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.
This study aims to determine the requirements for the sulphur amino acids in adults over the age of 60 years: 1. the total sulphur amino acid requirement as methionine only. Methionine is an essential amino acid. 2. the minimum methionine requirement as methionine in the presence of excess dietary cysteine. It is known that protein and amino acid metabolism may be altered with age and methionine and cysteine, in particular, may be important in the diet of older adults. Up to 7 different levels of methionine intake as methionine only (no dietary cysteine) and up to 7 different levels of methionine intake in the presence of excess dietary cysteine will be tested in each subject in random order. Each level of intake will involve a 3-day maintenance diet, with measures being collected on the third.

Determine that patients given intravenous tranexamic acid improves surgeon-rated visualization compared to placebo. 2. Determine that intravenous tranexamic acid is a safe alternative to epinephrine mixed irrigation fluid to improve arthroscopic shoulder visualization
Antibiotic overuse is common and antibiotic prescribing contributes to rising rates of antimicrobial resistance. Primary care physicians prescribe the majority of all antibiotics and there is large inter-physician variability in prescribing that cannot be explained by differences in patient populations. Peer comparison audit and feedback (A&F) can act as an effective behavioural intervention to reduce unnecessary antibiotic use. The range of effects seen in prior A&F trials could be attributed, at least in part, to differences in the way the feedback interventions were designed. In fall 2018, the investigators conducted an audit and feedback trial of mailed letters to 3500 family physicians in Ontario who prescribe the highest volume of antibiotics [NCT03776383]. While effective, family physicians questioned the credibility of the report in terms of its ability to fairly account for their practice size and population. In Ontario, A&F is routinely offered to primary care providers from a variety of sources. Ontario Health - an agency created by the Government of Ontario - provides A&F via email to physicians who voluntarily sign up for their "MyPractice" reports. These are multi-topic reports with aggregated (physician-level) data. As of November 2021, the MyPractice reports for family physicians will include data on antibiotic prescribing. To date, less than half of Ontario family physicians have signed up for the MyPractice reports from Ontario Health. For this study, the investigators will conduct a trial to investigate the effect of A&F in family physicians not already receiving A&F through a MyPractice: Primary Care report. Physicians who do not already receive antibiotic prescribing feedback through a MyPractice report will receive personalized antibiotic prescribing feedback through a letter mailed out from PHO. This large-scale evaluation provides an opportunity to evaluate not only whether A&F using such data is helpful in the post-covid context, but how best to design the A&F intervention and to explore why we observed (or not) changes in antibiotic prescribing.
Social isolation is defined as the objective and/or subjective reduction of number and quality of interpersonal contacts leading to a loss of an individual's social role and stigmatization. It is a major problem in Canadian society with a high prevalence in the older population (30% in individuals aged 65 and over, representing 1.5 million individuals). Social isolation is associated with a wide range of mental and physical health problems that leads to an increase in the use of health and social services. This issue increased with the coronavirus disease (COVID-19) pandemic which attacking your society at its core. Social distancing and in particular home confinement exacerbated social isolation of frailer groups like the elderly people. In 2016, the International Federation on Ageing reported that "the main new problem facing seniors in Canada is maintaining their social contacts and activities". This highlights the need for efficient and effective interventions to improve the social inclusion of older adults experiencing social isolation. Research suggests that art-based activities carried out at museums have significant benefits for older adults experiencing social isolation, and may foster social inclusion, well-being, quality of life and mitigate frailty. Yet few studies have examined empirically the effects of museum art-based activities in older adults experiencing social isolation. In 2019, the principal investigator of this research conducted an experimental pilot study based on a pre-post intervention (i.e., 3-month cycle of weekly guided tours carried out at the Montreal Museum of Fine Arts (MMFA)), single arm, prospective and longitudinal follow-up named "Effects of Montreal Museum of Fine Arts visits and older community dwellers with a precarious state: An experimental study", which indicated the potential of museum tours to improve social inclusion, well-being, the quality of life and frailty in older community members experiencing social isolation. However, these studies were performed before the COVID-19 crisis and were in-site activities. The principal investigator hypothesizes that a 3-month cycle of virtual weekly MMFA tours may induce changes in well-being, quality of life and health condition in older community dwellers participating like the 'Beautiful Thursday' cycle, and that this activity can prevent the worsening of vulnerability and social isolation due to social distancing.
The aim of this study is to appreciate, using quantitative and qualitative empirical methods, the contribution of an educational video game to the engagement, the motivation, and the development of nursing students' interpretation of acute heart failure patients' health condition. Two prototypes of the same educational video game have been developed. Study participants will play with both prototypes, complete online questionnaires and be interviewed by a research assistant regarding their experience with both prototypes. Study results will serve to select the most promising prototype between the two, based on its potential to support the engagement, the motivation, and the development of nursing students' interpretation of acute heart failure patients' health condition. Study results will also serve to refine the selected prototype before conducting a larger-scale efficacy trial. As such and given the small sample number of participants that is expected, it is not planned to conduct hypothesis testing.
This study is a Phase I/II clinical study in healthy adults designed to assess the safety, tolerability, and immunogenicity of receiving 2 IM injections of Covigenix VAX-001/-1b, 28 days apart. Covigenix VAX-001/-1b is a plasmid DNA vaccine that expresses key antigenic determinants from SARS-CoV-2 and uses Entos Pharmaceuticals' Fusogenix PLV platform. The phase I part of this study was completed in Canada. The phase II part of the study will be completed in Burkina Faso, Senegal and South Africa.
Ultrasounds are usually done by a specially trained health professional in the hospital or emergency department (ED) setting. Using a novel single-probe device, the ultrasound can be plugged into an iOS / Android device. The purpose of this research is to assess the usefulness of lung ultrasound imaging, performed by the patient in the home setting for the management of the COVID-19 disease using this novel highly-portable ultrasound.
In a worldwide context of accelerated demographic aging, traumatic brain injury (TBI) in older adults has become a public health problem. TBI incidence grows following an exponential curve as people get older, increasing the occurrence of TBI in ageing individuals. Rehabilitation programs used in clinical settings have generally been developed for younger adults, and their efficacy with older adults who sustain a TBI has not been evaluated. The investigators have tailored a modular cognitive rehabilitation program for individuals who sustain a TBI in older adulthood, the Cognitive Enrichment Program (CEP), by adapting approaches which have shown to be effective in normal ageing and with other neurological conditions. The aim of the study is to evaluate the effectiveness of the CEP in adults having sustained a TBI during later adulthood. Specific objectives are to evaluate the effectiveness on memory, executive functions, psychological well-being and daily life activities using psychometric tests, self-reported questionnaires, and daily life-like tasks. The investigators hypothesize that memory and executive functions training included in the CEP will result in an improvement in both psychometric and self-reported scores in a trained group of older individuals with TBI, whereas this will not be the case for a comparable TBI group who did not receive the CEP intervention.
This Phase 2b study aims to evaluate the efficacy and safety of adavosertib, an inhibitor of the tyrosine kinase WEE1, in subjects with recurrent or persistent uterine serous carcinoma (USC) who have previously received at least 1 prior platinum-based chemotherapy regimen for the management of USC.
This study will explore the effects of 8 weeks of local leg heat therapy, exercise training, or both on measures of vascular function, cardiorespiratory fitness, and muscle strength in young, healthy individuals. Participants will be allocated into either a control group that will maintain their regular physical activity habits; or into one of three training groups: heat therapy will involve lower limb warm water immersion, exercise training will involve moderate-intensity cycling, and combined training will involve both performed in sequential order.
