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 prospective randomized clinical trial aims to evaluate the new Optivista system compared to the iScan for his optical diagnosis and interval agreement monitoring with pathology. The Participants will be randomized to be diagnosed by either Optivista or Pentax iScan, and all polyps detected during the procedure, their size, location and morphology will be recorded according to the Paris classification after which all polyps will be resected per standard practices and sent for histopathologic evaluation. Further optical assessments will be performed for all polyps of 1-10 mm in size (WASP, NICE, SANO and SIMPLE classification) after with an analysis of comparison between optical diagnosis and pathology results will be performed.
As anesthesia is often needed for childhood surgery and procedures, researchers have examined the potential effects of anesthesia on neurodevelopment. There are few studies that have examined the effect of anesthesia on neurodevelopment in children with confirmed diagnoses of ASD, and the results of these studies are mixed. Children with neurodevelopmental disorders can have age-dependent variations in brain anatomy, function, and connectivity, which may alter their sensitivity to the potential neurotoxic effects of anesthetic and sedative drugs. Given the potential adverse neurodevelopmental effects of anesthesia on typically developing children, it is important to examine if anesthesia exposure can worsen the clinical course of ASD.
Despite their efficacy at controlling joint inflammation, current treatments of rheumatoid arthritis (RA) leave up to 40% of patients into non-remission. Non-remission is most frequently due to persistently negative self-reported global impact of RA, and not to remaining swollen joints or elevated levels of acute phase reactants. In a cohort of recent-onset RA patients diagnosed early and treated to remission (Sherbrooke Early Undifferentiated PolyArthritis (EUPA) cohort), treatment of active disease rapidly led to reduced depressive symptoms in most, but 20% still expressed elevated depressive symptoms (using the CES-D screening tool) after a mean of 7 months. Elevated CES-D scores at this early time strongly predicted never reaching remission over the following 4 years. Elevated CES-D scores were strongly correlated with increased levels of patient-related outcomes (PROs such as fatigue, pain, sleep quality, stiffness and functional limitation), but not with joint or systemic inflammation. In fact, 80% of patients expressing depressive symptoms had controlled joint disease at the same visit. The investigators propose that addressing depressive symptoms will improve RA patients' symptoms and quality of life. In clinical practice, the best indicator of depressive symptoms is the presence of a disconnect between the Patient's (Pt-VAS) and the Physician's (MD-VAS) evaluation of disease activity in patients without objective signs of inflammation. This pilot study will explore the feasibility and acceptability of testing MBSR in these patients. It will assess over 6 months the changes in depressive symptoms and PROs both in controls and MBSR-treated patients. If positive, the investigators plan to complete a multicenter 6-month Randomized Clinical trial (RCT) (with a 2 year follow up) to formally address the risks/benefits of group MBSR interventions in RA patients with controlled inflammatory disease but positive disconnect between Pt-VAS and MD-VAS.
It has been established that greater amounts of vigorous intensity physical activity lead to improved health outcomes. Interestingly, the response of biologically active substances, called myokines, differs according to exercise intensity. As such, the current study aims to compare the difference in the response to irisin according to different exercise intensities in both normal weight subjects and individuals living with obesity. This study will compare continuous moderate intensity physical activity to high intensity physical activity against a control condition. Furthermore, this study will determine whether differences in exercise intensity are associated with better insulin sensitivity.

It is well documented that severe pain is more common in older adults than it is younger persons. Of concern, older adults may not have access to traditional face-to-face self-management programs, which are recognized to be valuable in chronic pain management. Access to effective self-management approaches is particularly important for older adults who may have mobility limitations or live in remote areas, or have difficulty accessing health care services. The development of effective pain self-management programs for older adults who cannot access traditional psychological interventions is of significant importance. Internet self-management programs have the potential to address pain undermanagement. As technology advances, the digital divide between the older and younger demographic continues to progress. Given the known difficulties with treatment access, the purpose of this study is to explore the efficacy and acceptability of a remotely-delivered chronic pain self-management program tailored to older adults, the Pain Course, when delivered in online and workbook formats. The program was previously shown to be effective among younger persons but has not been tested with older adults.
This Phase 1/1b, open-label, first-in-human, monotherapy study will be conducted in 2 parts. Part A will consist of the SRF231 monotherapy dose-escalation portion of the study, and will enroll up to 48 patients with advanced solid tumors and hematological cancers. Part B will include monotherapy expansion cohorts in advanced solid and hematologic cancers to further examine SRF231 as monotherapy (100 patients total).
The primary objective of this study was to compare the two alternate primary endpoints of radiographic progression-free survival (rPFS) and overall survival (OS) in patients with progressive prostate-specific membrane antigen (PSMA)-positive metastatic castration-resistant prostate cancer (mCRPC) who received 177Lu-PSMA-617 in addition to best supportive/best standard of care (BSC/BSoC) versus patients treated with best supportive/best standard of care alone.
Transcranial magnetic stimulation (rTMS) is an investigational and therapeutic modality that impacts the connection strength between neurons by delivering patterned energy. In response to this patterned energy neurons fire and adapt by changing their connection strengths. This change in connection strengths is believed to be the underlying mechanism whereby this intervention has therapeutic benefit for this intervention in conditions such as depression. The purpose of this study is to test a means of enhancing the effect of rTMS using a medication (cycloserine) that has been shown to augment and stabilize activity dependent neuronal changes. The investigators wish to use the motor system, where the associated muscle response to brain stimulation can be measured, to probe activity dependent changes in connection strength between neurons.
