Pulmonary rehabilitation (PR) is a comprehensive intervention of self-management education and exercise training that improves quality of life, exercise tolerance, symptoms of dyspnea, and reduces the risk of hospitalization in patients living with chronic respiratory diseases such as chronic obstructive pulmonary disease, asthma, lung cancer, and interstitial lung disease. Despite the proven benefit of pulmonary rehabilitation, recent studies have found notable inconsistencies in its organization and delivery. Inconsistencies within clinical practice are likely to affect the quality in the delivery of pulmonary rehabilitation. Quality indicators (QIs) are tools similar to a checklist that can potentially remediate these concerns. While other jurisdictions have created quality indicators for pulmonary rehabilitation programs, their methodological approach to developing these quality indicators is questionable. This study developed 56 quality indicators with a rigorous approach using a modified RAND Appropriateness Method. A panel comprising twelve PR healthcare professionals and stakeholders was created to create a list of QIs. The panel rated each indicator based on four criteria (importance, scientific soundness, reliability, and feasibility) and listed which indicator they believed could determine a quality pulmonary rehabilitation program. This study recommends that the 56 QIs, based upon consensus, be used for operationalizing the evaluation and auditing of PR programs as well as for establishing clinical benchmarks.

Previous researchers have identified that participation in a pulmonary rehabilitation program improves health outcomes yet, continuation in a weekly maintenance program yielded mixed results. Self-management programs have had reported use in chronic obstructive pulmonary disease (COPD). A meta analysis has identified that no self-management program had evaluated the effect of this type of intervention on the functional status of the participant with COPD. Reduced functional status is well reported as an indicator of disease progression in COPD. Adjuvant therapies for people with COPD need to demonstrate an effect in this domain. The Stanford model chronic disease self-management program (CDSMP) had been reported as a program that may optimise the health of people with chronic health conditions. However, its utility has not been formally evaluated for people with COPD. There have not been any reports of a comparison of the Stanford model CDSMP with pulmonary rehabilitation via a randomised controlled study in COPD. Aim: To compare and evaluate the health outcomes from participation in nurse ledwellness-promoting interventions conducted in the ambulatory care setting of a metropolitan hospital. Participants were randomised to either a six-week behavioural intervention: the Stanford model CDSMP or, a six-week pulmonary rehabilitation program and results compared to usual care (a historical control group). The efficacy of the interventions was measured at week seven and repeated at week 26 and 52. Following the week seven evaluation, the pulmonary rehabilitation program participants were rerandomised to usual care or, weekly maintenance pulmonary rehabilitation for 18 weeks and, followed up until the study completion at week 52.Little is reported about the costs of care for people with COPD in Australia. This study prospectively evaluated the costs of the interventions and health resource for the 52 weeks and undertook a cost utility analysis. Methods: Walking tests (The Incremental Shuttle Walking Test) and questionnaires asking participants about their health related quality of life, mood status, dyspnoea and self efficacy were assessed prior to randomisation to either six week intervention and repeated at weeks 7, 26 and 52. The implementation of these adjuvant therapies enabled all costs associated with the interventions to be prospectively examined and compared. Results: During the two years of recruitment 252 people (54% males) with a mean age 71 years (SD 11, range 39-93 years) were referred to the study. Student’s ttests identified that there were no statistically significant differences (P=0.16) between all those referred by age and gender as compared to all those admitted to Hospital A with an exacerbation of COPD. Ninety-seven people (51% male) with a mean age of 68 years (SD 9, range 39-87 years) agreed to participate in the study. Follow up in the study continued for 12 months following enrolment with only a modest level of attrition by week seven (3%) and week 52 (25%). Following the six-week interventions, both the pulmonary rehabilitation and CDSMP groups recorded statistically significant increases in functional capacity, self-efficacy and health related quality of life.Functional performance was additionally evaluated in the intervention arms with participants wearing pedometers for the six-week period of the interventions. There were no statistically significant differences between steps per week (P=0.15) and kilometres per week (P=0.17) walked between these two groups in functional performance. The Spearman rho statistic identified no statistically significant relationship between functional performance and the severity of COPD (rs (33) = 0.19, P = 0.26). No significant correlation between functional capacity and functional performance was identified (rs (32) = 0.19, P = 0.29). This suggests that other factors contribute to daily functional performance. The largest cost of care for people with COPD has been reported to be unplanned admissions due to an exacerbation of COPD.In this study there were no statistically significant differences between the three intervention groups in the prospective measurement of ambulatory care visits, Emergency Department presentations and admissions to hospital. The calculation of costs illuminated the costs of care in COPD are greater than the population norm. In addition, maintenance pulmonary rehabilitation generated a greater quality adjusted life year (QALY) than a six-week program. Despite the strength of the participants preferences (as measured by the QALY) for maintenance PRP, there were no significant differences in use of hospital resources throughout the study period by the three intervention groups, which suggests some degree of equivalence.

A Doença Pulmonar Obstrutiva Crônica (DPOC) é uma doença caracterizada pela limitação ao fluxo aéreo, não totalmente reversível. Dentre as terapêuticas indicadas, a reabilitação pulmonar é uma estratégia de tratamento multidisciplinar, que tem por objetivo melhorar a qualidade de vida do paciente, reintegrando-o à sociedade. Objetivos: Descrever o processo e os custos de implantação na forma de um projeto de extensão universitária, os motivos da evasão e os resultados obtidos com um programa de reabilitação pulmonar. Material e Métodos: Após formar um grupo multidisciplinar no Centro Universitário Feevale e estabelecer uma parceria com a Secretaria Municipal da Saúde de Novo Hamburgo, os pacientes portadores de DPOC são encaminhados ao programa de reabilitação pulmonar (PRP). São avaliados pelo médico pneumologista, fisioterapeuta, nutricionista, psicólogo e educador físico. Após estas avaliações são formados grupos de até 16 pacientes que permanecem por um período de 4 meses, com três sessões semanais de treinamento físico, orientações nutricionais, encontros educativos e grupos de apoio psicológico. Foram avaliados o perfil destes pacientes, os custos para a implantação, as causas de evasão após o início do programa, bem como os resultados obtidos após o período de tratamento, medidos através do teste de caminhada dos seis minutos, do trabalho de caminhada através do produto distância-peso corporal e do questionário Saint George de qualidade de vida. Para a análise dos resultados foi utilizada a estatística descritiva, para comparação das médias o Teste t de Student. Resultados: O PRP foi implantado na forma de um projeto de extensão universitária, com um custo total de R$ 64 224,60. Foram avaliados 134 pacientes encaminhados dos postos de saúde do município de Novo Hamburgo e dos municípios vizinhos. Do total, 38 (28,4%) pacientes foram excluídos e 7(5,2%) foram a óbito antes de completar a avaliação. Desses, 89 (66,5%) portadores de DPOC de moderado a grave foram incluídos no PRP. A média de idade dos pacientes foi de 63,5±9,9 anos, predominou o sexo masculino 62(69%), com índice de massa corporal (IMC) médio de 23,5±5,3 Kg/m2, com média de Volume expiratório forçado no primeiro segundo (VEF1) de 1,16L(42,8±23,4% do previsto). Dos incluídos no PRP, 40 (44,9%) abandonaram, principalmente por problemas sócio-econômicos e 49 (55,1%) concluíram a reabilitação. Os dados para análise antes e depois do PRP estavam disponíveis para 37 pacientes que formaramo grupo para analisar os resultados do PRP. No teste de caminhada dos seis minutos, ocorreu uma variação significativa de 34,12m na média distância (367,15±101,93m vs. 401,27±95,55m; p <0,001). Ocorreu melhora significativa de 2,65 Km.Kg-1 (24,36±9,62 Km.Kg-1 vs. 27,01±10,0 Km.Kg-1) no trabalho de caminhada medido pelo produto distância-peso e uma melhora significativa com redução de 11% (46 vs. 35; p<0,001) no total do questionário Saint George de qualidade de vida. Conclusões: O PRP pode ser implantado na forma de um projeto de extensão universitária, com custo relativamente baixo pela sua abrangência e benefícios. A condição social dos pacientes foi o maior determinante da evasão, mas os pacientes que concluíram o PRP apresentaram uma melhora significativa na sua capacidade de exercício e na qualidade de vida.
Chronic obstructive pulmonary disease (COPD) is characterized by partially reversible airway obstruction. Pulmonary rehabilitation is one of the therapeutic interventions indicated for the treatment of COPD, and consists of a multidisciplinary treatment strategy whose purpose is to improve quality of life and to reintegrate patients into society. Objective: To describe the process and cost of implementing a university extension program for pulmonary rehabilitation, as well as the causes of patient dropout and the results achieved. Material and methods: After a multidisciplinary group was formed at Centro Universitário Feevale and a partnership was established with the Municipal Department of Health of Novo Hamburgo, patients with COPD were referred to the pulmonary rehabilitation program (PRP). They were examined by a pulmonologist, a physical therapist, a nutritionist, a psychologist and a physical education specialist. After evaluations, groups of up to 16 patients were formed and had 3 weekly meetings for 4 months. During meetings, patients participated in physical exercise training, nutritional counseling, educational meetings and psychological support groups. We evaluated patient data, costs of program implementation and causes of patient dropout. Also, the results obtained after PRP were measured by the 6-minute walk test, work calculated as the product of distance x body weight, and the St George respiratory questionnaire to assess quality of life. Descriptive statistics was used to analyze results, and the Student t test, to compare means. Results: PRP was implemented as a university extension program at a total cost of R$ 64,224.60. One hundred thirty-four patients referred by health stations in Novo Hamburgo and neighboring cities were evaluated; 38 (28.4%) of these patients were excluded and 7 (5.2%) died before they completed the initial evaluation. The other 89 (66.5%) patients with moderate to severe COPD were included in PRP. Mean patient age was 63.5±9.9, 62 (69%) were men, mean body mass index (BMI) was 23.5±5.3 kg/m2, and mean forced expiratory volume in one second (FEV1) was 1.16 L (42.8±23.4% of predict value). Forty (44.9%) patients dropped out, most of them due to socioeconomic problems, and 49 (55.1%) completed the rehabilitation program. Data for the analysis before and after PRP were available for 37 patients, who formed the group for analysis of PRP results. The 6-minute walk test showed a significant increase of 34.12 m in distance(367.15±101.93 m vs. 401.27±95.55 m; p <0.001). A significant improvement of 2.65 km.kg-1 (24.36±9.62 km.kg-1 vs. 27.01±10.0 km.kg-1) was observed in distance x body weight product, and total scores of the St. George questionnaire showed a reduction of 11% (46 vs. 35; p<0.001), which indicated a significant improvement in quality of life. Conclusion: PRP was implemented as a university extension program at a relatively low cost when considering its extent and benefits. Social condition was the main cause of patient dropout, but those that completed PRP had a significant improvement in their capacity for physical exercise and in quality of life.

