For how we live.
A notice sets out how the agency intends to designate every US area for the 9.0 microgram 2024 fine-particle standard. Comments close 5 November; a court has ordered final designations by 6 February 2027.
A final action moves the Serious-area deadline for the Los Angeles-South Coast fine-particle area from December 2025 to December 2030, after California showed on-time attainment was impracticable. Effective 2 November.
The agency is repealing the carbon-capture-based standards at the heart of the 2024 rule, saying compliance-cost savings outweigh the emission cuts. It takes effect on 16 November 2026.
Guidelines now ask for an objective test before an asthma label is fixed to a child, and inhaled steroids remain the mainstay of control. Their benefit is real; so is a small, mostly temporary effect on growth.
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.
Sensors and reminder inhalers get patients to take more doses — one trial lifted adherence from 30% to 84%. That this translates into meaningfully better control is real but a smaller effect.
The ORBEX trial gave OM-85 or placebo to 822 young children at high risk of asthma. Wheezing lower-respiratory illnesses were, if anything, slightly more common on the drug.
A WHO data-set analysis shows how mobile and hospital teams split the load of hypertension, diabetes and epilepsy care during the war, while a separate study tracked dialysis capacity falling.
Most people who presented did not have diagnosed asthma. The investigation into the 2016 epidemic thunderstorm asthma event identified who was at risk, and it was not who health services expected.
Two birth cohorts totalling 9,801 children were sorted into eight developmental patterns. The classic progression was one of them, and one of the smallest.
A prospective study of 660 Syrian refugees living with noncommunicable diseases found symptom burden peaked in the hottest, dustiest period — with asthma and hypertension carrying the highest risk.
A placebo-controlled trial in 164 children reduced fine particles 64% and found no improvement in symptoms. A smaller crossover trial found a benefit, but only in children whose asthma was poorly controlled.
Adding an inhaled steroid to the as-needed inhaler roughly halved severe attacks against a short-acting reliever, at a fraction of the daily steroid exposure that maintenance therapy delivers.
Farm-raised children really are protected from asthma, and the mechanism has been traced to microbial exposure and innate immunity. What has not been shown is that household hygiene caused the allergy epidemic.
A global modelling study puts four million new paediatric asthma cases a year on ambient nitrogen dioxide — and finds that 92% of them occur below the WHO guideline concentration.
A 34-million-birth analysis maps how far smoke travels from the fires that make it. A companion review is blunt that what that exposure does, beyond the lungs, is still unsettled.
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.
Two February papers put respiratory virus activity into the models. One finds pollution effects amplified at peak influenza; the other finds them attenuated when rhinovirus is high.
Cedars-Sinai counted a 118% rise in general-illness visits and a 46% rise in heart attack visits over the 90 days after the fires started. Abnormal blood results more than doubled.
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.
