Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The investigators plan to enroll 50 neonates in our study. The investigators will catalog all exposure to plasticizers during the infant's NICU admission and assign each baby a risk level of exposure. The investigators will then test each infant's performance on a neurological screening tool, measure growth from birth and assess whether or not each infant has thyroid dysfunction and correlate each outcome with exposure risk level. The investigators will also collect urine samples from each baby to store for possible future analysis.
The investigators hypothesize that neonates with higher levels of exposure will demonstrate worse performance on the neurological screening tool, poor growth, and abnormal thyroid function.
