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 provide evidence for the empirical and clinical utility of a novel pain relief measure, the IPR, dimensions of which will be validated against the present gold standards for pain measurement.
Video assisted thoracoscopic surgery (VATS) is a minimally invasive surgery to remove lesions from the thoracic cavity. It is associated with moderate pain which can lead to pulmonary complications after surgery. The Enhanced Recovery After Surgery (ERAS) and the European Society of Thoracic Surgeons recommended a multimodal analgesia approach to manage pain after VATS. Erector spinae block (ESB) is a popular analgesic block due to its ease of performance and wide coverage. It has been shown to be effective in randomized control trials. Recently, case reports on bi-level ESB are emerging, suggesting more effective analgesia compared to single level ESB. As there is no available data, the investigators are interested in conducting a randomized pilot study, comparing bi-level to single level ESB to gather baseline data for sample size calculation for a formal randomized trial.
This is an assessor-blinded randomized feasibility trial evaluating a new dynamic bar for foot abduction bracing for clubfoot treatment. Eligible patients must have a well-corrected idiopathic clubfoot (Pirani Score ≤ 0.5) and be in the minimum 12 hours per day bracing stage of the Ponseti clubfoot treatment protocol. The overall study period will be 90 days in length. For the first 30 days, the experimental cohort will wear the new Dynamic Bar (DB) with standard ankle-foot orthoses (boots) and the control cohort will continue wearing the standard Straight Bar (SB). After this 30-day period, the experimental cohort will return to wearing their standard SB. All patients will be evaluated on Day 0, Day 7, Day 30, and Day 90 of the study period to monitor for recurrence of the clubfoot deformity, complications of brace wearing, to submit brace wear logs, and to complete parent-reported questionnaires regarding their perceptions of the Foot Abduction Brace (FAB) and their child's comfort. A minimum of 10 patients per arm will be recruited. A temperature sensor will be added in each participant's boots during the 90-day study period to objectively measure time of brace wear. It is hypothesized that when patients are wearing the DB they will experience higher brace tolerance defined as increased wear time of the brace as measured by the temperature sensors, and higher comfort levels as reported by parents, without an increase in clubfoot deformity recurrence compared to the SB.
The study looks at the comparative effects of food products made with pea, lentil, and oat flour of various particle sizes on postprandial glycemic response, appetite and food intake, and amino acid release in healthy adults.
Anatomical-based ultrasound imaging has been one of the most rapidly advancing innovations in the field of regional anesthesia in recent years. The proper performance of ultrasound guided regional anesthesia (UGRA) is a useful competency for any anesthesiologist. However, there are some obstacles in regional anesthesia education for trainees. The increasing availability of UGRA related online information may have an important educational value for trainees and consultants. The objective of this study is to assess the impact of using educational material from The New York School of Regional Anesthesia (NYSORA) and Ultrasound for Regional Anesthesia (USRA) websites on image acquisition and anatomical interpretation learning process of medical students performing ultrasound guided supraclavicular brachial plexus block. We hypothesize that the use of those online educational materials will give medical students non inferior ability and knowledge for image acquisition and anatomical interpretation of ultrasound image for supraclavicular brachial plexus block, when compared to conventional in person teaching.
PANTHER-GI Pilot Study will assess the feasibility of a full-scale multicentre cohort management study evaluating the safety of a standardized strategy for resuming direct oral anticoagulants (DOACs) after major DOAC-related gastrointestinal (GI) bleeding among patients at moderate to high risk of re-bleeding and thrombosis. A parallel registry will assess whether eligible patients who are not enrolled in the PANTHER-GI Pilot Study are systematically different than enrolled patients and to explore barriers to enrolment.
Viral respiratory tract infections (VRTI) are among the most common human illnesses, impacting billions globally. There is an unmet need to identify novel ways to detect, treat and prevent their spread. New wearable devices could address this need, using special biosensors worn by patients. This is a single centre, controlled, before and after, longitudinal, clinical trial. Participants will receive FluMist, a live attenuated influenza vaccine, which will act as a proxy to a viral respiratory tract infection and create a very minor response to the immune system. Vital signs and activity levels will be monitored continuously using wearable biosensors for 7 days prior to and 7 days following, along with symptom tracking and blood tests to measure immune responses. Artificial intelligence (AI) and machine learning (ML) algorithms will be used to analyse the data. AI and ML will identify subtle changes in vital signs and activity levels from the immune response to respiratory viruses. These data will help develop future methods to address important public health questions related to respiratory virus detection, containment and management. The purpose of this study is to explore whether wearable sensors can detect, track the progress and recovery from viral respiratory tract infection.
This is a Phase 2, randomized, placebo-controlled crossover trial to assess the safety and efficacy of NB-001 in children and adolescents with 22q11DS that manifest commonly associated neuropsychiatric conditions.
The delivery of timely and appropriate care is crucial for patients with heart attacks. Blocked arteries need immediate intervention to restore blood flow. However, the intervention to open the artery is only available in large, regional hospitals. There are only 18 such hospitals across Ontario. Patients with heart attacks in smaller hospitals, where the majority of patients present, require transfer for specialized services. The smartphone application being evaluated in this study is meant to help with communication between doctors to arrange transfer of such patients. The current model for communication is based on fax machines or non-secure text messages. Additionally, these are not easily accessible for most physicians, so decisions to transfer patients may be based on incomplete information. Unnecessary transfer, treatments, and procedures expose patients and healthcare providers to undue risk. Smartphone technology is well integrated into clinical practice and widely accessible. The proposed solution being tested is secure and leverages the accessibility of smartphones. Emergency physicians can use this to quickly, securely, and accurately transmit information ensuring faster and appropriate decision making for transfers.
This study is designed to determine the minimal effective oxytocin maintenance infusion required in labouring women undergoing cesarean delivery to achieve the best effect. Oxytocin is a drug that is routinely used to help the uterus to contract and keep it contracted after delivery. Consequently, it will help to reduce blood loss after delivery. In order to determine the minimal effective dose, the investigators will conduct a dose-finding study. The first patient will receive a set oxytocin infusion. The next patient's infusion dose of oxytocin, will either increase or decrease, depending on how the previous patient responds in terms of uterine tone. If the response is satisfactory with the infusion dose used, the next patient will either receive the same infusion dose or it will be decreased depending on a probability of 1:9. If the response is not satisfactory, then the infusion dose will increase for the next patient. The dose for each patient will be determined based on the results of the uterine contraction of the previous patient. The investigators hypothesize that the ED90 of the oxytocin infusion rate to maintain adequate uterine tone in labouring women with induced or augmented labour undergoing cesarean delivery, following an initial effective bolus dose, would be lower than 0.74 IU/min (44 IU/h), which was found as the ED90 in a previous study, without an initial bolus dose prior to the infusion.
