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.
Liver transplantation is the only treatment for end-stage liver disease. It is a high-risk surgery that can cause heavy intraoperative bleeding. Bleeding and transfusions of blood products are themselves associated with several postoperative complications. Few data have suggested beneficial interventions that can decrease this bleeding. Such interventions are necessary in order to improve these patients' outcomes. In order to better understand the potential therapeutic targets, a better comprehension of the variables associated with such bleeding is essential. Several previous studies have demonstrated a weak association between usual clotting times and bleeding in this population. However, few studies have evaluated the association between the concentration of fibrinogen and bleeding in this population. The primary objective of this study is to assess the association between preoperative serum fibrinogen concentration and the volume of intraoperative bleeding. The secondary objective is to assess the association between preoperative serum fibrinogen concentration and the number of red blood cell units transfused during the intraoperative and immediate postoperative periods. The hypothesis of the study is that a low concentration of preoperative fibrinogen will be associated with an increase in intraoperative bleeding and red blood cell transfusions.
People with inflammatory bowel diseases (IBD) can be at higher risk of developing abnormal areas in their bowel. These abnormal areas can be due to active inflammation, healed inflammation, polyps or pre-cancerous changes ("dysplasia"). It is for this reason that people with IBD are offered periodic surveillance colonoscopy procedures to identify, characterize and where necessary remove abnormal areas or lesions from the bowel. These can be difficult to characterize correctly, which is important to make the correct endoscopic diagnosis and management plan. Technical advancements in endoscopy mean that more tools are available to identify and characterize these lesions in real time during colonoscopy. Specialists regularly performing gastrointestinal endoscopy and colonoscopy ("endoscopists") will often receive special training, both during their initial postgraduate training and through continuous professional development programs. This study aims to evaluate whether an online training platform can improve the ability of endoscopists to characterize dysplasia in IBD. The goal is to support improved decision-making during IBD surveillance, reporting of dysplastic lesions, and ultimately the care and outcomes of people with IBD.
This is a clinical study in adult participants with moderate to severe atopic dermatitis (AD). The purpose of the study is to test a new medicine (LEO 138559) given by injection to see if it works to treat AD and what the side effects are when compared with a placebo injection with no medical ingredient. The study will last up to 36 weeks for each participant. The study will include a treatment period of 16 weeks, during which the participants will receive the injections, followed by a period of 16 weeks without treatment with the main purpose of continuing safety evaluations. The participants will regularly visit the clinic for tests and the study doctor will evaluate their AD. The participants will also be asked to answer questions about their AD symptoms and quality of life.
The purpose of the study is to assess the efficacy and safety of ruxolitinib cream in children with Atopic Dermatitis. This is a randomized, double-blind, Vehicle Controlled study. Participants will be randomized 2:2:1 to blinded treatment with ruxolitinib cream 0.75% ,1.5% , or vehicle cream, with stratification by baseline IGA score and age. At Week 8, efficacy will be evaluated. Participants who complete Week 8 assessments with no additional safety concerns will continue into the 44-week Long Term Safety (LTS) period with the same treatment regimen, except those initially randomized to vehicle cream will be rerandomized (1:1) in a blinded manner to 1 of the 2 active treatment groups (ruxolitinib cream 0.75% or 1.5%).
Following acute pulmonary embolism (PE), up to a third of patients develop post-PE syndrome described as having persistent breathlessness (dyspnea), impaired exercise capacity, and a reduced quality of life. The post-PE syndrome includes patients with chronic thromboembolic pulmonary hypertension (CTEPH), patients with chronic thromboembolic disease (CTED) those with an obstruction of the pulmonary arteries without pulmonary hypertension, and patients with post-PE related dyspnea without obstruction or pulmonary hypertension. Although therapies exist for the most severe form of the post-PE syndrome (CTEPH) - for most patients there are no available disease specific therapies that reduce symptoms. Despite studies showing increased breathlessness and abnormal exercise responses in patients with CTED, a detailed examination of what causes breathlessness in post-PE syndrome has never been undertaken. It is suspected that reduced blood flow to the lungs contributes to the feelings of breathlessness, particularly during exercise. This study will use inhaled nitric oxide, a medication that increases blood flow to the lungs. Inhaled nitric oxide is used primarily in hospitalized patients in the intensive care unit with respiratory failure, its use in people with post-PE syndrome is experimental. The investigators believe use of this medication may help to relieve symptoms of breathlessness. In order to test this medication, in volunteers with post-PE syndrome, the following will be measured: 1) breathlessness, 2) the signal to breathe sent from the brain to the lungs, 3) the activity of the muscles involved with breathing and 4) the amount of different gasses in the blood during exercise. The investigators will compare breathlessness and exercise tolerance during exercise while receiving: 1) a placebo (normal medical grade air) and 2) inhaled nitric oxide (a medication that improves blood flow to the lungs). By comparing symptoms during these two conditions, it is hoped to obtain a better understanding of what causes breathlessness in people with post-PE syndrome. This clinical research study will recruit approximately 20 clinically stable participants with CTED or post-PE related breathlessness.
