Filter by:This is a study to evaluate the effects of AZD8871 in patients with COPD. Adult male or female patients with moderate to severe COPD, who agree to be in this study, will receive 3 treatments, i.e. 2 different doses of AZD8871 and placebo (dummy medication containing no drug) at once a day for 2 weeks, in a random order. To make the comparison between AZD8871 and placebo as fair as possible, this study is "double blinded." This means that neither patient nor the study doctor will know in which order the 3 treatments will be given. This study will include patients who are between 40 and 80 years of age. In total there will be 42 patients participating in this study at two study centers in the United Kingdom and Germany. The study will have a total of 12 visits for each patient spanning for a period of 4 to 6 months. The study is anticipated to run for approximately 8 months and should not exceed 10 months.
An open-label, single dose Pharmacokinetic (PK) comparability study to demonstrate comparable drug exposure following Subcutaneous benralizumab administration by using accessorized pre-filled syringe (APFS) or autoinjector (AI) devices.
This is a community-based cluster randomized control trial aimed to investigate the impact of lifestyle modification (diet, physical activity, alcohol drinking and smoking) on the development of dementia, diabetes, chronic kidney disease, cancers, chronic obstructive pulmonary disease and cardiovascular disease in an intermediate risk population in mixed urban-rural areas of Ubon Ratchathani.
AZD7594 is a non steroidal, potent and selective modulator of the glucocorticoid receptor (GR) under development for once daily inhaled treatment of chronic obstructive pulmonary disease (COPD) and asthma. Abediterol is a novel and selective β2 adrenergic receptor agonist with the potential for once daily treatment of asthma and COPD in fixed dose combination (FDC) with an ICS or a novel anti inflammatory (AI) agent. This study will be the first clinical study for the combination exposure of AZD7594 with abediterol as 2 compounds in FDC or in free combination via 2 separate dry powder inhalers (DPIs). This study will be conducted in healthy male subjects to minimize the effects of concomitant disease states or medications on study measurements.
Many control mechanisms exist which successfully match the supply of blood with the metabolic demand of various tissues under wide-ranging conditions. One primary regulator of vasomotion and thus perfusion to the muscle tissue is the host of chemical factors originating from the vascular endothelium and the muscle tissue, which collectively sets the level of vascular tone. With advancing age and in many disease states, deleterious adaptations in the production and sensitivity of these vasodilator and vasoconstrictor substances may be observed, leading to a reduction in skeletal muscle blood flow and compromised perfusion to the muscle tissue. Adequate perfusion is particularly important during exercise to meet the increased metabolic demand of the exercising tissue, and thus any condition that reduces tissue perfusion may limit the capacity for physical activity. As it is now well established that regular physical activity is a key component in maintaining cardiovascular health with advancing age, there is a clear need for further studies in populations where vascular dysfunction is compromised, with the goal of identifying the mechanisms responsible for the dysfunction and exploring whether these maladaptations may be remediable. Thus, to better understand the etiology of these vascular adaptations in health and disease, the current proposal is designed to study changes in vascular function with advancing age, and also examine peripheral vascular changes in patients suffering from chronic obstructive pulmonary disease (COPD), Sepsis, Pulmonary Hypertension, and cardiovascular disease. While there are clearly a host of vasoactive substances which collectively act to govern vasoconstriction both at rest and during exercise, four specific pathways that may be implicated have been identified in these populations: Angiotensin-II (ANG-II), Endothelin-1 (ET-1), Nitric Oxide (NO), and oxidative stress.
The STAR-study (STay Active after Rehabilitation) investigates in a randomized controlled trial (RCT) the additional effect of a pedometer-based behavior change intervention (BCI) during in-patient pulmonary rehabilitation (PR) on objectively measured physical activity (PA) 6-weeks and 6-months post PR. The BCI uses the behaviour change techniques a) instruction on how, where and when to perform the behavior, b) prompt goal setting for physical activity, c) prompt self-monitoring of behavior and d) feedback on behavior. The primary outcome of PA will be measured using an accelerometer (Actigraph wGT3X) for a time period of seven days, firstly two weeks before rehabilitation begins (T0 = study phase I) as well as six weeks and six months (T3 and T4) after PR. Additionally to predict PA progression after PR, a complex personal diagnostic, including questionnaires as well as functional assessments, is to be carried out at the start (T1 = start of study phase II) and end of PR (T2). This diagnostic is based on the main ideas of the PA-related health competence model (PARC-model) and especially incorporates physical and psychological personal determinants of PA.
Investigators will aim to conduct an observational study in order to assess very thoroughly all patients implanted by Extracorporeal carbon dioxide removal (ECCO2R) in 10 critical care units of Paris and its surburb (APHP, Assistance Publique des hôpitaux de Paris). Secondary objectives will be: 1. to assess efficacy and safety of ECCO2R, 2. to compare the data issue from the registry to others studies assessing the same population and to other centers and 3. to compare the different ECCOR devices in terms of efficacy and adverse events.
Epidemiological investigations has suggested exposure to air pollution linked with respiratory disease, especially chronic obstructive pulmonary disease. However, the potential mechanisms of adverse effects remains scare. The present study will assess the association between air pollutants and respiratory related parameters to elucidate possible mechanisms.
Chronic obstructive pulmonary disease (COPD) patients often undergo thoracic surgery due to lung cancer and emphysematous changes. One lung ventilation (OLV) used in thoracic surgery aggravates hypoxia and hypercapnia increasing intrapulmonary shunt and dead space.Ketamine provide bronchodilation by inhibiting the reuptake of catecholamines in the circulation. It also serves relaxation of bronchial smooth muscle. Our aim in this study, effects of ketamine on arterial oxygenation, the shunt fraction and the lung mechanics in patients with COPD who administered OLV because of thoracic surgery. Thirty patients with COPD who undergo thoracotomy for lung lobectomy will be included in this study. Patients will be randomly divided to a control group (%0,9 saline- CG) or a keta (ketamine- KG) group. KG will be administered 1 mg/kg ketamine bolus, then 0,5 mg/kg/hour ketamine infusion after the induction, CG will be administered sline bolus, then saline infusion. Peak airway pressure (Ppeak), plato airway pressure (Pplato), static compliance, shunt fraction, PaO2/FiO2 and arteriel blood gas values (Pa02, PaC02) will be recorded before initiation of OLV and 30 minutes intervals after initiation of OLV.To evaluate the postoperative pulmonary complications, Pa02, PaC02 in blood gas and Pa02/Fi02 values will be recorded 20 minute after arrival at postoperative care unit. Patients will be evaluated for pneumonia, atelectasis and acute lung injury at postoperative 72 h and findings will be recorded. 30 day mortality will be recorded.
The investigators will conduct a randomized, controlled, double-blind, crossover trial to determine whether the presence of a portable high-efficiency indoor air filter in the bedroom reduces respiratory symptoms in former smokers compared with placebo. The primary outcomes will be change in St. George's Respiratory Questionnaire - COPD (SGRQ-C) score associated with using a portable high-efficiency indoor air filter during the study period. Secondary outcomes of COPD exacerbations and hospitalizations, daily step counts, medication changes, spirometry, and cardiovascular outcomes will also be assessed.
