Filter by:The investigators assume that by analysis of different volatile organic compounds in the breath, using nanotechnology, the investigators will be able to identify a unique respiratory signature of different diseases including asthma, chronic obstructive pulmonary disease (COPD) and pulmonary hypertension.
The purpose of this study is to elucidate phenotypic, clinical, and genetic characteristics of Korean Nontuberculosis Mycobacteria (NTM) patients.
The purpose of this study is to evaluate the performance of AVAPS AE therapy in COPD patients during nocturnal ventilation.
The study will assess the long-term safety of the fixed combination product QVA149 versus placebo and a standard of care treatment (tiotropium) in Chronic Obstructive Pulmonary Disease (COPD) patients with moderate to severe airflow limitation.
COPD continues to be a cause of major morbidity for patients. Those patients who also have respiratory failure are at higher risk of exacerbations and death and have worse health related quality of life than similar COPD patients without respiratory failure. Treatment options in this group of patients have been limited and data to support the use of machines to assist breathing (non-invasive ventilators) in stable patients are limited. A major limitation of these devices has been patient acceptance and achieving sufficient control of sleep breathing disturbance. Currently devices are set at a fixed pressure to support the breathing throughout the night. The new software within the trial device will aim to better match the support provided by the machine to that needed by the patient. It is hoped that this may offer enhanced comfort as well as superior control of respiratory failure.
The purpose of this study is to generate a prospective database of all patients evaluated for diffuse parenchymal lung diseases to provide much needed data on the various disease aetiologies, incidence and prevalence rates, clinical and radiological presentations, pathologic correlations, disease progression and response to treatment, and final outcomes in this group of patients in Singapore.
The purpose of this study is to assess the feasibility and potential impact of an eight week program of meditation on expiratory time, anxiety and dyspnea in people with COPD.
The purpose of this study is to investigate to what extent patients with COPD, who have participated in physical training for 12 weeks, can maintain their physical activity behaviour and physical capacity on a long-term basis if they get a behavioural medicine intervention.
Several impairing factors contribute to physical limitation in chronic obstructive pulmonary disease (COPD) as deconditioning, muscle dysfunction and physical inactivity. The available literature clearly indicates that these therapeutic targets benefit from exercise training in patients with COPD and, currently, the key point is not whether patients should or not exercise, but which is the specific contribution of each exercise modality to this population. About this topic, the characteristics of a physical training program to be offered to patients have been a point discussed among researchers in this field, although recently the high-intensity training has been recognized as superior in comparison to the low-intensity training. Literature also indicates that, in order to change the sedentary lifestyle of patients with COPD, long-term training programs are indicated. However, a doubt still remains: if long-term programs are one of the key points to reduce physical inactivity, it is not yet clear whether it is necessary to include high-intensity exercises in that long-term program. If the duration is the only factor influencing the outcomes of the program, thus the intensity of training could be reduced, increasing the adherence of patients to the protocol. Based on this hypothesis, the aim of this study is to compare the effects of two physical training protocols in a long-term rehabilitation program (6 months) in patients with COPD: a high-intensity protocol (based on endurance and resistive training) and a low-intensity protocol (based on callisthenic and breathing exercises training). It is expected that the results of this study contribute to the scientific literature by demonstrating whether low- and high-intensity training contribute equally to change the sedentary lifestyle of patients after a long-term exercise program.
Background: In chronic obstructive pulmonary disease, the prognosis for patients who have survived an episode of acute hypercapnic respiratory failure due to an exacerbation is poor. Despite being shown to improve survival and quality-of-life in stable patients with chronic hypercapnic respiratory failure, long-term noninvasive ventilation is controversial in unstable patients with frequent exacerbations, complicated by acute hypercapnic respiratory failure. In an uncontrolled group of patients with previous episodes of acute hypercapnic respiratory failure, treated with noninvasive ventilation, we have been able to reduce mortality and the number of repeat respiratory failure and readmissions by continuing the acute noninvasive ventilatory therapy as a long-term therapy. Methods: Multi-center open label randomized controlled trial of 150 patients having survived an admission with noninvasive ventilatory treatment of acute hypercapnic respiratory failure due chronic obstructive pulmonary disease. The included patients are randomized to usual care or to continuing the acute noninvasive ventilation as a long-term therapy, both with a one-year follow-up period. End points: The primary endpoint is one-year mortality; secondary endpoints are time to death or repeat acute hypercapnic respiratory failure, number of readmissions and repeat acute hypercapnic respiratory failure, exacerbations, dyspnea, quality of life, sleep quality, lung function, and arterial gases.
