Shortness of breath (dyspnea) during exercise is a major source of distress and is a commonly reported symptom in patients with cystic fibrosis (CF). A recent treatment option known as Orkambi, which combines the drugs lumacaftor and ivacaftor, may be used in patients with CF to help improve lung health. However, the effects of this combination therapy on dyspnea and exercise performance, a known predictor of survival in CF, are not clear. The investigators aim to understand the effects of Orkambi on these symptoms and to gain new insight into the potential health improvements in CF from using this treatment option.
Critically ill patients often succumb to acute respiratory disease (rapidly developing disease affecting the lungs). The lungs are the commonest organ to fail and require support in the intensive care environment. However, no accurate methods exist that can be used at the bedside to tell what is causing deterioration in a person's lungs. There are various examples of acute respiratory diseases that can occur as a result of numerous different causes, have a high risk of death and cannot be treated easily with drugs. When trying to accurately diagnose and classify these lung diseases there is a risk that the type of respiratory disease is misdiagnosed, missed or the level of severity is not captured. By using the field of optical molecular imaging and employing novel techniques and technologies, the investigators hope to demonstrate here that a bespoke chemical probe administered in micro doses (tiny doses) directly into the distal lung can rapidly and accurately detect activated neutrophils (cells of the immune system that are implicated in the development of these severe conditions), and so work towards a bedside test which could be used to diagnose, monitor and classify the disease in patients who are critically ill in the future. The population for this study are in intensive care where patients are normally intubated (have a breathing tube) due to the severity of their illness, this may be because of respiratory problems or respiratory problems can rapidly develop. Participants will have the chemical probe administered into their lungs and pictures taken through the tube already in place. As this probe lights up when it comes into contact with neutrophils the investigators will be able to tell if neutrophils are present. This will inform a larger study in which it's hoped that the method can be used to inform clinical decisions. The first procedure will take place within two days of initiation of mechanical ventilation and the direct contact with the study team will be completed within nine days.
Death in Ataxia telangiectasia (A-T) is usually due to cancer or chronic lung failure around 20 years of age. Despite low lymphocyte counts (CD3, CD4, CD8 and CD19), IgA and IgG subclass deficiency opportunistic and acute severe respiratory infections are rare. The prevailing wisdom is that an immunoglobulin replacement therapy is not necessary in most of the patients. However no placebo controlled trials have been performed so far. The aim of this trial was to investigate the prevalence of mild and severe respiratory infections and / or chronic cough in classical A-T patients compared to healthy controls.
This is a safety study to compare the safety of receiving a lung treated with the Toronto EVLP System™ by SPONSOR in SPONSOR's dedicated facility against standard lung transplantation.
The purpose of this study is to determine whether the hospitalized patients with increased waist circumference exhibit cardiorespiratory alterations after chest physical therapy.
The investigators aim to use hyperpolarized xenon gas magnetic resonance imaging (MRI) and computed tomography to develop a new technique capable of objectively and quantitatively describing regional and structural lung abnormality. Since this is a relatively novel technique, the investigators first need to acquire imaging and clinical data from a group of participants with normal lungs. The investigators hope to generate an "atlas" of normality, which will form the foundation of future studies to compare with patients suffering from chronic respiratory disease. The investigators also aim to validate the new technique in terms of intra-subject reproducibility.
Despite the implementation of modern public health interventions, 1 in 5 adults in the United States are either current or former smokers and remain at risk for the development of chronic lung diseases. It is unknown how or why any one individual smoker can develop a wide range of lung diseases including chronic obstructive lung disease and/or pulmonary fibrosis. The purpose of this protocol is to collect clinical data, blood, urine, and bronchoalveolar samples from smokers and non-smokers in an attempt to establish phenotypic clinical profiles that correspond to divergent pathways in the expression of such proteins as the transforming growth factor-beta1 (TGF-beta <=1). The information generated from this study will provide insight into the pathogenesis of smoking-related lung injury and potentially allow for the development of early therapeutic interventions.
The aim of this study is evaluate the clinical, hemodynamic and electrocardiographic responses during an inspiratory muscle training session during a single cardiopulmonary rehabilitation session program. An electrocardiogram will be continuously recorded and the heart rate (HR) and blood pressure (BP) will be evaluated before, during and immediately after a single inspiratory muscle training (IMT) session, consisting of two series of 15 cycles, with one-minute intervals between sets and an initial load of at least 30% of the initial maximal inspiratory pressure (MIP).
Shortness of breath (dyspnea) during exercise is a major source of distress and is a commonly reported symptom in patients with cystic fibrosis (CF). Due to the investigators' poor understanding of how dyspnea develops, there are no treatments that consistently reduce dyspnea in this population. The investigators aim to acquire a more comprehensive understanding of the physiological mechanisms of exertional dyspnea in CF patients. This study will likely identify an important physiological mechanism of dyspnea in CF and may contribute to the development and use of effective treatments to reduce dyspnea in this population. The central hypothesis is that the impaired tidal volume (VT) response during exercise in CF, in the setting of increased ventilatory demand will give rise to different qualitative descriptions of exertional dyspnea compared with healthy age and sex-matched controls. Specifically, CF patients will select "increased work and effort" as their dominant descriptor of dyspnea up to the VT inflection/plateau. Beyond this point, CF patient's dominant descriptor will become "unsatisfied inspiration." In contrast, healthy control participants will report "increased work and effort" throughout all phases of exercise and will not report "unsatisfied inspiration", even after the VT inflection/plateau.
