Description: Cet ouvrage sonde deux grands types de transfert interlinguistique : la traduction professionnelle, enseignée dans les écoles et instituts de formation de traducteurs, et la traduction didactique (thème/version), pratiquée en enseignement des langues. Les auteurs des textes réunis ici, tous des pédagogues d'expérience, tentent de répondre à quelques-unes des questions fondamentales du domaine : en quoi l'enseignement de la traduction professionnelle se distingue-t-il des exercices de traduction didactique ? Comment enseigner à bien comprendre les textes avant de les traduire ? Comment convient-il d'évaluer les traductions ? La puissance d'Internet peut-elle être mise au service de l'enseignement de la traduction ? Quel métalangage utilise-t-on dans les cours de traduction ? Pourquoi est-il important d'inculquer aux étudiants des habitudes dénominatives ? L'introspection à haute voix (think-aloud protocols) peut-elle contribuer à améliorer la pédagogie de la traduction ? Autant de questions qui trouvent dans ce collectif des éléments de réponse propres à faire progresser la pédagogie de la traduction et à stimuler la recherche.

Description: Ce recueil de portraits nous fait pénétrer dans l’intimité de dix traducteurs qui appartiennent à diverses époques : XVIe, XVIIIe, XIXe et XXe siècles. Les textes traduits vont de l’article de presse aux Saintes Écritures, en passant par la tragédie grecque, le roman, la poésie, le conte, le « polar » et les traités de droit. Réintroduisant la subjectivité dans le discours sur la traduction, ces portraits contribuent au nécessaire recentrement de l’attention sur la personne du traducteur. Lorsqu’il a entrepris telle ou telle traduction, quelle était sa visée réelle ? S’est-il plié docilement aux contraintes inhérentes à cet exercice de réénonciation interlinguistique et interculturelle ? A-t-il transgressé certaines de ces contraintes ? Où a-t-il travaillé ? À quelle époque ? Pour qui ? À quelle fin ? Dans quelles circonstances ? Quels facteurs externes ont pu infléchir sa manière de traduire, l’amener à modifier le texte original, voire à s’autocensurer ? Autant de questions dont il faut chercher les réponses en dehors des textes traduits. « Cet ouvrage est original par les liens qu’il tisse entre destinées individuelles et contraintes collectives, entre créativité d’une personne et déterminations historiques. Il est original aussi car il est quasiment le premier du genre. Ce volume vient à son heure non seulement parce que les portraits sont vivants, mais aussi parce qu’il peut à sa manière redynamiser la traductologie, parfois asséchée dans ses spéculations, souvent oublieuse du passé. » Yves Gambier, Université de Turku, Finlande.

Description: We study the spin evolution of close-in planets in multi-body systems and present a very general formulation of the spin-orbit problem. This includes a simple way to probe the spin dynamics from the orbital perturbations, a new method for computing forced librations and tidal deformation, and general expressions for the tidal torque and capture probabilities in resonance. We show that planet–planet perturbations can drive the spin of Earth-size planets into asynchronous or chaotic states, even for nearly circular orbits. We apply our results to Mercury and to the KOI-1599 system of two super-Earths in a 3/2 mean motion resonance.

