Family Separation at the US and Mexico Border Continues.

Record-breaking levels of asylum seeking by families with young children continue at the United States/Mexico border, particularly the Rio Grande Valley sector. In this Commentary, our aim is to increase awareness by providing child and adolescent mental health care providers with an update on current migrant conditions, bringing to light issues of family separation previously highlighted in the Journal.1 For context, our international group has collected data, via 3 large-scale studies funded by the National Institutes of Health, from more than 600 Latinx immigrants seeking asylum at the US/Mexico border in the last 4 years, during which levels of violence, climate disruption, and poverty in the Northern Triangle of Central America (ie, El Salvador, Guatemala, and Honduras) and Mexico have propelled high and sustained levels of asylum seeking in the United States. We contribute expertise in clinical psychology, Latinx psychology, attachment disruption, and public health, as well as this front-row perspective.

First principles study on the potential of functionalized porous silicon to capture adverse agents to human health: The role played by the interface interactions.

Porous Silicon (PSi) is an ideal material to build biosensors due to its large surface area and biocompatibility. However, it lacks of selectivity. By adhering bilayer lipids, active sites are added for vital biochemical processes. Such processes are promoted by different proteins, which aid to detect pollutants and drugs, among other. The present work is a systematic theoretical study at the density functional theory level on PSi models, functionalized with H and OH. Several concentrations of such functional groups were assessed at the pores to elucidate the reactivity via Fukui indexes of electrophilic and nucleophilic attack. The 1,2-dimyristoyl-sn-glycero-3-phosphocholine(DMPC) lipid was used as a probe system to interact with the PSi. The attraction was evaluated as electrostatic with a van der Waals contribution. The adsorption was highly selective to the degree of functionalization at the pore. The PSi facets (100) and (001) showed different mechanisms of interaction with the DMPC lipid. The theoretical absorption spectra addressed that the DMPC lipid could be identified with intensity variations coming from the degree of functionalization at the pore, which may be further rationalized experimentally. The present methodology may aid to tailor novel materials to capture and identify adverse agents present in the environment.

Alteración de la mineralización de tejidos dentarios y paradentarios inducida por bifosfonatos en ratas Wistar / Alteration of mineralization of dental and paradental tissues induced by biphosphonates in Wistar rats

Desórdenes sistémicos de la homeostasis mineral o fallas en la mineralización de la matriz extracelular pueden afectar tanto a las piezas dentarias como a su aparato de sostén, conduciendo al fracaso de los tratamientos odontológicos. Existe poca evidencia científica sobre modelos animales que permitan es-tudiar la respuesta de tejidos dentarios/paradenta-rios frente a este tipo de desórdenes. El objetivo del presente trabajo fue estudiar experimentalmente al-teraciones de la biomineralización inducidas por bis-fosfonatos en ratas Wistar. Para ello, 20 ratas Wistar hembras y machos (35±10 g) fueron tratados con 20 mg/kg de etidronato bisódico (EHBP) o solución fi-siológica (control) vía intraperitoneal 5 veces por se-mana durante 3 semanas. Luego de la eutanasia, se extrajeron las mandíbulas para su procesamiento y análisis histológico (H&E). Mediante microfotografías digitales se evaluó: área ósea/área total, espesor de ligamento periodontal, áreas de dentina y de cemen-to. Los resultados se analizaron estadísticamente mediante el test T de Student para comparaciones entre grupos y el test ANOVA de 2 vías para las com-paraciones intersexo. Los grupos EHBP presentaron mayor proporción de osteoide, dentina y cemento no mineralizados respecto a los controles, siendo más marcadas las diferencias en las hembras. Las hem-bras del grupo EHBP mostraron una disminución significativa en el espesor del ligamento periodontal respecto de los controles, aunque esta tendencia no se observó en machos. Los resultados del presente estudio demuestran que el EHBP, en la dosis y tiempo estudiados, altera los procesos de biomineralización tanto del tejido óseo como de los tejidos dentarios (AU)

