A preliminary investigation of 4 to 11-year-old children's knowledge and understanding of stress

Objective. To examine children's knowledge, understanding and experience of stress from 4 to 11 years of age across four age groups (4–5, 6–7, 8–9, and 10–11 years old). Methods. A semi-structured interview format was used to elicit information from 50 children about their understanding and experience of stress. Results. Most children were able to define stress, with older children providing more complex responses. Many children had indirect and/or personal experience of stress. Younger children were more likely than older children to report that there was nothing people could do to stop stress; children reported using both adaptive and maladaptive coping strategies to deal with stress. Conclusion. Some young children have a basic understanding of stress and many have experience of stress; both understanding and experience develop with age. Practice Implications. The research has potential implications for provider-patient communication, particularly within preventative health education and clinically within the field of childhood post-traumatic stress disorder (PTSD).

Being there:a qualitative interview study with fathers present during the resuscitation of their baby at delivery

Objective: To explore fathers' experiences of the resuscitation of their baby at delivery. Design: A descriptive, retrospective design using tape-recorded semistructured interviews with fathers present during the resuscitation of their baby at delivery. Fathers described what happened, their interactions with healthcare professionals, their feelings at the time and afterwards. Setting: Participants were recruited from a large teaching hospital in the UK. Participants: A purposive sample of 20 fathers whose baby required resuscitation at delivery. Results: Participant responses were analysed using thematic analysis. Four broad themes were identified: 'preparation', 'knowing what happened', 'his response' and 'impact on him'. Fathers had no difficulty recalling their emotions during the resuscitation. These feelings remained vivid and were mostly negative. Most fathers wanted to go to their baby during the resuscitation but did not do so. They felt they should stay with their partner, did not want to impede the resuscitation or felt they were not 'allowed' to go to their baby. The fathers' position in the room and the extent to which they were focusing on their partner had an impact on their recollection of what happened. Fathers had no opportunity to discuss the resuscitation with healthcare professionals afterwards. Several fathers felt they had not yet recovered from the experience and a few had symptoms synonymous with post-traumatic stress disorder. Conclusion: This is the first study to specifically explore fathers' experiences of newborn resuscitation. The findings should inform healthcare education, policy development and the provision of support to fathers.

Ethosuximide modifies network excitability in the rat entorhinal cortex via an increase in GABA release

Ethosuximide is the drug of choice for treating generalized absence seizures, but its mechanism of action is still a matter of debate. It has long been thought to act by disrupting a thalamic focus via blockade of T-type channels and, thus, generation of spike-wave activity in thalamocortical pathways. However, there is now good evidence that generalized absence seizures may be initiated at a cortical focus and that ethosuximide may target this focus. In the present study we have looked at the effect ethosuximide on glutamate and GABA release at synapses in the rat entorhinal cortex in vitro, using two experimental approaches. Whole-cell patch-clamp studies revealed an increase in spontaneous GABA release by ethosuximide concurrent with no change in glutamate release. This was reflected in studies that estimated global background inhibition and excitation from intracellularly recorded membrane potential fluctuations, where there was a substantial rise in the ratio of network inhibition to excitation, and a concurrent decrease in excitability of neurones embedded in this network. These studies suggest that, in addition to well-characterised effects on ion channels, ethosuximide may directly elevate synaptic inhibition in the cortex and that this could contribute to its anti-absence effects.

Neuropsychiatric manifestations in inflammatory neuropathies:a systematic review

We conducted a systematic literature review on psychological and behavioral comorbidities in patients with inflammatory neuropathies. In Guillain-Barré syndrome (GBS), psychotic symptoms are reported during early stages in 30% of patients. Typical associations include mechanical ventilation, autonomic dysfunction, inability to communicate, and severe weakness. Anxiety and depression are frequent comorbidities. Anxiety may increase post-hospital admissions and be a predictor of mechanical ventilation. Post-traumatic stress disorder may affect up to 20% of ventilated patients. Sleep disturbances are common in early-stage GBS, affecting up to 50% of patients. In chronic inflammatory demyelinating polyradiculoneuropathy, memory and quality of sleep may be impaired. An independent link between depression and pre-treatment upper limb disability and ascites was reported in POEMS (Polyneuropathy, Organomegaly, Endocrinopathy, M-protein, Skin) syndrome, with an association with early death. Hematological treatment of POEMS appears effective on depression. Published literature on psychological/behavioral manifestations in inflammatory neuropathies remains scarce, and further research is needed. This article is protected by copyright.

