Spina Bifida Defying Folic Acid Supplementation
نویسنده
چکیده
Pre-conceptional supplementation of folic acid is well known to reduce the incidence of spina bifida. But Athena is frequently perplexed to see this anomaly occurring despite folate supplementation. In a largest Canadian study, De Wal et al [1] screened 1.9 million live births to study the effect of mass fortification. On comparing pre and post fortification periods they noted only 46% reduction in the incidence of neural tube defects (NTD). What happens to the remaining 54%? Why do they defy “folic acid” logics? Recently several publications have shed more light on this intriguing question.

Spina bifida and birth outcome before and after fortification of flour with iron and folic acid in Oman.
This paper presents the trend of spina bifida and other neural tube defects in Oman after the nationwide implementation of folate supplementation of pregnant women in 1990 and the fortification of wheat flour with iron and folate in 1996. The annual incidence of spina bifida fluctuated from 2.34 to 4.03 per 1000 deliveries between 1991 and 1996, but fell sharply to 2.11 per 1000 deliveries in 1...
متن کاملFolic acid supplementation influences the distribution of neural tube defect subtypes: A registry-based study.
Periconceptional folic acid (FA) reduces neural tube defect (NTD) risk, but seems to have a varying effect per NTD subtype. We aimed to study the effect of FA supplementation on NTD subtype distribution using data from EUROCAT Northern Netherlands. We included all birth types with non-syndromal NTDs born in 1997-2012. By Fisher's exact test we analyzed possible differences in NTD subtype distri...
متن کاملNeural tube defects: review of experimental evidence on stem cell therapy and newer treatment options.
The failure of closure of the neural tube during development leads to malformations called neural tube defects (NTDs). The most common neural malformations in humans include anencephaly, encephalocele, exencephaly, craniorachischisis spina bifida with or without myelomeningocele, lipomyeloschisis, lipomyelomeningocele, meningocele and myelocystocele. Current preventive strategies are mainly bas...
