Interval hypoxic training improves autonomic cardiovascular and respiratory control in patients with mild chronic obstructive pulmonary disease.

Objectives: Chronic obstructive pulmonary disease (COPD) is associated with cardiac autonomic nervous system dysregulation. This study evaluates the effects of interval hypoxic training on cardiovascular and respiratory control in patients with mild COPD.

Methods: In 18 eucapnic normoxic mild COPD patients (age 51.

Respiratory symptoms and bronchoalveolar lavage abnormalities in molybdenum exposed workers.

Study Objectives: To detect an adverse effect of chronic inhalative molybdenum trioxide (MoO3) exposure in a group of symptomatic MoO3 exposed workers.

Participants: 43 inhalatively MoO3 exposed workers of a metal plant and 23 non-exposed controls were included in this study. Among the workers, 33 suffered from respiratory symptoms while 10 individuals were asymptomatic.
