    Prevalence and stability of insufficient sleep measured by actigraphy: a prospective community study

    Prevalence and stability of insufficient sleep measured by actigraphy: a prospective community study

    There is a growing body of evidence to suggest that insufficient sleep can have detrimental effects on school-age children's cognitive, emotional and behavioral regulation. But there remains a lack of objectively measured data on the stability and prevalence of insufficient sleep. In this episode, we meet Bror Ranum who is currently doing his PhD at the Norwegian University of Science and Technology. He was involved in a large prospective study of almost 800 children between the ages of 6-12 years to objectively measure the prevalence and stability of insufficient sleep using actigraphy. The results suggest the importance of measuring the number of nights of insufficient sleep as opposed to only taking an average measure over a week.

    A novel, composite measure of screen-based media use in young children (ScreenQ) and associations with parenting practices and cognitive abilities

    A novel, composite measure of screen-based media use in young children (ScreenQ) and associations with parenting practices and cognitive abilities

    Young children face unprecedented access to screens in the modern environment. It was recently estimated that children between the ages of 3-8 get almost 3 hours of screen use a day. The American Academy of Pediatrics (AAP) have recommendations for screen-based media use which focus on four variables: access to screens, frequency of use, content and grownup-child interaction, or “co-viewing". In this episode, we meet Early Career Investigator, Dr John Hutton, from Cincinnati Children's Hospital Medical Centre, who has created a composite measure of these variables, reflecting current modes of screen-based media use.

    Demographic and psychosocial factors associated with hair cortisol concentrations in preschool children

    Demographic and psychosocial factors associated with hair cortisol concentrations in preschool children

    There is a growing body of evidence to suggest that early life stress can have detrimental effects on a child's physical and mental health. Hair cortisol concentrations are increasingly accepted as a cumulative measure of stressful experiences but they are understudied in preschool children. In this episode, we meet Professor Sunny Anand from Stanford University School of Medicine who developed a sensitive assay for hair cortisol concentrations. He and his team took hair samples from children aged 1-4 years in order to uncover psychosocial and demographic factors associated with this measure of physiological stress.

    Sex-specific relationships between early nutrition and neurodevelopment in preterm infants

    Sex-specific relationships between early nutrition and neurodevelopment in preterm infants

    In this episode, we meet Early Career Investigator, Dr Anna Tottman who during her time at the University of Aukland, Liggins Institute performed a retrospective cohort study looking at the relationship between neonatal nutrition and neurodevelopmental outcomes. Her research suggests that nutrition for preterm infants may need to be sex-specific. Take a listen!

    Fetal exposure to mercury and lead from intrauterine blood transfusions

    Fetal exposure to mercury and lead from intrauterine blood transfusions

    Preterm infants regularly need Packed red blood cell transfusions. This life-saving therapy can help prevent anaemia of prematurity and in turn, safeguard normal organ function. However, there is a risk that donor blood contains the heavy metals mercury (Hg), lead (Pb) and Cadmium (Cd) which are known developmental neurotoxicants and may be present in neurotoxic doses. In this episode we meet Alison Falck, Assistant Professor of Pediatrics at the University of Maryland School of Medicine who has studied the relationship between the donor concentration, number of transfusions and exposure in preterm infants. Her results may have implications for prescreening of donor blood.

    Eye-tracking during simulation-based neonatal airway management

    Eye-tracking during simulation-based neonatal airway management

    Medical Simulation is a powerful model for pediatric education. This type of experiential training is used to teach various skills including stressful medical tasks like resuscitation, without putting patients at risk. In order to better understand the behavior of healthcare providers during these situations, researchers have started to use eye-tracking technology. In this episode, we meet Early Career Investigator, Michael Wagner from the Medical University of Vienna, who during a fellowship at the Yale University, carried out a simulation-based study using eye-tracking glasses to explore the gaze behavior and subjective experience of care-givers during a neonatal resuscitation to assess the usability of this technology for training.
