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...

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 to the extensive developmental and functional changes taking place in the CNS at that time. In this episode, we meet Dr N...

Neonatal encephalopathy (NE) is associated with substantial morbidity and mortality and affects around 1.5/1000 live term births. Predicting the severity and outcome of neonates with NE is therefore vital in order to provide the best care for neonates with NE, and a biochemical marker obtained at birth would therefore be useful to bolster the current scoring system. In this episode, Geoff Marsh speaks to Early Career Investigator Dr. Imran Nazir Mir, from the University of Texas, Southwestern Me...

For term-born infants, low birth weight has been shown to correlate with a broad array of adverse cardiometabolic outcomes, and excess glucocorticoid exposure has been linked to these relationships. Also, intra-uterine growth restriction (IUGR) in term-born infants has been linked to subsequent increases in adrenal androgen activity. In this episode, we meet Kristi Watterberg, a professor of Pediatrics at the University of New Mexico who evaluated the relationship between preterm birth to saliva...

Over-the-counter (OTC) medications are used in an estimated 70% of pregnancies. Acetaminophen, also known as paracetamol is found in a large number of OTC and prescription drugs. Given its prevalence and its ability to freely cross the placenta, researchers are now focusing on the safety of maternal exposure to this drug and its effects on fetal health. There have been inconsistent results in both human and animal studies on the short and long-term effects of acetaminophen use during pregnancy. ...

Almost 10% of newborn infants develop significant hyperbilirubinemia, and many require phototherapy treatment. This is costly and can increase the likelihood of patients developing allergic diseases. However the costs of not treating neonatal jaundice can be more severe as it can cause lifelong disability. Precise patient monitoring and deliberate treatment assignment are therefore essential for at-risk neonates. In this episode, we meet Sven Wellman, then of the University of Basel's Children H...

Placental dysfunction is a leading cause of morbidity and mortality in children. Yet, despite its central importance, there is a lack of tools to assess in vivo placental health. Ex vivo evaluation of placentas has shown there to be micro-architectural changes with fetal growth restriction (FGR), but currently there are no tools to assess this before birth. In this episode, we speak with this month's Early Career Investigator- Prof. Nickie Andescavage from George Washington University, who recen...

In 2015, Brazil experienced an unprecedented epidemic of zika virus infection. Concurrently, there was an increased incidence of children born with primary congenital microcephaly. Researchers quickly suspected a link between the zika virus infection in pregnant women and congenital microcephaly due to the so-called congenital Zika syndrome (CZS). With the impending threat of a second outbreak, Marcio Leyser from the University of Iowa proposes a multilevel-based research framework for CZS, base...

Metabolic syndrome has been a growing problem in recent decades in both adult and pediatric populations. Time-restricted feeding (TRF), has been shown to attenuate metabolic disorders and obesity in adults. It is thought to be superior to surgical interventions and other dietary patterns as it is non-invasive, and does not lead to unbearable hunger. However, there is a lack of data on its effects in pediatric populations. n this episode, we meet Dr. Dandan Hu, who during her time at Peking Union...

Obesity has been shown to be linked with a host of physiological and psychological problems, such as cancer, diabetes and depression. In adults, obesity has also been shown to be related to decreased cognitive function and structural brain differences. The evidence for this effect on cognition is less well established in children and adolescents. In this episode we meet Dr. Stijn Vantieghem from the ARCS research group at the Vrije Universiteit Brussel who conducted a 30 week weight-loss program...

Non-alcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease in the United States. It's all been steadily rising, along with rising obesity levels. Currently, early interventions for NAFLD include dietary, lifestyle counselling, and vitamin supplementation. Recent evidence suggests that the gut microbiota may be involved in the pathophysiology of non-alcoholic fatty liver disease.In this episode, we hear from ECI Maggie Stanislawski from the University of Colorado ...

TB was responsible for 1.8 million deaths in 2015, of which children account for almost 10%. A large proportion of TB patients go undetected in high burden countries due to the poor sensitivity of the smear microscopy used to detect the disease. Paediatric cases are often harder to detect because children produce lower quality sputum samples needed for the smear microscopy. As a result, many children with TB go untreated, and the vast majority of children treated for TB are treated empirically. ...

A major source of second hand smoke (SHS) exposure in infants is the home. Some parents are aware of this risk and make efforts to minimise the exposure by employing a total ban on smoking in the home. However many families opt for a partial smoking ban, only smoking in certain rooms, at certain times, or at certain distances from the child and practice avoidance behaviours like opening windows.In order to better understand how parents' smoking behaviours affected SHS exposure in children, Dr Yi...

Patients with sickle cell disease often experience severe pain as a result of vaso-occlusive episodes. Typically their pain is managed with opioids, however some patients experience continued and increasing pain, believed to be as a result of opioid-induced hyperalgesia or tolerance. Many patients go on to develop chronic pain which is thought to have a neuropathic component, for which opioids are ineffective.Ketamine has been suggested as an adjuvant to opioids to treat chronic and acute pain.I...

One system which is thought to falter in preterm neonates is the cerebrovascular autoregulatory system, which helps to maintain a constant supply of oxygen to the brain. When this system falters in the setting of hypotension, it can lead to intraventricular haemorrhage, which in turn, can lead to serious neuro-developmental impairment. In this episode, we meet Zachary Vesoulis, a Pediatrician at Washington University in St. Louis, who recently published a Pediatric Research paper testing the eff...
