BACKGROUND: There are an estimated three million people in the United Kingdom with chronic obstructive pulmonary disease (COPD), and the incidence of bronchiectasis is estimated at around 0.1% but is more common in COPD and severe asthma. Both COPD and bronchiectasis are characterized by exacerbations in which bacteria play a central role. Pseudomonas aeruginosa is isolated from sputum samples from 4% to 15% of adults with COPD and is more likely to be isolated from patients with severe disease...

INTRODUCTION: Replacing sedentary behaviour with light intensity physical activity (ie, activities classified as less than three metabolic equivalents, such as slow-paced walking) may be a more realistic strategy for reducing cardiometabolic risk in people with chronic obstructive pulmonary disease than only aiming to increase levels of moderate-vigorous intensity physical activity. Behaviour change interventions to reduce sedentary behaviour in people with chronic obstructive pulmonary disease have not yet been developed or tested...

Asthma and chronic obstructive pulmonary disease (COPD) are common chronic respiratory diseases. Both diseases have incompletely distinct pathophysiology, clinical manifestation, and treatment responsiveness. Pulmonary and systemic inflammations are the hallmarks of COPD. Most asthma responds to inhaled corticosteroid (ICS) treatment. In contrast, COPD is a corticosteroid-resistant disease. Bronchodilators are a preferred treatment method of COPD, with the aim of improving symptoms and preventing exacerbation...

Chronic obstructive pulmonary disease (COPD) kills more than 3 million people worldwide every year. Despite progress in the treatment of symptoms and prevention of acute exacerbations, few advances have been made to ameliorate disease progression or affect mortality. A better understanding of the complex disease mechanisms resulting in COPD is needed. Smoking cessation programmes, increasing physical activity, and early detection and treatment of comorbidities are further key components to reduce the burden of the disease...

This study aimed to investigate computer and internet access and education attained in patients with chronic obstructive pulmonary disease (COPD) as potential barriers to implementation of telemedicine. We prospectively assessed 98 patients admitted with an acute exacerbation of COPD (mean age: 70.5 ± 9.3 years; force expired volume in the first second: 0.75 ± 0.39 L; 59% male) recording educational level attained and home computer and internet access. Hospital readmission surveillance occurred up to 2.7 (2...

Takotsubo cardiomyopathy (TCM) is a variant of stress-induced cardiomyopathy, characterized by transient left ventricular dysfunction that may be associated with emotional or physical triggers. We present the case of a 51-year-old Caucasian female with severe chronic obstructive pulmonary disease (COPD) who presented with syncope and was found to have her second lifetime episode of stress-induced cardiomyopathy. Eight months prior, she had been admitted with a COPD exacerbation and was found to have left ventricular (LV) dysfunction with ejection fraction (EF) of 22% attributed to TCM with subsequent normalization of her left ventricular function...

BACKGROUND: Neutrophil extracellular traps (NETs) have been observed in the airway in COPD, but their clinical and pathophysiological implications have not been defined. OBJECTIVE: To determine if NETs are associated with disease severity in COPD, and how they are associated with microbiota composition and airway neutrophil function. METHODS: NET protein complexes (DNA-Elastase and Histone-Elastase complexes), cell free DNA and neutrophil biomarkers were quantified in soluble sputum and serum from COPD patients during periods of disease stability and during exacerbations, and compared to clinical measures of disease severity and sputum microbiome...

INTRODUCTION: The aim of extracorporeal removal of CO2 (ECCO2R) is to ensure the removal of CO2 without any significant effect on oxygenation. ECCO2R makes use of low to moderate extracorporeal blood flow rates, whereas extracorporeal membrane oxygenation (ECMO) requires high blood flows. STATE OF THE ART: For each ECCO2R device it is important to consider not only performance in terms of CO2 removal, but also cost and safety, including the incidence of hemolysis and of hemorrhagic and thrombotic complications...

