Filter by:Lack of tolerance to the treatment, makes the interface choice for non-invasive ventilation (NIV) one of the key factor. To date the helmet is rarely used in Acute Hypercapnic Respiratory Failure (AHRF), because of its large dead space, despite in hypoxic respiratory failure, it is largely employed as a "rotating" strategy when the facial mask is poorly tolerated. In a multicenter randomized controlled trial, the investigators will compare the clinical efficacy of a new helmet designed to specifically improve the performance in chronic obstructive pulmonary disease (COPD) versus a full face mask during an episode of AHRF.
Chronic obstructive pulmonary disease (COPD) stands out among chronic diseases with its high and rising prevalence and mortality, poor quality of life, high re-hospitalization rates and societal burden of care. Current therapeutic and management practices are generally met with limited success. Research in recent years have highlighted the high level of psychiatric co-morbidity in COPD patients, and the major prognostic significance of anxiety/depression in COPD outcomes such as re-hospitalization, smoking cessation, quality of life, and survival. This suggests that addressing psychiatric and psycho-social aspects of care prominent in COPD patients may have strongly positive impact on outcomes, but the available evidence of effectiveness is limited. The primary aim of the proposed research is to evaluate the effectiveness of a holistic disease management paradigm of psychiatric liaison consultation (CL) that integrates psychiatric and respiratory care to improve outcomes for COPD patients. This integrated psychiatric consultation liaison (IPCL) management paradigm includes the routine screening and structured collaborative care of anxiety and major depressive symptoms and depressive/anxiety disorder in COPD patients. We postulate that the IPCL care paradigm would reduce mood symptoms, increase smoking quit rates, reduce symptom burden and functional disability, and improve quality of life, while reducing rehospitalization, emergency department (ED) and unscheduled physician visits. A secondary aim is to evaluate its cost effectiveness by concurrently collecting resource utilization data.
The aim of this study is to determine whether respiratory disease exacerbations (a sudden worsening of symptoms) can be predicted by variables that are monitored by non-invasive ventilators (small machines that assist breathing) in patients requiring long term home ventilation. The investigators hypothesise that acute exacerbations of patients with respiratory disease and ventilatory failure will be predicted by changes in the respiratory variables monitored and stored by ventilators during chronic home ventilator use.
The aim of the study is to investigate the quality of prehospital emergency care in acute respiratory emergencies, when paramedics are supported telemedically by an EMS physician.
The purpose of this study is to develop and evaluate the usefulness of magnetic resonance imaging (MRI) using inert perfluorinated gases mixed with oxygen for regional assessment of pulmonary function. The proposed study seeks to determine regional qualitative and quantitative lung function information in the context of the clinical trajectory of chronic obstructive pulmonary disease (COPD) defined by the cross sectional cohort component. In the case of these perfluorinated (PFx)/oxygen mixtures, the availability of multi-liter quantities allows for wash-in/wash-out image acquisition and analysis allowing direct measures of gas trapping in a manner not easily achieved with any existing modality.
Highly active antiretroviral therapy (HAART) has considerably improved survival of HIV-infected patients. Opportunist diseases and cancers linked to immunodepression have largely regressed. Challenge is now the management of cardio-vascular diseases, nephrologic, neurologic, osteo-articular diseases, chronic hepatitis and cancer no linked to immunodepression. All this comorbidities are more reported in HIV-infected patients than in general non-HIV infected patients. Those are directly linked to the effect of chronic HIV-infection on ageing, metabolic effects of HAART, and way of life characterising this population. Chronic obstructive pulmonary disease (COPD) results from tobacco consumption. Bronchial chronic infection, immunity, and ageing are also involved in the physiopathology of COPD. This disease has never been evaluated in a large prospective cohort of HIV-infected patients whereas there is a known increase of tobacco consumption and pulmonary infection in this population regardless to the general population. Characterisation of COPD disease in HIV patients will allow us to make an hypothetic epidemiological link between HIV- HAART and COPD independently of tobacco consumption, and to study different physiopathologic hypothesis evocated in COPD genesis, like an accelerate pulmonary ageing.
The purpose of this study was to observe the Efficacy and safety of 400 μg twice daily of aclidinium bromide vs. placebo when administered to patients with moderate to severe chronic obstructive pulmonary disease (COPD).
To compare the efficacy, safety and pharmacokinetics of QMF149 delivered via Concept1 to salmeterol xinafoate/fluticasone propionate delivered via Accuhaler in adult patients with COPD
Objective: To characterize FeNO levels that may be indicative of eosinophilic airway inflammation in patients with chronic obstructive airways disease Number of participants: Approximately 200 subjects will be enrolled Reference product: NIOX MINO® Instrument (09-1100) Performance assessments: Fractional Exhaled Nitric Oxide (FeNO) Measurements will be performed according to the "Perform FeNO Measurement" guidelines on page 7 of the NIOX MINO® User Manual Safety assessments: The Investigator is responsible for the detection, reporting, and documentation of events meeting the definition of an Adverse Event (AE) and/or Serious Injuries as provided in this clinical investigation plan from the time that informed consent has been provided and during the study period Criteria for evaluations: This is an observational, pilot study and there are currently no plans for a formal statistical analysis. Information gained from this study may used to design subsequent studies in patients with chronic obstructive airways disease. Information collected will be summarized in a clinical study report but will not be subject to formal hypothesis testing
The investigators hypothesize that education will improve exercise capacity, symptoms and quality of life in patients with chronic obstructive pulmonary disease (COPD). In addition, the investigators are interested in determining how education might alter various chemicals in the blood and exhaled breath that reflect inflammation in the lungs and the body as a whole. The investigators plan to enroll 42 patients into this study, with half of them participating at each of the two sites, Vermont Lung Center at the University of Vermont in Burlington, Vermont, and at Baylor College of Medicine in Houston, Texas. Participants will undergo a series of measurements and tests at the beginning of the study, receive formal education about COPD over the next 2 weeks, return at 6 weeks for a brief refresher session, and finally return after 12 weeks for repeat measurement and testing as was done at the beginning. Participants will be asked to keep a diary of symptoms, medication, and exercise during the study.
