RESUMO
The present study aimed to investigate the moderating effect of perceived punishment on the relationship between the Dark Triad personality traits and corruption in Brazil (N = 118) and the United Kingdom (N = 130). Participants answered the Dark Triad Dirty Dozen Scale, as well as measures of corruption and perceived punishment. It was found that punishment predicts corruption in both countries. Regarding the Dark Triad traits, a relationship between Machiavellianism and corruption was identified in Brazil and the United Kingdom, although an interaction with punishment was identified only in Brazil. Moreover, psychopathy had no relationship with corruption or punishment in either country. A direct relationship was found only in Brazil on narcissism, although the interaction term was significant in both countries. In general, it was identified that perceived punishment and the dark triad traits contribute to the understanding of corruption, despite some differences in the results between Brazil and the United Kingdom.
O presente estudo tem como objetivo investigar o papel moderador da percepção de punição na relação entre Tríade Sombria da personalidade e corrupção no Brasil (N = 118) e no Reino Unido (N = 130). Participantes responderam à Escala Dark Triad Dirty Dozen, bem como a medidas de corrupção e percepção de punição. Foi encontrado que a punição prediz a corrupção em ambos os países. Em relação à Tríade Sombria, o relacionamento entre maquiavelismo e corrupção foi identificado no Brasil e no Reino Unido, embora a interação com a punição tenha sido identificada apenas no Brasil. Adicionalmente, a psicopatia não teve relação com a corrupção ou com a punição em nenhum dos países. Um efeito direto do narcisismo foi encontrado apenas no Brasil, apesar do termo de interação ter sido significativo em ambos os países. De forma geral, foi identificado que a percepção de punição e a tríade sombria contribuíram com a compreensão da corrupção, apesar de algumas diferenças nos resultados entre Brasil e Reino Unido.

RESUMO
Introduction: Gram-positive staphylococci are responsible for over 90% of cases of postoperative infectious endophthalmitis, with Staphylococcus epidermidis accounting for approximately 70% of isolated microorganisms. Objective: To evaluate the relationship between S. epidermidis virulence and severity of endophthalmitis in an animal model. Methodology: New Zealand albino rabbits were divided into two groups and administered 100 colony-forming units of S. epidermidis strains. In the virulent group, four rabbits received a multi-antibiotic resistant, mecA, ica, and atlE gene carrying S. epidermidis strain, from a patient´s conjuntival microbiota and three a biofilm-forming S. epidermidis ATCC 35984. In the non-virulent group, five rabbits were inoculated with a strain sensitive to all tested antibiotics and lacking mecA, ica, and atlE genes, also from a patient and three rabbits received the non-producer biofilm S. epidermidis ATCC 29122. Clinical and ultrasound examinations were conducted every three hours until endophthalmitis symptoms appeared, followed by daily clinical assessments. Histological evaluations were performed 15 days post-inoculation. Results: The less virulent group displayed milder inflammation and reduced intraocular damage in comparison to the more virulent group based on clinical and ultrasound observations. Nevertheless, histopathological analysis revealed similar inflammation in all groups, 15 days post-inoculation. Discussion: Less virulent S. epidermidis strains induced less severe inflammation as observed through clinical and ultrasound assessments. However, long-term histopathological assessments showed effects comparable to those seen with the more virulent strain.
Introducción: Gram-positive staphylococci are responsible for over 90% of cases of postoperative infectious endophthalmitis, with Staphylococcus epidermidis accounting for approximately 70% of isolated microorganisms. Objetivo: Evualuar la relación entre la virulencia de S. epidermidis y la gravedad de la endoftalmitis en un modelo animal. Metodología: Se dividieron conejos albinos de Nueva Zelanda en dos grupos y se les administraron 100 unidades formadoras de colonias de cepas de S. epidermidis. En el grupo virulento, cuatro conejos recibieron una cepa multirresistente de S. epidermidis portadora de gen mecA, ica y atlE, de la microbiota conjuntival de un paciente y tres conejos la cepa S. epidermidis ATCC 35984 formadora de biopelículas. En el grupo no-virulento, se inocularon cinco conejos con una cepa sensible a todos los antibióticos probados y que carecía de los genes mecA, ica y atlE, también de un paciente y tres conejos recibieron la cepa S. epidermidis ATCC 29122 no productora de biopelícula. Se realizaron exámenes clínicos y ecográficos cada tres horas hasta la aparición de síntomas de endoftalmitis, seguido de evaluaciones clínicas diarias. Las evaluaciones histológicas se realizaron 15 días después de la inoculación. Resultados: El grupo menos virulento mostró una inflamación más leve y un daño intraocular reducido en comparación con el grupo más virulento según observaciones clínicas y ecográficas. Sin embargo, el análisis histopatológico reveló una inflamación similar en todos los grupos, 15 días después de la inoculación. Discusión: Las cepas de S. epidermidis menos virulentas indujeron una inflamación menos grave, como se observó mediante evaluaciones clínicas y ecográficas. Sin embargo, las evaluaciones histopatológicas a largo plazo mostraron efectos comparables a los observados con la cepa más virulenta.