This study will look at how participants' daily life is affected by their heart failure. The study will also look at the change in participants' body weight. This study will compare the effect of semaglutide (a new medicine) compared to "dummy" medicine on body weight and heart failure symptoms. Participants will either get semaglutide or "dummy" medicine, which treatment participants get is decided by chance. Participants will need to take 1 injection once a week. The study medicine is injected with a thin needle in a skin fold in the stomach area, thigh or upper arm. During the study participants will have talks with the study staff about healthy lifestyle and physical activity. The study will last for about 59 weeks, that is a little more than 1 year. Participants will have 12 clinic visits with the study doctor. - At 6 of the visits participants will have blood samples taken. - At 5 of the visits participants will be asked to fill in a questionnaire - At 4 of the visits participants will have to do a 6-minute walking test - At 3 of the visits participants will have a test to check the heart. - participants will have their eyes checked before or at the start of the study and at the end of the study Women cannot take part if pregnant, breast-feeding or plan to become pregnant during the study period.
In order to assess the mother-to-infant and potential vertical transmission of SARS-CoV-2 infection in pregnant women, maternal and neonatal biological samples will be prospectively collected from women with confirmed or suspected COVID-19 at participating hospitals across Ontario. Samples will be tested for the SARS-CoV-2 serology and viral load. Outcomes for the study objective will be ascertained through the collection and testing of biological samples from the mother and/or infant. Specifically the investigators will: 1. Assess maternal nasopharyngeal or oropharyngeal swab, vaginal mucosa, ano-rectal swab, amniotic fluid, placenta (including subamniotic swab), breastmilk, cord blood and neonatal nasopharyngeal swab for RNA particles of coronavirus, by ddPCR. 2. Assess maternal serum for anti-coronavirus antibodies, by immunoassay. 3. Examine the impact of coronavirus on the neonate with respect to serology and viral load, in addition to placenta pathology findings and ddPCR. 4. Assess vertical transmission and the effect of coronavirus through placental pathology examination using placental pathology synoptic report.
Postpartum depression (PPD) affects up to one in five of women and has profound effects on mothers and their infants. Unfortunately, fewer than 15% of women with PPD receive evidence-based care. This is at least partly due to significant difficulties faced by women in accessing psychotherapies, their preferred treatment for PPD. Around the world, there is a significant lack of healthcare professionals trained to deliver CBT. This study will utilize a randomized controlled trial design (with wait-list controls) and recruit 174 participants to determine if women with a past history of PPD (i.e., lay peers) can be trained to deliver effective group CBT online to women currently struggling with PPD. If peers can be trained to provide effective CBT, more women would receive treatment and the burden of PPD on women, families, and the healthcare system would be significantly reduced.
The purpose of this study is to investigate the safety, pharmacokinetic profile, and effects of nicotinamide mononucleotide (NMN-C) in healthy adults, 18-65 years of age. The effects will be studied over the course of 30 days in a repeated-dose study through the collection of blood and urine samples, and administration of surveys and questionnaires.
A pre-/post-test design. Youth with type 1 diabetes and their parent(s) were referred to the intervention by their diabetes physician. Decision coaching guided youth and their parents in completing a patient decision aid that was pre-populated with evidence on insulin delivery options. Primary outcomes were youth and parent scores on the low literary version of the Decisional Conflict Scale (DCS).
