RESUMO

Abstract Background: Working memory-based spatial cognition has attracted the attention of the scientific community in navigation and reorientation projects. The dominant approach considers that spontaneous spatial navigation behavior is based merely on environmental geometry (built and natural environmental objects). In this domain, DCD (Developmental Coordination Disorder) motor skill orientation problems have been frequently associated with poor visuospatial cognition, while immersive VR environments encourage more repetition, allowing for faster motor skill development and recovery. Objective: This pilot study tested the functionality of an immersive VR environment with environmental geometry (rectangular arena rich in symmetry) and featural landmark cues (striped wall, flora) as a route-learning tool for children with motor skill disorders. Methods: Forty DCD children aged 5 to 8 years (20 boys and 20 girls); five (5) 3D reality modeling setups with orthogonality, symmetry, and striped walls as design parameters; and trial walk-through coordination exercises using a predefined visual pathway with different motor control conditions (daylight, darkness). Participants' path completion rate, path completion time, and walk-through satisfaction were recorded as route-learning performance variables and analyzed statistically. Results/findings: DCD children's spatial orientation was statistically shown to be more stable and robust (in path completion rates, termination time, and walk-through level of satisfaction) in a virtual 3D environment rich in orthogonality, symmetry, and featural cues as landmarks. In this compound environmental geometry setup, training functionality and immersive learning performance enjoyed an 8.16% better path completion rate, a 12.37% reduction in path completion time, and 32.10% more walk-through satisfaction than reality modeling setups poor in geometry and landmarks. The effectiveness and robustness were validated statistically. Conclusion: Children with motor skill difficulties train and learn better in virtual 3D environments that are rich in orthogonality, symmetry, and featural landmark cues.

Resumen Antecedentes: La cognición espacial basada en la memoria de trabajo ha atraído la atención de la comunidad científica en proyectos de navegación y reorientación. El enfoque dominante considera que el comportamiento espontáneo de navegación espacial se basa meramente en la geometría ambiental (objetos ambientales construidos y naturales). En este ámbito, los problemas de orientación de las habilidades motoras del TDC (Trastorno del Desarrollo de la Coordinación) se han asociado con frecuencia a una cognición visoespacial deficiente, mientras que los entornos de RV (Realidad Virtual) inmersivos fomentan una mayor repetición, lo que permite un desarrollo y una recuperación más rápidos de las habilidades motoras. Objetivo: Este estudio piloto probó la funcionalidad de un entorno de RV inmersiva con geometría ambiental (arena rectangular rica en simetría) y señales de puntos de referencia característicos (pared rayada, flora) como herramienta de aprendizaje de rutas para niños con trastornos de la habilidad motora. Métodos: Cuarenta niños con TDC de entre 5 y 8 años (20 niños y 20 niñas); cinco (5) configuraciones de modelado de realidad 3D con ortogonalidad, simetría y paredes rayadas como parámetros de diseño; y ejercicios de coordinación de recorrido de prueba utilizando una ruta visual predefinida con diferentes condiciones de control motor (luz diurna, oscuridad). Se registraron la tasa de finalización del recorrido, el tiempo de finalización del recorrido y el grado de satisfacción de los participantes como variables de rendimiento del aprendizaje de recorridos y se analizaron estadísticamente. Resultados: Se demostró estadísticamente que la orientación espacial de los niños con TDC era más estable y robusta (en tasas de finalización del camino, tiempo de finalización y nivel de satisfacción del recorrido) en un entorno 3D virtual rico en ortogonalidad, simetría y señales de características como puntos de referencia. En esta configuración de geometría ambiental compuesta, la funcionalidad del entrenamiento y el rendimiento del aprendizaje inmersivo disfrutaron de un 8,16% más de tasa de finalización de ruta, una reducción del 12,37% en el tiempo de finalización de ruta y un 32,10% más de satisfacción de recorrido que las configuraciones de modelado de realidad pobres en geometría y puntos de referencia. La eficacia y la solidez se validaron estadísticamente. Conclusiones: Los niños con dificultades motrices entrenan y aprenden mejor en entornos virtuales 3D ricos en ortogonalidad, simetría y puntos de referencia característicos.

RESUMO

Humans are exposed every day to innumerable external stimuli, both environmental and microbial. Immunological memory recalls each specific stimulus and mounts a secondary response that is faster and of a larger magnitude than the primary response; this process constitutes the basis for vaccine development. The COVID-19 pandemic offers a unique opportunity to study the development of immune memory against an emergent microorganism. Memory T cells have an important role in the resolution of COVID-19, and they are key pillars of immunological memory. In this review, we summarize the main findings regarding anti-SARS-CoV-2 memory T cells after infection, after vaccination, and after the combination of these two events ("hybrid immunity"), and analyze how these cells can contribute to long-term protection against the infection with SARS-CoV-2 variants.

