INTRODUCTION: Posttraumatic stress disorder (PTSD) develops in 1 out of 8 survivors of acute coronary syndrome (ACS) events, and these persons have a doubling of risk for recurrent ACS and mortality. Overcrowding in the emergency department during ACS evaluation has been associated with increased risk for PTSD, and depressed patients have been found to be particularly vulnerable. Little is known about the mechanisms by which overcrowding increases PTSD risk in depressed patients. Our aim was to evaluate one possible mechanism, patient perception of crowding and care, in depressed and nondepressed ED patients evaluated for ACS...

Anxiety has been proposed to influence psychophysiological reactivity in children and adolescents. However, the extant empirical literature has not always found physiological reactivity to be associated with anxiety in youth. Further, most investigations have not examined psychophysiological reactivity in real time over the course of acute stress. To test the impact of anxiety disorder status on autonomic arousal in youth, we compared youth with primary anxiety disorders (N = 24) to typically developing (TD) youth (N = 22) on heart rate (HR), heart rate variability (HRV), and respiratory sinus arrhythmia (RSA) during an acute stressor in which youth received error-related feedback...

BACKGROUND: Posttraumatic stress disorder (PTSD) is a stress disorder characterized by unwanted intrusive re-experiencing of an acutely distressing, often life-threatening, event, combined with symptoms of hyperarousal, avoidance, as well as negative thoughts and feelings. Evidence-based psychological interventions have been developed to treat these symptoms and reduce distress, the majority of which were designed to be delivered face-to-face with trained therapists. However, new developments in the use of technology to supplement and extend health care have led to the creation of e-Mental Health interventions...

BACKGROUND: Trauma patients suffer from acute stress disorder (ASD) and posttraumatic stress disorder (PTSD), but it is unknown how these disorders develop over time and when treatment is effective. Our aim was to systematically review (1) the course and predictors of ASD and PTSD after trauma and (2) which and when psychological treatments are effective. METHODS: Embase, Medline, Web of Science, Scopus, PsycInfo, Cinahl, Cochrane, PubMed, and Google Scholar were searched up to September 14, 2015...

Emerging evidence suggests that there is a window of opportunity within the early developmental period, when microbiota-based interventions could play a major role in modulating the gut-brain axis and, thereby, in preventing mood disorders. This study aims at evaluating the effects and mode of action of Bifidobacterium pseudocatenulatum CECT 7765 in a murine model of chronic stress induced by maternal separation (MS). C57Bl/6J male breast-fed pups were divided into four groups, which were subjected or not to MS and supplemented with placebo or B...

OBJECTIVE: Current practice guidelines do not recommend benzodiazepines for acute management of anxiety disorders in pediatric patients. However, in procedural settings, benzodiazepines are commonly used to relieve acute preprocedural stress. This meta-analysis examines the efficacy and tolerability of benzodiazepines as short-term anxiolytics in children. METHOD: PubMed was searched for randomized controlled trials assessing the efficacy of benzodiazepines as short-term anxiolytics in pediatric patients...

Mood congruent alterations in information processing such as an impaired memory bias for emotional information and impaired inhibitory functions are prominent features of a major depressive disorder (MDD). Furthermore, in MDD patients hypothalamic-pituitary-adrenal axis dysfunctions are frequently found. Impairing effects of stress or cortisol administration on memory retrieval as well as impairing stress effects on cognitive inhibition are well documented in healthy participants. In MDD patients, no effect of acute cortisol administration on memory retrieval was found...

OBJECTIVE: The potential influence of probiotic supplementation on cardiovascular health and stress responsivity remains largely unexplored. Some evidence suggests the possibility that probiotics may influence blood pressure. A separate body of research suggests that exaggerated cardiovascular reactions to acute psychological stress in the laboratory predict cardiovascular morbidity and mortality. The current investigation explored the effect of acute probiotic use on: 1) resting cardiovascular measures in healthy young adults and 2) cardiovascular and psychological reactions to an acute psychological stressor in the laboratory...

SIGNIFICANCE: Redox imbalance may lead to overproduction of reactive oxygen and nitrogen species (ROS/RNS) and subsequent oxidative tissue damage which is a critical event in the course of neurodegenerative diseases. It is still not fully elucidated, however, whether oxidative stress is the primary trigger or a consequence in process of neurodegeneration. Recent Advances: Increasing evidence suggests that oxidative stress is involved in the propagation of neuronal injury and consequent inflammatory response, which in concert promote development of pathological alterations characteristic of most common neurodegenerative diseases...

