International effort leads to better clinical guidelines for a serious illness affecting fetuses and newborns

What is Fetal and Neonatal Alloimmune Thrombocytopenia?

FNAIT is a rare disease that occurs when a baby inherits platelet proteins from its father that are foreign to its mother. In response, the expectant mother’s immune system makes antibodies that destroy the developing baby’s platelets. Platelets circulate in blood and help prevent bleeding. When a fetus’ platelets are destroyed, the number of platelets in their blood is reduced (called “thrombocytopenia”), leaving the fetus vulnerable to bruising or bleeding. When bleeding occurs in the brain, FNAIT can become a devastating illness that leads to brain damage or death.

Why does this sound familiar?

Perhaps you have a good memory! There was a R.E.D. blog post in June 2017 about an earlier systematic review to determine the safest antenatal (before birth) treatment for FNAIT, which you can re-visit to learn more about this disease. That review found that treating the mother with intravenous immunoglobulin (IVIG - a solution of concentrated antibodies purified from donated plasma) was safer for the mother and fetus than more invasive treatments.

Or you may have heard of a more common disease called Hemolytic Disease of the Fetus and Newborn. This similar disease occurs when there is an incompatibility between a mother and father’s blood type, which leads to destruction of the baby’s red blood cells. Hemolytic Disease of the Fetus and Newborn is the reason women’s blood type is checked during pregnancy. Some women whose babies are at risk of this disease can be offered Rh Immune globulin (or “anti-D”) injections to protect the baby.

What is new now?

The same group that performed the systematic review in 2017 has published a new guideline in British Journal of Haematology. In total, this group has now completed three systematic reviews related to the management of FNAIT: one looked at antenatal (before birth) management of FNAIT (published in Blood); one looked at postnatal (after birth) management of FNAIT (published in The Journal of Perinatology) and the third examined the value of diagnostic tests in FNAIT (published in Vox Sanguinis). 

The new guideline has 22 recommendations. The guideline group development team found that it is better to treat babies born with low platelets with whatever platelet product is available. It had previously been thought that these babies should receive matched platelets, but while matched platelets will work better, if they are not immediately available, it is better to begin treatment with whatever platelets are available than to wait. 

Who are these guidelines for?

These guidelines provide doctors with evidence-based information that will help mothers and their babies benefit for the best pre- and post-natal care available for FNAIT. To ensure these guidelines are disseminated broadly and appropriately used, the ICTMG also developed resources for physicians to accompany the guidelines. These include a podcast about the guideline for physicians, a PowerPoint presentation and treatment algorithms. The ICTMG also developed patient pamphlets in seven languages and a podcast about FNAIT for patients.

Where can I learn more?

You can learn more about FNAIT on the ICTMG website, where you’ll find links to all the physician and patient resources mentioned above. Naitbabies.org, a patient organization run by families affected by FNAIT, also provides a lot of valuable information. You can also learn about research conducted by the Centre for Innovation to help understand FNAIT and uncover new treatments for this disease here.

Trainees shine at the 2019 Norman Bethune Symposium


Tuesday, June 11, 2019

This annual symposium honours Canadian physician, Dr. Norman Bethune. A controversial figure, Dr. Bethune is remembered as a fearless doctor, an innovative biomedical engineer, an early proponent of socialized medicine, and a trailblazer who operated the earliest practical mobile blood banks. Reflecting his legacy, the Norman Bethune Symposium offers a platform for researchers and clinicians to present strategies and challenges experienced within transfusion medicine.

The program for this year’s symposium was developed by Dr. Dana Devine, Canadian Blood Services’ chief scientist, and Dr. Edward Conway, Centre for Blood Research director. The agenda struck a balance between providing well-established experts the opportunity to present their work and showcasing trainees and early-career investigators. As Dr. Devine noted, the symposium has much to offer trainees: it provides “a chance to reunite with friends and colleagues, and encourages networking opportunities for trainees, including the opportunity to meet high-profile investigators, which can be particularly valuable for trainees and those early in their careers”.

Trainees presented an impressive six talks and 20 posters on topics ranging from the ethical debate around paid plasma donations to innovative materials to stop bleeding in trauma patients. In this post, I'll focus on the excellent contributions of trainees. Visit the Centre for Blood Research blog to read about the day's invited talks.

