    The western corn rootworm, Diabrotica virgifera virgifera (Coleoptera: Chrysomelidae), is one of the most destructive pests of corn in North America and is currently invading Europe. The two major invasive outbreaks of rootworm in Europe have occurred, in North-West Italy and in Central and South-Eastern Europe. These two outbreaks originated from independent introductions from North America. Secondary contact probably occurred in North Italy between these two outbreaks, in 2008. We used 13 microsatellite markers to conduct a population genetics study, to demonstrate that this geographic contact resulted in a zone of admixture in the Italian region of Veneto. We show that i) genetic variation is greater in the contact zone than in the parental outbreaks; ii) several signs of admixture were detected in some Venetian samples, in a Bayesian analysis of the population structure and in an approximate Bayesian computation analysis of historical scenarios and, finally, iii) allelic frequency clines were observed at microsatellite loci. The contact between the invasive outbreaks in North-West Italy and Central and South-Eastern Europe resulted in a zone of admixture, with particular characteristics. The evolutionary implications of the existence of a zone of admixture in Northern Italy and their possible impact on the invasion success of the western corn rootworm are discussed

    Maladaptive facet trait profiles and psychopathology: a person‑centered assessment approach

    Get PDF
    Person-centered approaches in personality allow greater understanding of how different subpopulations with specific person- ality profiles are linked with relevant outcomes. Studies under the Five Factor Model agree on the observation of a Resilient, an Undercontrolled and an Overcontrolled profile. However, studies using maladaptive traits are much more limited. The present research identify personality profiles based on the 25 maladaptative facet and examined the relationships with per- sonality dysfunctioning, internalizing and externalizing symptoms. A mixed sample composed of community adults (n = 742) and patients (n = 312) completed the Personality Inventory for DSM-5 Short Form, the Inventory of Depression and Anxiety Symptoms-II, Externalizing Spectrum Inventory–Brief From, the 12 items Spanish version of the WHO Disability Assessment Schedule II and Level of Personality Functioning Scale- Brief Form 2.0. Latent profile analysis was performed on PID-5-SF score. The scores on internalizing, externalizing and functioning were compared across the profiles. Four profiles emerged: Resilient, Undercontrolled, Overcontrolled, and Ordinary type. The Overcontrolled and Undercon- trolled types showed higher scores on pathology scales. While the Overcontrolled profile appeared more related to inter- nalizing symptoms and impairment in self-functioning, the Undercontrolled profile was more linked to higher scores on externalizing symptoms and interpersonal dysfunctioning.Funding for open access publishing: Universidad de Huelva/ CBUA This work was supported by the grant “Reliable and clinical relevant change of Inventory of Depression and Anxiety Symptoms II – IDAS-II: a longitudinal clinical utility study (RELY-IDAS-II)”, project PID2020-116187RB-I00 on Proyectos I + D + i 2020 “Retos del Conocimiento” provided by Ministerio de Ciencia e Innovación (Spain)

    Introduction: Many treatment regimens have been evaluated in transplant-ineligible (TIE) patients with newly diagnosed multiple myeloma (NDMM). The objective of this study was to compare the efficacy of relevant therapies for the treatment of TIE patients with NDMM. Methods: Progression-free survival (PFS) and overall survival (OS) from large randomised controlled trials (RCTs) evaluating different treatment options for TIE patients with NDMM were compared in a network meta-analysis (NMA). The NMA includes recent primary and long-term OS readouts from SWOG S0777, ENDURANCE, MAIA, and ALCYONE. Relevant trials were identified through a systematic literature review. Relative efficacy measures (i.e., hazard ratios [HRs] for PFS and OS) were extracted and synthesised in random-effects NMAs. Results: A total of 122 publications describing 45 unique RCTs was identified. Continuous lenalidomide/dexamethasone (Rd) was selected as the referent comparator. Daratumumab-containing treatments (daratumumab/lenalidomide/dexamethasone [D-Rd], daratumumab/bortezomib/melphalan/prednisone [D-VMP]) and bortezomib/lenalidomide/dexamethasone (VRd) had the highest probabilities of being more effective than Rd continuous for PFS (HR: D-Rd, 0.53; D-VMP, 0.57, VRd, 0.77) and OS (HR: D-Rd, 0.68; VRd, 0.77, D-VMP, 0.78). D-Rd had the highest chance of being ranked as the most effective treatment with respect to PFS and OS. Results using a smaller network focusing on only those regimens that are relevant in Europe were consistent with the primary analysis. Conclusions: These comparative effectiveness data may help inform treatment selection in TIE patients with NDMM

