We present the light-curve period analysis of 36 Beta Lyrae stars from the OMC Archive. We check the reference period of the sample by applying the phase dispersion minimization periodogram. From our research, we determine the orbital period of five stars in the sample. One of them is CP Psc, showing a prominent hump in the light curve before the deeper eclipse, and revealing a period of 0.6847936 day. Additionally, we improved the previously published orbital period for 27 stars. Within this sample, we discovered three stars with the O’Connell effect, and we identified a system with a second period known as II Per, with an orbital period of 0.4798512 day and a long period 9.2724776 days. The light curve of V 747 Cen can be reproduced with a dark spot of temperature about 70% its surroundings, which covers one of the poles of the more massive star.

En la industria acuícola, se vienen desarrollando acciones encaminadas a buscar fuentes proteicas alternativas palatables y de alto valor biológico para reemplazar las fuentes convencionales. Debido al potencial nutricional de los subproductos animales, se han adoptado tecnologías para su uso, como las técnicas de bioconversión por hidrólisis enzimática. En consecuencia, el objetivo de este estudio fue obtener y evaluar un concentrado de proteína hidrolizada de residuos animales (CPHRA) como alternativa en dietas para Piaractus brachypomus. Las vísceras de los subproductos avícolas se evaluaron utilizando ácido fórmico y vísceras de trucha al 20% para promover la hidrólisis enzimática a un pH más bajo (pH 3,66). El producto resultante se utilizó en la formulación de dietas para determinar coeficiente de digestibilidad aparente (CDA) de energía y nutrientes, utilizando una dieta control () y tres dietas con inclusión de 10%, 20% y 30% de CPHRA (T1, T2 y T3). Se alimentaron por triplicado ciento veinte juveniles de híbridos de cachama blanca con un peso promedio de 145 ± 3,0 g. La CPHRA presentó alto contenido proteico y se evidenciaron diferencias significativas (p < 0,05) para los CDA de materia seca, proteína bruta, grasa bruta, energía bruta y absorción de cenizas, calcio y fósforo. Los CDA de nutrientes y energía estaban por encima del 80%. En consecuencia, el concentrado de proteína hidrolizada de los desechos de aves de corral tiene un gran potencial como alternativa proteica y energética de alto valor nutricional en la alimentación de los peces.

Background: Visceral Adiposity Index (VAI) has been strongly associated with adipocytokine synthesis, proinflammatory activity, insulin resistance, dyslipidemia, hypertension and atherosclerosis. VAI is a model that includes and correlates anthropometric and metabolic markers and has been proposed as a risk factor index associated with cardiovascular risk in adults. Some studies conducted in pediatric population have extrapolated VAI calculation in order to predict these abnormalities; nonetheless, no adjustment has been done for pediatric ranges in any of the variables included in the formula. The aim of this study was to design a new sex-specific VAI model adjusted for pediatric population. Subjects and methods: Cross-sectional study, 548 children (290 males and 258 females) aged 3-17 years were included for analysis. Eutrophic, apparently healthy children (n = 223) were recruited from 3 public schools located nearby the hospital. Overweight (n = 89) and obese subjects (n = 236) were patients that regularly attend at the Pediatric Obesity Clinic from “Hospital General de México”. Anthropometric evaluation included weight, height, waist circumference (WC). Body mass index (BMI) was calculated and Tg and HDL measured in a 12 hour fasting condition (mMol/L). Results: A non-lineal quadratic regression model accurately explained the relationship between WC and BMI in pediatric population (coefficient of determination R2 = 0.938; p

Resumen En los últimos años ha aumentado el interés por el estudio de la relación entre las variables psicológicas y las lesiones deportivas. Considerando éstas como acontecimientos negativos e inevitables en el contexto deportivo, en el presente estudio abordamos dos disciplinas que tradicionalmente han registrado altas cifras de incidencia, lucha olímpica y taekwondo. Con una muestra de 34 deportistas de ambas modalidades, los resultados más destacados indican puntuaciones similares, aunque algo superiores en todas las escalas del IPED (Inventario Psicológico de Ejecución Deportiva) en los practicantes de taekwondo, si bien no se obtienen diferencias estadísticamente significativas, al igual que en la comparación entre deportistas internacionales y competidores nacionales. El índice de lesión es de 2,42 lesiones por deportista y temporada en lucha, y de 2,60 en taekwondo, y se aprecian diferencias estadísticamente significativas (p< ,01) al comparar a deportistas de nivel nacional (1,90 lesiones) e internacionales (3,46 por temporada). También se obtienen correlaciones significativas entre el número de lesiones y las escalas del IPED Autoconfianza, Control de Afrontamiento Negativo y Control de Afrontamiento Positivo, siendo éstas de signo negativo. Palabras clave: Lesiones deportivas, lucha olímpica, taekwondo, psicología del deporte.

