Phenotyping and the characterization of chronic obstructive pulmonary disease (COPD) is currently an active area of interest. The perspectives gleaned from evaluating COPD in the context of exercise lend new insights into this endeavor. Pulmonary rehabilitation centers are uniquely positioned to generate such clinical observations and have enhanced an understanding of the disease processes that are involved in COPD. This review and commentary discusses the various patterns of exercise intolerance and characterizes COPD from the perspectives of clinicians caring for persons with COPD...

BACKGROUND/OBJECTIVES: None of the cutoff points for fat-free mass index (FFMI) were tested for the Brazilian population, and it is unknown whether the available ones are able to discriminate extrapulmonary disease manifestations. This cross-sectional study aims to develop and validate a cutoff point for FFM depletion based on Brazilian patients with chronic obstructive pulmonary disease (COPD) and to verify its association and of previously published cutoffs with extrapulmonary manifestations...

One of the primary objectives in management of chronic obstructive pulmonary disease (COPD) is preventing decrease in lung function and reducing the annual number of acute exacerbations of COPD (AECOPD). An oral course of systemic corticosteroids is a commonly used treatment in AECOPD. We hypothesize that this treatment also increases exercise performance and decreases muscle fatigue. In a randomized double-blinded, parallel, placebo-controlled trial, we investigated 14 men (8 on prednisolone 37.5 mg vs. 6 on placebo) with severe and very severe COPD...

OBJECTIVE: Pulmonary rehabilitation improves exercise tolerance in patients with chronic obstructive pulmonary disease (COPD). However, many patients do not have access to pulmonary rehabilitation programs. We hypothesized that an alternative to pulmonary rehabilitation to improve exercise tolerance is the practice of pranayama, or yoga breathing, which could be done independently at home. We also sought to determine whether yoga nonprofessionals could adequately teach pranayama to patients...

RATIONALE: A substantial proportion of subjects without overt airflow obstruction have significant respiratory morbidity and structural abnormalities on computed tomography (CT). Whether regions of the lung that appear normal using traditional CT criteria have mild disease is not known. OBJECTIVE: To identity subthreshold structural disease in normal appearing lung regions in smokers. METHODS: We analyzed 8034 subjects with complete inspiratory and expiratory CT data participating in COPDGene including 103 lifetime non-smokers...

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a public health problem. Interprofessional collaboration and health promotion interventions such as exercise training, education, and behaviour change are cost effective, have a good effect on health status, and are recommended in COPD treatment guidelines. There is a gap between the guidelines and the healthcare available to people with COPD. The aim of this study was to increase the understanding of what shapes the provision of primary care services to people with COPD and what healthcare is offered to them from the perspective of healthcare professionals and managers...

BACKGROUND: People with dementia are at high risk for falls. However, little is known of the features causing falls in Alzheimer disease (AD). Our aim was to investigate how participants with AD fall. METHODS: In the FINALEX (Finnish Alzheimer Disease Exercise Trial) study, participants' (n = 194) falls were followed up for 1 year by diaries kept by their spouses. RESULTS: The most common reason for falls (n = 355) was stumbling (n = 61). Of the falls, 123 led to injuries, 50 to emergency department visits, and 13 to fractures...

Pulmonary hypertension (PH) complicating chronic obstructive pulmonary disease (COPD-PH) and interstitial lung disease (ILD-PH) (World Health Organization [WHO] Group III PH) increases medical costs and reduces survival. Despite limited data, many clinicians are using pulmonary arterial hypertension (PAH)-specific therapy to treat WHO Group III PH patients. To further investigate the utility of PAH-specific therapy in WHO Group III PH, we performed a systematic review and meta-analysis. Relevant studies from January 2000 through May 2016 were identified in the MEDLINE, EMBASE, and COCHRANE electronic databases and www...

The seasonal variability of certain non-allergic respiratory diseases is not clearly understood. Analysis of the breath condensate, the liquid that can be collected by breathing into a cold tube, has been proposed to bring closer to the understanding of airway pathologies. It has been assumed, that (1) airway lining fluid was a stable body liquid and (2) the breath condensate samples were representative of the airway lining fluid. Research was focussed on the identification of biomarkers indicative of respiratory pathologies...

BACKGROUND AND OBJECTIVE: Dietary beetroot juice (BR) supplementation has been shown to reduce the oxygen (O2) consumption of standardized exercise and reduce resting blood pressure (BP) in healthy individuals. However, the physiological response of BR in chronic obstructive pulmonary disease (COPD) remains controversial. The objective was to test exercise performance in COPD, supplementing with higher doses of BR for a longer duration compared to previous trials in this patient group...

