Filter by:Chronic obstructive pulmonary disease (COPD) is a common disease , and characterized by progressive development of airflow limitation. Small airway disease (obstructive bronchitis) and lung parenchyma damage (emphysema) are the main mechanisms of chronic airflow limitation. Research shows that small airway resistance increased by 4-40 times in COPD patients, and become the main part of the airflow obstruction. Impulse oscillation system (IOS) is able to measure the total airway resistance, the central airway resistance and the peripheral airway resistance, which is now widely used to assess small airway function in COPD patients. While High resolution CT (HRCT) is easy to operate and its images are intuitive. Meanwhile it can measure the proportion of emphysema, the airway diameter and the thickness of airway wall. Both of these two tests have great significance in small airway evaluation. Chronic obstructive pulmonary disease with acute exacerbation (AECOPD) is an acute onset process, which is characterized by the aggravation of respiratory symptoms and deterioration of pulmonary function. However, the structural and functional changes of small airway in AECOPD are not clear. Inhalation drugs are the main treatment for stable COPD , and inhaled corticosteroid（ICS）+long-acting beta2-agonist（LABA） are used to treat patients with severe and severe airflow limitation. The particles in traditional inhalation drugs are larger and mainly deposited in large airways, and their effects on small airway function are relatively small. The objectives of the investigators study are COPD patients. The study is divided into two parts, that is the part of AECOPD patients and the part of stable patients . Patients with AECOPD are arranged to take HRCT and IOS test to assess the small airway changes.Patients with stable COPD are randomized to take either beclomethasone / formoterol (particle diameter for 1.4-1.5um) or budesonide / formoterol (3.2um) for three months. The structure and function changes of small airway in different stage will be evaluated and the efficacy of these two drugs is to be compared. This study is expected to highlight the investigators understanding on the role of small airways in COPD, and provide a guideline to clinical standardized treatment as well as evaluation of patients' conditions.
This observation will look at patient care decisions of the primary healthcare provider utilizing the results of the DNA testing of patients' metabolic pathways using 2C19, 2C9, 2D6, 3A4, Factor II, Factor V and MTHFR and VKORC1. Findings of the data collection will be published to optimize the benefits of pharmacogenomics testing and publish health outcomes.
This research is aimed at verifying the effects of diets with high protein and low glycemic index (GI) on weight management among overweight or obese Chinese adult. Additionally, the investigators intend to verify the effects of two new approaches, including food replacement and Internet-of-things (IOT) monitoring on weight control.
Chronic sinusitis is a disease involving severe swelling of your facial sinuses and nasal cavity. Chronic sinusitis is a common disorder and roughly 5% of adult men and women have chronic sinusitis in Canada. Surgery has shown to have benefits for people suffering from chronic sinusitis. There are two surgeries which have been shown to help people: 1) Endoscopic sinus surgery with septoplasty and 2) Septoplasty alone. Both surgeries have research which show they help improve quality of life and reduce symptoms. However, it is unknown which surgery is better. 'Endoscopic sinus surgery with Septoplasty' uses special telescopes through the nostrils to make the nasal septum straight and open the facial sinuses without any incisions. The sinuses are opened using special microscopic instruments and the procedure takes approximately 90-120 minutes. 'Septoplasty alone' is a shorter (take approximately 25-30 minutes) and less invasive (do not open the facial sinuses) that might provide the same benefits compared to the larger and longer endoscopic sinus surgery. Currently, performing 'Endoscopic Sinus Surgery and Septoplasty' together is the standard of care, however, there is limited evidence to support just performing 'Septoplasty alone' provides similar results but it is shorter and has lower risks. This represents a significant gap in the investigators' knowledge, which adversely impacts a doctor's ability to counsel patients who have chronic sinusitis and elect to undergo surgery. The purpose of this study is to understand which surgery (endoscopic sinus surgery plus septoplasty OR septoplasty alone) is the most appropriate for people with chronic sinusitis. You are being asked to participate in this study because you have chronic sinusitis and are also going to have surgery to improve your quality of life.
This study aims to analyze the impact of a brief psychological support intervention in the promotion of the adherence to Non Invasive Ventilation (NIV) among people with Chronic Obstructive Pulmonary Disease (COPD). The investigators expect to see a positive impact of this intervention on both physical and psychological well-being, and consequently, a reduction of health costs.