Researching the ethics of commercial plasma donation

Kelsey Johnson, a social scientist and PhD candidate from the department of geography at the University of British Columbia presented research she is conducting in partnership with Canadian Blood Services and the Centre for Blood Research on the ethical debates surrounding the history of commercialization of donor plasma. Kelsey is a recipient of the prestigious UBC Public Scholars Award, which supported a four-month research term in Atlanta, Georgia, during which she studied the history of paid plasma by trawling through media archives. Her findings highlight the shifting public perception and stigmatization of paid plasma donors in the southern US over the past several decades, research that is particularly relevant as the debate over paid plasma continues to play out in Canada.

Innovative research to better manage bleeding

Over coffee during the trainee poster session, I chatted to graduate student, Wayne Zhao (Devine Lab, University of British Columbia), who has attended three Centre for Blood Research symposia since he began his graduate studies. He commented on why he keeps coming back: “These symposia are a great platform for research trainees to receive input from researchers in different disciplines. This allows you to expand the horizons of your own research.”

Wayne, who is funded by the Canadian Blood Services’ graduate fellowship program, is researching cold-stored platelets. Platelets are usually stored at room temperature, because when exposed to cold, platelets become activated and are quickly cleared from the blood circulation once transfused. Recently, however, there’s interest in using cold-stored platelets as an alternative product for patients with massive trauma. Transfusing already activated platelets may be an advantage in helping those patients clot faster and prevent further blood loss. Wayne is testing the characteristics of cold-stored platelets in the laboratory, to better understand how they might behave in patients.

Trainee Massimo Cau (Kastrup Laboratory, University of British Columbia) is taking a different approach to preventing bleeding. He is using a novel technology self-propelling particles that drive drugs directly into the wound to stop deadly bleeds. He hopes they may be used to treat challenging or difficult-to-reach bleeds such as stomach bleeds. Using a model of upper gastrointestinal bleeds in pigs, Massimo found that treatment with self-propelling particles halted bleeding six-times faster than a similar treatment that is FDA approved.

Understanding red blood cells

Another recipient of a graduate fellowship from Canadian Blood Services, Emel Islamzada (Ma Laboratory, University of British Columbia) described a new method to monitor stored red blood cell quality. She is using a microfluidic device developed by the Ma Laboratory that sorts red blood cells based on how rigid or flexible they are a known marker of the cells’ quality. She hopes to use this method to find “super-storers” – blood donors whose red blood cell quality remains particularly high during the storage period.

Dr. Narges Hadjesfandiari, a postdoctoral fellow (Devine laboratory, University of British Columbia) used product quality control data from Canadian Blood Services to understand factors that influence the quality of red blood cells. She showed that the time to production (i.e. the length of time between collection of a whole blood donation and the production of a red blood cell component from that donation) is important. Red blood cell units that had a shorter time to production had lower hemolysis, indicating better quality. She is also investigating factors in donors that may impact quality.

Travel bursary awardee

Master’s student, Ahmed Al-Arnawoot (Dr. William Sheffield Laboratory, McMaster University) was the recipient of a travel bursary from Canadian Blood Services Centre for Innovation to attend the 2019 Norman Bethune Symposium. He presented a poster and talk describing new approaches to find therapies for auto-immune vasculitis. He engineered natural inhibitors to target an enzyme in neutrophils that may cause inflammation in blood vessels. Ahmed used several rounds of screening of phage display libraries (a technique that won its developers the 2018 Nobel Prize in Chemistry) to develop a library of peptide candidate inhibitors that mimic the natural enzyme in the body.

“I am happy to be here! It is great that there’s an opportunity for Canadian Blood Services trainees to travel to Vancouver and present their work. Presenting here has been a great conference experience; there are lots of opportunities for dialogue with many high-profile investigators in my field.” – Amhed Al Arnawoot, McMaster University

I've described here the work of the trainees who gave invited talks, but trainees contributed much more to the 2019 Norman Bethune symposium. Many trainees presented posters, and each one gave a 30-second summary of their research at a “shot-gun talk” session. The brief snapshots presented covered research ranging from age-related macular degeneration to factors that affect red blood cell lysis during storage.

To culminate a day filled with valuable networking and knowledge dissemination, poster award winners were announced: 3rd place went to Wayne Zhao (Devine Lab, University of British Columbia), 2nd to Aparna Gopal (Karsan Lab, British Columbia Cancer Research Centre), and 1st place to Emel Islamzada (Ma Lab, University of British Columbia). Congratulations to award winners!

