The impact of computer display height and desk design on 3D posture during information technology work by young adults

Computer display height and desk design to allow forearm support are two critical design features of workstations for information technology tasks. However there is currently no 3D description of head and neck posture with different computer display heights and no direct comparison to paper based information technology tasks. There is also inconsistent evidence on the effect of forearm support on posture and no evidence on whether these features interact. This study compared the 3D head, neck and upper limb postures of 18 male and 18 female young adults whilst working with different display and desk design conditions. There was no substantial interaction between display height and desk design. Lower display heights increased head and neck flexion with more spinal asymmetry when working with paper. The curved desk, designed to provide forearm support, increased scapula elevation/protraction and shoulder flexion/abduction.

Talking it up! Project report : Aboriginal voices in the formulation of health policy that works : short report

Initially, there were three separate strands to the work of the project: a series of forums involving group interviews/discussions with community members; a policy analysis that reviewed policies relating to Aboriginal health at federal and state level; and a literature review. The results of these three separate strands of analysis were then brought together in a fourth strand to the work, a process involving community members to discuss and agree the overall recommendations contained in this report.

Through this structure, the project employed a participatory methodology as the basis for individual and collective empowerment in relation to health outcomes. As mentioned above, the need for the project was identified by Aboriginal people, through their own processes of healing. The need was presented by appropriate figures within their communities, namely community elders. They invited other Aboriginal people to take part through their own communication channels, thus ensuring that responsibility for engagement in the project, and in formulating action for improvement, remained with Aboriginal people and their families. However, the project design also recognised that Aboriginal people exist within broader structural and policy constraints which impact on their ability to manage their own lives successfully or otherwise. Thus the project sought to combine indigenous and non-indigenous knowledge through bringing together the three strands of work in the way described.

A Community Reference Group guided the work of the project at all stages, endorsed the findings and drafted the recommendations. The two elders who had identified the need for the project formed the core of the group, and worked on the project from start to finish. At different times during the project, other community members joined the group to assist in its work, including training Aboriginal researchers, letting others know about the forums, discussing findings and drafting recommendations.

Factors influencing consistency of triage using the Australasian triage scale : implications for guideline development

Objective: To examine the influence of the nurse, the type of patient presentation and the level of hospital service on consistency of triage using the Australasian Triage Scale.

Methods: A secondary analysis of survey data was conducted. The main study was undertaken to measure the reliability of 237 scenarios for inclusion in a national training programme. Nurses were recruited from a quota sample of Australian ED according to peer group. Analysis was performed to determine concordance: the percentage of responses in the modal triage category. Analysis of variance (anova) and Pearson correlations were used to investigate associations between the explanatory variables and concordance.

Results: A total of 42/50 (84%) participants returned questionnaires, providing 9946 scenario responses for analysis. Significant differences in concordance were observed by variables describing the type of patient presentation and level of urgency. Mean scores for the comparison group (adult pain; 70.7%) were higher than the groups involving a mental health or pregnancy presentations (61.4%; P≤ 0.001; 65.0%; P= 0.02). Modal responses at the extreme ends of the scale were higher than in the middle categories (P≤ 0.001). There was a significant main effect on concordance by type of service according to peer group (P= 0.03). Of the nine variables that described nurse characteristics, age was the only factor to influence the outcome (P= 0.05).

Conclusion: We identified significant problems with the consistency of triage for mental health and pregnancy presentations. Further research is needed to improve the guidelines on the implementation of the Australasian Triage Scale for these populations.

Effect of timing of dialysis commencement on clincial outcomes of patients with planned initiation of peritoneal dialysis in the ideal trial

Background: Since the mid-1990s, early dialysis initiation has dramatically increased in many countries. The Initiating Dialysis Early and Late (IDEAL) study demonstrated that, compared with late initiation, planned early initiation of dialysis was associated with comparable clinical outcomes and increased health care costs. Because residual renal function is a key determinant of outcome and is better preserved with peritoneal dialysis (PD), the present pre-specified subgroup analysis of the IDEAL trial examined the effects of early-compared with late-start dialysis on clinical outcomes in patients whose planned therapy at the time of randomization was PD.

Methods: Adults with an estimated glomerular filtration rate (eGFR) of 10 - 15 mL/min/1.73 m2 who planned to be treated with PD were randomly allocated to commence dialysis at an eGFR of 10 - 14 mL/min/1.73 m2 (early start) or 5 - 7 mL/min/1.73 m2 (late start). The primary outcome was all-cause mortality.

Results: Of the 828 IDEAL trial participants, 466 (56%) planned to commence PD and were randomized to early start (n = 233) or late start (n = 233). The median times from randomization to dialysis initiation were, respectively, 2.03 months [interquartile range (IQR):1.67 - 2.30 months] and 7.83 months (IQR: 5.83 - 8.83 months). Death occurred in 102 early-start patients and 96 late-start patients [hazard ratio: 1.04; 95% confidence interval (CI): 0.79 - 1.37]. No differences in composite cardiovascular events, composite infectious deaths, or dialysis-associated complications were observed between the groups. Peritonitis rates were 0.73 episodes (95% CI: 0.65 - 0.82 episodes) per patient-year in the early-start group and 0.69 episodes (95% CI: 0.61 - 0.78 episodes) per patient-year in the late-start group (incidence rate ratio: 1.19; 95% CI: 0.86 - 1.65; p = 0.29). The proportion of patients planning to commence PD who actually initiated dialysis with PD was higher in the early-start group (80% vs 70%, p = 0.01).

