    Purpose of review The pharmacological treatment of patients with epilepsy and psychiatric comorbidities may sometimes represent a therapeutic challenge. This review is focused on the pharmacological management of patients with epilepsy and psychiatric problems in terms of rationalization of the antiepileptic drug (AED) treatment and the pharmacological management of the most clinically relevant psychiatric comorbidities, namely mood and anxiety disorders, psychoses, and attention deficit hyperactivity disorder (ADHD). Recent findings Up to 8% of patients with drug-resistant epilepsy develop treatment-emergent psychiatric adverse events of AED regardless of the mechanism of action of the drug and this is usually related to an underlying predisposition given by the previous psychiatric history and the involvement of mesolimbic structures. Careful history taking, periodic screening for mood and anxiety disorders, low starting doses, and slow titration schedules can reduce the possibility of AED-related problems. A pragmatic checklist for the pharmacological management of patients with epilepsy and psychiatric disorders is presented. Summary patients should be informed of potential behavioral effects of AEDs but no drugs should be excluded a priori. Any psychiatric comorbidity should be addressed in the appropriate setting and full remission and recovery should always represent the first goal of any therapeutic intervention. Neurologists should be aware of the side effects of major psychotropic drug classes in order to fully counsel their patients and other health professionals involved

    Introduction: The purpose of this study was to find out the effect of task organization and different game situations on intensity and of repetitions in basketball. Method: A quasi-experimental design with twelve players group of 12, 4 ± 0, 7 years-old average was done. Three training sessions about lay-up was realized. The independent variables were task organization and different game situations. The dependent variables were heart rate and number of repetitions, and player´s perception about intensity and work. Results: a) statistically significant differences in heart rate between the status of 1x0 and 2x2 (p =. 014), and trends towards significance between the situation of game 1x0 and 3x3 (p =. 065), b) were statistically significant differences in heart rate between the situation frequents gaming 1x0 circuit on the rows (p =. 027) and forms involving simultaneous moves (p =. 000), and the game situation 1x1 between rows with respect to the ways games with simultaneous participation (p =. 014); c) The effect of the interaction between the game situation factor and type of organization was statistically significant (F6, 42 = 9,256, p =. 000 ). Are statistically significant differences in the number of operations performed by the players on the combination of the four game situations and the three types of organization. Conclusions: a) The groups in circuits had a greater number of repetitions and intensity perceived, b) the groups in games through forms showed greater heart rate and more repetitions, and c) the group in rows presented no value to excel regard to the task structure. From the collected data, it is deduced that depending on which are the objectives of the sports abilities, will be more useful adapted to use a type of organization or another one.Introducción: El presente trabajo analiza la influencia de diferentes formas de organización y situaciones de juego sobre la intensidad y el número de intervenciones en baloncesto. Método: Se realizó un diseño cuasi-experimental, con 12 jugadores de edad 12,4 ± 0,7, años. Se realizaron tres sesiones de intervención sobre el lanzamiento a canasta en carrera (entrada a canasta). Las variables independientes fueron la forma de organización y las diferentes situaciones de juego. Las variables dependientes fueron la frecuencia cardiaca media, el número de intervenciones de lanzamientos, y la percepción de la intensidad de trabajo de los jugadores. Resultados: a) se observan diferencias estadísticamente significativas en frecuencia cardiaca entre la situación de 1x0 y la de 2x2 (p=.014), y tendencias a la significación entre la situación de juego de 1x0 y la de 3x3 (p=.065), b) Se aprecian diferencias estadísticamente significativas en frecuenta cardiaca entre la situación de juego de 1x0 en circuito con respecto a las filas (p=.027) y las formas jugadas con participación simultanea (p=.000), y en la situación de juego de 1x1 entre filas con respecto a las formas jugadas con participación simultanea (p=.014); c) El efecto de la interacción entre el factor situación de juego y tipo de organización fue estadísticamente significativo (F6,42 = 9.256, p=.000). Se aprecian diferencias estadísticamente significativas en el número de intervenciones realizadas por los jugadores en la combinación de las cuatro situaciones de juego y los tres tipos de organización. Conclusiones: a) La organización grupal con participación simultánea mediante circuitos presentó mayor número de intervenciones e intensidad percibida; b) la organización grupal con participación simultánea mediante formas jugadas con participación simultanea mostró mayor frecuencia cardiaca y más intervenciones; y c) la organización grupal con participación alternativa mediante filas no presentó ningún valor que sobresalga respecto a las formas de organización. A partir de los datos obtenidos, se deduce que dependiendo de cuáles sean los objetivos de la habilidad deportiva, será más adecuado utilizar un tipo de organización u otro

