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.
Solid food or fluid residue in the stomach is always a major concern when patients need medical procedures under sedation or general anesthesia, due to the high risk of pulmonary aspiration of the stomach contents. This is especially important in emergency procedures, when a fasting period is not observed. The aspiration of the stomach contents into one's lungs can lead to serious complications (such as severe respiratory failure). Information from a bedside ultrasound assessment of the stomach may be a very useful tool to decide whether or not it's safe to proceed, cancel or delay a surgical procedure. The investigotrs hypothesize that a mathematical model can be constructed to predict clear fluid volume in the stomach of non-labouring pregnant patients, as it has been developed in healthy adult volunteers.
The incidence of type 2 diabetes mellitus (T2DM) is increasing rapidly. The combination of T2DM and smoking is particularly lethal, as smokers with T2DM are significantly more likely to develop a number of health related complications. Community-based diabetes education programs (DEPs) have been developed to support patient self-care behaviours (e.g. adherence to oral medications, insulin therapy, nutrition management, regular blood glucose monitoring, and physical activity); however, specific assistance for smoking cessation is rarely provided. Our investigative team has developed a knowledge transfer and practice change process to introduce evidence-based interventions for smoking cessation into clinical practice settings. This process is known as the Ottawa Model for Smoking Cessation (OMSC). Investigators believe there is an opportunity to use the OMSC intervention to dramatically enhance the effectiveness of DEPs in addressing smoking cessation among smokers with T2DM, and in so doing, improve quit rates in this high risk population. The purpose of this project is to evaluate the effectiveness of the Ottawa Model for Smoking Cessation (OMSC) intervention in multiple diabetes education programs (DEPs) in Ontario. A two-level recruitment strategy will be employed. Eighteen DEPs will be recruited, and then a consecutive sample of eligible smoker-patients will be recruited from each DEP over a 6-month recruitment period. Investigators want to test the impact of the OMSC intervention on quit rates among smokers with diabetes and pre-diabetes referred to these programs. Investigators will conduct a matched-pair cluster design trial at 18 DEPs in Ontario. These sites will be matched based on number of annual referrals for diabetes education (≤ 500/year or > 500/year). Within each pair, sites will be allocated randomly to either OMSC intervention or control group. Following randomization, the OMSC program will be implemented at the intervention sites over a 6-month period. Following the implementation period, a consecutive sample of smokers will be recruited from both OMSC intervention and control DEPs over a 6-month recruitment period. It is estimated that this will yield a sample of approximately 445 smokers in each of the OMSC intervention and control groups. The primary outcome will be the biochemically-validated 7-day point prevalence abstinence rate six months after an index visit to the DEP. Secondary outcomes will include: rates of identification and intervention of smokers, and diabetes educators' attitudes, confidence, and perceptions of barriers and facilitators to implementing smoking cessation support as part of routine care. If proven effective, the OMSC is appropriate for implementation in DEPs across Canada and could have profound impacts on patient and community health.
School-based interventions are generally ineffective for preventing weight gain in children. In 2007, a group from the University of British Columbia, developed a program called Healthy Buddies, that relied on peer mentors to help young children adopt healthy living behaviours. Pilot studies revealed that the program effectively prevented weight gain in children. This trial had never been tested on a large scale using a more scientifically sound study design. We developed a large school-based randomized trial to overcome that limitation and test the hypothesis that that a school-based peer-led healthy living program would reduce adiposity and increase physical activity among children 6-12yrs old.
This is an 6 month multi-centre, prospective, randomized, placebo controlled, double blind clinical trial followed by conversion of each arm to active nintedanib for an additional 6 months comparing the effect of nintedanib 150mg bis in die (BID twice daily) on the progression of IPF measured by using High Resolution Computerized Tomography(HRCT), lung function, functional component (6MWT), biomarkers, and PRO component (PROs) with continued treatment and assessments for up to 18 months.

The GyneFix-Viz is a frameless copper intrauterine device (IUD) used for contraception. The GyneFix IUD has been marketed in Europe and Asia for about 10 years. The new anchor in the GyneFix IUD was designed to be more visible on ultrasound and this could improve safety by reducing failed insertions and perforations. We now need to know how easy it is for doctors to see and measure the distance of the anchor to the outside of the uterus. The purpose of this open, prospective, observational study is to assess the feasibility of measuring the distance from the serosa of the uterus to the anchor following insertion of the GyneFix-Viz and at follow-up 6-8 weeks later. Secondary objectives are to assess the ease and pain of insertion, the acceptability of the device to Canadian women and any complications. We will also compare expulsion rates in post-abortion and other women.
