Active clinical trials for "Lung Diseases"

This study is designed to provide preliminary information regarding how to improve pulmonary rehabilitation for persons with chronic obstructive pulmonary disease (COPD). Pulmonary rehabilitation is an exercise program for COPD patients that is recommended and benefits some, but not all, patients. The question being studied in this trial is whether walking on an incline might be better than walking on faster on a flat surface in training muscles so that patients might be less short of breath with exercise.

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.

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).

The purpose of this study is to compare 12-weeks of virtual multidisciplinary programming provided at three levels of support intensity to determine impacts on clinical outcomes, acceptability, and cost amongst outpatients with cancer, liver disease, or lung disease. Participants will be randomized to one of three groups: (i) standard care, (ii) a personnel-light app-based intervention, (iii) a personnel-intensive app-based intervention. Participants randomized to standard care will receive exercise and nutrition resources as well as a Garmin watch. Participants in the experimental groups will receive standard care, plus a 12-week multidisciplinary app-based personalized program involving 12 weeks of exercise programming and 10-weeks of nutrition programming. Participants in study group 3 will receive additional one-on-one care. The Research Ethics Board at the University of Alberta has approved this study. The protocol will measure patient-related outcome measures including physical function, quality of life, social isolation, and anxiety, as well as measures of acceptability and cost. 216 participants will take part in this study (n=72 per arm). Analyses: fitness testing and patient-reported outcomes will be administered before and after the intervention. Fitness and patient-reported outcomes will be compared using linear mixed models with random effects. App acceptability will be compared between groups using Chi-Square.

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.

Develop appropriate individual programs for patients to implement lung rehabilitation safely and effectively.

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.

The clinical course of chronic obstructive pulmonary disease (COPD) is associated with recurrent episodes of exacerbation that results in respiratory failure. The treatment of respiratory failure is supportive and involves inhalation bronchodilators along with systemic steroids. In few cases the management of acute respiratory failure requires positive pressure ventilation (non-invasive or invasive). The use of NIV in acute exacerbation of COPD has resulted in significant reduction in morbidity and mortality. Although pressure support ventilation (PSV) allows the patient to influence the breathing pattern, ventilator-cycling criteria may worsen the patient-ventilator interaction, and severe asynchronies occur in up to 43% of patients undergoing NIV for ARF. Adaptive support ventilation (ASV) is a newer mode of ventilation that incorporates feedback mechanisms and thus provides a stable minute ventilation. We hypothesize that the use of ASV as a mode during ventilation using NIV in patients with acute exacerbation of COPD may result in reducing the duration of ventilatory support, need for intubation, and duration of intensive care unit (ICU) and hospital length of stay, when compared with PSV mode of NIV ventilation.
