Triadic interactions, parental reflective functioning, and early social-emotional difficulties.

Early childhood is a critical period for social-emotional development; during this period, the child's immediate family is the system with the greatest influence on his or her development. The parents' capacity to reflect on the children's ability to process and interact within a social environment, called parental reflective functioning (RF), is considered an important factor in protecting children from highly prevalent social-emotional difficulties and may have a strong influence on children's long-term development. OBJECTIVE: To describe and analyze the relationships among parents' RF, the quality of the mother-father-child triadic interaction, and children's social-emotional difficulties. METHOD: A nonexperimental, cross-sectional, correlational study was conducted. Fifty mother-father-child triads, each in a current relationship that included at least one child aged 12-36 months, were evaluated. Sociodemographic background, triadic interaction, parental RF, and social-emotional difficulties were assessed. RESULTS: Triadic interaction was found to have a significant effect on the child's social-emotional difficulties, explaining 9% of the variance. In addition, the mothers' RF had a significant influence on triadic interaction, explaining 19% of the variance. An exploratory finding showed that triadic interaction mediates the relationship between mothers' RF and children's social-emotional difficulties.

La temprana niñez es un período crítico para el desarrollo socio-emocional; durante este período, el núcleo familiar del niño es el sistema con la mayor influencia en su desarrollo. La capacidad de los padres de reflexionar sobre la habilidad del niño de procesar e interactuar dentro del ambiente social, llamada la función reflexiva de los padres (RF), es considerada un factor importante en la protección del niño en cuanto a dificultades socio-emocionales altamente prevalentes y pudiera tener una fuerte influencia en el desarrollo del niño a largo plazo. OBJETIVO: Describir y analizar la relación entre la función reflexiva de los padres (RF), la calidad de la interacción tríadica entre mamá, papá y niño, y las dificultades socio-emocionales de los niños. MÉTODO: Se llevó a cabo un estudio no experimental, transversal y correlacional. Se evaluaron cincuenta tríadas de mamá, papá y niño, cada una de ellas en una relación presente que incluía por lo menos un niño de edad entre 12 y 36 meses. Se evaluaron el trasfondo demográfico, la interacción tríadica, la RF de los padres, así como las dificultades socio-emocionales. RESULTADOS: Se encontró que las interacciones tríadicas tenían un efecto significativo en las dificultades socio-emocionales del niño, lo cual explica el 9% de la variación. Adicionalmente, la RF de las mamás tuvo una influencia significativa en la interacción tríadica, lo cual explica el 19% de la variación. Un resultado exploratorio mostró que la interacción tríadica sirve de mediadora en la relación entre la RF de la mamá y las dificultades socio-emocionales de los niños.

La petite enfance est une période critique pour le développement socio-émotionnel. Durant cette période la famille proche de l'enfant est le système ayant la plus grande influence sur son développement. La capacité des parents à réfléchir à la capacité des enfants à traiter et à interagir avec l'environnement social, appelée le fonctionnement de réflexion parentale (abrégé en anglais RF), est considérée comme étant un facteur important qui protège les enfants de difficultés socio-émotionnelles extrêmement prévalente et qui peut avoir une forte influence sur le développement long-terme des enfants. OBJECTIF: Décrire et analyser les relations entre le RF des parents, la qualité de l'interaction triadique mère-père-enfant, et les difficultés socio-émotionnelles des enfants. MÉTHODE: Une étude non-expérimentale, corrélationnelle, avec une coupe transversale a été effectuée. Cinquante triades mère-père-enfant, chacune dans la relation actuelle qui incluait au moins un enfant âgé de 12 à 36 mois, ont été évaluées. Le contexte sociodémographique, l'interaction triadique, le RF parents, et les difficultés socio-émotionnelles ont été évalués. RÉSULTATS: On a trouvé que l'interaction triadique avait un effet important sur les difficultés socio-émotionnelles de l'enfant, expliquant 9% de l'écart. De plus, le RF des mères s'est avéré avoir une influence importante sur l'interaction triadique, expliquant 19% de l'écart. Un résultat exploratoire a montré que l'interaction triadique affecte la relation entre es le RF des mères et les difficultés socio-émotionnelles des enfants.

[Facilitators and barriers regarding end of life care at nursing homes: A focus group study]. / Dificultades y factores favorables para la atención al final de la vida en residencias de ancianos: un estudio con grupos focales.

AIM: To identify the facilitators and barriers experienced by professional related to end of life care in nursing homes. DESIGN: Descriptive qualitative research with phenomenological orientation, through content analysis. PLACEMENT: Nursing Homes at Primary Care District in Granada (Spain). PARTICIPANTS: Fifteen clinical professionals with, at least 6 months of experience in nursing homes, without specific background in palliative care. METHODS: Three focus groups were undertaken with professionals of different disciplines and nursing homes. Interviews were recorded and transcribed literally. An open and axial coding was performed to identify relevant categories. RESULTS: Professionals identified difficulties in the communication with families related to relatives' feelings of guilt, difficulty in understanding the deterioration of their relative, and addressing too late the issue of death. Regarding decision making, professionals recognized that they do not encourage participation of patients. Advance directives are valued as a necessary tool, but they do not contemplate implementing them systematically. Other difficulties that professionals highlighted are lack of coordination with other professionals, related to misunderstanding of patients' needs, as well as lack of training, and lack of material and human resources. Facilitators include relationships with primary care teams. CONCLUSION: It is necessary to improve communication among nursing homes professionals, families, patients and other health workers.

Attention deficit hyperactivity disorder: Neuropsychological profile and study of its impact on executive functions and academic performance.

