Responses to inhaled long-acting beta-agonist and corticosteroid according to copd subtype

TiO2 is described as fine if it is 100-3,000 nm [25] , [26] , [27] and ultrafine if it is smaller than 100 nm. [28] Findings show that commercial pigments contain almost no particles smaller than 100 nm. [29] , [30] Scattering of light by TiO2 is maximized in particles that are 200-300 nm in diameter. [31] Studies have shown that inhalation exposure of TiO2 particles in cosmetics are predominately inhaled as clusters and do not reach the alveoli (the part of the lungs where oxygen is exchanged). [32] The findings demonstrated that a user would be exposed to nanomaterials that are larger than 1-100 nanometers. [33] MORE...

We are focused in the development of novel technologies for assessing alveolar macrophage modulation and inflammatory responses during regulatory safety testing of new inhaled medicines. Outcomes will include important new insights into macrophage responses (including species differences) based on  in vitro  and enhanced,  in vivo   evaluations which require fewer animals. ‘Foamy’ macrophage (FM) responses are commonly observed during nonclinical development, but are difficult to interpret. We have shown that the FM presentation can be modelled  in vitro , differentiated using an FM toolkit which we developed in pilot studies, and characterised based on functional and phenotypic responses (temporal and dose-related) to different materials. Based on these high-throughput methods, we will develop predictive algorithms to prevent unsuitable compounds entering nonclinical testing. Biomarkers and further insights into macrophage responses will be sought using (i) state-of-the-art (and beyond) mass spectroscopy imaging of single cells and tissue slices, (ii) targeted transcriptomics/toxicological pathway analysis, (iii) parallel evaluation of two non-invasive monitoring techniques for longitudinal studies: exhaled breath analysis and CT imaging. These approaches have been selectively combined by an expert multi-disciplinary consortium which, with the advice and in-kind contributions of industry sponsors, will deliver a high-value solution to the Inhalation Translation Challenge. Commercialisation of the technologies will ensure their widespread availability to reduce animal use whilst improving the amount and  in vivo  usefulness of data from mandatory testing. Vigorous stakeholder engagement will ensure the Challenge solutions have industry and regulatory acceptance and are disseminated effectively.

I’ve used small doses (as needed) of plantain tincture for respiratory issues caused or aggravated by particulate matter – not so much experience with smoke, but lots for carpenters, contractors, road workers, natural builders. Plantain seems to cause the mucous membranes to moisten, loosening irritants that were inhaled, coat the lung tissue and dry it out. Productive hacking (err… expectoration) oft ensues. Blends quite well with new england aster and mullein leaf. Nice with ragweed for upper respiratory woe, too.

The growth of children and adolescents receiving orally inhaled corticosteroids, including QVAR, should be monitored routinely (., via stadiometry). If a child or adolescent on any corticosteroid appears to have growth suppression, the possibility that he/she is particularly sensitive to this effect should be considered. The potential growth effects of prolonged treatment should be weighed against clinical benefits obtained and the risks associated with alternative therapies. To minimize the systemic effects of orally inhaled corticosteroids, including QVAR, each patient should be titrated to his/her lowest effective dose [see Dosage and Administration ( )] .
