Recent Research may Improve Outcome for Premature Babies

Scientists at Cardiff University have hit upon a novel way to change the manner of lung development in the embryo, which is a promising development for premature babies

In collaboration with scientists at the Saban Research Institute at Los Angeles Children's Hospital, the researchers discovered that a molecule called CaR (calcium receptor) is a crucial factor in the control of lung development in the womb.

'Lac-test' A Promising Tool To Predicts Onset Of Preterm Labour
Researchers have found that high levels of lactate in vaginal fluid is strongly linked to onset of labour within 48 hours.

CaR co-ordinates messages from within the growing foetus that instruct the lungs to develop thousands of channels and tiny air pockets.

This complicated structure is what will ultimately allow oxygen to move from the air into the baby's blood stream.

The study was carried out in the laboratories of Dr Daniela Riccardi and Professor Paul Kemp (School of Biosciences, Cardiff University, UK) in collaboration with Professor David Warburton (Saban Research Institute, Childrens Hospital Los Angeles, USA).

Feeding Premature Babies by Cup may Not Be of Much Help
Traditionally, hospitals and parents have used bottles or tubes to feed infants when breastfeeding was not possible. In some cases, hospitals have turned to cup feeding

"Within minutes of birth, a baby relies solely on its lungs to get the oxygen it needs. One of the reasons that the lives of very premature babies are in such dire jeopardy is that the final stages of lung development happen very late in pregnancy and so premature babies are born with immature lungs that struggle to take in enough oxygen. Under-developed lungs don't absorb enough oxygen and premature babies with respiratory problems often develop chronic lung disease that may extend into adulthood.

He added: "Through our research we have gained a better understanding of how lungs develop normally and so we can now begin to work out what happens when things go wrong, such as when a baby is born much too early. From the work we have published today, we now have a real possibility for fast-tracking new drugs for helping these very premature babies." said Riccardi.

Study: Preemies are Four Times More Prone to Behavioural Disorders
Premature babies are four times more likely to have emotional problems or behavioural disorders later in life than their peers, according to a new study.

Kemp said: "The really exciting thing about CaR is that there are already drugs available that can alter its function and, therefore, could modulate lung development. We know that CaR works by sensing calcium and we also know that there are already drugs available that are designed to regulate how calcium is used in the body. If we can show that one of these drugs can modulate the action of CaR in the lung, it could be used to mature the lungs of a very premature baby as it grows. Better still, an existing drug could potentially be approved much more quickly than a new one."

Professor Janet Allen, BBSRC Director of Research said: "It is exciting to see that BBSRC-funded research has the potential to improve the lives of thousands of very premature babies.

Premature Babies Do Experience Pain
University College London researchers have revealed that premature babies do experience pain and that is factor is often overlooked.

These scientists have shown that by first asking questions about a fundamental biological process, the possibilities for understanding and treating devastating human disease can then be thrown wide open. This demonstrates the value of basic research in biology for delivering real life impact."

The research is published in the latest issue of The Journal of Physiology.
