Dr. Melika Loriamini! 

This new award, in honour of Dr. Dana Devine, supports early career scientists in a field related to transfusion science and medicine, blood banking and blood biotherapies. It is awarded in collaboration with the Canadian Society for Transfusion Medicine’s at their annual conference. 

“I truly appreciate the Committee for the recognition and I'm so proud that I'm the first person to win the Dana Devine Award,” Dr. Loriamini says. “When I walked into the conference, I felt like I was famous because everyone knew who I was. It was a great feeling that all the work, all the hard work, during these years that I did, it's now acknowledged, and everyone knows it.” 

Dr. Loriamini began her career in medical laboratory science in Iran, obtaining a Bachelor of Science degree before immigrating to Canada. She completed a second Bachelor’s degree, this time in biomedical science from York University, and went on to enroll in the laboratory medicine and pathobiology PhD program at the University of Toronto. While completing her education, Dr. Loriamini worked as a Medical Laboratory Technologist at LifeLabs and the William Osler Hospital. 

As part of her PhD, Dr. Loriamini worked with Canadian Blood Services Senior Scientist Dr. Donald Branch which she says allowed her to “acquire expertise in the fields of transfusion medicine and immunology and we were able to publish various articles.” 

In fact, it was Dr. Branch who first sent her the application for the award and told her he thought she was a strong candidate. 

“I want to say thanks to Dr. Branch, who was my supervisor. Actually, thank you is not enough,” Dr. Loriamini says. “He taught me how to think as a scientist and how to become a scientist. I truly appreciate him. He always trusted me.” 

Dr. Loriamini’s research focused on developing a new drug to help people who have autoimmune cytopenias — a cluster of conditions which causes your immune system to attack your own healthy blood cells. She was able to identify a potential drug which is expected to undergo clinical trials in the future.

In addition to receiving the Canadian Blood Services Dana Devine Award, Dr. Loriamini has also been recognized with the Canadian Blood Services Graduate Fellowship Program award in 2019 and 2021, the AABB Outstanding Abstract Award for Trainees as a Fellow/Post-Doctoral Student in 2022, the SGS travel award from the University of Toronto in 2022, the Best Poster for Translation/Basic research award from Hematology Academic Day in 2023, and the Best Poster for Infectious Diseases, Inflammation, and Immunology award from the 2023-Laboratory Medicine & Pathobiology Research Conference. 

Dr. Loriamini is now a Clinical Practice Leader at Humber River Health in Toronto which allows her to bring her research to a clinical setting. Congratulations Dr. Melika Loriamini!

The opinions reflected in this post are those of the author and do not necessarily reflect the opinions of Canadian Blood Services nor do they reflect the views of Health Canada or any other funding agency.

Our partnership with the Centre for Blood Research (CBR) at the University of British Columbia is helping to train the next generation of researchers in transfusion science. This blog post highlights just some of the achievements in education, training or knowledge mobilization accomplished by CBR trainees.   

Canadian Blood Services 2024 Lay Science Writing Competition offered in partnership with the Centre for Blood Research (CBR) provides research trainees an opportunity to exercise and enhance their science communication skills by sharing their research with lay audiences. The competition was open to research trainees in the broad Canadian Blood Services research network – including trainees that are directly funded by Canadian Blood Services, in laboratories that receive funding from Canadian Blood Services, and at the Centre for Blood Research in Vancouver. In this blog, graduate student Mahsa Yazdanbakhsh, author of the third prize-winning entry, provides some behind-the-scenes insights into the preparation of her submission. The full entry text is also shared below.  

Why did you choose to participate in the competition this year?  

I chose to participate in the competition because it gave me a chance to highlight important research in neonatal blood transfusion, specifically focusing on umbilical cord blood (UCB) transfusions for extremely premature newborns. I saw this as an opportunity to show how UCB could improve survival and outcomes for these vulnerable babies. Since I’m involved in this research, I felt it was important to share my insights and the potential benefits this work could bring to neonatal medicine. 

The theme this year was “Connecting science with society”; what did this theme mean to you?  

The theme was particularly meaningful to me because it emphasizes the importance of making scientific discoveries accessible and relevant to the broader public. For me, it’s about bridging the gap between complex research and real-world applications that can improve lives. In our work on umbilical cord blood transfusions for premature infants, the potential benefits go beyond the laboratory—they directly impact vulnerable newborns. This theme reminded me that research is not just about advancing knowledge within the scientific community, but also about ensuring that society understands and benefits from these advancements. By participating in this competition, I aimed to contribute to this connection, demonstrating how science can address critical healthcare challenges and ultimately improve outcomes for neonates. 

