BACKGROUND & AIMS: There is a considerable burden of hepatitis C in Europe related to the lack of prompt diagnosis. We aimed to estimate the prevalence and related risk factors of HCV infections by the stages of liver fibrosis, using non-invasive methods, to understand testing needs in Poland. METHODS: A cross-sectional study was conducted in 2012-2016 adopting a stratified random sampling of primary health care units followed by systematic sampling of patients within each unit...

Perfluorochemicals (PFCs) constitute one class of artificial oxygen carriers that are being produced completely synthetically. One formulation that has been evaluated extensively in clinical trials is a 60% w/v perflubron-based emulsion. Efficacy and safety of this perflubron emulsion was evaluated in a Phase 2 and a large prospective randomized Phase 3 multicenter European study, which collectively included a total of 639 patients. Perflubron emulsion was highly successful in improving organ function, reversing physiologic transfusion triggers and in reducing the need for allogeneic blood transfusions...

REVIEW
Karen Ballen
Allogeneic hematopoietic cell transplant is a curative procedure for many patients with leukemia, lymphoma, myelodysplasia, myeloproliferative neoplasms, and genetic disorders. Umbilical cord blood transplantation is a graft source for patients who do not have a matched donor in their family or in the unrelated registry. It is particularly difficult for Black, Hispanic, and White patients of non-Western European background to find fully matched adult volunteer donors. An estimated 700,000 umbilical cord blood units have been donated for public use, and over 40,000 umbilical cord blood transplantations have been performed...

DNA and RNA samples from blood are the common examination target for non-invasive physical tests and/or biomedical studies. Since high-quality DNA and RNA samples guarantee the correctness of these tests and/or studies, we investigated the effects of storage temperature and storage duration of whole blood on DNA and RNA qualities. Subjects were enrolled to donate blood samples which were stored for different durations and at different temperatures, followed by the examinations on RNA quality, qPCR, DNA quality and DNA methylation...

REVIEW
Ruth Offergeld, Margarethe Heiden
The selection of blood donors includes the assessment of the individual's health and medical history by using a donor questionnaire (DQ) in order to identify persons whose donation could present a health risk to recipients or to themselves. This way, DQs provide one layer of blood safety and contribute to the high safety profile of blood components currently available in Germany. This review reports the development of a new uniform questionnaire in Germany and its first evaluation using a field test approach...

BACKGROUND: We assessed the effect of the uniform donor questionnaire (UDQ) on deferral rates in first-time and repeat donors. We focused on the introduced question about unprotected sexual contact with a new partner. Another goal was a stratified comparison of the deferral rates of the donor questionnaire (DQ) and UDQ. METHODS: Data on donors and deferrals using the DQ and UDQ were collected at four blood establishments. The comparison included a 2-year period by questionnaire version...

BACKGROUND: Securing future blood supply is a major issue of transfusion safety. In this prospective 10-year longitudinal study we enrolled all blood donation services and hospitals of the federal state Mecklenburg-Western Pomerania. METHODS AND RESULTS: From 2005 to 2015 (time period with major demographic effects), whole blood donation numbers declined by 18%. In male donors this paralleled the demographic change, while donation rates of females declined 12.4% more than expected from demography...

BACKGROUND: In the recent past, the discrepancy between blood supply and future demand may have been overestimated. As medical progress develops rapidly, it will be essential to monitor ongoing demographic changes in the donor population regularly and to re-evaluate retention and recruiting strategies. The aim of the current study was to compare first-time donor (FTD) characteristics and their return rates. We therefore compared whole blood (WB) donations in total and the annual donation frequencies in 2010 and in 2015/2016...

INTRODUCTION: Isolated microscopic hematuria (IMH) is not uncommon in potential kidney donors. AIM: The aim was to study the kidney biopsy findings of potential kidney donors with IMH and the impact of the histopathologic diagnoses on the decision to accept or decline such donors from kidney donation. METHODS: In this retrospective study, all the potential kidney donors with IMH were identified from the medical records of patients who underwent kidney biopsies between January 2010 and December 2016...

