A Pilot Study On The Impact Of Occupational Therapy Home Programming For Young Children With Cerebral Palsy, Iona Novak, Anne Cusick, Kevin Lowe

Faculty of Health and Behavioural Sciences - Papers (Archive)

Occupational therapy home programs are a common approach used to provide interventions for children with cerebral palsy, but there is little evidence to demonstrate the effectiveness of such programs. This singlegroup pretest–posttest design pilot study evaluated the impact of an occupational therapy home program implemented with 20 children who had spastic hemiplegic cerebral palsy (ages 2–7 years, mean 3.8). We measured impact using Goal Attainment Scaling (GAS), the Pediatric Evaluation of Disability Inventory (PEDI), and the Quality of Upper Extremity Skills Test (QUEST). We measured participation amount through a parent self-report log. Significant changes following intervention occured ...


Effects Of Splinting On Wrist Contracture After Stroke: A Randomized Controlled Trial, Natasha A. Lannin, Anne Cusick, Annie Mccluskey, Robert D. Herbert Jan 2007

Effects Of Splinting On Wrist Contracture After Stroke: A Randomized Controlled Trial, Natasha A. Lannin, Anne Cusick, Annie Mccluskey, Robert D. Herbert

Faculty of Health and Behavioural Sciences - Papers (Archive)

Background and Purpose—Splints are commonly applied to the wrist and hand to prevent and treat contracture after stroke. However, there have been few randomized trials of this intervention. We sought to determine whether wearing a hand splint, which positions the wrist in either a neutral or an extended position, reduces wrist contracture in adults with hemiplegia after stroke. Methods—Sixty-three adults who had experienced a stroke within the preceding 8 weeks participated. They were randomized to either a control group (routine therapy) or 1 of 2 intervention groups (routine therapy plus splint in either a neutral or an extended ...


Children's Television Sub-Standards: A Call For Significant Amendments, Bridget P. Kelly, Josephine Chau Jan 2007

Children's Television Sub-Standards: A Call For Significant Amendments, Bridget P. Kelly, Josephine Chau

Faculty of Health and Behavioural Sciences - Papers (Archive)

Australia has one of the highest levels of food advertising on television in the developed world, with most advertisements being for foods that are high in fat, sugar, and/or salt. Evidence from international reviews suggests that television food advertising has an independent effect on children's food preferences and purchasing requests. While the size of this effect is indeterminate, and the evidence base is correlational and therefore inadequate for making causal inferences, there is a highly plausible link between television food advertising and overweight and obesity. It is important to examine whether current regulations protect Australian children from excessive ...


Plasminogen Binding And Activation At The Breast Cancer Cell Surface: The Integral Role Of Urokinase Activity, Gillian E. Stillfried, Darren Saunders, Marie Ranson Jan 2007

Plasminogen Binding And Activation At The Breast Cancer Cell Surface: The Integral Role Of Urokinase Activity, Gillian E. Stillfried, Darren Saunders, Marie Ranson

Faculty of Health and Behavioural Sciences - Papers (Archive)

INTRODUCTION: The regulation of extracellular proteolytic activity via the plasminogen activation system is complex, involving numerous activators, inhibitors and receptors. Previous studies on monocytic and colon cell lines suggest that plasmin pre treatment can increase plasminogen binding, allowing the active enzyme to generate binding sites for its precursor. Other studies have shown the importance of pre formed receptors such as annexin II heterotetramer. However, few studies have utilised techniques which exclusively characterise cell surface events and these mechanisms have not been investigated at the breast cancer cell surface. METHODS: We have studied plasminogen binding to MCF 7 in which uPAR ...


Patient And Professional Accuracy Of Recalled Treatment Decisions In Out-Patient Consultations, Timothy C. Skinner, Katharine D. Barnard, Susan Cradock, Tracey Parkin Jan 2007

Patient And Professional Accuracy Of Recalled Treatment Decisions In Out-Patient Consultations, Timothy C. Skinner, Katharine D. Barnard, Susan Cradock, Tracey Parkin

Faculty of Health and Behavioural Sciences - Papers (Archive)

Aims  To test the assumption that professional recall of consultation decisions is valid and more accurate than patient recall of consultation decisions.

