MIF and necrotizing enterocolitis: We investigated plasma MIF levels in neonates during the transitional period, along with detailed medical reviews unlike the previous reports, and found that preterm neonates had a higher plasma MIF concentration than late preterm or term neonates in the transitional period.[3,10,12,14,15,18] By comparing the concentration of MIF according to neonatal morbidity, we observed that higher MIF levels in the transitional period were significantly associated with the development of NEC in preterm neonates.