Los humanos se exponen cada día a innumerables estímulos externos, tanto ambientales como microbianos. La memoria inmunológica registra de manera específica un estímulo y articula una respuesta secundaria más rápida y de mayor magnitud que la respuesta primaria; este proceso constituye la base del desarrollo de vacunas. La pandemia de COVID-19 ofreció la oportunidad de estudiar el desarrollo de la memoria inmunológica contra un microorganismo emergente. Las células T de memoria tienen un papel importante en la resolución de COVID-19 y son pilares importantes de la memoria inmunológica. En esta revisión se resumen los principales hallazgos de la respuesta de las células T de memoria contra la infección por SARS-CoV-2, a la vacunación o a la combinación de ambos procesos ("inmunidad híbrida"), y se discute cómo estas células pueden contribuir a la protección a largo plazo contra distintas variantes del virus.

RESUMO

Resumen Objetivo: Determinar el efecto de la formación en ajedrez sobre las funciones ejecutivas: planificación, flexibilidad cognitiva, memoria de trabajo e inhibición por medio de la revisión de la literatura científica de investigaciones en la última década. Método: Se desarrolló una búsqueda en las bases de datos Web of Science, Scielo, Pubmed, Scopus y en Google académico, para el período 2012-2022, mediante la metodología de revisión sistemática. Resultados: Se encontraron sesenta y seis artículos y solo se analizaron trece que cumplieron con los criterios de inclusión. Fue posible identificar relaciones del ajedrez con las cuatro funciones ejecutivas: inhibición, flexibilidad, memoria de trabajo y planificación, además del funcionamiento ejecutivo en general. Discusión: Los resultados han sugerido que la práctica sistemática del ajedrez contribuye al desarrollo del funcionamiento ejecutivo. Por ser una práctica de fácil alcance, se podría aprovechar sus beneficios incorporándola en diversos escenarios educativos. Conclusión: La mayoría de las investigaciones de los últimos diez años provee evidencia que permite demostrar la hipótesis de que la práctica del ajedrez se asocia un mejor desempeño ejecutivo; también se encontró un único artículo que por el contrario rechaza esta relación.

Abstract Objective: Determine the effect of chess training on executive functions: planning, cognitive flexibility, working memory and inhibition by reviewing the scientific research literature in the last decade. Method: A search was carried out in the Web of Science, Scielo, Pubmed, Scopus and Google Scholar databases for the period 2012-2022, using the systematic review methodology. Results: Sixty-six articles were found and only thirteen that met the inclusion criteria were analyzed. It was possible to identify relationships between chess and the four executive functions: inhibition, flexibility, working memory and planning, in addition to executive functioning in general. Discussion: The results have suggested that the systematic practice of chess contributes to the development of executive functioning. Because it is an easily accessible practice, its benefits could be taken advantage of by incorporating it into various educational scenarios. Conclusion: The majority of research from the last ten years provides evidence that allows us to demonstrate the hypothesis that chess practice is associated with better executive performance; there is also a single article that, on the contrary, rejects this relationship.

RESUMO

Resumen Actualmente, los rescatistas y el personal de emergencias que asiste a la comunidad en situaciones de desastre no cuentan con un tratamiento adecuado que proteja su salud mental. Las técnicas más ampliamente utilizadas como el debriefing y el defusing resultarían inefectivas para tal fin, e incluso perjudiciales a largo plazo. En el presente estudio se llevaron adelante dos cuasiexperimentos con 42 rescatistas bolivianos y 39 peruanos, para probar los efectos de la aplicación grupal de la técnica de Procesamiento Asistido en Situaciones Estresantes Recientes (PASER) en la reducción de los niveles de reactividad ansiosa vinculados al recuerdo de labores de rescate. Se utilizó el inventario de Autopercepción del Estado Emocional (APEEM), para evaluar la intensidad del recuerdo. Los resultados indicaron que la asistencia externa a la memoria de trabajo a través de la aplicación de la técnica PASER redujo significativamente la autopercepción de los niveles de perturbación emocional asociados al recuerdo en rescatistas peruanos t(38) = 6.642; p < .0001 y bolivianos t(24)=7.452; p < .0001. Estas primeras observaciones indican que la técnica PASER, aplicada de forma temprana y grupal a rescatistas y personal de emergencias, resultaría adecuada para la prevención de trastornos de ansiedad y estrés derivados de las tareas tensionantes de sus labores. La reducción temprana de esta sintomatología evitaría los frecuentes problemas de comorbilidad que conllevan los síntomas de ansiedad no tratados. Resultan necesarios nuevos estudios longitudinales para verificar la eficacia de esta intervención a largo plazo.

Abstract Currently, rescuers and emergency personnel who assist the community in disaster situations do not have adequate treatment to protect their mental health. The most widely used techniques such as debriefing and defusing would be ineffective and even harmful in the long term. In the present study, two quasi-experiments were conducted with 42 Bolivian and 39 Peruvian rescuers to test the effects of group application of the Assisted Processing in Recent Stressful Situations (PASER, for its Spanish acronym) technique on the reduction of levels of anxious reactivity associated with the memory of rescue tasks. The Self-Perception of Emotional State Inventory (APEEM, for its Spanish acronym) was used to assess the intensity of recall. Results indicated that external support of working memory through the application of the PASER technique significantly reduced self-perceived levels of emotional disturbance associated with recall in both Peruvian t(38) = 6.642; p < .0001 and Bolivian rescue workers t(24) = 7.452; p < .0001. These initial observations suggest that the PASER technique, applied early and in groups to rescuers and emergency personnel, would be appropriate for the prevention of anxiety and stress disorders resulting from the stressful tasks of their work. Early reduction of this symptomatology would avoid the frequent comorbidity problems associated with untreated anxiety symptoms. Further longitudinal studies are needed to verify the long-term effectiveness of this intervention.

