The same substances that trigger allergy symptoms, such as pollen, dust mites and pet dander, may also trigger or worsen asthma signs and symptoms. In some people, skin or food allergies can cause asthma symptoms, according to TRICARE.

Assessment of revised recruitment standards for asthma in the Australian defence force.

Mil Med. 2014 Nov;179(11):1384-90

Authors: Ireland R, Waller M, MacKenzie A, Peake J, Nasveld P

Abstract
OBJECTIVE: To assess the impact of relaxed asthma recruitment standards adopted by the Australian Defence Force in 2007.
METHODS: A retrospective audit was conducted on clinical and administrative data for recruits, with and without mild asthma, in their first year of service.
RESULTS: There was no evidence that mild asthmatics experienced worse outcomes than nonasthmatic recruits. Mild asthmatics had fewer illnesses and restricted duty days and were less costly compared to other recruits. There was no difference in the rate of discharge (attrition) between those with and without mild asthma.
CONCLUSIONS: The revised recruitment standards for asthma in the Australian Defence Force have not resulted in unanticipated medical or administrative costs to the organization. Health and administrative outcomes differed little between mild asthmatics and nonasthmatic recruits in their first 12 months of service.

Cellular force that drives allergy and asthma can be blocked by interferon – Medical Xpress

Cellular force that drives allergy and asthma can be blocked by interferon

Asthma and allergies are both driven by an inappropriate activation of the immune system, primarily a subtype of white blood cells known as T helper 2 cells, or Th2 cells. These cells are normally responsible for defense against parasites, but are also

Emergence of airway smooth muscle mechanical behaviour through dynamic reorganisation of contractile units and force transmission pathways.

J Appl Physiol (1985). 2014 Jan 30;

Authors: Brook BS

Abstract
Airway hyper-responsiveness (AHR) in asthma remains poorly understood despite significant research effort to elucidate relevant underlying mechanisms. In particular, a significant body of experimental work has focussed on the effect of tidal fluctuations on airway smooth muscle (ASM) cells, tissues, lung slices and whole airways in order to understand the bronchodilating effect of tidal breathing and deep inspirations. These studies have motivated conceptual models that involve dynamic reorganisation of both cytoskeletal components as well contractile machinery. In this paper, a biophysical model of the whole ASM cell is presented which combines (i) crossbridge cycling between actin and myosin, (ii) actin-myosin disconnectivity, under imposed length changes, to allow dynamic reconfiguration of “force transmission pathways” and (iii) dynamic parallel-to-serial transitions of contractile units within these pathways, that occur through a length fluctuation. Results of this theoretical model suggest that behaviour characteristic of experimentally observed force-length loops of maximally activated ASM strips can be explained by interactions between the three mechanisms. Crucially, both sustained disconnectivity and parallel-to-serial transitions are necessary to explain the nature of hysteresis and strain-stiffening observed experimentally. The results provide strong evidence that dynamic rearrangement of contractile machinery is a likely mechanism underlying many of the phenomena observed at timescales associated with tidal breathing. This theoretical cell-level model captures many of the salient features of mechanical behaviour observed experimentally and should provide a useful starting block for a bottom-up approach to understanding tissue-level mechanical behaviour.
