Active clinical trials for "Pulmonary Disease, Chronic Obstructive"

Chronicle obstructive pulmonary disease is a worldwide cause of mortality and morbidity. This systemic disease progressively leads to dyspnea, muscle wasting and exercise capacity impairment. Pulmonary rehabilitation is a cornerstone in the management of these systemic effects. Unfortunately, access to pulmonary rehabilitation is limited for many people who would benefit from it, primarily because of a lack of pulmonary rehabilitation and assessment centers. Optimal assessment should include cardiopulmonary exercise testing to determine both the optimal training settings as well as any cardiopulmonary contraindications to pulmonary rehabilitation. However, this is not available in most centers and when it is, consultations are limited. Therefore, pulmonary rehabilitation is often delayed for several weeks and patients can lose motivation. In order to promote pulmonary rehabilitation, the incremental cardiopulmonary exercise testing could be replaced by field tests to individualize pulmonary rehabilitation prescription. The 6-minute stepper test is a new field tool. Its sensitivity and reproducibility have previously been reported in patients with chronicle obstructive pulmonary disease. It is easy to set up in the clinical setting and could be used to individualize pulmonary rehabilitation. The aim of this study was to develop and validate a prediction equation to set rehabilitation intensity for patients with severe to very severe chronicle obstructive pulmonary disease attending pulmonary rehabilitation, with the use of a simple, readily available field test. Therefore the investigators sought to determine, if it exists, a relationship between the plateau heart rate from the first and last 3 minutes of the 6-minute stepper test and the heart rate from the first ventilatory threshold from the cardiopulmonary exercise testing in order to individualize pulmonary rehabilitation in patients with severe to very severe chronicle obstructive pulmonary disease.

Study is conducted to assess the prevalence and structure of comorbidity among patients undergoing abdominal surgery and produce the stratification of the risk of postoperative complications by identifying independent predictors for its development.

The aim of this Post Authorisation Safety Study (PASS) is to assess the incidence of adverse cardiovascular and cerebrovascular events in COPD patients who are new to inhaled fixed triple therapy (dual bronchodilator plus corticosteroid) administered via Dry Powder Inhaler (DPI) compared to new users of pressurized Metered Dose Inhaler (pMDI). Data from clinical practice from different European data sources will be collected. The baseline hypothesis is that the DPI is not associated with different risks of the primary and secondary outcomes, compared with pMDI.

Chronic obstructive pulmonary disease (COPD) is a chronic lung disease affecting an estimated 1 in 10 Canadians. Symptoms include persistent shortness of breath, cough and sputum production. The symptoms can be serious when people with COPD experience a flare of their disease and may lead to hospitalization or death. Improving other conditions that affect COPD control is one way to improve the health of people with COPD. Obstructive sleep apnea (OSA) is the most common breathing problem during sleep, and commonly co-exists with COPD. Although diagnosing and treating OSA is encouraged, it has not been highlighted in guidelines that recommend ideal COPD care. People with COPD and OSA have lower sleep quality and lower oxygen levels during sleep compared to people with OSA. Despite these differences, treatment of OSA in people with COPD is modeled after treatment of OSA in the general population, generally using treatment with continuous positive airway pressure (CPAP) with the possible addition of oxygen through the CPAP machine. There are few studies looking at other types of treatment including noninvasive ventilation (NIV) in people with COPD and OSA. The majority of studies of NIV in COPD has been for people with other reasons to use NIV including acute respiratory failure or chronic hypercarbic respiratory failure and did not include people with risk factors for OSA or who had undergone overnight sleep studies. In Alberta, NIV is provided province wide for people who have both OSA who do not meet certain physiologic targets in their oxygen levels or breathing patterns after CPAP is applied on an overnight sleep study. NIV is provided preferentially to CPAP and oxygen, providing an opportunity to look at health outcomes when NIV is used instead of CPAP for the treatment of patients with COPD. Through this study, we will measure whether people with COPD and a sleep related breathing disorder such as OSA have fewer severe flares of COPD after starting CPAP or NIV. We will evaluate whether the number of Emergency Department visits, hospitalizations or deaths lowers after starting CPAP or NIV.

This study aims to use novel proton-based MRI techniques to assess lung function and structure in healthy volunteers and patients with chronic obstructive pulmonary disease (COPD) and alpha-1-anti-trypsin deficiency (A1ATD). These novel MRI measures will be compared to matched contemporary clinical diagnostic tools, namely pulmonary function tests (PFTs) and computed tomography (CT) scans. MRI has the advantages of avoiding ionising radiation exposure (unlike CT scans) and can also provide regional measures of lung function (unlike PFTs which provide global measures of function). In addition, these MRI techniques do not require the use of any inhaled or injected contrast agents. Some patients enrolled in this study will be undergoing a lung volume reduction (LVR) procedure as part of their normal clinical care. LVR is an intervention for patients with severe lung disease and hyperinflation. It is a palliative therapy that helps to reduce lung hyperinflation through insertion of small valves in the airway or surgical removal of parts of the lung. This can lead to improvements in symptoms such as breathlessness and improve exercise tolerance due to better functioning of the lung. In this study, we will explore how lung MRI measures can be used to assess patients before and after an LVR intervention. This study will take place at the University of Nottingham in collaboration with Nottingham University Hospitals NHS Trust. The study will last for 3 years and participants will be asked to attend a screening visit (lasting up to 1 hour) and either one or two study visits (each lasting up to 3 hours).

