Estado nutricional y condición física en personas mayores activas vs. Sedentarias / Nutritional Status and Physical Condition in Active vs. Sedentary Elderly People

El objetivo del estudio fue conocer la relación entre el estado nutricional, la adherencia a la dieta mediterránea y el nivel de condición física de personas mayores. Participaron 168 personas mayores de 65 años (grupo control=84 personas activas y grupo experimental=84 personas sedentarias). La adherencia a la dieta mediterránea fue medida con el cuestionario MEDIS-FFQ, el nivel de práctica de actividad física mediante una pregunta creada a tal efecto, y las diferentes pruebas físicas con los instrumentos específicos. Los resultados revelaron que el 63.1% manifestó baja adherencia a la dieta mediterránea y el 34.5% alta, teniendo los sujetos sedentarios mayor adherencia que los activos (p≤0.05; 46.4% vs. 22.6%). Los sujetos activos tienen mejor condición física que los sedentarios (p≤0.001). Por tanto, la mayor parte de las personas mayores deben incrementar su adherencia a la dieta mediterránea y la práctica de actividad física como mecanismo de mejora de su salud

The objective of the study was to know the relationship between nutritional status, adherence to the Mediterranean diet and the level of physical displacement of older people. 168 people older than 65 years participated (control group = 84 active people and experimental group = 84 sedentary people). Adherence to the Mediterranean diet was measured with the MEDIS-FFQ questionnaire, the level of physical activity practice through a question created for that purpose, and the different physical tests with the specific instruments. The results revealed that 63.1% showed low adherence to the Mediterranean diet and 34.5% high, according to the sedentary subject's greater adherence than the active ones (p≤0.05, 46.4% versus 22.6%). Active subjects have better physical income than sedentary people (p≤0.001). Therefore, most elderly people want to increase their adherence to the Mediterranean diet and the practice of physical activity as a mechanism to reduce their health

Influencia táctica del resultado parcial en los saques de esquina en fútbol / Influence of match status on corner kicks in elite soccer

El propósito del estudio es analizar como la variable situacional resultado parcial puede afectar al comportamiento táctico-estratégico en los saques de esquina en fútbol. Se han estudiado 902 saques de esquina realizados en 95 partidos correspondientes a la UEFA Euro 2012, y Fase Final de la FIFA World Cup 2010. Para identificar las interacciones se utilizó el método de crecimiento Chi-square automatic interaction detector (CHAID), que nos ha permitido identificar tres modelos: con el resultado de empate en los últimos minutos de juego, el equipo atacante incorpora al remate entre 2 a 5 jugadores y el equipo rival sitúa 1 ó 2 jugadores bajo palos. Ganando en los últimos minutos del encuentro, el equipo sitúa también entre 2 a 5 jugadores en ataque y el rival no defiende bajo palos. Perdiendo en los últimos minutos del encuentro, el equipo atacante incorpora a 6 o más jugadores al ataque (AU)

The aim of this study was to examine the effects of the situational variable match status on corner kicks performance indicators in 95 matches played during the final stages of the 2012 UEFA European Championships and the 2010 FIFA World Cup. Video recordings of the matches were analyzed and coded post-event using notational analysis. Multiple interactions between the performance indicators and match status were analyzed using the Chi-squared automatic interaction detection (CHAID) decision-tree method. The results show that when a corner kick is taken during the last 30 minutes of the match, teams that are losing place 6 or more attackers in the shooting area, while teams that are drawing place 2-5 attackers in this area. In the same situation, teams that are drawing place 1-2 defenders at the goalposts while winning teams place none (AU)

Análisis descriptivo y comparativo de los saques de esquina. UEFA Euro 2012 / Análise descritiva e comparativa das cobranças de escanteios. UEFA Euro 2012 / Descriptive and comparative analysis of the corners. UEFA Euro 2012

