A predictive classifier of poor prognosis in transplanted patients with juvenile myelomonocytic leukemia: a study on behalf of the Société Francophone de Greffe de Moelle et de Thérapie Cellulaire
Juvenile myelomonocytic leukemia (JMML) is an aggressive pediatric myeloproliferative neoplasm requiring hematopoietic stem cell transplantation (HSCT) in most cases. We retrospectively analyzed 119 JMML patients who underwent first allogeneic HSCT between 2002 and 2021. The majority (97%) carried a RAS-pathway mutation, and 62% exhibited karyotypic alterations or additional mutations in SETBP1, ASXL1, JAK3 and/or the RAS pathway. Relapse was the primary cause of death, with a 5-year cumulative incidence of 24.6% (95%CI: 17.1-32.9). Toxic deaths occurred in 12 patients, resulting in treatmentrelated mortality (TRM) of 9.0% (95%CI: 4.6-15.3). The 5-year overall (OS) and event-free survival were 73.6% (95%CI: 65.7-82.4) and 66.4% (95%CI: 58.2-75.8), respectively. Four independent adverse prognostic factors for OS were identified: age at diagnosis >2 years, time from diagnosis to HSCT >6 months, monocyte count at diagnosis >7.2x109/L, and the presence of additional genetic alterations. Based on these factors, we proposed a predictive classifier. Patients with three or more predictors (21% of the cohort) had a 5-year OS of 34.2%, whereas those with none (7%) had a 5-year OS of 100%. Our study demonstrates improved transplant outcomes compared to prior published data, which can be attributed to the synergistic impacts of a low TRM and a reduced yet still substantial relapse incidence. By integrating genetic information with clinical and hematological features, we have devised a predictive classifier. This classifier effectively identifies a subgroup of patients who are at a heightened risk of unfavorable post-transplant outcomes who would benefit novel therapeutic agents and post-transplant strategies

Victimes et bourreaux dans le théùtre de Griselda Gambaro
Ce travail se propose dâapprofondir le contexte culturel, historique et social qui sert de toile de fond au thĂ©Ăątre de Griselda Gambaro dĂšs les annĂ©es soixante. En Argentine, durant les annĂ©es de rĂ©pression, dâabord avec la dictature de Juan Carlos OnganĂa (1966] puis avec celle de Rafael Videla (1976), le thĂ©Ăątre est un espace qui sert dâexutoire, ainsi quâun moyen dâexpression qui met en scĂšne les moeurs et les comportements humains. Les piĂšces analysĂ©es dans ce travail dĂ©noncent la perversion de la dictature, ainsi que les exactions infligĂ©es par les tortionnaires sur leurs victimes. Dans un contexte politique et social dĂ©terminĂ©, le thĂšme de « la victime et du bourreau » est une constante dans ce thĂ©Ăątre qui met lâaccent sur les dangers de la coercition et de lâarbitraire exercĂ©s par un pouvoir tyrannique.This studying attemps to go more deeply into the cultural, historical and social context which is the backdrop to Griselda Gambaroâs theatrical world from the 1960s onwards. In Argentina during the years of repression, first under the dictatorship of Juan Carlos OnganĂa (1966) then that of Rafael Videla (1976), the theatre was a form of escapism, yet at the same time a means of expression staging human mores and behaviour. The plays analysed here denounce the perversion of dictatorship as well as the suffering inflicted on victims by their torturers. In this specific political and social context, the theme of "victim and torturer" is a constant in these theatrical works, which underline the dangers of coercion and arbitrary decisions exercised by tyrannical power
Intoxication volontaire par une tisane de feuilles de Datura
Le Datura appartient à la famille des Solanacées, plante
contenant trois alcaloĂŻdes toxiques : atropine, scopolamine
et hyoscine. Utilisé en toxicomanie pour ses propriétés hallucinogÚnes,
il peut ĂȘtre responsable d'intoxication volontaire.
