Filter by:Fludarabine and clofarabine are chemotherapy drugs used extensively in bone marrow transplantation. The goal of this study is to determine what causes some children to have different drug concentrations of clofarabine and fludarabine in their bodies and if drug levels are related to whether or not a child experiences severe side-effects during their bone marrow transplant. The hypothesis is that clinical and individual factors cause changes in clofarabine and fludarabine drug levels in pediatric bone marrow transplant patients and that high levels may cause severe side-effects.
The "North Carolina Clinical Genomic Evaluation by Next-gen Exome Sequencing, 2 (NCGENES 2)" study is part of a larger consortium project investigating the clinical utility, or net benefit of an intervention on patient and family well-being as well as diagnostic efficacy, management planning, and medical outcomes. A clinical trial will be implemented to compare (1) first-line exome sequencing to usual care and (2) participant pre-visit preparation to no pre-visit preparation. The study will use a randomized controlled design, with 2x2 factorial design, coupled with patient-reported outcomes and comprehensive clinical data collection addressing key outcomes, to determine the net impact of diagnostic results and secondary findings.
This is a retrospective study aimed at establishing a database of the current health of adult patients with IEM in the French-speaking part of Switzerland. .
Succinylcholine is a myorelaxant agent often used during rapid sequence induction for patients who need to undergo general anesthesia but who are at risk of pulmonary aspiration of gastric content. Whereas other myorelaxant agents are monitored with train of four stimulation to assess onset and duration, few anesthesiologists use train of four stimulation for onset of succinylcholine, as the anesthesiologists evaluate the effect with the time from injection (usually one minute) and the muscle fasciculation due to the release of acetylcholine. The data available on onset duration of this drug are old and bases on only few studies, but the succinylcholine if sometime harmful (anaphylaxis , cardiac arrest, bronchospasm). The investigators want to assess the onset time of succinylcholine with an objective toll , the train of four stimulation, and evaluate if the clinical judgment of the anesthesiologist is reliable to predict an adequate moment for endotracheal intubation.
This study evaluates the efficacy of rifampin in the treatment of hypercalcemia and/or hypercalciuria in participants with at least one inactivating mutation of the CYP24A1 gene. Eligible subjects will receive rifampin for a total of 16 weeks during this study.
Under the joint efforts of genetic and intensive expert, to establish the high-throughput whole exon sequencing(WES) and analysis all the possible pathogenic genes. To provide patient with the appropriate treatment for genetic disease. Besides, it can identify the genetic factor of idiosyncrasy or susceptibility to explain the medical difficulties and give patients personalized advice.
To evaluate the acceptability, tolerance and effect on metabolic control of PKU Explore, a renovated Phe free protein substitute for the dietary management of PKU in children from 6 months to 5 years.
To evaluate the acceptability, tolerance and effect on metabolic control of PKU Start, a new Phe free protein substitute for the dietary management of PKU in infants from birth.
Background: High fructose intake increases blood lactate, triglyceride and uric acid concentrations. Uric acid may contribute to insulin resistance and dyslipidemia in the general population. In patients with hereditary fructose intolerance fructose consumption is associated with acute hypoglycemia, renal tubular acidosis, and hyperuricemia. Objective: We investigated whether asymptomatic carriers for hereditary fructose intolerance (HFI) would have a higher sensitivity to adverse effects of fructose than the general population. Design: Eight subjects heterozygous for HFI (hHFI; 4 males, 4 females) and eight controls received for 7 days a low fructose diet and on the eighth day ingested a test meal calculated to provide 25% of basal energy requirement containing labeled fructose (13C fructose 0.35 g/kg), protein (0.21 g/kg) and lipid (0.22 g/kg). Total fructose oxidation, total endogenous glucose production (by 6,6-2H2-glucose dilution), carbohydrate and lipid oxidation, lipids, uric acid, lactate, creatinine, urea and amino acids were monitored for 6 hours.
The NC NEXUS research study is exploring the utility of next generation sequencing in newborn screening and parental decision making. The National Institutes of Health (NICHD and NHGRI) are co-funding this study under a single U-19.
