Researchers at Mount Sinai have found that exposure to per- and polyfluoroalkyl substances (PFAS), commonly known as "forever chemicals," during pregnancy and early life is associated with increased intestinal inflammation during childhood.
Published in Clinical Gastroenterology and Hepatology, the study measured PFAS concentrations in maternal blood collected during pregnancy, umbilical cord blood, and newborn dried blood spots, then followed children for up to 11 years. Higher PFAS mixture levels were associated with higher fecal calprotectin levels, a sensitive biomarker of intestinal inflammation, later in childhood. Both legacy PFAS compounds and newer replacement PFAS were linked to these findings, suggesting a broad range of these chemicals may influence children's gut health.
The findings provide new evidence that environmental exposures during critical stages of development may influence long-term intestinal health and future inflammatory bowel disease (IBD) risk.

ALT A diagram illustrates research on 5,229 participants from 16 U.S. cohorts. It shows a pregnant person over a U.S. map, with test tubes indicating serum or plasma taken during pregnancy. Several chemicals are listed: PFOA, PFOS, PFHxS, PFNA, PFDA, MeFOSAA. An arrow points to "Gestational diabetes" and "Fasting glucose" with a question mark. The Environmental influences on Child Health Outcomes (ECHO) logo appears on the right.

In a series of meta-analyses conducted by @IcahnMountSinai researchers, PFAS were associated with several glycemic markers, including
📌 HOMA-IR
📌 HOMA-beta
📌 fasting glucose
📌 fasting insulin

The Icahn School of Medicine at Mount Sinai is the first school in the nation to grant all medical and graduate students access to OpenAI’s educational platform — leading the way in integrating AI into medical education.
Fifth year MD, PhD student Joy Jiang recently sat down with CBS Mornings to talk about what this means for the future of healthcare. Follow the link to watch the full feature: youtube.com/watch?v=BSsxuJjp…
Truly honored and excited to step into new roles at Mount Sinai, driving forward public health research and education —
at a time when it matters most.

Researchers at the Icahn School of Medicine at Mount Sinai studied the role of exposure to environmental chemicals in pregnancy on the liver health of mothers and their newborns.
@DaniaValvi @Sandra_India_A
🚨Our new study coming out in the @JHepatology 🚨
Folic acid (and B12 vitamin?) in pregnancy could help reduce the impacts of air pollution and environmental chemical exposures on #liver health for both mother and child!
