Cynthia L Blanco, M.D.
Professor of Pediatrics with Tenure
Greehey Family Foundation Chair in Neonatology Research
Dr. Blanco is a Professor of Pediatrics with Tenure. Dr. Blanco completed her undergraduate studies and received her MD at the Universidad de Guadalajara in Guadalajara, Jalisco Mexico. She completed her residency in Pediatrics at Texas Tech University and her Post-Doctoral degree in Neonatal-Perinatal Medicine at the University of Texas Health Science Center San Antonio with a Masters in Clinical Investigation. Dr. Blanco serves as a member of the Committee on Nutrition for the American Academy of Pediatrics. She is heavily involved in clinical and translational research. Her research interests are in parenteral and enteral nutrition of the critically ill neonate. Her research focuses on the fetal and neonatal environmental exposures and the effect on glucose metabolism and insulin signaling pathways. Specifically, the ontogeny of gluconeogenesic pathways, pancreatic development and insulin resistance and the alterations when exposed to antenatal steroids and prematurity. She also investigates the effect of intravenous Amino Acid supplementation in ELBW infants and relationship to infants’ metabolism. Her clinical research focus includes enteral nutrition strategies to decrease the incidence of necrotizing enterocolitis with exclusive human nutrition and the biochemical markers involved in pasteurized human milk in relationship with gastrointestinal disease. Due to her passion a Neonatal Nutrition and Bone Institute was established under her leadership at University Hospital San Antonio. In this Institute, body composition analyses can be performed utilizing DXA, body air displacement plethysmography and ultrasound bone scans. In this Institute, we have implemented the utilization of novel therapies such as Intravenous Fish oil and novel markers of liver disease for infants with Parenteral Nutrition Associated Liver disease and short bowel syndrome as a resource to bridge neonates to liver transplant and/or survive them without transplant. Dr. Blanco believes we will continue to improve the health of neonates, children and adults by improving nutrition and metabolism at an early age

Funding Agency San Antonio Medical Fondation Title San Antonio Medical Foundation Status Active Period 8/2016 - 7/2017 Role Principal Investigator Grant Detail The objective of this study is to determine the effects of maternal obesity and diabetes on infantile body composition, growth and epigenetic changes related to free fatty acid/glucose metabolism and diabetes. Body composition is measured serially utilizing the air displacement plethysmography and dual-enegry X-ray absorptiometry. Cord blood is collected for analyses of promoter methylation status of key genes in the insulin signaling, glucose metabolism and free fatty acid pathways.
Funding Agency Bexar County Hospital District Title University Health System Status Active Period 12/2015 - 12/2017 Role Principal Investigator Grant Detail The primary goal of this project is to investigate the effect of hyperglycemia on pancreatic development and peripheral insulin signaling at critical periods of development. The central hypothesis is that prematurity has decreased pancreatic function and further impairments of insulin signaling in skeletal muscle when compared with prematurity not exposed to adverse postnatal environment (hyperglycemia). Pancreatic function is assessed by hyperglycemic clamps and compared to histological endocrine cell development utilizing the CAST system. Insulin signaling molecules and glucose transporters are measured at basal and insulin-stimulated state in skeletal muscle.
Funding Agency Title Clinical Investigator Kickstart Program.Short and long term effects of maternal obesity and diabetes on infantile body composition and epigenetics. Status Active Period 8/2017 - 7/2018 Role Principal Investigator Grant Detail The primary goal of this project is to determine if differentially methylated regions in cord blood of infants of mothers with gestational diabetes and obesity are associated with increased adiposity in offspring. Body composition is measured serially (birth, 3 months and 1 year) by utilizing the air displacement plethysmography and dual-energy x-ray absorptiometry. Methylation status of key genes in the insulin signaling, glucose metabolism, and free fatty acid pathways are measured at 1 year of age. Funding Agency
Title Subaward Agreement Utrecht Medisch Centrum (UMC) Status Active Period 6/2014 - 7/2022 Role Co-Investigator Grant Detail Human Mesenchymal Stem Cell Treatment.
The goal of our experiment is to investigate whether human Mesenchymal Stem Cells when given intranasally are capable of migrating to a cerebral lesion. The main purpose is to offer additional treatment options to newborns born with a global brain injury.