BACKGROUND: In 2015, there was a large Zika virus (ZIKV) outbreak in Brazil. The proportion of asymptomatic infections is very high, and it is possible for transfusion-transmitted ZIKV (TT-ZIKV) infection to occur. The prevalence of asymptomatic ZIKV infection among Brazilian blood donors during this epidemic outbreak is unknown. STUDY DESIGN AND METHODS: Plasma samples obtained between October 2015 and May 2016 from 1393 volunteer blood donors were tested for ZIKV RNA...

Five studies examined defensive intergroup helping-when responsibility for an out-group victim's injury decreases helping, whereas lack of responsibility increases helping when death is salient. In Study 1 ( N = 350), implicit death primes increased petition signings to allow a Palestinian child to receive medical treatment in Israel, when the child was a victim of Palestinian fire. When the child was a victim of Israeli fire, however, death primes decreased petition signings. Study 2 ( N = 200) partially replicated these effects on commitment to donate blood to an injured Palestinian child...

The number of hospitalized patients receiving treatment perceived to be futile is not insignificant. Blood products are valuable resources that are donated to help others in need. We aimed to quantify the amount of blood transfused into patients who were receiving treatment that the critical care physician treating them perceived to be futile. During a 3-month period, critical care physicians in 5 adult intensive care units completed a daily questionnaire to identify patients perceived as receiving futile treatment...

Hereditary hemochromatosis (HH) is a genetic disorder of iron metabolism which may lead to iron overload. Clinical penetrance is low, however those afflicted may develop cirrhosis, hepatocellular carcinoma, diabetes mellitus and cardiomyopathy. Treatment involves regular phlebotomy to reduce the systemic iron burden. In many countries-including the United States-numerous blood centers do not accept donated blood obtained from HH patients during therapeutic phlebotomy and there are inconsistent positions regarding this globally...

Protein surface patterning is employed in a broad spectrum of applications ranging from protein micro-array analysis to 2D cell organization. However, limitations arise due to the highly sensitive nature of proteins requiring careful handling to ensure their structural and functional integrity during the grafting process. Here we describe a patterning protocol that keeps proteins in an aqueous environment during their immobilization, avoiding loss of their biological activity. The procedure is based on the UV-mediated removal of Poly-Ethylene Glycol (PEG) Self-Assembled Monolayers (SAMs) in a transparent microfluidic chamber, giving access to micrometric motifs of predefined geometries...

BACKGROUND AND OBJECTIVES: The Korean Red Cross began nucleic acid amplification testing (NAT) for HIV and HCV in February 2005, and added HBV NAT beginning in June 2012. The current NAT system utilizes a multiplex assay for simultaneous detection of HBV DNA, HCV RNA and HIV-1 RNA. For samples that are reactive in the multiplex assay, we do specific tests for each virus. However, there have been cases of non-discriminated reactive (NDR) results which appear to be the result of non-specific reactions or cross-contamination, although some cases are considered to arise from the presence of low levels of HBV DNA due to occult hepatitis B infection...

BACKGROUND: Chronic kidney disease is characterized by stiffening, thinning, dilatation, and increased circumferential wall stress of large arteries, associated with increased cardiovascular risk. Kidney transplantation (KT) reverses many pathological features of chronic kidney disease and improves life expectancy; however, longitudinal studies exploring the impact of KT on recipient large arteries are scarce. METHODS AND RESULTS: This study was designed to appraise arterial changes following KT...

BACKGROUND: Directed donation is associated with a higher prevalence of donations that are positive for infectious disease markers; however, little is known about the positive rates among parental-directed, non-parental-directed, and allogeneic donations. STUDY DESIGN AND METHODS: We reviewed blood-collection records from January 1997 through December 2008, including infectious disease results, among parental, non-parental, and community donations. Infectious disease rates were compared by Mann-Whitney U test...

INTRODUCTION: Military elements increasingly operate in small teams in remote areas with no immediate blood product support. Planners and operators may endorse collection of fresh whole blood from pretested donors in emergency situations. The biggest risk of transfusion is the accidental use of ABO incompatible blood which can be fatal. The risk may be mitigated by using only group O LOw (OLO) titre donors with plasma containing low levels of the naturally occurring antibody to group A and B red cells...
