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 main purpose of this study is to determine the rate and extent of absorption of one or more modified release formulations of amphetamine (HLD100) in both adolescents and children with ADHD.
Inflammation increases with aging and is implicated in the reduction of bone mass, muscle mass, and strength. Resistance training is safe and effective for increasing muscle mass and strength in older adults,however resistance training by itself cannot suppress inflammation. Ibuprofen is a non-steroidal anti-inflammatory drug that may provide benefits to muscle mass and strength when given after resistance training sessions in older adults; however, more evidence is required to confirm effects across the lifespan. The objectives are to determine the effect of 9 months of exercise training and ibuprofen supplementation, compared to placebo, in older women (≥65years)on the following dependent variables: - bone density, geometry, and architecture - muscle mass and strength - balance
One of the main factors in the success of in-vitro fertilization is the quality of the environment of the embryo. In contrast to maternal age, the environment in which the embryo develops is a modifiable factor. Many techniques, such as assisted hatching and perfecting culture media have been attempted in order to reproduce as much as possible the natural, physiological environment of the mother for the embryo in in-vitro fertilization. However, the different new culture media used are devoid of growth factors normally secreted by uterine cells that enhance the interaction between the embryo and its environment. Because the endometrial lining of the uterus secretes many different cytokines necessary for growth of the embryo, a new procedure has been developed to mimic the natural environment of the growing embryo using autologous (patient's own) endometrial cells in co-culture with the embryo. Endocell, a product developed by Genévrier Laboratories, received commercial authorization in France in 2011. It is the only system of autologous embryo-endometrium co-culture available on the actual market. The process consists of developing the embryo on a monolayer of the patient's own endometrial cells in order to favor its growth until the blastocyst stage (day 5) and to improve its implantation.
The standard of care for women with high risk endometrial cancer is the removal of all visible lymph nodes in the pelvis and lower abdomen to identify if disease has spread to these areas. It is estimated that no more than 25% of all women with presumed early stage high risk endometrial cancer will have positive lymph nodes however currently the majority of women are subjected to extensive resection of all pelvic lymph and or para-aortic lymph nodes and its associated morbidities. The objective of this study is to determine if intraoperative sentinel lymph node (SLN) mapping will improve the assessment of regional lymph nodes and enhance the detection of lymph nodes with metastatic disease in endometrial cancer. This would benefit the majority of women with early stage high risk endometrial cancer and would prevent the associated complications of pelvic lymph node dissection.
A preliminary demonstration of the Safety of IPBS in positioning a vacuum assisted biopsy (VAB) tool to enable an MRI-guided automated breast biopsy. This will consist of 10-15 biopsy procedures facilitated by the MRI-guided system. Patients will be followed after the procedure to assess clinical outcomes.
Background: Patients in the intensive care unit (ICU) are the sickest in hospital, and need advanced life-support. Survivors of critical illness are very vulnerable to weakness and disability. Up to 1 in 4 have severe leg weakness impairing their quality of life for as long as 5 years after ICU discharge. In-bed cycling employs special equipment that attaches to a patient's hospital bed, allowing them gentle leg exercise while in the ICU. The investigators will offer patients in-bed cycling while they are needing a breathing machine, to help them recover from weakness as fast as possible. Before doing a larger trial testing if in-bed cycling reduces disability, data on safety (Is it safe?) and feasibility (Can the investigators do it?) are needed. Objectives: To study the safety and feasibility of in-bed leg cycling in critically ill patients who need breathing machines. Methods: Adult patients admitted to the ICU who need a breathing machine and are expected to survive their ICU stay are eligible. Specially trained physiotherapists will provide patients with 30 minutes of in-bed cycling each day while they are in the ICU. Outcomes: The investigators will study (1) Safety: the heart rate and breathing patterns of patients doing in-bed cycling, while carefully monitoring for safety. (2) Feasibility: whether patients can cycle on most days of their ICU stay, whether patients and their families agree to be a part of the study, and whether the investigators can assess patients' strength in the ICU and at hospital discharge. Relevance: As the Canadian population ages, the demand for breathing machines during acute illness will increase dramatically. Effective methods of physiotherapy are needed for critically ill patients to minimize muscle weakness, speed recovery, and improve quality of life. This pilot study is the first of several future larger studies about in-bed cycling in the ICU. This program of research will help patients needing life support to regain their strength and recover as fast as possible from critical illness.
Muscle mass is normally maintained through the regulated balance between the processes of protein synthesis (i.e. making new muscle proteins) and protein breakdown (breaking down old muscle proteins). Proteins are composed of amino acids and we know that amino acids increase muscle protein synthesis. However, not all amino acids are the same. Essential amino acids are ones that must be consumed through food, while non-essential amino acids can be made by our body. Interestingly, the essential amino acids are all that are required to increase the rate of muscle protein synthesis. In addition, the essential amino acid leucine appears to be particularly important in regulating protein synthesis. However, how leucine is able to increase protein synthesis is not entirely understood. Previously, it has been shown that 20-25 g of high-quality protein, such as that found in milk (whey), appears to be the amount of protein that maximizes the rate of muscle protein synthesis after performing a bout of resistance exercise. Thus, we aim to measure the synthesis of new muscle proteins after ingesting different amounts of protein and amino acids. We will measure muscle protein synthesis after consumption of the beverage a participant is randomized to in a leg that has done no exercise ( ie. a rested leg) and in the other leg that has done resistance exercise. Amino acids are 'strung-together' to make protein. The 'essential' amino acids must be consumed through food because our body cannot make them, thus they are consumed when you eat protein rich foods like milk or chicken. Leucine, isoleucine, and valine are simply 3 of the 8 essential amino acids that make up dietary protein. Unlike essential amino acids, 'non-essential' amino acids may be synthesized by the body, however they are also present in protein rich foods like chicken or milk. We aim to determine if it is the leucine content found in 25 g of whey protein that is primarily responsible for maximizing muscle protein synthesis at rest and following resistance exercise. We also wish to determine how muscle genes and metabolism respond to this protocol.
The purpose of this study is to investigate the long-term safety and any side effects of baricitinib in participants who have completed a previous baricitinib rheumatoid arthritis study. The study provides 7 years of additional treatment with baricitinib.
The purpose of this study is to better understand the genetic and metabolic differences in obese individuals with and without type 2 diabetes. It is expected that this research will help improve our understanding of the variability observed between obese and diabetic individuals.
It is hypothesised that ambrisentan may provide benefit to subjects with inoperable chronic thromboembolic pulmonary hypertension (CTEPH), where currently no proven or licensed treatment options exist. This Phase III, randomized, double-blind placebo controlled parallel group, 16 week study will compare the safety and efficacy of ambrisentan 5 milligrams (mg) versus placebo in subjects with inoperable CTEPH. The study will enrol 160 subjects, to assure at least 72 evaluable subjects per treatment arm, based on 10% drop-out rate.