RESUMO

Resumen El desarrollo de la lectura es un proceso acumulativo en el que progresivamente los niños se vuelven más eficaces y comienzan a enfrentar textos más extensos y complejos. Conocer los factores cognitivos y afectivos que inciden sobre el desempeño en la comprensión lectora tiene gran relevancia. Por ello, el objetivo de este estudio fue analizar la capacidad explicativa de la tolerancia al distrés en la comprensión lectora de textos narrativos y expositivos, considerando conjuntamente el rol de la memoria de trabajo en niños y niñas de 9 a 12 años. Se evaluaron 211 niños que cursaban cuarto a sexto año de educación primaria (117 niñas, 94 niños; edad M = 10.94, DE = 0.87 años). Se utilizó un diseño no experimental, transversal y correlacional. La TD se evaluó mediante el Indicador Comportamental de Resiliencia al Distrés, la memoria de trabajo con una tarea de amplitud compleja de dígitos, mientras que la comprensión lectora de texto narrativo y expositivo con una prueba de screening apropiada a la edad. Los resultados muestran que, al ser consideradas conjuntamente, la memoria de trabajo contribuye al desempeño en comprensión lectora tanto de textos narrativos como expositivos, mientras que la tolerancia al distrés no realiza un aporte significativo. El estudio aporta al conocimiento de factores que contribuyen al desempeño en comprensión lectora en niños y niñas de edad escolar, mostrando que la habilidad para tolerar estados emocionales negativos no aporta significativamente a la comprensión de distintos tipos de texto, cuando se considera además la capacidad de almacenar y procesar simultáneamente información.

Abstract Reading development is a cumulative process in which children progressively become more efficient and begin to deal with longer and more complex texts. Knowing the cognitive and affective factors that affect reading comprehension performance is of great relevance. Therefore, this study aimed to analyze the explanatory capacity of distress tolerance in reading comprehension of narrative and expository texts, jointly considering the role of working memory in 9 to 12-year-old children. A total of 211 children who were in the fourth to sixth year of primary education were evaluated (117 girls, 94 boys; M age = 10.94, SD = 0.87 years). A non-experimental, cross-sectional, correlational design was used. Distress tolerance was assessed using the Behavioral Indicator of Resilience to Distress, working memory with a complex digit span task, while CL of narrative and expository text with an age-appropriate screening test. The results show that, when considered jointly, working memory contributes to reading comprehension performance of both narrative and expository texts, while distress tolerance does not make a significant contribution. The study contributes to the knowledge of factors that contribute to reading comprehension performance in school-age children, showing that the ability to tolerate negative emotional states does not contribute significantly to comprehension of different types of text when the ability to simultaneously maintain and process information is considered.

RESUMO

Introduction: Introduction: changes in cognitive performance and memory of older adults (OA) can interfere in their reporting their diet. Objective: to evaluate the impact of memory bias in dietary estimation between OA and their primary caregivers (PC) through the food frequency questionnaire (FFQ) for Mexican OA and weighed food records (WFR). Methods: the present analysis uses the estimated dietary information based on the response provided by 51 older adults (OA) and their primary caregivers (PC) from the validation study of the FFQ for Mexicans OA was conducted during lockdowns for COVID-19. The personnel who applied FFQ and WFR were trained with standardized instruments and procedures. The Wilcoxon test was used to compare the intake per day of the foods and food groups, the Spearman correlation coefficient was used to evaluate the grams of intake per day of the food groups, and kappa coefficient was used to compare the level of food items and food groups between OA and PC. Results: in 11 of 14 food groups, no significant differences were observed between the amounts of intake reported by OA and PC. In the groups of dairy products, fruits, vegetables, and legumes, moderate agreement was observed (κ = 0.63 to 0.79), and in the rest of the groups was strong to perfect (κ ≥ 0.80). Correlation of the amount of intake between OA and PC was high in all food groups (r ≥ 0.87). Conclusion: the high correlation and high agreement between the amounts and frequencies of the food groups consumed as reported by the older adults and primary caregivers indicate that the information from both respondents is reliable.

