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.
The purpose of this study is to evaluate the frequency of chronic breast pain about 8 years after the delivery of the radiation treatment, and to compare the frequency between subjects that received breast Intensity-Modulated Radiation Therapy (IMRT) and those that received standard wedge radiotherapy. The cosmetic result, meaning how similar is the treated breast compared to the non-treated breast, will be assessed. Also, the occurrence of delayed radiation treatment side effects including tiny red vessels in the skin, breast indurations (hardening of the skin), skin discoloration, oedema (swelling of the breast), and skin dryness will be captured.
The purpose of this study is to examine the effects of a combination of "Botulinum Toxin (BT) and Upper Limb (UL) rehabilitation" compared to "BT only" on UL motor function in adults with spasticity after stroke using a pre-post design. The research question is whether combination of BT and UL rehabilitation compared to BT only is more effective in improving the UL function, range of motion and pain.
Lipoprotein lipase deficiency (LPLD) is an autosomal recessive inherited condition caused by homozygosity or compound heterozygosity for mutations within the LPL gene. LPLD results in subjects presenting with fasting plasma triglyceride (TG) levels of > 10 mmol/l. LPLD typically presents in infancy or childhood with usual complaints of severe abdominal pain, repetitive colicky pains and repeated episodes of acute pancreatitis The most severe clinical complication associated with LPLD is acute pancreatitis. Pancreatitis in an LPLD subject often leads to prolonged hospital admissions (sometimes up to weeks). Subjects who survive repeated episodes of acute pancreatitis may develop chronic pancreatitis, ultimately resulting in endocrine and exocrine pancreatic insufficiency. The clinical manifestations of acute pancreatitis episodes related to LPLD are largely indistinguishable from acute pancreatitis due to other causes. However, collection of data relating to hospital admissions, laboratory test results, scan images and adverse events occurring concomitantly to the acute pancreatic episode should allow elimination of other causes of pancreatitis (e.g gallstones etc) and ultimately allow confirmation of LPLD-related acute pancreatitis. Characterization of the presentation of symptoms which occur around the time of known episodes of LPLD-related acute pancreatitis should also permit identification of episodes of acute pancreatitis which have previously been considered as unrelated or even unrecognized. The objective of the study is to re-assess and re-confirm data previously recorded about the incidence and severity of acute abdominal "pancreatitis" episodes in LPLD subjects previously enrolled on AMT clinical studies. To assess and document the presentation of acute abdominal episodes that occur around known episodes of pancreatitis and to permit the identification of possible new previously unrecorded episodes of pancreatitis based upon predefined diagnostic criteria. The objective is to recruit the 27 subjects previously enrolled in the above mentioned clinical studies.
Aesthetic evaluation of two piece 3mm implants for single tooth replacement of maxillary laterals and mandibular incisors
Individuals with a past diagnosis of severe combined immune deficiency (including many cases of "leaky SCID", Omenn syndrome, and reticular dysgenesis) who have undergone blood and marrow transplant, gene therapy, or enzyme replacement in the past may be eligible for this study. The purpose of study is to look backwards at what has already been done in the. Over 800 patients with SCID are expected to be enrolled, making this one of the largest studies ever to describe outcomes for patients with SCID treated at many different hospitals around North America.
Myocarditis is an inflammatory heart disease primarily of viral origin that can lead to heart failure and death. Despite an unfavorable long-term outcome and mortality rate as high as 50%, classification, diagnosis, and treatment of myocarditis remains controversial. The gold standard for clinical diagnosis is direct sampling of the heart muscle, which often misses the infected area and thus reliability of the test is questionable. While the cause and clinical presentation of myocarditis are often unclear, inflammation of the heart muscle can be clearly imaged by Cardiovascular Magnetic Resonance Imaging (CMR). Due to recent international consensus on CMR protocol for myocarditis and the unique ability of CMR to visualize cardiac structure, function, and characterize tissue, CMR has become the primary tool for clinical assessment. This study aims to test the accuracy of CMR in the diagnosis of myocarditis and to validate whether CMR acquired in an early stage of myocarditis can provide incremental prognostic information. In order to effectively gather relevant clinical data, an online, multi-centre international registry will be established across twenty different medical institutions. Hypotheses: 1. CMR accurately detects active myocardial inflammation in patients with myocarditis 2. CMR acquired in an early clinical stage of myocarditis provides incremental prognostic information superior to standard clinical diagnostic tools.
The primary objective of this trial is to assess whether Rhodiola rosea improves fatigue when compared to placebo in nurses involved in shift work.
The purpose of this study is to determine whether rapid eye movements called saccades are impaired in glaucoma, a neurodegenerative disease of visual pathways.
The objective of this study is to assess the safety and tolerability of 10, 10, 20 milligrams per kilogram (mg/kg) ataluren in participants with nmDBMD who had prior exposure to ataluren in a PTC sponsored clinical trial or treatment plan, and siblings of those participants (provided those participants have completed the placebo-controlled portion of the trial). The treatment will continue under this protocol until consent withdrawal by participants, withdrawal due to worsen condition after initiating ataluren treatment, withdrawal by investigator, withdrawal due to participant unable to tolerate ataluren, participant is eligible to participate in another ataluren nmDBMD clinical trial program initiated by sponsor, study is discontinued by the relevant regulatory authority and/or sponsor, or until ataluren becomes commercially available.
The following study is designed in order to effectively collaborate and coordinate information amongst colleagues to advance knowledge on information related to older drivers. Candrive is dedicated to improving the safety and quality of life of older drivers. The major objective is to develop a valid, easy to use in office screening tool that will help clinicians identify older drivers who need further assessment of their driving. Over the course of the study, the goal will be to provide enough data to establish findings relating to knowledge generation, translation of research into action, training and sustainability. It is our hope that the research process will translate to help increase the knowledge of public policy makers, clinicians and the general public. A 5 year study will create an opportunity to document the natural course of an older adult's driving patterns up until driving cessation. This will not only provide data for road safety but also help understand the psychosocial factors leading to driving cessation. The data relating to psychosocial factors may also lead the way in establishing ways of extending the safe driving period for older adults. The investigators hypothesize that the knowledge derived from this interdisciplinary research will be used by transportation policy makers, clinicians, and general public to improve safety and quality of life for older drivers.
