Abstract: A sensor apparatus may include a conduit structure including an inner surface defining a conduit extending through an interior of the conduit structure, an inlet structure coupled to an end of the conduit structure, and a plurality of sensor devices in hydrodynamic contact with the conduit. The inlet structure may couple with an outlet end of an external tobacco element to hold the outlet end of the external tobacco element in fluid communication with an inlet opening of the conduit structure, such that the conduit structure may receive a generated aerosol from the external tobacco element at the inlet opening, and draw an instance of aerosol through the conduit towards an outlet opening. The instance of aerosol may include at least a portion of the generated aerosol. Each sensor device may generate sensor data indicating a pressure of the instance of aerosol through a separate portion of the conduit.

Abstract: Described herein are a group of 1,013 genes and 1 phenotypic variable are identified as candidate predictors that differentiated smokers (current or former) with or without COPD. The full predictor set can be reduced to a nine-gene classifier (IL6R, CCR2, PPP2CB, RASSF2, WTAP, DNTTIP2, GDAP1, LIPE, and RPL14) with similar performance. Also described herein is the use of the full predictor set and the reduced nine gene set in methods of diagnosing lung disease or an increased risk of developing lung disease, such as COPD, in a subject. Also described herein is the use of the full predictor set and the reduced nine gene set in methods of providing a prognosis for a subject with lung disease, such as COPD.
