Filter by:A preliminary study to evaluate a new nasal interface and portable ventilator system in comparison to standard oxygen therapy in patients with severe chronic lung disease.
The objective of this study is to evaluate the safety and effectiveness of the RePneu Lung Volume Reduction Coil (LVRC) in patients with Alpha-1-Antitrypsin deficiency (AATD) caused emphysema. The hypothesis is that emphysema in AATD patients shows similar tissue destruction profile was well as symptoms and thus will respond favorably to LVRC treatment, demonstrating improvement in lung function, exercise capacity, and quality of life relative to their baseline status.
The purpose of the study is to determine the efficacy of mindfulness-based cognitive therapy (MBCT) as an add-on to pulmonary rehabilitation (treatment as usual, TAU) in chronic obstructive pulmonary disease (COPD). The investigators hypothesize that compared to treatment-as-usual, the add-on of MBCT will result in improved psychological (anxiety, depression) and physical outcomes (physical health status, activity level, inflammatory markers). Furthermore, the investigators will explore the possible moderating role of individual differences in sociodemographic and disease-related characteristics and the perceived quality of the therapeutic alliance, as well as the mediating role of mindfulness, breathlessness catastrophizing, self-efficacy, and self-compassion for the hypothesised effect.
Title: Pro-to-COLD, Procalcitonin to Chronic Obstructive Lung Disease, COLD: Chronic Obstructive Lung Disease, Regarding: Patients hospitalized with suspected acute exacerbation of COPD + / - pneumonia. Background: Patients with COPD exacerbation often get antibiotics. There is considerable criticism of this, many of these patients are not bacterially infected and the antibiotics overconsumption can lead to resistance development and side effects. The purpose: To show that one can reduce the consumption of antibiotics among patients hospitalized for worsening of COPD disease in a population of Danish COPD patients by giving antibiotics depending on the value of the biomarker procalcitonin measured in the blood. A sub-objective is a validation study of mini VIDAS ® / Biomérieux equipment to the current gold standard in measuring procalcitonin, Kryptor/ BRAHMS. Subjects: All patients with confirmed/suspected COPD admitted with COPD exacerbation to the Acute Admissions Unit/ Pulmonary dept. in weekdays. Participants must be adults and be of age and there must be a signed informed consent. Method: 1) Controlled (Quasi-randomized): Even and uneven (concealed) digit of patient´s danish personal identification number, not last digit (gender-fixed) (CPR-number). Even = procalcitonin-guided, Uneven = Control. 2) Collect and analyze procalcitonin (PCT)-samples of patients in the PCT group at admission and then every 2 day. Samples analyzed throughout the week: Vital Status looked up 28 days after inclusion. Create a biobank in the study consisting of blood à 8 ml up to a maximum of 4 times taken for PCT measurements, the subsequent validation study of MiniVIDAS ®. Biobank destroyed 15 years after the completed project. Statistical considerations: 1. Sample size / Sample Size: A total of 120 patients (please see the basis for this estimate of the Protocol). 2. Analyze: A) Antibiotics stopped on day 5 B) Defined Daily Doses Reads aloud, 1) narrow spectrum, 2) broad spectrum, and 3) a total of the two groups between the (Mann-Whitney U test) C) Hospitalization within 28 days after the first hospitalization the year - the two groups between (Mann-Whitney U test). Doctor Jens-Ulrik Jensen stands for analyzes. Statistics program "SAS v. 9.1.3" is used. Economics: The study funded by the participating departments. Responsibility: The study was conceived and run by doctors in Pulmonary Medicine Department and Department of Clinical Pharmacology, both Bispebjerg Hospital and Department of Clinical Microbiology, Hvidovre Hospital. Science Ethics: There has been a thorough research ethics discussion of the project in the project with emphasis on an assessment of the advantages and disadvantages that might be for the participating patients and society as a whole now and in the future. Conclusions A and B of this discussion is summarized as: A. Advantages and Disadvantages: The treating physician has at any time the opportunity to start / continue antibiotic behandlling for the overall assessment whether PCT value. In addition, in the past, in large studies with a total of> 2000 patients, demonstrated that there are drawbacks to the use of antibiotics depending on a displayed value of PCT in patients hospitalized with acute exacerbations of COPD. Mortality and hospitalization will be monitored in this study. However, there may occur side effects to blood sampling, usually transient ecchymosis blood sampling site. If the strategy results in a reduced consumption of antibiotics, it is expected that the incidence of antibiotic-associated adverse events decreased - this for the benefit of the patient. B. Usefulness for society: Based on the results from this study will be a high degree of certainty to conclude whether this new treatment strategy can provide benefits for future patients in the form of reduced antibiotic consumption, less antibiotic associated adverse events, reduced resistance development / selection among bacteria and overall lower economic costs. Based on these considerations, believes the project, the project can be carried out with respect for the participating subjects to integrity. Quantity: It is expected to be included 120 patients in this scientific study. Database: data (case report forms) stored in archive of Pulmonary Medicine Department for 15 years. Create a database with the information. Personally identifiable data will only be present in the clinical hospital. During the completion of the experiment can provide essential health information about the subject's state of health. This will the subject be informed, unless clearly opted out of this on the consent form. The project reported to the Data Protection Agency. Level: With blood sample (8 mL) on day 1 and then every 2 days in the intervention group (the "active group"), this part of routine blood sampling. At discharge stops blood and the patient should not attend the blood after discharge.
