This trial will compare tisagenlecleucel to standard of care in adult participants with relapsed or refractory (r/r) follicular lymphoma.

Lungs are made up of individual lobes. When a lung cancer tumour is detected in one of these lobes, surgeons typically perform a Lobectomy. A Lobectomy is the surgery most commonly done to treat early-stage lung cancer and requires removal of an entire lobe of the lung, which removes a large amount of lung tissue For patients with small tumours saving as much healthy lung tissue as possible is important. Each lobe of the lung has smaller sections called segments. When a lung cancer is in one of these segments, it is possible to remove that segment, without removing the entire lobe. This surgery is called a segmentectomy. Compared to a lobectomy, a segmentectomy saves a larger amount of healthy lung tissue. With the advances in screening technology for lung cancer tumours, an increasing amount of very small lung cancer tumours are being found, and the demand for segmentectomy is increasing. A segmentectomy is a hard surgery to perform robotically because it is difficult to view the tissue lines that separate each segment within the lobe. As a result, it is difficult for the surgeon to see exactly which pieces of tissue should be removed. Because of these challenges, many patients having robotic surgery will have a lobectomy, even if a full lobectomy is not needed. Near-Infrared Fluorescence (NIF) using indocyanine green (ICG) fluorescent dye is a recent advancement in the robotic platform of robotic surgery. The surgeon will view the CT scan to determine which segment the tumour is located in. Once identified, the surgeon will isolate the segment by cutting off the blood supply to that segment. Then ICG will be injected into a vein. It is expected that the entire lung, except the isolated segment, which will remain 'dark' as it was isolated from blood supply, will fluoresce, giving off a green hue when viewed with the da Vinci Firefly camera. The surgeon will identify 'dark' segment, and will remove it. A pathologist will examine the excised tissue to ensure that the tumour was removed in its entirety. Once confirmed, the surgeon will end the procedure. If the pathologist determines that the segment removed did not contain the entire tumour, then the surgeon will perform a routine lobectomy. This ensures patient safety and confirms that all participants will have the entire tumour removed from their lung.

Spinal cord stimulation (SCS) relies on stimulation of pain-relieving pathways in the spinal cord to treat chronic neuropathic pain. Traditional paresthesia-based SCS (PB-SCS) relies on providing analgesia through stimulation of spinal cord dorsal columns but it is often associated with attenuation of analgesic benefit and lack of acceptance of paresthesias. Recently introduced three different paresthesia-free (PF-SCS) modes of stimulation aim to overcome limitations of PB-SCS. Several questions regarding PB and PF SCS modes remain unanswered including the mechanisms of therapeutic benefit, criteria for selecting patients likely to benefit, and long-term outcomes. A concerted effort is required to understand and optimize utilization of SCS. This project has the twin goals of using neuroimaging techniques to understand mechanisms that underlies analgesic benefit from PB/PF-SCS modes and to identify criteria for selecting patients based on monitoring of pain and its related domains in patients undergoing SCS trials. Achieving these objectives will increase probability of analgesic benefit while minimizing adverse effects and knowledge gains from this study will be applicable to other therapies for chronic pain conditions.

ctDNALung-Detect is an investigator-initiated single arm, multi-institution study designed to assess the ctDNA detection rate and its association with Relapse Free Survival (RFS) in operable stage T1-T4 (T3,T4 multifocal) N0M0 non-small cell lung cancer (NSCLC) patients.

Approximately four thousand Canadians die by suicide every year, and suicide is the second leading cause of death in youth and young adults (15-34 years). Most people with depression experience thoughts of suicide and many will also plan and/or attempt suicide at some time in their life. There is an urgent need for new scalable treatments that can effectively reduce suicidality in people with depression. Cognitive behavioural therapy (CBT) reduces suicidal thoughts and behaviours, and can be delivered through the internet (i-CBT) making it more accessible and scalable. However, i-CBT has not been shown to rapidly reduce suicidal thoughts and behaviours (suicidality), such as within 24 hours. IV ketamine on the other hand has been shown to rapidly reduce thoughts of suicide, but not suicidal behaviours. Therefore, combining i-CBT with IV ketamine may be more effective reducing suicidality than i-CBT treatment with a control treatment. The investigators propose a 13-week, multi-site, study that looks at how combining i-CBT and IV ketamine treatment will affect suicidality in individuals with depression who have recently experienced suicidal thoughts and/or behaviours, but have not responded to previous treatment. All 110 participants will receive a weekly session of i-CBT for 13 weeks, but half will be randomly assigned to also receive six IV ketamine treatments or six IV midazolam treatments (control treatment) over the first initial 30 days. The investigators will measure changes in suicidal thoughts and behaviours before drug treatment and at the primary endpoint (i.e.,day 30), and after 3 months (i.e. Day 91) of the starting treatment.

Drivers aged 65+ depend on their car(s) to get to the places and see the people that are important to them. Losing a license in later life has been linked to higher rates of loneliness, depression, and even admission to long-term care; a fact that is particularly relevant when considering the impact of the COVID-19 pandemic. While drivers in this age group are among the safest on the road, they have one of the highest risks of collision when distance driven is considered and are more likely to be seriously injured or killed. Motor vehicle crashes and falls are the top causes of injury-related hospitalizations in seniors. Through a partnership with older adults, driving instructors, and health professionals, we developed the Refreshing Older Adult Driving Skills (ROADSkills) program. This program uses a Global Positioning System (GPS) device that can be placed in people's cars, which can track their real-world, everyday driving patterns, including speeding and hard braking, alongside video data of their behind-the-wheel behaviour. Using this data, a personalized video will be created using information captured by the device in the older driver's car. This study will determine if the older drivers who receive this video feedback perform better than those who do not receive such feedback. Because this is the first time a study will use this type of behavioural intervention, we are interested in hearing from older drivers about their experience of participating in the study. The findings will help us to design a larger, national study of the ROADSkills program in Canada.

To study the inflammatory response during and after radiotherapy, especially by measuring the concentration of an enzyme called autotaxin and its product LPA in the blood plasma.

Ketone bodies are produced by the liver during periods of food scarcity or severe carbohydrate restriction. Blood ketones are an alternative fuel source used by the brain, heart, and skeletal muscle during periods of fasting. Further, ketones bodies act as a signalling molecule that have pleiotropic effects that upregulate cellular stress-resistance pathways throughout the body. Oral supplements containing exogenous ketones have recently become available and represent a novel tool for increasing plasma ketone bodies without the need for dietary restriction. Early evidence suggests that oral ketone supplements may enhance cerebral blood flow and improve cognition. However, the dose-dependent effects of a single ketone supplement on cerebral blood flow and cognition in young adults is currently unknown. The purpose of this study is to characterize the effects of ingesting a high versus low dose of an oral ketone monoester on cerebral blood flow, circulating blood markers, and cognition in young adults. As an exploratory aim, this study will investigate how oxygen uptake kinetics during submaximal exercise are impacted 2 hours after ingestion of a ketone supplement. Recent findings indicate that ketone supplementation may impair exercise performance due to the physiological stress (i.e., pH disturbances) imposed by an acute ketone dose. Delaying exercise onset by 2 hours after ingestion of a ketone supplement may enhance oxygen kinetics in a dose-dependent manner.
