MedicalResearch.com Interview with: Thomas Thymann PhD DVM MSc Department of Veterinary and Animal Sciences Comparative Pediatrics and Nutrition Faculty of Health and Medical Sciences University of Copenhagen Frederiksberg, Denmark MedicalResearch.com: What is the background for this study? What are the main findings? Response: Infants that are born preterm are at risk of developing a severe and life threatening intestinal disease referred to as necrotizing enterocolitis (NEC). This condition is known to be under influence of several factors including the microorganisms that start to colonize the intestine immediately after birth. We wanted to see whether fecal matter collected from healthy 10-day old piglets, would benefit the pattern of early colonization, and prevent NEC. (more…)

MedicalResearch.com Interview with: Melissa Lorenzo MD Pediatric medical resident Dr. Lorenzo is currently training at the University of Toronto, however the research was conducted while a medical student at Queens University MedicalResearch.com: What is the background for this study? Response: Preterm infants are born before 37 weeks gestation, with late preterm neonates defined as infants born between 34 weeks to 37 weeks gestation. Of all preterm births, over 70% of babies are born in the late preterm period. Late preterm births are common, affecting 12.5% of all births in the United States. Compared to infants born at term, late preterm neonates are at increased risk for many common complications following birth such as jaundice, low blood sugar, and respiratory distress, prolong hospital stay, admission to the neonatal intensive care unit, and increase readmission rate after hospital discharge. There are many causes for preterm delivery- two important ones are early onset of labour either spontaneous or after premature rupture of membranes, and medically indicated delivery prior to full term gestation due to chronic diseases in mother affecting her health in pregnancy, fetal medical reasons, or placental insufficiency. There is a debate that the risk of neonatal complications is affected by the causes of preterm delivery with immaturity acting as a contributing factor. The relative contribution of immaturity versus the reason for delivery and the resulting neonatal complications is unclear. (more…)

MedicalResearch.com Interview with: Scott D. Grosse, PhD National Center on Birth Defects and Developmental Disabilities CDC MedicalResearch.com: What is the background for this study? What are the main findings? Response: The U.S. Institute of Medicine (IOM) in 2007 published estimates of the economic costs associated with preterm birth. That report is publicly available: https://www.ncbi.nlm.nih.gov/pubmed/20669423. The total societal cost over a lifetime of a single year’s cohort of infants born preterm was estimated as $26 billion in 2005 US dollars. The study in Pediatrics sought to provide more current estimates of one component of those costs: medical care between birth and 12 months and to answer two additional questions:
- What costs are specifically incurred by employer-sponsored private health plans?
- How much of the overall cost burden of prematurity is attributable to infants born preterm with major birth defects (congenital malformations and chromosome abnormalities)?

MedicalResearch.com Interview with: Dr. Hans Jorgen Stensvold, M.D and Dr. Arild Ronnestad, MD PhD Neonatal Department, Oslo University Hospital and the Norwegian Neonatal Network, Oslo, Norway MedicalResearch.com: What is the background for this study? Response: Over the last decades, advances in perinatal care have led to improved survival of extremely preterm infants in most countries. Still, the decision to initiate or withhold active care for infants at the border of viability is challenging. Different attitudes and traditions in perinatal care influence the rates of stillbirths, admissions to intensive care and outcomes. Consequently, there is a continuous need for up-to-date results to guide caregivers and parents in decision making, and to evaluate current medical practices. (more…)

MedicalResearch.com Interview with: Prof. Dr. Dirk Bassler, MSc Department of Neonatology Zurich Switzerland Medical Research: What is the background for this study? What are the main findings? Response: The lungs of preterm infants are very vulnerable and these infants frequently develop chronic lung disease, also called bronchopulmonary dysplasia (BPD). BPD is not only a problem of the lungs, it is also a major cause of early death in these infants and if they survive, their risks of respiratory problems in later life and neurodevelopmental impairment are increased when compared to infants without bronchopulmonary dysplasia. Few drugs are available to prevent or to treat BPD and up to this date, no licensed drug for this indication is on the market, neither in Europe nor the USA. Hence additional preventive strategies are needed to reduce the risk of BPD and inhaled glucocorticoids seemed to have a favorable benefit-risk ratio. Medical Research: What are the main findings? Response: A total of 863 preterm infants with a gestational age of less than 28 weeks from 40 study centers in 9 countries (8 European countries and Israel) participated in the Neonatal European Study of Inhaled Steroids (NEUROSIS). The study investigated whether inhaled budesonide, an anti-inflammatory glucocorticoid, would decrease the incidence of bronchopulmonary dysplasia and death in preterm infants. The results show for the first time that inhaled budesonide reduces the incidence of BPD in preterm infants, a finding that is statistically significant. However, in absolute numbers, more infants died during the study period in the budesonide group compared to the placebo group. This difference is not statistically significant and could be caused by chance. Budesonide had a statistically significant positive effect on two more prespecified secondary outcomes: it reduced the rate of infants requiring intubation after completion of study treatment and the frequency of surgery required to close a patent ductus arteriosus, a blood vessel connecting the pulmonary artery to the aorta. The rate of side effects was similar in the budesonide and in the placebo group. (more…)

MedicalResearch.com Interview with: Prof. Dr. med. Christian F. Poets Neonatologie, Univ.-Klinikum Tübingen Tübingen Germany Medical Research: What is the background for this study? Prof. Poets: Episodes of intermittent hypoxemia (lack of oxygen) and bradycardia (slow heart rate) are common in very preterm infants and often a subject of considerable concern. However, up to now there has been a lack of knowledge as to how often or how long such episodes may occur without increasing an infant’s risk for impaired development or even death. In this study, we utilized long-term recordings (lasting 8-12 weeks) of oxygen saturation and heart rate obtained as part of the Canadian Oxygen Trial (COT), a large study performed in extremely immature infants and comparing a higher with a lower oxygen saturation target range (85-89 vs. 91-95% oxygen saturation measured by pulse oximetry). For this secondary analysis, we wanted to test the hypotheses that spending a high proportion of time at an oxygen saturation below 80% or a pulse rate <80 beats per minute increases the risk of the following adverse outcomes:
- Death after reaching a post-menstrual age of 36 weeks (i.e. 4 weeks before their due date) or disability, determined at 18-22 months corrected age and defined as motor impairment, cognitive or language delay, severe hearing loss, or bilateral blindness;
- Motor impairment (determined at 18-22 months corrected age);
- Cognitive or language delay (determined at 18-22 months corrected age);
- Severe retinopathy of prematurity.

MedicalResearch.com Interview with: Prof. Michael Breakspear MB BS, Ba(Hons), Bsc(Med), PhD QIMR Berghofer Medical Research Institute Royal Brisbane Hospital Medical Research: What is the background for this study? What are the main findings? Prof. Breakspear: The first 72 hours following complicated full-term or premature delivery of a newborn represents a critical window in which survival and long term brain development hangs in the balance. During this window of time, there does not currently exist a reliable, non-invasive, real-time measure of neuropathology that provides neurologists and neonatologists prognostic indicators of clinical outcome. We developed a tool that draws on techniques in physics used to characterize naturally occurring phenomena, such as earthquakes and avalanches, to analyze brain activity recordings of preterm infants. Our tool allows early identification of preterm infants at significant risk of developing poor long-term neurodevelopmental outcomes, such as cerebral palsy and learning difficulties at two years of age.
