BACKGROUND: Oncology nurses have a higher risk and rate of compassion fatigue (CF) compared to professionals in other specialties. CF exhibits tangible negative outcomes, affecting nurses' health and professional practice.
. OBJECTIVES: Early-career oncology nurses' unique CF experiences lack thorough scientific exploration. This secondary analysis seeks to qualitatively augment this paucity and illuminate targeted interventions.
. METHODS: Open-ended interviews were conducted with five early-career inpatient oncology nurses...

The digital transformation of hospitals in Australia is occurring rapidly in order to facilitate innovation and improve efficiency. Rapid transformation can cause temporary disruption of hospital workflows and staff as processes are adapted to the new digital workflows. The aim of this paper is to outline various types of digital disruption and some strategies for effective management. A large tertiary university hospital recently underwent a rapid, successful roll-out of an integrated electronic medical record (EMR)...

BACKGROUND: Exposure to violence in the mental health sector both affects employees and has implications for the quality of care provided. OBJECTIVE: This phenomenological study aims to describe and understand the ways in which acts of aggression from a patient might affect workers in a psychiatric institute, their relationships with the patients and the services offered. METHODS: Two semi-structured interviews were conducted with each of the 15 participants from various professions within a psychiatric hospital...

PTSD elicits hypervigilance to trauma-related stimuli. Our novel research examined event-related potentials from Blood, Anatomy, and Morbid content derived from the Rorschach's Traumatic Content Index (TCI). Participants included: 16 with PTSD, 24 trauma-exposed without PTSD (Non-PTSD), and 16 non-traumatized Controls. P3 oddball paradigms were used with TCI-derived Distractors and neutral Targets/Standards. We predicted larger P3 amplitudes in the context of TCI-related Distractors among trauma-exposed participants...

OBJECTIVE: We investigated if certainty and uncertainty of impending aversive visceral sensation differently modulate regional brain activity, both during anticipation and visceral sensation in irritable bowel syndrome (IBS) patients compared with healthy controls. METHODS: Twenty-six IBS patients (14 women) and 29 healthy controls (15 women) were enrolled in an fMRI study. Participants received rectal distention at an individually titrated severe discomfort level that was preceded by visual cues to induce certain (100% chance of distention), uncertain (50% chance), and safe (0% chance) anticipation...

The standard clinical technique for using repetitive transcranial magnetic stimulation (rTMS) for major depressive disorder (MDD) is associated with limited efficacy to date. Such limited efficacy may be due to reliance on scalp-based targeting rather than state-of-the-science methods which incorporate fMRI-guided neuronavigation based on a specific model of neurocircuit dysfunction. In this review, we examine such a specific model drawn from regulatory focus theory, which postulates two brain/behavior systems, the promotion and prevention systems, underlying goal pursuit...

Attentional bias towards threat can be demonstrated by enhanced processing of threat-related targets and/or greater interference when threat-related distractors are present. These effects are argued to reflect processing within the orienting and executive control networks of the brain respectively. This study investigated behavioural (RT) and electrophysiological correlates of early selective attention and top-down attentional control among females with high (n = 16) or low (n = 16) spider fear (Mean age = 22 years)...

In Part 1 of this paper, we discussed emerging evidence suggesting that a general psychopathology or 'p' factor underlying the various forms of psychopathology should be conceptualized in terms of the absence of resilience, that is, the absence of positive reappraisal mechanisms when faced with adversity. These impairments in the capacity for positive reappraisal seem to provide a comprehensive explanation for the association between the p factor and comorbidity, future caseness, and the 'hard-to-reach' character of many patients with severe personality pathology, most notably borderline personality disorder (BPD)...

There is some research showing that social anxiety is related with attentional bias to threat. However, others fail to find this relationship and propose that gender differences may play a role. The aim of this study was to investigate the gender differences in the subcomponents of attentional bias to threat (hypervigilance and difficulty in disengaging) among children and adolescents with social anxiety. Overall, 181 youngsters aged between 10 and 14 participated in the current study. Images of disgusted faces were used as threat stimuli in an Exogenous Cueing Task was used to measure the subcomponents of attentional bias...

Although rates of child maltreatment are declining, more than 600,000 children in the United States are substantiated victims of abuse or neglect. The focus of this review is on the relationship between maltreatment and mental health problems in childhood and adulthood. Children and adults who are exposed to abuse or neglect in childhood are at risk for a range of poor mental health outcomes, including internalizing and externalizing psychopathology, posttraumatic stress disorder, psychotic symptoms, and personality disorders...

