The Barriers and Facilitators of Sport and Physical Activity Participation for Aboriginal Children in Rural New South Wales, Australia: A Photovoice Project.

Participating in physical activity is beneficial for health. Whilst Aboriginal children possess high levels of physical activity, this declines rapidly by early adolescence. Low physical activity participation is a behavioral risk factor for chronic disease, which is present at much higher rates in Australian Aboriginal communities compared to non-Aboriginal communities. Through photos and 'yarning', the Australian Aboriginal cultural form of conversation, this photovoice study explored the barriers and facilitators of sport and physical activity participation perceived by Aboriginal children (n = 17) in New South Wales rural communities in Australia for the first time and extended the limited research undertaken nationally. Seven key themes emerged from thematic analysis. Four themes described physical activity barriers, which largely exist at the community and interpersonal level of children's social and cultural context: the physical environment, high costs related to sport and transport, and reliance on parents, along with individual risk factors such as unhealthy eating. Three themes identified physical activity facilitators that exist at the personal, interpersonal, and institutional level: enjoyment from being active, supportive social and family connections, and schools. Findings highlight the need for ongoing maintenance of community facilities to enable physical activity opportunities and ensure safety. Children held strong aspirations for improved and accessible facilities. The strength of friendships and the family unit should be utilized in co-designed and Aboriginal community-led campaigns.

Utility of the Cell Index in Predicting External Ventricular Drain-Related Ventriculo-Meningitis.

BACKGROUND/OBJECTIVE: Ventriculo-meningitis (VM) is an important complication of external ventricular drains (EVDs) in neurosurgical patients. Consequences include increased morbidity, mortality, and duration of hospital stay. Early diagnosis of EVD-associated VM allows earlier treatment intervention. The cell index (CI) may provide a simple measure that overcomes the limitations of isolated cerebrospinal fluid (CSF) parameters and other diagnostic tests, allowing earlier prediction of VM. METHODS: All patients admitted to a tertiary hospital and requiring EVD insertion during 2015 and 2016 were assessed for inclusion in this retrospective case-control study. Patients with a known or suspected intracranial infection were excluded. Of the 186 patients who underwent EVD insertion, 95 patients were included in the final cohort. Data pertaining to patient characteristics and laboratory indices were extracted from health records and the microbiology laboratory database. The CI was calculated as the ratio of temporally related CSF leukocytes/erythrocytes to peripheral blood leukocytes/erythrocytes. Data from patients with microbiologically confirmed VM were analyzed in comparison with those not developing VM during the course of their stay. Categorical and continuous variables with skewed distributions were analyzed by Chi square and Mann-Whitney tests, respectively. RESULTS: EVD-associated VM developed in 7.4% of patients. The highest CSF CI (within 3 days prior to diagnosis of VM or at any time for those not developing VM) differed significantly between the two groups (16; IQR 10.8-48.5 vs. 3.3; IQR 1.0-12.8, respectively; p = .046). The area under the receiver operating characteristic curve (AUROC) for the highest CI was 0.727 (95% confidence interval [CI] 0.526-0.929; p = .027). A CI of 10.4 provided a sensitivity and specificity of 80.5% and 70.5%, respectively, for the early diagnosis of VM. CONCLUSIONS: In neurosurgical patients with an EVD, the CSF CI significantly predicted the development of VM.

Is the length of time in acute burn surgery associated with poorer outcomes?

BACKGROUND: Acute wound closure surgery improves outcomes, after burn particularly mortality, but also imposes physiological stress on the patient. The duration of surgery is associated with adverse outcomes in other populations. This study aimed to examine if extended acute burn surgery duration was associated with poorer in-hospital outcomes. METHODS: This retrospective cohort study included adult burn patients who required a single wound closure surgery at Royal Perth Hospital between 2004 and 2011. Multivariable regression analyses were used to assess the influence of patient and injury factors on surgery duration and length of stay (LOS). RESULTS: Surgery duration independently increased LOS (incidence rate ratio [IRR]=1.004, p<0.001). This translates to a predicted 13% increase in LOS for a 30min increase in surgery 'knife to skin' time. Total body surface area (TBSA) was identified as a significant predictor of surgery duration (IRR=1.047, p<0.001), estimating that a 10% TBSA increase results in a 59% increase in surgery duration. CONCLUSION: The results show that surgery duration is associated with LOS after adjusting for size of burn and other factors. The study justifies the need to explore strategies to reduce acute burn surgery duration.