Cardiovascular disease (disease of the heart and blood vessels) is one of the leading causes of death in Canada. It also carries a financial burden on the Canadian economy with a yearly cost close to $21 billion divided between loss of productivity and healthcare costs. The majority of cardiovascular disease cases (90%) are caused by factors that can be controlled and modified. These factors include high blood pressure, high cholesterol, diabetes (high blood sugar), tobacco smoking, unhealthy diet, obesity, physical inactivity and high alcohol consumption. Such factors are very common and not very well controlled and so individuals who have any of these factors would be at risk of having cardiovascular disease. As such controlling these factors will reduce the risk of having cardiovascular disease and improve the individuals' quality of life. Pharmacists frequently work with patients and their family doctor to provide cardiovascular care. Having a pharmacist involved in cardiovascular care may help patients with cardiovascular disease or at risk of having the disease because they are more accessible and may have more opportunities to educate people about cardiovascular medications. This might lead to better prevention and control of cardiovascular disease. Purpose: The research study will assess if a community pharmacy cardiovascular risk reduction intervention can help reduce cardiovascular risk. Procedure: If the individual has an elevated blood pressure, cholesterol, blood sugar, waist circumference or body weight or is physically inactive, have an unhealthy diet, a smoker or taking medications for any of the previously mentioned conditions, the pharmacist will assess the cardiovascular disease risk [risk of having a cardiovascular event (e.g. heart attack or a stroke)] using a computer program. If the individual is at high risk s/he will be asked to take part in the study. If the individual agrees to take part in the study s/he will be randomly assigned to either the Usual Care Group or the Advanced Care Group. All participants have an equal chance of being assigned to either group. If assigned to the Usual Care Group, the individual will receive the care and services that would normally be provided by the pharmacist. At 3 months, the pharmacist will see the individual who will be offered the Advanced Care at that time. If assigned to the to Advanced Care Group, the individual will be asked to meet with the pharmacist every 3-4 weeks over a 3 month period. During these meetings, the pharmacist will conduct an assessment that may include blood pressure, waist circumference, height and weight measurements and talk to the individual about their cardiovascular risk and medications. The individual and the pharmacist will come up with a plan for how to try to lower his/her cardiovascular risk. The pharmacist will discuss this plan with their family doctor. The individual will be asked to conduct some laboratory tests before the 3 months visit; these tests may include HbA1c (a blood test to measure blood sugar control over the last 3 months) and cholesterol to assess the effect of the intervention on cardiovascular risk.
The Physical Functioning Inventory (PFI) is a standardized patient reported outcome measure that assesses preclinical disability. Preclinical disability is a functional state in which people are still able to complete daily living tasks (e.g., walking, bathing) but are changing the frequency or modifying the way that they complete the tasks. The investigators have done some preliminary research using the PFI as an online monitoring tool (Richardson 2012), but further study is required to examine its psychometric properties and its suitability for use as a primary outcome measure. This measurement study has been designed to identify the optimal number of items on the PFI and to determine the reliability, validity, and responsiveness of the PFI when administered to a sample of adults and older adults both with and without chronic conditions. This project will also allow us to evaluate the use of self-monitoring of physical function and the added value of rehabilitation professionals to support self-monitoring. Using the results of the PFI, the investigators aim to develop a "tailored" population-based rehabilitation self-management intervention delivered through a secure messaging system in the patient's electronic personal health record (myOSCAR) that focuses on the early detection and prevention of preclinical disability.
The primary objective of the study was to assess the efficacy of Dupilumab, compared to placebo, in adult patients with moderate-to-severe atopic dermatitis (AD).
Ultraviolet (UV) light is part of normal sunlight and has many effects on human skin and health. One of the harmful effects of long-term UV light exposure is that it can cause skin cancer. The mechanism by which UV light causes skin cancer is not entirely understood. One of the ways UV light causes cancer is by modifying DNA molecules in the cells of the skin. Another mechanism involved in cancer formation by UV light is immunosuppression. By this mechanism, UV light inactivates cells of the immune system of the skin. The immune cells are responsible for the detection and destruction of foreign substances and organisms such as bacterias and viruses but they also recognize and destroy cancer cells. UV light is known to prevent cells of the immune system to destroy cancer cells. In laboratory experiments, a medication called denosumab has been shown to diminish the inhibition of ultraviolet-induced suppression of skin immunity. In other words, this medication could block the effect of UV on cells of the immune system and might allow patients taking this drug to be better protected from skin cancer. The objective of this study is to test whether denosumab blocks the immunosuppressive effect of UVB light in healthy subjects. This study is divided into two stages. In the first stage, ten subjects (Cohort 1) will be sensitized to diphenylcyclopropenone (DPCP), a topical sensitizer commonly used for the treatment of alopecia areata and cutaneous warts. By reexposing the subjects to DPCP in incremental doses, dose-response levels of cutaneous hypersensitivity reactions in normal skin will be obtained. This will allow comparison of the normal levels of DPCP-induced cutaneous hypersensitivity (CHS) reaction in non UV-exposed skin (Cohort 1) to the CHS obtained from the two UVB-exposed experimental groups of Cohort 2. In the second stage of the study, 20 subjects (Cohort 2) will be exposed to an immunosuppressive dose of ultraviolet B (UVB) 24 hours prior to DPCP sensitization. This is expected to result in the abolition of CHS upon rechallenge with DPCP. In order to assess whether denosumab can reverse UVB-induced immunosuppression, the subjects will have previously been randomized to receive a single 1mL injection of either 60 mg denosumab (group A; 10 subjects) or 1 mL saline (group B; 10 subjects) two weeks before UVB exposure. CHS reactions elicited by DPCP rechallenge will be compared between the denosumab and saline groups.
