Abstract Ovine pulmonary adenocarcinoma is a transmissible pulmonary malignancy of sheep caused by a beta-retrovirus currently named Jaagsiekte sheep retrovirus (JSRV). Club cells (formerly Clara cells) in the bronchiole and type II pneumonocytes in the alveoli are the target oncogenic cells for this virus. Characterized clinically by intermittent cough, abundant nasal discharge, and progressive weight loss, the tumors randomly involve all lung lobes or have a cranioventral distribution mimicking bronchopneumonia. The definitive diagnosis of ovine pulmonary adenocarcinoma requires identifying Jaagsiekte sheep retrovirus or associated specific proteins in neoplastic cells such as JSRV-Env oncogenic protein. A two-year-old Male Pelibuey sheep with a history of chronic cough and progressive weight loss was treated unsuccessfully with antibiotics and died a few days later. Postmortem examination revealed lung edema and several nodular to locally extensive masses in the lungs. Microscopically the tumoral tissues were composed of clusters of neoplastic epithelial cells exhibiting a lepidic growth pattern typical of pulmonary carcinoma. Tumoral cells were immunopositive for Jaagsiekte sheep retrovirus-Env oncogenic protein. Based on these findings, the final diagnosis of ovine pulmonary adenocarcinoma was made.

Resumen El adenocarcinoma pulmonar ovino es una neoplasia pulmonar transmisible del ganado ovino causada por un beta retrovirus actualmente denominado retrovirus Jaagsiekte de las ovejas (JSRV). Las células Club (anteriormente llamadas células de Clara) de los bronquiolos y los neumocitos de tipo II de los alvéolos son las células oncogénicas que constituyen el objetivo de este virus. Se caracteriza clínicamente por tos intermitente, secreción nasal abundante y pérdida de peso progresiva, los tumores afectan aleatoriamente a todos los lóbulos pulmonares o tienen una distribución cráneo-ventral que simula una bronconeumonía. El diagnóstico definitivo del adenocarcinoma pulmonar ovino requiere que se identifique el retrovirus Jaagsiekte de las ovejas RVJO-Env, o bien, la presencia de proteínas específicas asociadas en las células neoplásicas, tales como la proteína oncogénica JSRV-Env. Un ovino Pelibuey macho de dos años con un historial de tos crónica y pérdida de peso progresiva fue tratado sin éxito con antibióticos y murió unos días más tarde. El examen post mortem reveló edema pulmonar y varias masas nodulares localmente extensas en los pulmones. A nivel microscópico, los tejidos tumorales estaban compuestos por grupos de células epiteliales neoplásicas que mostraban un patrón de crecimiento lepídico típico del carcinoma pulmonar. Las células tumorales fueron inmunopositivas para la proteína oncogénica Env del retrovirus Jaagsiekte de la oveja. Con base en estos hallazgos, se hizo el diagnóstico final de adenocarcinoma pulmonar ovino.

Resumen Antecedentes: La displasia del desarrollo de la cadera (DDC) constituye una entidad clínica compleja que suele ser infradiagnosticada que, de no ser precozmente detectadas y manejadas, convertirán al individuo afectado en un ser discapacitado, con efecto negativo social, económico y emocional. Objetivo: Determinar la capacidad para la detección radiográfica oportuna de la DDC antes y después de una intervención educativa en médicos residentes de medicina familiar. Método: Se realizó una intervención educativa en residentes de medicina familiar, en la que se les dio capacitación sobre detección de DDC en proyecciones radiográficas. Se realizó una evaluación previa y posterior a la capacitación. El análisis estadístico se realizó mediante pruebas t de Student y χ2, tomando como significativo un valor de p ≤ 0.05. Resultados: Participaron 94 residentes. El 87.2% dijeron no conocer el protocolo radiológico de detección. En la evaluación preintervención, el 87.2% no tenían conocimiento del protocolo (p = 0.525). Se observó que el 98.9% trazaron de manera incorrecta la línea de Perkins (p = 0.427), el 96.8% la línea de Hilgenreiner (p = 0.177) y el 87.2% no consideraron los datos de displasia bilateral (p = 0.956). Posterior a la intervención educativa, el 87.2% trazaron de manera correcta la línea de Perkins (p = 0.926), el 97.8% la línea de Hilgenreiner (p = 0.325) y el 78.7% sí consideró los datos de displasia bilateral (p = 0.826). Conclusiones: Tras la capacitación, el 80% de los médicos residentes de medicina familiar fueron capaces de detectar oportunamente la DDC.

