Inhaled, long-acting anticholinergic medication (LAA), commonly used for moderate-to-severe chronic obstructive pulmonary disease (COPD), has been shown to decrease COPD hospitalizations, emergency department visits, and acute exacerbations but has also been associated with urinary tract infection (UTI) in a prior meta-analysis. The objective of this study was to verify if there was an association between LAA and UTI in older individuals with COPD. A population-based, real-world cohort study using health administrative data from Ontario, Canada was conducted...

In severe COPD, patients having survived acute hypercapnic respiratory failure (AHRF) treated with noninvasive ventilation (NIV) have a high mortality and risk of readmissions. The aim was to analyze the prognosis for patients with COPD having survived AHRF and to assess whether previous admissions with NIV predict new ones.We conducted a retrospective follow-up analysis of 201 patients two years after NIV treatment of AHRF. Comparison of time-to-event in patients previously treated with NIV versus patients with no previous NIV treatment...

The new A-B-C-D Global Initiative for Chronic Obstructive Lung Disease (GOLD) classification of severity of chronic obstructive pulmonary disease (COPD) is based on combined symptoms and exacerbation risk assessment. The assumed equivalence between dyspnoea modified Medical Research Council (mMRC) grade ≥2 and COPD Assessment Test (CAT) score ≥ 10 to identify more symptoms has been questioned. Whether the exacerbation risk assessment criteria, old GOLD spirometry staging and frequency of exacerbations, are equivalent has not been examined...

It is unclear whether concurrent pneumonia and chronic obstructive pulmonary disease (COPD) have a higher mortality than either condition alone. Further, it is unknown how this interaction changes over time. We explored the effect of pneumonia and COPD on inpatient, 30-day and overall mortality. We used a Veterans Health Affairs database to compare patients who were hospitalized for a COPD exacerbation without pneumonia (AECOPD), patients hospitalized for pneumonia without COPD (PNA) and patients hospitalized for pneumonia who had a concurrent diagnosis of COPD (PCOPD)...

Ageing is defined as a progressive decline of homeostasis that occurs after the reproductive phase of life is complete, which is thought to arise because of impaired DNA repair following damage. This leads to an increased risk of disease or death. Ageing is one of the most important risk factors for most chronic diseases. Chronic obstructive pulmonary disease (COPD) represents an important component of the increasingly prevalent multiple chronic debilitating diseases that are a major cause of morbidity and mortality, particularly in the elderly...

A systematic literature review was performed to identify all peer-reviewed literature quantifying the association between short-term exposures of particulate matter <2.5 microns (PM2.5), nitrogen dioxide (NO2), and sulfur dioxide (SO2) and COPD-related emergency department (ED) visits, hospital admissions (HA), and mortality. These results were then pooled for each pollutant through meta-analyses with a random effects model. Subgroup meta-analyses were explored to study the effects of selected lag/averaging times and health outcomes...

Inhaled indacaterol/glycopyrronium fixed-dose combination (IND/GLY) is approved in over 80 countries, including the EU, Japan, Australia and Switzerland and the US. The LANTERN study evaluated the efficacy of IND/GLY compared with inhaled long-acting β2-agonist (LABA)/inhaled corticosteroid (ICS) or salmeterol/fluticasone (SFC) in patients with moderate-to-severe COPD with a history of ≤1 exacerbation in the previous year. Here we present the efficacy and safety of IND/GLY versus SFC in the Chinese cohort from the LANTERN study...

The objective of this study was to determine whether an exercise intervention using a pedal exerciser is able to reduce disability in frail older patients with chronic obstructive pulmonary disease (COPD) during hospitalization due to an acute exacerbation. This study was a randomized, single-blind clinical trial. Fifty-eight frail older patients admitted to hospital due to an acute exacerbation of COPD (AECOPD) were included in this study. All patients received standard medical and pharmacological care. Patients assigned to the intervention group also received an exercise intervention...

Oxidative stress, inflammation, increased bronchial epithelial cell apoptosis, and deficient phagocytic clearance of these cells (efferocytosis) by the alveolar macrophages are present in chronic obstructive pulmonary disease (COPD) and in response to cigarette smoke. We previously showed that the macrophage dysfunction is associated with changes to the sphingosine-1-phosphate (S1P) signalling system. We hypothesized that the antioxidant/anti-inflammatory agent, thymoquinone, would improve macrophage phagocytosis via modulation of the S1P system and protect bronchial epithelial cells from cigarette smoke or lipopolysaccharide (LPS)-induced apoptosis...

