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.
It has been suggested that obesity occurs because the colonic microbes in obese individuals, compared to those who are lean, produce more short chain fatty acids during the fermentation of dietary fiber; this means that obese individuals obtain more energy from dietary fiber than lean. On the other hand, it is possible that the ability of colonic short chain fatty acids to improve glycemic control and suppress appetite may be reduced in obese subjects. The aim of this study was to determine the acute effects of 2 fibers commonly used as food ingredients, inulin and resistant starch, on postprandial serum responses of short chain fatty acids, glucose, insulin, free-fatty acids and selected gut hormones in lean and overweight or obese subjects.

The purpose of this study is to demonstrate bioequivalence between the test drug product, fulvestrant Injection, 50 mg/mL, and the Reference Listed Drug, Faslodex® Injection, 50 mg/mL.
This study evaluates NP001 in patients with amyotrophic lateral sclerosis (ALS) and evidence of systemic inflammation. Half of participants will receive NP001 and the other half will receive placebo.
Migraine recurrence is common amongst pediatric patients being discharged from the emergency department after treatment for migraine. Despite the commonality of migraine recurrence within the week following discharge, no known effective therapies are available in the pediatric population, though dexamethasone has been established as efficacious in the adult migraine population. The proposed study will randomly assign children and adolescents visiting the emergency department (ED) for migraine to receive either one dose of oral dexamethasone or oral placebo. Twenty patients will be recruited to this randomized, double-blind, pilot trial over a 6 month period, and the aim of the study will be to determine the feasibility and acceptability of the protocol.
The primary aim of this research is to evaluate a community-based exercise (CBE) intervention for adults living with HIV within the community with the goal of reducing disability and enhancing health (cardiopulmonary, strength, weight and body composition, and neurocognitive outcomes) and contextual factor outcomes (social support, stigma, mastery, coping) for adults living with HIV.
The purpose of this study is to characterise long-term safety and tolerability of intravenous anifrolumab.
Procedural pain is the most intense and often undertreated pain associated with burn injuries. The use of analgesics does not always provide optimal relief and is accompanied by several side effects. Indeed, children with burn injuries still experience severe pain intensity during procedures despite the fact that doses of analgesics used with this population has almost doubled in the last twenty years. Current guidelines on pediatric procedural pain management recommend the combination of non-pharmacological and pharmacological interventions to enhance pain management and decrease the numerous side effects of analgesics. Distraction has been identified among the most effective non-pharmacological interventions for pain as it diverts the child's attention to an attractive element, hindering the perception of the painful stimuli. Virtual reality (VR) is a method of active distraction that offers the child a multi-sensory immersive interaction that found many applications for pain management in adult patients. However, very few studies have tested the efficacy of distraction by virtual reality on procedural pain and anxiety in children with burn injuries. The aim of this study is to assess the feasibility and preliminary efficacy of a virtual reality prototype developed specifically for the hydrotherapy room of children under seven years old for the relief of procedural pain and anxiety in children with burn injuries. HYPOTHESES: a) VR distraction is a feasible non-pharmacological intervention for pain management during hydrotherapy, b) VR distraction combined with analgesics is more efficacious than standard treatment (analgesics alone) on procedural pain and anxiety (hydrotherapy) of young children with burn injuries.
Breast conservation surgery (BCS) is performed on patients with breast cancer with the intent to resect and completely remove the tumour while conserving as much of the surrounding normal tissue as possible. Currently, there is no way for surgeons to determine the adequacy of surgical resection in real-time during surgery; the assessment of surgical margins requires histological examination that is not available in real-time and is impractical in most clinical cases. This results in a re-excision rate of 23% among Canadian women in order to achieve optimal surgical margins. In addition, the presence or absence of cancer in tumor draining lymph nodes is recognized as a key element for breast cancer staging; however, lymph node dissection can be associated with overtreatment and morbidity (nerve damage and post surgical lymphedema) and histological analysis of nodes can be time consuming and thus delay subsequent procedures. In an effort to address these issues, we have designed and constructed, in collaboration with Sogang University, Seoul, S. Korea, a novel imaging system that performs three complementary imaging modalities (tri-modal): ultrasound (US), photoacoustic (PA) and fluorescence (FL). This first-in-human pilot study will recruit 10 breast cancer patients undergoing breast conserving surgery at Princess Margaret Hospital (Toronto, Canada). The study is designed to test our tri-modal (US, PA, FL) imaging technology in breast cancer patients. The overall goal is to obtain initial information on the technical feasibility of the tri-modal system in a peri-operative setting and to confirm the anticipated safety of the procedures. Additionally, it will provide initial data on the ability of this system to detect/localize primary breast cancer lesions and cancer-involved lymph nodes prior to surgery.
