Filter by:The NOVEL Observational longiTudinal studY (NOVELTY) is an observational study of obstructive lung disease and is a multi-country, multi-centre, prospective, longitudinal cohort study which will recruit patients with a diagnosis, or suspected diagnosis, of asthma and/or Chronic Obstructive Pulmonary Disease (COPD). Patients will undergo clinical assessments and receive standard medical care as determined by their treating physician. Patients enrolled in NOVELTY will be followed up yearly by their treating physician for a total duration of three years. In addition, patients will be followed up remotely every 3 months. The NOVELTY study will collect data currently lacking to allow for multinational data collection to fill regional/local gaps and improve comparability across regions.
Influence of tuberculosis (TB) on natural course of chronic obstructive lung disease (COPD) has not been well known. This study was designed to investigate the effects of history of TB on the long-term course of COPD.
The Pulmonary Fibrosis Foundation Patient Registry will collect data on at least 2,000 patients with interstitial lung disease (ILD) at approximately 40 clinical sites in the US. The Registry is targeting enrollment of approximately 60% of the 2,000 ILD participants to have idiopathic pulmonary fibrosis (IPF). The aim of the Registry is to create a cohort of well-characterized patients with interstitial lung disease (ILD) for participation in retrospective and prospective research
ScreenFlow is a chronic obstructive pulmonary disease (COPD) screening tool currently being studied and iteratively developed that incorporates a questionnaire administered on a tablet and data from a digital peak flow meter to calculate a risk score to identify the risk of developing moderate-to-severe COPD for the participant. The purpose of this study is to assess the usability of ScreenFlow deployed as a free-standing kiosk and observe where users encounter trouble navigating the system. The kiosk will be situated in a public area of a hospital where passersby can approach and fill out a ScreenFlow survey if they meet the eligibility criteria. A subset of participants will be asked to participate in a follow-up questionnaire about their experience using the system and about any follow-up action they may have taken caused by their results from the ScreenFlow screening.
The purpose of this study is to estimate a direct/indirect medical cost and to provide evidence establishing efficient strategies to reduce medical costs of COPD in Korea.
Oxygen supplementation has been proven to be effective in hypoxemic COPD patients by increasing oxygenation and reducing dyspnea. In clinical practice there are three common oxygen delivery systems used: continuous oxygen flow (CF), demand oxygen delivery with liquid oxygen (DDL) and demand oxgen delivery with portable oxygen concentrator (DDC). The CF involves considerable wastage of oxygen because oxygen is supplied during in- and exhalation. Demand oxygen delivery saves oxygen and results in a comparable oxygen saturation at rest in COPD patients. However, it is unknown, if oxygen supplementation via demand oxygen delivery is also sufficient during exercise in hypoxemic COPD patients. In addition, it has to be considered that the lower weight of demand oxygen delivery system might enable patients for higher physical activity level and mobility in daily life. The effects of These three oxygen delivery systems shall be investigated by a randomized, controlled cross-over Trial. Every patient has to perform an Incremental Shuttle Walk Test and three Endurance Shuttle Walk Tests with three different oxygen supplementation (via CF, DDL or DDK) in randomized order.
This study will examine the inflammatory response to exercise encompassed as part of a standard pulmonary rehabilitation programme in patients with chronic obstructive pulmonary disease (COPD). Patients will be split into two groups, frequent exacerbators or infrequent exacerbators, dependent upon exacerbation history to compare responses to pulmonary rehabilitation amongst phenotypes.
Scleroderma is an autoimmune disease with skin manifestations and may have pulmonary involvement. Obstructive sleep apnea (OSA) may also be seen in scleroderma. Less is known regarding the prevalence of OSA in scleroderma and its association with pulmonary involvement.
This prospective, multicenter, cohort study is designed to validate Anxiety Inventory Respiratory Disease questionnaire in patients with Chronic Obstructive Pulmonary Disease (COPD). The primary purpose of this study is to assess the validity of the Anxiety Inventory Respiratory (AIR) scale in detecting anxiety in relation to the DSM-V criteria in patients with COPD. - To evaluate associations between COPD symptom scores assessed by the CAT questionnaire and MMRC dyspnea scale and measures of depression and anxiety - To evaluate associations between physiologic measures of lung function (spirometry) and exercise tolerance (6 minute walk) and measures of depression and anxiety - To evaluate associations between exacerbations of COPD and the prevalence of anxiety and depression in a cohort of COPD patients
Chronic Obstructive Pulmonary Disease (COPD) patients in Long-Term Home Oxygen Therapy (LTOT) have a reduction in airflow that is not totally reversible. This obstruction may be associated with an abnormal inflammatory response of the lungs as a result of inhalation of toxic particles, particularly to cigarette smoke. Furthermore, COPD patients also present limited symptoms to physical exercise, significant extrapulmonary effects, including weight loss, nutritional abnormalities and skeletal muscle dysfunction. Hyperinflation has been identified as a major cause of dyspnea and is currently believed to be already present in the early stages of the disease, causing limitations in physical capacity. The progressive exertional dyspnea is most associated with impairment to activities of daily living, decreased quality of life and worse prognosis. Traditionally, the severity of COPD is defined by the degree of obstruction, as measured by forced expiratory volume in one second (FEV1) after bronchodilator use (post-BD) and can be classified as mild, moderate, moderately severe and very severe disease. In the group of patients with Advanced Pulmonary Disease (APD), those with partial pressure values of oxygen (PaO2) lower or equal to 55mmHg, or arterial oxygen saturation (SaO2) lower or equal to 88% in ambient air; or those with PaO2 values between 55-60 or SaO2 lower than 90%, with evidence of pulmonary hypertension or polycythemia require LTOT, over 15 hours / day, with evidence of increased survival. The aim of this study is to evaluate the erythrocyte membranes stability in COPD and APD patients in LTOT compared to healthy subjects. It is a cross-sectional, observational study with evaluation of erythrocyte membranes stability among the groups as well as lung function, physical testing, laboratory analysis, oxidative stress and quality of life questionnaires. As red blood cells are the cells responsible for the gas exchange in the lungs and peripheral tissues, and since the patients with COPD and APD have gas exchange impairment compared to the healthy group, it is expected to find a difference in erythrocyte membranes stability and levels of oxidative stress among the groups.