Creating platelets 2.0: stronger, faster, and with twice the life-saving power


Thursday, June 06, 2019

The ability to genetically modify a cell is a powerful tool. Genetically modified cells have advanced our understanding of how the body works and how diseases develop. They are currently used as treatments for a range of diseases, from cancers to bleeding disorders. Yet not all cells are easily modified. This is true of small cells that are indispensable for stopping blood flow during injury. 

Stefanie Novakowski
Dr. Stefanie Novakowski

Why modify platelets? Platelets are currently used in the clinic to stop ongoing bleeding, caused by trauma or surgery. However, during severe bleeding platelets become dysfunctional, and these platelet transfusions no longer work. Correcting platelet dysfunction during trauma could be addressed by modifying platelets. For example, platelets could be engineered to produce proteins that activate clotting or stabilize blood clots after they form. Platelets are also given to patients with low platelet counts, which can be caused by a variety of factors, including certain cancers. While the platelets are given to patients to prevent bleeding, platelets also naturally interact and communicate with cancer cells. Modified platelets have the potential to deliver cancer-fighting materials to tumour cells, while also preventing bleeding. 

Unfortunately, commonly used methods for delivering genetic material to platelets either don’t work well or induce unwanted changes to the platelets. Currently, the best method for creating modified platelets is to modify the cells they develop from, called hemopoietic stem cells. These stem cells can be grown inside of a laboratory, modified, and then transplanted back into an individual. This approach has been used to treated inherited diseases. However, this method permanently changes a person’s platelets, and would not be useful in scenarios where only temporary modifications to the platelets are required, such as during active bleeding. Platelet BioGenesis, a company based in the United States, has recently developed a technology for growing large numbers of platelets from modified hemopoietic stem cells, but it will be years these laboratory-grown platelets can be used in hospitals. 

To address this problem, the Kastrup Laboratory at the University of British Columbia is taking a novel approach to directly modifying platelets. Using small, synthetic spheres called lipid nanoparticles, we successfully delivered genetic material into platelets without inducing unwanted changes to the platelets. By using specific lipids, or fats, to build the nanoparticles, we identified nanoparticles that deliver messenger RNA to the platelets. Like DNA, messenger RNA is a type of genetic material that is read by a cell to create new proteins. Unlike most cells, platelets do not have their own DNA, so genetically modifying platelets requires delivery of messenger RNA. 

Microscope images of platelets (red) that have taken up foreign genetic material (green). Adapted from: Novakowski et al: Delivery of mRNA to platelets using lipid nanoparticles. Scientific Reports 2019: 9; 552.
Microscope images of platelets - Stefanie Novakowski


By testing various classes of these nanoparticles, we determined characteristics of the nanoparticles that are important for uptake. These characteristics included a small size for the particle, and positive charge on its surface. Platelets treated with nanoparticles still had the ability to aggregate and spread, processes that are important to their ability to stop blood flow. We also found that the RNA taken up by the platelets was then released back out under certain conditions, indicating that modified platelets have the potential to be used a delivery vehicle for RNA-based drugs. This might be useful for creating cancer-fighting platelets, as RNA that promotes cancer cell death could be delivered to tumours by the RNA-treated platelets. 

Delivery of RNA to the platelets is only the first step in creating genetically modified platelets. To modify a platelet, the RNA has to be read by the cell, creating a new protein that alters the platelet’s function. Unfortunately, the RNA that we delivered could not be read by the platelets. To address this, we are now varying the composition of the nanoparticles, using different types of lipids to build the particles. This may alter where the RNA is delivered within the platelet and allow the RNA to be read by the platelets. Further experiments are also needed to see whether RNA-treated platelets can function once they are placed back into a patient. Currently, the platelets are modified after they have been isolated from whole blood from healthy individuals, and their function has only been assessed in a test tube. Whether these platelets still circulate and respond to signals within circulating blood remains to be seen. 

Platelets are involved in bleeding, cancer, and even immune and inflammatory disorders. The ability to directly modify platelets would extend our knowledge of platelet biology, and hopefully lead to improved therapeutics for a range of diseases. Platelet transfusions are already essential to treating bleeding. If researchers are successful in creating modified platelets that can be used in hospitals, there may be even more opportunities for platelets to act as a life-saving therapy in Canada and the throughout entire world. 

