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.
Age-related vision impairment and dementia both become more prevalent with increasing age. Research into the mechanisms of these conditions has proposed that some of their causes (e.g., macular degeneration/glaucoma and Alzheimer's disease) could be symptoms of an underlying common cause, or may be equally linked to a multifactorial context in frailty and aging. Research into sensory-cognitive aging has provided preliminary data that sensory decline may be linked to the progression of dementia through the concept of sensory deprivation. Preliminary data in hearing loss rehabilitation support the idea that improved hearing may have a beneficial effect on cognitive functioning; however, there are to date no data available to examine whether low vision rehabilitation, specifically for reading, could have an equally protective or beneficial effect on cognitive health. The present proposal aims to fill this gap.
We defined a new and early condition in the spectrum of cognitive frailty: the "cognitive-prefrailty" which is a combination of prefrailty stage and subjective cognitive impairment (SCI). This study aims to: (1) examine and compare the prevalence of cognitive-prefrailty, cognitive frailty and motoric cognitive risk syndrome (MCR) syndromes in participants of the Canadian Longitudinal Study of Aging (CLSA) using the (tracking and comprehensive) baseline assessment, (2) examine the association of cognitive-prefrailty, cognitive frailty and MCR syndromes with incident adverse health events using the information collected during the first CLSA 18-month follow-up, and (3) compare the criteria performances (i.e., sensitivity, specificity, positive predictive value, negative predictive value, area under receiver operating characteristic curve, positive and negative likelihood ratio) for incident adverse health events of the cognitive-prefrailty, cognitive frailty and MCR syndromes.
Allogenic plasma aliquots, used as eye drops, will provide a source of plasminogen in the treatment of ligneous conjunctivitis. The investigational product will be available through written request from the Sponsor-Investigator to Canadian Blood Services, as approved by Health Canada.
This study will evaluate the feasibility of three times weekly symptom reporting by children using the SPARK platform for 8 weeks. SPARK is a web-based application that promotes symptom screening for children receiving cancer therapies and enables access to clinical practice guidelines for symptom management. Newly diagnosed and relapsed patients with cancer will be enrolled. Children will be prompted to complete symptom screening three times weekly via SPARK with corresponding feedback sent to their healthcare providers with each completed assessment. Symptom reports will contain links to clinical practice guidelines for symptom management. Active intervention will last for 8 weeks starting from the date of enrollment.
Performing resistance training and impact exercise at a moderate to high intensity may help prevent bone loss. However, medications used to treat bone diseases such as osteoporosis reduce the activity of bone cells. The investigators are unsure whether bone cells will still respond to exercise in people on osteoporosis medications. Therefore, investigators have designed a study to compare bone response to moderate-high intensity exercise that involves resistance training and impact exercise versus posture and low intensity balance exercises. Women taking osteoporosis medication will be equally and randomly assigned to one of the exercise groups. There will be 23 participants per group and both exercise programs will be performed over a span of 6 months, twice weekly, for approximately 30-45 minutes per session. Investigators will measure sclerostin, a bone-related protein found in the blood, to see if there are any changes after 3 months of training. Higher levels of sclerostin may result in greater bone breakdown. It is expected that the moderate-high intensity exercise program will decrease sclerostin levels more than low intensity training. Further, changes in sclerostin levels during the 6-month exercise intervention will be explored. The effects of the exercise program on other bone markers in the blood, physical ability, and quality of life will be reported. The willingness of the participants to perform the exercise program and the safety of the exercises provided will also be assessed.
Psychological factors such as stress, distress, anxiety, depression, and poor coping strategies may be associated with ongoing pain following injuries such as fractures. To study this relationship, patients will undergo cognitive behavioural therapy (CBT) which is designed to modify such thoughts with the goal of reducing ongoing pain and improving quality of life. The goal of this study is to determine if CBT, versus usual care, reduces the prevalence of moderate to severe persistent post-surgical pain (PPSP) over 12-months post-fracture in patients with an open or closed fracture of the appendicular skeleton, treated with internal fixation.
The purpose of this study is to demonstrate superiority of macitentan 75 milligrams (mg) in prolonging the time to the first clinical events committee (CEC)-adjudicated morbidity or mortality (M/M) event in participants with symptomatic pulmonary arterial hypertension (PAH) compared to macitentan 10 mg.
The aim of this project is to test the effects of an environmental factor (mild stress) on prefrontal cortex (PFC) and the cognitive functions that depend on PFC (collectively called executive functions [EFs]), and to test our predictions concerning how those effects differ by biological factors (hormones and genotype). To test our hypotheses concerning mechanism, the investigators will model the effects of mild stress on EFs pharmacologically. The purpose is to pharmacologically model the effects of mild stress on the cognitive functions (collectively called "executive functions" [EFs]) dependent on the frontal lobe. The investigators would also like to investigate how gender differences and genotype mediate the effect of methylphenidate (MPH) on EFs.
Currently international experts recommend therapeutic anticoagulation for veno-venous extracorporeal membrane oxygenation (VV-ECMO). Reports and case series suggest that the absence of therapeutic anticoagulation is safe for VV-ECMO. No randomized control trials have assessed this. The aim of this pilot study is to assess safety and feasibility of an "anticoagulation-free strategy" for veno-venous ECMO (VV-ECMO) in Acute respiratory distress syndrome (ARDS).
This study will investigate the effects of atezolizumab on select cancer types in people whose analysis of tumour DNA and RNA indicates they may be sensitive to atezolizumab. This study aims to determine if the information from the cancer genome analysis corresponds with the effects of atezolizumab on individuals and their cancer. This is a Phase 2 study, which is undertaken after preliminary safety testing on a drug is completed, and will involve approximately 200 participants. Participants are assigned to one of 8 cohorts based on their primary tumour type: breast, lung, gastrointestinal (GI), primary unknown, genitourinary (GU), sarcoma, gynecological, and 'other' cancer types. Participants in all cohorts will receive the same dose of atezolizumab (1200 mg every 3 weeks). In the first stage for each cohort, 8 participants will be enrolled and if no participants respond to treatment, enrollment to that cohort will be closed. If 1 or more participants respond to treatment, up to 16 additional participants will be enrolled to that cohort. Participants continue on treatment until they no longer may benefit from the treatment or they decide to stop treatment.
