Vulnerability is the summation of all risk and protective factors that ultimately determine whether an individual or subpopulation experiences adverse health outcomes when an exposure to an ...

Asthma phenotyping and endotyping has emerged as a novel approach to asthma classification inspired by precision medicine which separates the clinical presentations of asthma, or asthma phenotypes, from their underlying causes, or asthma endotypes. The best-supported endotypic distinction is the type 2-high/type 2-low distinction.
Thunderstorm asthma (also referred to in the media as thunder fever or a pollen bomb [1]) is the triggering of an asthma attack by environmental conditions directly caused by a local thunderstorm.
