The purine analogs (PAs) cladribine and pentostatin have transformed the prognosis of hairy cell leukemia (HCL). However, some patients still relapse after PAs, or fail to reach an optimal response, and new agents are needed to further improve treatment outcome. We retrospectively studied 41 HCL patients from 10 centers in France and Belgium, who received 49 treatment courses with the anti-CD20 monoclonal antibody rituximab. Most of the patients were treated at relapse (84 % of cases) and rituximab was combined to a PA in 41 % of cases. Overall, response rate is 90 % including 71 % complete hematologic responses (CHRs). Frontline treatment, combination therapy, and absolute neutrophil count were associated with response in multivariate analysis. Three-year relapse-free and overall survivals are 68 and 90 %, respectively. When combined to a PA, rituximab yields a 100 % response rate, even beyond frontline therapy. In contrast, response rate is only 82 % (59 % CHR) when rituximab is used alone. In this latter setting, relapse rate is 56 % and median time to relapse is 17.5 months. All eight patients who were treated two times with the antibody responded again to retreatment. We confirm the high efficacy of the combination rituximab + PA. However, when rituximab is used as monotherapy, response rate is lower and the high relapse rate is a concern. Prospective clinical trials are needed to confirm the superiority of the combination rituximab + PA over PA alone, both as frontline therapy and at relapse. [less ▲]

Comment évaluer une compétence ? Comment garantir que la performance d’un individu dans une situation d’évaluation se répétera dans une autre situation ? Ces questions sont au cœur du présent ouvrage, réécriture d’une thèse de doctorat en sciences de l’éducation consacrée à l’évaluation des compétences professionnelles. On y suit l’évolution d’une réflexion scientifique à propos des notions et présupposés théoriques qui fondent les recommandations méthodologiques en matière d’évaluation des compétences. Au fil de l’ouvrage, cette réflexion instaure un va-et-vient continu entre la littérature relative à ces questions et une démarche expérimentale appelant des analyses qualitatives et des analyses quantitatives à propos des idées et concepts issus de cette littérature. Deux dimensions sont particulièrement discutées : la notion de famille de situations et le lien présupposé entre performance et réflexivité. Dans ce cadre, les apports du courant de la didactique professionnelle sur la question de l’évaluation des compétences sont mis à l’épreuve.

Compliant mechanisms such as tape springs are often used on satellites to deploy appendices, e.g. solar panels, antennas, telescopes and solar sails. Their main advantage comes from the fact that their motion results from the elastic deformation of structural components, unlike usual hinges or prismatic joints, the motion of which is dictated by contact surfaces. No actuators or external energy sources are required and the deployment is purely passive, which appears as a decisive feature for the design of low-cost missions with small satellites or cubesats. The mechanical behaviour of a tape spring is intrinsically complex and nonlinear involving buckling, hysteresis and self-locking phenomena. High-fidelity mechanical models are then needed to get a detailed understanding of the deployment process, improve the design and predict the actual behaviour in the space 0-g environment. In the majority of the previous works, dynamic simulations were performed without any physical representation of the structural damping. These simulations could be successfully achieved because of the presence of numerical damping in the transient solver. However, in this case, the dynamic response turns out to be quite sensitive to the amount of numerical dissipation, so that the predictive capabilities of the model are questionable. In this work based on numerical case studies, we show that the dynamic simulation of a tape spring can be made less sensitive to numerical parameters when the structural dissipation is taken into account.

We conducted a questionnaire survey of the 565 European Society for Blood and Marrow Transplantation centers to analyze the outcome of allogeneic hematopoietic stem cell transplantation (alloSCT) in recipients of solid organ transplantation (SOT). We investigated 28 patients with malignant (N=22) or nonmalignant diseases (N=6), who underwent 31 alloSCT procedures: 12 after kidney, 13 after liver, and three after heart transplantation. The incidence of solid organ graft failure at 60 months after first alloSCT was 33% (95% confidence interval [CI], 16–51%) for all patients, 15% (95% CI, 2–40%) for liver recipients, and 50% (95% CI, 19–75%) for kidney recipients (p = 0.06). The relapse rate after alloSCT (22%) was low following transplantation for malignant disorders, despite advanced stages of malignancy. Overall survival at 60 months after first alloSCT was 40% (95% CI, 19–60%) for all patients, 51% (95% CI, 16–86%) for liver recipients, and 42% (95% CI, 14–70%) for kidney recipients (p = 0.39). In summary, we show that selected SOT recipients suffering from hematologic disorders may benefit from alloSCT and experience enhanced long-term survival without loss of organ function. [less ▲]

