Objective: To evaluate the health-related quality of life of patients submitted to resection of the pulmonary parenchyma due to neoplasia. Methods: The Medical Outcomes Study 36-item Short-Form Health Survey was used to evaluate patients in the preoperative period and on postoperative days 30, 90 and 180. We used the GEE statistical model, in which the dependent variable (quality of life) changes for each patient over the course of the evaluation. Independent variables were gender, age, educational level, type of surgery, radiotherapy, chemotherapy, forced vital capacity and 6-minute walk test. The level of significance adopted was 5%. Results: The final study sample comprised 36 patients, 20 of whom were men. Of those 36 patients, 17 were submitted to lobectomy, 10 to pneumonectomy, 6 to segmentectomy, and 3 to bilobectomy. Chemotherapy was used in 15 patients, radiotherapy in 2, and a combination of radiotherapy and chemotherapy in 2. Improved quality of life was seen in the following domains: social (on postoperative day 90); physical/functional (some patients presenting better forced vital capacity and 6-minute walk test performance); and physical (in patients undergoing smaller resections). Lowered quality of life was seen in the following domains: social (for female patients); physical/social (resulting from radiotherapy, chemotherapy or both); and physical/functional (by postoperative day 30). Conclusions: It is important that studies evaluating the various determinants of quality of life, as well as the impact that cancer treatment modalities have on such variables, be conducted. The knowledge provided by such studies can contribute to improving the quality of life of patients undergoing pulmonary resection due to neoplasia.

Objective: To evaluate the effects that pulmonary resection has on pulmonary function and quality of life (QoL) in patients with primary or metastatic lung cancer. Methods: This was a prospective cohort study involving all patients submitted to pulmonary resection for cancer between September of 2006 and March of 2007 at the A. C. Camargo Hospital in São Paulo, Brazil. Patients underwent spirometry in the preoperative period and at six months after the surgical procedure. After a postoperative period of six months, the patients completed an overall QoL questionnaire (the Medical Outcomes Study 36-item Short-form Health Survey) and another one, specific for respiratory symptoms (the Saint George's Respiratory Questionnaire). The scores obtained in our study were compared with those previously obtained for a general population and for a population of patients with COPD. Results: We included 33 patients (14 males and 19 females), ranging in age from 39 to 79 years. All of the patients, smokers and nonsmokers alike, presented significant worsening of pulmonary function. The mean scores on the overall QoL questionnaire were approximately 5% lower than those obtained for the general population. The scores of various domains of the symptom-specific QoL questionnaire were 50-60% lower than those obtained for the general population and approximately 20% higher than those obtained for the population with COPD. Conclusions: Pulmonary resection has a direct negative impact on pulmonary function and QoL, especially on the QoL related to aspects directly linked to pulmonary function. We highlight the importance of preoperative assessment of pulmonary function in patients undergoing pulmonary resection, in order to predict their postoperative evolution.

Objective: To evaluate quality of life according to the level of asthma control and degree of asthma severity in children and adolescents. Methods: We selected children and adolescents with asthma (7-17 years of age) from the Pediatric Pulmonology Outpatient Clinic of the State University of Campinas Hospital de Clínicas, located in the city of Campinas, Brazil. Asthma control and asthma severity were assessed by the Asthma Control Test and by the questionnaire based on the Global Initiative for Asthma, respectively. The patients also completed the Paediatric Asthma Quality of Life Questionnaire (PAQLQ), validated for use in Brazil, in order to evaluate their quality of life. Results: The mean age of the patients was 11.22 ± 2.91 years, with a median of 11.20 (7.00-17.60) years. We selected 100 patients, of whom 27, 33, and 40 were classified as having controlled asthma (CA), partially controlled asthma (PCA), and uncontrolled asthma (UA), respectively. As for asthma severity, 34, 19, and 47 were classified as having mild asthma (MiA), moderate asthma (MoA), and severe asthma (SA), respectively. The CA and the PCA groups, when compared with the NCA group, showed higher values for the overall PAQLQ score and all PAQLQ domains (activity limitation, symptoms, and emotional function; p < 0.001 for all). The MiA group showed higher scores for all of the PAQLQ components than did the MoA and SA groups. Conclusions: Quality of life appears to be directly related to asthma control and asthma severity in children and adolescents, being better when asthma is well controlled and asthma severity is lower.

