Este estudo teve como objetivos avaliar a qualidade de vida relacionada à saúde (QVRS) e o bem-estar espiritual (BEE) de pacientes com doença pulmonar obstrutiva crônica (DPOC) e analisar as relações entre QVRS e BEE. As versões em português do Seattle Obstructive Lung Disease Questionnaire (SOLDQ) e do Spiritual Well-Being Scale (SWBS) foram aplicadas por entrevista a 70 pacientes com DPOC em tratamento ambulatorial. Os domínios do SOLDQ com menor e maior escores foram: Função Física (37,29±17,19) e Satisfação com o Tratamento (68,75±28,05). O escore médio de 94,87±13,56 indica um nível moderado de BEE. O escore total do SWBS e o da subescala Bem-Estar Religioso correlacionaram-se positivamente com o domínio Satisfação com o Tratamento (p=0,007 e p=0,002, respectivamente). Correlação negativa foi encontrada entre Bem-Estar Religioso e Função Física (p=0,05). Pacientes com maior bem-estar religioso estavam mais satisfeitos com o tratamento e tinham pior funcionamento físico.; This study aimed to evaluate health related quality of life (HRQL) and spiritual well-being (SWB) of patients with chronic obstructive pulmonary disease (COPD) and to investigate the relationship between HRQOL and SWB. Seventy outpatients with COPD were interviewed using Portuguese versions of the Seattle Obstructive Lung Disease Questionnaire (SOLDQ) and Spiritual Well-Being Scale (SWBS). SOLDQ domains with lowest and highest scores were Physical Function (37.29±17.19) and Treatment Satisfaction (68.75±28.05). Total score of the SWBS was 94.87±13.56...

OBJETIVO: Estimar a prevalência e fatores associados à doença pulmonar obstrutiva crônica. MÉTODOS: Estudo transversal, de base populacional com 1.441 indivíduos de ambos os sexos e com 40 anos de idade ou mais no município de São Paulo, SP, entre 2008 e 2009. As informações foram coletadas por meio de entrevistas domiciliares e os participantes foram selecionados a partir de amostragem probabilística, estratificada por sexo e idade, e por conglomerados em dois estágios (setores censitários e domicílios). Foi realizada regressão múltipla de Poisson na análise ajustada. RESULTADOS: Dos entrevistados, 4,2% (IC95% 3,1;5,4) referiram doença pulmonar obstrutiva crônica. Após análise ajustada, identificaram-se os seguintes fatores independentemente associados ao agravo: número de cigarros fumados na vida (> 1.500/nenhum) RP = 3,85 (IC95%: 1,87;7,94), cansar-se com facilidade (sim/não) RP = 2,61 (IC95% 1,39;4,90), idade (60 a 69 anos/50 a 59 anos) RP = 3,27 (IC95% 1,01;11,24), idade (70 anos e mais/50 a 59 anos) RP = 4,29 (IC95% 1,30;14,29), problemas de saúde nos últimos 15 dias (sim/não) RP = 1,31 (IC95% 1,02;1,77), e atividade física no tempo livre (sim/não) RP = 0,57 (IC95% 0,26;0,97). CONCLUSÕES: A prevalência da doença pulmonar obstrutiva crônica é elevada e está associada ao uso do tabaco e idade acima de 60 anos. Os problemas de saúde freqüentes e redução da atividade física no tempo livre podem ser considerados conseqüências dessa doença.; OBJECTIVE: To assess the prevalence of chronic obstructive pulmonary disease and related risk factors.

