Surgery in the elderly is not a challenge anymore. Yet, malnutrition stays one of the principal adverse factors in surgery, particularly in the aged. In ten months, 250 patients aged 65 years or older (mean: 75) have been operated in our general surgery department, with 25% of major complications and a mortality 3.6%. Nutritional state was evaluated on a clinical basis and by measurement of the serum albumin level. In case of malnutrition, morbidity was multiplied by 2, mortality by 3. These results emphasize the necessity for identification of this high risk population and the need to correct their nutritional state preoperatively by hyperalimentation.

1. The effects of streptozotocin-diabetes, bulk-diet, low protein diet (8%) and protein-calorie malnutrition on parotid gland response to sympathetic nerve stimulation were studied in male Wistar rats. 2. Mean body weights were considerably less in diabetic and protein-calorie malnourished rats than in the other groups, but parotid gland weight was reduced only in animals placed on a low-protein diet. 3. Salivary flow rate (microliter/min/g tissue) and total protein output (mg secreted/g tissue) were reduced in diabetic rats. 4. Salivary composition was altered in diabetes and protein-calorie restriction, and the specific changes were unique to each condition. 5. Thus, with the possible exception of gland weight the effects of diabetes on parotid gland structure and function are not related to either hyperphagia or nutritional status.

Little is known about effective treatment for severe diarrhea in the insulin-dependent diabetic patient. A 41-year-old woman was admitted to our hospital because of hyperglycemia and dysuria. She had stopped insulin self-injection therapy for 2 years and diarrhea had become worse, resulting in malnutrition. Following enteral alimentation by elemental diet (ED) with continuous subcutaneous insulin infusion (CSII), frequency of diarrhea remarkably decreased and general nutritional condition was improved. At the first step, the patient was given 600 kcal/d ED through the tube sustained in the jejunum. Total calorie intake for 24 hours was gradually increased to the level of 2400 kcal/d and this therapy continued for 5 months. During this period, blood glucose level was kept in almost normal range (between 100 and 200 mg/dL) through the continuous insulin infusion of regular insulin (1.0-1.5 U/h). Thereafter, general conditions were improved and frequency of diarrhea gradually decreased. When this treatment was stopped, watery diarrhea, steatorrhea, and hypoalbuminemia completely disappeared and she gained 12 kg of body weight. Furthermore, spontaneous urination appeared following this treatment. This case suggests that the enteral hyperalimentation combined with strict control of blood glucose, using the CSII, may be an effective therapy for such severe diarrhea with malnutrition in diabetes.

Psychogenic influences on the immune system become evident via the nervous system, particularly in its paraspecific part and the parameters there of. On the one hand the sifting and systematization of the investigations carried out so far forces criticism and evaluation of methods, shows on the other hand however a number of important findings and conclusions, which can be deduced from this knowledge. (1) Immunosuppressive effects have to a great extent their roots in psycho-social influences, leading to an overtaxing of the human capacity to adapt; occupational stress, depression, helplessness, loneliness, hopelessness, lack of social support, suppression of emotional disturbance and aggression, psychological vulnerability, etc. (2) A psychogenic stimulation of the immune system is founded in certain personality traits (self-confidence, openness, etc.) and a life-style, which is characterized by security and support in the social sphere, by the ability to handle one's illness positively, by recognizing effective forms of coping with stress, as well as trust and faith in realizing the unlikely and a will to survive based on self-discipline. (3) Forms of hyperalimentation, malnutrition and wrong eating habits result in immunosuppressive effects and, in highly developed industrial countries, have their roots in stress situations, which cannot be coped with (e.g. stress due to separation from partner, stress connected with divorce, occupational stress, loneliness, helplessness, lack of social support, suppression of emotional disturbance and aggression, sleep deprivation, immobilization, etc.) and are therefore founded in variables of life-style and biography.

Nutrition is one of the most important factors affecting wound healing. Patients who have significant protein malnutrition and require emergency surgery are frequently encountered. Conventional nutritional preparation for surgery, with intravenous hyperalimentation, requires 10 to 14 days to demonstrate advantageous reversal of catabolism. Growth hormone is known to have an anabolic effect in malnourished animals. The purpose of this investigation was to study the ability of growth hormone, administered from the time of celiotomy, to improve wound strength in protein-malnourished animals and compare its efficacy with preoperative nutritional repletion. Rats were divided into four groups: Group I--normal control rats, group II--malnourished rats, group III--malnourished rats treated with growth hormone for 5 postoperative days, and group IV--malnourished rats refed normal chow for 3 days before operation. Controlled laparotomy wounds were closed with monofilament nylon which was removed at the time wound bursting strength was tested. Bursting strengths at the sixth day postoperative were as follows (means +/- SD): (table; see text) Wound strength of malnourished animals was significantly less than that of controls, (P less than 0.001). Wound bursting strength of groups III and IV was significantly improved over that of malnourished animals (group II), P less than 0.001. The bursting strength of group IV was significantly higher than that of group III. Growth hormone administration following celiotomy is nearly as effective in improving wound healing as preoperative nutritional repletion. These results suggest that growth hormone may be clinically applicable in preventing wound complications in malnourished patients requiring urgent or emergency laparotomy.

