Chronic respiratory symptoms, spirometry and knowledge of COPD among general population.

RATIONALE: Infradiagnosis of chronic obstructive pulmonary disease (COPD) may be related to the lack of knowledge about the disease and/or the scarce use of diagnostic procedures. This study analyses the frequency of respiratory symptoms and the knowledge about COPD in the general population, together with the use of spirometry in individuals at risk of COPD. POPULATION AND METHOD: A telephone survey was carried out in 6758 subjects older than 40 years, stratified by age, habitat (urban or rural) and region, screened by random-digit dialling. RESULTS: Up to 24% reported having at least one chronic respiratory symptom and 20.9% had a self-reported respiratory diagnosis. A total of 19.2% were active smokers and 40% had never tried to quit. Only 60% of the individuals with chronic symptoms had consulted a physician and, of them, only 45% had undergone spirometry. Spirometry was mentioned more frequently by subjects attended by pulmonologists than by GPs (67.6 vs. 28.6%; P<0.001). The term COPD was identified only by 8.6% of the participants. CONCLUSIONS: Many individuals with respiratory symptoms do not request medical attention and do not attempt to quit smoking. There is a lack of knowledge about COPD. Physicians should more actively inform about the disease and increase the use of spirometry for early detection.

Exercise training in mitochondrial myopathy: a randomized controlled trial.

Patients with mitochondrial myopathies (MM) usually suffer from exercise intolerance due to their impaired oxidative capacity and physical deconditioning. We evaluated the effects of a 12-week supervised randomized rehabilitation program involving endurance training in patients with MM. Twenty MM patients were assigned to a training or control group. For three nonconsecutive days each week, patients combined cycle exercise at 70% of their peak work rate with three upper-body weight-lifting exercises performed at 50% of maximum capacity. Training increased maximal oxygen uptake (28.5%), work output (15.5%), and minute ventilation (40%), endurance performance (62%), walking distance in shuttle walking test (+95 m), and peripheral muscle strength (32%-62%), and improved Nottingham Health Profile scores (21.47%) and clinical symptoms. Control MM patients did not change from baseline. Results show that our exercise program is an adequate training strategy for patients with mitochondrial myopathy.

Comparison of effects of strength and endurance training in patients with chronic obstructive pulmonary disease.

We determined the effect of different exercise training modalities in patients with chronic obstructive pulmonary disease, including strength training (n = 17), endurance training (n = 16), and combined strength and endurance (n = 14) (half of the endurance and half of the strengthening exercises). Data were compared at baseline, the end of the 12-week exercise-training program, and 12 weeks later. Improvement in the walking distance was only significant in the strength group. Increases in submaximal exercise capacity for the endurance group were significantly higher than those observed in the strength group but were of similar magnitude than those in the combined training modality, which in turn were significantly higher than for the strength group. Increases in the strength of the muscle groups measured in five weight lifting exercises were significantly higher in the strength group than in the endurance group but were of similar magnitude than in the combined training group, which again showed significantly higher increases than subjects in the endurance group. Any training modality showed significant improvements of the breathlessness score and the dyspnea dimension of the chronic respiratory questionnaire. In conclusion, the combination of strength and endurance training seems an adequate training strategy for chronic obstructive pulmonary disease patients.