O aumento no número de células inflamatórias, a produção anormal de citocinas pró-inflamatórias e o desequilíbrio entre a formação de radicais livres e a capacidade antioxidante geram alterações locais e sistêmicas na doença pulmonar obstrutiva crônica (DPOC), associada com disfunção e perda da massa muscular. A reabilitação pulmonar é uma modalidade de tratamento com evidência A, cujos desfechos são medidos através da melhora da capacidade de exercício físico e qualidade de vida, mas estudos recentes demonstram uma redução no estresse oxidativo induzido pelo exercício, o que potencialmente também reduziria o dano tecidual. A análise do dano de DNA em linfócitos de sangue periférico foi utilizada como possível medida de desfecho em 13 de 39 portadores de DPOC submetidos a um programa de reabilitação pulmonar (PRP) com duração de 4 meses. Todos os pacientes foram submetidos ao teste da caminhada dos seis minutos (TC6) e ao questionário de qualidade de vida Saint George (QQVSG), sendo que 13 pacientes coletaram sangue antes e depois do PRP para análise do dano de DNA pela técnica de micronúcleos. Do total de 39 portadores de DPOC, 69,23% eram do sexo masculino com idades de 63,33 ± 8,60 anos e média de VEF1 de 1,06 ± 0,55L. Após o PRP, ocorreu aumento significativo na distância percorrida no TC6 (366,84±108,42 [pré PRP] vs. 400,76±94,55 [pós PRP], p=0,001) e melhora em todos os domínios do QQVSG (Sintomas: 47,05±21,28 [pré PRP] vs. 35,28±16,92 [pós PRP], p=0,005; Atividades: 62,84±27,07 [pré PRP] vs. 56,02±24,09 [pós PRP], p=0,038; Impacto: 33,30±18,71 [pré PRP] vs. 19,97±12,11 [pós PRP], p<0,001; Total: 49,41±21,99 [pré PRP] vs. 37,61±18,96 [pós PRP], p<0,001). Quanto à avaliação do dano genético, obteve-se uma diminuição estatisticamente significativa (p=0,014) na freqüência de micronúcleos (5,53±2,14 [pré PRP] vs. 3,07±2,13 [pós PRP] ), o que não ocorreu na análise das pontes nucleoplasmáticas e buds nucleares (1,15±0,89 [pré PRP] vs. 0,76±1,01 [pós PRP], p=0,244 e 1,69±1,43 [pré PRP] vs. 1,69±2,13 [pós PRP], p=0,804, respectivamente). A redução na freqüência de micronúcleos demonstrou que o PRP não somente melhorou a qualidade de vida e o desempenho na capacidade de exercício, mas também foi capaz de reduzir o dano de DNA.
Pulmonary rehabilitation is a treatment supported by level A evidence, and its outcomes are measured by the improvement in physical exercise capacity and quality of life. The objective of this study is to investigate if pulmonary rehabilitation reduces DNA damage in peripheral blood of patients with chronic obstructive pulmonary disease. DNA damage in peripheral blood lymphocytes was used as an outcome measure in 13 of 39 patients with chronic obstructive pulmonary disease who underwent a 4-month pulmonary rehabilitation program. All patients underwent the 6- minute walk test and answered the Saint George’s respiratory questionnaire to assess quality of life. Blood was collected from 13 patients before and after pulmonary rehabilitation program to analyze DNA damage using the micronucleus technique. After pulmonary rehabilitation program, there was a significant increase in 6- minute walk distance and improvement in all the Saint George’s respiratory questionnaire domains. The evaluation of genetic damage revealed a statistically significant decrease (p = 0.014) of micronucleus frequency. No significant differences were found in the analysis of nucleoplasmic bridges or nuclear buds. The decrease of micronucleus frequency demonstrated that PRP not only improved quality of life and performance in work capacity exercises, but also reduced DNA damage.

The study, using a quasi-experimental design, examined the relationship between participation in a comprehensive pulmonary rehabilitation program, locus of control, and the psychological and social concomitants of chronic obstructive pulmonary disease. The study investigated the following questions. To what degree participation in a comprehensive pulmonary rehabilitation program emphasizing a psychosocial component would: (1) generally produce a shift in persons from an external locus of control toward an internal locus of control, (2) specifically decrease the perception of chance, fate, or powerful others to influence and determine personal health; and (3) will result in the lessening of perceived negative effects of the psychological and social concomitants of chronic obstructive pulmonary disease. Two sample groups were evaluated in the study: (1) a group of 35 moderate to severe chronic obstructive pulmonary disease patients enrolled in a 96-hour comprehensive pulmonary rehabilitation program with a 32-hour psychosocial instructional component, and (2) a group of 35 moderate to severe chronic obstructive pulmonary disease patients receiving standard medical care at a Veterans Administration Hospital. Research instruments used for the study were the Multidimensional Health Locus of Control Scale and the Sickness Impact Profile. The research instruments were administered to each study group at approximately 16-week intervals. Results of the study indicated that participation in a comprehensive pulmonary rehabilitation program emphasizing a psychosocial component did not produce a significant shift in program participants from an external locus of control toward an internal locus of control, nor did it produce a significant decrease in the perception of chance, fate, or powerful others to influence and determine personal health. However, the study results indicated that participation in a comprehensive pulmonary rehabilitation program did produce a significant (P < .05) lessening of perceived negative physical and psychosocial effects of chronic obstructive pulmonary disease as measured by the physical scale, psychosocial scale, and total score of the Sickness Impact Profile.

A Doença Pulmonar Obstrutiva Crônica (DPOC) é uma doença sistêmica prevenível e tratável que se caracteriza pela diminuição do fluxo aéreo não totalmente reversível, levando a intolerância ao exercício, interferindo na execução das atividades de vida diária e reduzindo a qualidade de vida dos pacientes. A reabilitação pulmonar é uma forma multidisciplinar de tratamento que tem como objetivo melhorar a qualidade de vida, aumentar a tolerância ao exercício, reduzindo os sintomas de fadiga e dispnéia. Já está bem demonstrado através de estudos controlados e randomizados a eficácia do treinamento da resistência para membros inferiores, porém existem dúvidas se trabalhar força e resistência de maneira combinada pode modificar os resultados. Objetivo: Comparar os treinamentos para os membros inferiores, de força e resistência com o de resistência, em pacientes portadores de DPOC que realizaram um programa de reabilitação pulmonar. Pacientes e métodos: Após a avaliação médica para confirmação do diagnóstico da doença, 27 pacientes, que participaram de um programa de reabilitação pulmonar, foram randomizados para um de dois grupos: o Grupo 1 (G1) (n=13) realizou apenas o treinamento de resistência dos membros inferiores, enquanto os pacientes do Grupo 2 (G2) (n=14), treinaram resistência e força combinadas para membros inferiores. As variáveis analisadas antes e após o treinamento foram obtidas através dos seguintes testes: teste de caminhada de seis minutos, teste de carga máxima, trabalho de caminhada, questionário Saint George de qualidade de vida, percepção de esforço pela escala de Borg, e circunferência de coxa e perna. Resultados: No teste de caminhada houve aumento da distância percorrida após o programa intragrupos [G1(distância pré: 343,38±136,11m vs. distância pós: 396,81±96,46; p=0,048)], e [G2 (distância pré: 367,28±125,11 vs. distância pós: 392,84±118,16, p=0,160)]. Nos testes de carga máxima obteve-se os seguintes resultados: G1 (extensão de joelhos pré: 32±13kg vs. peso pós: 38±14kg; p=0,016); (flexão de joelhos pré: 5,85±2,0kg vs. pós: 7,7±3,1kg; p=0,007); (flexão plantar direito pré: 20,75±4,78 repetições vs. pós:21,58±7,22 repetições; p=0,73), (flexão plantar esquerda pré:21,67±5,48 repetições vs. pós:20,92±7,36 repetições; p=0,74) e G2 (peso em extensão de joelhos pré: 33,43±16kg vs. peso pós: 44±16,40kg; p=0,0001); (flexão de joelhos pré: 5,23±3,19kg vs. pós: 7,92±3,75kg; p=0,0001); (flexão plantar direito pré: 20,17±5,82 repetições vs. pós: 29,33±11,59 repetições; p=0,001); (flexão plantar esquerda pré: 20,45±6,34 repetições vs. pós: 30,91±10,48 repetições; p=0,0001). Não foram observadas diferenças estatisticamente significativas no trabalho de caminhada tanto intragrupos quanto entre os grupos G1 e G2. Observou-se uma melhora com relação à qualidade de vida representada pela redução total de 21,77 pontos percentuais no G1 e 22,54 pontos percentuais no G2, sem diferença estatisticamente significativa entre os grupos. A percepção de dispnéia através da escala de Borg não mostra redução significativa tanto intragrupos quanto entre os grupos [ G1 (Borg pré: 4,27±2,71 vs. pós: 2,88±1,98; p=0,091)] e [G2 (Borg pré: 4,86±3,30 vs. pós: 3,79±2,63; p=0,24)]. Quando comparados os resultados após o programa entre os grupos (G1 e G2), houve diferença estatística no teste de carga máxima apenas no movimento de flexão plantar direita e esquerda, sendo na esquerda significativamente maior (G1 Δ: -0,75 repetições vs. G2 Δ: 10,46 repetições, p=0,001), nas demais variáveis estudadas não houve diferença estatística significativa. Conclusão: Nesta população estudada os dois grupos melhoraram a qualidade de vida e a força nos movimentos de flexão e extensão dos joelhos. No entanto, o treinamento combinado de força e resistência não se mostrou superior ao treinamento isolado da resistência para membros inferiores.
“Chronic Obstructive Pulmonary Diseases” is a systemic, preventable and treatable disease characterized by the decrease of the aerial flow not totally reversible, leading to exercise intolerance, interfering in daily activities and reducing the patients’ quality of life. Pulmonary rehabilitation is a multidisciplinary approach of treatment that aims to improve the patients’ quality of life, increasing exercise tolerance, decreasing the symptoms of tiredness and breathing difficulties. Controlled and randomized studies have already proved the effectiveness of leg resistance training. However, there are still doubts as to whether concomitant strength and resistance efforts can change the results. Objective: To establish whether resistance and strength training is superior to leg resistance training, in a pulmonary rehabilitation program. Patients and methods: After the medical evaluation in order to confirm the diagnosis of the disease, 27 patients were randomly divided into two groups: group 1 patients (G1) (13) were submitted only to leg resistance while, group 2 patients (G2) (14) trained concomitant resistance and strength tests. The variations analyzed before and after the training were achieved through the following tests: 6-min walk test, maximum load test, work walking, Saint George quality of life questionnaire, effort perception by the Borg scale, and thigh and calf measurement. Results: In the walking test there was increase in the distance covered after the grouping program [G1 (pre-distance: 343,38±136,11m vs. post-distance: 396,81±96,46; p=0,048)], and [G2 (pre-distance: 367,28±125,11 vs. post-distance: 392,84±118,16, p=0,160)]. The following results were obtained in the maximum load test: (knee pre-stretching: 32±13kg vs. post7 weight: 38±14kg; p=0,016); (knee pre-bending: 5,85±2,0kg vs. post: 7,7±3,1kg; p=0,007); (right sole pre-bending: 20,75±4,78 repetitions vs. post:21,58±7,22 repetitions; p=0,73), (left sole pre-bending:21,67±5,48 repetition vs. post:20,92±7,36 repetitions; p=0,74) and G2 (knee pre-stretching: 33,43±16kg vs. post-weight: 44±16,40kg; p=0,0001); (knee pre-bending: 5,23±3,19kg vs. post: 7,92±3,75kg; p=0,0001); (right sole pre-bending: 20,17±5,82 repetitions vs. post: 29,33±11,59 repetitions; p=0,001); (left sole pre-bending: 20,45±6,34 repetitions vs. post: 30,91±10,48 repetitions; p=0,0001). No statistically significant differences were observed in the walking exercise in both groups. Although an improvement was observed in the quality of life represented by the total decrease of 21,77% in G1 and 22,54% in G2, it does not demonstrate any statistically significant difference between the two groups. The breathing difficulty perception through the Borg scale does not show significant reduction in both groups [G1 (pre-Borg: 4,27±2,71 vs. post: 2,88±1,98; p=0,091)] e [G2 (pre-Borg: 4,86±3,30 vs. post: 3,79±2,63; p=0,24)]. When the results between the groups (G1 and G2) were compared after the program, statistically significant difference in the maximum load test was observed only in the right and left sole bending movement, expressively greater in the left one. (G1 Δ: - 0,75 repetitions vs. G2 Δ: 10,46 repetitions, p=0,001). In the other variations studied, no statistically significant difference was observed. Conclusion: Both groups studied had an improved their quality of life and their strength in the stretching and bending knee movements after the pulmonary rehabilitation program. Nevertheless, concomitant strength and resistance training did not seem superior to the isolated leg resistance training.

