...with $800 million cuts to "EDI" research used as an example. Yet such "savings" would be enormously costly while eroding the right of all human beings to live healthy lives.

Disease strikes all, regardless of wealth, appearance or political beliefs. This has led to bipartisan support for the NIH+ other agencies (e.g. CDC/EPA) whose work has led to preventing+ treating previously fatal diseases. The current argument for cutting funding is that it will save money...

...Native Americans. As other examples, asthma, COPD, CF and lung cancer are more common/more likely to lead to death/disability in some groups due to environment (e.g. pollution), >susceptibility (e.g. smoking in women) and lack of group-effective medications (e.g. for CF) or healthcare access.

Does cutting funding for health disparities research save money? Health disparities affect people facing barriers to health due to their race/ethnicity; SES; gender; or other traits linked to discrimination. COVID-19 caused more deaths in the poor+ Blacks+ Latinos... @atscommunity.bsky.social

These findings expand on our prior results for T2-high asthma using blood markers, while those for T17-high asthma further suggest that ETV may affect asthma through neutrophilia and reduced corticosteroid response. @upmc.com @atscommunity.bsky.social @ats-assemblies.bsky.social #StopGunViolence

Is violence exposure (ETV) associated with specific asthma endotypes? In an @annalsats.bsky.social paper, K Gaietto et al used nasal epithelial transcriptomics (2025 @jama.com) to show that ETV/gun violence are linked to T2- and T17-high asthma in Puerto Ricans. doi: 10.1513/AnnalsATS.202502-151OC

T2-low asthma (T2LA) is often thought rare in kids. In 4,284 U.S. youths, Dr. Han shows that, cons. with prior findings (JAMA 2025), T2LA prev. (by eos+ FeNO) is 46-60%. Older age, female sex, overweight+ SHS were linked to T2LA. doi: 10.1016/j.jaip.2025.04.040 @upmc.com @atscommunity.bsky.social

This #MemorialDay, we honor the brave individuals who gave their lives in service to our country.

As we remember their sacrifice, we also recognize the impact of military service on respiratory health—and recommit to advancing care and research for all who serve.
