Neonatal serum protein levels as indicators of nutritional status: normal values and correlation with anthropometric data.

Twenty-one infants were studied to compare cord serum protein concentrations (SPCs) with samples drawn 3 days after birth. The results were compared with anthropometric measurements of the infants to determine the usefulness of serum studies in predicting the nutritional status of the newborn. SPCs of 19 serum protein subfractions were measured by laser nephelometry. In 17 of 19 proteins, the cord blood and newborn blood levels were highly correlated. C1Q and haptoglobin were the exceptions. The SPC was converted to serum protein mass (SPM) as follows: SPM = [(SPC) x (birth weight) x (0.85) x (1-hematocrit)]. Blood volume is approximately 0.85 dl of blood/kg of body weight and since these proteins are largely intravascular, it was postulated that the estimated total protein mass would be a more accurate index of nutritional state. Six proteins (C3, C4, prealbumin, retinol binding protein, transferrin, and albumin) were highly correlated with the anthropometry (arm circumference, skin fold thickness, length, weight, etc.). This study indicates that umbilical cord blood may be used to estimate a newborn's nutritional status. Transport proteins such as albumin, transferrin, retinol binding protein, and prealbumin are commonly used to assess adult nutritional status, and may be used in infants after estimating the total mass of the protein in the serum.

Nutritional care of the surgical neonate.

The function of the nutritionist was to identify and anticipate nutritional problems, to facilitate complete care for each infant, and to serve as an educational resource to staff, patients, and families. Neonatal nutrition is an open and challenging field for nutritionists. An expanded role for the nutritionist as a member of the physician-nutritionist team, as demonstrated in this article, may provide direction for the organization of such a team in other health care facilities with neonatal intensive care units.

Impact of fast food meals on nutrient intake of two groups.

Two groups in different population centers were studied to determine how often consumers frequented fast food restaurants, and consequently, how heavily they relied on this type of food for nutrients. A questionnaire was answered by 280 customers of two fast food restaurants of the same chain. They were asked how often they patronized fast food restaurants, their specific food choices, and other pertinent questions. Food choices were evaluated for energy and seven nutrients on the basis of published analyses of the menu items of the particular fast food chain. Fifty-two per cent of the subjects in the two groups considered their purchases to be meals. Seventy-seven per cent of these consumed one-third or more of the recommended dietary allowance for protein, but no more than 30 per cent received that amount of the other nutrients examined, including food energy. Calcium and particularly vitamin A were least often consumed in amounts equal to one-third of the recommended allowances. Consumer choices were responsible for low consumption of calcium, but no good sources of vitamin A were included on the menus. Fast food items were purchased so infrequently by the majority of our respondents that nutrient composition of the fast food meals or snacks would be of concern in only a small number of cases. This study indicates that any attempts to improve nutritive value of fast food snacks or meals must include efforts to lead consumers to make wiser food choices, as well as encourage the fast food industry to provide rich sources of all the nutrients in their menus.

Survey of nutritional problems encountered in children with neuromotor disorders.

A survey of 200 patients ranging in age from 5-21 yr was undertaken in 3 facilities in central Pennsylvania: state- (100), county- (13), and privately-operated (66), together with 21 children being cared for at home. Their diagnoses included chromosomal, metabolic, and anatomic abnormalities, and other encephalopathies. The following nutritional problems were identified: 1) inadequate nutrient intake due to feeding technique, swallowing difficulties, or regurgitation; 2) obesity and low activity level; 3) constipation; 4) nutrient-drug interactions and allergies; and 5) inadequate standards with which to compare growth and adequacy of nutrient intake. The nutritional problems encountered in these pediatric patients with neuromotor disorders warrant management by a physician-nutritionist team skilled in nutritional assessment and techniques of providing nutritional support.
