Biography:

Dr. Marin is currently an Assistant Professor at Augusta University, and is an active researcher in the Level IV NICU at Children’s Hospital of Georgia. She received her BSN from the University of Tennessee, her MSN from Stony Brook and her PhD from Emory University. Dr. Marin’s program of research is focused on defining non-invasive methods to predict early-onset acute kidney injury in preterm infants, including analysis of metabolomics, proteomics, the gut-kidney microbiome axis, and renal hypoxia measured by near-infrared spectroscopy as they relate to subclinical and actual acute kidney disease.

Physiologic Biomarkers to Detect Subclinical Acute Kidney Injury in Premature Infants
Acute kidney Injury (AKI) prior to the completion of nephrogenesis at 34 weeks’ gestation has significant life-long effects. The immature kidney only receives 3-4% of total cardiac output, compared to 20% in term infants, children and adults. Therefore, minimal decreases in oxygen delivery may substantially compromise proper oxygen utilization increasing the risk for morphologic changes and reduced nephron endowment. Current diagnostic criteria (serum creatinine (sCr) elevations with oliguria) cannot detect early-onset AKI, as up to 50% of nephron damage has already occurred by the time these abnormalities become apparent. This presentation will look at new research related to the current diagnostic criteria for AKI in the preterm infant, the physiologic mechanisms involved in AKI and short and long-term implications.