Did the writing process help you learn or discover something new about your research?  

Yes, the writing process helped me gain a new perspective on our research. It required me to step back and think about how to explain complex scientific concepts in a way that is clear and relatable to a wider audience. This helped me see my work from a different angle, focusing not just on the technical aspects, but also on the broader impact it could have on neonatal care. Writing about my research also reinforced the importance of effective science communication, reminding me that research isn't just about what happens in the lab, but how it can be applied to make a real difference in society. 

What tips would you share with others who are writing about research for lay audiences?  

When writing about research for lay audiences, I recommend simplifying complex ideas without losing the essence of the work. Break down the concepts into clear and simple language, but ensure key details remain intact. I suggest focusing on why the research matters by connecting it to real-world applications or benefits, helping readers understand its relevance. Avoid jargon whenever possible, and if you need to use technical terms, explain them in an accessible way. I also recommend using relatable examples to make complex concepts easier to grasp. Present the research in an engaging way, perhaps by telling a story or highlighting its human impact.

Evaluating umbilical cord blood transfusion efficacy and safety in neonates 

Imagine a small infant who was born prematurely and is having a hard time surviving in the outside world. These extraordinarily early newborns, referred to as ELGANs (Extremely Low Gestational Age Newborns), are born before 28 weeks of pregnancy and must fight a losing battle against anemia, a disorder in which there are insufficient healthy red blood cells in their blood to carry oxygen throughout their bodies. A common strategy used by physicians to win this conflict is blood transfusions. These transfusions now depend on adult donors' blood. This method, while life-saving, has limitations. Adult blood cells might not always meet these delicate babies' unique needs, which could occasionally result in complications and less positive results. But what if there was a more efficient method? 

Umbilical cord blood (UCB) has been proposed as a treatment for anemia in infants in the past. Fetal hemoglobin (HbF), a particular type of hemoglobin that is beneficial at carrying oxygen and protecting cells from harm, is rich in UCB. The fragility of fetal red blood cells and low volumes presented practical challenges that led to a decline in the use of UCB, despite its promising results. However, scientists are now looking again at this overlooked hero. They think that the secret to safer and more efficient treatments for premature babies may lie with UCB. According to recent research, UCB may be able to supply the necessary transfusions, and ongoing clinical trials are examining its advantages over adult blood.    

How to store UCB is a big obstacle when using it. UCB has a shorter life span than adult blood, which can be kept in storage for longer periods of time. Scientists are actively working on new methods to freeze and store UCB so it can be readily available when needed. This process is known as cryopreservation. Our research team has developed a meticulous method to freeze and thaw UCB. This technique, involving the addition and removal of a substance called glycerol, aids in protecting the blood cells during the freezing process. Having demonstrated the effectiveness of this method with adult blood, we are now adapting it for UCB.   

Our research is guided by three primary objectives: optimizing the freezing process, minimizing immune reactions, and assessing survival rates. By refining our freezing and thawing methods, our aim is to ensure that UCB cells remain healthy and functional. Furthermore, we seek to compare how the immune system responds to UCB and adult blood to ascertain the safety and efficacy of UCB transfusions. Lastly, we will evaluate the survival of UCB cells after cryopreservation and thawing, comparing them to adult blood cells. Success in these endeavors could offer a more potent treatment for anemia in premature babies, leading to improved health outcomes and fewer complications, thereby revolutionizing neonatal care and providing these vulnerable recipients with a stronger start in life. 

In conclusion, our research in Dr. Jason Acker's lab on UCB aims to address the critical needs of premature infants by optimizing cryopreservation techniques, understanding immune responses, and comparing the efficacy of UCB to adult blood. The potential benefits of utilizing UCB are immense, and if successful, this work could transform the landscape of neonatal transfusions, offering these vulnerable babies a better chance at a healthy start in life.

As the Principal Investigator for the SexMatters trial described in this blog, Dr. Mickey Zeller is an Associate Professor in the Department of Medicine at McMaster University. She is also a Medical Officer at Canadian Blood Services. 

