Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) is one of the most common chronic airway diseases in the world. OBJECTIVE To predict the degree of mixed venous oxygen saturation (SvO2) impairment in patients with COPD by modeling using clinical-CT radiomics data and to provide reference for clinical decision-making. METHODS A total of 236 patients with COPD diagnosed by CT and clinical data at Xiangyang No. 1 People's Hospital (n= 157) and Xiangyang Central Hospital (n= 79) from June 2018 to September 2021 were retrospectively analyzed. The patients were divided into group A (SvO⩾2 62%, N= 107) and group B (SvO<2 62%, N= 129). We set up training set and test set at a ratio of 7/3 and time cutoff spot; In training set, Logistic regression was conducted to analyze the differences in general data (e.g. height, weight, systolic blood pressure), laboratory indicators (e.g. arterial oxygen saturation and pulmonary artery systolic pressure), and CT radiomics (radscore generated using chest CT texture parameters from 3D slicer software and LASSO regression) between these two groups. Further the risk factors screened by the above method were used to establish models for predicting the degree of hypoxia in COPD, conduct verification in test set and create a nomogram. RESULTS Univariate analysis demonstrated that age, smoking history, drinking history, systemic systolic pressure, digestive symptoms, right ventricular diameter (RV), mean systolic pulmonary artery pressure (sPAP), cardiac index (CI), pulmonary vascular resistance (PVR), 6-min walking distance (6MWD), WHO functional classification of pulmonary hypertension (WHOPHFC), the ratio of forced expiratory volume in the first second to the forced vital capacity (FEV1%), and radscore in group B were all significantly different from those in group A (P< 0.05). Multivariate regression demonstrated that age, smoking history, digestive symptoms, 6MWD, and radscore were independent risk factors for SvO2 impairment. The combined model established based on the abovementioned indicators exhibited a good prediction effect [AUC: 0.903; 95%CI (0.858-0.937)], higher than the general clinical model [AUC: 0.760; 95%CI (0.701-0.813), P< 0.05] and laboratory examination-radiomics model [AUC: 0.868; 95%CI (0.818-0.908), P= 0.012]. The newly created nomogram may be helpful for clinical decision-making and benefit COPD patients. CONCLUSION SvO2 is an important indicator of hypoxia in COPD, and it is highly related to age, 6MWD, and radscore. The combined model is helpful for early identification of SvO2 impairment and adjustment of COPD treatment strategies.

Abstract
OBJECTIVES Clinical outcome assessment (COA) developers must ensure that measures assess aspects of health that are meaningful to the target patient population. Although the methodology for doing this is well understood for certain COAs, such as patient-reported outcome measures, there are fewer examples of this practice in the development of digital endpoints using mobile sensor technology such as physical activity monitors. This study explored the utility of social media data, specifically, posts on online health boards, in understanding meaningful aspects of health related to physical activity in 3 different chronic diseases: fibromyalgia, chronic obstructive pulmonary disease, and chronic heart failure. METHODS We used machine learning and manual coding to summarize the content of posts extracted from 4 online health boards. Where available, patient age and sex were retrieved from post content or user profiles. We utilized analytical approaches to assess the robustness of findings to differences in the characteristics of online samples compared to the true patient population. Finally, we assessed concept saturation by measuring the convergence of autocorrelations. RESULTS We identify a number of aspects of health described as important by patients in our samples, and summarize these into concepts for measurement. For chronic heart failure, these included purposeful walking duration and speed, fatigue, difficulty going upstairs, standing, and aspects of physical exercise. Overall and age-adjusted results did not differ considerably for each disease group. CONCLUSIONS This study illustrates the potential of performing concept elicitation research using social media data, which may provide valuable insight to inform COA development.

Abstract
OBJECTIVES Chronic obstructive pulmonary disease (COPD) is characterized by persistent airflow limitation and high symptom burden that interferes with physical activity and results in a vicious cycle of inactivity and symptom worsening. The aim of this multicenter, observational study was to determine the prevalence and severity of morning, daytime and night-time symptoms as well as patterns of physical activity levels (PALs) and their interrelation in Belgian COPD patients, enrolled in the multinational SPACE study (NCT03031769). METHODS Socio-demographic, socio-economic and disease characteristics data were collected from patients' medical records as part of a routine visit to their primary care practice or pulmonologist. Dedicated questionnaires were used to evaluate respiratory symptoms for each part of the day. PAL was assessed by means of self- and interview-reported tools, and physician's judgment. Patients were also classified according to GOLD recommendations 2013 and 2017. RESULTS Overall, 102 Belgian patients participated in the study (mean age 67 years, 60.8% males). Over 85% of patients experienced respiratory symptoms throughout the day and about one-third were considered as 'active' (PAL ≥150 minutes/week). Physician-assessed PALs were higher than self-reported PALs, categorizing fewer patients as 'inactive' (17.6% versus 42.2%, respectively). PALs and symptoms were weakly interrelated. Inactive patients were present in all GOLD classification groups. CONCLUSION Stable Belgian COPD patients enrolled in the SPACE study presented 24-hour respiratory symptoms and insufficient PALs. Physicians tended to overestimate patients' physical activity. Inactive patients were present across all GOLD classification groups. New approaches are deemed necessary to objectively identify and activate sedentary patients.

