This study investigated the effectiveness of a 2-day interprofessional student supervision training workshop by identifying participants' confidence and their learning outcomes, through their responses to a clinical supervision scenario. Methods: Four workshops were held with 112 of 142 workshop participants who consented to respond to a pre-and posttraining questionnaire investigating confidence ratings and to a Many supervisors are clinicians with poor access to training and resources to develop their education expertise

Secondary analysis of 24 h recall diet data from the Australian Health Survey (2011-2013). Nationally representative survey in Australia. Male and female Australians aged 18-84 years (n 7818). Dinner contributed the greatest proportion to total daily Na intake (33 %) and K intake (35 %). Na density was highest at lunch (380 mg/MJ) and K density highest at between-meal time eating occasions (401 mg/MJ). Between-meal time eating occasions provided 20 % of daily Na intake and 26 % of daily K intake. The major food group sources of Na were different at meal times (breads and mixed dishes) compared with between-meal times (cakes, muffins, scones, cake-type desserts). The top food group sources of K at meal times were potatoes and unprocessed meat products and dishes. Foods which contributed to Na and K intake differed a...

Apart from its nutritional importance as a bulking agent, we report additional roles of cellulose in human nutrition by limiting digestive enzyme action either by binding of enzymes on cellulose surfaces or providing a physical barrier towards the hydrolysis of entrapped macronutrients. Methods: (i) The kinetics of inhibition of alpha amylase activity against maize starch was determined varying cellulose concentration. (ii) Cotyledon cells from legumes were isolated without using solvents, acids or bases. The diffusion of enzyme inside the cell was monitored using fluorescence labelled alpha-amylase. Results: Kinetic analyses of alpha amylase hydrolysing maize starch in the presence of cellulose as an inhibitor using Dixon and Direct Linear plots showed marked inhibition of mixed type. The dissociation constant of the enzyme/cellulose complex was found to be 3 mg/mL. In isolated legume cells, fluorescent labelled enzymes accumulated at the outer periphery of cells and were absent inside the cells, suggesting both a binding and barrier role for cellulose. Upon removal of cellulosic physical barrier, e.g. by grinding, the rate of hydrolysis of starch in cells of legumes increased by almost 20 times. Conclusions: The study suggests that cellulosic materials have the potential to reduce the glycaemic responses form starchy foods either by inhibiting enzyme activity through binding or providing the physical barrier limiting the access of substrate to enzymes in plant-derived foods Funding source(s): ARC, University of Queensland.

Little is known however about whether increased CVD risk or established CVD has any influence on dietary intakes of Australian adults or children residing in the same household. This study aimed to determine whether the presence of CVD or CVD risk factors influences dietary intake of Australian adults and if the presence of an adult with increased CVD risk influences the dietary intake of a child living in the same household. Data were sourced from the 2011-2013 Australian Health Survey for: (1) adults ≥18 years with risk factors or established CVD and (2) children 2-17 years residing in the same household as adults with CVD risk factors or established CVD. Selected nutrient intakes (total fat, saturated fat plus trans fat, alpha-linolenic acid, total long chain omega 3 fatty acids, fibre and sodium) collected by repeated 24 h recalls were compared to nationa...

However, implementation has not matched aspiration partly because of a lack of practical tools and illustrative examples. This paper takes an interdisciplinary approach and presents the design and development of a practical tool: the curriculum design compass. The curriculum design compass covers four design spaces: What do students need to know about global health?; What do students need to be taught in order to develop cultural diversity awareness and intercultural competence?; How do we teach to facilitate and demonstrate intercultural learning?; and How do we bring students into contact with the wider world? The design compass was trialled with a Nutrition and Dietetics program and generalisability was confirmed with an unrelated profession. The programs studied were able to readily understand the tool and to use it to identify areas of existing good practice and areas for improvement. Therefore, it was both a review tool and a design tool enabling programs to manageably and holistically better prepare global health practitioners.

Good nutrition during this time is important to optimise their performance and prevent lifestyle diseases. Women also act as nutritional gatekeepers for their family. The dual burden of paid employment and unpaid family work may be associated with time scarcity in mothers which can impact food preparation and therefore nutritional adequacy. The aim of this study was to examine the diet of women who lived with children by comparison of hours worked. This was a secondary analysis of the Australian National Nutrition and Physical Activity Survey 2011-12. Subjects were women aged 18-65 years who resided with ≥1 child (<18 years). Women were grouped according to hours of employment: not working; working <25 h a week; and working ≥25 hours a week. Data from two 24-h dietary recalls were used to compare differences between groups in nutrient intake and proportion of ...

An action research framework was used to guide and inform inquiry. This involved four stages, each of which provided information to reach a final decision about how to progress forward. First, relevant information was collected to present to stakeholders. This included identification of acknowledged curriculum frameworks, a review of other accredited nutrition and dietetics courses in Australia, a review of Indigenous health topics at Flinders University, including liaison with the Poche Centre for Indigenous Health and Well-Being (Indigenous health teaching and research unit), and a review of BND and MND current curriculum related to Indigenous health. Second, input was sought from stakeholders. This involved a workshop with practising dietiti...

This study sought to review and moderate an assessment artefact of foodservice work integrated learning (WIL) to develop a shared understanding of one tool which may be used in a suite of evidence to demonstrate competence. Methods: The foodservice curricula and assessment artefacts were described for the foodservice program at each of four participating universities. An assessment artefact from WIL, the report, was identified as an indicator of foodservice competence common to each program. Each university provided four purposively sampled WIL reports, assessed in duplicate by two academics from other participating universities using the corresponding university assessment rubric. Collated assessment results, along with the original assessment, were presented back to assessors. A semi-structured group discussion explored variations in assessment results, factors influencing decisions, and potential changes needed for assessment documentation. Results: There was variation in assessment outcomes between independent assessors. In some instances assessors did not consistently deliver the same assessment outcome, nor rank students in sequential order of performance. This variation was less where an absolute ranking of satisfactory/ unsatisfactory was applied. The assessor discussion revealed three key concepts: importance of understanding the project scope; challenges which influence assessment decision making; importance of understanding the broader program of assessment. Conclusions: Assessment inconsistencies emphasise the importance of multiple assessors and assessment artefacts across a programmatic assessment model, and the need for a clear understanding of competence in nutrition and dietetics.
