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.

Visual stress symptoms secondary to stroke alleviated with spectral filters and precision tinted ophthalmic lenses:a case report

Visual stress is a condition characterised by symptoms of eyestrain, headaches and distortions of visual perception when reading text. The symptoms are frequently alleviated with spectral filters and precision tinted ophthalmic lenses. Visual stress is thought to arise due to cortical hyperexcitability and is associated with a range of neurological conditions. Cortical hyperexcitability is known to occur following stroke. The case presented describes visual stress symptoms resulting from stroke, subsequently managed with spectral filters and precision tinted ophthalmic lenses. The case also highlights that the spectral properties of the tint may need to be modified if the disease course alters.

Autonomic dysfunction and systemic oxidative stress associated with glaucomatous optic neuropathy

There were four principal sections to the work: 1. Investigation of ocular and systemic vascular risk factors in POAG. The principal findings of this work were: a). Glaucoma patients exhibit an anticipatory reaction to the physical stress, similar to subjects at risk for cardiovascular diseases; a blunted BP response and a reduction in ONH blood flow in response to cold provocation was also recorded. b). Silent myocardial ischaemic episodes occurred during peaks in systemic BP and HR. c). Independent of a positive history for cardiovascular diseases, patients suffering from POAG demonstrate a blunt circadian rhythm of the ANS. 2. Assessment of the relationship between vascular and systemic vascular risk factors in GON. The principal findings of this work were: a). POAG patients demonstrate a high sympathetic tonus over a 24-h period. b). POAG patients with lower OBF demonstrate both 24-h systemic BP and HRV abnormalities. c). OBF alterations observed in some glaucoma patients could be either primary or secondary to systemic haemodynamic disturbances and not a consequence of ONH damage. 3. Assessment of the level of systemic anti-oxidant defence in POAG patients. The principal finding of this work was: Patients suffering from POAG demonstrated significantly lower GSH and t-GSH levels than normal controls. 4. Investigation of the effect of treatment with latanoprost 0.005% on visual function and OBF. The findings of this work were: a). Treatment with latanoprost 0.005% resulted in a significant decrease in IOP and increase in OPP. VF damage progression has also been stopped. b). Treatment with latanoprost 0.005% resulted in a significant increase in the OBF parameters measured at the ONH and peripapillary retina levels. Finally, the importance of a clear protocol for managing new POAG cases is highlighted and a clinical conduit is proposed.
