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.
Postdural puncture headache (PDPH) is a severe, debilitating complication of dural puncture that can arise from insertion of an epidural or spinal needle for labour analgesia. Presently, the conservative treatment options for PDPH have limited effectiveness and the gold standard treatment for PDPH, an epidural blood patch, is an invasive intervention with the potential for serious complications. There is a growing number of case reports and retrospective studies that suggest a sphenopalatine ganglion block (SPGB) with local anesthetic may offer an effective, safe, and easy-to-administer treatment option for PDPH in postpartum patients. We aim to conduct a feasibility study to assess whether a randomized controlled trial is feasible comparing whether early intervention SPGB with the option for repeat, patient self-administered SPGBs versus current standard conservative management can reduce the severity and duration of PDPH pain and improve patient functional status.
A Phase 2b, study to measure the effect of Cotadutide at different doses versus placebo or comparator (semaglutide) in participants who have Chronic Kidney Disease with Type 2 Diabetes Mellitus.
The overarching aim of this project is to implement and evaluate a proven cognitive training regimen in combination with a community exercise program among older adults who attend wellness exercise programs at the YMCA. To support this aim, the investigators have developed a collaboration with the YMCA of Kitchener-Waterloo, which offer exercise programs targeted to older adults. The specific objectives are: (1) to evaluate the feasibility of a combined exercise and cognitive training in a community-setting among older adults; and (2) to conduct a preliminary evaluation and comparison of changes in cognitive function, physical function, well-being and self-efficacy with 12-weeks of combined exercise and cognitive training versus exercise alone. The hypothesis for each objective are as follows: (1) It is anticipated that this program will be feasible to implement and will be well accepted by the participants and exercise providers. (2) The investigators may not have the power to find statistically significant differences between the control and experimental groups for physical and cognitive function. However, the investigators expect to observe positive changes between the pre- and post-assessments, suggesting improved cognitive function and mobility as a result of the 12-week program.
This study will evaluate the performance of two point-of-care dual syphilis and HIV tests [Multiplo TP/HIV test (MedMira Inc, Halifax, Nova Scotia) and the INSTI Multiplex HIV-1/HIV-2/Syphilis Antibody Test (bioLytical Laboratories Inc., Richmond, BC)]. In addition to standard syphilis and HIV testing, point-of care testing (POCT) will be performed on 1,500 consecutive participants who are being screened for syphilis and HIV and who are at least 16 years old. POCT will be conducted using a fingerprick whole blood specimen. The study will be conducted at multiple sites in Northern Alberta (Canada), a region which is currently experiencing a resurgence of infectious syphilis.
Skeletal muscle plays several different roles in the promotion and maintenance of health and well-being. The loss of muscle mass that occurs with aging, chronic muscle wasting diseases, and physical inactivity puts people at an increased risk of frailty and becoming insulin resistant, and therefore imposes a significant burden on health care spending. Resistance exercise participation has proven particularly effective for increasing muscle mass and strength. This effectiveness can be used by health care practitioners in a rehabilitation setting to promote the recovery of individuals who have undergone involuntary periods of muscular unloading (i.e. limb immobilization caused by a sports injury or reconstructive surgery). However, there is large variability in the amount of muscle mass and strength that people gain following participation in resistance exercise. Some individuals fail to increase the size of their muscle (low responders) whereas others show vary large increases in muscle size (high responders) in response to the same resistance training program. People also show differences in the amount of muscle tissue they lose when they have a limb immobilized. To circumvent variability across individuals, the investigators utilized a within-person paired Hypertrophy and Atrophy ('HYPAT') strategy that reduced response heterogeneity by ~40% (Available at: https://ssrn.com/abstract=3445673). Specifically, one leg performed resistance training for 10 weeks to induce hypertrophy, whereas the other leg underwent single-leg immobilization for 2 weeks to induce atrophy. The primary goal of the study will be to gain insight into the molecular responses to an acute period of single-leg immobilization and resistance exercise (8 days). The investigators will use an integrated systems biology approach to monitor the individual rates of over one hundred different muscle proteins.
The conventional approach to heart valve operations is through a sternotomy. This involves a vertical incision in the sternum (breastbone) to gain access to the heart and its related structures. Post-operative recovery after sternotomy can take anywhere from 6 weeks to 3 months due to the time required for the sternum to fully heal. Minimally invasive valve surgery is a less invasive alternative to conventional open-heart surgery. At the Foothills Medical Centre, surgeons perform minimally invasive valve surgery through a technique called right mini-thoracotomy. This involves a small incision on the right upper chest and leaves the sternum fully intact. It is unclear whether minimally invasive valve surgery provides better clinical outcomes and quality of life compared to conventional open heart surgery. The purpose of this research study is to compare the clinical outcomes of minimally invasive valve surgery via right mini-thoracotomy to conventional surgery via open-heart surgery. The results of this study will inform surgeons of the benefits and disadvantages of minimally invasive surgery compared to the current standards. This will help in developing better treatment strategies for patients requiring valve therapy.
The purpose of this study is to evaluate the efficacy and safety of atezolizumab in combination with tiragolumab compared with durvalumab in participants with locally advanced, unresectable Stage III non-small cell lung cancer (NSCLC) who have received at least two cycles of concurrent platinum-based chemoradiotherapy (CRT) and have not had radiographic disease progression.
The purpose of this study is to assess the efficacy of seltorexant compared with quetiapine extended-release (XR) as adjunctive therapy to an antidepressant drug in treatment response in participants with major depressive disorder with insomnia symptoms (MDDIS) who have had an inadequate response to current antidepressant therapy with a selective serotonin reuptake inhibitor (SSRI) or serotonin-norepinephrine reuptake inhibitor (SNRI).
To determine if there is a need for further education on vaccines with psoriasis patients who are on a biologic. In regards to the COVID-19, it is important that psoriasis patients - whether on a biologic or not - understand whether they can have certain vaccines. That will depend on the type of vaccine that becomes available.
This phase III trial compares less intense hormone therapy and radiation therapy to usual hormone therapy and radiation therapy in treating patients with high risk prostate cancer and low gene risk score. This trial also compares more intense hormone therapy and radiation therapy to usual hormone therapy and radiation therapy in patients with high risk prostate cancer and high gene risk score. Apalutamide may help fight prostate cancer by blocking the use of androgen by the tumor cells. Radiation therapy uses high energy rays to kill tumor cells and shrink tumors. Giving a shorter hormone therapy treatment may work the same at controlling prostate cancer compared to the usual 24 month hormone therapy treatment in patients with low gene risk score. Adding apalutamide to the usual treatment may increase the length of time without prostate cancer spreading as compared to the usual treatment in patients with high gene risk score.