    The Mediational Role of Desire for Cultural Tightness on Concern With COVID-19 and Perceived Self-Control

    When ecological threats are more severe or prevalent, societies are more likely to tighten their social norms and punishments. Moreover, when people follow clear and tight rules, they are more prone to regulate their behavior (i.e., self-control) in order to avoid punishment. Therefore, we examined the mediating role of people’s endorsement of cultural tightness (i.e., support and desire) on the relationship between concern with COVID-19 threat and personal self-control. Our hypothesis was tested through a mediation model in two studies with a sample of (N=315, 77.1% females, Mage=23.71) university students (Study 1) and with a heterogeneous sample of (N=239, 65.7% females, Mage=36.55) participants (Study 2). Empirical support for the proposed model was found in both studies. Implications of this research will be discussed. The main implication is related to the possibility that people’s desire for strong norms to cope with the COVID-19 threat could promote greater self-regulated preventive behavior in order to protect their health

    Nutrition, bioenergetics, and metabolic syndrome

    According to the World Health Organization (WHO), the global nutrition report shows that whilst part of the world's population starves, the other part suffers from obesity and associated complications. A balanced diet counterparts these extreme conditions with the proper proportion, composition, quantity, and presence of macronutrients, micronutrients, and bioactive compounds. However, little is known on the way these components exert any influence on our health. These nutrients aiming to feed our bodies, our tissues, and our cells, first need to reach mitochondria, where they are decomposed into CO2 and H2O to obtain energy. Mitochondria are the powerhouse of the cell and mainly responsible for nutrients metabolism, but they are also the main source of oxidative stress and cell death by apoptosis. Unappropriated nutrients may support mitochondrial to become the Trojan horse in the cell. This review aims to provide an approach to the role that some nutrients exert on mitochondria as a major contributor to high prevalent Western conditions including metabolic syndrome (MetS), a constellation of pathologic conditions which promotes type II diabetes and cardiovascular risk. Clinical and experimental data extracted from in vitro animal and cell models further demonstrated in patients, support the idea that a balanced diet, in a healthy lifestyle context, promotes proper bioenergetic and mitochondrial function, becoming the best medicine to prevent the onset and progression of MetS. Any advance in the prevention and management of these prevalent complications help to face these challenging global health problems, by ameliorating the quality of life of patients and reducing the associated sociosanitary burden

    Palm kernel cake (PKC) proteins were hydrolysed in the presence of seven proteolytic enzymes. The antioxidant and antihypertensive activities of each protein hydrolysate were evaluated. Papain-generated protein hydrolysate showed the highest antioxidant effects measured by radical scavenging activity (65%), iron (Fe)(II)-chelating activity (65%), and antihypertensive activity (71%). The results revealed a strong correlation between the antioxidant activity of the protein hydrolysates with angiotensin-converting enzyme (ACE) inhibitory activity (R2 = 0.69 - 0.98), except for trypsin-generated hydrolysate (R2= 0.22). The most potent protein hydrolysate was fractionated and profiled using reversed-phase high-performance liquid chromatography and isoelectric focusing; peptides were subsequently isolated and identified by tandem mass spectrometry. The individual peptides were evaluated for antihypertension potential. A positive correlation was identified between radical scavenging activity and Fe(II)-chelating activity together and ACE inhibitory activity with R2 = 0.69 - 0.98. The findings indicate that there was a positive relationship between the antioxidant and antihypertensive activities of protein hydrolysates and bioactive peptides from PKC proteins

    [EN] This paper presents a decision support system to simultaneously solve the supply network configuration problem and the operations scheduling problem for the machine tool industry. A novel database structure, which is able to consider alternative operations and alternative bills of material, has been used. An algorithm for complete enumeration to determine all the feasible solutions using stroke graphs is introduced. A multiagent-based simulator evaluates the different key performance indicators that the supply network deals with for each alternative solution (e.g. workload, profits, delivery times, etc.) to determine that ‘satisficed’ by the collaborative decision-making among its members. A case study based on a Spanish company that assembles highly customised machines and tools in several European plants is considered. From the experiments results based on data linked to this industry, it will be demonstrated that the tool is potentially useful for stakeholders and for the central decision-maker to make decisions collaboratively in a multisite context caseWe thank the EWG-DSS and their four expert anonymous referees as well as the guest editorial board for their useful suggestions and criticism on earlier versions of this paper.

