Osmolality of fortified human milk with contemporary human milk fortifiers

open access: yesNutrition in Clinical Practice, EarlyView.
Abstract Background Human milk fortification is critical to support preterm infant growth. Human milk fortifed to caloric densities above manufacturers’ recommendations are often necessary to achieve adequate growth. Fortified milk may be prepared 12–24 h before feeding, although practice variations exist.

Growth and human milk intake outcomes from postdischarge feedings among very‐low‐birth‐weight preterm infants: A systematic review

open access: yesNutrition in Clinical Practice, EarlyView.
Abstract Background Preterm infants of <34 weeks gestation or <1500 g are at risk for postnatal growth failure and often require nutrition support after discharge. Despite expert recommendations for postdischarge human milk (HM) fortification or nutrient‐enriched formula feeding, the effects of current feeding strategies on growth and HM intake remain ...