Using the official data of WHO statistics, the impact of some social, biological and medical factors on infant mortality rates (IMR) was compared for countries with very high, high, moderate and low IMR: Factors reflecting a low quality of life (illiteracy, low level of women's education, low urbanization, malnutrition etc.) showed a highly significant statistic correlation with increased IMR. The lack of a nationwide family planning program and a low level of medical care (prenatal care, presence of medical personnel during delivery, availability of contraceptives etc.) act in the same direction. In developing countries the GNP per capita did not markedly influence the IMR nor the rate of infants of low birth weight (UGR). One of the main reasons of this phenomenon is probably the wide gap of the income between different social groups in these countries. In contrast to this the GNP in economically developed countries (Europe, Australia, North America) correlates very closely with IMR and UGR. The impact of family planning differs between countries with legally artificial abortion and those with a more restrictive legislation. The nutritional status (i. e. in these countries hyperalimentation) shows a positive correlation with UGR but no impact on IMR. Some countries (in Europe Greece, Spain, Ireland/Yugoslavia, Romania) show a significant deviation (positive/negative) from the mean calculated according to the WHO data. These deviations can be (and should be) analysed for detecting and evaluating factors which could be influenced by strategies of social or/and medical interventions in order of further improvement of IMR.

Patient L.A. (f., 20 yrs), affected by bulimia and self-induced vomiting, was hospitalized because of severe malnutrition (BMI 13.1), hypopotassemia (2.8 mEq/l) and prolonged QTc interval (0.469"). Intensive care treatment aimed to normalize mineral balance mainly serum potassium, consisted of administering e.v. potassium (mg 2346/day), magnesium (mg 72/day), calcium (mg 80/day), phosphorus (mg 769/day), chloride (mg 710/day), iron (mg 40/day). Dietary treatment was deliberately chosen to be slightly above minimum energy requirements in order to avoid possible side effects of forced hyperalimentation. The patient, immediately after hospitalization, interrupted vomiting and 2 wks later weight increased by 5 kg (from 34.9 kg to 40.0 kg). On the other hand normalization of serum potassium levels was slow and QTc interval reached normal range only after the 10th day of treatment (0.447"). This case supports the hypothesis that major ECG abnormalities may be present in severe malnutrition due to anorexia nervosa or bulimia with self-induced vomiting. The dangers of these complications were substantiated by the fact that intensive care treatment allowed prompt body weight recovery but normalization of electrolytic balance and cardiac function was very slow. For such patients, electrocardiographic monitoring should be routine.

Fifteen patients with severe scleroderma bowel disease began receiving home central venous hyperalimentation (HCVH) between 1979 and 1987. The major reasons for instituting HCVH were intestinal pseudo-obstruction, malabsorption, and malnutrition. Eleven patients had an improved quality of life. Serious complications encountered over these 15,700 catheter-use days were 2 episodes of septicemia and 2 episodes of superior vena cava obstruction. Seven patients died, but none directly from their gastrointestinal disease or from the HCVH.

Diet therapy is an important factor in overall care of most GI patients. Historically, diets have been used unscientifically in many of these patients without positive results. Nutritional care and diet therapy are critical for two reasons. First, malnutrition is an expected sequelae to most, if not all, GI diseases or disorders. Failure to eat, digest, or assimilate nutrients can provoke malnutrition in just a few weeks, although careful assessment of anthropometric, clinical, biochemical, and nutritional history by a trained professional can protect against this. Diet therapy through the elimination of offending foods such as wheat gluten or lactose, or inclusion of specialized products such as medium chain triglycerides or elemental formulas, can sustain nutritional status. Dietary components such as insoluble fiber appear to have physiologic effects, while soluble fibers may have metabolic effects important to diabetes and cardiovascular disease. There is a high potential for malnutrition in Crohn's disease during active and remittent phases. Elemental enteral formulas or TPN are used during the active phase to ensure optimal nutritional status and bowel rest. Hyperalimentation using the GI tract during remittent stage maintains this. Avoiding offending foods by Crohn's patients is an acceptable practice as long as entire categories of foods are not deleted. Avoiding all foods containing gluten from wheat, rye, barley, and oats, however, is a crucial prerequisite to recovery from celiac disease. Gluten is commonly used as a stabilizer, emulsifier, and extender in the food industry and is not always shown on food labels. Careful consultation with a registered dietitian can identify hidden sources of gluten in the diet.(ABSTRACT TRUNCATED AT 250 WORDS)

Anorexia nervosa is a common psychiatric disorder predominantly affecting young women, associated with significant morbidity and mortality, much involving the cardiovascular system. In contrast, protein-calorie malnutrition, while not strictly analogous to the protein-sparing characteristics often noted in anorexia nervosa, is a problem of global stature. Physiologic consequences of anorexia nervosa include rhythm disturbances, mitral valve prolapse, plus both systolic and diastolic ventricular dysfunction. Diminished exercise capacity occurs in both states, with marked blunting of the heart rate and blood pressure response. Congestive heart failure may appear, especially during refeeding. In addition to the myofibrillar destruction associated with protein-calorie malnutrition, hypophosphatemia, particularly when exacerbated by unrestricted glucose-rich refeedings or hyperalimentation, may be one additional cause of ventricular dysfunction. A high level of suspicion for cardiovascular complications is, therefore, warranted in the evaluation and therapy of weight loss conditions such as starvation and anorexia nervosa.
