Respir Med 2024; 231:107724. [PMID: 38971337 DOI: 10.1016/j.rmed.2024.107724] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/15/2024] [Revised: 06/11/2024] [Accepted: 06/28/2024] [Indexed: 07/08/2024]
Abstract
INTRODUCTION Very few studies have examined patterns of physical activity (PA) during a pulmonary rehabilitation (PR) program in people with COPD. AIMS To compare the patterns of PA in: 1) the week before commencing PR (pre-PR) with a week during PR (PR week); 2) PR days and non-PR days during a PR week; 3) pre-PR and the week following PR completion (post-PR). METHODS This was a multicenter, prospective cohort study. Participants attended twice weekly supervised PR for 8-12 weeks. Daily step count (primary outcome), time in light activities, time in moderate to vigorous PA (MVPA), total sedentary time and sit-to-stand (STS) transitions were measured using a thigh worn accelerometer for seven days, at each assessment time point: pre-PR, PR week and post-PR. RESULTS 29 participants, mean age (SD) 69years(7), FEV1 53%pred(16). The PR week compared to pre-PR, showed higher daily: step count (mean difference (95%CI)), 941steps(388-1494); and MVPA, 11mins(6-15), with no difference in: time in light activities, -1min(-6-5); total sedentary time, 7mins(-21-36); or STS transitions, 0(-5-6). PR days compared to non-PR days showed higher: step count, 2810steps(1706-3913); time in light activities 11mins(1-20); time in MVPA, 27mins(17-35) and STS transitions, 8(4-12), with no difference in total sedentary time: -33mins(-80-15). There were no differences in any PA measures post-PR compared to pre-PR (p < 0.05). CONCLUSION Daily step count and time spent in MVPA increased significantly during the PR week, solely due to increased PA on days participants attended PR.

Abstract
INTRODUCTION AND OBJECTIVES Pulmonary rehabilitation (PR) is a fundamental intervention to manage COPD, however, maintaining its benefits is challenging. Engaging in physical activity might help to prolong PR benefits. This study assessed the efficacy and effectiveness of a personalised community-based physical activity programme to sustain physical activity and other health-related PR benefits, in people with COPD. MATERIALS AND METHODS This was a multicentre, assessor blinded, randomised controlled trial. Following 12-weeks of PR, people with COPD were assigned to a six-months personalised community-based physical activity programme (experimental group), or to standard care (control group). Physical activity was assessed via: time spent in moderate to vigorous physical activities per day (primary outcome measure), steps/day and the brief physical activity assessment tool. Secondary outcomes included sedentary behaviour, functional status, peripheral muscle strength, balance, symptoms, emotional state, health-related quality of life, exacerbations and healthcare utilization. Assessments were performed immediately post-PR and after three- and six-months. Efficacy and effectiveness were evaluated using intention-to-treat and per-protocol analysis with linear mixed models. RESULTS Sixty-one participants (experimental group: n = 32; control group: n = 29), with balanced baseline characteristics between groups (69.6 ± 8.5 years old, 84 % male, FEV1 57.1 ± 16.7 %predicted) were included. Changes in all physical activity outcomes and in one-minute sit-to-stand were significantly different (P < 0.05) between groups at the six-month follow-up. In the remaining outcomes there were no differences between groups. CONCLUSIONS The community-based physical activity programme resulted in better physical activity levels and sit-to-stand performance, six-months after completing PR, in COPD. No additional benefits were observed for other secondary outcomes.

Effectiveness of virtual reality-based therapy in pulmonary rehabilitation of chronic obstructive pulmonary disease. A systematic review with meta-analysis. Heart Lung 2024; 65:1-10. [PMID: 38330853 DOI: 10.1016/j.hrtlng.2024.01.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2023] [Revised: 01/29/2024] [Accepted: 01/29/2024] [Indexed: 02/10/2024]
Abstract
BACKGROUND In addition to conventional pulmonary rehabilitation (PR) programs for the treatment of chronic obstructive pulmonary disease (COPD), the use of virtual reality-based therapy (VRBT) has been proposed as an effective complementary tool to be included in PR programs for COPD. OBJECTIVES To analyze the effectiveness of VRBT on functional capacity, pulmonary function, and functional mobility in patients with COPD. METHODS A meta-analysis was carried out through a bibliographic search in PubMed (Medline), WOS, PEDro, CINAHL, CENTRAL, and Scopus since inception up to June 2023. The risk of bias was assessed using the PEDro scale, and the effect was determined using the standardized mean difference (SMD) and its 95 % confidence interval (95 % CI) in a random effects model. RESULTS Five RCTs, providing data from 344 participants with a mean age 65.7 ± 5.3 years old, were included. The mean methodological quality of the studies included was good (6.8 ± 1.6 points). The meta-analysis showed that VRBT was effective in increasing functional capacity, assessed with the 6 Min Walking Test, (SMD=0.4, 95 % CI 0.07 to 0.71, p = 0.017); pulmonary function, assessed with FEV1 (SMD=0.33, 95 %CI 0.01 to 0.65, p = 0.048); and functional mobility, assessed with the Get Up and Go Test (SMD=0.77, 95 % CI 0.5 to 1.1, p<0.001) in patients with COPD. CONCLUSION VRBT is suggested to be effective in increasing functional capacity, pulmonary function, and functional mobility in patients with COPD. Non-immersive VRBT is the most used modality of VRBT in PR.

