Objective: To evaluate the prevalence of sarcopenia in COPD patients, as well as to determine whether sarcopenia correlates with the severity and prognosis of COPD. Methods: A cross-sectional study with COPD patients followed at the pulmonary outpatient clinic of our institution. The patients underwent dual-energy X-ray absorptiometry. The diagnosis of sarcopenia was made on the basis of the skeletal muscle index, defined as appendicular lean mass/height2 only for low-weight subjects and adjusted for fat mass in normal/overweight subjects. Disease severity (COPD stage) was evaluated with the Global Initiative for Chronic Obstructive Lung Disease (GOLD) criteria. The degree of obstruction and prognosis were determined by the Body mass index, airflow Obstruction, Dyspnea, and Exercise capacity (BODE) index. Results: We recruited 91 patients (50 females), with a mean age of 67.4 ± 8.7 years and a mean BMI of 25.8 ± 6.1 kg/m2. Sarcopenia was observed in 36 (39.6%) of the patients, with no differences related to gender, age, or smoking status. Sarcopenia was not associated with the GOLD stage or with FEV1 (used as an indicator of the degree of obstruction). The BMI, percentage of body fat, and total lean mass were lower in the patients with sarcopenia than in those without (p < 0.001). Sarcopenia was more prevalent among the patients in BODE quartile 3 or 4 than among those in BODE quartile 1 or 2 (p = 0.009). The multivariate analysis showed that the BODE quartile was significantly associated with sarcopenia, regardless of age, gender, smoking status, and GOLD stage. Conclusions: In COPD patients, sarcopenia appears to be associated with unfavorable changes in body composition and with a poor prognosis.

Socioeconomic and lifestyle factors are regarded as important influencing issues regarding a wide range of chronic diseases, including chronic obstructive pulmonary disease. This study aimed to explore the role of such factors as determinants of disease exacerbation among COPD patients. A cross-sectional study was conducted among 150 COPD patients who were referred to an outpatient respiratory care center in Qazvin, Iran, to undertake respiratory function tests from December 2017 to June 2018. Disease severity was determined by the Initiative for Chronic Obstructive Lung Disease (GOLD) index. Odds ratios were applied to find out factors associated with exacerbation. Study findings affirmed that within COPD severity groups, there were significant differences among patients in terms of educational level, smoking status, income, and occupation. Factors associated with severe COPD were found to be smoking (OR 3.6, 2.6-4.2), lower education (OR 1.4, 0.9-2.6), insufficient income (OR 2.3, 0.6-3.1), and unsupportive family (2.7, 1.5-3.6). Due to the obtained evidence about the effect of socioeconomic status on the prognosis of the disease, it is suggested that clinicians should also consider the nonclinical and social aspects associated with the disease in advancing patients' therapeutic procedures and management algorithms.

Abstract Background Chronic obstructive pulmonary disease (COPD) is a multifactorial clinical condition, characterized by chronic progressive (or worsening) respiratory symptoms, structural pulmonary abnormalities, and impaired lung function, and is often accompanied by multiple, clinically significant comorbid disorders. In 2017, the Global Initiative for Chronic Obstructive Lung Disease (GOLD) issued a new report on COPD prevention, diagnosis and management, aiming at personalizing the maintenance therapeutic approach of the stable disease, based on the patients’ symptoms and history of exacerbations (ABCD assessment approach). Our objective was to evaluate the implementation of GOLD suggestions in everyday clinical practice in Greece. Methods This was a cross-sectional observational study. Sixty-five different variables (demographics, vital sign measurements, COPD-related medical history parameters, comorbidities, vaccination data, COPD severity based on spirometry measurements, COPD stage based on the ABCD assessment approach, COPD treatments) were collected from 3615 nation-wide COPD patients (Greece). Results The mean age at the time of initial COPD diagnosis was 63.8 (± 10.2). Almost 60% of the subjects were classified into group B, while the remaining patients were falling into groups A (18%) and D (21%), and only a small minority of patients belonged to Group C, according to the ABCD assessment approach. The compliance of respiratory physicians to the GOLD 2017 therapeutic suggestions is problematic, especially when it comes to COPD patients belonging to Group A. Conclusion Our data provide valuable information regarding the demographic and medical profile of COPD patients in Greece, the domains which the revised ABCD assessment approach may show some clinical significance on, and the necessity for medical practitioners dealing with COPD patients to adhere closer to international recommendations for the proper management of the disease.

