For how we live.
The federal program enrols nearly 140,000 responders and survivors, most certified for a 9/11-related illness. Cohort data show a heavy, still-growing burden — and hint the program itself lowers mortality.
Twenty-five years of cohort data show the alkaline dust caused an acute cough syndrome and a real, largely permanent drop in lung function, graded by how much each person breathed.
Two vaccines cut RSV lower-respiratory illness in older adults by roughly two-thirds to four-fifths in their pivotal trials. US guidance now recommends them for everyone 75 and older and for high-risk adults from 50.
In women 41 to 50, late perimenopause and postmenopause brought measurable declines in lung volume, with postmenopausal women losing up to 310 mL of FEV1. HIV status didn't change the pattern.
Health agencies conclude there is enough evidence to tie indoor dampness and mould to respiratory symptoms and asthma. Controlling the water source, not identifying the species, is what the evidence points to.
Cooking with gas emits nitrogen dioxide indoors, and pooled studies tie it to a higher risk of childhood asthma. One US analysis attributes about one in eight cases to gas stove use — an association, not a proven cause.
A new analysis of 198 cities finds 87% have a longer freeze-free growing season than in 1970 — up to 100 extra days in Reno — pushing pollen exposure further into the calendar.
A November systematic review screened 120 publications and found five eligible papers, all from the US and Canada. All pointed the same way; none could be pooled with the others.
