However, there are other genetic and environmental causes that prenatal vitamins alone cannot correct. , Environmental risk factors have been identified that contribute to neural tube defects, including the lack of folic acid supplementation and low dietary intake of folate described above. In utero therapies that increase fetal function and survivalīirth defects are the leading cause of infant deaths, affecting approximately one in every 33 live births (about 3%) in the United States each year and accounting for 20% of all infant deaths. The primary determinant associated with a live embryo or fetus was ultrasound detection of a heartbeat. found that in the normal population, women with a viable pregnancy at less than 12 weeks’ gestation as detected by ultrasound showed 98% fetal survival up to 28 weeks. published similar findings that, if a live fetus is documented by ultrasonography at 8-12 weeks’ gestation, survival to at least 20 weeks’ gestation is 98.0%. Doubilet et al., showed that ultrasound detection of a normal heartbeat at 7 weeks‘ gestation predicted 91.5% survival to the end of the first trimester, and those survivors proceeded at a rate of 95.1% to be liveborn infants. showed that presence of a heartbeat at 6-8 weeks’ gestation correlated with a live birth rate of 98% in normal pregnancies without intervention. Bae and Karnitis found that detection of fetal cardiac activity at 7 weeks’ gestation had a 90.5% predictive value for fetal survival and ongoing pregnancy. found that ultrasound detection of fetal cardiac activity at 6 weeks’ gestation had a 93% positive predictive value for successful completion of the first trimester in IVF pregnancies. Even early detection of fetal heartbeat points to long-term survival. Numerous published studies document that detection of a fetal heartbeat, verification of a live embryo or fetus, is a prognostic indicator for survival of the fetus to term. Įarly heartbeat detection is a prognostic indicator of fetal survival Despite the fact that the influenza vaccine is safe and reduces risk for mom and baby, about ½ of pregnant women still do not get vaccinated. A 2018 study found that vaccination reduced a pregnant woman’s risk of being hospitalized with the flu by an average of 40 percent. Vaccination for influenza (the flu) is recommended for all pregnant women to reduce the risk of severe illness caused by the influenza virus, which could be fatal. Maternal immunization can also provide indirect protection, achieved through prevention of maternal infection and through breast milk antibodies. Maternal immunization boosts the concentration of maternal antibodies, which can transfer across the placenta to the baby, providing protection until the infant is old enough to be immunized after birth. Vaccines administered during pregnancy can provide protection for the mother and baby against serious infectious diseases. A key study from 2015 found that the proportion of babies in the population born with a neural tube defect has decreased by 35% in the United States resulting in about 1,300 more babies born healthy without a neural tube defect each year because of mandatory fortification. Since starting mandatory folic acid fortification of cereal grain products in the United States in 1998, more babies have been born healthy. For this reason, the CDC urges all women of reproductive age who might become pregnant to consume 400 mcg of folic acid every day, in addition to consuming food with folate from a well-balanced diet. Babies with the most severe form called myelomeningocele may have severe neurologic and intellectual impairment, including paralysis.įolic acid has been proven to reduce the incidence of neural tube defects in women with one or more previously affected children and in women who have no risk factors. Spina bifida is another serious birth defect in which a baby’s spine does not develop correctly. Anencephaly is a serious birth defect in which parts of a baby’s brain and skull do not form correctly. The two most common types of neural tube defects are anencephaly and spina bifida. Perhaps the best-known and most extensively studied prenatal intervention is maternal consumption of folic acid (Vitamin B9) in her diet prior to conception and during pregnancy for reducing the risk of serious birth defects of the baby’s brain (also known as neural tube defects). A mother’s daily consumption of folic acid and immunization are important proactive steps that every mother can take to decrease the risk of disease for herself and her baby. With advancements in science, non-surgical interventions are available to women that can increase pregnancy health.
