Selected AbstractsAcute cognitive effects of standardised Ginkgo biloba extract complexed with phosphatidylserineHUMAN PSYCHOPHARMACOLOGY: CLINICAL AND EXPERIMENTAL, Issue 4 2007D. O. Kennedy Abstract Recent data suggest that the complexation of standardised Ginkgo biloba extract (GBE) with soy-derived phospholipids enhances the bio-availablity of GBE's active components. The current study therefore aimed to assess the comparative cognitive and mood effects of a low dose of GBE and products complexing the same extract with either phosphatidylserine or phosphatidylcholine. The study utilised a placebo-controlled, multi-dose, double-blind, balanced-crossover design. Twenty-eight healthy young participants received 120,mg GBE, 120,mg GBE complexed with phosphatidylserine (VirtivaÔ), 120,mg GBE complexed with phosphatidylcholine and a matching placebo, on separate days 7 days apart. Cognitive performance was assessed using the Cognitive Drug Research (CDR) computerised test battery and Serial Subtraction tasks immediately prior to dosing and at 1, 2.5, 4 and 6,h thereafter. The primary outcome measures were the four aspects of cognitive performance, which have previously been derived by factor analysis of CDR subtests. Levels of terpenoids (bilobalide, ginkgolide A and ginkgolide B) were concomitantly assessed in plasma samples taken pre-dose and at 3 and 6.5,h post-dose. In keeping with previous research utilising the same methodology, 120,mg of GBE was not associated with markedly improved performance on the primary outcomes. However, administration of GBE complexed with phosphatidylserine resulted both in improved secondary memory performance and significantly increased speed of memory task performance across all of the post-dose testing sessions. Enhancement following GBE complexed with phosphatidylcholine was restricted to a modest improvement in secondary memory performance which was restricted to one post-dose time point. All three treatments were associated with improved calmness. There were no significant differences in post-dose levels of terpenoids between the Ginkgo containing treatments, although this latter finding may be attributable to methodological factors. Complexation with phosphatidylserine appears to potentiate the cognitive effects associated with a low dose of GBE. Further research is required to identify whether this effect is due to the complexation of the extracts, their mere combination, or the separate psychopharmacological actions of the two extracts.

C. De Schipper Abstract Background Attachment research has shown the importance of attachment behaviour for the prevention of dysregulated behaviour due to emotional distress. The support of an attachment figure may be especially important for people with intellectual disability (ID), because they are less adept in dealing with stressful situations on their own. Our purpose was to examine the role of support staff as targets of attachment behaviour for young people with ID by testing the hypothesis that young people who more often engage in attachment interactions with group care staff are less at risk for challenging behaviours. The study design included professional caregivers' report of young persons' attachment behaviour across different relationships to address the relationship-specific nature of attachment behaviour in a group care context. Methods Support staff rated attachment behaviour of 156 young participants with moderate to severe ID who were attending a group care setting. For each participant, we asked two members of the classroom support staff to fill out the Secure Base Safe Haven Observation list. One of them also rated challenging behaviour (Abberant Behavior Checklist). Results Young people who showed more secure attachment behaviour towards professional caregivers were less irritable, less lethargic and less stereotypic in their behaviour, even if we controlled for developmental age and Autism Spectrum Disorders. Two results point in the direction of relationship-specific attachment behaviour: the absence of high consistency in a person's attachment behaviour towards two different caregivers and the independent contribution of each of these relationships to explaining differences in lethargy and stereotypies. A certain preference in attachment behaviour towards specific caregivers was not associated with challenging behaviour. Conclusions Findings suggest that attachment behaviour may be part of young persons' adaptation to the stresses and challenges of group care. Furthermore, adaptation may be determined by the integration of relationships with support staff, because each relationship with a care staff member bears uniquely on challenging behaviour. [source] The influence of age on gait parameters during the transition from a wide to a narrow pathwayPHYSIOTHERAPY RESEARCH INTERNATIONAL, Issue 2 2008Nataliya Shkuratova Abstract Background and Purpose.,The ability to negotiate pathways of different widths is a prerequisite of daily living. However, only a few studies have investigated changes in gait parameters in response to walking on narrow pathways. The aim of this study is to examine the influence of age on gait adjustments during the transition from a wide to a narrow pathway.,Method.,DESIGN: Two-group repeated measures design. SETTING: Gait Laboratory. PARTICIPANTS: Twenty healthy older participants (mean [M] = 74.3 years, Standard deviation [SD] = 7.2 years); 20 healthy young participants (M = 26.6 years, SD = 6.1 years).,Interventions.,Making the transition from walking on a wide pathway (68,cm) to walking on a narrow pathway (15,cm). MAIN OUTCOME MEASURES: Step length, step time, step width, double support time and base of support. Results.,Healthy older participants were able to make the transition from a wide to a narrow pathway successfully. There was only one significant interaction, between age and base of support (p < 0.003). Older adults decreased their base of support only when negotiating the transition step, while young participants started decreasing their base of support prior to the negotiation of transition step (p < 0.01). Conclusion.,Adjustments to the transition from a wide to a narrow pathway are largely unaffected by normal ageing. Difficulties in making the transition to a narrow pathway during walking should not be attributed to normal age-related changes. Copyright © 2008 John Wiley & Sons, Ltd.

This article examines the involvement of adults within participatory forums in English schools and local authorities. Drawing on empirical data from research on children's participation in pupil and civic councils, the article discusses the complex and sometimes contradictory pressures on adults in their advisory roles with young participants. The article goes on to explore these roles within a broader conceptual framework that counterposes children's ,places' with children's ,spaces'. [source] Having a say in health: involving young people with a chronic illness or physical disability in local health services developmentCHILDREN & SOCIETY, Issue 4 2003Jane Lightfoot Increasing attention is being paid to involving users in local NHS service development, and to involving young people as users in their own right. However, we know little about the views and experiences of young participants, especially those with a chronic illness or physical disability, which could inform more effective approaches to their involvement. The paper reports on research investigating the views of young patients and staff who have taken part in NHS service development projects, and suggests a range of issues for consideration when involving young patients in future.

[source] Coupling between limb tremor and postural sway in Parkinson's diseaseMOVEMENT DISORDERS, Issue 3 2008Graham Kerr BSc, MPhED Abstract Increased tremor and postural instability are motor problems commonly associated with Parkinson's disease (PD). Despite the similarity between these oscillatory forms, little is known about the relation between them, especially for individuals with enhanced tremor. This study was designed to examine the nature of any relation between center of pressure (COP) excursions and postural/resting limb tremor of young, older individuals, and Parkinsonian participants in their different medication states. The resting and postural tremor for the PD participants was characterized by a single, prominent peak frequency between 4 and 7 Hz. The postural tremor for young/older participants contained smaller peaks between 1 to 4 and 7 to 12 Hz although no prominent peak was seen in their resting tremor. The AP and ML COP dynamics of all participants was characterized by a major peak between 0.1 and 0.5 Hz. An additional peak was observed in the COP output of the PD participants between 4 and 7 Hz. While no tremor-COP coupling was observed for the young/old groups, coherence analysis revealed a significant degree of coupling between COP motion and tremor between 4 and 7 Hz for PD participants. These results highlight that the amplified tremor in PD can manifest itself in COP dynamics. This finding may have implications for postural stability for this patient group. © 2007 Movement Disorder Society [source] |