En ellos se han estudiado: a) el tipo de aportación científica; b) el área temática; c) el tipo de muestra utilizada; d) el tipo de deporte o ejercicio físico; e) los tipos de instrumentos utilizados; f) el número de referencias en idioma español; g) el número de referencias en otos idiomas; y h) el número de autores por trabajo.

We study holomorphic maps between C*-algebras A and B, when f:BA(0,ϱ)→B is a holomorphic mapping whose Taylor series at zero is uniformly converging in some open unit ball U=BA(0,δ). If we assume that f is orthogonality preserving and orthogonally additive on Asa∩U and f(U) contains an invertible element in B, then there exist a sequence (hn) in B** and Jordan *-homomorphisms Θ,Θ~:M(A)→B** such that f(x)=∑n=1∞hnΘ~(an)=∑n=1∞Θ(an)hn uniformly in a∈U. When B is abelian, the hypothesis of B being unital and f(U)∩inv(B)≠∅ can be relaxed to get the same statement.

When establishing individual differences in sporting contexts that allow to explain coherently person-sport interaction, should be considered therefore certain individual characteristics (age, gender, personality, cognitives skills, emotionals, etc.) and contextuals (type of sport, level of dedication, etc). At the same time, should be paid attention to those that facilitate a useful information and applicability to sports performance, trying offer direct feedback to the sports practices. Objective. Describe and establish relations between personality signals and contextuals situations regarding make decisions in sport practice. Method. A study was done with a random sample of athletes (N = 623) between 16 and 50 years old, using personality (BFQ) and make decisions (CETD) questionnaires. Results. Perseverance is shown as the most characteristics indicator of sample; women indicate highest rates in personality dimensions, least in control emotions and openness to culture. Professional athletes differ significantly in dominance and perseverance with respect to athletes amateurs, and those who practice individual sports point significantly better control emotions that those who practice sports colective, that indicate highest significantly in cordiality. Also, women indicate significantly worst rates in anxiety and perceived competence in make decisions. Conclusions. Results allow confirm the hypothesis raised, emphasizing above all that as levels increased of cordiality and cooperation, reduce levels of commitment decisions, allowing more in team sports association.

Background: Environmental stressors require the professional diver to undergo a complex process of psychophysiological adaptation in order to overcome the demands of an extreme environment and carry out effective and efficient work under water. The influence of cognitive and personality traits in predicting underwater performance and adaptation has been a common concern for diving psychology, and definitive conclusions have not been reached. Method: In this ex post facto study, psychological and academic data were analyzed from a large sample of personnel participating in scuba diving courses carried out in the Spanish Navy Diving Center. In order to verify the relevance of individual differences in adaptation to a hostile environment, we evaluated the predictive validity of general mental ability and personality traits with regression techniques. Results: The data indicated the existence of psychological variables that can predict the performance (R2 = .30, p<.001) and adaptation (R2N = .51, p<.001) of divers in underwater environment. Conclusions: These findings support the hypothesis that individual differences are related to the probability of successful adaptation and effective performance in professional diving. These results also verify that dispositional traits play a decisive role in diving training and are significant factors in divers' psychological fitness. [ABSTRACT FROM AUTHOR]

A review of the Athlete Burnout Inventory (ABI) offers an improved version of the first measurement tool of the syndrome that was used in our country. The ABI, which has made it possible to further knowledge of burnout from both a research and applied perspective, required best statistical fits which, among other issues, would ensure the best possible measurement of this psychological problem in athletes. The present state of the measurement of burnout appears in the introduction, reviewing its evolution. The basic characteristics of the 460 athletes forming the sample are described, in the section on methodology, and throughout the section on results, we find a series of psychometric indicators that lead us to be optimistic as to the developments achieved with ABI-R, as well as the burnout measurement it offers through its three dimensions: Emotional Exhaustion, Depersonalization, and Reduced Sense of Personal Accomplishment.