1.0 Background & Introduction Positron emission tomography / computer tomography (PET/CT) is a nuclear medicine procedure based on the measurement of positron emission from radiolabelled tracers. This technology allows biologic processes to be visualized and measured on whole body images. Common radiotracers in use today in the USA and Europe are radiolabelled choline derivatives such as the analogs 18F-fluoromethylcholine (FMCh) and 18F-fluoroethylcholine (FECh), or more broadly FCH. Both of these fluorinated choline analogs have been extensively studied and display seemingly identical biological, radiopharmaceutical and radiochemical properties. Both have been extensively studied in human prostate cancer, with FMCh having slightly more published data than FECh. Imaging with radiolabelled choline derivatives is used to determine sites of abnormal choline metabolism and can be used to characterize prostate cancer, for which there is extensive data in the literature. PET/CT with radiolabelled choline derivatives is considered standard of care by some experts where available, however at the JGH, anatomic imaging with CT and MRI, and bone scan are the current diagnostic imaging modalities in use for this patient population. Prostate cancer cells have increased choline uptake compared to normal tissues, forming the molecular basis for this technique. The Gleason score, a histopathologic measure of tumor aggressiveness, is one of the most important prognostic factors in the disease. The objective of this study is to evaluate if the degree of uptake measured by maximum standard uptake value (SUVmax) on FCH PET/CT in prostate cancer correlates with Gleason score at initial biopsy. 2.0 Study Objectives The objective of this study is to evaluate if the patient-wide SUVmax on 18F-FCH PET/CT in locoregional and metastatic prostate cancer correlates with histopathologic Gleason score at initial biopsy. It is hypothesized that SUVmax will correlate positively with Gleason score. This is of interest because non-invasive risk stratification may be possible in the future. 3.0 Study Design This will be a single-site JGH-only open label study in which one (1) 18F-FCH PET/CT will be performed on study participants. A PET/CT scan takes about 3 hours. 4.0 Safety & Ethics The radiation dose to patients from fluorinated choline derivatives compares favorably to the major PET tracer in widespread clinical use, 18F-fluorodeoxyglucose (18F-FDG). The safety of fluorinated choline derivatives is not disputed and the investigators expect the number of adverse events in this study to be at (or near) zero. There is no established toxicology for diagnostic doses of fluorinated choline derivatives. There are no salient ethical considerations identified. The treating physicians are free to order any diagnostic or therapeutic intervention on study patients, and care will not be modified or restricted in any way. Treating physicians are free to incorporate information acquired with this study or discard it if it is not relevant. Care of the patients may be improved with additional information provided by FCH PET/CT, but it is otherwise unchanged. No vulnerable populations will be included in the study. 5.0 Confidentiality All information (medical history, physical examination, and PET/CT results) will be kept strictly confidential and only authorized personnel will have access. The reports of the PET/CT will be contained in a password protected radiology & nuclear medicine RIS database (RadImage) where all other diagnostic imaging reports are securely stored. Clinical PET/CT reports will be stored indefinitely, whereas all other study data will be kept locked by the PI and destroyed after 10 years. 6.0 Population, Sample Size and Recruitment A maximum of 225 competent adult male medically stable prostate cancer patients with available Gleason Scores will be entered into the study. Patients will be recruited by urologists in the clinical setting. Initial contact and consent will be by the department of urology.
