Evolution of a novel adrenal cell type that promotes parental care.

Cell types with specialized functions fundamentally regulate animal behaviour, and yet the genetic mechanisms that underlie the emergence of novel cell types and their consequences for behaviour are not well understood1. Here we show that the monogamous oldfield mouse (Peromyscus polionotus) has recently evolved a novel cell type in the adrenal gland that expresses the enzyme AKR1C18, which converts progesterone into 20α-hydroxyprogesterone. We then demonstrate that 20α-hydroxyprogesterone is more abundant in oldfield mice, where it induces monogamous-typical parental behaviours, than in the closely related promiscuous deer mice (Peromyscus maniculatus). Using quantitative trait locus mapping in a cross between these species, we ultimately find interspecific genetic variation that drives expression of the nuclear protein GADD45A and the glycoprotein tenascin N, which contribute to the emergence and function of this cell type in oldfield mice. Our results provide an example by which the recent evolution of a new cell type in a gland outside the brain contributes to the evolution of social behaviour.

Father's Absence in the Mongolian gerbil (Meriones unguiculatus) is associated with alterations in paternal behavior, T, cort, presence of ERα, and AR in mPOA/ BNST.

Testosterone (T), estrogen receptor alpha (ERα), and androgen receptor (AR) play a significant role in the regulation of paternal behavior. We determined the effects of deprivation of paternal care on alterations in paternal behavior, T concentrations in plasma, and the presence of ERα and AR in the medial preoptic area (mPOA), bed nucleus of the stria terminalis (BNST), medial amygdala (MeA), and olfactory bulb (OB), as well as the corticosterone (CORT) concentrations in plasma caused by deprivation of paternal care in the Mongolian gerbil (Meriones unguiculatus). Twenty pairs of gerbils were formed; the pups were deprived of paternal care (DPC) in 10 pairs. In another 10 pairs, the pups received paternal care (PC). Ten males raised in DPC condition and 10 males raised in PC conditions were mated with virgin females. When they became fathers, each DPC male and PC male was subjected to tests of paternal behavior on day three postpartum. Blood samples were obtained to quantify T and CORT concentrations, and the brains were removed for ERα and AR immunohistochemistry analyses. DPC males gave less care to their pups than PC males, and they had significantly lower T concentrations and levels of ERα and AR in the mPOA and BNST than PC males. DPC males also had higher CORT concentrations than PC males. These results suggest that in the Mongolian gerbil father's absence causes a decrease in paternal care in the offspring, which is associated with alterations in the neuroendocrine mechanisms that regulate it.

Práticas psicológicas nos Creas do interior do RS: o olhar de trabalhadoras(es) / Psychological practices on CREAS in the countryside of the state of Rio Grande do Sul: perspectives of workers / Prácticas psicológicas en CREAS en el interior de Rio Grande do Sul: perspectiva de trabajadoras/es

O presente texto tem o objetivo de explanar ações desempenhadas por psicólogas(os) trabalhadoras(es) dos Centros de Referência Especializados de Assistência Social (Creas), em situações de violência intrafamiliar, identificadas a partir do estude empírico realizado por mim, psicóloga pesquisadora, também trabalhadora de um Creas. Participaram da pesquisa doze psicólogas(os), trabalhadoras(es) destes centros, em sete municípios do interior do Rio Grande do Sul, onde foram realizadas, presencialmente, as entrevistas. A análise dos dados apontou para uma compreensão metodológica a partir de três dimensões já apontadas na bibliografia, sendo elas: a) Acolhida Inicial, que demonstra que esses profissionais geralmente iniciam suas práticas com uma família ou indivíduo indo ao encontro destes, buscando a vinculação dos mesmos com o serviço; b) Acompanhamento Especializado, onde essas(es) trabalhadoras(es) desenvolvem suas práticas com diversidade e criatividade, a partir de visitas domiciliares, trabalhos com grupos, indivíduos ou famílias, geralmente em conjunto com outros profissionais, principalmente assistentes sociais; c) Articulação com a Rede, onde se identificou um importante movimento para o trabalho em conjunto com outros serviços disponíveis no território. Por fim, as considerações finais indicam que ainda há um caminho a ser trilhado com relação à definição das práticas dos psicólogos no Creas. Porém, há muito que se falar a respeito de práticas que já estão ocorrendo. Assim, tornam-se relevantes as pesquisas acadêmicas nesse contexto, pois ao inserir os profissionais psicólogos trabalhadores da política, eles podem promover uma articulação entre a produção do fazer cotidiano e a reflexão teórica e acadêmica sustentada pelas pesquisas.(AU)

This study aims to explore the activities developed by psychologists from the Centros de Referência de Atenção Especializada (CREAS - Brazilian Specialized Social Assistance Reference Centers), regarding situations of intrafamily violence identified by me, the author, a research psychologist and, CREAS worker. Participants include 12 psychologists who work on such centers from 7 cities in the countryside of Rio Grande do Sul, Brazil, where the interviews were conducted in person. The data analysis pointed toward a methodological comprehension based on 3 dimensions that have already been mentioned in the literature: the Initial Approach, which shows that these workers usually initiate their practices with a family or an individual by going after them, seeking bond development with the service. The Specialized Follow-up, in which these workers develop their practices with diversity and creativity, through home visits and activities with group, family or individual, often with other workers, such as social assistance workers. And the Network Articulation, in which a significant movement toward working with the public services available on each territory is identified. Finally, there is still a path to be taken regarding the definition of psychological practices on CREAS, however, there is much to be noticed of what has already been occurring. Thus, academic research on such context is relevant since the inclusion of psychologists who work in this policy may promote an articulation between daily activity and the theoretical and academic reflection, supported by the research.(AU)

