Administration of Fibrinogen Concentrate during Cardiac Surgery Does Not Significantly Reduce Blood Loss

March 1, 2017
Since fibrinogen plays a key role in hemostasis and it is rapidly depleted during cardiac surgery, many cardiac surgeons give fibrinogen to control bleeding during surgery for high-risk patients. The efficacy of this treatment, however, had not been previously confirmed in large, randomized clinical trials. A recent study in the Netherlands randomized 120 high-risk cardiac [Read More]


Patients with Hematologic Cancers Have Lower Rates of Alloimmunization with RhD

February 22, 2017
Over 20% of RhD-negative non-oncology patients exposed to RhD-positive red blood cells (RBCs) become alloimmunized to the RhD antigen. In oncology patients, however, the rate of alloimmunization is much lower because cancer patients are often immunosuppressed. Since the availability of RhD-negative RBCs is limited, researchers retrospectively investigated 4295 transfusions of RhD-positive RBCs that occurred in [Read More]


Zika-Positive Blood Donations Can Be Inactivated Using Pathogen Inactivation Technologies

February 15, 2017
Emerging infections, such as the Zika virus (ZIKV), continue to surface due to global travel, migration, and the spread of vectors including mosquitoes. The first ZIKV outbreak occurred in 2007 in the Pacific and has quickly spread to most of the Americas. Blood donations have tested positive [Read More]

5 March 2017 (Sunday) - Flow Cytometry



I found this flow cytometry guide which aims to give a basic overview of all the important facets of flow cytometry without delving too deeply into the complex mathematics and physics behind it all.
Instead, it presents a guide that will be invaluable to beginners in flow cytometry and acts as a fact-packed synopsis for those of you interested in teaching others about the virtues of this powerful application.

I no longer do flow cytometry, or teach others. But you never know. I might do again one day…


5 March 2017 (Sunday) - Poor Staining

This post appeared on one of the Facebook groups I follow “A male, 48 yo, with mass in regio colli, Hb 6.5 g/dL, WBC 148,000/uL, Plt 56,000/uL. The blood film is below... What is the diagnosis?”

Various replies were given; some felt AML, some felt mantle cell lymphonas, some thought it was some obscure form of anaemia and some didn’t have the faintest idea.
The correct reply was prolymphocytic leukaemia. Personally I would have given the diagnosis of “awful staining, do it again”.
I wonder if the poor staining was to blame for the range of diagnoses offered. I hope so…


4 march 2017 (Saturday) - A Podcast

The lablogatory people sent an update today.
The legal considerations when providing pathology and laboratory services can be daunting. Whilst at first glance they might seem irrelevant, this podcast gives food for thought.
I like podcasts; I can listen to them anytime. I don’t have to sit and stare at the screen; they can play in the background. I need to find more podcast-based CPD.
