Dr. Luc P Brion has published more than 170 manuscripts and 12 chapters and presented more than 110 abstracts. During his training in pediatrics and in neonatology, he participated and conducted studies on growth, nutrition and assessment of renal function in neonates and children. As Faculty at the Albert Einstein College of Medicine in New York (AECOM), he was funded for years by the NIH, American Heart Association, Genentech Foundation, and Pharmacia for basic sciences research in developmental nephrology, specifically renal acid secretion, carbonic anhydrase, pathophysiological effects of acidosis and growth. Dr. Brion has served on the IRB at AECOM. Dr. Brion was Director of the Fellowship Training Program in Neonatal-Perinatal Medicine at AECOM in 1997-2006. 

Dr. Brion was Director of the Fellowship Training Program in Neonatal-Perinatal Medicine at UTSW in 2007-2019. He has been research mentor for more than 30 trainees. He is a member of the Neonatal Review Group of the Cochrane Collaboration. He has participated in 5 randomized controlled trials (RCTs) in preterm infants and several multi-center research studies. From 2009 until 2023 he was the University of Texas Southwestern (UTSW) Alternate PI for the NICHD Eunice Kennedy Shriver Cooperative Multicenter Neonatal Research Network (NRN). Dr. Brion served on the subcommittee on protection of human subjects of the NRN. 

Dr. Brion's current research interest includes (1) improving nutrition and growth in very preterm and very low birth weight infants to optimize neurodevelopment and to reduce signs suggestive of metabolic syndrome in high-risk preterm infants and (2) using evidence-based medicine to improve morbidity and morbidity in neonates. 

In preterm infants fed human milk, milk fortification can be adjusted by 1) optimization, based on growth rate and serum analyses, or 2) individualization, based on daily human milk nutrient analysis. Randomized allocation to adjusting macronutrients based on breast milk analysis in preterm neonates did not improve weight gain, linear growth or weight/length disproportion at 36 weeks postmentrual age or discharge. Follow-up at 18-38 months showed that the type of feeding supplementation had no effect on Bayley scores. At 3 years of age, infants in the experimental arm (individualized fortification) had central obesity and higher serum leptin:adiponectin ratio and central obesity compared with controls. Notably, serum leptin:adiponectin ratio was strongly correlated with weight gain and anthropometric measurements suggesting central obesity.  

Valid serial length measurements in preterm infants were shown to permit characterization of growth patterns. A quality improvement project using adjustable feedings plus accurate serial length measurements was successful in reducing excessive weight gain and weight length disproportion at discharge without affecting linear growth, head growth or neurodevelopment. Among extremely low gestational age neonates (ELGANs) a serum Zinc concentration was obtained in 52 with insufficient linear growth (17%). Zinc supplementation for >2 weeks improved head growth to discharge or 50 weeks postmenstrual age in infants with Zinc deficiency. Additional studies are in process to assess linear growth, ventricular size and neurodevelopment. 

A quality improvement project is in progress at Parkland Hospital, aiming at reducing necrotizing enterocolitis stage II or greater (Bell classification) among high-risk neonates, i.e., those born with gestational age < 33 weeks and those with birthweight < 1500 grams. Another project is designed to assess risk for either death or developing necrotizing enterocolitis stage III.

In 2013 Dr. Brion took the Clinical Safety and Efficacy Course at UTSW. He supervises a team of research nurses who maintain the Divisional extensive neonatal intensive care unit (NICU) clinical databases at Parkland and Children’s Medical Center and databases for the Vermont Oxford Neonatal Network (VON) and Children’s Hospital Network Database (CHND). He compiled and presented an Annual Report of mortality and morbidity of neonates admitted to Parkland NICU and compared them to those of the NICHD NRN, VON and national data. He has used the databases for quality improvement and for research.

Dr. Brion retired on April 10, 2023 and is now professor emeritus.