Abstract Background: Developmental dysplasia of the hip (DDH) is a complex clinical entity that is usually underdiagnosed, if not detected and managed early, will turn the affected individual into a disabled being, with negative social, economic and emotional effects. Objective: To determine the capacity for the timely radiographic detection of DDH before and after an educational intervention. Method: An educational intervention is carried out in family medicine resident, where they are given training on detection in DDH radiographic projections. Pre- and post-training evaluation is carried out. Statistical analysis is performed using Student's t and χ2, taking p ≤ 0.05 as significant. Results: 94 residents participated. In the pre-intervention evaluation, 87.2% had no knowledge of the early detection protocol (p = 0.525). It was observed that 98.9% incorrectly drew the Perkins line (p = 0.427), 96.8% the Hilgenreiner line (p = 0.177) and 87.2% did not consider the data of bilateral dysplasia (p = 0.956). After the educational intervention, 87.2% correctly drew the Perkins line (p = 0.926), 97.8% the Hilgenreiner line (p = 0.325) and 78.7% if they considered the data of bilateral dysplasia (p = 0.826). Conclusions: After this training, 80% of family medicine residents were able to detect DDH in a timely manner.

Abstract This article seeks to identify and discuss evidence-informed options to address the judicialization of health. The Supporting Policy Relevant Reviews and Trials Tools were used to define the problem and the search strategy, which was carried out in the following databases: PubMed, Health Systems Evidence, Campbell, Cochrane Collaboration, Rx for Change Database, and PDQ-Evidence. Selection and assessment of methodological quality was performed by two independent reviewers. The results were presented in a narrative synthesis. This study selected 19 systematic reviews that pointed out four strategies to address the judicialization of health in Brazil: 1) Rapid response service, 2) Continuous education program, 3) Mediation service between the parties involved, and 4) Adoption of a computer-based, online decision-making support tool and patient-mediated interventions. This study therefore presented and characterized four options that can be considered to address the judicialization of health. The implementation of these options must ensure the participation of different actors, reflecting on different contexts and the impact on the health system. The availability of human and financial resources and the training of teams are critical points for the successful implementation of the options.

ABSTRACT Several studies have evidenced that children in out-of-home care (OOHC), including foster family care and residential care, reveal high levels of mental health disorders (ranging from 40% to 88%). This study examines the outcomes in mental health reported by key residential workers in a group of children and youth (N = 492) between 8-17 years old who were in residential child care (RCC) in Spain. The research also aims to explore the relationship between mental health outcomes and the provision of mental health services (i.e., receiving any mental health treatment) as well as the influence of child, family, and placement factors. The design of this study includes two measures: a baseline (T1) and a follow-up two years later (T2). The results indicated that 29.9% of young people enjoyed sustained mental health; 26% meaningful improvement in their mental health; 23.5% meaningful deterioration; and the remaining 20.5% showed no meaningful change. One of the main findings was that receiving mental health treatment had a significant impact on mental health outcomes. It is crucial to establish protocols and systematic detection tools to assess mental health and ensure detection and referral to proper treatment.

RESUMEN La investigación en el ámbito de la protección a la infancia ha destacado la presencia de un alto porcentaje de niños, niñas y adolescentes (NNA) en acogimiento residencial y familiar con trastornos de salud mental (entre el 40% y el 88%). Este estudio tiene como objetivo examinar los cambios experimentados en la salud mental de los NNA durante el proceso de acogida según informan sus educadores de referencia en un grupo de 492 NNA entre 8-17 años que se encontraban en hogares de protección en España. El estudio también tiene como objetivo explorar la relación entre los resultados en salud mental y el tratamiento recibido desde diferentes servicios de salud mental, además de la influencia que puedan ejercer factores del NNA, su familia o el proceso de protección. El diseño del estudio se basa en dos medidas: línea base (T1) y seguimiento dos años después (T2). Los resultados indican que el 29.9% de los NNA mantenía una buena salud mental en las dos medidas, 26% manifestaron una mejora significativa partiendo de niveles clínicos, 23.5% manifestaron un deterioro significativo y el 20.5% no mostraron cambios significativos, manteniendo niveles clínicos en ambas medidas. Una de las principales conclusiones fue que estar recibiendo o no tratamiento en salud mental resultó ser un factor clave en la evolución de los NNA. Por tanto, resulta crucial establecer sistemas de detección de problemas de salud mental en esta población con el fin de derivar precozmente a tratamientos adecuados.

