- Abstract
Background: Low back pain (LBP) is ranked in the top 10 conditions presenting to emergency departments (ED) in Australia. We aimed to investigate ED re-presentation rates and length of stay (LOS) of patients with LBP, including associated factors., Methods: We reviewed medical records of three EDs in Sydney, Australia from January 2016 to October 2021. The primary outcome was the proportion of episodes of non-serious LBP with at least one re-presentation within 12 months. Secondary outcomes were re-presentation rates within 3-days, 1-week, 1-month, 3-months, 6-months, and mean LOS. Multivariable logistic regression analyses were performed to investigate the associated factors with re-presentation and prolonged stay (>4 h) and reported as adjusted odds ratios (aORs) and 95% confidence intervals (95% CI)., Results: Of 8289 episodes of non-serious LBP, 7.7% included at least one re-presentation within 12 months. There were only 14 re-presentations (0.2%) where the diagnosis changed from non-serious LBP at the index visit to serious spinal pathology at the repeat visit. The overall mean LOS was 4.1 h, and 26.9% of patients stayed in the ED for >4 h. Those who received opioids (aOR: 1.31; 95% CI: 1.08-1.59) were more likely to re-present. In contrast, patients receiving imaging were less likely to re-present (aOR: 0.78, 95% CI: 0.65-0.94). Receiving imaging (aOR: 2.83; 95% CI: 2.56-3.13) and opioids (aOR: 1.64; 95% CI: 1.47-1.82) increased the odds of prolonged stay., Conclusion: A re-presentation within 12 months occurs in 7.7% of episodes of LBP in ED. Over one-quarter of patients stayed longer than 4 h., Competing Interests: Declaration of competing interest The authors declare that they have no conflict of interest., (Copyright © 2024 The Authors.

- Abstract
Background: Metagenome-assembled genomes have greatly expanded the reference genomes for skin microbiome. However, the current reference genomes are largely based on samples from adults in North America and lack representation from infants and individuals from other continents., Results: Here we use deep shotgun metagenomic sequencing to profile the skin microbiota of 215 infants at age 2-3 months and 12 months who are part of the VITALITY trial in Australia as well as 67 maternally matched samples. Based on the infant samples, we present the Early-Life Skin Genomes (ELSG) catalog, comprising 9483 prokaryotic genomes from 1056 species, 206 fungal genomes from 13 species, and 39 eukaryotic viral sequences. This genome catalog substantially expands the diversity of species previously known to comprise human skin microbiome and improves the classification rate of sequenced data by 21%. The protein catalog derived from these genomes provides insights into the functional elements such as defense mechanisms that distinguish early-life skin microbiome. We also find evidence for microbial sharing at the community, bacterial species, and strain levels between mothers and infants., Conclusions: Overall, the ELSG catalog uncovers the skin microbiome of a previously underrepresented age group and population and provides a comprehensive view of human skin microbiome diversity, function, and development in early life., (© 2023.

- Abstract
Background: Disparate care in the ED for minority populations with low back pain is a long-standing issue reported in the USA. Our objective was to compare care delivery for low back pain in Australian EDs between culturally and linguistically diverse (CALD) and non-CALD patients., Methods: This is a retrospective review of medical records of the ED of three public hospitals in Sydney, New South Wales, Australia from January 2016 to October 2021. We included adult patients diagnosed with non-serious low back pain at ED discharge. CALD status was defined by country of birth, preferred language and use of interpreter service. The main outcome measures were ambulance transport, lumbar imaging, opioid administration and hospital admission., Results: Of the 14 642 included presentations, 7656 patients (52.7%) were born overseas, 3695 (25.2%) preferred communicating in a non-English language and 1224 (8.4%) required an interpreter. Patients born overseas were less likely to arrive by ambulance (adjusted OR (aOR) 0.68, 95% CI 0.63 to 0.73) than Australian-born patients. Patients who preferred a non-English language were also less likely to arrive by ambulance (aOR 0.82, 95% CI 0.75 to 0.90), yet more likely to be imaged (aOR 1.12, 95% CI 1.01 to 1.23) or be admitted to hospital (aOR 1.16, 95% CI 1.04 to 1.29) than Native-English-speaking patients. Patients who required an interpreter were more likely to receive imaging (aOR 1.43, 95% CI 1.25 to 1.64) or be admitted (aOR 1.49, 95% CI 1.29 to 1.73) compared with those who communicated independently. CALD patients were generally less likely to receive weak opioids than non-CALD patients (aOR range 0.76-0.87), yet no difference was found in the use of any opioid or strong opioids., Conclusion: Patients with low back pain from a CALD background, especially those lacking English proficiency, are significantly more likely to be imaged and admitted in Australian EDs. Future interventions improving the quality of ED care for low back pain should give special consideration to CALD patients., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