Este texto tuvo por objetivo explicar las acciones desarrolladas por psicólogas/os trabajadoras/es en los "Centros de Referência Especializados de Assistência Social" (CREAS) (Centros de Referencia Especializados en Asistencia Social), respecto a las situaciones de violencia intrafamiliar, identificadas por un estudio empírico hecho por una psicóloga-investigadora que actúa en un CREAS. Participaron 12 psicólogas/os que trabajan en estos centros, en siete ciudades del interior de Rio Grande do Sul (Brasil), donde se llevó a cabo las entrevistas en persona. El análisis de datos apuntó a una comprensión metodológica de tres dimensiones ya destacadas en la bibliografía: la Acogida Inicial, que enseña que estos profesionales generalmente empiezan sus prácticas con una familia o individuo buscando el encuentro para la promoción de la vinculación con el servicio; El Seguimiento Especializado, en el que desarrollan sus prácticas con diversidad y creatividad desde visitas domiciliarias, trabajos con grupos, individuos o familias, generalmente junto a otros profesionales, sobre todo con trabajadores sociales; y Articulación con la Red de Servicios, en la cual se identificó un importante movimiento para el trabajo con otros servicios disponibles en el territorio. Por fin, se observa que todavía hay un camino por recorrer en relación a la definición de las prácticas de psicólogos en CREAS, aunque hay mucho que decir respecto a las prácticas que ya están ocurriendo. Así, se vuelven relevantes las investigaciones académicas en ese contexto por introducir a los profesionales psicólogos trabajadores de la política, las cuales pueden promover una articulación entre la producción del hacer cotidiano y la reflexión teórica y académica sustentada por las investigaciones.(AU)

Implicações da prática profissional no acolhimento institucional de crianças: perspectiva de cuidadoras / Implications of professional practice in children's institutional sheltering: caregivers' perspective / Implicaciones de la práctica profesional en el alojamiento institucional de niños: perspectiva de cuidadoras

Este estudo qualitativo teve como objetivo compreender, a partir da teoria de bioecológica de desenvolvimento, as implicações da prática profissional no processo de acolhimento de crianças em uma casa-abrigo, na perspectiva de cuidadoras. As participantes foram 10 profissionais de uma casa-abrigo localizada na região sul do Brasil. Utilizou-se a entrevista semiestruturada e a organização e análise dos dados sustentou-se na Grounded Theory, com auxílio do software Atlas.ti 8.4.14. Os resultados evidenciaram uma centralização das ações de acolhimento e atenção em torno dos cuidados físicos das crianças. As ações para promover suporte e cuidados emocionais dentro da casa-abrigo eram delegadas às profissionais da equipe técnica da instituição. Observou-se que as dificuldades encontradas pelas cuidadoras diziam respeito à falta de segurança e preparação para responder e acolher as demandas emocionais das crianças, as quais estão presentes em diversos momentos do processo de acolhimento. Percebeu-se que as práticas institucionais afetaram decisivamente tanto as ações de acolhimento das participantes e o suporte emocional oferecido às crianças na passagem pela casa-abrigo quanto as cuidadoras, no sentido de vivenciarem no trabalho sentimentos de insegurança. Os resultados tensionam ecologicamente a interação nos processos proximais presentes no desenvolvimento humano. Advoga-se pela reflexão sobre as implicações das práticas institucionais de uma casa-abrigo e o desenvolvimento infantil, visando o cuidado integral dos acolhidos.(AU)

Based on the developmental bioecological theory, this study analyzes the implications of professional practice in children's user embracement at a shelter from the caregivers' perspective. Semi-structured interviews were conducted with 10 professionals from a shelter located in southern Brazil. Data organization and analysis was performed based on Grounded Theory using the Atlas.ti 8.4.14 software. Results showed that embracement and attention focus on the physical care of children. Support and emotional care activities were delegated to the institution's technical team. Caregivers faced difficulties regarding the lack of security and preparation to respond to and accept the children's emotional demands, which arise at different moments in the embracement process. The institutional practices decisively affected both user embracement actions and the emotional support offered to the children, as well as the caregivers, in the sense of experiencing feelings of insecurity. These findings ecologically tension the interaction in the proximal processes present in human development. Further reflections on the implications of institutional shelter-based practices for child development are needed to provide comprehensive care.(AU)

Este estudio cualitativo tuvo como objetivo comprender, desde la perspectiva de la teoría bioecológica del desarrollo, las implicaciones de la práctica profesional en el proceso de acogida de niños en una institución infantil desde la perspectiva de las cuidadoras. Las participantes fueron 10 profesionales de una institución de acogida infantil ubicada en la región Sur de Brasil. Se utilizó la entrevista semiestructurada, y para la organización y análisis de datos se aplicó Grounded Theory, con el uso del software Atlas.ti 8.4.14. Los resultados mostraron que las acciones de recepción y atención se centran en el cuidado físico de los niños. Las acciones de promoción de apoyo y cuidado emocional dentro del alojamiento se asignaron a los profesionales del equipo técnico de la institución. Se observó que las dificultades encontradas por las cuidadoras estaban relacionadas con la falta de seguridad y preparación para responder y aceptar las demandas emocionales de los niños, las cuales se encuentran presentes en diferentes momentos del proceso de acogida. Se notó que las prácticas institucionales afectaron decisivamente tanto las acciones de acogida de las participantes como el apoyo emocional que la institución brinda a los niños durante su paso, así como a las cuidadoras en el sentido de experimentar sentimientos de inseguridad en el trabajo. Estos resultados tensan ecológicamente la interacción en los procesos proximales presentes en el desarrollo humano. Se aboga por reflexionar sobre las implicaciones de las prácticas institucionales en los alojamientos institucionales y el desarrollo infantil, apuntando a la atención integral de los acogidos.(AU)