Abstract Brown lacewings have a cosmopolitan distribution and stand out for their entomophagous habits on small, soft-bodied prey. In Mexico, the species Sympherobius barberi (Banks, 1903) is recorded from Baja California, Estado de Mexico, Guanajuato, and Morelos. Interest in its potential commercial use as a biological control agent in the country motivated the review of this species. Both in scientific publications and in databases and biological collections, the taxonomic characters required to determine this species are documented, proposing to replace the basic taxonomy based on wing spot patterns. In addition, new information on prey and host plants is recorded: Brevicoryne brassicae (Linnaeus, 1758) in Brassica spp.; Dactylopius confusus (Cockerell, 1893) in various species of Opuntia y Nopalea cochenillifera; Dactylopius opuntiae in Opuntia ficus-indica; Phenacoccus solenopsis Tinsley, 1898 in cotton; Planococcus ficus Signoret, 1875 in grapevine; and larvae of Plutella xylostella (Linnaeus, 1758) in broccoli.

Resumen Los hemeróbidos tienen una distribución cosmopolita y destacan por sus hábitos entomófagos sobre insectos pequeños de cuerpo blando. En México, la especie Sympherobius barberi (Banks, 1903) se registra en Baja California, Estado de México Guanajuato, y Morelos. El interés sobre su potencial uso comercial como agente de control biológico en el país motivó la revisión de esta especie. Tanto en publicaciones científicas como en bases de datos y colecciones biológicas, se documentan los caracteres taxonómicos requeridos para determinar esta especie y se propone sustituir la taxonomía básica basada en patrones de manchas alares. Además, se reporta nueva información sobre presas y plantas hospederas: Brevicoryne brassicae (Linnaeus, 1758) en Brassica spp.; Dactylopius confusus (Cockerell, 1893) en varias especies del género Opuntia y Nopalea cochenillifera; Dactylopius opuntiae (Cockerell, 1896) sobre Opuntia ficus-indica; Phenacoccus solenopsis Tinsley, 1898 en algodón; Planococcus ficus Signoret, 1875 en vid; y larvas de Plutella xylostella (Linnaeus, 1758) en brócoli.

Abstract Introduction The World Health Organization (WHO) recommends exclusive breastfeeding up to the 6th month of life of the child and its maintenance with complementary feeding until at least 2 years of age. Despite its importance, the intake of breast milk substitutes is highly prevalent and a public health concern. Objective To evaluate the association between the types of milk ingested and nutritional status in the first year of life. Method Observational longitudinal study with Brazilian children from a multicentric study. At 3, 6, 9, and 12 months of age, the types of milk consumed were investigated using a food frequency questionnaire (FFQ), and anthropometric measurements were performed. Crude and adjusted associations were assessed by linear regression. Results Of the 2,965 pairs of mothers-babies screened, 362 met the criteria and accepted to participate in the study (50% of boys). At 12 months of age, higher weight-for-age and weight-for-length z-scores were observed in boys who consumed only formula or only cow's milk, compared to boys who consumed only breast milk. Higher length-for-age z-scores were found among girls who consumed only formula or only cow's milk at 9 and 12 months, compared to girls who consumed only breast milk at the same ages. Conclusion The types of milk consumed were associated with nutritional status during the first year of life, with differences between boys and girls. The higher anthropometric indexes in children who did not receive breastmilk call our attention to the persistence of such deviations toward excessive weight status in the future.