Objective: To test a prediction model for sleep apnea based on clinical and sociodemographic variables in a population suspected of having sleep disorders and submitted to polysomnography. Methods: We included 323 consecutive patients submitted to polysomnography because of the clinical suspicion of having sleep disorders. We used a questionnaire with sociodemographic questions and the Epworth sleepiness scale. Blood pressure, weight, height, and SpO2 were measured. Multiple linear regression was used in order to create a prediction model for sleep apnea, the apnea-hypopnea index (AHI) being the dependent variable. Multinomial logistic regression was used in order to identify factors independently associated with the severity of apnea (mild, moderate, or severe) in comparison with the absence of apnea. Results: The prevalence of sleep apnea in the study population was 71.2%. Sleep apnea was more prevalent in men than in women (81.2% vs. 56.8%; p < 0.001). The multiple linear regression model, using log AHI as the dependent variable, was composed of the following independent variables: neck circumference, witnessed apnea, age, BMI, and allergic rhinitis. The best-fit linear regression model explained 39% of the AHI variation. In the multinomial logistic regression, mild apnea was associated with BMI and neck circumference, whereas severe apnea was associated with age, BMI, neck circumference, and witnessed apnea. Conclusions: Although the use of clinical prediction models for sleep apnea does not replace polysomnography as a tool for its diagnosis, they can optimize the process of deciding when polysomnography is indicated and increase the chance of obtaining positive polysomnography findings.

Objective: Barriers to physical activity can affect the functional capacity and quality of life of patients with pulmonary hypertension (PH). This study aimed to identify the main barriers to physical activity in patients with PH and to examine whether those barriers are related to functional capacity, echocardiographic variables, or quality of life. Methods: This was a cross-sectional observational study involving 70 patients. Participants scored seven potential barriers to their activities, with a score = 5 indicating a significant barrier. Participants completed the Medical Outcomes Study 36-item Short-Form Health Survey (SF-36) and Manchester Respiratory Activity of Daily Living questionnaire, as well as the six-minute walk test. Correlation analysis, univariate analysis and multiple logistic regression were performed. Results: As a perceived barrier to physical activity, 'lack of will' or 'lack of energy' was cited by 67% of the patients. The 'lack of will' barrier was found to correlate with all SF-36 domains except bodily pain. We also identified a correlation between the SF-36 vitality domain and the barriers 'lack of energy', 'lack of will' and 'lack of structure'. The logistic regression analysis indicated that the vitality domain correlated significantly with the barriers 'social influence', 'lack of energy', 'lack of will', and 'lack of structure'. For each unit decrease in the vitality score, there was a 10% increase in the probability of citing the barrier 'lack of will'. No significant correlations were identified between any of the perceived barriers and echocardiographic parameters. Conclusions: The perceived barrier most commonly reported was 'lack of will/energy', which correlated with almost all SF-36 domains, especially vitality. The 'lack of will' barrier also correlated with functional capacity.

Objective: To assess the quality of life of patients with lung cancer and to compare it with that of individuals without cancer. Methods: The Medical Outcomes Study 36-item Short-Form Health Survey (SF-36) was administered to 57 patients diagnosed with lung cancer, treated at the Lung Cancer Outpatient Clinic of the Hospital São Paulo, and to a control group of 57 individuals recruited from the Extra Penha workout group. The Mann-Whitney test was used to compare the groups, domain by domain. The first model of logistic regression was adjusted for male gender, nonsurgical treatment, Karnofsky performance status and smoking, which were included as predictors. The second model was adjusted for each SF-36 domain in order to identify increases in the proportions of patients in stage IIIB or IV. Results: The lung cancer group and the control group presented the following mean scores, respectively, for the SF-36 domains: role limitations due to physical health problems, 29.39 ± 36.94 and 82.89 ± 28.80; role limitations due to emotional problems, 42.78 ± 44.78 and 86.55 ± 28.77; physical function, 56.49 ± 28.39 and 89.00 ± 13.80; vitality, 61.61 ± 23.82 and 79.12 ± 17.68; bodily pain, 62.72 ± 28.72 and 81.54 ± 19.07; general health, 62.51 ± 25.57 and 84.47 ± 13.47; emotional well-being, 68.28 ± 23.46 and 82.63 ± 17.44; and social functioning, 72.87 ± 29.20 and 91.67 ± 17.44. The logistic regression model showed that role limitations due to physical health problems, physical function and emotional well-being were predictors of stages IIIB and IV. Conclusions: The patients with lung cancer had a poorer quality of life, especially regarding physical aspects, than did the control subjects.

