There are about 28871 clinical studies being (or have been) conducted in Canada. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The primary objective of the current study is to investigate the effect of two probiotic formulations on task-switching following acute stress in healthy, adult action video gamers. It is hypothesized that the participants that consume the probiotic formulations will have improved task-switching performance following acute stress compared to those who consume a placebo.
There is a significant lack of information on drug secretion into milk and infant exposure. As a first step to address this issue, the investigators examine milk concentrations of selected drugs prescribed to breastfeeding women, which lack milk excretion data. Milk data will be analyzed using population pharmacokinetic approaches, when possible, and acquired data of drug concentration profiles in milk will be combined with infant physiologically-based pharmacokinetic (PBPK) models to predict infant exposure levels.
A first-in-human, Phase 1 trial to evaluate safety, tolerability, and immunogenicity of Inventprise's (IVT) 25-valent pneumococcal conjugate vaccine (IVT PCV-25)
Investigation of the effect of mechanical ventilation on biomarkers of microvascular damage
The diagnosis of neurocognitive disorders such as early Alzheimer's disease (AD) or primary progressive aphasia (PPA) is particularly difficult and constantly evolving, often leading to diagnostic erraticity. However, several studies have shown that graphic parameters are affected in people with moderate to severe Alzheimer's disease. The use of new technologies in the study and analysis of the abilities of people with neurodegenerative diseases is increasingly recommended. The use of a digital tablet with a stylus makes it possible to objectivize the kinematic parameters of writing (pressure, inclination, speed, jerk, time of writing task) and thus would allow a low-cost diffusion of this technology in particular by including it in already existing screening batteries. The overall objective of the project is to characterize and compare the graphical markers of a writing task, either language-based (writing words, non-words, sentences) or non-language-based (drawing shapes), in patients with PPA, early-stage Alzheimer's disease (i.e., at the stage of minor neurocognitive disorders and major neurocognitive disorders at the beginning of the disease), and in people with no cognitive disorders.
Turmeric is recognized as a bioactive compound with potential benefits for human health. This study compares the pharmacokinetic profile of the Turmeric test product to a comparator.
This retrospective collaborative study on persistent exercise intolerance after COVID-19 offers to perform a large descriptive analysis of CPET performed in real-life by pulmonologists, cardiologists and physiologists. Indeed, these practicians are regularly consulted for a persistent intolerance to exercise expressed by dyspnea and/or frank fatigability sometimes associated with muscular or thoracic pain. When these complaints persist beyond 3 months after the first symptoms, it is legitimate to perform a CPET: - Either to evaluate the functional impact of an identified organ deficiency (e.g. myocarditis, pulmonary fibrosis, etc.), - Or, in the absence of formal arguments for an identified organ deficiency, to observe possible abnormalities in physiological responses during an incremental exercise test, likely to explain the persistence of symptoms and intolerance to exercise. Indeed, the recent literature highlights the presence of non-specific ventilatory and cardio-circulatory abnormalities leading to various physio-pathological observations. Unfortunately, these reports now concern relatively small numbers of patients with very diverse clinical forms of Covid, comorbidities and habitus. In order to improve the understanding of persistent symptoms and in particular the diversity of physiological response presentations, the investigators propose to collect a very large amount of data through a web-based platform designed to collect the measurements made throughout the exercise test directly from the ergospirometer. The relevant data covers the period from January 2, 2020 to December 31, 2022 (i.e. 35 months), The retrospective data collection will be carried out from February 1, 2023 to December 31, 2023. The descriptive analysis will focus on the kinetics of all the variables measured and calculated on subgroups defined a priori on age, sex, comorbidities, acute covid severity, persistent symptoms post covid, regular habitual physical activity level, etc. according to the sample. The study is expected to collect data from around 1000 patients and to involve around 40 French-speaking investigators. However, this collaborative study is open on request to all centers wishing to participate, as the web platform has been developed for data collection in English.
The global population is aging at an unprecedented rate, increasing the necessity for effective interventions targeting the mental health needs of older adults. Virtual reality (VR) is a type of technology with the potential to improve mental health and well-being that allows users, via electronic devices such as headsets or goggles, to interact within simulated environments. VR programs using nature, mindfulness-meditation, and compassion may be more immersive and engaging, with research showing that these programs are effective at improving mental health and well-being outcomes in younger adults. However, evidence in this area for older adults is currently lacking. The present project intends to pilot and examine a multi-user 360-High Definition (HD) video VR application, called "Toujours Dimanche", developed in partnership with Super Sublime, a Montreal-based not-for-profit company. This VR application aims to support older adults through incorporating elements of nature, mindfulness-meditation, and compassion via a 4-week program of twice weekly, 10 to 20-minute meditation sessions, for a total of 8 sessions. Thus, this study seeks to pilot, revise and iteratively evaluate, via randomized control trial (RCT) methodology, the acceptability, feasibility, and effectiveness of a multi-user 360-HD video VR application (Toujours Dimanche) at improving older adult mental health and well-being. It is hypothesized that engagement with the 4-week VR-Meditation intervention will lead to lower scores on stress and negative affect and improved scores on well-being, positive affect, and mindfulness, in addition to increased scores on coping self-efficacy, connection with nature, embodied mindfulness, and self-compassion, over time and as compared to the active control group (who will receive psycho-educational pamphlets 1x/week for 4 weeks).
The research aims to characterize changes in ovarian and pituitary hormones associated with the development of ovarian follicular waves during the human menstrual cycle.
This is a pilot sub-study of an ongoing trial comparing N2O to midazolam in MDD and will examine neuroimaging correlates of treatment response.