OBJECTIVE: The potential influence of magnesium on exercise performance is a subject of increasing interest. Magnesium has been shown to have bronchodilatatory properties in asthma and chronic obstructive pulmonary disease patients. The aim of this study was to investigate the effects of acute magnesium IV loading on the aerobic exercise performance of stable chronic obstructive pulmonary disease patients. METHODS: Twenty male chronic obstructive pulmonary disease patients (66.2 +/- 8.3 years old, FEV1: 49.3 +/- 19.8%) received an IV infusion of 2 g of either magnesium sulfate or saline on two randomly assigned occasions approximately two days apart. Spirometry was performed both before and 45 minutes after the infusions. A symptom-limited incremental maximal cardiopulmonary test was performed on a cycle ergometer at approximately 100 minutes after the end of the infusion. ClinicalTrials.gov: NCT00500864 RESULTS: Magnesium infusion was associated with significant reductions in the functional residual capacity (-0.41 l) and residual volume (-0.47 l), the mean arterial blood pressure (-5.6 mmHg) and the cardiac double product (734.8 mmHg.bpm) at rest. Magnesium treatment led to significant increases in the maximal load reached (+8 w) and the respiratory exchange ratio (0.06) at peak exercise. The subgroup of patients who showed increases in the work load equal to or greater than 5 w also exhibited significantly greater improvements in inspiratory capacity (0.29 l). CONCLUSIONS: The acute IV loading of magnesium promotes a reduction in static lung hyperinflation and improves the exercise performance in stable chronic obstructive pulmonary disease patients. Improvements in respiratory mechanics appear to be responsible for the latter finding.

Yamaguti WP, Claudino RC, Neto AP, Chammas MC, Gomes AC, Salge TM, Moriya HT, Cukier A, Carvalho CR. Diaphragmatic breathing training program improves abdominal motion during natural breathing in patients with chronic obstructive pulmonary disease: a randomized controlled trial. Arch Phys Med Rehabil 2012;93:571-7. Objective: To investigate the effects of a diaphragmatic breathing training program (DBTP) on thoracoabdominal motion and functional capacity in patients with chronic obstructive pulmonary disease. Design: A prospective, randomized controlled trial. Setting: Academic medical center. Participants: Subjects (N=30; forced expiratory volume in Is, 4270 +/- 13% predicted) were randomly allocated to either a training group (TG) or a control group (CG). Interventions: Subjects in the TG completed a 4-week supervised DBTP (3 individualized weekly sessions), while those in the CG received their usual care. Main Outcome Measures: 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 voluntary diaphragmatic breathing and natural breathing. Diaphragmatic mobility was measured by ultrasonography. A 6-minute walk test and health-related quality of life were also evaluated. Results: Immediately after the 4-week DBTP...

A Apnéia Obstrutiva do Sono (AOS) e a Doença Pulmonar Obstrutiva Crônica (DPOC) são condições clínicas comuns, particularmente na população de idosos, e portanto é de se esperar que um grande número de pacientes com DPOC apresente AOS. Os pacientes portadores da DPOC podem ser divididos em dois tipos clínicos, A e B. O segundo apresenta características clínicas sugestivas da AOS. A prevalência da AOS entre os portadores da DPOC permanece controversa e existem poucos estudos sistemáticos correlacionando a presença da AOS com o tipo clínico da DPOC. Os objetivos primários do nosso estudo foram: (1) determinar a prevalência da AOS em uma população de DPOC e (2) determinar os preditores de risco desta população para AOS. Identificamos 120 pacientes regularmente matriculados no ambulatório de DPOC da Disciplina de Pneumologia da Faculdade de Medicina da Universidade de São Paulo que preenchiam os critérios para o diagnóstico da DPOC segundo definição da American Thoracic Society. Excluímos os pacientes em programa de oxigenoterapia domiciliar (28 pacientes). Realizamos polissonografia nos 50 primeiros pacientes. Todos foram estudados pelos seguintes métodos: mensuração de dados antropométricos e circunferência do pescoço...

