Towards growing Indigenous culturally competent legal professionals in Australia

The Review of Australian Higher Education (Bradley Review: 2008) identified the need for tertiary institutions to incorporate Indigenous knowledges into curriculum to improve educational outcomes for Indigenous Australians and to increase the cultural competency of all students. It recommended that higher education providers ensure that the institutional culture, the cultural competence of staff and the nature of the curriculum supports the participation of Indigenous students, and that Indigenous knowledge be embedded into curriculum so that all students have an understanding of Indigenous culture. While cultural competency has been recognised as an essential element of professional practice in health services internationally, and legal practice in the United States, very little work has been done to promote the cultural competency of legal professionals in the Australian context. This paper will discuss a pilot cultural competency professional development program for legal academics at Queensland University of Technology (Brisbane) developed with the assistance of a Faculty of Law Teaching and Learning Grant in 2011-2012, and tell one Murri’s journey to foster Indigenous cultural competency in an Australian law school.

Validation of the interRAI Cognitive Performance Scale against independent clinical diagnosis and the Mini-Mental State Examination in older hospitalized patients

Objective To compare the diagnostic accuracy of the interRAI Acute Care (AC) Cognitive Performance Scale (CPS2) and the Mini-Mental State Examination (MMSE), against independent clinical diagnosis for detecting dementia in older hospitalized patients. Design, Setting, and Participants The study was part of a prospective observational cohort study of patients aged ≥70 years admitted to four acute hospitals in Queensland, Australia, between 2008 and 2010. Recruitment was consecutive and patients expected to remain in hospital for ≥48 hours were eligible to participate. Data for 462 patients were available for this study. Measurements Trained research nurses completed comprehensive geriatric assessments and administered the interRAI AC and MMSE to patients. Two physicians independently reviewed patients’ medical records and assessments to establish the diagnosis of dementia. Indicators of diagnostic accuracy included sensitivity, specificity, predictive values, likelihood ratios and areas under receiver (AUC) operating characteristic curves. Results 85 patients (18.4%) were considered to have dementia according to independent clinical diagnosis. The sensitivity of the CPS2 [0.68 (95%CI: 0.58–0.77)] was not statistically different to the MMSE [0.75 (0.64–0.83)] in predicting physician diagnosed dementia. The AUCs for the 2 instruments were also not statistically different: CPS2 AUC = 0.83 (95%CI: 0.78–0.89) and MMSE AUC = 0.87 (95%CI: 0.83–0.91), while the CPS2 demonstrated higher specificity [0.92 95%CI: 0.89–0.95)] than the MMSE [0.82 (0.77–0.85)]. Agreement between the CPS2 and clinical diagnosis was substantial (87.4%; κ=0.61). Conclusion The CPS2 appears to be a reliable screening tool for assessing cognitive impairment in acutely unwell older hospitalized patients. These findings add to the growing body of evidence supporting the utility of the interRAI AC, within which the CPS2 is embedded. The interRAI AC offers the advantage of being able to accurately screen for both dementia and delirium without the need to use additional assessments, thus increasing assessment efficiency.

