The study aims to determine a diagnostic marker for regionally impaired myocardial oxygenation response in patients with suspected coronary artery stenosis. Read Less

This study aims to identify and assess new CMR techniques that can improve current CMR protocols. Read Less

This study aims to view variations in MRI measurements of the heart and the brain in people with anxiety versus healthy volunteers. The MRI measurements used will be Oxygenation-Sensitive Cardiac MRI (OS-CMR), a recent type of MRI which is safe, fast, and non-invasive. Read Less

The purpose of this study is to use MRI images using the OS-CMR technique to view the differences in the hearts of healthy volunteers and participants with a condition called Metabolic Syndrome. The objectives of this project are to compare these two groups and to view how health risks, blood test results, and the time since a Metabolic diagnosis can affect heart health. Read Less

The use of a lumbar brace following single-level lumbar fusion for degenerative spondylosis (non-traumatic) is variable between surgeons. Some surgeons prefer to prescribe a brace and others do not. There is a lack of guidelines and evidence to support either treatment option. The purpose of this study is to assess feasibility and collect preliminary data to conduct a larger, definitive trial to provide evidence as to whether prescribing a brace or not results in better or equal outcomes. Imaging by CT scan, one year after surgery, will be used to analyze bone fusion (healing), and functional and pain scores from patients during their recovery will be compared to identify differences between patients who wore a brace and those who did not.

Infants are at risk of developing motor and cognitive neurodevelopmental disabilities as a sequelae to hypoxic-ischemic brain injury during the perinatal period. It is an ongoing challenge to predict the severity and extent of future developmental impairment during the neonatal period. This study will help test the feasibility of conducting a large-scale study that evaluates the role of diffuse optical tomography as a bedside neuroimaging tool in complementing the prognostic value of conventional and diffusion weighted MRI for predicting neurodevelopmental outcome in neonates with perinatal hypoxic-ischemic brain injury.

Chronic olfactory dysfunction, both hyposmia and parosmia, from the COVID-19 pandemic is a growing public health crisis, affecting up to 1.2 million people in the United States. Olfactory dysfunction significantly impacts one's quality of life by decreasing the enjoyment of foods, creating environmental safety concerns, and affecting one's ability to perform specific jobs. Olfactory loss is also an independent predictor of anxiety, depression, and mortality. Recent research suggests that parosmia, more so than hyposmia, can increase anxiety, depression, and even suicidal ideation. While the pandemic has advanced the scientific community's interest in combating the burgeoning health crisis, few effective treatments currently exist for olfactory dysfunction. Persistent symptoms after an acute COVID-19 infection, or "Long COVID" symptoms, have been hypothesized to result from sympathetic nervous system dysfunction. Stellate ganglion blocks have been proposed to treat this hyper-sympathetic activation by blocking the sympathetic neuronal firing and resetting the balance of the autonomic nervous system. Studies before the COVID-19 pandemic have supported a beneficial effect of stellate ganglion blocks on olfactory dysfunction, and recent news reports and a published case series have described a dramatic benefit in both olfactory function and other long COVID symptoms in patients receiving stellate ganglion blocks. A previous pilot study using stellate ganglion blocks of 20 participants with persistent COVID-19 olfactory dysfunction resulted in modest improvements in subjective olfactory function, smell identification, and olfactory-specific quality of life, but it lacked a control group. Therefore, we propose a double-blinded, placebo-controlled, randomized clinical trial assessing the efficacy of a stellate ganglion block with Lidocaine versus saline injection in up to 50 participants with persistent COVID-19-associated olfactory dysfunction.

The goal of this clinical trial is to observe study participants' comfort and fit of their aligners with occlusal blocks, as well as evaluate the engagement of the blocks using the Invisalign® System with mandibular advancement featuring occlusal blocks Read Less

The global prevalence of diabetes is on the rise and with it increase in prevalence of diabetic foot ulcers (DFU). These recalcitrant wounds are difficult to manage and pose a heavy economic burden. Photobiomodulation (low level laser) is used for acceleration of wound healing. The current study is designed to evaluate the effectiveness of B-cure laser, a home-use low-level laser device, for acceleration of diabetic foot ulcer healing over standard treatment. Read Less

Fat tissue in different parts of the body has different characteristics. Several studies have associated abdominal fat to an increased risk for multiple metabolic diseases, such as type 2 diabetes and cardiovascular disease, compared with fat located under the skin at the hips and thighs. However, the investigators do not know how the abdominal fat causes or contributes to the development of these diseases or how the development of these disease may in turn cause or contribute to changes in the fat tissue. The general objective of this study is to understand these mechanisms. To investigate these questions, the study will recruit 140 participants, both men and women aged 18-65 years. The participants will be divided into three groups: 40 people with obesity, 40 with diabetes, and 60 lean individuals. Participants will be recruited from patients at the CIUSSS du Nord-de-l'Île-de Montréal - Hôpital du Sacré-Coeur de Montréal who are awaiting bariatric or general abdominal surgery, as well as from the general population in the Montreal area.

This phase II single-armed study will examine the clinical utility of retreating patients with osimertinib, in the third-line, following first-line treatment with osimertinib and second-line treatment with platinum and pemetrexed chemotherapy. The current standard of care for first-line Epidermal Growth Factor Receptor (EGFR) mutated Advanced Non-Small Cell Lung Cancer (aNSCLC) is osimertinib, followed by cytotoxic chemotherapy. The repeat of osimertinib following previous treatment failure is investigational, although supported by scientific rationale. The dosing and scheduling of osimertinib follows its use in approved settings. The investigators examine its tolerability and efficacy in this setting to ensure osimertinib is a safe third-line option for patients with Epidermal Growth Factor Receptor mutated (EGFR+) Advanced Non-Small Cell Lung Cancer(aNSCLC).

This first-in-human study will evaluate the safety, tolerability, pharmacokinetics, and antitumor activity of TORL-3-600 in patients with advanced cancer Read Less
