Search for Wγ resonances in proton-proton collisions at s=13 TeV using hadronic decays of Lorentz-boosted W bosons

A search for Wγ resonances in the mass range between 0.7 and 6.0 TeV is presented. The W boson is reconstructed via its hadronic decays, with the final-state products forming a single large-radius jet, owing to a high Lorentz boost of the W boson. The search is based on proton-proton collision data at s=13 TeV, corresponding to an integrated luminosity of 137 fb−1, collected with the CMS detector at the LHC in 2016–2018. The Wγ mass spectrum is parameterized with a smoothly falling background function and examined for the presence of resonance-like signals. No significant excess above the predicted background is observed. Model-specific upper limits at 95% confidence level on the product of the cross section and branching fraction to the Wγ channel are set. Limits for narrow resonances and for resonances with an intrinsic width equal to 5% of their mass, for spin-0 and spin-1 hypotheses, range between 0.17 fb at 6.0 TeV and 55 fb at 0.7 TeV. These are the most restrictive limits to date on the existence of such resonances over a large range of probed masses. In specific heavy scalar (vector) triplet benchmark models, narrow resonances with masses between 0.75 (1.15) and 1.40 (1.36) TeV are excluded for a range of model parameters. Model-independent limits on the product of the cross section, signal acceptance, and branching fraction to the Wγ channel are set for minimum Wγ mass thresholds between 1.5 and 8.0 TeV

Instituto Nacional de Saúde da Mulher da Criança e do Adolescente Fernandes Figueira. Rio de Janeiro, RJ, Brasil.A transição epidemiológica das últimas décadas no Brasil trouxe necessidade de adaptações para o cuidado de crianças e adolescentes. Essa Nova Pediatria tem a violência, as condições crônicas e complexas e a saúde mental como importantes questões em sua agenda, com destaque para o comportamento suicida pelo impacto clínico-epidemiológico e pelo tabu que representa, inclusive na formação pediátrica. O objeto da pesquisa foi a relação dialógica dos médicos residentes (MR) em pediatria com o comportamento suicida, assim como a participação dos programas de residência médica (PRM) neste processo. Partiu-se de uma hipótese de que exista uma desconsideração ou inabilidade teórica e clínica dos MR por essa temática, dificultando a assistência integral ao público infantojuvenil. Objetivou-se compreender a percepção e o conhecimento de MR em pediatria sobre a morte e o comportamento suicida na infância e na adolescência, valorizando as experiências e vivências construídas nos PRM, a influência da cultura incluindo a mídia e as novas demandas da especialidade. Foi utilizado o método qualitativo, por meio da técnica de Grupos Focais (GF), a partir da qual 44 MR de cinco PRM no Rio de Janeiro participaram da pesquisa. Os diálogos evocados nos cinco GF realizados, gravados e transcritos, foram analisados, junto aos registros não verbais, a partir de três unidades de sentido elencadas e correlacionadas: O tabu do suicídio; Peculiaridades da assistência pediátrica: idealizações e conflitos; Lacunas formativas dos PRM em pediatria. Foi proposto o conceito de triplo tabu como uma tentativa de compreensão do suicídio de crianças e adolescentes pelos profissionais. Diante da constatação dos vazios curriculares sobre comportamento suicida na formação pediátrica, cinco pontos tornaram-se relevantes: (1) a baixa exposição sobre o tema; (2) o desinteresse discente; (3) o desconforto provocado pelo tema; (4) a organização dos PRM; (5) o ímpeto anatomopatológico. Como contrapartida ética, foi realizada uma atividade acadêmica subsequente para os integrantes de cada PRM envolvido. As proposições dos participantes e dos pesquisadores configuraram o objetivo estratégico da pesquisa, constituindo-se como uma potencial contribuição para a implantação e a consolidação de um novo currículo nacional para os PRM em pediatria, em vigor a partir de 2019.The epidemiological transition of the last decades in Brazil brought the need to implemente several adaptations for the care of children and adolescents. This new pediatrics shows important topics on its content as violence, chronic and complex conditions and mental health, with emphasis on suicidal behavior due to clinical end epidemiological impact and the taboo that it represents, including in pediatric education. The objective of the research was to understand the relationship between medical residents (MR) in pediatrics with suicidal behavior, as well as the responsability of medical residency programs in this process. The hypothesis was that there is a lack of consideration or inability of MR for this issue, making it difficult to provide comprehensive assistance to children and adolescents. The qualitative method was choosen, using the Focal Groups technique (GF), from which 44 MR of five medical residency training in Rio de Janeiro participated in the research. The dialogues of the five groups, recorded and transcribed, were analyzed, together with the nonverbal registers. Three categories correlated appeared: The suicide taboo; Peculiarities of pediatric care: idealizations and conflicts; Formative gaps of medical residency training in pediatrics. The researchers proposed the concept of a triple taboo as an attempt to understand the suicide of children and adolescents by pediatrics´ professionals. Faced with these curriculum´s gaps pediatric education, five points became relevant: (1) the low exposure on the theme; (2) student disinterest; (3) the discomfort caused by the theme; (4) the organization of medical residency training; (5) the anatomopathological impetus. As an ethical counterpart, a subsequent academic activity was carried out for the members of each group involved. The participants' and researchers' proposals configured the strategic aim of the investigation, constituting a potential contribution to the implementation and consolidation of a new national curriculum for the medical residency training in pediatrics, beginning from 2019