BACKGROUND: Globally the preterm birth rate for 184 countries in 2010 was 11.1%. Preterm births can be a traumatic experience for mothers. OBJECTIVE: This article provides a mixed research synthesis of the quantitative and qualitative studies on posttraumatic stress in mothers who have given birth prematurely. DESIGN: Narrative synthesis was the mixed research synthesis approach used. RESULTS: Included in this narrative synthesis were quantitative prevalence studies ( n = 19), quantitative intervention studies ( n = 6), and qualitative studies ( n = 5)...

Besides fight and flight responses, animals and humans may respond to threat with freezing, a response characterized by bradycardia and physical immobility. Risk assessment is proposed to be enhanced during freezing to promote optimal decision making. Indeed, healthy participants showed freezing-like responses to threat cues. Posttraumatic stress disorder (PTSD) patients are characterized by hypervigilance and increased threat responsiveness. We propose that threat responses will be characterized by decreased freezing in PTSD, eliminating possibilities for rejecting cognitive distortions, such as harm expectancy, and thereby contributing to the maintenance of the disorder...

Although individuals with autism spectrum disorder (ASD) have impaired responses to interpersonal touch, the underlying neural correlates remain largely unknown. Here, we examined the neural correlates that underlie interpersonal touch perception in individuals with either high or low autistic traits. Fifty-three participants were classified as having either high or low autistic traits based on their performance on the autism quotient (AQ) questionnaire. We hypothesized that individuals with high AQ scores would have relatively high touch hypervigilance, reflected as earlier P1 and stronger late positive potential (LPP) responses, two components of event-related potentials that serve as electrophysiological markers of anxiety bias...

OBJECTIVES: Measures of cognitive-affective processes believed to underlie Irritable Bowel Syndrome (IBS) symptom expression are used widely in both clinical and research settings. When combined, these measures can be time-consuming and it is not clear whether they evaluate distinct or overlapping constructs. With this study, we seek to identify the most critical cognitive-affective components contributing toward the expression of IBS and to identify which items in these constructs might be streamlined into a single, brief self-report measure...

BACKGROUND: Childhood maltreatment is a potent predictor of poor mental health across the life span. We argue that there is a need to improve the understanding of the mechanisms that confer psychiatric vulnerability following maltreatment, if we are to progress from simply treating those with a manifest disorder, to developing effective preventative approaches that can help offset the likelihood that such disorders will emerge in the first place. METHODS: We review extant functional neuroimaging studies of children and adolescents exposed to early neglect and/or maltreatment, including physical, sexual and emotional abuse across four neurocognitive domains: threat processing, reward processing, emotion regulation and executive control...

The widely publicized violent encounters between police and African American youth have unknown consequences for the emotional and mental health of pregnant African American women. Since studies document the hypervigilance black mothers exert to protect children from violence and racism and findings also reveal the association between racial and gendered stress (which includes parenting stressors) and depressive symptoms during pregnancy, an examination of the effects of stress from anticipated negative experiences between black youth and police on maternal mental health is warranted...

OBJECTIVES: We investigated the potential role of cingulum and uncinate fasciculus integrity in trauma-related neural hypervigilance, indexed by less discrimination between amygdala activation to novel and familiar affective images. PARTICIPANTS: 22 women (mean age 21.7 ± 3.9 years) with a history of trauma, and 20 no-trauma controls (mean age 21.9 ± 4.8 years). MEASURES: Trauma exposure and trauma-related symptoms were assessed during structured clinical interview...

Fear- and stress-induced activity in the amygdala has been hypothesized to influence sensory brain regions through the influence of the amygdala on neuromodulatory centers. To directly examine this relationship, we used optical imaging to observe odor-evoked activity in populations of olfactory bulb inhibitory interneurons and of synaptic terminals of olfactory sensory neurons (the primary sensory neurons of the olfactory system, which provide the initial olfactory input to the brain) during pharmacological inactivation of amygdala and locus coeruleus (LC) in mice...

BACKGROUND: Studies investigating mechanisms underlying nocebo responses in pain have mainly focused on negative expectations induced by verbal suggestions. Herein, we addressed neural and behavioral correlates of nocebo responses induced by classical conditioning in a visceral pain model. METHODS: In two independent studies, a total of 40 healthy volunteers underwent classical conditioning, consisting of repeated pairings of one visual cue (CS(High) ) with rectal distensions of high intensity, while a second cue (CS(Low) ) was always followed by low-intensity distensions...
