Filter by:In HIV+ cigarette smokers, with no prior history of pulmonary infections, emphysema is often developed at an earlier age and is a significant cause of morbidity despite treatment with antiretroviral drugs. Preliminary data gathered from HIV+ individuals that smoke cigarettes strongly support the hypothesis that the combination of HIV infection and smoking creates increased stress in the lower respiratory tract. To examine the underlying factors that contribute to the accelerated development of emphysema in this cohort, samples from the lower respiratory tract will be provided by HIV+ and HIV- subjects. The samples collected will serve as biomarkers for assessing the onset of emphysema.
In the literature, the effects of acute oxygen administration on exercise tolerance and related symptoms have often appeared to be contradictory. Some investigations have reported benefits from acute oxygen supply during exertion, including increased exercise performance, reduced dyspnea, and better cardiorespiratory adaptations, whereas other studies have reported no improvement. Recently, we advanced then the hypothesis that some patients would be non-responders and even worsen under oxygen treatment. The preliminary results confirmed our hypothesis since we demonstrated that while 56% of the patients were improved with supplemental oxygen, 16% were non-responders and 28% were negative-responders (decreased performance and increased dyspnea during endurance exercise with supplemental oxygen). However, this was a pilot study offering preliminary insights and tentative conclusions that must be confirmed in a larger case series. The aims of this retrospective study was : 1. To confirm on cohorte and with clinical test (the 6-minute walking test - 6WT) the deleterious responses to acute oxygen supplementation in LTOT (long terme oxygenotherapy treatment) and non-LTOT patients who exhibit exercise desaturation. 2. To identify the predictive factors among the clinical data (i.e., anthropometric, spirometric and gazometric data) and/or functional data recorded during rehabilitation program
To demonstrate the free combination of budesonide and indacaterol is as efficacious as fluticasone and salmeterol in patients with COPD
The purpose of the present project is to investigate the physiological effects of two different types of exercise training in COPD patients. The patients will be examined before, during and after 8 weeks of training to evaluate the effect of different types of skeletal muscle stimulation on health related quality of life, 6 min walking distance, flow mediated dilation, and histological properties of skeletal muscle cells, regarding oxidative capacity, fiber type, purinergic receptor amounts and measures of systemic inflammation. The study will test the hypothesis that: Resistance training is superior to endurance training in patients with COPD
The effect of pulmonary rehabilitation in patients with chronic obstructive pulmonary disease (COPD) has been based on systemic outcome measures, however, little is known about the effectiveness of this intervention on patients' lung function. The forced expiratory volume in one second (FEV1), despite of being the gold standard for assessing lung function in COPD, is poorly responsive to pulmonary rehabilitation. Thus, an objective and responsive outcome measure to assess the effect of pulmonary rehabilitation on lung function is needed. Computerized respiratory sounds have been found to be a more sensitive indicator, detecting and characterizing the severity of respiratory diseases before any other measure, however its potential to detect changes after pulmonary rehabilitation has never been explored. Therefore, this study aims to assess the effects of pulmonary rehabilitation on the characteristics of computerized respiratory sounds in patients with COPD. A randomized controlled study with one group undergoing pulmonary rehabilitation (n=25) and other group receiving standard care (n=25) will be conducted. The pulmonary rehabilitation program will included exercise training (3*week) and psychoeducation (1*week). Computerized respiratory sounds, lung function, exercise capacity, quadriceps muscle strength, health-related quality of life and health services use will be assessed in both groups, at baseline, immediately post-intervention and at follow-ups (3 and 6 months after PR). Descriptive and inferential statistics will be used. It is expected that significant changes occur on the characteristics of computerized respiratory sounds in patients enrolled in the pulmonary rehabilitation group, in comparison with patients receiving standard care. Thus, computerized respiratory sounds could provide a simple, objective and non-invasive measure to assess lung function changes after pulmonary rehabilitation.
