BackgroundMaternal exposure to polycyclic aromatic hydrocarbons (PAHs) has been associated with the risk of fetal neural tube defects (NTDs). Whether maternal genetic variants related to PAH metabolism contribute to the development of fetal NTDs remains unclear.. MethodsWe conducted a case-control study in a Chinese population to examine the association of selected maternal genetic variants of phase II enzymes involved in the elimination of the metabolic intermediates of these chemicals with fetal NTD risk, and to evaluate possible interaction of the genetic variant and maternal exposure to indoor air pollution from coal combustion and smoking (IAPCC). Blood samples were collected from 534 NTD case mothers and 534 control mothers and assayed for 12 polymorphisms of 5 genes encoding phase II enzymes.. ResultsWe found that the rs9282861 GG genotype of SULT1A1 was associated with an elevated risk of total NTDs (odds ratio [OR] = 2.12, 95% confidence interval [CI]: 1.49-3.00), compared with the GA ...
Neural tube defects are abnormalities that can occur in the brain (anencephaly, encephalocele), spine (spina bifida, myelomeningocele, myelodysplasia), both brain and spine (craniorachischisis) or spinal column of a developing embryo that are present at birth. They arise when the neural tube, the embryonic precursor of the brain and spinal cord, fails to close during neurulation. Many cases of neural tube defects occur worldwide each year in more than 300,000 newborn babies and are a significant cause of infant death and lifelong disability. Most neural tube defects are preventable. The prevalence of these abnormalities has decreased in the past 20 to 30 years due to periconceptional folate supplementation, food fortification and decreased exposure to environmental factors. Women who are planning to conceive should be informed about the importance of folic acid in fetal development and encouraged to take 400 μg/day of folic acid supplements. Numerous research studies have shown that taking this ...
Amniotic fluid samples received for routine prenatal diagnosis of open neural tube defects were used for a study to compare amniotic fluid acetylcholinesterase (AChE) determination using a monoclonal antibody (4F19) enzyme antigen immunoassay and amniotic fluid alpha-fetoprotein (AFP) measurement as diagnostic tests for open neural tube defects. The study was based on 9964 women with singleton pregnancies and known outcome (including 6 with anencephaly and 18 with open spina bifida) having an amniocentesis at 14-23 weeks of gestation. The AChE immunoassay yielded detection rates for anencephaly of 100 per cent (95 per cent confidence interval (CI) 54.07-100 per cent), for open spina bifida of 100 per cent (95 per cent CI 81.47-100 per cent), for anterior abdominal wall defects of 20 per cent (95 per cent CI 0.51-71.64 per cent), and a false-positive rate of 0.22 per cent (95 per cent CI 0.14-0.34 per cent) excluding anencephaly, open spina bifida, and anterior abdominal wall defects. For similar ...
Neural tube defects are defects which affect the neural tube and is the most common type of CNS malformation. As the picture alongside demonstrates, the neural tube develops as the baby grows within the womb. The inside portion of the neural tube forms the ventricular system, and the outside portion forms the brain and the spinal cord. In normal circumstances, the neural tube closes and seals itself before birth, but it may either fail to close or may reopen after closing because it is not sealed properly.. What are the types of tissues affected by neural tube defects? There are several types of tissues which can be affected by neural tube defects: they include neural tissue, bone, soft tissues and the meninges. The most common neural tube defects involve the spinal cord and the type of side effects are dependent on the level at which the defect presents itself. In general, the higher up the spinal cord, the worse the prognosis.. Because the neural tube develops during pregnancy, is there ...
Periconceptional folic acid use can often prevent neural tube defects (NTDs). Variants of genes involved in folate metabolism in mothers and children have been associated with occurrence of NTDs. We identified Irish families with individuals affected by neural tube defects. In these families, we observed that neural tube defects and birth defects overall occurred at a higher rate in the maternal lineage compared with the paternal lineage. The goal of this study was to look for evidence for genetic effects that could explain the discrepancy in the occurrence of these birth defects in the maternal vs. paternal lineage. We genotyped blood samples from 322 individuals from NTD-affected Irish families, identified through their membership in spina bifida associations. We looked for differences in distribution in maternal vs. paternal lineages of five genetic polymorphisms: the DHFR 19 bp deletion, MTHFD1 1958G,A, MTHFR 1298A,C, MTHFR 677C,T, and SLC19A1 80A,G. In addition to looking at genotypes ...