Objetivo. Alcanzar un conocimiento más profundo (y con el soporte empírico adecuado) de los saques de esquina en el fútbol de máximo nivel. Se pretende conocer la incidencia real de este tipo de acciones durante los partidos, así como describir cuáles son las prácticas habituales. A continuación, se pretende identificar aquellas variables que puedan estar asociadas a la eficacia de estas acciones. Método. Se plantean dos tipos de aproximaciones complementarias en el análisis de los datos: una de carácter univariada, y otra bivariada. A nivel univariado se trata de describir cuáles son las características de la ejecución de estas acciones (número, forma de ejecución…). A nivel bivariado, mediante la realización de tablas de contingencia (acompañadas del contraste Chi-cuadrado y medidas de asociación) se intentará identificar aquellas variables que puedan estar asociadas a la eficacia alcanzada. Resultados. Después del registro de 345 saques de esquina ejecutados durante la Eurocopa 2012, los resultados indican una baja eficacia en el remate de este tipo de acciones. En cambio, los goles que proceden de saque de esquina sí presentan una transcendencia importante en el resultado final. Para alcanzar el éxito en este tipo de acciones, deben intervenir entre tres y cuatro atacantes y producirse una organización ofensiva dinámica. Conclusiones. Los datos empíricos disponibles han puesto en valor la necesidad de un trabajo táctico más refinado de estas acciones, basado en asociaciones entre los jugadores y movimientos de engaño (AU)

Objetivo. Chegar a um conhecimento mais profundo (e com suporte empírico adequado) das cobranças de escanteios no futebol de alto nível. Destina-se a determinar a incidência real deste tipo de ação durante as partidas, assim como descrever quais são as práticas habituais. A seguir, se pretende identificar as variáveis que podem estar associados com a eficácia destas ações. Método. Surgem dois tipos de abordagens complementares na análise de dados: uma de caráter univariada e outra bivariada. A univariada trata-se de descrever quais são as características da execução destas ações (número, forma de execução …). A bivariada, mediante a realização de tabelas de contingência (acompanhada do contraste qui-quadrado e medidas de associação) tentará identificar as variáveis que podem estar associados com a eficiência alcançada. Resultados. Após o registro de 345 cobranças de escanteios executadas durante a Eurocopa 2012, os resultados indicam uma baixa eficiência na finalização de tais ações. Entretanto, os objetivos que precedem de cobranças de escanteios têm uma transcendência importante no resultado final. Para alcançar sucesso neste tipo de ação, devem intervir entre três e quatro atacantes e produzir uma organização ofensiva dinâmica. Conclusões. Os dados empíricos disponíveis foram postos em valor a necessidade de um trabalho tático mais refinado destas ações, baseados em associações entre os jogadores e os movimentos de engano (AU)

Objective. Reaching a deeper knowledge (and with proper empirical support) of the corners in the top-level football. It is intended to determine the real impact of this type of actions during matches and describe what the current practices are. Then, it is intended to identify those variables that may be associated with the effectiveness of these actions. Method. Two complementary approaches arise in the analysis of data: one univariate and other bivariate. At univariate level, it comes to describe what are the characteristics of the execution of these actions (number, form of execution…). At bivariate level, by making contingency tables (accompanied by Chi-square contrast and association measures) it will try to identify those variables that may be associated with the achieved efficiency. Results. After registration of 345 corners executed during Euro 2012, the results indicate a low efficiency in the auction of such actions. Instead, the goals coming from corner have an important significance in the final result. To succeed in this kind of actions should intervene between three and four attackers and a dynamic offensive organization should occur. Conclusions. The empirical data available have been worth the need for a more refined tactical work of these actions, based on partnerships between players and movements of trick (AU)

Rheumatoid factor as predictor of response to abatacept, rituximab and tocilizumab in rheumatoid arthritis: Systematic review and meta-analysis.

OBJECTIVE: To identify if rheumatoid factor (RF) is predictor of response to rituximab (RTX), abatacept (ABT), and tocilizumab (TCZ) in rheumatoid arthritis (RA). METHODS: Systematic review and meta-analysis of clinical trials and observational studies based on a sensitive search. Meta-regression was used to explore causes of heterogeneity. Unpublished data of clinical trials provided by the authors were also included. RESULTS: The electronic search captured 3221 references and 422 meeting abstracts. By hand search, four additional articles were also identified. A total of 23 studies meet the purpose of the study and were included in the review. RF positivity at starting predicts better ACR20 [OR, 1.95 (1.24, 3.08)], ACR50 [OR, 5.38 (2.50, 11.60)] and EULAR response [OR, 3.52 (1.66, 7.45)] in 14 studies with RTX, and better ACR20 [OR, 1.51 (1.21, 1.90)] in 6 studies with TCZ. In 3 studies with ABT, no association was found between response and RF [OR 1.36 (0.97, 1.90)]. No asymmetries in the funnel plots or significant variables were found in the meta-regression. CONCLUSION: In RA, RF positivity predicts better response to RTX and TCZ but not to ABT.
