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 this study to evaluate the efficacy of ravulizumab compared with placebo to reduce proteinuria and slow the rate of eGFR decline in adult participants with IgAN who are at risk of disease progression.
This study aims to evaluate esmolol's perfusion impact during induction and maintenance of general anesthesia, using Nociception-Level-guided control of nociception, in adult patients undergoing laparoscopic and lower abdominal surgery, on intraoperative remifentanil consumption and postoperative pain in the Post-Anesthesia Care Unit.
The goal of this multicentre prospective observational cohort study is to shed light on the following unknowns: 1. The clinical manifestations of Mpox infection since the 2022 outbreak in Canada. 2. The social and psychological impacts of Mpox infection since the 2022 outbreak in Canada 3. The transmissibility of Mpox infection 4. Viral shedding over time in infected individuals The study is divided into Part 1 (corresponding to the acute phase of illness) and Part 2 (corresponding to the convalescent phase of the illness); part 2 will be optional. Participants enrolled during the acute phase of illness will complete part 1 of the study and will be invited to participate in Part 2 as well. Part 1 of the study will include the following three core components, at baseline and weekly (±3 days) until one week after the resolution of all symptoms (i.e. one week after complete healing of skin lesions): 1. Collection of clinical data through chart review and research staff interviews with study participants 2. Participant self-administered online questionnaires at baseline and a thrice-weekly 'acute phase participant diary' 3. Specimen collection for Mpox-related testing Optional components for Part 1 include baseline-only, questionnaire-only, and frequent sampling. Other optional components for all participants include in the Image Atlas, an online database of clinical images of mpox, designed to provide clinicians and community members of what mpox looks like in real life, and the biobank, which will store research samples for potential future studies.
Poor responders in in-vitro fertilization (IVF) cycles represent a major challenge for fertility specialists. Although poor responders tend to have sub-optimal fertility treatment outcomes, many of these patients wish to attempt at least one IVF cycle. Traditionally, IVF cycles producing less than 3 to 4 mature follicles (measuring at least 14 mm) have either been cancelled or converted to intra-uterine insemination (IUI) due to the low pregnancy rates associated with these cycles. The minimal number of follicles required to proceed with egg collection is based on clinical experience, having been determined by weighing the probability of implantation and pregnancy versus the risk of not obtaining quality oocytes or reaching embryo transfer when fewer mature follicles are present. This retrospective quality control study aims to compare pregnancy rates in IVF cycles producing 3 follicles measuring 14 mm and more on trigger day, versus 2 or fewer follicles.
Studies reported that calcium signal deficiency or insufficiency during oocyte activation are related with embryo arrest and blastocyst quality. The utilization of Artificial Oocyte Activation (AOA) is safe and does not increase birth defects, cognition, language and motor skills. AOA is the first line of treatment in patients with globozoospermia (round headed spermatozoa). Poor responders in in-vitro fertilization (IVF) cycles represent a major challenge for fertility specialists and comprises about 10-15% of patients undergoing controlled ovarian hyperstimulation. The absence of synergy between the oocyte and sperm leads to a negative impact on oocyte activation. The European Society of Human and REproduction (ESHRE) recommends AOA in cases with failed fertilization/ low fertilization.
Breathlessness is a common problem for many patients with Interstitial lung disease (ILD). ILD is a group of lung diseases that cause inflammation (swelling) and scarring in the lung tissue where gas exchange (oxygen and carbon dioxide) occurs. Unfortunately, there is no cure for these conditions and as a result many patients decline over time with worsening breathlessness. This limits their ability to live a good life. Clinicians do not often recognize, assess, or treat breathlessness appropriately. Breathlessness, being a subjective experience, cannot be fully understood through objective measurements such as lung function tests, the arterial blood gas test etc. The objective and subjective measures of breathlessness are frequently disconnected. Clinicians who often rely on these types of objective tests do not directly enquire into its nature and severity of breathlessness from patients themselves. As a result, they remain unaware of this disabling symptom and the extent of its impact on patients. While there are many tools to measure breathlessness, they are not consistently used in routine care or have impacted care in a meaningful way. Many such tools are also complex with intricate response systems with possibility of errors and user fatigue. As a result, easy to use tools like modified MRC or MRC are frequently used even though they do not assess severity of breathlessness. No tool has been effective at helping clinicians identify the problem and prescribe appropriate treatments. This results in needless suffering for patients and their families and prevents them from receiving timely and appropriate therapies. Investigators propose to test an easy-to-use tool that combines the subjective and objective aspects of breathlessness. Investigators hope that the tool will help clinicians quickly identify the patient's breathlessness severity and provide them with an algorithm of what to do next. The tool was developed by clinicians with +15 years of experience in ILD and dyspnea. Early analysis already suggests the tool is useful to patients and helps improve care.
This study will look at how CagriSema affects the blood levels of atorvastatin and warfarin. The study will look at the levels of warfarin and atorvastatin in the blood before the participant starts taking CagriSema and if this changes after the participant has taken CagriSema. The study will also investigate the effect of warfarin before and after the participant takes CagriSema and assess if the injection site affects the level of CagriSema in the blood. The study will last for about 8 months.
Despite improvements in treatments, head and neck cancer survivors (HNCS) still endure acute and chronic side effects such as loss of muscular strength, limitations in physical functioning, fatigue, and swallowing difficulties that impact quality of life (QoL) and limit return to work. Light-to-moderate intensity strength training (LMST) has been shown to improve some side effects. Heavy lifting strength training (HLST) may further improve outcomes in some populations, however, only one small pilot study has focused on HNCS. The LIFTING 2 trial will be the first to examine the feasibility and effects of a HLST program versus no exercise in HNCS.
The goal of this observational study is to determine if nerve transfer surgeries improve upper extremity function and quality of life in patients with a high level cervical spinal cord injury. Participants will: - undergo standard of care pre- and post-op testing and study exams - complete pre- and post-questionnaires - undergo standard of care nerve transfer surgeries - follow-up with surgeon at 6/12/18/24/36 and potentially at 48 months - attend therapy at local therapist for up to 2 years postop.
The goal of this clinical trial is to compare breath samples from patients with lung cancer, those with stable lung nodules, and individuals without lung cancer. The main questions it aims to answer are whether breath patterns are different in these groups and to see if breath patterns change after treatment in patients with lung cancer. Participants will be asked to provide one breath sample, and two if they get treated. They will also be asked to fill out a questionnaire about their background and medical history.
