Aging to 24 months increased C57BL/6J mouse social sniffing and hippocampal Neto1 levels, and impaired female spatial learning.

Understanding how natural aging impacts rodent performance in translational behavior tests is critical to teasing apart impairments due to age-related decline from neurodegenerative disorder modeling. Reduced neuropilin and tolloid-like 1 (NETO1), an accessory protein of ionotropic glutamate receptors involved in synaptic plasticity, was associated with Alzheimer's disease, yet aging effects on Neto1 remain unclear. For these reasons, our goal was to characterize how Neto1 expression corresponded with social, repetitive, and spatial learning behaviors and stress response across the C57BL/6J mouse lifespan. We measured social preferences in three-chamber tests, and motor stereotypies by marble burying. Cognitive flexibility is typically assessed in the Morris water maze (MWM), wherein C57BL/6J mice exhibit deficits with age. However, fatigue or locomotor impairment may confound interpretation of MWM performance. Therefore, we used a less arduous water T-maze (WTM) to compare spatial learning flexibility in 2, 9-15, and 24-month-old male and female mice to test the hypothesis that deficits would emerge with age. In both sexes, 9-15-month-olds made more chamber entries during social preference tests, while 2-month-olds did less social sniffing than aged mice. No age or sex differences emerged in marble burying or serum corticosterone measurements. In 24-month-olds hippocampal Neto1was increased relative to 2-month-olds, and male cognitive flexibility was strong, while spatial learning and reversal learning of 24-month-old females was impaired in WTM irrespective of Neto1 expression. The WTM is a useful alternative assessment for cognitive flexibility deficits in aged mice, and the role of hippocampal Neto1 in promoting social sniffing is of interest.

Mapeamento do uso da caderneta de saúde da criança por pais e profissionais: um estudo descritivo / Mapping the use of the child health handbook by parents and professionals: a descriptive study / Mapeo del uso del manual de salud infantil por padres y profesionales: un estudio descriptivo

Objetivo: Identificar o conhecimento dos pais acerca da Caderneta de Saúde da Criança, mapear o preenchimento da Caderneta pelos profissionais e correlacionar o preenchimento da caderneta com a orientação dos pais pelos profissionais de saúde. Métodos: pesquisa quantitativa descritiva, realizada num hospital universitário, através da aplicação de formulário com 22 pais ou responsáveis e análise através de tabelas, gráficos, estatística descritiva e inferencial. Resultados: (77,3%) dos entrevistados alegaram não ter recebido orientação sobre a Caderneta, a maioria das cadernetas não apresentava registro no item de Índice de Massa Corporal tanto como a maioria apresentava preenchimento completo no item de registro de vacinas do calendário básico e as correlações não foram significativas, apresentando independência na maioria. Conclusão: evidenciou-se uma necessidade de orientação dos familiares tanto como capacitação dos profissionais que trabalham com a população infantil e não se verificou dependência entre a maioria das variáveis correlacionadas neste estudo

Objective:To identify parents' knowledge about the Child Health Handbook, map the completion of the booklet by professionals and correlate the completion of the booklet with the guidance of parents by health professionals. Methods: descriptive quantitative research, conducted in a university hospital, through the application of a form with 22 parents or guardians and analysis through tables, graphs, descriptive and inferential statistics. Results: (77.3%) of respondents claimed not to receive guidance on the Passbook, the majority of the handbooks had no record in the Body Mass Index item as much as most completed in the basic calendar vaccine record item and correlations were not significant, presenting independence in the majority. Conclusion: there was a need for guidance from family members as well as training of professionals working with the child population and there was no dependence between most of the correlated variables in this study

Objetivo: Identificar el conocimiento de los padres sobre el Manual de Salud Infantil, mapear la finalización del folleto por profesionales y correlacionar la finalización del folleto con la orientación de los padres por parte de profesionales de la salud. Métodos: investigación cuantitativa descriptiva, realizada en un hospital universitario, mediante la aplicación de un formulario con 22 padres o tutores y análisis a través de tablas, gráficos, estadísticas descriptivas e inferenciales. Resultados: El (77.3%) de los encuestados afirmaron no haber recibido orientación sobre el Manual, la mayoría de los manuales no tenían registros en el ítem del Índice de Masa Corporal tanto como la mayoría había completado en el ítem y las correlaciones del registro básico de la vacuna del calendario no fueron significativas, presentando independencia en la mayoría. Conclusión: era necesaria la orientación de los miembros de la familia, así como la capacitación de profesionales que trabajan con la población infantil y no hubo dependencia entre la mayoría de las variables correlacionadas en este estudio
