Filter by:Pneumonia is a major infectious cause of death worldwide and imposes a considerable burden on healthcare resources. Obstructive lung diseases (COPD and Asthma) are increasingly important causes of morbidity and mortality worldwide. The patients with community-acquired pneumonia (CAP), and acute exacerbations of obstructive lung diseases commonly present with similar signs and symptoms. For antibiotic use, the rapid and accurate differentiation of clinically relevant of bacterial lower respiratory tract infections from other mimics is essential. Sphingosine-1-phosphate (S1P) is a bioactive sphingolipid has both extracellular and intracellular effects in mammalian cells. S1P is involved in many physiological processes including immune responses and endothelial barrier integrity. In term of endothelial barrier integrity, S1P plays a crucial role in protecting lungs from the pulmonary leak and lung injury. Because of the involvement in lung injury, S1P would be the potential biomarker of pneumonia. Based on the above evidence, S1P plays an essential role in the pathobiology of pneumonia was hypothesized.
The purpose of this study is to establish the reference values of impulse oscillometry (IOS) in healthy Chinese, and compare the indices of IOS in patients with lung disease, such as chronic obstructive pulmonary disease (COPD), asthma, interstitial lung disease (ILD), and upper airway Obstruction (UAO).
For patients admitted to the medical ward, it is usually difficult to predict if their clinical condition will deteriorate, however subtle changes in vital signs are usually present 8 to 24 hours before a life-threatening event such as respiratory failure leading to ICU admission, or unanticipated cardiac arrest. Such adverse trends in clinical observations can be missed, misinterpreted or not appreciated as urgent. New continuous and wearable 24/7 clinical vital parameter monitoring systems offer a unique possibility to identify clinical deterioration before patients progress beyond the point-of-no-return, where adverse events are inevitable. The WARD-COPD project aims to determine the number and duration of cardiopulmonary micro events during the first 4 days after hospital admission with Acute Exacerbation of COPD. We will also test the server installation, develop a database of core data and assess the frequency of artefacts and failure to capture the continuous monitoring signal.
Although non-invasive ventilation (NIV) usage has increased significantly over time in COPD exacerbation, a great percentage of patients (~30%) present contraindications to NIV or cannot tolerate it. Nasal high flow (NHF) has been introduced for the management of hypoxemic respiratory failure in adults with favorable effects on ventilation and respiratory mechanics. The above mentioned NHF positive effects has been observed also in stable COPD patients with or without chronic hypercapnia. In this study, the investigators hypothesize that NHF is not inferior to NIV for respiratory support in patients with COPD exacerbation and acute or acute on chronic hypercapnic respiratory failure.
The study is a 44 weeks, prospective, randomized, placebo-controlled, double-blinded, parallel group two-center trial. Forty patients are recruited among the outpatients of the chronic obstructive pulmonary disease (COPD) clinic, Hospital of South West Jutland and Lillebælt Hospital according to the inclusion and exclusion criteria. The patients are randomized to receive liraglutide 3 mg per day (initial dose 0.6 mg, increasing by 0.6 mg weekly until 3 mg is reached) or placebo. At baseline, after four weeks (assessment of the acute effect of liraglutide), 20 weeks, and 40 weeks (assessment of the combined effect of liraglutide and weight loss) and at week 44 (assessment of the weight-loss after discontinuation of liraglutide) the patients are assessed by physical examination, carbon monoxide (CO) diffusion test, pulmonary function test, biomarkers of inflammation (CRP, interleucine-6 (IL-6), monocyte chemitactic protein-1 (MCP-1)), Fluorodeoxyglucose (FDG)/PET-CT scan of the lungs, 6-minute walking test, respiratory polygraphy and validated questionnaires including basic dyspnea index, transition dyspnea index, COPD Assessment Test (CAT)-score, short-form-36 (SF-36) and Epworth Sleepiness Score.
