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.
Body composition analysis is frequently used in both clinical and research settings for evaluation of nutritional status and follow-up. Bioelectrical impedance analysis (BIA) is one method that has been extensively used to measure body composition. To ensure the reliability of BIA results, several recommendations are proposed in the literature. One of them is to avoid coffee and caffeine prior the test. This instruction is primarily based on the potential diuretic effects of caffeine however few studies evaluated the impact of coffee on fluid balance. Research participants usually have several commitments, especially those enrolled in clinical trials. Simplified and evidence-based instructions can avoid unnecessary restrictions and lead to better participant compliance.
Our aim, in this study, is to elucidate the optimal dosing range (ED50 and ED95) of bolus remifentanil in order to counter the painful stimuli resulting from direct laryngoscopy and tracheal intubation by using the NOL index. In order to maximize the clinical relevance of our findings, induction of general anesthesia will be done with standard medications and doses and laryngoscopy will be done with the Macintosh laryngoscope, the most common tool used for intubation in the operating room
Emotional eating is a behaviour that has been linked to weight concerns, mental health concerns, and disordered eating. Effective interventions have been developed to treat emotional eating, however these exist solely in the context of promoting weight loss. Emotional eating is not exclusive to those who struggle with weight and thus interventions are needed that target those who engage in emotional eating regardless of their weight status. The present study aims to do so through the implementation of a one day Acceptance and Commitment Therapy (ACT) workshop for emotional eaters.
Women with mood disorders are vulnerable to the negative consequences associated with obesity, and face considerable challenges with adherence to behavioral weight management interventions. Strategies are needed to support the psychological well-being of this population, and improve adherence to weight-related treatment. The goal of this preliminary study is to determine the acceptability of a group-based compassion-focused psychoeducational intervention among women with mood disorders who are attending a behavioral weight management program.
This pilot study uses a randomized controlled trial design to introduce an educational session for breast reconstruction patients. Participants will be randomly assigned to the (1) control group or the (2) experimental group. The control group will receive the current standard educational information from the surgeon along with an information package, while participants in the experimental group will also receive an additional education session before their operation about what to expect during their reconstructive journey. Satisfaction with care, anxiety about the procedure and recovery, and health related quality of life will be measured in all patients using established questionnaires. Additionally, feasibility outcomes will be reported and the results of this study will be used to demonstrate whether a larger version of this study can be successfully completed.
Square knots are the gold standard for hand-tied surgical knots; however, they are difficult to reproduce in deep body cavities and can inadvertently result in slipped knots. The investigators have shown in previous work that the reversing half-hitch alternating post (RHAP) surgical knot is a non-inferior alternative to the square surgical knot based on its tensile strength and performance in limited working spaces. Prior to introducing RHAP knot in routine surgical practice, it is important to objectively demonstrate similar physical characteristics of anastomosis created using RHAP and standard square knots. This study aims to compare the burst pressure of cadaveric porcine small bowel anastomosis constructed using RHAP and standard square knots on a flat surface and in a simulated deep body cavity. The investigators are conducting a prospective randomized controlled study of novice medical students allocated to proficiency-based training in RHAP and square surgical knots. Knot tying proficiency will be assessed using a knot-tying checklist. Number of repetitions and time required to achieve proficiency will be tracked for each group. Once proficiency has been achieved by participants in RHAP and square knots group, each participant will perform two-hand sewn small bowel anastomosis using cadaveric porcine small bowel. One anastomosis will be performed on a flat surface and the other will be formed in a simulated deep body cavity. Burst pressure of the anastomoses will be tested using a column of water, and results will be compared between groups. Simple descriptive statistics will be performed for both groups. Between group comparisons of knot-tying proficiency and burst pressure will be performed using t-test. Learning curves within each group will be analyzed using paired 1-way ANOVA. SPSS Statistics (v. 21, IBM, New York, USA) will be used for all statistical analysis, with significance set to p<0.05. The investigators hypothesize that burst pressure of cadaveric porcine small bowel anastomosis will be equivalent for anastomosis constructed using RHAP and standard square knots. The results of this study will provide further validity evidence in support of RHAP as suitable alternative to the square surgical knots.
This study will collect data on bleeds and data related to quality of life in people with severe congenital (a disease existing from birth) haemophilia A and B, with or without inhibitors. The aim for the study is to look at the number of bleeds when on usual treatment for haemophilia. Participants will be asked to keep an electronic diary to track the number of bleeds and the treatment of their bleeds. Participants will be asked to wear an activity tracker on their wrist to capture their level of activity every day for up to 12 weeks. While taking part in this study, participants will keep getting their usual treatment as given to them by their doctor. All study visits at the clinic are done in the same way as the participants are used to. In the time between the participants' visits to the clinic, the study staff at the clinic may call or email the participant. The study will last for about 2½ years.
This study is an open-label, prospective, single-centre, randomized controlled trial, containing both a quantitative and a qualitative component and using a mixed-methods design. The study evaluates the impact of Cloud Dx kit, a device that can allows patients to monitor and manage Chronic Obstructive Pulmonary Disease (COPD) at their home. The study evaluates whether using Cloud Dx improves patients' COPD symptoms, ability to manage COPD, and quality of life. It is anticipated that there will be 123 participants enrolled in this study across two experimental arms and one control arm. Participants will be in the study for 6 months and the study will run for 1 year a Markham-Stouffville Hospital. The primary outcome is the participants' self-management and activation which will be measured using The Partners in Health (PIH) scale, a validated scale measuring the current status of self-management, with items on knowledge of the condition and skills to monitor and respond to symptoms.
This study evaluates the diagnostic performance and safety of 18F-DCFPyL (PyL) PET/CT imaging in patients with suspected recurrence of prostate cancer who have negative or equivocal findings on conventional imaging.
The objective of this study is to evaluate the efficacy, safety and tolerability of cariprazine as an adjunctive treatment to antidepressant therapy (ADT) in patients with MDD who have had an inadequate response to antidepressants alone.
