Prevalence of malnutrition risk and its relationship with risk factors of hospital re-admission in older adults

Background: Risk of malnutrition in older people continues to be a global problem. Malnutrition is often unrecognized and under-treated across health care settings and may result in undesirable health consequences, impaired recovery from illness and a poorer quality of life. Aim: This study aimed to determine the prevalence of malnutrition risk in a sample of older people at high risk of hospital re-admission. The association between risk factors of hospital re-admission and risk of malnutrition were also explored. Methods: One hundred and twenty five hospitalised patients aged 65 years and older at risk of hospital readmission (24% male, 76% female, mean age 77 ± 6 years) were recruited from a tertiary metropolitan hospital in Australia. The valid and reliable Malnutrition Screen Tool (MST) was employed to screen for malnutrition risk. It consists of two questions related to recent weight loss and appetite. Results: Prevalence of older adults at risk of malnutrition was 27.4%. Risk of malnutrition was not associated with age, gender and living arrangement. However, among risk factors of hospital readmission, lack of social support (χ2 = 4.18, N = 125, p = 0.028), and fair –poor self-rating of health (χ2 = 4.13, N = 125, p = 0.042) were statistically significant associated with risk of malnutrition. Conclusion: Risk of malnutrition in older people continues to be a concern in health care, and increasing psycho social support may help shed light on reducing risk of malnutrition.

Mind games : applying White’s principles of narrative therapy to the creation of a cabaret about depression and bipolar disorder

This PhD represents my attempt to make sense of my personal experiences of depression through the form of cabaret. I first experienced depression in 2006. Previously, I had considered myself to be a happy and optimistic person. I found the experience of depression to be a shock: both in the experience itself, and also in the way it effected my own self image. These personal experiences, together with my professional history as a songwriter and cabaret performer, have been the motivating force behind the research project. This study has explored the question: What are the implications of applying principles of Michael White’s narrative therapy to the creation of a cabaret performance about depression and bipolar disorder? There is a 50 percent weighting on the creative work, the cabaret performance Mind Games, and a 50 percent weighting on the written exegesis. This research has focussed on the illustration of therapeutic principles in order to play games of truth within a cabaret performance. The research project investigates ways of telling my own story in relation to others’ stories through three re-authoring principles articulated in Michael White’s narrative therapy: externalisation, an autonomous ethic of living and rich descriptions. The personal stories presented in the cabaret were drawn from my own experiences and from interviews with individuals with depression or bipolar disorder. The cabaret focussed on the illustration of therapeutic principles, and was not focussed on therapeutic ends for myself or the interviewees. The research question has been approached through a methodology combining autoethnographic, practice-led and action research. Auto ethnographic research is characterised by close investigation of assumptions, attitudes, and beliefs. The combination of autoethnographic, practice-led, action research has allowed me to bring together personal experiences of mental illness, research into therapeutic techniques, social attitudes and public discourses about mental illness and forms of contemporary cabaret to facilitate the creation of a one-woman cabaret performance. The exegesis begins with a discussion of games of truth as informed by Michel Foucault and Michael White and self-stigma as informed by Michael White and Erving Goffman. These concepts form the basis for a discussion of my own personal experiences. White’s narrative therapy is focused on individuals re-authoring their stories, or telling their stories in different ways. White’s principles are influenced by Foucault’s notions of truth and power. Foucault’s term games of truth has been used to describe the effect of a ‘truth in flux’ that occurs through White’s re-authoring process. This study argues that cabaret is an appropriate form to represent this therapeutic process because it favours heightened performativity over realism, and showcases its ‘constructedness’ and artificiality. Thus cabaret is well suited to playing games of truth. A contextual review compares two major cabaret trends, personal cabaret and provocative cabaret, in reference to the performer’s relationship with the audience in terms of distance and intimacy. The study draws a parallel between principles of distance and intimacy in Michael White’s narrative therapy and relates these to performative terms of distance and intimacy. The creative component of this study, the cabaret Mind Games, used principles of narrative therapy to present the character ‘Jo’ playing games of truth through: externalising an aspect of her personality (externalisation); exploring different life values (an autonomous ethic of living); and enacting multiple versions of her identity (rich descriptions). This constant shifting between distance and intimacy within the cabaret created the effect of a truth in ‘constant flux’, to use one of White’s terms. There are three inter-related findings in the study. The first finding is that the application of principles of White’s narrative therapy was able to successfully combine provocative and empathetic elements within the cabaret. The second finding is that the personal agenda of addressing my own self-stigma within the project limited the effective portrayal of a ‘truth in flux’ within the cabaret. The third finding presents the view that the cabaret expressed ‘Jo’ playing games of truth in order to journey towards her own "preferred identity claim" (White 2004b) through an act of "self care" (Foucault 2005). The contribution to knowledge of this research project is the application of therapeutic principles to the creation of a cabaret performance. This process has focussed on creating a self-revelatory cabaret that questions notions of a ‘fixed truth’ through combining elements of existing cabaret forms in new ways. Two major forms in contemporary cabaret, the personal cabaret and the provocative cabaret use the performer-audience relationship in distinctive ways. Through combining elements of these two cabaret forms, I have explored ways to create a provocative cabaret focussed on the act of self-revelation.

