Abstract
Erythropoiesis-stimulating agents (ESAs) are man-made forms of erythropoietin used in the treatment of anemia. This quick-scoping review of systematic literature reviews (SLRs) was conducted to define the clinical, economic, and health-related quality of life (HRQoL) outcomes for short-acting and long-acting ESAs in patients with chronic kidney disease-induced anemia (CKD-IA) and patients with chemotherapy-induced anemia (CIA). Embase, Medline, and the Cochrane Database of Systematic Reviews were searched from their establishment until October 2017. SLRs related to the use of short-acting and long-acting ESAs in the treatment of CIA and CKD-IA were included. Forty-eight studies met the inclusion criteria. The evidence suggests little difference in efficacy, HRQoL, and safety outcomes among ESA types. Cost-effectiveness and market price are likely to become determining factors driving the choice of agent. Comparative studies and costing models accounting for the utilization of biosimilars are needed to establish which ESAs are more cost-effective.Copyright © 2018. Published by Elsevier B.V.

Abstract
Importance: Pathogen reduction of platelet concentrates may reduce transfusion-transmitted infections but is associated with qualitative impairment, which could have clinical significance with regard to platelet hemostatic capacity. Objective: To compare the effectiveness of platelets in additive solution treated with amotosalen-UV-A vs untreated platelets in plasma or in additive solution in patients with thrombocytopenia and hematologic malignancies. Design, Setting, and Participants: The Evaluation of the Efficacy of Platelets Treated With Pathogen Reduction Process (EFFIPAP) study was a randomized, noninferiority, 3-arm clinical trial performed from May 16, 2013, through January 21, 2016, at 13 French tertiary university hospitals. Clinical signs of bleeding were assessed daily until the end of aplasia, transfer to another department, need for a specific platelet product, or 30 days after enrollment. Consecutive adult patients with bone marrow aplasia, expected hospital stay of more than 10 days, and expected need of platelet transfusions were included. Interventions: At least 1 transfusion of platelets in additive solution with amotosalen-UV-A treatment, in plasma, or in additive solution. Main Outcomes and Measures: The proportion of patients with grade 2 or higher bleeding as defined by World Health Organization criteria. Results: Among 790 evaluable patients (mean [SD] age, 55 [13.4] years; 458 men [58.0%]), the primary end point was observed in 126 receiving pathogen-reduced platelets in additive solution (47.9%; 95% CI, 41.9%-54.0%), 114 receiving platelets in plasma (43.5%; 95% CI, 37.5%-49.5%), and 120 receiving platelets in additive solution (45.3%; 95% CI, 39.3%-51.3%). With a per-protocol population with a prespecified margin of 12.5%, noninferiority was not achieved when pathogen-reduced platelets in additive solution were compared with platelets in plasma (4.4%; 95% CI, -4.1% to 12.9%) but was achieved when the pathogen-reduced platelets were compared with platelets in additive solution (2.6%; 95% CI, -5.9% to 11.1%). The proportion of patients with grade 3 or 4 bleeding was not different among treatment arms. Conclusions and Relevance: Although the hemostatic efficacy of pathogen-reduced platelets in thrombopenic patients with hematologic malignancies was noninferior to platelets in additive solution, such noninferiority was not achieved when comparing pathogen-reduced platelets with platelets in plasma.

Abstract
BACKGROUND The prevention of presyncopal and syncopal reactions to whole blood donation is important for both the donor's safety and their retention as blood donors. The best strategy to achieve this remains debated. STUDY DESIGN AND METHODS A prospective cluster-randomized trial comparing three hydration modes (500 mL of an isotonic drink, 500 mL of water, just before phlebotomy, or advice to drink [control arm]) coupled or not with light muscle tensing exercises, was carried out in mobile and fixed units of two regional blood centers in southeast France between January and July 2014. The main outcome was the cumulative incidence of presyncope (feeling faint) and syncope (fainting) at the donation site or in the 48 hours after leaving the site. Secondary outcomes were the cumulative incidence of these adverse events during donation, immediately after blood donation, or within 48 hours. RESULTS Overall, presyncope or syncope occurred in 5.5% of the 4576 donors. Compared to controls, drinking 500 mL (isotonic solution or water) significantly reduced the rate of events (odds ratio [OR], 0.74; 95% confidence interval [CI], 0.55-0.99; p = 0.041) independently of muscle tensing exercise. Muscle tensing exercises significantly reduced syncopal-type reactions during the donation (OR, 0.64; 95% CI, 0.42-0.98; p = 0.041), and an isotonic drink significantly reduced delayed off-site syncopal-type reactions (OR, 0.62; 95% CI, 0.40-0.98; p = 0.040) and tiredness after donation (OR, 0.75; 95% CI, 0.59-0.94; p = 0.014). CONCLUSIONS Drinking 500mL of water or isotonic drink close to phlebotomy is useful in preventing presyncopal or syncopal reactions in blood donors. Isotonic drinks have the advantage of preventing delayed reactions and tiredness after whole blood donation.