Abstract
“Exercise starts and ends in the brain”: this was the title of a review article authored by Dr. Bengt Kayser back in 2003. In this piece of work, the author highlights that pioneer studies have primarily focused on the cardiorespiratory-muscle axis to set the human limits to whole-body exercise tolerance. In some circumstances, however, exercise cessation may not be solely attributable to these players: the central nervous system is thought to hold a relevant role as the ultimate site of exercise termination. In fact, there has been a growing interest relative to the “brain” response to exercise in chronic cardiorespiratory diseases, and its potential implication in limiting the tolerance to physical exertion in patients. To reach these overarching goals, non-invasive techniques, such as near-infrared spectroscopy and transcranial magnetic stimulation, have been successfully applied to get insights into the underlying mechanisms of exercise limitation in clinical populations. This review provides an up-to-date outline of the rationale for the “brain” as the organ limiting the tolerance to physical exertion in patients with cardiorespiratory diseases. We first outline some key methodological aspects of neuromuscular function and cerebral hemodynamics assessment in response to different exercise paradigms. We then review the most prominent studies, which explored the influence of major cardiorespiratory diseases on these outcomes. After a balanced summary of existing evidence, we finalize by detailing the rationale for investigating the “brain” contribution to exercise limitation in hitherto unexplored cardiorespiratory diseases, an endeavor that might lead to innovative lines of applied physiological research.

Abstract
A gap exists between guidelines and real-world clinical practice for the management and treatment of chronic obstructive pulmonary disease (COPD). Although this has narrowed in the last decade, there is room for improvement in detection rates, treatment choices and disease monitoring. In practical terms, primary care practitioners need to become aware of the huge impact of COPD on patients, have non-judgemental views of smoking and of COPD as a chronic disease, use a holistic consultation approach and actively motivate patients to adhere to treatment.This article is based on discussions at a virtual meeting of leading Nordic experts in COPD (the authors) who were developing an educational programme for COPD primary care in the Nordic region. The article aims to describe the diagnosis and lifelong management cycle of COPD, with a strong focus on providing a hands-on, practical approach for medical professionals to optimise patient outcomes in COPD primary care.

FRONTIERS IN REHABILITATION SCIENCES 2021; 2:729190. [PMID: 36188865 PMCID: PMC9397839 DOI: 10.3389/fresc.2021.729190] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/22/2021] [Accepted: 09/24/2021] [Indexed: 11/18/2022]
Abstract
Background: The COVID-19 pandemic brought numerous challenges, namely in routine assessment of people with chronic obstructive pulmonary disease (COPD). The COPD Assessment Test (CAT), the Functional Assessment of Chronic Illness-Fatigue-Subscale (FACIT-FS) and the St. George's respiratory questionnaire (SGRQ) are important patient-reported outcome measures used to assess people with COPD, but its face-to-face application has been compromised. The telephone interview offers a simple and effective alternative, yet uncertainty regarding its equivalence remains. This study aimed to establish the reliability and validity of the CAT, the FACIT-FS and the SGRQ administered by telephone interview in people with COPD. Methods: Data from an observational prospective study including people with COPD were analyzed. Participants answered to the CAT, FACIT-FS and SGRQ questionnaires in person and by telephone, with a maximum interval of 48-h. Participants were randomly selected to answer first to the in-person questionnaire followed by telephone or vice versa. Reliability measures included internal consistency with Cronbach's alpha, test-retest reliability with the intraclass correlation coefficient (ICC2,1), test-retest measurement error with the standard error of measurement (SEM) and agreement with the Bland and Altman 95% limits of agreement. Validity was assessed with the Spearman correlation (rho). Results: Fifty-five people with COPD (44 men; 68.1 ± 7.9 years; FEV1: 59.1 ± 20.3% predicted) were included. Similar internal consistency was observed between in person vs. telephone interview for the CAT (0.82 vs. 0.84), the FACIT-FS (0.83 vs. 0.84) and the SGRQ (0.92 vs. 0.93). Test-retest reliability was excellent, with an ICC2,1 of 0.77 (95% CI: 0.65; 0.86), 0.86 (95% CI: 0.77; 0.92) and 0.94 (95% CI: 0.90; 0.96) for the CAT, FACIT-FS and SGRQ total scores, respectively. The SEM showed a low level of associated measurement error and the Bland and Altman plots illustrated a good level of agreement between both modes of administration, with no evidence of systematic bias. Robust positive correlations (rho 0.87–0.94, p < 0.001) were found for the CAT, FACIT-FS and SGRQ total scores applied by both methods. Conclusion: The telephonic administration of the CAT, the FACIT-FS and the SGRQ are a valid and reliable alternative approach to in person interviews for monitoring symptoms and health-related quality of life in people with COPD. The telephone might be an important add-on for personalized assessment and management of COPD thru remote monitoring.

