OBJECTIVES: Zika virus (ZIKV) transmission through semen donation has never been reported but the risk is supported by the detection of ZIKV in semen and the demonstration of ZIKV sexual transmission. The potential impact of ZIKV on assisted reproductive procedures should be evaluated. METHODS: We tested longitudinally collected semen samples provided by asymptomatic blood donors who tested positive for ZIKV RNA in plasma during ZIKV outbreaks in Puerto Rico and Florida in 2016...

The voluntary and unpaid blood donation is recommended by all international authorities (WHO, Council of Europe, ISBT, EBA), because it represents the best way of aiming towards self-sufficiency in blood products of all kinds, while preserving an optimal level of quality and safety for recipients as for donors. Still infrequent in many developing countries it tends to develop. However, the objective assigned by the WHO to reach 100% of unpaid and voluntary blood donations in 2020 appears ambitious, in particular for the collection of plasma intended to the splitting industry...

BACKGROUND AND OBJECTIVES: Previous work has studied barriers to donating blood or plasma among current, lapsed and non-donors. Still, it remains unclear why donors stop donating and end their donor career voluntarily. A thorough understanding of why donors stop is necessary to develop more effective retention strategies and manage the decline in whole-blood donors. METHODS: An online questionnaire that contained questions about reasons to stop donation was sent out to 7098 Dutch whole-blood donors who deregistered from the donor pool in 2015 but who were not permanently deferred for medical reasons (response: N = 2490, 35%)...

Advances in serology and viral nucleic acid testing (NAT) over the last decades significantly reduced the risk of transfusion-transmitted hepatitis B virus (HBV). The combination of HBsAg testing and NAT efficiently prevents the majority of HBV transmission. However, a specific residual risk remains associated with extremely low viral DNA levels in blood donors with occult HBV infection (OBI) that are intermittently or not detectable even by highly sensitive individual donation (ID) NAT. Studies have reported HBV transfusion-transmission with blood components from donors with OBI that contained low amount of viruses (<200 virions)...

Thrombocytopenia is a common adverse event in cancer patients treated with antibody-drug conjugates (ADCs), including AGS-16C3F, an ADC targeting ENPP3 (ectonucleotide pyrophosphatase/phosphodiesterase-3) and Trastuzumab emtansine (T-DM1). This study aims to elucidate the mechanism of action of ADC-induced thrombocytopenia. ENPP3 expression in platelets and megakaryocytes (MKs) was investigated and shown to be negative. The direct effect of AGS-16C3F on platelets was evaluated using platelet rich plasma following the expression of platelet activation markers...

Hypocalcemic toxicity, because of return of citrate anion to the donor, is the major toxicity of apheresis platelet donation. Oral calcium carbonate, given prophylactically at the start of donation, has shown limited ability to alleviate this toxicity. We examined whether repeated prophylactic doses of calcium carbonate, or of a liquid preparation containing calcium citrate, calcium phosphate, and vitamin D3 , would be more effective at preventing symptoms of hypocalcemic toxicity. Symptoms were reported by 48% of donors who received no prophylaxis and 60% of donors who received 1000 mg of oral calcium carbonate at the start of, and every 20 minutes during, donation (P = 0...

The major contribution of Human Sciences in the understanding of the whole blood donation behavior has been through the study of individuals' motivations and deterrents to donate. However, if whole blood donation has been very widely studied in the last sixty years, we still know very little about plasma donation in voluntary non-remunerated environments. Yet, the need for plasma-derived products has been strongly increasing for some years, and blood collection agencies have to adapt if they want to meet this demand...

BACKGROUND: In August 2016, the Food and Drug Administration advised US blood centers to screen all whole blood and apheresis donations for Zika virus (ZIKV) with an individual-donor nucleic acid test (ID-NAT) or to use approved pathogen reduction technology (PRT). The cost of implementing this guidance nationally has not been assessed. STUDY DESIGN AND METHODS: Scenarios were constructed to characterize approaches to ZIKV screening, including universal ID-NAT, risk-based seasonal allowance of minipool (MP) NAT by state, and universal MP-NAT...

BACKGROUND: Since 1996, ABO-incompatible heart transplantation has been undertaken by performing whole-body plasma exchange to remove isohemagglutinins using the cardiopulmonary bypass (CPB) circuit at the time of transplantation. This requires large volumes of donated blood and blood products, causes hemodynamic instability during the exchange transfusion, and limits practical use to small children. We sought to determine the efficacy of anti-A/B immunoadsorption within the CPB circuit on removal of isohemagglutinins in an ex vivo setting before its use clinically...

BACKGROUND: Repeated blood donation alters the iron balance of blood donors. We quantified these effects by analyzing changes in body iron as well as calculating iron absorbed per day for donors enrolled in a prospective study. STUDY DESIGN AND METHODS: For 1308 donors who completed a final study visit, we calculated total body iron at the enrollment and final visits and the change in total body iron over the course of the study. Taking into account iron lost from blood donations during the study and obligate losses, we also calculated the average amount of iron absorbed per day...

BACKGROUND: Previous studies have shown that Zika virus can infect and be transmitted by A. albopictus. The World Health organization (WHO) has raised concerns of autochthonous transmission of the virus in regions where the vector is endemic. The aim of this pilot study was to assess the occurrence of Zika virus (ZIKV) in western Austria (Tyrol) especially after a history of travel to A. albopictus endemic regions. METHODS: The study participants were healthy blood donors at randomly selected donation sites in the west Austrian region Tyrol...

Many industrial catalysts are composed of metal particles supported on metal oxides (MMO). It is known that the catalytic activity of MMO materials is governed by metal and metal oxide interactions (MMOI), but how to optimize MMO systems via manipulation of MMOI remains unclear, due primarily to the ambiguous nature of MMOI. Herein, we develop a Pt/NbOx/C system with tunable structural and electronic properties via a modified arc plasma deposition method. We unravel the nature of MMOI by characterizing this system under reactive conditions utilizing combined electrochemical, microscopy, and in situ spectroscopy...

The not-for-profit issue has been debated in November 2016 in Paris; this issue is one of the four canonical pillars of ethical blood donation. It is intimately bound to benevolence though it is distinct, as not-for-profit calls for institutions while benevolence calls for individuals. It is indeed intended that voluntary blood donors do not benefit from their donation and are thus non-remunerated. Not-for-profit is essential since it refers to the public character of blood as a putative public resource aimed at being shared as a tribute of solidarity...

Blood doping in sports is prohibited by the World Anti-Doping Agency (WADA). To find a possible biomarker for the detection of blood doping, we investigated the changes in blood stored in CPDA-1 blood bags of eight healthy subjects who donated one unit of blood. Aliquots were taken on days 0, 14 and 35. Platelet free Plasma was prepared and stored at -80 °C until analysis on a flow cytometer dedicated for the analysis of Microparticles (MPs). Changes in the number of Red Blood Cell (RBC) -MPs were highly significant (p < 0...

Non-transferrin-bound iron (NTBI) and free hemoglobin (Hb) accumulate in circulation following stored RBC transfusions. This study investigated transfusion, vascular disease, and mortality in guinea pigs after stored RBC transfusion alone and following cotransfusion with apo-transferrin (apo-Tf) and haptoglobin (Hp). The effects of RBC exchange transfusion dose (1, 3, and 9 units), storage period (14 days), and mortality were evaluated in guinea pigs with a vascular disease phenotype. Seven-day mortality and the interaction between iron and Hb as cocontributors to adverse outcome were studied...
