Filter by:This is a pilot study on the impact of switching from cigarettes to Electronic Cigarettes (EC) on disease-related clinical symptoms and biomarkers of harm in smokers with preexisting Chronic Obstructive Pulmonary Disease (COPD). The researchers hypothesize that the smokers who switch to EC completely or significantly will experience reduced COPD symptoms, risks of exacerbations, and decreased levels of oxidative stress and inflammation.
Major progress has been made in the area of cardiovascular disease, but we believe that further progress will involve mechanistically addressing underlying respiratory causes including chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea (OSA). The most common cause of death in COPD is cardiovascular, although mechanisms are unknown. OSA has been associated with major neurocognitive and cardiovascular sequelae, the latter likely a function of autonomic nervous system abnormalities, oxidative stress, inflammation, and other pathways. Recent data suggest that individuals with OVS die preferentially of cardiovascular disease compared to OSA or COPD alone, although mechanisms are again unclear. The combination of OSA and COPD may lead to profound hypoxemia. Individuals with COPD can develop pulmonary hypertension via disturbances in gas exchange and parenchymal injury leading to loss of pulmonary vasculature. OSA has been associated with mild to moderate pulmonary hypertension, but the situation may be worse if combined with parenchymal lung disease. The biological response to sustained hypoxemia has been carefully studied as has the topic of intermittent hypoxemia; however, to our knowledge, very little research has occurred regarding the combination of sustained plus intermittent hypoxia as seen in OVS. For example, we do not really know whether individuals with OVS develop coronary disease, right or left heart failure, dysrhythmias or some combination of abnormalities predisposing them to cardiovascular death. Thus, design of interventional studies is challenging as causal pathways are poorly understood despite our considerable preliminary data addressing these issues. The purpose of this study is to examine vascular mechanisms in individuals with COPD/OSA overlap syndrome (OVS) compared with matched individuals with obstructive sleep apnea (OSA) alone or chronic obstructive pulmonary disease (COPD) alone and to perform a phase II pilot mechanistic clinical trial in OVS to examine the effect size of nocturnal bi-level positive airway pressure (PAP) vs. nocturnal oxygen therapy in cardiovascular outcomes.
The health care is faced by a growing challenge in the years to come: increasing age and chronic morbidity raising the costs, combined with decreased work participation. Among the conditions on the rise, we find anxiety/depression, musculoskeletal conditions, type 2 diabetes and chronic obstructive pulmonary disease. Recently, the rise of the Corona pandemic has yielded another group of (primarily young) patients with decreased work capacity, the post-Covid syndrome sufferers. The aim of the present study is to establish, describe and summarize the experiences with a novel approach to rehabilitation for five of the most costly conditions; 1) low back pain, 2) chronic obstructive pulmonary disease, 3) type 2 diabetes mellitus, 4) mixed anxiety/depression and 5) post-Covid fatigue. The concentrated interdisciplinary rehabilitation is characterised by three phases; 1. Pre-intervention preparation (1-2 months): with the aim to mobilize the patients' resources for change 2. Concentrated group intervention (2-5 days): interdisciplinary team - individually tailored training (further described below) 3. Post-intervention follow-up (1 year): digital follow-up with the aim of integrate the changes into everyday living The concentrated intervention: The core intervention is based on trans-diagnostic features of the highly successful 4-day intervention for Obsessive Compulsive Disorder, namely: - Initiate treatment when the patient is ready for change - Focus on the behavioral patterns which maintain the disorder and help the patient to identify situations where they can choose to break the pattern ("micro-choices"). - Assist the patient when they practice breaking the patterns. This may pertain to how they do physical training or to the way they walk, sit, eat, talk, take their medication and sleep, or to how they engage in social activities or take care of others. - Use long sessions to ensure that they face a broad range of potential micro-choices - Work side-by side with others going through an analogous pattern of change - Prepare them for taking responsibility for integrating the change into every-day living Main outcomes will be 1. Completion rates 2. Patient satisfaction 3. Changes to perception of illness 4. Patient activation Secondary outcomes will be 1. Level of functioning 2. Qualitative description of participants' experiences
To evaluate the regenerative capacities of mesenchymal cells composing the microenvironment of alveolar type 2 cells in a population of patients, undergoing thoracic surgery for suspected cancer, who are smokers with and without COPD compared to non-smokers patients
The study aims to assess the differences between spirometry performed with the NuvoAir Air Next spirometer in the clinic setting with both direct and virtual supervision via a video call, and in the home setting with virtual supervision. This is will be achieved by comparing lung function values, specifically the FEV1 and FVC measurements. We also wish to evaluate participant's perceptions of home spirometry, by using a survey. This is a multi-centre, cross-over study. The study will enrol participants with a diagnosis of asthma and COPD, across participating study sites until 68 have completed the study.