To date, there is a scant amount of research on the long-term benefits of exercise training for individuals with moderate to severe chronic obstructive pulmonary disease. The purpose of this study was to evaluate standardized outcomes of a six-month maintenance pulmonary rehabilitation program to determine maintenance of functional capacity. Twenty-three subjects (sixteen men, seven women) diagnosed with clinical COPD ages 30-82 (65 + 12 years) participated in the retrospective study. The subjects were referred to an eight-week comprehensive pulmonary rehabilitation program after which upon twelve subjects continued onto a maintenance program. Eleven subjects chose not to participate in the maintenance program and were given a home exercise program and were encouraged to remain active. Hemodynamic, functional, and educational measures were taken prior to entry, upon completion of the hospital program, and again six-months post-program. Outcome tests were standardized using the Indiana Society of Cardiovascular and Pulmonary Rehabilitation Outcomes Manual. Significant differences were found between the maintenance and non-maintenance groups for systolic blood pressure in resting, exercise, and recovery measures at six monthsreevaluation. Differences in oxygen saturation were also found to reach significance between the two groups during recovery from the six-minute walk test. Interestingly, duration of exercise was found to be statistically significant between the two groups as well as emergency room visits and physician visits within the last six months. The maintenance group tended to have fewer emergency room and physician visits in addition to having self-reported higher durations of exercise. In conclusion, maintenance pulmonary rehabilitation programs have been shown to maintain physical activity levels for COPD patients and as a result, fewer quality of life consequences specifically the number of hospital admissions and emergency room visits.

The purpose of this study is to determine whether a community based rehabilitation exercise programme had an effect on pulmonary function, exercise tolerance and Health Related Quality of Life (HRQoL) in patients diagnosed with Pulmonary Tuberculosis (PTB). The prevalence of PTB in South Africa is one of the highest in the African continent. Assessing the effectiveness of the programme could provide further methods in improving compliance to pharmaceutical medication as well as an improvement in the morbidity experienced after diagnosis of PTB.

Introduction: Patients with COPD are characterised by symptoms of dyspnoea, limited exercise tolerance and low levels of physical activity which can lead to reduced quality of life. Pulmonary rehabilitation (PR) is recommended, however, not all are able to participate and there is a large dropout rate from this service. Home-based programmes aiming to enhance self-management skills can potentially provide an alternative model of delivery, allowing increased options for treatment. As one of the key components of PR is to enhance exercise endurance and physical activity, valid and reliable measures are needed to determine programme effectiveness. Therefore, the first aim of this thesis is to determine the validity, reproducibility and sensitivity of the SenseWear Pro 2 Armband, activity monitor (SWM) to be used in the main trial. The primary aim of this thesis is to describe the noninferiority randomised control trial of the effectiveness of the home based Self-management Programme of Activity Coping and Education (SPACE for COPD) in comparison to PR in patients with COPD. Methods: Validation of methods; One subject (EH) completed a battery of repeated walking tests using the speeds from the endurance shuttle walk test. Minute by minute energy expenditure (EE) and step counts were recorded from 9 SWM and indirect calorimetry was used as the criterion measure to determine the validity of EE output from the monitor.

Introdução: A fibrose pulmonar idiopática (FPI) é uma grave doença pulmonar crônica com sintomas de dispneia progressiva, resultando na diminuição da capacidade de exercício, impactando negativamente na qualidade de vida relacionada à saúde (QVRS). A reabilitação pulmonar (RP) melhora a capacidade funcional (CF) com redução dos sintomas, porém na FPI avançada seus efeitos e magnitudes são pouco conhecidos. Objetivo: Avaliar o impacto da RP sobre a QVRS e a CF em pacientes portadores de FPI. Métodos: Estudo de coorte retrospectiva em que foram revisados dados de 56 prontuários de pacientes em lista de transplante de pulmão com diagnóstico de FPI de acordo com o consenso da American Toracic Society 2011, submetidos a 12 semanas (36 sessões) de RP ambulatorial entre o período de janeiro de 2008 a outubro de 2012. Foram avaliadas a CF e a QVRS através do teste de caminhada de seis minutos (TC6) e do questionário 36-item short-form survey, SF36, respectivamente, antes e imediatamente após a RP. Resultados: Vinte e sete pacientes foram incluídos no estudo, 16 (61%) gênero masculino com idade média de 53 ±13 anos. Dezoito pacientes (68%) tinham diagnóstico histológico por biópsia pulmonar com padrão de pneumonia intersticial usual (PIU), com tempo médio de diagnóstico de 3 ±1,7 anos. Quanto à classificação da dispneia pela escala modified Medical Research Council (mMRC) basal, 59% dos pacientes foram classificados entre 3-4. Houve aumento significativo na distância percorrida de 393 ±88 metros para 453 ±90 metros (p<0,001). As medianas de dispneia sofreram diminuição significativa (p=0,01) na escala do mMRC de 2 (IC95%: 1-4) para 1 (IC95%: 1-4) e de 5 (Mín/Máx:1-10) para 3 (Mín/Máx:0-10) no BORG de dispneia no final do TC6. Apesar de caminharem maiores distâncias, a fadiga em membros inferiores foi menor com uma mediana de 2 (Mín/Máx:0-10) para 1 (Mín/Máx:0-9) (p=0,02). Houve aumento em 5 dos 8 domínios, porém somente a capacidade funcional foi significativa de 26 (IC95%: 19-33) para 37 (IC95%: 27-48) (p<0,05); os demais domínios não tiveram significância estatística. Conclusão: Observaram-se nestes pacientes aumentos da CF, com diminuição dos sintomas dispneia e fadiga; o que não se refletiu em melhora clínica na QVRS em portadores de FPI em lista de transplante de pulmão após um programa de RP.
Introduction: Idiopathic pulmonary fibrosis (IPF) is a chronic lung disease with severe symptoms of progressive dyspnea, resulting in decreased exercise capacity, negatively impacting the health-related quality of life (HRQL). Pulmonary rehabilitation (PR) improves functional capacity (FC) with reduction in symptoms, but in advanced IPF, its effects and magnitudes are unknown. Objective: To evaluate the impact of PR and in HRQL and in FC of patients with IPF. Methods: Coorte study with a retrospective review of data from 56 medical records of patients on lung transplant list diagnosed with IPF according to the American Toracic Society 2011 consensus, submitted to 12 weeks (36 sessions) of outpatient RP between January 2008 and October 2012. The FC and the HRQL were assessed through a six-minute walk test (6MWT) and the 36-item short-form survey (SF36) respectively before and immediately after PR. Results: Twenty-seven patients were included in the study, 16 (61%) male with a mean age of 53 ± 13 years. Eighteen patients (68%) had histologic diagnosis by lung biopsy compatible with usual interstitial pneumonia (UIP), with median time from diagnosis of 3 ± 1.7 years. Regarding the classification of the dyspnea in the modified Medical Research Council (mMRC) scale, 59% of patients were classified between 3-4. There was a significant increase in the distance covered from 393 ± 88 meters to 453 ± 90 meters (p <0.001). The baseline medians of dyspnea had a significant decrease (p = 0.01) in the mMRC scale from 2 (CI 95%: 1-4) to 1 (CI 95%: 1-4) and the median decreased from 5 (Min/Max: 1-10) to 3 (Min/Max :0-10) in the Borg dyspnea index at the end of the 6MWT. Although the patients walked greater distances, they had less fatigue in the legs, with a median decrease from 2 (Min/Max: 0-10) to 1 (Min/Max: 0-9) (p = 0.02). There was an increase in 5 of the 8 domains, but only the functional capacity was significant: from 26 (CI95%: 19-33) to 37 (CI95%: 27-48) (p <0.05), while the remaining areas were not statistically significant. Conclusion: We observed increases of FC in these patients, with decreased symptoms of dyspnea and fatigue; which were not reflected in clinical improvement in HRQL of patients with IPF on lung transplant list after a PR program.

The aim of this thesis was to modify and evaluate effects, as well as todescribe experiences of a nurse-led multidisciplinary programme of pulmonaryrehabilitation in primary health care for patients with chronicobstructive pulmonary disease (COPD) and their next of kin.Interviews were performed with 12 COPD nurses about their experiencesof patient education (I). Forty-nine patients participated in the interventiongroup and 54 in the control group in a quasi-experimentalstudy which investigated the effects of the programme on functional capacity,quality of life and exacerbation frequency during one year (II).Interviews were performed related to the experiences of 20 patients whohad participated in the six-week programme (III) and the experiences of20 next of kin to the patients that had participated (IV).The results showed that COPD nurses fluctuated between security andinsecurity in patient education and were in need of support, time, structureand collaboration to develop their patient education (I). In Study IIthere were no differences between the groups with regard to functionalcapacity and quality of life, but the number of exacerbations decreased inthe intervention group and increased in the control group (II). The patientsin study III had allowed themselves to live at their own pace followingthe programme but a constant fear was present in spite of the programme(III). Next of kin in Study IV had a life that remained overshadowedby illness but there were positive outcomes of the programme aslong as two years afterwards. The next of kin also had constant fear,however (IV).In conclusion, the six week programme brought about results in changingeveryday life. Nevertheless, all lived in the shadow of fear and uncertaintyin spite of the programme. More research is needed to address therequirements of COPD nurses, patients and next of kin.

Introduction: The participation profile of patients with chronic obstructive pulmonary disease (COPD) in pulmonary rehabilitation (PR) and the effectiveness of a video-based home exercise programme (VBHEP) were investigated using various research methods. Methods: The content analysis of the Move-On-Up exercise video against NICE guidelines and published research was performed. The video was evaluated for its suitability for use in VBHEP through focus groups involving UK population of patients with COPD and respiratory clinicians. Using the data from the content analysis and the focus groups, questionnaire items were synthesised for a national survey of both patients and clinicians. A study examined the relationship between participation in outpatient PR and patient measures of depression (Brief Assessment Depression Card), social support (Duke Social Support Index), multidimensional health locus of control (MHLC) and COPD severity (Medical Research Council dyspnea score). A randomised control trial (RCT) evaluated the effect of combining VBHEP and conventional outpatient PR on walking ability and PR benefit maintenance. The intervention arm received VBHEP concurrently with outpatient PR, while the control arm received only outpatient PR. Outcome measures included: the endurance shuttle walk test (ESWT), quality of life (QoL) (St George's Respiratory Questionnaire- SGRQ), MHLC and a modified Follick's activity diary. Measures were taken before PR, at the fourth and eighth weeks of PR and at six months post-PR. Focus groups were conducted between six and 20 months post-PR to evaluate patients' experience of and adherence to the use of VBHEP. Results: Critical review of 46 RCTs aided evaluation of the video demonstrating that the video content was consistent with both NICE recommendations and published research. The six focus groups that were part of the initial evaluation of the video involved 14 patients and 14 clinicians. The national survey generated responses from 60 patients and 62 clinicians; between 79 and 100% of respondents in each domain of the questionnaire indicated that the video is suitable for use. Fifty-one patients completed the study investigating the profile of patients participating in PR. The results indicated that depression has a moderate and negative statistically significant association with the uptake of PR (p < 0.05). Fifty-seven patients participated in the RCT [mean age 66.51 years (SD 9.96), mean FEV1% predicted 54.51% (SD 10.47)]. The results indicated that the use of VBHEP with outpatient PR has no significant additive effect in improving or maintaining the benefits of walking ability following PR (p<0.05). Seven patients participated in the follow-up focus groups where findings suggested that patients were still participating in VBHEP up to 20 months after it was first prescribed, though the frequency of its use appeared to diminish after PR ended. Conclusion: The Move-On-Up exercise video is suitable for VBHEP in patients with COPD. Patients with COPD and depression are less likely to take up a referral to PR compared to those without depression. The use of VBHEP concurrently with PR has no additive effect in improving or maintaining benefits of walking ability following PR. Adverse social circumstances and disease severity reduce the duration of participation in VBHEP.

