An experimental protein-calorie malnutrition was produced in weanling Sprague-Dawley rats. The model resembles human malnutrition with respect to weight loss, inanition, angular stomatitis, anemia, lymphopenia, hypoproteinemia with hypoalbuminemia, and marked thymic involution. In addition, systemic invasion by gram-negative rods was documented. However, no edema was produced, and animals did not survive for longer than six weeks on the protein-deficient diet. One percent glycogen was found to be a satisfactory nonprotein stimulus for induction of a peritoneal exudate consisting primarily of young macrophages. Electron microscopy showed that morphologic events of phagocytosis and degranulation proceeded normally in macrophages from protein-deficient animals. In addition, cell surface receptors for IgG were preserved under these experimental conditions. These data indicate that weanling rats may be employed as a small animal model for servere, fulminant protein-calorie malnutrition in humans.

Interferon production by leukocytes in culture was investigated in nine severely marasmic infants and 31 well-nourished controls. The production of interferon was induced with Newcastle disease virus and assayed in Vero cells challenged with vesicular stomatitis virus. Marasmic infants produced significantly less interferon than controls. It is suggested that the finding may be the result of a lymphocyte defect induced by malnutrition and could help to explain the increased frequency and severity of viral diseases in this condition.

The objective of this study was to determine the prevalence of clinical signs of malnutrition, and to measure the interrelationship with socioeconomic, anthropometric, dietetic and educational achievement parameters. A random sample of 550 Chilean elementary and high school graduates (1:1), of both sexes (1:1), from public and private schools (1:1) and from high, medium and low socioeconomic status (SES) (1:1:1), was chosen in the Metropolitan Area of Santiago, Chile. SES was measured through the Graffar Modified Scale. Clinical signs of malnutrition were assessed according to Jelliffe. Nutritional status was determined by means of anthropometric measurements: percentages of weight/age (W/A), height/age (H/A) and weight for height (W/H) were compared with the WHO Tables; head circumference/age (HC/A) with the Tanner Tables, and branchial anthropometric parameters by applying the Frisancho norms. Standard procedures for the 24 hour dietary recall interviews were used to collect data, and adequacy of intake was assessed by the FAO/WHO pattern. Educational achievement (EA) was measured through the Achievement Evaluation Program, (AEP) and Academic Aptitude Test (AAT) in elementary and high school graduates, respectively. Results showed that apart from caries (87.5%), most prevalent clinical signs of malnutrition were dermatosis (13.4%), follicular hyperkeratosis type I (13.2%), nasolabial dyssebacea (7.9%), lustreless hair (7.7%), angular stomatitis (4.4%) and cheilosis (2.7%). The number of clinical signs of malnutrition was found inversely and significantly associated with SES, H/A, vitamin A and calcium intake, as well as with EA, besides registering a lower nutrient intake, specially for energy, riboflavin and niacin.(ABSTRACT TRUNCATED AT 250 WORDS)

Cancer often causes malnutrition and specific vitamin and protein deficiencies. Chemotherapy also causes deficiencies by promoting anorexia, stomatitis, and alimentary tract disturbances. Antimetabolite drugs in particular inhibit synthesis of essential vitamins, purines, and pyrimidines. Because vitamin levels in the blood are often nondiagnostic, nutritional deficiency is identified almost exclusively on the basis of clinical signs and symptoms and the patient's response to therapy. Signs and symptoms of cachexia and hypoalbuminemia are common in patients with advanced cancer. Deficiencies of vitamins B1, B2, and K and of niacin, folic acid, and thymine also may result from chemotherapy. Nutritional deficiencies are chemically correctable; however, the tumor must be eradicated to relieve cachexia.

Few studies have determined risk factors for diarrheal deaths in developing areas. The Ministry of Health of Lesotho, southern Africa, reported that 9.5% of children under five years of age who were hospitalized for diarrhea in 1984 died. Of 104 children under five years of age who died during hospitalization for diarrhea, 85% were aged 24 months or younger and had nonbloody diarrhea during the warm season. We conducted two retrospective case-control studies of children aged 24 months or younger admitted for diarrhea at two hospitals in 1983 and 1984, comparing 44 who died with 89 who survived. Eight factors were significantly associated (p less than 0.05) with death at one or both hospitals by univariate analysis: diagnosis of a major infection, age under six months, illness for seven days or more before admission, thrush or stomatitis on admission, severe dehydration, history of vomiting, dehydration that had not improved after 12 hours in the hospital, and fever or subnormal temperature. Multivariate analysis of data from one hospital showed the first three factors to be significantly associated with death. Cases and controls were similar in sex and in degree of malnutrition. This study identified children at high risk for death from diarrhea.

