Filter by:Chronic Obstructive Pulmonary Disease (COPD) is projected to be the fifth leading burden of disease worldwide by the year 2020. An acute exacerbation of COPD (AECOPD) is defined as an acute event characterized by a worsening of the patient's respiratory symptoms that requires a modification in the medication. AECOPD are frequent (mean of 1-4 exacerbations each year). It increases in frequency with the severity of the disease. The objective of this study is to examine whether a physical therapy intervention can reduce impairment in patients with COPD during hospitalization due to an acute exacerbation.
Assessment of the effect and safety of noninvasive positive pressure ventilation for severe stable chronic obstructive pulmonary disease
This study aims to analyze the impact of a brief psychological support intervention in the promotion of the adherence to Non Invasive Ventilation (NIV) among people with Chronic Obstructive Pulmonary Disease (COPD). The investigators expect to see a positive impact of this intervention on both physical and psychological well-being, and consequently, a reduction of health costs.
Chronic obstructive pulmonary disease (COPD) is characterized by the obstruction is not fully reversible airway, where the severity of the disease and the prognosis is not determined solely by changes in lung function. Pulmonary rehabilitation is a multidisciplinary program of care for patients with chronic respiratory diseases, individually designed to optimize physical and social performance and autonomy of these patients, promoting improvement in functional exercise capacity, quality of life, reducing dyspnea, frequency and duration of hospitalizations and reduce the frequency of exacerbations of the disease. The overall objective of the research is to evaluate the effects of pulmonary rehabilitation program on exercise capacity, lung function, quality of daily life and reduction of dyspnea in patients with COPD. A study type randomized, open-label trial following the recommendations of the CONSORT (Consolidated Standards of Reporting Trials) will be held. The study will be conducted at the Clinic Physiotherapy Course of the School with a sample of 58 patients. The intervention will be performed sessions three times a week for 16 weeks (8 weeks for assessment and 8 weeks for adaptation and (pulmonary rehabilitation training). The PR (pulmonary rehabilitation) will last 60-120 minutes each.O group A (control) will receive treatment of traditional pulmonary rehabilitation and without resistive training for upper limb (UL) and group B will receive the same treatment control with additional training of upper limb strength.
In this study the investigators aim to investigate the extent to which in patients with chronic obstructive pulmonary disease narrowing of the vocal cords causes a positive pressure within the airways thus improving airflow and lung function. This information will be captured in the upright and lying down positions and an estimate of the magnitude of the effect will be formed by offsetting the pressure by asking the patients to breathe using a commercially available device used to treat sleep apnoea called a CPAP machine. This is an observational study in which the observation of laryngeal aperture, and mouth and oesophageal pressure at differing levels of applied CPAP will be recorded for analysis in patients with COPD and in normal subjects without COPD. All will have the same measurements, observations, and interventions to allow us to observe and measure pressure, laryngeal aperture, and airflow .
The primary aim of this study is to investigate the incidence of falling in a cohort of patients with chronic obstructive pulmonary disease (COPD) referred to a pulmonary rehabilitation program and to verify the risk factors. The secondary aim is to verify whether available balance assessment tools are feasible in clinical practice and which tools and values can best predict falls in people with COPD.
Disordered iron metabolism characterizes an important determinant of impaired exercise tolerance and work capacity. Iron-deficiency anemia commonly features impaired aerobic capacity caused by decreased oxygen carrying capacity, and has been associated with a negative effect on dyspnea and walking distance. Apart from that, iron deficiency without anemia was shown to affect endurance and energetic efficiency via decreased tissue oxidative capacity. Consequently, depleted iron stores could be capable of causing fatigue, breathlessness and impaired exercise tolerance, which are common features of chronic cardiopulmonary diseases like chronic heart failure (CHF) and COPD (Chronic Obstructive Pulmonary Disease). Indeed, a current surge of interest aimed at potential underlying determinants in CHF and COPD independent of the primarily disordered organ. Recent studies identified iron deficiency without anemia as an independent factor of reduced exercise intolerance in CHF as well as in COPD. Moreover, intravenous iron application significantly improved exercise capacity in CHF patients with iron deficiency in presence as well as in absence of anemia. Comparable to CHF, the daily living of patients with COPD is compromised by impaired exercise tolerance. However, airflow limitation, as the foremost characteristic of COPD shows only weak associations with exercise capacity. In line with that, exercise capacity showed no remarkable improvement in lung transplant recipients, underlining the presence of systemic determinants of limited exercise tolerance like iron deficiency. The investigators showed that iron deficiency is present in 50% of stable COPD patients (unpublished data), which is according to recently published data. The investigators presume that iron deficiency contributes to limited exercise capacity in COPD patients. Thus, the aim of this study is to determine whether iv iron is associated with increases exercise capacity in COPD. Therefore the investigators hypothesize that filling up depleted iron storages will increase exercise capacity, measured by the 6-MWT (Minute Walking Test).
For patients with emphysema, lung volume reduction by insertion of endobronchial valves could be an expedient approach to improve the diaphragm function and the strength of breathing muscles. Therefore in the present study investigators intend to examine, whether the lung volume reduction by valves might improve the physical capacity and the quality of life.
