Peritraumatic dissociation, a term used to describe a complex array of reactions to trauma, including depersonalization, derealization, and emotional numbness, has been associated with posttraumatic stress disorder (PTSD) symptoms across a number of studies. Cognitive theory suggests that interpretations of traumatic events and reactions underlie the persistence of PTSD. The present study examined the associations among peritraumatic dissociation, posttraumatic cognitions, and PTSD symptoms in a group of trauma-exposed adults (N = 169)...

REVIEW
Annabel Broyd, Ryan P Balzan, Todd S Woodward, Paul Allen
This paper examines the evidence that delusions can be explained within the framework of a neurocognitive model of how the brain assesses certainty. Here, 'certainty' refers to both low-level interpretations of one's environment and high-level (conscious) appraisals of one's beliefs and experiences. A model is proposed explaining how the brain systems responsible for assigning certainty might dysfunction, contributing to the cause and maintenance of delusional beliefs. It is suggested that delusions arise through a combination of perturbed striatal dopamine and aberrant salience as well as cognitive biases such as the tendency to jump to conclusions (JTC) and hypersalience of evidence-hypothesis matches...

Importance: Existing patient-reported outcome measures of tinnitus assess the severity and disability retrospectively, which may result in adequate reliability, but cannot capture the fluctuating and individualized nature of tinnitus. Experience sampling may provide an alternative. Objective: To use an ecological momentary assessment (EMA) to measure tinnitus disability and associated constructs. Design, Setting, and Participants: Forty adults with tinnitus provided self-report of their tinnitus bother using 5 questions measured by EMA, as well as standard retrospective outcome measures...

OBJECTIVE: This study examined the effects of disaster-related prenatal maternal stress on infant temperament and whether the sex of the infant or the timing of the stressor in pregnancy would moderate the effects. METHODS: Mothers' objective experiences of a sudden-onset flood in Queensland, Australia, their subjective emotional reactions, and cognitive appraisal of the event were assessed. At 6 months postpartum, 121 mothers reported their infant's temperament on the 5 dimensions of the Short Temperament Scale for Infants...

In middle age, some people may become mentally or emotionally unstable. Additionally, in Japan, mood disorders, such as depressive symptoms, occur mostly among middle-aged women (i.e., aged 40-49 years). However, few studies have examined stressors related to mental health (a state of well-being in which every individual realizes his or her own potential, can cope with the normal stresses of life, can work productively and fruitfully, and is able to make a contribution to her or his community). In the present research, we developed a stressor scale for middle-aged women (SSMW) and examined stressors correlated with middle-aged women's mental health...

OBJECTIVE: Acquired brain injury (ABI) is associated with many physical and psychiatric conditions. Oftentimes, the individual's family members are responsible for providing long-term care, leaving caregivers vulnerable to negative effects of caregiving including stress, depression, and decreased quality of life. Attribution theory suggests that caregivers may blame the individual with the ABI for their injury as a way to understand their own circumstances. The objective of this study was to investigate caregiver coping strategies as possible mediators between caregiver family member blame and caregiver psychosocial outcomes among caregivers of individuals with ABI...

INTRODUCTION: Recently, the incidence of obesity, especially extreme obesity, has significantly increased. It is connected with inappropriate lifestyle, including a high calorie diet, psychological and genetic factors, some medications, diseases or infectious factors. Nowadays, the consumption of food is not only to satisfy a physiological need, but also fulfils psychological needs. The most effective method of morbid obesity treatment is metabolic surgery. Moreover, food is considered to be a reward and method of coping with stress...

A fundamental adaptive mechanism of auditory function is inhibitory gating (IG), which refers to the attenuation of neural responses to repeated sound stimuli. IG is drastically impaired in individuals with emotional and cognitive impairments (i.e., posttraumatic stress disorder). The objective of this study was to test whether chronic stress impairs the IG of the auditory cortex (AC). We used the standard two-tone stimulus paradigm and examined the parametric qualities of IG in the AC of rats by recording the electrophysiological signals of a single-unit and local field potential (LFP) simultaneously...

Fear of predation is a universal motivator. Because predators hunt using stealth and surprise, there is a widespread ability among prey to assess risk from chemical information - scents - in their environment. Consequently, scents often act as particularly strong modulators of memory and emotions. Recent advances in ecological research and analytical technology are leading to novel ways to use this chemical information to create effective attractants, repellents and anti-anxiolytic compounds for wildlife managers, conservation biologists and health practitioners...

