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.
To assess the efficacy of multiple dupilumab (REGN668/SAR231893) dose-regimens, compared to placebo, in adult patients with moderate-to-severe atopic dermatitis (AD).
Patients undergoing renal transplantation at London Health Sciences Centre, University Hospital and who are participating in the study "A Comparison of Effects of Standard Dose vs Low Dose Advagraf with IL-2 Receptor Antibody Induction, MMF and Steroids, With or Without ACEi/ARB-based Antihypertensive Therapy on Renal Allograft Histology, Function, and Immune Response" will be evaluated with the ImmuKnow Assay to assess the ability of this assay to predict underimmunosuppression (rejection) or overimmunosuppression determined by this test and to determine retrospectively whether decision making utilizing this novel assay would have improved outcomes over standard techniques. This study is designed to evaluate an in vitro assay (Cylex®ImmuKnow Assay) for the measurement of cell-mediated immune response in renal transplant patients receiving immunosuppressive therapy. This assay measures ATP as an activation response of CD4+ cells to stimulation with phytohemagglutinin (PHA) in whole blood samples as a reflection of the immune system of the patient at any point in therapy. The natural history of the immune status of the renal transplant recipient as reflected by the ImmuKnow assay will be determined at specific time points of interest including: pre and post transplant, as an adjunct to therapeutic drug monitoring, and pre and post infectious or rejection episode. Analysis of the results of the assay at these time points will allow us to retrospectively study the effects of routine immunosuppressive agent modulation on immune function, and its subsequent effects in times of renal allograft insult.
To determine whether women exposed to the continence promotion intervention will report improved urinary symptoms and quality of life, and lower incontinence-related stigma and falls than women who receive a control intervention at one-year post-intervention.
Hypertensive disorders of pregnancy happen in 5% of pregnancies. Being aware of symptoms and complications may help women to present early and preserve their own and their baby's health. The proposed research aims to evaluate the impact of educational tools in pregnant women from an ambulatory population. These tools include a detailed pamphlet (including a graphic-based summary), a magnet summarizing symptoms and appropriate action, and a video. Level of knowledge will be evaluated after one month with a validated questionnaire. We will also evaluate if getting more information about preeclampsia increases patient anxiety as well as satisfaction about the tools.
This study will evaluate dose escalation of melatonin in pediatric oncology patients with relapsed solid tumors. The purpose of this study is to determine the safety of melatonin at a dose up to 20 mg daily, as well as to determine the maximum tolerated dose of melatonin.
Children are distressed at anesthesia induction and this distress can result in maladaptive recovery outcomes. Having parents be present at anesthesia induction (PPIA) has been suggested as a potential intervention to decrease children's distress, and this intervention is widely favored by parents. However, to date, PPIA has not been found to be effective in reducing children's anxiety. The lack of efficacy may be attributable to the fact that parents have generally not been prepared for PPIA. The one study that prepared parents (as part of a larger preoperative preparation program) found that PPIA with preparation was superior to PPIA as previously studied (without preparation). Unfortunately, this program is resource intensive and therefore is not clinically feasible. This study will compare PPIA with a clinically feasible preparation program to PPIA with standard care (minimal preparation). Should our intervention show evidence of efficacy, the investigators will have designed a program that is easily translatable to everyday clinical practice. This will, in turn, reduce children's anxiety, improve postoperative outcomes and increase parental satisfaction.
Adrenal androgens are serum biomarkers of interest that may help guide abiraterone acetate treatment, particularly at the time of progression. Biomarkers may also help identify pathways to resistance of abiraterone acetate treatment. The most practical way of approaching this question is to explore surrogate biomarkers of prostate cancer including quantification of pharmacodynamic endocrine biomarkers.
The purpose of this study is to determine the effectiveness of a pre-consultation decision support workshop for breast reconstruction after breast cancer, in facilitating the decision-making process, compared to routine pre-surgical education.
Laparoscopic surgery has become the standard approach to a vast variety of surgical procedures. Due factors such as 2D- to 3D conversion, reduced tactile sensation, amplification of tremor and fulcrum effect of the abdominal wall, surgeons require a different set of skills than in open access surgery. Acknowledging this, several comprehensive curricula have been developed to teach basic skills as well as advanced laparoscopic procedures. Despite a recent emphasis on early exposure of medical students to surgery no designated curricula have been developed to introduce medical students to the technique of laparoscopic surgery. Participation in an introductory curriculum in laparoscopic surgery results in improved cognitive and technical performance compared to self-directed learning. The greater homogeneity and fewer dropouts amongst those in the curriculum group suggest that a structured curriculum is essential in ensuring standardization of clinically relevant training. An introductory curriculum for medical students should be delivered in a structured and standardized fashion prior to clinical exposure in order to maintain motivation and enhance learning.
AVMs are abnormal collections of blood vessels which can occur in any part of the body including the lungs. These blood vessels are weakened and can rupture anytime causing bleeding which can be massive, leading to life-threatening conditions. Pulmonary AVMs occur in about 40% of patients with HHT. Each patient may have an average of 5 AVMs .Rupture of the AVM can lead to massive bleeding in the lung, stroke and infection of the brain. In order to prevent these complications, patients with HHT are routinely examined for pulmonary AVMs and treatment with embolization is recommended. AVMs have a main blood vessel or artery supplying blood to the collection of blood vessels. The way to treat AVMs is cut off their blood supply through a process called embolization. Embolization is a standard medical procedure which is done to stop or prevent hemorrhage (bleeding) from an AVM. It involves blocking the artery that supplies blood to the AVM by inserting a foreign body, into the blood vessel supplying blood to the AVM. Standard devices used for embolization include coils (made of stainless steel or platinum). These devices usually have a good success rate for blocking the artery that supplies blood to the AVM. However, a few AVMs that are embolized by standard devices may reopen over time. This is called reperfusion and will require repeat embolization procedures. For embolization of pulmonary AVMs at St. Michael's Hospital, the Nester coil is used. In this study, we would like to compare the Nester coil with a new coil device called the Interlock Fibered IDC Occlusion System. Both coils are approved for use in Canada, however the cost of the IDC coil limits its use at this hospital. Compared to the Nester coil, the IDC coils are made so that they can be removed or repositioned if they are not placed correctly. The coil also allows tighter packing which helps prevent reperfusion. This study will compare the success rate of embolization between the Interlock™ Fibered IDC™ Occlusion System (IDC coil) and the Nester coil.
