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.
Urinary tract infections are common in infants. Obtaining urine from pre-continent children can be difficult and time consuming. The method of collection must balance reliability, speed, low rate of contamination, and invasiveness. According to the American Academy of Pediatrics, midstream clean-catch urine is an acceptable method to diagnose urinary tract infections. However, it is impractical in pre-continent children. Recently, two quick, safe and effective methods have been reported in the literature: - The Quick-wee method: it consists in stimulating the suprapubic area with a cold and wet compress to obtain urines. - The bladder stimulation method : the child is held under the armpits with legs dangling and a physician taps the suprapubic area and massages lumbar area alternatively. However, advanced age, high weight, and level of discomfort during bladder stimulation were significantly associated with failure to obtain urines.
Marijuana use has increased since its legalization in Canada and many believe that it may help patients that are experiencing chronic pain. The investigators want to assess if patients who have used marijuana chronically will need more medication to control their pain after they have undergone orthopedic trauma surgery (ex. Hip, femur, humerus fractures etc.). In this study, the investigators will identify chronic marijuana users (ie. those using for 3 months or more) who are undergoing orthopedic trauma surgery to assess how much pain medication they need post-operatively and compare this with non-users. The investigators will also evaluate their pain scores, pain medication use and other complications that they may have during or after their surgeries, including any nausea/vomiting, heart or breathing problems.
Psoriatic arthritis (PsA) is a type of joint disease that can lead to severe joint damage and disability within the first few years of the disease. This is why early detection and treatment of the disease is essential to prevent serious joint damage and improve long-term outcomes in these patients. However, there is currently no reliable way to tell the difference between PsA and other types of joint disease. This makes it difficult to detect PsA early. Enthesitis is an inflammation of the area where muscle tendons and ligaments attach to bones. Enthesitis is a key feature in PsA and can be easily detected using ultrasonography. The aim of this research study is to develop a system to evaluate enthesitis using ultrasonography, which can be used as an effective tool in the early detection of PsA. This will help in providing patients with early treatment to prevent further joint damage.
The investigators hypothesize that the clinical implementation of a deep learning AI system is an optimal tool to monitor, audit and improve the detection and classification of polyps and other anatomical landmarks during colonoscopy. The objectives of this study are to generate preliminary data to evaluate the effectiveness of AI-assisted colonoscopy on: a) the rate of detection of adenomas; b) the automatic detection of the anatomical landmarks (i.e., ileocecal valve and appendiceal orifice).
The purpose of this study is to assess changes in intrahepatic hepatitis B surface antigen (HBsAg) between baseline and on-treatment liver biopsy in response to JNJ-3989-based combination treatment.
This study aims to determine if the body's needs for threonine (an amino acid which is an essential building block for protein) is different when assessed after 1, 3 or 6 days of adaptation to the level of threonine intake being studied.
Introduction: Prostate cancer (PCa) is the most commonly detected cancer in men and is the second leading cause of cancer death. Differences in race and ethnicity have been shown to have differences in PCa incidence, detection, and outcomes. Current prostate cancer screening involves prostatic specific antigen (PSA) which is a nonspecific protein marker (aka kallikrein) that can often leads to unnecessary biopsies (up to 74% benign biopsies) and clinical overdiagnosis (with up to 22% clinically insignificant cancer). Recently more sophisticated tests have been developed for PCa screening in the United States such as the Prostate Health Index (PHI) and the 4k (kallikrein) score, as well as clinical models that use information from the patient clinical history. However, these tests utilize limited serum protein assays and none of the established screening protocols utilize genetic variables to help account for the likely inherited risks as seen in different ethnicities. A recent Swedish, prospective, population-based study, published in the Lancet Oncology, developed a unique multivariable biopsy outcome prediction model within a Nordic population of nearly 60,000 men. This model, the Stockholm3, which incorporated plasma protein markers, germline DNA SNPs as well as clinical variables, was shown to be capable of reducing the number of biopsies by 44% compared to PSA while maintaining adequate sensitivity for detection of PCa. It is unknown whether an approach developed in Sweden that incorporates protein markers, genetics, clinical variables, and genetic ancestry would be beneficial in a racially diverse cohort. Hypothesis: The investigators hypothesize that, a prospectively studied multiethnic cohort of men with the Stockholm3 test will identify unique and common risk factors that improve prostate cancer detection. Aim: To assess the performance of the Stockholm3 test as compared to PSA and to identify unique features associated with PCa in Black/African American (n=500), Asian (n=500), White/Caucasian Hispanic (n=500), and White/Caucasian Non-Hispanic (n=500) men. Methods: The investigators propose a prospectively identified cohort with participating institutions which have screened positive to undergo a prostate biopsy to have a retrospective analysis the Stockholm3 test and ancestry markers. Within this cohort the investigators will examine several predetermined risk factors to investigate their relationship to prostate cancer. This blood sample will be tested for quantitative levels of serum protein markers and DNA will be extracted and will be tested for germline mutations as defined by the Stockholm3 test and other ancestry informative markers. Results from the study will be presented in such a way that no individual information will be disclosed.
Our previous pilot study (N = 40) suggested that group Cognitive Behaviour Therapy for perinatal anxiety (CBT-PA) significantly reduces symptoms of anxiety and depression from pre- to post- intervention. CBT-PA is based on the general principles of CBT but specific themes and examples are geared towards pregnancy and postpartum periods. The 6-week treatment protocol addresses: (1) understanding anxiety during pregnancy and postpartum, (2) self-care, (3) setting goals and facing fears, (4) nurturing the developing relationship with baby, (5) coping with negative thoughts and worries, and (6) relapse prevention. This intervention and all assessment interviews will be conducted via a hospital-approved video-conferencing platform. All assessment questionnaires will be completed on SurveyGizmo. The objectives of the present study are: (1) to replicate these findings of the pilot study in a larger sample (N = 58) in a randomized controlled trial (RCT), (2) compare the effectiveness of CBT-PA to a control treatment (waitlist control), (3) evaluate the durability of treatment gains at 1-month and 3-months after the conclusion of treatment, (4) evaluate patient preferences in terms of the relevance and the acceptability of the CBT-PA protocol, (5) examine whether the degree of childbirth stress impacts patient response to CBT-PA to inform future refinements to the treatment, and (6) determine whether CBT-PA improves maternal efficacy and attachment with baby. This research is being conducted because many women suffer from perinatal anxiety and have difficulty accessing services in a timely manner. It is the hope that the findings of this study will have clinical significance in terms of providing additional support for CBT as an effective treatment for perinatal anxiety. It is the hope that this treatment will have mental and physical health benefits for the mothers directly, as well as mental and physical health benefits to their fetuses and infants.
General anesthesia induces hemodynamic changes, notably a reduction of arterial blood pressure going up to 30%, that may impact cerebral perfusion and oxygenation.The purpose of this study is to assess the impact of anesthesia on the cerebral oxygenation, the perfusion of the brain (assessed with transcranial doppler), and the depth of anesthesia in children between 6 months and 5 years old during the induction of general anesthesia (induced with sevoflurane and/or IV agents). It is expected that the cerebral hemodynamic will be maintained despite systemic variations.
