RESUMEN
BACKGROUND: To study the relationship between psychological factors such as the anxiety trait and the possibility of suffering a sports injury in soccer players. SUBJECTS AND METHOD: In this study we analysed a sample of 149 males soccer players using a classic statistical analysis of case-control design studies, the relationship between the "sports injury" effect and the theoretical risk indicator of "the anxiety trait" measured using the Sixteen Personality Factors (16PF). RESULTS: It was found that there is indeed a relationship (odds ratio [OR] = 3.4; CI 95%; 1.03-11.4) between high levels in the anxiety trait and a proneness to suffering injuries, however, apart from confirming this idea which has been put forward by several authors, our results suggested that a very high or very low anxiety trait score favours the possibility of suffering an injury (OR = 3.2; CI 95%: 1.4-7.5). CONCLUSIONS: In soccer players to minimize the risk of sports injuries an optimum anxiety trait score is important as extreme scores, whether these are high or low, are associated with a greater risk of suffering injuries. Thus, if this individual characteristic is known, then it is possible to identify those persons who are predisposed to suffering sport injuries.

A study of the main prognostic factors and of the overall survival rate of gastric cancer (GC) is presented. It covered 895 cases diagnosed histopathologically in the province of Zaragoza (Spain) over a ten-year period (1980-1989). The analysis of the survival rate was carried out according to the Kaplan-Meier method and the Mantel-Haenszel test. The average overall survival rate of the sample was 6.5 months and the five-year survival rate was 16.5%. Lauren's intestinal histological type is associated with a better prognosis (a five-year survival rate of 25%) than the diffuse type (15%). The survival rate with regard to gastric wall invasion ranges from 78% for T1 tumors to 8% for T4 tumors (p < 0.0001). There are significant differences in survival rate between the TNM classification stages, ranging from a five-year survival rate of 77% for Stage I to 0% for Stage IV.