This article summarizes the current situation of one of the most important XXI century epidemics. The high rates of obesity in all countries and specially in our country at early ages are worrying. Traditionally, investigations have focused on the most nutritional aspects, such us dietary factors, metabolism, calory intake and energy expenditure. However, other sciences -such as Psychology-point out new influencing factors, such as food addiction, depression, stress and anxiety. In this piece of work, more than 80 articles from all disciplines and different databases and related to obesity are analyzed, as well as a new theoretical approach is proposed to ensure a more accurate comprehension. The literature review shows the necessary evidence to introduce a new model of obesity named edorexia, and raise issues to be resolved in future research oriented from a multidisciplinary perspective.

Optimism is considered a relevant parameter in sport performance and this study aims to analyse its effects in adverse circumstances. In this study, 66 swimmers (boys and girls) with an average age of 13.66 completed the same test at two different times, After the first test, they received negative feedback (a higher than real time) in order to check the effects on the second test. The results of this study were expected to replicate the study published by Seligman at Berkeley University in 1990. Interestingly, after such negative feedback, pessimists showed significant differences between the first and second tests. In contrast, although not statistically significant, our results indicate that all the swimmers whose performance improved in the second test had optimistic profiles. Finally, we discuss the use of evaluating and providing training in optimism for enhanced performance in competitive sports. [ABSTRACT FROM AUTHOR]

Because the consequences of aggression can be very serious, in this work we have analysed the influence of different personal, social, educational and family related variables on the development of deviant and aggressive behaviors among adolescents. Based on a sample of 1.800 participants, we analysed whether there were gender and age differences in these variables. The group of boys obtained higher scores on school and social maladjustment, and antisocial and criminal behavior. In addition, they received a more protective education on behalf of their mothers. The group of girls reported greater family dissatisfaction and a more restrictive education. From the age of 13, teenagers report higher personal, school and social life maladjustment. They receive a more restricted and less personalized and permissive educational style from their parents. This educational style may increase the risk of aggressive, antisocial and criminal behaviour in teenagers. [ABSTRACT FROM AUTHOR]

This article describes a study conducted on the Valencian Petanque Federation's regional team during the 2008 National League. Each Autonomous Region in Spain sends a team to compete in the "all against all" category in this league, which takes place over an entire weekend in May 2008. This methodology requires applied and systematic work, not only inside, but also outside the context of sports. At the same time, we achieved goals during this intervention such as: taking advantage of support and boosting confidence to improve self-perception; increasing self-confidence; and even stimulating curiosity to focus attention, motivation and the orientation of thoughts on very specific objectives appropriately. The intervention achieved all this through a detailed cognitive-conductual study that is described in this paper. This psychological training plan may be considered a quick procedure. Furthermore, it can also be applied in concrete interventions, close to the time of main competitions or even shorts competitions; however, the most common application is after a period of learning and adaptation to psychological work in high performance sports.

A new diffusion model based on kinematic properties and supported by Metropolis Monte Carlo free energy minimization and density functional theory calculations is proposed in this work. This new mechanism breaks the isotropic features of random adatom diffusion over a single crystal surface, not only about the main directions but also about the sense of movement. The present model allows us to understand all the anomalous growing features characterizing the behaviour of an insulator film, such as aluminum fluoride, over a metallic Cu(1 0 0) single crystal surface. The growth process of this system is characterized by several non-fully understood features, including a large diffusion coefficient, sticking at both sides of steps, and island atomistic arrangement along special directions. Although we focus our analysis on the AlF3/Cu(1 0 0) system, our conclusions may be extended to the diffusion of other complex molecules over different surfaces. [ABSTRACT FROM AUTHOR]