RESUMO
Traumatic brain injury (TBI) remains a significant public health concern worldwide, necessitating effective research models to elucidate its pathophysiology and develop therapeutic interventions. Animal models play a crucial role in TBI research, offering valuable insights into injury mechanisms and potential treatments. However, selecting the appropriate model can be challenging due to diverse array of available options and their respective advantages and limitations. In this comprehensive review, we examine four commonly used animal models of TBI: the weight drop, fluid percussion, cortical impact, and blast injury models. Each model is characterized by distinct injury mechanisms, allowing researchers simulate various aspects of TBI pathology. We discuss the unique advantages and disadvantages of each model, providing insights into their applications and considerations for model selection based on research objectives and outcome measures. Furthermore, we highlight emerging directions in TBI modelling, emphasizing the importance of refining and innovating models to replicate the complexity of human TBI. By critically evaluating and understanding the subtlety of different TBI models, researchers can make informed decisions to enhance the translational potential of preclinical TBI research and ultimately improve clinical outcomes for TBI patients.

RESUMO
ABSTRACT Fruit production forecasts are a tool to plan the harvest and improve market strategies. To carry it out, it is essential to have information about the behavior of fruit development over time. The objective of this work was to find the mathematical-statistical model that best describes the growth pattern of tangor murcott fruit (Citrus reticulata x C. sinensis 'Murcott') and analyze how it is affected by environmental conditions. For this, in nine orchards, located in four locations in the province of Corrientes, Argentina, the equatorial diameter of 2,053 fruit from 82 days after full flowering to harvest were periodically registered during five seasons. The nonlinear models were compared: Logistic, Gompertz, Brody, Von Bertalanffy, Weibull, Morgan Mercer Flodin (MMF), Richards, and their respective re-parameterizations. The magnitudes of nonlinearity measures, coefficient of determination and estimates of residual deviation were considered as the main goodness-of-fit criteria. The selected model-parameterization combination was the fifth parameterization of the Logistic model with random effects on its three parameters. An Analysis of Variance model on the estimates of these parameters for each fruit showed that orchard and season factors were an important source of variability, mainly in those related to the initial size of the fruit and their growth rate. These results will allow the construction of growth tables, which in addition to making yield predictions, can be used to estimate fruit size distribution at harvest and improve the cultural practice of manual fruit thinning.
RESUMEN Los pronósticos de producción de fruta son una herramienta para planificar la cosecha y mejorar estrategias de mercado. Para su realización es imprescindible contar con información acerca del desarrollo de los frutos a lo largo del tiempo. El objetivo del presente trabajo fue encontrar el modelo matemático-estadístico que mejor describa el patrón de crecimiento de frutos tangor murcott (Citrus reticulata x C. sinensis 'Murcott') y analizar cómo es afectado por condiciones medioambientales. En nueve huertos, ubicados en cuatro localidades en la provincia de Corrientes, Argentina, se registró durante cinco temporadas el diámetro ecuatorial de 2053 frutos desde los 82 días después de plena floración hasta el momento de cosecha. Se compararon los modelos no lineales: Logístico, Gompertz, Brody, Von Bertalanffy, Weibull, Morgan Mercer Flodin (MMF), Richards, y sus respectivas re-parameterizaciones. Como principales criterios de bondad de ajuste se consideraron las magnitudes de medidas de no linealidad, coeficiente de determinación y estimaciones del desvío residual. La combinación modelo-parametrización seleccionada fue la quinta parametrización del modelo Logístico con efectos aleatorios en sus tres parámetros. Un modelo de análisis de la variancia sobre las estimaciones de estos parámetros para cada fruto mostró que los factores huerto y temporada eran una importante fuente de variabilidad, principalmente en los relacionados con el tamaño inicial de los frutos y su tasa de crecimiento. Estos resultados permitirán construir tablas de crecimiento, que además de realizar predicciones de rendimientos, podrán ser utilizadas para estimar distribución de tamaños de fruto a cosecha y mejorar la práctica cultural de raleo.