Abstract
Objective This study assessed the characteristics and the relationship between symptoms in any part of the 24-hour (24-h) day, physical activity level (PAL), and other clinical and functional outcomes in stable COPD patients. Patients and Methods Out of the 2162 patients enrolled in the SPACE study (The Symptoms and Physical Activity in COPD patients in Europe, clinicaltrials.gov NCT03031769), 406 (18.8%) were recruited from Romania. Here, we present the Romanian cohort results. Eligible patients were adults with age at least 40 years, confirmed diagnosis of stable COPD, current or former smokers with a smoking history of minimum 10 pack-years. The 24-h respiratory symptoms were assessed using Early Morning Symptoms of COPD Instrument (EMSCI), Evaluating Respiratory Symptoms in COPD (E-RS™: COPD) and Nighttime Symptoms of COPD Instrument (NiSCI). During clinical interview, patients self-evaluated PAL through Exercise as Vital Sign (EVS) and Yale Physical Activity Survey (YPAS). Physicians assessed PAL through their clinical judgment. Results For each combination of 2 between the early morning (EM), daytime (DT) and night-time (NT) symptoms of the 24-h day, there was a significant association (p < 0.001 for each). All symptoms significantly correlated with exacerbation history (p < 0.001 for EM and NT, p=0.002 for DT), and number of severe exacerbations (p < 0.001 for DT, p=0.001 for EM and p=0.026 for NT, respectively). The 24-h symptoms correlated negatively and significantly with PAL (p < 0.001), irrespective of the assessment used. Self-reported PAL negatively correlated with dyspnea, symptom burden, severity of disease and number of exacerbations (p < 0.001). Patients spent an average (standard deviation) of 25.8 (21.0) hours/week performing physical activity. Physicians overestimated their patients' daily PAL. Conclusion A negative and significant correlation between the 24-h day symptoms and PAL was identified in stable COPD patients. Physicians need to routinely assess PAL using adequate tools and start educating inactive COPD patients to optimize their disease outcomes.

Abstract
Chronic obstructive pulmonary disease (COPD), the frequently fatal pathology of the respiratory tract, accounts for half a billion cases globally. COPD manifests via chronic inflammatory response to irritants, frequently to tobacco smoke. The progression of COPD from early onset to advanced disease leads to the loss of the alveolar wall, pulmonary hypertension, and fibrosis of the respiratory epithelium. Here, we focus on the epidemiology, progression, and biomarkers of COPD with a particular connection to lung cancer. Dissecting the cellular and molecular players in the progression of the disease, we aim to shed light on the role of smoking, which is responsible for the disease, or at least for the more severe symptoms and worse patient outcomes. We summarize the inflammatory conditions, as well as the role of EMT and fibroblasts in establishing a cancer-prone microenvironment, i.e., the soil for ‘COPD-derived’ lung cancer. We highlight that the major health problem of COPD can be alleviated via smoking cessation, early diagnosis, and abandonment of the usage of biomass fuels on a global basis.