Relatos da pandemia: ser mulher e mãe em tempos de covid-19 / Pandemic reports: being a woman and mother in covid-19 times / Relatos de la pandemia: ser mujer y madre en tiempos del covid-19

Partindo da pergunta "Como tem sido ser mulher e mãe em tempos de pandemia?", o presente estudo convidou mulheres que são mães, em redes sociais virtuais, a partilhar um relato de suas experiências com a readaptação parental em função do distanciamento social causado pela pandemia de covid-19. O objetivo foi refletir sobre a experiência de ser mulher e mãe em tempos de covid-19 e distanciamento social, apontando algumas ressonâncias do cenário pandêmico na subjetividade dessas mulheres. O estudo teve como base o referencial psicanalítico, tanto na construção da pesquisa e análise dos relatos quanto na sua discussão. A análise dos cerca de 340 relatos coletados, os quais variaram de uma breve frase a longos parágrafos, apontou para uma série de questionamentos, pontos de análise e reflexões. A pandemia, e o decorrente distanciamento social, parece ter colocado uma lente de aumento sobre as angústias das mulheres que são mães, evidenciando sentimentos e sofrimentos sempre presentes. Destacaram-se, nos relatos, a sobrecarga das mulheres com as tarefas de cuidado dos filhos e da casa, a culpa, a solidão, a exaustão, e o sentimento de que não havia espaço nesse contexto para "ser mulher", sendo isso entendido especialmente a questões estéticas e de vaidade.(AU)

Starting from the question "How does it feel to be a woman and a mother in pandemic times?", this study invited women who are mothers, in virtual social networks, to share their experiences regarding parental adaptations due to social distancing caused by the COVID-19 pandemic. The objective was to reflect on the experience of being a woman and a mother in the context of COVID-19 and of social distancing, pointing out some resonances of the pandemic scenario in the subjectivity of these women. The study was based on the psychoanalytical framework, both in the construction of the research and analysis of the reports and in their discussion. The analysis of about 340 collected reports, which ranged from a brief sentence to long paragraphs, pointed to a series of questions, analysis topics, and reflections. The pandemic, and the resulting social distancing, seems to have placed a magnifying glass over the anguish of women who are mothers, showing ever-present feelings and suffering. The reports highlighted women's overload with child and house care tasks, the guilt, loneliness, exhaustion, and the feeling that there was no space in this context to "be a woman," and it extends to aesthetic and vanity related questions especially.(AU)

A partir de la pregunta "¿cómo te sientes siendo mujer y madre en tiempos de pandemia?", este estudio invitó por las redes sociales a mujeres que son madres a compartir un relato de sus experiencias sobre la readaptación parental en función del distanciamiento social causado por la pandemia del covid-19. Su objetivo fue reflexionar sobre la experiencia de ser mujer y madre en tiempos del covid-19 y el distanciamiento social, señalando algunas resonancias del escenario pandémico en la subjetividad de estas mujeres. Este estudio se basó en el marco psicoanalítico, tanto en la construcción de la investigación y análisis de los informes como en su discusión. El análisis de los casi 340 relatos, que variaron de una pequeña frase a largos párrafos, generó en las investigadoras una serie de cuestionamientos y reflexiones. La pandemia y el consecuente distanciamiento social parece haber agrandado las angustias de las mujeres que son madres, evidenciando sentimientos y sufrimientos siempre presentes. En los relatos destacan la sobrecarga de las mujeres con las tareas de cuidado de los hijos y del hogar, la culpa, la soledad, el cansancio, así como el sentimiento de que no hay espacio em este contexto para "ser mujer", relacionado principalmente a cuestiones estéticas y de vanidad.(AU)

O inventário de envolvimento paterno revisado: inclusão de pais com filhos pré-escolares / The inventory of father involvement revised: inclusion of fathers with preschool children / El inventario de envolvimiento paterno revisado: inclusión de padres de preescolares

Apesar da importância do envolvimento paterno, sua avaliação persiste desafiadora. No Brasil, o Inventário de Envolvimento Paterno (IFI-BR) vem se mostrando adequado para uso com pais de crianças de 5 a 10 anos. Entretanto, do ponto de vista do desenvolvimento infantil e de intervenções preventivas, seria importante avaliar o envolvimento paterno quando as crianças são mais novas. Assim, este trabalho teve como objetivos: identificar limitações do IFI-BR, quando usado com pais de crianças entre 2 e 10 anos, e avaliar itens para o IFI-BR-revisado. No Estudo 1, 434 pais com filhos no Ensino Infantil ou Fundamental 1 responderam a um questionário sociodemográfico e ao IFI-BR. Com base em análises de dados omissos, estrutura interna e precisão, modificações foram sugeridas, visando à manutenção da estrutura interna original do instrumento. No Estudo 2, 572 pais com filhos na mesma faixa etária responderam a um questionário sociodemográfico e à versão modificada do IFI-BR. Foram comparadas as frequências de dados omissos e estimativas de precisão para os itens originais e modificados, selecionando aqueles que melhor representavam essa amostra de pais para compor a versão revisada do IFI-BR. Esses resultados indicaram evidências adequadas de validade, com base no conteúdo da versão revisada do IFI-BR, quando utilizada para avaliar a qualidade do envolvimento paterno de pais brasileiros com filhos do Ensino Infantil ao Fundamental 1. Após verificadas evidências de validade adicionais, essa versão revisada do IFI-BR poderá ser utilizada, por exemplo, em estudos longitudinais e na avaliação de intervenções precoces com pais.(AU)