Community psychology : panic or panacea

The growing social upheaval and intensifying tensions in South Africa have by their very nature evoked concern and panic among mental health professionals. In an attempt to alleviate the concomittant anxiety and appear to be more responsive to the majority, many psychologists have boarded the community psychology wagon to cross the great divide between the comfortable consultancy room and the masses. In assessing whether community psychology is the appropriate vehicle for crossing the rubicon, we will start with an overview of different models of community psychology focusing on their different conceptualizations of mental illness and how each model sees the role of the psychologist in the context of psycho-social change.

Alcohol and other drugs in construction

Evidence from the infrastructure and building sectors suggests issues of drugs and alcohol and its association with safety risk on construction sites. While most Australian jurisdictions have identified this as a critical safety issue, information is limited regarding the prevalence of alcohol and other drugs in the workplace and there is limited evidential guidance on how to effectively and efficiently address such an issue. A nationally consistent collaborative approach across the construction workforce - involving employers and employees; clients, unions; contractors and sub-contractors is required to engender a cultural change in the construction workforce – in a similar manner to the on-going initiative in securing a cultural change to drink-driving in our society where peer intervention and support is encouraged. A study to address these issues has three key objectives. Firstly, using the standard World Health Organisation Alcohol Use Disorders Identification Test (AUDIT), and a wide ranging set of structured interviews, a national qualitative and quantitative assessment of the use of drugs and alcohol is being undertaken. Secondly, the development of an appropriate industry policy with an adoption of an educative and rehabilitative approach is planned in consultation with employers and employees across the infrastructure and building sectors, with an aim of national adoption. Finally, an industry-specific cultural change management program will be developed through a nationally collaborative approach to reducing the risk of impaired performance on construction sites and increasing workers’ commitment to drugs and alcohol safety. The study outcomes stand to benefit not only occupational health and safety, through a greater understanding of the safety impacts of alcohol and other drugs at work, but also alcohol and drug use as a wider community health issue. This presentation will provide an analysis and discussion of the data collected in objective 1 and how the final results will inform the subsequent phases of the study.

Use of Bayesian MUNE to show differing rate of loss of motor units in subgroups of ALS

Objectives To evaluate differences among patients with different clinical features of ALS, we used our Bayesian method of motor unit number estimation (MUNE). Methods We performed serial MUNE studies on 42 subjects who fulfilled the diagnostic criteria for ALS during the course of their illness. Subjects were classified into three subgroups according to whether they had typical ALS (with upper and lower motor neurone signs) or had predominantly upper motor neurone weakness with only minor LMN signs, or predominantly lower motor neurone weakness with only minor UMN signs. In all subjects we calculated the half life of MUs, defined as the expected time for the number of MUs to halve, in one or more of the abductor digiti minimi (ADM), abductor pollicis brevis (APB) and extensor digitorum brevis (EDB) muscles. Results The mean half life of MUs was less in subjects who had typical ALS with both upper and lower motor neurone signs than in those with predominantly upper motor neurone weakness or predominantly lower motor neurone weakness. In 18 subjects we analysed the estimated size of the MUs and demonstrated the appearance of large MUs in subjects with upper or lower motor neurone predominant weakness. We found that the appearance of large MUs was correlated with the half life of MUs. Conclusions Patients with different clinical features of ALS have different rates of loss and different sizes of MUs. Significance: These findings could indicate differences in disease pathogenesis.

