OBJECTIVE More than 70% of the community-acquired (CA) staphylococcal infections treated at Texas Children's Hospital are caused by methicillin-resistant Staphylococcus aureus (MRSA). Since September 2002, an increase in the number of severely ill patients with S aureus infections has occurred. This study provides a clinical description of severely ill(More)
To determine the contributions of galactose and fructose to glucose formation, 6 subjects (26 +/- 2 years old; body mass index, 22.4 +/- 0.2 kg/m(2)) (mean +/- SE) were studied during fasting conditions. Three subjects received a primed constant intravenous infusion of [6,6-(2)H(2)]glucose for 3 hours followed by oral bolus ingestion of galactose labeled to(More)
OBJECTIVES H1N1 influenza with coinfections has been implicated to have high morbidity and mortality. We hypothesized that critically ill children with 2009 H1N1 and coinfections are at a higher risk of developing disseminated intravascular coagulation. DESIGN The chart review included demographics, length-of-stay, severity of illness score (Pediatric(More)
OBJECTIVE To assess the effect of nutritional status and cardiovascular risk on hospital outcomes after congenital heart surgery in infants and children. DESIGN Retrospective study. SETTING Cardiac intensive care unit in a tertiary-care children's hospital. PATIENTS One hundred twenty-one patients <24 months of age admitted to the cardiovascular(More)
BACKGROUND Critically ill children are at high risk of underfeeding and AKI, which may lead to further nutritional deficiencies. This study aimed to determine the adequacy of nutrition support during the first 5 days of intensive care unit (ICU) stay. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS A chart review of pediatric patients admitted to the(More)
The use of prediction equations has been recommended for calculating energy expenditure. We evaluated two equations that predict energy expenditure, each of which were corrected for two different stress factors, and compared the values obtained with those calculated by indirect calorimetry. The subjects were 55 critically ill children on mechanical(More)
We hypothesized continuous veno-venous hemodialysis (CVVHD) amino acid, trace metals and folate clearance impacts nutrient balance. Critically ill children receiving CVVHD were studied prospectively for 5 days. Blood concentrations (amino acids, copper, zinc, manganese, chromium, selenium and folate) were measured at CVVHD initiation, and Days 2 and 5.(More)
BACKGROUND & AIMS To investigate the effects of glucose, parenteral amino acids, and intravenous insulin on albumin synthesis rates in critically ill children. METHODS Two studies were performed in 8 post-surgical infants (age 9.8 ± 1.9 months; weight 9.5 ± 1.1 kg) and 9 septic adolescents (age 15 ± 1 yr; BMI 23 ± 4 kg m(-2)), respectively. All received a(More)
CMAJ • NOVEMBER 23, 2010 • 182(17) © 2010 Canadian Medical Association or its licensors 1831 We have intuitively known for a long time that poor nutritional status in disease is associated with mor bidity and mortality. Only recently, however, have studies provided evidence of an association between poor nutritional status and prolonged hospital stay,(More)
BACKGROUND The evaluation of nutritional status, including body composition measurements, in pediatric patients before and after lung transplant (LTx) can aid in adapting nutrition support and physical rehabilitation programs to meet individual patient needs. The purpose of this retrospective study was to determine the changes in weight, lean body mass(More)
