Aims: Researchers were invited by Aboriginal leaders to collaborate on this study which aimed to assess food intake in the Walgett Aboriginal community to inform long-term community-led efforts to improve food and water security and nutrition.

Methods: Aboriginal adults living in or near Walgett, a remote community in north-west NSW, Australia, completed an adapted Menzies Remote Short-item Dietary Assessment Tool, which was administered verbally and face-to-face in early 2022. Aboriginal people were involved in the survey design, training and collection, and analysis of data. Descriptive statistics were tabulated, overall and by gender, age, and location. Differences by sex, age group (18-44 years versus ≥45 years), and location (Walgett town or other) were determined using a chi-square test.

Results: A total of 242 participants completed the survey; 55% were female. Three-quarters of participants reported meeting the recommendations for discretionary foods (73%); however, more than half (56%) exceeded the recommended maximum serves of sugar-sweetened beverages. The proportion of participants meeting core food group guidelines was 72% for meat, 36% for fruit, 20% for bread and cereals, 6% for dairy, and 3% for vegetables. Overall, none of the participants met the recommended serves of all food groups outlined in the Australian Dietary Guidelines.

Conclusion: Findings show that Walgett Aboriginal community members surveyed were consuming a healthier diet than national data reported for Aboriginal and Torres Strait Islander people in Australia. However, none of the participants were meeting all of the national dietary guidelines, placing them at increased risk of diet-related chronic disease. Local Aboriginal community-led efforts to improve food and water security should include specific strategies to improve nutrition.

Aim: Patients with acute ischaemic stroke are more likely to develop refeeding syndrome due to increased need for nutritional support when suffering alterations of consciousness and impairment of swallowing. This study aimed to evaluate the incidence, risk factors and outcomes of refeeding syndrome in stroke patients.

Methods: This was a retrospective observational study, using the prospective stroke database from hospital, included all consecutive acute ischaemic stroke patients who received enteral nutrition for more than 72 h from 1 January 2020 and 31 December 2022. Refeeding syndrome was defined as occurrence of new-onset hypophosphataemia within 72 h after enteral feeding. Multiple logistic regression analysis was conducted to evaluate risk factors and relationships between refeeding syndrome and stroke outcomes.

Results: 338 patients were included in the study. 50 patients (14.8%) developed refeeding syndrome. Higher scores on National Institutes of Health Stroke Scale and Nutritional Risk Screening 2002, albumin <30 g/L and BMI <18.5 kg/m² were risk factors for refeeding syndrome. Moreover, refeeding syndrome was independently associated with a 3-month modified Rankin Scale score of >2 and 6-month mortality.

Conclusions: Refeeding syndrome was common in stroke patients and higher baseline National Institutes of Health Stroke Scale, higher Nutritional Risk Screening 2002, albumin <30 g/L and BMI <18.5 kg/m² were independent risk factors of refeeding syndrome. Occurrence of refeeding syndrome was significantly associated with higher 3-month modified Rankin Scale and 6-month mortality.

Aims: Immune checkpoint inhibitor therapy used for lung cancer has significantly changed response and survival rates, however, the impact on patients' nutritional status remains largely unexplored. This review aims to identify common adverse events that increase nutrition risk induced in non-small cell lung cancer patients treated with immune checkpoint inhibitor therapy and assess impact on nutritional status.

Methods: PubMed, Medline and CINAHL were systematically searched in September 2023 for randomised controlled trials comparing immune checkpoint inhibitor treatment of non-small cell lung cancer to a control group. Treatment-related adverse events that increased nutrition impact symptoms identified in the patient-generated subjective global assessment and clinical guidelines were extracted and qualitatively analysed. Risk of bias was assessed using Cochrane Risk of Bias tool 2.

Results: Eleven eligible randomised controlled trial studies were identified and analysed. The data demonstrated immune checkpoint inhibitor treatment was associated with a lower percentage of reported nutrition impact symptoms, for example, decreased appetite, nausea, vomiting, compared to chemotherapy treatment. Conversely, immune checkpoint inhibitor treated patients recorded a greater percentage of immune-related adverse events that alter metabolism or nutrient absorption.

Conclusion: Non-small cell lung cancer patients treated with immune checkpoint inhibitors still experience nutrition impact symptoms but less frequently than patients treated with chemotherapy. This combined with unique nutrition-related consequences from colitis and thyroid disorders induced by immune checkpoint inhibitor therapy indicates patients should be screened, assessed and interventions implemented to improve nutrition.

Aim: This study aimed to explore food insecurity prevalence and experiences of adults with severe mental illness living in Northern England.

