As life expectancy increases, so do the problems of the elderly population. One major problem is that of protein calorie malnutrition; another is the susceptibility of this population to pressure sores. The purpose of this study was to determine if a correlation exists between deteriorating nutritional status and the development of pressure sores. The nutritional status of 232 nursing home patients (mean age 72.9 +/- 12 years) was determined using biochemical and anthropometric measurements. Overall, the incidence of some degree of malnutrition was 59%. Seventeen of the patients were found to have pressure sores and were all malnourished. When classified as mild, moderate, or severe malnutrition, the patients with pressure sores were in the severe group. There was a significant difference (P less than .001) between the nutritional status of pressure sore patients and the malnourished patients. It appears that the development of pressure sores correlates with nutritional deficiencies. The authors' findings suggest a need for more aggressive nutritional support in the elderly, especially those with pressure sores.

That nutritional parameters change with age is a well-known phenomenon. Physical activity, lean body mass, and metabolic rate all decline with increasing age. There has been little work regarding the nutritional assessment of geriatric nursing home patients to determine their nutritional status and to focus attention on their nutritional needs. The purpose of this study was to assess the nutritional status of the residents of two urban nursing homes. The nutritional status of 227 nursing home residents (mean age 72.2 years) was evaluated using biochemical and anthropometric measurements. Midarm muscle circumference, triceps skinfold thickness, weight, height, serum albumin, serum pre-albumin, serum retinol binding protein, and a complete blood count with differential were obtained. The evaluation of this data indicated that there was a 52% incidence of malnutrition. This can be broken down to: 24% hypoalbuminemic malnutrition, 19% Kwashiokor-Marasmus mix, and 9% Marasmus. Twenty-eight percent of all patients were anergic, and 76% of the patients were anemic. In conclusion, there appears to be far more documentable malnutrition than anticipated or previously reported in this population.

A guide to the steps in the wound-healing response and to the role of nutrients in this process.

Periodic parenteral hyperalimentation, the interruption of feeding for a period of time each day, parallels the fasted vs fed state in the meal eater. The fasted state appears to be more physiologic and seems to be associated with an increase of visceral proteins. Intravenous hyperalimentation data that have been published seem to confirm this fact. The purpose of this study was to compare the effect of continuous enteral hyperalimentation and interrupt enteral hyperalimentation on the visceral protein compartment. Two groups of 10 afebrile matched control patients (group 1) were on continuous enteral hyperalimentation for 19 +/- 6 days with no improvement in serum albumin or serum transferrin levels. No changes were made in the feeding schedules of 10 of the patients. Feeding schedules of the other 10 patients were changed to an 8-hr interrupt enteral hyperalimentation with calories, protein, and volume being provided remaining the same. Repeat serum albumin and transferrin levels were obtained after 10 days. There was a significant increase in albumin and transferrin levels (p less than 0.005) in those patients changed to an interrupt feeding schedule.
