Summary
Delayed breast milk expression in mothers of preterm infants is linked to lower rates of breastfeeding at discharge. Improving milk expression practices is crucial for promoting breastfeeding success in this vulnerable population.
Area of Science:
- Neonatal care
- Lactation science
- Infant nutrition
Background:
- Mothers of preterm infants often face challenges with breast milk expression.
- A low rate of exclusive breastfeeding is observed in preterm infants upon hospital discharge.
- This study investigates factors contributing to low breast milk utilization in preterm infants.
Purpose of the Study:
- To test the hypothesis that milk expression factors are responsible for the low breast milk rate in preterm infants at discharge.
- To identify risk factors associated with not providing breast milk to preterm infants at discharge.
Main Methods:
- Retrospective analysis of preterm infants (born before 33 weeks gestational age) between March 2005 and June 2014.
- Nutritional evaluation at discharge to determine infant feeding method (breast milk, formula, or mixed).
- Multivariate logistic regression analysis to identify risk factors for formula feeding.
Main Results:
- Data from 297 preterm infants were analyzed; 8.8% received breast milk, 33.3% received formula, and 57.9% received a mix at discharge.
- The time to first milk expression (in hours) was identified as a significant risk factor for the formula group (adjusted odds ratio: 1.06; 95% CI: 1.02-1.09; p=0.002).
- Delayed initiation of milk expression was associated with a lower likelihood of providing breast milk at discharge.
Conclusions:
- Delayed first milk expression is a significant risk factor contributing to the low rate of breast milk utilization in preterm infants at discharge.
- Interventions aimed at improving and expediting milk expression practices are recommended to enhance breastfeeding rates.
- Promoting timely milk expression is essential for supporting breastfeeding in mothers of preterm infants.

01:30Development of Human Microbiota
15
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...

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,...

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.

A thorough assessment of respiratory health is paramount in clinical settings to identify and manage respiratory distress and ensure adequate oxygenation. This article elaborates on the critical aspects of respiratory evaluation, including airway assessment, skin color examination, and the observation of accessory muscle use, which are integral to effectively diagnosing and managing patients with respiratory conditions.

The female breast is a hemispheric projection of variable size positioned anterior to the pectoralis major and serratus anterior muscles. A fascia layer composed of dense, irregular connective tissue connects it to these muscles.
Each breast features a pigmented projection known as the nipple, through which milk emerges via closely spaced openings of ducts, referred to as lactiferous ducts. Surrounding the nipple is a circular pigmented area of skin named the areola, which appears rough due to...

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...
