Objective To examine urban-rural differences and individual risk factors for a late stage of breast cancer at diagnosis in Australian women. Design Individual-level longitudinal data were linked with cancer registry data from New South Wales (New South Wales Cancer Registry linked by the Centre for Health Record Linkage (CHeReL)), Queensland (Queensland Cancer Registry) and Victoria (The Cancer Council Victoria). Setting Participants were drawn from the Australian Longitudinal Study on Women's Health 1946-1951 cohort (n = 13 715). Participants The sample included 195 women identified from the linked cancer registry data with a breast cancer diagnosis. Interventions Rural or urban residence was measured using Accessibility/Remoteness Index of Australia Plus (ARIA+). Individual characteristics and socio-demographic variables examined included survey year, menopausal status, country of birth, education and marital status. Main outcome measures A late stage of breast cancer at diagnosis was defined based on the TNM Classification of Malignant Tumours. Results A late stage of breast cancer diagnosis was observed in 36% of women residing in urban areas and 40% of women residing in rural areas. After adjusting for individual characteristics, we found that obesity was the strongest risk factor for a late stage of breast cancer at diagnosis. Conclusions Given that women are becoming increasingly obese, and that the rate of obesity is higher in the Australian rural population, this paper provides further evidence for targeting interventions for obesity, particularly in rural Australia, as a public health priority.

Aim This study aimed to demonstrate how supervisors and students use their time during the three domains of nutrition and dietetic clinical placement and to what extent patient-care and non-patient activities change during placement compared with pre- and post-placement. Methods A cohort survey design was used with students from two Queensland universities, and their supervisors in 2010. Participants recorded their time use in either a paper-based or an electronic survey. Supervisors' and students' time use was calculated as independent daily means according to time-use categories reported over the length of the placement. Mean daily number of occasions of service, length of occasions of service, project activities and other time use in minutes was reported as productivity output indicators and the data imputed. A linear mixed modelling approach was used to describe the relationship between the stage of placement and time use in minutes. Results Combined students' (n = 21) and supervisors' (n = 29) time use as occasions of service or length of occasions of service in patient-care activities were significantly different pre, during and post placement. On project-based placements in food-service management and community public health nutrition, supervisors' project activity time significantly decreased during placements with students undertaking more time in project activities. Conclusions This study showed students do not reduce occasions of service in patient care, and they enhance project activities in food service and community public health nutrition while on placement. A larger study is required to confirm these results. [ABSTRACT FROM AUTHOR]

Background Gut hormones change with weight loss in adults but are not well studied in obese youth. Objective The primary aim was to evaluate how gut hormones and subjective appetite measure change with dietary weight loss in obese adolescents. Methods Participants were a subset of those taking part in the 'Eat Smart Study'. They were aged 10-17 years with body mass index ( BMI) > 90th centile and were randomized to one of three groups: wait-listed control, structured reduced carbohydrate or structured low-fat dietary intervention for 12 weeks. Outcomes were fasting glucose, insulin, leptin, adiponectin, total amylin, acylated ghrelin, active glucagon-like peptide-1, glucose-dependent insulinotropic polypeptide ( GIP), pancreatic polypeptide ( PP) and total peptide tyrosine-tyrosine. Pre- and postprandial subjective sensations of appetite were assessed using visual analogue scales. Results Of 87 'Eat Smart' participants, 74 participated in this sub-study. The mean (standard deviation) BMI z-score was 2.1 (0.4) in the intervention groups at week 12 compared with 2.2 (0.4) in the control group. Fasting insulin ( P = 0.05) and leptin ( P = 0.03) levels decreased, while adiponectin levels increased ( P = 0.05) in the intervention groups compared with control. The intervention groups were not significantly different from each other. A decrease in BMI z-score at week 12 was associated with decreased fasting insulin ( P < 0.001), homeostatic model of assessment-insulin resistance ( P < 0.001), leptin ( P < 0.001), total amylin ( P = 0.03), GIP ( P = 0.01), PP ( P = 0.02) and increased adiponectin ( P < 0.001). There was no significant difference in appetite sensations. Conclusions Modest weight loss in obese adolescents leads to changes in some adipokines and gut hormones that may favour weight regain.

