Effectiveness of Pulmonary Rehabilitation in Exercise Capacity and Quality of Life in Chronic Obstructive Pulmonary Disease Patients With and Without Global Fat-Free Mass Depletion

OBJECTIVE To investigate the effectiveness of pulmonary rehabilitation (PR) in exercise capacity and quality of life in patients with chronic obstructive pulmonary disease (COPD) with and without global fat-free mass (FFM) depletion. DESIGN Retrospective case-control. SETTING Outpatient clinic, university center. PARTICIPANTS COPD patients (N=102) that completed PR were initially evaluated. INTERVENTION PR including whole-body and weight training for 12 weeks, 3 times per week. MAIN OUTCOME MEASURES St. George Respiratory Questionnaire (SGRQ), 6-minute walk distance (6MWD), and FFM evaluation applied before and after PR. RESULTS Patients were stratified according to their FFM status measured by bioelectric impedance. They were considered depleted if the FFM index was ≤ 15 kg/m(2) in women and ≤ 16 kg/m(2) in men. From the initial sample, all depleted patients (n=31) composed the FFM depleted group. It was composed predominantly by women (68%) with a mean age ± SD of 64.4 ± 7.3 years and a forced expiratory volume in 1 second of 33.6%=-13.2% predicted. Paired for sex and age, 31 nondepleted patients were selected from the initial sample to compose the nondepleted group. Improvement in the 6MWD was similar in these 2 groups after PR. Both groups improved SGRQ scores, although the observed power was small and did not allow adequate comparison between depleted and nondepleted patients. There was no difference between groups in weight change, whereas FFM tended to be greater in depleted patients. This increase had no correlation with the 6MWD or the SGRQ. CONCLUSIONS Benefits of PR to exercise capacity were similar comparing FFM depleted and nondepleted COPD patients. Although FFM change tended to be greater in depleted patients, this increase had no definite relation with clinical outcomes.

Sintomas respiratórios em trabalhadores de carvoarias nos municípios de Lindolfo Collor, Ivoti e Presidente Lucena, RS

OBJECTIVE To determine the prevalence of respiratory symptoms and smoking, as well as pulmonary function parameters among charcoal production workers in three cities in southern Brazil. METHODS This was an observational study including 67 individuals. Data were obtained by means of interviews and spirometry. RESULTS Of the 67 workers, 50 (75.0%) were male; mean age, 46.52 +/- 13.25 years; mean BMI, 25.7 +/- 3.85 kg/m(2); FEV1, 3.24 +/- 0.82 L (93.2 +/- 16.0% of predicted); FVC, 4.02 +/- 0.92 L (95.5 +/- 14.3% of predicted); and FEV1/FVC, 80.31 +/- 9.82. The most common upper airway symptoms were sneezing and nasal secretion-in 24 workers (35.82%)-whereas the most common lower airway symptom was cough-in 15 (22.38%).Of the 67 workers, 21 (31.34%) were smokers. In comparison with the nonsmokers, the smokers more often presented with cough (OR = 5.00; p = 0.01), nasal obstruction (OR = 3.50; p = 0.03), nasal itching (OR = 8.80; p = 0.01) and wheezing (OR = 10.0; p = 0.03), as well as presenting with lower FEV1 values (2.93 +/- 0.80 vs. 3.38 +/- 0.80 L; p = 0.04). We detected occupational rhinitis in 14 workers (20.85%), asthma in 4 (5.97%) and COPD in 4 (5.97%). CONCLUSIONS Respiratory symptoms and airflow reduction were more common in the smoking workers. Controlling the progression of the pyrolysis did not increase the prevalence of respiratory symptoms in the charcoal production workers studied.

The relationship between fat‐free mass index and pulmonary hyperinflation in COPD patients

Reduced fat‐free mass (FFM), a common finding in chronic obstructive pulmonary disease (COPD), may indirectly impact peak exercise capacity through a greater level of pulmonary hyperinflation. We aimed to investigate if FFM index (FFM/squared height) impacts exercise induced dynamic hyperinflation in COPD patients.