INTRODUCTION: The aim of the study was to describe the neuropsychological profile of patients with attention deficit hyperactivity disorder (ADHD) and the impact of the disorder on executive functioning and academic performance. PATIENTS AND METHODS: We conducted a retrospective observational and analytical study. The sample consisted of 24 children with a diagnosis of ADHD (aged 6-15 years) without pharmacological treatment and 24 controls without ADHD (aged 7-15 years). A comprehensive neuropsychological evaluation was carried out, encompassing major cognitive domains, in addition to assessment of executive functioning and psychopathological symptoms through the administration of questionnaires to parents and teachers. RESULTS: The cognitive profile of the ADHD group was characterized by overall scores (including executive functions and academic abilities) in the normal range (z scores between -1 and 1), although significantly lower compared to the control group. Over half of the patients with ADHD (58%) had associated specific learning disorders. Furthermore, teachers tended to report executive function difficulties more frequently in male students. CONCLUSIONS: In the study sample, the group of patients with ADHD exhibited cognitive performance within the normal range, although with lower scores compared to controls. Behavioural rating scales provide valuable information about functioning outside the clinic, but may yield biased results on account of the focus on externalising symptoms. The neuropsychological evaluation is a useful tool that can facilitate the diagnosis of ADHD and an effective response to the needs and characteristics of patients and families.

Adult refugees' perspectives on the impact of trauma and post-migration hardships on learning.

Background: Research shows that adult refugees' well-being and future in the reception country heavily depend on successfully learning the host language. However, we know little about how adult learners from refugee backgrounds experience the impact of trauma and adversity on their learning.Objective: The current study aims to investigate the perspectives of adult refugee learners on whether and how trauma and other adversity affect their learning.Methods: We conducted in-depth interviews with 22 adult refugees (10 women) attending the Norwegian Introduction Programme (NIP). The participants came from six Middle Eastern, Central Asian, and African countries. Two questionnaires were included, one about past stressful life events (SLESQ-Revised), and one about mental health symptoms and current psychological distress following potentially traumatic experiences (PCL-5).Results: Participants held varying beliefs about trauma's impact on learning: that it had a constant impact, that it was situational, or that it had no impact. Other aspects they brought up as having an essential effect on learning and school attendance include psychological burdens from past and present school experiences, and post-migration hardships such as loneliness, depression, ongoing violence, and negative social control. Post-migration trauma and hardships exacerbated the burden of previous trauma and were frequently associated with a greater negative influence on learning.Conclusion: This study adds new insights from adult refugee learners themselves into how post-migration hardships as well as trauma can impact their learning, and the importance of recognising their struggles. A safe space is required for refugees to open up about their difficulties in life and with learning. This knowledge can be used to enhance teaching practices, foster better teacher-student relationships, and inform policy-making decisions, ultimately benefiting both individuals and society.

Adult refugee learners' own perspectives on the impact of trauma on learning varied from constant to situational to no impact at all.Other factors identified as impacting learning and school attendance included, amongst others, psychological burdens from past and present school experiences, ongoing violence, forced family separation, and negative social control.Post-migration trauma and hardships were frequently associated with a greater negative influence on learning than the burden of previous trauma.

Nutritional status and prevalence of dysphagia in cerebral palsy: usefulness of the Eating and Drinking Ability Classification System scale and correlation with the degree of motor impairment according to the Gross Motor Function Classification System.

INTRODUCTION AND OBJECTIVES: Digestive disorders are one of the most common comorbidities among children with cerebral palsy (CP). The aim of this study is to examine the nutritional status of patients with CP, the prevalence of dysphagia by degree of motor impairment, and the impact of digestive disorders on quality of life. MATERIAL AND METHODS: We conducted a descriptive, cross-sectional, open-label study of out-patients with CP from a tertiary hospital in the Region of Madrid using a structured interview, classifying dysphagia using the Eating and Drinking Ability Classification System (EDACS). We gathered demographical and anthropometric data, and analysed the correlation between severity of dysphagia and functional status as measured with the Gross Motor Function Classification System (GMFCS). RESULTS: Our sample included 44 patients (65.9% boys), with a mean (standard deviation) age of 9.34 (5) years and a mean BMI of 18.5 (4.9). Forty-three percent presented safety and efficiency limitations (EDACS level > II). Safety and efficiency limitations were associated with more extensive motor involvement (60% had tetraparesis), more varied clinical manifestations (87% had mixed forms) and poorer functional capacity (100% on GMFCS V). The impact on nutritional status increased with higher EDACS and GMFCS scores. CONCLUSIONS: This is the first study into the usefulness of the EDACS scale in a representative sample of Spanish children and adolescents with CP. Our findings underscore the importance of screening for dysphagia in these patients, regardless of the level of motor impairment, and the need for early treatment to prevent the potential consequences: malnutrition (impaired growth, micronutrient deficiencies, osteopaenia, etc.), microaspiration, or recurrent infections that may worsen patients' neurological status.

Bing-Neel syndrome presenting with bilateral lumbar radiculopathy: A case report of a rare clinical entity.

The differential diagnosis of bilateral lower extremity weakness is broad. We present a very rare case of a 48-year old male patient, with walking difficulties due to Bing-Neel syndrome. On clinical examination, there was a significant loss of muscle power in all his lower extremities key-muscle groups. The lumbar spine magnetic resonance imaging (MRI) showed only mild degenerative changes, whereas the MRI of the head indicated a diffuse meningeal thickening at the right temporal region, characterized by significant enhancement after contrast administration. Serum protein electrophoresis detected an IgM-kappa monoclonal protein. The patient received intrathecal chemotherapy with methotrexate and cytarabine, and was started on oral ibrutinib 420mg daily. In conclusion, a past medical history of Waldenstrom macroglobulinemia in conjunction with neurological manifestations should alert the treating physician for Bing-Neel syndrome. A complete diagnostic imaging and serologic protocol helps in setting the final diagnosis. Steroids are part of the treatment, but should be given after the diagnosis is set. Neurosurgical intervention is indicated for histologic confirmation in the case of diagnostic uncertainty.