This study will evaluate the diagnostic measures (including blood eosinophil counts) commonly used by lung specialist's in routine clinical care of subjects with COPD in Germany and how these diagnostic tests influence the physician's treatment decisions. The study will be conducted in three parts. In the first part, lung specialist's, who will not participate in the survey, will develop doctor's questionnaire. The second part is an interventional cross-sectional study, wherein approximately 30 lung specialists will be enrolled and data on their perspective on diagnosis and treatment of COPD subjects will be collected via the revised doctor's questionnaire. The third part is a retrospective non-interventional study where each doctor will collect retrospective data from selected subjects with COPD from the time of informed consent up to 12 months before. The retrospective data will be collected from subject files of approximately 250 subjects with COPD.
The aim of this study is to assess the effectiveness of a home-based exercise training program in COPD patients who have completed a pulmonary rehabilitation.
Chronic Obstructive Pulmonary Disease [COPD] is a major cause of chronic morbidity and mortality worldwide. COPD is characterized by persistent progressive airflow limitation that adversely affects the ventilation/perfusion (V/Q) matching and mechanics of the respiratory muscles and leads to hypoventilation and reduced gas transfer. COPD was identified as a significant comorbidity associated with increased incidences of postoperative pulmonary complications and prolonged hospital stay. MgSO4 either intravenous or inhalational has been shown to promote bronchodilation and to improve lung function in asthmatic patients. MgSO4 either intravenous or inhalational has been shown to promote bronchodilation and to improve lung function in asthmatic patients. Administration of MgSO4 in patients with stable COPD was associated with reduced lung hyperinflation and improvement of respiratory muscle strength. This randomized control trial is designed to assess the effect of intravenous MgSO4 infusion on oxygenation and pulmonary mechanics and incidence of postoperative pulmonary complications and length of hospital stay in patients with COPD undergoing cancer larynx surgery.
High flow nasal cannula (HFNC) has been shown to improve oxygenation and facilitate weaning in hypoxemia patients. Some clinical studies show the benefits of using HFNC in COPD patients, including reducing dead space and work of breathing. However, no clinical study has been to investigate the value of HFNC in weaning COPD patients from invasive ventilation. Thus, we proposed a randomized controlled trial to compare the use of HFNC and noninvasive ventilation (NIV) in weaning COPD.
In this pilot project, 35 lung transplant candidates will be recruited to participate in a three month individualized home-based program focused on exercise and nutrition optimization. This pilot is designed to assess the feasibility of treating frailty before lung transplantation. Participants will complete a 1 day in-person assessment and training session that will include baseline frailty assessment, determination of exercise capacity, and a determination of nutritional status. Based on American Thoracic Society Guidelines and a diet evaluation by a registered dietician, information gathered during the assessment will be used to develop a tailored prescription for exercise and nutrition to be continued at home. Participants will also be taught self-management skills specific to control of dyspnea, fatigue, motivation, and support. Participants will receive training in protocol implementation at home by a coordinator trained in principles of behavior change, adult learning theory, and dyspnea control techniques. Subjects will be provided tablet computers with an app called Aidcube preloaded and taught how to interface with the app. Aidcube is a commercially available exercise platform designed for patients with lung and heart diseases. It was designed with the input of physicians, physical therapists, respiratory therapists, nutritionists who specialize in patients with lung and heart disease and adheres to professional society guidelines for exercise and rehabilitation in patients with lung disease. Subjects will then adhere to a individually tailored home exercise and nutrition program based on their exercise capacity. Aidcube allows clinicians (or in this case the PI and co-PI) the ability to design a customized program of exercises and diet plan through the "provider interface". The subjects interacts with the "patient interface" to complete their exercise program during the 8 week study intervention. This goal of this pilot project is to determine the feasibility of implementing a home-based exercise and nutrition program with patients with advanced lung disease awaiting lung transplantation. Information on Aidcube can be found at https://www.aidcube.com. The overarching aim of this pilot study is preparatory investigation to evaluate the feasibility of performing a home-based intervention to treat frailty in lung transplant candidates. Specific aims: - Establish a sampling time frame and recruitment techniques. - Assess willingness to participate - Assess adherence and compliance. - Identify logistical problems in the in-person and at-home components of the intervention - Determine the resources needed for a full-scale study. - Provide funding bodies evidence that research team is competent and knowledgeable. - Provide funding bodies that the study is feasible