Objective. The phenomenon of pendelluft was described over five decades ago. In patients with regional variations in resistance and elastance, gas moves at the beginning of inspiration out of some alveoli into others. Gas moves in the opposite direction at the end of inspiration. The objective of this study was to apply the method of lung sounds mapping, which is known to provide regional information about gas flow, to study pendelluft in COPD patients.Methods. A 16-channel lung sound analyzer was used to collect sounds from patients with COPD (n=90) and age-matched normals (n=90). Pendelluft at the beginning of inspiration is expected to result in vesicular sounds leading the tracheal sound by a few milliseconds. Pendelluft at the end of inspiration is expected to result in vesicular sounds lagging the tracheal sound. These lead and lag times were calculated for the 14 chest wall sites.Results. The lead time was significantly longer in COPD patients:123±107 ms versus48±59 ms in controls (P<0.0001). The lag time was also significantly longer in COPD patients:269±249 ms in COPD patients versus147±124 ms in controls (P<0.0001). When normalized by the duration of the inspiration at the trachea, the lead was14±13% for COPD versus4±5% for controls (P<0.0001). The lag was28±25% for COPD versus13±12% for controls (P<0.0001). Both lead and lag correlated moderately with the GOLD stage (correlation coefficient 0.43).Conclusion. Increased lead and lag times in COPD patients are consistent with the phenomenon of pendelluft as has been observed by other methods.

Chronic obstructive pulmonary disease (COPD) claimed 3.0 million lives in 2016 and ranked 3rd among the top 10 global causes of death. Moreover, once diagnosed and discharged from the hospital, the 30-day readmission risk in COPD patients is found to be the highest among all chronic diseases. The existing diagnosis methods, such as Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2019, Body-mass index, airflow Obstruction, Dyspnea, and Exercise (BODE) index, modified Medical Research Council (mMRC), COPD assessment test (CAT), 6-minute walking distance, which are adopted currently by physicians cannot predict the potential readmission of COPD patients, especially within the 30 days after discharge from the hospital. In this paper, a statistical model was proposed to predict the readmission risk of COPD patients within 30-days by monitoring their physical activity (PA) in daily living with accelerometer-based wrist-worn wearable devices. This proposed model was based on our previously reported PA models for activity index (AI) and regularity index (RI) and it introduced a new parameter, quality of activity (QoA), which incorporates previously proposed parameters, such as AI and RI, with other activity-based indices to predict the readmission risk. Data were collected from continuous PA monitoring of 16 COPD patients after hospital discharge as test subjects and readmission prediction criteria were proposed, with a 63% sensitivity and a 37.78% positive prediction rate. Compared to other clinical assessment, diagnosis, and prevention methods, the proposed model showed significant improvement in predicting the 30-day readmission risk.

Extracellular heat shock protein 70 (eHsp70) might modulate immune responses in chronic obstructive pulmonary disease (COPD). The aim of the study was to explore eHsp70 concentration in stable COPD, its association with disease severity and smoking status as well as its diagnostic performance in COPD assessment. Plasma samples were collected from 137 COPD patients and 95 healthy individuals, and concentration of eHsp70 was assessed by commercially available enzyme-linked immunosorbent assay (ELISA) kit (Enzo Life Science, Farmingdale, NY, USA). COPD patients were subdivided regarding airflow obstruction severity and symptoms severity according to the Global Initiative for COPD (GOLD) guidelines. eHsp70 concentration increased in COPD patients when compared to controls and increased with the severity of airflow limitation as well as symptoms burden and exacerbation history. eHsp70 concentration did not differ among COPD patients based on smoking status, yet it increased in healthy smokers compared to healthy nonsmokers. In addition, eHsp70 negatively correlated with lung function parameters forced expiratory volume in one second (FEV1) and FEV1/ forced vital capacity (FVC), and positively with COPD multicomponent indices BODCAT (BMI, airflow obstruction, dyspnea, CAT score), BODEx (BMI, airflow obstruction, dyspnea, previous exacerbations), CODEx (Charlson’s comorbidity index, airflow obstruction, dyspnea, previous exacerbations) and DOSE (dyspnea, airflow obstruction, smoking status, previous exacerbations) With great predictive value (OR = 7.63) obtained from univariate logistic regression, eHsp70 correctly classified 76% of cases. eHsp70 is associated with COPD prediction and disease severity and might have the potential for becoming an additional biomarker in COPD assessment.

