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 aims to investigate the optimal oxygen flow rate needed during tracheal intubation with the C-MAC video laryngoscope (Karl Storz, Tuttlingen, Germany) using Miller-blade or Macintosh-blade size No. 0 or No. 1 in the operating room or intensive care unit. The investigators hypothesize that the difference between low-flow and high-flow supplemental oxygen is negligible.
Non-alcoholic fatty liver disease (NAFLD) is one of the most common liver diseases, affecting 25% to 30% of the global population and nearly one third of the population in North America. NAFLD is defined as an excessive accumulation of lipids within hepatocytes in the absence of significant alcohol consumption or other causes of chronic liver disease. These patients usually present with hepatic steatosis observed on imaging studies and elevated liver enzymes with clinical features of insulin resistance (IR), including pre-diabetes, type 2 diabetes mellitus (T2DM), arterial hypertension, dyslipidemia, and visceral obesity. The minimum criterion for a histologic diagnosis of NAFLD is >5 percent steatotic hepatocytes in a liver tissue section. The exact mechanism for the development of NAFLD is unclear, although the current evidence indicates that it is likely a complex interplay among neurohormones, intestinal dysbiosis, nutrition, and genetics. IR plays a crucial role in NAFLD pathophysiology mainly by increasing adipocyte lipolysis, resulting in the circulation of more free fatty acids available for hepatic uptake and increasing hepatic de novo lipogenesis. There is yet no approved pharmacologic option for the treatment of NAFLD. Current international guidelines on NAFLD emphasize the importance of lifestyle modifications for all patients with NAFLD and recommend 7-10% of weight loss and a "healthy diet", without suggesting any particular diet. Recent data provide some support for the beneficial role of low carbohydrate (CHO)/high unsaturated fatty acid (both monounsaturated (MUFAs) and polyunsaturated (PUFAs)) dietary patterns for decreasing hepatic steatosis. This proposal addresses this important research gap by leading to advances regarding the impact of a short-term low CHO/high PUFAs/MUFAs dietary intervention on improving hepatic gene expression profiles and lipid composition in individuals with pre-diabetes. The proposed study is unique because all meals and foods will be provided to participants under carefully controlled isocaloric conditions to maintain a constant bodyweight with optimal energy and macronutrient intake control. The primary objective of the proposed research is to investigate how replacement of dietary CHOs by unsaturated fatty acids (both PUFAs and MUFAs) affects liver fat composition and liver transcriptomics in subjects with pre-diabetes.
Transcranial Ultrasound Stimulation (TUS) is an emerging non-invasive brain stimulation(NIBS) technique that can be used on both superficial and deep brain targets with a high spatial resolution as small as a few cubic millimeters. Neural correlates of TUS have yet been elucidated. To date, no intracranial recordings (i.e., local field potential [LFP]) have been captured during or after TUS in patients with movement disorders. In this study, we are aiming to profile basal ganglia LFP activity during and after TUS by using a DBS system that is capable of recording LFP. This can shed light on mechanisms of TUS, as well as allow identification of a neurophysiological biomarker that can be used to tune the TUS sonication parameters for future clinical trials.
This is a parallel arm randomized (1:1) controlled trial. Adolescents aged 12-17 years (n=452) that did not respond or tolerate first-line fluoxetine therapy will be randomly allocated to receive 12-weeks of pharmacogenetic-guided antidepressant therapy (experimental intervention) or GLAD-PC guided prescribing (control intervention).
This is a multi-center randomized, double-blind, placebo-controlled, parallel, 4-arm study of nalbuphine ER (NAL ER). After meeting eligibility during the Screening Period, subjects will be randomized (1:1:1:1) to one of four treatment arms. - Arm 1: Placebo - Arm 2: 27 mg nalbuphine ER - Arm 3: 54 mg nalbuphine ER - Arm 4: 108 mg nalbuphine ER Each arm will be titrated to their fixed dose during the blinded 2-week Titration period followed by the 4-week Fixed Dose Period for a total of 6 weeks on drug.
The most accurate way to determine intra-aortic BP is to obtain invasive measures by vascular catheterization, which is not possible to perform routinely during the regular follow-up of patients. However, in recent years, devices used to estimate central BP have been designed and approved for clinical use. These devices can determine aortic BP in a non-invasive way using various techniques and algorithms and offer a high degree of precision when compared to invasive measurements of intraaortic BP. On the other hand, certain characteristics specific to the different devices mean that the central BP values obtained may not be interchangeable. It is therefore important to determine the degree of agreement of central BP values obtained using commercially available devices. This study aims to determine the degree of agreement between central BP measurements obtained using 4 devices commonly used to measure central blood pressure, i.e. Mobil-o-Graph NG (IEM, Germany), WatchBP Office (Microlife, Taiwan), Oscar 2 with SphygmoCor inside (SunTech, USA) and BP+ (Uscom, Australia). These four devices record the shape of the pulsatile wave and then derive the central BP using an algorithm. The main differences between these devices lie in this algorithm, or "transfer function,", which is unique to each and the calibration used. All use a brachial cuff to capture the pulse waveform and can easily be used in clinical practice.
LAAOS-4 aims to determine if catheter-based endovascular left atrial appendage occlusion prevents ischemic stroke or systemic embolism in participants with atrial fibrillation, who remain at high risk of stroke, despite receiving ongoing treatment with oral anticoagulation.
The goal of this observational study is to better understand the role of the brain in chronic low back pain patients.
The purpose of this clinical trial is to evaluate the impact of an online group intervention called Healthy Minds in facilitating a sustainable return to work for individuals with a mood disorder. The study aims to answer the following key questions : - Does receiving the Healthy Minds online intervention lead to a more sustainable return to work compared to not receiving the intervention? - Are the health outcomes (e.g., depressive symptoms) and work-related outcomes (e.g., work functioning) of individuals who receive the Healthy Minds online intervention better than those who do not receive the intervention in the year following the intervention? Both experimental and control participants will be recruited at baseline while on sick leave (expected to return to work in less than one month) or recently returned to work (less than one month). Participants will complete a series of online questionnaires at the following time points : - Baseline - First follow-up (2 months after baseline) - Second follow-up (6 months after baseline) - Third follow-up (12 months after baseline) The questionnaires will cover the following areas : - Sociodemographic and biopsychosocial factors - Symptoms associated with the primary mood disorder - Cognitive difficulties and biaises - Self-efficacy related to return to work - Work accommodations and natural supports - Relationship with immediate supervisor - Work functioning - Return to work time (number of days away from work) Experimental participants will participate in the 2-month online Healthy Minds group intervention (cohort of 5 participants) between the baseline assessment and the first follow-up. The intervention consists of 8 sessions (one per week for 8 weeks), with each session focusing on a specific aspect of the return-to-work process from a cognitive-behavioral perspective.