Tromboembolia pulmonar aguda e exacerbação aguda de doença pulmonar obstrutiva crônica são doenças comuns. A doença pulmonar obstrutiva crônica é um fator clínico de risco para tromboembolia pulmonar aguda. As apresentações clínicas da tromboembolia pulmonar aguda e da exacerbação aguda da doença pulmonar obstrutiva crônica freqüentemente mimetizamse tanto que pode ser difícil distingui-las. Anormalidades estruturais nos pulmões com doença pulmonar obstrutiva crônica tornam também difícil a interpretação de testes não invasivos de diagnóstico, como o mapeamento de ventilação e perfusão pulmonares. Assim, diagnosticar tromboembolia pulmonar aguda em pacientes com doença pulmonar obstrutiva crônica é uma tarefa desafiadora. Com o objetivo de atualizar o assunto e oferecer sugestões de conduta, nós avaliamos artigos abordando este tema, incluindo relatos e séries de casos, abordagens diagnósticas de tromboembolia pulmonar aguda e fizemos algumas reflexões. A probabilidade clínica de tromboembolia pulmonar aguda em cenários de doença pulmonar obstrutiva crônica é usualmente intermediária, o mapeamento de ventilação e perfusão pulmonares é predominantemente de probabilidade intermediária e os algoritmos de conduta os deveriam assim considerar.; Pulmonary thromboembolism and exacerbation of chronic obstructive pulmonary disease are common conditions. Chronic obstructive pulmonary disease is a clinical risk factor for pulmonary thromboembolism. The presentation of acute pulmonary thromboembolism and acute exacerbation of chronic obstructive pulmonary disease often mimic each other so closely that they cannot be distinguished clinically. The structural abnormalities of the lungs in chronic obstructive pulmonary disease make also difficult to interpret the results of noninvasive tests like ventilation-perfusion lung scans. Therefore...

Tumour necrosis factor (TNF)-α has been found to be increased in malnourished chronic obstructive pulmonary disease (COPD) patients; however, the main cause of this phenomenon remains undetermined. In normal subjects, TNF-α production may be induced by dietary energy deprivation. The aim of this study was to investigate if stable COPD patients present alterations of inflammatory mediators after 48 h of dietary energy restriction. Fourteen COPD patients were admitted to the hospital while receiving an experimental diet with an energy content of approximately one-third of their energy needs. Clinical evaluation, nutritional assessment and serum levels of interleukin (IL)-6, TNF-α and C-reactive protein, and secretion of TNF-α by peripheral blood monocytes were assessed on admission and after the experimental diet. For reference values of the laboratory parameters, blood was collected from 10 healthy, elderly subjects. COPD patients showed significantly higher serum concentrations of IL-6 than control subjects, however, the experimental diet was not associated with statistically significant changes in the inflammatory mediators. The findings of this study, although preliminary because of the limited degree and duration of the energy restriction...

BACKGROUND Chronic obstructive pulmonary disease is a major inflammatory disease of the airways and an enormous therapeutic challenge. Within the spectrum of chronic obstructive pulmonary disease, pulmonary emphysema is characterized by the destruction of the alveolar walls with an increase in the air spaces distal to the terminal bronchioles but without significant pulmonary fibrosis. Therapeutic options are limited and palliative since they are unable to promote morphological and functional regeneration of the alveolar tissue. In this context, new therapeutic approaches, such as cell therapy with adult stem cells, are being evaluated.OBJECTIVE This article aims to describe the follow-up of up to 3 years after the beginning of a phase I clinical trial and discuss the spirometry parameters achieved by patients with advanced pulmonary emphysema treated with bone marrow mononuclear cells.METHODS Four patients with advanced pulmonary emphysema were submitted to autologous infusion of bone marrow mononuclear cells. Follow-ups were performed by spirometry up to 3 years after the procedure.RESULTS The results showed that autologous cell therapy in patients having chronic obstructive pulmonary disease is a safe procedure and free of adverse effects. There was an improvement in laboratory parameters (spirometry) and a slowing down in the process of pathological degeneration. Also...

Objective: To evaluate the lung function and clinical outcome in severe chronic obstructive pulmonary disease in patients undergoing off-pump coronary artery bypass grafting with left internal thoracic artery graft, comparing the pleural drain insertion in the intercostal versus subxyphoid region. Methods: A randomized controlled trial. Chronic obstructive pulmonary disease patients were randomized into two groups according pleural drain site: II group (n=27) - pleural drain in intercostal space; SI group (n=29) - pleural drain in the subxyphoid region. Spirometry values (Forced Vital Capacity - and Forced expiratory volume in 1 second) were obtained on preoperative and 1, 3 and 5 postoperative days. Chest x-ray from preoperative until postoperative day 5 (POD5) was performed for monitoring respiratory events, such as atelectasis and pleural effusion. Pulmonary shunt fraction and pain score was evaluate preoperatively and on postoperative day 1. Results: In both groups there was a significant decrease of the spirometry values (Forced Vital Capacity and Forced expiratory volume in 1 second) until POD5 (P<0.05). However, when compared, SI group presented less decrease in these parameters (P<0.05). Pulmonary shunt fraction was significantly lower in SI group (P<0.05). Respiratory events...

