This study evaluates whether the combined treatment of methylphenidate and non-invasive brain stimulation, called intermittent theta burst stimulation, can effectively treat apathy in individuals with Alzheimer's disease or mixed AD/vascular dementia

Chemotherapy-induced nausea and vomiting (CINV) are among the most bothersome symptoms during cancer treatment according to children and their parents. Most children receiving highly emetogenic chemotherapy (HEC), including those receiving hematopoietic stem cell transplant (HSCT) conditioning, experience CIV despite receiving antiemetic prophylaxis. Olanzapine improves CINV control in adult cancer patients, has a track record of safe use in children with psychiatric illness, does not interact with chemotherapy and is inexpensive. We hypothesize that the addition of olanzapine to standard antiemetics will improve chemotherapy-induced vomiting (CIV) control in children receiving highly emetogenic chemotherapy

Placement of a ureteral stent is a common urological intervention. For decades there was no valid measures available to assess quality of life issues in patients with ureteral stents, which has hampered the understanding of such symptoms and their true impact. In order to improve the outcomes associated with the placement of a stent, a validated tool is needed to measure its impact and the amount of undesirable effects it produces on patients requiring the placement of a stent. In 2003, the team of the Bristol Urological Institute developed a validated questionnaire called the: URETERAL STENT SYMPTOM QUESTIONNAIRE (USSQ). The questionnaire contains 38 items included in 6 sections. Despite the obvious need of a validated questionnaire, the latter remains unused by the community of peer urologists. Many of urologists consider it too long to be used in clinical practice and even for research purposes. This issue motivated the Canadian Endourology Group (CEG) to work collaboratively on the development of the CANADIAN ENDOUROLOGY GROUP STENT SYMPTOM SCORE (CEGSSS) in order to provide clinicians with a more useful and validated tool. To fulfill this objective, the CEG proceeds in three phases. Phase 1. A systematic, deliberative, and participatory approach mostly through face to face meetings, including patients, clinicians, and researchers in the field of Endourology to identify a minimum needs-based set of domains and items that are, clinically relevant to be included in the CEGSSS in order to ensure optimal uptake in the clinical setting. Phase 2. A pilot study to assess feasibility/acceptability and further refine the proposed set of items selected in phase 1 of the study. Phase 3. A multicentric prospective study to evaluate the validity, reliability and sensitivity to change of the CEGSSS. This research project is conducted by the Canadian Endourology Group (CEG), a panel of experts in the field of endourology in Canada. The CEG is a national member-based organization dedicated to enabling the profession to provide the highest possible standards of endourological care and to advance the science of endourology by collaboratively: 1. Fostering excellence in endourological practice through advocacy, education, research and practice support tools, 2. Leading evidence-based clinical practice through the development of practice standards and guidelines in endourology, 3. Providing continuous professional development for Canadian endourologists along the career-path continuum, 4. Providing leadership in public education for endourological conditions.

Mpox is caused by a virus that can be spread through touching the affected skin of someone who has the infection, touching sheets or clothes that has been used by someone with the infection, or breathing in particles of virus from someone who has the infection. Mpox infection can cause skin and flu-like symptoms, but can also cause very few symptoms, or no symptoms at all. While the number of participants with mpox symptoms can be tracked, little is known about how many people have mpox, but experience few or no symptoms at all. To do this, a Canadian sample of gay, bisexual and other men who have sex with men (GBMSM) who are participating in a randomized controlled trial will be screened for mpox symptoms. Screening will include questions about whether they may be experiencing any mpox symptoms, history of past diagnosis of mpox, sexual history, and vaccination history and awareness. Swabs will be taken to test for the presence of mpox virus, and a blood sample will be taken to test for antibodies. Approximately 450 individuals will be recruited. The results will be descriptive in nature.

Cognitive impairment is well established in people with psychosis and is associated with cannabis use. The current study will investigate the neurobiological basis of cognitive change associated with 28-days of cannabis abstinence in people with psychosis and non-psychiatric controls with cannabis use. Participants will be randomized to a cannabis abstinent group or a non-abstinent control group and will undergo magnetic resonance imaging at baseline and following 28-days of abstinence. This study will help characterize the neuropathophysiological processes underlying cognitive dysfunction associated with cannabis use and its recovery which may guide the development of novel interventions for problematic cannabis use.

At present, it is not clear whether performing a hip arthroscopy at the same time as a PAO improves patient outcomes after surgery compared to a PAO alone. This research project will randomize patients to receive either a PAO alone, or a PAO and a hip arthroscopy at the same time.

This trial seeks to assess the feasibility of a full-scale, double-blind, placebo-controlled, randomized trial assessing whether low-dose colchicine (0.5 mg daily) reduces the risk of post-thrombotic syndrome (PTS) in patients with proximal lower extremity deep vein thrombosis (DVT).

In this study, the hypothesis being explored is that VO2Max and other CPET parameters can be accurately estimated from biosignals (namely, motion from accelerometers and cardiopulmonary variables from EKG) collected during activities of daily living using wearable biosensors worn by study participants. This study will aim to collect development and validation data for a machine learning algorithm and to evaluate the performance of the algorithm. A total of 1000 participants will be enrolled including: (Normal) 100 participants, self-reported healthy male and female participants aged 18 to 80 and (Standard of Care) 900 participants.

Chronic rhinosinusitis, also called chronic sinusitis, is a very common life-long disease affecting over 5% of the Canadian population. Its symptoms, including daily facial pain and headache, an inability to breath through the nose and complete smell loss, regularly impair one's ability to work and to enjoy and participate in daily activities. The annual cost of chronic sinusitis to Canada is estimated at $1.3 billion while the government pays an estimated $860 million yearly for chronic sinusitis treatment. Chronic sinusitis with polyps, the most common type of chronic sinusitis, is usually treated with a combination of medications and surgery. Until now, surgical treatment has only been performed in the operating room, at a cost of about $3500 per procedure. But, recent studies have shown that a new procedure, "in-clinic polyp removal", can provide an improvement in patient symptoms to levels equal to those for sinus surgery performed in a hospital operating room. Moreover, in clinic polyp removal has additional advantages including a shorter procedure recovery time, a significantly lower cost to the health care system (about one-tenth the cost or $450), and a shorter wait time for treatment. With the proposed pragmatic trial, the investigators will determine whether the in clinic polyp removal procedure is as good as sinus surgery in the operating room at controlling patient symptoms of chronic sinusitis. The investigators will also determine the cost and health-benefits for a patient, the healthcare system and for society of in clinic polyp removal in comparison to sinus surgery done in a hospital operating room. The investigators will then know if this new treatment, in clinic polyp removal, can replace sinus surgery as the standard of care for these patients.

The aim of this study is to determine if a single dose of psilocybin administered with motivational enhancement therapy (MET) can reduce heavy drinking in patients with an alcohol use disorder (AUD).
