There is growing evidence for the effectiveness of internet-delivered cognitive behaviour therapy (ICBT) for post-secondary students with symptoms of depression and anxiety. In ICBT, clients review structured online content over several weeks to learn strategies and skills to manage their symptoms. Low treatment completion rates remain a concern for post-secondary students, so it is possible that existing treatment protocols do not offer enough flexibility for students' needs and preferences. This trial will examine students' preferences for different course options (fast-track, 5-week, and 8-week) and compare enrollment, adherence, and outcomes of students who pick each of the three options. In all three options, students will receive optional therapist support, in which the assigned therapist only contacts the student on weeks where the student sends the therapist a message. This trial will help inform the delivery of flexible treatment options for post-secondary students in a routine care setting.

This is a pilot study examining the delivery of a remotely delivered, one-on-one, individualized physical activity (PA) program in adult participants with treatment-resistant depression (TRD).

The Quantum Menstrual Health Monitoring Study will measure four key reproductive hormones in the urine to characterize patterns that predict and confirm ovulation, referenced to serum hormones and the gold-standard of the ultrasound day of ovulation in participants with regular cycles. These normal cycles will provide a reference for comparison to irregular cycles in polycystic ovarian syndrome (PCOS) and athletes. Clinical signs in the menstrual cycle (e.g. menstrual bleeding, temperature) as well as vital sign and sleep patterns will also be referenced to hormonal changes.

More than 5 million people live with Alzheimer's dementia (AD) in North America. No effective treatment exists yet probably because by the time AD has developed it is too late to intervene. Mild Cognitive Impairment (MCI) is a clinical state that typically precedes AD. In MCI, the prefrontal cortex supports compensatory mechanisms that depend on robust synaptic plasticity and that delay progression to AD. Using a neurostimulation approach that enhances prefrontal cortical plasticity in vivo, this project aims to enhance prefrontal cortical plasticity and function in patients with MCI. If successful, this project would discover a treatment modality that enhances compensation in MCI and ultimately, prevents progression to AD.

The hypothesis is that the daily use of brass mesh bolus achieves a comparable dose to every-other-day use of Superflab bolus (current standard of care) in chest wall post-mastectomy patients treated with rotational 6 MV photon delivery.

The "Pharmacogenomics of Stimulant Treatment Response" (PGx-STaR) study aims to identify genetic profiles related to methylphenidate treatment outcomes in children and adolescents aged 6-17 with Attention deficit/hyperactivity disorder (ADHD).