Background Research has identified associations between serum 25( OH) D and a range of clinical outcomes in chronic kidney disease and wider populations. The present study aimed to investigate vitamin D deficiency/insufficiency in dialysis patients and the relationship with vitamin D intake and sun exposure. Methods A cross-sectional study was used. Participants included 30 peritoneal dialysis (PD) (43.3% male; 56.87 ± 16.16 years) and 26 haemodialysis (HD) (80.8% male; 63.58 ± 15.09 years) patients attending a department of renal medicine. Explanatory variables were usual vitamin D intake from diet/supplements ( IU day−1) and sun exposure (min day−1). Vitamin D intake, sun exposure and ethnic background were assessed by questionnaire. Weight, malnutrition status and routine biochemistry were also assessed. Data were collected during usual department visits. The main outcome measure was serum 25( OH) D (n m). Results Prevalence of inadequate/insufficient vitamin D intake differed between dialysis modality, with 31% and 43% found to be insufficient (<50 n m) and 4% and 33% found to be deficient (<25 n m) in HD and PD patients, respectively ( P < 0.001). In HD patients, there was a correlation between diet and supplemental vitamin D intake and 25( OH)D (ρ = 0.84, P < 0.001) and average sun exposure and 25( OH)D (ρ = 0.50, P < 0.02). There were no associations in PD patients. The results remained significant for vitamin D intake after multiple regression, adjusting for age, gender and sun exposure. Conclusions The results highlight a strong association between vitamin D intake and 25( OH)D in HD but not PD patients, with implications for replacement recommendations. The findings indicate that, even in a sunny climate, many dialysis patients are vitamin D deficient, highlighting the need for exploration of determinants and consequences. [ABSTRACT FROM AUTHOR]

Objectives To evaluate the impact of More Learning for Interns in Emergency ( MoLIE) on clinical documentation in the ED of a large regional hospital. Methods MoLIE was implemented at The Townsville Hospital ( TTH) in 2010, and has since provided ED interns with structured off-floor teaching and a dedicated clinical supervisor. A pre- and post-intervention study was conducted using retrospective medical record review methodology. Charts were selected by identifying all TTH ED patients seen by interns in the period 2008-2011. Two hundred pre-intervention records (2008-2009) and 200 post-intervention records (2010-2011) were reviewed. These were randomly selected following an initial screen by an ED staff specialist. The quality of clinical documentation for five common ED presentations (asthma, chest pain, lacerations, abdominal pain and upper limb fractures) was assessed. For each presentation, documentation quality was scored out of 10 using predefined criteria. An improvement of two or more was thought to be clinically significant. Mean scores for each group were compared using a Student's t-test for independent samples. Results Mean documentation scores (and 95% confidence intervals) were 5.55 (5.17-5.93) in 2008, 5.42 (4.98-5.86) in 2009, 6.37 (5.99-6.75) in 2010 and 6.08 (5.71-6.45) in 2011. There was a statistically but not clinically significant improvement in scores pre- and post-intervention ( P ≤ 0.001). Conclusion The introduction of MoLIE was associated with a small but statistically significant improvement in documentation, despite an 80% increase in intern placements. These results suggest that structured training programmes have potential to improve intern performance while simultaneously enhancing training capacity. The impact on quality of care requires further evaluation. [ABSTRACT FROM AUTHOR]

Prenatal maternal stress can adversely affect birth outcomes, likely reflecting effects of maternal stress hormones on fetal development. Maternal stress might also induce behavioural changes, such as dietary change, that might influence fetal development. Few studies have documented relationships between stress and dietary change in pregnancy. We analysed stress and dietary change among 222 pregnant women exposed to the 2011 Queensland Floods. We assessed women's objective hardship, subjective distress and cognitive appraisal of the disaster; changes in their diets and their associations with infants' gestational age, weight, length and head circumference at birth, head circumference to birth length ratio (HC/BL) and ponderal index. Greater objective hardship was correlated with more negative dietary change, skipped meals and skipped multivitamins. There were no direct effects of stress or dietary change on birth outcomes. However, we observed an interactive effect of dietary change and exposure timing on head circumference for gestational age (HC for GA) ( p = 0.010) and a similar trend for HC/BL ( p = 0.064). HC for GA and HC/BL were larger among children whose mothers experienced negative changes to their diet in early pregnancy compared with later pregnancy, consistent with a 'head-sparing' response with early gestation exposure. Further analyses indicated that dietary change mediates the relationship between objective hardship because of the floods and these outcomes. This is the first report of relationships among an independent stressor, dietary change and birth outcomes. It highlights another possible mechanism in the relationship between prenatal maternal stress and child development that could guide future research and interventions. [ABSTRACT FROM AUTHOR]
