Oasys and Occupational Asthma

This website contains information on Occupational Asthma and a free multi award winning computer program called OASYS, which is used to help diagnose Occupational Asthma from serial peak flow records. Oasys shows further information and downloads for the Oasys program. References is a searchable database of more than 5000 published papers in the field of occupational asthma. Causes shows some of the causes of occupational asthma. The Shield scheme reports some statistics for occupational asthma, mainly in the West midlands region, UK. BOHRF shows the evidence based occupational asthma guidelines for the UK. The interactive Case Histories are a learning resource for interested health professionals. There are also Medics, Specialists, Employers and Worker sections.

Comments for the paper: "Chronic occupational exposures to irritants and asthma in the CONSTANCES cohort", 2024, Occup Environ Med
A difficult study from which to draw conclusions about irritant induced occupational asthma, which is not defined and seems to include many of the agents (particularly cleaning agents and biocides) for which there are positive specific challenge tests (the SIC data is ignored in this publication). The odds ratios for current asthma were very low, both for high molecular weight sensitisers (1.05-1.16) and their irritant group (1.1), with no increased risk for low molecular weight sensitisers (probably mainly isocyanates). The data on solvent exposure is difficult to interpret. I wonder whether the use of the JEM is not sufficiently specific to identify the known increased risks for occupational asthma from many high and low molecular weight agents which are more likely acting as sensitisers.

Can Modalert and asthma medicine be taken together?
Modalert is a central nervous system brain stimulant that resolves the problem of excessive sleepiness by promoting wakefulness. It causes an increase in certain hormones in the brain, resulting in better brain functions and cognitive abilities. Now to question is can asthma patients take Modalert. As we know asthma is a condition that creates breathing issues, therefore, Modalert might not be suitable for them. Since, Modalert can cause shortness of breath and increases heartbeat. Thus, asthma patients must take caution while taking Modalert and must consult and follow experts’ advice. More information about Modalert- https://healthnaturo.com/product/Modalert200mg/

The Website

This website is run by the Oasys research group, part of the Midland Thoracic Society, UK. We are an independent group of clinicians and researchers, and run a clinical service for workers with occupational lung disease as part of the British National Health Service. We have developed the Oasys program to help ourselves and others in the diagnosis of occupational asthma. We have no specific funding, relying on research grants and the enthusiasm of our group. The website is written by Cedd Burge, who receives some funding from the group. The group meets every Friday evening after the occupational lung disease clinic, as shown below.



As a casual user of this site (without logging in or registering) you can view all the information and use all the contact pages. Registered and logged in users (registering is free and we won't abuse your email) can download and use the Oasys program, ask and reply to questions in the forums, leave comments, add new references, add abstracts and full text links to existing references, answer questions in the case histories and provide evidence and suggest questions for future evidence based guidelines.

If you would like to be added to the list of known authors or collaborators then please register with the website (if you have not already done so) and then get in touch from the contact page. Once we have set the page up you will be able to edit it yourself and indicate which references you have written. Your picture will then be displayed along with each of these references. If you are already in these lists and would like to edit your page then please register with the website and then get in touch from the contact page.
