ABSTRACT
BACKGROUND: Assessment presents one of the greatest challenges to evaluating health professional trainee performance, as a result of the subjectivity of judgements and variability in assessor standards. The present study aimed to test a moderation procedure for assessment across four independent universities and explore approaches to assessment and the factors that influence assessment decisions. METHODS: Assessment tasks designed independently by each of the four universities to assess student readiness for placement were chosen for the present study. Each university provided four student performance recordings for moderation. Eight different academic assessors viewed the student performances and assessed them using the corresponding university assessment instrument. Assessment results were collated and presented back to the assessors, together with the original university assessment results. Results were discussed with assessors to explore variations. The discussion was recorded, transcribed, thematically analysed and presented back to all assessors to achieve consensus on the emerging major learnings. RESULTS: Although there were differences in absolute scores, there was consistency (12 out of 16 performances) in overall judgement decisions regarding placement readiness. Proficient communication skills were considered a key factor when determining placement readiness. The discussion revealed: (i) assessment instruments; (ii) assessor factors; and (iii) the subjectivity of judgement as the major factors influencing assessment. CONCLUSIONS: Assessment moderation is a useful method for improving the quality of assessment decisions by sharing understanding and aligning standards of performance.

BACKGROUND/OBJECTIVES: Research on prisoners is limited and demonstrates a group with disproportionate numbers from disadvantaged backgrounds, known to have a high burden of disease, much of which is diet related. The aim of this study was to gauge the presence of markers of chronic disease, as a basis for food and nutrition policy in prisons. SUBJECTS/METHODS: A cross-sectional study design was used with a convenience sample of prisoners in a male 945 bed high secure facility. Face-to-face interviews with physical measures of height, weight, body fat, waist circumference and blood pressure were collected along with fasting bloods. Data were confirmed with facility records, observations and staff interviews. Full ethics approval was obtained. Results were compared with studies of Australian prisoners and the general population. RESULTS: The mean age was 35.5 years (n=120). Prevalence rates were as follows: obesity 14%, diabetes 5%, hypertension 26.7% and smoking 55.8%. Self-report of daily physical activity was 84%, with 51% participating ⩾2 times daily. Standard food provision was consistent with dietary recommendations, except that sodium was high. Where fasting bloods were obtained (n=78), dyslipidaemia was 56.4% with the metabolic syndrome (MS) present in 26%. CONCLUSIONS: Prevalence of diabetes and heart disease risk appear similar to the general population; however, obesity was lower and smoking higher. The data provide evidence that markers of chronic disease are present, with this the first study to describe the MS in prisoners. Food and nutrition policy in this setting is complex and should address the duty of care issues that exist.

BACKGROUND: Studies amongst older people with acute dysphagic stroke requiring thickened fluids have assessed fluid intakes from combinations of beverage, food, enteral and parenteral sources, but not all sources simultaneously. The present study aimed to comprehensively assess total water intake from food, beverages, enteral and parenteral sources amongst dysphagic adult in-patients receiving thickened fluids. METHODS: Patients requiring thickened fluid following dysphagia diagnosis were recruited consecutively from a tertiary teaching hospital's medical and neurosurgical wards. Fluid intake from food and beverages was assessed by wastage, direct observation and quantified from enteral and parenteral sources through clinical medical records. RESULTS: No patients achieved their calculated fluid requirements unless enteral or parenteral fluids were received. The mean daily fluid intake from food was greater than from beverages whether receiving diet alone (food: 807 +/- 363 mL, food and beverages: 370 +/- 179 mL; P < 0.001) or diet with enteral or parenteral fluid support (food: 455 +/- 408 mL, food and beverages: 263 +/- 232 mL; P < 0.001). Greater daily fluid intakes occurred when receiving enteral and parenteral fluid in addition to oral dietary intake, irrespective of age group, whether assistance was required, diagnosis and whether stage 3 or stage 2 thickened fluids were required (P < 0.05). After enteral and parenteral sources, food provided the most important contribution to daily fluid intakes. CONCLUSIONS: The greatest contribution to oral fluid intake was from food, not beverages. Designing menus and food services that promote and encourage the enjoyment of fluid dense foods, in contrast to thickened beverages, may present an important way to improve fluid intakes of those with dysphagia. Supplemental enteral or parenteral fluid may be necessary to achieve minimum calculated fluid requirements.

Randomly amplified polymorphic DNA (RAPD), successfully used to establish flower colour, is of limited importance in characterising weedy varieties of Lantana camara. Initially the internal transcribed spacer 1 (ITS1) region was sequenced for common pink and common pink-edged red varieties of L. camara from Australia and L. urticofolia from the neotropics. This proved unhelpful in differentiating varieties due to a lack of variation and the hybrid origin of L. camara, necessitating the utilisation of DNA profiling techniques. Unweighted pair group method arithmetic average (UPGMA) analysis of RAPD data demonstrated that geographical proximity contributes more significantly to genetic relatedness than flower colour. Analysis of molecular variance (AMOVA) likewise demonstrated that geography accounts for a relatively large variance component. These data indicate that the use of flower colour as a primary identification tool needs to be reevaluated. The use of RAPD may prove useful in characterising the weedy varieties of lantana present in Australia and the South Pacific. Since biological control efforts are being hindered by the inadequacy of current morphological taxonomy, it is expected that DNA profiling will underpin continuing studies on the management and control of L. camara.
