Pulmonary rehabilitation for pneumoconiosis: protocol for a systematic review and meta-analysis.

ABSTRACT: INTRODUCTION:Pneumoconiosis is characterised by diffuse fibrosis in lung tissue, and its incidence is on the rise. At present, there are limited therapeutic options for pneumoconiosis. Pulmonary rehabilitation (PR) has been widely used to treat pneumoconiosis?however, there is limited evidence concerning its efficacy. Therefore, we plan to conduct a systematic review to investigate the efficacy and safety of PR for pneumoconiosis. METHODS AND ANALYSIS:The following databases will be searched from their inception to 1 April 2019: PubMed, Embase, The Cochrane Library, Web of Science, Chinese Biomedical Literature Database, China National Knowledge Infrastructure, Chongqing VIP and Wanfang Data. Randomised controlled trials of PR for pneumoconiosis will be included. Primary outcomes will include 6?min walk distance and St. George's Respiratory Questionnaire. Study selection, extraction of data and assessment of study quality each will be independently undertaken. Statistical analysis will be conducted using Review Manager software. ETHICS AND DISSEMINATION:This systematic review will provide up-to-date information on PR for pneumoconiosis. The review does not require ethical approval and will be disseminated electronically through a peer-reviewed publication or conference presentations. PROSPERO REGISTRATION NUMBER:CRD42018095266.

Project description:This study evaluated the efficacy and safety of pulmonary rehabilitation (PR) for pneumoconiosis. We systematically searched PubMed, Embase, The Cochrane Library, Web of Science, SinoMed, CNKI, VIP databases and Wanfang Data from their inception to June 1, 2019. A systematic review and meta-analysis of randomized controlled trials (RCTs) of PR for pneumoconiosis was conducted and reported in compliance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Two reviewers independently screened literature, extracted data, and assessed bias risk. All statistical analyses were performed using the RevMan software. Sixteen RCTs with 1307 subjects were ultimately included for analysis. Compared with routine treatment, PR was able to improve the 6-minute walking distance (mean difference (MD) 69.10, 95% confidence interval (CI) 61.95-76.25); the 36-Item Short Form Health Survey total score (MD 17.60, 95% CI 13.59-21.61); physical function score (MD 15.45, 95% CI 3.20-27.69); role physical score (MD 17.87, 95% CI 12.06-23.69); body pain score (MD 14.34, 95% CI 10.33-18.36); general health score (MD 20.86, 95% CI 16.87-24.84); vitality score (MD 11.66, 95% CI 0.18-23.13); social function score (MD 9.67, 95% CI 1.27-18.08); mental health score (MD 20.60, 95% CI 13.61-27.59); forced vital capacity (FVC) (MD 0.20, 95% CI 0.12-0.29); forced expiratory volume in 1?s (FEV1) (MD 0.23, 95% CI 0.09-0.38); FEV1% (MD 5.19, 95% CI 1.48-8.90); maximal voluntary ventilation (MD 4.47, 95% CI 1.14-7.81); reduction in the St. George's Respiratory Questionnaire score (MD -9.60, 95% CI -16.40 to -2.80); and the modified Medical Research Council Scale score. Furthermore, PR did not increase the FEV1/FVC (MD 3.61, 95% CI -3.43 to 10.65), nor the emotional score (MD 6.18, 95% CI -23.01 to 35.38) compared with the control. We found no reports of adverse events associated with PR. Thus, to some extent, PR can improve functional capacity and quality of life in patients with pneumoconiosis. However, these results should be interpreted with caution because of high heterogeneity. This trial is registered with registration number CRD42018095266.

Project description:BackgroundPulmonary rehabilitation (PR), delivered as a supervised multidisciplinary program including exercise training, is one of the cornerstones in the chronic obstructive pulmonary disease (COPD) management. We performed a systematic review and meta-analysis to assess the effect on mortality of a supervised early PR program, initiated during or within 4 weeks after hospitalization with an acute exacerbation of COPD compared with usual post-exacerbation care or no PR program. Secondary outcomes were days in hospital, COPD related readmissions, health-related quality of life (HRQoL), exercise capacity (walking distance), activities of daily living (ADL), fall risk and drop-out rate.MethodsWe identified randomized trials through a systematic search using MEDLINE, EMBASE and Cocharne Library and other sources through October 2017. Risk of bias was assessed regarding randomization, allocation sequence concealment, blinding, incomplete outcome data, selective outcome reporting, and other biases using the Cochrane Risk of Bias tool.ResultsWe included 13 randomized trials (801 participants). Our meta-analyses showed a clinically relevant reduction in mortality after early PR (4 trials, 319 patients; RR?=?0.58 (95% CI: [0.35 to 0.98])) and at the longest follow-up (3 trials, 127 patients; RR?=?0.55 (95% CI: [0.12 to 2.57])). Early PR reduced number of days in hospital by 4.27 days (1 trial, 180 patients; 95% CI: [-?6.85 to -?1.69]) and hospital readmissions (6 trials, 319 patients; RR?=?0.47 (95% CI: [0.29 to 0.75])). Moreover, early PR improved HRQoL and walking distance, and did not affect drop-out rate. Several of the trials had unclear risk of bias in regard to the randomization and blinding, for some outcome there was also a lack of power.ConclusionModerate quality of evidence showed reductions in mortality, number of days in hospital and number of readmissions after early PR in patients hospitalized with a COPD exacerbation. Long-term effects on mortality were not statistically significant, but improvements in HRQoL and exercise capacity appeared to be maintained for at least 12 months. Therefore, we recommend early supervised PR to patients with COPD-related exacerbations. PR should be initiated during hospital admission or within 4 weeks after hospital discharge.