Jaimie L Gradus
Given the ubiquity of traumatic events, it is not surprising that posttraumatic stress disorder (PTSD) - a common diagnosis following one of these experiences - is characterized as conferring a large burden for individuals and society. Although there is recognition of the importance of PTSD diagnoses throughout psychiatry, the literature on other diagnoses one may receive following a stressful or traumatic event is scant. This review summarizes the literature on stress disorders (classified according to the International Classification of Diseases, 10th Edition [ICD-10]), including acute stress reaction, PTSD, adjustment disorder and unspecified stress reactions...

BACKGROUND AND PURPOSE: It has recently been suggested that 5-HT3 receptor blockade enhances selective serotonin reuptake inhibitor (SSRI) antidepressants efficacy and may reverse stress-induced deficits in rodents. EXPERIMENTAL APPROACH: To further explore this hypothesis, we used mice lacking the 5-HT3 receptor (Htr3a KO) and their wild-type (WT) controls to assess their response in behavioural paradigms relevant to anxiety and depression. Mice were studied under basal, antidepressant treatments and chronic social defeat stress (CSDS) conditions...

Toxic hepatitis induced by overdose of acetaminophen (APAP) is one of the major life-threatening problems, oxidative stress and inflammatory injury are the essential underlying mechanisms. 5-Azacytidine (5-AZA) is a ribonucleoside analogue which has been approved for the treatment of patients with acute myeloid leukemia and myelodyplastic syndrome, but recent studies also found that 5-AZA might have anti-oxidative and anti-inflammatory benefits in non-tumor disorders. In the present study, the potential effects of 5-AZA on APAP-induced toxic hepatitis were investigated in a mouse model in vivo...

Thrombotic thrombocytopenic purpura (TTP), a potentially fatal blood clot disorder, is primarily caused by severe deficiency of plasma ADAMTS13 activity resulting from acquired autoantibodies. Plasma exchange is the only effective initial therapy. However, the high mortality rate and the complications associated with plasma exchange therapy remain a major concern. To address unmet clinical needs, therapeutic efficacies of anfibatide, a snake venom-derived platelet glycoprotein Ib antagonist, in murine models of spontaneous thrombocytopenia and shigatoxin-induced TTP were determined...

Noribogaine is the main psychoactive metabolite of the hallucinogenic drug ibogaine, and is a particularly interesting compound potentially useful to treat dependence and various psychiatric disorders. Here, we report the effects of noribogaine on anxiety and locomotion in zebrafish (Danio rerio), a new promising model organism in neurobehavioral and psychopharmacological research. Adult zebrafish were subjected to the 5min novel tank test (NTT) following an acute, 20min drug immersion in 1, 5 and 10mg/L noribogaine...

Hyperventilation caused by physical and/or psychological stress may lead to significant respiratory alkalosis and an elevated systemic pH. The alkalotic pH may in turn suppress the normal renal release of phosphate into the urine, thereby interrupting the endogenous production of 1,25-dihydroxyvitamin D (calcitriol). This could cause a shortfall in its normal production, leading to a variety of adverse consequences. It might partially explain the pathogenesis of acute mountain sickness, a treatable disease characterized by severe hyperventilation secondary to the hypoxia of high altitude exposure...

Animal primary cell cultures are widely used in biomedical research to investigate cell metabolism, diseases and to devise novel treatments. Modern animal breeding techniques are developed to unify, control and reduce the amount of microorganisms that the animals are being exposed to. Furthermore, health monitoring and strict caging and handling protocols allow animals to be exposed only to a selected spectrum of microbes. We are starting to appreciate that nutrition can influence composition of gut microbiota that can impact hosting organism's physiology and can even result in development of pathological changes...

Many studies note that changes in oxidative balance are involved in the pathogenesis of major depressive disorder (MDD) and in the success of some antidepressants. Quetiapine exerts a therapeutic response and induces changes in physiological mechanisms that appear to underlie MDD. The objective of this study was to evaluate the antidepressant and antioxidant effects of quetiapine (20 mg /kg) in adult animals. Sixty minutes after an acute treatment or the last administration of chronic treatment (14 days) with quetiapine, animals were subjected to the forced swimming test (FST) to evaluate mobility parameters...