Despite the importance assigned to father involvement, evaluating this construct remains a challenge. In Brazil, the Inventário de Envolvimento Paterno (IFI-BR) has showed satisfactory evidence of validity for fathers of children between 5 and 10 years old. From the perspective of child development and preventive interventions, however, evaluating father involvement with younger children is essential. Hence, this study sought to: identify limitations of the IFI-BR for fathers of children between 2 and 10 years old, and evaluate items for a revised IFI-BR. In Study 1, 434 fathers of children in early childhood and primary school settings answered a sociodemographic questionnaire and the IFI-BR. Based on analyses of missing data, internal structure, and reliability, modifications were suggested to maintain the original internal structure. In Study 2, 572 fathers of children in the same age range answered a sociodemographic questionnaire and the modified IFI-BR. After comparison between values for missing data and reliability of the original and modified items, the items that best represented the broader sample of fathers were selected to compose the revised IFI-BR. Results indicated adequate evidence of content validity for the revised IFI-BR when used to assess the involvement of Brazilian fathers with children in early childhood education and primary school settings. After additional evidence has been verified, this revised IFI-BR can be used, for example, in longitudinal studies and to evaluate early interventions with fathers.(AU)

La participación paterna es importante, pero su evaluación sigue siendo desafiadora. En Brasil, el Inventário de Envolvimento Paterno (IFI-BR) demuestra ser adecuado para aplicar a padres de niños de 5 a 10 años de edad. No obstante, desde la perspectiva del desarrollo infantil y de las intervenciones preventivas, sería importante evaluar la participación de los padres de niños más jóvenes. Este estudio tuvo como objetivos: identificar limitaciones del IFI-BR cuando se aplica a padres de niños entre los 2 y 10 años y evaluar ítems para el IFI-BR-revisado. En Estudio 1, 434 padres con hijos en el jardín de infantes o escuela primaria respondieron un cuestionario sociodemográfico y el IFI-BR. Con base en el análisis de datos faltantes, estructura interna y exactitud, se sugirieron modificaciones para mantener la estructura interna original del instrumento. En Estudio 2, 572 padres respondieron un cuestionario sociodemográfico y la versión modificada del IFI-BR. Se compararon las frecuencias de datos faltantes y estimaciones de exactitud para los ítems originales y modificados, seleccionando aquellos que representaban mejor a esta muestra de padres para la versión revisada del IFI-BR. Estos resultados indicaron evidencia adecuada de validez, basada en el contenido de la versión revisada del IFI-BR, cuando se utilizó para evaluar la calidad de la participación de padres brasileños con niños en el jardín de infantes y en la escuela primaria. Después de verificada la evidencia adicional de validez, la versión revisada del IFI-BR se puede utilizar, por ejemplo, en estudios longitudinales y en la evaluación de intervenciones precoz con los padres.(AU)

Falsa acusação de abuso sexual na alienação parental: luto ou melancolia? / False accusation of sexual abuse in parental alienation: mourning or melancholia? / Falsa acusación de abuso sexual en la alienación parental: ¿luto o melancolía?

Este artigo apresenta como principal objeto de estudo a falsa acusação de abuso sexual no contexto da alienação parental para, diante dela, estabelecer a seguinte problemática: será possível propor uma eventual correlação entre si e os processos psíquicos do luto e da melancolia? Neste sentido, a partir do recurso teórico ao referencial psicanalítico de Freud e de Laplanche, debate as circunstâncias que norteiam o discurso levado ao Judiciário pelo genitor alienante valorizando em tal movimento não apenas a realidade material da prova, tão importante no campo jurídico, mas também a realidade psíquica ditada pelo inconsciente, a qual se pauta em uma noção de verdade que, na sua vinculação direta com a particularidade de cada sujeito e com o dinamismo das relações específicas que ele estabelece consigo mesmo e com os outros, coloca em xeque as certezas positivistas da norma. Em termos conclusivos, destaca o quanto, a despeito da atual literatura existente sobre alienação parental no Brasil a correlacionar, em regra, a um luto mal elaborado por parte do alienante, é possível e mesmo desejável cogitar também a presença da melancolia - ou, mais especificamente, de traços melancólicos intermediários - na formação e desenvolvimento desse fenômeno.(AU)

This article presents as the main object of study the false accusation of sexual abuse in the context of parental alienation, to establish the following problem: would it be possible to propose a probable correlation between parental alienation and the psychic processes of mourning and melancholia? In this sense, based on the psychoanalytic theoretical framework of Freud and Laplanche, the article discusses the circumstances that guide the discourse taken to the judiciary branch by the alienating parent, valuing in such action not only the material reality of the evidence, which is very important in the legal field, but also the psychic reality dictated by the unconscious, which is guided by a notion of truth that, in its direct connection with the particularity of each subject and with the dynamism of the specific relations that they establish with themselves and others, threatens the positivist certainties of the norm. In conclusive terms, it highlights how, despite the current existing literature on parental alienation in Brazil generally correlates it to a poorly elaborated mourning by the alienating person, it is possible and even desirable to also consider the presence of melancholia-or, more specifically, of intermediate melancholic traits-in the formation and development of this phenomenon.(AU)

