The purpose of this exploratory study is to evaluate the effects of inhaled epinephrine in patients with known or suspected metabisulfite sensitivity who experience a systemic allergic reaction (SAR) while undergoing allergy testing, immunotherapy or oral challenges.

The standard treatment for acute graft-vs-host disease (GVHD) is to suppress the activity of the donor immune cells using steroid medications such as prednisone. Although most GVHD, especially in children, responds well to treatment, sometimes (around 1/3 of the time) there is either no response to steroids or the response does not last. In those cases, the GVHD can become dangerous and even life-threatening. Unfortunately, doctors cannot predict who will have a good response to treatment based on symptom severity or initial response to steroids. As a result, nearly all children who develop GVHD are treated with long courses of high dose steroids even though that means many patients receive more treatment than they probably need. Steroid treatment can cause short-term complications like infections, high blood sugar, high blood pressure, muscle weakness, depression, anxiety, and problems sleeping and long-term complications like bone damage, cataracts in the eyes, and decreased growth. The risk of these complications increases with higher doses of steroids and longer treatment. It is important to find ways to decrease the steroid treatment in patients who do not need long courses. The doctors conducting this research have developed a blood test (GVHD biomarkers) that predicts whether a patient will respond well to steroids. The study team found that children who have low GVHD biomarkers at the start of treatment and for the first two weeks of treatment have a very high response rate to steroids. In this study, the study team will monitor GVHD symptoms and biomarkers during treatment and taper steroids quickly in patients who have GVHD that is expected to respond very well to treatment. The study team will assess how many patients respond well to lower steroid dosing and what steroid complications develop. The study team will also use surveys to obtain the patient's own assessment of their quality of life (down to age 5 years).

The objective of this trial is to determine the effects of citicoline on cognitive performance for attention in healthy Men and Women compared to a placebo.

Neuropathic pain is a common complication following spinal cord injury (SCI) that significantly decreases quality of life. Treatment options are limited, and current treatments can have significant side effects. Those with SCI have identified a need for additional treatment options, particularly those that are not medications. Nabilone and an anti-inflammatory diet are two treatments that may provide pain relief while being better tolerated. This study will evaluate the benefits of these treatments for neuropathic pain after SCI. Study participants will receive either an anti-inflammatory diet or a placebo diet, and nabilone or a placebo for 4 weeks. It is expected that an anti-inflammatory diet and nabilone will significantly decrease pain intensity and improve function. The combination of both treatments together is expected to have a greater effect than each alone.

The goal of this clinical trial is to learn about how well tezepelumab (pronounced TEZ e PEL ue mab), a Health Canada-approved drug for severe asthma, works in participants with coexisting allergic asthma and allergic rhinitis (hayfever). The main questions it aims to answer are: * How well does the study drug work to reduce nasal symptoms following exposure to an allergen after 6 doses, and after 12 doses? * Does the study drug reduce chemicals found in the nose known to be involved in the allergic rhinitis response? Both allergic and non-allergic participants will be enrolled in the study. Non-allergic participants will: * Not be receiving the study drug. * Be exposed to allergen via the Nasal Allergen Challenge, which involves the administration of allergen extract directly to the nose. * Complete nasal symptom and quality of life questionnaires * Have nasal fluid and blood samples collected at various time points up to 24 hours following allergen exposure. * Visit the clinic 3 separate times: * At a screening visit to determine their eligibility to participate in the study * At the baseline Nasal Allergen Challenge visit * At the 24-hour post-Nasal Allergen Challenge follow-up visit Allergic participants will: * Receive one dose of tezepelumab every 1 month for 12 months. Tezepelumab will be administered as an injection into the fatty layer just beneath the skin on the stomach, arm, or thigh. * Be exposed to allergen via the Nasal Allergen Challenge, which involves the administration of allergen extract directly to the nose. * Complete nasal symptom and quality of life questionnaires * Have nasal fluid and blood samples collected at various time points up to 24 hours following allergen exposure. * Visit the clinic 17 separate times: * At a screening visit to determine their eligibility to participate in the study * At the baseline, 6-month, and 12-month Nasal Allergen Challenge visits * At each 24-hour post-Nasal Allergen Challenge follow-up visit * For each dose of the study drug The investigator will compare changes in nasal symptoms and allergic chemicals measured from nasal fluid and blood samples between non-allergic participants and allergic participants at baseline and at 6- and 12-months following the use of the study drug.