Methods  One hundred and thirty-four consultations between diabetes specialist nurses and diabetes specialist dietitians in an adult out-patient diabetes service were audiotaped. Patients and professionals were asked to recall the treatment decisions made immediately after the consultation. Patient participants were also asked to complete the Health Care Climate Questionnaire (HCC). Recalled decisions, by patient and professional participants, were then compared with those extracted from the audio tapes, and with each other.

Results  The mean duration of consultations was ...

Cumulative evidence has indicated a critical role of poly(ADP-ribose) polymerase-1 activation in ischemic brain damage. Poly(ADP-ribose) glycohydrolase (PARG) is a key enzyme in poly(ADP-ribose) catabolism. Our previous studies showed that PARG inhibitors, gallotannin (GT) and nobotanin B, can profoundly decrease oxidative cell death in vitro. Here, we tested the hypothesis that intranasal delivery of GT can decrease ischemic brain damage by inhibiting PARG. Intranasal delivery of GT within 5 hours after the onset of focal brain ischemia markedly decreased the infarct formation and neurological deficits of rats. The GT administration also increased poly(ADP-ribose) in the ischemic ...

Faculty of Health and Behavioural Sciences - Papers (Archive)

Objective: Mental health services in Australia are increasingly becoming recovery orientated. However, there are varying meanings for recovery and few measures that specifically target recovery outcomes. The current study aimed to assess the construct and concurrent validity of a patient self-report measure, the Recovery Assessment Scale (RAS).

Method: Participants were 168 individuals with severe and persistent psychiatric disability who were participants in the Australian Integrated Mental Health Initiative (AIMhi) project. They completed self-report recovery and other mental health measures and their case workers completed the Health of the Nation Outcome Scales. Exploratory and confirmatory factor analyses were carried out to ...

Non-Advertising Alcohol Promotions In Licensed Premises: Does The Code Of Practice Ensure Responsible Promotion Of Alcohol?, Sandra C. Jones, Melissa Lynch Jan 2007

Non-Advertising Alcohol Promotions In Licensed Premises: Does The Code Of Practice Ensure Responsible Promotion Of Alcohol?, Sandra C. Jones, Melissa Lynch

Faculty of Health and Behavioural Sciences - Papers (Archive)

Introduction and Aims. Binge drinking is a major public health issue in Australia, particularly among young people. There has been a considerable focus on alcohol advertising, among both researchers and policy makers, resulting in efforts to bring about some level of regulation of unacceptable advertising practices. However - despite the existence of a Code of Practice for Responsible Promotion of Liquor Products which provides 'a framework of practices which are considered acceptable and reasonable' for licensed premises - there are few, if any, data on the nature and extent of promotions which could arguably fall under either 'acceptable' or 'unacceptable' practices. Design ...

Two High-Amylose Maize Starches With Different Amounts Of Resistant Starch Vary In Their Effects On Fermentation, Tissue And Digesta Mass Accretion, And Bacterial Populations In The Large Bowel Of Pigs, Anthony R. Bird, Michelle Vuaran, Ian L. Brown, David L. Topping

Faculty of Health and Behavioural Sciences - Papers (Archive)

Four groups of young pigs (n 6) were fed a diet containing 50 % maize starch as either a highly digestible waxy starch (control; 0 % amylose) or one of three resistant starch (RS) diets, namely a high-amylose maize starch (HAMS; 85 % amylose), this starch subjected to hydrothermal treatment (HTHAMS; 85 % amylose), or a blend of HAMS and HTHAMS included in equal amounts, for 21 d. Food intake and live weight at the end of the study were similar among the four groups. Ileal starch digestibility was lower in pigs fed the three RS diets but was greater for HAMS (88 %) than ...

Things Are Looking Up: Differential Decline In Face Recognition Following Pitch And Yaw Rotation, Simone K. Favelle, Stephen A. Palmisano, Ryan T. Maloney Jan 2007

Things Are Looking Up: Differential Decline In Face Recognition Following Pitch And Yaw Rotation, Simone K. Favelle, Stephen A. Palmisano, Ryan T. Maloney

Faculty of Health and Behavioural Sciences - Papers (Archive)

Previous research into the effects of viewpoint change on face recognition has typically dealt with rotations around the heads vertical axis (yaw). Another common, although less studied, source of viewpoint variation in faces is rotation around the heads horizontal pitch axis (pitch). In the current study we used both a sequential matching task and an old/new recognition task to examine the effect of viewpoint change following rotation about both pitch and yaw axes on human face recognition. The results of both tasks showed that recognition performance was better for faces rotated about yaw compared to pitch. Further, recognition performance ...

