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.
As the dural puncture epidural (DPE) is increasing in popularity for labor analgesia, it is important to understand how it impacts outcomes in parturients. Prior studies have found epidural catheters placed via the combined-spinal epidural technique have greater success at surgical conversion for cesarean delivery than catheters placed via traditional techniques. The investigators aim to determine if epidural catheters placed by a DPE technique will also have an increased successful conversion for surgical anesthesia by conducting a retrospective review of all CD during the study period. If an association is found, this could be another benefit of DPE for labor analgesia.
Dysphagia (swallowing impairment) is a serious health condition seen in many age-related disease and injury processes. Although videofluoroscopy (VF) is an international "gold standard" dysphagia diagnostic exam, there is a paucity of available normative physiologic VF reference values in healthy adults across the age span to guide interpretation of these examinations. In this project, the investigators will extend previous work on the quantitative measurement of swallowing physiology from VF examinations to establish reference values for swallowing in healthy adults, and to identify clinical decision point values for differentiating healthy swallowing across the age span from disordered swallowing in several high-risk clinical populations to study dysphagia.
This is a 2-part (phase 2b/3) prospective, interventional, multicenter, randomized, double blind, placebo controlled study. Part 1 (phase 2b) is a dose-finding study for CSL300 vs placebo. Part 2 (phase 3) aims to assess the efficacy of CSL300 on CV outcomes and safety in subjects with ASCVD or diabetes mellitus and evidence of systemic inflammation who are undergoing maintenance dialysis.
Non-ambulatory children with cerebral palsy (CP) and similar childhood-onset neuromotor conditions face many challenges to fulsome participation in everyday life. Recent initial phase research suggests that physiotherapy paired with use of robotic exoskeletons, such as the Trexo exoskeleton ("The Trexo"; Trexo Robotics, Canada) provides a novel opportunity for children with severe mobility challenges to experience active walking that is individualized to their movement potential (guiding and powering leg movements) and upright support needs. This before-and-after study will assess the first-time experience of 10 non-ambulatory children (ages 4-7) using the Trexo for 6 weeks of twice weekly physiotherapy sessions, and evaluate associated brain, muscle and functional outcomes including accomplishment of individualized goals. To study clinical utility, we will simultaneously capture physiotherapists' (PTs) and PT assistants' (PTAs) training/learning/user experiences with the Trexo's first time use within our center's out-patient program and on-site affiliated school. This project will contribute evidence-based knowledge to guide clinical decisions about introduction of the Trexo within pediatric rehabilitation settings (target demographic, potential goals, integration into physiotherapy) and be a foundation for a progressive program of multi-centre research. Overall, we hope that this research will lead to better opportunities for children's meaningful participation within the community, including family and peers.
Ehlers-Danlos Syndrome (EDS) is a disease that weakens the connective tissues (i.e. tendons and ligaments) in the human body. EDS can make the joints loose and alter skin and wound healing. It can also weaken blood vessels and organs. Many EDS patients are referred for investigation of bleeding symptoms. Although most patients will have mild symptoms such as bruising, many will experience significant bleeding that can be life-threatening. The physiological reason behind this has not been identified and therefore, treating this is challenging. In addition, patients with EDS frequently require major surgery due to complications from their connective tissue disease. These surgery carries a significant risk of catastrophic bleeding which is further magnified in this group of patients. The specific reason of clinical bleeding in patients with EDS is likely multifactorial, including skin and blood vessel fragility leading to increased bruising and poor wound healing, coagulopathies related to factor deficiency, acquired vonWillebrand disease (VWD), and notable platelet dysfunction. Despite compelling preliminary evidence, there is limited data on the diagnosis and management of platelet dysfunction in EDS patients. Therefore, in this study we will characterize hemostasis, the medical term which refers to the process of stopping blood flow, across the three most common subtypes of EDS.we will also determine the burden of illness of pathologic bleeding in patients with Ehlers-Danlos Syndrome (EDS) using validated patient reported tools.