Description: Adoptive immunotherapy based on the injection of allogenic cytotoxic T-lymphocytes (CTL) during or after bone marrow transplant (BMT) has established itself as a potent anti-neoplastic treatment for several malignancies. However this approach is limited by the occurence of graft versus host disease (GVH). Using a previously described murine adoptive immunotherapy model where donor and recipient are mismatched for a single dominant minor histocompatibility antigen (H7a), and where a powerful anti-neoplastic effect is seen without GVH, we sought to determine what rendered cancer cells more vulnerable than normal cells to immune attack. B10.H7a mice were lethally irradiated and reconstituted with B10.H7b (H7a negative) T-depleted bone marrow. On the day of transplant, these mice received a B16.F10 (H7a positive) melanoma challenge. Adoptive transfer of splenocytes obtained from B10.H7b mice previously immunized with B10.H7a splenocytes was performed on day 7 post BMT. Following transfer of those splenocytes containing primed anti-H7a CTL, neither GVH nor vitiligo was noted in recipients despite the fact that H7a is expressed in all tissues and organs. 50% of treated mice, versus 0% of controls rejected the tumor and survived 100 days. Overall survival was increased to 80% when adoptive transfer was carried on day 3 post BMT. The injection of anti-H7b CTL had no effect on melanoma growth. Thus, the anti-tumor activity was T-cell receptor recognition dependent and not a mere bystander effect. In treated mice but not in controls, tumor histology and flow cytometry revealed important CTL infiltration (80% of those CTL being MHC-H7a tetramer positive), increased expression of MHC class I molecules (MHC I) at melanoma cell surface, expression of Rae-1 (an NKG2D ligand), tumor necrosis and decreased angiogenesis. Importantly, normal skin in treated or control animals showed no increased expression of MHC I or Rae-1. B16.F10 melanoma cells express almost no MHC I, and no Rae-1 when cultured in vitro. Co-incubation of B16.F10 cells with INFγ leads to increased MHC I expression but no induction of Rae-1 expression, implying that at least a second factor is present in vivo to account for the expression of this stress ligand. An additional role for INFγ was evidenced when anti-H7a CTL were injected in INFγ receptor knock-out recipients. The angiostatic effect noted after anti-H7a CTL injection was abrogated and no mice were cured. Thus, INFγ-mediated angiostasis on the tumor stroma was crucial for the inhibition of cancer progression. Conclusion: in our model, the differential immune susceptibility of tumor versus normal cells appears to stem from the fact that neoplastic cells are induced to express more MHC I and stress ligands such as Rae-1. Those can respectively increase target antigen density at the cell surface and mediate CTL co-stimulation or cytotoxicity, through NKG2D receptors. Strategies exploiting stress ligand induction as well as the effect of INFγ on MHC expression and angiostasis may contribute to successfully separate anti-tumor from GVH effects.

Description: Many new therapeutic agents have been approved for follicular lymphoma (FL) but none appear to be curative. Despite novel agents, some patients (pts) experience early relapse, become chemorefractory or suffer transformation into more aggressive lymphomas. Options for these pts are limited. High dose chemotherapy with autologous stem transplant (ASCT) prolongs progression free survival (PFS) and overall survival (OS) in FL pts in first relapse and registry data shows favorable outcome with ASCT in cases of histologic transformation. However, ASCT is usually not curative. Myeloablative allogeneic transplant (MT) has produced long term PFS but is hampered by significant non relapse mortality (NRM) while nonmyeloablative transplant (NMT) has a higher relapse rate compared to MT especially in high risk pts. Finally, many transplant studies have excluded these high risk pts such as those with chemorefractory or transformed disease. We hypothesized that a tandem transplant consisting of an ASCT followed by a NMT would confer the same benefit as a MT without the associated high NRM by separating the high dose chemotherapy from graft versus host disease (GVHD) while preserving the graft versus lymphoma effect. The goal of our study was to improve long term PFS in high risk FL pts. We therefore initiated a prospective protocol in April 2003, for pts with high risk relapsed FL as defined by chemorefractory disease, early 1st relapse, 〉1st relapse or transformation into aggressive histology. At least one therapy was attempted to document chemosensitivity prior to ASCT. However, regardless of disease status prior to transplant, pts underwent ASCT followed 3 months later by an outpatient NMT from an HLA-identical sibling. NMT comprised 5 days of fludarabine 30 mg/m2/day and cyclophosphamide 300mg/m2/day followed by an infusion of 〉2x106CD34+ cells/kg. GVHD prophylaxis, chosen to take advantage of the low incidence of acute (a) GVHD and the putative protective effect of chronic (c) GVHD, consisted of tacrolimus starting on day (D) - 8 to achieve levels of 8-12 nmol/L then tapered off by D+100 or D+180 depending on disease risk and of mycophenolate mofetil 1g bid from D+2 to D+50. We previously reported on 27 pts with a follow-up (f/u) of 3 years (yrs). We now report a larger cohort of 40 pts with a median f/u of 8 yrs. Up until July 2015, 40 pts were enrolled with a median age of 50 yrs (34-65). Pts had previously been treated with a median of 3 lines of therapy (2-6). Median time from diagnosis to ASCT was 33 months. Disease status at ASCT was: 14 CR, 16 PR and 10 refractory. Conditioning for ASCT included BEAM/BEAC (n=39), and Cy-TBI (n=1). In addition, 4 pts received radiotherapy after ASCT to sites of previously bulky disease. Median time between ASCT and NMT was 138 days (75-238). Pre NMT disease status was: 25 CR, 12 PR and 3 refractory. Engraftment was prompt in all pts after ASCT and median neutrophil and platelet recovery were respectively 13 days (0-19) and 0 day (0-18) post NMT. Seven pts (18%) developed aGVHD: 2 grade II and 5 grade III. Overall, 29 pts (73%) developed cGVHD: 1 mild, 13 moderate and 15 severe according to NIH revised criteria. Median time to discontinuation of immunosuppression was 22 months. To date, 2 pts have progressed at 11 and 59 months post NMT (one died from relapse and one is now in CR after chemotherapy and DLI) and 5 pts died from either GVHD related complications (n=4) or unknown cause (n=1). All pts alive at last f/u were in CR. With a median f/u of 8 yrs in surviving pts (1-12), OS is 95% at 3 and 5 yrs and 82% at 8 yrs. PFS is 92% at 3yrs, 89% at 5 yrs and 80% at 8 yrs. NRM and relapse rate at 8 yrs are 18% and 6% respectively. Based on our current results in 40 pts, we conclude that ASCT followed by sibling NMT for high risk relapsed FL is associated with excellent disease response and PFS. Furthermore, this tandem strategy appears to be safe and well tolerated. The incidence of cGVHD remains high but could in part explain the impressive PFS in this high risk cohort. This approach should now be further explored in a multi institution setting, include matched unrelated donors and consider the addition of rituximab post-transplant to reduce the incidence and severity of cGVHD with the hope that relapse will not be increased.