Abstract
Reduced physical activity (PA) is an independent risk factor for lung function decline, hospitalization and mortality in chronic obstructive pulmonary disease (COPD) and affects a large proportion of patients from Europe and the United States. However, little is known of the level of PA of COPD patients in Latin America. The aim of this study was to provide information of the level of PA and its determinants in COPD patients in Latin America. This is an observational, cross-sectional study on patients with COPD in seven Latin American countries. PA level was evaluated with the short version of the International Physical Activity Questionnaire (IPAQ) and the association between PA and other variables was investigated. Complete information of PA level was obtained in 734 COPD patients consecutively recruited from specialized outpatient clinics; 448 (61%) were men, with a mean age of 69.6 years (standard deviation [SD] = 8.7) and a mean FEV1 (% predicted) = 49.1% (17.5%). In 37.9% the level of PA was low, and the average sitting time was 36.1 h per week. Patients with low levels of PA were older, with higher levels of dyspnea and higher CAT scores. Additionally, we found that patients with low level of PA presented more symptoms during the day. Low levels of PA have been observed in a large proportion of COPD patients of Latin America, which is higher in women and older patients and it is related with worse functional and clinical characteristics.

Abstract
Patients with chronic obstructive pulmonary disease receive a range of treatments including but not limited to inhaled bronchodilators, inhaled and systemic corticosteroids, supplemental oxygen, and pulmonary rehabilitation. Pulmonary rehabilitation is a multidisciplinary intervention that seeks to combine patient education, exercise, and lifestyle changes into a comprehensive program. Programs 6 to 8 weeks in length have been shown to improve health, reduce dyspnea, increase exercise capacity, improve psychological well-being, and reduce healthcare utilization and hospitalization. Although the use of pulmonary rehabilitation is widely supported by the literature, controversy still exists regarding what should be included in the programs. The goal of this review was to summarize the evidence for pulmonary rehabilitation and identify the areas that hold promise in improving its utilization and effectiveness.

Abstract
Little is known about chronic obstructive pulmonary disease (COPD) patients experience with home-based health treatments, which are currently rapidly evolving. A previous randomized controlled trial investigated the use of long-term oxygen enriched high flow nasal cannula (HFNC) treatment at home. The aim of this study was to explore COPD patients' experience using home HFNC treatment. Patients in this qualitative study were included from the previous RCT. All patients used long-term oxygen therapy and HFNC, the latter as a primarily nocturnal add-on. Data were collected using semi-structured interviews focused on four themes: 'Description of daily use', 'Experienced changes', 'Treatment benefits and disadvantages' and 'User-friendliness'. The interviewer played an encouraging, non-normative neutral facilitator role in order to give the participants possibility to explain themselves as fully as possible. Participants were recruited until themes were saturated. A total of 12 patients (5 males, 7 females) and 8 relatives participated. Six themes were identified as important to patient adherence: Perceived lower work of breathing; reduced symptoms; improved quality of sleep; increased activity of daily living; feeling safe; technology use. The results increase our knowledge of patient experience of using HFNC for home treatment, which improved the patients' experience through reducing symptoms and increase the activity of daily living. Furthermore, they substantiate the necessity of perceived usefulness and ease of use as important factors for adherence to treatment.

Abstract
There is no single source of compiled data on symptoms experienced by patients with chronic obstructive pulmonary disease (COPD) when awake and active throughout the day. The aim of this systematic review was to evaluate the prevalence, variability, and burden (i.e., bothersomeness and/or intensity), and the impact of daytime COPD symptoms on other outcomes. The review also evaluated the impact of interventions and the measures/tools used to assess daytime COPD symptoms in patients. A systematic literature search was conducted using the primary search terms "COPD", "symptoms", and "daytime" in EMBASE®, MEDLINE®, MEDLINE® In-Process, and CENTRAL in 2016, followed by an additional search in 2018 to capture any new literature that was published since the last search. Fifty-six articles were included in the review. The accumulated evidence indicated that the symptomatic burden of COPD appears greatest in the morning, particularly upon waking, and that these morning symptoms have a substantial impact on patients' ability to function normally through the day; they also worsen quality of life. A wide variety of tools were used to evaluate symptoms across the studies. The literature also confirmed the importance of pharmacotherapy in the management of daytime COPD symptoms, and in helping normalize daily functioning. More research is needed to better understand how COPD symptoms impact daily functioning and to evaluate COPD symptoms at well-defined periods throughout the day, using validated and uniform measures/tools. This will help clinicians to better define patients' needs and take appropriate action.