COPD (Chronic Obstructive Pulmonary Disease) is a disease of the respiratory system characterised by irreversible airway obstruction of varying severity. The disease (known as COPD, Chronic Obstructive Pulmonary Disease) is progressive and is associated with a state of chronic inflammation of the lung tissue, which leads to a real remodelling of the bronchi causing a significant reduction in airway flow. Among the possible treatments, while the placebo is considered as an inert treatment, lacking any intrinsic therapeutic properties, there is evidence in the literature that not all placebos are equivalent and some are more effective than others, as for example in the case of migraine or osteoarthritis. The differences found between different types of placebos (e.g. oral, subcutaneous, intra-articular...) indicate that placebos are not inert but rather consist of multiple psychosocial elements that are part of the ritual of the therapeutic act. This is also the context for the studies by Lacasse et al. (for the International Nocturnal Oxygen (INOX) Research Group et al., 2017) and Jarosh et al., who investigated the effects of oxygen therapy both during sleep and during the course of daily life, studying its influences through the use of placebo in patients suffering from hypoxemia. However, in the literature, there are no studies investigating the role of oxygen (O2) during the performance of a test such as the Walking Test, otherwise known as the 6 Minute Walking Test (6MWT) compared with a placebo in patients with Chronic Obstructive Pulmonary Disease (COPD), nor whether the use of the latter would lead to comparable results.
Particulate matter (PM) associated cardiorespiratory and vascular dysfunction (CaRVD) poses a significant global health burden. The World Trade Center (WTC) destruction on September 11, 2001 led to an intense deposition of particulate matter (WTC-PM) into aerodigestive system. WTC associated morbidities include respiratory, gastrointestinal, chronic rhinosinusitis, cancer, mental health concerns and more recently a focus has been on cardiovascular disease. This proposal will investigate the development of WTC-cardiorespiratory and vascular dysfunction (WTC-CaRVD) which is firmly within the purview of the James Zadroga 9/11 Health and Compensation Act. WTC-PM exposure causes heterogeneous obstructive airways disease (OAD) patterns, which include airway hyperreactivity (AHR) and loss of FEV1. Early diagnosis and therapeutic options are few, in part due to limited understanding of their pathogenesis. While pulmonary vascular changes are classically thought to occur due to the hypoxemia of late OAD, recent investigations show that vascular dysfunction occurs early in OAD. This vascular hypothesis of OAD postulates that pulmonary vasculature remodeling leads to loss of lung function. Early evidence of WTC-CaRVD includes increased prevalence of cardiovascular disease risk factors such as metabolic syndrome, elevated pulmonary artery/aorta ratio, and cardiovascular biomarkers (such as CRP). Murine models of WTC-PM exposure show inflammation, AHR both acutely and persistently and reflect what is seen in FDNY 1st responders. Airway and cardiac remodeling were also persistent features of WTC-PM exposure in the study team's murine models. Therefore, the study team will focus on Heme Oxygenase-1 (HO-1), a mediator of oxidative stress, known to stimulate collagen formation and is also induced after WTC-PM exposure. Furthermore, pathways and mechanisms of WTC-CaRVD warrant further study and are the focus of the 5-year proposal. The HYPOTHESIS is that WTC-PM exposure causes WTC-CaRVD mediated by HO-1. First responders with AHR will have features of WTC-CaRVD, and will demonstrate a unique biomarker profile compared to controls.
This is a two-armed, parallel-design, pre-/post-intervention assessment study. The investigators will conduct a randomized controlled trial for ED GOAL on a cohort of 120 older adults with serious illness to collect patient-centered outcomes and determine preliminary efficacy on increasing advance care planning engagement (self-reported and/or in the electronic medical record) one month after leaving the emergency department. The investigators will also conduct qualitative interviews with participants of ED GOAL.
The objective of the study is to evaluate the efficacy of home High Flow Oxygen for the reduction of severe exacerbation following admission for a severe exacerbation of COPD or death against standard oxygen therapy.
COPD patients often experience multiple symptoms (e.g. dyspnea, cough, and deteriorating quality of life) and have imposed a substantial economic and social burden on health care. The current proposal is to evaluate the feasibility and acceptability of a pilot trial of a smartphone-based instant messaging self-management support program to improve the quality of life in patients with COPD.