Resumo Introdução A Organização Mundial da Saúde (OMS) recomenda o aleitamento materno exclusivo até o 6º mês de vida da criança e a sua manutenção com alimentação complementar até pelo menos os 2 anos de idade. Apesar da sua importância, a ingestão de substitutos do leite materno é altamente prevalente, sendo uma preocupação em saúde pública. Objetivo Avaliar a associação entre os tipos de leite ingeridos e o estado nutricional no primeiro ano de vida. Método Estudo longitudinal observacional com crianças brasileiras pertencentes a um estudo multicêntrico. Aos 3, 6, 9 e 12 meses de idade foram investigados os tipos de leite consumidos por meio de questionário de frequência alimentar (QFA) e foi realizada antropometria. As associações brutas e ajustadas foram avaliadas por intermédio de regressão linear. Resultados Das 2.965 duplas de mães-bebês rastreadas, 362 atenderam aos critérios e aceitaram participar do estudo (50% meninos). Aos 12 meses de idade, os maiores escores-z de peso para idade e de peso para comprimento foram observados nos meninos que consumiam apenas fórmula ou apenas leite de vaca. Os maiores escores-z de comprimento para idade foram encontrados entre as meninas que ingeriam apenas fórmula ou apenas leite de vaca aos 9 e 12 meses. Ambos foram comparados àqueles que ingeriam apenas leite materno nas mesmas idades. Conclusão Os tipos de leite consumidos associaram-se ao estado nutricional no primeiro ano de vida, sendo observadas diferenças entre os sexos. Os maiores índices antropométricos nas crianças que não recebiam leite materno chamam a atenção para a persistência futura desses desvios, em direção ao excesso de peso.

Viannaia sp., Sarcocystis sp., Mathevotaenia sp. e Trichostrongylidae causaram enterite mucosa eosinofílica difusa. Cruzia sp. e Trichuris didelphis causaram tiflite mucosa eosinofílica difusa. Cistos de Sarcocystis spp. foram detectados no citoplasma das fibras musculares, sem alterações histológicas.

Resumen: El cultivo del ñame es de alta importancia para la seguridad alimentaria de las familias rurales en la región Caribe de Colombia. Uno de los principales problemas tecnológicos que enfrentan los pequeños productores es la baja calidad y disponibilidad de la semilla para las siembras. El presente trabajo se realizó con el objeto de evaluar la tecnología de producción de minitubérculos en plántulas de ñame generadas a partir de esquejes, mediante inducción con rizobacterias. Para ello, inicialmente se evaluó in vitro la capacidad de producción de fitohormonas de tres rizobacterias, identificadas con los códigos DCR11 (Azotobacter vinelandii), DSC21 (Brevibacillus laterosporus) y DSC1 (Bacillus licheniformis), y una vez comprobada su capacidad, se estableció un experimento bajo condiciones de casa de malla para inducir, con las rizobacterias, la producción de minitubérculos en las plántulas de ñame, bajo tres niveles de sombreamiento. Se utilizó un diseño experimental completamente al azar con arreglo en parcelas subdivididas y tres repeticiones, en donde la parcela principal correspondió a los niveles de sobreamiento (0, 65 y 80%), las subparcelas a las tres rizobacterias (DCR11 A. vinelandii, DSC1 B. licheniformis, DSC21 B. laterosporus) y las sub-subparcelas a las dosis del inóculo (0, 2, 4 y 6 mL pl-1). Los resultados in vitro demostraron el potencial de las rizobacterias para producir citoquinas y auxinas. En casa de malla se logró evidenciar la capacidad de producción de minitubérculos por parte de las plántulas de ñame, en donde las rizobacterias DSC1 B. licheniformis y DSC21 B. laterosporus mostraron mayor capacidad de inducción. A partir de los resultados se demostró la viabilidad de producción de minitubérculos en plántulas de ñame bajo condiciones de casa de malla mediante inducción con rizobacterias, por lo que se recomendó su validación a nivel semicomercial como estrategia para la producción masiva de minitubérculos de ñame, como alternativa para la siembra de cultivos comerciales.

Summary: Yam cultivation is of high importance for the food security of rural families in the Caribbean region of Colombia. One of the main technological problems faced by small yam producers is the low quality and availability of seed for planting. The present work was carried out to evaluate the technology of minitubers production in yam seedlings generated from cuttings, by induction with rhizobacteria. For this purpose, the phytohormone production capacity of three rhizobacteria, identified with the codes DCR11 (Azotobacter vinelandii), DSC21 (Brevibacillus laterosporus), and DSC1 (Bacillus licheniformis), was initially evaluated in vitro, and once their capacity was verified, an experiment was established under mesh house conditions to induce, with rhizobacteria, the production of mini-tubers in yam seedlings under three levels of shading. A completely randomized experimental design with subdivided plots and three replications was used, where the main plot corresponded to the shade levels (0, 65 and 80%), the subplots to the rhizobacteria (DCR11 A. vinelandii, DSC1 B. licheniformis, DSC21 B. laterosporus), and the sub-subplots at the inoculum doses (0, 2, 4 and 6 mL pl-1). The in vitro results demonstrated the potential of rhizobacteria to produce cytokines and auxins. In mesh house, the capacity of yam seedlings to produce mini-tubers was demonstrated, where the rhizobacteria DSC1 B. licheniformis and DSC21 B. laterosporus showed greater induction capacity. The results demonstrated the feasibility of minitubers production in yam seedlings under mesh house conditions by induction with rhizobacteria, and therefore, its validation at a semi-commercial level is recommended as a strategy for mass production of yam minitubers, as an alternative for the planting of commercial crops.