Introducción: Introducción: los cambios cognitivos y la memoria que presentan los adultos mayores (AM) pueden interferir al momento de reportar los alimentos de su dieta. Objetivo: evaluar el impacto del sesgo de memoria en la estimación de la dieta entre AM y sus cuidadores principales (CP) a través del cuestionario de frecuencia de alimentos (CFA) para AM mexicanos y el registro de peso de alimentos (RPA). Métodos: el presente análisis utiliza la información dietética estimada con base en la respuesta proporcionada por 51 adultos mayores (AM) y sus cuidadores principales (CP) del estudio de validación del CFA para AM mexicanos que se realizó durante el confinamiento por COVID-19. El personal que aplicó CFA y RPA fue capacitado con instrumentos y procedimientos estandarizados. Se utilizó prueba de Wilcoxon para comparar la ingesta por día de los alimentos y grupos de alimentos, el coeficiente de correlación de Spearman para evaluar los gramos de ingesta por día de los grupos de alimentos y el coeficiente kappa para comparar el nivel de alimentos y grupos de alimentos entre AM y CP. Resultados: en 11 de 14 grupos de alimentos no se observaron diferencias significativas entre las cantidades de ingesta reportadas por AM y CP. En los grupos de lácteos, frutas, verduras y legumbres se observó concordancia moderada (κ = 0,63 a 0,79), y en el resto de los grupos fue de fuerte a perfecta (κ ≥ 0,80). La correlación de la cantidad de ingesta entre AM y CP fue alta en todos los grupos de alimentos (r ≥ 0,87). Conclusión: La alta correlación y la alta concordancia entre las cantidades y frecuencias de los grupos de alimentos consumidos según lo informado por los adultos mayores y los cuidadores principales indican que la información de ambos encuestados es confiable.

RESUMO

SUMMARY: We evaluated the role and mechanism of acteoside in the regulation of memory impairment induced by chronic unpredictable mild stress (CUMS). CUMS was used to induce depression in rats and the successful establishment of CUMS model were verified by forced swimming test and sucrose preference test. The Y-maze test and novel object recognition test assessed memory functions. The structural changes in the cortex and hippocampus were observed by hematoxylin and eosin (HE) staining. Immunofluorescence staining and western blotting determined the protein levels. Y-maze test and novel object recognition test showed that there was memory performance impairment in rats of CUMS group, which was improved by the acteoside treatment. HE staining showed that CUMS exposure damaged the structure in the cortex and hippocampus, while the acteoside treatment alleviated the structural changes. Compared with the control group, the levels of BNDF and CREB in the cortex and hippocampus of the CUMS group were significantly decreased. Acteoside significantly reversed the expressions of these proteins in CUMS rats. Meanwhile, compared with the control group, the levels of p-mTOR and p- P70S6K in the cortex and hippocampus of the CUMS group were significantly increased, and these changes were significantly reversed by acteoside. Nevertheless, the effect of acteoside on mTOR signaling was markedly blocked by rapamycin, a specific inhibitor of mTOR signaling. Acteoside can attenuate memory impairment and ameliorate neuronal damage and synaptic plasticity in depression rats probably via inhibiting the mTOR signaling pathway. Acteoside may serve as a novel reagent for the prevention of depression.

Evaluamos el papel y el mecanismo del acteoside en la regulación del deterioro de la memoria inducido por estrés leve crónico impredecible (ELCI). Se utilizó ELCI para inducir depresión en ratas y el establecimiento exitoso del modelo ELCI se verificó mediante una prueba de natación forzada y una prueba de preferencia de sacarosa. La prueba del laberinto en Y y la prueba de reconocimiento de objetos novedosos evaluaron las funciones de la memoria. Los cambios estructurales en la corteza y el hipocampo se observaron mediante tinción con hematoxilina y eosina (HE). La tinción por inmunofluorescencia y la transferencia Western determinaron los niveles de proteína. La prueba del laberinto en Y y la prueba de reconocimiento de objetos novedosos mostraron que había un deterioro del rendimiento de la memoria en ratas del grupo ELCI, que mejoró con el tratamiento con acteósidos. La tinción con HE mostró que la exposición a ELCI dañó la estructura de la corteza y el hipocampo, mientras que el tratamiento con actósidos alivió los cambios estructurales. En comparación con el grupo de control, los niveles de BNDF y CREB en la corteza y el hipocampo del grupo ELCI disminuyeron significativamente. Acteoside revirtió significativamente las expresiones de estas proteínas en ratas ELCI. Mientras tanto, en comparación con el grupo control, los niveles de p-mTOR y p-P70S6K en la corteza y el hipocampo del grupo ELCI aumentaron significativamente, y estos cambios fueron revertidos significativamente ELCI por el acteoside. Sin embargo, el efecto del acteoside sobre la señalización de mTOR fue notablemente bloqueado por la rapamicina, un inhibidor específico de la señalización de mTOR. El acteoside puede atenuar el deterioro de la memoria y mejorar el daño neuronal y la plasticidad sináptica en ratas con depresión, probablemente mediante la inhibición de la vía de señalización mTOR. Acteoside puede servir como un reactivo novedoso para la prevención de la depresión.

