Active clinical trials for "Lung Diseases, Obstructive"

The purpose of the study is to examine the hypothesis test that probiotics will reduce the frequency of exacerbation in patients with COPD.

Aims and objectives: To determine the effect of foot bath on sleep quality and fatigue level in patients with chronic obstructive pulmonary disease (COPD). Background: İnsomnia and fatigue are one of the most common symptoms in people with COPD and adversely affects their activities of daily living. Design: This study was conducted as a nonrandomized controlled trial. Methods:The study sample comprised 70 patients who met the inclusion criteria.Data were collected with Patient Information Form, Pittsburgh Sleep Quality Index and Piper Fatigue Scale. Intervention group; The 30-day foot bath was administered for 10 minutes before bedtime, while no control was performed in the control group. The Pittsburgh Sleep Quality Index (PUKI) and the Piper Fatigue Scale were administered in both groups at the beginning of the service (first follow-up) and four weeks later (second follow-up) at the outpatient clinic. Conclusions: The foot bath by individuals with COPD was determined to significantly improve the participants'levels sleep quality and fatigue.

COPD is the fourth leading cause of death in the world and is the only one of the top five illnesses whose death rate is still increasing. It is mainly caused by smoking. Greece has a higher prevalence and death rate for COPD than many other countries in Europe. The disease is incurable so treatment is aimed at alleviating symptoms and slowing progression. Despite maximal medication and strategies such as pulmonary rehabilitation and home nurse support, many patients remain vulnerable, socially isolated and report difficulty in accessing their local health services. Research has shown that patients have worsening symptoms for an average of three to four days before they are admitted to hospital with an exacerbation of COPD. This suggests a window of opportunity to intervene. Early warning and contact via innovative technology may treat symptoms earlier, improve patient confidence / quality of life and simultaneously reduce health care visits or admissions. However, there is a large gap between the postulated and empirically demonstrated benefits of electronic Health Technologies. In addition, there is a lack of robust research on the risks of implementing these technologies and their cost-effectiveness has yet to be demonstrated, despite being frequently promoted by policymakers as if this was a given issue. In addition, the evidence-base for telehealth is not well-reported in peer reviewed journals and hence there continue to be difficulties experienced in convincing clinicians, hospital managers and stakeholders that investment in such technologies will enable reductions in other aspects of healthcare delivery over time. This project attempts to provide robust justification of the effectiveness of telerehabilitation by the implementation of a randomized controlled trial blindly assigning COPD patients to: i) a home care and telerehabilitation group remotely monitored by a specialised private health care centre (Filoktitis - group A) or ii) a hospital-based rehabilitation group managed at a regular base through weekly visits by personnel at a state University rehabilitation centre (group B). iii) A third group that receives usual care (group C: control group; i.e.: neither home monitoring nor hospital based rehabilitation) is also included.

Investigators wish to identify a relationship between substantial changes in carbon dioxide partial-pressure (pCO2), which frequently occur during the transitions from rest to exercise (ΔpCO2 >4 millimeters of mercury [mmHg] from baseline), and the prevalence of cognitive dysfunction in COPD. In particular, it is anticipated to investigate the vascular effect of pCO2 oscillations in the regulation of cerebral blood flow (CBF) during exercise and its impact on cognitive function in Chronic Obstructive Pulmonary Disease (COPD). Furthermore, this study aims to examine whether major pCO2 oscillations have prognostic value in cognitive deterioration at 6, 12, and 18-month follow-up. In addition, the acute effect of 3-week pulmonary rehabilitation (PR) on cognitive function will be explored. The evaluation of cognitive function will be performed by the use of Standardized Mini Mental State Examination (SMMSE), Addenbrooke's Cognitive Examination (ACE-R), Montreal Cognitive Assessment (MoCA), and Telephone Interview for Cognitive Status (TICS) assessing several cognitive domains (cognitive scores) whereas Stroop test [color reading interference] will be used for measuring cognitive performance (Reaction-Time).

The aim of this study is to determine whether common CYP1A2 gene polymorphisms effect metabolism of theophylline in Han and Uygur Patients with chronic obstructive pulmonary disease patients.

In patients with Chronic Obstructive Pulmonary Disease (COPD) lifestyles with lower physical activity levels have been shown to increase the risk of hospital admissions and shorten survival rates. An established process in increasing activity levels is to undergo pulmonary rehabilitation classes. The investigators wish to identify whether the use of activity monitors,which will provide feedback on activity levels, will increase the physical activity levels of patients with COPD outside of the supervised pulmonary rehabilitation sessions.