The key pathophysiological feature of chronic obstructive pulmonary disease (COPD) is an abnormal inflammatory bronchial reaction after inhalation of toxic substances. The priority is the avoidance of such toxic inhalations, but the use of anti-inflammatory drugs also seems appropriate, especially corticosteroids that are the sole anti-inflammatory drug available for this purpose in France. The risks associated with the prolonged use of these parenteral drugs are well known. Inhalation is therefore the optimal route, but inhaled drugs may also lead to adverse consequences...

BACKGROUND: The protein deacetylase sirtuin-1 (SIRT1) is an anti-aging molecule that is decreased in the lung from patients with chronic obstructive pulmonary disease (COPD). Recently, SIRT1 was reported to be detectable in serum, but serum SIRT1 levels have not yet been reported in patients with COPD. METHODS: Serum SIRT1 was measured by Western blotting, and relative ratio of band density in samples against that of a positive control were calculated. RESULTS: Several molecular sizes of SIRT1, including 120kDa (actual size) and fragments (102, 75kDa) were quantified by Western blotting...

Chronic respiratory failure due to chronic obstructive pulmonary disease (COPD) is an increasing problem worldwide. Many patients with severe COPD develop hypoxemic respiratory failure during the natural progression of disease. Long-term oxygen therapy (LTOT) is a well-established supportive treatment for COPD and has been shown to improve survival in patients who develop chronic hypoxemic respiratory failure. The degree of hypoxemia is severe when partial pressure of oxygen in arterial blood (PaO2) is ≤55 mmHg and moderate if PaO2 is between 56 and 69 mmHg...

Acute worsenings of chronic obstructive pulmonary disease (COPD) were for a long time regarded as transient deteriorations, although occasionally life-threatening. No connection to disease progression was recognized. Data emerging during the last decade showed that patients had a considerably worse survival outcome after severe exacerbations. This insight was consolidated in 2012 by a large population-based cohort analysis. At present, severe exacerbations are regarded as key risk factors for COPD disease progression...

Asthma and chronic obstructive pulmonary disease (COPD) are considered as two distinct obstructive diseases. Both chronic diseases share a component of airway epithelial dysfunction. The airway epithelium is localized to deal with inhaled substances, and functions as a barrier preventing penetration of such substances into the body. In addition, the epithelium is involved in the regulation of both innate and adaptive immune responses following inhalation of particles, allergens and pathogens. Through triggering and inducing immune responses, airway epithelial cells contribute to the pathogenesis of both asthma and COPD...

BACKGROUND: The need for additional research on symptomatic smokers with normal spirometry has been recently emphasized. Albeit not meeting criteria for Chronic obstructive pulmonary disease (COPD) diagnosis, symptomatic smokers may experience activity limitation, evidence of airway disease, and exacerbations. We, therefore, evaluated whether symptomatic smokers with borderline spirometry (post-bronchodilator FEV1/FVC ratio between 5th to 20th percentile of predicted values) have pulmonary function abnormalities at rest and ventilatory constraints during exercise...

It is hypothesized that systematic oral hygiene may reduce airway infections in patients with chronic obstructive pulmonary disease (COPD). Before considering doing a systematic review, a scoping review is necessary to explore and map literature on the subject and identify which interventions have been carried out, if there is relevant literature available for a systematic review, or if further research should be initiated.The objective of this scoping review is to comprehensively identify and describe qualitative or quantitative literature reporting of non-invasive interventions that have been carried out to improve oral hygiene and relieve and/or reduce respiratory tract infections, exacerbation and/or hospital readmission in patients with diagnosed with COPD...

BACKGROUND: Alpha-1 antitrypsin deficiency (AATD) is a rare genetic condition predisposing individuals to chronic obstructive pulmonary disease (COPD). The treatment is generally extrapolated from COPD unrelated to AATD; however, most COPD trials exclude AATD patients; thus, this study sought to systematically review AATD-specific literature to assist evidence-based patient management. METHODS: Standard review methodology was used with meta-analysis and narrative synthesis (PROSPERO-CRD42015019354)...