In January 2019, Dr. Stefanie Novakowski completed her PhD at the University of British Columbia in the laboratory of Dr. Christian Kastrup. There, she developed new tools for modifying platelets small cells found within the blood that are responsible for blood clotting. As a graduate student, Stefanie discovered a passion for knowledge translation, and the Canadian Blood Service's inaugural writing competition provided the perfect opportunity for her to hone her writing skills. Stefanie’s own work provided the perfect inspiration for her writing, since it was a story she knew but rarely shared outside of academia. Now that she has completed her degree, Stefanie hopes to start a career in science communication. 

The 2018 Canadian Blood Services Lay Science Writing Competition was organized by the Canadian Blood Services’ Centre for Innovation with welcome support from Science Borealis and the Centre for Blood Research at the University of British Columbia.

Iron deficiency in pregnancy – a matter of public health


Tuesday, May 28, 2019

Red blood cells are like delivery trucks. They deliver oxygen to the vital organs in our body. Iron is the flatbed of the truck which holds the oxygen in place. Iron is a key ingredient to build red blood cells and when you don’t have enough iron, your body doesn’t make enough red blood cells. This is called anemia. We get iron from the foods we eat such as meat, leafy green vegetables and legumes – all rich in iron.  Our body loses iron when we lose blood, so women are at the highest risk for low iron since blood is lost monthly during childbearing years.

Image
Heather VanderMeulen
Dr. Heather VanderMeulen of the University of Toronto. It takes the iron of 177 steaks to build a baby.

Imagine a woman’s iron stores as a bank account, and because of menstrual periods leading up to pregnancy most women enter pregnancy with low balances. Also, pregnancy itself is like taking out substantial iron withdrawals every day because it takes over one gram of iron to make a baby – that’s equivalent to 177 steaks! So, if the withdrawals are larger than the deposits, she empties her account and anemia develops, which puts the mother at risk for severe fatigue, difficulty concentrating, shortness of breath and postpartum depression. Also, without enough iron, a woman’s red blood cell count can drop dangerously low, prompting a blood transfusion.  For babies, iron deficiency anemia can be even worse as it leads to low birth weight, preterm delivery, delayed development, poor future academic performance and even early death. Luckily, treating iron deficiency in pregnancy is straightforward: it involves making regular small bank deposits with oral iron supplements or getting a big paycheck with intravenous iron.

Why is a blood transfusion particularly worrisome in women of childbearing age? It is because being exposed to someone else’s red blood cells can trigger a woman to make antibodies. These antibodies can then complicate a future pregnancy as they target and destroy the fetus’s red blood cells, causing potentially life-threatening anemia. So, iron deficiency in pregnancy is a big deal – it carries important risks to mother and baby for this and future pregnancies.

We wanted to know how commonly women are being transfused during pregnancy at our hospital and if they are being transfused for unrecognized, untreated iron deficiency anemia. In other words, we wanted to know how often women and their babies are being put unnecessarily at risk. To answer this question, we looked at all pregnant women transfused in the last 5 years and reviewed their medical records to see if they were tested and treated for iron deficiency. We also compared each woman’s results to those of an age-matched woman who was not transfused, because we wanted to know what differentiates the transfused women from the non-transfused women.

We found that transfused women were over 3 times more likely than non-transfused women to have uncorrected iron deficiency anemia. This highlights how important iron is for building red blood cells and avoiding blood transfusion. We also found that twin or triplet pregnancies and emergency C-sections both increase the risk of requiring a blood transfusion.

For example, consider Shelly, a 31-year-old woman with low iron stores before pregnancy who is now pregnant with twins. Her iron and red blood cell levels have been dropping throughout her pregnancy, and on the day of delivery both are very low. She has a normal vaginal delivery and loses a small amount of blood. The next morning, her red blood cell count is extremely low, and she receives a blood transfusion. Shelly started pregnancy with a low bank account balance. The daily withdrawals from her bank account were doubled (twins), and her deposits were insufficient to compensate. Iron deficiency anemia was a predictable and preventable outcome that should have been recognized early and treated with iron. Our goal is to target patients like Shelly.

Image
Blood transfusions to pregnant women
Blood transfusions to women of childbearing age can complicate future pregnancies.

Our research shows that 1 in 3 pregnant women did not have their iron levels checked. In women who were identified as being deficient, less than half were treated with iron. This highlights an important gap in prenatal care and we believe that this problem is not unique to our hospital. All women should have iron stores checked and their iron supplementation tightly managed throughout pregnancy. Unrecognized, unprioritized iron deficiency in pregnancy is a universal public health problem.