INTRODUCTION: Chronic obstructive pulmonary disease is characterized by progressive and partially reversible obstruction of pulmonary airflow. AIM: To characterize swallowing in patients with chronic obstructive pulmonary disease and correlate the findings with the degree chronic obstructive pulmonary disease, heart and respiratory rate, oxygen saturation, and smoking. METHOD: We conducted a prospective cohort study of 19 patients (12 men and 7 women; age range, 50-85 years) with confirmed medical diagnosis of chronic obstructive pulmonary disease. This study was performed in 2 stages (clinical evaluation and functional assessment using nasolaryngofibroscopy) on the same day. During both stages, vital signs were checked by medical personnel. RESULTS: Clinical evaluation of swallowing in all patients showed the clinical signs of cough. The findings of nasolaryngofibroscopy highlighted subsequent intraoral escape in 5 patients (26.5%). No patient had tracheal aspiration. There was no association of subsequent intraoral escape with degree of chronic obstructive pulmonary disease, heart and respiratory rate, oxygen saturation, or smoking. CONCLUSION: In patients with chronic obstructive pulmonary disease, there was a prevalence of oral dysphagia upon swallowing and nasolaryngofibroscopy highlighted the finding of subsequent intraoral escape. There was no correlation between intraoral escape and the degree of chronic obstructive pulmonary disease...

Chronic obstructive pulmonary disease is a highly prevalent, complex disease, usually caused by cigarette smoke. It causes serious morbidity and mortality and costs the global community billions of dollars per year. While chronic inflammation, extracellular matrix destruction and increased airway epithelial cell apoptosis are reported in chronic obstructive pulmonary disease, the understanding of the basic pathogenesis of the disease is limited and there are no effective treatments. We hypothesized that the accumulation of apoptotic airway epithelial cells chronic obstructive pulmonary disease in could be due to defective phagocytic clearance by alveolar macrophages. There have been no previous studies of the phagocytic capacity of alveolar macrophages in chronic obstructive pulmonary disease using physiologically relevant apoptotic airway epithelial cells as phagocytic targets. We developed a phagocytosis assay whereby cultured 16HBE airway epithelial cells were induced to apoptosis with ultraviolet radiation and stained with mitotracker green. Alveolar macrophages from bronchoalveolar lavage from eight control and six chronic obstructive pulmonary disease subjects were analysed following 1.5 h incubation with apoptotic airway epithelial cells...

In chronic obstructive pulmonary disease (COPD/emphysema) we have shown a reduced ability of lung and alveolar (AM) macrophages to phagocytose apoptotic cells (defective ‘efferocytosis’), associated with evidence of secondary cellular necrosis and a resultant inflammatory response in the airway. It is unknown whether this defect is present in cancer (no COPD) and if so, whether this results from soluble mediators produced by cancer cells. We investigated efferocytosis in AM (26 controls, 15 healthy smokers, 37 COPD, 20 COPD+ non small cell lung cancer (NSCLC) and 8 patients with NSCLC without COPD) and tumor and tumor-free lung tissue macrophages (21 NSCLC with/13 without COPD). To investigate the effects of soluble mediators produced by lung cancer cells we then treated AM or U937 macrophages with cancer cell line supernatant and assessed their efferocytosis ability. We qualitatively identified Arachidonic Acid (AA) metabolites in cancer cells by LC-ESI-MSMS, and assessed the effects of COX inhibition (using indomethacin) on efferocytosis. Decreased efferocytosis was noted in all cancer/COPD groups in all compartments. Conditioned media from cancer cell cultures decreased the efferocytosis ability of both AM and U937 macrophages with the most pronounced effects occurring with supernatant from SCLC (an aggressive lung cancer type). AA metabolites identified in cancer cells included PGE2. The inhibitory effect of PGE2 on efferocytosis...