Patients with Chronic Obstructive Pulmonary Disease (COPD) experience physiological and psychological complications, such as shortness of breath, anxiety and depression. This has negative influence on their social life, daily activity level and overall quality of life. Patients can participate in a pulmonary rehabilitation program (PR) for the purpose of better managing of the disease and its symptoms and for avoiding future relapses and hospitalisations. However there is a large number of dropouts from PR, and therefore a need for investigation of new activities. Singing training may be one such potential relevant and motivating rehabilitation activity. This study aims to investigate the effects of singing training on both physiological and psychological aspects, and will compare the effects with that of physical training (golden standard in PR). Effects will be investigated in a randomised controlled trial (RCT) with 10 week intervention period. In all the study includes 11 municipalities from around all regions of Denmark, and in all 220 participants.

This protocol describes a randomised controlled trial to test the hypothesis that 6 months of treatment with tiotropium and olodaterol will result in a reduction in bacterial load, an improvement in neutrophilic inflammation and clinical benefits compared with treatment with inhaled fluticasone furoate and vilanterol in patients with neutrophilic Chronic obstructive pulmonary disease (COPD). COPD is the third leading cause of death worldwide and a major cause of morbidity in the UK. Exacerbations drive disease progression and worsening quality of life and therefore prevention of exacerbations has been a major goal of treatment. In recent years, attempts have been made to phenotype COPD patients in order to target therapies to the correct groups of patients that will benefit. Inhaled corticosteroids (ICS) are primarily effective for patients with eosinophilic inflammation, while there are few established therapies for patients with neutrophilic disease. In recent years, all ICS preparations have been associated with a significant increased risk of pneumonia and this risk appears to be greatest in patients with non-eosinophilic inflammation. Combined treatment with long acting beta-agonists (LABA) and long acting muscarinic antagonists (LAMA) combinations appears to be a safer and more effective alternative for patients with non-eosinophilic disease. The combination of tiotropium and olodaterol in particular, has strong preclinical data supporting beneficial effects on neutrophilic inflammation. The trial is a multi-centre randomised open label controlled parallel group study with two treatment arms in 80 participants. Moderate to very severe COPD patients and currently treated with inhaled corticosteroid therapy will be randomised to treatment with either the combination of tiotropium and olodaterol (LABA/LAMA) or fluticasone furoate and vilanterol (ICS/LABA). Participants will return at 1 month, 2 months, 3 months and 6 months for sampling of the lower airway by sputum samples and the upper airway using oropharyngeal and nasopharyngeal swabs. Sputum will be used to test for airway neutrophilic inflammation. This study will make an important contribution to understanding "phenotyping" in COPD by identifying whether the combination of tiotropium and olodaterol improves airway bacterial load and restores neutrophil function in patients with neutrophilic COPD.

Health literacy refers to personal and relational factors affecting a person's ability to acquire, understand and use information about health and health services. In a need assessment study it was found that, the health services need to focus on health literacy factors in the follow up of patients with chronic obstructive pulmonary disease (COPD). Thus, this project evaluate the effect a of a health literacy partnership health promotion intervention (hospital, municipalities, university) after discharge from hospital with the use of motivational interviewing and tailored follow-ups on re-admission, health literacy, self-management quality of life and cost in people with COPD compared with usual care.

Brain oxygenation is determined by the product of CaO2 and the cerebral blood flow (CBF), the modification of one or the other can affect the neuronal O2 availability. Besides the effect of the PaO2, the CBF is also regulated by the PaCO2. During effort in state of hypoxia, the drop of the PaO2 associated to a potential decrease of the PaCO2 and therefore of the CBF, can create an important dizziness between the demand and the supply of cerebral O2. It seems that hypoxia can trouble in a significant way the response of central neurons, just as the production of a motor cortex generated motor command. Studies suggest that exercise in severe hypoxia condition can constitute a necessary threat for brain oxygenation and the motor command, with the consequence a decrease of the exercise performance. This projects aim to study effects of hypoxia on the brain function for patients suffering from chronic respiratory disease. Neurophysiologic responses of the brain while resting or exercising, including drip and cerebral oxygenation, cortical excitation and motor command resulting for hypoxic subjects before and after a treatment to correct abnormalities of gaz in blood. The study will use a multidisciplinary and supplementary methodological approach : the near-infrared spectroscopy (NIRS) to appreciate the drip and cerebral oxygenation, CBF, neurostimulation procedures and electromyography (EMG) to appreciate the cortical excitability, measure the level of central activation and motor command. The goals of this study will be : Measure the drip and cerebral oxygenation, the cortical excitability, mechanisms of voluntary activation and central fatigue to the effort for the chronic hypoxemic patient compared to healthy control subjects. Analyse disruptions of locomotion parameters and posturographyc, in simple and double task, involving different levels of cerebral task. Analyse acute effects of an improvement of arterial oxygenation for patients suffering from chronic obstructive pulmonary disease (COPD) on drip and cerebral oxygenation, cortical excitability, mechanisms of voluntary activation and central fatigue. Evaluate effects of a treatment by continuous positive airway pressure (CPAP) for patients suffering from obstructive sleep apnea (OSA) with the same parameters.