The Global initiative for Chronic Obstructive Lung Disease (GOLD) staging has widely used in the stratification of the severity of COPD, while BODE (body mass index, airflow obstruction, dyspnea, and exercise capacity) index was proven superior to FEV1 in predicting mortality, exacerbation and disease severity in patients with COPD. Clinical COPD Questionnaire (CCQ), a questionnaire with ten items categorized into three domains (symptoms, functional state and mental state) was developed to measure health status of COPD patients. However, little is known about the relationship between CCQ score and BODE index. We performed a prospective study with the inclusion of 89 patients who were clinically stable after a 6-week-therapy for COPD symptoms comparing their health status assessed by CCQ, BODE index and GOLD staging. We found that the total CCQ score was correlated with BODE score (P<0.001) and GOLD staging (P<0.001); of three CCQ domains, the functional status correlated the most with BODE index (rS=0.670) and GOLD staging (rS=0.531), followed by symptoms (rS=0.482;rS=0.346, respectively), and mental status (rS=0.340;rS=0.236, respectively). Our data suggest that CCQ is a reliable and convenient alternative tool to evaluate the severity of COPD.

Abstract: Background: The significant reason for anguish as well as incapacity is chronic obstructive pulmonary disease (COPD). Activities of daily living might be relentlessly curbed among patients with COPD and appraisal needs evaluation regarding influence of infirmity and detriments on day-to-day living. The primary objective was to know the daily activity associated quality of life in COPD adults. The secondary objective was to analyze demographical profile, such as gender and age of COPD subjects as well as evaluate the physical activity related breathlessness in COPD patients. Methodology: This study was executed at Gulab Devi Chest Hospital. We used cross sectional study design to collect the data. For collecting the statistics of 150 subjects aged 40-60 years of either gender Saint George’s Questionnaire was liable. It included the patient’s biodata, effect of COPD on physical activities and limitations in routine work. Results: The ages of 150 COPD patients selected were between 40 and 60 years. Patients were classified into two categories on the basis of disease severity according to GOLD criteria 71 (47.3%) were with moderate severity and 79 (52.7%) were with severe severity. 113 (75.3%) patients were smokers while 37 (24.7%) patients were non-smokers. 110 (73.3%) COPD patients were active smokers in comparison 40 (26.7%) COPD patients were passive smokers. COPD patients with current smoking status were 79 (52.7%) and with past smoking status were 71 (47.3%). 19 (12.7%) COPD patients felt breathlessness while sitting and lying. 53(35.3%) COPD patients felt breathless while getting washed or dressed. 85(56.7%) COPD patients felt breathless while walking around the home. 114 (96%) COPD patients discerned breathlessness while walking up a flight of stairs. 145 (96.7%) COPD patients had breathlessness while playing sports or games. 146 (97.3%) COPD patients experienced difficulty in breathing during activities like carrying load. 88 (58.7%) COPD patients discerned breathlessness during entertainment or recreation. 88 (58.7%) COPD patients discerned breathlessness during entertainment or recreation. 7 (4.7%) COPD patients felt breathlessness while moving from bed or chair. Conclusion: As with the progression of COPD impairment in activities become worse due to breathlessness causing decline in patient’s ability making them unable to complete their task to fulfill the needs of life and ultimately become bed bound due to shortness of breath.

Breath analysis using eNose technology can be used to discriminate between asthma and COPD patients, but it remains unclear whether results are influenced by smoking status. We aim to study whether eNose can discriminate between ever- vs. never-smokers and smoking <24 vs. >24 h before the exhaled breath, and if smoking can be considered a confounder that influences eNose results. We performed a cross-sectional analysis in adults with asthma or chronic obstructive pulmonary disease (COPD), and healthy controls. Ever-smokers were defined as patients with current or past smoking habits. eNose measurements were performed by using the SpiroNose. The principal component (PC) described the eNose signals, and linear discriminant analysis determined if PCs classified ever-smokers vs. never-smokers and smoking <24 vs. >24 h. The area under the receiver–operator characteristic curve (AUC) assessed the accuracy of the models. We selected 593 ever-smokers (167 smoked <24 h before measurement) and 303 never-smokers and measured the exhaled breath profiles of discriminated ever- and never-smokers (AUC: 0.74; 95% CI: 0.66–0.81), and no cigarette consumption <24h (AUC 0.54, 95% CI: 0.43–0.65). In healthy controls, the eNose did not discriminate between ever or never-smokers (AUC 0.54; 95% CI: 0.49–0.60) and recent cigarette consumption (AUC 0.60; 95% CI: 0.50–0.69). The eNose could distinguish between ever and never-smokers in asthma and COPD patients, but not recent smokers. Recent smoking is not a confounding factor of eNose breath profiles.

