| Study Title | Integrated trajectories of the maternal metabolome, proteome, and immunome predict labor onset |
| Study Summary | Estimating the time of delivery is of high clinical importance as pre- and post-term deviations are associated with complications for the mother and her offspring. However, current estimation approaches are inaccurate. As pregnancy progresses towards labor, major transitions occur in fetomaternal immune, metabolic, and endocrine systems that culminate in the delivery of the fetus. The comprehensive characterization of metabolic, proteomic and immune cell events that precede the spontaneous onset of labor is a key step to understanding these physiological transitions and identifying predictive biomarkers of parturition. Here, over 7,000 circulating plasma analytes and peripheral immune cell responses collected during the last 100 days of pregnancy were integrated into a multi-omic model that accurately predicted the time to spontaneous onset of labor (R = 0.85, p-value = 1.2e-40, training set; R = 0.81, p-value = 3.9e-7, independent test set). Coordinated fluctuations marked a molecular shift from pregnancy progression to pre-labor onset biology 2–4 weeks before delivery. Our study lays the groundwork for developing blood-based methods for predicting the onset of labor, anchored in mechanisms shared in preterm, term, and postterm pregnancies. |
