Nasal Brush Identifies Genetic Biomarker of Asthma

Study flow for the identification of a nasal brush–based classifier of asthma by machine learning analysis of RNAseq data. One hundred and ninety subjects with mild/moderate asthma and controls without asthma were recruited for phenotyping, nasal brushing, and RNA sequencing of nasal brushings. The RNAseq data generated were then a priori split into development and test sets. The development set was used for differential expression analysis and machine learning (involving feature selection, classification, and statistical analyses of classification performance) to identify an asthma classifier that can classify asthma from no asthma as accurately as possible. The asthma classifier was then evaluated on eight test sets, including (1) the RNAseq test set of independent subjects with and without asthma, (2) two external test sets of subjects with and without asthma with nasal gene expression profiled by microarray, and (3) five external test sets of subjects with non-asthma respiratory

What is the classification systems for the severity of asthma?



Mild, mild to moderate, moderate and severe. It is not currently qualitatively classified.


mild, moderate, severe and life-threatening


Well i was told mine was servere at one point, then i grew out of it to mild, then very slight, then gone

what is the diffrence between asthma and COPD?

I know they are both respiratory diseases/ what are the diffrent classifications?


The difference is that COPD is a group of conditions, of which, asthma is one. Then there is Emphysema, Chronic Bronchitis, Bronchiectasis and others. Basically they all have problems with the airways, hence the term "obstructive". There are


COPD
Cigarette smoking is the leading cause of COPD. Most people who have COPD smoke or used to smoke. Long-term exposure to other lung irritants, such as air pollution, chemical fumes, or dust, also may contribute to COPD.
