Orexin system: Network multi-tasking
2018
Orexin system regulates sleep/wake states and its deficiency result in narcolepsy thus indicating the crucial role of orexins in maintaining wakefulness. There are two types of orexin peptides: the orexin-A (OXA or hypocretin 1) and orexin-B (OXB or hypocre- tin 2). The Majority of the central nervous system orexin peptides are synthesized in neurons located in the lateral and back hypotha- lamus and send projections throughout the brain regions Orexin neurons are “multi-tasking” hence regulating also energy homeosta- sis, reward systems and feeding behaviour through connection with hypothalamic nuclei and through responsiveness to leptine and glucose. It has recently been found a connectio…

Interactive Guidance Intervention to Address Sustained Social Withdrawal in Preterm Infants in Chile: Protocol for a Randomized Controlled Trial
2020
Background Preterm newborns can be exposed early to significant perinatal stress, and this stress can increase the risk of altered socioemotional development. Sustained social withdrawal in infants is an early indicator of emotional distress which is expressed by low reactivity to the environment, and if persistent, is frequently associated with altered psychological development. Infants born prematurely have a higher probability of developing sustained social withdrawal (adjusted odds ratio 1.84, 95% CI 1.04-3.26) than infants born full term, and there is a correlation between weight at birth and sustained social withdrawal at 12 months of age. Objective The aims of this study are to comp…
Emotional stress & decision-making: an emotional stressor significantly reduces loss aversion
2021
Stress influences loss aversion, the principle that losses loom larger than gains, although the nature of this relationship is unclear. Studies show that stress reduces loss aversion; however, stress response has been only studied by means of physiological measures, but the stressor emotional impact remained unclear. Since emotions can modify stress response and increase the activity of the loss aversion neural substrates, it could be expected that an emotional stressor may produce the opposite effect, i.e. loss aversion increase. 69 participants were divided into experimental and control group. The first one was exposed to emotional stress through a 5-minutes video, and control group viewe…
Takotsubo cardiomyopathy after a positive emotional stress
2013
Takotsubo cardiomyopathy, also known as transient left ventricular apical ballooning syndrome, is a cardiac syndrome mimicking an acute coronary syndrome and characterized by peculiar transient left ventricular wall motion in the absence of significant coronary lesions at coronary angiography. The pathogenic mechanisms linking emotional stress to Takotsubo cardiomyopathy still remain undefined. The onset of Takotsubo cardiomyopathy can be triggered by an acute, intense emotional stress. This is the first report reporting that not only negative stress but also positive stressful event may precede the syndrome.