Abstract
PURPOSE Understanding the experiences of people with Chronic Obstructive Pulmonary Disease (COPD) using activity monitors in daily life could support the utilisation of technology within healthcare to increase physical activity and support self-management. This qualitative study aimed to explore the experiences of people with COPD using activity monitors at home in everyday life. METHODS Semi-structured face-to-face or telephone interviews were conducted with seven people with COPD between August 2018 and June 2020. Participants had all used an activity monitor within the last year (Fitbit, Garmin, or Apple Watch). Interviews were analysed in-depth using Interpretative Phenomenological Analysis (IPA). RESULTS Four themes, developed using IPA, highlight participants' engagement with activity monitors and integrating them into their lives: (1) Motivational features to monitor activity, (2) Importance of setting achievable goals, (3) Developing knowledge and awareness, and (4) Integration into everyday life for self-management. CONCLUSION Activity monitors were perceived to be beneficial and useful to people with COPD, not just for monitoring their activity, but also helping to self-manage their condition. Activity monitors may be a useful tool within rehabilitation and healthcare services for COPD.

Abstract
BACKGROUND Moderate to vigorous physical activity (MVPA) in patients with COPD affects their overall health outcomes, including symptom relief and improved quality of life. However, the magnitude of the effect of MVPA initiation on real-world clinical outcomes has not been well investigated. RESEARCH QUESTION How does MVPA initiation affect mortality and severe exacerbation in patients who have not engaged in MVPA prior to COPD diagnosis? STUDY DESIGN AND METHODS This study included patients with COPD aged ≥ 40 years who were not performing MVPA prior to COPD diagnosis and who had at least one health screening visit prior to and following their COPD diagnosis between January 1, 2010, and December 31, 2018. The main exposure was MVPA, defined as vigorous aerobic exercise > 20 min per day on ≥ 3 days per week or moderate aerobic exercise > 30 min per day on ≥ 5 days per week. The primary end point was all-cause mortality, and the secondary end point was initial severe exacerbation as the time to event following COPD diagnosis. RESULTS In total, 110,097 person-trials were included (27,564 MVPA increases and 82,533 control groups). No differences were observed between the covariates following matching. The adjusted hazards ratio of all-cause mortality for the MVPA group compared with the control group was 0.84 (95% CI, 0.79-0.89). In the subgroup analysis, patients aged > 65 years, female patients, those who had never smoked, and patients with a higher Charlson Comorbidity Index score displayed a stronger effect of MVPA on reducing mortality than younger male patients, those who had ever smoked, and patients with a lower Charlson Comorbidity Index score (Pinteraction < .05). The fully adjusted hazards ratio for the risk of severe exacerbation (MVPA group vs control) was 0.90 (95% CI, 0.87-0.94). INTERPRETATION Initiation of MVPA can potentially reduce mortality and severe exacerbations in patients with COPD, although personalized interventions and further clinical trials are necessary.

Development of a behavior change intervention to improve physical activity in patients with COPD using the behavior change wheel: a non-randomized trial. Sci Rep 2023; 13:22929. [PMID: 38129630 PMCID: PMC10739839 DOI: 10.1038/s41598-023-50099-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2023] [Accepted: 12/15/2023] [Indexed: 12/23/2023] Open
Abstract
The aim of this study was to evaluate whether a theory-based behavior change intervention could promote changes in physical activity (PA) and sedentary behavior (SB) among patients with chronic obstructive pulmonary disease (COPD), as well as its effects on symptoms of dyspnea, lung function, exercise capacity, self-efficacy, and health-related quality of life (HRQoL). A quasi-experimental design and convenience sampling were adopted. A total of 92 patients with stable COPD were recruited from outpatient and inpatient centers of two hospitals in Zhejiang Province, China. Both the experimental and control groups received standard medical care provided in the hospital. The experimental group performed a PA program based on the behavior change wheel theory. Outcomes were measured at baseline (T0) and after 4 weeks (T1), 8 weeks (T2), and 12 weeks of the intervention (T3). The primary outcome was PA measured by the International Physical Activity Questionnaire (IPAQ). Secondary outcomes included SB measured by the IPAQ, dyspnea measured by the modified Medical Research Council (mMRC) questionnaire, exercise capacity assessed by 6-min walk distance (6MWD), self-efficacy measured by the Exercise Self-Regulatory Efficacy Scale (EX-SRES), and HRQoL measured by the COPD Assessment Test (CAT). In addition, we measured lung function using a spirometer at baseline and 12 weeks. Of the 89 patients included in this study, 64 were male (71.91%), with a mean age of 67.03 ± 6.15 years. At 12 weeks, the improvements in PA, SB, mMRC, 6MWD, EX-SRES and CAT were all statistically significant (P < 0.05) in the experimental group compared to the control group. Repeated measures analysis of variance showed that there were group effects and time effects on total PA, SB, mMRC, 6MWD, EX-SRES, and CAT in both groups (P < 0.001). However, there was no significant difference in pulmonary function between the two groups before and after intervention (P < 0.05). The PA program based on theory significantly increased PA levels, reduced sedentary time, enhanced exercise capacity and self-efficacy as well as HRQoL in patients with stable COPD. Due to the limited intervention time in this study, the pulmonary function of COPD patients may not be reversed in a short time, and the long-term effect of this program on the pulmonary function of patients needs to be further explored.Trial registration: Clinical Trials.gov (ChiCTR2200060590).

