Decreased Intraoperative Renal Tissue Oxygenation after Cardiopulmonary Bypass Predicts Cardiac Surgery-Associated Acute Kidney Injury in Neonates.

(1) Background: Near-infrared spectroscopy (NIRS) is a noninvasive tool frequently used during cardiac surgery and postoperatively in the cardiac intensive care unit to monitor regional tissue oxygen saturation. A relationship between trends of intraoperative renal oxygenation and the risk of developing cardiac surgery-associated acute kidney injury (AKI) post-operatively has not yet been established in the neonatal population. The objective of this study is to evaluate the relationship of cerebral and renal oxygenation during cardiopulmonary bypass with cardiac surgery-associated AKI in the first 72 h post-operation in neonates < 30 days of age.

Renal tissue oxygenation and development of AKI in preterm neonates born < 32 weeks' gestational age in the first week of age.

Objective: To evaluate the relationship between regional renal saturation of oxygen (RrSO) changes and serum creatinine (SCr) during the first eight days of age for preterm neonates born < 32 weeks' gestational age.

Design: Post-hoc analysis of multicenter prospectively measured neonatal RrSO values collected during the first 8 days of age in neonates born at < 32 weeks' gestation. Acute kidney injury (AKI) was defined by the neonatal modified Kidney Disease: Improving Global Outcomes (KDIGO) criteria.

Liver Transplantation for Refractory Congenital Cytomegaloviral Hepatitis.

Congenital cytomegalovirus (cCMV) is the most common congenital infection. Here, we report on a case of severe, refractory cCMV hepatitis resulting in end-stage liver disease. A male infant born at 37 weeks gestational age presented with petechiae, splenomegaly, and jaundice associated with a direct hyperbilirubinemia, elevated transaminases, and thrombocytopenia.