Resumen: Introducción: La teoría de la autodeterminación representa un marco para comprender los factores que facilitan la motivación académica, constructo relevante para los contextos educativos. Uno de los instrumentos más utilizados para medir el constructo es el cuestionario de autorregulación académica (SRQ-A), pero se carece de antecedentes psicométricos sobre la evaluación de este modelo de medida en su versión en español. Objetivo: Evaluar la estructura factorial, consistencia interna y validez del cuestionario de autorregulación académica (SQR-A) en una muestra de estudiantes universitarios chilenos. Método: Los participantes fueron 808 estudiantes de dos universidades chilenas. El modelo de medida se evaluó mediante análisis factorial confirmatorio (AFC). La validez y confiabilidad se evaluaron mediante la varianza media extraída y la fiabilidad compuesta. Resultados: Los resultados muestran que el modelo de medida de cuatro factores presenta niveles de ajuste adecuados, además de niveles adecuados de validez y consistencia interna. Conclusión: La versión en español del SQR-A constituye una medida útil para ser aplicada en contextos de educación superior.

Abstract: Introduction: The self-determination theory represents a framework to understand the factors that facilitate academic motivation, a relevant construct for educational contexts. One of the most used instruments to measure the construct is the Academic Self-Regulation Questionnaire (SQR-A), but there is a lack of psychometric background on the assessment of this measurement model of the Spanish version. Objective: To assess the factorial structure, internal consistency, and validity of the Academic Self-Regulation Questionnaire (SQR-A), in a sample of Chilean university students. Method: The participants were 808 students from two Chilean universities. The measurement model was evaluated using confirmatory factor analysis (CFA). The validity and reliability were assessed using mean-variance extracted and composite reliability. Results: The results show that the four-factor measurement model shows adequate levels of fit, in addition to adequate levels of validity and internal consistency. Conclusion: The Spanish version of the SRQ-A is a useful measure to be applied in higher education contexts.

Resumen: Los programas de simulación térmica de edificios (BTS) se utilizan cada vez más para evaluar el confort térmico de los ocupantes y el consumo de energía del edificio. Aunque algunos autores han señalado que no tener en cuenta la masa térmica de los componentes del edificio da como resultado predicciones de comportamiento erróneas, algunos usuarios de BTS, estándares y sistemas de clasificación de edificios aún no consideran la masa térmica. La cuantificación de la diferencia en las predicciones cuando se considera la masa térmica (M) o se ignora (NM) se ha reportado en la literatura para edificios con aire acondicionado (AC). En este trabajo se realiza la cuantificación para un edificio sin aire acondicionado (nAC). La cuantificación de la diferencia también se realiza para el mismo edificio con AC. Las simulaciones se realizaron utilizando EnergyPlus y considerando cuatro casos de estudio según los sistemas constructivos de muros y techos. El edificio es una casa ubicada en Monterrey, ciudad mexicana con un verano caluroso y un invierno suave. Para la casa nAC las diferencias en los promedios mensuales de las temperaturas máximas diarias y mínimas diarias entre las simulaciones M y las NM son de hasta 8.3°C y 6.4°C, respectivamente, y las diferencias para los grados hora de disconfort frío y calor son de hasta 124 %. Para la casa con AC, las diferencias entre las simulaciones M y NM en las cargas térmicas de refrigeración y calefacción son de hasta 30 %. La diferencia en la demanda de potencia máxima de aire acondicionado es de hasta 38 %, y la diferencia en el tiempo en que ocurre este pico es de hasta 4 horas. Estos resultados muestran que las diferencias entre las simulaciones son mayores para la casa nAC que para la casa AC.

