The Link Between Dietary Glycemic Index And Nutrient Adequacy, Jimmy Chun Yu Louie, Annette E. Buyken, Jennie C. Brand-Miller, Victoria M. Flood

Faculty of Health and Behavioural Sciences - Papers (Archive)

BACKGROUND: Low-glycemic index (low-GI) diets may be less nutritious because of limited food choices. Alternately, high-GI diets could be less healthful because of a higher intake of refined carbohydrate. OBJECTIVE: The objective was to investigate the association between dietary GI, intakes of carbohydrates from high-GI (CHO(high GI)) and low-GI (CHO(low GI)) sources, and the risk of nutrient inadequacy in children and adolescents. DESIGN: Children, aged 2-16 y, who provided 2 plausible 24-h recalls in a national survey were included (n = 4140). The ORs of not meeting the Australian Nutrient Reference Values (NRVs) were calculated by logistic regression. RESULTS: Subjects …

Use Of Day Centers For Respite By Help-Seeking Caregivers Of Individuals With Dementia, Lyn Phillipson, Sandra C. Jones

Faculty of Health and Behavioural Sciences - Papers (Archive)

Addressing the under utilisation of respite services in caregivers of people with dementia is an important task to improve social support amongst this vulnerable group. This paper utilises theory to conceptualise the behavioural, normative and control beliefs that caregivers of people with dementia associate with the use of out of home day centers for respite. Interviews and focus groups with 36 caregivers were undertaken to explore the beliefs of both users and non-users of services. Whilst service users held positive beliefs, non - users perceived negative outcomes for the care recipient with dementia, or faced barriers associated with their behavioural …

Using The Theory Of Planned Behaviour And Implementation Intentions To Predict And Facilitate Upward Family Communication About Mammography, J L. Browne, A Y. C Chan

Faculty of Health and Behavioural Sciences - Papers (Archive)

Regular mammography facilitates early detection of breast cancer, and thus increases the chances of survival from this disease. Daughter-initiated (i.e. upward) communication about mammography within mother– daughter dyads may promote mammography to women of screening age. The current study examined this communication behaviour within the context of the Theory of Planned Behaviour (TPB), and aimed to bridge the intention-behaviour gap by trialling an implementation intention (II) intervention that aimed to facilitate upward family communication about mammography. Young women aged 18–39 (N¼116) were assigned to either a control or experimental condition, and the latter group formed IIs about initiating a conversation …

Perinatal Phencyclidine Treatment Alters Neuregulin 1/Erbb4 Expression And Activation In Later Life, Teresa M. Du Bois, Kelly Anne Newell, Xu-Feng Huang

Faculty of Health and Behavioural Sciences - Papers (Archive)

Schizophrenia is a complex and devastating mental disorder of unknown etiology. Hypofunction of N-methyl-d-aspartate (NMDA) receptors are implicated in the disorder, since phencyclidine (PCP) and other NMDA receptor antagonists mimic schizophrenia-like symptoms in humans and animals so well. Moreover, genetic linkage and post mortem studies strongly suggest a role for altered neuregulin 1 (Nrg1)/erbB4 signaling in schizophrenia pathology. This study investigated the relationship between the NMDA receptor and Nrg1 signaling pathways using the perinatal PCP animal model. Rats (n = 5/group) were treated with PCP (10 mg/kg) or saline on postnatal days (PN) 7, 9 and 11 and were sacrificed …

Faculty of Health and Behavioural Sciences - Papers (Archive)

BACKGROUND: The purpose of this study was to describe the food and nutrient intake of a population of rural Australian children particularly Indigenous children. Participants were aged 10 to 12 years, and living in areas of relative socio-economic disadvantage on the north coast of New South Wales. METHODS: In this descriptive cross-sectional study 215 children with a mean age of 11.30 (SD 0.04) years (including 82 Indigenous children and 93 boys) completed three 24-hour food recalls (including 1 weekend day), over an average of two weeks in the Australian summer of late 2005. RESULTS: A high proportion of children consumed …

Simulated Angular Head Oscillation Enhances Vection In Depth, Juno Kim, Stephen Palmisano, Frederick Bonato

Faculty of Health and Behavioural Sciences - Papers (Archive)

Research has shown that adding simulated linear head oscillation to radial optic flow displays enhances the illusion of self-motion in depth (ie linear vection). We examined whether this oscillation advantage for vection was due to either the added motion parallax or retinal slip generated by insufficient compensatory eye movement during display oscillation. We constructed radial flow displays which simulated 1 Hz horizontal linear head oscillation (generates motion parallax) or angular head oscillation in yaw (generates no motion parallax).We found that adding simulated angular or linear head oscillation to radial flow increased the strength of linear vection in depth. Neither type …

