Pediatric Research Podcast

Researchers in pediatrics have much to be proud of from their last four decades of work. From cutting fatalities from Sudden Infant Death Syndrome, to vaccinations that have protected the lives of millions, Dr. Tina Cheng and colleagues believe that these achievements would not have been possible without a strong research base. Hear more from Tina in this podcast.

A baby's healthy growth depends on receiving the right balance of energy and nutrients. If a baby is born pre-term, its carers must provide the nutrition it would otherwise have received in the womb. Surprisingly, there is very little consistency in studies of neonatal nutrition and growth regarding how much energy and nutrients should be administered to preterm infants, and the expected growth trajectories. A team from the University of Auckland in New Zealand have looked at 22 studies and developed a way to standardize this information.

It's usually the job of the researcher to devise a hypothesis, set up a trial, and collect data. But in participatory research, some of this power is handed to the study participants; in the case of paediatric research, it's given to children. The idea is to have children play an active role in the questions being asked, the data collection process, and any actions that result from a study. A new paper sets out to find examples of participatory research in paediatrics and gives suggestions on best practices.

The brains of preterm babies are delicate - and mysterious. It can be difficult to assess what is happening in the brains of babies born preterm, in order to work out the best course of action. The SafeboosC II trial tested whether using a brain imaging technique called NIRS (Near Infrared Spectroscopy) on preterm infants could guide diagnosis, and whether it could help reduce the burden of hypoxia. It had the desired clinical effect - but two biomarkers of brain injury were not reduced in line with the burden. Researchers Gorm Greisen and Anne Mette Plomgard discuss this unexpected result.

It's not just biology that determines the health of an infant or child - and the adult they will become. Social and environmental factors such as parenting, the home environment, substance use in the home or child abuse can have important impacts on pediatric health and later life repercussions. The January 2016 issue of Pediatric Research features several reviews on the social determinants of health. Guest editor Margie Skeer talks through a few examples.

A lack of oxygen or blood to the brain in newborn babies can lead to brain damage. One promising treatment currently being trialled in animal models involves giving a type of stem cell by inhalation. Before the therapy can be tested in humans, though, scientists need to know it is safe and won't cause uncontrolled cell growth in the brain. A new report in Pediatric Research now establishes its safety.

Caffeine makes the adult world go round - but could it also be used as a therapy for premature babies? Several studies have suggested that in premature babies with breathing difficulties, caffeine could help stimulate them to breathe on their own and even have a positive effect on their brain development. But by contrast, a new study in Pediatric Research finds that a high dose of caffeine can have harmful effects.

Our bodies are home to more bacterial cells than human cells. These bugs are collectively known as our microbiota. But when we're born, we have very few. Max Vento studies how infants amass their community of bugs and what effect being born preterm has. And it's the subject of a review, in which he and his colleagues also outline how the microbiota of preterm babies can be impaired, and how to coax it into health.

At the moment of birth, babies go through the most disruptive physiological transition they will ever experience: they rid their lungs of fluid and start to breathe. Then the umbilical cord is clamped, shutting off air and blood supply from the mother and cementing their independence. New insights into this process, detailed in a review article by Stuart Hooper and colleagues, could help ease the transition for babies who have problems beginning to breathe on their own.