A dye-injection technique has been used to determine the developmental stage at which posterior neuropore (PNP) closure occurs in normal and mutant curly tail mouse embryos. In vivo, the majority of non-mutant embryos undergo PNP closure between 30 and 34 somites whereas approximately 50% of all mutant embryos show delayed closure, and around 20% maintain an open PNP even at advanced stages of development. A similar result has been found for embryos developing in vitro from the headfold stage. Later in development, 50-60% of mutant embryos in vivo develop tail flexion defects, and 15-20% lumbosacral myeloschisis. This supports the view that delayed PNP closure is the main developmental lesion leading to the appearance of caudal neural tube defects in curly tail mice. The neural tube is closed in the region of tail flexion defects, but it is locally overexpanded and abnormal in position. The significance of these observations is discussed in relation to possible mechanisms of development of ...

In response to mounting evidence from observational studies and randomised trials of the benefits of periconceptional folic acid in reducing the risk of neural tube defects, the National Health and Medical Research Council (NHMRC) recommended that women planning a pregnancy or likely to become pregnant should be offered advice about dietary folate and periconceptional folic acid supplementation. Subsequently an NHMRC Expert Panel on Folate Fortification recommended voluntary folate fortification of foods.
Studies suggest that fetal growth and development are influenced by the nutritional status of the mother in the period before she conceives and at the time of conception.
Neural tube defects (NTDs) are a group of birth defects in which an opening in the spinal cord or brain remains from early in human development. In the 3rd week of pregnancy called gastrulation, specialized cells on the dorsal side of the embryo begin to change shape and form the neural tube. When the neural tube does not close completely, an NTD develops. Specific types include: spina bifida which affects the spine, anencephaly which results in little to no brain, encephalocele which affects the skull, and iniencephaly which results in severe neck problems. NTDs are one of the most common birth defects, affecting over 300,000 births each year worldwide. For example, spina bifida affects approximately 1,500 births annually in the USA, or about 3.5 in every 10,000 (0.035% of US births), which has decreased from around 5 per 10,000 (0.05% of US births) since folate fortification of grain products was started. The number of deaths in the US each year due to neural tube defects also declined from ...
Folate hydrolase 1 (FOLH1) gene encodes intestinal folate hydrolase, which regulates intestinal absorption of dietary folate. Previous studies on the association between polymorphisms rs202676 and rs61886492 and the risk of neural tube defects (NTDs) were inconclusive. A case-control study of women with NTD-affected pregnancies (n = 160) and controls (n = 320) was conducted in the Chinese population of Lvliang, a high-risk area for NTDs. We genotyped the polymorphic sites rs202676 and rs61886492 and assessed maternal plasma folate and total homocysteine (tHcy). Our results showed that in case group, plasma folate concentrations were 18 % lower compared with those of control group (8.32 vs. 6.79 nmol/L, p = 0.033) and tHcy concentrations were 17 % higher (10.47 vs. 12.65 μmol/L, p = 0.047). Almost all samples had the rs61886492 GG genotype (99.78 %). The result showed that the frequency of GG genotype in rs202676 was significantly higher in group with multiple NTDs than in controls (p = 0.030, OR = 2
In 2009, Australia implemented mandatory folic acid fortification in wheat flour for bread-making. The primary aim was to improve folate status in reproductive-aged women to reduce neural tube defect incidence. However, folic acid consumption has consequently increased in all demographics. Blood folate is inversely associated with homocysteine levels, a risk factor for multiple diseases. Therefore ...

Neural tube defects affect about 4000 pregnancies each year and are thus among the most common of severe birth defects. Prenatal diagnosis can now detect about 70% of neural tube defects but the tests produce many false positives, so the question is under what circumstances should they be recommended.

Environmental exposure may play an important role in the incidences of neural tube defects (NTD) of birth defects. Their influence on NTD may likely be non-linear; few studies have considered spatial autocorrelation of residuals in the estimation of NTD risk. We aimed to develop a spatial model based on generalized additive model (GAM) plus cokriging to examine and model the expected incidences of NTD and make the inference of the incidence risk. We developed a spatial model to predict the expected incidences of NTD at village level in Heshun County, Shanxi Province, China, a region with high NTD cases. GAM was used to establish linear and non-linear relationships between local covariates and the expected NTD incidences. We examined the following village-level covariates in the model: projected coordinates, soil types, lithodological classes, distance to watershed, rivers, faults and major roads, annual average fertilizer uses, fruit and vegetable production, gross domestic product, and the number of