A network analysis of postmigration living difficulties in refugees and asylum seekers.

Background: The prevalence of mental disorders among asylum seekers and refugees is elevated compared to the general population. The importance of post-migration living difficulties (PMLDs), stressors faced after displacement, has recently been recognized due to research demonstrating their moderating role of on mental health outcomes. Traditionally, PMLDs were investigated as count variables or latent variables, disregarding plausible interrelationships among them. Objectives: To use network analysis to investigate the associations among PMLDs. Methods: Based on a cross-sectional measurement of seventeen PMLDs in a clinical sample of traumatized asylum seekers and refugees (N = 151), a partial correlation network was estimated, and its characteristics assessed. Results: The network consisted of 71 of the 120 possible edges. The strongest edge was found between 'Communication difficulties' and 'Discrimination'. 'Loneliness, boredom, or isolation' had highest predictability. Conclusion: Our finding of an association between communication difficulties and discrimination has been documented before and is of importance given the known negative impact of discrimination on mental and physical health outcomes. The high predictability of isolation is indicative of multiple associations with other PMLDs and highlights its importance among the investigated population. Our results are limited by the cross-sectional nature of our study and the relatively modest sample size.

Antecedentes: la prevalencia de trastornos mentales entre los solicitantes de asilo y los refugiados es elevada en comparación con la población general. La importancia de las dificultades de vida, posteriores a la migración (PMLD, por sus siglas en inglés), factores estresantes que se enfrentan después del desplazamiento, ha sido reconocida recientemente debido a investigaciones que demuestran su papel moderador en los resultados de salud mental. Tradicionalmente, los PMLD se investigaban como variables de recuento o variables latentes, sin tener en cuenta las posibles interrelaciones entre ellas.Objetivos: Utilizar el análisis de redes para investigar las asociaciones entre PMLD.Métodos: a partir de una medición transversal de diecisiete PMLDs en una muestra clínica de solicitantes de asilo y refugiados traumatizados (N = 151), se estimó una red de correlación parcial y se evaluaron sus características.Resultados: La red constaba de 71 de las 120 posibles aristas. La arista más fuerte se encontró entre 'Dificultades de comunicación' y 'Discriminación'. 'La soledad, el aburrimiento o el aislamiento' tenían la máxima predictibilidad.Conclusión: Nuestro hallazgo de una asociación entre las dificultades de comunicación y la discriminación ha sido documentado anteriormente y es de importancia dado el conocido impacto negativo de la discriminación en los resultados de salud física y mental. La alta predictibilidad del aislamiento es indicativa de múltiples asociaciones con otros PMLDs y destaca su importancia entre la población investigada. Nuestros resultados están limitados por la naturaleza transversal de nuestro estudio y el tamaño de muestra relativamente modesto.

Emotional and behavioural difficulties and prosocial behaviour in adolescents: A latent profile analysis. / Dificultades emocionales y conductuales y comportamiento prosocial en adolescentes: un análisis de perfiles latentes.

INTRODUCTION: The purpose of this study was to identify homogenous subgroups of adolescents with emotional and behavioural difficulties using latent profile analysis. The relationship between the latent profile classes and socio-emotional and school adjustment was also analysed. MATERIALS AND METHODS: A total of 1,506 students, 667 men (44.3%) were selected by random cluster sampling. The mean age was 16.15 years (SD=1.36). The instruments used were the Strengths and Difficulties Questionnaire, the Personal Wellbeing Index-School Version, The 10-item Positive and Negative Affect Schedule for Children, the Prodromal Questionnaire Brief, the Paykel Suicide Scale, the Cyberbullying-Brief Questionnaire, the Penn Matrix Reasoning Test, and the school performance assessment. RESULTS: A total of 7.7% of adolescents obtained risk scores for mental health difficulties. We identified 3 mental health subgroups named: Low risk, Externalizing, and Internalizing. These 3 latent classes demonstrated a differential pattern in terms of socio-emotional adjustment and academic performance. CONCLUSIONS: To identify and validate risk groups of youths for emotional and behavioural problems allows implementing measures to promote emotional well-being and prevent mental health problems. Future studies should continue to analyse young people with emotional and behavioural problems longitudinally and to incorporate new forms of assessment and intervention.

A fase terminal do filho com câncer: percepções dos profissionais hospitalares / The terminal phase of children with cancer: perceptions of hospital professionals / La fase terminal del hijo con cáncer: percepciones de los profesionales del hospital

O confronto com o câncer de um filho e a percepção da sua morte como inevitável dão lugar a experiências parentais relevantes para a pesquisa científica. Este estudo teve como objetivo investigar, por meio da percepção dos profissionais hospitalares, o modo como os pais experienciam a fase terminal e fim de vida do filho com câncer para melhor compreender os processos psicoemocionais experienciados por esses pais diante da cronicidade da doença e da morte do filho. No sentido de alcançar esse objetivo, realizou-se um estudo qualitativo de tipo fenomenológico envolvendo 17 profissionais de dois hospitais portugueses de referência em oncologia pediátrica. Os dados foram recolhidos com recurso a um guia de entrevista semiestruturada. Na percepção dos profissionais hospitalares, os resultados evidenciam que esses pais experienciam múltiplas dificuldades e preocupações na fase terminal da doença do filho e no pós-morte, bem como um sofrimento extremo e desestruturação biopsicossocial e espiritual na família. O conhecimento aprofundado da fenomenologia desses processos é essencial para o desenho e a implementação de intervenções emocionais, cognitivas, comportamentais e sociais mais ajustadas às dificuldades e preocupações parentais vividas no fim de vida e pós-morte.(AU)