This study evaluates the impact of conjugated estrogens/ bazedoxifene (CE/ BZA) on the mood (depression and anxiety) in peri- and early menopausal women.

The purpose of this study is to investigate whether the gut bacteria in IBD patients cause ongoing abdominal pain, even when the disease is calm. Many inflammatory bowel disease (IBD) patients have this pain, regardless of whether their disease is active or not. This might be linked to an imbalance in gut bacteria. Certain IBD patients with persistent abdominal pain experience increased sensitivity in their gut due to bacteria producing LPC and LPA. Our goal is to explore the connection between bacterial LPC/LPA levels and symptoms in IBD patients with long-lasting abdominal pain. Additionally, we aim to pinpoint the specific bacteria responsible for producing LPC/LPA, which in turn causes chronic abdominal pain in these patients.

Bone is a common site of metastasis for a range of malignancies. Bone metastases have the potential to cause significant morbidity including pain, impairment of ambulation and reduced functional independence. Previous research has shown that pathological fractures are observed in 9 to 29 percent of patients with long bone metastases, and a high proportion of these require surgical intervention to relieve pain and restore function. The goal of this study is to describe the clinical outcomes of patients with femoral metastases at high risk of pathological fracture. Patients referred for treatment of femoral metastases at high risk of fracture will be followed prospectively after undergoing with surgery (± post-operative radiotherapy), or radiotherapy alone. Patient and disease characteristics, ambulatory status and limb function will be documented before treatment. These Clinical outcomes of participants in each treatment group will be measured 6 weeks after treatment, and 3- and 6 months after enrolment, with particular reference to patient-reported outcomes relating to pain, ambulatory status, limb function and quality of life.

This study is designed to test the hypothesis that poor cerebral perfusion during critical illness is a risk factor for acute and long-term neurological dysfunction among survivors. We use near-infrared spectroscopy to measure brain tissue oxygenation as a non-invasive surrogate marker for cerebral perfusion. Acute neurological dysfunction is defined as the presence of delirium, which is assessed using the Confusion Assessment Method-Intensive Care Unit (CAM-ICU). Chronic neurological dysfunction is defined as having quantitative impairments on robotic testing (KINARM robot) and traditional neuropsychological screening (Repeatable Battery for the Assessment of Neuropsychological Status).

The goal of this clinical trial is to test the impact of a novel dual-task EMG Biofeedback training method for improving balance in individuals living with multiple sclerosis. The main question\[s\] it aims to answer are: * Does dual-task EMG biofeedback training deliver lasting balance benefits up to 3 months following the intervention? * Are the benefits greater than those for participation in traditional balance training exercises? * Do the benefits vary with the severity of disability? Participants will receive either EMG Biofeedback (EMG-BF) training or traditional balance exercise (BAL-EX) training. Both treatments involve three 30-minute sessions of the training every week for 6 weeks (18 sessions). During the sessions, participants in the EMG-BF treatment group will perform targeted exercises using feedback from adhesive (sticker) sensors on their arms and legs. Participants in the BAL-EX treatment group will following an instructor through balance training movements that are traditionally prescribed by physiotherapists to improve balance. Measurements will be taken at the beginning of the study, after six weeks of training, and three months after the end of training. Researchers will compare the groups to see if balance and related outcomes are improved more by 6-weeks of EMG-BF training than BAL-EX.
