Differences between neonatal units with high and low rates of breast milk feeding for very preterm babies at discharge: a qualitative study of staff experiences.

BMC Pregnancy Childbirth

December 2024

NIHR Policy Research Unit in Maternal and Neonatal Health and Care, National Perinatal Epidemiology Unit, Nuffield Department of Public Health, University of Oxford, Old Road Campus, Headington, Oxford, OX3 7LF, UK.

Background: Breast milk has significant benefits for preterm babies, but 'very preterm' babies are unable to feed directly from the breast at birth. Their mothers have to initiate and sustain lactation through expressing milk for tube feeding until their babies are developmentally ready to feed orally. There are wide disparities between neonatal units in England in rates of breast milk feeding at discharge.

Autophagy-dependent survival relies on a crucial oscillatory response during cellular stress. Although oscillatory behaviour is typically associated with processes like the cell cycle or circadian rhythm, emerging experimental and theoretical evidence suggests that such periodic dynamics may explain conflicting experimental results in autophagy research. In this study, we demonstrate that oscillatory behaviour in the regulation of the non-selective, stress-induced macroautophagy arises from a series of interlinked negative and positive feedback loops within the mTORC1-AMPK-ULK1 regulatory triangle.
