Filter by:A standardized diagnostic strategy of pulmonary embolism will be applied to eligible patients, incorporating a clinical probability score (revised Geneva score), plasma D-dimer assay and if necessary, a multidetector-row CT angiography thoracic and venous ultrasound of the lower limbs. All the patient with a pulmonary embolism diagnosed or not, will be followed for 3 months.
This is an early feasibility study to investigate whether transcutaneous electrical stimulation applied to the abdominal wall muscles synchronous with voluntary exhalation can be used to support ventilation and affect hyperinflation in patients with chronic obstructive pulmonary disease. As part of this study, the effect of a range of stimulation intensities and stimulation timing profiles will be explored.
Initiatives aimed at reducing Emergency Department (ED) wait times and improved community health initiatives are major priorities in Canada. Three of the most common chronic diseases worldwide are Diabetes Mellitus (DM), Congestive Heart Failure (CHF) and Chronic Obstructive Pulmonary Disease (COPD). These diseases are on the rise and currently cost the Canadian health care system billions of dollars every year including the cost of hospitalizations and ED visits. The existing health care system does not have the resources and manpower to effectively care for these patients in the future. Paramedics are currently employed to provide Emergency Medical Services in remote, rural and urban settings in Canada. They are highly trained health care practitioners that are mobile in the community and currently work in a physician medically delegated act model and therefore are positioned to take on new collaborative roles to deliver patient care in the community setting. Increased community paramedic care could decrease the utilization of the health care system resources for patients with chronic disease. Using a randomized control trial design we will attempt to answer the question of whether whether non-emergency community paramedics conducting home visits to undertake assessments and evidence-based treatments of patients in partnership with family doctors will decrease the rate of patient hospitalization.
The primary goal of this line of research is to see if realistic manipulative protocols can be developed to produce sustained reductions in residual volume and improve pulmonary function parameters in people with Chronic Obstructive Pulmonary Disease (COPD).
Chronic Obstructive Pulmonary Disease (COPD) is a leading and still increasing cause of disease and death worldwide, affecting those in both developed and developing countries. This imparts a massive burden of ill health, in turn imposing huge healthcare costs to society. For effective treatment of COPD (as opposed to providing short term relief) early disease must be targeted. The small airways of the lung (those less than 2mm) are the first affected in COPD, but current methods to assess their function are relatively insensitive. There is therefore a need for new, accurate methods for detection of small airway dysfunction with sensitivity to shortterm change and regional discrimination. In previous studies with hyperpolarised (HP) 3He MRI in smokers with normal pirometry and patients with early stage COPD, we showed sensitivity to early changes in lung ventilation and structure. The hyperpolarised gas MRI technique is safe. In particular, the lack of ionizing radiation permits patients to be imaged on multiple occasions. This and its inherent sensitivity to regional lung ventilation and function make it an ideal imaging tool for the assessment of novel lung therapies for diseases of the small airways. The purpose of this pilot study is to determine short and long term reproducibility of a comprehensive set of functional imaging data; using hyperpolarised gas MRI, conventional MRI and lung physiology measurements in patients with moderate to severe COPD. In addition,how sensitive the imaging techniques are to changes in lung function after treatment with a standard (bronchodilator) inhaler will also be assessed. This pilot study will serve as a platform for future larger scale studies, aimed at better understanding of and intervention in early COPD.
Macrolides are potent inhibitors of cytochrome P450 isoenzyme 3A4（CYP3A4）and thus interfere with the pharmacokinetics of many other drugs that are metabolised by this enzyme like theophylline.The aim of this study is to determine whether azithromycin can effect theophylline metabolism in patients.
This clinical trial is designed to determine whether an intervention that provides information to primary care providers about gaps in care for their patients recently discharged from hospital for COPD can reduce hospital re-admissions and mortality and improve their patients' quality-of-life.
Identify a biologic (molecular) basis for the increased susceptibility of cigarette smokers to pulmonary TB (Mtb) by testing the hypothesis that smoking reprograms AM polarization towards a distinct phenotype associated with impaired host defense function against Mtb and that normalization of that phenotype via therapeutic modulation of the Alveolar Macrophage (AM) polarization or smoking cessation can restore the anti-Mtb host defense function of AM.
Main adverse events of Roflumilast are weight loss, loss of appetite, insomnia, headache, diarrhea, vomiting, and nausea. Although the majority of these adverse reactions were mild or moderate. They occurred mainly at the beginning of therapy and mostly resolved with continued treatment around for two weeks according to experiences of clinicians. These adverse events occur more often in Roflumilast 500 μg than 250 μg, having negative impact on compliance of patients at the early stage of treatments. Thus, investigators aim to compare the drop-out rates between the usual dosage (Roflumilast 500 μg once daily) and the dose escalation (Roflumilast 250 μg once daily for 4 weeks and then escalating dose of 500 μg once daily).
