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 aim of the present study is to evaluate the psychophysiological effects of a smart phone based mindfulness meditation app (MMA) for individuals with clinically significant symptoms of major depression and/or anxiety, or symptoms of chronic pain. Specifically, the study aims to examine parasympathetic tone using HRV (primary outcome), mind-wandering and present awareness, mood symptoms, and breath focus in groups of participants who self-report clinically significant symptoms of depression and/or anxiety (DA), chronic pain symptoms (CP), as well as control participants who do not meet our criteria for either (Controls (C). All study groups will be randomized to a mindfulness meditation app (MMA+) condition or a mindfulness meditation condition without the app (MMA-) after a brief stress-induction procedure.
This study investigates the effect of high intensity exercise, with and without the inflammation inhibitor, ibuprofen, on plasma levels of IL-6 and other selective biomarkers of inflammation and appetite on food intake and subjective ratings of appetite in normal-weight boys.
Warfarin remains the only oral anticoagulant effective in preventing stroke and valve thrombi for patients having mechanical heart valves (MHVs). Within Edmonton, Alberta, our pharmacist-directed and staffed Anticoagulation Clinic (AC) is referred all MHVs implanted, and now has ~450 active patients. The AC mandate is to work with patients to ensure they have a thorough understanding of their warfarin therapy and the factors that may impact its control. In European countries patients are often taught to manage their own warfarin therapy (=Patient Self-Management [PSM]) and achieve good warfarin control and outcomes. Despite advocating for a patient-centred approach for healthcare delivery in Alberta, no established programs (or funding models) exist to teach and provide ongoing support for PSM in North America. The patient population (namely MHVs) served at our AC offers a unique opportunity to implement PSM given they are already aware of their therapy and only require some extra training and support to assume their own management. While it is anticipated that an increase in pharmacist AC resources would be necessary to teach patients to self-manage, the establishment of a PSM program has the potential to free up AC resources in the long-term, allowing more patients to be managed with reducing waiting times for the AC. With infrastructure in place, the AC could serve as a centre of excellence for PSM, accepting referrals for this level of care from across the province. Given the patient-centred approach to care delivery in Alberta, it remains prudent to assess patient acceptability to the PSM approach to anticoagulation care delivery. As such, the primary objective of this randomized pilot study is to assess the effect of PSM compared to AC care on quality of life. Our results will inform a larger scale future trial.
The study is single-blind with a randomized, cross-over design to evaluate gastrointestinal tolerance of carbohydrate blends.
This project is focused on helping one of the most vulnerable patient populations in medicine, patients with end-stage chronic lung disease. Lung transplantation is the only cure for end-stage lung disease, however, due to the persistent shortage of donor organs, either due to low organ donation rates or unacceptable organs, only a minority of patients receive desperately needed lung transplants. Currently less than 30% of potential donated thoracic organs are being used for transplantation. The major causes for under utilization of donor thoracic organs are injury sustained by the lungs in trauma or emergency resuscitation or lungs that come from donors who are pronounced dead due to cardiac arrest (known as DCD donors). It has been hypothesized that these injuries may be reversible or repairable if there was an opportunity to evaluate and repair these organs outside of the body (ex-vivo), prior to transplantation. In fact, studies have shown that the use of normothermic Ex-Vivo Lung Perfusion (EVLP) has increased the rate of donor organ utilization at centers that have adopted the technology. Current methodology for all clinically available EVLP devices uses Positive Pressure Ventilation (PPV). Researchers at the University of Alberta (UofA), however, have developed an EVLP device that will apply Negative Pressure Ventilation (NPV) to the lungs, as opposed to PPV, which is the most ideal mimicry of native lung physiology. The objective of this early feasibility safety trial is to show that the UofA developed NPV-EVLP device is acceptable in evaluating and improving the quality of marginal donor lungs compared to currently used EVLP devices, ultimately allowing for these types of donor lungs to be safely transplanted into patients on the lung transplant recipient waitlist.
Community walking is an issue that older adults with chronic conditions have described as important to participation in the community. Walking outside the home is a universally accessible form of physical activity that has multiple health benefits. Walking for 150 minutes per week can help reduce the risk of cardiovascular disease, hypertension, stroke, diabetes, osteoporosis, and depression, as well as falls. Practice walking across roads, slopes and curbs, while talking, and dealing with crowds and traffic, is safe and feasible and can improve confidence, balance and walking ability. Being physically active outdoors in nature appears to improve mental health more than being active indoors. Despite these health benefits, the majority of older Canadians do not walk outside on a regular basis. Barriers to walking outside include fear, physical disability due to chronic disease, the appropriateness of footwear and walking aids, and the physical environment, such as uneven pavement, weather and temperature. To date, the best strategy for getting people to walk outdoors regularly is unknown. The investigators propose to evaluate the effectiveness of a dynamic 1-day workshop, at which older adults who infrequently walk outdoors learn strategies to facilitate outdoor walking, such as appropriate use of footwear, ambulatory aids and equipment, goal setting, and practice skills related to increasing outdoor walking. The workshop will be compared to the workshop plus involvement in a walking group for 3 months. Outcomes include outdoor walking activity, total physical activity, walking ability, participation, and health-related quality of life. Each participant will have four evaluations: baseline, 3, 5.5 and 12 months later. The investigators will interview select participants at 6 and 12 months to ask them about their opinions of what worked and didn't work. Increasing outdoor walking is expected to improve health and well-being, and help people live independently in the community for longer.
The purpose of this study is to assess AR101's safety, tolerability and efficacy over an extended dosing period.
A 24-hour Caffeine Intake Recall (CIR-24) was developed to estimate caffeine consumption in the previous 24 hours, modeled after the Automated Self-Administered 24-hour Dietary Assessment Tool (ASA24), using a brand-specific database of caffeine-containing foods, beverages and supplements. The objective of this study was to evaluate the accuracy of the CIR-24 compared to caffeine concentration biomarkers in urine and a caffeinated beverage intake frequency screener (CBQ) among a young adult population. 79 young adults ages 18 to 29 years provided 24-hour urine samples and completed the CIR-24 and CBQ. Excretion rates for caffeine and eight caffeine metabolites were quantified from urine samples using high performance liquid chromatography-polarity switching electrospray ionization-tandem quadrupole mass spectrometry with stable isotope labeled internal standards.
Perinatal depression occurs in 15% of pregnant women and new mothers, yet as few as 1 in 5 receive adequate treatment. It has a negative impact on the woman herself, as well as a potential for serious consequences for her child. Virtual psychiatric care is a potential model that may provide accessible mental health care during this time, as barriers to in-person care often include unpredictable infant schedules, competing childcare demands, or travel/cost challenges. The Virtual-PND intervention consists of 12-weeks of the option of supplementing in-person psychiatric care with secure, in-home real-time video-visits through the Ontario Telemedicine Network. This pilot RCT will demonstrate the feasibility of proceeding to a future large-scale RCT evaluation of virtual psychiatric care for this population.
