Is this trial a fit for you?

Likely a good fit

Ideal candidates are full-term infants born via cesarean section whose mothers intend to breastfeed.

Probably not a fit

Patients who do not intend to breastfeed or have significant congenital malformations may not benefit from this study.

What this trial studies

This pilot randomized controlled trial aims to evaluate the effects of donor human milk (DHM) compared to formula supplementation on the gut microbiome of full-term infants born via cesarean section. The study will also assess health outcomes related to sleep and growth, as well as maternal outcomes such as depression and breastfeeding self-efficacy. By randomizing infants requiring supplementation, the study seeks to establish causal relationships between feeding type and microbiome development, enhancing the potential for implementing DHM in clinical practice. Conducted in a postpartum hospital setting, this research aims to provide pragmatic insights into the benefits of DHM for both infants and mothers.

Why it matters

Potential benefit: If successful, this study could improve the gut health and overall well-being of infants born via cesarean section.

How similar studies have gone: While the use of donor human milk is gaining attention, this specific approach in cesarean-born infants is novel and has not been extensively tested.
