Filter by:Iron deficiency anemia (IDA) is a widespread condition affecting many people globally. Despite the many cases of IDA, there are few studies that compare the effectiveness of different types of iron supplements with a greater emphasis on the cost of supplements and their tolerability. This study aims to conduct a comparison between different iron supplements to determine the superiority of the iron supplements Ferrous Ascorbate (EBMfer) and Ferrous Fumarate (Eurofer) over polysaccharide iron (FeraMax). This comparison will be conducted by determining the change in hemoglobin levels for participants in this trial over a 3-month period.
This observational study was designed as a prospective epidemiological screening study. Patients who have applied to the centers participating in the study and who have previously been clinically or pathologically diagnosed with PAP (Pulmonary alveolar proteinosis) will be included in the study. Up-to-date data will be collected from patients who have agreed to participate in the study, and a blood sample with DBS will be taken from patients. The blood taken will be subjected to analysis for ADA metabolites. For patients with a high metabolic test, the responsible researcher will advise on clarifying the diagnosis with a genetic test other than the study. In case of formation of new information for each patient, consultation will be provided by the responsible researcher. Thus, the prevalence of ADA enzyme deficiency disease will be evaluated in patients diagnosed with PAP.
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.
