Underlying neurobiology and clinical correlates of mania status after subthalamic nucleus deep brain stimulation in Parkinson's Disease : a review of the literature

Deep brain stimulation (DBS) is a novel and effective surgical intervention for refractory Parkinson's disease (PD). The authors review the current literature to identify the clinical correlates associated with subthalamic nucleus (STN) DBS-induced hypomania/mania in PD patients. Ventromedial electrode placement has been most consistently implicated in the induction of STN DBS-induced mania. There is some evidence of symptom amelioration when electrode placement is switched to a more dorsolateral contact. Additional clinical correlates may include unipolar stimulation, higher voltage (>3 V), male sex, and/or early-onset PD. STN DBS-induced psychiatric adverse events emphasize the need for comprehensive psychiatric presurgical evaluation and follow-up in PD patients. Animal studies and prospective clinical research, combined with advanced neuroimaging techniques, are needed to identify clinical correlates and underlying neurobiological mechanisms of STN DBS-induced mania. Such working models would serve to further our understanding of the neurobiological underpinnings of mania and contribute valuable new insight toward development of future DBS mood-stabilization therapies.

Understanding data quality issues in dynamic organisational environments – a literature review

Technology has been the catalyst that has facilitated an explosion of organisational data in terms of its velocity, variety, and volume, resulting in a greater depth and breadth of potentially valuable information, previously unutilised. The variety of data accessible to organisations extends beyond traditional structured data to now encompass previously unobtainable and difficult to analyse unstructured data. In addition to exploiting data, organisations are now facing an even greater challenge of assessing data quality and identifying the impacts of lack of quality. The aim of this research is to contribute to data quality literature, focusing on improving a current understanding of business-related Data Quality (DQ) issues facing organisations. This review builds on existing Information Systems literature, and proposes further research in this area. Our findings confirm that the current literature lags in recognising new types of data and imminent DQ impacts facing organisations in today’s dynamic environment of the so-called “Big Data”. Insights clearly identify the need for further research on DQ, in particular in relation to unstructured data. It also raises questions regarding new DQ impacts and implications for organisations, in their quest to leverage the variety of available data types to provide richer insights.

Towards a better understanding of how effective IT governance leads to business value : a literature review and future research directions

This paper reviews the existing literature on IT governance to assess whether IT governance has contributed to delivering business value from IT and if so, how. The conducted literature review has shown the scarce number of studies that focus on why and how effective IT governance may lead to business value. By using a structured literature review analysis, the paper has offered a number of insights to the topic of IT governance: a) provided a systematic definition of effective IT governance based on a multi-dimensional framework, b) listed benefits of effective IT governance, and c) identified mechanisms that lead effective IT governance to those benefits. This paper takes a step towards addressing the ‘why’ and ‘how’ knowledge gaps by synthesising the fragmented knowledge to provide the best that is known about the subject and to identify future research directions.

A review of the literature exploring the occupation of contemporary pilgrimage

Contemporary pilgrimage is a multi-dimensional, diverse and evolving occupation, not limited to overtly religious intentions or practices, which has not been explored in the occupational science literature. The purpose of this paper is to present an overview of the scholarly discourse as an important initial step toward understanding the occupation of pilgrimage and its impact on well-being. The discovery process within the literature was strategically refined yielding occupational science's first view of this expanding field of enquiry. This paper introduces the scope of the topic, defines key terms and explores the range of participation in contemporary pilgrimage. International evidence of increased popular interest and participation in pilgrimage is discussed, and the interdisciplinary evidence of the benefits to health and well-being experienced by pilgrims is summarised. This paper argues that occupational science could take a leading role in investigating the relationship between participation in pilgrimage and the experience of well-being for a range of people and populations.

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.

Arson treatment programmes for offenders with disability : a systematic review of the literature

Purpose – The purpose of this paper is to identify and evaluate treatment for adult fire setters with an intellectual disability, given the specific risks they present, the complexities of criminal proceedings associated with their behaviour, and subsequent rehabilitation. However, the review also took into account programmes for fire setters in the wider population, including those for children and adolescents, given that such research might also inform the development of programmes for offenders with an intellectual disability.

Design/methodology/approach – A systematic review of the literature was undertaken.

Findings – Only four studies which evaluated treatment programmes specifically for arsonists with an intellectual disability were identified. Although each of these studies reported a reduction in fire-setting behaviour following programme completion, all employed relatively weak research designs. An additional 12 studies investigating programmes for arsonists without intellectual disability were also identified. It is concluded that there is a lack of evidence regarding treatment programme outcomes for arsonists with an intellectual disability. The extent to which such programmes can be adapted to suit adult offenders with an intellectual disability is discussed, with recommendations made for the design and evaluation of arson treatment programmes for offenders with intellectual disabilities.

Originality/value – Currently, minimal treatments programs exist for fire setting in offenders with intellectual disability. This review highlights the importance of further research into treatment programs for this specialised population.

Information needs of young adults with type 2 diabetes : a literature review

Background Type 2 diabetes (T2DM) is increasingly prevalent in young adults but there is very little information about what information they need to undertake diabetes self-management.

Aim To undertake a structured literature review to identify what information people with type 2 diabetes aged 25 to 45 years need to manage their diabetes and how they would like to receive it.

Methods A structured literature search was conducted. The MEDLINE, CINAHL, AMI, APAIS-Health databases were searched for articles published between 1980 and 2011. The reference list of journals and relevant websites were searched. Inclusion criteria were: literature about T2DM in young adults and literature about education and information needs of young adults with T2DM.

Results Only one article specifically focussed on the information needs of young people with T2DM and two reports included some information about T2DM and young adults. The limited data available suggested young adults with T2DM have specific information needs that are not sufficiently addressed in current resources, and have some needs different from young people with type 1 diabetes. Young people with T2DM want clear, consistent information from credible sources, delivered in a range of formats. They also want psychological support and counselling, age-specific education groups, after hours access to health professionals and education provided to family members and the community about T2DM in young people and about how to support people with T2DM.

Conclusion With the prevalence of T2DM in young adults continuing to increase, the need to address the specific information needs and learning styles of people with T2DM aged 25 to 45 is increasingly important.
