Objective: Obesity rates have increased in children in Australia in the past 15 years. However, there is little available population data describing rates of overweight and obesity in Aboriginal children. Methods: Anthropometric data of four-year-old children (n=11,859) were collected by trained nurses at routine statewide preschool health checks during 2009. Weight status (underweight, healthy weight, overweight and obese) was determined using age and gender specific International Obesity Task Force (IOTF) cut-points. Results: There were 337 Aboriginal children (3%) in the study population. Aboriginal children had significantly higher rates of overweight and obesity compared to non-Aboriginal children (28% compared to 18% respectively, χ 2p=0. 0001). A statistically signifcant association between BMIz score and identifying as Aboriginal remained after controlling for rural/urban residence and socioeconomic status using multiple regression analyses. Conclusions: Aboriginal children have higher rates of overweight and obesity compared to their non-Aboriginal peers by the time they are four years of age. Aboriginal children have higher BMIz scores compared to non-Aboriginal children after controlling for rural/urban residence and socioeconomic status. Implications: A signifcant investment is required to optimise the health of Aboriginal women before pregnancy and throughout pregnancy. A rethink may be necessary in the approach to dietary management and catch-up growth of Aboriginal children of low birth weight or having growth failure in early childhood. © 2012 Public Health Association of Australia.

This qualitative study aimed to gain an in-depth understanding of the adaptation of children and families to childhood chronic illness. Considering ecological theories and child empowerment, we departed from the usual practice of relying solely on parental report by also soliciting children?s views. Eighteen children aged 7-14 with cancer, chronic renal failure or type 1 diabetes, and 21 of their parents, participated. The inclusion of several conditions enabled the examination of data from a categorical versus non-categorical perspective. Focus groups supplemented by individual interviews explored participants? views about challenges and the processes they considered important in enhancing adaptation to a chronic illness. Children, as well as parents, provided rich material. Thematic analysis revealed 11 main themes. Six concerned the impact of the illness on various aspects of life. The other main themes were the meaning of disease, stress-processing, social support, future concerns and psychosocial interventions. There were many similarities and some differences between parent and child reports. Many issues were common across illness groups, consistent with a non-categorical approach, though there were some illness-specific issues, especially for those with cancer. Positive as well as negative material emerged. Implications for clinical services are discussed. Source

Introduction: Methods for improving patient safety are predicated on cooperation between healthcare groups, but are the views of health professionals involved in promoting safety shared by other healthcare workforce staff and managers? Aim: To compare patient-safety suggestions from health workforce managerial and staff groups with those of patient-safety specialists. Method: Samples of managers (424) and staff (1214) in the South Australian state health system and 131 Australian patient-safety specialists were asked to write suggestions for improving patient safety. Group responses were content analysed and compared. Results: Patient-safety specialists (83.2%) were more likely to make suggestions than were workforce managers (57.8%) or staff (44.1%). Workforce members from clinical professions were more likely than non-clinicians to tender suggestions. No relationship existed between the importance specialists and managers (ρ=-0.062, p=0.880) and specialists and staff (ρ=-0.046, p=0.912) attached to nine categories of suggestions. There was a high correlation between the importance that managers and nonmanagers attached to safety strategies (ρ=0.817, ρ=0.011). Among those who made suggestions, specialists were more likely to suggest implementing reviews and guidelines, and incident reporting. Workforce groups were more likely to recommend increased and improved staffing and staffing conditions, and better equipment and infrastructure. There were no significant differences in the proportions of group members recommending: improving management and leadership; increasing staff safety education and supervision; communication and teamwork; improved patient focus; or tackling specific safety projects. Implications: Differences between safety specialists' and workforce groups' beliefs about how to improve patient safety may impede the successful implementation of patient-safety programmes. Source

Saturated fatty acids promote lipotoxic ER (endoplasmic reticulum) stress in pancreatic β-cells in association with Type 2 diabetes. To address the underlying mechanisms we employed MS in a comprehensive lipidomic screen of MIN6β-cells treated for 48 h with palmitate. Both the overall mass and the degree of saturation of major neutral lipids and phospholipids were only modestly increased by palmitate. The mass of GlcCer (glucosylceramide) was augmented by 70% under these conditions, without any significant alteration in the amounts of either ceramide or sphingomyelin. However, flux into ceramide (measured by [3H]serine incorporation) was augmented by chronic palmitate, and inhibition of ceramide synthesis decreased both ERstress and apoptosis. ER-to-Golgi protein trafficking was also reduced by palmitate pre-treatment, but was overcome by overexpression of GlcCer synthase. This was accompanied by increased conversion of ceramide into GlcCer, and reduced ER stress and apoptosis, but no change in phospholipid desaturation. Sphingolipid alterations due to palmitate were not secondary to ER stress since they were neither reproduced by pharmacological ER stressors nor overcome using the chemical chaperone phenylbutyric acid. In conclusion, alterations in sphingolipid, rather than phospholipid, metabolism are more likely to be implicated in the defective protein trafficking and enhanced ER stress and apoptosis of lipotoxic β-cells. ©The Authors Journal compilation ©2011 Biochemical Society.

Although survival of children with acute lymphoblastic leukaemia has improved greatly in the past two decades, the outcome of those who relapse has remained static. We investigated the outcome of children with acute lymphoblastic leukaemia who relapsed on present therapeutic regimens. This open-label randomised trial was undertaken in 22 centres in the UK and Ireland and nine in Australia and New Zealand. Patients aged 1-18 years with first relapse of acute lymphoblastic leukaemia were stratified into high-risk, intermediate-risk, and standard-risk groups on the basis of duration of first complete remission, site of relapse, and immunophenotype. All patients were allocated to receive either idarubicin or mitoxantrone in induction by stratified concealed randomisation. Neither patients nor those giving interventions were masked. After three blocks of therapy, all high-risk group patients and those from the intermediate group with postinduction high minimal residual disease (≥10-4 cells) received an allogenic stem-cell transplant. Standard-risk and intermediate-risk patients with postinduction low minimal residual disease (<10-4 cells) continued chemotherapy. The primary outcome was progression-free survival and the method of analysis was intention-to-treat. Randomisation was stopped in December, 2007 because of differences in progression-free and overall survival between the two groups. This trial is registered, reference number ISCRTN45724312. Of 239 registered patients, 216 were randomly assigned to either idarubicin (109 analysed) or mitoxantrone (103 analysed). Estimated 3-year progression-free survival was 35·9 (95 CI 25·9-45·9) in the idarubicin group versus 64·6 (54·2-73·2) in the mitoxantrone group (p=0·0004), and 3-year overall survival was 45·2 (34·5-55·3) versus 69·0 (58·5-77·3; p=0·004). Differences in progression-free survival between groups were mainly related to a decrease in disease events (progression, second relapse, disease-related deaths; HR 0·56, 0·34-0·92, p=0·007) rather than an increase in adverse treatment effects (treatment death, second malignancy; HR 0·52, 0·24-1·11, p=0·11). As compared with idarubicin, mitoxantrone conferred a significant benefit in progression-free and overall survival in children with relapsed acute lymphobastic leukaemia, a potentially useful clinical finding that warrants further investigation.