"I'm a better manager":A biographic narrative study of the impact of personal trauma on the professional lives of managers in the UK

This doctoral study aims to understand how experiences of critical illness or bereavement affect the way managers view and approach their work and their relationships at work. This is an interpretative phenomenological study examining the subjective meanings of personal experience and is underpinned by biographic narratives from four participants and interviews with their nominated workplace witnesses (i.e. colleagues who worked alongside the individual at the time of their trauma). As a consequence of the findings that have emerged across this study, three contributions to theory are presented. All four participants described their traumas as a professional growth experience for themselves as managers, which resulted in self-reported and observed behaviour change at work. Consequently, the first area of theoretical contribution is a suggested extension to the post-traumatic growth (PTG) framework (Calhoun & Tedeschi, 2006) with the addition of a new behavioural dimension called ‘managerial growth’, when applied to the context of ‘ordinary’ organizations. The second area of theoretical contribution arose through the reflexive process that was created during data collection where participants and their witnesses remembered episodes of compassion interaction at work. The second area of contribution thus seeks to extend the existing model of compassion at work (Dutton, Worline, Frost and Lilius, 2006), by conceptualising compassion as a dyadic process between a compassion ‘giver’ and a compassion ‘receiver’ in which the compassion receiver ‘trusts or ‘mistrusts’; ‘discloses’ or ‘withholds’; ‘connects’ or ‘disconnects’ with the compassion giver. The third area of contribution is a new conceptualisation of reflexivity, ‘three-dimensional reflexivity’ (3DR) (Armstrong, Butler and Shaw, 2013). 3DR brings together three of the elements that have been missing from critically reflexive management research; by working with multiple variants of reflexivity in the same study; surfacing different reflexive voices to guard against the researcher’s (potentially) solipsistic own; and remaining sensitive to the concept of reflexive time. In doing so, 3DR not only provides a deeper understanding of individual lived experience; it is also a vehicle in which self-insight is gained. Furthermore, by engaging in its practice, those involved in this study have developed both personally and professionally as a result.

An exploratory study to determine applicability of nano-hardness and micro-compression measurements for yield stress estimation

The superior properties of ferritic/martensitic steels in a radiation environment (low swelling, low activation under irradiation and good corrosion resistance) make them good candidates for structural parts in future reactors and spallation sources. While it cannot substitute for true reactor experiments, irradiation by charged particles from accelerators can reduce the number of reactor experiments and support fundamental research for a better understanding of radiation effects in materials. Based on the nature of low energy accelerator experiments, only a small volume of material can be uniformly irradiated. Micro and nanoscale post irradiation tests thus have to be performed. We show here that nanoindentation and micro-compression testing on T91 and HT-9 stainless steel before and after ion irradiation are useful methods to evaluate the radiation induced hardening.

Adjusting to job relocation:relocation preparation can reduce relocation stress

This study, for the first time, examines the relationship between pre-move relocation preparation with psychological well-being to job relocation. Psychological reactions of 54 relocators were measured before and after their move. The greater the reported pre-move relocation preparation the better was the relocators' post-move mental health and job-related contentment and enthusiasm. Furthermore, pre-move relocation preparation was associated with reduced problems during the move and this, in turn, resulted in better post-move adjustment.

Weight loss strategies, stress, and cognitive function:supervised versus unsupervised dieting

The early stages of dieting to lose weight have been associated with neuro-psychological impairments. Previous work has not elucidated whether these impairments are a function solely of unsupported or supported dieting. Raised cortico-steroid levels have been implicated as a possible causal mechanism. Healthy, overweight, pre-menopausal women were randomised to one of three conditions in which they dieted either as part of a commercially available weight loss group, dieted without any group support or acted as non-dieting controls for 8 weeks. Testing occurred at baseline and at 1, 4 and 8 weeks post baseline. During each session, participants completed measures of simple reaction time, motor speed, vigilance, immediate verbal recall, visuo-spatial processing and (at Week 1 only) executive function. Cortisol levels were gathered at the beginning and 30 min into each test session, via saliva samples. Also, food intake was self-recorded prior to each session and fasting body weight and percentage body fat were measured at each session. Participants in the unsupported diet condition displayed poorer vigilance performance (p=0.001) and impaired executive planning function (p=0.013) (along with a marginally significant trend for poorer visual recall (p=0.089)) after 1 week of dieting. No such impairments were observed in the other two groups. In addition, the unsupported dieters experienced a significant rise in salivary cortisol levels after 1 week of dieting (p<0.001). Both dieting groups lost roughly the same amount of body mass (p=0.011) over the course of the 8 weeks of dieting, although only the unsupported dieters experienced a significant drop in percentage body fat over the course of dieting (p=0.016). The precise causal nature of the relationship between stress, cortisol, unsupported dieting and cognitive function is, however, uncertain and should be the focus of further research. © 2005 Elsevier Ltd.
