The purpose of this study is to see if one or two doses of psilocybin is more effective in relieving depressive symptoms in patients with treatment-resistant depression (TRD). Researchers also want to know if a second dose of psilocybin is safe and well-tolerated. This study will see if psilocybin is effective, safe, and well-tolerated by tracking changes in depressive symptoms, suicidality, and side effects. This study will also see if a second dose of psilocybin has an effect on quality of life, functioning, cognition (thinking, reasoning, remembering), and how long depressive symptoms improve (or worsen) after psilocybin is administered.

Chronic obstructive pulmonary disease (COPD) is a very common and chronic lung condition and is a leading cause of morbidity and death. These patients have persistent breathlessness and exercise intolerance, affecting their ability to carry out routine daily tasks. Standard COPD treatments include medicines/puffers as well as participation in a Pulmonary Rehabilitation (PR) program. PR programs are delivered by a diverse team of healthcare experts in exercise and nutrition. It is possible that an emerging nutritional oral supplement could target the muscular dysfunction seen in patients with COPD in part by promoting better working mitochondria, the energy 'engine' of muscle. A series of recently published studies in sedentary adults and in older adults have demonstrated the safety, tolerability, and potential clinical effectiveness of this supplement. In this regard, the investigators plan to lead a large randomized controlled trial (RCT) to test whether oral supplementation in patients with COPD who are also participating in a standard PR program will improve overall exercise performance. The investigators will also test muscle strength, cognition, body composition, and other clinically important outcomes such as quality of life. Lastly, the investigators will use muscle tissue from a subgroup of volunteers to investigate the effect on muscle/mitochondrial structure/function. The focus is actually the critical 'first step' before the larger RCT: a pilot and feasibility study on a smaller number of participants with COPD, as an important proof-of-concept that the larger study can, and should, be conducted.

This study is part of the development and validation of a non-invasive lung screening test which aim to identify early stage lung cancer in patients at high risk for lung cancer. Read Less

The goal of this pilot trial is to compare three meal strategies using an ultra-rapid insulin (Lyumjev) and an automated insulin delivery system. The meal strategies to be investigated are carbohydrate counting, qualitative meal announcement (e.g., low-carb meal), and meal detection. The investigators are doing this research to evaluate if carbohydrate counting can be simplified in patients with type 1 diabetes. Participants will test each meal strategy in random order, and each meal strategy will be 21 days long. For the duration of each meal strategy, participants will use an automated insulin delivery system or "artificial pancreas" with an ultra-rapid insulin called Lyumjev. Read Less

Repetitive transcranial magnetic stimulation (rTMS) is an alternative non-invasive treatment to help people quit smoking. rTMS uses a magnetic field to stimulate regions of the brain that are involved in addiction. The two brain regions that are stimulated are the insula and the dorsolateral prefrontal cortex, which are involved in drug craving and decision-making, respectively. The goal of this clinical trial is to learn more about the feasibility of offering rTMS as a treatment in the Nicotine Dependence Clinic (NDC) to help daily smokers to quit smoking. The NDC is at the Center for Addiction and Mental Health (CAMH) at 1025 Queen Street West, in Toronto, Canada. Participants will be asked to come to CAMH to: * Complete surveys and optional interviews to learn more about their opinions and experiences with this treatment * Start a treatment course that includes 3 weeks of daily (Monday to Friday) rTMS sessions followed by 3 weeks of weekly rTMS sessions for a total of 6 weeks. Each session lasts about 25 minutes and is provided by an rTMS technician with medical supervision. Objectives • Learning about the feasibility of rTMS as a treatment option for patients in the NDC will help us improve the treatment when offering it in other clinics, which may help improve smoking quit rates and people's overall health.

The investigators have spent the last decade uncovering unique metabolic and functional abnormalities in the brains of patients with spinal cord compression. Degenerative spinal cord compression represents a unique model of reversible spinal cord injury. In the investigator's previous work, they have demonstrated that cortical reorganization and recruitment is associated with metabolic changes in the brains of patients recovering from spinal cord compression and is correlated with recovery and improved neurological scores. The goal of this study is to combine a rigorous platform of clinical care that includes preoperative evaluation, surgery, and rehabilitation, with state of the art imaging techniques to demonstrate how rehabilitative therapy can increase brain plasticity and recovery of neurological function in patients with spinal cord injury. Neurological function will be carefully evaluated in two groups of patients, those receiving rehabilitation and those not receiving rehabilitation after spine surgery, and will be correlated with the results of advanced imaging.

The goal of this clinical trial is to evaluate the effectiveness of the online modality of the Make the Connection (MTC) program in caregivers of infants and young children. The main questions it aims to answer are: * Does the MTC online program result in changes in the child-caregiver relationship, caregiver self-competence, caregiver stress, caregiver depression, as well as caregiver and child emotion regulation, as compared to a waitlist control? * Are caregivers who experience psychosocial risks (e.g., elevated depression scores, social isolation) deriving similar benefits in the child-caregiver relationship, caregiver self-competence, caregiver stress, caregiver depression, as well as caregiver and child emotion regulation as caregivers who are not? * What are some of the barriers, facilitators, perceived benefits, and risks to participating in the MTC online program from the perspective of caregivers? Participants will be randomly placed into either the intervention group or the waitlist control group. Both groups will be asked to complete a pre-intervention questionnaire, the intervention group will be invited to complete the 8-week MTC online program consisting of a weekly 15-minute module, and both groups will lastly be asked to complete a post-intervention questionnaire. Researchers will compare the intervention group and the waitlist control group to see if the MTC online program results in improved caregiver-child bond, caregiver self-efficacy, caregiver stress, and caregiver depression.

Every year, thousands of Canadians are diagnosed with degenerative cervical myelopathy (DCM), a form of non-traumatic injury caused by spinal cord compression in the neck. While DCM causes a range of symptoms, one of the most disabling is loss of hand dexterity. Surgical decompression is standard treatment for DCM, but reduced dexterity often remains. The investigators have developed a portable, easy-to-use dexterity assessment tool for measuring hand dexterity. Hand function is often assessed using tools incapable of measuring subtle changes in function, limiting a clinician's ability to monitor progression of or recovery from a disease over time. The hope is that if subtle changes in function are identified early, leading to an early DCM diagnosis and treatment, this may prevent patients from experiencing a greater loss of hand function. The goals of this study are to determine the relationship between dexterity and myelopathy severity, as well as to establish the validity and reliability of the dexterity tool. This will be done by assessing dexterity using the dexterity tool in DCM patients (to determine the relationship between disease severity and dexterity, and measure validity) and healthy participants (to establish reliability).

Postpartum (child age 0-5 years) mental health problems are common, with prevalence rates ranging from 15-20% for depression, 3-43% for anxiety, and approximately 30% for anger. Depression, anxiety, and anger often occur comorbidly. If left untreated, these disorders can be long-lasting and lead to child behaviour problems, brain changes, and risk for later mental illness. We developed an app-based treatment for parental mental illness: Building Emotional Awareness and Mental Health in Parenting (BEAM). The BEAM program includes mental health and parenting videos, peer coaching, as well as a forum and drop-in Zoom sessions where parents can connect with each other to receive and provide social support. The program is supported by peer coaches (parents with lived experience of recovery from mental illness and who may have received emotion-focused parenting support) and supervised by clinically-trained staff. Peer coaches check-in with parents weekly to support their progress. Our study will see the BEAM app's effect on parent mental health, parenting stress, child behaviour, and child brain structure and function. 240 parents with high depression, anxiety, and/or anger symptoms will be recruited, with half forming the treatment-as-usual group.
