Vitamin D3 supplementation doen not change lung functions and exercise tolerance in vitamin D3 deficient ACO patient was the null hypothesis of the research.
In the presented study, autonomic function as well as risk for atrial fibrillation will be assessed to characterize the relation between risk of atrial fibrillation and autonomic function.
The aim of the study is to investigate the efficacy of upper limb exercise training in Chronic Obstructive Pulmonary Disease (COPD) patients. For the purpose of the study, a controlled trial will be conducted within Respiratory Clinic of Nicosia General Hospital. The sample will be divided in two groups. The intervention group will participate in a pulmonary rehabilitation program which includes upper and lower extremities exercises, with addition of arm ergometer. The second group (control group) will participate in the same program but without arm ergometer training. The study's hypothesis is that the intervention group will improve the outcome measures significantly better than the control group.
The purpose of conducting this study is to obtain PK data of Beclometasone Dipropionate (BDP)/Beclometasone-17-MonoPropionate (B17MP), Formoterol Fumarate (FF) and Glycopyrronium Bromide (GB) after inhalation of CHF 5993 in Japanese as well as Caucasian healthy subjects under the same setting.
Inhaled corticosteroid (ICS)/long-acting β2-agonist (LABA) combination is commonly prescribed to treat COPD; we will perform a retrospective analysis on the effect of adding a long-acting muscarinic receptor antagonist (LAMA) to ICS/LABA combination in COPD.
Our overall research goal for this project is to create a wearable device and mobile application, appealing to patients with Chronic Obstructive Pulmonary Disease (COPD), which provides them with appropriate self-management tools and detects AECOPDs early to permit prompt treatment and prevent severe exacerbations requiring hospitalization.
This study will assess the within-day variation of blood eosinophils in patients with Chronic Obstructive Pulmonary disease (COPD) in stable state and determine if there is a correlation between the blood eosinophils and certain clinical parameters.
The VitaBreath (Philips, Respironics) is a portable, handheld, battery powered, non-invasive ventilation device, that has been shown by our group to reduce activity-related shortness of breath in patients with COPD. It delivers 18 cmH2O inspiratory and 8 cmH2O expiratory pressures, but can only be used during recovery periods. Our 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.
Scientific research focuses on "eosinophilic inflammation" as it seems to guide the therapeutic regimen in patients with asthma and COPD. The primary objective of this prospective trial is to evaluate which parameter(s) best reflects eosinophilic inflammation by correlating tissue eosinophils (endobronchial biopsy, protected specimen brush sampling) with FeNO, peripheral blood eosinophils, and eosinophils in the bronchoalveolar lavage of patients with obstructive pulmonary disease.
Chronic Obstructive Pulmonary Disease (COPD) is characterized by chronic airflow limitation, a qualification of impairment of respiratory muscle function, including hyperinflation and muscle weakness. Thus, pulmonary rehabilitation is indicated for patients and is recommended for even the most severe cases. However some patients do not conclude conventional rehabilitation protocols, due to exercise intolerance, are then an electrical estimation and muscle training respiratory adjuvant treatments for patients. and little has been explored about the effects and methodologies of using transcutaneous electrical diaphragmatic stimulation (TEDS) in healthy subjects. The objective of this study on stage I is to evaluate the acute effect of transcutaneous electrical diaphragmatic stimulation on respiratory muscle strength, cardiac variability, thickness, resistance, mobility and diaphragmatic activation comparing different frequencies of electrical stimulation in healthy individuals.The objective of this study on stage II is to evaluate the effects of transcutaneous electrical diaphragmatic stimulation, compared to inspiratory muscle training (IMT) on respiratory muscle strength, lung function, thickness and diaphragmatic function in patients with exacerbated chronic obstructive pulmonary disease. The study was approved by the Research Ethics Committee of the Hospital de Clinicas of Porto Alegre (CAEE: 80271517.2.0000.5327).
