Filter by:COPD is characterized by lung injury and inflammation caused by noxious particles and gases, including those emanating from cigarette smoke and air pollution. Despite the clear detrimental impact of poor air quality on respiratory outcomes, regardless of smoking status, to investigators' knowledge, there are no studied environmental interventions targeting indoor air quality to improve respiratory health of smokers, thus ignoring a potential target for harm reduction. Investigators propose a randomized controlled intervention trial to test whether targeted reductions of multiple indoor pollutants (PM, SHS and NO2) in homes of smokers with COPD will improve respiratory outcomes. Investigators have chosen a potent, multimodal intervention (active air cleaners + Motivational intervention for SHS reduction) in order to maximize the opportunity to prove that there is a health benefit to active smokers with COPD from indoor air pollution reduction.
Chronic Obstructive Pulmonary Disease (COPD) is a common progressive lung disease which causes breathlessness and frequent exacerbations, with patients often requiring hospitalisation. Patients with severe COPD commonly become housebound and lose their independence. They have a higher symptom burden than those with incurable lung cancer, yet are less likely to receive specialist palliative care, or to have been engaged in advance care planning (where patients discuss and often document their wishes regarding their future care). Hospital admissions become increasingly common towards the end-of-life; therefore, hospitalisation is a good opportunity to identify patients at risk of poor outcome. Such patients may wish to consider alternatives to admission and avoid intrusive treatments. Unfortunately, predicting which patients are likely to die in the near future is challenging thus far. The first step required to improve provision of palliative care services, and ensure patients are given the opportunity to make truly informed decisions about their future care, is accurate identification of those most likely to benefit. Well-designed clinical (prognostic) tools outperform clinician judgement in most settings. The investigators will compare the accuracy of one year mortality prediction of several clinical tools in patients who survive a COPD exacerbation requiring admission. This will initially be performed using existing data collected during previous research (the 1,593 patient validation study for the PEARL score - Previous admissions, extended Medical Research Council Dyspnoea score, Age, Right and Left heart failure), then confirmed in at least 310 patients admitted uniquely and consecutively with an exacerbation of COPD. The latter group of patients will be invited to participate in a longitudinal follow-up study, assessing symptom burden, quality of life, and readmissions over one year.
This study will investigate the effects of positive expiratory pressure (PEP) on hyperinflation in patients with chronic obstructive pulmonary disease (COPD). Inspiratory capacity (IC) is the primary outcome
The aim of this study is to assess the effectiveness of a home-based exercise training program in COPD patients who did not participate in an inpatient or outpatient rehabilitation program within the last 2 years.
This is a qualitative research exploration engaging clinical staff at all levels from 10 Practice-Based Research Networks (PBRNs) serving US patient populations of differing gender, racial, ethnic, urban/rural and socio-economic blends, in the incorporation of a one-page, five-item questionnaire with selective PEF measurement (CAPTURE).
This project seeks to pilot-test the feasibility of using a melodica training program to teach pursed lip breathing for Veterans with chronic obstructive pulmonary disease (COPD) with moderate to severe dyspnea (shortness of breath). Dyspnea occurs commonly among COPD patients and can limit activities of daily living. Pursed lip breathing is a strategy that can improve dyspnea and exercise capacity among COPD patients. The melodica is a musical instrument that looks like a keyboard with a mouthpiece on the side. The melodica is played by exhaling through the mouthpiece while pressing the keys. The MELODY pilot project protocol has been grounded on concepts from occupational therapy; specifically, providing participants with a meaningful new activity that is enjoyable, that can be provided across a spectrum of skill levels, that can provide participants with a new sense of self, and that can improve health outcomes (i.e., dyspnea and exercise endurance).
Chronic obstructive pulmonary disease (COPD) is the 4th leading cause of death worldwide and affects 1.2 million people in the UK, costing the NHS >£800 million annually. COPD patients are more susceptible to bacterial infections and both chronic and acute infections are common. COPD patients with chronic lung bacterial infection have worse quality of life, faster disease progression, more symptoms and frequent exacerbations. Acute infections are the main cause of COPD exacerbations which cause COPD patients to become acutely unwell and often result in hospitalisation especially in the winter. Antibiotics are frequently used to treat COPD exacerbations and this contributes to the development of antibiotic resistance. Therefore there is a need to develop antibiotic-independent approaches to reducing or preventing bacterial infection in COPD. The investigators have carried out work in in animal studies and in humans showing that there is a link between high levels of glucose in the lung and bacterial lung infection. Levels of glucose in the lung are higher in COPD patients compared with people without COPD. These higher glucose levels support greater bacterial growth probably because glucose is a nutrient for bacteria. Therefore reducing airway glucose has the potential to inhibit bacterial growth in COPD patients. In animal studies the investigators have demonstrated that the diabetic drug metformin decreases airway glucose and bacterial growth. The investigators wish to determine if metformin can achieve the same effects in COPD patients. Metformin is safe and cheap, and has been extensively used in COPD patients with diabetes with an excellent safety record. The primary aim of this study will be to determine whether metformin reduces lung glucose in a small group of non-diabetic COPD patients. If it demonstrates that metformin reduces lung glucose concentrations it will justify a larger clinical trial of metformin as a treatment for COPD.
The purpose of this study is to determine whether early diagnosis of OSA and initiation of and adherence to CPAP therapy in patients hospitalized for chronic obstructive pulmonary disease reduce 30-day hospital readmission rates.
A study to evaluate the effects of ACT-541468 on respiration in patients with moderate chronic obstructive pulmonary disease
This is a prospective multicenter cohort study which includes all consecutive COPD patients who come for a visit in one the participating pneumologist. They will have to do a sputum and to complete some questionnaries. Questionnaries will be redone by phone after 1 and 3 months and during the visit after 6 months. We will correlate aspergillus presence in sputum with quality of life (QoL), and COPD symptoms evaluated by questionnaires.