Systemic disorders of mineral homeostasis or alterations in the mineralization of the extracellular matrix can affect both dental and supportive tissues, leading to the failure of dental treatments. There is a lack of scientific information about animal models that allow to study the response of dental/paradental tissues in this type of disorders. The aim of the present work was to study the biomineralization alterations induced by bisphosphonates in Wistar rats and to study the response of dental and paradental tissues. Twenty Wistar rats (35±10 g) were divided in control (females, males) and EHBP (females, males) groups. The EHBP group received 20 mg/kg of ethidronate bisodium intraperitoneally 5 times a week for 3 weeks, while the control group received saline solution. After euthanasia, mandibles were resected and processed histologically to obtained oriented sections for H&E staining. Photomicrographs were used to evaluate: Bone area/total area, periodontal ligament thickness, dentin and cement area. Results were statistically analyzed using the Student's T test for comparisons between groups and the 2-way ANOVA test for male and female comparisons. The EHBP groups showed a higher amount of non-mineralized osteoid, dentin and cement compared to control groups, being more evident in females. Females in the EHBP group showed a significant decrease in periodontal ligament thickness compared to controls, although this profile was not observed in males. The results of the present study demonstrate that EHBP, at the dose and time studied, alters the biomineralization processes of both bone and dental tissues (AU)

Cuestionario de reserva cognitiva: análisis psicométrico desde la teoría de respuesta al ítem / Cognitive Reserve Questionnaire: psychometric analysis from the item response theory

Introducción: La reserva cognitiva es la capacidad para tolerar mejor el daño cerebral mediante recursos cognitivos preexistentes y compensatorios. Un método de evaluación es el cuestionario de reserva cognitiva (CRC) de Rami. El objetivo fue realizar un análisis de la calidad informativa del CRC desde la teoría de respuesta al ítem (TRI), con el fin de aportar datos más precisos sobre la fiabilidad de consistencia interna. Se probó, además, la validez convergente con medidas de atención, memoria de trabajo y fluidez. Sujetos y métodos: Participaron 210 argentinos de población general (media edad, 66,8 años). El CRC se administró junto con el test de dígitos y tres tareas de fluidez. Se ajustó un modelo de respuesta graduada desde la TRI con estimación de parámetros de discriminación (a) y dificultad (b), y se elaboró una curva de información del CRC. Se efectuaron correlaciones bivariadas y parciales. Resultados: La TRI indicó una alta discriminación para los ítems del CRC ‘Escolaridad’ y ‘Nivel de ocupación’ (tanto para la versión de ocho ítems como para la versión de seis ítems). En el CRC de ocho ítems se obtuvo una baja discriminación para ‘Formación musical’ y ‘Juegos intelectuales’. En ambas versiones del CRC, la curva indica mayor valor informacional a bajo nivel del constructo. Hubo correlación con el test de dígitos y con las tareas de fluidez, incluso al controlar por edad. Conclusiones: El presente estudio es el primer análisis del CRC desde la TRI, que concluye que el instrumento resulta más confiable cuando se aplica a sujetos con menor reserva. El CRC posee aceptable validez convergente.(AU)

INTRODUCTION: Cognitive reserve is the ability to better tolerate brain damage through pre-existing and compensatory cognitive resources. One assessment method is the Rami CRQ-Cognitive Reserve Questionnaire. The objective was to carry out an analysis of the informative quality of the CRQ from the item response theory (IRT), in order to provide more precise data on the reliability of internal consistency. Convergent validity was also tested with measures of attention, working memory, and fluency. SUBJECTS AND METHODS: 210 Argentines from the general population (mean age, 66.8 years) participated. The CRQ was administered together with the digits test and three fluency tasks. A graded response model was fitted from IRT with estimation of discrimination parameters (a) and difficulty (b), and a CRQ information curve was created. Bivariate and partial correlations were made. RESULTS: The IRT indicated high discrimination for the CRQ items ‘Education’ and ‘Occupation level’ (both for the 8-item version and the 6-item version). In the CRQ of 8 items, low discrimination was obtained for ‘Musical training’ and ‘Intellectual games’. In both versions of the CRQ, the curve indicates greater informational value at a low level of the construct. There was a correlation with the digits test and with fluency tasks, even when controlling for age. CONCLUSIONS: This study is the first analysis of CRQ from IRT, concluding that the instrument is more reliable when applied to subjects with less reserve. The CRQ has acceptable convergent validity.(AU)

