Perfil de estado de ánimo y autoeficacia percibida en tareas de salto con contramovimiento en atletas cubanos de élite

Introducción: El estado de ánimo y la autoeficacia presentan estrecha relación con el rendimiento deportivo. En atletismo, contar con un control exhaustivo del entrenamiento físico y mental supone asentar las bases del máximo rendimiento, siendo el salto vertical un excelente elemento de control. Sin embargo, su relación con los aspectos psicológicos durante los entrenamientos se ha divulgado poco en la literatura. Este artículo tiene como objetivo analizar la relación entre el perfil de estado de ánimo y la autoeficacia durante saltos verticales en deportistas juveniles de la preselección nacional cubana de atletismo. Método: Se evaluó el estado de ánimo y la autoeficacia antes de ejecutar un salto con contra movimiento (CMJ), presentándose el valor de 40 cm como elemento de máximo rendimiento en atletas de élite. Resultados: Se encontró correlación significativa entre el factor ansiedad del POMS y variables del CMJ. Además, se encontró correlación negativa entre la autoeficacia y la ansiedad, aunque no significativa (p > .05). Conclusiones: Los deportistas con un estado de ánimo de puntuación media de ansiedad, aunque no sobreelevada (puntaje 2 sobre 4) antes de la ejecución de saltos verticales, obtuvieron mejores resultados de CMJ, consiguiendo un mayor rendimiento tanto en la altura de salto, como en la velocidad, fuerza y potencia del salto. Sin embargo, no se hallaron correlaciones significativas entre la autoeficacia y el estado de ánimo, ni con variables de salto.

Introduction: Both mood and self-efficacy seem to be components closely related to the athlete's performance. In athletics, to have an exhaustive control of training from the physical and mental point of view is to lay the foundations for sporting success. Exercises such as the vertical jump are an excellent element of control of athletic performance. However, their relationship with psychological aspects during training has been little reported in the literature. Our objective was to analyze the relationship between the mood profile and self-efficacy during vertical jumps in youth athletes of the Cuban national preselection of athletics. Method: Mood and self-efficacy were evaluated before executing a countermovement jump (CMJ), presenting the 40-cm value as the element of maximum success in elite athletes. Results: A significant correlation was found between anxiogenic mood and vertical jump variables. In addition, a negative correlation was found between self-efficacy and anxiety, although not significant (p > .05). Conclusions: Athletes with a medium anxiety score mood although not overelevated (score 2 out of 4) before the execution of vertical jumps obtained better CMJ results, achieving higher performance in both jump height, speed, strength and power of the jump. However, no significant correlations were found between self-efficacy and mood, nor with the jumping variables.

Relationship between adverse events prevalence, patient safety culture and patient safety perception in a single sample of patients: a cross-sectional and correlational study.

OBJECTIVE: To assess the relationship between adverse events prevalence (AEP), patient safety culture (PSC) and patient safety perception (PSP). DESIGN: Cross-sectional, ex post facto comparative study on a single sample of patients. SETTING: Four medium-high-level hospitals were included in the study-two public and two private from Zulia State in Venezuela. PARTICIPANTS: 556 medical records and patients were studied for the prevalence and PSP study, and 397 of the healthcare providers involved in the care of these patients were surveyed for the PSC study, at two public and two private hospitals. OUTCOME MEASUREMENT: The primary outcome of this study was the association between AEP, PSC and PSP, and according to hospital funding type, private and public. RESULTS: An inverse association was observed between AEP and its severity and Patient Safety Culture Index (rho=-0.8, p=0.5) (95% CI 0.26-0.10) and Patient Safety Perception Index (rho=-0.6, p=0.18) (95% CI 0.10-0.28), which were protective factors for patient safety. No association was identified between PSC and PSP (rho=0.0001). No statistical differences were identified by hospital type (p=0.93) (95% CI 0.70-1.2). CONCLUSIONS: The analysis of the variable correlations studied (AEP, PSC and PSP) within the same sample offers an interesting and useful perspective. In this sample, although no correlation was observed between the three variables as an interacting set, some correlation patterns were observed between pairs of variables that could guide further studies.

