One thing that is extremely tough to predict is the birth of a baby. The doctors usually suggest a date, but the baby is born before or after it. A premature baby needs to be kept in an incubator for some time and is at risk of developing infections too. But can this premature birth be forecasted? Apparently yes! A recent study elaborates on this.The study was published in 'Scientific Reports'.A signature found in the cheek cells of mothers and fathers of preterm infants may help develop a test to determine whether a pregnancy may end too early. Such a test could help prevent premature births and the many resulting health impacts on infants by alerting medical providers to the need for early intervention measures.In the study, researchers documented more than 100 epigenetic biomarkers in mothers of preterm babies that were distinct from mothers of babies carried to term. Fathers had fewer biomarkers but enough to indicate a likely paternal role in preterm birth."The signature we found was present in all the parents we analyzed," said senior author Michael Skinner, a professor in Washington State University's School of Biological Sciences. "This is likely to lead eventually to a very useful test. We used buccal cells, which are collected by a cheek swab. It's very non-invasive and easy to do."Epigenetics are molecular factors and processes around DNA that determine how genes behave. While independent of DNA sequence, epigenetic modifications, which can be caused by things such as toxicant exposure, poor nutrition and alcohol use, can also be inherited.In this study, researchers found that the preterm female babies carried more than 100 of these biomarkers, indicating the propensity to have a preterm baby may be passed down. That transgenerational capacity is also supported by the fact the signature is found in cheek cells, Skinner said. If an epigenetic modification is present in both sperm and ovum, the resulting baby will have that modification present in every cell of their body - including their cheek cells.For this study, the researchers took cheek swabs from two groups of mother-father-infant triads shortly after the babies were born. In one set of 19 triads, the infants were born premature and in another group of 21 triads, the babies were carried to full term. The epigenetic analysis revealed the signature in the mothers, fathers and female preterm babies, but none in the male preterm infants.This was a "proof of concept" study and the researchers noted that the next step would be to test this with greater numbers of parents and children.Early birth before 37 weeks of gestation can be fatal for infants, and many who survive, face a host of health issues, some of which can follow them their entire lives, including cognitive disabilities and cardiovascular problems. There are many risk factors that can cause preterm birth such as a twin or multiple pregnancies and the high-blood-pressure condition known as preeclampsia - but some early births are unexpected. Having a diagnostic test in the first term of pregnancy can allow caregivers to take steps to delay or prevent a preterm birth, Skinner said.Skinner's lab had previously published studies on other potential epigenetic biomarkers, including one for autism and rheumatoid arthritis, paving the way for earlier treatment."Although we may not be able to fix the problem, if we know that it's going to develop because of these diagnostics, we can treat it," said Skinner. "This could help with the transition from reactionary medicine to preventive medicine."( With inputs from ANI )Disclaimer: This post has been auto-published from an agency feed without any modifications to the text and has not been reviewed by an editor
