Filter by:In patients with Chronic Obstructive Pulmonary Disease (COPD) lifestyles with lower physical activity levels have been shown to increase the risk of hospital admissions and shorten survival rates. An established process in increasing activity levels is to undergo pulmonary rehabilitation classes. The investigators wish to identify whether the use of activity monitors,which will provide feedback on activity levels, will increase the physical activity levels of patients with COPD outside of the supervised pulmonary rehabilitation sessions.
This study evaluates the local and systemic inflammatory response in the airway in COPD patients who consume electronic cigarettes compared with conventional cigarette smokers.
The study is to compare the effectiveness of two health communication and dissemination strategies that are designed to engage patients and family caregivers in successfully managing COPD in 'real-world' settings. Both strategies aim to advance patient understanding of COPD, its treatment options, and self-care tasks; support them in coping with the disease; and enable them to adopt a variety of positive behaviors, including adherence to treatment plans, smoking cessation, joining pulmonary rehabilitation programs, and assuming an active, healthy lifestyle. One strategy relies on the healthcare professional (HCP) as the primary communicator about COPD self-management (HCP arm), whereas the other uses a dual approach that involves both healthcare professionals and peer mentors delivering such communication (HCP plus Peer arm). Peer mentors are COPD patients and caregivers who have successfully managed COPD and have received foundational training on peer mentoring. Specifically, the study aims are to : 1) Conduct a randomized controlled trial in which the 'HCP' and 'HCP plus Peer' strategies are tested in 'real-world' healthcare settings; 2) compare the impact of these strategies on patient satisfaction, experience, activation, self- efficacy, self-care behavior, health status, quality of life, use of Emergency Department (ED) and hospital services, and survival; and, 3) compare the impact of these strategies on caregiver satisfaction, experience, self-efficacy, stress, and coping skills.
The purpose is to study the correlation between systemic inflammation (serum levels of CRP, IL-1beta, IL-6 and TNF-alpha) or hyperhomocysteinemia and the increase of mortality, in a representative cohort of patients with chronic obstructive pulmonary disease (COPD). Secondary purposes are: 1. To confirm the increase of cardiovascular mortality and the importance of cardiovascular morbidity in patients with COPD, 2. To establish the role of various genetic polymorphisms in the correlation between systemic inflammation and cardiovascular disorders observed in COPD, 3. To search for acceleration of aging of cardiovascular system evaluated with carotid intima-media thickness when systemic inflammation markers are increased, 4. To study the correlation between COPD risk factors (tobacco and other food factors), change of respiratory functional data and cardiovascular morbi-mortality. In this study cardiovascular morbi-mortality is defined by following disorders: ischemic cardiopathy, left-sided heart failure, cardiac arrhythmia and cerebrovascular accident. Diagnosis is confirmed with standard techniques and independently of this study. Results of clinical examination, ECG, echocardiography and /or brain scanner will be collected.
This study will prove to concept of effectiveness of NHF in combination with a nebulizer on reversibility of lung function in COPD patients.
Chronic Obstructive Pulmonary Disease (COPD) is a condition resulting from environmentally induced lung damage e.g. cigarette smoking and air pollution which, over time, causes individuals to suffer from symptoms including chronic cough and progressive breathlessness. In the UK COPD is predominantly caused by cigarette smoking which may have occurred decades before the symptoms appear and the disease is diagnosed. The aim of this study is to identify those COPD patients who currently have milder disease and to investigate whether a detailed, medical assessment which has time to assess all aspects of their care will improve their lung health and general wellbeing. COPD is a major cause of disability and death in the UK, with around 835,000 people currently diagnosed with the disease and an estimated further two million people who suffer from symptoms but do not yet have a diagnosis(1). Approximately 25,000 people each year die from COPD in England and Wales (2), with the disease accounting for 5.4% of all deaths in England and Wales in 2013 (3). Predominantly in its later, more severe stages, COPD causes an enormous symptom burden to patients, and accounts for up to half of emergency admissions to already overstretched hospital services in England (4). People with COPD, with a past history of smoking, are at higher risk of other medical problems such as heart disease and stroke(5). Being breathless and having multiple physical health problems can also lead to mental health problems such as anxiety and depression(5). This means it can be challenging to provide this group of people enough time to fully assess and treat all their problems, particularly due to current pressure on the length of GP appointment times. Whilst COPD is treatable, it is not curable, and emphasis on early diagnosis and intervention provided a key part of the strategy for COPD published by NHS England in 2012(6). With early diagnosis, the opportunity is provided to intervene with the aim of improving symptoms and exercise tolerance, reducing the risk of exacerbations, slowing deterioration and prolonging quality of life.
The clinical course of chronic obstructive pulmonary disease (COPD) is associated with recurrent episodes of exacerbation that results in respiratory failure. The treatment of respiratory failure is supportive and involves inhalation bronchodilators along with systemic steroids. In few cases the management of acute respiratory failure requires positive pressure ventilation (non-invasive or invasive). The use of NIV in acute exacerbation of COPD has resulted in significant reduction in morbidity and mortality. Although pressure support ventilation (PSV) allows the patient to influence the breathing pattern, ventilator-cycling criteria may worsen the patient-ventilator interaction, and severe asynchronies occur in up to 43% of patients undergoing NIV for ARF. Adaptive support ventilation (ASV) is a newer mode of ventilation that incorporates feedback mechanisms and thus provides a stable minute ventilation. We hypothesize that the use of ASV as a mode during ventilation using NIV in patients with acute exacerbation of COPD may result in reducing the duration of ventilatory support, need for intubation, and duration of intensive care unit (ICU) and hospital length of stay, when compared with PSV mode of NIV ventilation.
In this study, 20 hypercapnic COPD patients will perform two constant workrate endurance cycle tests. One test will be while using non-invasive Ventilation (NIV) support, one without in a randomized cross-over design. The aim is to measure, whether NIV is able to change peripheral and respiratory muscle oxygenation.
The primary cause of chronic obstructive pulmonary disease is smoking, which can lead to inflammation in the lungs and blood vessels that can lead to secondary problems such as blood vessel disease, high blood pressure and heart disease. Aerobic exercise training has been shown to reduce the risk of heart and brain disease; however, it is currently unknown whether exercise training can have the same affect in patients with COPD. The aim of this study is to investigate how eight weeks of aerobic exercise training improves blood vessel and heart function and brain blood flow in patients with COPD.
Airway epithelium integrity is essential to maintain its role of mechanical and functional barrier. Recurrent epithelial injuries require a complex mechanism of repair to restore its integrity. In chronic obstructive pulmonary disease (COPD), an abnormal airway epithelial repair may participate in airway remodelling. The objective was to determine if airway epithelial wound repair of airway epithelium is abnormal in COPD.