Este artículo presenta como principal objeto de estudio la falsa acusación de abuso sexual en el contexto de alienación parental, con el fin de responder al siguiente planteamiento: ¿Es posible proponer una posible correlación entre la alienación parental y los procesos psíquicos de duelo y melancolía? Para ello, desde el marco psicoanalítico de Freud y de Laplanche, se discuten las circunstancias del discurso llevado al Poder Judicial por el padre alienante, que valora en tal movimiento no solo la realidad material de la prueba, tan importante en el campo jurídico, sino también la realidad psíquica dictada por el inconsciente, el cual se guía por una noción de verdad que, en su conexión directa con la particularidad de cada sujeto y con el dinamismo de las relaciones específicas que establece consigo mismo y con otros, pone en jaque las certezas positivistas de la norma. En la conclusión, destaca cómo, a pesar de la literatura actual existente sobre la alienación parental en Brasil, en general, la correlaciona con un duelo mal diseñado por parte de la persona alienante, es posible e incluso deseable considerar la presencia de la melancolía -más específicamente, de rasgos melancólicos intermediarios- en la formación y desarrollo de este fenómeno.(AU)

Inventory of Father Involvement and Fathers' Perceptions of Family Life / Inventário de Envolvimento Paterno e Percepções dos Pais sobre a Vida Familiar / Inventario de Participación Paterna y Percepciones de los Padres sobre la Vida Familiar

Cross-cultural comparisons of father involvement and related issues are still scarce, as are consolidated measures for its assessment. We examined relationships among father involvement and family-related variables, in Brazil, and then compared these results with findings from other countries. In total, 200 fathers with children aged 5 to 10 completed the Brazilian version of the Inventory of Father Involvement (IFI-BR), and measures of stress, marital satisfaction, parent-child relationship, children's social skills and their behavior problems. Correlations among these variables were between .32 and .58, providing new evidence of validity for the IFI-BR. When comparing Brazilian results with correlations observed in other countries, the majority did not differ in magnitude, indicating that father involvement systematically influences the fathers' well-being, family relationships, and their children's socioemotional development, in different countries. In addition to the psychometric evidence for the IFI-BR, these results also indicate the potential for using the IFI in different cultures. (AU)

Comparações transculturais do envolvimento paterno e questões relacionadas ainda são escassas, como são medidas consolidadas para sua avaliação. Examinou-se relações entre o envolvimento paterno e variáveis relacionadas à família, no Brasil, e comparou-se esses resultados com os de outros países. No total, 200 pais com filhos de 5 a 10 anos completaram a versão brasileira do Inventory of Father Involvement (IFI-BR), medidas de estresse, satisfação conjugal, relacionamento pai-filho, habilidades sociais das crianças e seus problemas de comportamento. Correlações entre essas variáveis variaram de 0,32 a 0,58, fornecendo novas evidências de validade para o IFI-BR. Comparando os resultados brasileiros com correlações de outros países, a maioria não diferiu em magnitude, indicando que o envolvimento paterno influencia sistematicamente o bem-estar paterno, as relações familiares e o desenvolvimento socioemocional infantil, em diferentes países. Além das evidências psicométricas para o IFI-BR, esses resultados também indicam o potencial de uso do IFI em diferentes culturas. (AU)

Las comparaciones transculturales de la participación del padre y temas relacionados aún son escasas, al igual que las medidas consolidadas para su evaluación. Examinamos las relaciones entre la participación del padre y las variables relacionadas con la familia en Brasil y comparamos estos resultados con los de otros países. En total, 200 padres de niños de 5 a 10 años completaron la versión brasileña del Inventory of Father Involvement (IFI-BR), medidas de estrés, satisfacción conyugal, relación padre-hijo, habilidades sociales de los niños y problemas de comportamiento infantil. Las correlaciones entre estas variables oscilaron entre .32 y .58, proporcionando nueva evidencia de validez para el IFI-BR. Al comparar los resultados brasileños con las correlaciones de otros países, la mayoría no difería en magnitud, lo que indica que la participación paterna influye sistemáticamente en el bienestar paterno, las relaciones familiares y el desarrollo socioemocional infantil en diferentes países. Además de la evidencia psicométrica do IFI-BR, estos resultados también indican el potencial de usar el IFI en diferentes culturas. (AU)

Estudio piloto: contacto padre-hijo(a) y oxitocina en varones preparados especialmente para el nacimiento / Pilot study: father-child contact and oxytocin in males with a special education for childbirth

INTRODUCCÍON: Los padres se han involucrado cada vez más en el embarazo y el nacimiento de sus hijos, pero aún se requieren intervenciones paternas que permitan reubicar al padre en su rol de corresponsabilidad en la crianza. OBJETIVO: Observar el comportamiento-actitud paterna hacia el/la hijo(a) y la cantidad de oxitocina (OT) secretada en el nacimiento, en padres preparados de un modo especial para el parto. Método: Estudio piloto de 8 meses, parte de una investigación mayor cuali-cuantitativa de dos fases. La fase cualitativa inicial desarrolló una intervención preparatoria de padres para el nacimiento, con énfasis en la vinculación padre-hijo(a). La fase cuantitativa correspondió al piloto de la intervención paterna antenatal. RESULTADOS: Los padres presenciaron activamente el momento del expulsivo y el encuentro madre-hijo(a). Posteriormente, todos optaron por el contacto físico piel-piel con su hijo(a). La OT paterna experimentó un aumento (no significativo) durante el contacto padre-hijo(a) en comparación con la OT basal (momento inmediato al nacimiento). CONCLUSIONES: Padres preparados, sensibilizados y vinculados con su hijo(a) desde el embarazo experimentarían variaciones de la cantidad de OT cuando realizan contacto piel-piel con su hijo(a) en el nacimiento. Se requiere investigación experimental con una muestra mayor de participantes para concluir de manera categórica.