Toute la plante est toxique et son ingestion entraĂźne l'apparition
d'un syndrome anticholinergique. Nous rapportons
ici un cas d'intoxication volontaire dont le tableau clinique
est celui d'une intoxication atropinique (agitation, hallucination,
mydriase, tachycardie, rétention urinaire). Le traitement
a été symptomatique et l'évolution favorable. Les analyses
chromatographiques (RemediÂź) des urines du patient
ainsi que d'une décoction retrouvée en sa possession ont
permis de confirmer l'hypothÚse d'une intoxication aiguë au
Datura
Choice of Initial Brain Imaging in Patients with Suspected Acute Stroke: STROKE69, a Population-Based Study
International audienceBackground: In patients with suspected stroke, brain imaging is recommended in the acute phase for appropriate management and treatment. Both computed tomography (CT) and magnetic resonance imaging (MRI) are considered reasonable choices for initial brain imaging. When both techniques are available, choosing one or the other might be associated with specific factors related either to patients, stroke symptoms, and severity or management organization. Methods: The study was performed within the STROKE 69 database, a population-based cohort of all adult patients with suspected stroke admitted in one of the emergency departments (ED), primary stroke center, or stroke center of the RhĂŽne County, from November 2015 to December 2016. Patients were included if they were admitted within 24 h following either symptom onset or last known normal. To identify factors potentially associated with the choice of initial brain imaging, a multivariate logistic regression was performed. Results: Among the 3,244 patients with suspected stroke enrolled in the STROKE69 cohort, 3,107 (95.8%) underwent brain imaging within the first 24 h after admission. Among those 74.6% underwent CT as initial imaging while 25.4% had an MRI. In multivariate analyses, several factors were associated with a lower probability of having an MRI as initial brain imaging versus CT. These were either patient characteristics: older age (>80 years old, OR 0.39 [95% CI 0.28â0.54]), preexisting disability (OR 0.55 [95% CI 0.36â0.84]), use of anticoagulants (OR 0.52 [95% CI 0.33â0.81]), stroke characteristics: stroke of unknown onset (OR 0.42 [95% CI 0.31â0.58]) or factors associated with overall management: onset-to-door time (>6 h, OR 0.38 [95% CI 0.23â0.60]), initial admission to ED (OR 0.02 [95% CI 0.02â0.04]) or intensive care unit (OR 0.01 [95% CI 0.001â0.08]), personal transport (OR 0.66 [95% CI 0.45â0.96]), and admission during working hours (OR 0.65 [95% CI 0.51â0.84]). Conclusions: Besides CT or MRI availability, a number of other parameters could influence the choice of first imaging in case of stroke suspicion. These are related to patient characteristics, type of stroke symptoms, and type of organization
Les formes de reconnaissance de lâautre en question
Sous ses diffĂ©rentes formes, la relation Ă lâautre fonde et travaille, depuis toujours tout ou partie des sociĂ©tĂ©s humaines. De connaissance, de mĂ©connaissance ou dâinconnaissance, cette relation nâest pas Ă penser comme un tiers-ĂȘtre entre lâUn et lâAutre. Elle est bien plutĂŽt ce qui, en deçà et au-delĂ de toute onticitĂ©, donne Ă ĂȘtre et lâUn et lâAutre ; mais elle nâa jamais Ă©tĂ© aussi problĂ©matique que depuis que les sociĂ©tĂ©s les plus distantes les unes des autres, sont en relation directe ou indirecte, que depuis que ce qui sâappelle "le village planĂ©taire" tente, dans le discours au moins, de raboter les diffĂ©rences, niveler les cultures, standardiser les modĂšles de consommation, limer les aspĂ©ritĂ©s, Ă©purer la planĂšte des doutes et des incertitudes devant la progression de lâĂ©conomie-monde. Celle-ci, dâailleurs, nâa de cesse, par un effet de perversion, de "marchandiser" la diffĂ©rence, câest Ă dire la relation mĂȘme Ă lâAutre. Ce mouvement tente donc de jouer sur deux tableaux contradictoires : dans le mĂȘme temps quâil pousse Ă lâuniformisation, il encourage la diffĂ©renciation et la dĂ©massification, dont il Ă©vacue le sens pour nâen garder que les signifiants