Neural tube defects are birth defects of the brain, spine, or spinal cord. They happen in the first month of pregnancy. Learn how to prevent them.
Neural tube defects (NTD), including anencephaly and spina bifida, are a group of severe congenital abnormalities in which the future brain and/or spinal cord fail to close. In mice, NTD may result from genetic mutations or knockouts, or from exposure to teratogenic agents, several of which are known risk factors in humans. Among the many mouse NTD models that have been identified to date, a number have been tested for possible primary prevention of NTD by exogenous agents, such as folic acid. In genetic NTD models such as Cart1, splotch, Cited2, and crooked tail, and NTD induced by teratogens including valproic acid and fumonisins, the incidence of defects is reduced by maternal folic acid supplementation. These folate-responsive models provide an opportunity to investigate the possible mechanisms underlying prevention of NTD by folic acid in humans. In another group of mouse models, that includes curly tail, axial defects, and the Ephrin-A5 knockout, NTD are not preventable by folic acid, ...

Neural tube defects (NTDs) are complex abnormalities associated with gene-environment interactions. The underlying cause has not been determined. Spinal cord tissues from cases with NTDs and healthy controls were collected. Methylation patterns between cases and normal individuals were compared using 450K Infinium Methylation BeadChip Illumina. DNA methylation analysis by pyrosequencing (PyroMark Q96) and mRNA and protein expression were analyzed using real-time quantitative PCR and Western blotting, respectively. Next-generation and Sanger sequencing were used to determine genetic variants in the target genes. Spinal cord tissues from cases with NTDs had more hypomethylated than hypermethylated genes. Further evaluation showed that the exon 1 region of TRIM4 was hypomethylated, and TRIM4 mRNA and protein levels were significantly increased in NTDs compared to controls. A rare missense variant (rs76665876) in TRIM4 was found in 3 of the 14 NTD cases but was not related to TRIM4 expression. TRIM4 mRNA

Neural tube defects (NTDs) are malformations of the cranium, spine, and nervous system; types of NTDs include anencephaly, spina bifida, encephalocele, and meningocele. Neural tube defects are a major cause of mortality in newborns and have been estimated to affect 0.5 to 8 per 1000 live births. Health Canada has estimated that 195 Canadian infants are born each year with NTDs. Overall, NTDs affect approximately 300 000 infants worldwide.. Epidemiological studies that associate folate supplementation with a decreased risk of NTDs date back to the 1960s. The most definitive research addressing the benefits of folic acid supplementation in decreasing the risk of NTDs was the multicentre, randomized, double-blind trial by the Medical Research Council in the United Kingdom. 1 The aim of this trial was to evaluate the efficacy of 4-mg doses of folic acid in preventing recurrent NTDs in women who had previously delivered children with NTDs. The trial showed that women randomized to take folic acid ...
This review article combines four disparate observations about Neural Tube Defects (NTDs). They are the worldwide decline in the birth incidence that began prior to prenatal diagnosis; family recurrence risks; the effect of prenatal diagnosis and termination of affected pregnancies; and the effect of folic acid.
Spina bifida occurs while the baby is still developing and growing inside the mother. The babys spine doesnt develop correctly. At birth the spinal cord is open at the back or exposed (also called a neural tube defect). Early in pregnancy, cells form a closed tube (neural tube) that eventually becomes the babys brain and spinal cord. A neural tube defect happens when the tube does not completely close. A neural tube defect can happen anywhere on the spine, but usually happens to the lower part of the spinal cord. A child born with a neural tube defect usually will have difficulty walking, and may need leg braces, crutches, a walker and, in some cases, a wheelchair (Gargiulo, 2001 ...
Mutations in a gene known as interferon regulatory factor 6 that cause cleft lip and palate also are implicated in neural tube defects such as spina bifida, suggests research by an international study team published online Jan. 25, 2019, in Human Molecular Genetics.
IIUniversity of Utah School of Medicine, Department of Family and Preventive Medicine, Salt Lake City, Utah, United States of America. We would like to give a heartfelt thanks to Dr. Tarqui-Mamani for her diligent efforts to decrease neural tube defects (NTD) in Peru.. We recognize that differences between studies may occur, and that it is possible that the differences found between Dr. Tarqui-Mamanis NTD data (as stated in her letter) and our study, "Perus national folic acid fortification program and its effect on neural tube defects in Lima," (1) could be due to a difference in methods. Moreover, we recognize there are limitations to epidemiology studies employing the International Classification of Diseases, 10th edition (ICD-10) (2). Limitations of under-reporting are due to a lack of space on data forms; omissions by coders; and diagnoses made in hospital, but not included on discharge records; whereas limitations of over-reporting occur when the diagnosis made by the clinician or ...
Neural tube defects are congenital development anomaly of the central nervous system and usually have relatively more predilection to affect at anterior and posterior neuropore embryological development sites, so usually one or two defects are commonly encountered. However, occurrence of simultaneous multiple neural tube defects is very rare, presence of constellation of five neural defects is extremely rare, and all defects add up together to produce gross neurological deficit. We present an interesting case of a 23-year-old male who presented with history of lower backache and noticed wasting and weakness of lower limbs associated with difficulty in walking for the last 2 years but had no associated sphincter disturbances ...