Around 2018, Dr. Mickey Zeller's grandmother asked her a question that she couldn’t fully answer at the time. It’s a question that Dr. Zeller continues to keep top-of-mind in her roles as an Associate Professor at McMaster University and a Medical Officer at Canadian Blood Services. Having sustained a pelvic fracture at the age of 94, she asked her granddaughter, “If I need a blood transfusion, could it come from a man... and if it does, would that be safe?”. As Dr. Zeller describes, “I looked at her and, in that moment, I said, ‘Grandma, no one knows! But it’s on my list to find out!’.” 

In fact, questions about whether selecting products based on the sex of donor and recipient could improve outcomes following blood transfusions have been around for years. However, there is not yet been enough evidence to definitively answer whether this strategy would help optimize hospital and blood operator practices.

After much perseverance, collaboration with researchers across Canadian Blood Services’ extended research network, and a successful bid for CIHR funding, a research team led by Dr. Zeller is embarking on a new research journey they hope will finally provide the evidence to answer questions about whether sex matters in red blood cell transfusion.

What will the study focus on and why is it needed?

When a patient requires a transfusion of red blood cells (RBCs), the matching of product to patient is based on compatibility testing that looks at whether the blood is group A, B, AB or O, whether it is Rh positive or negative, and what other antibodies are present. Canadian Blood Services’ Rare Blood Program also helps ensure patients with specific combinations of antigens – proteins that appear on the surface of red blood cells – can be matched with appropriate blood components. Laboratory studies on donor factors such as age and sex have looked at their impact on characteristics of RBCs in terms of hematocrit, cell volume, hemoglobin content, and deformability – that is, the flexibility or “squeeze-ability” of the cells. However, currently available evidence has not demonstrated a need for red blood cells for transfusion to be matched based on the sex of either donor or recipient. 

The principal research question being posed by this study is: In adults admitted to the ICU who require RBC transfusions, do donor-recipient sex-matched RBC transfusions result in improved 30-day mortality compared with sex-mismatched RBC transfusions? Answering this question has a large potential for impact because of the substantial number of blood transfusions that occur throughout Canada every year.  

“If there was a risk identified [from the sex of the donor and recipient], even moving the needle a little bit to improve the matching of blood product to recipient could add another layer of safety to current practices,” Dr. Zeller explains.  

What had to happen to make this study possible?

While it seems like a basic question to remain unanswered, Dr. Zeller acknowledges the investments of energy, expertise, and funding to get the study to this point.  

“Sometimes these basic questions remain for a long time because it is challenging to get the funding and infrastructure in place to be able to answer them in a scientifically rigorous way; even if they’re basic-level questions, it’s only by investing that you are able to gather the evidence to answer the question.” Dr. Zeller says.

That’s part of the reason why Canadian Blood Services’ investments in networks like CTTG are important. The Canadian Transfusion Trials Group (CTTG) is funded by Canadian Blood Services with the aim of supporting and accelerating clinical trials that can inform best practices in transfusion medicine in Canada. CTTG reviewed and endorsed this SexMatters study and provided support through its development, making it the second RCT since CTTG’s inception to earn CIHR funding following participation in their review process.

"I had the opportunity to present to CTTG twice and receive feedback that improved this study design and my application to CIHR for its funding. Having it reviewed by people like Dr. Donald Arnold, Dr. Jeannie Callum, Dr. Nadine Shehata – people with world-recognized expertise in this area – really led to the success of this application,” Dr. Zeller says. “We were able to have really rich discussions on tough questions about study design and impact, including details like how we would account for patients that are pre-transfused entering the study.”

Says Dr. Zeller, “Each time the application went through reviews, I could present to these colleagues to essentially say, 'Here are the criticisms it has received and here’s how I’ve handled them.' And they would provide me advice and encouragement to resubmit. It is really valuable having people across the country who are cheering for you, and who are hand-in-hand with you to celebrate your success!”

“It’s an absolute privilege to do high quality research because you have to be surrounded by an incredible group of humans. Academic curiosity and commitment by those that have mentored me have enabled me to do this work. It’s out of a generosity of spirit that people have shared their expertise with me for this work, and it takes a lot of time and effort.”

What other research has informed this study? 

Before this study received CIHR support, the research team undertook an exploratory analysis, a systematic review and meta-analysis, and a pilot trial which took place in 2022 across five Ontario-based hospitals to establish feasibility of the randomized controlled trial. Findings of retrospective observational studies indicated potential association between sex-mismatched transfusions and mortality, but some aspects remained unclear due to low certainty of evidence, inconsistencies or contradictory subgroup analyses in the available literature.  