Promising interventions for reducing Indigenous juvenile offending

Indigenous juveniles (those aged 10 to 16 years in Queensland and 10 to 17 years in all other jurisdictions) are over-represented at all stages of the criminal justice system, and their over-representation becomes more pronounced at the most severe end of the system (ie in detention). Recent figures show that Indigenous juveniles are 24 times as likely to be detained in a juvenile correctional facility as non-Indigenous juveniles (Richards & Lyneham 2010). A variety of explanations for this over-representation have been proposed, including: • lack of access or disparate access to diversionary programs (Allard et al. 2010; Cunneen 2008; Snowball 2008); • systemic discrimination against Indigenous juveniles (eg police bias against Indigenous juveniles) (Cunneen 2008; Kenny & Lennings 2007); • inadequate resourcing of Aboriginal legal services (Cunneen & Schwartz 2008); and • genuinely higher levels of offending by Indigenous juveniles (Kenny & Lennings 2007; Weatherburn et al. 2003). A range of measures (including diversion and juvenile conferencing programs) has recently been implemented to reduce the over-representation of Indigenous juveniles in detention, and minimise the contact of juveniles with the formal criminal justice system. Diversionary measures can only have a limited impact, however, and reducing offending and reoffending have been identified as critical factors to address if the over-representation of Indigenous juveniles is to be reduced (Allard et al. 2010; Weatherburn et al. 2003). While acknowledging that other measures designed to reduce the over-representation of Indigenous juveniles are important, this paper reviews the evidence on policies and programs that reduce offending by Indigenous juveniles in Australia. Where relevant, research from comparable jurisdictions, such as New Zealand and Canada, is also discussed.

Angiogenesis is an independent prognostic factor in malignant mesothelioma

Angiogenesis is essential for tumour growth beyond 1 to 2 mm in diameter. The clinical relevance of angiogenesis, as assessed by microvessel density (MVD), is unclear in malignant mesothelioma (MM). Immunohistochemistry was performed on 104 archival, paraffin-embedded, surgically resected MM samples with an anti-CD34 monoclonal antibody, using the Streptavidin-biotin complex immunoperoxidase technique. 93 cases were suitable for microvessel quantification. MVD was obtained from 3 intratumoural hotspots, using a Chalkley eyepiece graticule at × 250 power. MVD was correlated with survival by Kaplan-Meier and log-rank analysis. A stepwise, multivariate Cox model was used to compare MVD with known prognostic factors and the EORTC and CALGB prognostic scoring systems. Overall median survival from the date of diagnosis was 5.0 months. Increasing MVD was a poor prognostic factor in univariate analysis (P = 0.02). Independent indicators of poor prognosis in multivariate analysis were non-epithelial cell type (P = 0.002), performance status > 0 (P = 0.003) and increasing MVD (P = 0.01). In multivariate Cox analysis, MVD contributed independently to the EORTC (P = 0.006), but not to the CALGB (P = 0.1), prognostic groups. Angiogenesis, as assessed by MVD, is a poor prognostic factor in MM, independent of other clinicopathological variables and the EORTC prognostic scoring system. Further work is required to assess the prognostic importance of angiogenic regulatory factors in this disease. © 2001 Cancer Research Campaign.

Vorinostat/SAHA-induced apoptosis in malignant mesothelioma is FLIP/caspase 8-dependent and HR23B-independent

Introduction: Malignant pleural mesothelioma (MPM) is a rapidly fatal malignancy that is increasing in incidence. The caspase 8 inhibitor FLIP is an anti-apoptotic protein over-expressed in several cancer types including MPM. The histone deacetylase (HDAC) inhibitor Vorinostat (SAHA) is currently being evaluated in relapsed mesothelioma. We examined the roles of FLIP and caspase 8 in regulating SAHA-induced apoptosis in MPM. Methods: The mechanism of SAHA-induced apoptosis was assessed in 7 MPM cell lines and in a multicellular spheroid model. SiRNA and overexpression approaches were used, and cell death was assessed by flow cytometry, Western blotting and clonogenic assays. Results: RNAi-mediated FLIP silencing resulted in caspase 8-dependent apoptosis in MPM cell line models. SAHA potently down-regulated FLIP protein expression in all 7 MPM cell lines and in a multicellular spheroid model of MPM. In 6/7 MPM cell lines, SAHA treatment resulted in significant levels of apoptosis induction. Moreover, this apoptosis was caspase 8-dependent in all six sensitive cell lines. SAHA-induced apoptosis was also inhibited by stable FLIP overexpression. In contrast, down-regulation of HR23B, a candidate predictive biomarker for HDAC inhibitors, significantly inhibited SAHA-induced apoptosis in only 1/6 SAHA-sensitive MPM cell lines. Analysis of MPM patient samples demonstrated significant inter-patient variations in FLIP and caspase 8 expressions. In addition, SAHA enhanced cisplatin-induced apoptosis in a FLIP-dependent manner. Conclusions: These results indicate that FLIP is a major target for SAHA in MPM and identifies FLIP, caspase 8 and associated signalling molecules as candidate biomarkers for SAHA in this disease. © 2011 Elsevier Ltd.

