Filter by:The definition of obstructive airway disease is a ratio of the forced expiratory volume in one second (FEV1) to the forced vital capacity (FVC) of less than 0.7, which includes conditions such as chronic obstructive pulmonary disease, asthma, lymphangioleiomyomatosis, and bronchiolitis obliterans syndrome. For example, lung obstruction adversely affects many aspects of a patient's health, such as lung function and exercise capacity. Pulmonary rehabilitation is widely used in patients with obstructive airway disease, and the prescription of pulmonary rehabilitation depends on exercise capacity parameters such as peak oxygen uptake (peak VO2), peak workload, and anaerobic threshold. However, patients often have difficulty achieving training goals due to severe dyspnea during exercise. Dynamic hyperinflation is a common cause of dyspnea during exercise in patients with obstructive airway disease. Investigators aim to alleviate breathlessness by reducing dynamic hyperinflation, making it easier to achieve training goals. Methods to reduce dynamic hyperinflation include pursed lip breathing, reducing breathing rate to prolong expiratory time, using bronchodilators, and undergoing lung volume reduction surgery. Among these methods, reducing breathing rate to prolong expiratory time may be the most feasible, and investigators aim to change the rhythm and pace of breathing by adjusting the pedal rate of cycling exercise. The pedaling rate is typically set at 60 revolutions per minute. The European Respiratory Society recommended a pedal rate range of 40-70 revolutions per minute in 2019. There is still no consensus on the relationship between pedal rate and respiratory rate. This prospective observational study, using a crossover design, aims to investigate the effects of pedal rate during exercise testing on dynamic hyperinflation and exercise capacity in patients with obstructive airway disease.
Primary Objective: To evaluate the pharmacokinetics of Tiotropium Bromide Inhalation Powder (Strength:18 mcg; manufactured by Chia Tai Tianqing Pharmaceutical Group Co. Ltd) and reference products Tiotropium Bromide Inhalation Powder (Spiriva®, Handihaler®, Strength: 18mcg, manufactured by Boehringer Ingelheim Pharmaceuticals, Inc) by oral inhalation of single dose in healthy participants under fasting conditions.
This work aims to evaluate whether the segmentation of vowel recordings collected from patients diagnosed with COPD and healthy control groups can increase the classification precision of machine learning techniques.
The goal of this clinical trial is to compare the acute bronchodilator effect of pMDI formed Ipratropium / Levosalbutamol 20 mcg / 50 mcg fixed dose combination or pMDI formed Salbutamol 100 mcg Inhaler and Ipratropium 20 mcg Inhalation Aerosol in combination in stable moderate-severe-very severe COPD patients.
This work aims to evaluate whether voice recordings collected from patients diagnosed with COPD and healthy control groups can be used to detect the disease using machine learning techniques.
This cohort study aims to use the open-source RADAR-base mHealth platform to collect and analyze datasets associated with lung disease. This will include continuous data collected from wearable devices (e.g. heart rate, oxygen saturation, respiratory rate), including pulse oximeters, spirometer, mobile phones, digital tests, and smart phone symptom questionnaires.
This is a 12-week (with an extension to 52 weeks in a subset of participants) study comparing the safety of BGF MDI HFO twice daily (BID) with BGF MDI HFA BID in participants with moderate to very severe COPD.
This study aims to evaluate the impact of a specific oral probiotic blend on the quality of life of adults with respiratory conditions.
This study aims to evaluate the comparative risk of dementia/Alzheimer's disease onset between patients treated with medications that target specific metabolic pathways and patients treated with alternative medications for the same indication.
Chronic obstructive pulmonary disease (COPD) is characterized by persistent respiratory symptoms (including breathlessness, cough, and sputum production), which has a substantial impact on health-related quality of life (HRQoL). Medical treatment of COPD aims to reduce these symptoms, reduce exacerbations, and improve patients' ability to perform exercise and daily activities. TRIXEO is a triple therapy indicated as a maintenance treatment in adult patients with moderate-to-severe COPD who are not adequately treated by a combination of an inhaled corticosteroid and a long-acting beta2-agonist or combination of a long-acting beta2-agonist and a long-acting muscarinic antagonist. The RECORD study is a prospective, non-interventional study to be conducted in the United Kingdom (UK) and Germany. The study aims to generate data to describe the real world effectiveness of TRIXEO for patients with COPD who receive TRIXEO in routine clinical practice. It also aims describe patients HRQoL, physical activity and treatment satisfaction, and will explore patients' sleep quality and adherence to inhalers in the real-world. This data may provide important information for practicing physicians. The study will include approximately 500 patients with moderate to severe COPD from approximately 50 sites (including hospitals and GP practices) in Germany. Patients eligible for TRIXEO therapy may be enrolled by their treating physicians. The decision to treat with TRIXEO must be independent of the study and made by the treating physician according to the patients' medical need and local routine clinical practice. Patients' data will be collected for 12 months after starting therapy with TRIXEO. Demographic and clinical data will be extracted from patients' health care records. Patient reported outcomes will be collected remotely by asking patients to answer questionnaires on health status and HRQoL, physical activity, sleep quality, treatment satisfaction, and inhaled medication adherence through electronic surveys.
