#386 - 🟢 HOT TOPICS 2025 COVERAGE - How Does Maternal Air Pollution Exposure Affect the Infant Microbiome?

Send us Fan MailDr. Divya keerthy (New York Presbyterian Queens/Weill Cornell Medicine) and Dr. Katherine Nyman (UCSD/Rady Children's, San Diego) discuss their Hot Topics conference experience. Keerthy presents research on prenatal polycyclic aromatic hydrocarbon exposure measured via backpack monitors and silicone wristbands during the third trimester. Her longitudinal study tracked infant microbiome at three time points over six months, identifying two air pollutants affecting microbiome development. Nyman highlights interest in the Tiny Baby collaborative, particularly PDA management challenges in extremely premature infants. Both emphasize the value of Hot Topics' evidence-based sessions including "green and rotten apples" that stress-test current practices. They note the conference's focus on moderate preemies (32-34 weekers) who comprise 80% of NICU populations yet receive less research attention.
