BACKGROUND: The operating theatre, anaesthesia induction and separation from parents create fear and anxiety in children. Anxiety leads to adverse behavioral changes appearing and sometimes persisting during the postoperative period. Our aim was to compare the effects of midazolam (0.3 mg kg(-)(1): MDZ) for premedication with age-appropriate tablet game apps (TAB) on children anxiety during and after ambulatory surgery. METHODS: A randomized controlled trial was conducted from May 16th, 2013 to March 25th, 2014 at the Children Hospital of Lyon...

Numerous researches supported that microbiota can influence behavior and modulate cognitive function through "microbiota-gut-brain" axis. Our previous study has demonstrated that ZiBuPiYin recipe (ZBPYR) possesses excellent pharmacological effects against diabetes-associated cognitive decline. To elucidate the role of ZBPYR in regulating the balance of gut microbiota to improve psychological-stress-induced diabetes-associated cognitive decline (PSDACD), we compared blood glucose, behavioral and cognitive functions and diversity of the bacterial community among experimental groups...

Respiratory problems and posttraumatic stress disorder (PTSD) are the signature health consequences associated with the September 11, 2001 (9/11), World Trade Center disaster and frequently co-occur. The reasons for this comorbidity, however, remain unknown. Anxiety sensitivity is a transdiagnostic trait that is associated with both PTSD and respiratory symptoms. The present study explored whether anxiety sensitivity could explain the experience of respiratory symptoms in trauma-exposed smokers with PTSD symptoms...

Traditional models of posttraumatic stress disorder (PTSD) claim that the high emotional intensity of traumatic events leads to deficits in the voluntary access of traumatic memories. This may result in disorganized narratives, with a high sense of emotional and sensory reliving. Alternatively, the basic mechanisms view suggests that high arousal leads to more available involuntary and voluntary memories. Traumatic narratives would not be impaired; indeed, they would be immersive and rich in detail. To test this perspective, this study compared the trauma narratives of 50 battered women (trauma-exposed group) with narratives about positive experiences and narratives of 50 nonexposed women (controls), and analyzed the relationship between trauma narrative aspects and the severity of PTSD...

Excess glucocorticoid transferred from stressed mother to the embryo affects developing vertebrate offspring, but the underlying programming events are unclear. In this study, we tested the hypothesis that increased zygotic glucocorticoid deposition, mimicking a maternal stress scenario, modifies early brain development and larval behaviour in zebrafish (Danio rerio). Cortisol was microinjected into the yolk at one cell-stage, to mimic maternal transfer, and the larvae [96 hours post-fertilization (hpf)] displayed increased activity in light and a reduction in thigmotaxis, a behavioural model for anxiety, suggesting an increased propensity for boldness...

The molecular processes that establish fear memory are complex and involve a combination of genetic and epigenetic influences. Dysregulation of these processes can manifest in humans as a range of fear-related anxiety disorders like post-traumatic stress disorders (PTSD). In the present study, immunohistochemistry for acetyl H3, H4, c-fos, CBP (CREB-binding protein) in the infralimbic prefrontal cortex (IL-PFC) and prelimbic prefrontal cortex (PL-PFC) of mPFC (medial prefrontal cortex) and basal amygdala (BA), lateral amygdala (LA), centrolateral amygdala (CeL), centromedial amygdala (CeM) of the amygdala was performed to link region-specific histone acetylation to fear and extinction learning...

OBJECTIVE: Subthreshold posttraumatic stress disorder (SPTSD), a condition that meets the full symptomatic criteria of posttraumatic stress disorder (PTSD) without subjective functional impairment, has yet to be fully investigated. In this study, we aimed to determine the prevalence and characteristics of SPTSD. METHODS: The web-based survey including psychiatric diagnosis and experience of human error was conducted in actively working train drivers in South Korea...

A fast and validated supercritical fluid chromatography method for the quantitative determination of major lactones in Piper methysticum, a plant used against nervous anxiety, stress, and restlessness, was developed. The baseline separation of dihydrokavain, demethoxyyangonin, kavain, yangonin, dihydromethysticin, and methysticin was possible in less than 4 min on an Aquity UPC(2) BEH 1.7 µm column, in combination with a mobile phase comprising CO2 and methanol with diethylamine. The column temperature had a great impact on the results because only at 70 °C could kavain and yangonin be fully resolved...