Coping with children's cancer and the perception of their inevitable death give rise to parental experiences that are important to study. This study aimed to investigate, based on hospital professionals' perspectives, how parents experience the terminal phase and end of life of their children suffering from cancer to better understand the psycho-emotional processes these parents experienced in face of the chronicity of the disease and their children's death. To achieve this objective, a qualitative phenomenological study was carried out involving 17 professionals of two Portuguese hospitals that are reference in pediatric oncology. Data were collected using a semi-structured interview guide. From the perspective of hospital professionals, results show that these parents experience multiple difficulties and concerns in the terminal phase of their children's disease and postmortem, as well as the extreme suffering and biopsychosocial and spiritual disruption of the family. A deeper understanding of the phenomenology of these processes is essential to design and implement better adjusted emotional, cognitive, behavioral, and social interventions aimed at the parental difficulties and concerns experienced at the end of life and after death.(AU)

El enfrentamiento del cáncer de un hijo y la percepción de su muerte como inevitable dan lugar a experiencias parentales importantes que deben ser estudiadas. Este estudio pretende identificar desde la percepción de los profesionales del hospital cómo los padres viven la fase terminal y el final de la vida de su hijo con cáncer con el fin de comprender mejor los procesos psicoemocionales que viven estos padres ante la cronicidad de la enfermedad y la muerte de su hijo. Para ello, se realizó un estudio cualitativo, con enfoque fenomenológico, en el que participaron 17 profesionales de dos hospitales portugueses de referencia en oncología pediátrica. Para recoger los datos se aplicó un guion de entrevista semiestructurada. En cuanto a la percepción de los profesionales del hospital, estos padres experimentaron múltiples dificultades y preocupaciones en la fase terminal de la enfermedad de su hijo y postmuerte, así como un sufrimiento extremo y una desestructuración biopsicosocial y espiritual en la familia. El conocimiento en profundidad de la fenomenología de estos procesos es esencial para elaborar e implementar intervenciones emocionales, cognitivas, conductuales y sociales más acordes a las dificultades y preocupaciones parentales que se experimentan al final de la vida y la postmuerte.(AU)

The Impact of Various Factors on the Difficulties in Learning and Teaching Strategies for Histology / El Impacto de Diversos Factores en las Dificultades en el Aprendizaje y las Estrategias de Enseñanza de Histología

SUMMARY: Histology is considered one of the most important but challenging topics in health sciences. Deficiencies in teaching and general histology directly affect the student's understanding, performance and promote dynamism and integration while covering the primary curriculum. The goal of the current study was to assess and provide a better experience of difficulties in learning histology, examine some standard teaching strategies, and determine how to implement suitable changes to improve the curriculum from students' perspectives. The study comprised of a self-administered questionnaire that included descriptive questions. Data was collected based on the survey conducted via 100 students studying histology. Data was analyzed further qualitatively and quantitatively to elaborate on the difficulties in this area. Many of them strongly agreed that the lack of essential comprehension regarding using light and electron microscopes resulted in challenges with comprehending and identifying tissue samples for image identification due to inadequate anatomical knowledge. Moreover, according to students, some difficulties understood the topic, perception of new terminologies, and insufficient teaching strategies to grasp students' interests. They also agreed that improvement was needed in terms of the modes of teaching employed by histology teachers; they felt that modern education techniques based on practical tasks should be incorporated to stimulate student interest and make understanding histological concepts easier. The Institution should modify the teaching system to allocate more time to relevant subjects to make this subject matter more interesting. This survey-based study evaluated that students faced some challenges while studying the current curriculum of histology. From the student's perspective, it is identified that some changes are needed to improve the course curriculum and way of teaching to make it more understandable.

La histología se considera uno de los temas más importantes pero desafiantes de las ciencias de la salud. Las deficiencias en la enseñanza y en la histología general afectan directamente la comprensión, el desempeño del estudiante y promueven el dinamismo y la integración al abarcar el currículo primario. El objetivo del estudio actual fue evaluar y proporcionar una mejor experiencia de las dificultades en el aprendizaje de histología, examinar algunas estrategias de enseñanza estándar y determinar cómo implementar cambios adecuados para mejorar el plan de estudios desde la perspectiva de los estudiantes. El estudio constaba de un cuestionario auto administrado que incluía preguntas descriptivas. Los datos se recopilaron a partir de una encuesta realizada a 100 estudiantes de histología. Los datos se analizaron más a fondo de forma cualitativa y cuantitativa para profundizar en las dificultades en esta área. Muchos de ellos estuvieron totalmente de acuerdo en que la falta de comprensión esencial sobre el uso de microscopios ópticos y electrónicos resultó en desafíos para comprender e identificar muestras de tejido para la identificación de imágenes debido a un conocimiento anatómico inadecuado. Además, según los estudiantes, algunas dificultades en la comprensión del tema, percepción de nuevas terminologías y estrategias de enseñanza insuficientes para captar los intereses de los estudiantes. También coincidieron en que era necesario mejorar los métodos de enseñanza empleados por los profesores de histología; sintieron que deberían incorporarse técnicas educativas modernas basadas en tareas prácticas para estimular el interés de los estudiantes y facilitar la comprensión de los conceptos histológicos. La Institución debería modificar el sistema de enseñanza para asignar más tiempo a materias relevantes para hacer esta materia más interesante. Este estudio basado en encuestas evaluó que los estudiantes enfrentaron algunos desafíos mientras estudiaban el plan de estudios actual de histología. Desde la perspectiva del estudiante, se identifica que se necesitan algunos cambios para mejorar el plan de estudios del curso y la forma de enseñar para hacerlo más comprensible.