Objectives: To evaluate the incidence of venous thromboembolism (VTE) in hospitalized patients with COVID-19 who underwent diagnostic tests for suspected VTE, and to correlate the IMPROVE-DD score with the incidence of VTE in this cohort. Methods: This retrospective study included consecutive patients with COVID-19 and suspected VTE, admitted between March 2020 and September 2021 at a private hospital in Salvador (BA), Brazil, who underwent lower or upper limb venous Doppler ultrasound or chest angiotomography. Descriptive analyses and comparisons using the chi-square test were performed to identify factors potentially associated with the risk of VTE. Results: A total of 517 patients were included, with an in-hospital VTE incidence of 18.6% (96 events). Risk factors significantly associated with VTE included obesity, ICU admission, central venous catheter use, longer hospital stays, greater lung tomographic involvement/severity, the need for mechanical ventilation, D-dimer levels at least twice the upper limit of normal (2xULN), and the IMPROVE-DD score. The mean IMPROVE-DD score among patients with VTE was 4.7 (±3) versus 3.3 (±2.4) in those without VTE (p < 0.0001). D-dimer 2xULN was sensitive in identifying 94% of the 96 patients with VTE (p < 0.0001). The in-hospital mortality rate was 14.1%, with higher rates observed in patients with VTE (24%) compared to those without VTE (11.9%) (p = 0.003). Conclusions: The incidence of VTE in hospitalized COVID-19 patients was high and correlated with increased mortality. The IMPROVE-DD score effectively identified patients at risk for in-hospital VTE, suggesting it could help to identify a high-risk subgroup that may benefit from extended thromboprophylaxis.

Objective: To evaluate physical performance on the six-minute walk test (6MWT) in patients with non-cystic fibrosis bronchiectasis and to investigate its relationship with quality of life (QoL). To identify predictors of exercise performance, we also investigated whether six-minute walk distance (6MWD) is associated with clinical and spirometric findings. Methods: This was a cross-sectional study involving patients with non-cystic fibrosis bronchiectasis (age,  18 years), with at least one respiratory symptom for  2 years and an FEV1  70% of predicted. Patients underwent clinical evaluation, pulmonary function tests, the 6MWT, and QoL assessment with the Medical Outcomes Study 36-item Short-Form Health Survey (SF-36). Results: We included 70 patients (48 females). Mean age was 54.5 ± 17.7 years, and mean FEV1 was 44.9 ± 14.5% of predicted. The patients were divided into two groups: 6MWD-low (6MWD below the predicted lower limit; n = 23); and 6MWD-norm (normal 6MWD; n = 47). The following variables were significantly lower in the 6MWD-low group than in the 6MWD-norm group: age; age at diagnosis of bronchiectasis; proportion of former smokers; body mass index (BMI); FEV1% of predicted; and MEP% of predicted. There were no significant differences in the SF-36 scores between the groups. In the logistic regression model, lower age and lower BMI were significantly associated with lower 6MWD. Conclusions: In this sample, there was a high proportion of patients who had a lower than expected 6MWD. Although 6MWD was not related to QoL, it was associated with age and BMI.

Objective: The objective of this study was to evaluate the applicability of a modified version of the Saint George's Respiratory Questionnaire. The version evaluated elicits "agree" and "do not agree", rather than "yes" and "no", responses. The intention is to facilitate the comprehension of double-negative questions and to promote better recollection of symptoms by patients by shortening their symptom histories from 12 months to 3 months. Methods: A total of 30 clinically stable patients with chronic obstructive pulmonary disease were evaluated. The Saint George's Respiratory Questionnaire and the modified version of the same were administered 15 days apart. Results: All of the patients presented health-related alterations in their quality of life. Comparing mean scores between the two questionnaires, the greatest difference was seen in the Symptoms domain. No significant differences were found in any of the remaining domains or in the total scores. In a subsequent analysis, significant correlations between the two questionnaires were found in all domains: Symptoms (r = 0.71; p < 0.001); Activity (r = 0.75; p < 0.001); Impact (r = 0.73; p < 0.001) and Total (r = 0.86; p < 0.001). Conclusion: The modified version of the Saint George's Respiratory Questionnaire is as effective as the original in gauging quality of life. However, various symptoms recollection time frames should be investigated in order to determine which would be the best time frame to employ in the analysis.