Much previous research involving Canadian Blood Services researchers has also supported the need for this randomized controlled trial. This includes: 

• research undertaken in the lab of Canadian Blood Services Senior Scientist, Dr. Jason Acker, which has investigated impacts of various factors (including age and sex) on red blood cell storage and other factors of quality;  
• the iTADs clinical trial (short for “An innovative Trial Assessing Donor Sex on Recipient Mortality") undertaken by Canadian Blood Services Adjunct Scientist Dr. Dean Fergusson and colleagues that signalled there may be increased risks with blood from younger, female donors; 
• as well as research by Canadian Blood Services Adjunct Scientists Nancy Heddle and Dr. Donald Arnold at McMaster University’s Michael G. DeGroote Centre for Transfusion Research (formerly known as the McMaster Centre for Transfusion Research) which was supported through Canadian Blood Services’ Transfusion Medicine Research Program Support Award.  

Earlier publications involving these and other researchers have also investigated the impact that blood donor age and sex have on outcomes for transfusion recipients, summarized evidence related to sex-matched versus mismatched transfusions and mortality, and the biological mechanisms implicated in adverse outcomes of sex-mismatched transfusions. There is still room for more investigation to build on this previously completed research, and that aligns with Canadian Blood Services' emphasis on the importance of research that spans the continuum from bench-to-bedside to continuously improve our processes, products and services. As Dr. Zeller describes: “There are biological studies and retrospective data, but we only have one existing RCT. There’s a real importance to pursue a prospective, RCT so we can look forward as opposed to looking back.”

“As every blood donor is unique, the challenge we have is to understand which donor-specific factors can be better matched to improve patient outcomes.  Differences in the biology of blood cells from male and female blood donors are well defined, but what we do not understand is if these differences affect health outcomes in transfused patients.  This is very important question that the SexMatters clinical trial is proposing to address.”

How will the study work and why the focus on transfusions in the ICU?  

Focusing on transfusions in the ICU is a significant distinguishing feature of this study. The iTADS trial was completed as a multicentre, double-blind trial, but it looked at mortality rates across the whole hospital. This new trial will look at transfusions received by patients in the intensive care unit (ICU) specifically. 

“In the hospital, we know that mortality rate is much higher in a transfused ICU patient compared to a patient in another part of the hospital,” Dr. Zeller says. “We’ve chosen to focus this study on the sickest population of patients – those in the ICU – with the idea that any impact will be seen most prominently in this group. The analysis will include consideration to dosage so we can adjust for the specific number of units transfused to each patient.” 

The study is also designed so that participants will not know whether a blood transfusion is matched or mismatched based on the sex of donor or recipient – a method used to prevent potential bias in the trial. 

“At the hospital, you always get a list with each shipment of blood product that says what units you have received from the blood operator”, Dr. Zeller explains. “As part of this study’s protocol, participating hospitals will see an additional colour-coding noted on this inventory, and this is what will be used when it comes time for us to do our analysis.”  

Who could benefit from this knowledge and what are the next steps?  

Dr. Zeller is glad to have Canadian Blood Services involved in this research, acknowledging that changing policy related to matching of blood products would be a significant change for hospitals and blood suppliers, requiring strong evidence from RCTs like this one.  

“This study will help to inform health-care professionals who prescribe and administer blood products, along with patients, donors, and the blood operator, too. One of the important questions if it does turn out to have a significant difference is ‘Then what?’ We already divide our inventory by group (ABO) and by Rh status (+/-). Would the need to be matching by sex further impact inventory? We don’t know yet, but that’s why it’s important to have the blood supplier involved,” Dr. Zeller says. 

The study will require a total sample size of approximately 11,000 patients across an expected nine hospital sites in Ontario.  

“We’ve designed this study to be very efficient; it’s got components of what would be considered a pragmatic study design,” Dr. Zeller says. “In terms of the products, Canadian Blood Services does not have to provide anything different than they already do for this study (other than the colour-coded markers) and we will use electronic capture to pull data, so we don’t need to collect study information at bedside. These were processes leveraged from the earlier iTADS study as the iTADS research team was very supportive of us learning from what they did.”  

“Whether transfusions should be matched for donor sex is a question that has been percolating in people’s minds for many years. Dr. Zeller has had the courage and perseverance to tackle this important question, which could have important policy implications.  I’m excited for Dr. Zeller to embark on this journey and advance knowledge on best transfusion practices.”
