Pulmonary DiseaseChronic Obstructive2 more

The purpose of this study is to determine whether the lungs of individuals with chronic obstructive pulmonary disease (COPD) contain resident memory T lymphocytes that can produce a combination of cytokines that induce the symptoms of an acute exacerbation of COPD (AE-COPD). Specifically, the study will determine cell-surface receptors of lung T cells in comparison with blood T cells from the same subject, and will examine anti-CD3-activated blood or lung T cells for interleukin (IL)-6 and interferon-gamma production in response to IL-18, and for IL-17A production in response to recombinant IL-23.

Retrospective Evaluation of COPD Patient Care

Chronic Obstructive Pulmonary Disease

The purpose of this project is to evaluate hospital utilisation, patient and service outcomes of a Respiratory Nursing Service to examine current clinical care of COPD. This evaluation aims to identify the important gaps in current clinical care of respiratory chronic disease nursing management. The primary outcomes of this evaluation is to determine the efficacy of clinical care in 2006, 2011, 2013 and 2015 and compare data to current Nursing Best practice guidelines for COPD through the quantification of hospital utilisation for hospital admission, average length of stay, readmission within 28 days, emergency service attendance, outpatient review, use of Hospital and Home (H@H), frequency of exacerbations, disease severity and progression (FEV1: GOLD Classification), number of contacts with the respiratory nursing service and type of contacts with the respiratory nursing service.

Systematic Approach for the Diagnosis and Treatment of Obstructive Lung Diseases

Chronic Obstructive Pulmonary DiseaseAsthma1 more

The differential diagnosis of asthma and COPD is sometimes difficult. Recently, an overlap syndrome has been defined based on the concurrence of asthma and COPD characteristics. These characteristics are based on expert opinions and have never been investigated nor validated prospectively. The investigators assume that the management strategy, the symptom burden and disease progression will differ between asthma, COPD and ACOS. Therefore, the study wants to establish baseline criteria for an appropriate disease definition and evaluate the potential impact on treatment and symptom control.

The Early Predictors for Developing Type 2 Diabetes Mellitus in Patients With Chronic Obstructive...

Chronic Obstructive Pulmonary DiseaseType 2 Diabetes Mellitus

Chronic obstructive pulmonary disease(COPD), characterized by persistent airflow limitation, associated with an progressive chronic inflammatory response of the lung to noxious particles or gases, can lead to dyspnea and limited mobility and influence the life quality of patients severely. Type 2 diabetes mellitus(T2DM), as a common complication of COPD, has got more attention in comprehensive control of COPD. Stress response and metabolic disorder are more likely to happen in COPD patients with T2DM in high level inflammation status, which decrease the drug efficacy, increase the risk of acute exacerbation of COPD, complications and mortality. Both COPD and T2DM are chronic inflammatory disease with long term, there is close relationship in occurrence and development of each other, and the patients with severe COPD are more likely to develop T2DM. Monitoring the acute inflammation maker of C reactive protein (CRP) and IL-6(interleukin-6) is the most useable way to predict the inflammatory status and condition of COPD patient with T2DM, however the chronic inflammation maker is lacking. Neutrophil-to-Lymphocyte ratio(NLR), platelet-lymphocyte ratio (PLR) and lymphocyte-monocyte ratio (LMR) , the new, cheap and easy-tested chronic inflammatory markers, have got great research in early predicting the tumor such as nasopharyngeal carcinoma, soft tissue sarcoma and small-cell lung cancer,among them, NLR has manifest promising application in predicting insulin-resistance. However the value about NLR,PLR and LMR to predict the T2DM in COPD patients remain unknown and many articles related to NLR and COPD are retrospective. The investigators attempt to analyze the risk factors and predict value of NLR,PLR and LMR about developing T2DM in COPD patients with prospective method.