RESUMO

BACKGROUND: Systemic hypertension (SH) is the main risk factor to cognitive deterioration, whereas visuospatial memory is more vulnerable to ageing. Some antihypertensive agents have a neuroprotector effect, however, such effects could be masked by comorbidities and/or the lack of effective control on the arterial pressure of patients. OBJECTIVE: To assess this, the evaluation of incidental visuospatial memory of SH patients and the relation to the treatment received and the effective control of pressure were made. METHOD: 80 patients (46 woman) were included grouped by the received medication: angiotensin 2 receptor blockers (ARB) or angiotensin converting enzyme inhibitors (ACEI). A multiple correlation analysis between visuospatial scores and clinical variables was made; also, a mixed model analysis (fixed factors: treatment, pressure control, diabetes comorbidity; aleatory factors: age, schooling, months from SH diagnoses). RESULTS: Half of the patients had a controlled pressure, from them the higher proportion received ARB, and a minor number of patients received ACEI. The normotensive patients receiving ACEI were inefficient whereas the hypertensive patients were more efficient. The systolic pressure was negatively related with the visuospatial scores in spite of no correlations occurred with MoCA and Raven tests. CONCLUSIONS: The visuospatial incidental/intentional scores were negatively correlated with systolic pressure. The efficiency in the visuospatial ability depends on the interaction of treatment and effective control of blood pressure. The interaction between treatment and effective pressure control must be taken in count when cognitive deterioration is studied.

ANTECEDENTES: La hipertensión arterial sistémica (HAS) es el principal factor de riesgo para el deterioro cognitivo; por otro lado, la memoria visuoespacial es más vulnerable al envejecimiento. Algunos fármacos antihipertensivos tienen un efecto neuroprotector, pero tal efecto puede enmascararse o bien no manifestarse por comorbilidad o por falta de control efectivo de la presión arterial. OBJETIVO: Evaluar las alteraciones en la memoria visuoespacial incidental de pacientes con HAS en relación con su tratamiento antihipertensivo y su control de la presión. MÉTODO: Se incluyeron 80 pacientes con HAS (46 mujeres), agrupados por su medicación en bloqueadores de los receptores de la angiotensina II (BRA) o inhibidores de la enzima convertidora de angiotensina (IECA). Se realizó un análisis de correlaciones múltiples para los puntajes obtenidos en la prueba de memoria visuoespacial incidental/intencional y un análisis de modelos mixtos (factores fijos: tratamiento, control de la presión y comorbilidad con diabetes; factores aleatorios: edad, escolaridad, meses desde el diagnóstico de HAS y coeficiente intelectual). RESULTADOS: De los pacientes controlados, la mayoría de los que recibían BRA fueron eficientes y los que recibían IECA fueron deficientes. De los que recibían IECA, los descontrolados hipertensos fueron más eficientes que los normotensos. La memoria visuoespacial se correlacionó negativamente con la presión sistólica a pesar de no haber diferencias en MoCA y Raven. CONCLUSIONES: La eficiencia en la memoria visuoespacial dependió de la interacción del tratamiento y el control de la presión. Ambos factores, tratamiento y control efectivo de la presión, deben considerarse en la evaluación del deterioro cognitivo asociado a la HAS.

RESUMO

INTRODUCTION: The Latin American Spanish version of the Face-Name Associative Memory Exam (LAS-FNAME) has shown promise in identifying cognitive changes in those at risk for Alzheimer's disease (AD). However, its applicability for Mild Cognitive Impairment (MCI) detection in the Latin American population remains unexplored. This study aims to analyze the psychometric properties in terms of validity and reliability and diagnostic performance of the LAS-FNAME for the detection of memory disorders in patients with amnestic MCI (aMCI). MATERIALS AND METHODS: The study included 31 participants with aMCI, diagnosed by a neurologist according to Petersen's criteria, and 19 healthy controls. Inclusion criteria for the aMCI group were to be 60 years of age or older, report cognitive complaints, have a memory test score (Craft Story 21) below a -1.5 z-score and have preserved functioning in activities of daily living. Participants completed LAS-FNAME and a comprehensive neuropsychological assessment. RESULTS: LAS-FNAME showed the ability to discriminate against healthy controls from patients with aMCI (AUC= 75) in comparison with a gold-standard memory test (AUC = 69.1). LAS-FNAME also showed evidence of concurrent and divergent validity with a standard memory test (RAVLT) (r = 0.58, p < .001) and with an attention task (Digit Span) (r = -0.37, p = .06). Finally, the reliability index was very high (α = 0.88). DISCUSSION: LAS-FNAME effectively distinguished aMCI patients from healthy controls, suggesting its potential for detecting early cognitive changes in Alzheimer's prodromal stages among Spanish speakers.

RESUMO

India's commercial advancement and development depend heavily on agriculture. A common fruit grown in tropical settings is citrus. A professional judgment is required while analyzing an illness because different diseases have slight variati ons in their symptoms. In order to recognize and classify diseases in citrus fruits and leaves, a customized CNN - based approach that links CNN with LSTM was developed in this research. By using a CNN - based method, it is possible to automatically differenti ate from healthier fruits and leaves and those that have diseases such fruit blight, fruit greening, fruit scab, and melanoses. In terms of performance, the proposed approach achieves 96% accuracy, 98% sensitivity, 96% Recall, and an F1 - score of 92% for ci trus fruit and leave identification and classification and the proposed method was compared with KNN, SVM, and CNN and concluded that the proposed CNN - based model is more accurate and effective at identifying illnesses in citrus fruits and leaves.