Objectives: To verify the prevalence of tuberculosis (TB)/HIV co-infection and the ability of the clinical history to detect the HIV infection in TB inpatients. Setting: Eduardo de Menezes Hospital, reference for both TB and AIDS. Patients and methods: All patients admitted with TB in a pneumology ward were evaluated prospectively from 1/1/1997 to 1/31/1998. The clinical history was directed to the presence of risk factors for AIDS or TB, previous treatments or abandoned treatments for TB, and TB clinical forms. Patients with AIDS defining illnesses, except for TB, and with previous anti-HIV tests were excluded. All patients had an ELISA anti-HIV serology, and when positive, a Western-Blot test was performed to confirm the previous result. X-square test and Fisher test were used for statistical analysis. Results: Sixty-five patients were divided into group I (positive serology for HIV, n = 6) and group II (negative serology for HIV, n = 59). There were no statistical differences between the groups comparing the risk factors for AIDS and TB, previous treatments or abandoned treatments for TB, or TB clinical forms. Conclusions: The high prevalence of TB/HIV co-infection (9.2%) reinforces that: 1) the clinical history was not able to detect a significant number of patients with TB/HIV co-infection and that: 2) anti-HIV serology should be performed in all patients with active TB forms.

Introduction: Bronchoscopic is a diagnostic and therapeutic procedure performed by introducing a flexible tube in the airways that allows for the visualization even of the smallest airways. In order to prevent or reduce the risk of infection, the bronchoscope must be adequately disinfected with at least high level disinfection. Purpose: Check for the risk of bacterial contamination for patients submitted to bronchoscopy at the Hospital São Paulo of Unifesp University, State of São Paulo. Methods: From 1997 to 1998, bronchoscope reprocessing included cleaning, rinsing with sterile or potable water, followed by rinsing with 2% glutaraldehyde for 20 minutes, rinsing again with sterile or potable water, and rinsing with 70% ethyl alcohol, and forced-air drying through the suction channel. Samples of 65 patients were collected for microbiologic tests by instilling sterile saline solution through the suction channel of the bronchoscope. Results: After reprocessing, the following were found in the samples: Staphylococcus epidermidis, Enterobacter sp, Acinetobacter baumanni, Streptococcus viridans, Staphylococcus aureus, Streptococcus beta hemoliticus A, Staphylococcus coagulase negative, and mycobacterial growth was found in the culture of five samples. Conclusions: Bronchoscope disinfection with 2% glutaraldehyde was not sufficient to assured disinfection of the scope and the presence of Staphylococcus epidermidis shows that there was bronchoscope contamination due to handling after disinfection.

Background: There is currently no consensus regarding which factors influence the quality of life of patients suffering from chronic obstructive pulmonary disease (COPD). However, identifying such factors could orient approaches to improving the quality of the lives of these patients. Objective: To evaluate factors that can interfere with quality of life in COPD patients selected for pulmonary rehabilitation. Methods: Twenty-one patients with moderate to severe COPD were evaluated. Maximal inspiratory pressure (MIP), 6-minute walk test (6MWT), body mass index (BMI), pulmonary function, blood gases, grip strength (measured with a dynamometer), quadriceps strength and St. George's Respiratory Questionnaire (SGRQ) scores were assessed. Results: Statistically significant negative correlations with quality of life were found for the following factors: "impact" scores of: forced expiratory volume in one second (FEV1) (r = -0.68; p = 0.004), FEV1 to forced vital capacity ratio (FEV1/FVC) (r = -0.61; p = 0.014), peak expiratory flow (PEF) (r = -0.53 (p = 0.015), 6MWT (r = -0.63; p = 0.001) and BMI (r = -0.64; p = 0.002); "activity" scores for: MIP (r = -0.57; p = 0.007), baseline arterial oxygen saturation by pulse oximetry (SpO2) (r = -0.52; p = 0.018) and 6MWT (r = -0.58; p = 0.007); "symptom" score for: BMI (r = -0.60; p = 0.005); and "total" scores for: FEV1 (r = -0.64; p = 0.01), PEF (r = -0.47; p = 0.033) and BMI (r = -0.57; p = 0.009). Multiple linear regression revealed the primary factors influencing quality of life to be: BMI, which presented a significant influence on "symptom", "impact" and "total" scores (p = 0.002, p = 0.009 and p = 0.024, respectively); and 6MWT, which had a significant influence on "activity" and "impact" scores (p = 0.048 and p = 0.010, respectively). Conclusions: The BMI and 6MWT were shown to have an influence on quality of life in the COPD patients studied. Therefore, therapeutic approaches to improving the quality of life of COPD patients should take these indices into consideration.

