This study wants to develop health messages to encourage flu vaccination. You will take part in a 60-minute focus group discussion or individual interview to develop the messages. As a thank you for your time, you will receive a $25 gift card and we'll cover parking/transit costs if travel is required.

Through five brief electronic questionnaires, this study will explore how social factors, like financial strain, discrimination and cannabis use affect the health of mothers and their babies in Canada, during pregnancy. There is an urgent need to learn more about the experiences of pregnant Canadians so that we can provide up-to-date, accurate educational information and ensure that everyone receives the best care possible during pregnancy. All pregnant individuals between the ages of 16-45 years old in Canada who are at least 30 weeks along are eligible and encouraged to participate. You are also eligible if you have delivered your baby early, but have not yet reached your original due date. Those who enrol will be sent online surveys to complete immediately, as well as 6, 12, 24, and 36 months after they deliver their baby (or babies). Survey responses will be linked to electronic health records. We will also invite select individuals, who live in the Calgary area, to take part in a sub-study that will use magnetic resonance imaging (MRI) and other assessments to measure your child's brain health along with thinking abilities, feelings, behaviors and emotions. These tests will take place when the infant is 3 and 36 months of age.

This study is comparing two different anti-arrhythmic agents in patients that develop atrial fibrillation soon after cardiac surgery.

The purpose of this study is to determine if POTS and Long COVID patients perform as well as healthy people on tests of cognition (thinking). The results of this study may help us to better understand if POTS and Long COVID patients' complaints of "brain fog" needs to be studied more carefully. Postural Tachycardia Syndrome (POTS) is a disorder that features an inappropriate increase in heart rate upon standing in addition to chronic symptoms including lightheadedness, dizziness, mental clouding, and palpitations. A common complaint among people with LC & POTS is “brain fog” – a difficulty in concentrating. We are trying to learn more about this “brain fog”. To do this we are are conducting some tests of brain function (on paper and on computer). We are also measuring heart rates and blood pressures while lying down and standing up.

About 20% of adults faint regularly. No treatments are proven useful in executed clinical trials. This is a study to test the theory that Ondansetron reduces the time to a recurrence of faint in a TILT test. In this study half the patients will receive Ondansetron the night before and the morning of the study day ( TILT Table test) the other half will receive a Placebo. you need to fill in two surveys. No follow-up needed after the study day.

To test a novel wearable blood pressure monitoring device. You will be asked to perform a few everyday physical activities like sitting, squatting etc while having your blood pressure monitored.

We want to see if a short, bedside ultrasound assessment is as good as invasive testing to help determine if the blood volume and pressures are normal or not. To do this, we will compare our clinical assessment of blood volume alone, or with a short ultrasound of the lungs and heart to the gold standard of measured pressures obtained via an invasive cardiac catheterization.

We are studying if increased carbon dioxide (CO2) can increase blood pressure and reduce symptoms in patients with Neurogenic Orthostatic Hypotension (NOH) and healthy volunteers. Participants will perform four active stand tests under different CO2 levels. We will monitor blood pressure, heart rate, and brain blood flow to determine which intervention is the most effective in minimizing symptoms and improving blood pressure. We will also take pictures of the blood vessels in the eye to better understand changes happening close to the brain

The PONI lab is investigating how a new markerless motion capture system measures how pediatric populations walk. Motion capture is an important tool for informing the clinical care of children with Cerebral Palsy and other mobility impairments. The standard motion capture system in most labs is a marker-based system. This system requires small reflective markers to be attached to the participant's joints (similar to how animated movies and video games are made). This can be time-consuming, so we are interested in understanding how a new system that does not require the use of markers works. Participants will be asked to walk back and forth with both the marker-based and markerless systems recording them walk. Participants will be asked to wear shorts and a t-shirt.

The goal of this study is to learn more about the genetics of neurological conditions. We are collecting DNA and RNA samples from blood for use in experimental gene sequencing methods. We are recruiting individuals with neurologic conditions, as well as control participants.