Abstract
People with asthma tend to be less physically active and more sedentary than people without asthma. This narrative review aimed to present key considerations when addressing physical inactivity and sedentary behaviour in people with asthma by identifying barriers and facilitators, determinants and correlates, and intervention approaches. Using a search strategy, electronic databases were searched for relevant studies. Data extracted from studies were qualitatively synthesised. A total of 26 studies were included in the review. Six studies reported asthma symptoms as a barrier to physical activity, while four studies reported having a supportive network as a physical activity facilitator. Across studies, physical activity correlates/determinants were pulmonary function, exercise capacity, body mass index, dyspnoea, psychological health, and asthma control. Interventions that effectively improved physical activity in the short term were a step-based prescription programme, a weight loss programme incorporating aerobic and resistance training, and a weight loss lifestyle intervention, while a high-intensity interval training pulmonary rehabilitation program was effective in the long term. The collective findings suggest that a personalised physical activity programme incorporating different strategies is needed. There was minimal evidence to provide recommendations to optimise sedentary behaviour in asthma, and more research is needed on the topic.

Accuracy and Reliability of a Suite of Digital Measures of Walking Generated Using a Wrist-Worn Sensor in Healthy Individuals: Performance Characterization Study. JMIR Hum Factors 2023; 10:e48270. [PMID: 37535417 PMCID: PMC10436116 DOI: 10.2196/48270] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2023] [Revised: 05/22/2023] [Accepted: 06/21/2023] [Indexed: 08/04/2023] Open
Abstract
BACKGROUND Mobility is a meaningful aspect of an individual's health whose quantification can provide clinical insights. Wearable sensor technology can quantify walking behaviors (a key aspect of mobility) through continuous passive monitoring. OBJECTIVE Our objective was to characterize the analytical performance (accuracy and reliability) of a suite of digital measures of walking behaviors as critical aspects in the practical implementation of digital measures into clinical studies. METHODS We collected data from a wrist-worn device (the Verily Study Watch) worn for multiple days by a cohort of volunteer participants without a history of gait or walking impairment in a real-world setting. On the basis of step measurements computed in 10-second epochs from sensor data, we generated individual daily aggregates (participant-days) to derive a suite of measures of walking: step count, walking bout duration, number of total walking bouts, number of long walking bouts, number of short walking bouts, peak 30-minute walking cadence, and peak 30-minute walking pace. To characterize the accuracy of the measures, we examined agreement with truth labels generated by a concurrent, ankle-worn, reference device (Modus StepWatch 4) with known low error, calculating the following metrics: intraclass correlation coefficient (ICC), Pearson r coefficient, mean error, and mean absolute error. To characterize the reliability, we developed a novel approach to identify the time to reach a reliable readout (time to reliability) for each measure. This was accomplished by computing mean values over aggregation scopes ranging from 1 to 30 days and analyzing test-retest reliability based on ICCs between adjacent (nonoverlapping) time windows for each measure. RESULTS In the accuracy characterization, we collected data for a total of 162 participant-days from a testing cohort (n=35 participants; median observation time 5 days). Agreement with the reference device-based readouts in the testing subcohort (n=35) for the 8 measurements under evaluation, as reflected by ICCs, ranged between 0.7 and 0.9; Pearson r values were all greater than 0.75, and all reached statistical significance (P<.001). For the time-to-reliability characterization, we collected data for a total of 15,120 participant-days (overall cohort N=234; median observation time 119 days). All digital measures achieved an ICC between adjacent readouts of >0.75 by 16 days of wear time. CONCLUSIONS We characterized the accuracy and reliability of a suite of digital measures that provides comprehensive information about walking behaviors in real-world settings. These results, which report the level of agreement with high-accuracy reference labels and the time duration required to establish reliable measure readouts, can guide the practical implementation of these measures into clinical studies. Well-characterized tools to quantify walking behaviors in research contexts can provide valuable clinical information about general population cohorts and patients with specific conditions.