Determinantes socioeconómicos y sociodemográficos asociados al consumo de frutas y verduras de las madres de familia y los hogares de escolares de Jalisco / Socioeconomic and sociodemographic determinants associated with fruit and vegetable consumption among mothers and homes of schoolchildren in Jalisco

Introducción: incrementar el consumo de frutas y verduras es una prioridad, objetivo fundamental en las políticas públicas a nivel mundial. Dado que dicho consumo en los escolares de Jalisco (México) se encuentra por debajo de las recomendaciones alimentarias, es esencial identificar los determinantes que influyen en su consumo de frutas y verduras, para promover el desarrollo de acciones que contribuyan a mejorarlo. Objetivo: identificar los determinantes socioeconómicos y sociodemográficos del consumo de frutas y verduras en las madres de familia y los hogares de escolares de Jalisco, México. Método: estudio transversal analítico, realizado durante el primer trimestre del año 2020 utilizando una frecuencia de consumo de alimentos validada y un cuestionario sobre factores sociodemográficos y socioeconómicos. Resultados: el bajo nivel educativo de las madres de los escolares se asoció con un menor consumo de verduras y el bajo nivel de ingresos en el hogar se asoció con un menor consumo de frutas por los escolares. Conclusiones: el bajo nivel educativo de las madres y el bajo nivel de ingresos de los hogares fueron determinantes asociados al consumo de frutas y verduras de los escolares. Sin embargo, se presentaron diferencias en cuanto a los determinantes para las frutas y para las verduras. Estos factores y sus diferencias deben de tenerse en cuenta para la planificación de acciones que contribuyan a mejorar la ingesta de frutas y verduras en la población escolar (AU)

Introduction: increasing fruit and vegetable consumption is a priority. It has been prioritized as a fundamental objective of public policies worldwide. Given that such consumption in schoolchildren in Jalisco (Mexico) is below the dietary recommendations it is crucial to identify the determinants that influence this consumption to promote the development of contextualized actions that improve it. Objective: to identify the socioeconomic and sociodemographic determinants of fruit and vegetable consumption among mothers and households of schoolchildren in Jalisco, Mexico. Method: an analytical, cross-sectional study carried out during the first quarter of 2020. A validated food consumption frequency and a questionnaire on sociodemographic and socioeconomic factors were used for its development. Results: a lower educational level of the mothers of schoolchildren was associated with a lower consumption of vegetables by schoolchildren. In turn, a lower household income level was associated with a lower consumption of fruits in schoolchildren. Conclusions: a low educational level of mothers and a low household income were determinants associated with fruit and vegetable consumption in schoolchildren. However, there were differences in the determinants for fruits and vegetables. It is essential to consider these factors and their differences in order to plan actions that contribute to improving fruit and vegetable intake in the school population (AU)

[Validation of an ophtalmology tele-expertise protocol in nursing homes]. / Validation d'un protocole de téléexpertise d'ophtalmologie en EHPAD.

INTRODUCTION: Assisted living residents are a fragile population with limited access to health care. In recent years, telemedicine has developed in several specialties, including ophthalmology. The main objective of our study is the validation of an ophthalmology telemedicine protocol in assisted living facilities. MATERIALS AND METHODS: This is a retrospective, multicentric, descriptive study including 4 assisted living facilities in the Rennes area. An ophthalmic technician examined residents for one half-day per week. The examination was performed directly in the patient's room, in bed or in a chair, with portable equipment. An ophthalmologist from our service interpreted the results remotely on a deferred basis within 7 days. Appropriate medical or surgical care was then offered to the patient depending on the diagnosis. RESULTS: We included 113 residents. A complete, interpretable examination was achieved in 84.1% of cases. One or more ophthalmic conditions were diagnosed in 57.5% of the residents. Of the residents who were then seen at the university medical center, 65% underwent a scheduled surgical procedure or laser. Visual acuity was significantly improved subsequent to the telemedicine encounter. DISCUSSION: The success rate of a complete, interpretable examination allows us to now validate our nursing home examination procedure. In addition to bringing a large amount of initially unknown information to the medical and paramedical staff of the structure, ophthalmology telemedicine allows for a significant improvement in visual acuity. CONCLUSION: This project validated the feasibility of ophthalmology telemedicine in an assisted living setting. This protocol may also be applicable to other health care settings (penitentiaries, mental health institutions, etc.).