Project description:BackgroundPulmonary rehabilitation (PR) has been proposed as an effective method for many respiratory diseases. However, the effects of exercise-based PR on asthma are currently inconclusive. This review aimed to investigate the effects of exercise-based PR on adults with asthma.MethodsThe PubMed, Embase, Cochrane Library, Web of Science, International Clinical Trials Registry Platform and ClinicalTrials.gov databases were searched from inception to 31 July 2019 without language restriction. Randomized controlled trials (RCTs) investigating the effects of exercise-based PR on adults with asthma were included. Study selection, data extraction and risk of bias assessment were performed by two investigators independently. Meta-analysis was conducted by RevMan software (version 5.3). Evidence quality was rated by the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) system.ResultsTen literatures from nine studies (n?=?418 patients) were identified. Asthma quality of life questionnaire total scores (MD?=?0.39, 95% CI: 0.02 to 0.76) improved significantly in the experimental group compared to control group, including activity domain scores (MD?=?0.58, 95% CI: 0.21 to 0.94), symptom domain scores (MD?=?0.52, 95% CI: 0.19 to 0.85), emotion domain scores (MD?=?0.53, 95% CI: - 0.03 to 1.09) and environment domain scores (MD?=?0.56, 95% CI: 0.00 to 1.11). Both the 6-min walk distance (MD?=?34.09, 95% CI: 2.51 to 65.66) and maximum oxygen uptake (MD?=?4.45, 95% CI: 3.32 to 5.58) significantly improved. However, improvements in asthma control questionnaire scores (MD?=?- 0.25, 95% CI: - 0.51 to 0.02) and asthma symptom-free days (MD?=?3.35, 95% CI: - 0.21 to 6.90) were not significant. Moreover, there was no significant improvement (MD?=?0.10, 95% CI: - 0.08 to 0.29) in forced expiratory volume in 1 s. Nonetheless, improvements in forced vital capacity (MD?=?0.23, 95% CI: 0.08 to 0.38) and peak expiratory flow (MD?=?0.39, 95% CI: 0.21 to 0.57) were significant.ConclusionsExercise-based PR may improve quality of life, exercise tolerance and some aspects of pulmonary function in adults with asthma and can be considered a supplementary therapy. RCTs of high quality and large sample sizes are required.Clinical trial registrationThe review was registered with PROSPERO (The website is https://www.crd.york.ac.uk/prospero/ , and the ID is CRD42019147107).

Project description:ObjectiveThe present systematic review and meta-analysis of randomized clinical trials (RCTs) aimed to investigate the effects of pulmonary rehabilitation in individuals with chronic obstructive pulmonary disease (COPD).MethodsThe RCTs of pulmonary rehabilitation programs published between 1999 and 2021 were retrieved from electronic databases (PubMed, Cochrane Library, and Embase). Two reviewers independently assessed the topical relevance and trial quality and extracted data for meta-analysis using the Stata software version 14.0.ResultsA total of 39 trials involving 2,397 participants with COPD were evaluated. We found that patients who received pulmonary rehabilitation program had significant improvement in the 6-min walk test (6MWT), St. George Respiratory Questionnaire score, and the modified British Medical Research Council score as compared to those who received usual care. Yoga and Tai Chi showed significant improvement in the forced expiratory volume (FEV1)% in 1 s predicted value. However, no significant difference was detected in the modified Borg score, forced vital capacity (FVC), and FEV1/FVC predicted value between the pulmonary rehabilitation and usual care groups.ConclusionYoga and Tai Chi showed a significant improvement in the FEV1% predicted value. Also, pulmonary rehabilitation program improved the exercise capacity, the quality of life, and dyspnoea in patients with COPD.Key messagesA total of 39 trials involving 2,397 participants with COPD were evaluated.We found that patients who received pulmonary rehabilitation program had significant improvement in the 6MWT, St. George Respiratory Questionnaire score, and the modified British Medical Research Council score as compared to those who received usual care.Yoga and Tai Chi showed significant improvement in the FEV1% predicted value.No significant difference was detected in the modified Borg score, FVC, and FEV1/FVC predicted value between the pulmonary rehabilitation and usual care groups.

Project description:BackgroundStroke is the second leading cause of death worldwide, and 53.4% of stroke survivors suffer from post-stroke cognitive impairment. Post-stroke cognitive impairment can increase hospitalization rate and cost of care and decrease the quality of life of stroke patients. To date, multiple cognitive rehabilitation interventions have been tested in stroke populations with post-stroke cognitive impairment. However, the most efficacious intervention has not been established. This systematic review aims to compare the efficacy of cognitive rehabilitation interventions for patients with post-stroke cognitive impairment.MethodsWe will search MEDLINE, EMBASE, CENTRAL, PsycINFO, CINAHL, PubMed, and clinical trial registries to identify eligible randomized clinical trials with no restrictions in the date of publication and language. Studies conducted with patients aged 18 or over, with the presence of cognitive impairment after being diagnosed with stroke will be included. Studies will be restricted to randomized controlled trials comparing a cognitive rehabilitation intervention with another intervention. The primary outcome is any clinical changes in the general or specific cognitive domain (e.g., executive function, attention, memory, or perception). The secondary outcomes that will be collected include adverse effects (e.g., stroke, disability, or mortality) and quality of life. Two independent reviewers will assess articles to identify trials eligible for inclusion. Data extraction and risk of bias assessment of the included studies will also be done independently. Any discrepancies will be solved by discussion, or a third reviewer will be consulted if necessary. A meta-analysis will be carried out if appropriate.DiscussionThis systematic review for patients with post-stroke cognitive impairment will assess the efficacy of cognitive rehabilitation interventions. And our results will help clinical decision-making and support the development of clinical practice guidelines.Trial registrationSystematic review registration: PROSPERO CRD42020173988.
