There are about 28871 clinical studies being (or have been) conducted in Canada. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
This study will be a pragmatic, prospective, single-centre, unit-based cluster crossover, open-label registry trial. The cardiac surgical intensive care unit (CSICU) will be cluster assigned to alternating MAP targets in 6-month blocks in a sequence. Additional sites across Alberta may be added, as necessary.
Thoracic aneurysm incidence is estimated to 4.5 cases per 100 000. The manifestation as well as natural history of thoracic aneurysm depend on many factors such as its localisation, its diameter, presence of collagen disease and family history. For the ascendant aortic aneurysm, it is often linked to a degeneration of the media arterial layer of the arterial wall. The media degeneration is cause by the degeneration of the elastic fibres, which lead to a weakening of the arterial wall accompanied with dilation. This process is often due to age and is accelerated by high blood pressure. Amongst the numerous factors causing the aneurysm, the investigators find: hypertension, aortic bicuspid valve, smoking, atherosclerosis, trauma and genetic predisposition. The average growth rate of thoracic aneurysm is 0.1-0.2 cm/year. The risk of rupture is associated to the size of the aneurysm as well as patient's symptoms. The ruptures and dissections rates are accounted for 2-3/year for thoracic aneurysm between 5.5-6.0 cm in diameter. The patients are often limited in their daily life activities considering their concern and risk of rupture and/or dissect. The effects of exercise on the progression of the aneurysm dilation in patients with thoracic ascendant aortic aneurysm are unknown. It is well known that high blood pressure is a risk factor for rupture of the aortic aneurysm. Many studies have demonstrated the benefits of physical exercise regarding the lowering impact of blood pressure in a cardiac hypertensive population. At 3 and 6 months of the intervention, the subjects in the exercise group will have: 1) a lowered blood pressure at rest and during exercise, 2) maintenance/ improvement of muscle strength, 3) improvement of aerobic exercise capacity (VO2max), and 4) aortic dilation that remained stable or comparable to the control group. The research objective is to measure and compare to a control group, the effects of an exercise program on the following parameters: blood pressure response at rest and during exercise, as well as the VO2max at 3 and 6 months time of the intervention. This randomised and prospective study will take place at the " Institut Universitaire de Cardiologie et de Pneumologie du Québec (IUCPQ) " and will include patients who have a non-surgical ascendant thoracic aortic aneurysm (ATAA). The selected subjects will be randomised into two groups: 1) exercise group (n=15), and 2) control group (n=15). Both groups will be met prior to the intervention (baseline) and at 3 and 6 months time of the intervention, and measures described below will be recorded.
A multi-center global registry to obtain post-market safety and efficacy data on Boston Scientific Ureteral and Urinary Diversion Stents
cvMOBIUS is a North American registry of patients with ASCVD aimed at understanding patterns of care in ASCVD while evaluating the real world effectiveness of PCSK9 inhibitors.
A biomarker is a measurable indicator of the severity or presence of some disease state. In this study, brain metastases patients who will be receiving radiation treatment, will undergo CT (Computed Tomography) and MRI (Magnetic Resonance Imaging) scans prior to and after radiation treatment to measure these biomarkers. This is a single-center phase II study to validate the predictive abilities of biomarkers, in terms of determining how patients will respond to radiation treatment.
The purpose of this research study is to determine if 5 (five) fractions of external radiotherapy with higher radiation doses per fraction to the pelvis leads to similar results to the standard of care external radiotherapy treatment that is comprised of 25 fractions of external radiotherapy with lower radiation doses per fraction to the pelvis. This study aims to investigate the impact in quality of life associated with hypofractionated Whole Pelvis Radiotherapy (WPRT) in comparison to conventionally-fractionated WPRT in patients with unfavorable-intermediate and high-risk prostate cancers. This information is valuable as hypofractionated WPRT is a more attractive and convenient treatment approach, and may become the new standard of care if proven to be well-tolerated and effective. Therefore, this study aims to provide a more rational justification for use of hypofractionated WPRT in future larger randomized trials by comparing this strategy with the current standard of care. This study will also provide an initial understanding of the toxicity profile and cancer control associated with hypofractionated WPRT and High Dose Rate Brachytherapy (HDR-BT).
The objective of the study is to evaluate and compare the performance of somofilcon A to etafilcon A when worn on a daily disposable wear modality over a period of approximately one week.
The primary objective of this study is to compare belzutifan to everolimus with respect to progression-free survival (PFS) per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) as assessed by Blinded Independent Central Review (BICR) and to compare everolimus with respect to overall survival (OS). The hypothesis is that belzutifan is superior to everolimus with respect to PFS and OS.
This is a study for adults (18-75 years) who have successfully completed treatment either with Dupilumab or with Upadacitinib in the study M16-046. At the end of M16-046, they have the option to receive Upadacitinib with a duration of 52 weeks beyond the timeframe of Study M16-046. There will be a 30 day follow-up visit after the treatment period is completed. Main objective of this study is to assess long-term safety, tolerability and efficacy of upadacitinib in participants with moderate to severe atopic dermatitis who successfully completed treatment in the study M16-046.
The present study will investigate the effects of Nic's Ketogenic diet, comprised of 70% fat, 5% carbohydrate, and 25% protein on middle-aged males and females with mid-range elevated LDL. With the mixed evidence on the causative effect of LDL cholesterol on increased cardiovascular health risk, further studies are warranted to examine the relation of elevated LDL and other biomarkers of cardiovascular health in response to a lifestyle intervention. Furthermore, this study will investigate weight loss and body composition changes with adherence to this dietary intervention over a 140-day period. In this study the efficacy of Nic's Ketogenic diet on weight loss and biomarkers of cardiovascular health will be examined.
