Objetivos: Se pretende analizar las principales complicaciones a corto plazo (seis semanas) tras la Artroplastia total primaria de cadera. ;aterial y métodos: Se revisaron todos los pacientes a los que se realizó artroplastia total de cadera durante el año 2003. Las variables estudiadas fueron el índice de luxaciones, sangrado, infección, fracturas periprotésicas, complicaciones vásculo-nerviosas y mortalidad. Resultados: Obtuvimos una tasa del 4,4% de luxaciones; 1,7% de trombosis venosa profunda con un 0,87% de embolismo pulmonar, 1,7% de infecciones superficiales sin casos de infección profunda. El 14,9% de los casos necesitaron una transfusión postquirúrgica. Intraoperatoriamente observamos apertura del cálcar en el 3,5%, y fracturas periprotésicas postoperatorias en el 0,87%. No registramos complicaciones neurológicas ni mortalidad en estas primeras seis semanas del estudio. Conclusiones: La complicación más frecuente es la luxación, fundamentalmente en los casos secundarios a fractura. La trombosis venosa profunda, a èsar de la profilaxis, continúa siendo una complicación frecuente.Objectives: Our purpose was to analyze the main early complications (six weeks) after primary total hip arthroplasty. Materials and Methods: All patients who had undergone primary total hip replacement during 2003 were reviewed. The studied outcomes were the rates of dislocation, blood loss, infection, periprosthetic fractures, neural and vascular complications, and mortality. Results: Our rates were 4,4% for hip dislocation, 1,7% for deep vein thrombosis with 0,87% for pulmonary embolism, 1,7% for wound infection without cases of deep infection. 14,9% of the patients needed postoperative transfusion. We reported 3,5% fractures of the calcar during surgery and 0,87% of postoperative periprosthetic fractures. We didn ́t reported any neural complications or mortality within six weeks postoperatively. Conclusions: The most frequent complication is dislocation, mainly in cases whose underlying diagnose was hip fracture. Although prophylaxis is done, deep vein thrombosis goes on being a frequent complication

Antibacterial Properties of Nanoparticles in Dental Restorative Materials. A Systematic Review and Meta-Analysis

Background and Objectives: Nanotechnology has become a significant area of research focused mainly on increasing the antibacterial and mechanical properties of dental materials. The aim of the present systematic review and meta-analysis was to examine and quantitatively analyze the current evidence for the addition of different nanoparticles into dental restorative materials, to determine whether their incorporation increases the antibacterial/antimicrobial properties of the materials. Materials and Methods: A literature search was performed in the Pubmed, Scopus, and Embase databases, up to December 2018, following PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analysis) guidelines for systematic reviews and meta-analyses. Results: A total of 624 papers were identified in the initial search. After screening the texts and applying inclusion criteria, only 11 of these were selected for quantitative analysis. The incorporation of nanoparticles led to a significant increase (p-value < 0.01) in the antibacterial capacity of all the dental materials synthesized in comparison with control materials. Conclusions: The incorporation of nanoparticles into dental restorative materials was a favorable option; the antibacterial activity of nanoparticle-modified dental materials was significantly higher compared with the original unmodified materials, TiO2 nanoparticles providing the greatest benefits. However, the high heterogeneity among the articles reviewed points to the need for further research and the application of standardized research protocols

Estudio del comportamiento del sistema de protección de líneas de Extra Alta Tensión ante defectos resistivos a tierra

Este artículo presenta un estudio sobre la respuesta del sistema de protección de líneas de Extra Alta Tensión instalado en la Administración Nacional de Usinas y Trasmisiones Eléctricas (UTE) de Uruguay. El objetivo es poder determinar errores de los algoritmos de distancia de los equipos de protección, para considerarlo en la etapa de cálculo de ajustes. En general este error se considera como un porcentaje fijo de la longitud de la línea, sin tener en cuenta el algoritmo del relé ni las particularidades del sistema eléctrico. Conjuntamente se desarrollaron un conjunto de programas en entorno MATLAB® y su herramienta SIMULINK para estudiar defectos a tierra en una línea de Trasmisión y el algoritmo de los relés de protección de distancia. Cuando no se dispuso del algoritmo, se utilizaron los valores de tensión y corriente obtenidos en la simulación para ensayar un relé real, y así obtener la respuesta del mismo

Melatonin modulation of crosstalk among malignant epithelial, endothelial and adipose cells in breast cancer (Review)