Pulmonary Rehabilitation, especially due to aerobic exercise, positive impact in reducing morbidity/mortality of patients with COPD, however the economic impact with costs of implementing simple programs of aerobic exercise are scarce. This is a blind randomized clinical trials, which aimed to evaluate the costs and benefits of a simple program of aerobic exercise in individuals with COPD, considering the financial costs of the Public Health System and its secondary endpoints. We evaluated lung function, the distance walked during six minutes of walking, the respiratory and peripheral muscle strength, quality of life related to health (QLRH), body composition and level of activity of daily living (ADL) before and after eight weeks of an aerobic exercise program consisting of educational guidance for both groups, control and intervention and supervised walks to the intervention group. The health costs generated in both groups were calculated following table Brazilian Public Health System. The sample consisted of forty patients, two being excluded in the initial phase of desaturation during the walk test six minutes. Were randomized into control and intervention group thirty-eight patients, three were excluded from the control group and one was excluded from the intervention group. At the end, thirty-four COPD comprised the sample, 16 in the control group and 18 in the intervention group (FEV1: 50.9 ? 14% pred and FEV1: 56 ? 0.5% pred, respectively). After for intervention, the intervention group showed improvement in meters walked, the sensation of dyspnea and fatigue at work, BODE index (p <0.01) in QLRH, ADL level (p <0.001) as well as increased strength lower limbs (p <0.05). The final cost of the program for the intervention group was R $ 148.75, including: assessments, hiking supervised by a physiotherapist and reassessments. No patient had exacerbation of IG, while 2 patients in the CG exacerbated, generating an average individual cost of R $ 689.15. The aerobic exercises in the form of walking showed significant clinical benefits and economic feasibility of its implementation, due to low cost and easy accessibility for patients, allowing them to add their daily practice of aerobic exercises
A Reabilita??o Pulmonar, especialmente devido aos exerc?cios aer?bios, impacta positivamente na redu??o da morbidade/mortalidade do paciente com DPOC, entretanto o impacto econ?mico com custos de da implementa??o de programas simples de exerc?cios aerobios s?o escassos. Trata-se de um ensaio cl?nico aleat?rio controlado cego, que objetivou avaliar os custos e os benef?cios de um programa simples de exerc?cios aer?bios em indiv?duos com DPOC, considerando os custos financeiros do Sistema P?blico de Sa?de e seus desfechos secund?rios. Foram avaliadas a fun??o pulmonar, a dist?ncia percorrida no teste da caminhada dos 6 minutos, a for?a muscular respirat?ria e perif?rica, a qualidade de vida relacionada ? sa?de (QVRS), a composi??o corporal e o n?vel de atividade de vida di?ria (AVD) antes e ap?s oito semanas de um programa de exerc?cios aer?bicos composto por de orienta??es educacionais para ambos os grupos, controle e interven??o e caminhadas supervisionadas para o grupo interven??o. Os custos sanit?rios gerados em ambos os grupos foram calculados seguindo tabela do Sistema de Sa?de P?blico Brasileiro. A amostra foi composta por quarenta pacientes, sendo dois exclu?dos na fase inicial por dessatura??o durante o teste de caminhada de seis minutos. Foram aleatorizados em grupo controle e grupo interven??o trinta e oito pacientes, sendo que tr?s foram exclu?dos do grupo controle e um foi exclu?do do grupo interven??o. Ao final, trinta e quatro DPOC compuseram a amostra, 16 no grupo controle e 18 no grupo interven??o (VEF1: 50.9 ? 14 %pred e VEF1: 56 ? 0.5 %pred, respectivamente). Ap?s para interven??o, o grupo interven??o apresentou melhora nos metros caminhados, na sensa??o de dispneia e fadiga, no trabalho realizado, ?ndice de BODE (p<0.01), na QVRS, no n?vel de AVD (p<0.001) al?m de incremento da for?a dos membros inferiores (p<0.05). O custo final do programa para o grupo interven??o foi de R$ 148.75, incluindo: avalia??es, caminhadas supervisionadas por um fisioterapeuta e as reavalia??es. Nenhum paciente do GI apresentou exacerba??o, enquanto no GC 2 pacientes exacerbaram, gerando um custo individual m?dio de R$ 689.15. Os exerc?cios aer?bios na modalidade de caminhadas demonstraram significantes benef?cios cl?nicos e a viabilidade econ?mica de sua implementa??o, devido ao baixo custo e de f?cil acessibilidade para os pacientes, permitindo que estes possam adicionar as suas atividades di?rias a pr?tica de exerc?cios aer?bios

Objetivos: analisar os efeitos, após um período de 24 meses, de um Programa de Reabilitação Pulmonar sobre os níveis de ansiedade, depressão, qualidade de vida e desempenho no teste de caminhada em 30 pacientes com DPOC (idade: 60,8±10 anos; 70% do sexo masculino). Pacientes e Métodos: os participantes do estudo realizaram um Programa de Reabilitação Pulmonar com 12 semanas de duração, incluindo 24 sessões de exercício físico, 24 sessões de fisioterapia, 12 sessões de psicoterapia e 3 sessões educacionais. Todos os pacientes foram avaliados na linha de base (pré-teste) e ao término (pós-teste) do PRP através de quatro instrumentos: Inventário de Ansiedade de Beck, Inventário de Depressão de Beck , Questionário Respiratório de Saint George e Teste da Caminhada de 6 minutos. Vinte e quatro meses após a conclusão do PRP os pacientes foram reavaliados com os mesmos instrumentos de medida (teste atual). Resultados: Os pacientes demonstraram na comparação entre pré e pósteste, redução significativa dos níveis de ansiedade (pré: 10,7±6,3; pós: 5,5±4,4; p=0,0005), depressão (pré:11,7±6,8; pós:6±5,8; p=0,001) e melhora no índice de qualidade de vida (pré: 51±15,9; pós: 34,7±15,1; p=0,0001). No teste de caminhada houve um aumento significativo (pré: 428,6±75; pós: 474,9±86,3; p=0,03). Na comparação do pós-teste com o teste atual, os índices não demonstraram diferença estatística em nenhum dos critérios avaliados. Ansiedade (pós: 5,5±4,4; atual: 7,3±4,8; p=0,127), depressão (pós: 6±5,8; atual:7,8±5,7; p= 0,228), qualidade de vida ( pós: 34,7±15,1; atual: 40±13,3; p=0,157) e teste de caminhada (pós: 474,9±86,3; atual: 451±74,2; p=0,254) Conclusões: os benefícios obtidos pelos pacientes com a reabilitação pulmonar sobre os índices de ansiedade, depressão, qualidade de vida e teste de caminhada, persistiram ao longo dos 24 meses.
Study Objectives: to verify the long-term outcome of a pulmonary rehabilitation program on the levels of anxiety, depression and quality of life, as well, the six-minute walking test performance of 30 COPD patients (mean±SD, 60.8±10 years; 70% male). Design: the participants under went a 12-week treatment program: 24 session of physical exercises, 24 sessions of physiotherapy, 12 psychological sessions and three educational sessions. All patients were evaluated at baseline (pretest), at completion of the rehabilitation program (post-test), and two years later (current test) through four instruments: Beck Anxiety Inventory, Beck Depression Inventory, The St. George’s Respiratory Questionnaire and the Six- Minute Walk Test. Results: the comparison between pre and post-test demonstrated significant statistical improvements, including reduced anxiety (pre: 10.7±6.3; post: 5.5±4.4; p=0.0005) and depression (pre: 11.7±6.8; post: 6±5.8; p=0.001), increase endurance (pre: 428.6±75; post: 474.9±86.3; p=0.03), and better quality of life (pre: 51±15.9; post: 34.7±15.1; p=0.0001). There were no statistic differences when the results of the post-test were analyzed against the data of the current test. Anxiety (post: 5.5±4.4; current: 7.3±4.8; p=0.127), depression (post: 6±5.8; current: 7.8±5.7; p=0.228), endurance (post: 474.9±86.3; current: 451±74.2; p= 0.254) and quality of life (post: 34.7±15.1; current: 40±13.3; p=0.157). Conclusions: COPD patients are able to maintain the psychological and physical improvements acquired during a pulmonary rehabilitation program for two years.