RESUMO

Resumo Recuperamos memórias do Instituto Fernandes Figueira via o cuidado que reúne crianças doentes e suas mães. A categoria analítica geração sustenta o argumento do instituto como espaço de experiências e memórias. Interpretamos três fontes de memórias: (1) a pesquisa de Marismary Horsth De Seta com a geração que chegou no instituto na década de 1940; (2) o relatório de atividades do instituto de 1973; (3) três entrevistas com trabalhadores admitidos na década de 1980. Concluímos que o cuidado com as crianças e, por conseguinte, um olhar para as mulheres nessa relação se dão em sintonia com a transição epidemiológica global, complexificando o perfil da atenção do instituto.

Abstract Memories of care involving sick children and their mothers at the Fernandes Figueira Institute (Instituto Fernandes Figueira) are retrieved. The analysis using a generational perspective reveals the institute as a space of experiences and memories. Three sources of memories are analysed: (1) the research by Marismary Horsth De Seta with the generation that reached the institute in the 1940s; (2) the institute's 1973 activity report; (3) three interviews with workers admitted in the 1980s. It is concluded that care for children, and therefore interest in their mothers, is aligned with the global epidemiological transition, increasing the complexity of the profile of care given at the institute.

RESUMO

Abstract Background Memory complaints are frequent in older adults and are associated with higher risk of cognitive decline. Objective To investigate the functional outcome of individuals with memory complaints followed up at primary care centers. Methods Data were collected between 2016 e 2020 in primary health care centers in Brazil. Patients underwent the Brief Cognitive Screening Battery, and the Functional Activities Questionnaire. Results The initial sample (2016) comprised 91 individuals classified into those with subjective cognitive decline (SCD, n = 15), mild cognitive impairment (MCI, n = 45), or dementia (n = 31). During follow-up, 8 individuals (8.8% of the initial sample) died and 26 (28.5% of the initial sample) were not found. Fifty-seven participants underwent clinical reassessment. Of 15 individuals with SCD, 7 were not found (46.7%), 4 (26.7%) progressed to MCI, and 4 (26.7%) remained stable. Of 45 individuals with MCI, 11 were not found (24.4%), 2 (4.4%) died, 6 (13.4%) progressed to dementia, 12 (26.7%) regressed to SCD, and 14 (31.1%) remained stable. Of 31 individuals with dementia, 8 were not found (25.8%), 6 (19.4%) died, 2 (6.5%) regressed to SCD, 7 (22.6%) regressed to MCI, and 8 remained stable (25.8%). Clinical improvement was due to the treatment of reversible causes, such as B12 hypovitaminosis and mood disorders. Older age, lower Mini-Mental State Examination, and higher scores of memory complaint, but not the use of benzodiazepines and of proton pump inhibitors, were predictors of functional status. Conclusion Despite their limits (short sample size, missing data), these results support the idea that adequate screening, follow-up, and treatment of reversible causes of dementia in primary care are essential.

Resumo Antecedentes Queixas de memória são frequentes em idosos e estão associadas ao maior risco de declínio cognitivo. Objetivo Investigar o desfecho funcional de indivíduos com queixas de memória acompanhados em centros atenção primária. Métodos Os dados foram coletados entre 2016 e 2020 em centros de atenção primária à saúde no Brasil. Os pacientes foram submetidos à Bateria Cognitiva Breve e ao Questionário de Atividades Funcionais. Resultados A amostra inicial (2016) foi composta por 91 indivíduos, classificados como tendo declínio cognitivo subjetivo (DCS, n = 15), comprometimento cognitivo leve (CCL, n = 45), ou demência (n = 31). Durante o seguimento, 8 indivíduos (8,8% da amostra inicial) faleceram e 26 (28,5% da amostra inicial) não foram encontrados. Cinquenta e sete participantes foram submetidos à reavaliação clínica. Dos 15 indivíduos com DCS, 7 não foram encontrados (46,7%), 4 (26,7%) declinaram para CCL e 4 (26,7%) permaneceram estáveis. Dos 45 indivíduos com CCL, 11 não foram encontrados (24,4%), 2 (4,4%) morreram, 6 (13,4%) declinaram para demência, 12 (26,7%) evoluíram para DCS e 14 (31,1%) permaneceram estáveis. Dos 31 indivíduos com demência, 8 não foram encontrados, (25,8%), 6 (19,4%) morreram, 2 (6,5%) evoluíram para DCS e 7 (22,6%) para CCL; e 8 permaneceram estáveis (25,8%). A melhora clínica deveu-se ao tratamento de causas reversíveis, como hipovitaminose B12 e transtornos de humor. A idade avançada, a baixa pontuação no Mini-Exame do Estado Mental e os escores de queixa de memória mais altos, mas não o uso de benzodiazepínicos e inibidores da bomba de prótons, foram preditores de declínio funcional. Conclusão Apesar de suas limitações (amostra pequena, dados ausentes), esses resultados corroboram que a triagem adequada, o acompanhamento e o tratamento de causas reversíveis de demência na atenção primária são essenciais.

