| Study Title | Deep Metabolic Phenotyping of Newborn Cord Blood Reveals Maternal-Fetal Interactions and Disease Risk |
| Study Type | Untargeted MS and Targeted MS |
| Study Summary | Metabolites are small molecules circulating in the mother, placental, and fetal blood that can have a profound effect on a developing fetus (1, 2). Many metabolites from pregnant mothers cross the placenta to provide energy, structural components, essential nutrients, and signals to the developing fetus (3, 4). Issues with proper transmission of metabolites to the fetus, whether through gestational diabetes, placental insufficiency, or other sources can permanently damage the fetus (5-7). However, quantification of many metabolites entering and exiting the fetus are unknown; associations between microbial metabolites in umbilical cords and disease have not been thoroughly investigated; and there remains a lack of quantifiable metabolic effects of some of the most common medications administered during pregnancy and parturition. Here we identified and quantified many metabolites with a gradient between arterial and venous cord blood; we demonstrated that exogenous metabolites in umbilical cords associate with many health outcomes; and we show that medications can profoundly alter the metabolic milieu of the fetus. We greatly expanded the number of metabolites that demonstrate a gradient between arterial and venous blood, indicating absorption by the fetus, including several essential fatty acids. The microbial metabolites 3-indolepropionic acid, hydroxyhippuric acid and others are associated with many newborn diseases. Lastly, we show that exogenous medications like bupivacaine and betamethasone can have a profound impact on newborn metabolic profile. This study is the most comprehensive study of umbilical cord metabolic and disease associations to date. It reveals important aspects of fetal biology, like the reliance on specific essential fatty acid and taurine. It suggests several interventions in pregnant mothers that may help newborn health, including new fatty acids. This study serves as a valuable reference for investigators wishing to better understand the impact of medications on the developing fetus and neonate. |

| Collection ID: | CO003043 |
| Collection Summary: | Plasma was collected from umbilical cords at the Lucile Packard Children’s Hospital Stanford with permission from the Institutional Review Board (IRB #46411). All umbilical cords were collected and sent for clinically-indicated testing to Pathology where blood gas analysis was performed following Stanford protocol. Leftover and discarded samples were obtained for research. Arterial and venous blood were extracted from umbilical cords by heparinized syringe and transferred to low binding tubes. |
| Sample Type: | Blood (plasma) |
