The standard or usual treatment for patients diagnosed with deep vein thrombosis or pulmonary embolism is treatment with blood thinners (called anticoagulants). While treatment of blood clots with blood thinners is effective, some research has shown that adding a statin (medication used to lower cholesterol) may give extra protection. It is thought that statins can improve how cells along the walls of the vein control inflammation, which can prevent new blood clots from forming. The medication in this study, rosuvastatin, is approved in Canada for use as a cholesterol-lowering medication. The use of rosuvastatin in this study is considered investigational. This means that Health Canada has not approved the use of rosuvastatin as a treatment for blood clots. However, it has been approved for use in this research study. The purpose of this study is to examine if adding a statin (rosuvastatin) to the usual blood thinner treatment will decrease the risk of another blood clot forming. The investigators also hope to discover if taking a statin reduces damage to your veins. To do this, some of the participants in this study will get rosuvastatin and others will receive a placebo (a substance that looks like the study rosuvastatin but does not have any active or medicinal ingredients). The placebo in this study is not intended to have any effect on your blood clot. A placebo is used to make the results of the study more reliable.

Anhedonia is a core feature of major depressive disorder (MDD) (DSM-5). Functional magnetic resonance imaging (fMRI) studies have associated anhedonia in MDD with altered frontostriatal activity and functional connectivity relative to controls. Conversely, antidepressant treatment is associated with increased ability for patients with MDD to sustain frontostriatal activity in a manner predictive of decrease in anhedonia and gains in daily positive affect. Novel interventions are needed to address anhedonia. Repetitive transcranial magnetic stimulation (rTMS) of the dorsolateral prefrontal cortex (DLPFC) has been shown to activate striatal reward circuits. Positive Affect Treatment (PAT) was developed to treat deficits in reward processing; a critical skill patients are trained on in PAT involves recounting and savouring of positive experiences. However, amotivation impedes some patients from engaging in positive activities, prompting the development of virtual reality reward training (VR RT) for this skill. Evidence is building that brain state at the time of rTMS impacts its therapeutic effect. For example, imaginal exposure and individualized symptom provocation just prior to rTMS enhances its therapeutic effect on post-traumatic stress disorder and obsessive-compulsive disorder, respectively. It is unknown whether VR RT can augment rTMS for MDD and if so whether it is mediated by enhancing changes in frontostriatal activity or functional connectivity. The current study is significant for multiple reasons. As mentioned, there is a paucity of effective treatments for anhedonia and this study may inform development of a novel treatment strategy that harnesses findings from affective neuroscience. Recent economic analysis suggests that rTMS can be more cost-effective than pharmacotherapy or ECT for treatment-resistant depression (Ontario Health, 2021). Our findings will provide insight on ways to synergize specific psychotherapeutic techniques with targeted stimulation of brain circuits to more effectively treat subtypes of depression.

This study is an open-label, single-arm, proof-of-concept study, wherein treatment resistant bipolar depression (TRBD) participants will receive one 25 mg dose of oral psilocybin accompanied by preparatory, monitoring, and integration psychotherapy sessions (psilocybin-assisted psychotherapy, or PAP). Using fMRI (functional magnetic resonance imaging), the findings of this study will provide data on the neurobiological mechanism of psilocybin in TRBD. The primary objective is to understand the dynamic role of amygdala activity by evaluating the neurobiological effects of a single psychedelic dose (25 mg) of oral psilocybin in individuals with a moderate to severe major depressive episode and a primary diagnosis of Bipolar II Disorder, with 2 or more failed treatment trials (i.e., treatment resistant bipolar depression \[TRBD\]). Neurobiological effects will be determined by evaluating the association between post-treatment right amygdala activity during the facial affect task (determined by fMRI one day after the psilocybin dose) and antidepressant effects (determined by changes in the Montgomery-Åsberg Depression Rating Scale \[MADRS\] scores over time, during the one-week period post-psilocybin dose). This is a single-arm, open-label clinical trial wherein all participants will receive the same study intervention. Hypothesis: Increased right amygdala activity on fMRI with emotional stimuli one day after psilocybin treatment will be associated with greater antidepressant effects in the one-week period post-treatment in individuals with TRBD.

Our project aims to develop a rapidly acquired and communicated MRI assessment and report that incorporates functional and structural imaging to convey information about functional neurological insults following traumatic brain injury (TBI) that are not typically visible on clinical imaging. Within this framework, there are two sub-studies. The first is a prospective study of patients with TBI who will have an MRI in the sub-acute period after their injury, followed by clinical assessments up to 90 days post-injury. A model will be developed to link MRI biomarkers to persistent symptoms of TBI. The second sub-study will use a focus group methodology to develop the report content and format with input from several groups of stakeholders.

Metabolic acidosis is a common problem that occurs with worsening chronic kidney disease. Dietary acid can build up when the kidneys are not working well. This can be associated with a higher risk of worsening kidney function and death. The usual treatment is a medication called sodium bicarbonate which works to balance the acids in the body. The medication however often does not work and causes side effects. Consumption of alkalizing fruit and vegetables may work as a treatment for metabolic acidosis. This trial is being done to see if fruit and vegetables, provided via home delivery, can become a viable management for metabolic acidosis in patients with chronic kidney disease.

Preterm birth, or birth before 37 weeks' gestation, is increasingly common, occurring in 8 percent of pregnancies in Canada. Preterm birth is associated with many health complications, particularly when the birth happens before 29 weeks' gestation. At this gestational age, the lungs are not fully developed and it is not uncommon for infants to have problems breathing at the time of birth. One complication that can arise is when an infant stops breathing and needs to be resuscitated. When preterm babies need to be resuscitated doctors must take special care because of the small infant size and the immaturity of the brain and lungs. Oxygen is used to resuscitate babies who need it, but unfortunately there is disagreement about the best oxygen concentration to use. Oxygen concentration is important because both too much and too little oxygen can cause brain injury. This research aims to fill this knowledge gap by participating in an international clinical trial to compare the effects of resuscitating babies less than 29 weeks' gestational age with either a low oxygen concentration or a high oxygen concentration. The oxygen concentrations have been selected using the best available knowledge. This will be a cluster randomized trial where each participating hospital will be randomized to either 30 or 60 percent oxygen for the recruitment of 30 infants, and afterwards randomized to the other group for the recruitment of another 30 infants. After the trial, the investigator will determine whether the babies resuscitated with low oxygen or those resuscitated with high oxygen have better survival and long-term health outcomes. This research fills a critical knowledge gap in the care of extremely preterm babies and will impact their survival both here in Canada and internationally.
