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.
The objective of this study is to demonstrate the safety and efficacy of the Penumbra SMART COIL® System, including the WAVE™ Extra Soft Coils (WAVE) as a fill and finish coil, in the treatment of intracranial aneurysms. Imaging will be analyzed by an independent core lab to assess aneurysm occlusion rates and perform a comparative analysis between imaging modalities.
Neonatal patients with congenital heart defects (CHD) have changing physiology in the context of transitional period. Patients with CHD are at risk of low perfusion status or abnormal pulmonary blood flow. Near infrared spectroscopy has been used in neonatal intensive care units (NICU) to measure end-organ perfusion. The investigator plan on monitoring newborns with CHD admitted to the NICU with NIRS and echocardiography during the first week of life and correlate measures of perfusion from Dopplers to cerebral and renal NIRS.
Over the past four decades, it has become clear that childhood physical activity carries with it a myriad of beneficial effects. It is closely linked to quality of life and the recognized benefits include, but are not limited to, optimal growth and development, a healthier self-concept, enhanced peer socialization, and decreased anxiety and depression. Long term, an active lifestyle decreases the risk of many important physical and mental morbidities. Thus, the observation that children living with medical conditions and disabilities (MC&D) today, although surviving longer thanks to advances in medical care, are much less active than their peers is a matter of significant concern. Research indicates that the 350,000 Ontario children with MC&D have lower levels of physical activity, higher screen time and more frequent sleep problems. While the reasons underlying this reality are complex, previous research has identified a substantial subset of children who are motivated to be active but lack the confidence to do so. Fear of pain, concern for MC&D exacerbation and a lack of confidence in individual physical movement capacity contribute to their hesitation. Clinical experience suggests that these children represent 50% to 70% of inactive patients. Research indicates that being motivated to make a change and having the confidence that the desired change can be achieved are the essential precursors upon which successful behaviour change initiatives are built. This randomized, controlled trial will explore whether group sessions with a Registered Kinesiologist lead to a direct bolstering of physical activity confidence, and in turn to increased and sustained physical activity in these children. Such an approach holds the promise of a nonpharmacologic, low cost and accessible means of enhancing health that shall be met with a high level of patient and family support while bringing a significant societal and medical return on investment.
The purpose of this study is to refit habitual wearers of daily disposable contact lenses who currently experience symptoms of dry eye and discomfort during lens wear with a different type of daily disposable contact lens. Ocular signs and symptoms of dry eye will be assessed following the guidelines outlined by the Tear Film and Ocular Surface Society (TFOS) in the Dry Eye Workshop II (DEWS II). The performance of the habitual contact lenses and the study lenses will be determined using different optometric assessments. Study lenses will be worn for one month following a daily disposable wear schedule.
This study will examine the acceptability and effectiveness of using a stepped care treatment model, and specifically, the CBTm classes, in a rural population. The introduction of CBTm classes, developed in Winnipeg and used in outpatient mental health clinics there, is new to Adult Community Mental Health in the Prairie Mountain Health region. This research is being done to explore whether this is a treatment model that is effective at reducing symptoms of anxiety and depression and also whether it affects the workload for Community Mental Health Workers in a more rural area. Further, this research is being done to explore whether clients perceive this form of services to be useful and acceptable.
When a patient is received with the context of acute stroke, they undergo a fast neurological evaluation and obtain a basic appraisal composed of a non-contrast endovascular cerebral scan and an angiography scan of intracranial blood vessels and the neck. Once the structural lesion (hemorrhage, tumor, etc.) is absent, signs of early infracts and confirmed acute intracranial arterial occlusion, the possibility of a pseudo-stroke dwells in the differential diagnostic. Certain characteristics of history and clinical evaluation create sufficient doubt to evoke the possibility of a pseudo-stroke. In fact, this population is mostly female and the cardiovascular risk factors are less prevalent in this group than for the group of stroke victims. It is on average the youngest and presents a less severe deficit. For the rest, medical antecedents often help to evoke a diagnosis of pseudo-stroke.
This study compares two total knee replacement implants to asses muscle function and quality, and the immune response to the implants. 30 patients will receive the Smith and Nephew Journey II implant, while 30 patients will receive the Zimmer NexGen LPS-flex implant. 15 healthy controls will also be recruited and compared.
Background. First Nations peoples in Canada carry an increased respiratory health burden compared to non-First Nations. However, there is little accurate information of how many First Nations people have COPD, especially in remote and rural areas. Goal & Aims of the Study. The goal of this study is to estimate the burden of COPD in remote and rural First Nations communities. This project is a partnership between the University of British Columbia (UBC), Carrier Sekani Family Services (CSFS), and 13 First Nations communities in northern BC. Aim 1: Estimate the prevalence of COPD and the magnitude of underdiagnosis. Aim 2: Characterize the relationship between inhaled pollutants (from residential, occupational, and community/cultural sources) and: 1) symptoms; 2) airflow obstruction; and 3) health care utilization. Methodology. The investigators will recruit adults from randomly-selected households in 13 First Nations communities in northern BC. Detailed measurements of lung function, symptoms, self-reported exposure to lung irritants, air quality, and healthcare use will be collected. Expected Outcomes. This study will provide an accurate estimate of the prevalence of COPD and, using a culturally-relevant community-based research approach, will identify the contribution of risk factors to COPD in First Nations communities.
Social deprivation is a state to which older adults may be exposed, leading to adverse social, psychological, and health outcomes. Social deprivation may be more sensitive than socioeconomic status for predicting adversity while using only a few items for evaluation. However, there is no practical assessment for social deprivation in older Canadian adults. Two indices that capture a broad picture of social vulnerability have previously been developed for older Canadians. Using participants in the Canadian Longitudinal Study on Aging (CLSA), the overall objective is to examine and compare the associations of the COAD score and index, as well as the Keefe et al. and Andrew et al. indices with prevalent and incident adverse social, psychological, and health outcomes in participants at baseline assessment.
