Effects of Mawangdui exercise intervention on the pulmonary function, physical fitness and quality of life in stable chronic obstructive pulmonary disease patients: A randomised controlled trial

BACKGROUND

Physical exercise intervention in pulmonary rehabilitation is recommended to increase strength, endurance, and flexibility in chronic obstructive pulmonary disease (COPD). However, certain physical intervention may be restrictive to COPD patients, as it induces fatigue and shortness of breath. Mawangdui exercise, a low-to-medium-intensity aerobic exercise, has been gaining popularity in China as an adjuvant physical therapy, particularly for patients with contraindications to exercise, to improve their health.

OBJECTIVE

To investigate the effectiveness of the traditional Chinese Mawangdui exercise for patients with COPD in a mild to moderate stable stage.

METHODS

A total of 54 COPD patients in stable stage (Mawangdui group, n = 27; control group, n = 27) were enroled for a period of 12-weeks. The Mawangdui group practised the Mawangdui exercise, while the control group maintained daily activities without additional exercise. The outcomes measurements were pulmonary function, exercise capacity, back-leg-chest muscle strength, sit-and-reach flexibility, dyspnoea symptoms, and quality of life. The outcomes were assessed at baseline, 24 h, 6 weeks, and 12 weeks post-intervention.

RESULTS

Improvements were observed for Borg CR-10 score, SpO2, BMI, body fat%, fat mass, flexibility mMRC, and SGRQ scores (p < 0.05) at 12 weeks. At week 12, Mawangdui group showed improved exercise capacity (6MWT mean difference 63.39 m, CI 48.36－78.40), back-leg-chest muscle strength (mean difference 5.92 kg, CI -2.57－-14.41), and dyspnoea (CAT score mean difference -5.50, CI -6.42－-4.59) in per-protocol population. However, FEV1, FVC, FEV1% pred, and fat-free mass did not show improvements with Mawangdui exercise.

CONCLUSION

COPD patients in stable stage who performed Mawangdui exercise for 12 weeks improved exercise capacity, dyspnoea, muscle strength, flexibility, BMI, body fat%, fat mass and quality of life. Therefore, Mawangdui exercise is recommended for COPD patients in the stable stage to improve physical fitness and quality of life.

Physical and mental health trajectories: A longitudinal SF-36 analysis in Alpha-1 antitrypsin deficiency-associated COPD

BACKGROUND

The Short Form 36-Item Health Survey (SF-36) is a health-related quality of life (HRQoL) measure validated in people with chronic obstructive pulmonary disease (COPD). While physical health is often more impaired than mental health in people with COPD, research on alpha-1 antitrypsin deficiency (AATD)-associated COPD is limited. This longitudinal study examines changes in physical and mental health in individuals with AATD and associated factors.

METHODS

Analyses included participants of AlphaNet, a disease management program for individuals with AATD-associated lung disease who are prescribed augmentation therapy. Norm-based SF-36 scores for mental and physical component summaries (MCS and PCS) and 8 scales were analyzed. Linear mixed models evaluated mean changes in SF-36 scores over time.

RESULTS

The study included 2165 participants (mean age 56.9 ± 10.0 years, 47.0 % female). At enrollment, mean PCS score was 37.5 ± 9.6, and mean MCS score was 51.9 ± 10.5. Mean mMRC dyspnea score was 2.3 ± 1.3; 54.6 % had ≥2 exacerbations annually, and 46.5 % used oxygen regularly. Average follow-up was 6.6 ± 3.2 years. The HRQoL remained stable; MCS improved by 0.16 points/year (p < 0.0001), while the PCS score declined by 0.49 points/year (p < 0.0001). Subscales followed similar trends.

CONCLUSIONS

At baseline, mental HRQoL scores were higher than physical HRQoL scores, indicating better mental health than physical health in this cohort with AATD-associated lung disease. Stable HRQoL with a slight improvement in mental scores over time and a small decrease in physical scores may be a unique feature of this cohort. Further studies are needed to correlate these findings with disease-specific instruments and patient physiology.

