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.
Utilizing CellSearch® technology, the ability to both enumerate and reliably and reproducibly characterize circulating tumor cells (CTC) for tumor markers that predict endocrine sensitivity (estrogen receptor [ER] and Bcl-2) and resistance (HER2 and Ki67) has been demonstrated. An algorithm for a CTC-Endocrine Therapy Index (CTC-ETI) has been constructed that can be calculated for each patient using the CTC enumeration and marker results. The primary goal of this study is to determine a CTC-ETI in ER positive, HER2 negative metastatic breast cancer patients before the initiation of a new endocrine therapy for the identification of patients that will progress rapidly.
This study will examine whether measurement of pelvic floor muscle sEMG activity is responsive to explicit sexual stimuli, and whether it correlates with self-reports of sexual arousal in healthy women. Participants' vaginal, labial and anal sEMG readings will be monitored during exposure to neutral, erotic and anxiety-provoking films. Participants will also be required to provide subjective ratings of sexual arousal before and after each film. If pelvic floor sEMG is validated as a psychophysiological measure, these findings may have important clinical and research implications by providing a greater understanding of the mechanisms involved in sexual arousal and for providing a relatively easy method of assessing sexual arousal in a clinical or research setting.
The objective of the present study is to use positron emission tomography brain imaging to investigate D3 occupancy of buspirone, an FDA-approved anxiolytic which acts as a serotonin partial agonist but has recently been identified as a D3 antagonist. It is hypothesized that clinically relevant doses of buspirone will occupy the D3 receptor.
Exposure to allergens changes the way the airway responds to some stimuli (methacholine). The investigators will look at whether or not exposure to allergens changes the way the airway responds to a different stimuli (mannitol) and compare that with the known stimuli (methacholine).
This experiment is designed to test the hypothesis that oxidative stress is responsible for changes in airway responsiveness in humans exposed to diesel exhaust.
The study is a Phase-I like double blind randomized placebo controlled crossover design trial. The objective is to assess the dose response relationship on glycemic and vascular effects of an acutely administered Korean White Ginseng (KWG)(Panax C.A. Meyer) in individuals with metabolic syndrome or type 2 diabetes . Twenty seven subjects with Type 2 Diabetes (Key inclusion criteria: HbA1c ≤8.5%)or metabolic syndrome (Key inclusion criteria: as defined by The US National Cholesterol Education Program Adult Treatment Panel III)will be recruited for the study.
No one knows how long bupivacaine finger blocks last. Many use bupivacaine with and without epinephrine, but no one knows how the epinephrine affects the duration of the block. We also don't know how long the pain part of the block lasts, which is what counts. The goal of the study is to determine the duration of action of bupivacaine digital nerve blocks (with and without epinephrine) on finger temperature and the sensory modalities of pain, touch, and pressure. 2 ml of bupivacaine 0.5% with and without epinephrine will be injected at the base of each ring finger on the palm surface. At the end of 1 hr, 6 hrs, 12 hrs, 14 hrs and each additional hour, patients will use an insulin lancet to measure pain, the Semmes Weinstein monofilament test to measure light touch and pressure and a body surface thermometer to measure finger temperature. The time for the finger to return to normal sensation and temperature will be measured.
Falls and fractures are a leading cause of death and disability in the older adult population. The consequences of falls and fractures contribute substantially to health care costs and can have a significant negative impact on the quality of life of the individual. Exercise has been studied as an option to reduce fracture risk and prevent falls though improving balance and muscle strength. The prevention of falls is important, as a history of falls is strongly predictive of suffering another. Those who are at a high risk of fracture or falling require a patient specific assessment and individualized exercise prescription that is tailored to their needs. This kind of program may not be typically available within the community and at a low cost. These individuals may experience difficulty when trying to engage in exercise due to barriers such as a lack of transportation, and a lack of knowledge. As the first point of contact with the health care system for many family doctors are in the ideal position to deliver exercise advice to their patients. However, a lack of time and specialized skills in prescribing exercise make this difficult for many of them. As a result, family health teams who provide interdisciplinary patient centered care are becoming popular. In this model the care is shared and provided by the most appropriate team member (e.g. doctor, nurse, exercise specialist). Additionally, many exercise interventions do not include a behavior change aspect, which may be an important component when trying to get individuals to engage in a new health behavior like exercise. Therefore the purpose of this project is to assess the feasibility of implementing a tailored exercise program to those at high risk of falls or fractures over the age of 65 in a primary care setting using an interdisciplinary model of care that is based on a health behaviour change model.
This study will test the effectiveness of negative pressure wound therapy (using the VAC Prevena device, KCI Canada Inc.) applied to the saphenous vein harvest site after Coronary Artery Bypass Grafting (CABG). When initiated immediately after surgery, this intervention may decrease the incidence of wound infection and non-infectious wound complications. It may decrease wound discomfort and improve mobility and functional recovery of the leg.
Assess if the implementation of an enhanced treatment algorithm will improve the management Crohn's Disease compared to a conventional Step-care approach.
