nutrition is the route of choice for nutrients supply, although insertion of enteral tubes during the surgical procedure may need to be considered many times. Enteral nutrition is a safe technique in these patients and may even represent some advantages in their clinical course as compared to parenteral nutrition. The use of pharmaco-nutrients-enriched diets brings beneficial effects (decrease of infectious complications and hospital stay) to patients, although a favorable effect on mortality cannot be demonstrated.

[Nutritional support in aids patients].

Advances in HIV infected patients' treatment have modified their prognosis, making possible to consider their admission to the ICU for acute complications. HIV infected patients show nutritional impairments onto which changes due to acute disease are added. Thus, they are candidate to receive specialized nutritional support. The enteral route should be preferred for nutrients supply in case of necessary. With regards to nutritional support characteristics, it should be adapted to the metabolic situation, similarly to what is recommended for other diseases. It has not been demonstrated that the use of substrates with a pharmaco-nutrient capability (glutamine or arginine supplements or modifications in the lipidic component quality) will improve the immunological condition or the clinical curse of patients with HIV infection/AIDS.

[Nutritional status of an hospitalised aged population].

AIMS: The aims of the study were to evaluate the nutritional status of the hospitalised elderly patients, to estimate the prevalence and distribution of malnutrition among them and to value the correlation of the Mini Nutritional Assessment (MNA) with nutritional biochemical and anthropometric parameters. MATERIAL AND METHODS: A cross sectional survey was done among a sample of 200 elderly patients admitted to the USP San Carlos Hospital (Murcia) during a period of 3 months. The study employed the MNA and a blood test including hemogram and albumin and transferrin serum levels. Chang's protocol was used to classify the nourishing pattern. For statistical analyses of the MNA tool, the Spearman's coefficient was employed. RESULT: Mean age of the 200 patients was 80.72 SD 7.43 years. Mean weight was 63.41 SD 19.57 kg and mean height was 160.93 SD 8.36 cm, with a mean Body Mass Index of 24.27 SD 7.31. The serum values of albumin and transferrin and total lymphocytes in blood were 3.09 SD 0.5 g/l, 1.69 SD 0.37 mg/dl and 1412 mm3 respectively. Average score of the MNA was 15.9 SD 6.21 with a maximum value of 27 and a minimum of 5.5 points. According to this scale, 50% (n=100) of the patients were malnourished, and 32% (n=32) of them presented mixed undernutrition of moderate degree. Values of malnutrition in the MNA test correlated significantly (p < 0.001) with values under normality of the biochemical and immunological parameters. CONCLUSIONS: Patients over 80 years of age are either malnourished or at risk of malnutrition. These results are obtained both by means of the nutritional classic valuation and the MNA and presents a statistically significantly correlation. Therefore the MNA represents a useful, reliable and easily administered clinical tool to identify elderly people at risk of malnutrition and guide nutritional intervention in order to improve nutritional status.
