Abstract Chronic Obstructive Pulmonary Disease (COPD) is a public health problem because it is a major cause of death in the world. Approximately 25% of patients with moderate disease and 35% with severe disease show a reduced fat-free mass (FFM). Thus, the objective of this study is to define the correlation between fat-free mass index (FFMI), muscle function, respiratory symptoms, number of exacerbations during the last year, and degree of airflow obstruction in patients with COPD. It is a prospective and cross-sectional study. The FFMI was below 32.7% (n=18) and the strength diminished by 56.4% (n=31). In the sample, we found a direct and significant correlation between the FFMI and the FEV1 (predicted %), (p= 0.045). When analysed by sex, men had a direct correlation between FFMI and the FEV1 (predicted %), (p=0.019), an inverse correlation between FFMI and the spirometric classification of the Global Initiative Obstructive Lung Disease (GOLD) (p=0.008), and between the muscular function and the symptoms (p=0.03). In women, no significant correlation was found. In conclusion, the conditions in mass and muscular function were correlated with clinical variables and pulmonary function in men. We did not find a correlation between corporal composition and the number of exacerbations.

Objective: To define the correlation between the Fat Free Mass Index (FFMI), the muscle function, degree of airflow obstruction, the respiratory symptoms and the number of exacerbations during the last year in patients with Chronic Obstructive Pulmonary Disease (COPD). Methods: Prospective and cross-sectional study of subjects older than 40 years with a clinical diagnosis of COPD who underwent measurement of the FFMI and muscular function to determine if these were correlated with the variables of severe COPD. Results: 55 patients Participated in the study. The FFMI was below 32.7% (n=18) and the strength diminished in 56.4% (n=31). In the sample, we found a direct and significant correlation between the FFMI and the FEV1* (predicted %), (p= 0,045). When analyzed by sex, men had a direct correlation between FFMI and the FEV1*(predicted %), (p=0,019), an inverse correlation between FFMI and the spirometric classification of the Global Initiative Obstructive Lung Disease (GOLD) (p=0,008) and between the muscular function and the symptoms (p=0, 03). In women no significant correlation was found. Conclusions: The conditions in mass and the muscular function were correlated with clinical variables and pulmonary function in men, but not in women. We did not find a correlation between corporal composition and the number of exacerbations.

Pulmonary tuberculosis (PTB) and chronic obstructive pulmonary disease (COPD) are important causes of mortality and morbidity in Malaysia. The number of tuberculosis (TB) cases in Malaysia appears to be increasing and there were 500,000 Malaysians diagnosed with COPD in 2016. A substantial number of PTB patients go on to develop post tubular airway disease. Past infection with TB has been shown to contribute to the aetiology of COPD. We conducted a one year cross-sectional study in outpatient setting involving adult subjects in Universiti Kebangsaan Malaysia Medical Centre (UKMMC) with a history of pulmonary tuberculosis three years prior to the study. We excluded subjects with bronchial asthma, COPD, interstitial lung disease and bronchiectasis. Airflow obstruction was defined as FEV1: FVC ratio <0.70. The COPD Assessment Test (CAT) questionnaire was used. Eighty-two subjects were recruited with a median age of 52.5 years (IQR 36-62). Male predominance (56.1%) with 29 (35.4%) smokers. Eighteen (22%) subjects had airflow obstruction. Six (33%) out of these subjects were smokers. Fourteen(17%) had restrictive pattern and 50 (61%) had normal spirometry results. Five subjects (22.22%) had mild obstruction, 7 (44.44%) moderate obstruction, and 6 (33.33%) had severe obstruction. There was a positive correlation between chest X-ray abnormalities and age with airflow obstruction (P<0.05). Abnormal spirometry pattern was found in 39% of subjects. Post TB-COPD incidence was 22% in those who completed TB treatment. There appeared to be an association between abnormal chest radiograph findings with airflow obstruction in subjects with history of PTB.

Introduction Chronic obstructive pulmonary disease (COPD) is expected to be the third leading cause of premature death and disability in Canada and around the world by the year 2020. The study aims to compare objective physical activity (PA) and sedentary time in a population-based sample of adults with chronic obstructive pulmonary disease (COPD) and comparison a group, and to investigate whether these behaviors differ according to COPD severity. Methods From the 2007-2013 Canadian Health Measures Survey dataset, accelerometer and pre-bronchodilator spirometry data were available for 6441 participants, aged 35 to 79. Two weighted analyses of covariance were performed with adjustments for age, sex, body mass index, accelerometer wearing time and season, work, smoking (cotinine), education level and income. A set of sensitivity analyses were carried out to examine the possible effect of COPD, and type of control group.ResultsA cross-sectional weighted analysis indicated that 14,6% of study participants had a measured airflow obstruction consistent with COPD. Time in PA (moderate-vigorous and light PA), number of steps and sedentary duration were not significantly different in participants with COPD, taken together, compared to controls. However, moderate to severe COPD participants (stages ≥2) had a significantly lower daily time spent in PA of moderate and vigorous intensity level compared to controls.ConclusionsCanadian adults with COPD with all disease severity levels combined did not perform lower daily duration of light, moderate and vigorous PA, number of steps and higher daily sedentary time than those without airflow obstruction. Both groups are extremely sedentary and have low PA duration. Thus, “move more and sit less” public health strategy could equally target adults with or without COPD.