Influence Of 18ghz Microwave Radiation On The Enzymatic Activity Of Escherichia Coli Lactate Dehydrogenase And Cytochrome C Oxidase, Yuri Shamis, Alex Traub, Rodney J. Croft, Russell Crawford, Elena Ivanova

Faculty of Health and Behavioural Sciences - Papers (Archive)

The catalytic activity of two common bacterial enzymes, lactate dehydrogenase (LDH) and cytochrome c oxidase (COX) from Escherichia coli, was examined following bacterial exposure to microwave (MW) radiation under well-defined experimental conditions. The experiments were conducted in a specialised microwave processing apparatus, with an exposure frequency of 18 GHz, and a temperature profile that was restricted to below 40oC to avoid thermal degradation of the bacteria. The absorbed power was calculated to be 1500 kW/m3 and the electric field was determined to be 300 V/m. Both values were theoretically confirmed using Computer Simulation Technology (CST) Microwave Studio 3D Electromagnetic Stimulation …

The Comparison Of The Effect Of Oat And Shiitake Mushroom Powder To Prevent Body Weight Gain In Rats Fed High Fat Diet, Dian Handayani, Barbara J. Meyer, Jiezhong Chen, Patricia Tang, Philip Chi Lip Kwok, Hak-Kim Chan, Xu-Feng Huang

Faculty of Health and Behavioural Sciences - Papers (Archive)

Preventing obesity could be done by lowering plasma TAG that inhibits adipogenesis. Oat and mushroom beta-glucans in the diet has been reported to lower plasma lipid; however the data focusing on their effects on TAG and obesity are insufficient. In the present study, lowering plasma triacylglycerol, fat deposition, body weight gain (BWG) in rats fed a high fat diet (HFD) was evaluated. Rats in the control group were given HFD only and rats in the treatment group fed HFD enriched with 0.2%, 0.6% and 1.8% (wt:wt) beta-glucan from oats (LD-O, MD-O, HD-O) or mushroom (LD-M, MD-M, HD-M). After 6 weeks …

Group Cohesion And Homework Adherence In Multi-Family Group Therapy For Schizophrenia, Frank P. Deane, Joanne Mercer, Anahita Talyarkhan, Gordon Lambert, Judy Pickard

Faculty of Health and Behavioural Sciences - Papers (Archive)

This study examined the relationship between levels of group cohesion, defined as whole group relationships, and between-session therapeutic homework adherence in a multi-family group therapy (MFGT) for people with schizophrenia. Participants from 18 consenting families attending MFGT groups completed weekly homework adherence ratings, group cohesion and spontaneous between-session activity measures. Levels of group cohesion at each session were compared with measures of scheduled and spontaneous homework adherence reported at the next session. It was hypothesised that higher levels of group cohesion would be related to homework adherence and other spontaneous between-session therapeutic activity completed by group members. Results show higher …

Study Protocol: A Randomized Controlled Trial Of A Computer-Based Depression And Substance Abuse Intervention For People Attending Residential Substance Abuse Treatment, Peter J. Kelly, Frances Kay-Lambkin, Amanda Baker, Frank P. Deane, Adam C. Brooks, Alexandra Mitchell, Sarah Marshall, Meredith Whittington, Genevieve A. Dingle

Faculty of Health and Behavioural Sciences - Papers (Archive)

"Background: A large proportion of people attending residential alcohol and other substance abuse treatment have a co-occurring mental illness. Empirical evidence suggests that it is important to treat both the substance abuse problem and co-occurring mental illness concurrently and in an integrated fashion. However, the majority of residential alcohol and other substance abuse services do not address mental illness in a systematic way. It is likely that computer delivered interventions could improve the ability of substance abuse services to address co-occurring mental illness. This protocol describes a study in which we will assess the effectiveness of adding a computer delivered …

Vection Can Be Induced Without Global-Motion Awareness, Takeharu Seno, Stephen A. Palmisano, Hiroyuki Ito, Shoji Sunaga

Faculty of Health and Behavioural Sciences - Papers (Archive)

A new vection illusion is reported. Vection was induced even though there was no consciously perceived global display motion corresponding to the self-motion. The resulting experience can be summarised as: ``I feel that I am moving but I do not know why''.

