James Stempien (MD) has navigated some of the most challenging corners of emergency medicine, from the frigid isolation of Inuvik to the bustling corridors of Saskatoon’s emergency departments. His experience in low-tech outposts has shaped his approach to modern emergency care. “When things aren’t going well you see it in the emergency department first,” Stempien said. “We’re the front door. We’re always open.” As provincial department head of emergency medicine, Stempien sees patients on their worst days in hospitals bursting at the seams, struggling to...

As the world aims to eradicate hepatitis C (HCV) by 2030, Carrielynn Lund and Dr. Alexandra King’s team created a how-to guide. is a step-by-step guide to tackling a spike of new infections across the three Canadian prairie provinces. Hepatitis C (HCV) causes severe liver disease, and was notoriously difficult to treat until the introduction of direct-acting antivirals a decade ago — antivirals which boast a remarkable 95% success rate. Despite this advancement, Lund and Dr. King say Saskatchewan, Alberta and Manitoba need to know why HCV cases keep rising, particularly in...

Brianne Philipenko (MD) was midway through her respirology fellowship in Calgary when the Covid-19 pandemic shut down the city. She started interval workouts at home using Nike’s fitness app — when inspiration struck. “Coming up with a creative, innovative way to allow people to access an exercise program outside of the typical organized pulmonary rehabilitation in a gym setting was something that I became really interested in,” said Philipenko.. As a respirologist, Philipenko was already frustrated by the lack of ‘mainstay’ guidelines on incorporating exercise...

In this episode, we gain insight into Dr. Sarah Forgie, the new Dean of the College of Medicine. She discusses her innovative teaching methods, her career as a pediatric infectious disease specialist, and her vision for advancing Saskatchewan’s College of Medicine. Dr. Forgie also shares the story behind her decision to learn the ukulele. Born to family physicians, Dr. Forgie grew up in Lynn Lake, Manitoba, a remote fly-in mining community. Her family later relocated to Winnipeg, where Dr. Forgie credits much of her motivation to her mother, who encouraged her to pursue both medicine and...

A behavioural neuroscientist in Saskatoon is uncovering marijuana’s effects on fetal brain development. After recently winning a five-year CIHR grant of $960,076 in the spring of 2024, Dr. John Howland’s lab at the University of Saskatchewan is expanding its work examining prenatal exposure to cannabis smoke. Howland’s teams will assess the way cannabis exposure alters higher brain functions like memory and learning in both rats and mice. Compared to cannabis injections in the past, the professor of Anatomy, Physiology and Pharmacology at the College of Medicine said exposing...

Growing up in Columbia had a profound impact on Dr. Juan-Nicolas Pẽna-Sànchez. In this episode, hear why the former family physician pivoted, becoming Saskatchewan's lead in finding the best ways to treat Crohn's disease and ulcerative colitis in rural and Indigenous patients. Even as a teenager, Juan-Nicolás Peña-Sánchez could see stark differences in health for those who had medical coverage — and those without, thanks to his stepfather, an emergency department physician. “I used to go with him sometimes on shifts to learn and shadow him,” said Peña-Sánchez said. “The...

"When I got into medical school, the last thing in the world I wanted to be was a surgeon because I couldn't stand the sight of blood," said Dr. Mike Moser. Fast-forward to the present day, where Moser is now one of Saskatchewan's top kidney transplant surgeons, winning last year's Golden Scalpel Award for Pre-clerkship Education, the 2022 Logan Boulet Humanitarian of the Year Award, and numerous teaching awards. In this episode, the professor of general surgery at the University of Saskatchewan's College of Medicine takes us back to one pivotal day where everything changed, propelling...

As an undergrad, Daniel Fuller didn’t have a car, nor was he keen on taking the bus. “I rode my bike to university every day in the fall and then just kept on going and never stopped,” said Fuller, a former national and international canoe/kayak athlete. As he pedaled, Fuller watched the way people used trails, sidewalks and roads. “I really started to get into active transportation, how people move around cities and how we can get people active -- outside of the sport environment,” said Fuller, now an associate professor in Community Health and...

From the laboratory to saving lives, this episode brings together three outstanding researchers from the University of Saskatchewan’s Department of Anatomy, Physiology, and Pharmacology (APP) as they discuss their work and its implications for cardiac care. Dr. Michelle Collins, Dr. Scott Widenmaier, and Dr. Changting Xiao are all recent recipients of research grants from Heart & Stroke (formerly the Heart and Stroke Foundation of Canada). In Canada, one per cent of newborns have congenital heart defects. Thanks to advances in cardiac care, up to 85 per cent of these...

"Pushing politicians to do what is good for the health of the people, there's no way around it," said Dr Jacob Alhassan. Born and raised in a rural Ghanaian village, Alhassan grew up without electricty and paved roads. He watched women die in childbirth. He grew resentful of health systems that left the poorest people to fend for themselves, while the rich thrived. Alhassan decided to take action. At first, he thought he would study hard to become a local hospital administrator. Partway through his university years, Alhassan began to dream even bigger. In this episode, he looks back at his...
info_outlineLike a lot of kids, Anurag Sakharkar used to dream about being a doctor, or an astronaut. His parents, both academics, encouraged him to follow his dream.
In high school, he began spending evenings and weekends working at the University of Saskatchewan’s biomedical labs, perfecting advanced research methods, western blots and PCR analysis . He began learning about Parkinson’s disease with Dr. Changiz Taghibiglou, then started examining novel cancer treatment approaches with Dr. Franco Vizeacoumar.
The Covid-19 pandemic brought Anu’s in-person laboratory time to an abrupt halt. Undeterred, he began to spend his nights poring over gene expression data, using computational analysis to identify patterns.
“We integrated all these different methods and looked at the genome coordination as a whole,” said Anu. “What important pathways are involved, and how do they connect and interact at the DNA, protein, and RNA levels?”
His curiosity spread from analyzing biomarkers in cancer cells — to learning more about the dramatic changes occurring in an astronaut’s body during space flight.
Astronauts lose bone density and muscle mass in space. They endure neurological degeneration, renal and cardiovascular dysfunction, compromised immunity, and upon their return to earth they have a far higher risk of developing cancer. Anu noticed a more large-scale inherent change in these astronauts in his research.
“You see gene correlation and coordination breaking down all over the entire genome,” said Anu. “You have a huge systemic trauma that's occurring in these astronauts when they go into space.”
Together with Dr. Jian Yang from the College of Pharmacy and Nutrition, Anu started analyzing astronaut gene expression data gathered in NASA’s open-source GeneLab. It tracked eight men and two women posted to the International Space Station for a six-month period, including pre-flight, inflight, and postflight measurements.
Anu developed a novel expression analysis method, and has now identified 32 genes with outsized effects on astronauts’ health as possible candidates for biomarkers to characterize, monitor, and even treat health issues.
In February, his research was published in Life. With support from the University of Saskatchewan President’s NSERC Research Fund, it also formed a partial basis of Anu’s honours thesis as he completes his final undergraduate year this spring, majoring in Cellular Physiology and Pharmacology.
He’s developed partnerships with universities around the world, along with NASA, the Canadian Space Agency, and private space bioscience companies.
“Space is definitely humanity’s future,” Anu said. “That future is getting closer and closer."
