Environmental Health
Mold, Damp Buildings, Asthma, and Wheeze: Epidemiology
Meta-analyses link residential dampness and visible mold to ~30–50%+ higher odds of asthma and respiratory symptoms—odor counts as an exposure proxy.

Mold and Dampness in Schools and Childcare: Kids, Asthma, and Buildings
Damp schools raise respiratory risk for children. Fix water intrusion and ventilation; don’t rely on essential-oil diffusers or panic closures without assessment.

Mainstream Clinical Approach to Suspected Mold Illness
History, asthma/allergy workup, building fixes—and what not to order first.

Type 2 Inflammation Cytokines: IL-4, IL-5, IL-13, Alarmins & Biologic Targets
The shared cytokine program behind atopic dermatitis, allergic rhinitis, eosinophilic asthma, CRSwNP, and EoE—and why T2-high is not always “allergy.”

Sex Differences in Allergy & Autoimmunity: Pubertal Asthma Switch vs Female Autoimmune Bias
Boys dominate childhood asthma; women dominate adult severe asthma and most autoimmunity—different immune axes, not one slogan.

Fragrance, Asthma, and Respiratory Immune Effects
Scented products are common asthma and migraine triggers. Respiratory harm does not require proving classic EDC cancer headlines.

Environmental Health
Air Quality Indoor & Outdoor: PM2.5, Ozone, Allergens & Inflammatory Load
Pollution and indoor hazards drive airway oxidative stress and flares—source control, then ventilation, then filtration.

Environmental Health
ERMI, Air Cultures, and the Mold Testing Debate
ERMI is a research moldiness index—not a medical diagnosis. CDC still says fix moisture first.

Metabolic Health
Eczema, Skin Barrier, and the Atopic March
Barrier failure can sensitize through skin; oral exposure may tolerize. March is not destiny.

Allergic Rhinitis and Asthma: United Airways
One airway, shared T2 inflammation—ARIA asks about asthma in every rhinitis patient.

Damp Buildings and Asthma: Effect Sizes from Fisk, Mendell, and WHO
Meta-analyses link home dampness and mold to roughly 30–50% higher odds of respiratory outcomes. The intervention is moisture control—not essential oil theater.

Environmental Health
Mold & Damp Buildings: Health Evidence, Testing Limits & Remediation That Works
Dampness—not a magic spore number—is the risk signal. WHO and IOM link moldy buildings to respiratory disease; CDC does not recommend routine home mold testing. Fix water first.

Allergens & Inflammation: IgE, Type 2 Pathways, CRP & MCAS Claims
Allergy is not the same as systemic inflammation. Separates IgE from non-IgE disease, maps Type 2 pathways, covers Big 9 foods and LEAP, hs-CRP bands, MCAS triad criteria, and lifestyle adjuncts that do not replace epinephrine.