Percepción de la ansiedad y de las dificultades de aprendizaje según los criterios de la familia y de los profesores de niños con Trastorno por Déficit de Atención e Hiperactividad / Perception of anxiety and learning difficulties according to the criteria of the family and eachers of children with Attention Deficit Hyperactivity Disorder

Resumen Tanto el Trastorno por Déficit de Atención e Hiperactividad (TDAH) como la ansiedad son dos de los trastornos que más se evidencian en la población infanto-juvenil existiendo una correlación entre ambos tal y como se recoge en numerosos estudios. La combinación de ambos trastornos afecta a los procesos de enseñanza-aprendizaje del niño provocando dificultades de aprendizaje (DA) en el mismo. Los objetivos del presente trabajo se basaron en valorar los criterios que evidencian padres y profesores en niños con TDAH para caracterizar el grado de adecuación de la percepción y evaluar si esta se ajusta a la realidad o es insuficiente, si existen diferencias en dicha percepción entre padres y docentes; analizar la conciencia que tienen sobre las posibles DA que puedan presentar, para así aportar orientaciones adecuadas que permitan una favorable inter vención y evolución. La muestra se compone de 137 sujetos con edades comprendidas entre 9 y 15 años con un Coeficiente Intelectual Total (CIT) de entre 80 y 120. Los instrumentos que se utilizaron fueron: la escala de inteligencia de Wechsler para niños-V (WISC-V), el Cuestionario de Ansiedad Estado-Rasgo en Niños(STAI-C), el Sistema de Evaluación de Niños y Adolescentes(SENA) y el Inventario de Problemas en la Escuela (IPE). Como resultado se observa que la ansiedad percibida por estos niños no está relacionada con la que aprecian padres y profesores, sin embargo, estos últimos sí que coinciden en su apreciación.

Abstract Both Attention Deficit Hyperactivity Disorder (ADHD) and anxiety are two of the disorders that are most evident in the infant-juvenile population and there is a correlation between the two, as shown in numerous studies. The combination of both disorders affects the child's teaching-learning processes, causing learning difficulties (LD). The aims of the present study were based on assessing the criteria evidenced by parents and teachers in children with ADHD to characterize the degree of adequacy of perception and to evaluate whether this is in line with real ity or insufficient, whether there are differences in this perception between parents and teachers, and to analyze their awareness of the possible AD they may present, in order to provide appropriate guidelines for favourable intervention and evolution. The sample consisted of 137 subjects aged between 9 and 15 years with a Total IQ (TIQ) between 80 and 120. The instruments used were: the Wechsler Intelligence Scale for Children-V (WISC-V), the State-Trait Anxiety Questionnaire for Children (STAI-C), the Child and Adolescent Assessment System (SENA) and the Inventory of Problems at School (IPE). As a result, it is observed that the anxiety perceived by these children is not related to the anxiety perceived by parents and teachers, although the latter do coincide in their assessment.

Especificidades dos erros cometidos e do tempo despendido na actividade discriminação perceptiva de símbolos gráficos em alunos com dificuldades de aprendizagem / Specifics of errors and time spent in perceptual discrimination of graphic symbols in students with learning difficulties / Particularidades de los errores cometidos y el tiempo empleado en la actividad de la discriminación perceptiva de símbolos gráficos en estudiantes con dificultades de aprendizaje

A discriminação perceptiva de símbolos depende da organização perceptiva do sujeito da ação como sistema bio-psico-social complexo. Objectivo: estudo de especificidades da discriminação perceptiva de símbolos em alunos com dificuldades de aprendizagem. Amostra: 550 participantes ­ 275 com e 275 sem dificuldades de aprendizagem; idades 7 ­ 15 anos; escolaridade ­ 1º, 2º e 3º ciclo do ensino básico. Instrumentos metodológicos ­ entrevista clínico--psicológica, observação psicológica, Teste de Símbolos e Dígitos (SDMT). Resultados: Alunos com dificuldades de aprendizagem tendem a evidenciar mais emparelhamentos dígito-símbolo incorretos e menos corretos e a despenderem bastante mais tempo na execução da tarefa; portanto, executam menos emparelhamentos corretos por minuto, comparativamente a alunos sem dificuldades de aprendizagem. Conclusão: Nas dificuldades de aprendizagem, cometem-se mais erros e assinalam-se menos emparelhamentos correctos na tarefa de emparelhamento, quando há limites no tempo de execução; caso contrário, a disponibilidade de tempo compensa, reduzindo a quantidade de incorreções. Nas dificuldades de aprendizagem, é necessário mais tempo para executar a tarefa de emparelhamento, devido ao processamento de informação mais lento; tempo consumido na decodificação e identificação das correspondências dígito-símbolo e a discriminação perceptiva não se infirma com a rapidez necessária à simultaneidade e automatização do ato. (AU)

The perceptual discrimination of symbols depends on the perceptual organization of the individual as a complex bio-psychosocial system in action. Objective: To study the specifics of perceptual discrimination of symbols in students with learning difficulties. Sample: 550 participants - 275 with learning difficulties and 275 without; aged 7 to 15; educational levels ranging from the 1st to 3rd cycles of basic education. Methodological instruments included clinical-psychological interviews, psychological observations, and the Symbols Digit Modalities Test (SDMT). Results: Students with learning difficulties tend to display more incorrect and fewer correct digit-symbol pairings, and they invest considerably more time in task execution. Consequently, they achieve fewer correct pairings per minute compared to students without learning difficulties. Conclusion: Learning difficulties are associated with increased errors and fewer correct pairings in the task of pairing symbols when time constraints exist. Conversely, when ample time is available, it mitigates the quantity of inaccuracies. Learning difficulties necessitate more time for task completion due to slower information processing. The time spent on decoding, identifying digit-symbol correspondences, and perceptual discrimination does not align with the speed required for simultaneity and automation of the task. (AU)