Objective: To explore service availability and accessibility for people with advanced chronic obstructive pulmonary disease (COPD) and their carers and strategies for improvement, including the potential role of a COPD care co-ordinator in ensuring best-practice care in the Australian context. Methods: This qualitative study used focus groups and interviews with health professionals, carers and consumers to explore gaps and restrictions in services, barriers to access and the functioning of services. Data were analysed deductively. Results: Key themes arising from the data included difficulties around access to care, lack of continuity of care, poor care co-ordination, the need for active disease management as well as supportive care, and poor communication. A COPD care co-ordinator was suggested as an effective strategy for ensuring best-practice care. Conclusions: People with advanced COPD often have difficulty navigating the acute, primary and community care systems to deal with the multiple services that they may require. Lack of communication between health professionals and services is frequently a significant issue. A COPD care co-ordinator, encompassing advanced nursing skills, could ensure that care is centred on the needs of the person and their carer and that they receive continuing...

Sleep hypoventilation (SH) may be important in the development of hypercapnic respiratory failure in chronic obstructive pulmonary disease (COPD). The prevalence of SH, associated factors, and overnight changes in waking arterial blood gases (ABG), were assessed in 54 stable hypercapnic COPD patients without concomitant sleep apnoea or morbid obesity. Lung function assessment, anthropomorphic measurements, and polysomnography with ABG measurement before and after sleep were conducted in all patients. Transcutaneous carbon dioxide tension (Pt,CO2) was measured in sleep, using simultaneous arterial carbon dioxide tension (Pa,CO2) for in vivo calibration and to correct for drift in the sensor. Of the patients, 43% spent > or = 20% of sleep time with Pt,CO2 > 1.33 kPa (10 mmHg) above waking baseline. Severity of SH was best predicted by a combination of baseline Pa,CO2, body mass index and per cent rapid-eye movement (REM) sleep. REM-related hypoventilation correlated significantly with severity of inspiratory flow limitation in REM, and with apnoea/hypopnoea index. Pa,CO2 increased mean+/-SD 0.70+/-0.65 kPa (5.29+/-4.92 mmHg) from night to morning, and this change was highly significant. The change in Pa,CO2 was strongly correlated with severity of SH. Sleep hypoventilation is common in hypercapnic chronic obstructive pulmonary disease...

BACKGROUND: oropharyngeal dysphagia in patients with chronic obstructive pulmonary disease. PURPOSE: patients with Chronic Obstructive Pulmonary Disease (COPD) can be vulnerable to respiratory incompetence that may lead to swallowing impairment. A systematic review was conducted to investigate the relationship between Chronic Obstructive Pulmonary Disease and oropharyngeal dysphagia. Forty-seven articles were retrieved relating to Chronic Obstructive Pulmonary Disease and dysphagia. Each article was graded using evidence-based methodology. Only 7 articles out of the 47 addressed oropharyngeal swallowing disorders in patients with Chronic Obstructive Pulmonary Disease. This review found few studies that documented the relationship between oropharyngeal swallowing disorders and Chronic Obstructive Pulmonary Disease. There were no randomized control trials. CONCLUSION: although the evidence is not strong, it appears that patients with Chronic Obstructive Pulmonary Disease are prone to oropharyngeal dysphagia during exacerbations. Future studies are needed to document the prevalence of oropharyngeal dysphagia in homogeneous groups of patients with Chronic Obstructive Pulmonary Disease, and to assess the relationship between respiration and swallowing using simultaneous measures of swallowing biomechanics and respiratory function. These investigations will lead to a better understanding of the characteristics and risk factors of developing oropharyngeal dypshagia in patients with Chronic Obstructive Pulmonary Disease.

