Active clinical trials for "Lung Diseases, Obstructive"

The primary objective is to investigate the efficacy of resveratrol on mitochondrial function in patients with COPD. The secondary objective is to investigate the effect of resveratrol on body composition, inflammatory status and mechanistic markers in blood, adipose and muscle tissue as well as a comprehensive assessment of metabolicand physical performance profile known to be affected by resveratrol.

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).

The purpose of this protocol is to test the safety, pharmacokinetics, and pharmacodynamics of the Cystic fibrosis transmembrane conductance regulator (CFTR) potentiator, ivacaftor in patients with chronic obstructive pulmonary disease (COPD) and chronic bronchitis. This project will investigate the hypothesis that ivacaftor can augment CFTR activity in individuals with COPD who exhibit chronic bronchitis, resulting in meaningful improvements in epithelial function and respiratory health. The study is a multicenter, randomized, double-blind, placebo-controlled, stratified study of orally-administered ivacaftor.

The SWIFT trial is a cluster randomised trial to determine if a patient identification, feedback and inhaled corticosteroid (ICS) withdrawal intervention in primary care can result in more appropriate inhaled corticosteroid use without increasing the frequency of exacerbations. Practices in Tayside and Fife will be randomised at practice level to an intervention or control. The intervention will consist of electronic review of patients Chronic obstructive pulmonary disease (COPD) data and prescribing history, followed by implementation of a medication change involving withdrawal of ICS and introduction of a Long acting beta adrenergic agonist (LABA) and Long acting muscarinic antagonist (LAMA) for patients without an indication for ongoing ICS treatment. Patients in control practices will not receive the intervention, but practices will be provided with local guidelines and formulary and encouraged to prescribe appropriately. Patients in the control practices may be switched to guideline compliant medications. Our hypothesis is that removal of non-evidence barriers to appropriate prescribing will result in in high rates of ICS withdrawal and that the intervention will be safe, as evidenced by no increase in the frequency of exacerbations over 12 months of follow-up.

The colonization of potential pathogenic bacteria in lower respiratory tract is thought to be accountable for acute exacerbation in subjects with moderate to severe COPD. However, there is no accepted therapy for patients with COPD to remove the colonized bacteria in lower respiratory tract. Therefore, we plan to perform a multi-center, randomized, controlled trial to study the efficacy and safety of oral probiotics, aerosol inhaled amikacin or combined vaccination to decolonize bacteria in lower respiratory tract and prevent acute exacerbation of COPD.

Background: Informative and supportive nursing care is essential to reduce complications and improve outcomes in Chronic Obstructive Pulmonary Disease (COPD) patients treated with Non-Invasive Ventilation (NIV). Objective: Aim of the study is to determine the effect of provision of information and supportive nursing care on blood gas, vital signs, anxiety, stress and agitation levels in COPD patients treated with NIV. Research Methodology: A randomised controlled design was used between September-December 2019. The universe of the study consisted of COPD patients treated with NIV in intensive care unit in a state hospital. A total of 60 patients, composed of 30 interventions and 30 controls, were randomly included in the sample. Provision of information and supportive nursing care was applied to the patients in the intervention group. The data were evaluated with SPSS program. Results: Following the intervention, the findings showed that the provision of information and supportive nursing care has a positive effect on the blood gas, vital signs, anxiety, stress and agitation levels of patients. Conclusions: The provision of information and supportive nursing care is recommended to alleviate anxiety, stress and agitation in COPD patients treated with NIV

This project plans on a training intervention by using public spaces and urban walkable trails, adapted to each patient needs and capabilities. Primary objective is to assess 12 months effectiveness of the intervention with respect to: (primary outcome): physical activity level, and (secondary outcomes): COPD admissions, exercise capacity, body composition, quality of life, and mental health.

Many patients with chronic obstructive pulmonary disease (COPD) also have other diseases referred to as comorbidities. Often these patients require health care by a variety of health care professionals from services linked to hospitals and in the community. Unfortunately, sometimes it may be difficult for these patients to receive appropriate care in a timely manner resulting in a trip to the emergency department. As well, patients may benefit from education that enables them to recognize early signs indicating they are getting sicker and to self-manage their disease. Our study will examine a strategy that includes a case manager who will make weekly phone contact with COPD patients with comorbidity that present either to the emergency department or are admitted to hospital. Weekly contact will focus on teaching patients to recognize worsening symptoms and self-management strategies. The case manager will work with patients, caregivers, community health care providers and hospital specialists to promote communication and optimize care delivery. The investigators will examine the impact of our intervention on the need for emergency department visits and hospital admission. The investigators will also examine the impact on patients' health related quality of life, number of COPD exacerbations, and disease progression.

This study is to evaluate if add-on treatment with inhaled NVA237 (50 µg) once daily (o.d.) via single-dose dry-powder inhaler (SDDPI) further improves lung function and health status and is well tolerated compared to placebo in symptomatic COPD patients with moderate to severe airflow limitation who are already receiving maintenance therapy with inhaled fixed-dose-combination of salmeterol/fluticasone propionate (50/500 µg) twice daily (b.i.d.) via multi-dose dry powder inhaler (MDDPI).

Fluorodeoxyglucose (FDG) positron emission tomography (PET) is now widely used for cancer imaging purpose, notably for preoperative work-up. It aims at visualizing organs metabolism. In case of cancer, metabolism is, classically, increased and some hot spots are visible on PET images. Because of respiratory motion some lung tumours (especially the smallest ones) can be falsely interpreted by the clinician. The investigators developed a respiratory-gated PET method in order to reduce the motion issue. The investigators designed a study to investigate its effect on lung cancer (primary or metastasis) to check if it improves the sensitivity/specificity of PET imaging of the lungs. To that aim, patients presenting a lung nodule on a CT examination can be proposed to participate this study. After the standard PET acquisition (acquired in free-breathing), an additional 10 minutes respiratory-gated PET acquisition is performed without additional injection. After that, a breath-hold (~10s) CT is performed.