Abstract
Exercise training as part of pulmonary rehabilitation is arguably the most effective intervention to improve tolerance to physical exertion in patients with chronic obstructive pulmonary disease (COPD). Owing to the fact that exercise training has modest effects on exertional ventilation, operating lung volumes and respiratory muscle performance, improving locomotor muscle structure and function are key targets for pulmonary rehabilitation in COPD. In the current concise review, we initially discuss whether patients’ muscles are exposed to deleterious factors. After presenting corroboratory evidence on this regard (e.g., oxidative stress, inflammation, hypoxemia, inactivity, and medications), we outline their effects on muscle macro- and micro-structure and related functional properties. We then finalize by addressing the potential beneficial consequences of different training strategies on these muscle-centered outcomes. This review provides, therefore, an up-to-date outline of the rationale for rehabilitative exercise training approaches focusing on the locomotor muscles in this patient population.

Abstract
Purpose We compared clinical characteristics of COPD patients according to symptom variability and evaluated the effect of symptom variability during the first year of enrollment on clinical outcomes of COPD. Methods We analyzed COPD patients’ data from the Korean Obstructive Lung Disease (KOLD) cohort. Symptom variability was defined based on the value of standard deviation (SD) of mMRC scores obtained every 3 months during the follow-up period of the first year. Patients were divided into 2 groups: the consistent (SD of mMRC scores =0) and variable (SD of mMRC scores >0) groups. Clinical characteristics and outcomes were compared in terms of symptom variability. Results A total of 407 patients were included in the analysis. Patient age was 67.2 years and 97.8% of the subjects were male. Initial mMRC was 1.5 and the SD of mMRC scores during the first year was 0.5. There were 137 subjects (33.7%) in the consistent group and 270 (66.3%) in the variable group. The variable group showed a lower FEV1 (P=0.019) and a higher mMRC score (P=0.001). The annual incidence of acute exacerbation of COPD (AE-COPD) tended to be higher in the variable group (P=0.078) and that of severe AE-COPD was higher in the variable group than in the consistent group (P=0.002). The variable group showed a higher proportion of annual exacerbators (P=0.001) and frequent exacerbators (P=0.017). In multivariate logistic regression analysis, the variable group was significantly associated with annual exacerbators (OR =1.963, P=0.011) and frequent exacerbators (OR =2.090, P=0.055). Conclusion COPD patients with symptom variability may have higher exacerbation risk as well as lower lung function and more severe respiratory symptoms.

Abstract
OBJECTIVE Chronic obstructive pulmonary disease (COPD) is mainly treated pharmaceutically with bronchodilators. The purpose of this study was to evaluate the clinical benefits of two-times-per-day aclidinium bromide (Acli-BID) compared with once-a-day tiotropium bromide hydrate (Tio-QD) in patients with COPD. DESIGN This study was a multicentre, open-label, randomised study. SETTING Fourcentres in Kagawa prefecture, Japan. PARTICIPANT Patients who were diagnosed to have COPD Grade 2-3 according to the Global Initiative for Chronic Obstructive Lung Disease 2015 criteria were enrolled. INTERVENTIONS Patients were randomly assigned to receive Acli-BID or Tio-QD at a 1:1 ratio, and followed for 8 weeks. Acli-BID was administered in the morning and night, and Tio-QD was administered in the night. PRIMARY AND SECONDARY OUTCOME MEASURES Primary outcome was forced expiratory volume in one second area under the curve (FEV1AUC0-3), and secondary outcomes were pulmonary function, physical activity, St George's Respiratory Questionnaire (SGRQ), modified Medical Research Council (mMRC), the 8-item Short-Form Health Survey (SF-8) and COPD exacerbations. Adverse events were evaluated during the study. RESULTS 44 patients were included in this study. FEV1AUC0-3 at week 8 was 4.62±1.43 L·hour in Acli-BID and 4.73±1.60 L·hour in Tio-QD (mean difference (MD) -0.11 L·hour; 95% CI), -1.04 to 0.83). Significant improvement was observed in activity-related subscales of SGRQ (MD -7.78; 95% CI -14.61 to -0.94) and SF-8 (MD 4.01; 95% CI 0.37 to 7.65), mMRC (MD -0.66; 95% CI -1.19 to -0.13) and rate ratio (0.52, 95% CI 0.27 to 0.99) of exacerbations in the Acli-BID compared with the Tio-QD. Acli-BID and Tio-QD significantly improved sedentary behaviour (MD -35.20 min; 95% CI -67.41 to -2.94 and MD -55.40 min; 95% CI -98.15 to -12.77) within each group, but there was no significant difference between the two groups. CONCLUSION Acli-BID as with Tio-QD could be one of the therapeutic options for patients with COPD to improve pulmonary function. Also, our results suggest that intervention with bronchodilators enhanced physical activity in patients with COPD. TRIAL REGISTRATION NUMBER UMIN 000020020.

