This study will investigate the feasibility of using repetitive transcranial magnetic stimulation (rTMS) and a sensorimotor training task to treat symptoms of pain in patients with complex regional pain syndrome (CRPS). rTMS is a non-invasive technique that involves delivering magnetic pulses in rapid succession over the area of the brain that controls movement. The sensorimotor training task involves non-invasive nerve stimulation used to cue a participant to complete motor actions. The purpose of this study is to determine whether recruitment is feasible in this patient population and patients maintain adherence to the intervention. In addition, the investigators want to determine whether rTMS combined with sensorimotor training is an effective intervention to alleviate symptoms of pain in patients with CRPS. Read Less

Drivers aged 65+ depend on their car(s) to get to the places and see the people that are important to them. Losing a license in later life has been linked to higher rates of loneliness, depression, and even admission to long-term care; a fact that is particularly relevant when considering the impact of the COVID-19 pandemic. While drivers in this age group are among the safest on the road, they have one of the highest risks of collision when distance driven is considered and are more likely to be seriously injured or killed. Motor vehicle crashes and falls are the top causes of injury-related hospitalizations in seniors. Through a partnership with older adults, driving instructors, and health professionals, we developed the Refreshing Older Adult Driving Skills (ROADSkills) program. This program uses a Global Positioning System (GPS) device that can be placed in people's cars, which can track their real-world, everyday driving patterns, including speeding and hard braking, alongside video data of their behind-the-wheel behaviour. Using this data, a personalized video will be created using information captured by the device in the older driver's car. This study will determine if the older drivers who receive this video feedback perform better than those who do not receive such feedback. Because this is the first time a study will use this type of behavioural intervention, we are interested in hearing from older drivers about their experience of participating in the study. The findings will help us to design a larger, national study of the ROADSkills program in Canada. Read Less

The overarching goal of this research protocol is to acquire eye-tracking, cognitive, and disease-severity metrics in multiple sclerosis (MS) patients to further build up a database of MS patients and train a machine learning classifying algorithms to identify which eye-tracking metrics-or combination thereof-can serve as reliable markers of MS disease severity and cognitive status.

This study evaluates the therapeutic tolerability of the use of Cognitive Processing Therapy (CPT) with propranolol in participants with Posttraumatic Stress Disorder (PTSD) and Alcohol Use Disorder (AUD). The investigators are planning to perform an initial proof -of- concept randomized, placebo- controlled trial evaluating propranolol in participants with PTSD and AUD starting CPT for 12 weeks with three post-treatment follow ups at week-16, week-20, and week-24. Participants with current diagnosis of PTSD and AUD seeking treatment will be randomized to either a propranolol group (n=24) or placebo group (n=24) after enrollment. All participants will receive CPT for 12 weeks after randomization. Primary outcomes will be measured in both groups at the end of the study (week 12). Read Less

The brain is a highly active organ that requires a large blood flow to function properly. Normally, blood flow is tightly linked to the brain's energy demands. However, during surgery, anesthesia can affect this relationship in different ways. Some types of anesthesia can decrease blood flow to the brain, while others can increase it. Anesthesiologists need to be careful to maintain adequate blood flow to the brain during surgery, especially when blood pressure drops. Drugs may be used to increase blood pressure, but some of these drugs can also affect blood flow to the brain. It is still unclear how to best maintain blood flow to the brain during surgery and how different types of anesthesia and drugs affect this process. The study aims to assess the clinical utility of a new technique that uses light-based neuromonitoring to measure changes in cerebral blood flow and metabolism. The investigators will recruit 80 adult patients undergoing surgery under general anesthesia and randomize them into one of four groups to evaluate the effects of different anesthetic agents and vasopressors on brain hemodynamics and metabolism. The study will include patients over 18 years of age with no history of neurological conditions, substance abuse, or contraindications to cerebral oximetry devices or specific anesthetic agents. The patients will receive standard anesthesia care and be monitored with our light-based neuromonitoring system. This study aims to demonstrate the device's ability to detect changes in cerebral hemodynamic parameters related to anesthesia induction and systemic hypotension. This study will also evaluate the effects of anesthetic maintenance agents and vasopressors on cerebral hemodynamics and neurovascular coupling. Read Less

The goal of this observational study focuses on understanding and addressing a subset of persistent neuropsychiatric symptoms occurring within 3 months after mild to moderate COVID-19 infection (COVID-DNP). COVID-DNP encompasses major depressive episodes (MDE) with or without additional neuropsychiatric symptoms. Read Less

This is a single institution Phase I-II study to evaluate the tolerability and Maximum Tolerated Dose (MTD) (Phase I) and efficacy (Phase II) of adding Niacin CRT™ to standard first line treatment (concurrent Radiation Therapy (RT) and Temozolomide (TMZ) following by monthly TMZ - AKA Stupp protocol) in patients with newly diagnosed glioblastoma isocitrate dehydrogenase (IDH) wild type.

