ItemEfficacy of Repeating Pulmonary Rehabilitation in People with COPD: A Systematic Review(DOVE MEDICAL PRESS LTD, 2022-01-01)BACKGROUND: Pulmonary rehabilitation is an effective intervention for people with chronic obstructive pulmonary disease (COPD). People with COPD undertake repeat programs, but synthesis of evidence regarding such practice has not been undertaken. The aim of this systematic review was to establish the effects of repeating pulmonary rehabilitation subsequent to an initial program in people with COPD. METHODS: Studies where participants with COPD undertook >1 pulmonary rehabilitation program were included, incorporating RCT (randomized controlled trial) and non-randomized studies. Electronic database searches were undertaken. Two authors independently undertook study identification, data extraction and risk of bias assessment. The primary outcome was health-related quality of life (HRQoL); secondary outcomes were exercise capacity, hospitalizations and exacerbations, adherence, mortality and adverse events. Narrative synthesis was undertaken for clinically heterogeneous trials. Data from RCTs and non-randomized studies were not combined for analysis. RESULTS: Ten included studies (2 RCTs) involved 907 participants with COPD (n=653 had undertaken >1 program). The majority of studies were at high risk of bias. One RCT (n=33) reported no difference in HRQol after a repeat program vs usual care following exacerbation (Chronic Respiratory Disease Questionnaire dyspnea domain score MD 0.4, 95% CI -0.5 to 3). In stable patients, clinically important and statistically significant improvements in HRQoL and exercise capacity were reported after repeat programs, but of a smaller magnitude than initial programs. There was evidence for reductions in exacerbations and hospitalizations, and shorter hospital length of stay for patients who repeated a program twice in 12 months compared to those who repeated once. No data for mortality or adverse events were available. CONCLUSION: This systematic review provides limited evidence for benefits of repeating pulmonary rehabilitation in people with COPD, including improved HRQoL and exercise capacity, and reduced hospitalizations. However, most studies have high risk of bias, which reduces the certainty of these conclusions. STUDY REGISTRATION: PROSPERO (CRD42020215093).

ItemRoutine lung volume recruitment in boys with Duchenne muscular dystrophy: a randomised clinical trial(BMJ PUBLISHING GROUP, 2022-03-01)BACKGROUND: Impaired cough results in airway secretion retention, atelectasis and pneumonia in individuals with Duchenne muscular dystrophy (DMD). Lung volume recruitment (LVR) stacks breaths to inflate the lungs to greater volumes than spontaneous effort. LVR is recommended in DMD clinical care guidelines but is not well studied. We aimed to determine whether twice-daily LVR, compared with standard of care alone, attenuates the decline in FVC at 2 years in boys with DMD. METHODS: In this multicentre, assessor-blinded, randomised controlled trial, boys with DMD, aged 6-16 years with FVC >30% predicted, were randomised to receive conventional treatment or conventional treatment plus manual LVR twice daily for 2 years. The primary outcome was FVC % predicted at 2 years, adjusted for baseline FVC % predicted, age and ambulatory status. Secondary outcomes included change in chest wall distensibility (maximal insufflation capacity minus FVC) and peak cough flow. RESULTS: Sixty-six boys (36 in LVR group, 30 in control) were evaluated (median age (IQR): 11.5 years (9.5-13.5), median baseline FVC (IQR): 85% predicted (73-96)). Adjusted mean difference in FVC between groups at 2 years was 1.9% predicted (95% CI -6.9% to 10.7%; p=0.68) in the direction of treatment benefit. We found no differences in secondary outcomes. CONCLUSION: There was no difference in decline in FVC % predicted with use of twice-daily LVR for boys with DMD and relatively normal lung function. The burden associated with routine LVR may outweigh the benefit. Benefits of LVR to maintain lung health in boys with worse baseline lung function still need to be clarified.
