Objective: Epidemiologic survey of respiratory diseases that cause hospital admissions at the Internal Medicine Service, Hospital Geral de Caxias do Sul (SCM-HG), a tertiary university hospital in the State of Rio Grande do Sul, Southern Brazil. Patients and methods: Retrospective study conducted at SCM-HG between November 1998 and November 1999. Data were obtained from medical records and included: a) major admission cause; b) associated diseases; c) sazonal variability; d) hospitalization length; e) mortality. Results: There were 1,200 admissions at SCM-HG, 228 (19%) caused by a respiratory disease. COPD (41.3%), pneumonias (29.8%) and bronchial asthma (9.6%) were the most prevalent. Fifty subjects (21.9%) presented comorbidity: cardiac failure (7.7%), systemic arterial hypertension (6.4%) and diabetes mellitus (4.4%). Pneumonias predominated between September and November, bronchial asthma frequency raised in October and November, and COPD prevailed from May to November. The admissions had an average duration of 10.4 ± 10 days. Twenty-six (11.4%) patients died. Conclusions: 1) Respiratory diseases were responsible for approximately 1/5 of the admissions. 2) COPD patients represented the biggest quota of admissions. 3) Patients with respiratory diseases stayed for a long time as compared with the others hospitalized patients (10.4 versus 7.7 days). 4) COPD, pneumonias and bronchial asthma behaved as expected regarding sazonal variability.

Objective: To clarify whether, in healthy individuals, practicing yoga can modify maximal inspiratory pressure and spirometric indices when compared with the practice of aerobic exercise. Methods: A controlled clinical trial. A total of 31 healthy volunteers were allocated to practice aerobic exercise (n = 15) or to practice yoga (n = 16). Those in the first group served as controls and engaged in aerobic exercise for 45-60 minutes, twice a week for three months. Those in the second group practiced selected yogic techniques, also in sessions of 45-60 minutes, twice a week for three months. Forced vital capacity, forced expiratory volume in one second and maximal inspiratory pressure were measured before and after the three months of training. Results: No significant alterations were seen in the spirometric indices. A slight, although not significant, improvement in maximal inspiratory pressure was seen in both groups. However, there was a significant difference, seen in both genders, between the absolute delta (final value minus baseline value) of maximal inspiratory pressure for the group practicing yoga and that obtained for the group engaging in aerobic exercise (males: 19.5 cm H2O versus 2.8 cm H2O, p = 0.05; females: 20 cm H2O versus 3.9 cm H2O, p = 0.01). Conclusion: Neither yoga nor aerobic exercise provided a statistically significant improvement in maximal inspiratory pressure after three months. However, the absolute variation in maximal inspiratory pressure was greater among those practicing yoga.

Objective: To assess the effect of psychotherapy on levels of anxiety and depression, as well as on quality of life and exercise capacity in patients with chronic obstructive pulmonary disease enrolled in a pulmonary rehabilitation program. Methods: A randomized, controlled, blind clinical trial was conducted involving 49 chronic obstructive pulmonary disease patients. Patients were randomized into three groups: those submitted to the complete pulmonary rehabilitation program, which included psychotherapy and an exercise regimen (group 1); those submitted to the program minus physical exercise (group 2); and those submitted to the program minus psychotherapy (group 3). The three groups underwent a 12-week treatment program. All patients were evaluated at baseline and at completion of the pulmonary rehabilitation program through four instruments: The Beck Anxiety Inventory, Beck Depression Inventory and St. George's Respiratory Questionnaire were applied. The distance walked-weight product was also calculated. Results: Statistically significant absolute improvements in exercise capacity were found for groups 1 and 2, although not for group 3 (p = 0.007, p = 0.008 and p = 0.06, respectively). In groups 1 and 2, levels of anxiety and depressions were also significantly reduced (group 1: p = 0.0000 and p < 0.0003; group 2: p = 0.0001 and p = 0.0014), and quality of life was significantly improved (p = 0.0007 and p = 0.002, respectively). Anxiety levels were also reduced in group 3 (p = 0.03), although levels of depression were not, and quality of life was unaffected. Conclusion: Psychotherapy sessions provided as part of a pulmonary rehabilitation program assist patients with chronic obstructive pulmonary disease in coping with disease-related limitations by reducing behavioral symptoms, especially depression, thereby influencing exercise capacity and health-related quality of life.

Study objectives: Multidisciplinary pulmonary rehabilitation has been the most suitable treatment for chronic obstructive pulmonary disease (COPD). This clinical trial studied the prevalence of anxiety and depression and the effect of a pulmonary rehabilitation program on anxiety and depression levels of 46 COPD patients (mean ± SD age, 62 ± 11 years; 34 men and 12 women). Design: The participants underwent a 12-week treatment program: 24 sessions of physical exercise, 24 sessions of physiotherapy, 12 psychological sessions and three educational sessions. All patients were evaluated at baseline and at completion of the rehabilitation program through three instruments: Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI) and 6- minute walking distance (Tcam6'). Results: Patients demonstrated significant statistical improvements, including reduced anxiety and depression, and increased endurance: BAI 16.4 ± 6.9 vs. 6.8 ± 5.3 (p < 0.001); BDI: 16.9 ± 8.7 vs. 7.5 ± 6.6 (p < 0.001); Tcam6": 335.7 ± 83.4 vs. 441.6 ± 100.8 (p < 0.05). Conclusions: COPD patients presented high prevalence of anxiety and depression levels. The pulmonary rehabilitation program was able to improve patient exercise performance, and to reduce anxiety and depression levels.

Objective: To assess the 24-month effects of a pulmonary rehabilitation program (PRP) on anxiety, depression, quality of life and physical performance of COPD patients. Methods: Thirty patients with COPD (mean age, 60.8 ± 10 years; 70% males) participated in a 12-week PRP, which included 24 physical exercise sessions, 24 respiratory rehabilitation sessions, 12 psychotherapy sessions and 3 educational sessions. All patients were evaluated at baseline (pre-PRP), at the end of the treatment (post-PRP) and two years later (current) by means of four instruments: the Beck Anxiety Inventory; the Beck Depression Inventory; Saint George's Respiratory Questionnaire; and the six-minute walk test (6MWT). Results: The comparison between the pre-PRP and post-PRP values revealed a significant decrease in the levels of anxiety (pre-PRP: 10.7 ± 6.3; post-PRP: 5.5 ± 4.4; p = 0.0005) and depression (pre-PRP: 11.7 ± 6.8; post-PRP: 6.0 ± 5.8; p = 0.001), as well as significant improvements in the distance covered on the 6MWT (pre-PRP: 428.6 ± 75.0 m; post-PRP: 474.9 ± 86.3 m; p = 0.03) and the quality of life index (pre-PRP: 51.0 ± 15.9; post-PRP: 34.7 ± 15.1; p = 0.0001). There were no statistically significant differences between the post-PRP and current evaluation values. Conclusions: The benefits provided by the PRP in terms of the indices of anxiety, depression and quality of life, as well as the improved 6MWT performance, persisted throughout the 24-month study period.