BACKGROUND: Existing literature suggests that endocrine measures, including the steroid hormones of cortisol and Dehydroepiandrosterone (DHEA), as well as the DHEA to cortisol ratio in the human hair can be used as promising biomarkers of chronic stress among humans. However, data are limited regarding the validity of these measures as biomarkers of chronic stress among people living with HIV (PLWH), whose endocrine system or hypothalamic pituitary adrenal (HPA) axis may be affected by HIV infection and/or antiretroviral therapy (ART) medications...

REVIEW
James W Maniscalco, Linda Rinaman
Periods of caloric deficit substantially attenuate many centrally mediated responses to acute stress, including neural drive to the hypothalamic-pituitary-adrenal (HPA) axis, anxiety-like behavior, and stress-induced suppression of food intake (i.e., stress hypophagia). It is posited that this stress response plasticity supports food foraging and promotes intake during periods of negative energy balance, even in the face of other internal or external threats, thereby increasing the likelihood that energy stores are repleted...

Adolescence is a time period in development when the brain undergoes substantial remodeling in response to the environment. To determine if a stressful experience during adolescence affects adult behavior, we exposed adolescent male and female C57BL/6J mice to chronic unpredictable stress (CUS) for 12 days starting at post-natal day 28 (PND28). We also exposed adult male and female mice to CUS for 12 days beginning at PND70 to determine if adolescence is a sensitive time period when stress can have long-lasting effects on behavior...

Negative emotion (NE) is one of the most widely examined risk factors for suicide ideation (SI) and suicide attempt (SA). However, little is known about the possibly different mechanisms underlying the pathways from NE to these two different suicide phenomena. Nonsuicidal self-injury (NSSI) is related to both negative emotions and suicidality. Thus, the present study aimed to test the differential roles of NSSI in the pathways from NE (specified by depression, anxiety, and stress) to SI and from NE to SA. This study hypothesized that NSSI served as a mediator in the relationship from NE to SA, but not in the relationship from NE to SI...

Aberrant glucocorticoid secretion is implicated in the pathophysiology of stress-related disorders (i.e., depression, anxiety). Glucocorticoids exert biological effects via mineralocorticoid (MR) and glucocorticoid (GR) receptors. Previous data from our laboratory indicate that GR antagonism/modulation (i.e., mifepristone, CORT 108297) regulate endocrine, behavioral, and central stress responses. Because of the dynamic interplay between MR and GR on HPA axis regulation and emotionality, compounds targeting both receptors are of interest for stress-related pathology...

PURPOSE: Pain in patients with endometriosis is considered a significant source of stress but does not always correlate with severity of the condition. We have demonstrated that stress can worsen endometriosis in an animal model. Here, we tested the impact of a psychological stress protocol on pain thresholds and pain receptors. METHODS: Endometriosis was induced in female rats by suturing uterine horn tissue next to the intestinal mesentery. Sham rats had sutures only...

Curiosity, the tendency to engage in novel and challenging opportunities, may be an important source of resilience for those at risk for suicide. We hypothesized that curiosity would have a buffering effect against risk conferred by multiple sources of distress, whereby curiosity would be associated with reduced suicidal ideation and increased coping efficacy. As part of a larger intervention trial designed to improve coping skills and reduce suicidal ideation, 117 military veterans with suicidal ideation completed measures of curiosity and distress (perceived stress, depression, anxiety, and sleep disturbances) at baseline, and completed measures of suicidal ideation and coping efficacy (to stop negative thoughts, to enlist support from friends and family) at baseline and 3-, 6-, and 12-week follow up...

Treatments for chronic pain are inadequate, and new options are needed. Nonpharmaceutical approaches are especially attractive with many potential advantages including safety. Light therapy has been suggested to be beneficial in certain medical conditions such as depression, but this approach remains to be explored for modulation of pain. We investigated the effects of light-emitting diodes (LEDs), in the visible spectrum, on acute sensory thresholds in naive rats as well as in experimental neuropathic pain...

Stress during pregnancy can induce various psychological disorders in women. However, the association linking psychological stress during pregnancy with abnormal behaviours in females remains largely unknown. We employed a novel psychological stress model by introducing pregnant mice to witness the defeat process of their mated partner (WDPMP) and examined the effects of WDPMP on depression-/anxiety-like behaviours and on the expression of brain-derived neurotrophic factor (BDNF) and miR-206-3p in the hippocampus, medial prefrontal cortex (mPFC) and amygdala...