DNA methylation is an epigenetic mechanism that regulates the gene transcription. Folate is used in cellular synthesis of methyl groups, nucleic acids and amino acids. In complex diseases like cancer and neural tube defects (NTD), various genetic and epigenetic alterations can be found that disrupt the normal cell function. The main goals of this thesis were to analyze whether the genes responsible for the folate transport (FOLR1, PCFT, and RFC1) could be regulated by DNA methylation in placenta, blood leukocytes and colorectal cancer. We also addressed the genome-wide DNA methylation changes in colorectal cancer andcervical cancer.We found that changes in the methylated fraction of the RFC1 gene were dependent on the RFC1 80G,A polymorphism in placental specimens with NTDs and blood leukocytes from subjects with high homocysteine (Paper I). In colorectal cancer, the greatest difference in DNA methylation was observed in the RFC1 gene and was related to a lower protein expression (Paper II).In ...

Dolutegravir is a widely used anti-HIV drug in the integrase inhibitor class. It is marketed as Tivicay and is a component in the combination pills Triumeq and Juluca. This week, regulatory agencies warned that women with HIV who can become pregnant should not use dolutegravir without effective contraception. This follows a report from Botswana of a higher frequency of birth defects in babies born to mothers who became pregnant while taking dolutegravir. The Botswana study looked at the incidence of neural tube defects in infants born to mothers taking anti-HIV drugs at the time they became pregnant. A neural tube defect occurs when the spinal cord, brain, and related structures do not form properly. Spina bifida - a malformed spinal cord - is the most common neural tube defect.. The study found that four of 426 (0.9%) babies whose mothers became pregnant while taking dolutegravir had a neural tube defect, compared to 0.1% in babies whose mothers were taking other anti-HIV drugs.. Neural tube ...
Study findings suggested that mothers who had first trimester exposures to drinking water contaminated with TCE at Camp Lejeune were more likely to have a child with a neural tube defect compared with unexposed mothers. The higher the mothers exposure to TCE, the higher the likelihood that the child would have a neural tube defect. This finding is consistent with a previous study conducted in New Jersey (Bove FJ, et al. Public drinking water contamination and birth outcomes. Am J Epidemiol 1995, 141:850-862).. Study findings also suggested that mothers who had first trimester exposures to drinking water contaminated with benzene were more likely to have a child with a neural tube defect compared with unexposed mothers. However, we could not look at whether higher benzene exposures increased the likelihood of having a child with a neural tube defect because of small numbers of exposed cases.. Mothers with first trimester exposures to PCE, vinyl chloride, or DCE were more likely to have a child ...

In promoting folic acid awareness, volunteer youth leaders are also promoting the nutritional needs of women in the reproductive age and this has an impact to the well-being of their future child - a target under Goal 2: Hunger and Food Security. It is known that folic acid supplementation is the only proven neural tube defect (NTD) prevention method, to date. Neural tube defects are problems in the development of the brain and the spinal cord. Data from the FNRI-DOST have also shown that 1 out of 5 women in the Philippines is folate deficient (2008 National Nutrition Survey). This shows that public awareness on the importance of folate and folic acid is also low among Filipinos ...
Im sorry that it has been awhile since my last post, but my research has demanded more attention lately. Ive seen something interesting in my project, so Ive been working on understanding what exactly happened. I am trying to answer the question of how.. This question of how is important, but it often goes unanswered in science and biomedicine.. The prevention of neural tube defects is an example of the question of how going unanswered. Neural tube defects, or NTDs, are caused when the developmental processes of neural tube closure go awry. The neural tube becomes the brain and spinal cord, so a fully functional nervous system depends on the tube forming properly. Neural tube closure is a complex process, and is very prone to error. The prevalence of neural tube defects in the United States is estimated as 1 in every 1000 live births. This is not a trivial number.. NTDs include anencephaly, which is when the head region fails to close. This defect is invariable lethal, since the brain fails ...
For the most recent study, the researchers fed mice the combination of quats and, in many cases, also exposed them to airborne levels and surface residues of disinfectant mixtures resulting from routine cleaning of the labs and cages. The result was a 150 percent increase in the rate of neural tube defects, a type of fetal abnormality that can occur in rodents and people. Neural tube defects are the second most prevalent form of birth defects in humans, and most frequently manifest as spina bifida, a condition often associated with nerve damage; muscle weakness; and walking, learning, bladder and bowel problems ...
The US Public Health Service recommends that all women of childbearing age consume 400 micrograms (0.4 mg) of folic acid each day. Folic acid, a nutrient found in some green, leafy vegetables, most berries, nuts, beans, citrus fruits, fortified breakfast cereals, and some vitamin supplements can help reduce the risk of birth defects of the brain and spinal cord (called neural tube defects). The most common neural tube defect is spina bifida (in which the vertebrae do not fuse together properly, causing the spinal cord to be exposed) which can lead to varying degrees of paralysis, incontinence, and sometimes mental retardation.. Folic acid is most beneficial during the first 28 days after conception, when most neural tube defects occur. Unfortunately, many women do not realize they are pregnant before 28 days. Therefore, folic acid intake should begin prior to conception and continue through pregnancy. Your physician/midwife will recommend the appropriate amount of folic acid to meet your ...

