The purpose of this study, based on the Theory of planned behavior, is to identify and ultimately better understand what determines the fidelity and the regularity of donors committed in plasmapheresis donation. This qualitative study is a primary stage to establish a classification of donors in a French socio-cultural context. For this reason, we have carried out a survey among 16 regular plasmapheresis donors, by way of semi-structured individual interviews at the Établissement français du sang - Brittany...

BACKGROUND: Various strategies are implemented to increase blood safety. However, there is always a small amount of residual risk. The amount of risk is associated with the incidence and prevalence of infection in the community. Since increases in the prevalence and changing the pattern of HIV transmission have been observed in the community, monitoring of HIV prevalence among general population and blood donors is necessary. This study aimed to determine the prevalence of HIV in Iranian blood donations...

BACKGROUND: Variant Creutzfeldt-Jakob disease (vCJD) has been transmitted by blood transfusion (TTvCJD). The US Food and Drug Administration (FDA) recommends deferring blood donors who resided in or traveled to 30 European countries where they may have been exposed to bovine spongiform encephalopathy (BSE) through beef consumption. Those recommendations warrant re-evaluation, because new cases of BSE and vCJD have markedly abated. STUDY DESIGN AND METHODS: The FDA developed a risk-ranking model to calculate the geographic vCJD risk using country-specific case rates and person-years of exposure of US blood donors...

BACKGROUND: The availability of safe blood and blood products is a critical factor in improving health care. In Ethiopia, lack of voluntary blood donors is a major challenge. This could be due to low community knowledge, unfavorable attitude, and poor donation practice regarding voluntary blood donation. Thus, the aim of this study was to assess community knowledge, attitude, and practice regarding voluntary blood donation among adults in Harar town, Ethiopia. MATERIALS AND METHODS: A community-based cross-sectional study was conducted from July 1 to July 31, 2015...

Apheretic platelets are better quality blood components which reduce donor exposure and chances of TTIs to transfusion recipients when compared to the whole blood derived components. Though safe, these apheretic donations are associated with donor adverse events. We evaluated the incidence of such adverse events associated with the modern apheresis procedures that would provide an insight as well as help formulating preventive steps to avoid frequent occurrences of such events. This prospective audit-based observational study was conducted over 1 year...

BACKGROUND: Human T-cell lymphotrophic virus type 1 (HTLV-1) has a worldwide distribution and it is endemic in some regions of Iran. One of the most important routes of HTLV-1 transmission is via transfusion of contaminated blood components. The risk of transmission through asymptomatic blood donors, particularly in endemic areas should be considered and appropriately managed. The main objective of this study was to determine the seroprevalence and description the geographic distribution of HTLV-1 among voluntary blood donors in Iran...

BACKGROUND: Umbilical cord blood (UCB) is an important source of hematopoietic stem cells for transplantation especially in minority populations with limited chances of finding a histocompatible volunteer donor in the registry. UCB has the advantages of early availability, successful outcomes despite some histocompatibility mismatch, and low incidence of chronic graft-versus-host disease. Public cord blood banks that disseminate UCB products for transplant depend on voluntary donation at participating hospitals and obstetrical providers for collection...

Although considerable progress has been made in improving the blood service system in China over the last 2 decades, many challenges remain. A number of issues have received public attentions; however, others continue to be underacknowledged and controversial. This article describes 3 of these important and less emphasized issues: first, the ambiguity of the definition of voluntary nonremunerated blood donation and its relationship to an adequate blood supply; second, the current inadequacies of cost recovery from the blood service system; and third, the lack of a universally implemented program of hemovigilance...

BACKGROUND: Predonation hemoglobin (Hb) for plateletpheresis donors is estimated by presently available invasive methods. Venous samples of only those donors whose Hb is more than 12.5 g/dl are screened for complete blood count and transfusion transmissible infections. There is a pressing need to substitute this invasive Hb test with noninvasive one to reduce donor discomfort and avoid further pricking the donor. We therefore went ahead with the aim of comparing a noninvasive Hb estimation method NBM 200 with the invasive method - Hemocue, taking SYSMEX KX-21 as a gold standard...
