The Codex Alimentarius Commission of the Food and Agriculture Organization of the United Nations (FAO) and the World Health Organization (WHO) develops food standards, guidelines and related texts for protecting consumer health and ensuring fair trade practices globally. The major part of the world's population lives in more than 160 countries that are(More)
Whole body oxidation of dietary stearic, oleic, and linoleic acid was measured in males consuming a test diet of normal foods at a level commensurate with energy requirements for 16 days. Labeled stearic, oleic or linoleic acid was consumed with the breakfast meal on either day 8, 11, or 14. Breath samples were analyzed for total CO2 content and 13CO2(More)
BACKGROUND & AIMS Congenital tufting enteropathy (CTE) is a rare autosomal recessive diarrheal disorder presenting in the neonatal period. CTE is characterized by intestinal epithelial cell dysplasia leading to severe malabsorption and significant morbidity and mortality. The pathogenesis and genetics of this disorder are not well understood. The objective(More)
This report is a summary of a meeting convened by the Cystic Fibrosis Foundation to develop a consensus among nutrition specialists and cystic fibrosis care givers regarding optimal nutritional management of patients with cystic fibrosis. The first section of the report provides a rationale for emphasizing nutritional management of this genetic disorder.(More)
Advancement in treatment has resulted in a dramatic increase in life expectancy of patients with cystic fibrosis (CF) to well beyond 30 years of age in most centres. What was once a fatal genetic disease in childhood now sees over a third of its CF populations in adult clinics. The improved survival is multifactorial, but most attribute the reasons to more(More)
PURPOSE Treatment for acute lymphoblastic leukemia (ALL) in childhood results in a reduction in bone mineral density (BMD). Whether there is a recovery of this lost bone mass in survivors of ALL is not known. We sought to determine if changes in BMD are common long-term sequelae in children with ALL. METHODS Bone mineral densitometry of the lumbar spine(More)
We tested the hypothesis that aging affects whole-body protein turnover via altered fat-free mass (FFM). Whole-body protein kinetics were estimated by the 60-h oral [15N]glycine method. Results from 16 healthy, elderly subjects (8 men and 8 women with a mean age of 72.6 y) were compared for age and sex effects with those of 15 lean young subjects (8 men and(More)
Lysine requirement was determined in seven adult males by examining the effect of varying dietary lysine intake on phenylalanine flux and oxidation under dietary conditions of adequate energy and phenylalanine (14 mg.kg-1 x day-1) and excess tyrosine (40 mg.kg-1 x day-1). Phenylalanine flux was determined from primed, constant intravenous infusions of(More)
PURPOSE To evaluate a technique of retrograde insertion of gastrostomy and gastrojejunostomy tubes with radiologic guidance in children. MATERIALS AND METHODS During a 4 1/2-year period, 511 patients underwent attempted insertion of gastrostomy or gastrojejunostomy tubes. Patients' ages ranged from premature to 18.6 years (mean age, 3.8 years), and weight(More)
Phenylalanine metabolism was determined in 41 studies of adult males (n = 10) consuming an energy-sufficient diet and receiving graded levels of dietary phenylalanine and excess tyrosine (40 mg.kg-1.day-1). After a dietary adaptation period to either 4.2 or 14.0 mg.kg-1.day-1 of phenylalanine; flux, plasma concentration, oxidation, and conversion to(More)