The Role Of Achievement Goal Orientation In The Development Of Self Efficacy During Computer Training, Anura Rohan Jayasuriya, Peter Caputi, Parri Gregory, Joseph A. Meloche

Faculty of Health and Behavioural Sciences - Papers (Archive)

Computer self-efficacy (CSE) is a key factor that is related to performance in computer training. A study was conducted to understand the effects of achievement goal orientation on computer self efficacy development with 166 trainees using a database application. Results show that trainees with different achievement motivation dispositions have affects on CSE development through different paths. Individuals with high mastery approach and performance approach dispositions have positive effects on pre training CSE. Mastery avoidance disposition increases Computer Anxiety (CA), this is not seen with performance avoidance. Performance approach affects CSE development by increasing effort. The study provides initial evidence for ...

Differences In Membrane Acyl Phospholipid Composition Between An Endothermic Mammal And An Ectothermic Reptile Are Not Limited To Any Phospholipid Class, Stephen J. Blanksby, Todd W. Mitchell, Anthony J. Hulbert, Paul Else, K Ekroos

Faculty of Health and Behavioural Sciences - Papers (Archive)

This study examined questions concerning differences in the acyl composition of membrane phospholipids that have been linked to the faster rates of metabolic processes in endotherms versus ectotherms. In liver, kidney, heart and brain of the ectothermic reptile, Trachydosaurus rugosus, and the endothermic mammal, Rattus norvegicus, previous findings of fewer unsaturates but a greater unsaturation index (UI) in membranes of the mammal versus those of the reptile were confirmed. Moreover, the study showed that the distribution of phospholipid head-group classes was similar in the same tissues of the reptile and mammal and that the differences in acyl composition were present ...

'If Only...': Counterfactual Thinking Heightens Women's Sense Of Responsibility Regarding Mammography Screening, Amy Y. Chan, Sandra C. Jones, Karen T. Rich

Faculty of Health and Behavioural Sciences - Papers (Archive)

The present study tested the prediction that counterfactual thinking (thoughts of if only&) provides a vivid means for women to imagine whatcould have been done differently in hypothetical breast cancer scenarios for the protagonist to avoid their predicament.This should then encourage themto adopt a more preventative approach to and take greater personal responsibility toward their own breast health.Women aged 50 and older (N=181) read either a standard pamphlet on mammography rescreening or one containing counterfactually framed scenarios.The latter depicted fictitiouswomen whose failure to have routine mammograms contributed to their diagnosis with advance-stage breast cancer.The counterfactual ...


The Cultural Context Of Youth Suicide In Australia: Unemployment, Identity And Gender, Heidi E. Gilchrist, Glennys Howarth, Gerard Sullivan Jan 2007

The Cultural Context Of Youth Suicide In Australia: Unemployment, Identity And Gender, Heidi E. Gilchrist, Glennys Howarth, Gerard Sullivan

Faculty of Health and Behavioural Sciences - Papers (Archive)

This article considers the impact, in terms of life and death choices, of the economicexclusion of young people in Australia, where suicide is the leading cause of deathby injury. In the two decades from 1980 there was a dramatic increase in suiciderates for young males. Research demonstrates a correlation between youth suicideand unemployment but the complex relationship between the two has not been fullyinvestigated. This article explores the perceptions of young people, parents and serviceproviders of the cultural context of suicide and how it comes to be constructed as anoption for young people experiencing economic marginalisation.I n


Event-Related Potentials During An Emotional Stroop Task, Susan J. Thomas, Stuart J. Johnstone, Craig J. Gonsalvez Jan 2007

Event-Related Potentials During An Emotional Stroop Task, Susan J. Thomas, Stuart J. Johnstone, Craig J. Gonsalvez

Faculty of Health and Behavioural Sciences - Papers (Archive)

Emotional Stroop tasks have gained wide interest in scientific literature in the last two decades. Although no direct measure of attention is employed, these studies infer the presence of preferential processing of threatening information based on reaction time (RT) impairment in a competing task. Because event-related potential (ERP) measures are sensitive to both the extent (amplitude) and speed (latency) of cerebral processing, they are valuable tools with which to examine more directly the claim that threatening stimuli are associated with enhanced attention. Twenty-two students rated a pool of words to identify those that were personally disturbing. Two word types (threat ...