Floods and human health : a systematic review

Floods are the most common type of disaster globally, responsible for almost 53,000 deaths in the last decade alone (23:1 low- versus high-income countries). This review assessed recent epidemiological evidence on the impacts of floods on human health. Published articles (2004–2011) on the quantitative relationship between floods and health were systematically reviewed. 35 relevant epidemiological studies were identified. Health outcomes were categorized into short- and long-term and were found to depend on the flood characteristics and people's vulnerability. It was found that long-term health effects are currently not well understood. Mortality rates were found to increase by up to 50% in the first year post-flood. After floods, it was found there is an increased risk of disease outbreaks such as hepatitis E, gastrointestinal disease and leptospirosis, particularly in areas with poor hygiene and displaced populations. Psychological distress in survivors (prevalence 8.6% to 53% two years post-flood) can also exacerbate their physical illness. There is a need for effective policies to reduce and prevent flood-related morbidity and mortality. Such steps are contingent upon the improved understanding of potential health impacts of floods. Global trends in urbanization, burden of disease, malnutrition and maternal and child health must be better reflected in flood preparedness and mitigation programs.

Incipient neurovulnerability and neuroprotection in early psychosis : a proton spectroscopy study of the anterior hippocampus at 3Tesla

Programmed cell death (PCD) and progenitor cell generation (of glial and in some brain areas also neuronal fate) in the CNS is an active process throughout life and is generally not associated with gliosis which means that PCD can be pathologically silent. The striking discovery that progenitor cell generation (of glial and in some brain areas neuronal fate) is widespread in the adult CNS (especially the hippocampus) suggest a much more dynamic scenario than previously thought and transcends the dichotomy between neurodevelopmental and neurodegenerative models of schizophrenia and related disorders. We suggest that the regulatory processes that control the regulation of PCD and the generation of progenitor cells may be disturbed in the early phase of psychotic disorders underpinning a disconnectivity syndrom at the onset of clinically overt disorders. An ongoing 1H-MRS study of the anterior hippocampus at 3 Tesla in mostly drug-naive first-episode psychosis patients suggests no change in NAA, but significant increases in myo-inositol and lactate. The data suggests that neuronal integrity in the anterior hippocampus is still intact at the early stage of illness or mainly only functionally impaired. However the increase in lactate and myo-inositol may reflect a potential disturbance of generation and PCD of progenitor cells (of glial and in selected brain areas also neuronal fate) at the onset of psychosis. If true the use of neuroprotective agents such as lithium or eicosapentaenoic acid (which inhibit PCD and support cell generation)in the early phase of psychotic disorders may be a potent treatment avenue to explore.

Implications of lipid biology for the pathogenesis of schizophrenia

Objective: Preclinical and clinical data suggest that lipid biology is integral to brain development and neurodegeneration. Both aspects are proposed as being important in the pathogenesis of schizophrenia. The purpose of this paper is to examine the implications of lipid biology, in particular the role of essential fatty acids (EFA), for schizophrenia. Methods: Medline databases were searched from 1966 to 2001 followed by the crosschecking of references. Results: Most studies investigating lipids in schizophrenia described reduced EFA, altered glycerophospholipids and an increased activity of a calcium-independent phospholipase A2 in blood cells and in post-mortem brain tissue. Additionally, in vivo brain phosphorus-31 Magnetic Resonance Spectroscopy (31P-MRS) demonstrated lower phosphomonoesters (implying reduced membrane precursors) in first- and multi-episode patients. In contrast, phosphodiesters were elevated mainly in first-episode patients (implying increased membrane breakdown products), whereas inconclusive results were found in chronic patients. EFA supplementation trials in chronic patient populations with residual symptoms have demonstrated conflicting results. More consistent results were observed in the early and symptomatic stages of illness, especially if EFA with a high proportion of eicosapentaenoic acid was used. Conclusion: Peripheral blood cell, brain necropsy and 31P-MRS analysis reveal a disturbed lipid biology, suggesting generalized membrane alterations in schizophrenia. 31P-MRS data suggest increased membrane turnover at illness onset and persisting membrane abnormalities in established schizophrenia. Cellular processes regulating membrane lipid metabolism are potential new targets for antipsychotic drugs and might explain the mechanism of action of treatments such as eicosapentaenoic acid.

