Origin of the Ukrainian minority of Kazakhstan as inferred from HLA-A, -B, -C, -DRB1, and -DQB1 alleles and haplotypes distribution.

HLA 2021 Jul 22. Epub 2021 Jul 22.

Department of Biomedical Sciences, School of Medicine, NazarbayevUniversity, Astana, Kazakhstan.

The present-day population of Kazakhstan comprises more than a hundred ethnic and linguistic groups, of which Ukrainians rates numerically as the fourth, following native Kazakhs, Russians, and Uzbeks. We investigated the HLA profile of Kazakhstani Ukrainians and compared them with those of other populations by applying genetic distances, correspondence analysis, admixture, and haplotype examination. Of the 128 HLA alleles identified, A*02:01 (28. Read More

Controlling Coagulation in Blood with Red Light.

Angew Chem Int Ed Engl 2021 Jul 22. Epub 2021 Jul 22.

University of Frankfurt, Cluster of Excellence Macromolecular Complexes, Max-von-Laue-Str. 9, 60438, Frankfurt, GERMANY.

Precise control of blood clotting and rapid reversal of anticoagulation are essential in many clinical situations. We were successful in modifying a thrombin-binding aptamer with a red-light photocleavable linker derived from Cy7 by Cu-catalysed Click chemistry. We were able to show that we can successfully deactivate the modified aptamer with red light (660 nm) even in human blood - restoring the blood's natural coagulation capability. Read More

Platelet EVs contain an active proteasome involved in protein processing for antigen presentation via MHC-I molecules.

Blood 2021 Jul 22. Epub 2021 Jul 22.

CHU de Quebec, Quebec, Quebec, Canada.

In addition to their hemostatic role, platelets play a significant role in immunity. Once activated, platelets release extracellular vesicles (EVs) formed by budding of their cytoplasmic membranes. Because of their heterogeneity, platelet EVs (PEVs) are thought to perform diverse functions. Read More

Donor orientation and service quality: Key factors in active blood donors' satisfaction and loyalty.

PLoS One 2021 22;16(7):e0255112. Epub 2021 Jul 22.

Department of Business Economics, Faculty of Legal and Business Sciences, Universidad Rey Juan Carlos, Madrid, Spain.

Faced with the increasing demand for blood and greater restrictions on ensuring the safety of transfusions, voluntary donation is currently the only and best alternative for the health system to have a sustainable and safe blood supply. In this context, one of the primary strategies of blood transfusion centres is to increase the satisfaction of their active donors so that they maintain their intention to donate in the future and, in turn, make the necessary recommendations so that third parties can become new donors. That is why this paper raises a question for research concerning, what should the premises be to guide the management of blood transfusion centres to maintain and even increase the satisfaction and loyalty of their active donors? In order to respond to this issue, a change in paradigm is proposed based on a management model supported by donor orientation and service quality as basic pillars, as well as on the development of a number of key social capital resources that explain this orientation toward the donor.

Strong association between insufficient plasma exchange and fatal outcomes in Japanese patients with immune-mediated thrombotic thrombocytopenic purpura.

Int J Hematol 2021 Jul 22. Epub 2021 Jul 22.

Department of Blood Transfusion Medicine, Nara Medical University, 840 Shijo-Cho, Kashihara, 634-8522, Japan.

Plasma exchange (PEX) using fresh frozen plasma has considerably reduced the mortality rate in patients with immune-mediated thrombotic thrombocytopenic purpura (iTTP). However, some patients still do not survive even with treatment, but little information is available regarding which treatment these patients received. This study was conducted to obtain this information in 240 patients who met the current iTTP diagnostic criteria and completed at least 30 days of follow-up except for deceased cases. Read More

Novel Scalable and Simplified System to Generate Microglia-Containing Cerebral Organoids From Human Induced Pluripotent Stem Cells.

Front Cell Neurosci 2021 5;15:682272. Epub 2021 Jul 5.

Department of Pathology and Laboratory Medicine, Temple University Lewis Katz School of Medicine, Philadelphia, PA, United States.

Human cerebral organoid (CO) is a three-dimensional (3D) cell culture system that recapitulates the developing human brain. While CO has proved an invaluable tool for studying neurological disorders in a more clinically relevant matter, there have still been several shortcomings including CO variability and reproducibility as well as lack of or underrepresentation of certain cell types typically found in the brain. As the technology to generate COs has continued to improve, more efficient and streamlined protocols have addressed some of these issues. Read More

How do I think about blood donor eligibility criteria for medical conditions?

Authors:
Mindy Goldman

Transfusion 2021 Jul 21. Epub 2021 Jul 21.

Medical Affairs and Innovation, Canadian Blood Services, Ottawa, Ontario, Canada.

Every blood center must determine blood donor eligibility criteria for donors with medical conditions, often based on very limited published data and variable practice. This manuscript briefly outlines possible impacts of donor medical conditions on donor and recipient safety and product quality, and describes the multidisciplinary approach used in Canada to think about donor criteria issues. Many years of experience are distilled into practical considerations in determining criteria, possible sources of information, and factors for successful change implementation, to hopefully assist medical and technical staff engaged in decision-making around donor eligibility.

Transfusion 2021 Jul 21. Epub 2021 Jul 21.

Medical Affairs, Novavax Inc, Gaithersburg, Maryland, USA.

Background: Large volume delayed sampling (LVDS) and pathogen reduction technology (PRT) are strategies for platelet processing to minimize transfusion of contaminated platelet components (PCs). This study holistically compares the economic and clinical impact of LVDS and PRT in the United States.

Study Design And Methods: A decision model was constructed to simulate collection, processing, and use of PCs and to compare processing strategies: PRT with 5-day shelf life, LVDS with 7-day shelf life (LVDS7), and LVDS with 5-day shelf life extended to 7 days with secondary testing (LVDS5/2).
