Filter by:This study plans to learn more about pulmonary complications of human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS). Even though antiretroviral therapy (ART) has dramatically decreased the number of opportunistic infections and deaths in HIV infected patients, pulmonary complications (including chronic obstructive pulmonary disease (COPD) development and pneumonias resulting in decreased lung function) of HIV/AIDS continue to be a major cause of morbidity and mortality in this population. The mechanisms underlying the increased risk of COPD and decreased lung function in HIV infected individuals is not well understand and needs to be studied. The investigators hypothesize that the immunoregulatory consequences and immunosuppressive lung milieu secondary to HIV and cigarette smoke combine to increase the risk of lung infection and injury in HIV infected smokers, hastening the development of COPD. The mechanisms will be directly tested using blood and bronchial alveolar lavage (BAL) cells from smokers and nonsmokers with and without HIV infection.
The purpose of this study is to evaluate safety of Targeted Lung Denervation (or TLD) in patients suffering from moderate to severe COPD. It is hypothesized that TLD will have a similar safety profile and improved physiological and functional outcomes to a sham-control.
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.
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.