Importance of the relationship between symptoms and self-reported physical activity level in stable COPD based on the results from the SPACE study. Respir Res 2019; 20:89.

Abstract
Background The burden of symptoms and risk of exacerbations are the main drivers of the overall assessment of the Chronic Obstructive Pulmonary Disease (COPD) and the adequate treatment approaches per current Global Initiative for Chronic Obstructive Lung Disease (GOLD). Physical activity has emerged as both functional outcome and non-pharmacological intervention in COPD patients, despite the lack of standardized measures or guidelines in clinical practice. This study aimed to explore in more depth the 24-h respiratory symptoms, the physical activity level (PAL) and the relationship between these two determinants in stable COPD patients. Methods This was a multinational, multicenter, observational, cross-sectional study conducted in ten European countries and Israel. Dedicated questionnaires for each part of the day (morning, daytime, night) were used to assess respiratory symptoms. PAL was evaluated with self- and interview-reported tools [EVS (exercise as vital sign) and YPAS (Yale Physical Activity Survey)], and physician’s judgement. Patients were stratified in ABCD groups by 2013 and 2017 GOLD editions using the questionnaires currently recommended: modified Medical Research Council dyspnea scale and COPD Assessment Test. Results The study enrolled 2190 patients (mean age: 66.9 years; male: 70.0%; mean % predicted FEV1: 52.6; GOLD groups II-III: 84.5%; any COPD treatment: 98.9%). Most patients (> 90%) reported symptoms in any part of the 24-h day, irrespective of COPD severity. PAL evaluations showed discordant results between patients and physicians: 32.9% of patients considered themselves completely inactive, while physicians judged 11.9% patients as inactive. By YPAS, the overall study population spent an average of 21.0 h/week performing physical activity, and 68.4% of patients were identified as sedentary. In any GOLD ABCD group, the percentage of inactive patients was high. Our study found negative, weak correlations between respiratory symptoms and self-reported PAL (p < 0.001). Conclusions Despite regular treatment, the majority of stable COPD patients with moderate to severe disease experienced daily variable symptoms. Physical activity level was low in this COPD cohort, and yet overestimated by physicians. With evidence indicating the negative consequences of inactivity, its adequate screening, a more active promotion and regular assessment of physical activity are urgently needed in COPD patients for better outcomes.

Abstract
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 compare a group, and to investigate whether these behaviors differ according to COPD severity. From the 2007–2013 Canadian Health Measures Survey dataset, accelerometer and prebronchodilator 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, 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. A 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. Canadian adults with COPD with all disease severity levels combined did not show lower daily duration of light, moderate, and vigorous PA, and 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.

Abstract
Background Respiratory symptoms are increasingly recognized as an important consideration in COPD management. Understanding the links between the time(s) of day symptoms are experienced and overall symptom burden could support personalized management strategies. This real-world study aimed to establish the association between the time of day of symptoms and the burden on patients using validated patient-reported outcomes, health care resource utilization, and physician-perceived impact of COPD on patients’ lives. Materials and methods Analyses used data from four waves (2012, 2013, 2014, and 2016) of the Respiratory Disease Specific Programme: cross-sectional surveys of patients with COPD in Germany, Italy, Spain, and the UK. Patients were classified by their physicians as having symptoms in the morning (M), daytime (D), and/or nighttime (N) in the 4 weeks before entering the Disease Specific Programme. Outcomes included health care resource utilization, work productivity and activity impairment, COPD Assessment Test, EuroQol 5-dimension 3-level questionnaire with visual analog scale, and Jenkins Sleep Evaluation Questionnaire. Results In total, 8,844 patients were included, and 8,185 had evaluable time-of-day symptom data. Physicians reported that in the previous 4 weeks, 25% of patients experienced no symptoms, 16% D only, 17% M/D only, 6% D/N only, 4% M, N, or M/N only, and 32% M/D/N. In general, patients with M/D/N symptoms utilized more health care resources in the previous 12 months, had more prior exacerbations, and reported worse activity impairment, health status, and sleep than other symptom groups, whereas patients with symptoms at any time of the day utilized more resources, experienced more exacerbations, and reported worse health status than patients with no symptoms during the 4 weeks before entering the survey. Conclusion Patients experiencing morning, daytime, and nighttime symptoms experience a greater disease burden than those in other groups. An individualized approach to COPD treatment based on the timing and persistence of symptoms may improve outcomes for these patients.

