Adequate iron chelation therapy for at least six months improves survival in transfusion-dependent patients wih lower risk myelodysplastic syndromes

Background: Most patients with myelodysplastic syndromes (MDS) require transfusions at the risk of ironoverload and associated organ damage, and death. Emerging evidence indicates that iron chelation ther-apy (ICT) could reduce mortality and improve survival in transfusion-dependent MDS patients, especiallythose classified as International Prognostic Scoring System (IPSS) Low or Intermediate-1 (Low/Int-1).Methods: Follow-up of a retrospective study. Sample included 127 Low/Int-1 MDS patients from 28 centersin Belgium. Statistical analysis stratified by duration (≥6 versus <6 months) and quality of chelation (adequate versus weak). Results: Crude chelation rate was 63% but 88% among patients with serum ferritin ≥1000 g/L. Of the 80chelated patients, 70% were chelated adequately mainly with deferasirox (26%) or deferasirox followingdeferoxamine (39%). Mortality was 70% among non-chelated, 40% among chelated, 32% among patientschelated ≥6 m, and 30% among patients chelated adequately; with a trend toward reduced cardiacmortality in chelated patients. Overall, median overall survival (OS) was 10.2 years for chelated and 3.1years for non-chelated patients (p < 0.001). For patients chelated ≥6 m or patients classified as adequatelychelated, median OS was 10.5 years. Mortality increased as a function of average monthly transfusionintensity (HR = 1.08, p = 0.04) but was lower in patients receiving adequate chelation or chelation ≥6 m(HR = 0.24, p < 0.001). Conclusion: Six or more months of adequate ICT is associated with markedly better overall survival. Thissuggests a possible survival benefit of ICT in transfusion-dependent patients with lower-risk MDS

Search for soft unclustered energy patterns in proton-proton collisions at 13 TeV

International audienceThe first search for soft unclustered energy patterns (SUEPs) is performed using an integrated luminosity of 138 fb$^{-1}$ of proton-proton collision data at $\sqrt{s}$ = 13 TeV collected in 2016-2018 by the CMS detector at the LHC. Such SUEPs are predicted by Hidden Valley models with a new, confining force with a large 't Hooft coupling. In events with boosted topologies, selected by high-threshold hadronic triggers, the multiplicity and sphericity of clustered tracks are used to reject the background from standard model quantum chromodynamics. With no observed excess of events over the standard model expectation, limits are set on the cross section for production via gluon fusion of a scalar mediator with SUEP-like decays
