Depression is a leading cause of disability worldwide, affecting up to 300 million people globally. Despite its high prevalence and debilitating effects, only one-third of patients newly diagnosed with depression initiate treatment. Electronic cognitive behavioural therapy (e-CBT) is an effective treatment for depression and is a feasible solution to make mental health care more accessible. Due to its online format, e-CBT can be combined with variable therapist engagement to address different care needs. Typically, a multi-professional care team determines which combination therapy is the most beneficial to the patient. However, this process can add to the costs of these programs. Artificial intelligence (AI) technology has been proposed to offset these costs. Therefore, this study aims to determine a cost-effective method to decrease depressive symptoms and increase treatment adherence to e-CBT. This will be done by comparing AI technology to a multi-professional care team when allocating the correct intensity of care for individuals diagnosed with depression. This study is a double-blinded randomized controlled trial recruiting individuals (n = 186) experiencing depression according to the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5). The degree of care intensity a participant will receive will be randomly decided by either: (1) a machine learning algorithm (n = 93), or (2) an assessment made by a group of healthcare professionals (n = 93). Subsequently, participants will receive depression-specific e-CBT treatment through the secure online platform, OPTT. There will be three available intensities of therapist interaction: (1) e-CBT; (2) e-CBT with a 15-20-minute phone/video call; and (3) e-CBT with pharmacotherapy. This approach aims to accurately allocate care tailored to each patient's needs, allowing for more efficient use of resources.

The investigators want to study if lower doses of chemotherapy will help babies with SCID to achieve good immunity with less short and long-term risks of complications after transplantation. This trial identifies babies with types of immune deficiencies that are most likely to succeed with this approach and offers them transplant early in life before they get severe infections or later if their infections are under control. It includes only patients receiving unrelated or mismatched related donor transplants. The study will test if patients receiving transplant using either a low dose busulfan or a medium dose busulfan will have immune recovery of both T and B cells, measured by the ability to respond to immunizations after transplant. The exact regimen depends on the subtype of SCID the patient has. Donors used for transplant must be unrelated or half-matched related (haploidentical) donors, and peripheral blood stem cells must be used. To minimize the chance of graft-versus-host disease (GVHD), the stem cells will have most, but not all, of the T cells removed, using a newer, experimental approach of a well-established technology. Once the stem cell transplant is completed, patients will be followed for 3 years. Approximately 9-18 months after the transplant, vaccinations will be administered, and a blood test measuring whether your child's body has responded to the vaccine will be collected.

Intracytoplasmic sperm injection (ICSI) is one of the standard clinical treatments for infertility. ICSI involves the injection of a single sperm into an oocyte with a sharp micropipette. Injecting a sperm with DNA fragmentation (i.e., physical breakage of the DNA double strands) into the oocyte deterministically lowers the IVF fertilization rate \[1\]\[2\] and increases the miscarriage rate \[3\]\[4\]. Since the invention of ICSI in 1992, single sperm selection in ICSI has been made manually by embryologists, who select sperm by qualitatively choosing sperm with "good" motility and/or morphology based on their empirical experience. This involves significant subjectivity and inconsistency. We have developed a robotic system to select sperm with low sperm DNA fragmentation. Automated sperm selection also eliminates the subjectivity and inconsistency in manual sperm selection. The system consists of a camera to acquire images of sperm and a software to analyze the images. Embryologists select sperm by observing the same sperm characteristics as in the software criteria (e.g., speed etc.), but the software provides a more accurate and quantitative measure of sperm characteristics, thus ensuring the selected sperm have low DNA fragmentation.

The goal of this research study is to evaluate the performance of two experimental tests, namely Liquid Biopsy and Positron Emission Mammography (PEM) in women at high risk of breast cancer. The plan for this study is to assess whether findings from the combination or each individual test can assist radiologists in visualizing and characterizing beast abnormalities. Liquid Biopsy is a blood test that can detect early tumours in patients with malignancies, while PEM is an imaging tool equipped with a high-resolution camera that uses a low dose of injected positron emitting isotope to locate breast tumours. Participation in this study entails a blood draw for Liquid Biopsy test and a PEM imaging exam before undergoing a magnetic resonance imaging (MRI) - guided biopsy for a suspicious breast lesion. If PEM and/or Liquid Biopsy provide accurate information to assist radiologists in visualizing and characterizing breast abnormalities, this method may serve as the first step towards establishing these genomic and new imaging technologies as new diagnostic modalities and ultimately reduce the unnecessary biopsies and anxiety in high-risk populations.