RESUMO
RESUMEN La fotocatálisis homogénea foto-Fenton es uno de los procesos de oxidación avanzada más utilizados en el tratamiento de aguas residuales con contenido de pesticidas, donde la optimización de la dosis de catalizador y el agente oxidante, teniendo como respuesta la mineralización en términos de carbón orgánico total (COT) o la eliminación del contaminante específico, son el objetivo de cualquier diseño experimental. El desarrollo experimental en los procesos de tratamiento requiere la ejecución de una cantidad significativa de condiciones experimentales que necesitan el uso de reactivos, energía y tiempo de ejecución, por lo tanto, el modelamiento de este tipo de fenómenos surge como una alternativa a esta limitante en los tratamientos de aguas residuales. En esta investigación, se evaluó la influencia de los factores FeSO4 y H2O2, cada uno en tres niveles, en la mineralización de una solución sintética del insecticida Carbendazim (50 mg.L-1), en términos de COT, mediante un modelo de regresión lineal múltiple y optimizado por una superficie de respuesta. Los principales resultados establecieron que el mejor ajuste del modelo se da teniendo en cuenta la interacción entre el FeSO4 y el H2O2 (X1*X2) y los términos cuadráticos de cada una de ellas con p-values <0,05 y que la validación del modelo, mediante la técnica Leave-One-Out Cross Validation (LOOCV), así como la exactitud y la precisión, mediante el análisis de residuos y el supuesto de mínimos cuadrados ordinarios, establecen que las conclusiones que se deriven de él son válidas.
ABSTRACT Homogeneous photo-Fenton photocatalysis is one of the most widely used advanced oxidation processes in treating wastewater containing pesticides, where optimizing the catalyst dosage and oxidizing agent, with the response being mineralization in terms of total organic carbon (TOC) or removal of the specific contaminant, is the goal of any experimental design. Experimental development in treatment processes necessitates executing a significant number of experimental conditions that require the use of reagents, energy, and execution time. Therefore, modeling such phenomena emerges as an alternative to these limitations in wastewater treatment. In this research, the influence of factors FeSO4 and H2O2, each at three levels, on the mineralization of a synthetic solution of the insecticide Carbendazim (50 mg.L-1) in terms of TOC was evaluated using a multiple linear regression model optimized by response surface methodology. The main results established that the best model fit considers the interaction between FeSO4 and H2O2 (X 1 *X 2 ) and the quadratic terms of each with p-values<0.05. The validation of the model using the Leave-One-Out Cross Validation (LOOCV) technique, as well as accuracy and precision through residual analysis and ordinary least squares assumptions, confirms the validity of the conclusions derived from it.
RESUMO
Abstract Objective: Periventricular-intraventricular hemorrhage is the most common type of intracranial bleeding in newborns, especially in the first 3 days after birth. Severe periventricular-intraventricular hemorrhage is considered a progression from mild periventricular-intraventricular hemorrhage and is often closely associated with severe neurological sequelae. However, no specific indicators are available to predict the progression from mild to severe periventricular-intraventricular in early admission. This study aims to establish an early diagnostic prediction model for severe PIVH. Method: This study was a retrospective cohort study with data collected from the MIMIC-III (v1.4) database. Laboratory and clinical data collected within the first 24 h of NICU admission have been used as variables for both univariate and multivariate logistic regression analyses to construct a nomogram-based early prediction model for severe periventricular-intraventricular hemorrhage and subsequently validated. Results: A predictive model was established and represented by a nomogram, it comprised three variables: output, lowest platelet count and use of vasoactive drugs within 24 h of NICU admission. The model's predictive performance showed by the calculated area under the curve was 0.792, indicating good discriminatory power. The calibration plot demonstrated good calibration between observed and predicted outcomes, and the Hosmer-Lemeshow test showed high consistency (p = 0.990). Internal validation showed the calculated area under a curve of 0.788. Conclusions: This severe PIVH predictive model, established by three easily obtainable indicators within the NICU, demonstrated good predictive ability. It offered a more user-friendly and convenient option for neonatologists.