Re-imagining youth justice

Persistent high levels of recidivism among young offenders (Luke and Lind 2002; Weatherburn et al. 2012) and the over‐representation of Indigenous young people (Cunneen and White 2011; Snowball 2008; Tauri 2012) have long been features of youth justice in Australia. Other problems – such as the increased rates of young people committing sex offences (Dwyer 2011; O’Brien 2010), increasing numbers of young people criminalised for new offences such as ‘sexting’ (Lee and McGovern 2013), and increasing numbers of young female offenders being drawn into youth justice systems (Carrington 2006; Carrington and Pereira 2009) – have emerged more recently. In this paper, we draw on the concept of ‘imaginary penalities’ (Carlen 2010) to argue these chronic problems are partly informed by ‘imaginary’ understandings of how and why young people (re)offend; reflect ‘imaginary’ understandings of what works to address young people’s (re)offending; and reflect ‘imaginary’ ideals about the primary purposes of the youth justice system. We acknowledge up front that answers to these questions require a great deal of new empirical research. This paper is only a beginning that sets out exactly what such an ambitious project might look like.

Submission to the inquiry into the high level of involvement of Indigenous juveniles and young adults in the criminal justice system

Introduction • The Australian Institute of Criminology (AIC) is Australia's national research and knowledge centre on crime and justice. • The Institute seeks to promote justice and reduce crime by undertaking and communicating evidence-based research to inform policy and practice. • The AIC is governed by the Criminology Research Act and has been in operation since 1973. • The AIC is pleased to have the opportunity to contribute to the Committee's Inquiry into the high level of involvement of Indigenous juveniles and young adults in the criminal justice system. • There is a great deal of evidence to demonstrate that Indigenous young people are significantly over-represented at every stage of the criminal justice system in Australia.

Cyclooxygenase-2 protein levels are independent of epidermal growth factor receptor expression or activation in operable non-small cell lung cancer

Both cyclooxygenase (COX)-2 and epidermal growth factor receptor (EGFR) are thought to play important roles in the pathogenesis of non-small cell lung cancer (NSCLC). A number of in vitro studies have postulated a link between EGFR activation and subsequent COX-2 upregulation. The relationship between these factors has not been established in patients with NSCLC. COX-2 and EGFR expression were studied in 172 NSCLC specimens using standard immunohistochemical techniques. Western blotting was used to determine COX-2 and EGFR levels in five NSCLC cell lines. The effect of treatment with EGF on COX-2 expression in A549 cells was assessed. Results: Both EGFR and COX-2 are overexpressed in NSCLC. The predominant pattern of COX-2 and EGFR staining was cytoplasmic. Membranous EGFR staining was seen in 23.3% of cases. There was no relationship between COX-2 and EGFR expression and survival or any clinicopathological features. No correlation was seen between EGFR expression and COX-2 expression in the immunohistochemical series or in the cell lines. Treatment with EGF did not upregulate COX-2 levels in A549 cells, either in serum free or serum-supplemented conditions. Conclusions: Although COX-2 and EGFR are over-expressed in NSCLC neither was of prognostic significance in this series of cases. There is no correlation between these two factors in either tumour samples or cell lines. Although these factors show no correlation in NSCLC, they remain potential, though independent targets for treatment. © 2004 Elsevier Ireland Ltd. All rights reserved.

