NCT04495556
The need for improved diagnostic methods in Multiple Sclerosis (MS) is widely recognized. Although Magnetic Resonance Imaging (MRI) is a longstanding tool for detecting MS lesions, diagnostic inaccuracies persist. Up to 20% of people diagnosed with MS (1 in 5) are later found not to have the disease. This is highly consequential, as more than two-thirds of misdiagnosed patients are unnecessarily exposed to risks from disease-modifying therapies, which in rare cases can be life-threatening. Moreover, the current standard in MS diagnosis - the McDonald criteria, which combine clinical symptoms and MRI findings - were developed from studies in people with typical clinical presentations of MS. This reduces the specificity of these criteria, rendering them uninformative for the nearly half of MS patients who present to neurologists with atypical or nonclassical symptoms. Timeliness of MS diagnosis is also key, as diagnostic delay is common in cases of relapsing-remitting MS and can carry severe and lifelong consequences. The CentrAl Vein Sign in MS (CAVS-MS) study has been designed to assess whether Central Vein Sign (CVS) criteria can help address some of these unmet diagnostic needs. It will specifically explore the role of presentation type by enrolling a mixed population of patients with typical clinical presentations (n = 200) and those with atypical presentations, including suggestive MRI findings in the absence of neurologic symptoms (n = 200) across North America.
NCT04317118
Background: Suicide is the second leading cause of death for young people ages 10-24 years. There is no gold standard for evaluating suicidal thoughts and behaviors in young people with autism spectrum disorder (ASD) or other neurodevelopmental disorders (NDD). Also, youth with ASD/NDD are often excluded from many research studies. Because of this, researchers need more data. They want to make sure they are asking the best questions for young people in clinics such as the National Institute of Mental Health (NIMH) clinic. They want to make sure they have the best data to determine if a person is at risk for hurting or killing himself or herself. Objective: To develop and assess the efficacy of a suicide screening tool for people with ASD/NDD. Eligibility: Youth ages 8 to 17 who are engaged in assessment or treatment at the NIMH for ASD or other NDD Design: Participants will fill out 4 questionnaires during a 1-hour meeting with study staff. They will answer questions about how they have been feeling. They will be asked if they think about or plan to hurt or kill themselves. They will also be asked if they have ever thought about it or planned it in the past. Other questions will assess their understanding of death. Participants can take a break if needed. Parents of the participants will be asked similar questions. Parents will be informed if their child has current thoughts of suicide. About 1 week after the initial assessment, parents will be contacted to fill out a follow-up questionnaire. It will take about 10 minutes to complete.

NCT02363296
Sub-Study: Phase Triggered Paired Associative Stimulation (PAS) (completed - analysis only) Background: -Previous research has shown that the brain s activity changes with changes in brain waves. We can study brain activity with a procedure called transcranial magnetic stimulation (TMS), a form of non-invasive brain stimulation. EEG allows for measuring ongoing brain waves. The goal of this study is to optimize TMS delivery by utilizing EEG-triggered TMS. Objectives: -To see if changes in brain waves change the brain and body s response to TMS. Eligibility: -Healthy, right-handed adults age 18-35. Design: * Participants will be screened under another protocol with medical history and physical exam. They may take a pregnancy test. They will have a magnetic resonance imaging (MRI) scan of the brain. For MRI, participants lie on a table that slides in and out of a metal tube that takes pictures. with: * Participants will have up to 4 outpatient visits lasting 2-3 hours each (4 outpatient visits). The following procedures may occur at a visit: * Magnetic resonance imaging (MRI): Participants lie on a table that slides into a machine that takes pictures of the brain. * Electroencephalography (EEG): Small electrodes on the scalp record brain waves. * Electromyography (EMG): Small sticky electrodes on the skin measure muscle activity. * Transcranial magnetic stimulation (TMS): A wire coil is held to the scalp. A brief electrical current passes through the coil and affects brain activity. Main Study: Influence on Plasticity of Brain Temperature (completed - analysis only) Background: \- Brain activity changes with changes in body temperature. Brain activity can be studied with a procedure called transcranial magnetic stimulation (TMS). Researchers want to cool the brain through the scalp using a cooling cap. They want to see if cooling changes the brain and body s response to TMS. Objectives: \- To look at the effects of cooling on the brain. Eligibility: \- Right-handed adults age 18-50 who can abstain from caffeine and tobacco. Design: * Participants will be screened with medical history and physical exam. They will be asked about alcohol use, smoking, and substance abuse. They may take a pregnancy test. They may have a magnetic resonance imaging (MRI) scan of the brain. For MRI, participants lie on a table that slides in and out of a metal tube that takes pictures. * Participants will have 3 outpatient visits. The following procedures will occur at each visit. * Participants will wear a cooling cap for up to 45 minutes. Cool water will flow through the cap. It will feel like an ice pack in a towel. Their core temperature will be monitored. Their temperature will also be measured under their tongue and on scalp, stomach, forearm, and calf. * Participants will have TMS before and after wearing the cap. A brief electrical current will pass through a wire coil held on their scalp. Electrodes that detect muscle movement will be placed on their hand. They will also have repetitive TMS, which uses repeated magnetic pulses. Their wrist will also receive a shock.

NCT07203911
The goal of this clinical trial is to improve the surgical treatment of patients with oral cancer. We will explore whether the use of surgeon performed ultrasound during these surgeries result in better tumor removal. We hypothesize that using intraoperative ultrasound to assist the resection results in more frequent clear surgical margins in oral cancer surgeries compared to standard methods. This improvement is associated with a reduced need for post-operative adjuvant therapies such as radiotherapy and reoperation, lower mortality rates, lower cancer recurrence, and enhanced quality of life for patients undergoing surgery for oral cancer. Participants will be randomized to either the control or intervention group: * Control group will receive standard treatment for oral cancer. * Intervention group will in addition to the standard treatment have surgery performed using ultrasound to guide the resection and evaluate resection margins intraoperatively. Outcomes: * Number of free surgical margins between control and intervention group. * Intraoperative surgeon assessed surgical margins compared to final histology report. * Dysphagia and quality of life questionnaires. * Recurrence rates. * Mortality rates. All participant will be followed-up at 3 months and 12 months with: * MDADI dysphagia questionnaire * EORTC head and neck cancer quality of life questionnaire * Follow-up on recurrrence and mortality.
