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.
Peripheral pulmonary lesions (PPL) are defined as nodules or masses that are located in the lung periphery; hence cannot be seen via regular bronchoscopy. Due to their location, establishing a pathological diagnosis can be challenging. Investigations of PPL has significantly evolved in the last decade with the development of new technologies such as peripheral endobronchial ultrasound (pEBUS), virtual bronchoscopy and electromagnetic navigational bronchoscopy (ENB). Although these technologies have allowed physicians to safely biopsy previously difficult to access nodules, their sensitivity have been lower than trans-thoracic needle aspiration (TTNA). In fact, the largest registry to date has found a diagnostic yield of pEBUS of 57% compared to 93% for TTNA. However, TTNA caries substantially more procedural risk than pEBUS with a 25% rate of complication vs 2.8% for pEBUS (1, 2). With increased sensitivity, pEBUS could become the procedure of choice for PPL investigation in view of its safety profile. Rapid on-site evaluation of biopsy samples by a cytopathologist (ROSE) allows for direct evaluation of specimen adequacy. By offering real-time feedback to the bronchoscopist about specimen adequacy, the adding of ROSE to pEBUS could lead to an increase in diagnostic yield, allowing for a faster diagnosis of lung cancer and avoiding the need for further diagnostic procedures. Minitiazuration of broncoscopes can also allow navigation to more distal areas of the lung closer to the PPL. While this may also improve diagnostic yield, other technical modification such as the need for smaller sampling instruments and inability to use a guide sheath may have drawbacks. This study will use a 2 x 2 factorial design to compare diagnostic yield of pEBUS bronchoscopic PPL sampling with vs. without ROSE as well as with a novel "slim" bronchoscope vs. standard bronchoscope. The investigators aim to randomize 208 patients to independently test each hypothesis.
To evaluate the safety and efficacy of first-line combination therapy using riociguat with ambrisentan in patients with Pulmonary Arterial Hypertension (PAH).
Patients with post-prostatectomy PSA (Prostate Specific Antigen) recurrences with aggressive disease features will receive salvage radiation therapy and standard androgen deprivation therapy (ADT) or enhanced ADT to determine if there is any improvement in progression-free survival when enhanced ADT is used compared to standard ADT.
The purpose of this study is to examine whether a low dose of CBD+THC will decrease the frequency of convulsive seizures in adults with drug-resistant epilepsy, when used in addition to standard anti-epileptic drugs (AEDs). This study will also study the genes associated with epilepsy and whether different epileptic syndromes respond to treatment with CBD+THC.
The purpose of this study is determine if receiving stereotactic body radiation(SBRT) when participants' metastatic tumors have just begun to grow increase the length of time before disease gets worse
This study will examine the influence of n3 PUFA supplementation on the rate of muscle atrophy in older women undergoing 1 week of unilateral limb immobilization. Assessments in skeletal muscle strength and skeletal muscle volume will also me made before, after and in recovery from immobilization.
Ulcerative colitis (UC) is a chronic inflammatory bowel disease which often follows a relapsing/remitting course. Anti-TNF therapies are proven to be effective in UC and studies indicate that having adequate drug levels correlate with improved patient outcomes. It is unknown, however, if a high burden of disease at baseline impacts drug utilization or loss. In this study, we investigate whether measures of high burden of disease (fecal calprotectin, bowel ultrasound, and colonoscopy) at baseline predicts low drug levels after standard anti-TNF induction therapy.
Testing the efficacy of high intensity interval training (HIIT), as compared to current research supporting moderate intensity continuous training (MICT), as a means to improve cardiometabolic health after spinal cord injury.
The aim of this study is to evaluate the use of a denture adhesive and its ability to demonstrate the improvement in overall gum-health and to improve the oral health related quality of life (OHrQoL) in participants who wear full dentures.
There is a high rate of inappropriate antibiotic use in long-term care (LTC) facilities, with both unnecessary initiation and prolongation of treatments. Although there are challenges to rational antibiotic use in LTC, the variability in antibiotic initiation and use of prolonged treatment durations is driven by prescriber tendencies rather than resident characteristics. Audit-and-feedback is a well-established intervention to improve professional practices, and is ideally suited for use to improve antibiotic prescribing tendencies in LTC. The literature is saturated with trials indicating benefit of audit-and-feedback, but is in dire need of studies to identify methods to improve the impact of this technique. Health Quality Ontario (HQO), a key partner in the FIRST AID-LTC research program, is already providing audit-and-feedback for other inappropriate prescribing practices in LTC, and has identified antibiotic prescribing as a priority focus.
