Summary
Mother's breast milk (MEBM) is the optimal nutrition for preterm infants, improving health outcomes. Banked donor breast milk (DEBM) may reduce risks for high-risk infants, but research is ongoing.
Area of Science:
- Neonatal nutrition
- Human milk bioactives
- Infant health outcomes
Background:
- Mother's expressed breast milk (MEBM) is recognized as the superior nutrition for preterm infants, linked to better short- and long-term health.
- The role of banked donor expressed breast milk (DEBM) is less defined but shows potential in mitigating necrotising enterocolitis and sepsis risks in high-risk preterm neonates.
- Human milk composition varies significantly, often necessitating nutrient fortification to support intrauterine growth rates.
Purpose of the Study:
- To highlight the importance of optimizing MEBM utilization in neonatal care.
- To explore the potential benefits and current limitations of DEBM for high-risk preterm infants.
- To identify key areas for future research in human milk science and application.
Main Methods:
- Literature review and synthesis of current evidence on MEBM and DEBM.
- Analysis of nutritional requirements and variability in human milk.
- Examination of microbial transmission risks and the impact of pasteurization.
Main Results:
- MEBM is associated with improved neonatal outcomes, emphasizing the need for resource allocation to maximize its use.
- DEBM may play a crucial role in preventing severe neonatal morbidities like necrotising enterocolitis and sepsis in vulnerable preterm populations.
- Nutrient fortification is frequently required due to natural variations in human milk composition.
Conclusions:
- Neonatal services must prioritize resources for optimizing MEBM use.
- DEBM warrants further investigation for its protective effects in high-risk preterm infants.
- Future research should concentrate on human milk's bioactive properties, critical exposure times, DEBM's role, and ensuring nutritional quality.

01:30Development of Human Microbiota
The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from the skin...
01:28Development of the Oral Microbiota
The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
01:22Development of Immunocompetence
The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