Objective: Patients with lung cancer experience different feelings and reactions, based on their family, social, cultural, and religious backgrounds, which are a source of great distress, not only for the patients but also for their family caregivers. This study aimed to evaluate the impact that lung cancer stage and quality of life (QoL) of lung cancer patients have on caregiver burden. Methods: This was a prospective cross-sectional study. Consecutive patient-caregiver dyads were selected and asked to complete the Hospital Anxiety and Depression Scale and the Medical Outcomes Study 36-item Short-Form Health Survey (SF-36). Family caregivers also completed the Caregiver Burden Scale. Group-based modeling was used in order to identify patients with early- or advanced-stage cancer (IA to IIIA vs. IIIB to IV) plus non-impaired or impaired QoL (SF-36 total score > 50 vs. ≤ 50). Patient-caregiver dyads were stratified into four groups: early-stage cancer+non-impaired QoL; advanced-stage cancer+non-impaired QoL; early-stage cancer+impaired QoL; and advanced-stage cancer+impaired QoL. Results: We included 91 patient-caregiver dyads. The majority of the patients were male and heavy smokers. Family caregivers were younger and predominantly female. The burden, QoL, level of anxiety, and level of depression of caregivers were more affected by the QoL of the patients than by their lung cancer stage. The family caregivers of the patients with impaired QoL showed a higher median burden than did those of the patients with non-impaired QoL, regardless of disease stage. Conclusions: Caregiver burden is more affected by patient QoL than by lung cancer stage.

Background: Hyperhidrosis or excessive sudoresis is a chronic disease associated with important subjective distress. Objective: To propose a specific questionnaire to evaluate the quality of life of patients with hyperhidrosis. Methods: From October 1995 to March 2002, 378 patients (234 females), with a mean age of 26.8 years, were evaluated before and after video-assisted thoracic sympathectomy. Results: Therapeutic success was obtained in 90% of the procedures. The recurrence rate was 10% for palmar and 11% for axillary hyperhidrosis; 27% of the patients who had recurrence were re-operated successfully. No serious complications were reported. Of the total number of patients, 91% answered to the quality of life questionnaire, and 86% of them reported improvement after the procedure. Conclusions: Thoracic sympathectomy is a therapeutic method capable of changing the quality of life of patients with hyperhidrosis. The questionnaire applied has shown these changes.

Pectus excavatum (PEX) is the most frequent congenital deformity of the anterior chest wall and is defined as the dislocation of the medial or inferior portion of the sternal region toward the spinal column. There are various ways to measure the deformity. In this study, we present an objective method of assessing such deformity, the anthropometric index for PEX (AI-PEX). The AI-PEX was developed in the Thoracic Surgery Department of the Heart Institute - University of São Paulo School of Medicine Hospital das Clínicas. The anthropometric measurements are taken during the physical examination. We herein report two cases involving patients with PEX assessed using the AI-PEX and treated with the minimally invasive Nuss technique. The measurements were always taken at the point of greatest deformity. The patients were assessed on the day of the operation and again at 60 days after the surgery. The AI-PEX allowed us to obtain a satisfactory assessment of the defect. In both patients, the post-operative evolution was favorable.

Epidemiologic data on idiopathic pulmonary fibrosis are relatively scarce, and its real incidence and prevalence are unknown. Recent studies suggest that idiopathic pulmonary fibrosis mortality is rising in developed countries. Objectives: To describe idiopathic pulmonary fibrosis mortality in the State of Rio Grande do Sul (RS), Brazil, from 1970 to 2000, analyzing its trend and comparing it with that from other countries. Methods: Prevalence study, using data from the Brazilian Institute of Geography and Statistics (IBGE), analyzing death certificates in which idiopathic pulmonary fibrosis was stated as ultimate cause of death. Results: Annual mortality adjusted to population was 0.22/100,000 persons in the 1970's, 0.3/100,000 persons in the 1980's, and 0.48/100,000 persons in the 1990's. Total mortality rised 36% from 1970 to 1980, and 70% from 1980 to 1990. Mortality adjusted to population rised 36% and 60% during the same periods. The rise in both total and adjusted mortality from IPF was statistically significant (p < 0.05). The mean mortality rate per 100,000 persons during 1996 to 1998, however, was 0.683, corresponding to a rise of 70% when compared to the previous three-year period, which was 0.4 (p = 0.0002), probably reflecting encoding practices. Conclusion: There was a significant increase in IPF mortality in RS from 1970 to 2000, in part due to changes in coding practices. This increase is in conformity with observations in other countries, althought mortality rates in RS are considerably lower.