Assessment of health-related quality of life in patients with nontuberculous mycobacterial pulmonary disease: A comprehensive review

The global incidence of nontuberculous mycobacterial pulmonary disease (NTM-PD) is increasing. The primary aim of pharmacotherapeutic treatment for NTM-PD is to achieve negative bacterial conversion, but this goal is challenging, especially in cases with poor prognosis factors. Moreover, recurrence frequently occurs following successful treatment. Consequently, patient-reported outcomes (PROs) have attracted an increasing amount of attention due to their potential to elucidate the pathophysiology of NTM-PD. The current review article aimed to describe the current understanding of PROs related to health-related quality of life (HRQoL). HRQoL is influenced by a variety of factors; notably, those factors associated with the prognosis of NTM-PD significantly impair HRQoL. In patients with refractory NTM-PD, HRQoL tends to worsen over time. Assessing HRQoL through PROs involves short-term or long-term evaluation tools, which are selected based on their relevance to the patient's condition and the clinician's goals. Understanding the nuances of PROs can be helpful for delivering empathetic care tailored to patients in even the most complex treatment scenarios.

Influence of physical activity on the prognosis of COPD patients: the HADO.2 score - health, activity, dyspnoea and obstruction

Objective

The aim of this study was to create a prognostic instrument for COPD with a multidimensional perspective that includes physical activity (PA). The score also included health status, dyspnoea and forced expiratory volume in 1 s (HADO.2 score).

Methods

A prospective, observational, non-intervention study was carried out. Patients were recruited from the six outpatient clinics of the respiratory service of a single university hospital. The component variables of the HADO.2 score and BODE index were studied, and PA was measured using an accelerometer. The outcomes for the HADO.2 score were mortality and hospitalisations during follow-up and an exploration of the correlation with health-related quality of life at the moment of inclusion in the study.

Results

401 patients were included in the study and followed up for three years. The HADO.2 score showed good predictive capacity for mortality: C-index 0.79 (0.72-0.85). The C-index for hospitalisations was 0.72 (0.66-0.77) and the predictive ability for quality of life, as measured by R2, was 0.63 and 0.53 respectively for the Saint George's Respiratory Questionnaire and COPD Assessment Test.

Conclusions

There was no statistically significant difference between the mortality predictive capacity of the HADO.2 score and the BODE index. Adding PA to the original BODE index significantly improved the predictive capacity of the index. The HADO.2 score, which includes PA as a key variable, showed good predictive capacity for mortality and hospitalisations. There were no differences in the predictive capacity of the HADO.2 score and the BODE index.

Health-related quality of life and its associated factors in patients with chronic obstructive pulmonary disease

OBJECTIVE

The present study aimed to evaluate HRQOL and to explore the factors associated with poor HRQOL among patients with COPD.

METHODS

In the present cross-sectional study, the validated St George's Respiratory Questionnaire for COPD patients (SGRQ-C) was used to evaluate HRQOL among 702 patients with COPD at two major hospitals in Jordan in the period between January and April 2022. Quantile regression analysis was used to explore the factors associated with HRQOL among the study participants.

RESULTS

According to SGRQ-C, the HRQOL of the study participants was greatly impaired with a total SGRQ of 55.2 (34-67.8). The highest impairment in the HRQOL was in the impact domain with a median of 58.7 (29-76.3). Increased number of prescribed medications (β = 1.157, P<0.01), older age (β = 0.487, P<0.001), male gender (β = 5.364, P<0.01), low education level (β = 9.313, P<0.001), low and moderate average income (β = 6.440, P<0.05, and β = 6.997, P<0.01, respectively) were associated with poorer HRQOL. On the other hand, being married (β = -17.122, P<0.001), living in rural area (β = -6.994, P<0.01), non-use of steroids inhalers (β = -3.859, P<0.05), not receiving long acting muscarinic antagonists (LAMA) (β = -9.269, P<0.001), not receiving LABA (β = -8.243, P<0.001) and being adherent to the prescribed medications (β = -6.016, P<0.001) were associated with improved HRQOL. Furthermore, lower disease severity (stage A, B, and C) (β = -23.252, -10.389, and -9.696 respectively, P<0.001), and the absence of comorbidities (β = -14.303, P<0.001) were associated with better HRQOL.