Background: Chronic obstructive pulmonary disease (COPD) is frequently associated with exertional oxygen desaturation, which may be evaluated using the 6-minute walking test (6MWT). However, it is a time-consuming test. The 1-minute sit-to-stand test (1STST) is a simpler test, already used to evaluate the functional status. The aim of this study was to compare the 1STST to the 6MWT in the evaluation of exertional desaturation. Methods: This was a cross-sectional study including 30 stable COPD patients who performed the 6MWT and 1STST on the same day. Six-minute walking distance (6MWD), number of 1STST repetitions (1STSTr), and cardiorespiratory parameters were recorded. Results: A significant correlation was found between the 6MWD and the number of 1STSTr (r = 0.54; p = 0.002). The minimum oxygen saturation (SpO2) in both tests showed a good agreement (intraclass correlation coefficient (ICC) 0.81) and correlated strongly (r = 0.84; p < 0.001). Regarding oxygen desaturation, the total agreement between the tests was 73.3% with a fair Cohen’s kappa (κ = 0.38; p = 0.018), and 93.33% of observations were within the limits of agreement for both tests in the Bland–Altman analysis. Conclusion: The 1STST seems to be a capable tool of detecting exercise-induced oxygen desaturation in COPD. Because it is a less time- and resources-consuming test, it may be applied during the outpatient clinic consultation to regularly evaluate the exercise capacity and exertional desaturation in COPD.

BACKGROUND: Targeted spirometry screening for chronic obstructive pulmonary disease (COPD) has been studied in primary care and community settings. Limitations regarding availability and quality of testing remain. A targeted spirometry screening program was implemented within a presurgical screening (PSS) clinic to detect undiagnosed airways disease and identify patients with COPD/asthma in need of treatment optimization.OBJECTIVE: The present quality assurance study evaluated airflow obstruction detection rates and examined characteristics of patients identified through the targeted screening program.METHODS: The targeted spirometry screening program was implemented within the PSS clinic of a tertiary care university hospital. Current or ex-smokers with respiratory symptoms and patients with a history of COPD or asthma underwent prebronchodilator spirometry. History of airways disease and smoking status were obtained during the PSS assessment and confirmed through chart reviews.RESULTS: After exclusions, the study sample included 449 current or ex-smokers. Abnormal spirometry results were found in 184 (41%) patients: 73 (16%) had mild, 93 (21%) had moderate and 18 (4%) had severe or very severe airflow obstruction. One hundred eighteen (26%) new cases of airflow obstruction suggestive of COPD were detected. One-half of these new cases had moderate or severe airflow obstruction. Only 34% of patients with abnormal spirometry results had reported a previous diagnosis of COPD. More than one-half of patients with abnormal spirometry results were current smokers.CONCLUSIONS: Undiagnosed airflow obstruction was detected in a significant number of smokers and ex-smokers through a targeted screening program within a PSS clinic. These patients can be referred for early intervention and secondary preventive strategies.

Background: Six minute walk test (6MWT) is a sub-maximal exercise test, used as a clinical indicator of the functional capacity, in patients with cardiopulmonary diseases. It is simple, objective and reproducible test. The present study was designed to assess correlation of six minute walk test with spirometry parameters, in patients with chronic obstructive pulmonary disease.Methods: In this cross sectional study, fifty patients diagnosed with chronic obstructive pulmonary disease (GOLD criteria) coming to tertiary center were recruited according to inclusion and exclusion criteria. All patients underwent spirometric measurement. Spirometric indices including FEV1, FVC, FEV1/FVC and MVV were tested using computerized spirometer. 6MWT was performed following American Thoracic Society (ATS) guidelines. Percent (%) predicted 6MWD was calculated. Correlation between spirometry and 6MWT was assessed.Results: It was found that correlation between 6MWT and spirometry is statistically significant. There is significant strong positive correlation between percent predicted 6MWD and FEV1 (r=0.850 and p= <0.001), whereas there is significant moderate correlation between percent predicted 6MWD and FVC (r=0.554 and p= <0.001), FEV1/FVC (r=0.509 and p= <0.001) and MVV (r=0.615 and p= <0.001).Conclusions: In chronic obstructive pulmonary disease, percent predicted 6mwd significantly correlated with the spirometry parameters (FEV1, FVC, FEV1/FVC, and MVV). 6MWD decreases as there is decline in the pulmonary function. 6MWT can be a useful replacement of spirometry in assessment of severity of COPD.