BACKGROUND: An increased ventilatory response to exertional metabolic demand (high ventilation (⩒E)-carbon dioxide output (⩒CO2) relationship) is a common finding in patients with coexistent COPD-heart failure. We aimed to determine the mechanisms underlying high ⩒E-⩒CO2 and its impact on operating lung volumes, dyspnea and exercise tolerance in these patients. METHODS: Twenty-two ex-smokers with combined COPD and heart failure with reduced left ventricular ejection fraction (LVEF) undertook, after careful treatment optimization, a progressive cycle exercise test with capillary (c) blood gas collection...

OBJECTIVE: Test the feasibility and clinical outcomes of a home-based videoconferencing yoga intervention in participants diagnosed with both Chronic Obstructive Pulmonary Disease (COPD) and heart failure (HF). BACKGROUND: Yoga has potential benefit for symptom relief in participants with COPD and with HF; however, functional impairment and transportation issues can hinder access to typical yoga classes. METHODS: A controlled, nonrandomized trial was conducted of an 8-week TeleYoga intervention versus an educational control (information leaflets mailed to participants with one weekly phone call)...

Chronic respiratory failure, which is often caused by chronic obstructive pulmonary disease, chronic lower respiratory tract infection, or interstitial pneumonia, often leads to cachexia with disease progression. Patients who have chronic respiratory failure with cachexia exhibit increased morbidity. Although cachectic status is an important clinical problem, there are no effective therapies for cachexia. Ghrelin has various effects, including increasing food intake, attenuating sympathetic nerve activity, inhibiting inflammation, increasing cardiac output, and controlling fat utilization...

PURPOSE OF REVIEW: Supplemental oxygen improves survival in patients with chronic obstructive pulmonary disease (COPD) and severe hypoxaemia, but the effect of oxygen therapy in mild or moderate hypoxaemia to reduce symptomatic chronic breathlessness remains unclear. This review provides an overview of recent evidence about the role of oxygen therapy for the relief of chronic breathlessness in advanced illness. RECENT FINDINGS: In COPD, a recent Cochrane review strengthens earlier findings regarding the positive effect of supplemental oxygen compared with air during exercise test in the training setting...

This study investigated whether different breathing conditions during exercise testing will influence measures of exercise capacity commonly used for training prescription in chronic obstructive pulmonary disease. Twenty-seven patients with chronic obstructive pulmonary disease (forced expiratory volume in 1 sec = 45.6 [9.4]%) performed three maximal exercise tests within 8 days, but at least 48 hrs apart. Subjects were thereby breathing either room air through a tightly fitting face mask like during any cardiopulmonary exercise test (MASK), room air without mask (No-MASK), or 10 l/min of oxygen via nasal cannula (No-MASK + O2)...

Chronic obstructive pulmonary disease (COPD) still remains a serious public health problem, which is a common cause of disability and death in the able-bodied population. Furthermore, the number of patients with metabolic syndrome (MS) is steadily increasing worldwide. Recently, there is also an increase in the number of patients with COPD concurrent with MS, which is a mutually confounding risk factor for concomitant cardiovascular disease and adversely affects prognosis in these patients. Systemic subclinical inflammation is a common link between COPD and the components of MS...

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a major cause of disability and hospital admission. Current management strategies have not been successful in altering the loss of lung function typically seen as the disease progresses. A recent systematic review into the use of spinal manipulative therapy (SMT) in the management of COPD concluded that there was low level evidence to support the view that a combination of SMT and exercise had the potential to improve lung function more than exercise alone in people with moderate to severe COPD...

INTRODUCTION: Chronic obstructive pulmonary disease (COPD) is frequently associated with a reduced functional exercise performance. Even if this parameter is routinely evaluated using 6-minute walking test (6MWT), new field tests are regularly investigated as alternative tests. The aim of this study was to compare functional exercise performance evaluation by sit-to-stand test (STST) and 6MWT and to evaluate reliability and repeatability of the STST in COPD patients. METHOD: Forty-two COPD patients performed randomly two tests: 6MWT and STST...

Chronic obstructive pulmonary disease (COPD) is one of the major causes of chronic morbidity and mortality worldwide. The development of markers of COPD onset is hampered by the lack of accessibility to the primary target tissue, and there is a need to consider other sample sources as surrogates for biomarker research. Airborne toxicants pass through the nasal epithelium before reaching the lower airways, and the similarity with bronchial histology makes it an attractive surrogate for lower airways. In this work, we describe the transcriptomics findings from the nasal epithelia of subjects enrolled in a clinical study focusing on the identification of COPD biomarkers...
