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 is a Phase I trial investigating the safety of using thioridazine in addition to cytarabine in elderly patients with relapsed or refractory Acute Myeloid Leukemia.
Ureteric stents are used often following ureteroscopy for prevention of obstruction from edema and or stone fragments. They are often associated with pain, voiding often, the need to urinate quickly and finding blood in the urine called "lower urinary tract symptoms" or LUTS for short. There is randomized studies showing the efficacy of α-blockers such as tamsulosin in relieving "stent symptoms" (pain and LUTS). There is emerging but limited evidence to show that antimuscarinic medications, used to treat overactive bladder (OAB) have some efficacy in decreasing stent symptoms. Mirabegron is a beta-agonist used to decrease OAB symptoms. Mirabegron functions to mediate relaxation of the detrusor muscle and has been useful in treating OAB symptoms. Conventional antimuscarinic medications often have bothersome side effects like dry mouth, constipation, blurred vision and cognitive impairment. This may limit their use in some populations. Mirabegron is well-tolerated with a good safety profile and therefore may be useful in treating stent symptoms without the bothersome side effects commonly seen with antimuscarinic medications. . The investigators hypothesize that mirabegron is effective in decreasing ureteral stent related LUTS and pain.
Before a patient gets a spinal/epidural, their lower back is cleaned with an antiseptic solution diluted in alcohol called ChloraPrep. ChloraPrep must completely dry before starting the anesthetic procedure. It is not known how much time is needed for the solution to completely dry. The investigators aim to determine this. As the ChloraPrep dries, the alcohol is converted into vapour. The investigators will be using a PPBRae 3000 device to detect small amounts of vapours in the air. As the ChloraPrep dries it gives off less and less vapour. The investigators will use this diminishing vapour concentration to determine when drying is complete.
Stimulants and drugs are often associated with cardiac effects. Caffeine, a therapeutic xanthine, has been described as a sympathomimetic and has shown to have stimulatory effects on the heart. Patients with symptomatic cardiac arrhythmias are generally informed by their physician to stop or significantly reduce caffeine intake. However, in spite of numerous reports that have reviewed the cardiac effects of caffeine, it remains unclear to what extent this stimulant may be detrimental, and what subgroups of patients may be most vulnerable. The investigators propose to evaluate the effects of caffeine in patients with previously diagnosed cardiac arrhythmias. The results of our report will provide important new information for physicians and patients regarding the effects of caffeine on symptomatic cardiac arrhythmias.
This phase I/II trial studies the side effects and best dose of adavosertib and irinotecan hydrochloride in treating younger patients with solid tumors that have come back (relapsed) or that have not responded to standard therapy (refractory). Adavosertib and irinotecan hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
Amino acid are the building blocks of the body's protein. Some amino acids, including leucine, cannot be made in the body and must be obtained from diet, these are called essential. With increase in age the body's muscle mass decrease and studies have suggested that dietary supplementation of leucine may have potential health benefits in elderly in regards to prevention of age related loss of lean muscle mass, and thus may help improve the quality of life in elderly. Currently, a safe upper dietary intake level of leucine has not been established for healthy elderly. Prior to exploring whether leucine supplementation will prevent or decrease loss of lean muscle mass in elderly we propose to identify the upper intake of leucine in healthy elderly. The purpose of this study is to determine the tolerable upper intake level (UL) of leucine in healthy elderly men (70 - 75 yrs) The investigators hypothesize that with a careful graded stepwise increase in leucine intake in elderly men, above the Estimated Average Requirement (EAR - 50 mg/kg/d), the body's ability to oxidize/dispose of excess amino acids will reach a maximum. With increased leucine intakes we hypothesize an increase in plasma ammonia concentrations and increases in plasma leucine and urinary leucine excretion.
Oxygen is carried in the blood attached to hemoglobin molecules. Oxygen saturation is a measure of how much oxygen hemoglobin is carrying as a percentage of the maximum it could carry. Oxygen saturation can be measured non-invasively using pulse oximetry. On occasion, term infants are admitted to the intensive care nursery for monitoring and show variability in their oxygen saturation despite appearing well. As healthy newborns do not undergo routine monitoring of oxygen saturation, health care team do not know the degree to which variability in oxygen saturation are a normal phenomenon. With increasing interest in using pulse oximetry as a screening tool to identify "at risk" newborns, it is important to have a clear understanding of postnatal oxygen saturation trends and their variability in healthy babies. In our study, Investigators will measure oxygen saturation on healthy newborns repeatedly and for extended periods. This will allow us to describe both the variability in oxygen saturations and the pattern of changes observed in oxygen saturations over time in healthy newborns. To increase our confidence that babies included in our study were healthy at birth, they will be followed for 8 weeks to identify indicators of perinatal disease that was missed clinically. Any babies subsequently identified as having significant disease will be analyzed separately from the main cohort of healthy babies. Furthermore, the oxygen saturation readings will be obscured so as not to influence caregivers inappropriately. Lastly, pulse oximetry measurements will be performed after discharge from hospital (on day 3 to 4), potentially increasing the clinical utility of this study as it has repeatedly been stated in the literature that the sensitivity of pulse oximetry to detect important underlying disease increases significantly if performed several days after birth. This study will provide important and novel normative data.