RESUMO
Abstract Objective: Reliably prediction models for coronary artery abnormalities (CAA) in children aged > 5 years with Kawasaki disease (KD) are still lacking. This study aimed to develop a nomogram model for predicting CAA at 4 to 8 weeks of illness in children with KD older than 5 years. Methods: A total of 644 eligible children were randomly assigned to a training cohort (n = 450) and a validation cohort (n = 194). The least absolute shrinkage and selection operator (LASSO) analysis was used for optimal predictors selection, and multivariate logistic regression was used to develop a nomogram model based on the selected predictors. Area under the receiver operating characteristic curve (AUC), calibration curves, Hosmer-Lemeshow test, Brier score, and decision curve analysis (DCA) were used to assess model performance. Results: Neutrophil to lymphocyte ratio, intravenous immunoglobulin resistance, and maximum baseline z-score ≥ 2.5 were identified by LASSO as significant predictors. The model incorporating these variables showed good discrimination and calibration capacities in both training and validation cohorts. The AUC of the training cohort and validation cohort were 0.854 and 0.850, respectively. The DCA confirmed the clinical usefulness of the nomogram model. Conclusions: A novel nomogram model was established to accurately assess the risk of CAA at 4-8 weeks of onset among KD children older than 5 years, which may aid clinical decisionmaking.
RESUMO
Introducción: En modelos de producción vocal que emplean estructuras de resorte-masa-amortiguador, la precisión en la determinación de coeficientes de amortiguamiento que se asemejen a las características fisiológicas de las cuerdas vocales es crucial, teniendo en cuenta posibles variaciones en la representación de la viscoelasticidad. Objetivo: Este estudio tiene como objetivo realizar un ajuste paramétrico de un modelo de producción vocal basado en un sistema de resorte-masa-amortiguador que incorpora interacción con la presión subglótica, con el fin de modelar de manera precisa las fuerzas de colisión ejercidas por las cuerdas vocales durante la fonación. Método: Se utilizó un algoritmo de búsqueda metaheurística para la síntesis paramétrica. El algoritmo se aplicó a los coeficientes de elasticidad c1 y c2, así como a los coeficientes de amortiguamiento ε1 y ε2, que se correlacionan directamente con las matrices de masa del modelo. Esto facilita el ajuste de la composición de las cuerdas para lograr un comportamiento fisiológico deseado. Resultados: El comportamiento del sistema vocal para cada ciclo de simulación se comparó con un estándar predefinido en condiciones normales. El algoritmo determinó el punto final de la simulación evaluando las discrepancias entre características clave de las señales obtenidas y las deseadas. Conclusión: El ajuste paramétrico permitió la aproximación del comportamiento fisiológico de la producción vocal, proporcionando estimaciones de las fuerzas de impacto experimentadas por las cuerdas vocales durante la fonación.
Introduction: In vocal production models employing spring-mass-damper frameworks, precision in determining damping coefficients that align with physiological vocal fold characteristics is crucial, accounting for potential variations in the representation of viscosity-elasticity properties. Objective: This study aims to conduct a parametric fitting of a vocal production model based on a mass-spring-damper system incorporating subglottic pressure interaction, with the purpose of accurately modeling the collision forces exerted by vocal folds during phonation. Method: A metaheuristic search algorithm was employed for parametric synthesis. The algorithm was applied to elasticity coefficients c1 and c2, as well as damping coefficients ε1 and ε2, which directly correlate with the mass matrices of the model. This facilitates the adjustment of fold composition to achieve desired physiological behavior. Results: The vocal system's behavior for each simulation cycle was compared to a predefined standard under normal conditions. The algorithm determined the simulation endpoint by evaluating discrepancies between key features of the obtained signals and the desired ones. Conclusion: Parametric fitting enabled the approximation of physiological vocal production behavior, providing estimates of the impact forces experienced by vocal folds during phonation.
