Geographic Mobility in the European Union: Optimising its Economic and Social Benefits
One of the founding principles of the European Union is the freedom of movement of workers (Article 39 of the Treaty establishing the European Community). The free movement of workers is essential for the creation of an area without internal frontiers, and for the strength-ening of economic and social cohesion and active citizenship.Taking an economic perspective, geographic mobility can have major positive effects by bringing about economic growth in countries with labour deficits and prosperity in countries with labour surplus. Hence, the diffusion of skills through occupational and geographic mo-bility is a central factor to enhance the productive capacity of firms and put regions or na-tional economies on a higher growth path. Taking a social perspective, geographical mobility has the potential of fostering social-cultural integration in the European Union, and strength-ening European identity and inter-cultural networks

Graft-versus-Host disease Prophylaxis with Everolimus and Tacrolimus Is Associated with a High Incidence of Sinusoidal Obstruction Syndrome and Microangiopathy: Results of the EVTAC Trial
AbstractA calcineurin inhibitor combined with methotrexate is the standard prophylaxis for graft-versus-host disease (GVHD) after allogeneic hematopoietic stem cell transplantation (HSCT). Everolimus, a derivative of sirolimus, seems to mediate antileukemia effects. We report on a combination of everolimus and tacrolimus in 24 patients (median age, 62 years) with either myelodysplastic syndrome (MDS; n = 17) or acute myeloid leukemia (AML; n = 7) undergoing intensive conditioning followed by HSCT from related (n = 4) or unrelated (n = 20) donors. All patients engrafted, and only 1 patient experienced grade IV mucositis. Nine patients (37%) developed acute grade II-IV GVHD, and 11 of 17 evaluable patients (64%) developed chronic extensive GVHD. Transplantation-associated microangiopathy (TMA) occurred in 7 patients (29%), with 2 cases of acute renal failure. The study was terminated prematurely because an additional 6 patients (25%) developed sinusoidal obstruction syndrome (SOS), which was fatal in 2 cases. With a median follow-up of 26 months, the 2-year overall survival rate was 47%. Although this new combination appears to be effective as a prophylactic regimen for acute GVHD, the incidence of TMA and SOS is considerably higher than seen with other regimens
Vorstudie zur Evaluation von FördermaĂnahmen fĂŒr Jugendliche im SGB II und SGB III: Endbericht
Die Leistungen der arbeitsmarktpolitischen Förderung von jungen Menschen unter 25 Jahren im Bereich der aktiven Arbeitsmarktpolitik wurden bislang nur ausschnittsweise, nicht systematisch und ohne die vorrangige Intention untersucht, einen Ăberblick ĂŒber alle MaĂnahmen sowie deren forschungsrelevante Implikationen zu gewinnen. Deshalb wird im Rahmen dieser Vorstudie der Forschungsstand erfasst und bewertet, um damit etwaige ForschungslĂŒcken und kĂŒnftigen Forschungsbedarf zu identifizieren. Darauf aufbauend wird ein Forschungsdesign fĂŒr eine eventuell folgende ganzheitliche Evaluation vorgestellt
ASIME 2018 White Paper. In-Space Utilisation of Asteroids: Asteroid Composition -- Answers to Questions from the Asteroid Miners
In keeping with the Luxembourg government's initiative to support the future
use of space resources, ASIME 2018 was held in Belval, Luxembourg on April
16-17, 2018.
The goal of ASIME 2018: Asteroid Intersections with Mine Engineering, was to
focus on asteroid composition for advancing the asteroid in-space resource
utilisation domain. What do we know about asteroid composition from
remote-sensing observations? What are the potential caveats in the
interpretation of Earth-based spectral observations? What are the next steps to
improve our knowledge on asteroid composition by means of ground-based and
space-based observations and asteroid rendez-vous and sample return missions?
How can asteroid mining companies use this knowledge?
ASIME 2018 was a two-day workshop of almost 70 scientists and engineers in
the context of the engineering needs of space missions with in-space asteroid
utilisation. The 21 Questions from the asteroid mining companies were sorted
into the four asteroid science themes: 1) Potential Targets, 2)
Asteroid-Meteorite Links, 3) In-Situ Measurements and 4) Laboratory
Measurements. The Answers to those Questions were provided by the scientists
with their conference presentations and collected by A. Graps or edited
directly into an open-access collaborative Google document or inserted by A.
Graps using additional reference materials. During the ASIME 2018, first day
and second day Wrap-Ups, the answers to the questions were discussed further.
New readers to the asteroid mining topic may find the Conversation boxes and
the Mission Design discussions especially interesting.Comment: Outcome from the ASIME 2018: Asteroid Intersections with Mine

Promoting mental health and well-being in schools: examining mindfulness, relaxation and strategies for safety and well-being in English primary and secondary schoolsâstudy protocol for a multi-school, cluster randomised controlled trial (INSPIRE)
There are increasing rates of internalising difficulties, particularly anxiety and depression, being reported in children and young people in England. School-based universal prevention programmes are thought to be one way of helping tackle such difficulties. This paper describes an update to a four-arm cluster randomised controlled trial (http://www.isrctn.com/ISRCTN16386254), investigating the effectiveness of three different interventions when compared to usual provision, in English primary and secondary pupils. Due to the COVID-19 pandemic, the trial was put on hold and subsequently prolonged. Data collection will now run until 2024. The key changes to the trial outlined here include clarification of the inclusion and exclusion criteria, an amended timeline reflecting changes to the recruitment period of the trial due to the COVID-19 pandemic and clarification of the data that will be included in the statistical analysis, since the second wave of the trial was disrupted due to COVID-19.

