Noninvasive Screening Of A Fecal Biomarker For Human Necrotizing Enterocolitis (Nec), Daniela Campa, Kyle Sullivan

Bioengineering Senior Theses

Necrotizing enterocolitis (NEC) is a disease that predominantly affects preterm infants. Of the 10% of preterm neonates that develop NEC, about one in four cases results in death. The pathophysiology presents as inflammation of intestinal epithelial cell lining and subsequent tissue death, sometimes resulting in intestinal perforations. The underlying mechanisms have yet to be comprehensively identified. Diagnosis--the rate limiting step in reducing critical disease-onset-to-treatment time--is based on relatively nonspecific signs, impeding early and accurate diagnosis. This project, a collaborative effort between Santa Clara and Stanford Universities, aims to improve current diagnostic methods by identifying the first verifiable and useful fecal …
