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.
Many individuals with schizophrenia struggle with auditory verbal hallucinations (AVHs). In some cases, these AVHs can be resistant to medication treatment. Previous research has found that transcranial direct current stimulation (tDCS) can be helpful in treating symptoms in individuals with other psychiatric disorders, such as depression. This study will assess if tDCS is effective in treating AVHs in individuals with schizophrenia. tDCS is a non-invasive form of brain stimulation which uses a weak current to temporarily excite or inhibit underlying cortical regions with small electrodes placed on the scalp. tDCS has been found to improve mental processes, including attention and memory function. In addition to examining the effect of tDCS on AVHs, this study will assess the effects of tDCS on mood as well as brain electrical activity with electroencephalogram (EEG) recordings. As an additional component, participants will be invited to participate in neuroimaging. Using magnetic resonance imaging (MRI), brain activity and structure will be examined before and after tDCS. tDCS will be administered twice daily for 5 consecutive days for a total of 10 sessions. These study findings will contribute to the understanding of the impact of tDCS on AVHs, and will also increase knowledge of sound and memory/cognitive processing in individuals with schizophrenia.
The purpose of this study is to evaluate the efficacy and safety of pembrolizumab plus concurrent chemoradiotherapy compared to placebo plus concurrent chemoradiotherapy in participants with locally advanced cervical cancer. The primary hypotheses are that pembrolizumab plus concurrent chemoradiotherapy is superior to placebo plus concurrent chemoradiotherapy with respect to progression-free survival and overall survival. Once the study objectives have been met or the study has ended, participants will be discontinued from this study and will be enrolled in an extension study to continue protocol-defined assessments and treatment.
Acute kidney replacement therapy (i.e., dialysis) is used in 6-10% of patients admitted to intensive care units (ICUs). The amount of acute kidney replacement therapy use has increased in Canadian ICUs over the last several years. Continuous renal replacement therapy (CRRT) remains the most common form of acute renal replacement therapy used in ICUs. Many different parts aspects of CRRT lack a usual way to be done, and because of this, are done differently in different ICUs. Not having generally accepted markers of the performance and delivery of CRRT is a main reason that we have these practice difference. This is an important gap in the way that clinicians deliver this important ICU therapy and is a main focus of ongoing research in ICU and dialysis. The proposed project is a continuation of a program of work that first reviewed the current state of the quality and safety in ICU and dialysis. Then, a systematic review of all potential quality markers was done to see what options for measures were possible. Next, following a meeting of leaders of dialysis in the ICU, the most important of these measures were ranked to decide which ones could be used in monitoring CRRT for patients.
Prospective, multi-center study to assess safety and performance of the Edwards EVOQUE Tricuspid Valve Replacement System
This study evaluates whether participating in a home-based exercise program leads to lower levels of complication rates and patient-reported disability after surgery. Half of the participants will be randomized into the exercise group, while the other half will be randomized into the control group.
The purpose of this study is to compare the daily pain level scores for patients taking opioids alone for pain relief, compared with those treated by multimodal analgesia with three medications: pregabalin, naproxen, and acetaminophen, with the ability to switch over to opioid medications if needed. In addition to pain level scores, this study will compare opioid use (length of time and doses taken), quality of life, admissions to hospital, feeding tube requirements, weight loss, and treatment interruptions between these two analgesic regimens.
The goal of this randomized phase II study is a formal comparison of radiotherapy versus trans-oral surgery as the primary treatment of HPV-negative patients with early-stage oropharyngeal carcinoma.
This is a Prospective, Open-label, Multicenter, and Non-randomized Clinical Study. The main purpose of this study is to establish the efficacy and safety of a medical device system, SETA LATECBA Stent Graft, intended for the treatment of EVAR of pararenal AAA (patients with complex anatomy, not eligible for other surgical procedure).Other objective is to evaluate the technical performance of the device SETA LATECBA Stent Graft.
Falls in daily life are one of the most significant complications for people with stroke. Fall rates are particularly high soon after discharge from stroke rehabilitation. A new type of balance training, called reactive balance training (RBT), can reduce fall rates after discharge from stroke rehabilitation. In our previous study, RBT was implemented as part of routine care, and as a result, the dose of training was different for each participant; participants completed between one and twelve 30-minute sessions of RBT. Previous research in healthy older adults suggests that a single session of RBT is enough to lead to lasting changes in reactive balance control and reduce fall rates in daily life. It is not clear if the same is true for people with stroke, who have more severe impairments and might need a higher dose of training to achieve the same benefits. The overall goal of this work is to determine the optimal dose of reactive balance training for people with stroke who are attending rehabilitation. This pilot study will determine the feasibility of a clinical trial to address this larger goal. People with sub-acute stroke will be randomly assigned to one of three groups: 1 session, 3 sessions, or 6 sessions of RBT. Each session will be 45 minutes long, and will occur as part of participants' routine out-patient rehabilitation. We will use our experiences with this pilot study to help design a larger study. Specifically, we will use this pilot study to answer the following questions: 1) what is the optimal sample size; 2) how long will it take to reach this sample size; 3) what outcome measures should be used; 4) how feasible is it to prescribe a specific dose of RBT to people with sub-acute stroke; and 5) what two intervention groups should be included in the larger trial?
Acute otitis media (AOM) is the most common indication for antibiotics for Canadian paediatric patients. As the gatekeepers of safe and effective prescription pharmacotherapy, community pharmacists are well positioned to influence and optimize antibiotic use. The purpose of this project is to develop, implement, and evaluate an antimicrobial stewardship program in the community pharmacy setting that aims to optimize antibiotic use for AOM. This nonrandomized pre-post study includes children aged 6 months to 12 years presenting with an antibiotic prescription for AOM at two community pharmacies in Toronto, Ontario. Participants are excluded if they exhibit signs/symptoms of mastoiditis, have an additional indication for systemic antibiotics, or parents/guardians cannot consent in English. The multifaceted AMS intervention includes pharmacist education, a clinical decision support tool, a parent/guardian questionnaire, and individualized monthly audit and feedback with each pharmacist. Prescriptions are reviewed and adapted by the pharmacist to optimize congruence with 2016 Canadian Paediatric Society AOM guidelines. The primary outcome is the percentage change in guideline congruence attributable to pharmacist intervention. This study will provide insight into the opportunities and barriers of developing large-scale antimicrobial stewardship programs for community pharmacies.