Objectives: We evaluated azacitidine (VidazaH) safety and efficacy in patients with myelodysplastic syndrome (MDS), acute myeloid leukaemia (AML), and chronic myelomonocytic leukaemia (CMML), in a real-life setting. Treatment response, dose, and schedule were assessed. Methods: This non-interventional, post-marketing survey included 49/50 patients receiving azacitidine at 14 Belgian haematology centres from 2010–2012. Treatment-emergent adverse events (TEAEs), including treatment-related TEAEs, and serious TEAEs (TESAEs) were recorded throughout the study. Treatment response [complete response (CR), partial response (PR), haematological improvement (HI), stable disease (SD), treatment failure (TF)) and transfusion-independence (TI) were evaluated at completion of a 1-year observation period (1YOP) or at treatment discontinuation, and overall survival (OS), at study conclusion. Results: The median age of patients was 74.7 (range: 43.9–87.8) years; 69.4% had MDS, 26.5% had primary or secondary AML, and 4.1% had CMML. Treatment-related TEAEs, grade 3–4 TEAEs, and TESAEs were reported in 67.3%, 28.6%, and 18.4% of patients, respectively. During 1YOP, patients received a median of 7 (1–12) treatment cycles. Treatment response was assessed for 38/49 patients. Among MDS and CMML patients (n529), 41.4% had CR, PR, or HI, 41.4% had SD, and 17.2% had TF. Among AML patients (n59), 44.4% had CR or PR, 33.3% had SD, and 22.2% had TF. TI was observed in 14/32 (43.8%) patients who were transfusion-dependent at baseline. Median (95% confidence interval) OS was 490 (326–555) days; 1-year OS estimate was 0.571 (0.422–0.696). Conclusions: Our data support previous findings that azacitidine has a clinically acceptable safety profile and shows efficacy. [less ▲]

Generalized-alpha methods are very popular in structural dynamics. They are methods of Newmark type and combine favourable stability properties with second order convergence for unconstrained second order systems in linear spaces. Recently, they were extended to constrained systems in flexible multibody dynamics that have a configuration space with Lie group structure. In the present paper, the convergence of these Lie group methods is analysed by a coupled one-step error recursion for differential and algebraic solution components. It is shown that spurious oscillations in the transient phase result from order reduction that may be avoided by a perturbation of starting values or by index reduction. Numerical tests for a benchmark problem from the literature illustrate the results of the theoretical investigations. [less ▲]

Introduction: Dipeptidyl peptidase-4 (DPP-4) inhibitors (gliptins) occupy a growing place in the armamentarium of drugs used for the management of hyperglycemia in type 2 diabetes, although some safety concerns have been raised in recent years. Areas covered: An updated review providing an analysis of available safety data (meta-analyses, randomized controlled trials, observational cohort and case-control studies and pharmacovigilance reports) with five commercialized DPP-4 inhibitors (sitagliptin, vildagliptin, saxagliptin, alogliptin, linagliptin). A special focus is given to overall safety profile; pancreatic adverse events (AEs) (acute pancreatitis, pancreatic cancer); overall cardiovascular safety (myocardial infarction and stroke); congestive heart failure concern and finally, safety in special populations (elderly, renal impairment). Expert opinion: The good tolerance/safety profile of DPP-4 inhibitors has been largely confirmed, including in more fragile populations (elderly, renal impairment) with almost no increased risk of infection or gastrointestinal AEs, no weight gain and a minimal risk of hypoglycemia. Although an increased risk of acute pancreatitis and pancreatic cancer was suspected, the complete set of available data appears reassuring so far. Cardiovascular safety of DPP-4 inhibitors has been proven but an unexpected increased risk of heart failure has been reported which should be confirmed in ongoing trials and better understood. Further postmarketing surveillance is recommended. [less ▲]

Traduction française du célèbre chapitre de Peter Carruthers, "HOP over FOR, HOT Theory". L'auteur y soutient que les théories représentationnelles de premier ordre (Dretske, Tye, et alii) et les théories actualistes de la pensée d'ordre supérieur (e.g., Rosenthal) se heurtent à deux sérieuses difficultés: l'incapacité à rendre compte des concepts d'expérience recognitionnels et l'incapacité à expliquer pourquoi certains états sont phénoménalement conscients et d'autres non. P. Carruthers introduit et défend une théorie alternative, d'après laquelle un état mental est phénoménalement conscient si et seulement s'il est mis à la disposition d'une pensée d'ordre supérieur possible. Cette théorie est baptisée théorie dispositionnelle de la pensée d'ordre supérieur ou "théorie du double contenu". [less ▲]

This report compares two important corridor migrations to Belgium in order to better understand the variation in several dimensions of Turkish and Moroccan immigrants’ integration – in particular, labour market, education and citizenship. It is based on an original methodology combining three different data sources (an analysis of the legal and political frameworks, a quantitative analysis, and a survey). It aims to test the INTERACT project’s main hypothesis which conceives of integration as a three-way process. This report provides insight on integration from the immigration country perspective but also from the countries of origin; it appraises the impact that Turkey and Morocco may have on the integration of their migrants in Belgium. The main findings are the following. Firstly, the countries of origin may have an impact on integration when emigration starts. Secondly, countries of origin may have a positive or negative impact on some integration dimensions (citizenship) but no obvious impact on others (education and labour market). In their efforts to maintain and develop links and to protect migrants’ rights abroad, countries of origin can thus facilitate integration, but indirectly. [less ▲]

Faced with the inevitable depletion of fossil resources, agricultural productions have rapidly emerged as promising renewable alternatives. Particularly, the conversion of lignocellulosic materials has nowadays opened new vistas for the production of energy, biofuels and chemicals. In this literature review, microwave technology is described as an original heating source either for the thermochemical conversions (at temperatures up to 400°C) of lignocellulose into biofuels or the pretreatment (below 400°C) and further hydrolysis of lignocellulose into bioethanol and other valuable chemicals. Advantages of microwave approaches include a commonly observed acceleration in reaction rate and improved selectivities and yields. [less ▲]
