We calculated the attributable cost of several healthcare-associated infections in a community hospital network: central-line–associated bloodstream infections (CLABSIs), catheter-associated urinary tract infections (CAUTIs), hospital-onset Clostridioides difficile infections (CDI-HOs) (43 hospitals); surgical site infections (SSIs) (40 hospitals). From 2016 to 2022, the total cost of CLABSIs, CAUTIs, CDI-HOs, and SSIs was $420,012,025.

The aim of the present study was to develop the ASKFV-SE tool to measure self-efficacy (SE) towards requesting fruits and vegetables (FV) in the home and school environment with school-age children (grades 4–5) from urban, ethnically diverse, low-income households. Cognitive interviews reduced the tool from eleven items to seven. The 7-item questionnaire was tested with 444 children. The items loaded on two factors: home SE (four items) and school SE (two items) with one item was excluded (<0⋅40). The reduced 6-item, 2-factor structure was the best fit for the data (χ2 = 45⋅09; df = 9; CFI = 0⋅835; RMSEA = 0⋅147). Confirmatory factory analysis revealed that the 4-item home SE had high reliability (α = 0⋅73) and marginally acceptable reliability for the 2-item school SE (α = 0⋅53). The pre-COVID intra-class correlation coefficient (ICC) was 0⋅584 (P < 0⋅001; fair; n = 57) compared to 0⋅736 during-COVID (P < 0⋅001; good; n 50). The ASKFV-SE tool measures children's SE for asking for FVs with strong psychometric properties and low participant burden.

OBJECTIVES/GOALS: Intermuscular adipose tissue (IMAT) has been associated with insulin resistance and type 2 diabetes, yet mechanistic studies addressing the functional role of IMAT are lacking. The aim of this work was to identify novel mechanisms by which IMAT may directly impact skeletal muscle metabolism. METHODS/STUDY POPULATION: We quantified the secretome of IMAT, subcutaneous adipose tissue (SAT), and visceral adipose tissue (VAT) to determine if there are differences between depots in the secretion of cytokines, eicosanoids, FFAs and proteins that influence metabolic function. SAT and VAT biopsies from patients undergoing laparoscopic bariatric surgery and IMAT extracted from vastus lateralis biopsies of individuals with Obesity were cultured for 48 hours in DMEM, and the conditioned media was analyzed using nanoflow HPLC-MS, multiplex ELISAs and LC/MS/MS for proteins, cytokines and eicosanoids/FFA, respectively. RESULTS/ANTICIPATED RESULTS: IMAT secretion of various extracellular matrix proteins (fibrinogen-β, collagenV1a3, fibronectin) was significantly different than VAT and SAT. Pro-inflammatory cytokine secretion of IFNg, TNFa, IL-8 and IL-13 from IMAT was higher than VAT and significantly higher than SAT (p < 0.05). IMAT secretes significantly more pro-inflammatory eicosanoids TXB2 and PGE2 than VAT (p = 0.02, 0.05) and SAT (p = 0.01, 0.04). IMAT and VAT have significantly greater basal lipolysis assessed by FFA release rates compared to SAT (p = 0.01, 0.04). DISCUSSION/SIGNIFICANCE OF IMPACT: These data begin to characterize the disparate secretory properties of SAT, VAT and IMAT and suggest a metabolically adverse secretome of IMAT, that due to its proximity to skeletal muscle may play an important functional role in the pathogenesis of insulin resistance and type 2 diabetes.

In this essay I defend an alternative account of why markets are legitimate. I argue that markets have a raison d’être—a potential to be valuable that, if fulfilled, would justify their existence. I characterize this potential in terms of the goods that are promoted by the legal protection of economic agency: resource discretion, contribution esteem, wealth, diffusion of power, and freedom of association. I argue that market institutions deliver these goods without requiring the participants to have shared ends, or shared deliberation about joint ends—indeed, this feature is the source of the market’s distinctive contribution to well-being. I suggest that when markets lack legitimacy, this is because they fail to fulfill their raison d’être, or fail to be recognized as doing so. Thus, the contours of legal protection must be drawn so that these goods are realized together in a recognizable way, without sacrificing one good for the sake of others. Finally, I argue that this account is appealing because it allows regulators to consider a plurality of goods, and because it makes room for the essential role of rhetoric in securing market legitimacy.

