Filter by:The purpose of this study is to assess the safety and tolerability of single doses of LAS190792 administered by inhalation to patients with mild persistent asthma and moderate to severe chronic obstructive pulmonary disease (COPD) and also to assess the ability of LAS190792 to produce bronchodilation (opening of the airways).
This study will assess Specialized Community Disease Management (SCDM), an intervention which employs various evidence-based strategies to engage substance using co-morbid patients while in the hospital and follow them into the community via an empirically validated telephone approach as well as contact with a trained community health worker peer specialist. The investigators will first adapt and refine the core SCDM intervention with patient, provider, and stakeholder input through an active community advisory board. The investigators will then conduct a three-year, randomized controlled trial of 222 patients enrolled prior to hospital discharge who are diagnosed with congestive heart failure, pneumonia, acute myocardial infarction, chronic obstructive pulmonary disease, diabetes mellitus, or end-stage renal disease, and a substance use disorder (SUD). Patients will be randomized to either the SCDM intervention or Treatment as Usual (TAU), in which a team of nurse navigators and community health workers follow patients (primarily by telephone) for 90 days post-discharge, but do not address the specific needs of SUDs. The investigators will test the following four hypotheses: (1) patients randomized to SCDM will demonstrate larger reductions in substance use measured by urine-confirmed self-reported days using over the 6-month follow-up compared to patients randomized to TAU, (2) patients randomized to SCDM will attend more specialty substance abuse intervention and treatment sessions over the 6 month follow-up than patients randomized to TAU, (3) patients randomized to SCDM will demonstrate reduced HIV transmission risk behaviors and greater rates of HIV testing over the 6 month follow-up than patients randomized to TAU, and (4) patients randomized to SCDM will experience fewer days of rehospitalization and use of acute emergency services than patients randomized to TAU.
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 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 this study is observe clinical practice including glucocorticoids treatment in AECOPD in China.
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.