AimA series of knowledge has been developed on burnout syndrome in the sports context that has allowed to generate a solid theoretical structure that requires new contributions to delve into those aspects that have been less addressed, as is the case of optimism and resilience when it comes to linking them to the syndrome in top-performance athletes. For this purpose, the Burnout Inventory for Athletes (IBD-r), the Resilience Scale adapted to Spanish, and the Life Orientation Scale-Revised (LOT-R) for optimism were used.MethodsFrom this perspective, the study was approached with 121 Uruguayan athletes who participated in the last Pan-American Games, assuming practically all the subjects who have this level of sport (142) considering gender and type of sport.ResultsThe results indicate that 67% of the sample presents burnout symptoms for the emotional exhaustion dimension, and moderate resilience and optimism. Although there are no significant differences attributable to gender or type of sport, this contribution allows us to continue focusing on future work and further analysis. The type of sport presented statistically significant differences in relation to the personal competence dimension and the type of sport.ConclusionResilience and optimism obtained a clear influence on the occurrence of burnout, in a statistically negative sense, showing themselves as interesting prevention strategies for future lines of research, where it is essential to design interventions that teach emotional skills to manage adversity and prevent burnout.

An approach to the psychological profile of vulnerability to the injury of the athlete has become necessary in competitive sports. Subjects consisted of a total of sample were 285 males (23 non-injured) and 168 females (24 non-injured). The male athletes had an average age of 21.77 years and the female athletes of 20.55 years. The sample consisted of athletes of individual sports (tennis, athletics and swimming) and players of team sports (football, basketball and handball) belonging to different sports clubs in the Valencian Community. A Sport Competitive Anxiety Test (SCAT) was used for the evaluation of competitive anxiety; an EPR scale was used to evaluate hardiness; a Competitiveness-10 scale was used to assess competitiveness; and a specific registration form was used for the assessment of injury. The study was carried out basing on a quantitative methodology. The design of the study was observational, descriptive and correlational. The study was based on the hypothesis: the number of injuries will increase with lower levels of hardiness and success-oriented motivation, and higher levels of competitive anxiety and motivation addressed to avoid failure. The objective was to analyze the differences in the number of injuries among athletes who had a profile of vulnerability to injury (low hardiness, high competitive anxiety, low motivation for success and high motivation oriented to avoid failure) against those who did not fit that profile. According to the theoretical foundation, those placed in this profile would be more susceptible to injury. However, the results of the study indicate that men with a profile of vulnerability to injury (who should sustain more injuries) suffered fewer moderate injuries, and the total number of injuries and rate of injury were lower. Results are discussed and some conclusions of the study are indicated. [ABSTRACT FROM AUTHOR]

In ultra-high vacuum systems, obtaining the composition of a mass spectrum is often a challenging task due to the highly overlapping nature of the individual profiles of the gas species that contribute to that spectrum, as well as the high differences in terms of degree of contribution (several orders of magnitude). This problem is even more complex when not only the presence but also a quantitative estimation of the contribution (partial pressure) of each species is required. This paper aims at estimating the relative contribution of each species in a target mass spectrum by combining a state-of-the-art machine learning method (multilabel classifier) to obtain a pool of candidate species based on a threshold applied to the probability scores given by the classifier with a genetic algorithm that aims at finding the partial pressure at which each one of the species contributes to the target mass spectrum. For this purpose, we use a dataset of synthetically generated samples. We explore different acceptance thresholds for the generation of initial populations, and we establish comparative metrics against the most novel method to date for automatically obtaining partial pressure contributions. Our results show a clear advantage in terms of the integral error metric (up to 112 times lower for simpler spectra) and computational times (up to 4 times lower for complex spectra) in favor of the proposed method, which is considered a substantial improvement for this task.

Introducción: La falla cardiaca es un problema de salud pública, genera grandes costos al sistema de salud por las readmisiones hospitalarias y genera morbimortalidad en los pacientes. Objetivo: Evaluar el impacto en la clase funcional, las visitas al servicio de urgencias y las readmisiones hospitalarias en la población de pacientes atendidos en el programa de falla cardiaca de un centro de referencia cardiovascular en Colombia. Metodología: Estudio de cohorte retrospectivo y prospectivo. Se realizó un análisis de las características clínicas y demográficas de los pacientes un año antes y después de ingresar al programa de la falla cardiaca. Resultados: Se incluyeron 511 pacientes, con una edad promedio de 66,4 ± 14,3 años, 58,7% de sexo masculino. Se realizó seguimiento en un programa de la falla cardiaca en el cual se contó con los controles por cardiología y enfermería, rehabilitación cardiaca, asistencia a un programa educativo y apoyo por psicología. Luego de 18 meses de seguimiento se demostró un incremento estadísticamente significativo en la fracción de eyección en la clase funcional, se disminuyeron las consultas a urgencias en un 29,3%, las rehospitalizaciones en un 66,8% y la duración de estas en un 37,5%. La mortalidad total fue del 4%. Conclusión: El seguimiento multidisciplinario en programas de la falla cardiaca es factible en Colombia, mejorando la clase funcional, la fracción de eyección y disminuyendo los ingresos hospitalarios y las visitas al servicio de urgencias.

