[Takotsubo cardiomyopathy: a consensus document].
2008
Takotsubo cardiomyopathy is a syndrome characterized by acute regional systolic dysfunction of the left ventricle, frequently related to psycho-physical acute stress, and usually reversible. This rare syndrome involves more often the female sex with the highest frequency of occurrence between the seventh and eighth decade of life. Etiology has not been clarified yet and several hypotheses have been postulated: multiple epicardial coronary artery damage, abnormal coronary microcirculation, catecholamine-mediated cardiac toxicity, and neurogenic stunning. Clinical presentation is not easy to distinguish from an acute coronary syndrome: chest pain at rest or dyspnea, new-onset electrocardiogra…
Alexithymia as a Predictor of Arousal and Affect Dysregulations when Batterers with Attention Deficit Hyperactivity Disorder Cope with Acute Stress
2020
Empirical research has stated that Attention Deficit Hyperactivity Disorder (ADHD) might underlie intimate partner violence against women (IPVAW) perpetration. Even though there is a clear relationship between these two variables, it is still unknown how ADHD facilitates violence proneness. In this regard, psychophysiological variables such as skin conductance levels (SCL) might offer information about emotional regulation when individuals cope with stress. Furthermore, alexithymia traits might be a strong candidate in explaining the above-mentioned emotional dysregulations. Hence, we compared the SCL response to acute cognitive stress in IPVAW perpetrators with and without ADHD symptoms to…
Ansiedad social subclínica en adultos jóvenes sanos: cortisol y ansiedad subjetiva en respuesta a estrés agudo
2021
No existe consenso sobre el patrón de liberación de cortisol y su relación con la ansiedad subjetiva en situaciones de estrés en población con ansiedad social. Nuestro objetivo fue determinar la respuesta de cortisol y ansiedad subjetiva en individuos con ansiedad social sometidos a un estresor psicosocial agudo. 26 universitarios (58.6% hombres), edad media = 21.62 ± 0.43, fueron expuestos a la versión estrés o control del Maastricht Acute Stress Test. El cortisol salival y la ansiedad subjetiva fueron medidos antes, durante y post-estrés. Los participantes mostraron un incremento en los niveles de cortisol durante las fases de estrés y post-estrés, con una respuesta significativamente may…
AGE DIFFERENCES IN THE ACUTE STRESS EFFECTS ON DECLARATIVE MEMORY PERFORMANCE
2021
"In the last decades, there has been a growing interest in knowing the effects of acute stress on memory performance, particularly declarative memory. Research on this topic suggests that age is a crucial individual factor to consider in the stress-memory link. However, most of the evidence has been obtained from studies conducted in young people and, surprisingly, studies in older people are scarce. Thus, our aim was to investigate the age differences in the acute stress effects on declarative memory performance. To do this, we directly compared the effects of a psychosocial acute stressor (i.e. Trier Social Stress Test) on learning, consolidation and memory retrieval performance in two ag…
Lindane-induced changes in carbohydrate metabolism in Anguilla anguilla
1992
Abstract 1. Anguilla anguilla (L.) was exposed to a sublethal concentration of 0.167 ppm (0.25 of the 96-hr lc 50 ) of lindane for 6, 12, 24, 48, 72 and 96 hr. 2. Changes in glycogen, glucose, pyruvate and lactate contents of liver and muscle after lindane exposure, were studied. 3. Muscle and liver glycogen levels decreased significantly during the exposure time. Muscle glucose values increased but on the other hand we found a decrease in those of liver. 4. Muscle and liver pyruvate content increased as did lactate levels in both tissues. 5. The observed effects of lindane on carbohydrate metabolism in fish are discussed in relation to acute stress syndrome.
Exercise and Recovery Responses of Lymphokines to Heavy Resistance Exercise
2000
To examine the effect of dynamic resistance exercise on the response patterns of lymphokines, 10 strength-trained men (21.7 +- 0.6 y) performed 2 resistance exercise protocols, high force (HF) and high power (HP), of equal total work (HF 5 33.0 +- 2.5 kJ; HP 5 33.3 +- 2.7 kJ) in a randomized order separated by 1 week. Resting blood samples were obtained preexercise and 0 (R-0), 15 (R-15), and 240 (R-240) minutes postexercise. Plasma lactate significantly (p < 0.05) increased from baseline for both protocols; however, concentrations were higher in response to the HF protocol. Plasma interleukin- 2 (IL-2) concentrations were significantly decreased from baseline at R-15 following the HF proto…
Stress Hyperglycemia as Predictive Factor of Recurrence in Children with Febrile Seizures
2020
Stress hyperglycemia and hyperlactatemia are commonly referred to as markers of stress severity and poor outcome in children with severe acute illness or febrile seizures. Our prospective study aimed to explore the risk factors for stress hyperglycemia and the predictive value of stress hyperglycemia for febrile seizure recurrence. We evaluated as risk factors for blood glucose level, serum lactate, acid&ndash
