Adaptive autobiographical memory in younger and older adults : the indirect association of integrative and instrumental reminiscence with depressive symptoms

Despite the established effectiveness of reminiscence-based interventions for depression, little research exists into the pathways through which specific reminiscence functions are related to depressive symptoms. Drawing on theory of the mechanisms of change in cognitive-reminiscence therapy, the current study tests the hypothesised indirect associations of adaptive integrative and instrumental reminiscence functions with depressive symptoms and whether these relationships might differ among younger and older adults. Questionnaires were completed by a large community sample of the Australian population. Multiple mediation models were tested in two groups: younger adults (n=730, M age=52.24, SD=9.84) and older adults (n=725, M age= 73.59, SD=6.29). Results were consistent across age groups, indicating that there was direct relationship between these reminiscence functions and depressive symptoms, but that integrative reminiscence is indirectly associated with depressive symptoms through meaning in life, self-esteem, and optimism, and that instrumental reminiscence is indirectly associated with depressive symptoms through primary control and self-efficacy. This study provides support for the relationships between constructs underlying the proposed mechanisms of change in cognitive-reminiscence therapy for the treatment of depression, and suggests these relationships are similar for younger and older adults.

Efficacy and adverse effects of venlafaxine in children and adolescents with ADHD : a systematic review of non-controlled and controlled trials

Attention deficit hyperactivity disorder (ADHD) is a common psychiatric disorder in children and adolescents. Stimulants are commonly prescribed for ADHD management. There is clinical trial evidence that some medications with noradrenergic properties such as atomoxetine are effective. It is of theoretical and practical importance if other agents with noradrenergic properties display a comparable pattern of efficacy.
This paper is a systematic review of the efficacy and safety of venlafaxine for treating children and adolescents with ADHD. MEDLINE, Google scholar, Scopus, and Web of science (ISI) databases were electronically searched in July 2012, updated on November 2012. Time and language of publication were not exclusion criteria. Efficacy outcomes were assessed by a valid and reliable parent- and/or teacher-reported instrument to evaluate clinical symptoms. Adverse effects were also evaluated.

There were three uncontrolled trials and only two double blind controlled clinical trials. Venlafaxine appeared effective for treating ADHD. The rates of some adverse effects of venlafaxine were less than those documented for methylphenidate.

While one of the two small controlled trials did not find difference between venlafaxine ad methylphenidate, the other trial reported lower efficacy for venlafaxine. Headache, insomnia, and nausea were among the most common adverse effects.

This systematic review provides preliminary support that venlafaxine may have short term utility in treating ADHD in children and adolescents. However, before recommending venlafaxine for treatment, more robust and larger clinical trials, in particular providing evidence of its long-term efficacy, safety and tolerability are required.

Is a change in mode of travel to school associated with a change in overall physical activity levels in children? Longitudinal results from the SPEEDY study

Background
Children who use active modes of travel (walking or cycling) to school are more physically active than those who use passive (motorised) modes. However, less is known on whether a change in mode of travel to school is associated with a change in children’s physical activity levels. The purpose of this analysis was to investigate the association between change in mode of travel to school and change in overall physical activity levels in children.

Methods
Data from 812 9–10 year old British children (59% girls) who participated in the SPEEDY study were analysed. During the summer terms of 2007 and 2008 participants completed a questionnaire and wore an accelerometer for at least three days. Two-level multiple linear regression models were used to explore the association between change in usual mode of travel to school and change in objectively measured time spent in MVPA.

Results
Compared to children whose reported mode of travel did not change, a change from a passive to an active mode of travel was associated with an increase in daily minutes spent in MVPA (boys: beta 11.59, 95% CI 0.94 to 22.24; girls: beta 11.92, 95% CI 5.00 to 18.84). This increase represented 12% of boys’ and 13% of girls’ total daily time spent in MVPA at follow-up.

Conclusion
This analysis provides further evidence that promoting active travel to school may have a role in contributing to increasing physical activity levels in children.

Body mass index and dental caries in children and adolescents : a systematic review of literature published 2004 to 2011

The objective
The authors undertook an updated systematic review of the relationship between body mass index and dental caries in children and adolescents.
Method
The authors searched Medline, ISI, Cochrane, Scopus, Global Health and CINAHL databases and conducted lateral searches from reference lists for papers published from 2004 to 2011, inclusive. All empirical papers that tested associations between body mass index and dental caries in child and adolescent populations (aged 0 to 18 years) were included.
Results
Dental caries is associated with both high and low body mass index.
Conclusion
A non-linear association between body mass index and dental caries may account for inconsistent findings in previous research. We recommend future research investigate the nature of the association between body mass index and dental caries in samples that include a full range of body mass index scores, and explore how factors such as socioeconomic status mediate the association between body mass index and dental caries.

Oral baclofen in children with cerebral palsy : a double-blind cross-over pilot study

Aim: To assess the effectiveness of oral baclofen in reducing spasticity and improving function in children with cerebral palsy. Methods: A double-blind, randomised cross-over pilot study of oral baclofen versus placebo. Assessment tools included the Goal Attainment Scale, Pediatric Evaluation of Disability Inventory, Modified Tardieu Scale and parent questionnaire. Results: Fifteen children with mean age 7.4 years (SD = 2.7 years) and spastic or spastic/dystonic quadriplegia (Gross Motor Function Classification System Level IV or V) were enrolled. Children scored significantly better on the Goal Attainment Scale with baclofen compared with placebo (F(1,13) = 4.5, P = 0.05). There was no significant difference between baclofen and placebo for the Pediatric Evaluation of Disability Inventory or Modified Tardieu Scale. Parent questionnaire results are described. Conclusion: This pilot study demonstrates that oral baclofen has an effect beyond placebo in improving goal-oriented tasks, such as transfers, in children with spastic quadriplegic cerebral palsy.

