Nutritional Supplementation during Pulmonary Rehabilitation in COPD: A Systematic Review

Abstract

Uptake of nutritional supplementation during pulmonary rehabilitation (PR) for people with chronic obstructive pulmonary disease (COPD) has been limited by an absence of rigorous evidence-based studies supporting use. Our objective were to report and summarise the current evidence supporting use of nutritional supplementation to improve outcomes during pulmonary rehabilitation in stable COPD patients. A systematic search was conducted up to May 7th, 2019 (registration number CRD42018089142). The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used. Six databases were included: Medical Literature Analysis and Retrieval System Online or MEDLARS Online (Medline), Allied and Complementary Medicine Database (AMED), the Cochrane Database of Systematic Reviews, Excerpta Medica dataBASE (Embase), Cumulative Index of Nursing and Allied Health Literature (CINAHL), and Web of Science. This systematic search generated 580 initial matches, of which 24 studies (1035 COPD participants) met the pre-specified criteria and were included. Our analysis does not confirm an impact of nutritional supplementation during PR, but studies, supplements and PR programmes were heterogeneous in nature. There is currently insufficient evidence on the effect of nutritional supplementation on improving outcomes during PR in patients with COPD. Therefore, controversy remains and further research is needed.

Prevalence, Severity and Mortality associated with COPD and Smoking in patients with COVID-19: A Rapid Systematic Review and Meta-Analysis

“…Viral infections in COPD patients increase systemic inflammation with slow recovery of reported symptoms (37,38). In addition to the effects of COVID-19, patients with COPD have various comorbidities, some of which are associated with increased risk of hospitalisation (39)(40)(41).…”

In addition to the effects of COVID-19, patients with COPD have various comorbidities, some of which are associated with increased risk of hospitalisation (39-41). According to recent systematic reviews, the prevalence of comorbidities in COVID-19 patients was high and these comorbidities were associated with increased disease severity (42, 43).…”

Usefulness of Pulmonary Rehabilitation in Non-Small Cell Lung Cancer Patients Based on Pulmonary Function Tests and Muscle Analysis Using Computed Tomography Images

“…Education programs include smoking-cessation education, breathing re-training (pursed-lip breathing, diaphragmatic breathing, and segmental breathing), secretion removal training (coughing exercise, huffing, and assisted coughing), and postural drainage [21]. Furthermore, the addition of dietary education and emotional support programs would contribute to better outcomes [22,23]. The ideal form of pulmonary rehabilitation involves a harmonized combination of exercises and education aiming to correct the patients' lifestyle and to encourage them to continuously engage in daily exercise.…”