Overall, this observational cohort study aims too: 1. Implement rapid trio WGS for all children presenting to our health systems with epilepsy onset under 12 months of age. 2. Utilize electronic healthcare records and research databases to unite phenotypic and genomic data and to create a "virtual" registry across all institutions that will promote ongoing discovery. 3. Assess the impact of early genetic diagnosis on epilepsy, developmental, and health economic outcomes through formal longitudinal assessments of all children enrolled. Read Less

Transcranial Ultrasound Stimulation (TUS) is an emerging non-invasive brain stimulation(NIBS) technique that can be used on both superficial and deep brain targets with a high spatial resolution as small as a few cubic millimeters. Neural correlates of TUS have yet been elucidated. To date, no intracranial recordings (i.e., local field potential \[LFP\]) have been captured during or after TUS in patients with movement disorders. In this study, we are aiming to profile basal ganglia LFP activity during and after TUS by using a DBS system that is capable of recording LFP. This can shed light on mechanisms of TUS, as well as allow identification of a neurophysiological biomarker that can be used to tune the TUS sonication parameters for future clinical trials.

The COVID-19 pandemic brought impaired smell and taste to the forefront of international public awareness and clinical importance. Loss of smell can impair awareness of environmental hazards, alter appetite, and have negative effects on social behavior and well-being. Despite the significant functional impact associated with impaired olfaction, few effective treatments are available. Olfactory training (OT), the mainstay of treatment, is a self-administered therapy which involves a routine of repetitive brief odor exposures over several weeks. The process has been shown to improve odor discrimination, identification and detection threshold. However, the structured design and daily time commitment may be difficult to adopt for some patients, leading to poor compliance. Moreover, OT only exposes patients to a limited number of odours, failing to replicate the complexity of odor mixtures experienced daily in our chemosensory environment. OT has mainly been studied with four conventional odours encompassing the major odor categories; phenyl ethyl alcohol/rose (flowery odor), eucalyptol (aromatic), citronellal/lemon (fruity), and eugenol (clove) (resinous); however, this neglects the importance of emphasizing odors that culturally specific or personally relevant to the patient. For some patients, these factors could hinder their ability to adopt and comply with therapy. In contrast, cooking is a culturally ubiquitous activity that is already performed daily by most people, and naturally exposes us to personally meaningful and culturally relevant odors. However, there have been no published studies investigating the impact that odors encountered during meal preparation have on olfactory performance and development. The present study aims to compare the olfactory effects of culinary skills training to those of a conventionally designed OT program. To achieve this, olfactory testing will be conducted on students enrolled in a professional culinary skills training program at Fanshawe College, and a control group consisting of students in non-olfactory dependent programs at the same institution. To compare the effect of cooking to conventional OT, the study will be repeated for a second semester and students will be asked to perform concurrent OT. Read Less

The Scleroderma Patient-centered Intervention Network (SPIN) is an organization established by researchers, health care providers, and people living with scleroderma (systemic sclerosis; SSc) from Canada, the United States, Mexico, Australia, France, Spain, and the United Kingdom. The objectives of SPIN are (1) to assemble a large cohort of SSc patients who complete outcome assessments regularly in order to learn more about important problems faced by people living with SSc and (2) to develop and test a series of internet-based interventions to help patients manage problems related to SSc, including a self-management program (SPIN-SELF Program). The SPIN-SELF Program was designed by SPIN members based on key tenets of behaviour change that have been successfully incorporated in programs for more common diseases and on patient input. It utilizes social modelling through educational videos of SSc patients describing their challenges and what they have done to cope with SSc, as well as videos teaching key self-management techniques. After an introduction to self-management and instructions on how to navigate the program, patients will have access to modules that are most relevant to their symptoms and disease management challenges. The program's modules address (1) pain; (2) skin care, finger ulcers, and Raynaud's; (3) sleep problems; (4) fatigue; (5) gastrointestinal symptoms; (6) itch; (7) emotions and stress; (8) body image concerns due to disfigurement; and (9) effective communication with healthcare providers. The proposed study is a feasibility trial with progression to full-scale randomized controlled trial (RCT), depending on whether stoppage criteria are met, of the SPIN Self-Management Program. The SPIN-SELF Program was previously feasibility tested as an online only, self-help intervention. However, uptake was low, thus the investigators have moved to a group-based format. SPIN-SELF participants randomized to intervention will access and use online self-management material, and this will be supported by videoconference group sessions, led by trained peer facilitators. In the SPIN-SELF feasibility trial with progression to full-scale trial, the investigators will evaluate the disease management self-efficacy of participants who use SPIN-SELF compared to usual care. Eligible SPIN Cohort participants and externally recruited participants, with low disease-management self-efficacy, will be randomized to the SPIN-SELF Program or to usual care only. In the feasibility portion, 40 eligible participants will be randomized. Unless the trial team determines, based on stoppage criteria, that trial procedures need important modifications thereby re-setting the full scale trial as a new trial, the outcome data of the participants in the feasibility portion will be utilized in the analyses of the full-scale trial. In the full-scale RCT, 524 participants will be randomized. Read Less
