Summary of "Mini nutritional assessment (MNA) as nutrition screening tool in internal medicine. Advantages and disadvantages."

To evaluate the nutritional status of the elderly hospitalized patient with the Mini Nutritional Assessment (MNA), its relationship with length of hospital stay and mortality, the incidence of malnutrition during hospitalization and to evaluate the applicability of MNA in an Internal Medicine Department of an acute care hospital. MATERIAL AND
A prospective study on the nutritional status of patients of 65 years or older admitted to hospital in an Internal Medicine Department was performed in 106 consecutive patients. In all patients a MNA test, an anthropometric (weight, height, body mass index, skinfold), and biochemical (cholesterol, lymphocytes, albumin) evaluation were performed; outcome, age, institutionalization, Charlson index and Barthel index were recorded.
Mean age of the patients was 81±7 years, Charlson index 2.3±1.9 and Barthel index 74.9±30.8. Mean weight was 64.5±10.6kg, BMI 26±3.9, and weight loss in the previous 3 months 1.17±2.92kg. Mean length of hospital stay was 11.1±9.8, and mortality was 5.7%. Prevalence of malnutrition, assessed by MNA, was 4.7%, and 36.8% of the patients were at risk of malnutrition. Malnourished patients have a longer length of hospital stay, higher Barthel and Charlson indexes. There are no conclusive differences in mortality. Incidence of malnutrition during hospitalization was between 2.43 and 15.68%.
Malnutrition increases length of hospital stay, rate of complications and costs. The clinicians responsible for the patient should perform nutrition evaluation at hospital admission and repeat it during the hospitalization, using simple screening tools that incorporate an explicit nutrition intervention plan.

Medical and Biotech [MESH] Definitions

Evaluation and measurement of nutritional variables in order to assess the level of nutrition or the NUTRITIONAL STATUS of the individual. NUTRITION SURVEYS may be used in making the assessment.

A systematic collection of factual data pertaining to the nutritional status of a human population within a given geographic area. Data from these surveys are used in preparing NUTRITION ASSESSMENTS.

The identification of selected parameters in newborn infants by various tests, examinations, or other procedures. Screening may be performed by clinical or laboratory measures. A screening test is designed to sort out healthy neonates (INFANT, NEWBORN) from those not well, but the screening test is not intended as a diagnostic device, rather instead as epidemiologic.

Nutrition of FEMALE during PREGNANCY.

The internal fragments of precursor proteins (INternal proTEINS) that are autocatalytically removed by PROTEIN SPLICING. The flanking fragments (EXTEINS) are ligated forming mature proteins. The nucleic acid sequences coding for inteins are considered to be MOBILE GENETIC ELEMENTS. Inteins are composed of self-splicing domains and an endonuclease domain which plays a role in the spread of the intein's genomic sequence. Mini-inteins are composed of the self-splicing domains only.
