Question: Human milk has stronger antiviral, antibacterial, and anti-inflammatory properties compared with formula milk. How dose breastfeeding affect respiratory syncytial virus infection in Korea?
Finding: Breastfed infants required less oxygen therapy and possible intensive care unit admission than artificial formulafed infants during respiratory syncytial virus infection.
Meaning: This protective role of breast milk on RSV severity can be a supporting evidence for promoting breastfeeding in Korea.

Variation in clinical usefulness of biomarkers of acute kidney injury in young children undergoing cardiac surgery
Hee Sun Baek, Youngok Lee, Hea Min Jang, Joonyong Cho, Myung Chul Hyun, Yeo Hyang Kim, Su-Kyeong Hwang, Min Hyun Cho
Clin Exp Pediatr. 2020;63(4):151-156.   Published online February 5, 2020
Question: Can clinical usefulness of biomarkers of acute kidney injury vary on the clinical circumstances?
Finding: In young children undergoing cardiac surgery, urine KIM-1/Cr level peaked at 24 hours with significant difference from baseline level and was significantly higher at 6 hours in the AKI group. However, urine NGAL/Cr and IL-18/Cr levels showed no specific trend with time for 48 hours after cardiac surgery.
Meaning: Urine KIM-1/Cr concentration could be considered a good biomarker for early AKI prediction after open cardiac surgery in young children.