Muestra: 550 parti-cipantes - 275 con y 275 sin dificultades de aprendizaje; edades de 7 a 15 años; escolaridad - 1º, 2º y 3º ciclo de educación básica. Instrumentos metodológicos: entrevista clínico-psicológica, observación psicológica, Test de Símbolos y Dígitos (SDMT). Resultados: Los estudiantes con dificultades de aprendizaje tienden a mostrar una mayor cantidad de emparejamientos dígito-símbolo incorrectos y menos correctos y dedican mucho más tiempo a la ejecución de la tarea; por lo tanto, realizan menos emparejamientos correctos por minuto, en comparación con los estudiantes sin dificultades de aprendizaje. Conclu-sión: En las dificultades de aprendizaje se cometen más errores y se notan menos emparejamientos correctos en la tarea de emparejamiento, cuando hay límites en el tiempo de ejecución; de lo contrario, la disponibilidad de tiempo es compensatoria, reduciendo el número de inexactitudes. En las dificultades de aprendizaje, se necesita más tiempo para realizar la tarea de empareja-miento, debido al procesamiento más lento de la información; el tiempo que se consume en decodificar e identificar las correspondencias dígito-símbolo y la discriminación perceptiva no ocurre tan rápidamente como es necesario para la simultaneidad y automatización del acto.

Patrones de procesamiento sensorial de adultos con dificultades de aprendizaje autorreferidas / Sensory processing patterns of adults with self-reported learning disabilities

Resumen Las dificultades de aprendizaje, que pueden continuar manifestándose en la adultez, han mostrado vinculación con déficit en el procesamiento sensorial. El propósito de la investigación es indagar el perfil sensorial de adultos con y sin dificultades de aprendizaje (DA) en el área de lectoescritura. El estudio es cuantitativo no experimental. El perfil sensorial se evaluó a través de un cuestionario basado en el modelo de Dunn (1997b), que define cuatro patrones sensoriales a partir de la interacción entre el umbral neurológico y las estrategias de autorregulación, junto a un autorreporte de dificultades de aprendizaje. Los resultados mostraron puntuaciones similares en tres patrones sensoriales para ambos grupos, con diferencias significativas en el patrón sensorial de 'Espectador' (p = .038, d =0.5). Este patrón caracterizaría a adultos con DA con una tendencia a estrategias de autorregulación pasiva y umbral neurológico alto. Se concluye que las características de procesamiento sensorial pueden ser relevantes para orientar la intervención y apoyo de personas con DA. Se demuestra la relevancia de analizar el perfil de procesamiento sensorial para la comprensión de las dificultades de aprendizaje. En términos aplicados, amplía las posibilidades de apoyo para adultos con DA al visibilizar la necesidad de entornos que respondan a las características sensoriales individuales.

Abstract Learning difficulties, which may continue to manifest into adulthood, are linked to deficits in sensory processing. A study focused on investigating the sensory profile of adults with and without learning difficulties (LD) in literacy is presented. Quantitative and non-experimental study. The sensory profile was assessed through a questionnaire based on Dunn's model (1997b), which defines four sensory patterns based on the interaction between the neurological threshold and self-regulation strategies. We also included a self-reporting of LD. The results showed similar scores in three sensory patterns for both groups, with significant differences in the 'Bystander' sensory pattern (p = .038, d = 0.5). This pattern would characterize adults with LD with a tendency for passive self-regulation strategies and a high neurological threshold. Sensory processing characteristics may be relevant to guide the intervention and support of people with LD. Our findings demonstrate the relevance of analyzing the sensory processing profile for understanding learning difficulties. In applied terms, it expands support possibilities for adults with LD by highlighting the need for environments that respond to individual sensory characteristics.

Evidence of the adverse effects of air pollution on the population's health in Spain: analysis of the economic costs of premature deaths / Evidencias sobre los efectos adversos de la contaminación atmosférica en la salud de la población de España: análisis de los costes económicos de las muertes prematuras / Evidências sobre os efeitos adversos da poluição do ar sobre a saúde da população na Espanha: análise dos custos econômicos das mortes prematuras

Abstract: Exposure to ambient air pollution increases mortality and morbidity, leading disabilities, and premature deaths. Air pollution has been identified as a leading cause of global disease burden, especially in low- and middle-income countries in 2015 (Global Burden of Diseases, Injuries and Risk Factors Study, 2015). This study explores the relation between mortality rates and particulate matter (PM) concentrations in the 50 Spanish regions for the period 2002-2017. Moreover, we estimated the premature deaths due to PM in Spain according to welfare and production losses in 2017. Random-effects models were developed to evaluate the relation between mortality rates and PM concentrations. The economic cost of premature deaths was assessed using the Willingness to Pay approach to quantify welfare losses and the Human Capital method to estimate production losses. PM10 concentrations are positively related to mortality due to respiratory diseases and stroke. Based on 10,342 premature deaths in 2017, losses in welfare amount to EUR 36,227 million (3.1% of Spanish GDP). The economic value of current and future production losses reached EUR 229 million (0.02% of GDP). From a social perspective, air pollution is a public health concern that greatly impacts health and quality of life. Results highlight the need to implement or strengthen regulatory, fiscal, and health public policies to substantially benefit the population's health by reducing their exposure to air pollution.

