Filter by:ECMO(Extracorporeal membrane oxygenation) is being essential for cardiopulmonary failure patients. There are two types of ECMO, which is veno-veno (V-V) that can be used in respiratory failure patients and veno-arterial (V-A) that can be used in cardiac failure patients. V-A ECMO can also be used during lung transplantation, substitution of cardiopulmonary bypass, which can show sufficient performance during operation and better postoperative outcome. However, regarding V-A ECMO circulating from femoral vein to femoral artery, there is a pro blem of differential hypoxia which might influence coronary artery and head vessels. In this prospective study, the investigators are planning to put another ECMO catheter into internal jugular vein which takes a role of left to right shunt, to mitigate the hypoxia of coronary artery.
The purpose of this study is to assess the effect of pulmonary rehabilitation on the transport of secretions, inflammation and respiratory resistance, and its repercussions on the quality of life in patients with bronchiectasis.
Bronchiectasis have multiple etiologies but share a similar bronchial injury associated with inflammation, which leads to a progressive lung deterioration. This disease is responsible for a frequent access to care with an exacerbation rate of 1.8 per year with a high risk of hospitalization. Natural history is marked by recurrent infectious diseases which are the main prognosis factor. This disease is associated with an inflammation rate in the lung as well as in the blood. Up to now, no study has been described comorbidities associated with this chronic disease but our hypothesis is that cardiovascular diseases will be more frequent in these patients. In fact systemic inflammation driven by bronchial infections may increase frequency of cardiovascular diseases. The investigators decide to conduct a monocentric observational study to define the prevalence and characterization of cardiovascular comorbidities as well as markers of accelerated aging. We would like to test the hypothesis that cardiovascular comorbidities are frequent in bronchiectasis and may be associated with markers of inflammation and aging. Phenotype of the lung disease will include: spirometry, plethysmography, DLCO measurement according to the ATS/ERS guideline. 6M walking test and echocardiography will be also performed. Frequency of comorbidities will be calculated with data from questionnaire as well as standardized explorations. Aging related manifestations will be measured: arterial stiffness using aortic pulse wave velocity, bone mineral density using dual energy X-ray absorptiometry. Appendicular skeletal muscle mass and grip test were also performed. Blood test were also performed to measure inflammatory markers, cytokines and length of telomere in circulating leucocytes.
The objective of this study is to assess the efficacy and safety of Salmeterol-Fluticasone （ICS and LABA）combined inhaled therapy for non-cystic fibrosis（non-CF）bronchiectasis patients with chronic airflow obstruction. Moreover, subgroup analysis is performed to explore which populations of bronchiectasis patients this treatment is suitable for.
A biomarker cohort study design is proposed to study whether specific airway microbiota alterations are associated with pulmonary Non-tuberculous mycobacteria (NTM) disease. In a cohort of 200 subjects suspected of having pulmonary NTM disease, the investigators will evaluate the airway microbiome using an aliquot of the induced sputum and upper airway samples. Since induced sputum may reflect different regions of the upper/lower airways, the investigators will evaluate the upper and lower airway microbiome in a subgroup (case-control group) of patients using samples obtained through upper airway sampling and bronchoscopy, respectively.
This is a multi-center, randomized, double-blind, parallel-group trial. After a 2-week run-in period, eligible patients will be, based on the randomization codes kept in sealed envelopes, randomly assigned to receive usual care (mucolytics and/or chest physiotherapy) plus oxygen inahaltion (1 hr daily for 12 consecutive months) or hydrogen inhalation (1 hr daily for 12 consecutive months) provided by the sponsor. At 3 months after the end-of-treatment, a follow-up visit will be scheduled for all patients.
The goal of this research is to optimize the MRI system to obtain ideal lung images using Hyperpolarized (HP) Noble and Inert Fluorinated Gases as contrast agents. Lung coils tuned to the frequencies of these gases will be used. This study will take place at TBRHSC in the Cardiorespiratory Department and in the Research MRI facility.
This study will investigate the short-and long-term effects of the home-based pulmonary rehabilitation on peripheral muscle strength, functional capacity and quality of life in patients with bronchiectasis. The participants will be randomized into two groups: control group (usual care and recommendations for practice exercise) and training group, that will perform aerobic (stepping training) and resistance training (lower and upper limbs) for eight weeks, three times a week. At baseline, immediately after finishing and after six months the patients will undergo assessments.
Bronchiectasis is a result of chronic inflammation compounded by an inability to clear mucoid secretions. Inflammation results in progressive destruction of the normal lung architecture, in particular the elastic fibers of bronchi. Currently there is no effective drug for bronchiectasis. This study intends to carry out an open, single-center, non-randomized, self control phase I/II clinical trial. During the treatment, bronchial basal cells (BCCs) will be isolated from patients' own bronchi by bronchoscopic brushing and expanded in vitro. Cultured cells will be injected directly into the lesion by fiberoptic bronchoscopy after lavage. After six-month observation, the investigators will evaluate the safety and effectiveness of the treatment by measuring the key indicator-- the CT imaging of dilated bronchi as well as four secondary indicators including the pulmonary function, laboratory factor level, incidence of acute exacerbation and the patients' self-evaluation.
The purpose of this study is to provide patients and their physicians with greater understanding of the risks and benefits of commonly used therapies for treatment of non-CF bronchiectasis