Chronic obstructive pulmonary disease (COPD) is one of the main causes of morbidity and mortality worldwide with a substantial and increasing societal burden especially on underdeveloped countries. The present current study aimed at assessing the clinical and economic benefits of a pulmonary rehabilitation (PR) program with emphasis on physical exercise in COPD patients. Thirty patients with stable moderate to severe COPD were randomly assigned to two groups. The experimental group (EG) (mean age 69,53 ± 9,12, FEV1 % 36,1 ± 11,4) took part in a 8-week exercise program (3 times a week) and the control group (CG) (mean age 68,53 ± 9,43, FEV1 % 40,13 ± 14,33) was instructed to practice home physical activity without supervision. Changes in physiological measurements of six-minute walk test (6MWT) and pulmonary function, as well as changes in clinical variables as the BODE prognosis index, the St. George s Respiratory Questionnaire (SGRQ) and dyspnea using de BORG scale were examined. Admission rate due to disease exacerbations was measured over 4 months following PR initiation to calculate the direct health costs of COPD and the admission rate between EG and CG groups. Data analysis showed an improvement in physiological and clinical variables after PR in the EG. There was an increase in 6MWT walking distance (310±115 vs 403±63 m, p<0.01), in decrease SGRQ total score (54±14 vs 41±18, p=0,005) and in the BODE index (6,7±2,2 vs 3,7±2, p<0,01 ). Conversely, in the CG, there was a decrease in 6MWT walking distance (364±118 vs 332±141, p=0,02) after the following time. The EG showed a lower BODE prognosis index after the PR program than the CG (3,7±2 vs 5,5±2,5, p=0,03). The admission rate was higher for the CG than for the EG (6 vs 2). The mean for direct health costs in the CG was higher than the mean for the EG (R$ 2.439,5 ± 3.092,7 vs R$ 1.389,20 ± 2.146 p = 0,2891 ).Total costs for the CG were also significantly higher than the total costs for the EG (R$ 20.837,70 vs 36.593,10; p<0,01). PR reduced hospital admission with a 67,5% relative risk reduction (RRR) and a 27% absolute risk reduction (ARR), and a 3,7 number needed to treat (NNT) in 4 months following time. No adverse effects due to intervention were reported. In sum, the findings suggest clinical benefits with lower costs and a decrease on the number of hospital admissions after a PR program with emphasis on physical exercise in COPD patients.
A doença pulmonar obstrutiva crônica (DPOC) é uma das principais causas de morbidade e mortalidade no mundo com um crescente e substancial encargo social principalmente sobre os países em desenvolvimento. O presente estudo objetivou avaliar os benefícios clínicos e econômicos de um programa de reabilitação pulmonar (RP) com ênfase no exercício físico em pacientes com DPOC. Trinta pacientes com DPOC estável moderada a grave foram randomizados em dois grupos. O grupo experimental (GE) (media idade 69,53 ± 9,12, VEF1 % 36,1 ± 11,4) participou de um programa de exercícios com duração de 8 semanas (3 vezes por semana) e o grupo controle (GC) (média idade 68,53 ± 9,43, VEF1 % 40,13 ± 14,33) foi orientado a realizar atividade física em domicílio sem supervisão. Foram avaliados as alterações nas variáveis fisiológicas como a distância percdorrida no teste de caminhada de 6 minutos (TC6m) e função pulmonar, assim como as alterações nas variáveis clínicas como o índice prognóstico de BODE e o questionário de qualidade de vida St. George s Respiratory Questionnaire (SGRQ). As internações hospitalares em decorrência das exacerbações da doença foram aferidas no período de 4 meses após o início do programa de RP a fim de calcular o custo sanitário direto da doença e a taxa de internação entre os grupos. A análise de dados mostrou uma melhora significativa em variáveis clínicas e fisiológicas após a RP no GE. Houve um aumento na distancia percorrida no TC6m (310±115 vs 403±63 m, p<0.01), diminuição no índice de BODE (6,7±2,2 vs 3,7±2, p<0,01 ) e nos escores do questionário de qualidade de vida St. George s Respiratory Questionnaire ((54±14 vs 41±18, p=0,005). No GC, houve uma redução na distância caminhada no TC6m (364±118 vs 332±141, p=0,02) após o período de seguimento. O GE mostrou um menor índice prognóstico de BODE após o programa de RP quando comparado com o GC (3,7±2 vs 5,5±2,5, p=0,03). Houve uma maior taxa de internação no GC em comparação ao GE (6 vs 2). A média de custo do GC foi maior em relação ao GE (R$ 2.439,5 ± 3.092,7 vs R$ 1.389,20 ± 2.146 ; p = 0,2891) O custo total no GC também foi significativamente maior em relação ao GE (R$ 20.837,70 vs 36.593,10 ; p<0,01). A RP reduziu a admissão hospitalar com uma redução relativa de risco (RRR) de 67,5% e uma redução absoluta de risco (RRA) de 27% e um número necessário para tratar 3,7 (number need to treat - NNT) nos 4 meses de seguimento. Não houve relato de efeito adverso da intervenção. Em resumo, os resultados sugerem benefícios clínicos com menores custos e diminuição do número de admissões hospitalares após um programa de RP com ênfase no exercício físico em pacientes com DPOC.

Introdução: A fibrose cística também conhecida como mucoviscidose, é uma doença genética autossômica recessiva, crônica, com manifestações sistêmicas, sendo o transplante pulmonar uma das alternativas para o tratamento quando a doença se apresenta em fase terminal. Objetivos: Avaliar a função pulmonar, condicionamento físico e qualidade de vida em pacientes com fibrose cística após trinta meses do transplante pulmonar seguido de um programa de reabilitação do cardiopulmonar. Metodologia: Estudo de coorte ambispectivo, foram estudados 8 pacientes com fibrose cística (5 mulheres 3 homens com média de idade 27 ± 4,62 anos) no período de dezembro de 2006 a dezembro de 2010. Havido perda de 2 pacientes ao longo do estudo. Foram analisados o teste de caminhada de seis minutos(TC6M), testes de função pulmonar e o questionário SF-36 no pré-transplante, pós-transplante imediato, pósreabilitação cardiopulmonar e após trinta meses após o transplante. Resultados: Tempo de lista de espera de 883 ± 571 dias tempo de internação total 30,14 ± 12,6 dias. Os pacientes apresentaram em média no pré-transplante VEF1 25,1% e CVF 38,4%, no pós transplante imediato VEF1 52,6% e CVF 54,6%. após reabilitação VEF1 60,8% e CVF 65,2% e 30 meses pós transplante VEF1 66,6% e CVF 67,2% . No TC6M a média de distância percorrida antes do transplante foi de 488 metros, pós-transplante imediato 510 metros, pós-reabilitação 603 metros e 30 meses pós-transplante 462 metros. Quanto à qualidade de vida os pacientes apresentaram melhora nos momentos pós-alta hospitalar e após reabilitação e piora em alguns domínios 30 meses após o transplante. Conclusão: O transplante de pulmão permanece sendo um procedimento de alto risco, no entanto, é uma estratégia terapêutica viável para pacientes com fibrose cística em estágio avançado da doença. Os dados encontrados no estudo sugerem uma tendência positiva a curto prazo na capacidade funcional e qualidade de vida, contudo a médio prazo perecem diminuir, enquanto a função pulmonar apresenta crescente melhora a curto e médio prazo. São necessários mais estudos com um maior número de pacientes para se afirmar com propriedade os benefícios a longo prazo do transplante de pulmão para essa população.
Introduction: Cystic Fibrosis, also known as mucoviscidosis, is a chronic autosomal recessive genetic disorder with systemic manifestations, lung transplantation being one of the alternatives for treatment when the disease is in its terminal phase. Objective: Evaluate the lung function, physical conditions and the quality of life of the cystic fibrosis patient after 30 months from the lung transplantation following a rehabilitation program of cardiopulmonary therapy. Methodology: The study of the ambispective cohort, involved eight patients with cystic fibrosis (5 women and 3 men aged 27 ± 4.6 years) for the period from December 2006 to December 2010, two patients died during the study. Analysis was made of the Six Minutes Walk Test (6MWT), lung function and the SF-36 questionnaire for the pre-transplant, immediately post- transplant, post cardiopulmonary rehabilitation and 30 months after the transplant. Results: The waiting list was 883±571 days, hospitalization time totalled 30.14 ±12.6 days. The patients showed, on average, a pretransplant VEF1 25.1% and CVF 38.4%, immediately posttransplant VEF1 66.6% and CVF 54.6%, post cardiopulmonary rehabilitation VEF1 60.8% and CVF 65.2% end 30 months post-transplant VEF1 66.6% and CVF 67.2%. In the TC6M, the average distance done before the transplant was 488 meters, immediately post-transplant it was 510 meters, post cardiopulmonary rehabilitation it was 603 meters and 30 months after transplant it was 462 meters. The quality of life of the patients showed improvement from the moment of leaving the hospital and after rehabilitation but did deteriorate in some domains after 30 months from the transplant. Conclusion: The lung transplantation continues to be a high risk procedure, however it still is a therapeutic strategy available to patients with cystic fibrosis at the advance stage of the disease. The findings of the study suggest there is a positive trend in the short term functional capacity and quality of life in the medium term however perish decrease, while increasing lung function has improved in the short and medium term. Although it would require further study with a higher number of patients to affirm with confidence the benefit for the long term of lung transplants for this population.

Introduction: Currently, chronic obstructive pulmonary disease (COPD) is considered an important cause of morbidity and mortality, and the twelfth most prevalent disease in the world, thus representing a serious public health problem. It is common for patients with COPD to have poor sleep quality. As causes of this poor quality of sleep we highlight nocturnal cough, dyspnea, use of medications such as theophylline and recurrent hypoxemia. The term overlap syndrome is used when we have COPD associated with obstructive sleep apnea (OSA). Overlap syndrome, with a prevalence of 9.5-28%, results in marked hypoxemia during sleep with a greater tendency to hypercapnia, pulmonary hypertension and cor pulmonale, giving these patients a worse prognosis. Objectives: To verify the prevalence of overlap syndrome and to analyze the physiological sleep variables and the quality of life of patients with COPD undergoing a home pulmonary rehabilitation program (PRPD). The study will be conducted in a private clinic, located in the city of Cascavel in the interior of the state of Paraná (PR). Patients will be submitted to clinical evaluation, pulmonary function tests (plethysmography), polysomnography and will respond to quality of life questionnaires, excessive daytime sleepiness and risk for OSA before and after participation in PRPD. Results: The main cause related to the development of COPD was current or previous smoking (83.3% of cases). The most frequent symptom reported was dyspnea (88.8%), followed by productive cough (66.6%) and bronchial secretion (40.0%). By evaluating the clinical history of the cases, a significant number of comorbidities were identified, in addition to COPD, and cardiovascular and neurological diseases were more prevalent. The prevalence of OSA with AHI greater than 5 events was 59.3% (70 patients) and AHI> 15 was 26.2% (31 patients). Conclusion: According to the preliminary data, it was possible to delineate the profile of COPD patients associated with a high prevalence of OSA, with characteristics of an elderly population with multiple comorbidities, suggesting a sleep quality lower than desired.
Introdução: Atualmente, a doença pulmonar obstrutiva crônica (DPOC) é considerada uma importante causa de morbidade e mortalidade, sendo a décima segunda enfermidade mais prevalente no mundo, representando assim um sério problema de saúde pública. É comum pacientes com DPOC apresentarem uma má qualidade do sono. Como causas desta má qualidade do sono destacamos a tosse noturna, dispneia, uso de medicações, como a teofilina e hipoxemia recorrente. O termo overlap syndrome é empregado quando temos a DPOC associada a apneia obstrutiva do sono (AOS). A síndrome da overlap, com uma prevalência entre 9,5-28%, resulta em acentuada hipoxemia durante o sono com maior tendência a hipercapnia, hipertensão pulmonar e cor pulmonale, conferindo a esses pacientes um pior prognóstico. Objetivos: Verificar a prevalência da síndrome de overlap e analisar as variáveis fisiológicas do sono e a qualidade de vida de pacientes com DPOC submetidos a programa de reabilitação pulmonar domiciliar (PRPD). O estudo será realizado em uma clínica privada, localizada na Cidade de Cascavel no interior do estado do Paraná (PR). Os pacientes serão submetidos a avaliação clínica, provas de função pulmonar (pletismografia), polissonografia e responderão a questionários de qualidade de vida, sonolência excessiva diurna e risco para AOS antes e após a participação no PRPD. Resultados: A principal causa relacionada ao desenvolvimento da DPOC foi o tabagismo atual ou prévio (83,3% dos casos). O sintoma mais frequente relatado foi a dispneia (88,8%), seguida de tosse produtiva (66,6%) e secreção brônquica (40,0%). Avaliando-se o histórico clínico dos casos identificou-se, além da DPOC, um número significativo de comorbidades, sendo as cardiovasculares e neurológicas mais prevalentes. A prevalência de AOS com um IAH maior de cinco eventos foi 59,3% (70 pacientes) e IAH > 15 foi de 26,2% (31 pacientes). Conclusão: De acordo com os dados preliminares, pôde-se delinear o perfil de pacientes com DPOC associado a uma alta prevalência de AOS, com características de uma população idosa, com múltiplas comorbidades, sugerindo uma qualidade de sono inferior à desejada.