Understanding why women are being transfused in pregnancy helps us identify areas for improvement. Obstetricians are on the front lines and feeding this information back to them is key to addressing the under-recognition and under-treatment of iron deficiency in pregnant women. The next step is to empower obstetricians to identify at-risk women early and prevent iron deficiency anemia throughout pregnancy. If we can prevent empty bank accounts, we can minimize blood transfusions to a vulnerable patient population and prevent the development of antibodies that can complicate future pregnancies.

Dr. Heather VanderMeulen is a third year Internal Medicine resident and soon-to-be Hematology fellow at the University of Toronto. Under the mentorship of Dr. Jeannie Callum and Dr. Michelle Sholzberg, she has developed a passion for women’s health and hematology. Her goal is to improve the quality of care provided to women of childbearing age with hematologic disorders.

Canadian Blood Services’ scientist recognized for his mentorship of graduate students


Wednesday, May 22, 2019

Congratulations to Canadian Blood Services' Dr. Jason Acker, who was awarded the University of Alberta Graduate Students’ Association Graduate Student Supervisor Award at a ceremony on March 22, 2019. This award recognizes "those faculty members who excel in the supervision of graduate students”. What makes this award even more special – Dr. Acker was nominated by one of his graduate students, Ruqayyah Almizraq. We chatted to Dr. Acker to learn more.

Dr. Jason Acker
Dr. Jason Acker and Ruqayyah Almizraq at the University of Alberta Graduate Students’ Association award ceremony

 

Q: Tell us more about this award?

"I have been very fortunate to have had the opportunity to mentor and work alongside an outstanding group of graduate students over the past 17 years that I’ve been at the University. While the GSA Graduate Student Supervisor Award is intended to recognize faculty who excel in the supervision of graduate students, I think this award really recognizes the environment that we create to allow students to explore and grow as researchers. At Canadian Blood Services we have been very intentional in providing our scientists and clinicians with the resources and tools to create a supportive environment for our trainees to excel in transfusion science research. This award is a testament to our pursuit of excellence in training the next generation of transfusion scientists.”

Q: What makes this award so special for you?

“I am particularly humbled by this event as it was a student-nominated award presented by the Graduate Students’ Association which I received. To be nominated by the graduate program would have been great, but to be nominated and selected by the students is extra special!

I do not see myself as the wise man sitting on the mountain and the students as the seekers of knowledge or wisdom. I see myself as the experienced tour guide who has been fortunate to have traveled many of the back roads and trails of an interesting scientific discipline. While I may be worldly in my travels, I am not the world’s traveler and as such I do not have all of the answers nor have I come to my final destination. I enjoy traveling together with my students as I am a learner too!"

University of Alberta’s Timothy Caulfield receives James Kreppner Award


Tuesday, May 14, 2019

The 2018 Canadian Blood Services’ James Kreppner Award has been awarded to Timothy Caulfield, professor and research director in the Health Law Institute at the University of Alberta.   

Valued at $50,000, the award will support Professor Caulfield’s project to analyze the marketing practices of private cord blood banks, assess their claims, and consider how regulatory tools can help ensure services marketed are done in a scientifically informed and evidence-based manner.    

Image
Canadian Blood Services' James Kreppner Award awarded to Timothy Caulfield

“The entire Health Law Institute team is thrilled about this award, and we truly appreciate the opportunity to dig into the complex issues associated with donation, blood products and policy development,” says Professor Caulfield. “The research seems both timely and needed. We are lucky to have an award of this nature and hope our work will reflect James Kreppner's fearless analysis of controversial issues.”  

James Kreppner was a former board member of Canadian Blood Services, a lawyer, and a strong advocate for patients’ rights and blood safety. He suffered a severe form of hemophilia-A – a genetic disorder that makes it difficult for blood to clot, and his condition often required transfusions of blood products. In 1985, he became infected with HIV and hepatitis C through tainted blood products.  

Mr. Kreppner became a key figure in establishing the public inquiry into contaminated blood and testified twice before The Krever Commission. He was also a long-time volunteer and member of the Canadian Hemophilia Society before his passing ten years ago on May 14, 2009.   

This annual award named in his honour supports one high-quality research project that explores legal and policy questions relevant to the products and services provided by Canadian Blood Services. The award’s research priorities include the legal and regulatory aspects of (a) donation, collection, storage, and use of blood, blood products, and hematopoietic stem cells; and (b) organ and tissue donation and transplantation.   