RESUMO

ABSTRACT The majority of people with dementia live in low or middle-income countries (LMICs) where resources that play a crucial role in brain health, such as quality education, are still not widely available. In Brazil, illiteracy remains a prevalent issue, especially in communities with lower socioeconomic status (SES). The PROAME study set out to explore basic education in illiterate adults as a means to improve cognitive reserve. Objective: This manuscript aims to explore the relationship between SES and learning, as well as cognitive outcomes, in an older illiterate population. Methods: This six-month clinical trial (NCT04473235) involved 108 participants, of which 77 concluded all assessments, enrolled in late-life basic education. SES assessments included Quality of Urban Living Index, Municipal Human Development Index and Household SES calculated for each participant. Cognitive assessments encompassed the Free and Cued Selective Reminding Test (FCSRT), a word list to assess reading, and the Beta III matrix. Results: The sample consisted primarily of women, with a mean age of 58.5. Participants improved their reading (p=0.01) and their FCSRT (p=0.003). Regarding episodic memory, women outperformed men (p=0.007) and younger participants improved more than their older counterparts (p=0.001). There was no association observed between SES and cognitive outcomes. Conclusion: Irrespective of SES, participants demonstrated positive outcomes after attending basic education. These findings highlight that late life education could be an important non-pharmacologic preventative measure, especially in LMICs.

RESUMO A maioria das pessoas com demência vive em países de baixa/média renda, onde recursos essenciais para a saúde cerebral, como educação de qualidade, ainda não são amplamente acessíveis. No Brasil, o analfabetismo ainda é frequente, especialmente em comunidades de baixo nível socioeconômico. O estudo PROAME teve como objetivo explorar a educação básica tardia em pessoas analfabetas como ferramenta para o aumento da reserva cognitiva. Objetivo: Investigar a relação entre nível socioeconômico com aprendizado e com desempenho em testes cognitivos, em adultos analfabetos. Métodos: Este estudo clínico de seis meses (NCT04473235) contou com 108 participantes inscritos no projeto Educação para Jovens e Adultos (EJA), dos quais 77 completaram os testes. O nível socioeconômico de cada participante foi medido usando-se: o Índice de Qualidade de Vida Urbana, o Índice de Desenvolvimento Humano Municipal e o nível socioeconômico doméstico. Avaliações cognitivas incluíram: o Teste de Recordação Seletiva Livre e Guiada (TRSLG), uma lista de palavras para avaliar leitura e a matriz Beta III. Resultados: A amostra era predominantemente feminina, com idade média de 58,5. Os participantes melhoraram a leitura (p=0,01) e o TRSLG (p=0,003). Com relação à memoria episódica, as mulheres tiveram resultados superiores aos dos homens (p=0,007) e participantes mais jovens melhoraram mais que seus colegas mais velhos (p=0,001). Não foi observada nenhuma relação entre o nível socioeconômico e o desempenho cognitivo. Conclusão: Independentemente do nível socioeconômico, participantes obtiveram resultados positivos após frequentar a educação básica. Isso sugere que a educação tardia pode ser uma medida preventiva não farmacológica importante, especialmente em países de baixa/média renda.

RESUMO

ABSTRACT Purpose: to compare temporal auditory processing (temporal ordering) and phonological processing skills in bilingual and monolingual subjects. Methods: 100 undergraduate and postgraduate university students divided into a bilingual group (BG; n = 50) and a monolingual group (MG; n = 50). The study assessed the two groups' phonological processing skills (phonological awareness, working memory - phonological loop, and rapid lexicon access) and temporal auditory processing skills (Frequency Pattern and Duration Pattern Tests). The Mann-Whitney test (p = 0.05) was used for statistical analysis. Results: BG performed better than MG in phonological awareness and phonological working memory tasks - nonword repetition and rapid naming tasks, except for color naming, and the two auditory processing tests. Conclusion: Bilinguals performed better on phonological and auditory tests. These skills help them identify and discriminate variations in the phonology of both languages, influencing their performance.

RESUMO Objetivo: comparar as habilidades do processamento auditivo temporal (ordenação temporal) e do processamento fonológico em sujeitos bilíngues e monolíngues. Métodos: participaram 100 estudantes universitários (graduação e pós-graduação) divididos em Grupo Bilíngue (GB n=50) e Grupo Monolíngue (GM n=50). As habilidades do Processamento Fonológico (consciência fonológica, memória de trabalho - alça fonológica e acesso rápido ao léxico) e habilidades temporais do Processamento Auditivo (testes de Padrão de Frequência e Padrão de Duração) dos dois grupos, foram avaliadas. Foi utilizado, para análise estatística, o teste de Mann-Whitney (p=0,05). Resultados: observou-se melhor desempenho do GB em tarefas de consciência fonológica e memória de trabalho fonológica - repetição de não-palavras, em tarefas de nomeação rápida, exceto para nomeação de cores, e melhor desempenho nos dois testes de processamento auditivo, comparado com o desempenho do GM. Conclusão: indivíduos bilíngues apresentam melhor desempenho em testes fonológicos e auditivos. Essas habilidades favorecem a identificação e discriminação de variações na fonologia de ambos os idiomas, influenciando seu desempenho.