Abstract: Building thermal simulation (BTS) programs are being increasingly used to evaluate the occupants’ thermal comfort and the building’s energy consumption. Although some authors have pointed out that not taking into account the thermal mass of the building’s components results in erroneous performance predictions, some BTS program users, standards and building rating systems still do not consider the thermal mass. The quantification of the difference in the simulations’ predictions of the performance of a building when its thermal mass is either considered (M) or ignored (NM) have been reported in the literature for air-conditioned buildings (AC). In this work, and for the first time, the quantification is made for a non-air-conditioned (nAC) building. The quantification of the difference between M and NM simulations’ results is also made for the same building but with AC. Simulations were carried out using EnergyPlus and considering four study cases according to the constructive systems of walls and roofs. The building is a house located in Monterrey, a Mexican city with a hot summer and a mild winter. For the nAC house the differences in monthly averages for the daily maximum and for the daily minimum temperatures between M and NM simulations are up to 8.3oC and 6.4oC respectively, and differences for the cold and hot discomfort degree hours are up to 124 %. For the AC house the differences between M and NM simulations on the cooling and heating thermal loads are up to 30 %. The difference in the air conditioning peak power demand is up to 38 %, and the difference in the time this peak occurs is up to 4 hours. These results show that differences between simulations are larger for the nAC house than they are for the AC house.

Abstract The family is one of the most basic institutions of society, which has evolved over the years, leaving behind the traditional concepts that inspired it. This has allowed, for example, the recognition of the assembled lineages in our legal system. The Constitutional Court of Peru has affirmed to the members of these lineages a series of rights and duties in life, under the protection of the right to equality and non-discrimination. However, it omits to pronounce on the right to inheritance. We propose to analyze whether its reasoning so far is suitable, from a constitutional and international perspective, to extend its protection to the patrimonial rights from the inter vivos plane to the mortis causa and thus fill the existing normative void with regard to the institution that is the subject of this research; specifically, in the hereditary sphere in the parent-stepchild relationship.

Resumen La familia es una de las instituciones más básicas de la sociedad, que ha evolucionado a lo largo de los años, dejando atrás los conceptos tradicionales que la inspiraban. Ello ha permitido, por ejemplo, el reconocimiento de las estirpes ensambladas en nuestro ordenamiento jurídico. El Tribunal Constitucional del Perú les ha afirmado a los integrantes de estos linajes una serie de derechos y deberes en vida, al amparo del derecho a igualdad y no discriminación. Sin embargo, omite pronunciarse en lo que se refiere al derecho a la herencia. Nos proponemos analizar si sus razonamientos hasta el momento son idóneos, desde una perspectiva constitucional e internacional, para extender su protección a los derechos patrimoniales del plano inter vivos al mortis causa y así suplir el vacío normativo existente en lo que se refiere a la institución materia de esta investigación; concretamente, en el ámbito hereditario en la relación padre-hijo afín.

RESUMEN Antecedentes: El objetivo de este estudio fue de adaptar y validar una versión para personal educador de los instrumentos PLANEA de evaluación de habilidades para la vida independiente. Dichos instrumentos se emplearon para explorar la convergencia entre el nivel de habilidades para la vida independiente percibido por jóvenes en acogimiento residencial y sus educadores. Método: La muestra se compuso de 422 jóvenes residentes en recursos de acogimiento residencial o de apoyo para extutelados, quienes fueron evaluados por personal educador (n = 219) utilizando los instrumentos PLANEA. Se realizaron análisis estadísticos para estudiar la dimensionalidad y propiedades psicométricas de los instrumentos y se emplearon pruebas t de Student, correlaciones de Pearson y z de Fisher para estudiar el nivel de convergencia entre informantes. Resultados: Los resultados confirman la estructura interna esperada para los instrumentos (tres factores de primer orden y un factor de segundo orden para PLANEA-S, modelo unidimensional para PLANEA-9-S y modelo bifactorial correlacionado para PLANEA-T-S). Los instrumentos mostraron niveles excelentes de fiabilidad (ω = .80-.97) y capacidad discriminativa. El personal informó de menor nivel de habilidades para la vida independiente que el grupo de jóvenes, pero no de autonomía en la vida diaria, lo cual estuvo mediado por el rol del informante adulto con respecto al joven. Conclusiones: Se concluye que la versión para educadores de los instrumentos PLANEA de evaluación de habilidades para la vida independiente amplía el campo de evaluación de este constructo en jóvenes en acogimiento desde una perspectiva multiinformante, lo que es clave para que los servicios de protección infantil puedan identificar y atender las necesidades individuales de estos jóvenes, seleccionando los apoyos necesarios en cada caso para la promoción de una transición exitosa desde el sistema de protección a la vida adulta.