The purpose of the research (or "knowledge gap" this research is designed to fill) is to understand the science of how the combination therapy of 2 drugs (inhaled longacting beta-agonists(LABA) and inhaled corticosteroids (ICS), which are commonly used in chronic obstructive pulmonary disease (COPD) patients, is better than each drug alone. ICS and LABA both have antiinflammatory properties; that is, they dampen the inflammation in the cells of the airways in the lungs. The combination of LABA and ICS has also been shown to improve clinical effectiveness in asthma patients. The addition of a LABA to LOW doses of ICS has been shown to be more clinically beneficial in asthma than the use of HIGH doses of ICS alone. This has allowed a reduction in the total ICS dose and minimised the adverse side effects of inhaled corticosteroids. Recent evidence suggests that the use of combination therapy of LABA and ICS may also improve clinical effectiveness in COPD patients. Investigators will address this hypothesis by examining the inflammation cells of COPD direct from the site of disease (the airways) by looking at sputum/mucus. This research will build on the existing knowledge of the science of how these drugs work in asthma and COPD and allows us to understand the molecular science, which may support new future drug targets for patients with COPD, which are greatly needed.
The purpose of this study is to investigate how budesonide/formoterol fumarate dihydrate (Symbicort ©) affects dynamic hyperinflation in patients with obstructive disease using Optoelectronic Plethysmography (OEP). This study is unique as it will be the first randomized, doubleblind, crossover study with a placebo inhaler and budesonide/formoterol fumarate dihydrate as the intervention which will evaluate the effects on ventilatory mechanics through the use of OEP. The investigators plan to demonstrate that budesonide/formoterol fumarate dihydrate impacts dynamic hyperinflation which can be detected with OEP, and that budesonide/formoterol fumarate dihydrate may have an effect in the short term on exercise capacity during a constant load exercise test. The changes in ventilatory mechanics measured after budesonide/formoterol fumarate dihydrate by OEP will provide a unique evaluation of budesonide/formoterol fumarate dihydrate in a controlled setting also demonstrating the utility of OEP in evaluating of the effects of a medical treatment on hyperinflation in individuals with chronic obstructive lung disease (COPD). 1. Primary Objective/Hypothesis: Our objective is to measure baseline, post treatment and post exercise spirometry and evaluate exercise dynamic hyperinflation before and after treatment using OEP. The investigators hypothesize that budesonide/formoterol fumarate dihydrate will decrease dynamic hyperinflation as measured by OEP. 2. Primary Endpoint: Our primary endpoint is the change in dynamic hyperinflation, specifically end expiratory volumes, dynamic lung volumes and diaphragmatic paradoxical breathing as measured by OEP. 3. Secondary Objective: Our secondary objective is to evaluate duration of steady state exercise and exercise capacity before and after treatment. Our secondary hypothesis is that decreases in dynamic hyperinflation during exercise will lead to improvements in dyspnea with exercise, and allow for increases in exercise capacity. 4. Secondary endpoint: Exercise time, change in Borg scale at rest vs. Borg scale at steady state vs. Borg at end exercise.
This study seeks to study the effectiveness of a short mindfulness based pulmonary rehabilitation program prior to a surgical resection in patients with lung cancer and severe Chronic Obstructive Lung Disease (COPD).
Background: Portable oxygen concentrators (POCs) featuring the latest integrated oxygen conserving devices (OCDs) provide greater patient accessibility and mobility during ambulation and travel. Recent POCs are compact, lightweight, battery-operated, and require no refill-time, thus meeting patients' clinical and lifestyle needs. There is, however, a lack of research on the clinical performance of the latest POCs that could help to determine their ability to maintain patients' oxygen saturations ≥ 90 % during exercise. Aim: The purpose of this study is to compare the ability of three POCs, with maximum oxygen production capabilities of 950 to 3000 ml per minute, to maintain oxygen saturations ≥ 90 % in patients with chronic lung disease during exercise. Method: Six minute walk tests (6-MWTs) will be administered in order to measure oxygen saturations by pulse oximetry (SpO2) in up to 20 patients with a diagnosis of either Chronic Obstructive Pulmonary Disease (COPD), or Pulmonary Fibrosis (PF) with documented exertional oxygen desaturations of ≤ 85% on room air. All participants will participate in 4 different 6-minute walk tests: the first will be a control walk performed with the participants' current oxygen system set at their prescribed exertional flow rate. Then, the participants will perform a walk test with each of the three POCs set at the units' maximum pulse dose setting. The order in which the participants use the POCs will be randomly assigned using a sequence generator. Hypothesis: It is hypothesized that all three POCs will provide oxygen saturations ≥ 90 % during exercise in patients with chronic lung disease with moderate to severe exertional oxygen desaturation.
The investigators assume that by analysis of different volatile organic compounds in the breath, using nanotechnology, the investigators will be able to identify a unique respiratory signature of different diseases including asthma, chronic obstructive pulmonary disease (COPD) and pulmonary hypertension.
The purpose of this study is to investigate whether patients with a preoperative reduced pulmonary function have a better preserved oxygenation capacity after open heart surgery, using either pulmonary perfusion or pulmoplegia compared with TAVI and the control-group with standard ECC (Extra Corporal Circulation).
