When you wish upon a star
Makes no difference who you are
Anything your heart desires
Will come to you.

From: Pinocchio (1940), Walt Disney Pictures. Sung by: Cliff Edwards

The idea of allowing students to determine and design their own educational experiences may seem counter-intuitive to many, including students themselves. It’s certainly not easy to implement. However, setting aside the initial reaction and obvious practical issues, what eventually emerges is the realization that this is an approach with potential to bring out the best in the motivated student, extend the educational experience far beyond the traditional paradigms, and model the sort of life-long learning we’re hoping to ingrain in all our students.

“Self-directed learning, in its broadest meaning, describes a process in which individuals take the initiative with or without the help of others, in diagnosing their learning needs, formulating learning goals, identifying resources for learning, choosing and implementing learning strategies and evaluating learning outcomes.”  (from: Knowles, M. S. 1975. Self-directed learning: A guide for learners and teachers, Prentice Hall, Englewood Cliffs, New Jersey).

For those who require further convincing, I’ve asked Alyssa Louis, one of our Meds ’16 students to provide a guest blog this week. With the help and cooperation of Clerkship Director Andrea Winthrop and assistance of Clerkship Coordinator Jane Gordon, Alyssa arranged to undertake a rather unique elective experience during her Clerkship, pursuing an interest (perhaps “dream” or “obsession” would be better descriptors) she’s had for some time. As you’ll see as you read on, that pursuit has been very valuable and promises to pay huge dividends as her very promising career unfolds. And so, in Alyssa’s words…

Everyone I’ve worked with, spoken to or passed quickly in a hallway in the past 6 months has heard, at least on a few occasions, about my upcoming aerospace medicine elective. I was over the moon with excitement and probably made a few too many bad puns. However, before I launch into my personal experiences, I should explain that Aerospace Medicine is a sector within occupational health and preventative medicine that aims to preserve the health, safety and performance of individuals involved in air and space travel. Specialists, also known as “flight surgeons” must also be experts in delivering care in extreme environments, as many analog training missions occur at deep sea, high altitudes, remote deserts and polar locations.
This past July I participated in the Principles of Aviation and Space Medicine short course offered by the University of Texas Medical Branch (UTMB) as affiliated with the National Aeronautics and Space Administration (NASA.) The course, which is offered to final year medical students, residents and practicing physicians is run by UTMB faculty, many of whom have held the impressive titles of NASA flight surgeon or are acting medical directors for commercial space companies such as Virgin Galactic and Space Adventures.
In order to understand the unique health considerations for astronauts, we learned the basic physics and physiology of launching into space. Given that our millions of years of evolution selected human traits for life in earth’s gravitational field, it is truly remarkable that humans are able to adapt to life in space. Some of the many physiologic stressors include high G-force exposures of launch and landing, exposures to microgravity, galactic and solar radiation, circadian disruptions, noise exposure, carbon dioxide exposure, stress and isolation.

Twice flown astronaut and physician Dr. Michael Barratt gave us an overview of the physiologic adaptation and maladaptation to spaceflight, including the important responses of the neurovestibular system, caudal fluid redistribution, blunting of autonomic responses, and of course the concerning loss of bone density and muscle mass. In order to counteract this loss, astronauts aboard the international space station train for approximately 2 hours every day. The challenge of creating weight-bearing exercise in a weightless environment is achieved with bungee straps and vacuum cylinders, which make for a surprisingly high fidelity training experience. Though I had worked up a fair appetite, I was not able to sample the “just-add-water” nutritionist-designed and astronaut approved freeze-dried shrimp cocktail or steak in a pouch.

We received the historical perspective on aerospace medicine in a lecture by Dr. Charles Berry, a NASA flight surgeon during the Apollo and Gemini missions. At the tender but not subdued age of 92, Dr. Berry certainly did not withhold his objections to his Hollywood portrayal in Apollo 13. I got to sit in Dr. Berry’s old desk at mission control, the very same room where the moon landings were directed.
blog65-img3Back on earth, Aerospace Medicine also encompasses health maintenance and medical flight certification of airplane pilots. There is a truly complex relationship between pilot health and safety, and as we learned first hand in the full motion flight simulator, even perfectly healthy medical students can have vestibular mediated spatial disorientation leading to fatal crashes. We also learned the physiologic effects of airplane decompression, and its impact on time of useful consciousness through an altitude chamber run to 7620 metres (25,000 feet.) I thought fleetingly of Dr. Moffat’s respiratory physiology lessons as we reached atmospheric pressure of 276mmHg and my O2 saturation plummeted to 63%.
Now that I’m back home at Queen’s, I am looking forward to continuing to share my experiences with the rest of our community. I was extremely pleased to learn from a fellow tricolour, Queen’s emergency medicine graduate Dr. Christian Otto who is currently acting as a United Space Research Association principal investigator for the ocular health project with NASA. I will remain deeply grateful for the opportunity to blend my passions for medicine and physiology at environmental extremes. Of course, none of this would have been possible without support from Dr. Winthrop, Dr. Hollins, Jane Gordon and the UTMB faculty. Thanks Queen’s!
Did you know that…
  • Aboard the ISS, the sun rises every 90 minutes. And you thought your on-call room was a bad place to get a decent night sleep! In fact, one of the major challenges being addressed right now is circadian rhythm modulation for crew health.
  • CPR is very challenging in space because classic compressions would essentially push the operator across the room rather than pump the patient’s heart. The current literature suggests that the most efficient delivery is in the handstand position with feet braced against the ceiling.
  • Above 19.2km (63,000 feet) above sea level, the boiling point for water is approximately 37 degrees Celsius. One individual who survived exposure to this pressure described the feeling of saliva boiling off his tongue. Full pressure suits are required for survival above this altitude.
  • Astronauts train for their space walks in a massive swimming pool called the neutral buoyancy lab. There are mockups of the ISS underwater for astronauts to practice repairs.
  • Aboard the international space station, the main source of potable water is recycled urine. This water is used for drinking and rehydrating freeze-dried meals.blog65-img4
  • The current price tag to visit space as a commercial spaceflight participant is approximately $20 million dollars. This would not be covered on the average line of credit. The first Canadian to do so was Guy Laliberte, co-founder of Cirque du Soleil.

Medical school should be a place where students not only learn the “knowledge, skills and attitudes required of a physician”, but are also inspired to grow individually, gain self-awareness, pursue their own goals and develop their particular talents and interests in a way that will allow them to make unique, unanticipated contributions to society and to the profession. Alyssa’s story is a great example of what can happen when we work together with our students to go “outside the box” and make the extra effort to make the difficult and unconventional possible. When they “wish upon a star”… we’ll find a way.

    Through my military training and post graduate education provided by the Royal Canadian Air Force, I’ve been fortunate enough to have been exposed to Space in the Military realm:. Most recently at US Air Force Space Command in Colorado Springs CO. Through this experience I’ve met and heard Canadian and U.S. astronauts, engineers and space medicine specialists.

    These are very dynamic, highly motivated and passionate individuals who are contributing vital knowledge that future generations of humans will rely upon to explore Space.

    It appears that Alyssa has many of the pioneering traits that individuals working in Space possess. Given her passion, I sincerely hope that Alyssa pursues her passion and contributes to the knowledge of Space Medicine. This is vital as humans look to colonize planetary bodies such as the Moon and Mars.

    Credit also to the Faculty of Queen’s Medicine for allowing/helping students to pursue their passions.

    I wish Alyssa well in whatever path she chooses.