Introdução: A linfangioleiomiomatose (LAM) é uma neoplasia de baixo grau, frequentemente associada à redução na capacidade de exercício, secundária a múltiplos fatores incluindo alteração de troca gasosa, limitação ventilatória e hiperinsuflação dinâmica (HD). A reabilitação pulmonar (RP) tem benefícios bem estabelecidos em diversas doenças pulmonares crônicas, porém não foi estudada na LAM. Objetivos: Avaliar o impacto de um programa de RP, comparativamente a um grupo controle, em portadoras de LAM, nos seguintes parâmetros: capacidade de exercício (objetivo primário), HD, dispneia, nível de atividade física diária, qualidade de vida, ansiedade e depressão, função pulmonar e força muscular. Metodologia: Ensaio clínico, controlado, não-randomizado, incluindo 21 pacientes com LAM no grupo RP e 19 no grupo controle. A RP teve duração de 3 meses, compreendendo 24 sessões de uma hora de duração (30 minutos de exercício aeróbico e 30 minutos de treinamento de força muscular). A avaliação inicial incluiu um teste de exercício cardiopulmonar (TECP) máximo incremental. As seguintes variáveis foram avaliadas antes e após a RP ou observação (grupo controle): capacidade de exercício, através do tempo até o limite da tolerância (Tlim) no teste de exercício cardiopulmonar (TECP) com carga constante; distância percorrida e dessaturação de oxigênio no teste de caminhada de 6 minutos (TC6M); dispneia (escala de dispneia do Medical Research Council modificada - mMRC, Índice de Dispneia Basal - BDI, e Índice Transicional de Dispneia - TDI); nível de atividade física diária (pedômetro); qualidade de vida relacionada à saúde (Questionário Respiratório de St George\'s, SGRQ); ansiedade e depressão (Escala Hospitalar de Ansiedade e Depressão, HADS); provas de função pulmonar (PFP) e força muscular (uma repetição máxima, 1 RM). Resultados: Não houve diferença nas características basais entre os grupos RP e controle em relação à: idade (45 ± 11 vs. 40 ± 9 anos, p = 0,21), VEF1 (74 ± 30 vs. 70 ± 27% pred, p = 0,67), DLCO (67 ± 33 vs. 64 ± 30% pred, p = 0,79), carga máxima (77 ± 33 vs. 76 ± 35 W, p = 0,93) e O2 pico (17 ± 5 vs. 16 ± 4 ml/ kg/ min; p = 0,52) no TECP incremental. O grupo RP apresentou melhora comparativamente ao grupo controle em (expressos em mediana [intervalo interquartil]): Tlim (169 s [2 - 303 s] vs. -33 s [-129 - 39 s], p = 0,001) e O2 (11% [2 - 26%] vs. -2% [-7 - 5% pred], p = 0,001) no TECP com carga constante, mMRC (0 [-1 - 0] vs. 0 [0 - 1], p < 0,001), TDI (3 [2 - 3] vs. 0 [-2 - 0], p < 0,001), números de passos diários (752 [-694 - 1814] vs. -138 [-830 - 208], p= 0,02), SGRQ (-8 [-16 - 2] vs. 2 [-4 - 5], p = 0,002, distância caminhada no TC6M (59 m [13 - 81] vs. 20 [-12 - 30], p = 0,002) e 1 RM para todos os grupamentos musculares treinados (ex. quadríceps 39% [20 - 70%] vs. 4% [0 - 17%], p <0,001). Houve uma tendência de melhora nos sintomas de depressão e HADS total. HD, dessaturação ao exercício, sintomas de ansiedade e PFP não melhoraram após RP. Houve correlação moderada entre o aumento do Tlim e as variações da mMRC, do O2 de pico no TECP com carga constante, do Borg dispneia isotime e do Borg de pernas isotime. Conclusões: A RP está associada à melhora na capacidade de exercício, dispneia, nível de atividade física diária, qualidade de vida relacionada à saúde e força muscular em pacientes com LAM. O principal mecanismo sugerido é adaptação da musculatura periférica
Introduction: Lymphangioleiomyomatosis (LAM) is a low-grade neoplasm, which is frequently associated with reduced exercise capacity, secondary to multiple factors including gas exchange impairment, ventilatory limitation and dynamic hyperinflation (DH). Pulmonary rehabilitation (PR) has proven benefits in many chronic pulmonary diseases but it was not evaluated in LAM. Objectives: To evaluate the impact of a PR program in women with LAM, when compared to a control group, in the following parameters: exercise capacity (primary outcome), DH, dyspnea, daily physical activity, quality of life, anxiety and depression, lung function and muscle strength. Methods: A non-randomized controlled clinical trial that included 21 LAM patients in the PR group and 19 in the control group. The PR program lasted 3 months, comprising 24 sessions of 1 hour (30 minutes of aerobic exercise and 30 minutes of muscle strength training). The initial evaluation included a maximum incremental cardiopulmonary exercise test (CPET). The following variables were assessed before and after PR or observation (control group): exercise capacity using the tolerable limit duration (Tlim) in constant work rate (CWR) exercise testing; walking distance and oxygen desaturation (six-minute walk test, 6MWT), dyspnea (Modified Medical Research Council Dyspnea Scale -mMRC; Basal Dyspnea Index - BDI, and Transitional Dyspnea Index -TDI); daily physical activity (pedometer); health-related quality of life (St George\'s Respiratory Questionnaire, SGRQ); anxiety and depression (Hospital Anxiety and Depression Scale, HADS); pulmonary function tests (PFT) and muscle strength (one-repetition maximum, 1RM). Results: There was no difference in baseline characteristics between the PR and control groups related to age (45 ± 11 vs. 40 ± 9 years, p = 0.12), FEV1 (74 ± 30 vs. 70 ± 27% pred, p = 0.67), DLCO (67 ± 33 vs. 64 ± 30% pred, p = 0.79), maximum work rate (77 ± 33 vs. 76 ± 35 W, p = 0.93) and peak O2 (17 ± 5 vs. 16 ± 4 ml/ kg/ min; p = 0.52) in incremental CPET. The PR group had a significant improvement when compared to the control group in (expressed in median [interquartile range]): Tlim (169 s [2 - 303 s] vs. -33 s [-129 - 39 s], p = 0.001) and O2 (11% [2 - 26%] vs. -2% [-7 - 5% pred], p = 0.001) in CWR exercice testing, mMRC (0 [-1 - 0] vs. 0 [0 - 1], p< 0.001), ( TDI (3 [2 - 3] vs.0 [-2 - 0], p< 0.001), daily steps (752 [-694 - 1814] vs. -138 [-830 - 208], p= 0.02), SGRQ (-8 [-16 - 2] vs. 2 [-4 - 5], p = 0.002), walking distance in 6MWT (median 59 m [13 - 81] vs. 20 [-12 - 30], p = 0.002) and 1 RM for all muscle groups trained (ex. quadriceps 39% [20 - 70%] vs. 4% [0 - 17%], p <0.001). There was a trend towards improvement in depression symptoms and total HADS. DH, desaturation during exercise, anxiety symptoms and PFT did not improve after PR. There was a moderate correlation between increased Tlim and variations of mMRC, peak O2 in CWR exercise testing, Borg dyspnea isotime and Borg leg discomfort isotime. Conclusions: PR is associated with improvements in exercise capacity, dyspnea, daily physical activity, health-related quality of life and muscle strength in patients with LAM. The main mechanism suggested is peripheral muscles adaptation

Introdução: As alterações da mecânica diafragmática e a alta atividade dos músculos da caixa torácica estão associadas com maior sensação de dispnéia em pacientes com DPOC. Tem sido demonstrado que a respiração diafragmática (RD) aumenta a mobilidade abdominal durante o padrão diafragmático voluntário, porém, até o presente momento, nenhum estudo investigou as mudanças na mobilidade abdominal adotadas naturalmente. O objetivo desse estudo foi investigar os efeitos de um programa de treinamento de respiração diafragmática (PTRD) na mobilidade tóraco-abdominal, mobilidade diafragmática e capacidade funcional de pacientes com DPOC. Método: Trinta pacientes com DPOC (VEF1 42 +/- 13% do predito) foram alocados aleatoriamente para o grupo treinamento (GT) ou grupo controle (GC). O GT completou um PTRD supervisionado de 4 semanas (3 sessões semanais individualizadas). A efetividade do treinamento foi avaliada por meio da mensuração da relação da amplitude de movimento da caixa torácica pelo abdômen (CT/ABD; variável primária) e da mobilidade diafragmática (variável secundária). A relação CT/ABD foi quantificada utilizando a pletismografia respiratória por indutância durante RD voluntária e respiração natural (RN) e a mobilidade diafragmática foi determinada por avaliação ultra-sonográfica. O teste de caminhada em 6 minutos (TC6min) e os fatores de saúde relacionados à qualidade de vida (FSRQV) também foram avaliados. Resultados: Apenas os pacientes do GT apresentaram uma melhora na mobilidade diafragmática (18,8%) e uma redução na relação CT/ABD durante RN (26,1%) e RD voluntária (28,3%), sugerindo que a mobilidade abdominal aumentou em ambas as condições. Também foram observadas melhoras no TC6min e nos FSRQV no GT. Não foi observada diferença no GC para nenhuma variável mensurada. Conclusões: O PTRD para pacientes com DPOC induziu um aumento do recrutamento diafragmático durante a respiração natural resultando em melhora da capacidade funcional
Background: Impairment of diaphragm mechanics and enhanced activity of the chest wall muscles are associated with increased dyspnea in COPD patients. Diaphragmatic breathing (DB) has been suggested to improve abdominal motion but only during voluntarily DB, and no controlled studies have investigated the naturally adopted change in abdominal motion. The aim of this study was to investigate the effects of a diaphragmatic breathing training program (DBTP) on thoracoabdominal motion, diaphragmatic mobility and functional capacity in COPD patients. Methods: Thirty subjects (FEV1 42+/-13% predicted) were randomly allocated to either training (TG) or control group (CG). TG completed a 4-week supervised DBTP (3 individualized weekly sessions). Effectiveness was assessed by amplitude of the rib cage to abdominal motion ratio (RC/ABD ratio; primary outcome) and diaphragmatic mobility (secondary outcome). The RC/ABD ratio was measured using respiratory inductive plethysmography during voluntarily DB and natural breathing (NB). Diaphragmatic mobility was measured by ultrasonography. A 6-minute walk test (6MWT) and health-related quality of life (HRQoL) were also evaluated. Results: Only COPD patients from the TG demonstrated an improvement in diaphragmatic mobility (18.8%) and a reduction of the RC/ABD ratio during both NB (26.1%) and voluntarily DB (28.3%), suggesting that the abdominal motion improved in both conditions. An improvement in the 6MWT and in HRQoL was also observed in the TG. No differences were found in the CG for any measured outcome. Conclusions: We concluded that DBTP for COPD patients induced increased diaphragm recruitment during natural breathing resulting in an improvement in functional capacity

