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 is designed to study DNA sequencings for mutations in a research genetic test panel of genes (which contains all 32 known and/or published genes associated with PCD). The study aims to show that about 70% of PCD patients have biallelic mutations in one of these genes. This project will enroll patients who have already had a clinical evaluation, and have clinical features consistent with PCD.
Introduction- Hospital acquired infections (HAI) are a major cause of morbidity and mortality and increase health care costs. Critically ill patients are particularly susceptible to these infections and have an even higher mortality. One intervention that has gained much interest in the medical literature for reducing infection rates and deaths from HAIs is selective decontamination of the digestive tract (SDD). SDD involves the application of antibiotic paste to the mouth, throat, stomach and a short course of intravenous antibiotics. The evidence supporting the use of SDD for saving lives and preventing infections is actually quite strong. However, health care professionals in many parts of the world have refrained from using SDD due to fears of the effects of overuse of antibiotics on the frequency of infections with resistant bacteria such as multi-resistant Gram negative organisms, MRSA and Clostridium difficile. SuDDICU is a cross-over, cluster randomised trial comparing the effect of using selective decontamination of the digestive tract (SDD) plus standard care, to standard care alone on hospital mortality in patients receiving mechanical ventilation in the intensive care unit (ICU). Secondary outcomes include an ecological assessment and a long-term health economic analysis.
The purpose of this study is to investigate whether mechanoreceptor sensitivity of the sole of the feet increases with increased foot temperature and how a heightened sensation may improve characteristics of balance control and gait. As an extension, the investigators also want to determine whether lower limb movement is an efficient activity of increasing foot temperature. There are several objectives of this study. The investigators want to determine the effect of active recovery (via lower limb movements) on increasing plantar temperature, determine the effect of increased plantar temperature on plantar sensation and determine the effect of increased plantar sensation on balance control and gait characteristics. Participants will be asked to complete various tasks under different conditions. Conditions include decreased feet temperature via ice bath emersion, baseline feet temperature (participant's normal temperature after a ten minute equilibration period), and increased feet temperature via active movement of the lower limb. Tasks include walking across the room, performing active movement of the lower limb and a 10 minute treadmill walk. Gait movement will be collected with a three-dimensional motion capture system (Optotrak) and force plates. Feet temperature and sensation information will be collected with a temperature probe (infrared) and monofilaments.
This phase II study will investigate the use of palonosetron in the efficacy of prophylaxis or rescue of single or multiple fraction radiation induced nausea and vomiting. This prospective study employs a parallel arm design, allowing for inclusion of patients with pre-existing nausea and vomiting versus no current nausea or vomiting. Eligible patients receiving radiotherapy known to have a low or moderate emetogenic risk will receive every other day dosing of 0.5 mg palonosetron for the length of treatment. Nausea, vomiting, use of rescue medication, and impact on quality of life will be monitored during and after radiation treatment completion.
The purpose of this study is to determine the influence of topical prostaglandin analog (PGA) medication on corneal biomechanical properties in patients undergoing PGA treatment for open-angle glaucoma.
This study is being done to test if adding vitamin D to cheese and yogurt products will help children further improve their vitamin D intake. All children will be given a six month supply of the milk products. One group will receive yogurt and cheese products already sold in stores, while the other group will receive yogurt and cheese products with added vitamin D. This will show if milk products with added vitamin D help maintain vitamin D intake and child health. The investigators are asking children 2 through 8 years old to participate. Children must not have any medical conditions that affect their bones or vitamin D levels. They must not be taking vitamin D supplements or medications that affect bone. This study will last for 6 months. The investigators expect 60 children from the Montreal area will participate in this study. Children will be randomly placed in one of the two study groups. There will be an equal number of children in each group. All groups will go through the exact same procedures during the study; the only difference between groups will be the amount of vitamin D in the milk products they will consume each day. Families will not know which group their child is in until the study is complete. Children will continue to drink their regular milk at home and the investigators will provide flavoured yogurts and cheese to eat every day for the entire 6 month study. Families will be given a fresh supply of the yogurt or cheese products every 4 weeks along with instructions. There are 3 study meetings for the parent and child to attend which take place at the Mary Emily Clinical Nutrition Research Unit. The clinic is located on the Macdonald Campus of McGill University in Ste. Anne-de-Bellevue, QC. The first visit is at the start of the study, the second is at the end of 3 months and the last visit is at the end of the 6 month study.
This is a prospective, interventional study aiming to assess the effectiveness of the Esophageal Cooling Device (ECD) as a temperature control modality in post cardiac arrest patients. In addition, observed adverse events during ECD use, ease-of-use, nurse satisfaction and patient outcomes will be examined.
Humidified High Flow Nasal Cannula (HHFNC) is a new modality of respiratory support for children with respiratory failure. Despite its extensive use in pediatric and adult population, the exact mechanism of work of HHFNC is not fully explained.The objective of the investigators' research project is to determine the relationship between the amount of airway pressure that can be delivered at specific flow levels of HHFNC. This information will allow the investigators to use HHFNC in a much more informed and safe manner.
The main objective of the study is to determine whether depth of anesthesia (DOA) monitoring such as Bispectral Index (BIS) and entropy are accurate in patients with neuro-psychological conditions such as Parkinson's disease by comparing these monitoring with standard clinical monitoring like heart rate, blood pressure and respiratory rate.
Hallux valgus can be defined as a progressive subluxation of the first metatarsophalangeal joint and lateral deviation of the hallux. This common foot condition is associated with altered gait patterns. Specifically reduced forward propulsion, leading to gait instability. Research has shown that foot problems and pain play a major role towards the contribution of falls in the adult population. There are currently two main interventions for the treatment of hallux valgus: surgery and orthotic prescription. There has not been a lot of research performed evaluating the effects of custom orthotic prescription on hallux valgus. Therefore, this study will investigate adults with moderate hallux valgus and the effects of orthotic intervention on the efficacy of forward propulsion during walking. It is hypothesized that implementation of an orthotic will lead to decreased foot pain, an increase in step length, an increase in the forward moment about the ankle and hallux, and a more medial center of pressure tracking through the great toe instead of the lesser metatarsals. This study will consist of 10 adults. The participant will go through three rounds of testing in the lab. The first session will consist of initial baseline testing in which each participant will be evaluated for severity of Hallux Valgus and range of motion of the first metatarsophalangeal joint. A foot casting will then be performed by a pedorthist and the participant will be set up with markers, so as to record motion while they perform 15 walking trials across a 10m runway with a force plate embedded in the middle whilst wearing standard footwear (no orthotic). The second lab session will consist of the standard footwear (no orthotic) walking as well as the addition of standard footwear with custom orthotic walking. The third session, after having worn the orthotic for two weeks, will repeat both conditions measured in the second lab session. Data about the center of pressure trajectories, step length, foot pain, and the moments about the ankle and first metatarsophalangeal joints will be collected and calculated.
