DOI: 10.5581/1516-8484.20130073 An article in this issue of the Revista Brasileira de Hematologia e Hemoterapia addresses one of the most difficult management challenges in blood banking: balancing supply and demand of blood and blood products collected from volunteer, non-remunerated donors (1). It looks specifically at the distribution of weekly blood collections at three major Brazilian bloo...

INTRODUCTION The study was conducted to assess the knowledge and attitude of college-going students toward voluntary blood donation and to bring out and compare the reasons for donating or not donating blood. MATERIALS AND METHODS This cross-sectional study was conducted on 1,000 college-going students after taking their consent for participation using a prevalidated, self-administered, struc...

Since the provision of blood and blood products depends entirely on the willingness of donors to spend their blood for this purpose, we felt that an International Forum of Vox Sanguinis should be devoted to donor recruitment and in particular to ‘donor loyalty’ and to ‘barriers to blood donation’. To obtain information on these subjects, the following questions were sent to experts in the field...

Allogeneic hematopoietic Stem Cell Transplantation (ASCT) is well established as a curative treatment for many hematological malignancies and non-malignant disorders. The aim of ASCT in these diseases is to achieve sustained donor engraftment to fight leukemic cells in malignant disease, improve hematopoietic function, provide immune competence or normalize enzyme deficiency. Peripheral blood o...

Selection of a suitable graft for allogeneic hematopoietic stem cell transplantation involves consideration of both donor and recipient characteristics. Of primary importance is sufficient donor-recipient HLA matching to ensure engraftment and acceptable rates of GVHD. In this Perspective, the National Marrow Donor Program and the Center for International Blood and Marrow Transplant Research pr...

Background Asymptomatic malaria parasitaemia has been documented in donor blood in West Africa. However, donated blood is not routinely screened for malaria parasites (MPs). The present study therefore aimed to document the frequency of blood transfusion-induced donor-recipient malaria parasitaemia patterns, in children receiving blood transfusion in a tertiary health-centre. Methodology A cr...

the Japanese society in the upcoming years. Ngoma et al. [4] investigate reasons for blood donor deferral among Japanese students in northern Japan. In order to select suitable donors, deferral rates, reasons for deferral, and characteristics of deferred donors are being analyzed. The data suggest that continuous efforts are required to motivate potential donors to return after transient deferr...

stem cells are undifferentiated biological cells that can differentiate into specialized cells and can divide (through mitosis) to produce more stem cells. they are found in multicellular organisms. in mammals, there are two broad types of stem cells: embryonic stem cells, which are isolated from the inner cell mass of blastocysts, and adult stem cells, which are found in various tissues. in ad...

Allogeneic hematopoietic cell transplantation has an established role in the treatment of adults with acute lymphoblastic leukemia whose survival when recipients of grafts from adult unrelated donors approaches that of recipients of grafts from sibling donors. Our aim was to determine the role of mismatched unrelated cord blood grafts in transplantation for 802 adults with acute lymphoblastic l...

The emphasis on high-school blood drives and acceptance of 16-year-old blood donors led to more research on physiologic and psychological ways to decrease vasovagal reaction rates in young blood donors and to increase donor retention. Research on how to accomplish this has been advantageous for the blood collection industry and blood donors. This review discussed the current situation and what ...