Melatonin, the main secretory product of the pineal gland, is an oncostatic agent that reduces the growth and development of various types of tumors, particularly mammary tumors whose growth is dependent on estrogens. Previous in vivo and in vitro studies point to the hypothesis that melatonin interplays with estrogen signaling pathways at three different levels: i) an indirect mechanism, by interfering with the hypothalamic‑pituitary‑reproductive axis in such way that the level of plasma estrogens synthesized by the gonadal glands are downregulated; ii) a direct mechanism of the pineal gland at the cell cancer level, disrupting the activation of estradiol receptors, therefore behaving as a selective estrogen receptor modulator; and iii) by regulating the enzymes involved in the biosynthesis of estrogens in other tissues, thus behaving as a selective estrogen enzyme modulator. The intratumoral metabolism and synthesis of estrogens, as a result of the interactions of various enzymes, is more important than blood uptake to maintain mammary gland estrogen levels in menopausal females. Additionally, estrogens are considered to play an important role in the pathogenesis and development of hormone‑dependent breast carcinoma. Paracrine interactions among malignant epithelial cells and proximal adipose and endothelial cells, through cytokines and growth factors produced by breast tumor cells, modulate estrogen production at the mammary tumor level and, as a consequence, the genesis and development of mammary tumors. The aim of the present review is to summarize the recent findings describing the mechanisms by which melatonin is able to modulate the crosstalk among malignant epithelial, endothelial and adipose cells in breast cancer

Social support and mental health in maternity: Effects of the COVID-19 pandemic

[EN] Background: Motherhood involves a process of adaptation and the perception of social support influences mental health, breastfeeding or newborn care among others. The COVID-19 pandemic has generated a distancing from family, friends and health professionals. Methods: Quantitative, descriptive, cross-sectional study. The present study aims to describe and analyze the social support and mental health of mothers during this period. Methods: The sample were 179 women with children older than 6 months. The questionnaires used were the DUKE-UNC-11 and GHQ-12. Data analysis was carried out with Spearman's Rho and Mann Whitney U test. Results: 75.8% of the sample perceived normal social support during the pandemic. Within the dimensions of social support, women reported perceiving satisfactory confidential support, while affective support was perceived as low. Correlational analysis reported a significant relationship between mental health, confidential support and affective support. Group comparison noted greater confidential support in primiparous. Conclusions: The sample is sensitive to changes originated by COVID-19 constraints influencing perceived social support and mental health. Affective and confidential support as well as the involvement of health professionals and the environment are fundamental for mental health during the first year of maternity. Relevance to clinical practice: Mothers' mental health is sensitive and vulnerable to social changes, in this case, those that occurred as a consequence of the COVID-19 outbreak.S

Resolution of inflammation in obesity-induced liver disease

Low-grade inflammation in adipose tissue is recognized as a critical event in the development of obesity-related co-morbidities. This chronic inflammation is powerfully augmented through the infiltration of macrophages, which together with adipocytes, perpetuate a vicious cycle of inflammatory cell recruitment and secretion of free fatty acids and deleterious adipokines that predispose to greater incidence of metabolic complications. In the last decade, many factors have been identified to contribute to mounting unresolved inflammation in obese adipose tissue. Among them, pro-inflammatory lipid mediators (i.e., leukotrienes) derived from the omega-6 polyunsaturated arachidonic acid have been shown to play a prominent role. Of note, the same lipid mediators that initially trigger the inflammatory response also signal its termination by stimulating the formation of anti-inflammatory signals. Resolvins and protectins derived from the omega-3 polyunsaturated docosahexaenoic and eicosapentaenoic acids have emerged as a representative family of this novel class of autacoids with dual anti-inflammatory and pro-resolving properties that act as “stop-signals” of the inflammatory response. This review discusses the participation of these endogenous autacoids in the resolution of adipose tissue inflammation, with a special emphasis in the amelioration of obesity-related metabolic dysfunctions, namely insulin resistance and non-alcoholic fatty liver disease

The objective of the study was to determine if participating in traditional opposition games causes changes to the participants’ mood states. A total of 102 students participated. Each participant recorded the intensity of the mood state experienced at the beginning and at the end of the sessions, using the validated Profile of Mood States (POMS) instrument. The pedagogical experience was planned as 4 sessions with 6 and 5 opposition games each: (a) with competition in mixed groups, equally and unequally mixed; (b) without competition in mixed groups, equally and unequally mixed; (c) with competition in same-gender groups; and (d) without competition in same-gender groups. When comparing the different mood states according to session (with or without competition), the mood states of the depression, fatigue, and vigor dimensions were significantly different (p < 0.05), with higher scores in the sessions with competition for the mood states of vigor (Mcompetition = 7.27 and Mno_competition = 3.10) and fatigue (Mcompetition = 4.08 and Mno_competition = 1.80). Also, when comparing the mood states depending on session grouping and group type, the results showed differences in the scores obtained for the dimensions fatigue and anger, and general mood state (p < 0.05). These differences were found at the start of the session and at the end, with the dimension fatigue being the only one with differences in both situations when comparing the same-gender, equally-mixed, and unequally-mixed groups for the two types of traditional opposition games compared. In addition, after an analysis of the mood states depending on gender was performed, the results and therefore the significant differences found, were very similar to those obtained according to group type. Lastly, it was concluded that the type of group (equal, mixed & same gender), and gender were decisive, causing variations in themood states of the students. This provides valuable information for teaching professionals about the structuring and organization of PE sessions, aiming to promoting positive motor experiences