The study is a epidemiological, cross-sectional study in a mainly rural area of Denmark in Denmark. Life expectancy is shorter, morbidity is higher, and social problems more prevalent than in the urban areas of the country. The population study aims at examining complexities of environmental, hereditary, lifestyle, and social factors as determinants and predisposing factors for morbidity, health, and quality of life. The study will cover physical, mental, and social dimensions and examine family patterns and subgroups. The study will provide baseline information for later follow-up.
The aim of this long-term observational study is the documentation of the use of PASCORBIN® 7.5 g in patients with vitamin C deficiency. Regarding the vitamin C deficiency, the investigators focus on the acquisition of data of the underlying diseases and the reduction of symptoms, that are related to oxidative stress and vitamin-C-deficiency. Next to this, exact assessment of medical tolerance and details of treatment requirements are further aims. Here the investigators take into account acute and chronic underlying medical conditions. Further health economic data are collected.
Disordered iron metabolism characterizes an important determinant of impaired exercise tolerance and work capacity. Iron-deficiency anemia commonly features impaired aerobic capacity caused by decreased oxygen carrying capacity, and has been associated with a negative effect on dyspnea and walking distance. Apart from that, iron deficiency without anemia was shown to affect endurance and energetic efficiency via decreased tissue oxidative capacity. Consequently, depleted iron stores could be capable of causing fatigue, breathlessness and impaired exercise tolerance, which are common features of chronic cardiopulmonary diseases like chronic heart failure (CHF) and COPD (Chronic Obstructive Pulmonary Disease). Indeed, a current surge of interest aimed at potential underlying determinants in CHF and COPD independent of the primarily disordered organ. Recent studies identified iron deficiency without anemia as an independent factor of reduced exercise intolerance in CHF as well as in COPD. Moreover, intravenous iron application significantly improved exercise capacity in CHF patients with iron deficiency in presence as well as in absence of anemia. Comparable to CHF, the daily living of patients with COPD is compromised by impaired exercise tolerance. However, airflow limitation, as the foremost characteristic of COPD shows only weak associations with exercise capacity. In line with that, exercise capacity showed no remarkable improvement in lung transplant recipients, underlining the presence of systemic determinants of limited exercise tolerance like iron deficiency. The investigators showed that iron deficiency is present in 50% of stable COPD patients (unpublished data), which is according to recently published data. The investigators presume that iron deficiency contributes to limited exercise capacity in COPD patients. Thus, the aim of this study is to determine whether iv iron is associated with increases exercise capacity in COPD. Therefore the investigators hypothesize that filling up depleted iron storages will increase exercise capacity, measured by the 6-MWT (Minute Walking Test).
To analyse and describe sinus microbiota, during hard to treat (or refractory) rhinosinusitis, using culturomic and metagenomic methods (i.e. to culture on many different medium of culture to grow hard to cultivate bacteria + to sequence and analyse all DNA contained in samples). Samples are middle meatus swabs or pus aspiration, done during usually patient following.
The ACCELERATION (ACtivity, smoking Cessation, healthy Eating and aLcohol Education, inteRvention, and motivATION) Program is a collaborative project in cancer and chronic disease prevention that has been designed by and will be delivered amongst cardiopulmonary rehabilitation and prevention programs and cancer centres in Ontario (ON), British Columbia (BC), Quebec (QC) and Nova Scotia (NS). This project is being funded by the Canadian Partnership Against Cancer, Health Canada and Heart and Stroke Foundation of Canada and in the amount of $2.4M over a 3 year period (October 2013 - September 2016). The ACCELERATION Program is a 12 week structured model of behavioural interventions and education around self-management and prevention that aims to access readily available and referable people for primary prevention intervention.This program aligns with current provincial, national and international chronic disease prevention and management strategies. The goal of the ACCELERATION program is to measurably and effectively change the risk factors and health behaviours known to impact cancer and other chronic diseases. Specifically we will aim to increase physical activity, reduce smoking, encourage healthy eating, and moderate alcohol consumption in about 3,000 participants across Canada over 3 years.