El presente artículo resume la situación actual de una de las epidemias del siglo XXI más importantes, la obesidad. Las altas tasas de obesidad de todos los países y especialmente en edades tempranas en nuestro país son preocupantes. Tradicionalmente, las investigaciones se han centrado en los aspectos más nutricionales, como factores dietéticos, metabolismo, aporte calórico y gasto energético. Sin embargo, otra disciplina como la psicología halla nuevos factores que influyen, como la adicción a la comida, la depresión, el estrés y la ansiedad, entre otros. En este trabajo, se analizan más de 80 artículos de todas las disciplinas relacionadas con la obesidad, obtenidos en diferentes bases de datos y, así mismo también se plantea un nuevo enfoque de carácter teórico para una mayor comprensión. Los estudios de la búsqueda bibliográfica realizada demuestran las evidencias necesarias para introducir un nuevo concepto de obesidad denominado edorexia y plantear cuestiones que deberán ser resueltas en futuras investigaciones centradas en una perspectiva multidisciplinar.This article summarizes the current situation of one of the most important XXI century epidemics.

Este estudio pretende analizar la literatura científica publicada referente a los efectos cognitivos de la actividad física en personas con enfermedad de Alzheimer (EA). Se buscaron artículos que trataran principalmente los efectos cognitivos de la actividad física en personas con EA, encontrando finalmente 35 artículos. En cuanto a la evolución temporal, se observa una tendencia creciente de publicaciones con el paso de los años. Cabe destacar la gran variedad y heterogeneidad de autores principales y revistas. Geográficamente, los países con mayor número de publicaciones son Estados Unidos y Brasil, destacando sobre el resto. Teniendo en cuenta estos resultados, podemos concluir que el estudio de los efectos en aspectos cognitivos y propios de la enfermedad propiciados por la actividad física es un campo de estudio relativamente nuevo en el que debemos profundizar.

Los estudios bibliométricos son de primordial relevancia en el marco de la evaluación de los contenidos científicos. Al mismo tiempo, son de gran utilidad al permitir una aproximación detallada al objeto de análisis así como a los datos que ofrecen sobre un área de conocimiento determinado. En este estudio se presenta una revisión del trabajo científico publicado, hasta el año 2011, sobre burnout y optimismo en el ámbito deportivo para conocer el estado de la cuestión de estas variables. La búsqueda se ha realizado a través de las bases de datos electrónicas, PsycINFO y SCOPUS. Una vez seleccionados los documentos, la información obtenida a través de su lectura se recogió en una matriz creando una base de datos que incluía los datos pertinentes. Finalmente se analizó la información más relevante: número de artículos publicados, autores que participan en cada uno de los trabajos, distribución geográfica, centros de investigación, tipo de publicación, revistas científicas, metodología, variables relacionadas e instrumentos utilizados. Los resultados del estudio confirman el aumento de trabajos sobre burnout y optimismo como constructos dentro de las investigaciones de psicología de la actividad física y el deporte.

Frailty is a common condition in older adults that negatively impacts health and quality of life. This study evaluated a comprehensive, personalised, and coordinated intervention under the value-based care approach to address frailty's multidimensional nature in older people in the primary care setting. It employed a pre-post randomised controlled design involving 242 frail individuals aged over 65 years living in the community in Valencia (Spain) between 2021 and 2023. Assessments were conducted at baseline, 12 months (immediately post-intervention), and 18 months. The intervention included a personalised care plan supported by technology, with monthly motivational follow-ups and plan updates by health professionals and participants. Outcomes were measured using an assessment questionnaire that included the International Consortium for Health Outcomes Measurement dataset for the older population: physical health, physical functioning, general mental health, satisfaction with social activities and relationships, ability to carry out usual social roles and activities, pain, general quality of life, loneliness, physical frailty, psychological frailty, and social frailty. The study found significant improvements in physical frailty, quality of life, reduced health resource use and hospitalisations and lower levels of pain and depression/anxiety compared to baseline. The findings suggest further research into value-based care approaches, emphasizing the development and activation of personalised, comprehensive programs for older individuals with frailty.