Establishing the diagnosis of Ehlers Danlos Syndromes (EDS)/generalized hypermobility spectrum disorders (G-HSD) is often problematic for patients. The absence of a precise unifying diagnosis in patients results in a significant emotional burden on the patient and caregivers, not to mention the hidden costs, including multiple recurring visits to several medical specialists and associated social and economic costs. To date, while collagen ultra-scale morphological heterogeneity has been used to comment on an EDS diagnosis, the mechanical properties of the collagen remain mostly unexplored. From a biophysical point of view, collagen affected with hEDS can be described as biomechanically deficient. In the case of EDS, the skin's abnormal elasticity can be directly related to the organization of the collagen network within the dermis. Quantitative Nanohistology (QNH) is a newer method to evaluate both the structural and mechanical properties of collagen in-situ histological sections. Therefore, the aim of this study is to define histo-biophysical markers of two most common types of EDS i.e. classical EDS (cEDS) & hypermobile EDS (hEDS) at the single collagen fibrils level and matrix and to further explore the origin of collagen fibril properties deficiency in hEDS and cEDS.
An Open-label Extension Study to Evaluate Long-term Efficacy and Safety of Odevixibat (A4250) in Children with Biliary Atresia
This study aims to test if making changes to diet can affect the pelvic pain associated with endometriosis. One group will follow a Mediterranean diet for 12 weeks while the control group will continue with their current diet. We will be looking at the feasibility of a larger-scale trial as well as self-reported quality of life and self-reported pain using standardized questionnaires, that have previously been used and validated, and assessing how this diet affects biomarkers associated with endometriosis and inflammation. Further, we will test how this change in diet affects the gut microbe flora.
Ehlers Danlos Syndrome (EDS) is a heterogenous group of genetic disorders with 13 identified subtypes. Hypermobile EDS (hEDS), although the most common subtype of EDS, does not yet have an identified genetic mutation for diagnostic confirmation. Generalized joint hypermobility (GJH) is one of the hallmark features of hEDS. The scoring system used in measurement of GJH was described by Beighton. The Beighton score is calculated using a dichotomous scoring system to assess the extensibility of nine joints. Each joint is scored as either hypermobile (score = 1) or not hypermobile (score = 0). The total score (Beighton score) can vary between a minimum of 0 and a maximum of 9, with higher scores indicating greater joint laxity. While there is moderate validity and inter-rater variability in using the Beighton score, there continue to be several challenges with its widespread and consistent application by clinicians. Some of the barriers reported in the literature include: i) In open, non-standardized systems there can be significant variation in the method to perform these joint extensibility tests including assessing baseline measurements, ii) Determining consistent and standard measurement tools/methodology e.g. goniometer use can vary widely iii) Assessing the reliability of the cut off values and, iv) Performing full assessment prior to informing patients of possible classification of GJH positivity (low specificity and low positive predictive). Inappropriate implementation of tests to assess GJH results in inaccurate identification of GJH and potentially unintended negative consequences of making the wrong diagnosis of EDS. The objective of this study is to create a more robust and valid method of joint mobility measurement and reduce error in the screening of EDS through use of a smartphone-based machine learning application systems for measurement of joint extensibility. The project will: i) Create a smart-phone enabled visual imaging app to assess the measurement of joint extensibility, ii) Assess the feasibility of using the smart-phone app in a clinical setting to screen potential EDS patients, iii) Determine the validity of the application in comparison to in person clinical assessment in a tertiary care academic EDS program. If successful, the smart-phone application could help standardize the care of potential EDS patients in an efficient and cost-effective manner.
The purpose of the current study is to measure oxygenation in the PFC using fNIRS in a sample of older adults with hearing loss. Adults with hearing loss will be asked to repeat the final word from low-context sentences in noise at two SNRs; a hard SNR (individually-measured SNR-50), and an easy SNR (SNR-50 + 10 dB) both without and with hearing aids set to a directional mode. The procedure will be a within-subject repeated measures. Stimuli will be randomized.
