Trained dogs were asked to sniff out a study group that included lung cancer patients, chronic obstructive pulmonary disease (COPD) patients, and healthy volunteers.
For example, another study published last month demonstrated that patients with chronic obstructive pulmonary disease were more likely to follow a fitness program using the Nintendo Wii than a traditional fitness program.
The study of a sustained release oral formulation of the synthetic form of prostacylin showed that patients treated for pulmonary arterial hypertension did not achieve a statistically significant improvement in how far they were able to walk within six minutes by week 16 of the trial.