New approaches to care transitions must deploy a longer-term and more intensive program that provide an array of services that address underlying social determinants of health (e.g. lack of adequate social support, lack of self-efficacy in managing symptoms and medications, impoverished living conditions, inability to connect with primary care and access. In addition, programs must be adaptable to meet the specific needs of individual patients. Our collaboration of health services researchers, quantitative scientists, and physicians propose to develop and implement a 90-day intensive and comprehensive intervention to support newly discharged patients with COPD and/or CHF. The proposed intervention will utilize a three-person team (registered nurse, clinical social worker, and a pharmacist) to provide an array of medical and social services specifically targeted to meet the needs of individual patients and their families. Aim: To determine using a randomized control trial, whether participation in an intensive series of 7 home-visits that provide tailored medical and social services among newly discharged low-income Medicare patients with COPD and/or CHF results in a) better patient-reported outcomes and b) a reduced likelihood of repeat hospital care (ED use or hospitalization) relative to a group of patients who receive usual discharge instructions.

The objective of this study is to identify key indicators in the follow-up of subjects with different pathologies related to both the person's environment, as well as the perception of their health and general quality of life and related to their disease. To this end, a cross-sectional observational study of qualitative data collection through questionnaires, mostly validated, has been proposed to try to identify these indicators. Based on these questionnaires, the specific objectives of this study are as follows: Unify questionnaires Assess data quality Identify key indicators, through a factor analysis Design a second reduced version of the questionnaires collecting the key indicators and eliminating those items that are exclusive to each other. In order to identify the key indicators, it will be necessary to measure at least 30 subjects from each pathological group, as well as a cohort of at least 100 subjects without pathologies in order to validate and contrast the results. The subjects will be recruited through the own databases of participants in previous trials of the Institute of Biomechanics of Valencia, who have given written consent to be contacted in order to request their participation in any other study where their profile may fit. They will also be recruited and contacted through the collaborating associations (Parkinson Valencia Association, Valencian Diabetes Association, Consorci Hospital General Universitari de València, Arnau de Vilanova Valencia Hospital). The surveys will be included in an online platform specialized in the realization of questionnaires. This data will be exported for further storage, management and analysis. All information will be anonymized for processing and analysis, and may be used under the terms and conditions dictated by the current legal framework. To participate in the study, participants must accept the terms and conditions included in the first page of the survey embedded in the online platform, where the aspects related to the study methodology and the use of them data are exposed. The statistical analysis will treat the data provided by the variables and how they are related to each other, testing differences according to the characteristics of the patient and clinical indicators. For that, non-parametric techniques such as the χ² test, the Kruskal-Wallis test and cluster analysis will be used.

Objectives: 1.- To evaluate the changes in health care and use of services in patients with chronic diseases such as chronic obstructive pulmonary disease (COPD), heart failure and major depression between 2017-2019 and the years 2020-2022, COVID pandemic period, and to see their relationship with clinical outcomes (in terms of mortality, admissions, death, current situation of his disease) and changes in health-related quality of life. 2- To evaluate the health care provided to a cohort of patients diagnosed with SARSCOV-2 (COVID-19 positive) during 2020 based on accessibility, equity and outcomes obtained. 3-To evaluate the evolution of the cohort of patients diagnosed with SARSCOV-2 after two years of follow-up since their diagnosis and create clinical prediction rules for the persistence of symptoms. Methodology. Four cohorts already created in previous projects are included: three of chronic patients, COPD, heart failure, major depression, all of 2017, and for which baseline information is available for follow-up of the health care they received in the 2017-19 period compared to that received during the 2020-22 period and to see the changes in their health-related quality of life from baseline based on generic and specific questionnaires for each of the pathologies included. Another cohort of positive and admitted patients for COVID-19 in 2020 is included, in whom the services received will be evaluated and recorded symptoms persistency that may have had up to two years after their index admission to develop tools for predicting the persistence of symptoms in the medium-long term.

The current literature suggests that the mode of action of benralizumab is to deplete eosinophils through a mechanism of antibody-dependent cell-mediated cytotoxicity. This direct cellular cytotoxicity may not explain all of the benralizumab effects. The investigators propose a set of studies to systematically examine the spectrum of effects of this drug on the immune system.

Chronic Obstructive Pulmonary Disease (COPD) is a chronic disease of the lungs that affects more than 2.5 million Canadians. Patients with COPD experience episodes of lung attacks (or exacerbations). During these attacks, patients experience an intense increase in symptoms, such as breathlessness and cough. It is challenging to decide which patients should be put on treatments that would reduce the risk of such lung attacks. The digitization of health records in many clinics and hospitals means complex risk prediction algorithms can be used to predict the risk of lung attacks to enable personalized care. In this study, our team will implement a risk prediction tool (called ACCEPT) into the electronic health records in two teaching hospitals in Vancouver, British Columbia (BC), Canada. A clinical study will be conducted to evaluate if the use of this tool results in patients with COPD receiving better care with better outcomes, and if they are more satisfied with the care they are receiving.