Background: Worldwide, Chronic obstructive pulmonary disease (COPD) is the one of the leading cause of chronic morbidity and mortality. COPD is one of the diseases in which smoking is the common and important risk factor when it is associated with Metabolic syndrome (MetS). The individual components of MetS, i.e., obesity, dyslipidemia, fasting hyperglycaemia, and hypertension were independently associated with impairment of lung function too. The objective of this study is to find out the prevalence of metabolic syndrome among COPD patients.Methods: This was a cross-sectional study conducted in department of Respiratory Diseases and a total of 70 COPD patients were included in the study, which were enrolled for treatment from July 2016 to July 2017. The severity level in patients with COPD were determined according to GOLD (Global Initiative for Chronic Obstructive Lung Disease), 2015 guideline. International Diabetes Federation (IDF) guideline; (2005) was used in diagnosis of metabolic syndrome.Results: Seventy patients with COPD were enrolled during the study period. There were 45 males (64.2%) and 25(35.7%) females. Mean age of male patients was 58.67±9.87 years, while mean age of female patients was 57.23±10.4 years (35-87 years). Mean BMI of male was 24.33±6.64 kg/m2, while in case of female it was 30.07±6.95 kg/m2 and overall mean BMI of study population was 26.22±7.22 kg/m2. The mean   waist circumference of male was 86.91±13.31 cm while in female it was 87.18±14.51 cm. The Overall prevalence of metabolic syndrome was 31.34% and most common in GOLD stage-3 (47.06%), followed by stage-2 (40%), followed by stage-4 (25.71%) and 7.4 % in GOLD stage -1.Conclusions: The presence of metabolic syndrome is common in patients with COPD and, all COPD patients should be considered for screening for it.

<b>Background:</b> In moderate-to-severe chronic obstructive pulmonary disease (COPD) patients the 6-min walk test (6MWT) is often exhaustive and correlates with the incremental cycle cardiopulmonary exercise test (CPET). <b>Objectives:</b> The aim of this study was to assess the agreement between oxygen uptake (VO<sub>2</sub>) measured during the 6MWT by portable equipment and incremental cycle exercise in COPD patients with Global Initiative for Chronic Obstructive Lung Disease (GOLD) I–IV. <b>Methods:</b> A total of 30 patients with COPD GOLD I–IV (14 patients GOLD stage I and II and 16 patients GOLD stage III and IV) underwent a 6MWT and an incremental CPET. Breath-by-breath analysis for VO<sub>2</sub>, carbon dioxide output (VCO<sub>2</sub>), and minute ventilation (VE) were measured during each test. Blood gas analysis and lactate measurements were performed before, during, and after the test. <b>Results:</b> VO<sub>2</sub> in COPD patients GOLD stage I and II was 16.2 ± 4.2 mL/kg/min measured by 6MWT and 20.5 ± 7.0 mL/kg/min measured by CPET as compared to GOLD stage III and IV (11.2 ± 3.7 mL/kg/min measured by 6MWT and 15.5 ± 4.3 mL/kg/min measured by CPET). No significant correlation in VO<sub>2</sub> measurements could be found between both tests in COPD GOLD I and II (<i>r</i> = 0.17), whereas the VO<sub>2</sub> significantly correlated in patients with COPD stage III and IV (<i>r</i> = 0.7). <b>Conclusions:</b> A significant relationship between VO<sub>2</sub> measured by 6MWT and CPET could only be found in patients with more severe COPD but not in milder stages. 6MWT and CPET provide different VO<sub>2</sub> measurements in COPD patients. The two methods cannot be used interchangeably.
