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 objectives of this study are to confirm the safety and efficacy of FCH-PET/CT and to establish our ability to reproduce results from the literature using FCH-PET/CT as a diagnostic and decision making tool in the management in two predefined groups of prostate cancer patients, specifically, biochemical recurrence and high risk staging. The primary endpoints of the study are the incidence of adverse events (AE) in the study population up to 24 hours following the scan, and the sensitivity and specificity of FCH-PET/CT vs CT on a per-patient and per-lesion basis.
The main purpose of this study is to determine the effect of consumption of purple wheat anthocyanin-rich products for eight weeks by human participants with an elevated level of chronic inflammation, on oxidative stress and inflammatory responses as measured by select plasma biomarkers.
Positron emission tomography/computed tomography (PET/CT) is an advanced nuclear medicine scan. This technology allows precise and early cancer to be visualized and measured on whole body images. Patients with Neuro-Endocrine tumors (NETs), require specialized molecular imaging to stage, re-stage and assess eligibility and response to therapy. 68Ga-DOTATATE is a nuclear medicine imaging agent that is not yet approved by Health Canada but used extensively throughout the world. The Ki-67 index, a marker of cell proliferation in NETs, is one of the most important prognostic factors in this disease. The objective of this study is to evaluate if the maximal standard uptake value (SUVmax) on PET/CT in NETs inversely correlates with Ki-67 score on initial biopsy. If this hypothesized correlation between SUV and Ki-67 score is reproduced, then DOTATATE would serve as a non-invasive method to assess cellular proliferation and therefore prognosis of these patients.
In this comparative bioavailability and in vivo skin adhesion study, the impact of minor changes in qualitative composition of polyiso-Butylenes (PIB) from a different supplier and change of the manufacturing line of the micro porous membrane will be tested.
To evaluate the safety and performance of the HLT System in patients with severe aortic stenosis who present at high risk for aortic valve replacement surgery.
Partially assisted mechanical ventilation is ideally titrated to maintain adequate inspiratory muscle activity (i.e. preventing disuse atrophy) while avoiding excessive (i.e. fatiguing) inspiratory loads. The advent of ventilator modes enabling flow and pressure assistance in proportion to patient inspiratory effort (i.e. Proportional Assist Ventilation (PAV), Neurally-Adjusted Ventilator Assist (NAVA)) permit careful titration of ventilatory support to achieve desired levels of patient inspiratory effort. However, data on the acceptable range of values for inspiratory effort and respiratory muscle load-capacity balance during mechanical ventilation are currently very limited. Such data are critical to inform a physiologically sound evidence-based approach to titrating partially-assisted ventilatory support. This study is designed to ascertain a physiologically acceptable range of inspiratory effort in mechanically ventilated patients. The study protocol includes measurements of the respiratory system during spontaneous breathing as well as evaluating the diaphragm in real-time with the use of ultrasonography. The experimental design outlined in the present study is predicated on the assumption that the range of values for inspiratory effort and load-capacity balance observed in patients who are successfully weaned from mechanical ventilation represent the safe and appropriate range of target values.
This study will be an 8-week open-label pilot study examining subjective and objective changes in mood, anxiety, cognition, and sleep before and after the introduction of a probiotic supplement containing Lactobacillus helveticus and Bifidobacterium longum in 10 treatment-naïve participants diagnosed with major depressive disorder (MDD). In order to examine the full composition of the micro biome, the investigators will also be collecting and analyzing fecal samples as well as blood samples to examine changes in plasma levels of inflammatory markers, 5-HT, and tryptophan in order to look at possible underlying mechanisms of any changes seen.
Rotator cuff tendinopathy (RCT) is the most frequent cause of shoulder pain. RCT is frequently termed as impingement syndrome, based on the underlying mechanism in which the subacromial space soft tissues (subacromial bursa, rotator cuff tendons and long head of the biceps tendon) get encroached under the coracoacromial arch when the arm is elevated. RCT contributes in the decrease in quality of life and function, and in inducing work incapacities and sleep disorders. Exercises, as conservative management, were shown to be effective in increasing function and in decreasing pain related to RCT. However, the lack of studies comparing different types of exercises (i.e. concentric, eccentric, scapular strengthening, proprioceptive, coactivation) is reported by many systematic reviews. One type of exercise, coactivation strengthening, could be more efficient. Coactivation strengthening implies a recruitment of the pectoralis major and the latissimus dorsi while performing regular strengthening. When theses muscles are recruited, the medio-inferior orientation of their tendons creates a force vector that limits the superior translation of the humeral head, thus limits the subacromial narrowing. The aim of this study is to evaluate the efficacy of coactivation strengthening exercises in patient with RCT compared to regular strengthening exercises. Forty-two participants diagnosed with RCT by an orthopaedic surgeon following a standardized protocol will be randomised to either coactivation or regular strengthening exercises. Participants will perform a 6-week exercise protocols. Outcomes will be measured at baseline, and at three, six, 12, 18 and 24 weeks. The primary outcome is function assessed with the Disabilities of arm, shoulder and Hand (DASH) questionnaire. Secondary outcomes focus on pain (visual analog scale), quality of life (Western Ontario Rotator Cuff Index), impression of change (Patient Global Impression of Change), subacromial distance (ultrasonography) and muscular strength (manual dynamometer). Investigators expect that coactivation strengthening exercises will be more efficient over the short and long term. This trial will provide data to guide clinicians in the treatment of RCT to reduce recovery time and to bring patients back as quickly as possible to work or usual function.
It's well known that Spinal cord stimulation (SCS) changes the perception of chronic pain in the area stimulated by epidural electrodes. However, we don't know the effect of this type of stimulation on the perception of external sensations (temperature, touch, pressure, and vibration) and sharp pain. Quantitative sensory testing (QST) is used to quantify somatosensory phenotype. This QST battery tests different subtypes of nerve fibres (Aβ, Aδ and C) involved in the transduction of sensory information from the periphery to the spinal cord. The purpose of this study is to evaluate the effects of the SCS on sensory perceptions of patients with chronic pain (CRPS, FBSS). Sensorial perception tests will be carried out in accordance with a standardized procedure (Rolke et al. Pain, 2006). For non-implanted patients, an initial visit will be conducted before the operation. For all participants, two other visits will take place at least 6 months after the operation to perform the tests with and without stimulation.
The purpose of this prospective randomized controlled trial (RCT) is to evaluate the feasibility and usability of a commercial pedometer and web application in a case-managed home-based Cardiovascular disease prevention and rehabilitation program for French-speaking Canadians.