Health status and use of health services among recently arrived men with refugee backgrounds: A comparative analysis of urban and regional settlement in South-east Queensland

Approximately one-third of refugee and humanitarian entrants to Australia are adult men. Many of these men and their families settle in regional areas. Little is known about the health status of refugee men and the use of health services, and whether or not there are differences between those living in urban and regional areas. This paper reports on the cross-sectional differences in health status and use of health services among a group of 233 recently arrived refugee men living in urban and regional areas of South-east Queensland. Overall, participants reported good levels of subjective health status, moderate to good levels of well-being, and low prevalence of mental illness. Men living in urban areas were more likely to have a longstanding illness and report poorer health status than those settled in regional areas. In contrast, men living in regional areas reported poorer levels of well-being in the environment domain and were more likely to visit hospital emergency departments. Targeted health promotion programs will ensure that refugee men remain healthy and develop their full potential as members of the Australian community. Programs that facilitate refugees’ access to primary health care in regional areas may promote more appropriate use of hospital emergency departments by these communities.

Enhancing and promoting Indigenous women's wellness

The term "Social and Emotional Wellbeing" (SEWB) was coined through the noted inability of conventional psychiatric terminology when addressing Indigenous holistic connections and opposes the Anglo-Saxon terminology that often boxes "mental health" as a diagnosis, disease or illness into separate origins from that of other personal holistic existence, which in turn directly objects to Indigenous thinking and perceptions of wellbeing. Purpose: This study's aim was to explore what Indigenous Women's Social and Emotional Wellbeing is, through Indigenous perceptions, beliefs and knowledge of Indigenous women's wellbeing experiences. Methods: Data was derived from semi-structured focus groups incorporating Indigenous specific Yarning, where Aboriginal and Torres Strait Islander women who have experienced or were at risk of developing social and emotional wellness problems came together. Results: The women identified many factors underpinning social and emotional wellness and what it means for Aboriginal and Torres Strait Islander women. The major themes centred around wellness and health, autonomy, Indigenous women being heard, historical factors, support and Indigenous women's group development and continuation. Conclusion: These issues where then explored and compared to the National Aboriginal and Torres Strait Islander Women's Health Strategy Action Areas.

Alcohol and the foetus

The foetal alcohol syndrome (FAS) was first identified as a syndrome in 1973. Since then a large body of research has accumulated. The full syndrome in which heavy alcohol use in pregnancy results in growth retardation, a characteristic facial dysmorphology and brain damage will be described. FAS is the commonest preventable, known cause of intellectual handicap, however, a large proportion of people with partial foetal alcohol syndrome have an intelligence in the normal range. Those with the full syndrome and with identified and diagnosed, intellectual handicap are more likely to receive appropriate services. Those with an intelligence in the normal range, suffer from severe psycho- social disabilities resulting in homelessness, mental illness and frequently criminality. There is a larger number of people with a partial syndrome who also suffer from high rates of secondary disability including learning problems and 70% of FAS people also have ADD or ADHD...

Pandemic (H1N1) Influenza 2009 and Australian emergency departments : implications for policy, practice and pandemic preparedness

Objective: To describe the reported impact of Pandemic (H1N1) 2009 on EDs, so as to inform future pandemic policy, planning and response management. Methods: This study comprised an issue and theme analysis of publicly accessible literature, data from jurisdictional health departments, and data obtained from two electronic surveys of ED directors and ED staff. The issues identified formed the basis of policy analysis and evaluation. Results: Pandemic (H1N1) 2009 had a significant impact on EDs with presentation for patients with ‘influenza-like illness’ up to three times that of the same time in previous years. Staff reported a range of issues, including poor awareness of pandemic plans, patient and family aggression, chaotic information flow to themselves and the public, heightened stress related to increased workloads and lower levels of staffing due to illness, family care duties and redeployment of staff to flu clinics. Staff identified considerable discomfort associated with prolonged times wearing personal protective equipment. Staff believed that the care of non-flu patients was compromised during the pandemic as a result of overwork, distraction from core business and the difficulties associated with accommodating infectious patients in an environment that was not conducive. Conclusions: This paper describes the breadth of the impact of pandemics on ED operations. It identifies a need to address a range of industrial, management and procedural issues. In particular, there is a need for a single authoritative source of information, the re-engineering of EDs to accommodate infectious patients and organizational changes to enable rapid deployment of alternative sources of care.

