This is a single institutional registry-based, prospective, observational study to describe radiation oncologists' decision making during evaluation of patients and to compare real-world outcomes of SBRT vs CRT. A registry-based trial involves observing the effect of something without manipulating it. Read Less

This is a prospective, randomized phase II trial investigating if radiation treatment delivered every other day for 2 weeks has the same side effects as radiation treatment delivered once weekly for 6 weeks. Read Less

This is a multi arm, single center, investigator initiated study to investigate online adaptive radiotherapy and biomarker development in patients with newly diagnosed HNSCC (Head and Neck Squamous Cell Carcinoma) receiving curative therapy. The study will consist of two prospective arms. In Arm 1 up to 100 HNSCC patients receiving (CT)RT (computed tomography-based radiation therapy) will receive up to weekly non-contrast MRI (magnetic resonance imaging) scans during treatment. Arm 2 consists of two cohorts. In cohort A up to 20 healthy volunteers will undergo non-contrast MRI at two time points. In cohort B up to 53 patients planned to receive curative (chemo) radiotherapy for HNSCC will undergo two baseline MRI scans, one MRI in week 2 and week 4, and final MRI scan 6-8 weeks after completion of treatment.

Improved outcomes for high-grade gliomas (HGG) require advances in our ability to monitor changes to tumour biology using non-surgical approaches. "Liquid biopsy" is a term used to describe a technique whereby tumour DNA, which has been shed off and then circulates through the blood stream, is detected and analyzed. Our goal is to develop a new type of liquid biopsy that is suitable for primary brain tumours that uses a method that is highly sensitive and allows for ongoing analysis of these tumours. Read Less

The purpose of this open-label study is to assess the safety, tolerability, pharmacodynamics, and pharmacokinetics of WVE-006 in participants with alpha-1 antitrypsin deficiency (AATD) following Period 1 single ascending dose (SAD) and Period 2 multiple ascending doses (MAD), respectively.

Breast cancer predominates among cancer diagnoses in Canadian women. It accounts for around 25% of new cases and contributes to 13% of all cancer-related deaths. In 2020, almost 27,400 Canadian women were diagnosed with breast cancer and 5,000 of them died from it. Mammography is still the preferred method for screening for breast cancer. Although progress has been made over the years, mammography does have its drawbacks. These include physical discomfort for patients, exposure to X-rays and reduced effectiveness in dense breasts. The study team is therefore interested in developing a new breast cancer detection method, the BRAVE method. The BRAVE method, short for "BRA-based Visco-Elastography", uses the high contrast of elastic stiffness in malignant breast tumors to detect possible cancer cases without the need for X-rays or breast compression. The first phase, carried out on a small scale pilot study, aimed to assess the method's ability to distinguish a breast with no abnormalities from one with confirmed cancer. The second phase (current phase), carried out on a larger scale, aims to confirm the sensitivity and specificity of the method in detecting malignant lesions, i.e. to determine whether the method is capable of distinguishing between several types of breast masses.

This is an interventional, single-centre, single-arm, non-randomized, prospective, feasibility trial investigating salvage MR-guided High-Dose-Rate brachytherapy for prostate bed recurrence after postoperative radiotherapy. Read Less

This is a prospective observational study which aims to identify individuals predisposed to developing myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML) could improve patient outcomes in different ways. First, it will enable improved patient selection for PRRT where alternative treatment options are available. Second, understanding the final pathway and how it is modulated by PRRT could allow the design of strategies to halt this process. Third, while it is unknown whether the development of MDS and AML is a late effect of radiopharmaceuticals in general or it is confined to cancer populations or specific radioisotopes will need to be confirmed. Finally, understanding this devastating complication is expected to be the cornerstone towards advancing radiopharmaceuticals' role in the adjuvant setting. Read Less

The purpose of this randomized controlled pilot trial is to test the effectiveness of a six-week tailored physical activity program with and without peer mentoring on the psychological constructs and exercise behaviour of inactive undergraduate women. The objectives are to: * Quantify the degree to which a peer-mentorship intervention affects exercise motivation determined through three basic psychological needs (i.e., autonomy, competence, and relatedness). * Examine general psychological distress and exercise engagement throughout the study. * Qualitatively explore participants' experiences following the completion of the program using an open-ended survey to gain a better understanding of its impact. Researchers will compare the parallel arm conditions to see how the inclusion of social support impacts exercise engagement. Participants will be asked to engage in exercise three times a week at the campus gym; those in the intervention condition will have an assigned peer-mentor who will join them for one weekly session and virtually communicate with them between sessions.

Antiretroviral therapy or ART blocks HIV replication reducing plasma viral loads to undetectable levels but has no effect on persistently infected cells in the body, called the virus reservoir. These cells carry infectious HIV capable of restarting HIV replication if therapy is stopped. The reservoir is so stable forcing people to adhere life-long ART. Over 5% of ART adherent individuals continue to have residual non-suppressive viremia (NSV) detected by clinical assays (40-400 copies/ml). Residual viremia reflects a more persistent reservoir and has the potential for increased morbidity. For eg., persistent expression of HIV proteins contributes to inflammation, and can lead to comorbidities. Recently, a novel way to target this reservoir called "TACK" or "Targeted activator of cell killing" is proposed. TACK compounds only target HIV infected cells and directly kill them by inducing a natural killing program (called the inflammasome). Recently the HIV drug, Efavirenz (EFV), which was used to suppress HIV replication for decades, has now been shown to also be a TACK compound. This pilot study will evaluate the impact of Efavirenz (EFV) in reducing HIV persistence by its ability to be a TACK molecule. So in addition to blocking HIV growth, this compound when added to a current ART regimen can kill HIV infected cells in the test tube. We aim to harness this effect to determine whether the addition of EFV to the current ART regimen in people with NSV can suppress the viremia to undetectable levels by killing those cells. NSV represents the "the tip of the iceberg" of those with bigger reservoirs and represents a challenging clinical scenario in dire need of new diagnostic and therapeutic options. This pilot study will spark larger clinical trials to advance HIV cure strategies, and will provide new tools to improve the clinical management of people living with HIV. Read Less

Play is an important activity for children. Almost all children play, but what is play? It is not easy to define play. In the past, people believed that children played to burn their energy. Now, it is known that play is important for children's growth. Some kids with disabilities cannot play. Many experts use play to teach children specific skills. People often forget that play is a child's right. It is important to help all children play. The first step is to define play and find what features are important in helping a child with a disability play. There are some models of play. But they are not complete. They do not look at play as a whole. Some models are just about playfulness, and some are about playing with others. Having a model that defines play helps researchers and clinicians think about play and the different parts of it. Then, when a child cannot play, experts can fix the part that is not working. Investigators want to introduce a model of play in this project. Investigators want to edit and complete it in three steps. First, Investigators will ask parents and children with disabilities about things that help or do not help them play; then, investigators will give Lego robots to kids that they will build with help and play with them for a few weeks. And at the end, investigators will ask therapists and other experts about our model of play. This model will be edited during the study. Read Less