However, while the early stages are the most important for emotional well-being development, research about scientific knowledge of emotional physical education in children is still scarce. The aims of this study were to analyze the intensity of emotions (positive or negative) produced when players took part in games of different social structure, with or without competition (winner or loser), with or without sport experience and to examine the explanations given by the participants for these emotional experiences. Participants (N = 152) were recruited from two Spanish elementary school. We applied Student’s t-test and one-factor ANOVA. Students’ subjective comments were classified through content analysis in macro categories and we used the Chi-square Automatic Interaction Detector (CHAID, implemented in SPSSTM Answer Tree® 13.0). The application of a mixed-methods approach identified statistically significant differences in four variables: (a) the type of emotion, (b) motor domain, (c) type of outcome (winning, losing, and non-competitive), and (d) sport experience. The intensity of positive emotions was higher (M = 3.71, SD = 0.893) than negative emotions (M = 1.18, SD = 0.253, p < 0.001). Furthermore, negative emotions were felt with different intensities (F3 = 3.82, p = 0.011, ES = 0.071), depending on the motor action domain. Comments referring to negative emotions were more frequent in individual games. Winning was associated significantly (p < 0.05) with the highest intensity ratings of positive emotions, whereas losing produced the highest values for negative emotions. The intensity ratings for positive or negative emotions not were different between non-competitive games and competitive games. The sport experience relativizes the mean of emotional intensity, both positive and negative. The present study brings the value of considering games as a key role to promote a physical education addressed to the education of social-emotional well-being in schoolchildren, as the basis of academic training. Furthermore, the results could benefit teachers as well as coaches have scientific input to organize teaching content, generating the desired motor behaviors together with positive experiences

Formación de excelencia y competencia digital: El caso de la mención de pedagogía terapéutica de la UCLM

La atención a la diversidad es sin duda uno de los aspectos más “jóvenes” en el ámbito educativo y más necesario, ya que a través de ella el sistema se vértebra con el fin de poder cubrir las necesidades de un sector de la población cada vez más creciente. Por ello, debemos tomar conciencia de lo importante que es dotar la atención a la diversidad, en sus múltiples facetas, de recursos formativos de calidad. En este trabajo realizamos un análisis del currículo del grado de Educación primaria con mención en Pedagogía terapéutica de la UCLM con el fin de determinar en qué nivel están integradas y adaptadas las competencias digitales recogidas por el INTEF desde el Ministerio de Educación, Cultura y Deporte. Las conclusiones no son nada halagüeñas, ya que la integración de las competencias digitales es muy pequeña, por no decir insignificante. Esto nos lleva a plantearnos la labor de la ANECA y la calidad de los títulos que acredita. ¿Es aceptable una formación superior sin unas competencias digitales solidadas en el s. XXI

Playing equally: Gender role analysis of traditional games in early childhood education: A case study in a school in the Region of Murcia

Todos los contenidos se distribuyen bajo una licencia de uso y distribución Creative Commons Reconocimiento 4.0 (CC BY 4.0).Este estudio busca analizar los roles de género que surgen en los juegos tradicionales en Educación Infantil. Se han encontrado numerosas investigaciones que confirman que los juegos tradicionales poseen en sí roles de género. Por otro lado, el currículo educativo en Educación Infantil y Educación Primaria indica que el juego tradicional es un buen contenido y recurso pedagógico en educación física, un escenario motor donde se producen relaciones sociales de interés para la formación del niño/a y que permite analizar la perspectiva de género en su desarrollo. Apenas se han encontrado investigaciones de esta índole en la etapa infantil. Por ello, el objetivo principal de esta investigación fue analizar si el alumnado de 5 años denotaba roles de género en juegos tradicionales. Dos aulas de Educación Infantil, 28 niñas y 17 niños, fueron observadas durante la puesta en marcha de juegos tradicionales y, posteriormente, sometidas a entrevistas apoyadas en dibujos. Los resultados indicaron los participantes han comenzado a denotar roles de género en los juegos tradicionales. Dichos resultados sugieren que es necesario tener en cuenta estos resultados por parte de las/os docentes la perspectiva de género al aplicar actividades como los juegos tradicionales.This study seeks to analyse the gender roles that emerge in traditional games in early childhood education. Numerous research studies have been found that confirm that traditional games have gender roles. On the other hand, the educational curriculum in infant and primary education indicates that traditional games are a good content and pedagogical resource in physical education, a motor scenario where social relations of interest for the child’s education take place and which allows us to analyse the gender perspective in their development. Very little research of this kind has been found in the infant stage. For this reason, the main objective of this research was to analyse whether 5 year old pupils denoted gender roles in traditional games. Two pre-school classes, 28 girls and 17 boys, were observed during the performance of traditional games and subsequently subjected to interviews supported by drawings. The results indicated that the participants have begun to denote gender roles in traditional games. These results suggest that there is a need for teachers to take a gender perspective into account when implementing activities such as traditional games