A Wireless Bed Sensor for Monitoring Coughs

Chronic Obstructive Pulmonary DiseaseRespiratory Disease

Aging of the population is dramatically increasing the number of hospitalized patients, with the consequent challenges of limited medical personnel and resources in hospitals. Wireless technologies that create highly connected healthcare environments are developed to help hospitals address these issues, once these technologies are perfectly integrated in the hospital environment with respect to IT infrastructure for big data storage. Such devices have proven remarkable efficiencies in monitoring patients with high patient safety, data accuracy and security, which are essential to provide high quality patient care, reduce health-related costs and optimize the management of high numbers of patients. Cough is the most common condition that results in a visit to the physician. Often coughs are benign, but sometimes can be the sign of exacerbations of a chronic respiratory disease. Exacerbations are defined in the Global Initiative for Chronic Obstructive Lung Disease (GOLD) document "as an acute event characterised by a worsening of the patient's respiratory symptoms that is beyond normal day-to-day variations and leads to a change in medication". It is assumed that, if coughs were remotely monitored, hospitals might be unburdened, patients would be empowered to self-manage their health, and that prevention of serious respiratory diseases might be facilitated, thus improving health outcomes. Unfortunately, remote monitoring for cough that rely on self-reporting is impractical, as patients do not record data very reliably. On the contrary, a bed sensor under the mattress connected to a medical data analysis platform might monitor patients' micro-movements at night and alert the medical staff as soon as there is a cough exacerbation.

HomeVent ( Connect) Registry: EU COPD Home NIV Registry

Chronic Obstructive Pulmonary Disease

The prevalence of chronic respiratory disease, including chronic obstructive pulmonary disease (COPD), is increasing in industrialized countries. Over the next decade deaths from COPD are projected to increase by more than 30% and COPD will become the third leading cause of death worldwide by 2030. There is robust scientific evidence that non-invasive ventilation (NIV) therapy is an effective option for most COPD patients hospitalized with acute hypercapnic respiratory failure secondary to an acute disease exacerbation. More recently, NIV has been shown to significantly improve survival and quality of life in COPD patients with chronic stable hypercapnic disease. These data represent an important advance in the field, and indicate that usage of NIV in patients with chronic stable hypercapnic COPD should increase. Such an increase would be expected to improve patient outcomes and have a beneficial impact on the significant healthcare burden incurred by these patients. However, the proportion of stable COPD patients with chronic hypercapnia is unknown. In addition, using NIV at home to treat COPD patients with hypercapnic (type 2) respiratory failure has not often been considered previously and there is a paucity of data regarding NIV usage patterns over time in this setting. Phase2: There is robust scientific evidence that non-invasive ventilation (NIV) therapy is an effective option for most COPD patients hospitalised with acute hypercapnic respiratory failure secondary to an acute disease exacerbation [3]. More recently, NIV has been shown to significantly improve survival and quality of life in COPD patients with chronic stable hypercapnic disease [4] and in patients with persistent hypercapnia after an acute chronic respiratory failure [11]. Over the past two decades, the utilisation of NIV has become one of the most important developments in the field of mechanical ventilation. However, unsuccessful NIV was found to be independently associated with death [5] and poor NIV compliance was associated with higher risk of repeat acute NIV use [6]. There is a paucity of useful predictors of poor patient compliance and the performance of conventional algorithms for detecting COPD exacerbations is still weak. Detection of NIV failure is crucial in patient management in view of its negative effect on quality of life and prognosis and the fact that it often leads to hospitalisation. In addition, 70% of COPD-related healthcare costs are consequences of emergency and hospital stays for the treatment of exacerbations [7]. Recently, tele-monitoring emerged and unfolded differently among various healthcare organisations and countries. Evidence regarding its impact on the management of COPD patients is still insufficient to draw firm conclusions. Assumption has been made that remote monitoring of home NIV treatment could help to identify novel predictors of the early detection of NIV failure and deteriorations in patients with COPD. The incidence in routine clinical care of unplanned all-cause and COPD-caused hospitalisations in patients treated with NIV therapy who are continuously monitored by telemetric data in several European countries needs evaluation. In addition, predictors of unplanned all-cause and COPD-caused hospitalisations as well as of compliance and persistence to NIV therapy should be assessed in this patient population with special respect to continuous tele-monitoring
