Effects of early energy intake on neonatal cerebral growth of preterm newborn: an observational study
Abstract Current guidelines for preterm newborns recommend high energy nutrition soon after birth in order to limit growth retardation. However, long-term effects of this nutritional approach are still debated, and it has been demonstrated that cerebral growth depends on protein intake in early life...

Abstract Current guidelines for preterm newborns recommend high energy nutrition soon after birth in order to limit growth retardation.

We aimed at evaluating the impact of energy intake on cerebral growth in preterm neonates early in life. We included preterm newborns with gestational age < 32 weeks or birth weight (BW) < 1500 g.
