Filter by:Early Check provides voluntary screening of newborns for a selected panel of conditions. The study has three main objectives: 1) develop and implement an approach to identify affected infants, 2) address the impact on infants and families who screen positive, and 3) evaluate the Early Check program. The Early Check screening will lead to earlier identification of newborns with rare health conditions in addition to providing important data on the implementation of this model program. Early diagnosis may result in health and development benefits for the newborns. Infants who have newborn screening in North Carolina will be eligible to participate, equating to over 120,000 eligible infants a year. Over 95% of participants are expected to screen negative. Newborns who screen positive and their parents are invited to additional research activities and services. Parents can enroll eligible newborns on the Early Check electronic Research Portal. Screening tests are conducted on residual blood from existing newborn screening dried blood spots. Confirmatory testing is provided free-of-charge for infants who screen positive, and carrier testing is provided to mothers of infants with fragile X. Affected newborns have a physical and developmental evaluation. Their parents have genetic counseling and are invited to participate in surveys and interviews. Ongoing evaluation of the program includes additional parent interviews.
This study aimed to examine metabolic response to a short-term fructose enriched diet in carriers for hereditary fructose intolerance compared to controls. Effects of fructose coffees will be assessed in 7 healthy volunteers and 7 subjects with heterozygous mutation for ALDOB gene in a randomized, controlled, crossover trial.
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.