Pectus excavatum é a deformidade congênita na parede torácica anterior mais comum e seu tratamento é essencialmente cirúrgico. Tratamentos cirúrgicos e repouso prolongado no leito levam a alterações metabólicas, músculoesqueléticas, cardiovasculares e respiratórias, que podem prolongar o tempo necessário para a recuperação funcional dos pacientes no pós-operatório, aumentar o tempo de internação e os custos em saúde. A reabilitação precoce após cirurgias, com a realização de exercícios físicos e respiratórios, reduzir estes efeitos adversos, garante melhor recuperação pós-operatória, com aumento da independência dos pacientes, maior bem-estar psicológico e melhores resultados funcionais. O objetivo deste estudo foi avaliar se os pacientes submetidos a reabilitação precoce após correção cirúrgica de Pectus excavatum pela técnica de Nuss apresentam melhor capacidade funcional de exercício e função pulmonar no dia da alta hospitalar quando comparados com os pacientes submetidos a cuidados convencionais. Os Candidatos a correção cirúrgica foram alocados aleatoriamente em 2 grupos: o grupo reabilitação precoce (GRP), que iniciou a intervenção logo após a cirurgia e o grupo de cuidados convencionais (GC), que recebeu os cuidados de rotina da instituição. O teste de função pulmonar por meio da espirometria simples e a avaliação da capacidade funcional de exercício pelo teste de caminhada de seis minutos (TC6), foram realizados antes da cirurgia (pré-operatório) e no dia da alta hospitalar (pós-operatório). Quarenta pacientes foram analisados, 20 em cada grupo. No teste de função pulmonar, todos os pacientes apresentaram redução significativa dos valores de CVF, VEF1 e PFE no pós-operatório, sem diferença entre os grupos. Todos os pacientes apresentaram redução significativa da distância percorrida no TC6 pós-operatório comparada com a distância percorrida no pré-operatório (p < 0,005). Houve diferença estatisticamente significante entre o GRP e GC na avaliação pós-operatória (506.26 ± 66.54 vs 431.11 ± 75.61, p=0.02), e a diferença entre as distâncias percorridas no pré-operatório e no dia da alta hospitalar foi significativamente menor no GRP em comparação com o GC (76.57 ± 49.41 vs 166.82 ± 70.13, p < 0.001). Concluímos que os pacientes submetidos a reabilitação precoce após técnica de Nuss apresentam melhor capacidade funcional de exercício no dia da alta hospitalar em comparação com os pacientes do grupo convencional, sem diferença da função pulmonar entre os grupos
Pectus excavatum is the most common congenital chest wall deformity and its treatment is essentially surgical. Surgical treatments and postoperative bed rest lead to metabolic, musculoskeletal, cardiovascular and respiratory alterations, with the possibility of prolonging the time required for postoperative patient recovery, increasing hospitalization time and health expenditure. Early rehabilitation after surgeries, which involves physical and breathing exercises, reduces these adverse effects and ensure better postoperative recovery, with increased independence of patients, greater psychological well-being and better functional outcomes. The objective of this study was to assess whether patients undergoing early rehabilitation after Pectus excavatum repair using the Nuss procedure have better functional exercise capacity and lung function on hospital discharge day compared with patients undergoing conventional care. Patients were randomly allocated into two groups: the early rehabilitation group (ERG) which started rehabilitation after surgery and the group of conventional care (CG) which received routine care of the institution. The lung function was assessed by simple spirometry and the functional exercise capacity by the 6-minute walk test (6MWT) were performed before surgery (preoperative) and in hospital discharge day (postoperative). Forty patients were evaluated, 20 in each group. All patients presented a significant reduction in FVC, FEV1 and PEF in the postoperative lung function test and there was no statistically significant difference between groups. All patients showed significant reduction in postoperative distance walked in 6MWT compared with the preoperative distance (p < 0.005). There was statistically significant different in functional exercise capacity between the ERG and CG in the postoperative evaluation (506.26 ± 66.54 vs 431.11 ± 75.61, p=0.02) and the difference between distance walked in the preoperative and postoperative period was significantly lower in the ERC compared to the CG (76.57 ± 49.41 vs 166.82 ± 70.13, p < 0.001). We conclude that patients undergoing early rehabilitation after Nuss procedure presented better postoperative functional exercise capacity in hospital discharge day compared to patients in the conventional group, with no difference in lung function between groups

Background: Chronic obstructive pulmonary disease (COPD) is currently the fourth major cause of morbidity and mortality worldwide. Pulmonary rehabilitation (PR) is currently recommended as a fundamental intervention for the management of stable COPD. However, its access is very restricted. Although, the potential of improvement has been used as a criterion to determine patients’ access to PR, the response is highly dependent on the outcomes measures used. Moreover, there is still no consensus on the minimum outcomes that should be assessed (Core Outcome Set – COS) in PR. A COS has the potential to improve consistency among trials and lessen the risk of outcome reporting bias, by including outcomes relevant to different stakeholders. Aim: To explore outcomes of PR valued by patients, informal carers (IC) and health professionals (HP). Methods: Semi-structured interviews were conducted with 12 patients (83.3%♂, 70.8±5.2 years, 50.7±17.5 FEV1pp, 27.2±3.9 BMI), 11 IC (18.2%♂, 68.4±7.9 years, 5.3±7.0 years of caregiving) and 10 HP (20%♂, 40.7±14.3 years, 6.7±9.7 years of experience). Data were analysed following a content analysis approach and thematic analysis afterwards with NVivo software. Results: This study generated 44 outcomes to be assessed in PR. Five relevant themes to all stakeholders were generated from the analysis: having a healthy mind in a healthy body; I can(‘t) do it; feeling fulfilled; knowing more, doing better and avoiding doctors and expenses. Although perspectives were mostly consensual among stakeholders, some outcomes (i.e., pulmonary function) were only valued by HP, whereas patients and IC valued PR for its impact on their day-to-day lives and role in the community. Although some participants did not recognize PR effects in key outcomes reported in the literature such as exercise tolerance, all participants reported at least one positive outcome. Conclusions: This study identified a set of outcomes relevant for the different stakeholders involved in PR, that are not consensual. These results could contribute to the development of a future COS for PR in patients with COPD
Enquadramento: A doença pulmonar obstrutiva crónica (DPOC) é atualmente a quarta principal causa de morbilidade e mortalidade no mundo. A reabilitação respiratória (RR) é uma intervenção fundamental para a gestão da DPOC mas de acesso escasso. Apesar do “potencial” de melhoria do doente ser comumente utilizado como critério de acesso à RR, esta melhoria é altamente dependente das medidas que são utilizadas na RR. Atualmente, não existe um consenso relativamente ao conjunto mínimo de domínios (Core Outcome Set – COS) que devem ser avaliados nos programas de RR de pessoas com DPOC. Um COS tem o potencial de melhorar a consistência na literatura e diminuir o risco de viés nos resultados reportados, ao incluir domínios considerados relevantes para os diferentes intervenientes na RR. Objetivo: Explorar os domínios da RR valorizados por doentes, cuidadores informais (CI) e profissionais de saúde (PS). Métodos: Realizaram-se entrevistas semiestruturadas a 12 doentes com DPOC (83.3%♂, 70.8±5.2 anos, 50.7±17.5 VEMSpp, 27.2±3.9 IMC), 11 CI (18.2%♂, 68.4±7.9 anos, 5.3±7.0 anos a cuidar) e 10 os (20%♂, 40.7±14.3 anos, 6.7±9.7 anos de experiência). Os dados foram analisados através da análise qualitativa ao conteúdo e posteriormente através da análise temática, através do software NVivo. Resultados: Este estudo gerou 44 domínios a serem avaliados na RR. Cinco temas, relevantes para todas as partes interessadas, foram gerados pela análise: ter uma mente sã num corpo são, eu (não) consigo, sentir-se realizado, saber mais para fazer melhor e evitar médicos e despesas. Apesar das perspetivas terem sido maioritariamente consensuais entre os participantes, alguns domínios (i.e., função pulmonar) foram valorizados apenas pelos PS. Para os doentes e CI, a RR foi principalmente valorizada pelo seu impacto na vida diária e papel na comunidade. Apesar de alguns participantes não reconhecerem benefícios da RR em domínios-chave da literatura, como a tolerância ao esforço, todos os participantes reconheceram pelo menos um benefício da RR. Conclusão: Este estudo identificou um conjunto de domínios considerados relevantes para a RR de pessoas com DPOC, pelos diferentes intervenientes desta intervenção, que não são consensuais. Estes resultados poderão contribuir para o desenvolvimento futuro de um COS para programas de RR em pessoas com DPOC