Denture stomatitis has been reported in 11-67% of complete denture wearers. It is more common on the palatal mucosa and in female patients. In Newton's type I denture stomatitis, where the inflammation remains focal, trauma seems to be responsible. In Newton's types II and III denture stomatitis, where the denture-bearing mucosa is diffusely involved, most workers assert that the aetiology is multi-factorial. Evidence is presented incriminating Candida albicans colonization of the fitting surface of the prosthesis in many cases of denture stomatitis promoted by continuous denture wearing. Allergic and primary irritant reactions to the denture base material, systemic predisposing factors including dietary deficiency and haematological disorders, also play a part. In most cases of denture stomatitis, elimination of denture faults, control of denture plaque and discontinuous denture wearing are sufficient treatment. The routine use of antiseptic or antimycotic drugs seems unnecessary.

In 6 villages in the Kathmandu valley of Nepal, an intensive health and nutrition study was conducted on 26 lactating women and their 2-6-month-old infants. Analysis of 24-hour duplicate diet composites indicated that the mothers were consuming approximately 2100 kcal energy/d. The diets contained approximately 62 g protein (11.6% of the calories), 392 g carbohydrate (73.3% of the calories), and 20.9% g fat (8.6% of the calories) and a mean of 24 g neutral detergent fiber. Although anthropometric measurements indicated that the mothers had mild protein malnutrition and inadequate energy reserves, their infants exhibited low-normal weight and length for age. All the mothers had hepatitis A antibodies; 92% had tropical eosinophilia, indicating intestinal parasites; 16% had cheilosis and angular stomatitis, indicating a possible B-vitamin deficiency; and 8% had elevated urinary nitrite, indicating urinary tract infection. There were no unusual physical findings on the infants. Although the children appeared healthy, the mohters showed evidence of multiple infections and possible nutrient deficiencies.

The complete nucleotide sequences of the vesicular stomatitis virus (VSV) mRNA's encoding the N and NS proteins have been determined from the sequences of cDNA clones. The mRNA encoding the N protein is 1,326 nucleotides long, excluding polyadenylic acid. It contains an open reading frame for translation which extends from the 5'-proximal AUG codon to encode a protein of 422 amino acids. The N and mRNA is known to contain a major ribosome binding site at the 5'-proximal AUG codon and two other minor ribosome binding sites. These secondary sites have been located unambiguously at the second and third AUG codons in the N mRNA sequence. Translational initiation at these sites, if it in fact occurs, would result in synthesis of two small proteins in a second reading frame. The VSV and mrna encoding the NS protein is 815 nucleotides long, excluding polyadenylic acid, and encodes a protein of 222 amino acids. The predicted molecular weight of the NS protein (25,110) is approximately one-half of that predicted from the mobility of NS protein on sodium dodecyl sulfate-polyacrylamide gels. Deficiency of sodium dodecyl sulfate binding to a large negatively charged domain in the NS protein could explain this anomalous electrophoretic mobility.

Tumor- and/or therapy-related malnutrition can be a crucial factor in the success of treatment of neoplastic diseases. The aetiology of anorexia in many patients is still unknown. Impaired survival rates and the outcome of therapy are related to the nutritional status, although this has not been investigated in well controlled clinical studies. However, it is generally accepted that it is possible to improve therapy by balancing the diet. It is not known whether additional parenteral nutrition improves survival rates. Therefore, the individually adjusted diet which considers the patient's tastes and disease-related abnormalities (i.e. stomatitis or therapy-related mucosal dryness) should be preferred. Balanced formulas allow an additional caloric intake. In advanced disease status, a difficulty in swallowing or tumors which obstruct the oesophagus or the cardia may make tube feeding necessary. Total parenteral nutrition is possible via venous catheters for weeks or even months if antiseptic principles are followed very carefully. If a dietary concept is included early in cancer therapy, the quality of life is improved and surgical, radio- and/or chemotherapy, when performed, is made easier and more successful.

The hypothesis that social indices and educational level of mother are potential sources of childhood malnutrition was tested in Kampumbu, Zambia. Hemoglobin, hematocrit, protein and albumin levels in children were studied in relation to malnutrition. Six hundred and fifty rural children (306 males and 344 females) aged one and fourteen years exposed to various types of diet and environmental factors were selected randomly. Data on economic status, diet environment and educational attainment as well as other demographic information were collected. The major epidemiological findings were that the difference in the distribution of malnourished children by socio-economic status (as measured by income) and hypochromotrichia, oedema or stomatitis was significant (X2 = 4.1, P less than 0.025), and the relative odds were significantly greater than unity at 0.05 level. Similarly, there was a very significant difference (X2 = 7.4, P less than 0.005) in the distribution of malnourished children by socio-economic status (as measured by house grades) and hypochromotrichia, oedema or stomatitis. The estimated relative odds were significantly greater than unity at 0.05 level. Other variables, including age, history of hookworm, were not found to be determinants of risk for malnutrition.
