Research Priority

How does a hemodynamically significant PDA, defined by composite measures indicating moderate to high volume shunting, influence rates of AKI in the NICU?

Investigate the relationship between PDA shunt volume and short/long term kidney outcomes.

Can kidney dysfunction determine PDA management decisions?

Determine if new kidney biomarkers can detect nuances in PDA pathology and higher risk populations

Does increased shunt exposure increase rates of AKI? CKD?

Correlate rates of AKI and CKD with duration of shunt exposure.

Are different PDA treatment methods more protective against CKD development?

Determine if treating PDAs medically, procedurally, or both influence both short- and long-term kidney outcomes.

Can biomarkers differentiate kidney dysfunction in neonates with hemodynamically significant PDAs?

Determine patterns in NIRS trends and other biomarkers in neonates with a PDA.

Can biomarkers be used to predict treatment success or failure in neonates with hemodynamically significant PDAs?

Evaluate how NIRS and biomarkers change with PDA treatment.

Can NIRS be used to stratify infants with hemodynamically significant PDAs at risk of short and long term kidney damage?

Determine whether a patterned change takes place in NIRS values in neonates with a PDA that varies with AKI stage.