Kim KS, Park S. Impact of Lung-Related Polygenic Risk Scores on Chronic Obstructive Pulmonary Disease Risk and Their Interaction with w-3 Fatty Acid Intake in Middle-Aged and Elderly Individuals. Nutrients 2023; 15:3062. [PMID: 37447386 DOI: 10.3390/nu15133062] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2023] [Revised: 07/05/2023] [Accepted: 07/05/2023] [Indexed: 07/15/2023] Open
Abstract
Chronic obstructive pulmonary disease (COPD) is a complex, progressive respiratory disorder with persistent airflow limitation and tissue destruction. We aimed to explore the genetic impact of COPD and its interaction with nutrient intake in 8840 middle-aged and elderly individuals from the Ansan/Ansung cohorts. Participants were diagnosed with COPD if the ratio of forced expiratory volume in 1 s (FEV1) to forced vital capacity (FVC) was less than 0.7 using spirometry, and if they were previously diagnosed with COPD by a physician. Genome-wide association studies (GWAS) were performed to screen for genetic variants associated with COPD risk. Among them, we selected the genetic variants that exhibited interactions using the generalized multifactor dimensionality reduction (GMDR) method. The polygenic risk score (PRS) was computed by summing the number of risk alleles in the SNP-SNP interaction models that adhered to specific rules. Subsequently, participants were categorized into low-PRS, medium-PRS, and high-PRS groups. The participants with COPD exhibited significantly lower FEV1/FVC ratios (0.64) than those without COPD (0.82). It was positively associated with inflammation markers (serum C-reactive protein and white blood cell levels). A higher proportion of COPD participants were smokers and engaged in regular exercise. The 5-SNP model consisted of FAM13A_rs1585258, CAV1_rs1997571, CPD_rs719601, PEPD_rs10405598, and ITGA1_rs889294, and showed a significant association with COPD risk (p < 0.001). Participants in the high-PRS group of this model had a 2.2-fold higher risk of COPD than those in the low-PRS group after adjusting for covariates. The PRS interacted with w-3 fatty acid intake and exercise, thus influencing the risk of COPD. There was an increase in COPD incidence among individuals with a higher PRS, particularly those with low consumption of w-3 fatty acid and engaged in high levels of exercise. In conclusion, adults with a high-PRS are susceptible to COPD risk, and w-3 fatty acid intake and exercise may impact the risk of developing COPD, potentially applying to formulate precision medicines to prevent COPD.

Effects of Ipratropium Bromide Combined with Traditional Chinese Medicine Intervention on the Pulmonary Function and Psychological Status of Patients with Chronic Obstructive Pulmonary Disease. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2023; 2023:6483785. [PMID: 36798728 PMCID: PMC9928514 DOI: 10.1155/2023/6483785] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/09/2022] [Revised: 09/28/2022] [Accepted: 10/09/2022] [Indexed: 02/10/2023]
Abstract
Recently, most scholars have advocated multidisciplinary comprehensive intervention measures for chronic obstructive pulmonary disease (COPD) to improve lung function, relieve symptoms of dyspnea, and improve quality of life. Traditional Chinese medicine (TCM) has rich experience in the treatment of various respiratory system diseases and the rehabilitation of their syndrome differentiation. In this study, total 68 patients with COPD from November 2019 to November 2021 in the hospitals were divided into the control group, ipratropium bromide (IB)-treated group, and IB + TCM-treated group for clinical efficacy observation and to explore the effect of IB combined with TCM on the pulmonary function and psychological status of COPD patients. Patients in the control group were subjected to routine oxygen inhalation, cough and expectorant, and antiviral treatments, while the patients in the IB-treated group were treated with IB and those received in the control group. Patients in the IB + TCM-treated group were treated with IB and TCM intervention. All patients were treated for a month. The results showed that after different interventions, the levels of FEV1, FEV1% pred, FVC, and PEF (P < 0.05) were significantly increased in all the groups, while levels of TNF-α, IL-6, IL-8, and CRP in serum as well as Hamilton Anxiety Scale and Hamilton Depression scores were significantly decreased. Compared with the control group and IB-treated group, the IB + TCM-treated group presented the greatest changes on all abovementioned indicators and the lowest total incidence of adverse reactions, indicating the biggest improvement of IB + TCM on the symptoms of COPD patients. Therefore, the combination of IB and TCM intervention effectively improved the pulmonary function and psychological status of COPD patients and could be used as an important adjunct for COPD treatment.
