Filter by:The study will investigate the effects of different training types ,including combined inspiratory with expiratory pressure threshold training,inspiratory pressure threshold training on patients with chronic obstructive airway disease and investigate whether expiratory pressure threshold training associated with inspiratory pressure threshold training would be better than inspiratory pressure threshold training alone, with regard to exercise capacity, respiratory muscle strength and endurance.
Some patients with a long history of AF develops PH "reactive" type with an increase in pulmonary vascular resistance due to vasoconstriction or structural changes of the vascular wall. RFA PVI + RFA GP is the "gold standard" in the treatment of patients with persistent AF, do not respond to optimal therapy. The rear area of the pulmonary artery bifurcation is adjacent to the roof and part of the front of the left atrium. In the projection of this area are ganglionic plexus of the left atrium, the sympathetic nerve fibers of the pulmonary artery and baroreceptors main pulmonary artery.Recent studies have shown that radiofrequency denervation of the pulmonary artery improves the quality of life in patients with PH.
The aim of this study is to compare the effectiveness of two treatments for severe / very severe COPD patients: one, conventional medicine based on 2013 Global Initiative for Chronic Obstructive Lung Disease (GOLD) and Chinese Treatment Guidelines; the other, TCM treatments and conventional medicine, which have been evaluated and have certain effect.
Chronic obstructive pulmonary disease has become a serious global health care and public health problems due to its high prevalence, high morbidity and heavy economic burden. Acute exacerbation of chronic obstructive pulmonary disease is one of the most important causes of death in patients with COPD. Systemic corticosteroids therapy is recommended in COPD exacerbations. In clinical practice for the treatment of acute exacerbation of COPD， antibiotic application is still controversial. Evidence from current guideline is based on strict criteria from randomized controlled trials, thus the given condition is simplified. Patients meet the criteria account for the minority in the real world. Therefore, it is still not clear whether most patients benefit from the recommended treatment. In our design, hospitalized patients with acute exacerbation of COPD will be enrolled, with their treatment, arterial hypoxemia, recovery time and length of hospitalization being observed. The main purpose is to evaluate the benefit effect of current recommended treatment of acute exacerbation of COPD in the real world.
The stroke volume variation (SVV), measured using the Vigileo-FloTrac system (Edwards Lifescience, Irvine, CA), has been shown to able to predict fluid responsiveness during one-lung ventilation (OLV) in patients undergoing pulmonary lobectomy (sensitivity: 82.4%, specificity: 92.3%).1 Many parameters such as tidal volume (TV),1-2 positive end-expiratory pressure (PEEP),3 respiratory rate (RR), 4 chest and lung compliance,5 heart rate and rhythm, and ventricular function and afterload,6-7 all have been documented to have effects on the SVV. SVV is calculated as the variation of beat-to-beat SV from the mean value during the most recent 20 seconds of data: SVV = (SVmax − SVmin)/SVmean, where SVmax, SVmin, and SVmean are, respectively, the maximum, minimum, and mean SV determined by the system. SVV may not be sufficiently sensitive to predict fluid responsiveness in patients with right ventricular (RV) dysfunction due to concomitant increases in RV afterload, that lead to a decrease in preload variation and subsequent inaccuracy in SVV measurements.8 OLV may increase airway pressure, resulting in increases in the RV afterload, end-diastolic volume, and stroke work index, thus impeding RV function.9-11The increases in the right ventricular afterload may exaggerate the cyclic variation in stroke volume.12 In the authors' previous study,9 they found that the high-frequency positive-pressure ventilation (HFPPV) was superior to continuous positive-airway pressure (CPAP) for OLV, resulting in significantly higher RV ejection fraction, lower RV afterload and higher arterial oxygenation, whereas the former limiting the adequate operative field visualization during video-assisted thoracoscopic surgery (VATS).13 The effects of the nondependent lung ventilation with HFPPV and CPAP on the SVV and fluid responsiveness during OLV has not yet been studied.
Background: Several clinical studies show high rates of anxiety and depressive disorders in Chronic Obstructive Pulmonary Disease (COPD), that suggest common underlying pathogenetic mechanisms of COPD and depressive disorders. The aim of this study is to evaluate the effects of aerobic exercise, proposed in the context of pulmonary rehabilitation, in a sample of COPD depressed patients without psychopharmacological treatment, through the correlation of some psychopathological variables and physical/pneumological parameters. Methods: The investigators have designed an observational longitudinal trial. The trial will be prospective 6-weeks randomized clinical study to evaluate the impact of aerobic exercise on depressive symptoms in 154 patient affected by COPD and depression, assessed by Hamilton Depression Rating Scale (HDRS). The investigators will also monitor anxiety, quality of life and neurocognitive function. Outcome measures: The investigators compare the variation of HDRS total score, as primary outcome measure, in two groups (A, B) of COPD depressed patients matched for: COPD status; depressive status; age; gender. Only the participants randomized in study group A will receive a 6-weeks aerobic exercise intervention. Statistical analysis: All tests are two-tailed and a p value 0.05 was considered significant. The difference between the two groups will be evaluated with Student's T test for normally distributed data, and with Mann-Whitney's U test, for those with not normal distribution. The normality of distribution will be evaluated with the Kolmogorov-Smirnov test. Any correlations among the variables under evaluation will be assessed by Spearman r correlation. Variables will be compared using the Chi-squared test or Fisher exact test for categorical variables. Discussion: There is a strong correlation between physical activity and mental health. Several data have suggested that aerobic exercise shows significant effects, comparable to pharmacotherapy and to psychotherapy, on reducing depressive symptomatology. The goal of our study is to propose an effective intervention to reduce the risk of severe depression in this special population, evaluating the variation of HDRS total score after the aerobic exercise intervention.
A prospective, randomized, patient-blinded comparison of the safety and efficacy of conscious sedation by propofol/alfentanil with propofol/ketamine in patients undergoing flexible fiberoptic bronchoscopy.
This study is designed to assess the effect of QVA149 (110/50 ug q.d.) versus placebo on pulmonary function and average physical activity levels in patients with moderate to severe Chronic Obstructive Pulmonary Disease (COPD).
The aim of this study is to compare the effectiveness and economic evaluation of three treatments for Chronic Obstructive Pulmonary Disease (COPD) patients: one, conventional medicine based on 2011 Global Initiative for Chronic Obstructive Lung Disease (GOLD) and Chinese Treatment Guidelines; another, TCM treatments, which have been evaluated and have certain effect; and finally, combination of both conventional medicine and TCM treatment, then determine which treatment is the most suitable for COPD patients.
1. To evaluate the health status of patients with Interstitial Lung Disease (ILD), and how this varies between subgroups of ILD. 2. To investigate the prevalence of symptoms, anxiety, depression, and sleep-disordered breathing within ILD patient population. 3. To assess the economic impact of ILD. 4. To understand how self-aware ILD patients are regarding their treatment/management. 5. To compare the demographic details, including smoking status and occupational history, of patients with interstitial lung disease
