Heavy cannabis abuse increases the risk of developing schizophrenia. Adolescents appear particularly vulnerable to the development of psychosis-like symptoms after cannabis use. To test whether the schizophrenia candidate gene neuregulin 1 (NRG1) modulates the effects of cannabinoids in adolescence, we tested male adolescent heterozygous transmembrane domain Nrg1 mutant (Nrg1 TM HET) mice and wild type-like littermates (WT) for their neurobehavioural response to repeated Δ9-tetrahydrocannabinol (THC, 10 mg/kg i.p. for 21 d starting on post-natal day 31). During treatment and 48 h after treatment withdrawal, we assessed several behavioural parameters relevant to schizophrenia. After behavioural testing we ...


Musculoskeletal And Estrogen Changes During The Adolescent Growth Spurt In Girls, Catherine Y. Wild, Julie R. Steele, Bridget J. Munro Jan 2013

Musculoskeletal And Estrogen Changes During The Adolescent Growth Spurt In Girls, Catherine Y. Wild, Julie R. Steele, Bridget J. Munro

Faculty of Health and Behavioural Sciences - Papers (Archive)

Introduction: The adolescent growth spurt is associated with rapid growth and hormonal changes, thought to contribute to the increased anterior cruciate ligament injury risk in girls. However, relatively little is known about these musculoskeletal and estrogen changes during the growth spurt in girls. Purpose: To investigate the longitudinal changes in estrogen as well as anterior knee laxity and lower limb strength and flexibility throughout the adolescent growth spurt in girls. Methods: Thirty-three healthy girls, age 10-13 yr, in Tanner stage II and 4-6 months from their peak height velocity were recruited. Participants were tested up to four times during the ...

Direct Evidence For Encoding Of Motion Streaks In Human Visual Cortex, Deborah M. Apthorp, D. Samuel Schwarzkopf, C. Kaul, B. Bahrami, David Alais, G. Rees

Temporal integration in the visual system causes fast-moving objects to generate static, oriented traces (‘motion streaks’), which could be used to help judge direction of motion. While human psychophysics and single-unit studies in non-human primates are consistent with this hypothesis, direct neural evidence from the human cortex is still lacking. First, we provide psychophysical evidence that faster and slower motions are processed by distinct neural mechanisms: faster motion raised human perceptual thresholds for static orientations parallel to the direction of motion, whereas slower motion raised thresholds for orthogonal orientations. We then used functional magnetic resonance imaging to measure brain activity ...


Evaluation Of The Evidence Between Consumption Of Refined Grains And Health Outcomes, Peter G. Williams Feb 2012

Evaluation Of The Evidence Between Consumption Of Refined Grains And Health Outcomes, Peter G. Williams

Faculty of Health and Behavioural Sciences - Papers (Archive)

This review evaluates the available evidence on the relationship between consumption of refined grains and health outcomes. A total of 135 relevant articles were identified from database searches of studies published between 2000 and 2010. The great majority found no associations between the intake of refined grain foods and cardiovascular disease, diabetes, weight gain or overall mortality. A few studies found that very high intakes might be associated with some types of cancers, but at moderate levels of consumption the risks were not significant. The totality of evidence shows that consumption of up to 50% of all grain foods as ...

Deviance And Diversity In Dietetics, Peter Williams Jan 2012

Deviance And Diversity In Dietetics, Peter Williams

Faculty of Health and Behavioural Sciences - Papers (Archive)

Like all professions, dietetics is concerned with the definition, teaching and assessment of professional behaviour (Gingras, 2009; Arnold, 2002), and while diversity may be welcomed, there are limits to what is regarded as acceptable differences in professional practice. There is a dark side: when difference becomes deviance. The deviance of health professionals may seem particularly damaging, because their clients hold them in positions of trust and tend to be unable to question the professional’s judgement (Gauthier, 2001). A dietitian promising to cure cancer with vitamin supplements would be regarded as deviating from the bounds of professionally acceptable behaviour.

Faculty of Health and Behavioural Sciences - Papers (Archive)

While the profiling of subtypes of Attention Deficit Hyperactivity Disorder (AD/HD) have been the subject of considerable scrutiny, both psychometrically and psychophysiologically, little attention has been paid to the effect of diagnoses comorbid with AD/HD on such profiles. This is despite the greater than 80% prevalence of comorbidity under the DSM-IV-TR diagnostic definitions. Here we investigate the event related potential (ERP) and psychometric profiles of Controls, AD/HD, and comorbid AD/HD (particularly AD/HD+ODD/CD) groups on six neurocognitive tasks thought to probe the constructs of selective and sustained attention, response inhibition and executive function. Data ...

Faculty of Health and Behavioural Sciences - Papers (Archive)

Increasing vegetable consumption is part of dietary advice for weight loss, but how this converts to vegetable choices is not known. In this context, our aim was to identify the main vegetable groups reported by the study sample in the Healthy Eating and Lifestyle Trial [ACTRN1260000784011] at baseline (Oct 2010-Feb 2011) and after 3mo (Feb - May 2011). Data from diet histories (DH) were analyzed using the AUSNUT 2007 database in Foodworks (Xyris, version 6.0.2562) to determine the average daily amount (g) of vegetables consumed by the study sample. Baseline DH (n=113 subjects; 85 female) exposed 32 vegetable ...