ABSTRACT Background: This study aimed to adapt and validate a staff version of the PLANEA Independent Life Skills Assessment tools, which were then used to explore the convergence between self-reported and staff views of independent living skills of young people in residential child care in Spain. Method: A sample of 422 care-experienced young people was evaluated by their residential or care workers (n = 219) using the staff version of PLANEA instruments. Psychometric analyses were carried out to study dimensionality and measuring properties of the instruments, while t-tests, Pearson correlations and Fisher’s z were used to study convergence between informants. Results: The results show that the internal structure of the instruments was confirmed for the staff versions (three first-order factors and one second-order factor model for PLANEA-S, unidimensional model for PLANEA-9-S, and two-factor correlated model for PLANEA-T-S). The instruments showed excellent reliability (ω = .80-.97) and discriminative capacity. Staff showed less optimistic views than young people about their independent living skills but not their autonomy to perform everyday life tasks. This was mediated by the role of the adult respondent towards the young person evaluated. Conclusions: As conclusions we can say that the validated staff version of the PLANEA Independent Life Skills Assessment tools expands the scope for assessing this construct in young people in care from a multi-informant perspective. This is key for child protection services to address young people’s individual needs and inform decision-making regarding the provision of support services that will promote a successful transition from care to adulthood for them.

Resumen Introducción: el laboratorio de citogenética del Instituto de Investigaciones en Salud (INISA) de la Universidad de Costa Rica estableció un Servicio de Dosimetría Biológica en enero del 2020 utilizando biomarcadores citogenéticos de exposición a radiaciones ionizantes. Es el primero de su tipo en la región centroamericana. Objetivo: establecer un servicio de dosimetría biológica para Costa Rica, elaborando una curva de calibración dosis-efecto para rayos gamma. Metodología: para la realización de la curva de calibración se irradiaron muestras de sangre periférica in vitro con rayos gamma de dos voluntarios, uno femenino y otro masculino, en 11 puntos de dosis en el rango de 0 a 5 Gy. Se cultivó la sangre acorde a los protocolos internacionales durante 48 horas y se registraron las aberraciones inducidas. Los programas Dose Estimate V5.2 y R versión 4.03 se utilizaron para el cálculo de los coeficientes de la curva de calibración que correlaciona la frecuencia de cromosomas dicéntricos con la dosis. Resultados: los coeficientes de la curva son α: 0.02737±0.00658, ß: 0,05938±0,00450 y C: 0.00129±0.00084. Estos coeficientes tienen valores similares a los reportados internacionalmente. La curva se validó calculando dos dosis incógnitas, en la primera incógnita la dosis suministrada fue de 1,5 Gy y la dosis estimada fue 1,47 Gy y en la segunda la dosis suministrada fue de 4 Gy y la dosis estimada fue 3,616 Gy, para ambos casos no existen diferencias estadísticamente significativas entre las dosis suministradas y las estimadas. Conclusiones: actualmente El Servicio de Dosimetría Biológica del INISA puede estimar dosis absorbida en personas que se sospecha de una sobre exposición a rayos gamma en personal ocupacionalmente expuesto o personas involucradas en un accidente radiológico.