Resumen: La exposición a la contaminación atmosférica aumenta la mortalidad y la morbilidad, lo que conduce a la discapacidad y a la muerte prematura. La contaminación del aire se identificó como una de las principales causas de la carga mundial de enfermedades, sobre todo en países de ingresos bajos y medianos en el 2015 (Global Burden of Diseases, Injuries and Risk Factors Study, 2015). Este artículo explora la relación entre las tasas de mortalidad y la concentración de material particulado (PM) en las 50 regiones españolas desde el 2002 hasta el 2017. Además, se realizó una estimación de las muertes prematuras provocadas por PM en España en términos de bienestar y pérdidas de producción en el 2017. Se desarrollaron modelos de efectos aleatorios para estudiar la relación entre las tasas de mortalidad y las concentraciones de PM. El costo económico de las muertes prematuras se evaluó usando el enfoque "disposición a pagar" para monetizar las pérdidas de bienestar y el método del capital humano para estimar las pérdidas de producción. Las concentraciones de PM10 están positivamente asociadas con la mortalidad por enfermedades respiratorias y accidente cerebrovascular. Con base en 10.342 muertes prematuras en el 2017, las pérdidas en el bienestar social ascendieron a EUR 36.227 millones (3,1% del PIB español). El valor económico de las pérdidas de producción presentes y futuras llegó a EUR 229 millones (0,02% del PIB). Desde un punto de vista social, la contaminación del aire es un problema de salud pública que tiene un gran impacto en la salud y en la calidad de vida. Los resultados ponen de manifiesto la necesidad de implementar o de fortalecer políticas públicas regulatorias, fiscales y de salud para obtener beneficios sustanciales para la salud con la reducción de la exposición.

Resumo: A exposição à poluição do ar ambiente aumenta a mortalidade e a morbidade, levando a incapacidades e mortes prematuras. A poluição do ar foi identificada como uma das principais causas da carga global de doenças, principalmente em países de baixa e média renda em 2015 (Global Burden of Diseases, Injuries and Risk Factors Study, 2015). Este artigo explora a relação entre as taxas de mortalidade e a concentração de material particulado (PM) nas 50 regiões espanholas de 2002 a 2017. Além disso, foi realizada uma estimativa das mortes prematuras causadas por PM na Espanha em termos de bem-estar e perdas de produção em 2017. Modelos de efeitos aleatórios foram desenvolvidos para estudar a relação entre as taxas de mortalidade e as concentrações de PMP. O custo econômico das mortes prematuras foi avaliado usando a abordagem "disposição a pagar" para monetizar as perdas de bem-estar e o método do capital humano para estimar as perdas de produção. As concentrações de PM10 estão positivamente associadas à mortalidade por doenças respiratórias e acidente vascular cerebral. Com base em 10.342 mortes prematuras em 2017, as perdas no bem-estar social subiram para EUR 36,227 bilhões (3,1% do PIB espanhol). O valor econômico das perdas de produção presentes e futuras atingiu os EUR 229 milhões (0,02% do PIB). Do ponto de vista social, a poluição do ar é um problema de saúde pública que tem grande impacto na saúde e na qualidade de vida. Os resultados evidenciam a necessidade de implementar ou fortalecer políticas públicas regulatórias, fiscais e de saúde para obter benefícios substanciais à saúde com a redução da exposição.

Saúde e queixa escolar: registros de conserv(ação) na conduta de psicólogos / Salud y queja escolar: registros de conserv(acción) en la conducta de los psicólogos / Health and school complaint: records of conserv(action) in the conduct of psychologists

RESUMO. Este artigo expõe a temática da conduta de profissionais da psicologia no campo da saúde, diante das demandas escolares. Resulta de uma pesquisa de Mestrado, cujo objetivo principal foi, com base na Psicologia Histórico-Cultural, identificar de que forma as práticas contemporâneas da psicologia na saúde explicitam a concepção dos profissionais ante os encaminhamentos e a função da escola para a constituição da subjetividade. Para tanto, foram analisados prontuários de crianças e adolescentes entre quatro e dezessete anos, encaminhados por queixa escolar a dois serviços públicos de saúde em um município de pequeno porte do interior paulista, durante o biênio 2014-2015, e efetivadas entrevistas com as/os psicólogas/os responsáveis nos diferentes serviços. Os resultados indicaram que a atividade da/o psicóloga/o, ao receber a demanda escolar, encontra-se pouco alterada em relação às condutas que vêm sendo adotadas no país, desde os anos de 1990. As práticas aderidas consistem, em grande maioria, no atendimento clínico individual ou grupal, que não envolve o ambiente escolar. Também se mantém o perfil das crianças encaminhadas e, no contexto da ciência psicológica aplicada à saúde, um distanciamento quanto ao conhecimento das implicações da educação escolar para a aprendizagem e o desenvolvimento humano, tanto quanto a importância do acesso aos bens culturais humanos, o que pode ser decisivo para as circunstâncias e para a qualidade do processo de humanização.

RESUMEN. Este artículo expone el tema de la conducta de los profesionales de la psicología en el campo de la salud, delante de las demandas escolares. Es el resultado de una investigación de maestría, cuyo objetivo principal era, basado en la psicología histórico-cultural, identificar cómo las prácticas contemporáneas de psicologia, en la salud, hacen explícito la concepción de los profesionales delante de las derivaciones y el papel de la escuela para el constitución de subjetividad. Con este fin, se analizaron los registros de salud de niños y adolescentes entre cuatro y diecisiete años, reenviados por queja escolar a dos servicios de salud pública en una pequeña ciudad del interior de São Paulo, durante el bienio 2014-2015, y efectivadas entrevistas con los psicólogos responsables em los diferentes servicios. Los resultados indicaron que la actividad del psicólogo, al recibir la demanda escolar, cambia poco en relación a las conductas que se han adoptado en el país, desde la década de los noventa. Las prácticas adheridas consisten, en su gran mayoría, en el cuidado clínico individual o grupal, que no involucra el ambiente escolar. El perfil de los niños referidos también se mantiene y, en el contexto de la ciencia psicológica aplicada a la salud, una distancia en cuanto al conocimiento de las implicaciones de la educación escolar para el aprendizaje y el desarrollo humano, así como la importancia del acceso a los bienes culturales humanos, que puede ser decisivo para las circunstancias y la calidad del proceso de humanización.