Breast cancer is the most commonly occurring cancer in women. Currently, breast conservation surgery (BCS) is the treatment most often prescribed. BCS involves removing the tumor while conserving the greatest amount of healthy breast tissue. Under standard white light, tumor borders are difficult for the surgeons to visualize. Therefore, between 30-70% of patients require a second operation to remove remaining cancerous tissue that wasn't detected during the initial surgery. Thus, there is an urgent clinical need for a new imaging tool that improves tumor visualization during the first surgery. PRODIGI, a new hand-held optical imaging device, uses a safe violet-blue light to detect fluorescence signals in the tissue. Different tissues are associated with specific fluorescent colors and therefore the device can be used to differentiate between tumor and healthy breast tissue. Based on previous clinical data, PRODIGI can distinguish some tumors from normal tissues, but is not specific enough to detect a difference across all breast tumor types. The fluorescent contrast drug 5-aminolevulinic acid (5-ALA) accumulates in tumors naturally and previous research has shown that 5-ALA increases tumor-normal tissue fluorescence contrast. In this observational clinical study, PRODIGI and 5-ALA will be used to visualize tumor borders during BCS. 5-ALA induced fluorescent images from the surgical sample and the surgical bed obtained by PRODIGI will be compared retrospectively with the images taken under standard white light and/or autofluorescence. The technology's ability to accurately identify tumor borders better than conventional practice will be confirmed by tissue pathology.

The likelihood of exposure to overheated indoor environments is increasing as climate change is exacerbating the frequency and severity of hot weather and extreme heat events. Prolonged exposure to excessive heat stress can result in a deterioration in physiological function leading to a myriad of pathophysiological conditions (e.g., heat exhaustion, acute kidney injury, adverse cardiovascular events, heat stroke) that if left untreated can lead to death. While the relationship between extreme heat events and human health has been assessed in relation to outdoor exposure to high heat conditions, relatively little is known about the effects of daylong exposures to indoor overheating on the body's physiology. In this study, investigators will examine the change in physiological responses (i.e., thermal, cardiovascular) in young (18-35 years) adults exposed to successive days and nights of high indoor temperatures typical of conditions recording in dwellings without air conditioning during the 2021 Western Heat Dome. Specifically, study participants will be housed in a large environmental chamber (outfitted with bed, work space, sitting area, kitchen and bathroom) for three successive days (three days and two nights) while exposed to indoor overheating where daytime temperatures will be maintained at 36°C (45% relative humidity; note: 36°C, temperatures experienced in homes without air-conditioning) for a 10-hour daytime exposure period (DAYTIME: defined as the time period from 9:00 to 19:00). For the nighttime exposure period (NIGHTTIME: defined as the time period from 19:00 to 9:00), participants will be exposed to nighttime temperatures fixed at 31°C (45% relative humidity; note: reductions in indoor temperatures during the nighttime in large urban centers range between 4-6°C). Participants will be permitted to move freely throughout the day in the chamber, but will be restricted from performing any physical activity except for the completion of a battery of tests (cardiovascular, cognitive and posture assessments performed prior to (as performed between 7:00 and 9:00) and the end (as performed between 17:00 and 19:00) of the daytime exposure). During the nighttime period, participants will be permitted to move freely until they decide to go to bed.

Arteriovenous malformation (AVM) is a tangle of abnormal vessels that can progress through life and cause significant bleeding, deformity, pain, and deficits in day-to-day activities. Surgery is a common treatment option for patients with AVMs where the goal is to safely remove the entire AVM without causing complications. While any surgery has its potential risks, most of the potential modifiable risk factors relate to the AVM's structure, such as the AVM size or presence of high risk structural features seen on scans. The purpose of this pilot study is to see whether taking an oral medication called Trametinib can improve upon the AVM structure in adult patients before their scheduled surgery.
