Sensitizer-induced occupational asthma is an immunologic form of asthma which occurs due to inhalation of specific substances (i.e., high-molecular-weight proteins from plants and animal origins, or low-molecular-weight agents that include chemicals, metals and wood dusts) and occurs after a latency period of several weeks to years.
An asthmagen is a substance that can cause asthma in exposed people. [1] Workplace asthmagens induce what is called occupational asthma. [2] [3] A 2016 study of occupational asthmagens in Australia identified 277 in 27 groups, including ammonia, latex, pesticides and wood dust. [4]
Asthma is a respiratory disease that can begin or worsen due to exposure at work and is characterized by episodic narrowing of respiratory airways. Occupational asthma has a variety of causes, including sensitization to a specific substance, causing an allergic response; or a reaction to an irritant that is inhaled in the workplace.
Occupational asthma – an estimated 2% to 5% of all asthma episodes may be caused by exposure to a specific sensitizing agent in the workplace. Nocturnal asthma is a characteristic problem in poorly controlled asthma and is reported by more than two-thirds of sub-optimally treated patients.
Occupational dust exposure occurs when small particles are generated at the workplace through the disturbance/agitation of rock/mineral, dry grain, timber, fiber, or other material. When these small particles become suspended in the air, they can pose a risk to the health of those who breath in the contaminated air.
Roblox occasionally hosts real-life and virtual events. They have in the past hosted events such as BloxCon, which was a convention for ordinary players on the platform. [98] Roblox operates annual Easter egg hunts [99] and also hosts an annual event called the "Bloxy Awards", an awards ceremony that also functions as a fundraiser. The 2020 ...
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.
Occupational health inequalities refer to differences in occupational injuries and illnesses that are closely linked with demographic, social, cultural, economic, and/or political factors. [189] Although many advances have been made to rectify gaps in occupational health within the past half century, still many persist due to the complex ...
