Active clinical trials for "Pulmonary Disease, Chronic Obstructive"

The VitaBreath (Philips, Respironics) is a portable, handheld, battery powered, non-invasive ventilation device, that has been shown to reduce activity-related shortness of breath in patients with COPD. The VitaBreath device delivers 18 cmH2O inspiratory and 8 cmH2O expiratory pressures, but can only be used during recovery periods. A previous study (REC: 17/NE/0085) showed that use of the VitaBreath device during the recovery periods interspersing successive exercise bouts enhances exercise tolerance and reduces breathlessness compared to pursed lip breathing in patients with COPD. This was attributed to faster recovery from exercise-induced dynamic hyperinflation, assessed by volitional inspiratory capacity manoeuvres using a spirometer. However, inspiratory capacity manoeuvres are effort dependent, thus limiting the number of repetitions the patient can perform during exercise. In addition, investigation of the direct effect of the application of the VitaBreath device on dynamic hyperinflation was not possible due to the need to employ a spirometer for assessing inspiratory capacity. Optoelectronic plethysmography (OEP) allows continuous non-invasive assessment of end-inspiratory and end-expiratory volumes of the thoracoabdominal wall and its compartments, thereby facilitating assessment of dynamic hyperinflation on a breath-by-breath basis without the necessity to breathe via a spirometer. Unfortunately, OEP technology was not available at the time of our previous study. The investigators will use OEP to provide accurate breath-by-breath volume measurements during exercise and recovery to evaluate whether the VitaBreath device reduces total and compartmental thoracoabdominal wall volumes compared to the pursed lip breathing technique. Furthermore, the investigators will investigate the effect of use of the VitaBreath device on respiratory muscle activation and respiratory muscle oxygenation using OEP technology in conjunction with electromyography (EMG) and near inferred spectroscopy (NIRS), respectively to appreciate how the application of the VitaBreath device impacts on the operation and energy demands of the respiratory muscles as compared to control pursed lip breathing. The investigators hypothesised that the use of the VitaBreath device during the recovery periods interspersing successive exercise bouts will reduce the magnitude of dynamic hyperinflation in a greater extent compared to the pursed lip breathing technique.

This Dietary Intervention is being done to evaluate the feasibility of a food voucher program and dietary counseling to increase consumption of healthy fatty acids (omega-3) in individuals with Chronic Obstructive Pulmonary Disease (COPD).

The most common symptom of chronic obstructive pulmonary disease (COPD) is shortness of breath and causes a decrease in the patient's quality of life. The best way to relieve shortness of breath is inhaler therapy. However, it is known that patients frequently apply this treatment incorrectly. The aim of this study is to determine the effects of breathing exercises and inhaler training for COPD patients on the severity of dyspnea and life quality. For this, two patient groups with a total of 67 people were included in the study. While one group was trained on inhaler drug use, the other group was taught breathing exercises in addition to the inhaler drug use training. Patients were asked to continue the practices they learned regularly for 4 weeks. At the end of the study, it was observed that shortness of breath decreased and the quality of life increased in both patient groups.

The objective of the proposed study is to evaluate the bioavailability of CHF6001 after inhaled administration and to characterize the mass balance and route of elimination of CHF6001 in human along with its relevant metabolites.

It has been demonstrated that consequences of malnutrition affect a situation of risk and have negative effects on the evolution of chronic obstructive pulmonary disease (COPD), accompanied by higher morbidity and mortality. The impact of malnutrition on the respiratory system affects the respiratory muscles, the lung parenchyma, and the immune system. In summary, the risk of complications can lead to a worsening of the quality of life of the COPD patient. Also, dyspnea as the main symptom of COPD is the one that produces the greatest loss of quality of life, especially in older patients. The components of our authorized food supplement improve the quality of life of the patient. These components maintain the strength and energy of the patient, help the body to recover and regain its optimal state, help improve the immune system, help reduce the side effects of therapies associated with the control or cure of cancer and help correct nutritional deficiencies. This is the reason why this experimental study aims to improve the quality of life in patients with COPD with a CAT score>15.

The aim of this study is to investigate the effects of a walking program on exercise capacity and quality of life in patient with COPD. Method: Patients with COPD were randomly assigned to pedometer group (PG) or control group (CON). Subjects in PG walked to target steps daily with pedometer for 6 weeks. Before and after the program, the following measurements were performed: pulmonary function test (PFT), daily steps, Six-Minute Walk Test (6MWT), COPD Assessment Test (CAT), and quality of life questionnaire (SF-12).

An average of 4.8 million journeys are made on the London Underground every day and as the 'Tube' has elevated airborne particulate matter concentrations compared to ambient air, this raises concern about the potential health impact of this environment. This study explores the health effects of particulate matter from the London Underground on patients with COPD and healthy volunteers. Patients with COPD and healthy participants will be invited to undertake a set 90 min journey on the London Underground, and on a separate occasion (3-8 weeks apart), a 90 min journey on the London Overground (as a proxy for a clean air London area while maintaining other aspects of a train journey). A series of clinical, physiological and inflammatory data will be collected before, during and after (at different time points) each of the sessions in order to compare their response in relation to exposure and/or to disease status.

The 1-minute sit to stand (1-min STS) test is a standardized test which is used to examine exercise capacity in patients with chronic obstructive pulmonary disease (COPD). The chair seat height used is standardized to 46-48 cm. Using a standard seat height for all patients - irrespective of their body height - may lead to invalid estimates of functional exercise capacity. The objective of this study is to assess whether there is a difference in repetitions during the 1-min STS test if the seat height is adjusted to 90° knee joint angle or the standard height chair of 46 cm is used.

The primary purpose of this study is to compare and assess the immediate and long-term effects on pulmonary rehabilitation training with the usage of HFNC or conventional oxygen therapy device. The hypotheses was, with high flow nasal cannula usage while exercising, the physiological outcome measurements would be better than conventional oxygen therapy device. Also, the usage of HFNC can immediately increase patient's exercising endurance and decrease dyspnea caused by exercising.

This study will develop and experimentally test the efficiency of a neurofeedback training protocol vs. varenicline use for smoking cessation.