Fictional inquiry : an alternative process to inspire creativity in children's co-design projects

Children's creativity is a valuable resource for architectural design, and attempts have been made throughout the world to involve children in the design process of their environments. Previous children's co-design projects often followed a problem solving process, however, this process has limitations in stimulating children's creativity. Research has found that children's creativity is different to adult's creativity: Instead of creative problem solving skills, children's creativity is most evident in their imagination and originality of thinking. Addressing this issue, an alternative process in children's co-design projects was experimented: Fictional Inquiry. In this paper, two case studies are used to illustrate how the fictional inquiry process is applied in children's co-design projects.* These two projects were both joint educational projects between Deakin University and schools in Geelong and Melbourne. Through several weeks' of workshops, children and university architecture students worked in small groups to develop architectural design solutions. It was observed that creative design outcomes have been achieved in these two projects, which suggested that Fictional Inquiry was an effective process to inspire children's creativity. Applying the Fictional Inquiry process, Deakin University is currently working with another school in the Geelong Region, with the aim of achieving creative architectural design outcomes.

Prospective evaluation of respiratory exacerbations in children with cystic fibrosis from newborn screening to 5 years of age

Background Newborn screening allows novel treatments for cystic fibrosis (CF) to be trialled in early childhood before irreversible lung injury occurs. As respiratory exacerbations are a potential trial outcome variable, we determined their rate, duration and clinical features in preschool children with CF; and whether they were associated with growth, lung structure and function at age 5 years. Methods: Respiratory exacerbations were recorded prospectively in Australasian CF Bronchoalveolar Lavage trial subjects from enrolment after newborn screening to age 5 years, when all participants underwent clinical assessment, chest CT scans and spirometry. Results 168 children (88 boys) experienced 2080 exacerbations, at an average rate of 3.66 exacerbations per person-year; 80.1% were community managed and 19.9% required hospital admission. There was an average increase in exacerbation rate of 9% (95% CI 4% to 14%; p<0.001) per year of age. Exacerbation rate differed by site (p<0.001) and was 26% lower (95% CI 12% to 38%) in children receiving 12 months of prophylactic antibiotics. The rate of exacerbations in the first 2 years was associated with reduced forced expiratory volume in 1 s z scores. Ever having a hospitalmanaged exacerbation was associated with bronchiectasis (OR 2.67, 95% CI 1.13 to 6.31) in chest CT scans, and lower weight z scores at 5 years of age (coefficient -0.39, 95% CI -0.74 to -0.05). Conclusions Respiratory exacerbations in young children are markers for progressive CF lung disease and are potential trial outcome measures for novel treatments in this age group.

A school-based education programme to reduce salt intake in children and their families (School-EduSalt): protocol of a cluster randomised controlled trial

The current salt intake is very high for children as well as adults in China. A reduction in salt intake is one of the most cost-effective measures to curb the rapidly growing disease burden attributed to blood pressure and cardiovascular disease in the Chinese population. A lower salt diet starting from childhood has the potential to prevent the development of such conditions. The School-EduSalt (School-based Education Programme to Reduce Salt) study aims to determine whether an education programme targeted at school children can lower salt intake in children and their families.

Diet and sleep in children with attention deficit hyperactivity disorder : Preliminary data in Australian children

Sleep disturbances are common and consequential in children with attention deficit hyperactivity disorder (ADHD). Diet also influences ADHD symptoms. Interrelationships between diet, sleep and behaviour in children diagnosed with ADHD are little studied. We investigated, via parental report, the relationships between sleep and diet in 88 Australian children aged 6—13 years old (M = 8.94, SD = 1.78). This pilot data shows that 30 per cent of the children had sleep disturbance (≥ 2 standard deviations above the mean) with significant relationships between ADHD symptoms, sleep disturbance and diet. Parents who reported more sleep disturbance also reported a higher intake of carbohydrate, fats, and, most particularly, sugar which was also a significant predictor of night time sweating. These findings suggest an interrelationship between diet and sleep in children with ADHD. Given that both sleep and dietary intake are potentially modifiable behaviours within treatment regimes of children with ADHD, further investigation is needed.

Effects of early-life environment and epigenetics on cardiovascular disease risk in children: highlighting the role of twin studies

Cardiovascular disease (CVD) is the leading cause of death worldwide and originates in early life. The exact mechanisms of this early-life origin are unclear, but a likely mediator at the molecular level is epigenetic dysregulation of gene expression. Epigenetic factors have thus been posited as the likely drivers of early-life programming of adult-onset diseases. This review summarizes recent advances in epidemiology and epigenetic research of CVD risk in children, with a particular focus on twin studies. Classic twin studies enable partitioning of phenotypic variance within a population into additive genetic, shared, and nonshared environmental variances, and are invaluable in research in this area. Longitudinal cohort twin studies, in particular, may provide important insights into the role of epigenetics in the pathogenesis of CVD. We describe candidate gene and epigenome-wide association studies (EWASs) and transgenerational epigenetic inheritance of CVD, and discuss the potential for evidence-based interventions. Identifying epigenetic changes associated with CVD-risk biomarkers in children will provide new opportunities to unravel the underlying biological mechanism of the origins of CVD and enable identification of those at risk for early-life interventions to alter the risk trajectory and potentially reduce CVD incidence later in life.
