27 June 2023 (Tuesday) - BTLP-TACT Exercise(s)

Time for another BTLP-TACT exercise.

 

I had one case – an eighty-six year old woman in the out patients department who was tire all the time.

However the demographics on the sample label didn’t match the request. Not a single data item agreed. I rejected it.

 

So I had another go…a thirty-three year old woman in the out patients department requiring group and save for antenatal bleeding.

She grouped as O Rh(D) Positive with a negative antibody screen

 

Two green lights… Go me!!

26 June 2023 (Monday) - Transfusion News Update

 

The nice people at Transfusion News sent their update today. Again tranexamic acid appears. And the article on alloimmunization was thought-provoking. Why do some people create antibodies after a single transfusion and others have (literally) gallons and create none?

 

Long-term Survival of Severe Trauma Patients Treated with Tranexamic Acid

June 21, 2023 Globally, trauma is the leading cause of death for young people. In 2011, the World Health Organization added tranexamic acid to the Model List of Essential Medicines for the treatment of trauma based on randomized trial data showing that tranexamic acid reduces mortality of hemorrhaging trauma patients.

Register for the new Transfusion Science Webinar to learn about Phenotype/Genotype Discrepancies, Their Cause, Importance, and Safe Resolution

Hemagglutination methods have been used over a century to determine blood group phenotypes. Serology cannot be used in some situations, leading laboratories to use molecular assays to predict red blood cell (RBC) phenotypes. Sometimes the predicted phenotype does not fit with the patient’s known antibodies or serological phenotype. These phenotype/genotype discrepancies can lead to confusion for laboratory and clinical staff. This can cause anxiety, delays in patient care, or even incorrect conclusions and inappropriate clinical advice and patient care. Shane Grimsley (DipRCPath) will explore some common discrepancies, detailing their causes and how to safely investigate them. This information will provide clues for resolving these issues and ensuring timely and accurate patient care. Join us on June 27th and 30th by registering for this webinar.

Intracellular RBC Antigens Can Enhance RBC Alloimmunization in Mice

June 14, 2023 RBC alloimmunization from transfusions or pregnancy can be life threatening. Currently, scientists have identified 43 polymorphic RBC surface antigen systems, and some are more immunogenic than others. Furthermore, there is a poor understanding of why most patients do not develop alloantibodies and why others respond to one or several antigens. [Read More]

 

25 June 2023 (Sunday) - Transfusion Evidence Alert update

 

The nice people at Transfusion Evidence Alert sent their update today. I can’t pretend to have done more than quickly skimmed it as there was so much, but some of it has stuck. Interestingly the phrase “cost effective” appeared several times…
