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.
EEG signals have been collected and studied since the early 1990's as a way of assessing brain function at a gross level. As early as the 1930's a derivative of the raw EEG signal - event-related potentials (ERPs) - have been computed. These scalp-recorded ERPs are the brains response to a stimulus of interest (e.g. a flashing checkerboard or an angry face). The timing and topographical location of ERP components lends insight into the timing and complexity of various cognitive processes. At NeuroCatch Inc., research is primarily focused on three ERP components: the N100, P300 and N400. To elicit the ERP components of interest in this study (N100, P300, N400), proprietary auditory stimulus sequences will be administered using the investigational device, the NeuroCatch Platform™. Each sequence consists of pure tones and word pairs to elicit the various components associated with different attention abilities (sensory processing, target detection & semantic processing). A secondary objective of the study will be to validate the auditory stimulus sequences tested. Understanding the degree to which these neurophysiological components fluctuate over time is crucial to our understanding of typical brain functioning. Research and medicine is moving away from behavioural responses to assess brain health (e.g. verbal responses, reaction time, etc.) and are moving toward more neuroimaging focused measures, such as CT, and MRI scans. The strength of utilizing EEG technology is two-fold: i) it is portable and ii) has high temporal resolution. Looking forward, EEG-based brain assessment technology could be implemented field-side, at the site of an accident for a quick assessment of brain and cognitive functioning, or within a clinicians' office to evaluate treatment efficacy. However, for this type of technology to be useful in quantifying brain health, we must first quantify the degree to which a healthy brain naturally fluctuates in it processing capability. For example, should technology such as the NeuroCatch Platform™ be used as a monitoring tool, we must have an idea of what normal variation is.
Hazardous alcohol consumption is common among people suffering from depression. There are effective Internet interventions that target hazardous alcohol consumption or depression separately but none that combine these online interventions without the involvement of a therapist. This study aims to evaluate the effects of combining an Internet intervention targeting hazardous alcohol consumption with one for depression on drinking and depressive symptoms.
Inappropriate prescription of unnecessary and potentially harmful medications continues to be a widespread problem for hospitalized patients. The investigators aim to study the prescription patterns of several classes of medications featured both in the Canadian Choosing Wisely campaign and the Beers Criteria for medication1,2. Specifically, this study will be looking at the patterns of sedatives (includes benzodiazepines, sedative-hypnotics, and sedating antipsychotics) prescriptions over time. The investigators aim to determine how closely these recommendations are adhered to on medical-surgical wards at five local hospitals (Sinai Health System, Toronto General Hospital, Toronto Western Hospital, Sunnybrook Health Sciences Center, and St. Michael's Hospital); and to observe trends in prescribing before and after hospital-wide quality improvement initiatives.
This research project concerns the evaluation of the Metabolic Hyperspectral Retinal Camera (MHRC), a novel medical instrument from Optina Diagnostics, for the detection of beta-amyloid plaques, a hallmark of Alzheimer's disease (AD), in the retina. The experimental device, produces multiple images of the retina when subjected to light in very specific colors (90-100 specific colors typically) and may be used to identify specific biomarkers based on their unique spectral signature. The retina is an extension of the brain and is the only optically accessible nervous tissue. The MHRC could represent a simple and non-invasive tool to facilitate the diagnosis of AD.
The Scleroderma Patient-centered Intervention Network (SPIN) is an organization established by researchers, health care providers, and people living with scleroderma (systemic sclerosis or SSc) from Canada, the USA, and Europe. The objectives of SPIN are (1) to assemble a large cohort of SSc patients to complete outcome assessments regularly in order to learn more about important problems faced by people living with SSc and (2) to develop and test a series of internet-based interventions to help patients manage aspects of their disease, including hand limitations. In SSc, approximately 90% of patients experience significant hand function limitations, which impact overall disability more than any other aspect of the disease. The SPIN hand exercise program was designed by SPIN experts in rehabilitation, behavioural therapies, and e-health interventions, as well as patient representatives in SPIN. The program core consists of 4 modules that address specific aspects of hand function, and integrates tools to support key components of successful self-management programs, including goal-setting and feedback, social modeling, and mastery experiences. The SPIN-HAND trial is a pragmatic randomized control trial (RCT) embedded in the SPIN Cohort that will evaluate the effect of SPIN's online hand exercise program, in addition to usual care, on hand function and health related quality of life (HRQL) in SSc patients with at least mild hand function limitations. SPIN will randomize 586 SPIN Cohort participants with at least mild hand function limitations and an indicated interest in using an online hand exercise program to be offered the hand exercise program or usual care only.
The erector spinae plane (ESP) block is a novel regional anesthetic technique for the treatment of thoracic, cervical, and abdominal pain. This pilot study aims to investigate the post-operative analgesic effectiveness of ultrasound guided single-shot ESP blocks for patients undergoing minimally invasive thoracoscopic wedge resections of the lung in comparison to those receiving conventional parental opioid analgesia alone. This will be achieved through the use of objective measures including quality the 40 point Quality of Recovery assessment (QoR-40) on postoperative day (POD) 1, visual-analogue pain scale (VAS) in the post-anesthetic care unit (PACU) and at POD 1, and oral morphine-equivalent (OME) opioid consumption in the PACU and at 24 hours post-operatively.
Sickle cell disease (SCD) is a genetic disease characterized by abnormal hemoglobin, the main constituent of red blood cells. People with SCD have nutritional deficiencies, and vitamin D deficiency is one of the most common. Symptoms of vitamin D deficiency are similar to those of SCD and include chronic pain and bone complications. Correcting vitamin D nutrition of children with SCD represents a treatment that will improve their health. A single oral high-dose of vitamin D3 will be given to SCD children during one of their follow-up visits at the SCD clinic of CHU Sainte-Justine, Montreal, Canada. This mode of administration was chosen to ensure a better adherence to the treatment. The investigators will determine whether this dose is safe and its administration feasible in clinic. The impact of this dose on blood vitamin D and calcium, urinary calcium, growth, inflammation, bone health, pain and quality of life will also be assessed. This study intends to propose a new intervention to improve the nutrition of children with this disease.
The purpose of this study is to collect feedback on imaging guidance adequacy from physicians who use the OEC™ Elite CFD Mobile Fluoroscopy System—Motorized Configuration to perform surgical procedures for which the use of mobile fluoroscopy is prescribed per standard of care. Up to 40 eligible subjects will be enrolled and have their clinically indicated procedure completed using the investigational device. Following completion of each subject's procedure, the investigators will complete a User Survey specific to the workflow and guidance adequacy of the OEC Elite device. The survey will consist of a series of questions on the use of the system as well as anonymized image data. After all subjects' procedures are completed at a given site, the site investigator will review survey data from the study subjects enrolled at the site and document his/her assessment of the overall acceptability of the system for use in a clinical environment. There is no statistical hypothesis being tested in this study. Results will be summarized using descriptive statistics.
Approximately 30% of community-dwelling older adults experience one or more falls per year, resulting in injuries, loss of independence, and reduced quality of life. While there are known physiological risk factors for falls, including poor balance and altered gait patterns, it is now recognized that impaired cognitive functioning is also a risk factor for falls. Within the broad construct of cognition, one specific domain that has been focused on in the falls literature is attention. The literature suggests that improving attention in those at-risk for falls may reduce older adult's risk of falling.
The purpose of this study was to determine the frequency of bleeding episodes in participants receiving fitusiran as prophylactic treatment of hemophilia compared to participants who were assigned to continue with their regular medication. In addition, the study assessed safety, quality of life, pharmacodynamics (PD), and pharmacokinetics (PK).