Negotiating disability and colonisation : the lived experience of Indigenous Australians with a disability

Disability among Indigenous Australians lies at a nexus between the ongoing impact of European settlement from 1788 and the social effects of living with a disability. Colonisation, with its political, social, economic and cultural concomitants, continues to impact on Indigenous experience, extending to the institutions and services concerned with disability. There is little attention paid to Indigenous Australian disability in general, and the need to decolonise disability has recently been emphasised. Ethnographic research in Brisbane, Australia among Indigenous people with a disability (mostly related to diabetes) confirms the ongoing impact of colonisation. While this experience pervades all aspects of their lives, it also moderates their experience of living with a disability in positive ways. However, while individuals can negotiate their personal experience of disability, the decolonisation of disability services presents challenges that need to be addressed.

Commentary on Nutrition and older Indigenous Australians : service delivery implications in remote communities. A narrative review

Indigenous Australians are the most socially and economically disadvantaged population group in Australia and have the poorest health status. The statistics describe and highlight the degree of sicknesses and disadvantage along with lower life expectancy, elevated mortality rate and increased risk of cardiovascular disease, cancer, diabetes, respiratory disease and kidney disease. While these statistics reflect poor health status and a high level of illness within Indigenous communities, it is known that individual, family and community behaviours play a key role in Indigenous health and wellbeing outcomes. These behavioural issues include use of tobacco, alcohol and other substances along with lack of physical activity and poor nutrition. The paper Nutrition and older Indigenous Australians: Service delivery implications in remote communities. A narrative view explores some of the issues specific to nutrition. Bronwyn Fredericks was invited to provide this commentary by the Editor of the Australasian Journal on Aging.

Always “tasty”, regardless: Art, chocolate and Indigenous Australians

This paper examines race and colour through the metaphor of chocolate. The authors use the metaphor of chocolate to question why some Aboriginal people are chosen ahead of others, with the choosing done by non-Indigenous people, perhaps on the basis of who is most likely to be “soft-centred”, agreeable, and pliable. The authors discuss the development of the Hot Chocolate art exhibition in Adelaide in 2012, with a particular focus on the works of Pamela CroftWarcon. The exhibition combined chocolate (the food), lyrics from Hot Chocolate (the band), and chocolate (the metaphor for skin colour) to encourage visitors to question their assumptions about representations of Aboriginal people in Australia.

Tumour necrosis is an independent prognostic marker in non-small cell lung cancer : correlation with biological variables

Background Tumour necrosis (TN) is recognized to be a consequence of chronic cellular hypoxia. TN and hypoxia correlate with poor prognosis in solid tumours. Methods In a retrospective study the prognostic implications of the extent of TN was evaluated in non-small cell lung cancer (NSCLC) and correlated with clinicopathological variables and expression of epidermal growth factor receptor, Bcl-2, p53 and matrix metalloproteinase-9 (MMP-9). Tissue specimens from 178 surgically resected cases of stage I-IIIA NSCLC with curative intent were studied. The specimens were routinely processed, formalin-fixed and paraffin-embedded. TN was graded as extensive or either limited or absent by two independent observers; disagreements were resolved using a double-headed microscope. The degree of reproducibility was estimated by re-interpreting 40 randomly selected cases after a 4 month interval. Results Reproducibility was attained in 36/40 cases, Kappa score=0.8 P<0.001. TN correlated with T-stage (P=0.001), platelet count (P=0.004) and p53 expression (P=0.031). Near significant associations of TN with N-stage (P=0.063) and MMP-9 expression (P=0.058) were seen. No association was found with angiogenesis (P=0.98). On univariate (P=0.0016) and multivariate analysis (P=0.023) TN was prognostic. Conclusion These results indicate that extensive TN reflects an aggressive tumour phenotype in NSCLC and may improve the predictive power of the TMN staging system. The lack of association between TN and angiogenesis may be important although these variables were not evaluated on serial sections. © 2002 Elsevier Science Ireland Ltd. All rights reserved.
