Filter by:Influenza disease causes significant morbidity and mortality in the Unites States each year. Although influenza can cause morbidity in otherwise healthy individuals, adults with chronic lung disease have significantly increased rates of hospitalization from influenza-related illnesses compared to healthy adults. Influenza vaccination is the primary means of preventing influenza disease. Annual influenza vaccination is recommended for all individuals 6 months of age and older in the United States. Influenza vaccination rates are sub-optimal, however. Patient reminder/recall has been shown, in multiple studies across a variety of age groups and health conditions, to increase immunization rates. However, the effectiveness and cost-effectiveness of different types of reminder/recall has not been well-studied, particularly in adults. In the fall of 2012, the Population and Prevention Services (PPS) Department at Kaiser Permanente Colorado (KPCO) is using 3 different reminder strategies for influenza vaccination among adults with asthma and chronic obstructive pulmonary disease (COPD). The objective of this study is to provide a rigorous evaluation of which strategy is more effective and more cost-effective, to promote influenza vaccination.
Conventional approaches to relieve dyspnea (respiratory discomfort) in chronic obstructive pulmonary disease (COPD) have focused on improving respiratory motor drive (e.g., hyperoxia) and/or dynamic respiratory mechanics (e.g., bronchodilators). Although these approaches yield meaningful symptom improvements there remains many COPD patients incapacitated by dyspnea. Accumulating evidence suggests that abdominal binding (AB) is a potentially novel method of improving respiratory muscle function and, by extension, dyspnea and exercise tolerance in COPD. Thus, the purpose of this randomized, cross-over study is to test the hypothesis that AB improves exertional dyspnea and exercise tolerance in symptomatic patients with COPD by improving dynamic respiratory muscle function. To this end, the investigators will examine the effects of AB on detailed assessments of baseline pulmonary function (spirometry, plethysmography), dyspnea (sensory intensity & affective responses), neural respiratory drive (diaphragm EMG), contractile respiratory muscle function (esophageal, gastric & transdiaphragmatic pressures), ventilation, breathing pattern and cardiometabolic function during symptom-limited constant load cycle exercise (75% Wmax) in 20 patients with GOLD stage II/III COPD.
The investigators designed the current study with the main objective of determining whether Whole Body Vibration Training (WBVT) alone improves muscular force and/or modifies the functional capacity parameters in severe Chronic Obstructive Pulmonary Disease (COPD) patients referred to a rehabilitation programme.
It is a phase IV clinical trial: longitudinal, prospective, evaluator-blind, randomized into 2 groups of patients with chronic obstructive pulmonary disease (COPD). The intervention group was based on the administration of roflumilast 500 mcg per day on alternate days (roflumilast 500μg eod) for 2 weeks (phasing). In the control group assigned to undertake the treatment according to the standard dosage (roflumilast 500μg od). The patient monitoring will be done by one of the sub-investigators fully independent team that started the medication keeping the pattern masking by single blind, and since it aims to assess the frequency of adverse events (AEs) in both groups were collected systematically different AEs and their characteristics at 15 days (V1), and from that moment a month (V2) and 2 months (V3). Likewise, other data collected (functional demographic, comorbidities, home treatment, anxiety and depression and quality of life). The purpose of this study is to assess whether the administration of roflumilast by a gradual pattern varies the incidence of discontinuations due to adverse events when compared with the usual dosage.
The purpose of this clinical trial is to demonstrate hyperpolarized xenon (HXe) as a medical imaging drug (agent) for Magnetic Resonance Imaging (MRI) of the human lung ventilation.
The aim of this study was to evaluate the effect of listening to ambient music on the perceived exertion rate during pulmonary rehabilitation for chronic obstructive pulmonary disease patients.
Chronic Obstructive Pulmonary Disease (COPD) is a progressive respiratory (lung) disease that makes it harder to breathe over time. To date, there is no cure for COPD, but it can be managed when diagnosed and proper medical care is provided. The purpose of this study is to determine if diagnosis and guided therapy with the use of spirometry is related to better patient outcomes (the condition of a patient's health) compared to usual care which may or may not include the use of spirometry. Spirometry is a standardized test used in medical practice that measures how much air your lungs can hold and how forcefully you can breathe out. For this study, the investigators will compare two groups: 1) intervention (treatment) group and 2) usual care group (control). The intervention group will have a spirometry test and the results will be provided to the primary care physician. The usual care group will not initially have a spirometry test. Both groups will be followed for outcomes.
Chronic obstructive pulmonary disease (COPD) is characterised by airflow limitation that is not fully reversible, and is usually progressive and associated with an abnormal inflammatory response of the lungs to noxious particles or gases, most commonly cigarette smoking. The disease affects not only the large central airways but also the small, more peripheral airways deeper into the lung, defined as less than 2 mm in diameter. Besides medical treatment, physiotherapy plays a major role in treatment and various methods have been suggested to remove airway of secretions. The flutter is a simple and small device shaped like a pipe that creates a positive expiratory pressure (PEP) and high frequency oscillation when the expired air passes through it. These vibrations are thought to mobilise airway secretions facilitating their clearance and improving breathing. Standard blowing tests, like spirometry, where patients blow forcedly into a machine, have previously been used to investigate the efficacy of flutter devices. However, spirometry assesses the damage of larger airways but not small airways, also known as the "silent zone" which, crucially, are specifically damaged in COPD. In this study the investigators hypothesise that because the flutter helps clear the airways from the excessive thick mucus produced by COPD patients, these patients may find it easier to breathe and have lower resistance to moving air in and out of their lungs. The main objective of this study is to compare the effect of a flutter or a sham device on small airways damage using impulse oscillometry (IOS), a non-invasive method that, contrary to other common blowing tests, measures small airway resistance during normal breathing. In addition, because COPD is characterised by inflammation, the investigators would also like to measure a gas the patients blow out, nitric oxide (NO) the levels of which reflect airway inflammation. This will give to investigators an insight into the relationship between airway inflammation and small airway function.
Chronic Obstructive Pulmonary Disease (COPD) is a chronic condition. Its evolution can be aggravated in some periods by an increase of the symptoms (above all the cough, the dyspnoea and the quantity of sputum purulence). This is known as exacerbation and it is the most frequent cause of hospital stay, urgences services and death in COPD. A physiotherapy program is carrying out in patients attending to the Hospital because of an exacerbation. The hypothesis of this study is that a physiotherapy program added to a medical treatment increase the ventilatory function, the physiques variables, decrease depression and anxiety and improve the quality of life. Additionally, it is going to be assessed the effect of physiotherapy in time using phone calls and visits to the patient's home.
The study hypothesis is chest wall muscle stretching increase distribution of volume variation of thoracoabdominal wall and reduce electromyographic activity of respiratory muscles in patients with Chronic Obstructive Pulmonary Disease.
