Current clinical guidelines for people at risk of heart disease in Australia recommend nutrition intervention in conjunction with pharmacotherapy(1). However, Australians living in rural and remote regions have less access to medical nutritional therapy (MNT) provided by Accredited Practising Dietitians (APDs) than their urban counterparts(2). The aim of the HealthyRHearts study was to trial the delivery of MNT by APDs using telehealth to eligible patients of General Practitioners (GPs) located in small to large rural towns in the Hunter New England region(3) of New South Wales, Australia. The study design was a 12-month pragmatic randomised controlled trial. The key outcome was reduced total cholesterol. The study was place-based, meaning many of the research team and APDs were based rurally, to ensure the context of the GPs and patients was already known. Eligible participants were those assessed as moderate-to-high risk of CVD by their GP. People in the intervention group received five MNT consults (totalling two hours) delivered via telehealth by APDs, and also answered a personalised nutrition questionnaire to guide their priorities and to support personalised dietary behaviour change during the counselling. Both intervention and control groups received usual care from their GP and were provided access to the Australian Eating Survey (Heart version), a 242-item online food frequency questionnaire with technology-supported personalised nutrition reports that evaluated intake relative to heart healthy eating principles. Of the 192 people who consented to participate, 132 were eligible due to their moderate-to-high risk. Pre-post participant medication use with a registered indication(4) for hypercholesterolemia, hypertension and glycemic control were documented according to class and strength (defined daily dose: DDD)(5). Nine GP practices (with 91 participants recruited) were randomised to the intervention group and seven practices (41 participants) were randomised to control. Intervention participants attended 4.3 ± 1.4 out of 5 dietetic consultations offered. Of the132 people with baseline clinical chemistry, 103 also provided a 12-month sample. Mean total cholesterol at baseline was 4.97 ± 1.13 mmol/L for both groups, with 12-m reduction of 0.26 ± 0.77 for intervention and 0.28 ± 0.79 for control (p = 0.90, unadjusted value). Median (IQR) number of medications for the intervention group was 2 (1–3) at both baseline and 12 months (p = 0.78) with 2 (1–3) and 3 (2–3) for the control group respectively. Combined DDD of all medications was 2.1 (0.5–3.8) and 2.5 (0.75–4.4) at baseline and 12 months (p = 0.77) for the intervention group and 2.7 (1.5–4.0) and 3.0 (2.0–4.5) for the control group (p = 0.30). Results suggest that medications were a significant contributor to the management of total cholesterol. Further analysis is required to evaluate changes in total cholesterol attributable to medication prescription relative to the MNT counselling received by the intervention group.

Creating a sustainable residency research program is necessary to develop a sustainable research pipeline, as highlighted by the recent Society for Academic Emergency Medicine 2024 Consensus Conference. We sought to describe the implementation of a novel, immersive research program for first-year emergency medicine residents. We describe the curriculum development, rationale, implementation process, and lessons learned from the implementation of a year-long research curriculum for first-year residents. We further evaluated resident perception of confidence in research methodology, interest in research, and the importance of their research experience through a 32-item survey. In two cohorts, 25 first-year residents completed the program. All residents met their scholarly project requirements by the end of their first year. Two conference abstracts and one peer-reviewed publication were accepted for publication, and one is currently under review. Survey responses indicated that there was an increase in residents’ perceived confidence in research methodology, but this was limited by the small sample size. In summary, this novel resident research curriculum demonstrated a standardized, reproducible, and sustainable approach to provide residents with an immersive research program.

The expensive-tissue hypothesis (ETH) posited a brain–gut trade-off to explain how humans evolved large, costly brains. Versions of the ETH interrogating gut or other body tissues have been tested in non-human animals, but not humans. We collected brain and body composition data in 70 South Asian women and used structural equation modelling with instrumental variables, an approach that handles threats to causal inference including measurement error, unmeasured confounding and reverse causality. We tested a negative, causal effect of the latent construct ‘nutritional investment in brain tissues’ (MRI-derived brain volumes) on the construct ‘nutritional investment in lean body tissues’ (organ volume and skeletal muscle). We also predicted a negative causal effect of the brain latent on fat mass. We found negative causal estimates for both brain and lean tissue (−0.41, 95% CI, −1.13, 0.23) and brain and fat (−0.56, 95% CI, −2.46, 2.28). These results, although inconclusive, are consistent with theory and prior evidence of the brain trading off with lean and fat tissues, and they are an important step in assessing empirical evidence for the ETH in humans. Analyses using larger datasets, genetic data and causal modelling are required to build on these findings and expand the evidence base.

This paper contributes to an increasingly critical assessment of a policy framing of ‘financial resilience’ that focuses on individual responsibility and financial capability. Using a participatory research and design process, we construct a ground-up understanding of financial resilience that acknowledges not only an individual’s actions, but the contextual environment in which they are situated, and how those relate to one another. We inductively identify four inter-connected dimensions of relational financial resilience: infrastructure (housing, health, and childcare), financial and economic factors (income, expenses, and financial services and strategies), social factors (motivation and community and family), and the institutional environment (policy and local community groups, support and advice services). Consequently, we recommend that social policies conceptualise financial resilience in relational terms, as a cross-cutting policy priority, rather than being solely a facet of individual financial capability.

In July 2021, Public Health Wales received two notifications of salmonella gastroenteritis. Both cases has attended the same barbecue to celebrate Eid al–Adha, two days earlier. Additional cases attending the same barbecue were found and an outbreak investigation was initiated. The barbecue was attended by a North African community’s social network. On same day, smaller lunches were held in three homes in the social network. Many people attended both a lunch and the barbecue. Cases were defined as someone with an epidemiological link to the barbecue and/or lunches with diarrhoea and/or vomiting with date of onset following these events. We undertook a cohort study of 36 people attending the barbecue and/or lunch, and a nested case-control study using Firth logistic regression. A communication campaign, sensitive towards different cultural practices, was developed in collaboration with the affected community. Consumption of a traditional raw liver dish, ‘marrara’, at the barbecue was the likely vehicle for infection (Firth logistic regression, aOR: 49.99, 95%CI 1.71–1461.54, p = 0.02). Meat and offal came from two local butchers (same supplier) and samples yielded identical whole genome sequences as cases. Future outbreak investigations should be relevant to the community affected by considering dishes beyond those found in routine questionnaires.