RESUMO

Resumo: As representações sociais são elaboradas a partir da inserção de determinado objeto em um sistema de conhecimentos preexistentes, processo este, denominado de ancoragem. Este estudo buscou analisar a relação entre memória e ancoragem nas representações sociais da edição genética de embriões humanos. Foram conduzidas 40 entrevistas com pessoas adultas maiores de 18 anos sobre opiniões acerca da edição genética de embriões humanos. Realizou-se uma Análise de Conteúdo Temática a partir das entrevistas. As memórias evocadas discutem os avanços da ciência e o surgimento de outras biotecnologias no passado. O risco de práticas eugenistas e erros da ciência também foram rememorados. As memórias mostram duas tendências concomitantes entre os entrevistados: a busca pela familiarização da edição genética e/ou o distanciamento deste objeto. Os posicionamentos revelam um pensamento condicional, apontando para os aspectos controversos e esperançosos e as consequências positivas e negativas que podem ocorrer a partir da aplicação dessa tecnologia.

Abstract: Social representations are developed by inserting a given object into a system of preexisting knowledge, a process known as anchoring. This study sought to analyze the relationship between memory and anchoring in social representations of human embryo genetic editing. Forty interviews were conducted with adults over 18 years of age about their opinions about human embryo genetic editing. A Thematic Content Analysis was carried out based on the interviews. The memories evoked discuss scientific advances and the emergence of other biotechnologies in the past. The risk of eugenic practices and scientific errors were also recalled. The memories show two concomitant trends among the interviewees: the search for familiarization with genetic editing and/or distancing from this object. The positions reveal conditional thinking, pointing to the controversial and hopeful aspects and the positive and negative consequences that may occur from the application of this technology.

RESUMO

El propósito de esta investigación consistió en estudiar el rol del vocabulario, la memoria de trabajo, la teoría de la mente y la atención sostenida en la comprensión de narraciones orales y la generación de inferencia en niños de entre 7 y 11 años. Para ello, se utilizaron las habilidades de comprensión lectora como criterio para establecer los grupos de cohorte del estudio. La muestra, conformada por 126 niños colombianos hispanohablantes, fue evaluada en tareas de comprensión de narraciones orales, así como mediante pruebas estandarizadas en vocabulario, memoria de trabajo, teoría de la mente y atención sostenida. Los resultados mostraron diferencias significativas entre el grupo de baja comprensión lectora respecto al grupo de comparación con mejores desempeños en comprensión en la medida de vocabulario y en la medida de comprensión de narraciones con apoyos visuales, como producto de una diferencia significativa en la respuesta a preguntas de inferencia emocional. El análisis correlacional mostró vínculos significativos entre el vocabulario y todas las medidas de comprensión evaluadas. Por su parte, la memoria de trabajo se correlacionó con todas las medidas de desempeño en comprensión, excepto con la respuesta a preguntas inferenciales. Finalmente, la teoría de la mente mostró una correlación significativa con la respuesta a preguntas de inferencias emocionales y con las medidas de comprensión de narraciones sin apoyos visuales.

O objetivo desta pesquisa foi estudar o papel do vocabulário, da memória de trabalho, da Teoria da Mente e da atenção sustentada na compreensão de narrativas orais e na geração de inferência em crianças de 7 a 11 anos. Para isso, foram utilizadas as habilidades de compreensão de leitura como critério para estabelecer os grupos de coorte do estudo. Um total de 126 crianças colombianas, hispano-falantes, foram avaliadas por meio de tarefas de compreensão de narrativas orais, testes padronizados de vocabulário, memória de trabalho, Teoria da Mente e atenção sustentada. Os resultados indicaram diferenças significativas entre o grupo de baixa compreensão leitora em relação ao grupo de comparação, com melhores desempenhos em compreensão no teste de vocabulário e no teste de compreensão de narrativas com apoios visuais, como resultado de uma diferença significativa na resposta a perguntas de inferência emocional. A análise correlacional mostrou vínculos significativos entre o vocabulário e todas as medidas de compreensão avaliadas. Além disso, a memória de trabalho correlacionou-se com quase todas as medidas de desempenho em compreensão, exceto com a resposta a perguntas inferenciais. Finalmente, a Teoria da Mente apresentou uma correlação significativa com a resposta às perguntas de inferências emocionais e com as medidas de compreensão de narrativas sem apoio visual.

The purpose of this study was to analyze the role of vocabulary, working memory, Theory of Mind, and sustained attention in the comprehension of oral narratives and the generation of inferences in children aged 7 to 11. Reading comprehension skills were used as the criterion to establish the study's cohort groups. A total of 126 Spanish-speaking Colombian children participated in the study. They were assessed using tasks that measured comprehension of oral narratives, as well as standardized tests of vocabulary, working memory, Theory of Mind, and sustained attention. The results indicated a significant difference in vocabulary between the group of poor comprehenders and the comparison group with better comprehension performance. The poor comprehenders also performed worse than the comparison group in the narrative comprehension test with visual support, as a result of significant differences in responding to emotional inference questions. The correlational analysis showed that the vocabulary variable was associated with all measures of oral narrative comprehension. Additionally, working memory correlated with almost all measures of oral narrative comprehension, except for answering inference questions when the text did not have visual support. Finally, Theory of Mind demonstrated a significant correlation with answering emotional inference questions and the measures without visual support.