Background: Pulmonary hypertension secondary to chronic thromboembolism is a severe and debilitating disease and has been associated with high mortality. Pulmonary thromboendarterectomy is the treatment of choice. Objective: To evaluate the impact of pulmonary thromboendarterectomy on the quality of life of patients with pulmonary hypertension secondary to chronic thromboembolism using the SF-36 Health Survey. Method: The SF-36 Health Survey questionnaire was administered to 13 patients prior to and at least 3 months following thromboendarterectomy. Results: Of the 13 patients studied, 7 were female and 6 were male. Mean age was 45.7 ± 18.3. All were submitted to thromboendarterectomy. After surgery, all SF-36 domains, with the exception of the "mental health" domain, improved. Conclusion: Pulmonary thromboendarterectomy provides significant improvement in patient quality of life.

Background: Pulmonary rehabilitation is widely recommended for the treatment of chronic obstructive pulmonary disease. Objective: To evaluate the efficacy of pulmonary rehabilitation in improving exercise capacity, respiratory muscle strength and quality of life of chronic obstructive pulmonary disease patients. Method: This was an open, non-randomized clinical trial involving 27 clinically stable ex-smokers with chronic obstructive pulmonary disease who were enrolled in a pulmonary rehabilitation program. All were evaluated before and after pulmonary rehabilitation. Results: Mean age was 65 ± 5 years, mean body mass index was 25 ± 4 kg/m2, mean forced expiratory volume in one second was 55 ± 25% of predicted, mean ratio between forced expiratory volume in one second and forced vital capacity was 50 ± 12%, and mean arterial oxygen tension was 70 ± 7 mmHg. Comparison of pre- and post-pulmonary rehabilitation values revealed improvement in the distance walked in the 6-minute walk test (513 ± 99 m vs. 570 ± 104 m), maximum upper limb load (2 ± 1 kg vs. 3 ± 1 kg) and maximal inspiratory pressure (-89 ± 23 cmH2O vs. -102 ± 23 cmH2O), as well as in the activity domain, impact domain and total score on the Saint George's Respiratory Questionnaire. Conclusion: Pulmonary rehabilitation, when performed with care and with a focus on physical training, is efficacious in increasing not only the distance walked in the 6-minute walk test but maximum upper limb load, maximal inspiratory pressure and quality of life as well.

Objective: To investigate the impact of a pulmonary rehabilitation program on the functional capacity and on the quality of life of patients on waiting lists for lung transplantation. Methods: Patients on lung transplant waiting lists were referred to a pulmonary rehabilitation program consisting of 36 sessions. Before and after the program, participating patients were evaluated with the six-minute walk test and the Medical Outcomes Study 36-item Short-Form Health Survey (SF-36). The pulmonary rehabilitation program involved muscle strengthening exercises, aerobic training, clinical evaluation, psychiatric evaluation, nutritional counseling, social assistance, and educational lectures. Results: Of the 112 patients initially referred to the program, 58 completed it. The mean age of the participants was 46  14 years, and females accounted for 52%. Of those 58 patients, 37 (47%) had pulmonary fibrosis, 13 (22%) had pulmonary emphysema, and 18 (31%) had other types of advanced lung disease. The six-minute walk distance was significantly greater after the program than before (439 ± 114 m vs. 367 ± 136 m, p = 0.001), the mean increase being 72 m. There were significant point increases in the scores on the following SF-36 domains: physical functioning, up 22 (p = 0.001), role-physical, up 10 (p = 0.045); vitality, up 10 (p < 0.001); social functioning, up 15 (p = 0.001); and mental health, up 8 (p = 0.001). Conclusions: Pulmonary rehabilitation had a positive impact on exercise capacity and quality of life in patients on lung transplant waiting lists.