OBJECTIVE: to assess the quality of life and burden of caregivers to Chronic Obstructive Pulmonary Disease patients on Long-Term Oxygen Therapy and to investigate the factors influencing this burden. METHOD: this is an analytical, cross-sectional study of 80 persons with Chronic Obstructive Pulmonary Disease on Long-Term Oxygen Therapy who used the specialized outpatient center of the Federal University of São Paulo, and their carers. The following instruments were used: Medical Outcomes Studies 36 (SF-36), Caregiver Burden Scale (CBS) and the Katz Index, along with socio-demographic and clinical variables. RESULTS: the most compromised scores on the carers' quality of life questionnaire were for Vitality and Mental Health. On the Caregiver Burden Scale, the domain which created the greatest burden for carers was the Environment. With the exception of Emotional Involvement, all the domains of quality of life were affected negatively by the domains of caregiver burden. CONCLUSION: it was shown that carers' quality of life was compromised and that they were overburdened with care tasks, confirming that assisting persons with Chronic Obstructive Pulmonary Disease is an important element in carers' quality of life.

OBJECTIVE: The potential influence of magnesium on exercise performance is a subject of increasing interest. Magnesium has been shown to have bronchodilatatory properties in asthma and chronic obstructive pulmonary disease patients. The aim of this study was to investigate the effects of acute magnesium IV loading on the aerobic exercise performance of stable chronic obstructive pulmonary disease patients. METHODS: Twenty male chronic obstructive pulmonary disease patients (66.2 + 8.3 years old, FEV1: 49.3+19.8%) received an IV infusion of 2 g of either magnesium sulfate or saline on two randomly assigned occasions approximately two days apart. Spirometry was performed both before and 45 minutes after the infusions. A symptom-limited incremental maximal cardiopulmonary test was performed on a cycle ergometer at approximately 100 minutes after the end of the infusion. ClinicalTrials.gov: NCT00500864 RESULTS: Magnesium infusion was associated with significant reductions in the functional residual capacity (-0.41 l) and residual volume (-0.47 l), the mean arterial blood pressure (-5.6 mmHg) and the cardiac double product (734.8 mmHg.bpm) at rest. Magnesium treatment led to significant increases in the maximal load reached (+8 w) and the respiratory exchange ratio (0.06) at peak exercise. The subgroup of patients who showed increases in the work load equal to or greater than 5 w also exhibited significantly greater improvements in inspiratory capacity (0.29 l). CONCLUSIONS: The acute IV loading of magnesium promotes a reduction in static lung hyperinflation and improves the exercise performance in stable chronic obstructive pulmonary disease patients. Improvements in respiratory mechanics appear to be responsible for the latter finding.

OBJETIVO: Estimar a prevalência e fatores associados à doença pulmonar obstrutiva crônica. MÉTODOS: Estudo transversal, de base populacional com 1.441 indivíduos de ambos os sexos e com 40 anos de idade ou mais no município de São Paulo, SP, entre 2008 e 2009. As informações foram coletadas por meio de entrevistas domiciliares e os participantes foram selecionados a partir de amostragem probabilística, estratificada por sexo e idade, e por conglomerados em dois estágios (setores censitários e domicílios). Foi realizada regressão múltipla de Poisson na análise ajustada. RESULTADOS: Dos entrevistados, 4,2% (IC95% 3,1;5,4) referiram doença pulmonar obstrutiva crônica. Após análise ajustada, identificaram-se os seguintes fatores independentemente associados ao agravo: número de cigarros fumados na vida (>; 1.500/nenhum) RP = 3,85 (IC95%: 1,87;7,94), cansar-se com facilidade (sim/não) RP = 2,61 (IC95% 1,39;4,90), idade (60 a 69 anos/50 a 59 anos) RP = 3,27 (IC95% 1,01;11,24), idade (70 anos e mais/50 a 59 anos) RP = 4,29 (IC95% 1,30;14,29), problemas de saúde nos últimos 15 dias (sim/não) RP = 1,31 (IC95% 1,02;1,77), e atividade física no tempo livre (sim/não) RP = 0,57 (IC95% 0,26;0,97). CONCLUSÕES: A prevalência da doença pulmonar obstrutiva crônica é elevada e está associada ao uso do tabaco e idade acima de 60 anos. Os problemas de saúde freqüentes e redução da atividade física no tempo livre podem ser considerados conseqüências dessa doença.; OBJETIVO: Estimar la prevalencia y factores asociados con la enfermedad pulmonar obstructiva crónica.