Predictors of patient safety culture in hospitals in Venezuela: A cross-sectional study.

ABSTRACT: An organization's culture with regard to patient safety is important because it defines the beliefs and practices of the organization, and consequently its efficiency and productivity.Knowing the level of this and the factors that influence or not their dynamic represents a challenge, due to the degree of complexity and specificity of the elements involved.The aim of this study was to analyze predictors of patient safety culture in public and private hospitals and examining the factors that contribute to it, constructing a new and specific theoretical and methodological model.This study was carried out by reviewing medical records, detecting healthcare professionals directly involved in caring (N = 588), for patients in 2 public hospitals and 2 private hospitals in Venezuela (N = 566), conducting an "Analysis of Patient Safety Culture" questionnaire. The results were subsequently analyzed, derived 3 predictors factors and using a Patient Safety Culture Index (PSCI) for specific determination to evaluate patient safety culture level.The analysis showed that all hospitals had a "moderately unfavorable" PSCI (public = 52.96, private = 52.67, sig = 0.90). The PSCI was calculated by assessing the weight of the following factors in the index: occupational factors (factor loading = 32.03), communication factors (factor loading = 11.83), and organizational factors (factor loading = 9.10). Traumatology presented the lowest PSCI of all the care units, falling into the "unfavorable" category (36.48), and Laboratory the highest (70.02) (sig = 0.174), falling into the "moderately favorable" category. When analyzing professional groups, nurses had the highest PSCI, with a "moderately unfavorable" rating (PSCI = 61.1) and medical residents the lowest, falling into the "unfavorable" category (35.2). Adverse event reporting is determined by "management expectations and actions" (sig = 0.048) and "direct interaction with the patient" (sig = 0.049).The use of this theoretical and methodological approach in other contexts may provide a more objective system for identifying more specific needs and factors that influence in patient safety culture, and consequently, opportunities for improvement when constructing a patient safety culture in healthcare institutions. Efforts need to be made to improve safety culture in the hospitals studied, irrespective of whether they are public or private.

Phenolic composition and antioxidant properties of ex-situ conserved tomato (Solanum lycopersicum L.) germplasm.

Tomato (Solanum lycopersicum L.) local varieties represent a reservoir of genetic diversity for desirable quality traits. In this study, a representative collection of table tomato germplasm conserved ex-situ in the Portuguese Gene Bank was characterized for its polyphenols composition and antioxidant capacity. Phenolic acids, such as caffeic and p-coumaric acids bounded to a hexose and 5-O-caffeoylquinic acid, corresponded to 71-98% of the identified phenolic compounds; while the remaining fraction consisted of quercetin and kaempferol glycoside derivatives. Among the studied tomato accessions, it was possible to identify those that stand out for the analysed bioactive traits. These findings highlighted the interest of using Portuguese tomato germplasm in breeding programs or of reintroducing into cultivation these local varieties used for fresh consumption.

Manual de construcción antisísmica para estructuras menores

Manual de construcción antisísmica para estructuras menores: A raíz del sismo ocurrido en Popayán el 31 de marzo de 1983, la Asociación de Ingenieros del Valle creó un comité especial encargado de estudiar la forma de colaborar y de promover las acciones dirigidas a la reconstrucción de la ciudad. Dedido a la falta de información al alcance de muchas personas, de modo que ella fuera útil en el entendido del fenómeno sísmico y de las prácticas que se debían seguir para la reconstrucción de edificaciones, se decidió elaborar un documento que llenara ese vacío de información. Así nació este manual, con el cual se quiere llegar a una audiencia amplia prestando especial atención en ofrecer un lenguaje sencillo al alcance de todos aquellos que tengan una noción minima en el área de la construción. Con el fín de que sirva de introducción al tema de construcción y reconstrucción. En el primer capítulo del manual se presentan algunos comentarios sobre las materias que explican los fenómenos sísmicos. Los siguientes capítulos ofrecen recomendaciones y normas mínimas de construcción y reparación
