To study the effect of chronic ketosis on exercise performance in endurance-trained humans, five well-trained cyclists were fed a eucaloric balanced diet (EBD) for one week providing 35-50 kcal/kg/d, 1.75 g protein/kg/d and the remainder of kilocalories as two-thirds carbohydrate (CHO) and one-third fat. This was followed by four weeks of a eucaloric(More)
OBJECTIVE To assess the usefulness of mid-upper arm circumference (MUAC) as a substitute for body mass index (BMI: kg/m2) or an additional measure of adult nutritional state. DESIGN Variously sampled adults aged 18-60 years from selected regions of five African countries, India, China and Papua New Guinea were measured. SUBJECTS 2421 men and 3248 women(More)
A thorough awareness of the nutritional and metabolic status of the hospitalized patient is crucial for all persons directly involved in patient care. The catabolic nature of the body's response to illness or injury induces a serious drain on vital organs and tissues. Therefore, a complete assessment of the body's various compartments must be carefully(More)
Three, single-day nutritional surveys at weekly intervals were conducted in the general medical wards of an urban municipal teaching hospital. The techniques of nutritional assessment included anthropometric measures (weight/height, triceps skin fold, arm-muscle circumference, serum albumin, and hematocrit). The prevalence of protein-calorie malnutrition(More)
Stress hyperglycemia is common and likely to be associated with at least some of the same complications as hyperglycemia in true diabetes mellitus, such as poor wound healing and a higher infection rate. The predominant cause is the intense counterregulatory hormone and cytokine responses of critical illness, often compounded by excessive dextrose(More)
This study was performed to characterize and compare the actions of insulin on hepatic glucose production and peripheral glucose utilization during infusions of endotoxin, tumor necrosis factor (TNF), interleukin-1 (IL-1), and a combination of IL-1 and TNF in the rat. The euglycemic hyperinsulinemic clamp technique was combined with a primed-constant tracer(More)
A prospective randomized crossover trial was conducted to determine the effect of a branched chain amino acid (BCAA)-enriched solution on whole body leucine kinetics and fractional rates of albumin synthesis in patients with intra-abdominal metastatic adenocarcinoma. Ten malnourished cancer patients were provided isonitrogenous amounts of both a(More)
The effects of recombinant interleukin-1 (IL-1), given as a continuous infusion for 6 days, on host responses were determined in rats. The development of fever, change in food intake and body weight, and key components of the acute-phase response in energy and protein metabolism were assessed. The effects of IL-1 were compared with those observed in a(More)