With ageing, the risk of frailty increases, becoming a common condition that exposes older people to an increased risk of multiple adverse health outcomes. In Valencia (Spain), the ValueCare project develops and applies a value-based care approach that addresses the multidimensional nature of frailty by implementing integrated and personalized care to tackle psychosocial frailty. A pre-post controlled design with a baseline measurement at inclusion, at the end of implementation and a follow-up measurement after 6 months of intervention. In Valencia (Spain), 120 participants over 65 years of age are recruited from primary care centres to receive the ValueCare comprehensive and personalised care plan according to the results and are compared with 120 participants receiving "usual care". An assessment questionnaire is designed using validated instruments, and a personalised care plan is developed specifically for each participant based on the results obtained. The study protocol has been registered under the ISRCTN registration number ISRCTN25089186. Addressing frailty as a multidimensional and multifactorial risk condition requires the development and implementation of comprehensive assessments and care. In this context, this study will provide new insights into the feasibility and effectiveness of a value-based methodology for integrated care supported by ICT for older people experiencing frailty.

Frailty is one of the most challenging issues among older adults, and the relationship between frailty and falls has already been assessed numerous times in literature. In the present study, we explored the mediating role of self-efficacy related to falls (FSe) in the relationship between frailty and fall risk. In a cross-sectional design, 1080 community-dwelling older adults from Rotterdam (Netherlands) and Valencia (Spain) completed a questionnaire and data were then analyzed via mediation analysis using a bootstrapping approach. Results show that higher frailty is associated with higher fall incidence, and higher FSe is a partial mediator of this association, with a confidence interval for the indirect effect of 0.131-0.247. Moreover, results showed gender differences in FSe levels; women had lower FSe scores. Deepening research on the construct of FSe may give potential explanations that account for the emerged gender differences, and it could be more targeted in fall prevention programs., Competing Interests: Declaration of conflicting interestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: The coronavirus disease 2019 (COVID-19) pandemic has impacted healthcare guidelines and modalities of patient consultation worldwide. The frequent cycles of quarantine confinement in Chile have caused mobility restrictions for patients and physicians, forcing the Hospital Las Higueras de Talcahuano (HHT) to replace the assisted televisit modality with a more classic televisit program. Here we have described if this change in televisit modality and type of outpatient may have impacted patients' satisfaction., Methods: The patient's perception of satisfaction was evaluated through self-administered survey questionnaires previously validated in Spanish. Cohorts were grouped according to the following two relational models: (i) assisted televisit, 503 neurology patients from 2018 to 2019, and (ii) televisit, 831 patients from different specialties treated during 2020. Perception of satisfaction was compared by gender, age, and type of televisit, and internal consistency (Cronbach alpha) and reliability (factorial analysis of principal components) were assessed. Finally, we compared the patient satisfaction of both modalities., Results: Questionnaires showed excellent internal consistency; all items showed point biserial correlations greater than 0.30. Assisted televisit and televisit cohorts comprised 64.2% and 67.6% females, respectively, and patients under the age of 65 years were 62.2% and 75%, respectively. Assisted televisit patients showed very high 94.4% (n=475) and high 5.2% (n=26) satisfaction levels, while televisit patients showed very high 22.3% (n=185), high 63.9% (n=531), and moderate 13.1% (n=109) satisfaction levels; this difference was statistically significant at p<0.001., Conclusion: Lower perception of satisfaction due to the change in televisit relational modality underscores the importance of primary care professionals who support the specialist in the assisted televisit model. However, the televisit modality showed high patient satisfaction and suggested that this modality can be a plausible alternative according to each location's reality. The results of this study indicate that both assisted televisit and televisit contribute to delivering an integrative solution that helps to alleviate the system's fragmentation., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Constanzo et al.)