Arousal And Activation Effects On Physiological And Behavioral Responding During A Continuous Performance Task, Jacqueline A. Rushby, Robert J. Barry, Adam R. Clarke, Mohammad Vaezmousavi Jan 2007

Arousal And Activation Effects On Physiological And Behavioral Responding During A Continuous Performance Task, Jacqueline A. Rushby, Robert J. Barry, Adam R. Clarke, Mohammad Vaezmousavi

Faculty of Health and Behavioural Sciences - Papers (Archive)

Based on previous work indicating different neural substrates, two aspects of energetic state, arousal and activation, have been conceptualised separately in our laboratory. Arousal has been defined as the energetic state at any particular time, and task-related activation as the task-related change in state from resting baseline to the task situation. Both are reflected in electrodermal activity and measured by skin conductance level. Our previous studies in this area have indicated that physiological responses to stimuli in a task are dependent on the arousal level at the time of stimulus presentation, rather than the task-related activation. In contrast, performance on ...


A Structural Basis For Differential Cell Signalling By Pai-1 And Pai-2 In Breast Cancer Cells, Marie Ranson, David Croucher, Darren Saunders, Gillian E. Stillfried Jan 2007

A Structural Basis For Differential Cell Signalling By Pai-1 And Pai-2 In Breast Cancer Cells, Marie Ranson, David Croucher, Darren Saunders, Gillian E. Stillfried

Faculty of Health and Behavioural Sciences - Papers (Archive)

PAI-1 and PAI-2 (plasminogen-activator inibitor types 1 and 2) are inhibitors of cell surface uPA (urokinase plasminogen activator). However, tumour expression of PAI-1 and PAI-2 correlates with poor compared with good patient prognosis in breast cancer respectively. This biological divergence may be related to additional functional roles of PAI-1. For example, the inhibition of uPA by PAI-1 reveals a cryptic high-affinity site within the PAI-1 moiety for the VLDLr (very-low-density-lipoprotein receptor), which sustains cell signalling events initiated by binding of uPA to its receptor. These interactions and subsequent signalling events promote proliferation of breast cancer cells. Biochemical and structural analyses ...

Intergenerational Family Communication About Mammography: Young Women's Perceptions, Intentions And Experiences, Jessica Browne, Amy Y. Chan

Faculty of Health and Behavioural Sciences - Papers (Archive)

Early detection of breast cancer through regular mammograms is crucial to reducing the mortality rate, yet almost 50% of target women (aged 50-69years) fail to have regular mammograms. Young women aged 18-39 years (N = 60) participated in a two-stage study that explored familycommunication as a vehicle for mammography promotion to target women.Intention to initiate such a conversation was measured and predicted using the Theory of Planned Behaviour (TPB) framework.The TPB variables together produced a model that predicted behavioural performance, withintention being the only independent predictor.Young womens anticipatory perceptions and actual experiences of initiating a conversationabout mammography were ...


Attention To Configural Information In Change Detection For Faces, Simone K. Favelle, Darren Burke Jan 2007

Attention To Configural Information In Change Detection For Faces, Simone K. Favelle, Darren Burke

Faculty of Health and Behavioural Sciences - Papers (Archive)

In recent research the change-detection paradigm has been used along with cueing manipulations to show that more attention is allocated to the upper than lower facial region, and that this attentional allocation is disrupted by inversion. We report two experiments the object of which was to investigate how the type of information changed might be a factor in these findings by explicitly comparing the role of attention in detecting change to information thought to be special to faces (second-order relations) with information that is more useful for basic-level object discrimination (first-order relations). Results suggest that attention is automatically directed to ...

What To Ask In A Self-Administered Dietary Assessment Website: The Role Of Professional Judgement, Y. C. Probst, Linda C. Tapsell

Faculty of Health and Behavioural Sciences - Papers (Archive)

Background: Professional judgement is a key component of questionnaire development, subjective in nature and rarely reported in this context. It is required in dietary questionnaires to delimit the size whilst retaining quality of the data.
Objectives: To describe the nature and extent of professional judgement involved in developing a food database to include in a web-based self-administered dietary assessment.
Methods & materials: Professional judgement was applied in tandem with a stepwise statistical analysis of hierarchically reported foods in the Australian National Nutrition Survey (NNS95). Statistical analyses determined foods commonly consumed and eaten together and three different forms of cluster analysis were ...
