RESUMO
El objetivo de este estudio fue analizar la secuencia de los dos últimos golpeos del punto en pádel, y clasificarlos a través de árbol decisional multivariante. Se analizaron un total de 2110 acciones de juego, siendo las variables analizadas: golpeo, zona de la pista, eficacia, dirección, resultado y lado de juego. Los partidos fueron analizados mediante observación sistemática. Los resultados mostraron que mantener posiciones cercanas a la red aumenta las probabilidades de victoria, observándose que las secuencias de finalización más frecuentes son las de fondo-volea y globo-remate. Las parejas ganadoras realizan mayor número de puntos ganadores en la red y menos errores en el fondo de la pista. Además, utilizar trayectorias cruzadas en el penúltimo golpe aumentará las posibilidades de un error posterior de los rivales. Estos datos tienen aplicación práctica en el entrenamiento perceptivo y decisional del jugador de pádel, y la aplicación de feedbacks por parte del entrenador. (AU)
The main objective was to analyze the sequence of the last two shots of the point in padel and to make a classification through the multivariate decision tree approach. A total of 2110 game actions were analyzed. The variables analyzed were: shot, court zone, efficiency, direction, match outcome and side court. Matches were analyzed through systematic observation. The results determined that maintain net positions during the last two shots would increase the probabilities of victory, observing that the most frequent sequence of the last two shots were groundstroke-volley and lob-smash. In addition, winners make the highest number of winning points on the net and the least number of errors at the baseline. On the other hand, the use of cross-court shots will increase the chances of a opponents error. These data have an important practical application in the perceptive and decisional training and the feedback application by the coach. (AU)

Many studies have shown that the prevalence of malnutrition in hospitals is high. Our aim in this study is to ensure the systematic use of a preoperative nutritional evaluation (PNE) that ensures simplicity and usefulness in hospital nursing assistance. A total of 96 patients were studied, of whom 31 were diagnosed as having neoplasia and 65 non-neoplasia. For the purpose of this evaluation, the Chang method was used, completed with the application of retarded immunity skin tests. Malnutrition was observed in 71% por patients with neoplasia, mainly corresponding to slight Marasmo grade. In non-neoplasic patients malnutrition was 46%, also corresponding to slight Marasmo grade. In patients with neoplasia, anergy was evident in 54.9% of cases, and accounted for 23.1% in non-neoplasic patients. The development of anergy in both types of patients was significantly greater (p less than 0.05) in patients over 65 years of age. The inclusion of a PNE should form part of the nursing protocols, being used systematically in the study and control of surgical patients.