A Patient Experiencing Pseudoseizures: A Case Report, F Joseph, J Quinlan Jan 2012

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

The long-term effect of regular cannabis use on brain function underlying cognitive control remains equivocal. Cognitive control abilities are thought to have a major role in everyday functioning, and their dysfunction has been implicated in the maintenance of maladaptive drug-taking patterns. In this study, the Multi-Source Interference Task was employed alongside functional magnetic resonance imaging and psychophysiological interaction methods to investigate functional interactions between brain regions underlying cognitive control. Current cannabis users with a history of greater than 10 years of daily or near-daily cannabis smoking (n=21) were compared with age, gender, and IQ-matched non-using controls (n=21). No ...

Obesity and excessive lipolysis are implicated in preeclampsia (PE). Intrauterine growth restriction is associated with low maternal body mass index and decreased lipolysis. Our aim was to assess how maternal and offspring fatty acid metabolism is altered in mothers in the third trimester of pregnancy with PE (n=62) or intrauterine growth restriction (n=23) compared with healthy pregnancies (n=164). Markers of lipid metabolism and erythrocyte fatty acid concentrations were measured. Maternal adipose tissue fatty acid composition and mRNA expression of adipose tissue fatty acid–metabolizing enzymes and placental fatty acid transporters were compared. Mothers with PE had higher ...

In humans, the integrated response to a novel stimulus (orienting reflex, OR) includes behavioral (head turning etc.) and well-characterized physiological components (changes in heart rate, respiration, skin conductance, and EEG patterns). In rodents, the physiological components of the OR include changes in heart rate and cutaneous vasoconstrictor tone, but respiratory changes have so far not been systematically documented. In the present study conducted in adult male Wistar rats, the OR was elicited by 60-dB acoustic tones while animals were in a whole-body plethysmograph for respiratory recordings. In addition to respiration, in different groups of animals we concurrently recorded either EEG ...

Hunger Enhances Vertical Vection, Takeharu Seno, Hiroyuki Ito, Shoji Sunaga, Stephen Palmisano Jan 2012

Hunger Enhances Vertical Vection, Takeharu Seno, Hiroyuki Ito, Shoji Sunaga, Stephen Palmisano

Faculty of Health and Behavioural Sciences - Papers (Archive)

Hunger was found to facilitate visually induced illusory upward and downward self-motions (vertical vection), but not illusory self-motion in depth (vection in depth). We propose that the origin of this hunger effect lies in the possibility that vertical self-motions (both real and illusory) are more likely to induce changes in visceral state.

Data available from a total of n=118 volunteers recruited to the dietary trial and using the website in the clinic at t=0, 3 and 12mo was compared with that obtained from diet histories (DH) and 3-day food record (FR). Fasting blood samples from these time points were also correlated with the macronutrient values obtained. Complete web based records were obtained for 65% of participants at t=0 ...


Simulated Angular Head Oscillation Enhances Vection In Depth, Juno Kim, Stephen Palmisano, Frederick Bonato Jan 2012

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 ...

Barriers And Enablers To Implementation Of A New Zealand-Wide Guideline For Assessment And Management Of Cardiovascular Risk In Primary Health Care: A Template Analysis, Ann Mckillop, Jackie Crisp, Kenneth Walsh

Faculty of Health and Behavioural Sciences - Papers (Archive)

Aim: The aim of this study was to identify the enablers and barriers to guideline implementation in a primary healthcare setting by employing the Promoting Action on Research Implementation in Health Services (PARIHS) framework as a template for data analysis and interpretation. Background: The use of clinical practice guidelines is pivotal to improving health outcomes. However, the implementation of guidelines into practice is complex, unpredictable, and, in spite of much investigation, remains resistant to explanation of what works and why. Optimising the enablers and minimising the barriers to implementation of a guideline for reducing cardiovascular disease risk has the potential ...

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 ...

Faculty of Health and Behavioural Sciences - Papers (Archive)

Purpose - The purpose of this study is to develop a new measure called the Career Pathways Survey (CPS) which allows quantitative comparisons of women's beliefs about glass ceilings. Design/methodology/approach - A 34-item version of the CPS was completed by 243 women from all levels of management, mostly in Australia. An expanded 38-item CPS was administered to another sample of women (N = 307). Findings - Analyses of data from both studies yielded a four factor model of attitudes to glass ceilings: resilience, acceptance, resignation and denial. The factors demonstrated good internal consistency. Practical implications - The CPS allows a comparison of ...


Use Of Day Centers For Respite By Help-Seeking Caregivers Of Individuals With Dementia, Lyn Phillipson, Sandra C. Jones Jan 2012

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 or ...

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 ...

"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 ...