Cannabis use is highly prevalent among people with schizophrenia, and coupled with impaired cognition, is thought to heighten the risk of illness onset. However, while heavy cannabis use has been associated with cognitive deficits in long-term users, studies among patients with schizophrenia have been contradictory. This article consists of 2 studies. In Study I, a meta-analysis of 10 studies comprising 572 patients with established schizophrenia (with and without comorbid cannabis use) was conducted. Patients with a history of cannabis use were found to have superior neuropsychological functioning. This finding was largely driven by studies that included patients with a lifetime …

Do We Provide Meaningful Guidance For Healthy Eating? An Investigation Into Consumers' Interpretation Of Frequency Consumption Terms, Lesley King, Wendy L. Watson, Kathy Chapman, Bridget Kelly, Jimmy Chun Yu Louie, Clare Hughes, Jennifer Crawford, Timothy P. Gill

Faculty of Health and Behavioural Sciences - Papers (Archive)

OBJECTIVE: To investigate consumers' understanding of terms commonly used to provide guidance about frequency and quantity of food consumption. METHODS: A survey of 405 shoppers explored how frequently consumers thought food labeled with the terms "eat often," "eat moderately," "eat occasionally," "a sometimes food," and "an extra food" should be eaten. In a separate phase, 30 grocery buyers responded to open-ended questions about their interpretation of these terms. RESULTS: Responses indicated significant differences in meaning between the terms. However, the specific interpretation of each term varied considerably across respondents. The qualitative research found the terms to be highly subjective, and …

Role Of Abca7 In Mouse Behaviours Relevant To Neurodegenerative Diseases, Warren Logge, David Cheng, Rose Chesworth, Surabhi Bhatia, Brett Garner, Woojin Scott Kim, Tim Karl

Faculty of Health and Behavioural Sciences - Papers (Archive)

ATP-binding cassette transporters of the subfamily A (ABCA) are responsible for the translocation of lipids including cholesterol, which is crucial for neurological function. Recent studies suggest that the ABC transporter ABCA7 may play a role in the development of brain disorders such as schizophrenia and Alzheimer's disease. However, Abca7's role in cognition and other behaviours has not been investigated. Therefore, we characterised homozygous Abca7 knockout mice in a battery of tests for baseline behaviours (i.e. physical exam, baseline locomotion and anxiety) and behaviours relevant to schizophrenia (i.e. prepulse inhibition and locomotor response to psychotropic drugs) and Alzheimer's disease (i.e. cognitive …

A Patient Experiencing Pseudoseizures: A Case Report, F Joseph, J Quinlan

Faculty of Health and Behavioural Sciences - Papers (Archive)

Pseudoseizures are a relatively complex problem of unknown aetiology and prognosis. They can at times resemble genuine seizure attacks but they have no abnormal electroencephalograpic (EEG) activity. Understanding the patient's unique psychological background appears to be fundamental in managing seizure frequency. Pseudoseizures can be disruptive to a person's lifestyle, limiting their ability to function and progress in society, particularly when it comes to employment or social interaction. The case discussed involves a 59-year old man who presents with what is believed to be seizurerelated activity but through the course of clinical evaluation, this turned out to be pseudoseizures

In girls, after adjusting for age, ethnicity, parental education, parental history of hypertension, baseline height, baseline blood pressure, …

An Indoor Localisation And Motion Monitoring System To Determine Behavioural Activity In Dementia Afflicted Patients In Aged Care, Matthew D'Souza, Montserrat Ros, Mohanraj Karunanithi

Faculty of Health and Behavioural Sciences - Papers (Archive)

Dementia is highly prevalent among the older population. Most patients with dementia are admitted to an aged care facility due to wandering behaviour which tends to result in dangerous scenarios such as straying away from the facility and being seriously injured. Due to the decreasing availability of carers in aged care, there is a need to prioritise monitoring of patients that have a severe case of wondering. The challenge is to allow carers to monitor the status of such patients in terms of position localisation and motion behavioural status, in real-time. The long term behavioural analysis of such patients would …

Publication Bias, The File Drawer Problem, And How Innovative Publication Models Can Help, D Apthorp

Faculty of Health and Behavioural Sciences - Papers (Archive)

One of the topics that has come up frequently in the discussions on open science has been the "filedrawer problem", otherwise known as publication bias (Rosenthal, 1979 Psychological Bulletin 86(3), 638-641). Traditional publishing practices have tended to favour positive results that reject the null hypothesis, leading some researchers to suggest that, in the extreme case, "most published results are false" (Ioannidis, 2005 PLoS Medicine 2(8), e124). What does this mean for vision science, and how can an open science framework help address this problem? I will suggest that innovative publishing initiatives such as PsychFileDrawer.org and the Reproducibility Project can harness …
