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.
Studies show the presence of immuno-inflammatory disturbances in individuals with Bipolar Disorders (BD). Increased levels of circulating proteins known as cytokines that promote inflammation have been consistently reported in individuals with bipolar disorders. A particular cytokine referred to as Tumor Necrosis Factor (TNF)-alpha is among those cytokines that have been consistently identified across depressive, manic, and euthymic periods. Disturbances in inflammation however, are not seen in all individual with bipolar disorder. Those individuals with signs of inflammation also often present with higher prevalence of medical disorders that are also associated with inflammation. Those individuals with significant signs of inflammation may respond to anti-inflammatory treatments. In this study, individuals with bipolar depression who exhibit signs of high inflammation will be enrolled and treated with either an anti-inflammatory biologic known as infliximab or placebo (saline).
The main purpose of this research is to determine whether injecting mesenchymal precursor cells (MPC) into the heart during surgery to implant a left ventricular assist device (LVAD) is safe. MPCs are normally present in human bone marrow and have been shown to increase the development of blood vessels and new heart muscle cells in the heart. In addition, this research is being done to test whether injecting the MPCs into the heart is effective in improving heart function.
The purpose of this study is to determine if translocator protein total distribution volume (TSPO VT) is elevated in major depressive disorder that is not responding to medication and if adding minocycline can affect TSPO VT. Many remain treatment resistant with common antidepressant treatments and the investigators think it may be due to poor targeting of brain pathologies.
The purpose of this investigation is to determine the effect of a weighted compression vest in addition to usual medical care and exercise rehabilitation on cardiovascular, neurocognitive, balance and anxiety measures in individuals medically diagnosed with, and being treated for, a mild traumatic brain injury.
The purpose of this study is to document what course of action physicians choose for their patients when they develop taxane acute pain syndrome (TAPS) and to identify patients at the greatest risk of TAPS by examining specific human genome markers such as single nucleotide polymorphisms (SNPs) and Copy Number Variations (CNVs) that may explain the genetic (hereditary) component.
The purpose of this study is to describe the impact of treatment with adalimumab on work related productivity and economic burden in patients with Rheumatoid Arthritis (RA) treated in Canada.
Elevated intracranial pressure (ICP) is a common and potentially life threatening condition arising from a variety of pathological conditions. The ability to monitor ICP is a crucial aspect in the management of these patients. Currently, the diagnosis of whether ICP is elevated or not is determined either with clinical signs (headache, nausea and vomiting or visual disturbances) or from the changes in the preoperative neuroimaging modalities such as computerized tomography (CT scan) and/or magnetic resonance imaging (MRI). Recently, transorbital ultrasonography has gained popularity as a noninvasive bedside exam that has been shown to be useful in the diagnosis of raised ICP by evaluating the change in the optic nerve sheath diameter (ONSD). The aim of our study is to use transorbital ultrasound to evaluate ONSD changes in patients with intracranial pathology and to compare the changes in the ONSD before and after surgical intervention as well as between patients with and without clinical or radiological signs of increased ICP.
Elevated intracranial pressure (ICP) is a common and potentially life threatening condition arising from a variety of pathological conditions including traumatic brain injury (TBI), intracranial hemorrhage, subarachnoid hemorrhage and brain tumors. Monitoring the ICP is the most important aspect of the management of these patients. Recently, transorbital ultrasonography has gained popularity as a noninvasive bedside exam that has been shown to be useful in the diagnosis of raised ICP by evaluating the change in the optic nerve sheath diameter (ONSD). Transorbital ultrasonographic measurement of ONSD appears to be a noninvasive, relatively inexpensive bedside examination for the diagnosis of raised ICP. The investigators aimed to determine the changes in ONSD with acute controlled changes in ICP in healthy volunteers. The controlled changes in ICP will be produced by manipulating the PCO2 with the use of Respiract and jugular venous compression with the use of custom made neck collar.
Opioid naive patients are randomized to receive either TRAMACET or PERCOCET at the time of discharge following mild to moderate pain risk surgery. The following will be assessed: 1) Brief pain inventory (BPI) for the month. 2) Post operative pain management satisfaction. 3) Whether they sought any repeat opioid prescription. 4) Whether they intend to seek repeat opioid prescription. It is expected that both groups will have similar pain outcomes but those patients in the Percocet group will be more likely to seek a second prescription.
This randomized phase III trial compares memantine hydrochloride and whole-brain radiotherapy with or without hippocampal avoidance in reducing neurocognitive decline in patients with cancer that has spread from the primary site (place where it started) to the brain. Whole brain radiotherapy (WBRT) is the most common treatment for brain metastasis. Unfortunately, the majority of patients with brain metastases experience cognitive (such as learning and memory) deterioration after WBRT. Memantine hydrochloride may enhance cognitive function by binding to and inhibiting channels of receptors located in the central nervous system. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Using radiation techniques, such as intensity modulated radiotherapy to avoid the hippocampal region during WBRT, may reduce the radiation dose to the hippocampus and help limit the radiation-induced cognitive decline. It is not yet known whether giving memantine hydrochloride and WBRT with or without hippocampal avoidance works better in reducing neurocognitive decline in patients with brain metastases.