- Abstract
Background: Back pain is one of the most common reasons for a person to call an ambulance service, yet how ambulance services manage back pain has not been described., Methods: Australian-state and New Zealand ambulance service jurisdiction websites were searched between 25th January to 3rd February 2022. Pain management guidelines were included where no specific back pain guideline was found. Identified guidelines were screened, appraised using AGREE II tool and recommendations on pharmacological and non-pharmacological management of back pain, ambulance transport and alerting features were extracted, summarised, and compared to two primary care guidelines., Results: Nine guidelines were identified including four back pain and 5 pain management guidelines. All four back pain guidelines recommend paracetamol or ibuprofen as analgesic options to manage back pain. These guidelines recommend transport to the emergency department when there are alerting features for serious disease, lack of pain control or where the patient is unable to ambulate. 2 out of 9 ambulance guidelines were recommended for use in their existing format following quality appraisal using AGREE II tool. Ambulance guidelines scored significantly lower than primary care guidelines for back pain., Conclusion: Ambulance service guidelines for back pain recommend advice, reassurance, paracetamol and referral to primary care., Competing Interests: Declaration of Competing Interest The authors declare that there are no conflicts of interest to disclose., (Copyright © 2022 College of Emergency Nursing Australasia.

- Abstract
The flavors of fermented plant foods and beverages are formed by microorganisms, and in the case of wine, the location and environmental features of the vineyard site also imprint the wine with distinctive aromas and flavors. Microbial growth and metabolism play an integral role in wine production, by influencing grapevine health, wine fermentation, and the flavor, aroma, and quality of finished wines. The contributions by which microbial distribution patterns drive wine metabolites are unclear, and while flavor has been correlated with fungal and bacterial composition for wine, bacterial activity provides fewer sensorially active biochemical conversions than fungi in wine fermentation. Here, we collected samples across six distinct wine-growing areas in southern Australia to investigate regional distribution patterns of fungi and bacteria and the association with wine chemical composition. Results show that both soil and must microbiota distinguish wine-growing regions. We found a relationship between microbial and wine metabolic profiles under different environmental conditions, in particular measures of soil properties and weather. Fungal communities are associated with wine regional distinctiveness. We found that the soil microbiome is a source of grape- and must-associated fungi and suggest that weather and soil could influence wine characteristics via the soil fungal community. Our report describes a comprehensive scenario of wine microbial biogeography where microbial diversity responds to the surrounding environment and correlates with wine composition and regional characteristics. These findings provide perspectives for thoughtful human practices to optimize food composition through understanding fungal activity and abundance. IMPORTANCE The composition of soil has long been thought to provide wine with characteristic regional flavors. Here, we show that for vineyards in southern Australia, the soil fungal communities are of primary importance for the aromas found in wines. We propose a mechanism by which fungi can move from the soil through the vine., (Copyright © 2020 Liu et al.)

- Abstract
Antibodies to glutamic acid decarboxylase (GAD), previously known as the 64-kD pancreatic islet cell autoantigen, are an important serologic marker of insulin-dependent diabetes mellitus (IDDM). Antibodies to GAD (anti-GAD) were examined in sera from Australian children with newly diagnosed IDDM (within 1 mo of diagnosis), IDDM of longer duration (mean +/- SD, 4.8 +/- 3.3 y), and in first-degree relatives, using a radioimmuno-precipitation assay with purified porcine brain GAD as antigen. Antibodies to islet cell cytoplasmic antigens (ICAb) were tested concurrently. The frequency of anti-GAD was not significantly different in children with newly diagnosed IDDM (31 of 42, 74%) and with IDDM of longer duration (14 of 21, 67%), whereas ICAb were present more frequently in children with newly diagnosed IDDM (64%) than in those with longer duration IDDM (14%). In all, 90% of children with newly diagnosed IDDM had either anti-GAD or ICAb, whereas only 48% had both. For the 77 first-degree relatives, the frequency of anti-GAD was 2% (one of 44) in parents and 6% (two of 33) in siblings; ICAb were not detected in any of these relatives. The presence of anti-GAD in the majority of children with IDDM, irrespective of the duration of their disease, represents a useful diagnostic marker for IDDM, and should be of value in ascertaining individuals at risk for developing IDDM.