Attachment, suicidal behavior, and self-harm in childhood and adolescence: a study of a cohort of Brazilian schoolchildren

Abstract Background Attachment influences the development and the formation of the self and subjectivity and, just as early adverse events, may be related to the occurrence of mental disorders, suicidal behavior, and self-harm throughout life. This study aimed to analyze the effect of mental representation of attachment in children on suicidal behavior and self-harm throughout childhood and adolescence, considering the mediating role of internalizing problems. Methods Based on a cohort of 500 students (mean age 8 years, SD 1.2) sampled from public schools in a Brazilian southeastern metropolis, 316 children were followed for eight years in three waves (2006, 2008, 2012). The following data from the research baseline (2005) were used: family drawing, maternal and family variables, and sociodemographic data. The mental representation of attachment (independent variable) was measured by the Family Drawing Global Scale, discriminating between secure attachment and non-secure attachment. Suicidal behavior/self-harm (dependent variable) and internalizing problems were evaluated in three research waves through CBCL and YSR (ASEBA). Descriptive analysis, calculation of frequencies and p-values of the variables of interest, as well as modeling of structural equations, were performed. Results The prevalence throughout the study was: 17.1% [CI 13.3–20.8] for suicidal ideation and 8.9% [CI 5.6 – 12.2] for self-harm; there was a recurrence at one time in 16.5% [IC 12.6 – 20.3] and in two or more moments in 4.1% [CI 2.0 – 6.3] of the sample. Female gender (p = 0.035), internalizing disorders (p < 0.01), and non-secure attachment (p = 0.035) were associated with the occurrence of suicidal behavior/self-harm. The modeling indicated that 92,2% of the total effect of attachment (p = 0.069) on suicidal behavior/self-harm was due to direct effect, the other 7,8% of the effect being mediated by internalizing problems, adjusted for the confounding variables sex, skin color/race, and social stratum. The total effect showed a positive value, which indicates an increase in suicidal behavior/self-harm when the non-secure attachment is present. The approximate OR of non-secure attachment on the total effect (direct + indirect) was 1.15, indicating that, when adjusting for confounding variables, there was a 15% increase in suicidal behavior/self-injury from non-secure attachment. Conclusions The study supports the hypothesis that there is a relationship between disruptive attachment patterns (non-secure attachment) developed during infancy and suicidal and self-harm behavior during childhood and adolescence. These findings validate the concern about the first thousand days of childhood as a critical period for child growth and development, but also for the mental health of children and adolescents
