Monitoring trends in residual risk of transfusion-transmitted viral infections is important to assess improvements in blood safety and to adapt the risk reduction policies. These trends were analysed in France over 4 periods of 3 years (1992-1994, 1995-1997, 1998-2000 and 2001-2003). The 2001-2003 estimates were compared to the results of HIV-1 and HCV NAT implemented on all blood donations in ...

BACKGROUND Chronic blood shortages in the U.S. would be alleviated by small increases, in percentage terms, of people donating blood. The current research investigated the effects of subtle changes in charity-seeking messages on the likelihood of people responses to a call for help. We predicted that "avoid losses" messages would lead to more helping behavior than "promote gains" messages would...

In this issue of Blood, Hjalgrim et al used the Scandinavian Donations and Transfusions (SCANDAT2) database, which includes comprehensive information on donors and recipients of >20 million blood products handled by the Danish and Swedish blood banks between 1968 and 2010, to address the clinically relevant question of whether chronic lymphocytic leukemia (CLL) is transmitted through blood tran...

BACKGROUND The prevalence of chronic Hepatitis B Virus (HBV) infection is 2-4% in the Pakistani population, defining Pakistan as an intermediate prevalence country. In this study, hepatitis B surface antigen (HBsAg) reactive blood donations were screened using a combination of serological and molecular methods to identify immune escape HBV mutant strains and to determine the HBV genotypes and s...

Blood donation is someone who voluntarily gives blood; then, the feasibility processed and transfused to patients in need. donors come from voluntary blood or substitute donors/families certain communities. The COVID-19 pandemic spread of a coronavirus epidemic that has various continents countries. This research quantitative descriptive study with time approach used as retrospective. number do...

BACKGROUND Transfusion-associated malaria is a potentially serious complication that continues to pose risks in blood bank settings. There is a need for effective malaria screening of blood donations to improve on the current exclusion policies of potentially infected carriers on the basis of clinical and travel history. We evaluated the potential usefulness of ELISA screening for malaria antib...

Umbilical cord blood (UCB) contains hematopoietic stem cells and multipotent mesenchymal cells useful for treatment in malignant/nonmalignant hematologic-immunologic diseases and regenerative medicine. Transplantation outcome is correlated with cord blood volume (CBV), number of total nucleated cells (TNC), CD34+ progenitor cells and colony forming units in UCB donations. Several studies have a...

BACKGROUND Hepatitis E virus genotype-3 (HEV-gt-3) causes autochthonous infections in western countries, with a primary reservoir in animals, especially pigs. HEV transfusion transmission has been reported, and HEV-gt-3 prevalence is high in some European countries. The prevalence of HEV RNA was investigated among Danish blood donors, and the prevalence of HEV transfusion-transmitted infection ...

background: lead toxicity has been reported to affect hematopoietic, nervous, reproductive, cardiovascular and urinary tract systems. many investigators have so far studied the effects of high blood lead levels on pregnancy outcomes. objective: to investigate the effects of elevated maternal blood lead during pregnancy on some trace elements and pregnancy outcomes. methods: blood lead and plasm...