Nutrition during pregnancy is important to ensure healthy growth of the fetus.[75] Nutrition during pregnancy is different from the non-pregnant state.[75] There are increased energy requirements and specific micronutrient requirements.[75] Women benefit from education to encourage a balanced energy and protein intake during pregnancy.[76] Some women may need professional medical advice if their diet is affected by medical conditions, food allergies, or specific religious/ ethical beliefs.[77]. Adequate periconceptional (time before and right after conception) folic acid (also called folate or Vitamin B9) intake has been shown to decrease the risk of fetal neural tube defects, such as spina bifida.[78] The neural tube develops during the first 28 days of pregnancy, a urine pregnancy test is not usually positive until 14 days post-conception, explaining the necessity to guarantee adequate folate intake before conception.[63][79] Folate is abundant in green leafy vegetables, legumes, and ...
Prenatal folic acid supplements appear to reduce the risk for autistic spectrum disorders, according to a study published today (February 13) in the Journal of the American Medical Association (JAMA).. The Centers for Disease Control and Prevention estimate that about 1 in 88 children in the U.S. have been identified with an Autism Spectrum Disorder (ASD). ASDs are amongst the most heritable of mental disorders, but little is known about how the disorder develops. Consequently, methods for diagnosis, prevention, and treatment are limited.. Folic acid (Vitamin B9) is required for DNA synthesis and repair in the human body, and its naturally occurring form-folate-is found in leafy vegetables, peas, lentils, beans, eggs, yeast, and liver. Taking folic acid supplements during early pregnancy is known to protect against spina bifida and other neural tube defects in children. In the United States, Canada, and Chile, folic acid is added to flour, so as to automatically provide these supplements to ...

Women with high-quality diets during the year before pregnancy were at lower risk than were those with poor diets for delivering a baby with orofacial clefts or neural tube defects, according to a study. This finding, from an analysis of data in the ongoing National Birth Defects Prevention Study (NBDPS), is "notable" because previous analyses of the same data, "which assessed single-nutrient intakes in isolation, had not been informative. "In particular, maternal intake of folic acid-containing vitamin/mineral supplements was not associated in the NBDPS with a reduced risk of neural tube defects, and findings for dietary folate were inconsistent" in these previous analyses, said Suzan L. Carmichael, Ph.D., of Stanford (Calif.) University and her associates. "[Our] findings suggest that overall diet quality is more predictive of birth defect risk than intake of single nutrients," they noted. Dr. Carmichael and her colleagues developed two indexes of dietary quality, one modeled after the ...
Researchers have found that a woman who gets enough folic acid (vitamin B-9) can help lower the risk for neural tube defects. Folic acid is found in some leafy green vegetables, nuts, beans, citrus fruits, and fortified breakfast cereals. It is recommended that all women of childbearing age take a multivitamin that has folic acid. Folic acid is in prenatal vitamins. Getting this vitamin before a woman knows she is pregnant and early in pregnancy is most important. If you have had a child with a neural tube defect, your healthcare provider may recommend taking a larger amount of folic acid before your next pregnancy. Your provider may tell you to take this extra amount for 1 to 2 months before conception and then through the first trimester. Your healthcare provider may also advise genetic counseling. You can discuss with a counselor the risk for a neural tube defect in a future pregnancy. Also talk with your provider about getting a prescription for folic acid to lower the risk for another open ...