Abstract
Early detection of treatment response is important in the long-term treatment and management of patients with chronic obstructive pulmonary disease (COPD). This analysis evaluated whether early improvement in symptoms, recorded in the first 7 or 14 days via an electronic diary (eDiary) compared with baseline, can predict clinically meaningful treatment responders at 12 weeks. CRYSTAL was a 12-week, randomized, open-label study that demonstrated the increased effectiveness of indacaterol/glycopyrronium (IND/GLY) or glycopyrronium (GLY), after a direct switch from on-going baseline therapies, in patients with symptomatic COPD and moderate airflow obstruction. The co-primary endpoints were trough forced expiratory volume in 1 second (FEV1) and transition dyspnea index (TDI) at Week 12. Patients' symptom status was recorded daily in an eDiary. Of 4,389 patients randomized, 3,936 and 3,855 reported symptoms on Days 7 and 14, respectively. Patients who reported an early decrease in symptoms on Day 7 or 14 were more likely to achieve the minimal clinically important difference of ≥100 mL in trough FEV1 or ≥ 1 point in TDI at Week 12. Using stepwise multivariate regression models we identified as best predictors of FEV1 responders the decrease in wheeze on Day 7, and nighttime symptoms and wheeze on Day 14; best predictors of TDI responders were decrease in nighttime symptoms and wheeze on Day 7, and nighttime symptoms, sputum and wheeze on Day 14. Early symptom improvement at Day 7 or 14, especially wheeze and nighttime symptoms, may identify patients with clinically important improvement in lung function and dyspnea at Week 12.

Abstract
Background Patients with chronic obstructive pulmonary disease (COPD) experience symptoms that vary over the day. Symptoms at the start of the day might influence physical activity during the rest of the day. Therefore, physical activity during the course of the day was studied in patients with low and high morning symptom scores. Methods This cross-sectional observational study included patients with moderate to very severe COPD. Morning symptoms were evaluated with the PRO-morning COPD Symptoms Questionnaire (range 0–60); the median score was used to create two groups (low and high morning symptom scores). Physical activity was examined with an accelerometer. Activity parameters during the night, morning, afternoon and evening were compared between patients with low and high morning symptom scores using independent t-tests or Mann-Whitney U tests. Results Seventy nine patients were included. Patients were aged (mean ± SD) 65.6 ± 8.8 years with a mean forced expiratory volume in 1 s of 55 ± 17%predicted. Patients with low morning symptom scores (score < 17.0) took more steps in the afternoon (p = 0.015) and morning (p = 0.030). There were no significant differences during the evening and night. Conclusion Patients with high morning symptom scores took significantly fewer steps in the morning and afternoon than those with low morning symptom scores. Prospective studies are needed to prove causality between morning symptoms and physical activity during different parts of the day.

Abstract
Objectives: To identify if pulmonary rehabilitation can achieve a clinically significant alleviation in the level of depression among chronic obstructive pulmonary disease (COPD) patients older than 70 years. Methods: We conducted a retrospective secondary analysis of the patients’ electronic records from a major pulmonary rehabilitation center in Cleveland, OH, United States between 2010 and 2014. Profiles of 105 participants who had completed more than 6 pulmonary rehabilitation sessions and were older than 70 years at the time of enrollment in the program were included. The Beck Depression Inventory scores at the baseline and the end of the pulmonary rehabilitation sessions were compared. Results: There was a statistically and clinically significant reduction in mean scores of depression from the baseline to the end of pulmonary rehabilitation: mean± SD: 104±5.6; p=0.00. The mean±SD depression score at the end was 9±4.3 compared with the baseline 17±7.8. Seventy-seven (73%) participants showed clinically significant improvement in depression; however, 20 participants (27%) had no clinically significant improvement, and 8 (8%) had worse depression at the end of pulmonary rehabilitation. Participants with higher depression scores at the baseline were 1.3 times more likely to achieve clinically significant alleviation in depression at the end of rehabilitation (odds ratio = 1.3, p=0.00). Conclusion: Pulmonary rehabilitation induced clinically significant alleviation in depression among participants with COPD aged over 70 years.

