Necrotizing enterocolitis (NEC) is the most common gastrointestinal emergency in newborn premature infants. Clinical studies show increased incidence of NEC in premature infants with enteral formula feeding; however, pathogenesis remains unclear. To identify the NEC-related proteins for molecular mechanisms, we applied proteomics analysis to characterize changes in the protein expression profile of newborn premature piglet intestines with NEC developed after enteral formula feeding for 24 h. Changes in protein expression were identified using 2-dimensional gel electrophoresis and peptide mass fingerprinting with MS as well as western blotting analysis. Nineteen differentially expressed proteins were identified and these have roles in oxidative stress, chaperone, signal transduction, protein folding and degradation, oxygen transport, signal transduction, and energy metabolism. Proteins with increased levels include manganese-containing superoxide dismutase and hemoglobin subunit and proteins with decreased expression include sorbitol dehydrogenase, mitochondrial aldehyde dehydrogenase 2, glucose-regulated protein 75, CRY protein, snail homolog 3, thyroid hormone-binding protein precursor, and DJ1 (Parkinson's disease 7) etc. The data provided novel mechanistic insights into the pathogenesis of NEC and the insults of a formulated diet to the premature gut.

The process that begins around the 6th month of life and continues until the 24th month is called the complementary feeding period. During this period, infants and children start receiving foods that complement breast milk or formula for the first time. The psychosocial factors the infants and children encounter during this period may affect their growth and health in later life.

Aim: The aim was to investigate feeding type at discharge; exclusively breastfeeding (EBF), mixed breastfeeding (MBF), and formula milk feeding (FMF), factors associated with feeding type, and changes in weight-for-age z-score (ΔWAZ) in infants admitted to Danish neonatal units.
Methods: Using data from the Danish National Quality Database for Births and the Danish Newborn Quality Database, we included 8639 mother-infant dyads admitted ≥5 days between February 2019 and December 2021. We used logistic regression to investigate associations between maternal and infant factors and feeding type, and descriptive statistics to describe ΔWAZ and feeding type at discharge.

Introducing commercial milk formula (CMF) as prelacteal feeds can disturb exclusive breastfeeding and shorten breastfeeding duration. However, the prelacteal feeding of CMF has been growing alongside its increasing sales in Indonesia. This study examined predictors of the CMF feeding in the Malang and Sidoarjo districts of Indonesia.

Pasteurized donor human milk must be provided when mother's own milk (MOM) is not available for preterm infants. There are concerns that human milk banks (HMBs) and the use of donor milk may potentially reduce breastfeeding rates. To compare feeding during hospitalization and at discharge before and after the opening of a HMB and to evaluate the proportion of milk provided by mothers of premature babies, comparing the intake of MOM in infants born of donor and no donor mothers.

In the UK, up to 700 people with HIV give birth annually; the majority are Black African migrant cisgender women. Infant-feeding decisions for parents with HIV are complex, requiring parents to weigh-up the small risk of HIV transmission via breastmilk and UK guidelines recommending formula milk, against strong personal and societal expectations to breastfeed. We explored this situation in a qualitative study.