INTRODUCTION: Fathers have been increasingly involved in the pregnancy and birth of their children, but paternal interventions are still required to relocate the father in his role of co-responsibility in parenting. OBJECTIVE: To observe the paternal behavior-attitude towards the child and the amount of oxytocin (OT) secreted at birth in parents prepared (in a special way) for childbirth. METHOD: Pilot study of 8 months, part of a larger qualitative-quantitative research of two phases. The initial qualitative phase developed a male preparatory intervention for the birth, with emphasis on the father-child bonding. The quantitative phase corresponded to the pilot of the antenatal paternal intervention. RESULTS: Fathers actively witnessed the moment of delivery and the mother-child attachment. Subsequently, all of them opted for physical skin-to-skin contact with their child. Paternal OT experienced a (non-significant) increase during father-child contact, compared to baseline OT (immediately after birth). CONCLUSIONS: Males prepared, sensitized and involved with their child since pregnancy would experience variations in the amount of OT when they make father-child skin-to-skin contact at childbirth. Experimental research with a larger sample of participants is required to categorically reach a conclusion.

Motivational increase of androgens and behavior by infant distress calls in highly responsive common marmoset fathers, Callithrix jacchus.

Common marmoset fathers are highly involved in care of their infants. However, variability exists in their response to infant behavior even in paternally experienced fathers. Using infant distress cries as a motivation test, we investigated: 1. the differences in paternally experienced fathers' motivation to search for the infant vocalization stimuli; 2. the relationship between a father's motivation to search for the source of the infant cries and testosterone levels; and 3. if there is a rapid steroidogenesis pathway leading to increased testosterone and estradiol in the peripheral circulation. Only 44% of the paternally experienced fathers showed a high frequency of searching for the source of the infant distress cries. Through the use of multisteroid analysis, we found high responsive fathers had significantly higher levels of progesterone and testosterone in response to infant distress cries compared to a control stimulus with progesterone and androstenedione correlating with testosterone, while no differences were seen in low responders. The frequency to search for the infant stimuli was positively correlated with higher testosterone compared to control vocal levels. These results suggest that searching for the source of infant cries represents a motivation behavior for fathers that is activated by testosterone and reflects rapid circulating testosterone.

Pregnancy Risk Assessment Monitoring System for Dads: A piloted randomized trial of public health surveillance of recent fathers' behaviors before and after infant birth.

BACKGROUND: Becoming a father impacts men's health and wellbeing, while also contributing to the health and wellbeing of mothers and children. There is no large-scale, public health surveillance system aimed at understanding the health and behaviors of men transitioning into fatherhood. The purpose of this study was to describe piloted randomized approaches of a state-based surveillance system examining paternal behaviors before and after their infant's birth to better understand the health needs of men and their families during the transition to parenthood. METHODS: During October 2018-July 2019, 857 fathers in Georgia were sampled 2-6 months after their infant's birth from birth certificates files and surveyed via mail, online or telephone, in English or Spanish, using two randomized approaches: Indirect-to-Dads and Direct-to-Dads. Survey topics included mental and physical health, healthcare, substance use, and contraceptive use. FINDINGS: Weighted response rates (Indirect-to-Dads, 33%; Direct-to-Dads, 31%) and population demographics did not differ by approach. Respondents completed the survey by mail (58%), online (28%) or telephone (14%). Among 266 fathers completing the survey, 55% had a primary care physician, and 49% attended a healthcare visit for themselves during their infant's mother's pregnancy or since their infant's birth. Most fathers were overweight or had obesity (70%) while fewer reported smoking cigarettes (19%), binge drinking (13%) or depressive symptoms (10%) since their infant's birth. CONCLUSIONS: This study tests a novel approach for obtaining population-based estimates of fathers' perinatal health behaviors, with comparable response rates from two pragmatic approaches. The pilot study results quantify a number of public health needs related to fathers' health and healthcare access.

Uncovering the Sex-Specific Endocrine Responses to Reproduction and Parental Care.

Hormones mediate physiological and behavioral changes in adults as they transition into reproduction. In this study, we characterize the circulating levels of five key hormones involved in reproduction in rock doves (Columba livia): corticosterone, progesterone, estradiol, testosterone, and prolactin using univariate and multivariate approaches. We show similar patterns as previous studies in the overall patterns in circulating levels of these hormones, i.e., testosterone (males) and estradiol (females) high during nest-building or egg-laying, prolactin increasing at mid-incubation and peaking at hatching (both sexes), and elevated corticosterone levels in later incubation and early nestling development. In our investigation of hormone co-variation, we find a strong correlation between prolactin and corticosterone across sampling stages and similarities in earlier (early to mid-incubation) compared to later (late incubation to nestling d9) sampling stages in males and females. Finally, we utilized experimental manipulations to simulate nest loss or altered caregiving lengths to test whether external cues, internal timing, or a combination of these factors contributed most to hormone variation. Following nest loss, we found that both males and females responded to the external cue. Males generally responded quickly following nest loss by increasing circulating testosterone, but this response was muted when nest loss occurred early in reproduction. Similar treatment type, e.g., removal of eggs, clustered similarly in hormone space. These results suggest internal drivers limited male response early in reproduction to nest loss. In contrast, circulating levels of these hormones in females either did not change or decreased following nest manipulation suggesting responsiveness to external drivers, but unlike males, this result suggests that reproductive processes were decreasing.

Relative Importance of Determinants of Changes in Eating Behavior during the Transition to Parenthood: Priorities for Future Research and Interventions.