Conclusion: Early initiation of dialysis in patients with stage 5 chronic kidney disease who planned to be treated with PD was associated with clinical outcomes comparable to those seen with late dialysis initiation. Compared with early-start patients, late-start patients who had chosen PD as their planned dialysis modality were less likely to commence on PD.

Inclusion in participatory research: what were the whitefellas doing in an Aboriginal health project?

Health research in indigenous communities, like many interactions between such communities and white-dominated institutions, has a chequered history leading to a three-fold decrement: suspicion and resistance to research that is seen as coming from outside of the community; a shortage of research generators and leaders within the community; and cumulative gaps in the research evidence base, both in terms of coverage of topics and in terms of meeting the priorities of the community.

Additionally, these decrements have been mistakenly located as problems being caused from within the community, rather than recognising that these are outcomes of wider contextual, historical and institutional factors and failings. Good research, as culturally appropriate, inclusive of community voices and meeting the needs and priorities of the community, is necessary in an increasingly evidence-based-practice culture within policy and health settings. Culturally safe research with and for indigenous communities has the potential to be empowering, and to bring community voices, views and experiences into the influential realm of'evidence.

This process of developing safe, appropriate and inclusive research is not straightforward: the decrements are recursive, with a shortage of connections between the community, its priorities and research. However, as the Healing Stories project that we discuss here has shown, it is possible to develop culturally safe participatory research by working with Elders from within the community and with leaders from within white institutions, in a spirit of reconciliation. The methods and findings of Healing Stories have been reported elsewhere, with an emphasis on the voices from the community; this chapter explores some of the 'behind the scenes' processes, from the perspective of the white researchers working from within white- dominated institutions.

After briefly describing the Healing Stories project, this chapter reflects on three parts of the participatory research process: getting started, leading together, and working together. The first of these considers laying the foundations for participatory research, working with Elders and leaders, and planning for inclusion, examining participatory research as a recognisable research design, with potential for rigour, cultural safety and inclusion. The second explores developing participatory methods, working with communities, and opportunities and choices for inclusion. The third examines the process of being participatory, working together and engaging in inclusion across the long-term commitment to the project.

Promoting social inclusion of frail older people living in the community

The increasingly diverse needs and wants of Australia's ageing population, like those in many other societies, are drawing attention to aged care as an increasingly important area of broader health and social policy. Active qgeing and a focus on enabling people to remain living in their own homes in the community are two of the key components of this policy shift.

The policy shift towards active ageing recognises and aims to support the desires of older people to remain active members of their communities as they age. Active ageing is 'the process of optimising opportunities for physical, social and mental wellbeing throughout the life-course, in order to extend healthy life expectancy, productivity and quality oflife in older age' (AIPC 2008: 26).

According to the World Health Organization (WHO), the rights, needs, preferences and capacities of older people should be central to active ageing policies, and these should be framed by a life-course approach to ageing (WHO 2002). The development of age-friendly communities, social inclusion and engagement are emerging as key policy issues in the context of an ageing population.

Recent research demonstrates the importance of a sense of belonging in maintaining a sense of identity and increasing the wellbeing of an individual. The sense of belonging that comes about through community engagement also plays a role in successful adjustment to ageing, including prolonging good health and reduced risk of entry into residential aged care.

A novel serogenetic approach determines the community prevalence of celiac disease and informs improved diagnostic pathways

Background
Changing perspectives on the natural history of celiac disease (CD), new serology and genetic tests, and amended histological criteria for diagnosis cast doubt on past prevalence estimates for CD. We set out to establish a more accurate prevalence estimate for CD using a novel serogenetic approach.

Methods
The human leukocyte antigen (HLA)-DQ genotype was determined in 356 patients with ‘biopsy-confirmed’ CD, and in two age-stratified, randomly selected community cohorts of 1,390 women and 1,158 men. Sera were screened for CD-specific serology.

Results
Only five ‘biopsy-confirmed’ patients with CD did not possess the susceptibility alleles HLA-DQ2.5, DQ8, or DQ2.2, and four of these were misdiagnoses. HLA-DQ2.5, DQ8, or DQ2.2 was present in 56% of all women and men in the community cohorts. Transglutaminase (TG)-2 IgA and composite TG2/deamidated gliadin peptide (DGP) IgA/IgG were abnormal in 4.6% and 5.6%, respectively, of the community women and 6.9% and 6.9%, respectively, of the community men, but in the screen-positive group, only 71% and 75%, respectively, of women and 65% and 63%, respectively, of men possessed HLA-DQ2.5, DQ8, or DQ2.2. Medical review was possible for 41% of seropositive women and 50% of seropositive men, and led to biopsy-confirmed CD in 10 women (0.7%) and 6 men (0.5%), but based on relative risk for HLA-DQ2.5, DQ8, or DQ2.2 in all TG2 IgA or TG2/DGP IgA/IgG screen-positive subjects, CD affected 1.3% or 1.9%, respectively, of females and 1.3% or 1.2%, respectively, of men. Serogenetic data from these community cohorts indicated that testing screen positives for HLA-DQ, or carrying out HLA-DQ and further serology, could have reduced unnecessary gastroscopies due to false-positive serology by at least 40% and by over 70%, respectively.

Conclusions
Screening with TG2 IgA serology and requiring biopsy confirmation caused the community prevalence of CD to be substantially underestimated. Testing for HLA-DQ genes and confirmatory serology could reduce the numbers of unnecessary gastroscopies.

Unthinkable

'Unthinkable' was an installation comprising drawings and fabric works placed onto a wall painting. This work engages with the gender politics of art criticism through strategies of redrawing and (re)performance, in particular the commentary that Helen Frankenthaler's painting practice was 'unthinkable' without Jackson Pollock.
