Psychobiological responses at the beginning and the end of an academic year in teachers
2013
Evidence shows that work stress increases risk of cardiovascular disease. Emotional, cardiovascular and endocrine responses are affected by day-to-day experience. Perceived stress, negative mood, heart rate (HR) and blood pressure (BP) increase in working periods. Cortisol (C) response is not so clear, there being contradictory results. The main purpose is to study stress markers in two working days in teachers. Moreover, we evaluate the role of gender in stress markers in 49 school teachers. Perceived stress, mood, BP, HR, and C were measured at the beginning and at the end of an academic year. Results show that psychological and heart rate responses to a working day were different at the …
Modificación de la respuesta de estrés y desregulación del eje hipotalámico pituitario adrenal por un patrón de consumo binge drinking en adolescentes
2022
El consumo de alcohol se ha convertido en un problema de salud pública a nivel mundial. Un grupo especialmente afectado por dicho consumo es el de los adolescentes y los jóvenes adultos. En esta población predomina un patrón de consumo denominado Binge Drinking (BD). Su mantenimiento durante la adolescencia predice una respuesta de cortisol atípica al estrés en la edad adulta joven. Además, este tipo de consumo suele hacerse junto con otras sustancias psicoactivas, especialmente el tetrahidrocannabinol (THC). El estudio de las interacciones entre el consumo de alcohol y los sistemas biológicos de estrés se ha centrado en el eje hipotalámico-pituitario-adrenal (HPA) y en la principal hormona…
Neurobiology of performance anxiety:A new approach
2016
The aim of this study is to investigate the neurobiology of stress/emotionality, creating a multidisciplinary assessment model, which can help to provide psychological and physiological responses depending on the genetic background related to sport performances, social closeness and performance anxiety management in team sports. We enrolled 20 female volleyball players aged 13 ± 1 years old played in two different teams during a regional championship final. Saliva collection was carried out before and after the match. In order to evaluate the neuroendocrine effectors involved in stress and performance, we analyzed cortisol and progesterone levels through Elisa standard kit as well as HSP70 …
Neurosciences and attachment theory: A brief review
2017
The attachment theory was proposed and elaborated by John Bowlby. Over the last ten years the attachment theory has attracted considerable interest in the field of mental health as it emphasizes how relationships that are established in the earliest stages of development have an impact on man in an indefinable and lifelong manner.
Concurrent endurance and strength training : neuromuscular, cardiorespiratory and hormonal effects of the exercise order in previously untrained and …
2015
The aim of the present thesis was two-fold. First, to investigate physiological adaptations to concurrent endurance and strength training performed in the same session with different exercise orders (i.e. commencing training with endurance or strength, respectively; E+S vs. S+E) in previously untrained men (n=42) (study 1). Second, to examine physiological adaptations when strength training was always performed immediately after endurance running in the same session (E+S) compared to endurance training alone (E) in recreational endurance runners (n=30) (study 2). In study 1, training consisted of 2 - 3 weekly combined endurance cycling and mixed hypertrophic and maximal strength training se…
Autonomic, hormonal, and subjective responses to a modified version of the TSST: a pilot study
2021
El objetivo de esta investigación fue estudiar las respuestas hormonales, autonómicas y afectivas a una versión modificada del estresor TSST en una muestra de jóvenes universitarios compuesta de treinta y ocho sujetos (11 hombres y veintisiete mujeres, 11 en la fase lútea del ciclo menstrual, 16 mujeres en la fase folicular). La respuesta hormonal se evaluó con niveles de cortisol. La frecuencia cardíaca y la actividad electrodérmica se registraron durante toda la sesión experimental y la ansiedad rasgo y estado se evaluaron antes y después de la tarea. La fase de discurso provocó la frecuencia cardíaca más alta, la mayor frecuencia de respuestas inespecíficas y el mayor nivel de conductanc…
Vitamin D Deficiency in Cushing’s Disease: Before and After Its Supplementation
2022
Background: The primary objective of the study was to assess serum 25-hydroxyvitamin D [25(OH)D] values in patients with Cushing’s disease (CD), compared to controls. The secondary objective was to assess the response to a load of 150,000 U of cholecalciferol. Methods: In 50 patients with active CD and 48 controls, we evaluated the anthropometric and biochemical parameters, including insulin sensitivity estimation by the homeostatic model of insulin resistance, Matsuda Index and oral disposition index at baseline and in patients with CD also after 6 weeks of cholecalciferol supplementation. Results: At baseline, patients with CD showed a higher frequency of hypovitaminosis deficiency (p = 0…
Relación entre empatía y respuesta matutina de cortisol
2016
Con la finalidad de prevenir la conducta antisocial, el estudio de las bases biológicas de la empatía ha cobrado especial relevancia en los últimos años. Diversos estudios han resaltado la implicación del eje hipotálamo-hipófisis-adrenal (HHA) y el cortisol en la empatía, pero son escasos los que han estudiado la relación entre esta y la respuesta matutina de cortisol (CAR, por su nombre en inglés Cortisol Awakening Response) como indicador de la actividad basal del HHA. Este estudio analiza la asociación entre la empatía, tanto cognitiva como emocional, y la CAR en 39 hombres y 91 mujeres (47 fase folicular y 44 fase lútea del ciclo menstrual). La CAR se obtuvo a partir de muestras de sali…

Glucocorticoid excess and COVID-19 disease
2020
AbstractThe pandemic of coronavirus disease (COVID-19), a disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is causing high and rapid morbidity and mortality. Immune system response plays a crucial role in controlling and resolving the viral infection. Exogenous or endogenous glucocorticoid excess is characterized by increased susceptibility to infections, due to impairment of the innate and adaptive immune system. In addition, diabetes, hypertension, obesity and thromboembolism are conditions overrepresented in patients with hypercortisolism. Thus patients with chronic glucocorticoid (GC) excess may be at high risk of developing COVID-19 infection with a sever…
