HHS-OASH-2026-0397-2911 https://www.regulations.gov/comment/HHS-OASH-2026-0397-2911 I am writing with praise from Ireland on this vital work for investigation due to my interest in this area after my young child suffered a huge regression after moving next door to an airport. I now know this to be calls “pans” I am hoping that with the progression in this field of study, other countries will be inspired to “catch up” with modern and current research , and even if they choose not to, breakthrough will be possible for the millions of concerned mothers and fathers paying attention to this administration. Thank you