Abstract Introduction. The cytogenetics laboratory of the Health Research Institute (INISA) of the University of Costa Rica established a Biological Dosimetry Service in January 2020 using cytogenetic biomarkers of exposure to ionizing radiation. It is the first of its kind in the Central American region. Objective: establish a biological dosimetry service for Costa Rica, developing a dose-effect calibration curve for gamma rays. Methodology: to carry out the calibration curve, peripheral blood samples from two volunteers, one female and the other male, were irradiated in vitro with gamma rays, at 11 dose points in the range of 0 to 5 Gy. Blood was cultured according to international protocols for 48 hours and induced aberrations were recorded. The Dose Estimate V5.2 and R version 4.03 programs were used to calculate the coefficients of the calibration curve that correlates the frequency of dicentric chromosomes with the dose. Results: the coefficients of the curve are α: 0.02737 ± 0.00658, ß: 0.05938 ± 0.00450 and C: 0.00129 ± 0.00084. These coefficients have values similar to those reported internationally. The curve was validated by calculating two unknown doses, in the first unknown case the delivered dose was 1.5 Gy and the estimated dose was 1.47 Gy and in the second case the delivered dose was 4 Gy and the estimated dose was 3.616 Gy. for both cases there are no statistically significant differences between the delivered and estimated doses. Conclusions: the Biological Dosimetry Service of the INISA can estimate absorbed dose in persons suspected of overexposure to gamma rays in occupationally exposed personnel or persons involved in a radiological accident.Health is loaded with symbolisms and practical manifestations that differ according to social groups and sociocultural contexts. In order to make everyday life and needs visible, the Theoretical Paradigm of Social Representations provides the theoretical-methodological bases necessary to understand the common sense knowledge associated with health among the Nicaraguan migrant population in Costa Rica. Methodology: Qualitative study with ethnographic approach that aimed to identify the social representation of health, through the process of objectification, present among Nicaraguan migrants living in Costa Rica. Data collected through semi-structured interviews, participant observation, and field diaries. Processing according to Content Analysis. Results: The social representation of health found behaves analogously to a formula; where, the search for peaceful environments is added to the achievement of financial stability to result in two interdependent representations: 1) Health as physical-mental strength; and 2) Health as a future and abstract sensation of well-being, happiness and transcendence. The socio-political antecedents in Nicaragua, the migratory process, and the adaptation to Costa Rica play a preponderant role in shaping the representation on health. Conclusion: Social representations about health have direct practical implications on the ways of life and needs of migrant groups. Understanding their common sense knowledge allows to move towards more contextualized public policies. More integration of the thoughts, opinions and feelings of migrants in decision-making platforms is recommended.

Abstract The litterfall that accumulates in the forest soil and its further decomposition play an important roll in the maintenance of productivity in different terrestrial ecosystems since its constitute the main flow of nutrients to the soil. The objective of this study was to evaluate the production of litterfall, its nutrient return thru litterfall deposition and macronutrient use efficiency. The study was conducted in Linares, Crucitas and Los Ramones, state of Nuevo León, México. Average litterfall deposition was 5 800, 5 270 and 6 596 kg ha−1 year−1 for Linares, Crucitas and Los Ramones, respectively. Total nutrient return thru litterfall followed the sequence: Linares > Crucitas > Los Ramones, with value of 135, 122 and 101 kg ha−1 year−1, respectively. Even though the return of P thru litterfall was the lowest, P nutrient use efficiency was higher with respect to Ca, Mg and K. Greatest nutrient use efficiency in terms of Ca and Mg was observed in Los Ramones, K in Crucitas and P in Linares. The results showed that there exist spatial and temporal variation in the production of litterfall, nutrient return and nutrient use efficiency between studied sites. Thus, litterfall deposition, nutrient return and nutrient use efficiency between sites depend on stand composition and richness, edaphic properties, litterfall quality, and plant phenology.

Resumen La hojarasca que se acumula sobre el piso forestal y su posterior descomposición juegan un papel importante en el mantenimiento de la productividad de los diferentes ecosistemas terrestres al constituir el principal flujo de nutrientes al suelo. El objetivo del estudio fue evaluar la producción de hojarasca y retorno de nutrientes a través de la caída de la hojarasca y la eficiencia en el uso de macro-nutrientes. El estudio se realizó en los sitios de Linares, Crucitas y Los Ramones, en el Estado de Nuevo León, México. El promedio de caída de hojarasca fue de 5 800, 5 270 a 6 596 kg ha−1 año−1 para Linares, Crucitas y Los Ramones, respectivamente. El retorno total de nutrientes siguió la secuencia: Linares > Crucitas > Los Ramones con valores de 135, 122 y 101 kg ha−1 año−1, respectivamente. A pesar de que el retorno de P en la hojarasca fue menor, la eficiencia del uso de este nutriente fue mayor que la presentada por el Ca, Mg ó K. La mayor eficiencia de uso de nutrientes en términos de Ca y Mg se observó en Los Ramones, el K en Crucitas y el P en linares. Existe variación espacial y temporal en la producción de hojarasca, retorno de nutrientes y la eficiencia en su uso entre los sitios evaluados. Por tanto, la caída de hojarasca, retorno de nutrientes y uso eficiente en estos sitios dependen de la riqueza de especies, diferencias edáficas, calidad de la hojarasca y fenología de las diferentes especies.