Description: Introduction: High dose chemotherapy (HDT) and autologous hematopoietic cell transplantation (AHCT) are considered standard of care as first line therapy in mantle cell lymphoma (Dreyling et al., 2005; Geisler et al., 2012) and in first line refractory and chemosensitive relapse Non-Hodgkin Lymphoma (NHL) (Philip et al., 1995) . The development of hematopoietic cell transplant comorbidity index (HCT-CI) (Sorror et al., 2009) for recipient selection and transplant risk evaluation have impacted on patient selection. Over the last decade, most transplant program have seen an increase in the median age of AHCT recipients(McCarthy et al., 2013). Limited data are available to optimise elderly patients selection for transplantation while minimising the risk of treatment related toxicity and mortality (TRM). The goal of this study was to identify factors impacting the safety and efficacy of AHCT in the elderly NHL patients in order to better select those who will benefit from this intervention. Method: This is a single center, retrospective study examining outcomes of AHCT in elderly patients (≥60 years old) with NHL. Between January 1st, 2008 and January 1st, 2015, 90 patients met the inclusion criteria and were included in the study. Patients signed an informed consent and the ethics committee of our institution approved the study. Progression-free-survival (PFS) and overall survival (OS) were analyzed according to age at time of transplantation, HCT-CI, lymphoma histology and disease status at time of transplant. Toxicities were analyzed according to age and HCT-CI. Results: Median age at time of NHL diagnostic was 60 years (range 42 to 68) and 63 years at time of transplant (range 60 to 69). One third (33%) of our cohort was ≥65 years old. Histologic sub-type was mainly composed of follicular (36%), mantle cell (20%) and large B-cell lymphoma (38%). 50% of patients had high-risk disease and 31% had low risk disease. HCT-CI was low-risk in 34%, intermediate risk in 40% and high-risk disease in 26%. BEAM/BEAC conditioning regimen was used in 94%. The median graft CD34+/kg cell dose infused was 4.87. The median time to neutrophil engraftment was 10 days (range 8 to 14 days) and platelet recovery was 16 days (range 11 to 43 days). The incidence of febrile neutropenia was 92% with 2% admission to the intensive care unit (ICU) with no difference between patients younger or ≥65 years old. Our cohort received a median of 8 days of antibiotics (range 0 to 41 days). Absolute lymphocyte count 〈 0,3 X 103 cells/uL at 14 days after transplant was associated with higher incidence of septic choc (p=0,024) and ICU admission (p=0,034). Age ≥65 year was not associated with an increase TRM and was surprisingly associated with less total parenteral nutrition (p=0,046) and narcotics uses (P=0,011). The median length of stay was 26 days. The median follow-up was 27 months (range, 1 to 87), median PFS of 46 months (Confidence Interval (CI); 95%, 24,4-67,6) (graph 1) and OS not reached (graph 2). The estimated 5 years OS is 62% and PFS is 40%. Transplant related mortality (TRM) was only 1% at 100 days and 2% at 1year after transplant. The only 2 patients who died from TRM died from cardiac arrest (1 month) and from an unknown cause (3 months). The 1-year progression rate was 30% (graph 3) and mortality rate only 12%. Progressive disease status following first line therapy was associated with a worse PFS compared to the achievement of a complete remission (Hazard Ratio (HR) 2,77; CI 95%, 1,18; 6,49). Progressive disease status at time of transplant was also associated with a lower PFS (HR 9,30: CI 95% 2,55 to 33,92) and OS (HR 13,44: CI 95% 2,68 to 67,48). HCT-CI score did not correlate with OS. International Prognostic Index (IPI), age and treatment type did not influence PFS or OS. Surprisingly, HCT-CI score did not correlate with toxicities, morbidity or mortality. Conclusion: In this single center retrospective study of elderly patients with NHL, AHCT was proven to be safe and effective. Progressive disease at the time of transplant was associated with worse PFS and OS. HCT-CI did not allow the categorization of patients in different prognostics group. Lymphocyte count at day 14 could identify patients at significant risk of complications. Our data suggest that age alone should not exclude patients from transplantation. However, HDT and AHCT should be reserved to chemosensitive patients and avoided in the elderly patient with progressive disease. Figure 1. Figure 1. Figure 2. Figure 2. Figure 3. Figure 3.