Chronic obstructive pulmonary disease (COPD) is a complex and multifactorial disease with a strong genetic component. Our objective is to identify the genetic variants associated with COPD risk and its severity in Mexican Mestizo population. We evaluated 1285 single-nucleotide polymorphisms (SNPs) of candidate genes in 299 smokers with COPD (COPD-S) and 531 smokers without COPD (SWOC) using an Illumina GoldenGate genotyping microarray. In addition, 251 ancestry informative markers were included. Allele A of rs2545771 in CYP2F2P is associated with a lower risk of COPD (p = 4...

Discussion about patients' end-of-life (E-o-L) preferences should be part of the routine practice. Using a semi-structured interview with a scenario-based decision, we performed a prospective multicentre study to elicit the patients' E-o-L preferences in very severe chronic obstructive pulmonary disease (COPD). We also checked their ability to retain this information and the respect of their decisions when they die. Forty-three out of ninety-one of the eligible patients completed the study. The choice of E-o-L practice was equally distributed among the three proposed options: endotracheal intubation (ETI), 'ceiling' non-invasive ventilation (NIV), and palliation of symptoms with oxygen and morphine...

The chronic course and evolution of chronic obstructive pulmonary disease (COPD) is often characterized by periods of exacerbation of symptoms, which have a negative impact on the quality of life of patients, as well as on the evolution of COPD, and represent a significant cause of medical intervention and hospitalization. Very few data are available on the efficacy of rescue antibiotics in patients with acute exacerbation of COPD (AECOPD) unresponsive to previous treatment. The aim of this study was to evaluate the efficacy of two fluoroquinolones in AECOPD previously treated without success...

UNLABELLED: The evidence for tele-assistance (TA) in hypercapnic chronic obstructive pulmonary disease (COPD) patients on long-term oxygen therapy (LTOT) is scarce. The aim of this study was to evaluate the effects of addition of long-term TA to LTOT with or without non-invasive ventilation (NIV) in these patients. Retrospective analysis of a previous randomised study of patients on LTOT. According to the care programme patients were divided into Group 1: LTOT; Group 2: LTOT + NIV; Group 3: LTOT + TA and Group 4: LTOT + NIV+TA...

Interleukin-32 (IL-32) is a newly described cytokine which is expected to have an important role in autoimmune disorders. It was shown that chronic obstructive pulmonary disease (COPD) has a component of autoimmunity, though the role of IL-32 in its pathogenesis is not known. The aim of this study was to estimate IL-32 concentrations in serum, induced sputum (IS) supernatant and bronchoalveolar lavage (BAL) fluid from patients with COPD, and to compare asthma patients with and healthy subjects. Outpatients with COPD (63...

The aim of this study was to assess the changes in muscle fiber conduction velocity (CV), as a sign of fatigue during knee extensor contraction in patients with chronic obstructive pulmonary disease (COPD) as compared with healthy controls. Eleven male patients (5 with severe and 6 with moderate COPD; age 67 ± 5 years) and 11 age-matched healthy male controls (age 65 ± 4 years) volunteered for the study. CV was obtained by multichannel surface electromyography (EMG) from the vastus lateralis (VL) and medialis (VM) of the quadriceps muscle during isometric, 30-second duration knee extension at 70% of maximal voluntary contraction...

This observational study assessed the relationship between nighttime, early-morning and daytime chronic obstructive pulmonary disease (COPD) symptoms and exacerbations and healthcare resource use. COPD symptoms were assessed at baseline in patients with stable COPD using a standardised questionnaire during routine clinical visits. Information was recorded on exacerbations and healthcare resource use during the year before baseline and during a 6-month follow-up period. The main objective of the analysis was to determine the predictive nature of current symptoms for future exacerbations and healthcare resource use...

Caregivers of individuals with chronic obstructive pulmonary disease (COPD) experience significant burden. To develop effective interventions to support this vulnerable group, it is necessary to understand how this burden varies as a function of patient well-being and across the illness trajectory. This systematic review aimed to identify the number and type of data-based publications exploring the burden and unmet needs of caregivers of individuals with COPD. Medline, Embase, PsycINFO and Cochrane databases were searched for studies published between January 2000 and February 2014...

The smoking habit is accompanied by an acute inflammatory response which follows tissue injury. It would be desirable to find a non-invasive inflammatory marker that would simplify the task of studying and monitoring smokers more simply and allow us to identify populations at risk of contracting Chronic Obstructive Pulmonary Disease (COPD). Today's expectations regarding research focus on issues ranging from inflammatory markers to those of exhaled breath temperature (EBT) are considerable. That said, although the EBT has been largely studied in asthma and COPD, there have not been any studies thus far that have analysed the effect of cigarette smoking on the EBT...
