Influence of Chronic Obstructive Pulmonary Disease on Volatile Organic Compounds in Patients with Non-Small Cell Lung Cancer.

Introduction: The etiology of lung cancer is multifactorial. Exposure to tobacco smoke and the role played by the carcinogenic compounds that it contains would explain the common association between lung cancer and chronic obstructive pulmonary disease (COPD), which is closely linked to tobacco use. In both diseases, sustained inflammation is caused by increased oxidative stress (for example, lipid peroxidation).

Factors related with the higher percentage of hospitalizations due to asthma amongst women: the FRIAM study.

Introduction: The reason why there is a higher hospitalization rate due to asthma exacerbations amongst women is unclear. The objective of this study is to explore the possible causes that may explain this fact.

Methods: A multi-center, prospective study including asthma patients hospitalized in the pulmonary medicine departments during a two-year period.
