||Glycosylation changes in glycoproteins in urine [ Time Frame: After delivery of preterm infant, less than one year ] [ Designated as safety issue: No ]
In participating women who deliver preterm, the collected urine specimens will be analyzed to evaluate glycosylation changes in glycoproteins, specifically uromodulin.

|Brief Title ICMJE||Glycoproteomic Analysis of Urine in Women Undergoing Spontaneous Preterm Delivery|
|Official Title ICMJE||Glycoproteomic Analysis of Urine in Women Undergoing Spontaneous Preterm Delivery|
When babies are premature, or born before they are fully developed, they face many different medical problems, some of which are quite devastating, such as cerebral palsy, mental retardation, blindness, deafness, severe intestinal problems, and developmental delays. Unfortunately, in more than half the cases of premature births, there is no procedure or test that an obstetrician can employ to predict if a fetus is at risk for premature birth, especially when the mother is healthy. This study seeks to determine if certain factors found in the urine undergo specific changes that can be used to detect premature births of this type before they happen.
In this study, the investigators will identify women with a history of preterm delivery between 24-32 weeks, 32-34, and 34-36 weeks gestation based on diagnosis codes in the medical record who are currently pregnant. The investigators will ask these women when they are in the 16-20 week into their pregnancy to fill out a questionaire to determine study eligibility. If chosen to participate, the investigators will ask them to collect their first morning urine samples before each of their remaining prenatal care appointments for our studies. The investigators will also ask them if the investigators can check their medical records to determine if they later had a premature baby. If these women in either group give birth prematurely, then the investigators will analyze the glycoproteins in their urine samples using known values from women who did not have a premature birth as controls. If the investigators can see any changes in glycosylation in the women who gave birth prematurely, then this information will be used to apply for a larger study that will determine if such changes apply to all women. If it can then be shown to apply to all women, then the investigators may use it to predict preterm delivery. This information would allow physicians to design treatments to help these women and their babies, and spare them these disabilities. Some women go into labor prematurely, well before they should give birth. Physicians can intervene in some cases to stop labor, and allow the fetus to develop further in the mother's womb. However, in more than half the cases the physician cannot stop this process, and the baby is born prematurely.