The present study aimed to investigate the effectiveness of a psychoeducational intervention on caregivers of patients assisted by the Center for Psychosocial Health Care (CPHC) focusing on the patient's psychopathology. This was a randomized clinical trial with 130 caregivers with higher mean burden scores assessed using the Zarit Burden Interview Scale (ZBI) (66 caregivers in the intervention group and 64 in the control group). The intervention included six home visits of psychoeducational interventions according to each mental disorder identified in the CPHC records...

As many as one billion children experience violence every year, and household- and community-level poverty are among the risk factors for child protection violations. Social safety nets (SSNs) are a main policy tool to address poverty and vulnerability, and there is substantial evidence demonstrating positive effects on children's health and human capital. This paper reviews evidence and develops a framework to understand linkages between non-contributory SSNs and the experience of childhood emotional, physical and sexual violence in low- and middle-income countries...

Diagnosis and treatment of childhood acute lymphoblastic leukemia (ALL) can be a highly stressful time for the entire family. While completion of treatment may bring relief to some families, it may also bring about additional anxieties and fear. The primary objective of this article is to present an analysis of the experiences, emotional states, and support needs of parents of pediatric cancer patients 2 months after treatment completion for ALL. Using a qualitative interpretive description approach, transcripts from interviews with 17 parents from the leukemia/lymphoma program of a large urban pediatric cancer center were analyzed using N-Vivo 10 data analysis software...

BACKGROUND: The stress sensitization theory hypothesizes that individuals exposed to childhood adversity will be more vulnerable to mental disorders from proximal stressors. We aimed to test this theory with respect to risk of 30-day major depressive episode (MDE) and generalized anxiety disorder (GAD) among new US Army soldiers. METHODS: The sample consisted of 30 436 new soldier recruits in the Army Study to Assess Risk and Resilience (Army STARRS). Generalized linear models were constructed, and additive interactions between childhood maltreatment profiles and level of 12-month stressful experiences on the risk of 30-day MDE and GAD were analyzed...

Translationally controlled tumor protein (TCTP) is a cytosolic protein with microtubule stabilization and calcium-binding activities. TCTP is expressed in most organs including the nervous system. However, detailed distribution and functional significance of TCTP in the brain remain unexplored. In this study, we investigated the global and subcellular distributions of TCTP in the mouse brain. Immunohistochemical analyses with anti-TCTP revealed that TCTP was widely distributed in almost all regions of the brain including the cerebral cortex, thalamus, hypothalamus, hippocampus, and amygdala, wherein it was localized in axon tracts and axon terminals...

Major depressive disorder (MDD) is a condition which has often been associated with chronic stress. The sympathetic nervous system is continuously activated without the normal counteraction of the parasympathetic nervous system under the influence of chronic stress. As a result, epinephrine and norepinephrine levels are increased, and acetylcholine levels are decreased, which in turn can increase the levels of pro-inflammatory cytokines. Peripheral inflammatory responses can access the brain, with neuroinflammation contributing to the increase in neurotoxic kynurenine pathway metabolites such as 3-hydroxykynurenine, 3-hydroxyanthranilic acid and quinolinic acid, and decrease in neuroprotective metabolites such as kynurenic acid...

The N-methyl-D-aspartate receptor antagonist ketamine has rapid onset activity in treatment-resistant depression, post-traumatic stress disorder and obsessive compulsive disorder. Due to similarities in brain network activity in depression and anxiety disorders, we hypothesized that ketamine might also be active in other refractory anxiety disorders. We evaluated the efficacy and safety of ketamine in 12 patients with refractory generalized anxiety disorder and/or social anxiety disorder who were not currently depressed, using an ascending single dose study design (0...

To examine the underlying substructure of DSM-5 PTSD in an adolescent sample, this study used a confirmatory factor analysis alternative model approach to assess 813 adolescents two and a half years after the Ya'an earthquake. Participants completed the PTSD Checklist for DSM-5, the Center for Epidemiologic Studies Depression Scale for Children, and the Screen for Child Anxiety Related Emotional Disorders. The results found that the seven-factor hybrid PTSD model entailing intrusion, avoidance, negative affect, anhedonia, externalizing behaviors, anxious arousal, and dysphoric arousal had significantly better fit indices than other alternative models...

A severe mental illness like Post Traumatic Stress Disorder (PTSD) is known to have psychosocial consequences that can lead to a decreased quality of life. Research in Animal-Assisted Therapy (AAT) has revealed that the presence of a dog can have a positive effect on health, e.g., increase quality of life and lessen depression and anxiety. However, canine companionship is not a catch-all solution. Previous research has revealed methodological limitations that prohibit any clear conclusions, as well as a sparsity of critical reflection in anecdotal reports and case studies, which means that more research is needed to contextualize the findings...
