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 purpose of this study is to compare the effects of the radiofrequency applied to the sensory innervation of the knee, with respect to a control group (standard therapy), in a prehabilitation program aiming to improve the functional recovery of patients undergoing TKA. In the present study, the investigators hypothesize that participants treated with radiofrequency 4-6 weeks before the surgery, should be able to effectively accomplish the prehabilitation program and, therefore, have a faster recovery of their functional status in the post operative period , compared with the control group (That use the present state of the art approach)
To demonstrate the safety and feasibility of the Mercury Expander system and procedure to treat patients with lower urinary tract symptoms (LUTS) secondary to urinary outflow obstruction from benign prostatic hyperplasia.
The effects of food additives on body weight in humans are largely unknown. This is a before-and-after feasibility study in 5 obese adults who will be followed for 5 months. Eligible participants will meet with the study team and will be taught how to limit the exposure to the studied food additives in their diet. Participants will also be asked to limit eating out to a maximum of 2 days per week. Primary outcomes in this study are recruitment rate, retention rate and adherence to the proposed dietary intervention.
This study is being done to test the FLIP device, a novel device developed and manufactured by Endra Life Sciences, located in Ann Arbor, Michigan. The purpose of the device is to measure the fat content of liver tissue to assist in the diagnosis of fatty liver disease. This feasibility study will involve 25 healthy volunteers having their liver imaged by traditional ultrasound and MRI methods as well as using the FLIP device. The data obtained by the FLIP will be compared with the data obtained by ultrasound and MRI in order to determine the effectiveness of the device. This is a preliminary study to see if the investigational device could eventually be used to image the liver alongside traditional ultrasound for discerning fat concentration.
The primary objective of this study was to evaluate the abuse potential of single doses of cebranopadol (GRT6005) relative to hydromorphone (immediate-release formulation [IR] and placebo in 48 non-dependent recreational opioid users. Secondary objectives were to evaluate the abuse potential of hydromorphone IR compared to placebo (trial validation), to evaluate the safety and tolerability of single doses of cebranopadol (200, 400, and 800 micrograms), and to evaluate pharmacokinetics (PK) of cebranopadol and optionally some of its metabolites.
Traditionally, periodontal gum surgery has been used as a method to gain access to inflamed periodontal pockets around teeth. The outcome of these surgeries, however, is not always successful as there can be recurrence of inflammation and disease. The objective of this study is to assess the effectiveness of antimicrobial photodynamic therapy as an adjunct to mechanical debridement of residual periodontal pockets in patients having undergone periodontal surgery. Pocket probing depth (PPD), clinical attachment level (CAL), bleeding on probing (BOP), and plaque index (PI) will be evaluated at all sites as measures of inflammation and disease resolution.
This study is designed to explore the expression of cell-surface markers in the following seven disease areas: (a) systemic lupus erythematosus, (b) Sjogren's syndrome, (c) multiple sclerosis, (d) systemic sclerosis, (e) Crohn's disease, (f) ulcerative colitis and (g) inflammatory myositis.
False diagnosis of penicillin allergy are frequently reported, and have been proven detrimental to patients. Current guidelines for the assessment of drug allergies recommend that penicillin allergy be evaluated first with prick and intradermal skin tests, and then completed with a graded oral challenge, spread over at least two doses. However, it has been shown that these skin tests, in addition to consuming resources and time, are of limited, or even doubtful validity, given the poor predictive values that have been reported in the modern penicillins era. It now seems unreasonable to continue their use without addressing other, more efficient diagnostic stategies. Several groups have now demonstrated the safety, validity, and efficiency of a direct, two-step amoxicillin oral challenge (starting with 10% of the standard therapeutic dose, followed by 90 % of the dose), without prior skin tests, first for any type of reaction in the pediatric population, then for any non-immediate reaction in the adult population. The objective of this study is to demonstrate the safety, efficiency, and validity of direct, two-step graded oral challenge with amoxicillin for the evaluation of any reported penicillin allergy in the adult population, excluding high-risk patients (documented anaphylaxis to a penicillin in the last 5 years). Skin tests will first be performed according to the protocol currently in use at the CHUL, then consented patients will proceed with the graded oral challenge still according to the protocol currently in use at the CHUL, but regardless of the skin tests results. The results of the two tests will be compared to determine the safety, efficiency and validity of proceeding directly to the graded oral challenge.
Low back pain (LBP) is the leading contributor to years lived with disability and an important contributor to healthcare costs and time off work. Exercise is effective for chronic low back pain, but there is a lack of evidence to inform whether exercise in the emergency department is effective for people with acute low back pain. This randomized controlled trial will evaluate the effectiveness of a brief exercise intervention provided in the emergency department for people with recent onset low back pain. People with acute low back pain (<1 week) will be randomly assigned to either usual care or to usual care plus a brief exercise intervention delivered by trained physiotherapy students. The study will evaluate the impact of the added exercises on self-reported disability (primary outcome), pain intensity, global rating of change, patient satisfaction, and adverse events. In addition, we will pilot data collection related to return to work, healthcare utilization, and cost effectiveness outcomes to determine the feasibility of conducting a future trial with additional patient participants required to evaluate these outcomes. Outcomes will be evaluated at baseline, 48-72 hours, 1-week, 1-month, and 3-months from their initial emergency department visit. The results of this study have the potential to inform emergency department management of acute low back pain.
This study evaluates the benefit of Neuro 1 sound processor upgrade in speech perfomance in adults. Half of participants will be tested with Neuro 1 first and Neuro 2, while the other half will be tested with Neuro 2 first and then Neuro 1.
