Job stress is a large and growing concern in Australia and internationally. This report presents a current snapshot on job stress concepts and measures, an overview of the evidence linking job stress to ill health, estimates of the size of the problem, the benefits of reducing job stress, a summary of the intervention research on ways to prevent and control job stress, an outline of international best practice in job stress intervention and resources for workplace stakeholders to support efforts to implement best practice.

We have investigated the role of bone sialoprotein (BSP), a secreted glycoprotein normally found in bone, in breast cancer progression. To explore functions for BSP in human breast cancer invasion and metastasis, the full-length BSP cDNA was transfected into the MDA-MB-231-BAG human breast cancer cell line under the control of the CMV promoter. Clones expressing BSP and vector control clones were isolated. BSP producing clones showed increased monolayer wound healing, a faster rate of stellate outgrowth in Matrigel and increased rate of invasion into a collagen matrix when compared to control clones. Clones were also examined in models of breast cancer growth and metastasis in vivo. BSP transfected clones showed an increased rate of primary tumor growth following mammary fat pad injection of nude mice. BSP transfected clones and vector control clones metastasized to soft organs and bone at a similar rate after intra-cardiac injection as determined by real-time PCR and X-ray analysis. Although these organs were targets for both BSP transfected and non-transfected cells, the size of the metastatic lesion was shown to be significantly larger for BSP expressing clones. This was determined by real-time PCR analysis for soft organs and by X-ray analysis of bone lesions. For bone this was confirmed by intra-tibial injections of cells in nude mice. We conclude that BSP acts to drive primary and secondary tumor growth of breast cancers in vivo.

Background
Bioelectrical impedance (BIA) represents a simple, inexpensive and non-invasive method that is often used to assess fat-mass (FM) and fat-free mass (FFM) in large population-based cohorts.
Objective
The aim of this study was to describe the reference ranges and examine the influence of age and gender on FM, FFM and skeletal muscle mass (SMM) as well as height-adjusted estimates of FM [fat mass index (FMI)], FFM [fat-free mass index (FFMI)] and SMM [SMM index (SMI)] in a national, population-based cohort of Australian adults.
Design and Participants
The analytical sample included a total of 8,582 adults aged 25–91 years of Europid origin with complete data involved in the cross-sectional 1999–2000 Australian, Diabetes, Obesity and Lifestyle (AusDiab) Study.
Measurements
Bioelectrical impedance analysis was used to examine components of body composition. Demographic information was derived from a household interview.
Results
For both genders, FFM, SMM and SMI decreased linearly from the age of 25 years, with the exception that in men SMI was not related to age and FFM peaked at age 38 years before declining thereafter. The relative loss from peak values to ≥75 years in FFM (6–8%) and SMM (11–15%) was similar between men and women. For FM and FMI, there was a curvilinear relationship with age in both genders, but peak values were detected 6–7 years later in women with a similar relative loss thereafter. For FFMI there was no change with age in men and a modest increase in women.
Conclusion
In Australian adults there is heterogeneity in the age of onset, pattern and magnitude of changes in the different measures of muscle and fat mass derived from BIA, but overall the agerelated losses were similar between men and women.

The project aims to identify, evaluate and make recommendations to improve the pathways by which West Australian (WA) Home and Community Care (HACC) clients access daily living equipment. Otherwise known as assistive technology (AT), these devices are largely non-complex and often low cost. Funded by HACC and conducted within the context of the WA Assessment Framework (WAAF), the project seeks to answer the following question:
The research is designed to inform WA state government policy and Commonwealth HACC government policy in relation to the funding of HACC client access to assistive technology. Whilst set in WA, the topic and findings have relevance to HACC in other Australian states and territories, as well as other aspects of aged care policy, other sectors such as disability, and other areas of inquiry such as competency standards and consumer self-direction.