    Quantum Rabi oscillations in coherent and in mesoscopic "cat" field states

    Get PDF
    International audienceThe simple resonant Rabi oscillation of a two-level system in a single-mode coherent field reveals complex features at the mesoscopic scale, with oscillation collapses and revivals. Using slow circular Rydberg atoms interacting with a superconducting microwave cavity, we explore this phenomenon in an unprecedented range of interaction times and photon numbers. We demonstrate the efficient production of 'cat' states, quantum superposition of coherent components with nearly opposite phases and sizes in the range of few tens of photons. We measure cuts of their Wigner functions revealing their quantum coherence and observe their fast decoherence. This experiment opens promising perspectives for the rapid generation and manipulation of non-classical states in cavity and circuit Quantum Electrodynamics

    Cognitive differentiation during childhood: A study on cognitive profiles of 5, 7, and 9-year-old children

    No seio do debate sobre se a inteligĂȘncia Ă© mais bem definida por um fator geral ou por aptidĂ”es especĂ­ficas, ganha relevĂąncia a hipĂłtese da diferenciação cognitiva. AnĂĄlises recentes enfatizam o interesse dessa questĂŁo para a investigação e alertam para a relevĂąncia das suas implicaçÔes na ĂĄrea educativa. Este estudo analisou a possibilidade de a diferenciação das aptidĂ”es cognitivas ocorrer jĂĄ na infĂąncia e tambĂ©m o efeito moderador do Quociente de InteligĂȘncia na magnitude da relação entre as habilidades cognitivas. Aplicou-se uma bateria de provas que avaliam vĂĄrias funçÔes cognitivas a uma amostra de 231 crianças com 5, 7 e 9 anos, distribuĂ­das por trĂȘs grupos de desempenho cognitivo. Os resultados de uma anĂĄlise de clusters hierĂĄrquica e de uma anĂĄlise de variĂąncia apontam para a nĂŁo diferenciação das funçÔes cognitivas na infĂąncia. Contudo, uma anĂĄlise mais cuidadosa aponta para alguma diferenciação suportada pela heterogeneidade dos perfis cognitivos junto dos alunos com Quociente de InteligĂȘncia elevado.Within the debate about whether intelligence is best defined by a general factor or specific skills, the hypothesis of cognitive differentiation gains relevance. Recent analyses have emphasized the importance of this issue in the investigation of cognitive skills and have highlighted its implications in education. This study examined the possibility that the differentiation of cognitive abilities may occur during childhood and investigated the moderating effect of Intelligence Quotient on the magnitude of the relationship between cognitive abilities. A battery of tests for assessing cognitive function was administered to 231 children aged 5, 7, and 9 years old, who were divided into three cognitive performance groups. The results of hierarchical cluster analysis and variance analysis indicate the lack of differentiation of cognitive functions during childhood. However, a more careful analysis suggests some differentiation supported by the heterogeneity of cognitive profiles among students with high Intelligence Quotient.FCT -Fundação para a CiĂȘncia e a Tecnologia(SFRH/BD/84153/2012

    Isatuximab plus carfilzomib and dexamethasone versus carfilzomib and dexamethasone in elderly patients with relapsed multiple myeloma: IKEMA subgroup analysis

    In this subgroup analysis of the randomized, Phase 3 IKEMA study (NCT03275285), we evaluated efficacy and safety of the anti-CD38 monoclonal antibody isatuximab (Isa) in combination with carfilzomib-dexamethasone (Isa-Kd) versus Kd in older (≄70 years of age, n = 86) and younger (<70 years, n = 216) patients with relapsed multiple myeloma (MM). Patients received Isa 10 mg/kg intravenously weekly for 4 weeks, then every 2 weeks in the Isa-Kd arm, and approved schedule of carfilzomib (twice weekly) and dexamethasone in both study arms. Primary endpoint was progression-free survival (PFS); key secondary efficacy endpoints included rates of overall response (ORR), very good partial response or better (≄VGPR), minimal residual disease negativity (MRD–), and complete response (CR). Addition of Isa to Kd resulted in improved PFS in elderly patients (hazard ratio, 0.36 [95% CI, 0.18–0.75]) consistent with the significant PFS improvement observed in the overall IKEMA population. Treatment with Isa-Kd improved depth of response versus Kd, with higher rates of ≄VGPR (73.1% vs. 55.9%), MRD– (23.1% vs. 11.8%), and CR (38.5% vs. 23.5%). Although the incidence of grade ≄3 treatment-emergent adverse events (TEAEs) was higher in Isa-Kd, the incidence of serious TEAEs was similar between arms. Fewer elderly patients definitively discontinued treatment due to TEAEs in Isa-Kd than Kd: 11.8% versus 23.5%. In conclusion, Isa-Kd provides a consistent benefit versus Kd in elderly patients, with a manageable safety profile, and represents a new treatment option for patients with relapsed MM, independent of age
