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 study is designed to evaluate the relationship between diaphragm activity during mechanical ventilation and the development of ventilator-induced diaphragm dysfunction (VIDD). Diaphragm structure, activity, and function are monitored longitudinally over the first 7 days of mechanical ventilation.
Corneal endothelial cells health and pumping function is crucial to permit corneal optical clarity by keeping cornea in relatively dehydrated state. Corneal endothelial damage has been associated with most types of intraocular surgery. Trabeculectomy is the standard glaucoma surgical intervention in management of progressive glaucoma despite of medical therapy which can be performed in combination with Cataract surgery (Phacoemulsification and IOL implantation) in patients with cataract-impaired visual acuity. In this study, the investigators will investigate and compare the corneal endothelial cells number and health status before and after trabeculectomy vs. combined surgery (at 1 month and 3 months post-op visits) using Specular microscopy which is a non-invasive technique to access the structure and function of the corneal endothelium by permitting visualization of the corneal endothelial mosaic to assess the effect of this surgical intervention on corneal endothelial cells health and number.
The OReO study will be a Phase IIIb, randomised, double-blind, placebo-controlled, multicentre study to assess the efficacy and tolerability of Olaparib retreatment, versus matching placebo, in non-mucinous epithelial ovarian cancer (EOC) patients (including patients with primary peritoneal and/or fallopian tube cancer)
Biased attention toward negatively valenced information has been considered as a mechanism for risk and relapse in depression. Those with depression tend to focus their visual attention first, more frequently, and for longer periods of time, if it connotes negative (particularly sad) mood. To this end, investigators have recently discovered that this bias might be modifiable. However, the existing literature is mixed with regard to effectiveness. The investigators propose in this study a novel approach to modifying attention bias in depression by using real time feedback with eye tracking technology. The investigators will examine if, compared to a sham condition, rewarding attention toward positive stimuli results in improved mood and reductions in attention bias. Following three sessions of either sham training or active attentional bias training, the investigators hypothesize that participants in the active training condition will experience a) reductions in negative attentional bias, and b) to an improved mood state and increased quality of life, compared to those in the sham training condition.
The primary outcome of the study is the effect of Hairfinity vs. Placebo on the rate of distal hair growth, assessed using Trichoscan HD, in healthy female adults from baseline to day 90 (end of study).
Alcohol and cannabis are the two most widely used substances of abuse in the world and are the psychoactive substances most often found in seriously and fatally injured drivers. In a recent study, it was observed that individuals who reported both driving under the influence of alcohol (DUIA) and the influence of cannabis (DUIC) experienced collision risk that was nearly 4 times that of individuals who reported driving after using only one of these drugs. Recent research in the United States and Canada indicates that the prevalence of DUIC among young drivers of high school and university age, and young adults is similar to, or higher than, the prevalence of DUIA. This is a serious public health issue, since motor vehicle collisions are the leading cause of death in this age group. Given the frequency with which alcohol and cannabis are consumed together, it is important to understand their combined effects on driver behaviour. The current study will examine the acute effects of a moderate dose of cannabis (12.5% THC) combined with an intoxicating amount of alcohol (BAC=0.08) on driving simulator performance of young drivers. Following an eligibility screening and practice session, a total of 70 participants aged 19 to 29 years will each complete 4 experimental sessions. During each session, participants will drink alcohol or placebo alcohol and smoke an active or placebo cannabis cigarette. The effects of alcohol and cannabis on the performance of driving-related skills will be assessed using a high-fidelity driving simulator. Cognitive, psychomotor, and mood effects will also be assessed.
Some people living with health problems require extra support to properly manage their conditions, as family doctors are only able to spend limited time in the office with these patients. There are many resources and programs in the community that can provide the necessary time and support for these patients, yet many patients are unaware that such resources exist. Patient navigators have been shown to be useful in helping patients with certain conditions (such as cancer) to get to the resources they need, especially when they have social challenges that make it difficult for them to reach these programs (for example, language or transportation barriers, poverty, or poor social support). This study will look at how helpful Navigators are to link patients at family doctors' offices to community resources. To do this, family doctors' offices in Ottawa will be recruited. All offices will receive training on referring patients to community resources, and half of these (intervention) will have a Navigator assigned to the practice. This study will assess whether access to a Navigator increases patients' access to community social and health services. In addition, the study aims to understand whether English and French speaking individuals are as likely to benefit from a Navigator in accessing community health and social services in the language of their choice.
OBJECTIVE AND HYPOTHESIS: The objective of this study will be to examine the effects of watching a screen or listening to music while exercising on acute energy intake and expenditure. It is hypothesized that the post-exercise energy compensation will be greater in both conditions with stimuli (i.e., screen and music) compared with the control condition (i.e., exercise alone). STUDY DESIGN: Randomized, 3-condition crossover study (within-subjects experimental design). PARTICIPANTS: The present study will recruit 25 male adolescents between the ages of 13 and 17 years. Participants will be recruited via advertisements and word of mouth (first come first served approach). OVERVIEW OF THE STUDY PROTOCOL: Preliminary Visit The participants will attend one baseline session and three experimental sessions. The preliminary visit will include measurements related to anthropometry (body weight, height, waist circumference) and resting metabolic rate. Participants will also complete questionnaires in order to better characterize them. Experimental Sessions Each participant will be engaged in each of the following three 30-min experimental conditions followed by an ad libitum lunch: (1) walking/jogging on a treadmill at 60% of VO2 peak while watching a screen (exercise + screen); (2) walking/jogging on a treadmill at 60% of VO2 peak while listening to music (exercise + music); and (3) walking/jogging on a treadmill at 60% of VO2 peak with no other stimulus (control condition). MEASUREMENTS: The main measures for this study include: anthropometric measurements, food intake, appetite sensations, energy expenditure, resting metabolic rate, and ratings of perceived exertion. OUTCOME MEASURES: The primary outcome measure will be post-exercise energy compensation. The food intake outcome will be assessed by using an ad libitum test meal immediately after the conditions and a dietary record for the remainder of the day. The energy expenditure outcome will be assessed by using an Actical accelerometer until bedtime. The secondary outcome measures will include appetite sensations and the ratings of perceived exertion (OMNI scale).
The purpose of this study is to evaluate the efficacy and safety of risankizumab versus placebo during induction therapy in participants with moderately to severely active Crohn's disease (CD).
This short-term study aims to prove the potential cardio-protective physiological effect of inhaled aclidinium bromide/formoterol fumarate on inspiratory pleural pressures. Smoking is associated with gas-trapping (hyperinflation), even in the absence of chronic obstructive pulmonary disease. Breathing in the presence of gas-trapping requires large negative inspiratory pleural pressures, which are transmitted to the surface of the heart and increase cardiac wall stress. Inhaled aclidinium bromide and formoterol fumarate has been shown to reduce gas-trapping, but the impact on inspiratory pleural pressures and biomarkers of cardiac stress in smokers is unknown.
