Filter by:Introduction. Nonspecific low back pain (NSLBP) is a very prevalent medical condition, especially in subjects with chronic obstructive pulmonary disease (COPD). The diaphragm is a respiratory muscle, but it takes part in trunk stabilization on lumbar spine. NSLBP is related to lack of spinal control. The COPD symptoms include lack of efficiency in diaphragm, which could be connected to NSLBP. Hypothesis and objectives. COPD can contribute to NSLBP. It is associated with diaphragm weakness, severity of respiratory function, lower level of physical activity and quality of life in COPD. Methods. A descriptive observational cross-sectional study was conducted with two groups: the first one with subjects with COPD and the second one with subjects without it. Data were collected on: pulmonary function; respiratory muscles strength; trunk postural control; quality of life with COPD; physical activity level; lumbar pain presence, intensity and disability. Data were collected in a single session.
Chronic Obstructive Pulmonary Disease (COPD) patients are more likely to develop acute hypercapnic respiratory failure. In the acute phase, non invasive ventilation has been shown to improve mortality and reduce intubation rate. Few studies are available about long term benefits of home non invasive ventilation in COPD patients with chronic hypercapnic respiratory failure who survived after an acute episode. The purpose of this study is to determine whether home non invasive ventilation can reduce recurrent acute hypercapnic respiratory failure in COPD patients who survived an acute hypercapnic respiratory failure episode treated by non invasive ventilation.
The goal of this study is to evaluate the overall impact of Telehomecare on COPD and HF patients and system level outcomes using a comparison group of patients that did not participate in the program (for up to 18 months). This evaluation study will explore costs, participants' experiences, perceptions, and patterns of use related to Telehomecare. The study will include eight Local Health Integration Networks (LHINs) across Ontario, Canada.
Anxiety and depression have negative effect on outcomes of chronic obstructive pulmonary disease (COPD). Intervention strategy including behavioral-cognitive therapy and pulmonary rehabilitation are promising in improving life quality, disease symptom and outcomes. But there's not standard algorithm in China so far. The study aims to compare the effectiveness of these interventions and develop an intervention algorithm of anxiety and depression in COPD.
Anxiety and depression are common comorbidities of chronic obstructive pulmonary disease (COPD). However, the exact prevalence is not known in China. COPD patients with anxiety and depression tend to have more severe symptoms and worse prognosis, but the related evidences are not strong enough. The study aim to investigate the prevalence and long-term outcome of anxiety and depression in COPD.
Pulmonary hypertension is a common complication of chronic obstructive pulmonary disease (COPD). It is reported that over half of COPD patients develop pulmonary hypertension. COPD and pulmonary hypertension may have pathological or genetics interactions so that patients having both disorders tend to have poor prognosis. Echocardiography is widely used to detect pulmonary hypertension, but it's not accurate enough. Therefore, high-quality data reflecting the prevalence, disease course and outcome of pulmonary hypertension in COPD is very limited in China. The aim of the study is to detect pulmonary hypertension with right heart catheterization, describe its outcome in Chinese COPD patients and explore the underlying interaction mechanism.
Chronic obstructive pulmonary disease (COPD) is closely related to venous thromboembolism (VTE). But it is difficult to identify VTE in COPD patients in clinical practice. Therefore, the prevalence data of PTE in COPD is limited. Pulmonary thromboembolism (PTE) is an important factor effecting patients outcomes, but existing researches only have short follow-up time less than 1 year. This study aim to develop an early detection system of PTE in COPD and explore the disease course and prognosis.
Over half of chronic obstructive pulmonary disease (COPD) patients develop pulmonary hypertension. The current therapy focuses only on the basic disease and there are a lot of controversies about the use of PAH target therapy in group 3 pulmonary hypertension. Our study is to explore whether sildenafil, a pulmonary arterial hypertension (PAH) target drug, could be efficient and safe in improving symptoms and survival of severe pulmonary hypertension caused by COPD.
The pulmonary vasculopathy and right heart dysfunction in COPD are drawing increasing attention these days. Recent researches show that pulmonary vasculopathy and right heart dysfunction relate to greater severity in COPD. Applying appropriate modalities for early detection of pulmonary vasculopathy and right heart dysfunction is of great importance. What's more, the interaction mechanism between pulmonary vasculature, right heart and COPD still needs to be further studied. The aim of our study is to develop an assessment system of pulmonary vasculopathy and right heart dysfunction in COPD patients and elucidate their impact on COPD course and outcome.
Chronic obstructive pulmonary diseases (COPD) coexisting with obstructive sleep apnea is called overlap syndrome (OS). Patients with OS seem to have worse prognosis than patients with only one disorder. Noninvasive positive pressure ventilation is an efficient treatment in obstructive sleep apnea, but the effectiveness in improving outcomes of OS patients is still not fully investigated. The aim of this non-randomized concurrent control trial is to evaluate noninvasive positive pressure ventilation's effectiveness in OS patients.
