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 will include patients with invasive cervical cancer that wish to keep their fertility as much as possible in the future after treatment. Patients who receive surgery alone may experience long-term side effects including infertility. The purpose of this research study is to determine whether giving neo-adjuvant chemotherapy prior to surgery can maintain fertility in patients with invasive cervical cancer. The neo-adjuvant chemotherapy will consist of a platinum-based chemotherapy drug cisplatin or carboplatin, with a chemotherapy drug called paclitaxel. These are common chemotherapy drugs used in the treatment of women with cervical cancers.
Post-market clinical follow-up for continued assessment of safety and performance of the InterStim basic evaluation lead and foramen needle(s) used during a therapy evaluation.
Compartment syndrome can result from extremity trauma. It can also be caused by procedural cases that involve lower or upper extremity surgery. This condition results in muscle death, chronic pain, infection, and possible amputation. Early diagnosis is essential to institute interventions that can avoid complications. Subjective pain of the patient remains the mainstay for diagnosis. A method or device is needed that would improve our accuracy in diagnosing compartment syndrome. Ideally, this would be suited for single and/or continuous pressure read-outs. The aim is to reduce the incidence of missed compartment syndrome and diminish delays that would lead to significant disability. Despite awareness, delayed diagnosis and treatment occurs in modern orthopaedic practice. As noted in many studies, once a diagnosis has been made, immediate fasciotomy is necessary to provide the best chance for a favourable clinical result. Therefore, there is a need for improved devices in order to obtain an early and reliable diagnosis.
The purpose of this study is to evaluate if folic acid improves endothelial sensitivity to shear stress in post-menopausal women.
Endoscopic Mucosal Resection (EMR) is the current standard for effective endoscopic resection of such colon adenomas. If resection is possible in one piece (so-called "en bloc" resection) then recurrence rates are low. However, most non-pedunculated polyps >2 cm are removed in pieces ("piece-meal" resection) which leads to disease recurrence rates between 12-30%. In the March 2019 issue of Gastroenterology Bourke et al. presented that post-EMR ablation of the resection margins using soft coagulation with the tip of a resection snare reduces adenoma recurrence to 5% compared to 21% recurrence found in the control group. Hybrid Argon Plasma Coagulation (h-APC) combines an ablation technique (APC) with the option for submucosal saline injection using a high-pressure water jet. The technique allows to lift of dysplastic epithelium thus creating a safety cushion under the mucosa is lifted with a saline injection and then to ablate larger areas more thoroughly and with a higher energy setting, with a low risk for side effects or complications.
The purpose of this study is to assess the strategy in treatment selection using ctDNA fraction as a predictive biomarker to direct treatment decision (ctDNA fraction <2% receives enzalutamide, and ctDNA fraction ≥2% receives docetaxel) versus clinician's choice of enzalutamide or docetaxel, in subjects with metastatic castration-resistant prostate cancer post abiraterone setting.
The primary objective is to provide dose-ranging data for 4 dose regimens of BI 655130 compared to placebo on the primary endpoint of percentage change from baseline in PPP ASI at Week 16. The target dose(s) will be estimated from the model by incorporating information on the minimum clinically relevant effect and accounting for safety. Supportive dose-ranging assessments will also be done on pre-specified secondary endpoints.
Postoperative analgesia for shoulder surgery is typically achieved by providing an interscalene brachial plexus block. However, a very common side effect of this block is hemi-diaphragmatic paralysis, a state which may not be tolerated in patients with pulmonary conditions such as COPD. Recently, clinicians have explored new ways to provide satisfactory analgesia while minimizing the pulmonary side effects of the interscalene nerve block. One of these solutions might be to offer the patient a suprascapular nerve block combined to a posterior cord block. Since these blocks are performed lower in the neck or under the clavicle, the phrenic nerve is less likely to be blocked. Thus, fewer respiratory side effects have been reported when using such blocks. This prospective observational study will evaluate the NOL response to surgical stimuli and the opioid requirements intraoperatively in patients undergoing shoulder arthroscopies with either a supraclavicular and posterior cord blocks or an interscalene block. Study Design: Prospective, randomized open label non-inferiority trial. Subject Population: Adults scheduled to undergo elective shoulder arthroscopy Sample Size: 100 patients Study Duration: Starts February 2019 - Ends February 2021 - Interim analysis at 50 patients Study Center: Maisonneuve-Rosemont Hospital, CEMTL, Montreal, Quebec, Canada
The purpose of this study is to evaluate the effectiveness and safety of IONIS-FB-LRx, an antisense inhibitor of complement factor B messenger ribonucleic acid (CFB mRNA), and to evaluate the effect of IONIS-FB-LRx on plasma factor B (FB) levels and serum AH50, CH50 activity in participants with primary immunoglobulin A (IgA) nephropathy.
Phosphate is present in many of the foods that the investigators eat and is required by many cellular processes. The kidneys are the only organ that excrete the extra phosphate from the diet that the body does not require. Phosphate is linked to vascular calcification and cardiovascular disease. Measures of serum phosphate do not reflect the burden of phosphate and are not sensitive to early changes in the way the kidneys eliminate phosphate. This study will determine whether the kidneys handle an oral phosphate load differently after 5 days of a low phosphate diet compared to 5 days of a high phosphate diet.
