Caffeine administration has been associated with reduced rates of Acute Kidney Injury (AKI) in preterm neonates but the effect of caffeine on renal oxygenation is unknown.  In this episode, we meet this month's highlighted Early Career Investigator, Dr. Matthew Harer from the University of Wisconsin School of Medicine and Public Health. He has been investigating the potential use of...

Early on in the SARS-CoV-2 pandemic, the majority of infected children were either asymptomatic or had mild COVID-19 disease, prompting many to demand a higher acceptable risk threshold for pediatric vaccines. More recently, as children begin to make up a larger proportion of the infected population and following evidence of the mental and physical toll exacted by the pandemic on childre...

Juvenile idiopathic arthritis (JIA) is one of the most common inflammatory joint diseases in children. Previous studies have shown that in the oligoarticular subtype of this disease, T cells play a central role in pathogenesis. T cell inhibitory receptors (IRs) seem to play an important role in the development of tolerance and recognition of self and non-self antigens. Ligands binding to these IRs...

Chorioamnionitis is an intrauterine infection of the placenta and fetal membranes. It is the leading cause of preterm delivery and is a common risk factor for adverse pulmonary outcomes such as bronchopulmonary dysplasia. There is evidence to suggest that the first negative impacts on pulmonary development occur in utero in the presence of chorioamnionitis. In this episode, we meet assistant profe...

Previous studies have shown an association between fluid retention during the early postnatal period and increased BPD. However, these studies were performed nearly two decades ago meaning their results may not apply to the contemporary NICU setting, with its widespread use of surfactants and modern incubators. In this episode we meet this month's featured Early Career Investigator Marc Beltempo f...

Respiratory support plays a crucial role in the care of preterm infants in the NICU, ensuring that they get enough oxygen during this critical period of development. But it is becoming increasingly clear that former preterm infants who have been exposed to ventilatory support are at an increased risk of developing asthma and other respiratory disorders. In this episode, we...

Extremely preterm infants are at a high risk for brain injury, and this risk is most severe in children with intraventricular hemorrhage followed by post-hemorrhagic ventricular dilation. Bedside cranial ultrasound allows clinicians to identify the progressive dilation of the lateral ventricles, however, there is currently no consensus on how to quantitatively estimate this dilation and at wh...

Acute kidney injury (AKI) causes significant morbidity and mortality in children, including prolonged hospital stays, increased risk of in-hospital death and future risk of hypertension and progression to chronic kidney disease. Whilst it is quite common, it often goes unrecognized, especially outside of the critical care setting. In this episode, Geoff Marsh speaks to Dr. Shin...

The latter half of gestation and early neonatal life are critical periods for the maturation of the autonomic nervous system. Premature infants are born with underdeveloped autonomic maturation and must undergo their developmental changes in a vastly different setting to the natural, in utero environment. A number of studies have shown autonomic dysmaturation in premature...

Pediatric chronic kidney disease (pCKD) results in a life-long burden that requires routine care. Neurocognitive dysfunction, specifically impairment on tasks of executive function, is a well-established comorbidity but there is a paucity of data exploring the neurobiology of these cognitive deficits. In this episode, we meet early career investigator, Dr Lyndsay Harshman, a pediatric ne...

Therapeutic Hypothermia has long been the standard of care for infants with moderate to severe neonatal encephalopathy. However, the future of treatment for neonatal encephalopathy (NE) will focus on hypothermia adjuvant therapies. There needs to be a rethink in how future NE clinical trials are designed and analyzed, according to a multi-disciplinary expert panel who met at the 'Hypoxic-Ischemic...

Pediatric Pulmonary hypertension (PAH) is a heterogeneous disease, characterized by sustained elevation of pulmonary arterial pressures and death from right ventricular failure. Given the extremely high burden of morbidity and mortality associated with this disease, and the risk of the invasive procedures required for diagnostics, novel biomarkers for this disease would be beneficial. In...

Effective decision making in the Pediatric Intensive Care Unit relies on quickly ascertaining diagnostic information in order to deliver a tailored clinical response. The utility of rapid genetic testing of critically ill patients has been demonstrated several times, owing to their relatively high diagnostic yield. However the cost and slow turnaround of results have been major barriers in th...

Smoking in adults and adolescents is at an all-time low today, yet around 1 in 2 children who visit the Emergency Department have been exposed to tobacco smoke. We know that there numerous health consequences associated with tobacco smoke exposure (TSE), and that this also comes at a substantial monetary cost- in 2010, child tobacco smoke exposure resulted in more than 101,570 annual ED visits, co...

Institutions and healthcare systems had started to introduce wellness initiatives following the growing realization of the widespread problem of physician distress and burnout. Whilst these programs might be effective, there is currently a lack of evidence about who uses them and whether they are best suited to their target audience. In this episode, we meet Dr. Andrea Weintraub from the Icahn Sch...

40% of infants with hypoxic ischemic encephalopathy (HIE) go on to develop long-term disability, despite receiving therapeutic hypothermia. Mounting evidence suggests that children with HIE are at a higher risk of both hypoglycemia and hyperglycemia, which may explain the variable outcomes to therapeutic hypothermia. In this episode, we meet this month's featured Early Career Investigator Dr. Paol...

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 Technolo...

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-view...

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 Medic...

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! Hosted on Acast. See acast...

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 episo...

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 C...

Clinical studies have shown that newborns can experience up to 14 painful procedures each day of admission at the neonatal intensive care unit. There is evidence that these early experiences can cause changes to the developing nervous system affecting, amongst other things, nociception in adulthood. Preterm infants are at particular risk from repeated noxious procedures owing t...

Cumulative exposure to psychosocial adversity in the early years of life can have an adverse effect on early child development (ECD).  Focus on ECD is growing globally, yet to date, the bulk of research on adverse psychosocial experiences and child development has taken place in high-income, Western countries, despite a large burden in developing countries. This month, we meet Early Career In...

A number of clinical variables are used to predict the likelihood of childhood epilepsy, however, additional predictors are needed to improve patient stratification for those at the highest risk of recurrent seizures. In this episode, we meet Adam Numis from the University of California San Francisco, who set out to assess the utility of circulating cytokines as a predictor of childhood epilepsy....
