Filter by:The goal of this research study is to discover the genetic and environmental factors that contribute to the cause of neural tube defects such as spina bifida and anencephaly. Ultimately, this type of research may result in improved diagnosis, improved treatment and possibly prevention.
The purpose of this study is to determine whether the study drug is safe and effective
The aim of the study is to develop a randomised, double blind clinical trial to compare (i) folic acid plus inositol, with (ii) folic acid plus placebo, for prevention of recurrent neural tube defects.
Investigate the efficacy of weekly versus daily of folic acid supplementation on improving folate, vitamin B12,
In a collaborative effort with the Health Research Board, the national organization for medical research in the Republic of Ireland, individuals with neural tube defects (NTDs) or facial cleft defects and their parents will be studied. With the exception of a few well-described syndromes most cases of NTDs and facial clefts are not inherited in a Mendelian fashion. Nearly all incident cases occur in families with no prior history of the defects. The observed recurrence risk in families with an NTD child is 10-12 fold higher than the general population suggesting that inherited factors modify this risk. Historically, the incidence of NTDs in Ireland was 5-8 fold higher than the USA. The aim of this study is to identify the gene(s) involved in these defects using standard genetic epidemiology approaches, transmission disequilibrium testing and gene mapping strategies. We will initially evaluate genes known to be involved in folate metabolism and pattern formation (development of the body). The major outcomes measured will be aggregate allele frequencies in case groups compared to controls. Biochemical parameters in red cells and plasma will also be measured. Comparisons will be made between the presence of genetics variants, biochemical parameters and clinical phenotype. Characterizing the genes associated with these defects should provide insight into the etiology and metabolic processes that may be involved, furthering prevention and intervention efforts.
The purpose of this study is to compare red blood cell folate levels in women who are taking oral contraceptives with or without folic acid
The aim of this study is to examine whether the same total daily dosage of folic acid, when taken as a single daily dose or as multiple divided doses throughout the day, results in different blood folate and homocysteine levels at the conclusion of the study. Further, a comparison of blood folate and homocysteine levels among women taking daily low-dosage (100mcg) and standard- dosage (400mcg) folic acid with those of women taking daily or weekly high-dosage (4000mcg) folic acid will be conducted.
Spina bifida (myelomeningocele) is a complex birth defect in which a portion of the spinal cord is not fully developed. The overlying bones and skin are incompletely formed and the underdeveloped area of the spinal cord is exposed on the surface of the back. Spina bifida defects are closed soon after birth to prevent further damage to the spinal cord and nerves. The Management of Myelomeningocele Study (MOMS) is a research study comparing two approaches to the treatment of babies with spina bifida: surgery before birth (prenatal surgery) and the standard closure, surgery after birth (postnatal surgery).