Description: Introduction Allogeneic hematopoietic stem cell transplantation (alloHSCT) remains the only curative option for multiple myeloma (MM). Unfortunately, relapses remain frequent and randomized controlled trials have yielded equivocal conclusions. Before these trials were published, selected patients were treated with alloHSCT, but factors affecting long-term success have not been clearly defined. We have analyzed our single-center cohort of MM patients receiving a myeloablative alloHSCT in the 1990's in order to evaluate the impact of several factors on outcomes. Methods We performed a retrospective data collection on all patients treated with myeloablative alloHSCT from a sibling donor at our institution. Probabilities of overall (OS) and progression-free survival (PFS), as well as relapse, nonrelapse mortality (NRM) and graft-versus-host disease (GVHD) incidences were estimated taking competing risks into account when appropriate. Regression analysis using Cox and Fine & Gray models were used to determine factors influencing outcomes. Severity of chronic GVHD was assessed by the proportion of survivors on systemic immunosuppressive therapy. Results Between 1990 and 2001, 39 patients received a myeloablative alloHSCT. Median age was 46 years (range 24-53) and 68% had Durie-Salmon stage III disease. Twenty patients had received more than 4 cycles of prior chemotherapy and 4 patients had been treated with an autologous HSCT. Complete remission (CR) was achieved before allogeneic transplant in 31% patients. All but one donor were 6/6 HLA matches. AlloHSCT was performed within the first year of diagnosis in 69% of patients. Irradiation-based conditioning was used in 77%; stem cell source was bone marrow in 54% and peripheral blood (PB) in 46% of patients. With a median follow-up of 13 years, cumulative incidences of progression and NRM were 43% (95%CI: 26-59; Fig. 1) and 38% (22-54), respectively. Cumulative incidences of grade II-IV acute and extensive chronic GVHD were 29% (16-44) and 40% (24-55). Probabilities of 10-year OS and PFS were 33% (95%CI: 19-48; Fig. 2) and 29% (95%CI: 16-44) In multivariate analysis, the most significant protective factor against relapse was the use of PB as cell source (HR 0.34, CI: 0.14-0.82). The only protective factor for PFS was CR status before transplantation (HR 0.28, CI: 0.09-0.89). Nevertheless, the effect of these variables on overall survival was inconclusive (respectively: HR 0.51, CI 0.22-1.17, and HR 0.39, CI: 0.13-1.19). The time-dependent effect of chronic GVHD on PFS was also statistically non-significant (HR 0.47, CI: 0.14-1.59). The probability of being on systemic immunosuppressive treatment for GVHD in alive patients was 31% (CI: 13-58) at 10 years. Conclusions Myeloablative alloHSCT performed for MM in the 1990's in selected patients allowed a high probability of disease control but with major toxicity as shown by the high NRM risk. A third of patients are alive 10 years after transplantation. Achievement of CR before alloHSCT and the use of PB stem cells were protective against transplant failure. However, small sample size does not allow us to draw conclusions on the effect of other pre-transplant characteristics and GVHD on OS. The risk of relapse in our cohort being comparable to published results in frontline reduced-intensity alloHSCT, superiority of myeloablative HSCT for advanced disease can be hypothesized. Prohibitive NRM risk should encourage efforts to reduce early and late toxicity through better patient and donor selection, conditioning regimen and GVHD prophylaxis.
