Résumé : Importance: Vacuum aspiration is commonly used to remove retained products of conception in patients with incomplete spontaneous abortion. Scarring of the uterine cavity may occur, potentially impairing future fertility. A procedural alternative, operative hysteroscopy, has gained popularity with a presumption of better future fertility. Objective: To assess the superiority of hysteroscopy to vacuum aspiration for subsequent pregnancy in patients with incomplete spontaneous abortion who intend to have future pregnancy. Design, Setting, and Participants: The HY-PER randomized, controlled, single-blind trial included 574 patients between November 6, 2014, and May 3, 2017, with a 2-year duration of follow-up. This multicenter trial recruited patients in 15 French hospitals. Individuals aged 18 to 44 years and planned for surgery for an incomplete spontaneous abortion with plans to subsequently conceive were randomized in a 1:1 ratio. Interventions: Surgical treatment by hysteroscopy (n = 288) or vacuum aspiration (n = 286). Main Outcomes and Measures: The primary outcome was a pregnancy of at least 22 weeks' duration during 2-year follow-up. Results: The intention-to-treat analyses included 563 women (mean [SD] age, 32.6 [5.4] years). All aspiration procedures were completed. The hysteroscopic procedure could not be completed for 19 patients (7%), 18 of which were converted to vacuum aspiration (8 with inability to completely resect, 7 with insufficient visualization, 2 with anesthetic complications that required a shortened procedure, 1 with equipment failure). One hysteroscopy failed due to a false passage during cervical dilatation. During the 2-year follow-up, 177 patients (62.8%) in the hysteroscopy group and 190 (67.6%) in the vacuum aspiration (control) group achieved the primary outcome (difference, -4.8% [95% CI, -13% to 3.0%]; P =.23). The time-to-event analyses showed no statistically significant difference between groups for the primary outcome (hazard ratio, 0.87 [95% CI, 0.71 to 1.07]). Duration of surgery and hospitalization were significantly longer for hysteroscopy. Rates of new miscarriages, ectopic pregnancies, Clavien-Dindo surgical complications of grade 3 or above (requiring surgical, endoscopic, or radiological intervention or life-threatening event or death), and reinterventions to remove remaining products of conception did not differ between groups. Conclusions and Relevance: Surgical management by hysteroscopy of incomplete spontaneous abortions in patients intending to conceive again was not associated with more subsequent births or a better safety profile than vacuum aspiration. Moreover, operative hysteroscopy was not feasible in all cases. Trial Registration: ClinicalTrials.gov Identifier: NCT02201732.

Résumé : The ratios of branching fractions $\mathcal{R}(D^{*})\equiv\mathcal{B}(\bar{B}\to D^{*}\tau^{-}\bar{\nu}_{\tau})/\mathcal{B}(\bar{B}\to D^{*}\mu^{-}\bar{\nu}_{\mu})$ and $\mathcal{R}(D^{0})\equiv\mathcal{B}(B^{-}\to D^{0}\tau^{-}\bar{\nu}_{\tau})/\mathcal{B}(B^{-}\to D^{0}\mu^{-}\bar{\nu}_{\mu})$ are measured, assuming isospin symmetry, using a sample of proton-proton collision data corresponding to 3.0 fb${ }^{-1}$ of integrated luminosity recorded by the LHCb experiment during 2011 and 2012. The tau lepton is identified in the decay mode $\tau^{-}\to\mu^{-}\nu_{\tau}\bar{\nu}_{\mu}$. The measured values are $\mathcal{R}(D^{*})=0.281\pm0.018\pm0.024$ and $\mathcal{R}(D^{0})=0.441\pm0.060\pm0.066$, where the first uncertainty is statistical and the second is systematic. The correlation between these measurements is $\rho=-0.43$. Results are consistent with the current average of these quantities and are at a combined 1.9 standard deviations from the predictions based on lepton flavor universality in the Standard Model.

Résumé : The first experimental information on the strong interaction between $\Lambda$ and $\Xi^-$ strange baryons is presented in this Letter. The correlation function of $\Lambda-\Xi^-$ and $\overline{\Lambda}-\overline{\Xi}^{+}$ pairs produced in high-multiplicity proton-proton (pp) collisions at $\sqrt{s}$ = 13 TeV at the LHC is measured as a function of the relative momentum of the pair. The femtoscopy method is used to calculate the correlation function, which is then compared with theoretical expectations obtained using a meson exchange model, chiral effective field theory, and Lattice QCD calculations close to the physical point. Data support predictions of small scattering parameters while discarding versions with large ones, thus suggesting a weak $\Lambda-\Xi^{-}$ interaction. The limited statistical significance of the data does not yet allow one to constrain the effects of coupled channels like $\Sigma-\Xi$ and N$-\Omega$.

Résumé : The interactions of kaons (K) and antikaons ($\mathrm{\overline{K}}$) with few nucleons (N) were studied so far using kaonic atom data and measurements of kaon production and interaction yields in nuclei. Some details of the three-body KNN and $\mathrm{\overline{K}}$NN dynamics are still not well understood, mainly due to the overlap with multi-nucleon interactions in nuclei. An alternative method to probe the dynamics of three-body systems with kaons is to study the final state interaction within triplet of particles emitted in pp collisions at the Large Hadron Collider, which are free from effects due to the presence of bound nucleons. This Letter reports the first femtoscopic study of p$-$p$-$K$^+$ and p$-$p$-$K$^-$ correlations measured in high-multiplicity pp collisions at $\sqrt{s}$ = 13 TeV by the ALICE Collaboration. The analysis shows that the measured p$-$p$-$K$^+$ and p$-$p$-$K$^-$ correlation functions can be interpreted in terms of pairwise interactions in the triplets, indicating that the dynamics of such systems is dominated by the two-body interactions without significant contributions from three-body effects or bound states.

Résumé : The measurement of the production of f0(980) in inelastic pp collisions at s=5.02 TeV is presented. This is the first reported measurement of inclusive f0(980) yield at LHC energies. The production is measured at midrapidity, |y|<0.5, in a wide transverse momentum range, 0<pT<16 GeV/c, by reconstructing the resonance in the f0(980)→π+π− hadronic decay channel using the ALICE detector. The pT-differential yields are compared to those of pions, protons and ϕ mesons as well as to predictions from the HERWIG 7.2 QCD-inspired Monte Carlo event generator and calculations from a coalescence model that uses the AMPT model as an input. The ratio of the pT-integrated yield of f0(980) relative to pions is compared to measurements in e+e− and pp collisions at lower energies and predictions from statistical hadronisation models and HERWIG 7.2. A mild collision energy dependence of the f0(980) to pion production is observed in pp collisions from SPS to LHC energies. All considered models underpredict the pT-integrated 2f0(980)/(π+ +π−) ratio. The prediction from the canonical statistical hadronisation model assuming a zero total strangeness content of f0(980) is consistent with the data within 1.9σ and is the closest to the data. The results provide an essential reference for future measurements of the particle yield and nuclear modification in p–Pb and Pb–Pb collisions, which have been proposed to be instrumental to probe the elusive nature and quark composition of the f0(980) scalar meson.