RESUMO: A reabilitação respiratória (RR) é uma intervenção abrangente e interdisciplinar dirigida aos doentes respiratórios crónicos e inclui o treino de exercício, programas de educação e de modificação comportamental, entre outros, desenhados individualmente para melhorar o desempenho físico e psicossocial e promover a adesão a longo prazo a comportamentos promotores de saúde. A doença pulmonar obstrutiva crónica (DPOC) é uma doença comum, afetando cerca de 210 milhões de pessoas em todo o mundo, com elevada mortalidade e com custos económicos significativos decorrentes do agravamento progressivo da doença, das hospitalizações e de reinternamentos frequentes. Apesar do crescente conhecimento da DPOC e do papel da RR nos benefícios para a saúde, existem aspetos ainda não esclarecidos que têm impacto na prática clínica e de investigação e nas decisões das autoridades de saúde. A primeira parte desta tese focou a DPOC e o seu impacto negativo e incluiu: o estudo da prevalência da DPOC em Portugal; os fatores clínicos e funcionais que se associam à mortalidade em doentes com DPOC avançada; a morbilidade, impacto funcional e risco dos doentes se tornarem dependentes para as atividades diárias e a influência da inflamação sistémica. A prevalência estimada da DPOC de 14,2% indica que esta é uma doença comum em Portugal e alerta para a necessidade de uma maior sensibilização da população, dos profissionais de saúde e autoridades de saúde com vista a um diagnóstico precoce e à alocação dos recursos terapêuticos adequados. A elevada taxa de mortalidade em doentes com DPOC avançada - 36,6% em 3 anos - associou-se a insuficiência respiratória, a elevado número de exacerbações, ao cancro do pulmão e a reduzida capacidade funcional para a marcha, salientando a importância da referenciação precoce para RR, a identificação e o tratamento das comorbilidades e a prevenção das exacerbações. A aplicação de um questionário que avaliou as atividades da vida diária básicas e instrumentais, permitiu identificar um marcador clínico do risco de dependência, complementando as avaliações funcionais e associando-se a outros marcadores de mau prognóstico, como as exacerbações. Em doentes com DPOC, com FEV1 médio de 46,76% (desvio padrão: 20,90%), 67% da categoria D do GOLD, verificou-se uma associação positiva entre a expressão de genes inflamatórios avaliada pela reação em cadeia da polimerase (ARN mensageiro de IFNg, IL1b, IL6, IL8, TNFa, TGFb1, iNOS) e o índice de massa corporal em repouso, acentuando-se após o exercício. Este estudo aponta a inflamação como o potencial elo de ligação entre a obesidade e a inflamação sistémica em doentes com DPOC. A segunda parte da tese focou a RR, nomeadamente os seus efeitos em doentes das categorias GOLD A, B, C e D; o impacto das comorbilidades nos resultados da RR e os resultados de diferentes intensidades de treino aeróbio. Após o programa de RR, verificaram-se melhorias significativas na capacidade de exercício funcional e de endurance e no estado geral de saúde dos doentes de todas as categorias GOLD. Esta classificação não distingue os doentes que melhor poderão beneficiar desta intervenção, indicando que devem ser referenciados para RR, os doentes sintomáticos ou com repercussão na qualidade de vida, independentemente da categoria da DPOC a que pertençam. A prevalência das comorbilidades no grupo de doentes com DPOC que é referenciado para RR, é elevada, sendo as mais frequentes, as cardiovasculares, as respiratórias e as psicológicas. Apesar de poderem diminuir o impacto da RR, os resultados desta foram semelhantes independentemente do número de comorbilidades. A identificação e o tratamento sistemáticos das comorbilidades conferem maior segurança clínica a esta intervenção terapêutica a qual, por apresentar bons resultados, não deve limitar a referenciação dos doentes. Com o programa de RR, verificou-se melhoria significativa em todos os resultados centrados no doente para ambas as intensidades de treino aeróbio, a 60% e a 80% da potência aeróbica máxima (Wmax), com melhoria do estado geral de saúde, nos sintomas e na capacidade para o exercício, o que questiona a indicação sistemática de elevadas intensidades de treino em doentes com DPOC para a obtenção de benefícios a curto prazo. Na terceira e última parte da tese foi estudado o papel da atividade física na DPOC, focando os fatores que influenciam a atividade física diária; a evolução da capacidade funcional e o estado de saúde 2 anos após um programa de RR e o papel da telemonitorização na quantificação e monitorização da atividade física. Confirmámos que os doentes com DPOC são marcadamente sedentários e os fatores que se associaram ao sedentarismo nestes doentes foram a dispneia e a distância percorrida na prova de marcha de seis minutos. Este estudo sublinha a importância do controlo sintomático, nomeadamente da dispneia, bem como, mais uma vez, o potencial papel da reabilitação respiratória no aumento da capacidade funcional para o exercício e na aquisição de hábitos de vida fisicamente ativa. Verificámos que, apesar de os doentes com DPOC apresentarem benefícios clinicamente significativos na capacidade funcional para o exercício e no estado geral de saúde com o programa de RR, apenas os que se mantêm ativos, podem, no final dos dois anos de seguimento, manter os efeitos benéficos desse programa. O sistema de telemonitorização que combina a oximetria e a quantificação da atividade física provou ser clinicamente útil na avaliação da necessidade de oxigenoterapia de longa duração (OLD) e na aferição do débito de oxigénio em repouso, no esforço e no sono, podendo contribuir para uma melhor adequação da prescrição da OLD. A monitorização dos níveis de atividade física regular é um importante instrumento de avaliação dos programas de RR e o seu uso potencial na telereabilitação permitirá prolongar a eficácia dos programas e reduzir os custos associados aos cuidados de saúde.---------------------------------------------------------------------------------------------------ABSTRACT: Pulmonary rehabilitation (PR) is a comprehensive interdisciplinary intervention that includes, but is not limited to, exercise training, education, and behavior change, individually designed to improve physical and psychological conditions of people with chronic respiratory disease and to promote long-term adherence to health-enhancing behaviors. Chronic obstructive pulmonary disease (COPD) is a common disease, affecting about 210 million people worldwide, with high mortality and significant health-related costs due to disease progression, hospitalizations and frequent hospital readmissions. Although the increasing knowledge about COPD and benefitial outcomes of PR, some aspects with impact in clinical practice, research and health authorities’ decisions, remain to be clarified. The first part of this thesis focused on COPD and its negative impact, including the study of COPD prevalence in Portugal; clinical and functional factors associated with mortality in advanced COPD patients; morbidity, functional impact and risk of others’ dependance to perform activities of daily living; and the role of systemic inflammation. The evidence of 14.2% estimated COPD prevalence as a common disease in Portugal raises the need of an increasing awareness of population, health care professionals and health authorities towards an earlier diagnosis and apropriate treatment resources allocation. High mortality in patients with advanced COPD – 36.6% in 3 years - was associated with respiratory failure, high frequency of exacerbations, lung cancer and a low functional capacity in walking. This highlightens the importance of an earlier referral to PR, comorbidity identification and treatment, and prevention of exacerbations. A questionnaire evaluated basic and instrumental activities of daily living, and identified a clinical marker of the risk of becoming dependent. This clinical marker complemented other functional evaluations and was associated with prognosis markers such as the number of exacerbations. In COPD patients with a mean FEV1 46.76% (SD 20.90%), 67% belonging to GOLD grade D, we found a positive association between inflammatory gene expression evaluated by polymerase chain reaction (IFNg, IL1b, IL6, IL8, TNFa, TGFb1, iNOS RNA messenger) and body mass index at rest, and a further increase with exercise. This study evidenced obesity as one potential link between COPD and systemic inflammation. The second part of this thesis focused PR, namely its outcomes in patients of GOLD categories A, B, C and D; comorbidities impact in PR outcomes, and the impact of different exercise training intensities in patient related outcomes. xviii With PR intervention, we found significant improvement in functional exercise capacity, endurance exercise capacity and health status in patients of all GOLD categories. This classification did not differentiate which patients would benefit more from PR, hence all symptomatic patients with a negative impact in health status should be referred to PR, regardless of the GOLD category they belong to. There is a high prevalence of comorbidities in COPD patients referred to PR, being cardiovascular, respiratory and psychological, the most prevalent. Although some comorbidities might reduce PR impact, the results were similar regardless of the number of comorbidities. Systematic comorbidities identification and treatment provides safety to PR intervention, and its good results should not preclude patients referral. With PR intervention we found a significant improvement in all patient reported outcomes for exercise training intensities at 60% and 80% maximum work rate (Wmax), namely in health status, symptoms and exercise capacity. These findings challenge the current systematic indication of high exercise training intensities to achieve PR short-term benefits. In the third and last part of the thesis, the role of physical activity in COPD was studied, focusing factors that may influence daily physical activity; the evolution of functional capacity and health status two years after a PR program, and the role of a telemonitoring system in physical activity quantification and monitoring. We confirmed that COPD patients are markedly inactive and factors associated with a sedentary lifestyle are dyspnea and 6 minute walking distance. This study emphasized the importance of symptom control, namely of dyspnea, as well as, once again, the potential role of PR in functional exercise improvement and in integrating physically active habits in daily life. We verified that, although COPD patients improve functional exercise capacity and health status after a PR program, only those who kept physical activity habits were able to maintain those effects after 2 years of follow-up. A telemonitoring system that combines oximetry and physical activity quantification proved to be clinically useful in the evaluation of long-term oxygen therapy (LTOT) indication, as well as in the titration of oxygen levels at rest, exertion, and sleeping, which might contribute to a more adequate LTOT prescription. Monitoring of daily physical activity levels is an important PR evaluation instrument and its potential use in telerehabilitation might allow lengthening programs efficacy, while reducing health-care costs.

Background: The effectiveness of pulmonary rehabilitation in patients with Chronic Obstructive Pulmonary Disease（COPD）has been proven, but its benefits would be faded away if regular exercise cannot be maintained after the training program. Biofeedback improving patients’ self-efficacy in exercise has been found in contemporary studies, but the truly thoughts and experiences related to biofeedback in patients with COPD are still lacking. Aims: To understand COPD patients’ self-awareness on the psychological and physiological changes, the regular exercise maintaining, and their psychological and physiological wellbeing after completing biofeedback combined with pulmonary rehabilitation exercise training. Methods: From February 20, 2014 to December 30, 2014, 12 patients with COPD who completed the 4-week training program of combined biofeedback with pulmonary rehabilitation exercise in a medical center in the northern Taiwan were interviewed. Subjects were received two interviews at the time of right after the training program and 6 months after the training. The information were collected by in-depth interviews with the semi-structured interviews guide and transcripts were analyzed by the method of Graneheim & Lundman’s content analysis. Results: In the present study, six themes described subjects’ thoughts and experiences related to biofeedback combined with pulmonary rehabilitation exercise at the time after the training were identified in the transcripts of : the motivation of engaging the training program, special experiences come with the training program, positive progressing in health status, initiating the healthy behaviors, expanding exercise benefits, the additional effects of biofeedback training. In addition, five themes were identified from the interview transcripts of 6 months after the training in these subjects: maintaining the positive physiological and psychological impacts from training program, further improving in healthy life behaviors, motivating to maintain the exercise effects, perceived the factors to maintain the regular exercise, perceived barriers to maintain the regular exercise. Conclusion: After received the biofeedback combined with pulmonary rehabilitation exercise training, patients with COPD experienced the improvement of their physiological conditions, and willing to execute healthy behaviors. In addition, patients perceived benefits from biofeedback and able to self-practice the breathing exercise at home. At 6 months after training, our subjects had realized their own positive changes, established their own way to maintain the regular exercise, and identified the factors against them from the regular exercise. The results of this study can be a reference for health care provider in taking care of patients with COPD, involving an efficient intervention and providing a better quality of care accordingly.

Background: Lobectomy of lungs is the primary treatment for non-small cell lung cancer. Pulmonary rehabilitation enhancing lung expansion and ventilation may help to improve oxygenation and reduce postoperative lung complications. Aim: The study was to test the efficacy of a pulmonary rehabilitation intervention on oxygenation, pulmonary complications in lung cancer patients with lung resection surgery.Methods: 90 lung cancer patients scheduled for a lung resection surgery were recruited and randomized to the control or intervention group. The intervention group practiced pulmonary rehabilitation exercise in home for 5 days before the surgery and post-operative pulmonary rehabilitation while in the hospital. Data on six minute walk distance and level of fatigue were collected at the baseline and before discharge. Descriptive analyses were used to describe patients’ demographics, disease variables, and outcome variables. The Chi-square, T-test, and GEE were used to test the efficacy of the study interventions. Results: Two groups were similar at baseline. The result of GEE showed signification group, time, and group by time interaction effects on S/F ratio, indicating the intervention group had better oxygenation with a β value of 34.13 (Wald X2 = 8.32, p = 0.04) compared with the control group. There was only one patient in the intervention group reported clinical significant postoperative lung complications (X2 = 8.389, p = 0.004 ) than what was reported in the control group. The average duration of chest drainage in the intervention group was 2.00 days (t =-2.324 , p = 0.022).Conclusion: The study results were provided evidence of the pulmonary rehabilitation intervention for improved oxygenation, reduced postoperative pulmonary complications in lung cancer with lung resection patients.

The purposes of this study were to explore the effect of modified abdominal breathing (MAB) training followed by Tai-Chi-Qui-Gong (TCQG) exercise training on pulmonary function, exercise capacity, and quality of life in patients after lobectomy. The quasi-experimental design was utilized in this study. Purposive sampling method was adopted to include forty subjects from a chest surgical ward of a medical center in Taipei city. The all signed the informed consent and were participated voluntarily. Subjects were randomly assigned into experimental group and the control group, twenty patients each. Subjects in the experimental group received a class on modified abdominal breathing and 10 motions of TCQG two days before surgery. They were coached to conduct MAB immediately after removed endotracheal tube in the recovery room. After returning to the general ward, they practiced 10 motions of TCQG exercise on the first day after lobectomy. The control group received standard post-lobectomy care which did not include MAB and exercise. All of two groups were measured pulmonary function and the distance of six minutes'' walk two days prior to the operation, one week after operation, and one month after operation, besides, the questionnaire of quality of life was measured also in the two days before operation and one month after operation. The data were analyzed with SPSS Windows 10.0 statistical software. The major statistical procedures applied in data management included: independent-T test , repeated-measures ANOVA and Pearson Correlation test. The p value level of <0.05 was used as the significant level. The results indicated that: subjects in the experimental group had significant improvement in their tidal volume and 6 minutes walking distance (6MWD) post lobectomy, while subjects in the control group did not. The 6MWD of the subjects in the experimental group resume to the preoperative status at the end of first week, and was even better one month after. The quality of life of the subjects in the experimental group was significantly better than it was in the control group postoperatively. Age was the major factor determining the postoperative recovery of pulmonary functions and physical capability. Physical capability had essential impact of the perceive quality of life. The finding indicated that modified abdominal breathing training followed by Tai-Chi-Qui-Gong exercise training was effective in improving pulmonary function, exercise capacity, and quality of life of the patient post lobectomy. This rehabilitation training is worth of adoption by nurses and doctors in taking care of patients receiving lobectomy surgery.
