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 determine the effectiveness of transcranial direct current stimulation (tDCS) plus nicotine patch as a viable smoking cessation program for nicotine dependent smokers.
Adult patients presenting to the emergency department with superficial cutaneous abscesses will be randomized after incision and drainage to standard care with wound packing or no packing to determine if there is a difference in the proportion of complications between the two groups.
Canadian Rheumatologists will be randomized to treat their participants with active Psoriatic Arthritis to a target (disease activity score <2.6), or as per their routine care. The aim of this study is to determine whether treating to a target results in greater disease improvement than treating patients using routine care.
Cancer patients with very difficult to control symptoms at the Abbotsford (AC) and Fraser Valley (FVC) Cancer Centers are referred and admitted to the Tertiary Palliative Care Units at the Abbotsford Regional Hospital and Cancer Center(ARHCC). For symptom management, patients are sometimes given midazolam continuously through a needle placed underneath the skin. While effective in symptom management, midazolam can be sedating, leaving patients unable to interact with loved ones in their last days. This study is a pilot project. Before proceeding to a full-scale study, a "pilot study" or "feasibility study" is often carried out first to test the design of a study, the likelihood of successful recruitment or the acceptability of the intervention to potential subjects. The basic idea is to find out whether it will be practical to proceed to a larger study that will include more subjects. This type of study involves only a small number of subjects and therefore the results can only be used as a guide for further larger studies. The investigators also will determine whether palliative care cancer patients taking a medication called dexmedetomidine would have improved rousability (more easily and fully awakened) and symptom control (pain, shortness of breath, nausea or confusion) compared with those taking standard of care which is receiving the medication midazolam. The use of dexmedetomidine in other clinical situations (in the Operating Room or Intensive Care Unit where the patient can still respond to the doctor) has been shown to be effective in symptom control and to provide a better degree of rousability to patients but has not been well studied in the palliative care environment.
The success of in vitro fertilization is based mainly on uterine implantation embryo. An excessive uterine contractility may interfere with implantation by a movement of the embryo in the uterus. The inhibition of the uterine contractility may have a positive effect on success rate of in vitro fertilization. It is through parenteral injection of glucagon and its spasmolytic effect on various smooth muscles and thereby on the uterine muscle, at the time of embryo transfer, the investigators intend to improve the pregnancy rates obtained after IVF.
Obstructive sleep apnea (OSA) in children is a disorder of breathing during sleep characterized by prolonged partial upper airway obstruction and/or intermittent complete obstruction (obstructive apnea) that disrupts normal breathing during sleep1. The condition occurs in 2-5% of children and can occur at any age, but it is most common in children between the ages of 2 to 62,3. Untreated OSA is associated with lung disease, heart disease, growth delay, poor learning and behavioral problems such as inattention and hyperactivity. The most common underlying risk factor for the development of OSA is enlargement of tonsils and adenoids. Given the potential risk of complications associated with surgery of the tonsils and adenoids, medications to shrink the adenoids without requiring surgery have been considered, in particular intranasal corticosteroids (INCSs) which is a nose spray. A recent Cochrane systematic review suggested a short-term benefit of INCSs in children with mild to moderate OSA4. The authors recommended that further randomised controlled studies were required to evaluate the efficacy of INCSs in children with OSA. In particular they recommended that future studies should employ sleep studies to look for any improvement with INCSs, and should include children with more severe OSA, as these are the patients at the greatest risk of complications of surgery and would benefit most from a non-surgical treatment. The purpose of this study is therefore to explore the efficacy of INCSs in children with the full spectrum of OSA severity, including sleep study analysis., and longer term follow-up.
The processing of standard flexible nasopharyngoscopes is a time-consuming and costly process. The goal of this study is to determine the efficiency and cost-effectiveness of sheathed flexible endoscope in an office setting.
More than 2 million patients in North America are treated with warfarin - a "blood thinner" - to prevent blood clots in arteries or veins. The treatment has to be monitored with a blood test and the dose changed accordingly every 1-4 weeks. One third of the patients have very stable results and hardly ever have to change the dose. The investigators wish to show that the level of control of the treatment with warfarin in these very stable patients is not worse with 12-weekly testing. A pilot study the investigators performed indicated that 12-weekly testing would be safe but this has to be confirmed in a large study. One third of patients taking warfarin have not had any changes in the dose for the past 6 months or longer. These patients will be asked about participation in the study. They will be randomized to testing and dosing every 4 or 12 weeks. Each patient is in the study until it ends, which will be minimum 1 year and can be up to about 4 years. The study is designed to show that 12-weekly testing does not significantly increase the risk for major bleeding or blood clots. The results would be important for a large number of patients. An increase of the interval between blood tests from 4 to 12 weeks would reduce the burden for these patients on life-long treatment considerably.
Phase II study designed to evaluate the safety and efficacy of BIIB057 in Subjects with Rheumatoid Arthritis who have experienced an Inadequate Response to Disease-Modifying Antirheumatic Drugs (DMARDs).
Chronic wounds cause significant morbidity and cost our healthcare system millions of dollars each year.Their healing is slowed by biofilms, communities of bacteria surrounded by a protective layer that stops the immune system and antibiotics from getting close enough to kill them. The investigators will develop a new strategy to destroy biofilms using a protein made from bacteria that live on our skin.The Staphylococcus epidermidis Esp protein will be used to destroy Staphylococcus aureus biofilms, the most common bacterium in chronic wounds. The investigators hypothesize that the use of the Esp protein will breakdown S. aureus biofilms, decrease bacterial colonization of chronic wounds and improve healing times.
