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.
One of the many uses of cardiac magnetic resonance (CMR) is the assessment of right ventricular (RV) volumes. There are a number of congenital heart defects and acquired conditions in which management decisions are fundamentally based on ventricular volumes. The "gold standard" for assessment of RV volume is CMR. It has better near-field resolution than echo and excellent contrast between the blood pool and the myocardium. CMR is more suitable to the irregular geometry of the RV. The objectives of this study are (1) to assess ventricular volumes in the fasting state and after oral hydration in order to assess the effect of fluid status on ventricular volumes as measured by CMR; (2) to evaluate the effect of hydration on ventricular volumes compared the effect of with inter-observer and intra-observer variability, and; (3) to evaluate the effects of chamber volume on chamber deformation, including strain and peak strain rate. This study hypothesizes that (1) hydration status has an effect on right and left heart volumes, measured by CMR in healthy volunteers; (2) the effect of volume status will be a more significant contributor to variability in RV volumetry than that of inter-observer variability and intra-observer variability, and; (3) atrial and Ventricular deformation corrected for chamber size or volume is more accurate than when uncorrected for volume.
The primary objective of the study is to confirm that at least 1 or more doses of telotristat etiprate compared to placebo is effective in reducing the number of daily bowel movements (BMs) from baseline averaged over the 12-week double-blind portion (Treatment Period) of the trial in patients not adequately controlled by current SSA therapy.
This open-label, extension study is designed to provide continuing treatment with RO5045337 to participants who have completed parent studies NO21279 (NCT00623870), NO21280 (NCT00559533), NP25299 (NCT01164033), NP28021 (NCT01605526) or NP28023 (NCT01635296). Participants are eligible to participate in this study if they have completed required Phase 1 study assessments for primary objectives of respective parent protocol and are having evidence of clinical benefit (as defined by the parent protocol). Participants will continue the most similar dose and formulation available (which does not exceed the maximum tolerated dose [MTD] or the maximum safely administered dose for that formulation during Phase 1) and the same schedule of RO5045337 treatment that they were receiving at the time of transitioning from the parent clinical study protocol.
This Phase II, multicenter, randomized, double-blind, parallel-group, placebo-controlled study will evaluate the efficacy and safety of RO4602522 in participants with moderate severity Alzheimer's disease. Participants who are taking background therapy of acetylcholinesterase inhibitors (AChEI) alone or in combination with memantine for at least 4 months before screening will be randomized to receive either one of two doses of RO4602522 or placebo for 12 months.
This was a 2-part, Phase I/IIa, multi-center, open label, study in pediatric and adolescent patients with advanced BRAF V600 mutation-positive solid tumors. Part 1 was a dose escalation study in patients with any BRAF V600 mutation-positive solid tumor using a modified Rolling 6 Design (RSD). Part 2 was an expansion study to further evaluate the safety, tolerability, and clinical activity of dabrafenib in 4 tumor-specific pediatric populations. Patients participated in only either part 1 or part 2 of the study.
Blood pressure is typically measured with a non-invasive cuff placed on the upper arm. This cuff cannot take accurate measurements when the patient's arm is moving. Anesthesia for a cesarean delivery frequently causes the patient to shiver and their arm to shake, and sometimes to the extent that blood pressure cannot be measured. A cuff placed on the wrist may be more effective when a patient is shivering because their lower arm moves less and can be more easily stabilized. We will be taking simultaneous blood pressure measurements both just before and during cesarean deliveries in order to compare blood pressure at the upper arm versus the wrist.
The primary purpose of this registry is to obtain "real world" clinical use of contact force measurements during ablation procedures.
Establish an international registry of over 400 patients with deep infections involving the bone and/or joint from≥20 centers representing all regions of the world with varied hospital and surgeon practice settings to ensure that registry analyses and research reflect typical clinical practice thereby providing optimal guidance for patients, clinicians, and healthcare researchers. Using a data collection platform that minimizes entry burden, collects most information at the time of surgery, and uses Internet technology to minimize data entry. The registry will include: 1. baseline patient attributes; 2. surgical approach, implants and technology; 3. hospital course; 4. surgeon and institutional characteristics; 5. longitudinal patient outcome, 6. post-procedure complications and revisions, 7. serum/tissue/drainage samples.
The SickKids-led research team is currently developing a prenatal micronutrient powder that will contain calcium, iron, and folic acid with different absorption characteristics. Once the powder is developed, it can be incorporated into various oral delivery vehicles. The overall effectiveness of a micronutrient program is highly dependent on the acceptance and regular consumption of supplements (i.e., adherence) by the targeted users. This is a study of the preference, acceptability, and palatability of 4 alternative delivery vehicles for the innovative prenatal multiple micronutrient supplement: traditional tablets, oral disintegrating tablets, unflavoured powder with a suspension agent, and flavoured powder with a suspension agent. This study will be conducted in Dhaka, Bangladesh. This study hypothesizes that that the formulation of the delivery vehicle will impact preference, acceptability, and palatability.
Hypoxemia is an abnormally low concentration of oxygen in the blood, and is an important sign of cardio-respiratory compromise in acutely ill patients. Pulse oximetry (PO) is a rapid, portable, non-invasive and accurate method of measuring arterial hemoglobin oxygenation (Sp02), and can therefore be readily implemented to detect hypoxemia in the clinical setting. In this research study, we propose to test the hypothesis that the use of pulse oximetry to detect hypoxemia by first-level health workers' in Karachi, Pakistan is useful and feasible for the identification of the infants most urgently in need of medical care. We will enroll 1,400 infants 0-59 days of age who present to one of two primary health centers in Karachi. Infants will undergo brief clinical assessment by a community health worker (CHW) based on the WHO/UNICEF Integrated Management of Neonatal and Child Illness (IMNCI) algorithm, assessment by two pulse oximetry devices, and examination by a physician. The primary outcomes include prevalence of hypoxemia, feasibility of PO (e.g., time to obtain measurement, number of infants for who repeat measurements are required), and concordance between paired measurements on separate devices.
