[Preoperative nutritional assessment: a 1-year experience].

A study was made of 443 surgical patients using a standard protocol for nutritional evaluation based on anthropometrical, analytical and immunological tests. The main criteria used for considering the presence of malnutrition was a weight loss of 10% and/or seric albumin level of less than 3.5 g/dl., by which method four nutritional groups were established. The average age of the sample was 56 +/- 15 years and 35% of patients had neoplasias, 9.25% of patients were classified as belonging to Group A (weight loss and low albumin levels), 10.15% as group B (low albumin levels), 14.44% as group C (weight loss), and 66.16% as group D (normal), so that the global malnutrition percentage was 33.84%. The Body Mass Index (BMI) and Ideal Weight Percentage (% IWP) were of similar importance, and there was a significant alteration in the Triceps Skin Fold (% TSF) and Muscular Area Percentage of the arm (% MAP) when malnutrition was in evidence. In the study of the Delayed Hypersensitivity Skin Tests (DSST) 21.4% showed anergia, 15.8% hypoergia and 62.8% were reactive, with a reduction in reactivity in the case of malnutrition. This was the parameter that most affected the albumen level.

[The nutritional status and immunological situation of cancer patients].

A study was performed on the nutritional state of a sample of 138 patients with digestive and extradigestive neoplasias. The study protocol was based on anthropometric, analytical and immunological tests. The main criteria for malnutrition were as follows: loss of 10% or more in normal weight and/or albumen levels of less than 3.5 gr/dl. A global malnutrition percentage of 56.5% was obtained. The highest malnutrition percentages were found among patients with neoplasia of the oesophagus (78.9%) and the lowest in neoplasias of the breast (9.1%). From the nutritional standpoint, neoplasias of the rectum showed an extradigestive behaviour, with a low malnutrition percentage (40%) compared to digestive tumors. The global malnutrition level for the sample studied was 56.6%. The muscular compartment was the most affected in cases of malnutrition. In the PCHR results, no evidence of the effect of the nutritional state on the alteration of these was recorded (Chi 2 = 6.42, p = 0.207).

[Immunologic consequences of malnutrition: assessment with multitest].

Presentation of a clinical study of 256 patients eligible for elective surgery, with the purpose of evaluating the immunological consequences of malnutrition. With this aim, retarded hypersensitivity skin tests were performed. The malnutrition criteria used included 10% normal weight loss and/or seric albumin levels of less than 3.5 g/dl. There were 99 patients in total (38.67%) with malnutrition criteria. Within this group 21.79% showed positive responses compared to 38.88% of control group (p less than 0.001). The "average papule" in the group suffering from malnutrition was 4.18 +/- 2.06 and in the control group, 3.64 +/- 2.20 (p less than 0.001), with a significant increase in tuberculine papule in the group with malnutrition.

[Variability of anthropometric parameters].

Presentation of a comparative study of four ideal weight tables applied to the same population, in order to evaluate the differences or similarities between the same. Significant differences (p<0.001) were found between the four tables studied (WHO, USA, Barcelona, Tenerife) when classifying a patient into one of the three groups defined (malnutrition, normal and obese). The maximum differences found were between the Barcelona and Tenerife tables, which classified 13,7% and 24.05% respectively as cases of malnutrition and 35.9% and 16.89% respectively as obese.

[Incidence of malnutrition in a surgery department].

Presentation of a description of the initial results obtained in nutritional evaluation of patients admitted for elective surgery during a 6-month period. A total of 212 patients were studied, recording malnutrition in 25%. This was severe in half of the cases. As a result of the malnutrition, a significant reduction was observed in the number of positive responses to the Multitest and the total count of lymphocytes.
