How can we improve the chances of survival and healthy development for the most vulnerable babies? 🍼

For Dr. Marc-Olivier Deguise, who recently completed his residency in neonatology, the answer lies as much in research as it does in bedside care.

From research on cell therapies to neonatal intensive care, his journey—from the MD-PhD program at the University of Ottawa to his residency at The Ottawa Hospital—illustrates the essential role of clinician-researchers in the future of medicine and their ability to change the course of a life from its very first days. 🎓🩺

“These babies have often had a very rough start in life. Our role is to optimize their care to give them the best possible chance. ”

This is the first profile in our special series, “Class of 2026,” which highlights the journeys of our students as they develop their skills and contribute to advancing medicine, research, and patient care. Stay tuned for the next profiles! 🔊

One day, the medicine coverage and calls may adhere to the evidence that you are simply not at your best after being up for 24 hours

[Dan Go @CoachDanGo]

This is your brain on sleep deprivation.

Scientists in Canada launched the largest study on how lack of sleep affects the brain.

They created games that tested skills like reasoning, language comprehension & decision making.

They had one participant repeat these tests in an MRI machine.

Here's what they found:

On the left is a normal night of sleep.

On the right is when it's deprived of 4 hours of sleep.

The colored areas are the activity happening in your brain. Notice the lack of activity on the right side.

Researchers found there was less activity in the frontal & parietal lobes, which are crucial for decision making, problem solving & mood control.

You are simply not at your best when you don't get enough sleep.

Another study done at the University of Oslo found that lack of sleep leads to reduced clearance of substances from the brain.

These substances are many of the same waste products that are seen to accumulate in the brains of Alzheimer's patients.

Some recent studies suggest that poor sleep contributes to higher levels of beta-amyloid protein in the brain, which lead to the amyloid plaques found in the Alzheimer's brain.

If you want a healthy brain avoid long term sleep deprivation.

What should you do?

• When deprived of sleep avoid making big decisions & pause before reacting to an emotion.

• Fix your sleeping habits. If you can't get enough hours, focus on increasing your sleep quality to make up for it.

Sleep is the best legal performance enhancing drug on the planet.

Make it a priority now so you can protect your brain for later.

It has been a challenging year to say the least. @modeguise and I thought that it was time for a little celebration 👰🏼‍♀️🤵🏽💍 #July10 #married

Came home from a weekend away to find that my amazing fiancé @modeguise had planted foxglove in our front yard. Anyone who knew my Dad knows how amazing this is #digoxin

[Marc-Olivier Deguise @modeguise]

Just like that, my better half becomes a neurologist, during one of the most challenging year of her life. She’s so strongest, most determined and intelligent person I know. She is most deserving of this achievement and so so happy for her! Congrats @NaomiNiznick, you are amazing

[Naomi Niznick, MD FRCPC @NaomiNiznick]

Today I found out I passed my RC Neurology Boards. I am beyond relieved. This year has been traumatic to say the least. Studying for the RC while coping with a parent at the end of life was not easy. On April 8, I walked out of day 2 of my exam to find out that my Dad had died.

@AirCanada Sadly, ended catching her flight back and luggage sitting at the airport (never sent to her during trip), found just in time to check them back in to go home … @NaomiNiznick

[Marc-Olivier Deguise @modeguise]

what a disaster.. meanwhile partner has no clothes for her bachelorette, what supposed to be happy weekend..used to love this company to fly but seems like customer service is not par as what it used to be @AirCanada #CustomerService

[Marc-Olivier Deguise @modeguise]

@AirCanada I have been astonished by the lack of customer care both at luggage claim and customer service. I call luggage claim X3 with 1+ hr wait each time and call dropped x3. How can a call drop just like that ? Call customer service with 2:30 hrs wait time and can’t help…1/2

Great work from former lab !

Great start to #PASmeeting 2022. Looking forward to hear more about the great research done by other attendees and speakers in the next few days! At times - wish I could be at two place at once!