BACKGROUND: Healthy eating behavior throughout pregnancy and postpartum is important. This study aimed to investigate the perceived sex-specific importance of determinants of changes in eating behavior during pregnancy and postpartum. METHODS: Fifty-four determinants were rated by first-time parents (n = 179) on their impact. Experts (n = 31) rated the determinants in terms of their modifiability, relationship strength, and population-level effect from which a "priority for research"-score was calculated. RESULTS: During pregnancy, the three highest rated determinants by women were "health concerns", "physiological changes", and "fatigue". Men perceived "health concerns", "health consciousness", and "influence of the pregnant partner" as important. Postpartum, the three highest rated determinants by women were "adaptation to rhythm of baby", "baby becomes priority", and "practical constraints because of the baby". Men perceived "adaptation to rhythm of baby", "fatigue". and "(lack of) anticipation" as important. According to the experts, "professional influence", "food knowledge", and "home food availability" received high priority scores for both sexes and during both periods. CONCLUSIONS: Priority for research and interventions should go towards tailored family-based approaches focusing on food education in a broad sense taking into account aspects such as health consciousness, self-efficacy skills, and the social and home food environment while being supported by healthcare professionals.

Paternal and infanticidal behavior in the Mongolian gerbil (Meriones unguiculatus): An approach to neuroendocrine regulation.

This study aimed to provide evidence on estrogen and androgen pathways regulating the Mongolian gerbil's paternal and infanticidal behaviors (Meriones unguiculatus). We analyzed estrogen receptor alpha (ERα) and androgen receptor (AR) distribution in the medial preoptic area (mPOA), the bed nucleus of stria terminalis (BNST), as well as the anterior hypothalamic nucleus (AHN), the ventromedial hypothalamus nucleus (VMH), and the periaqueductal gray area (PAG) nuclei activated when males interact paternally or aggressively with the pups, respectively. Twenty aggressive males towards the pups and 10 paternal were selected through a screen paternal behavior test. Three groups of 10 males each were formed: paternal males (PAT), males with testosterone (T)-induced paternal behavior (T-PAT), and aggressive males (AGG). Male gerbils could interact with a pup for a few minutes, and their brains were removed and dissected for ERα and AR immunoreactivity (ir). The results showed that in T-PAT and PAT males, the number of ERα-ir and AR-ir cells in the mPOA/BNST was significantly higher than in AGG males. In AGG males, the number of ERα-ir and AR-ir cells in the AHN/VMH/PAG was significantly higher than PAT and T-PAT males. This difference in the presence of ERα and AR in nuclei activated in paternal interactions in the Mongolian gerbil supports the idea that these receptors participate in regulating paternal behavior. Also, these results suggest, for the first time, that they could be involved in the infanticidal behavior in this rodent.

Paternal High-Fat Diet Exposure Induces Adverse Effects on Offspring Health: a Systematic Review of Animal Studies

Abstract This systematic review examined the effects of paternal exposure to a high-fat diet on the likelihood of offspring developing health consequences, including metabolic conditions. While the connection between a mother's diet and offspring health has been well established, our understanding of whether offspring health is affected by a father's diet remains limited. This systematic review was performed according to the Preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA) recommendations. The PubMed, Scopus, and Embase electronic databases were searched using combinations of the MESH terms: obesogenic diet, high-fat diet, cafeteria diet, paternal diet, parental diet, programming, paternal effects, and paternal programming. Sixteen studies were selected after assessing articles for eligibility criteria. The main outcomes concerning offspring health related to metabolic disorders. The offspring of fathers exposed to a high-fat diet displayed elevated gene expression and serum levels of leptin, decreased gene expression and serum levels of adiponectin, insulin resistance, glucose intolerance, hyperglycemia, hyperinsulinemia, changes in the transcriptome of pancreatic islet tissues, increased triglycerides, and increased expression of lipogenic genes. The available evidence suggests that paternal exposure to a high-fat diet may induce harmful effects on the health of offspring.

Formas de (des)engajamento: aborto entre homens adultos no Rio de Janeiro, Brasil / Formas de (des) compromiso: aborto entre hombres adultos en Rio de Janeiro, Brasil / Forms of (dis)engagement: abortion among adult men in Rio de Janeiro, Brazil

Resumo O artigo analisa dimensões sociológicas que intervêm no processo decisório para o aborto a partir de uma pesquisa antropológica sobre trajetórias afetivo-sexual, contraceptiva e reprodutiva de mulheres e homens, de diferentes classes sociais e gerações, no Rio de Janeiro, Brasil. Neste texto, explora-se as narrativas presentes em 15 entrevistas em profundidade com homens de 40-49 anos sobre a gravidez e o aborto voluntário das parceiras. Salientamos dois argumentos: 1) a centralidade do gênero e da inserção de classe na determinação dos comportamentos masculinos em relação ao aborto; 2) a externalidade masculina ao evento como traço estruturante de gênero, em distintas gerações. Produzir inflexões analíticas para compreensão dos modos relacionais que engendram decisões reprodutivas no âmbito da conjugalidade ou fora dela lança luz sobre as muitas dificuldades que cercam o abortamento em geral e o papel masculino nesse tensionado cenário.

Abstract This paper analyses sociological dimensions influencing the abortion decision-making process, drawing on a larger anthropological study of the affective-sexual, contraceptive and reproductive trajectories of women and men, of different social classes and generations in Rio de Janeiro, Brazil. We explore 15 in-depth interviews with men aged 40-49 about their partners' pregnancy and voluntary abortion. Two arguments are discussed: (1) the crucial role of gender and class position in determining male behaviors with regard to abortion by a partner; 2) men´s externality in relation to the event as a gender-structuring trait in different generations. Producing analytical reflections to understand how relational ways influence reproductive decisions in the context of conjugality or outside it sheds light on many difficulties that surround abortion in general and the male role in this tensioned scenario.