ABSTRACT. This article exposes the theme of the conduct of psychology professionals in the field of health, in view of school demands. It results from a Master's research, mainly aimed to, based on Historical-Cultural Psychology, identify how contemporary Psychology practices in health may explain the professionals' understanding about the referrals and the role of the school in building subjectivity. To this end, medical records of children and adolescents of four to seventeen years old were analyzed. Participants had been referred due to school complaint to two public healthcare services in a small municipality in São Paulo, in the biennium 2014-2015, and participated in interviews with the responsible psychologists in the services. The results indicated that the psychologist's activity when receiving the school demand has changed a little in relation to the conducts being adopted in the country since the 1990s. The practices adopted mainly consist in individual or group clinical care, disregarding the school environment. The profile of the children referred is also maintained and, in the context of psychological science applied to health, there is a distancing regarding the knowledge of the implications of school education on human learning and development, as well as the importance of accessing human cultural assets. This could be decisive for the circumstances and the quality of the humanization process.

Velocidad de procesamiento en escolares chilenos con y sin Trastorno por Déficit de Atención con Hiperactividad (TDAH) / Processing Speed in Chilean Schoolchildren With and Without Attention Deficit Hyperactivity Disorder (ADHD) / Velocidade de processamento em estudantes chilenos com e sem Transtorno de Déficit de Atenção e Hiperatividade (TDAH)

El TDAH es el trastorno del neurodesarrollo más diagnosticado en escolares. La evidencia indica que las funciones ejecutivas, como es el caso de la velocidad de procesamiento y la memoria de trabajo, están afectadas en estudiantes con TDAH, aunque no existe un acuerdo definitivo sobre su presencia sistemática en este trastorno. Esta investigación pretende determinar si la velocidad de procesamiento y la memoria de trabajo corresponden a variables cognitivas en el TDAH. Participaron 138 estudiantes de 10 a 17 años. Se determinó TDAH con la escala VADTRS; se evaluó velocidad de procesamiento con una tarea de rapidez grafomotora y memoria de trabajo con una tarea de dígitos. Se utilizó un diseño transversal, univariante e intersujeto para el análisis de los datos. El VADTRS detectó un grupo con TDAH (N = 97) y otro sin TDAH (N = 41). A ambos grupos se aplicaron tareas de velocidad de procesamiento y memoria de trabajo; los análisis permitieron detectar diferencias significativas en estas variables entre los grupos con y sin TDAH. El grupo con TDAH fue dividido según su presentación; no se detectaron diferencias significativas en velocidad de procesamiento; la memoria de trabajo mostró un rendimiento significativa- mente menor en las presentaciones de TDAH inatenta y combinada. La velocidad de procesamiento y la memoria de trabajo parecen distinguir entre sujetos con y sin TDAH, la velocidad de procesamiento no parece distinguir entre presentaciones y la memoria de trabajo aparece alterada en aquellas presentaciones en que el componente atencional es definitorio

ADHD is the most commonly diagnosed neurodevelopmental disorder in schoolchildren. Evidence indicates that executive functions, such as processing speed and working memory, are affected in students with ADHD, although there is no definitive agreement on their sys- tematic presence in this disorder. This research aims to determine whether processing speed and working memory correspond to cognitive variables in ADHD. A total of 138 students aged 10 to 17 years participated. ADHD was determined with the VADTRS scale; processing speed was assessed with a graphomotor speed task and working memory with a digit task. A cross-sectional, univariate, intersubject design was used for data analy- sis. The VADTRS detected one group with ADHD (N = 97) and one without ADHD (N = 41). Processing speed and working memory tasks were applied to both groups; analyses detected significant differences in these variables between the ADHD and non- ADHD groups. The ADHD group was divided according to presentation; no significant differences were detected in processing speed; working memory showed significantly lower performance in the inattentive and combined ADHD presentations. Processing speed and working memory appear to distinguish between subjects with and without ADHD, processing speed does not appear to distinguish between presentations, and working memory appears impaired in those presentations in which the attentional component is defining.

O TDAH é o distúrbio de desenvolvimento neurológico mais frequentemente diagnosticado em crianças em idade escolar. As provas indicam que as funções executivas, tais como a velocidade de processamento e a memória de trabalho, são afectadas nos estudantes com TDAH, embora não haja um acordo definitivo sobre a sua presença sistemática nesta doença. Esta investiga- ção visa determinar se a velocidade de processamento e a memória de trabalho correspondem a variáveis cognitivas na TDAH. Um total de 138 estudantes com idades compreendidas entre os 10 e os 17 anos participaram. A TDAH foi determinada com a escala VADTRS; a velocidade de processamento foi avaliada com uma tarefa de velocidade grafomotora e a memória de trabalho com uma tarefa de dígitos. Foi utilizado um desenho transversal, univariado e intersubjecto para análise de dados. O VADTRS detectou um grupo com ADHD (N = 97) e um grupo sem ADHD (N = 41). Ambos os grupos foram administrados com velocidade de processamento e tarefas de memória de trabalho; as análises detectaram diferenças significativas nestas variáveis entre os grupos com ADHD e sem ADHD. O grupo TDAH foi dividido de acordo com a apresentação; não foram detectadas diferenças significativas na velocidade de processamento; a memória de trabalho mostrou um desempenho significativamente inferior nas apresentações de TDAH desatenta e combinada. A velocidade de processamento e a memória de trabalho parecem distinguir entre assuntos com e sem TDAH; a velocidade de processamento não parece distinguir entre apresentações e memória de trabalho parece prejudicada nas apresentações em que a componente atencional está a definir