Justice in Society

Australia has always made claims to being a just and fair society. It is a land of opportunity, where anyone can make it, and where mateship rather than class underpins social relations. Why is it, then, that our criminal justice system is host to the most disadvantaged and disenfranchised in our community? Why do certain groups of people continue to experience the worst forms of injustice in our society? And why do these injustices continue, despite numerous attempts by researchers and activists to address them? By exploring the ways in which we think about justice in the wider Australian society, this book considers these questions. As disciplines that have the most to say about justice and injustice, it analyses the contributions of political philosophy and sociology, and examines how their ideas have come to dominate discussion on issues ranging from asylum seeking to homophobic violence. By examining the shared assumptions about justice and injustice that underpin these discussions, this book also charts a course between and beyond these debates, and seeks to engage, challenge, and offer new possibilities for justice in Australian society. Relevant contemporary social issues like sex trafficking, homelessness, mental illness and Indigenous policing are examined throughout, placed in their historical, social and cultural context, and linked to local, national and global debates. Such analyses examine the broader implications of these criminological, social and legal issues for those excluded from justice in Australian society.

Patients undergoing subacute rehabilitation have accurate expectations of their health-related quality of life at discharge

Background Expectations held by patients and health professionals may affect treatment choices and participation (by both patients and health professionals) in therapeutic interventions in contemporary patient-centered healthcare environments. If patients in rehabilitation settings overestimate their discharge health-related quality of life, they may become despondent as their progress falls short of their expectations. On the other hand, underestimating their discharge health-related quality of life may lead to a lack of motivation to participate in therapies if they do not perceive likely benefit. There is a scarcity of empirical evidence evaluating whether patients' expectations of future health states are accurate. The purpose of this study is to evaluate the accuracy with which older patients admitted for subacute in-hospital rehabilitation can anticipate their discharge health-related quality of life. Methods A prospective longitudinal cohort investigation of agreement between patients' anticipated discharge health-related quality of life (as reported on the EQ-5D instrument at admission to a rehabilitation unit) and their actual self-reported health-related quality of life at the time of discharge from this unit was undertaken. The mini-mental state examination was used as an indicator of patients' cognitive ability. Results Overall, 232(85%) patients had all assessment data completed and were included in analysis. Kappa scores ranged from 0.42-0.68 across the five EQ-5D domains and two patient cognition groups. The percentage of exact correct matches within each domain ranged from 69% to 85% across domains and cognition groups. Overall 40% of participants in each cognition group correctly anticipated all of their self-reported discharge EQ-5D domain responses. Conclusions Patients admitted for subacute in-hospital rehabilitation were able to anticipate the discharge health-related quality of life on the EQ-5D instrument with a moderate level of accuracy. This finding adds to the foundational empirical work supporting joint treatment decision making and patient-centered models of care during rehabilitation following acute illness or injury. Accurate patient expectations of the impact of treatment (or disease progression) on future health-related related quality of life is likely to allow patients and health professionals to successfully target interventions to priority areas where meaningful gains can be achieved.

Impact of a government triple zero awareness campaign on emergency department patient characteristics

Objective: To evaluate the impact of a government triple zero community awareness campaign on the characteristics of patients attending an ED. Methods: A study using Emergency Department Information System data was conducted in an adult metropolitan tertiary-referral teaching hospital in Brisbane. The three outcomes measured in the 3 month post-campaign period were arrival mode, Australasian Triage Scale and departure status. These measures reflect ambulance usage, clinical urgency and illness severity, respectively. They were compared with those in the 3 month pre-campaign period. Multivariate logistic regression models were used to investigate the impacts of the campaign on each of the three outcome measures after controlling for age, sex, day and time of arrival, and daily minimum temperature. Results: There were 17 920 visits in the pre- and 17 793 visits in the post-campaign period. After the campaign, fewer patients arrived at the ED by road ambulance (odds ratio [OR] 0.90, 95% confidence interval [CI] 0.80–1.00), although the impact of the campaign on the arrival mode was only close to statistical significance (Wald χ2-test, P= 0.055); and patients were significantly less likely to have higher clinical urgency (OR 0.86, 95% CI 0.79–0.94), while more likely to be admitted (OR 1.68, 95% CI 1.38–2.05) or complete treatment in the ED (OR 1.46, 95% CI 1.23–1.73) instead of leaving without waiting to be seen. Conclusions: The campaign had no significant impact on the arrival mode of the patients. After the campaign, the illness acuity of the patients decreased, whereas the illness severity of the patients increased.