RESUMO
Background: Breast cancer, which is the most prevalent and common cause of death in women in the world and Turkey, is an important public health problem. The aim of this study is to evaluate the level of breast cancer risk according to the Gail model in a group of Turkish women and to determine the factors affecting the rates of early diagnosis and screening. Methods: A cross-sectional study in Turkey. A total of 1332 women who were aged between 40 and 69 participated. The study data were collected by using a questionnaire consisting of questions about sociodemographic characteristics, lifestyle, early diagnosis and screening behaviors, and Gail model questions for determining the breast cancer risk level. Results: The risk was higher in women who had their first childbirth at the age of ?30 years and had a first-degree relative with a history of breast cancer (p<0.05). There was a significant relationship between the breast self-examination behavior of the women and their age, education level, and family history of cancer, between their clinical breast examination behavior and age, education level, employment status, and chronic disease history, and between the behavior of getting a mammogram and age, education level, and chronic disease history (p<0.05). Conclusions: Accurate assessment of breast cancer risk and participation of women in screening programs reduce morbidity and mortality rates.

RESUMO
ABSTRACT Background: Since to the prognosis of lung squamous cell carcinoma is generally poor, there is an urgent need to innovate new prognostic biomarkers and therapeutic targets to improve patient outcomes. Objectives: Our goal was to develop a novel multi-gene prognostic model linked to neutrophils for predicting lung squamous cell carcinoma prognosis. Methods: We utilized messenger RNA expression profiles and relevant clinical data of lung squamous cell carcinoma patients from the Cancer Genome Atlas database. Through K-means clustering, least absolute shrinkage and selection operator regression, and univariate/multivariate Cox regression analyses, we identified 12 neutrophil-related genes strongly related to patient survival and constructed a prognostic model. We verified the stability of the model in the Cancer Genome Atlas database and gene expression omnibus validation set, demonstrating the robust predictive performance of the model. Results: Immunoinfiltration analysis revealed remarkably elevated levels of infiltration for natural killer cells resting and monocytes in the high-risk group compared to the low-risk group, while macrophages had considerably lower infiltration in the high risk group. Most immune checkpoint genes, including programmed cell death protein 1 and cytotoxic T-lymphocyte-associated antigen 4, exhibited high expression levels in the high risk group. Tumor immune dysfunction and exclusion scores and immunophenoscore results suggested a potential inclination toward immunotherapy in the "RIC" version V2 revised high risk group. Moreover, prediction results from the CellMiner database revealed great correlations between drug sensitivity (e.g., Vinorelbine and PKI-587) and prognostic genes. Conclusion: Overall, our study established a reliable prognostic risk model that possessed significant value in predicting the overall survival of lung squamous cell carcinoma patients and may guide personalized treatment strategies.

RESUMO
Resumen En este trabajo se estudia un modelo de ecuaciones diferenciales ordinarias no lineales que describe la relación entre la masa de células β y la secreción de epinefrina. Se analiza el impacto del estrés asociado como causante de incremento de los niveles de glucosa en el organismo. El análisis matemático se fundamenta en la aplicación de la teoría de control no lineal para definir la capacidad de carga máxima para cada variable de estado, estableciendo un dominio invariante positivo acotado a través del método de Localización de Conjuntos Compactos Invariantes (LCCI). El objetivo es determinar los efectos asociados a la secreción de epinefrina en el aumento de los niveles de glucosa en sangre; por lo tanto, los resultados de este análisis ayudan a definir las condiciones necesarias y suficientes en las que la epinefrina eleva los niveles de insulina y glucosa en presencia de células β. El interés por estudiar este tipo de enfermedades se enfoca en la búsqueda de un tratamiento o un análisis que garantice un control completo de los niveles de glucosa. El desarrollo y análisis matemático de este trabajo fortalece la investigación vigente de diabetes mellitus insulinodependiente entorno a factores críticos de epinefrina que implican un incremento de glucosa en el organismo.
Abstract In this work, a nonlinear model is studied based on ordinary differential equations that describe the relationship between the mass of β cells and the secretion of epinephrine. It analyzes the impact of stress associated with the cause of increased blood pressure and glucose levels in the body. The mathematical analysis is based on the appliance of the nonlinear control theory to define the maximum load capacity for each state variable, establishing a bounded positive invariant domain through the Localization of Compact Invariants Sets (LCIS) method. The objective is to determine the effects of epinephrine secretion on the increase of blood glucose levels; therefore, this analysis's results define the necessary and sufficient conditions in which epinephrine raises insulin and glucose levels in the presence of β cells. The interest in studying this type of disease focuses on searching for a treatment or an analysis that guarantees complete control of glucose levels. This work's development and mathematical analysis strengthen current research on insulin-dependent diabetes mellitus around critical epinephrine factors that imply an increase in glucose in the body.