Preconceptional Maternal Vegetable Intake and Paternal Smoking Are Associated with Pre-implantation Embryo Quality.

Inadequate nutrition and lifestyle behaviors, particularly during the periconception period, are associated with a negative impact on embryonic and subsequent fetal development. We investigated the associations between parental nutritional and lifestyle factors and pre-implantation embryo development. A total of 113 women and 41 partners, with a corresponding 490 embryos, who underwent intracytoplasmic sperm injection (ICSI) treatment subscribed to the mHealth coaching platform "Smarter Pregnancy." At baseline, nutrition and lifestyle behaviors (intake of fruits, vegetables, folic acid, and smoking and alcohol use) were identified and risk scores were calculated. A lower risk score represents healthier behavior. As outcome measure, a time-lapse morphokinetic selection algorithm (KIDScore) was used to rank pre-implantation embryo quality on a scale from 1 (poor) to 5 (good) after being cultured in the Embryoscope™ time-lapse incubator until embryonic day 3. To study the association between the nutritional and lifestyle risk scores and the KIDScore in men and women, we used a proportional odds model. In women, the dietary risk score (DRS), a combination of the risk score of fruits, vegetables, and folic acid, was negatively associated with the KIDScore (OR 0.86 (95% CI 0.76 to 0.98), p = 0.02). This could mainly be attributed to an inadequate vegetable intake (OR 0.76 (95% CI 0.59 to 0.96), p = 0.02). In men, smoking was negatively associated with the KIDscore (OR 0.53 (95% CI 0.33 to 0.85), p < 0.01). We conclude that inadequate periconceptional maternal vegetable intake and paternal smoking significantly reduce the implantation potential of embryos after ICSI treatment. Identifying modifiable lifestyle risk factors can contribute to directed, personalized, and individual recommendations that can potentially increase the chance of a healthy pregnancy.

Association between preconception paternal smoking and birth defects in offspring: evidence from the database of the National Free Preconception Health Examination Project in China.

OBJECTIVE: To clarify whether preconception paternal smoking has any adverse effects on the offspring. DESIGN: Prospective, population-based study. SETTING: Preconception registry data from the National Free Preconception Health Examination Project. POPULATION OR SAMPLE: Couples planning pregnancy, with complete information on preconception paternal smoking behaviour and pregnancy outcomes. METHODS: The effect of questionnaire-based paternal smoking behaviour during preconception and pregnancy was assessed via logistic regression. Additionally, we performed a 1:1 case-control (birth defects versus normal pregnancy) analysis, matched for maternal province, folic acid supplementation and paternal alcohol consumption. MAIN OUTCOME MEASURES: Risk of birth defects in offspring. RESULTS: In total, 566 439 couples with complete information on preconception paternal smoking behaviour and pregnancy outcomes were enrolled. The preconception paternal smoking rate was 28.7% (162 482) overall: 8.7% (49 303) stopped smoking, 13.3% (75 517) decreased their smoking, and 6.6% (37 662) continued smoking during early pregnancy. The risk of birth defects was higher in the continued-smoking (P < .000, odds ratio [OR] 1.87, 95% CI 1.36-2.56) and decreased-smoking groups (P = .007, OR 1.41, 95% CI 1.10-1.82). In the case-control analysis, infants whose fathers stopped (P = .003, OR 0.32, 95% CI 0.15-0.67) or decreased smoking (P = .000, OR 0.25, 95% CI 0.13-0.49) were at lower risk of congenital heart diseases, limb abnormalities, digestive tract anomalies and neural tube defects than those whose fathers continued smoking. CONCLUSION: Preconception paternal smoking may be associated with congenital heart diseases, limb abnormalities and neural tube defects in the offspring. Changes in smoking behaviour may reduce this risk. TWEETABLE ABSTRACT: This study suggests that preconception paternal smoking is associated with birth defects in offspring. Changes in smoking behaviour may reduce this risk.

Prefrontal cortex is associated with the rapid onset of parental behavior in inexperienced adult mice (C57BL/6).

There is significant variability in the immediate behavioral response displayed by inexperienced adult mice when exposed to pups for the first time. The aim of this study was to determine which brain regions were engaged (higher c-Fos-immunoreactivity, c-Fos-ir) when virgin females, that were exposed to pups for 15 or 60 min, displayed full parental behavior (FPB), partial parental behavior (PPB), or non-parental behavior (NPB), or virgin males displayed PPB or infanticidal behavior (IB). The number of c-Fos-ir neurons in the prelimbic cortex (PL) was higher in parental females than in the NPB group (after a 15-min exposure), and the group not exposed to pups (NE). C-Fos expression in the nucleus accumbens (NA) was increased in most groups of females exposed to pups compared to NE. Higher c-Fos-ir was also found in the shell subregion of the NA in infanticidal males, compared to males NE. The cortical (CoA) and medial (MA) amygdala also showed higher c-Fos-ir in parental females compared to NE animals. However, PPB and IB male groups also exhibited higher c-Fos-ir in the CoA and MA compared to the NE group. The expression of c-Fos in the different subregions of medial preoptic area and the ventromedial nucleus of the hypothalamus was not specifically associated with either parental or infanticidal behavior. No brain activation in males was specifically associated with infanticidal behavior. Our results suggest that 15 min of exposure to pups is enough to detect brain regions associated with parental behavior (PL) or pups processing (NA, MA, CoA) in mice. The PL might participate in the immediate onset of parental behavior in virgin females, coordinating and planning its rapid execution.