Through a series of funding programs and research collaborations, the Canadian Blood Services’ Centre for Innovation conducts and supports research in key priority areas, including projects that span the translational continuum from “bench to bedside.”  

The 2019 competition for the James Kreppner Award will open for applications in Fall 2019 and will support one project with up to $50,000 for a period of one year.

Stories worth sharing: Blood clotting factor or clot buster?


Tuesday, April 16, 2019

Brought to you in partnership with the Centre for Blood Research, this week's Stories worth sharing is focused on research into a new class of anticoagulants.

Anticoagulants, or blood thinners, are medicines used to treat patients who experience unwanted or excess blood clotting. Between clotting and bleeding, there exists a delicate balance. If blood cannot clot effectively, the risk of bleeding increases. If blood clots too easily, there is a risk of heart attack, stroke and other serious conditions. 

Recent research being undertaken in Dr. Ed Pryzdial’s laboratory at the University of British Columbia is studying how some of these newer drugs affect the balance between clotting and bleeding.  The anticoagulants being studied are known to specifically target and inhibit a clotting factor called Factor Xa, as well as to decrease the formation of blood clots. 

While Factor Xa’s role in forming clots is well-known, its role in busting clots is much less well-established. In the Pryzdial laboratory they’ve found an additional way in which these drugs may help patients with too much clotting, by enhancing “clot-busting”. The process of clot busting (i.e., dissolving a clot once bleeding has been stopped), is an important way of managing clotting and associated risks. This work sheds light on how factor Xa will enhance clot busting—knowledge, which could be used to design more effective anticoagulant drugs in the future.

Winning science research writers announced


Friday, April 05, 2019

To give our research trainees an opportunity to showcase their research, while honing their writing skills, Canadian Blood Services teamed-up with Science Borealis and the Centre for Blood Research, to launch our first-ever Lay Science Writing Competition.


“It’s important for researchers to be able to explain what they do in an engaging and understandable manner to those who don’t work in research. This competition is a great opportunity for trainees to hone their skills in public science communication.”

Dr. Dana Devine

Canadian Blood Services Chief Scientist


Whether it was the chance to be published or the prizes, many trainees responded to the challenge, submitting entries that reflect a breadth of research in blood, plasma, stem cells, and organs and tissues. Within the competition theme of “Research that matters”, each entry was to describe the impact of their individual or lab’s research on the transfusion and transplantation system and/or on our society. A jury of professional communicators and scientists was given the challenging task of reviewing and judging the submissions on their writing and storytelling merits, assigning a ranking and selecting the top 3 science research writers.

…and the winners of the 2019 Lay Science Writing Competition are:

Nothing in science has any value to society if it is not communicated

Anne Roe, The Making of a Scientist (1953)


Much of the work supported by the Centre for Innovation is published as articles in scientific and medical journals. These journal articles are designed to be read and understood by other experts, so it can be challenging for anyone who is not familiar with the subject to glean valuable information. To bridge this gap and help make our research findings more accessible, the “Research Units” were developed.

How do Research Units help make the findings published in a scientific journal more accessible?

For a start Research Units are shorter. But they also provide a concise summary of the most important aspects of a study, asking: “What is this research about?”; “What did the researchers do?”; “What did the researchers find?”; and perhaps most importantly, “How can you use this research?”. Research Units provide details about the research team and information about the original journal article for the reader that wants to learn more. Scientific jargon, often a barrier to non-expert readers, is removed or clearly explained.

Fifty Research Units and counting

The first Research Unit was published in March 2013 and described a study by Centre for Innovation Engineer, Dr. John Blake, to understand how changes to blood manufacturing and distribution services would impact availability of blood products at hospitals. Dr. Blake’s work is also the subject of our 50th Research Unit, which was published just recently. This latest Research Unit, “One in a million: Modelling rare blood flow” describes a recent study with Canadian Blood Services associate medical director, Dr. Gwen Clarke, to help meet the needs of Canadians with rare blood. Drs. Blake and Clarke analyzed supply and demand for rare blood types and used simulation modelling to understand how to optimize the blood operator’s inventory of rare blood types to meet demand. The study showed that keeping a modest inventory of frozen rare blood types, combined with increased screening of donors for rare blood types, provides the greatest chance of ensuring that Canadian patients with rare blood have access to red blood cell transfusions when they need them.