Project rationale: Vasovagal syncope (VVS) affects up to 50% of people, and recurrent syncope markedly reduces quality of life. We recently reported that it is frequently associated with injury and not surprisingly with clinical anxiety. Although conservative measures help many patients there remain many who require more care. CIHR-funded studies have shown that fludrocortisone and midodrine are effective but cannot be used in patients with contraindications such as hypertension and heart failure. Pacemakers are partially effective in older patients, but this is established only in the small minority with proven asystole. There remains a need for a simple, once-daily medication with few contraindications that can be used as first-line therapy for most patients with recurrent vasovagal syncope. Preliminary Studies: Norepinephrine transport (NET) inhibitors show promise as a novel treatment. Three (reboxetine, sibutramine, and atomoxetine) all prevent vasovagal syncope in healthy subjects and vasovagal syncope patients on tilt tests. Atomoxetine, approved to treat attention deficit disorder, is a highly selective NET inhibitor. We reported a proof-of-principle, randomized, placebo-controlled trial of the efficacy of atomoxetine to prevent vasovagal syncope on tilt table tests. Patients underwent tilt testing after receiving either atomoxetine 40 mg or placebo. Fewer VVS patients fainted with atomoxetine than placebo (10/29 vs. 19/27; odds ratio 0.22, p \< 0.01). Our meta-analysis of the effects of NET inhibition on the vasovagal reflex induced by tilt tests was highly positive. A pre-post study showed that sibutramine reduced syncope frequency in highly symptomatic and drug-refractory patients. A similar pre-post study showed that atomoxetine also reduces syncope frequency about 85% in patients with frequent and drug-intolerant or drug-resistant vasovagal syncope. Therefore,NET inhibition by atomoxetine merits assessment based on positive proof-of-principle studies, an apparent class effect, and two open-label pre-post studies. These results provide the rationale for a formal randomized, placebo-controlled, crossover trial of atomoxetine in moderate-to-high risk patients with VVS. Hypothesis: We will test the hypothesis that oral atomoxetine prevents syncope in patients with recurrent VVS. The Study: Patients will be included based on a positive Calgary Syncope Symptom Score and a history of at least 2 faints in the previous year. Eligible patients will be randomized to atomoxetine 40 mg po twice daily or matching placebo in a randomized, placebo-controlled, parallel design, double-blind, crossover trial. Each arm will last 6 months with a 1-week washout period. The primary outcome measure will be the proportion of patients with at least 1 syncope recurrence. The study will be powered to detect a beneficial odds ratio of 0.5, selected on the basis of the control outcome rates in 2 similarly designed, previous studies and international expert requirements for effect size. A sample size of 180 subjects will provide 85% power of detecting a difference between the arms at p\<0.05. We will assess the effects of atomoxetine on quality of life, anxiety, injury, and the cost-effectiveness of atomoxetine treatment, and the effects of genetic factors on outcomes. Substudies : The quality of life scales will be the SF-36 and the Euroqol EQ5D, which will also be used as the health utility index for the economic studies. The depression and anxiety scales will be the Hospital and Anxiety Depression Score (HADS) and the General Anxiety Disorder - 7 Score (GAD-7). Clinical anxiety is highly prevalent in patients with recurrent syncope. Injury will be self-reported using our published definitions. The health economic substudy will be from the health system perspective and will use Alberta administrative data. DNA will be collected from spit acquired in the Oragene saliva self-collection kits, and an initial candidate gene study might include alleles of CYP2D6, COMT, the serotonin (SLC6A4) and norepinephrine (SLC6A2) reuptake transporters, and the 5HT1A and 5HT3 receptors. Summary: Adults who faint recurrently are highly symptomatic. There are no therapies suitable for most patients have withstood the test of randomized clinical trials. If successful, atomoxetine will reduce syncope and improve quality of life.

The Impact 360 study will evaluate the effects of a combined intervention of exercise, mindfulness, and nutrition on 8 key indicators of health and the mechanisms that drive these changes. 60 subjects aged 50 to 75 without a current diagnosis of a brain disorder will be recruited. This study will follow a partial crossover design. All participants will receive the intervention. Participants randomized into the intervention group after their baseline screening will receive the 6-month intervention. Those randomized into the waitlist group will complete another assessment at the end of the 6-month care as usual phase before receiving the intervention.

The goal of the clinical trial is to test whether a mental health program that is delivered through the Internet works well for healthy children and adolescents with siblings with cystic fibrosis (CF). The main questions it aims to answer are: * Does the program improve the mental health and quality of life of healthy siblings? * Does the program improve the relationship between healthy children and adolescents and their sibling with CF? * Does the program help healthy siblings learn about CF? Participants will: * Fill out an online survey asking questions about their family and mental health before the program * Complete the online mental health program over five weeks * Fill out a weekly question asking about their mood for 10 weeks * Fill out an online survey asking questions about their family and mental health after the program Healthy children and adolescents with siblings with CF will be compared against themselves. Researchers will compare participants scores before starting the program with their scores during and after completing the program. Researchers hope to develop a program that improves mental health, quality of life, sibling relationships, and knowledge about CF.

A randomized study of 131 patients. Patients with a clinical T2-3 N0 rectal cancer will be randomized to two arms (arm A: standard chemoradiation (45 Gy in 25 with concomitant 5-FU or Xeloda chemotherapy) and an external beam boost of 9 Gy compared to arm B: standard chemoradiation (45 Gy in 25 with concomitant 5-FU or Xeloda chemotherapy) and followed by a brachytherapy boost of 30 Gy in 3 fractions).
