- The European Hematology Association (EHA) Roadmap for European Hematology Research highlights major achievements in diagnosis and treatment of blood disorders and identifies the greatest unmet clinical and scientific needs in those areas to enable better funded, more focused European hematology research. Initiated by the EHA, around 300 experts contributed to the consensus document, which will help European policy makers, research funders, research organizations, researchers, and patient groups make better informed decisions on hematology research. It also aims to raise public awareness of the burden of blood disorders on European society, which purely in economic terms is estimated at (sic)23 billion per year, a level of cost that is not matched in current European hematology research funding. In recent decades, hematology research has improved our fundamental understanding of the biology of blood disorders, and has improved diagnostics and treatments, sometimes in revolutionary ways. This progress highlights the potential of focused basic research programs such as this EHA Roadmap. The EHA Roadmap identifies nine 'sections' in hematology: normal hematopoiesis, malignant lymphoid and myeloid diseases, anemias and related diseases, platelet disorders, blood coagulation and hemostatic disorders, transfusion medicine, infections in hematology, and hematopoietic stem cell transplantation. These sections span 60 smaller groups of diseases or disorders. The EHA Roadmap identifies priorities and needs across the field of hematology, including those to develop targeted therapies based on genomic profiling and chemical biology, to eradicate minimal residual malignant disease, and to develop cellular immunotherapies, combination treatments, gene therapies, hematopoietic stem cell treatments, and treatments that are better tolerated by elderly patients.

- OBJECTIVES: This study was designed to evaluate biomarkers for selection of patients with non-ST-segment elevation acute coronary syndromes (ACS) that derive mortality benefit from revascularization. BACKGROUND: Biomarkers are essential for identification of patients at increased risk, which may be reduced by revascularization. METHODS: During the initial 30 days, 2,340 patients of 7,800 (30%) with non-ST-segment elevation ACS in the GUSTO (Global Utilization of Strategies To open Occluded arteries)-IV trial underwent coronary revascularization. The 1-year mortality was calculated in 30-day survivors stratified by status of revascularization and levels of biomarkers. A propensity score for receiving revascularization was constructed and included in a survival analysis that also included the time point of revascularization as a time-dependent covariate. RESULTS: Elevation of troponin-T or N-terminal pro-B-type natriuretic peptide (NT-proBNP) was associated with a high mortality. In patients with either or both of these markers elevated, a lower mortality following revascularization was observed. In contrast, patients without elevation of these markers had low 1-year mortality without any reduction in mortality following revascularization. In fact, in patients with normal levels of both troponin-T and NT-proBNP, a significant increase in 1-year mortality after revascularization was observed. Elevation of C-reactive protein, interleukin-6, creatinine clearance, and ST-segment depression was also related to a higher mortality. However, independent of these markers, mortality was lower after revascularization. CONCLUSIONS: Markers of troponin-T and NT-proBNP not only assist in risk stratification of patients with non-ST-segment elevation ACS but also appear to identify patients who have a reduced mortality associated with early coronary revascularization.

- Research question: Elective single-embryo transfer (eSET) at blastocyst stage is widely used to reduce the frequency of multiple pregnancies after IVF. There are, however, concerns about increased risks for the offspring with prolonged embryo culture. Is it possible to select embryos for transfer at the early cleavage stage and still achieve low twin rates at preserved high live birth rates? Design: A prediction model (PM) was developed to optimize eSET based on variables known 2 days after oocyte retrieval (fresh day 2 embryo transfers; double-embryo transfers 1999-2002 (n=2846) and SET 1999-2003 (n=945); n total=3791). Seventy-five variables were analysed for association with pregnancy chance and twin risk and combined for PM construction. This PM was validated in 2004-2016 including frozen-thawed transfers (FET), to compare cumulative live birth rate (CLBR) and twin rate before (1999-2002 fresh embryo transfers plus FET from the same oocyte retrievals until the end of 2007, n=3495) and after (2004-2011 fresh embryo transfers plus FET from the same oocyte retrievals until the end of 2016, n=11195) implementing the model. Results: The PM was constructed from four independent variables: female age, embryo score, ovarian sensitivity and treatment history. The calibration, i.e. the fit of observed versus predicted results, was excellent both at construction and at validation. Without compromising CLBR, twin rate was reduced from 25.2% to 3.8%, accompanied by profound improvements in perinatal outcome. Conclusion: The results provide the first successful construction, validation and impact analysis of a day 2 transfer PM to reduce multiple pregnancies.

- The transferability and clinical value of genetic risk scores (GRSs) across populations remain limited due to an imbalance in genetic studies across ancestrally diverse populations. Here we conducted a multi-ancestry genome-wide association study of 156,319 prostate cancer cases and 788,443 controls of European, African, Asian and Hispanic men, reflecting a 57% increase in the number of non-European cases over previous prostate cancer genome-wide association studies. We identified 187 novel risk variants for prostate cancer, increasing the total number of risk variants to 451. An externally replicated multi-ancestry GRS was associated with risk that ranged from 1.8 (per standard deviation) in African ancestry men to 2.2 in European ancestry men. The GRS was associated with a greater risk of aggressive versus non-aggressive disease in men of African ancestry (P = 0.03). Our study presents novel prostate cancer susceptibility loci and a GRS with effective risk stratification across ancestry groups.