    Polyamines as an ecofriendly postharvest tool to maintain fruit quality

    Get PDF
    Polyamines (PAs) are natural compounds involved in a wide range of plant growth and developmental process, such as cell division, dormancy breaking, germination, development of flower buds, fruit set, growth and ripening, as well as in plant responses to environmental stresses including chilling injury. This chapter will focus on the role of PAs in fruit growth and ripening, with special emphasis on the effects of pre- and postharvest PA treatment on fruit quality attributes, bioactive constituents with antioxidant activity, and tolerance of fruit to chilling injury damage. The results of this chapter provide evidence for the numerous beneficial effects of the exogenous PA treatments, both at pre- and postharvest time in fruit quality attributes including their concentration in antioxidant compounds. Taking into account that PAs are naturally occurring molecules their application as pre- or postharvest treatment could be considered as an environmentally compatible tool as they can be metabolized by fruit cells. In addition, it should be pointed out that although exogenous application of PAs enhances their endogenous levels, the concentrations remain far lower than the toxic ones. Since modern agriculture is searching for effective biological molecules with well-known metabolic effects but without toxicological effects, a possible answer may be related to PA treatments

    A Parallelizable Heuristic for Solving the Generic Materials and Operations Planning in a Supply Chain Network: A Case Study from the Automotive Industry

    Full text link
    [EN] A trend in up-to date developments in multi-site operations planning models is to consider in details the different ways to produce, buy or transport products and the distributed decision-making process for operations planning. One of the most generic approaches to support global optimization in those supply chain networks by considering all the different operations alternatives and product structures is the Generic Materials & Operations Planning Problem. This problem can be modelled by a Mixed Integer Linear Programming model capable of considering production, transportation, procurement tasks and their alternatives and other relevant issues such as packaging. The aim of this paper is to introduce the implementation of a parallelizable heuristic method for materials and operations planning and its application to a case of a Supply Chain Network of the automotive industry. The approach uses variants of the GMOP model to overcome traditional MRP systems' limitations.Maheut ., JP.; García Sabater, JP. (2013).

    Hidratació i rendiment: pautes per a una elusió efectiva de la deshidratació per exercici

    Get PDF
    El rendiment de les capacitats físiques i mentals durant la pràctica esportiva o la competició, es troba disminuït sota condicions de deshidratació. La pèrdua de pes es deu a la pèrdua d’aigua (suor i respiració) i quan aquesta és important, afecta de manera decisiva els sistemes nerviós, cardiovascular, termoregulador, endocrí i/o metabòlic, i pot provocar fins i tot la mort. Per eludir aquests efectes negatius de la deshidratació així com la disminució del rendiment, l’atleta haurà de beure prou quantitat de líquid abans, durant, i després de la competició o la pràctica d’exercici. Idealment, la beguda serà una solució composta d’aigua, electròlits i carbohidrats, en quantitat adequada per garantir, d’una banda, un rendiment òptim durant la competició i, d’una altra, reposar eficaçment i completament les pèrdues hídriques, electrolítiques i energètiques. La composició i el volum de la beguda tindrà en compte els factors extrínsecs (temperatura, humitat, altitud, vent, etc.) que envolten la competició, els factors intrínsecs de l’atleta (nivell de deshidratació, problemes gastrointestinals, tipus de competició) i les pròpies característiques de la beguda (gust, temperatura, composició). En termes generals, els atletes no acostumen a beure, durant la pràctica esportiva, el volum necessari per reemplaçar la pèrdua de fluids i electròlits, cosa que fa que calgui establir pautes perquè ho facin. En aquest treball es presenten aquestes pautes i la base fisiològica que les sosté
