What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now

Summary

This study looks at 40 premature babies (born before 30 weeks) to see if viruses in their lungs and gut during the first three weeks of life are linked to a serious lung condition called bronchopulmonary dysplasia (BPD). Researchers will collect throat and stool samples to track viral changes and compare babies who develop BPD with those who don't. The goal is to better understand how early viral exposure might influence lung health, which could lead to new ways to predict or prevent BPD.