Allogeneic Stem Cell Transplantation with Sequential Melphalan-Based Conditioning in AML: Residual Morphological Blast Count Determines the Risk of Relapse
Introduction: Allogeneic hematopoietic cell transplantation (HCT) during chemotherapy-induced aplasia may offer long-term survival in acute myeloid leukemia (AML) with otherwise poor prognosis including ELN adverse risk, relapsed or refractory disease. However, the value of residual morphologic disease prior HCT in this context has not been conclusively settled until yet. Therefore, we aimed to investigate variables predicting outcome in this unique setting of sequential conditioning therapy, with a focus on
pretreatment morphologic blast count. In contrast to the most popular FLAMSA-RIC protocol, we used a melphalan-based conditioning regimen during aplasia.
Methods: We retrospectively analyzed data from 173 AML patients who underwent a sequential melphalan-based conditioning therapy between 2003 and 2015 at our centre. All patients participated either in the prospective Phase 2 BRIDGE trial (NCT01295307), the Phase 3 AML2003 study (NCT00180102) or were treated according to this protocol and underwent allogeneic HCT after melphalan-based conditioning in treatment-induced aplasia.
Results: Median bone marrow blast count prior to conditioning was 10% (range, 0â96%). Four year probabilities of EFS and OS were 34% (95% CI, 28â43%) and 43% (95% CI, 36â52%), respectively. In multivariate analysis, blast count >20% was associated with worse EFS (HR = 1.93; p = 0.009) and OS (HR = 1.80; p = 0.026). This effect was not significant anymore for HCT during 1st line therapy.
Conclusion: Allogeneic HCT in aplasia with a melphalan-based conditioning regimen has the potential to cure a subset of adverse risk AML patients, even with persistent morphological disease prior HCT. However, a high pre-transplant blast count still indicates patients with a dismal prognosis, especially in the relapsed patient group, for whom post-transplant strategies should be considered to further optimize post HCT outcome
Perturbations of mesenchymal stromal cells after allogeneic hematopoietic cell transplantation predispose for bone marrow graft- versus-host-disease
Functional impairment of the bone marrow (BM) niche has been suggested as a major reason for prolonged cytopenia and secondary graft failure after allogeneic hematopoietic cell transplantation (alloHCT). Because mesenchymal stromal cells (MSCs) serve as multipotent progenitors for several niche components in the BM, they might play a key role in this process. We used collagenase digested trephine biopsies to directly quantify MSCs in 73 patients before (n = 18) and/or after alloHCT (n = 65). For the first time, we demonstrate that acute graft-versus-host disease (aGvHD, n = 39) is associated with a significant decrease in MSC numbers. MSC reduction can be observed even before the clinical onset of aGvHD (n = 10). Assessing MSCs instantly after biopsy collection revealed phenotypic and functional differences depending on the occurrence of aGvHD. These differences vanished during ex vivo expansion. The MSC endotypes observed revealed an enhanced population of donor-derived classical dendritic cells type 1 and alloreactive T cells as the causing agent for compartmental inflammation and MSC damage before clinical onset of aGvHD was ascertained. In conclusion, MSCs endotypes may constitute a predisposing conductor of alloreactivity after alloHCT preceding the clinical diagnosis of aGvHD
In-Space Utilisation of Asteroids::âAnswers to Questions from the Asteroid Minersâ
The aim of the Asteroid Science Intersections with In-ÂSpace Mine Engineering (ASIME) 2016 conference on September 21-Ââ22, 2016 in Luxembourg City wasto provide an environment for the detailed discussion of the specific properties of asteroids, with the engineering needs of space missions that utilize asteroids.The ASIME 2016 Conference produced a layered record of discussions from theasteroid scientists and the asteroid miners to understand each otherâs key concerns and to address key scientific questions from the asteroid mining companies: Planetary Resources, Deep Space Industries and TransAstra. These Questions were the focus of the two day conference, were addressed byscientists inside and outside of the ASIME Conference and are the focus ofthis White Paper.The Questions from the asteroid mining companies have been sorted into the three asteroid science themes: 1) survey, 2) surface and 3) subsurface and 4)Other. The answers to those Questions have been provided by the scientists with their conference presentations or edited directly into an early open-Ââaccess collaborative Google document (August 2016-ÂâOctober 2016), or inserted byA. Graps using additional reference materials. During the ASIME 2016 last two-Ââhours, the scientists turned the Questions from the Asteroid Miners around by presenting their own key concerns: Questions from the Asteroid Scientists. These answers in this White Paper will point to the Science Knowledge Gaps (SKGs) for advancing the asteroid in-Ââspace resource utilisation domain