[Cognitive reserve questionnaire: the psychometric properties in an Argentinian population]. / Cuestionario de reserva cognitiva: propiedades psicométricas en población argentina.

INTRODUCTION: Cognitive reserve is the brain's capacity to actively overcome damage by means of pre-existing cognitive resources and compensatory processes. This capacity is enhanced by education, occupational attainment, learning languages and the habit of reading, among other important factors. This study aimed to investigate the psychometric properties of Rami et al's Cognitive Reserve Questionnaire in an Argentinian population. MATERIALS AND METHODS: The sample that participated in the study comprised 203 Argentinian adult volunteers from the general population (mean age, 66.1; standard deviation, 8.1). The Cognitive Reserve Questionnaire was administered together with the Montreal Cognitive Assessment. Confirmatory factor analysis was carried out to test the unidimensionality of the questionnaire. In addition, reliability was estimated by the categorical omega coefficient and associative validity was analysed by means of bivariate correlations. RESULTS: Factor analysis confirms the unidimensionality of the questionnaire with good fit indices. Items 5 (musical training) and 8 (intellectual games), however, show low factor loadings. The test has acceptable reliability, with a categorical omega coefficient = 0.72, although it should be noted that the average variance extracted (0.41) is below the recommended criterion of 0.5. Good associative validity is observed: r (200) = 0.4; p < 0.001. CONCLUSIONS: The Cognitive Reserve Questionnaire is an instrument with acceptable psychometric properties for use in an Argentinian population. More research is required to further investigate the low factor loadings of items 5 and 8 and to strengthen the evidence of reliability.

Además, se estimó la confiabilidad por el coeficiente omega categórico y se analizó la validez asociativa mediante correlaciones bivariadas. Resultados: El análisis factorial confirma la unidimensionalidad del cuestionario con buenos índices de ajuste. Sin embargo, los ítems 5 (formación musical) y 8 (juegos intelectuales) presentan baja carga factorial. La prueba posee una aceptable confiabilidad, con un coeficiente omega categórico = 0,72, aunque cabe advertir que la varianza extraída promedio (0,41) se ubica por debajo del criterio recomendado de 0,5. Se observa una buena validez asociativa –r (200) = 0,4; p < 0,001–. Conclusiones: El Cuestionario de Reserva Cognitiva es un instrumento con aceptables propiedades psicométricas para su uso en población argentina. Serán convenientes nuevas investigaciones que profundicen en la baja carga factorial de los ítems 5 y 8 y refuercen las evidencias de fiabilidad.(AU)

Introduction: Cognitive reserve is the brain’s capacity to actively overcome damage by means of pre-existing cognitive resources and compensatory processes. This capacity is enhanced by education, occupational attainment, learning languages and the habit of reading, among other important factors. This study aimed to investigate the psychometric properties of Rami et al’s Cognitive Reserve Questionnaire in an Argentinian population. Materials and methods: The sample that participated in the study comprised 203 Argentinian adult volunteers from the general population (mean age, 66.1; standard deviation, 8.1). The Cognitive Reserve Questionnaire was administered together with the Montreal Cognitive Assessment. Confirmatory factor analysis was carried out to test the unidimensionality of the questionnaire. In addition, reliability was estimated by the categorical omega coefficient and associative validity was analysed by means of bivariate correlations. Results: Factor analysis confirms the unidimensionality of the questionnaire with good fit indices. Items 5 (musical training) and 8 (intellectual games), however, show low factor loadings. The test has acceptable reliability, with a categorical omega coefficient = 0.72, although it should be noted that the average variance extracted (0.41) is below the recommended criterion of 0.5. Good associative validity is observed: r (200) = 0.4; p < 0.001. Conclusions: The Cognitive Reserve Questionnaire is an instrument with acceptable psychometric properties for use in an Argentinian population. More research is required to further investigate the low factor loadings of items 5 and 8 and to strengthen the evidence of reliability.