Background: Optimizing the basic palliative care has been shown beneficial to patients in end-of-life care, the general practitioner (GP) having a pivotal role in the health care system, providing comprehensive and continued medical care. The aim of the study is to investigate the effect of a complex intervention in general practice on GPs' awareness of and confidence in providing end-of-life care. Method: A follow-up study among 404 general practices in Central Denmark Region. The participating general practices will get the opportunity to receive education in palliative care and access to an electronic support, which provides advice on palliative care and an overview of the palliative population in each medical practice. The education and the support will focus on patients suffering from either metastatic cancer or chronic obstructive pulmonary disease (GOLD stage 4). The end-of-life care delivered by the GPs to their deceased patients will be analysed, based on questionnaires to GPs and register data related to the deceased patients before and after the intervention, . Primary outcomes: Place of death of deceased patients, time spent at home, and number of hospital admissions in the last three months of the patients' lives. Secondary outcomes: Number and kinds of contacts between GPs and patients, use of relevant medicine and of the 'Safety Box'. Finally GPs' confidence concerning palliative care will be assessed in questionnaires.
Chronic Obstructive Pulmonary Disease (COPD) is a progressive disease that is characterized by loss of lung function, leading to breathlessness, poor quality of life, loss in productivity, and increased mortality. The World Health Organization estimates that COPD will be the third leading cause of death worldwide by 2020, accounting for more than 7 million deaths annually. COPD patients frequently experience 'lung attacks', during which breathlessness, coughing, and sputum production dramatically increase, leading to urgent office visits, emergency admissions and hospitalizations. Lung attacks reduce patient quality of life and cost the Canadian health care system nearly $4 billion dollars each year in direct and indirect costs. Lung attacks can be effectively managed if they are identified and treated early, but symptoms of a lung attack often overlap with those of other common conditions such as heart failure, pneumonia and even influenza. Because there are no tests that can separate lung attacks from these conditions, doctors struggle to accurately diagnose lung attacks at an early stage when drugs are most effective. This can lead to a delayed or even incorrect diagnosis and inappropriate treatment. This research will address this critical need. Our goal is to improve COPD patient care by developing new blood tests that will help identify patients who are in the early stages of a lung attack. Doctors will be able to use these tests to treat lung attacks at earlier stages than is currently possible. These blood tests will enable doctors to personalize management of COPD to meet the needs of the individual patient. Hypothesis: New biomarker blood tests can be used to better identify and manage patients with COPD.
The purpose of this study is to explore the impact of Family-based pulmonary rehabilitation (PR) on patients with chronic obstructive pulmonary disease (COPD) and their family members. Dyads (patient and respective family member) will be randomly allocated to either a Family-based PR group or a Conventional PR group. PR programs will consist of exercise training and psychoeducation. In the Family-based PR program, both patients and family members will participate in psychoeducation sessions. In the Conventional PR group, only patients will be included. In both groups, exercise training sessions will be exclusively for patients. It is expected that, by including patients with COPD and their family members in Family-based PR, they will become more competent and confident in the management of the disease, thus reducing the overall impact of COPD on patients and family members' well-being.
Haemoptysis is the coughing up of blood originating from the respiratory tract. It is a common and worrying clinical symptom which can be due to different aetiologies including lung cancer, tuberculosis, COPD, bronchiectasis, pneumonia, acute bronchitis or unknown origin (cryptogenic haemoptysis). Epidemiology and optimal diagnostic approach are largely unclear. Aims of this study are to define current epidemiology and to provide the best diagnostic approach by providing a diagnostic algorithm.
The purpose of the study is to determine the efficacy of mindfulness-based cognitive therapy (MBCT) as an add-on to pulmonary rehabilitation (treatment as usual, TAU) in chronic obstructive pulmonary disease (COPD). The investigators hypothesize that compared to treatment-as-usual, the add-on of MBCT will result in improved psychological (anxiety, depression) and physical outcomes (physical health status, activity level, inflammatory markers). Furthermore, the investigators will explore the possible moderating role of individual differences in sociodemographic and disease-related characteristics and the perceived quality of the therapeutic alliance, as well as the mediating role of mindfulness, breathlessness catastrophizing, self-efficacy, and self-compassion for the hypothesised effect.