Inflammatory bowel disease (IBD) is a risk factor for the development of colon cancer. Environmental factors including diet and the microflora influence disease outcome. Folate and homocysteine have been associated with IBD-mediated colon cancer but their roles remain unclear. We used a model of chemically induced ulcerative colitis (dextran sodium sulphate (DSS)) with or without the colon carcinogen azoxymethane (AOM) to determine the impact of dietary folic acid (FA) on colonic microflora and the development of colon tumours. Male mice (n 15 per group) were fed a FA-deficient (0 mg/kg), control (2 mg/kg) or FA-supplemented (8 mg/kg) diet for 12 weeks. Folate status was dependent on the diet (P< 0·001) and colitis-induced treatment (P= 0·04) such that mice with colitis had lower circulating folate. FA had a minimal effect on tumour initiation, growth and progression, although FA-containing diets tended to be associated with a higher tumour prevalence in DSS-treated mice (7–20 v. 0 %, P= 0·08) and the development of more tumours in the distal colon of AOM-treated mice (13–83 % increase, P= 0·09). Folate deficiency was associated with hyperhomocysteinaemia (P< 0·001) but homocysteine negatively correlated with tumour number (r − 0·58, P= 0·02) and load (r − 0·57, P= 0·02). FA had no effect on the intestinal microflora. The present data indicate that FA intake has no or little effect on IBD or IBD-mediated colon cancer in this model and that hyperhomocysteinaemia is a biomarker of dietary status and malabsorption rather than a cause of IBD-mediated colon cancer.

Cutaneous malignant melanoma (CMM) is a major health issue in Queensland, Australia, which has the world's highest incidence. Recent molecular and epidemiologic studies suggest that CMM arises through multiple etiological pathways involving gene–environment interactions. Understanding the potential mechanisms leading to CMM requires larger studies than those previously conducted. This article describes the design and baseline characteristics of Q-MEGA, the Queensland Study of Melanoma: Environmental and Genetic Associations, which followed up 4 population-based samples of CMM patients in Queensland, including children, adolescents, men aged over 50, and a large sample of adult cases and their families, including twins. Q-MEGA aims to investigate the roles of genetic and environmental factors, and their interaction, in the etiology of melanoma. Three thousand, four hundred and seventy-one participants took part in the follow-up study and were administered a computer-assisted telephone interview in 2002–2005. Updated data on environmental and phenotypic risk factors, and 2777 blood samples were collected from interviewed participants as well as a subset of relatives. This study provides a large and well-described population-based sample of CMM cases with follow-up data. Characteristics of the cases and repeatability of sun exposure and phenotype measures between the baseline and the follow-up surveys, from 6 to 17 years later, are also described.

The neural representation of peripersonal space may be distinct from the representation of extrapersonal space. Sex differences in the performance of motor tasks might relate to proximity to the body. In the spatial domain, females excel at tasks performed in peripersonal space, like the Object Location Memory Task (OLMT), whereas males excel at tasks performed in extrapersonal space, such as navigation. We compared performance on the OLMT in peripersonal space with performance on the same task in extrapersonal space (using a between-subjects design). As predicted, the typical female advantage was observed for the peripersonal OLMT. However, for the extrapersonal OLMT, the female advantage disappeared and males actually outperformed females. These results suggest that the sex differences observed in the OLMT, and potentially other tasks that exhibit sex differences in performance, may be related to sex differences to spatial-motor systems that are preferentially tuned to proximity.

This paper reports on the processes experienced in the development of a language programme in a high school in the western suburbs of Sydney in 2006 and represents the ideas and views of the two key participants. We consider the different perspectives held by the key participants on the project and how these need to be worked through in order to come to a place where the two (or more) systems of knowing and learning can be symbiotic rather than pushing against one another. The two systems being referred to are, in brief, a Western academic position, held by the linguist on the project, and an Indigenous intuitive position, held by the language tutor on the project. We report on the steps forward and backward in this process and how the participants felt and dealt with the emotional and intellectual demands incurred throughout the process. Much of this “two steps forward, one step back” process has resulted from the struggle for the non-Indigenous linguist to understand the Indigenous tutor’s knowledge, input and feelings. Likewise the tutor had to come to understand the linguist’s knowledge base and what she was trying to do. We hope that this paper will open up many issues for consideration and discussion such as collaborative research, teaching and learning and working as a partnership.

Young people leaving care are expected to become independent at a far earlier age than are young people who are fortunate enough to have supportive families. High rates of unstable accommodation, unemployment, poverty and early parenthood, have been found in research studies into the outcomes for young people leaving care. Governments have a duty of care to provide resources and support to ensure that young people leaving care experience a safe and sustainable transition to independence. Key elements of best practice framework are outlined in this article for this to be achieved.
