Background: To determine the prevalence of enteric infections in Aboriginal children aged 0-2 years using conventional and molecular diagnostic techniques and to explore associations between the presence of pathogens and child growth.Methods: Cross-sectional analysis of Aboriginal children (n = 62) residing in a remote community in Northern Australia, conducted from July 24th - October 30th 2017. Stool samples were analysed for organisms by microscopy (directly in the field and following fixation and storage in sodium-acetate formalin), and by qualitative PCR for viruses, bacteria and parasites and serology for Strongyloides-specific IgG. Child growth (height and weight) was measured and z scores calculated according to WHO growth standards.Results: Nearly 60% of children had evidence for at least one enteric pathogen in their stool (37/62). The highest burden of infection was with adenovirus/sapovirus (22.9%), followed by astrovirus (9.8%) and Cryptosporidium hominis/parvum (8.2%). Non-pathogenic organisms were detected in 22.5% of children. Ten percent of children had diarrhea at the time of stool collection. Infection with two or more pathogens was negatively associated with height for age z scores (- 1.34, 95% CI - 2.61 to - 0.07), as was carriage of the non-pathogen Blastocystis hominis (- 2.05, 95% CI - 3.55 to - 0.54).Conclusions: Infants and toddlers living in this remote Northern Australian Aboriginal community had a high burden of enteric pathogens and non-pathogens. The association between carriage of pathogens/non-pathogens with impaired child growth in the critical first 1000 days of life has implications for healthy child growth and development and warrants further investigation. These findings have relevance for many other First Nations Communities that face many of the same challenges with regard to poverty, infections, and malnutrition. [ABSTRACT FROM AUTHOR]

This study describes the illness narratives that inform treatment-seeking behaviours for acute abdominal conditions in Cambodia, and thereby explores factors impeding the timely delivery of surgical intervention. Semi-structured qualitative interviews were undertaken with patients who had undergone abdominal surgery at Siem Reap Provincial Hospital between 2011 and 2014. Interviews collected basic demographic information and also patient narratives based on Groleau's McGill Illness Narrative Interview (MINI). Interviews were contemporaneously translated from Khmer to English and recorded for transcription. A content analysis of interview transcripts based on narrative enquiry was undertaken. Ninety-seven patients participated in the study and five themes emerged from the data. These were: Explanatory models about the causes of abdominal pain and effects of surgery; Pre-surgery stoicism and illness management; Fear of poor outcomes and death; Burden of treatment costs and anticipated recovery time; and, Enhancing community trust in surgery. Our findings add the patient voice to the limited evidence about access to surgery, and socio-cultural and financial barriers affecting treatment-seeking behaviours in Cambodia. By understanding the collective narratives surrounding experiences of abdominal surgery, efforts to improve surgical services in Cambodia may be better informed of the reasons patients delay treatment.

Learning in the high reliability domain has vital importance where public safety is dependant on the expertise and proficiency of practitioners. Air traffic control is one example of work that may be characterized as a technologically complex, high stress, real-time environment with little margin for error. This study investigates learning in the air traffic control workplace in the context of workplace changes, which required all experienced controllers to act as instructors of trainee controllers. Initially prescribed as a strategy to enhance organizational flexibility and to increase workplace efficiency, the initiative was shown to have unintended effects. The results reported show how an incidental and unintended reciprocal learning opportunity (through engaging in on-the-job-training) enriches the reflective learning process for instructors. Organizational strategies, which serve to refresh the expertise of practitioners while addressing the needs of workplace training, offer wide-ranging benefits in the high reliability domain where reflective practices are necessarily limited by the intensity and immediacy of the work.

Strongyloides stercoralis is endemic in tropical and subtropical countries, and is prevalent particularly in economically impoverished people. Although an estimated 30 to 100 million people world-wide suffer from S. stercoralis infection and it is a life-long disease, it remains a neglected tropical disease. Faecal testing for S. stercoralis is very insensitive. The prevalence of S. stercoralis in Indigenous Australians (up to 60%) is much higher than previously thought, and its prevalence in Papua New Guinea is likely to be much higher than currently believed. When S. stercoralis and the HTLV-1 virus coexist in the one person, both diseases progress more quickly than when either infection is on its own. When people become infected with S. stercoralis, they develop acute strongyloidiasis which may be life threatening. At any time during the course of the disease, if the immune system is suppressed, most often by corticosteroid drugs, infected people may develop hyperinfective strongyloidiasis and they will die unless the underlying S. stercoralis infection is effectively treated. The use of serology for diagnosis, together with ivermectin treatment, has revealed that it is possible to eradicate S. stercoralis from the patient, and serology can also define the effectiveness of treatment. The reservoir of infection is humans; the free-living stages are short-lived. Mass treatment may be effective at eliminating S. stercoralis from a community. Safe water and effective sanitation alone do not lead to elimination of S. stercoralis. Up-to-date knowledge of S. stercoralis has been revealed through the workshops of the National Strongyloides Working Group in Australia and is summarized here. Much of this information is now available on the world wide web, and the addresses of relevant web sites are given.
