What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now

Summary

This study looked at 55 very premature babies (born at 28-30 weeks) to see if natural mother's milk or pasteurized milk better helps their guts mature. Researchers measured bioactive molecules in the milk and tracked gut development during small feedings. The goal was to understand if pasteurization changes the milk's benefits for these fragile infants.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
natural or pasteurized mother's milk
What this could lead to
If successful, this could help doctors understand whether natural milk better supports gut development in very premature babies.
What could go wrong
This is a small, completed observational study, not a treatment trial. Results may not lead to changes in care without larger studies.

This is an AI summary of the original study and may miss details. Read our disclaimer.