RESUMO
El presente estudio busca definir los parámetros de la cámara fotográfica y encuadre de la imagen para generar fotografías estandarizadas a modelos dentales de yeso que permitan realizar mediciones intermaxilares a través de fotogrametría, y que estas distancias sean tan confiables y válidas como el registro físico. Se realizó medición directa de los modelos con compás de Korkhaus y medición indirecta a través de fotogrametría digital, evaluando si existía diferencia estadística entre ambas mediciones. Como resultado, no se observaron diferencias significativas entre el protocolo digital con un objetivo 100 mm y magnificación 1:4 en comparación con las mediciones directas, por lo que se concluye que con los parámetros seleccionados se logra una adecuada precisión en la fotogrametría respecto a la medición directa.
This study aims to compare the different parameters of the photographic camera with the digital image framing to standardize dental model photography, in order to take intermaxillary measurements through photogrammetry, and so that these distances are as reliable and valid as the physical record. Direct measurement of the models was made with a Korkhaus compass, and indirect measurement through digital photogrammetry, evaluating whether there was a statistical difference between both measurements. As a result, no significant differences were observed between the digital protocol with a 100 mm objective and 1:4 magnification and the direct measurements. It is concluded that with the selected parameters, adequate precision is achieved in photogrammetry, when compared to the direct measurement.

RESUMO
Introducción: La vivencia de experiencias adversas en la infancia (EAI) se asocia a mayor riesgo de presentar conductas de riesgo y enfermedades crónicas a largo plazo. A nivel mundial, se han comenzado a pesquisar y abordar en las atenciones de salud. Sin embargo, en Chile aún no existe una sugerencia a nivel nacional para incorporarlo. El fin de este artículo es proveer de información y recomendaciones a la práctica clínica. Métodos: Se realizó una revisión exploratoria en PubMed, LILACS y PsycInfo usando el marco metodológico del Joanna Briggs Institute para identificar la literatura disponible sobre implementación de intervenciones en detección y abordaje de EAI dentro de un sistema de salud, con foco en atención infantil ambulatoria. Resultados: Se encontraron 34 estudios atingentes al tema, los que muestran que implementar mecanismos de detección y abordaje de EAI es factible y aceptable, tanto para el personal de salud como para los usuarios, pero debe ser realizado dentro de un modelo de cuidado que incorpore a las familias y comunidad, además de trabajar con los equipos en capacitación, gestión del cambio, implementación y evaluación. Conclusiones: La Atención Primaria de Salud (APS) resulta ser un lugar privilegiado para su implementación dada la cercanía y relación de confianza que se establece con las familias. Este estudio muestra que es posible implementar un modelo de detección y abordaje de EAI en APS, lo que resulta crucial dentro de su rol preventivo-promocional si se quiere generar un impacto en la salud de niños, niñas y adolescentes ahora y en el futuro.
Introduction: Adverse childhood experiences (ACEs) are associated with an increased risk of developing risky health behaviors and chronic diseases in the long term. Screening for ACEs is beginning to be implemented worldwide in healthcare settings due to their known impact on present and future health. However, in Chile, there are no recommendations to incorporate ACEs screening into usual care. Methods: A scoping review was conducted using the Joanna Briggs Institute methodological framework to identify available literature on the implementation of interventions aimed at the detection and management of ACEs within a health system, specifically pediatric primary care. The search included PubMed, LILACS, and PsycInfo databases. Results: A total of 34 studies were included. They show that screening for ACEs is feasible and acceptable for both health care providers and users. However, it must be implemented as a part of a model of care that considers families and communities, besides working with health teams in training, change management, implementation, and evaluation. Conclusions: Primary Health Care (PHC) is a privileged setting for screening implementation because of the longitudinal and trust relationships established with families. This study concludes that it is possible to implement a model for detecting and managing ACEs in PHC, which will be crucial for its promotional and preventive role if there is a desire to generate an impact on infant and adolescent health now and in the future.