CONCLUSIONS

In order to maximize HRQOL in patients with COPD, future COPD management interventions should adopt a multidisciplinary approach involving different healthcare providers, which aims to provide patient-centered care, implement personalized interventions, and improve medication adherence, particularly for patients who are elderly, males, have low socioeconomic status, receive multiple medications and have multiple comorbid diseases.

Improved exercise capacity results in a survival benefit after endobronchial valve treatment

BACKGROUND

Bronchoscopic lung volume reduction using endobronchial valves (EBV) is a treatment option for selected patients with advanced emphysema. The treatment significantly improves pulmonary function, exercise capacity, quality of life, and potentially improves survival. Our main aim was to assess whether treatment response significantly influences survival time after EBV treatment.

METHODS

We evaluated treatment response at 6-week and 1-year follow-up of all patients treated with EBVs between 2008 and 2020. Survival status was retrieved on December 1, 2021. Patients were defined as responders or non-responders based on known minimal important differences for FEV₁, residual volume (RV), RV/Total Lung Capacity (TLC) ratio, 6-min walk distance (6MWD), St. George's Respiratory Questionnaire (SGRQ), target lobe volume reduction (TLVR), and complete lobar atelectasis. Uni- and multivariate cox regression models were used to evaluate the effect of response on survival time.

RESULTS

A total of 428 patients were included. EBV treatment resulted in significant improvements in pulmonary function, exercise capacity and quality of life. Median survival was 8.2 years after treatment. SGRQ and 6MWD response were independent predictors for improved survival time (Hazard Ratio (HR) 0.50 [0.28-0.89], p = .02 and HR 0.54 [0.30-0.94], p = .03, respectively). The presence of a complete lobar atelectasis did not significantly affect survival, neither did pulmonary function improvements.

CONCLUSIONS

Our results suggest that improvement in exercise capacity and quality of life after EBV treatment are associated with a survival benefit, independent of improvements in pulmonary function, reduction in target lobe volume or the presence of complete lobar atelectasis.

Promoting Chronic Obstructive Pulmonary Disease Wellness through Remote Monitoring and Health Coaching: A Clinical Trial

Rationale: Quality of life (QoL) matters the most to patients with chronic obstructive pulmonary disease (COPD) and is associated with healthcare usage and survival. Pulmonary rehabilitation is the most effective intervention in improving QoL but has low uptake and adherence. Home-based programs are a proposed solution. However, there is a knowledge gap on effective and sustainable home-based programs impacting QoL in patients with COPD. Objectives: To determine whether remote patient monitoring with health coaching improves the physical and emotional disease-specific QoL measured by the Chronic Respiratory Questionnaire (CRQ). Methods: This multicenter clinical trial enrolled 375 adult patients with COPD, randomized to a 12-week remote patient monitoring with health coaching (n = 188) or wait-list usual care (n = 187). Primary outcomes include physical and emotional QoL measured by the CRQ summary scores. Prespecified secondary outcomes included the CRQ domains: dyspnea, CRQ-fatigue, CRQ-emotions, CRQ-mastery, daily physical activity, self-management abilities, symptoms of depression/anxiety, emergency room/hospital admissions, and sleep. Results: Participant age: 69 ± 9 years; 59% women; forced expiratory volume in 1 second percent predicted: 45 ± 19. At 12 weeks, there was a significant and clinically meaningful difference between the intervention versus the control group in the physical and emotional CRQ summary scores: change difference (95% confidence interval): 0.54 points (0.36-0.73), P < 0.001; 0.51 (0.39-0.69), P < 0.001, respectively. In addition, all CRQ domains, self-management, daily physical activity, sleep, and depression scores improved (P < 0.01). CRQ changes were maintained at 24 weeks. Conclusions: Remote monitoring with health coaching promotes COPD wellness and behavior change, given its effect on all aspects of QoL, self-management, daily physical activity, sleep, and depression scores. It represents an effective option for home-based rehabilitation. Clinical trial registered with clinicaltrials.gov (NCT03480386).
