Improvements in donor screening and testing and viral inactivation of plasma derivatives together have resulted in substantial declines in transfusion-transmitted infections over the last two decades. Most recently, nucleic acid testing techniques have been developed to screen blood and plasma donations for evidence of very recent viral infections that could be missed by conventional serologic ...

Background: The aim of this study was to present the basic aspects activity Polish transfusion blood service (hereinafter referred as Centers) in 2021, taking into account conditions related ongoing COVID-19 pandemic. Materials and methods: Analysis data forwarded Institute by Blood Transfusion Centers (Centers). Results: In there were 23 136 local collection sites opeerating Poland. components...

Results The HIV seroprevalence was estimated to be 1.37/1000 donations with 3 generation and 3.62/1000 donations with 4 generation ELISA (p>0.05). Of the 17 samples which were 4 generation ELISA positive and WB positive, 11 were positive with 3 generation ELISA. Fourth generation ELISA tested 19 additional samples positive and 7 samples as possibly positive which were tested negative with 3 gen...

BACKGROUND Reports on unexpected events (UEs) during blood donation (BD) inadequately consider the role of technical UEs. METHODS Defined local and systemic UEs were graded by severity; technical UEs were not graded. On January 1, 2008, E.B.P.S.-Logistics (EBPS) installed the UE module for plasma management software (PMS). Donor room physicians entered UEs daily into PMS. Medical directors re...

Background: Coronary artery bypass surgery is one of the surgeries in which high blood transfusions are needed. About 20% of all surgical operations require a blood transfusion. Packed cell administration increases perioperative morbidity and mortality. In the United States, from every 1000 people, one has undergone a coronary artery bypass graft surgery, and it is estimated that around 800,000...

The aim of this study was to determine the incidence rates of HIV1/2 antibodies, HBV and HCV antibodies among voluntary blood donors and to estimate the residual risk of HIV, HBV and HCV infection among blood donors in Bukavu. We conducted a follow-up cohort study of volunteer blood donors who have made at least two blood donations in Bukavu (DRC) between January 2010 and December 2012. We reco...

BACKGROUND This study examines the impact of an integrated, automated phone system to reinforce retention and increase frequency of donations among blood donors. STUDY DESIGN AND METHODS Cultivated by incorporating data results over the past 7 years, the system uses computerized phone messaging to contact blood donors with individualized, multilevel notifications. Donors are contacted at plan...

Limited red blood cell (RBC) regeneration often prevents collection of sufficient blood from autologous donors. We studied the effects of subcutaneous recombinant erythropoietin (rEPO) in subjects making frequent blood donations. Six healthy iron-replete male subjects took rEPO (200 U/kg) subcutaneously daily, and donated blood (450 mL) twice a week for 3 weeks. During a control study, these su...

HIV was present in 1.1% of transfused blood during the early 1980s in some communities [1]. Perceived shortcomings in the response of the blood community, regulators, and public health authorities led to an exceptionally precautionary approach to transfusion-transmitted infections [2]. In return for unprecedented protection of transfusion recipients, blood donors have since been subjected to be...
