ABSTRACT

Spanish medical graduates who apply for a medical specialty training position (MIR) must take an examination that will shape their future personal and professional lives. Preparation for the test represents an important stressor that persists for several months. The aim of this study was to elucidate the stress pattern of this group and evaluate possible changes in the circadian rhythm of cortisol release in medical graduates preparing for this test. A repeated-measures longitudinal study was performed, measuring the salivary cortisol concentrations in 36 medical graduates (13 males and 23 females; mean age of 24.2 years) on five sampling days. Five cortisol samples were collected from 07:00 to 21:00 h in order to monitor changes in the circadian rhythm. On all sampling days (except on the day of the official examination), anxiety and psychological stress were evaluated with the Spanish versions of the State-Trait Anxiety Inventory (STAI) and the Perceived Stress Scale (PSS). During the study period, participants showed higher levels of anxiety than the Spanish reference population as well as a progressive increase in self-perceived stress. A significant increase in salivary cortisol concentration was observed in both chronic (study and examination preparation) and acute (examinations) situations. Our results suggest that the cortisol awakening response (CAR) may be a good indicator of anticipatory stress but is unaffected by long-term examination preparation. Comparison of results between the official examination day and the mock examination days yielded evidence that learning may modulate the behavior of the hypothalamic-pituitary-adrenal axis.

ABSTRACT

A menudo, el diagnóstico de demencia ha sido facilitado a través de pruebas psicométricas. El deterioro de las habilidades en estos pacientes, puede ser evaluado desde tests de screening a baterías neuropsicológicas. Actualmente, existen muchas investigaciones que han estudiado la necesidad de estos instrumentos en el diagnóstico de demencia. El siguiente artículo es un estudio sobre los tests que evalúan el deterioro cognitivo y el declive funcional en actividades de la vida diaria en pacientes con posible demencia. (AU)

ABSTRACT

El diagnóstico de demencia considera una pérdida de habilidades intelectuales que interfiere con la función social y ocupacional. Esto es muy importante en términos humanos. asimismo es díficil de determinar la proporción del coste económico gastado en el cuidado de estos pacientes. Actualmente, muchos estudios han investigado la prevalencia y la incidencia de la demenmcia en la población anciana, posiblemente debido al incremento dramático en los países de mayor desarrollo económico (AU)

ABSTRACT

El propósito de esta investigación fue estudiar el poder discriminante de las pruebas neuropsicológicas de la "Batería Abreviada Grganada de Evaluación Neuropsicológica" (BAGEN). Los resultados sugieren que la prueba de memoria y la prueba de cálculo son las más importantes en el diagnóstico de la demencia (AU)

ABSTRACT

BAGEN fue diseñada para evaluar demencias en pacientes con bajo nivel educativo. Evalúa orientación, lenguaje, memoria, praxias y atención. El principal objetivo de este estudio fue determinar los ítems con mayor poder discriminante entre demencia y otros trastornos cognitivos. Dos grupos, formaron un total de 144 sujetos. Todos los sujetos incluidos en el informe habían completado todas las pruebas neuropsicológicas. El diagnóstico de demencia estuvo basado en un examen clínico. El resultado de esta investigación sugiere que algunos ítems pueden ser eliminados de la batería (AU)

ABSTRACT

INTRODUCTION: Natural venoms produced by different species of animals are very useful to distinguish between the different types and subtypes of ionic channels and neurotransmitters receptors involved in the information processing in the nervous system. DEVELOPMENT: Natural venoms permit distinction between the different types and subtypes of Na+, K+ and Ca2+ channels. These differences are based on their structure, physical and chemical characteristics and function with regard to ionic transport and the neurotransmitters release. CONCLUSIONS: The use of different molecular biology techniques makes it possible to develop new synthetic toxins, by means of which new perspectives appear for the study and treatment of different neurological disease.

ABSTRACT

Intravenous brain angioscintigraphy in combination with immediate static scan are very useful as a complement to the clinical and electroencephalographic data in diagnosis of brain death. Confusion in the differentiation of extracerebral from intracerebral flow on the dynamic radionuclide angiogram can be accomplished by identifying presence or absence of uptake in cerebral sinuses. Authors consider that the radionuclide study should be carried out in posterior view. Exploration is safe, quick to perform and easy to interpret and it enables to distinguish brain death from comas due to drug intoxication.
