I do point out that the last graph shows risk of lifetime exposure only AT the Action Level
The main histopathologic findings that have been described in association with vaping-associated lung injury, are those of organizing acute lung injury, including organizing pneumonia, diffuse alveolar damage, acute fibrinous pneumonitis and eosinophilic pneumonia.4 Foamy macrophages, were described in a subset of cases, however, features of exogenous lipoid pneumonia have not been documented.5 Peribronchial inflammation, and rarely, features similar to hypersensitivity pneumonitis, have also been reported Advertisement Many patients with mild disease will improve with cessation of vaping alone
An aliquot of cells (210 4 cells) was prepared by centrifugation (Cytospin 11, Shandon Instruments, Pittsburgh, PA), air-dried, fixed in 4% paraformaldehyde in PBS, and stained using Diff-Quik (Dade Behring, Newark, NJ)
The American Lung Association tracks the data
The study does highlight that 3.5 years is a short period of time to follow up for possible harm