Abstract
AIMS The aim of this study was to explore the relationship between leisure-time physical inactivity and long-term sickness absence in a representative sample of individuals aged 16-54 years, within the labour market and in good health. It was hypothesised that physically inactive individuals have a higher risk of long-term sickness absence and longer duration of sickness absence. METHODS The study population was identified from the National Health and Morbidity Survey, 2010. Weekly data on long-term sickness absence were obtained from the National Register on Social Transfer Payments (the DREAM registry). The association of incidence and duration of long-term sickness absence with physical inactivity was explored using logistic and Poisson regression. Data were fitted to models with levels of physical activity, demographic, social and lifestyle characteristics as independent variables. A combined hurdle model was used to estimate the difference in mean number of absence weeks. RESULTS Logistic regression showed that physically inactive individuals had a 27% higher incidence of long-term sickness absence compared with physically active individuals. The Poisson regression showed that long-term sickness absence was only slightly shorter (1 week less) for moderately active individuals compared with inactive individuals. The hurdle model estimated longer absence periods for inactive individuals (additional 2.5 weeks) in comparison with moderately and highly active individuals. CONCLUSIONS The study showed that physically inactive individuals have a higher incidence of long-term absence and that physically inactive individuals have longer periods with sickness absence than moderately and highly active individuals. When adjustments for social and health behaviour were included, the estimated associations became statistically insignificant.

Abstract
PURPOSE The morning is the most bothersome period for COPD patients. Morning symptom severities in different Global Initiative for Chronic Obstructive Lung Disease (GOLD) stages are not well studied. Furthermore, factors that are associated with morning symptoms, especially the associations with objectively measured physical activity, are also not well described. MATERIALS AND METHODS The aim of this cross-sectional observational study was to assess morning symptom severity in GOLD A, B, C and D patients, according to the definitions of the GOLD 2015 statement. Morning symptoms were assessed with the PRO-Morning COPD Symptoms Questionnaire. Differences in morning symptom severity between different COPD stages were assessed with a one-way analysis of variance followed by post hoc analyses. The association between dyspnea severity (assessed with the modified Medical Research Council scale), health status, airflow limitation, lung hyperinflation, anxiety and depression, inflammatory parameters, exacerbations, objectively measured physical activity parameters retrieved from accelerometry and morning symptom severity was evaluated using linear regression analysis. RESULTS Eighty patients were included (aged 65.6±8.7 years, forced expiratory volume in 1 second [FEV1] % predicted 55.1±16.9). Mean (±SD) morning symptom score was 19.7 (±11.7). Morning symptom severity was significantly different between COPD stages: mean (±SD) score in GOLD A was 9.7 (±7.2), in GOLD B 19.8 (±10.7), in GOLD C 8.6 (±9.3) and in GOLD D 23.8 (±11.2) (p<0.001). Lower health status, more symptoms, increased anxiety and depression, less physical activity (all p<0.001) and lower FEV1 (p=0.03) were associated with an increased morning symptom severity. CONCLUSION Patients with overall more symptomatic COPD have significant higher morning symptom scores. Morning symptom severity was associated with important clinical outcomes: lower health status, more symptoms, increased anxiety and depression, fewer steps a day, less time in moderate and vigorous physical activity with bouts of at least 10 minutes and lower FEV1. The data suggest that morning symptoms should be carefully assessed in addition to assessment by general COPD-specific questionnaires, especially in those with more symptomatic COPD. More research is needed on potential therapies to improve morning symptoms; this study shows potential targets for intervention.

Abstract
Chronic obstructive pulmonary disease (COPD) imposes a substantial burden on individuals with the disease, which can include a range of symptoms (breathlessness, cough, sputum production, wheeze, chest tightness) of varying severities. We present an overview of the biomedical literature describing reported relationships between COPD symptoms and disease burden in terms of quality of life, health status, daily activities, physical activity, sleep, comorbid anxiety, and depression, as well as risk of exacerbations and disease prognosis. In addition, the substantial variability of COPD symptoms encountered (morning, daytime, and nighttime) is addressed and their implications for disease burden considered. The findings from this narrative review, which mainly focuses on real-world and observational studies, demonstrate the impact of COPD symptoms on the burden of disease and that improved recognition and understanding of their impact is central to alleviating this burden.

Abstract
INTRODUCTION Chronic obstructive pulmonary disease (COPD) patients experience the morning as the worst period of the day. Nevertheless, morning symptoms are not mentioned in COPD guidelines. Areas covered: Different topics on morning symptoms are covered in this review to underline their importance: occurrence, tools for assessment and therapies to limit morning symptoms. Expert commentary: Morning symptoms are common and have a negative influence on a patient's life. Pharmacotherapy seems to be effective in decreasing morning symptoms. A validated tool to assess morning symptoms is lacking. Therefore, more research should focus on assessing morning symptoms with a validated tool to further prove the effect of (pharmaco-) therapy. This will hopefully result in inclusion of morning symptoms in future guidelines.