Methods: This mixed-methods cross-sectional study took place between March and October 2022. Participants were adults with self-reported severe mental illness living in Northern England. The survey included demographic, health, and financial questions. Food insecurity was measured using the US Department of Agriculture Adult Food Security measure. Quantitative data were analysed using descriptive statistics and binary logistic regression; and qualitative data using content analysis.

Results: In total, 135 participants completed the survey, with a mean age of 44.7 years (SD: 14.1, range: 18-75 years). Participants were predominantly male (53.3%), white (88%) and from Yorkshire (50.4%). The food insecurity prevalence was 50.4% (n = 68). There was statistical significance in food insecurity status by region (p = 0.001); impacts of severe mental illness on activities of daily living (p = 0.02); and the Covid pandemic on food access (p < 0.001). The North West had the highest prevalence of food insecurity (73.3%); followed by the Humber and North East regions (66.7%); and Yorkshire (33.8%). In multivariable binary logistic regression, severe mental illness' impact on daily living was the only predictive variable for food insecurity (odds ratio = 4.618, 95% confidence interval: 1.071-19.924, p = 0.04).

Conclusion: The prevalence of food insecurity in this study is higher than is reported in similar studies (41%). Mental health practitioners should routinely assess and monitor food insecurity in people living with severe mental illness. Further research should focus on food insecurity interventions in this population.

Aims: Hospital inpatients often eat poorly and report barriers related to mealtime care. This study aimed to measure and describe the mealtime environment and care practices across 16 acute wards in a tertiary hospital to identify opportunities for improvement.

Methods: A prospective cross-sectional audit was undertaken over a two-month period in 2021. A structured audit tool was used at one breakfast, lunch and dinner on each ward to observe the mealtime environment (competing priorities, lighting, tray table clutter) and care practices (positioning, tray within reach, mealtime assistance). Data were analysed descriptively (%, count), with analyses by meal period and ward to identify variation in practices.

Results: A total of 892 observations were completed. Competing priorities (59%), poor lighting (43%) and cluttered tray tables (41%) were common. Mealtime assistance was required by 300 patients (33.6%; 5.9% eating assistance, 27.7% set-up assistance) and was provided within 10 min for 203 (66.7%) patients. A total of 54 patients (18.0%) did not receive the required assistance. We observed 447 (50.2%) patients lying in bed at meal delivery, with 188 patients (21.1%) sitting in a chair. Competing priorities, poor lighting, poor patient positioning and delayed assistance were worse at breakfast. Mealtime environments and practices varied between wards.

Conclusion: This audit demonstrates opportunities to improve mealtimes in our hospital. Variation between wards and meal periods suggest that improvements need to be tailored to the ward-specific barriers and enablers. Dietitians are ideally placed to lead a collaborative approach alongside the wider multidisciplinary team to improve mealtime care and optimise intake.

Aims: This systematic review aims to describe the dietary quality, dietary intake and related behaviours of adults diagnosed with cystic fibrosis.

Methods: A comprehensive literature search was conducted in four databases (Medline, CINAHL, EMBASE, CENTRAL); studies were included if they addressed dietary intake, diet quality or eating behaviours among adults (≥15 years) living with cystic fibrosis and were published from January 2000 to November 2022. The Mixed Methods Appraisal Tool was used to assess the risk of bias and quality of included studies. Findings were synthesised narratively.

Results: Nineteen observational studies (n = 2236) were included and considered high to moderate quality. Most (13/19) studies reported that individuals with cystic fibrosis were consuming high-energy diets; where studies reported energy intake as a proportion of requirements met, energy intake was high, even when using individualised or cystic fibrosis-specific referents. In addition, fat intakes as a proportion of energy appeared high (29%-39% of total energy), particularly as current guidelines recommend macronutrient profile similar to the general population (<30% of total energy). There was considerable variation in the reporting of fatty acid profiles and other nutrients. Five studies reported on concerns regarding diet and eating in this population.

Conclusion: Findings from the current review suggest dietary intakes of adults with cystic fibrosis appear to be less than optimal and concerns about diet, weight and food may be emerging in this population. Future research utilising consistent measures of dietary assessment and reporting, reporting of medical therapies, and exploring potential concerns about diet and eating is warranted.

Aims: To test a model of malnutrition screening and assessment conducted by dietetics students on placement in residential aged care facilities. The secondary aim was to identify possible facilitators and barriers to the implementation of the model.

Method: The type 1 hybrid effectiveness-implementation trial study design and reporting outcomes were developed using the Consolidated Framework for Implementation Research. An innovative placement model was developed, where students on voluntary placement visited three residential aged care facilities to identify residents at risk of malnutrition using currently available screening tools for older people. Students completed malnutrition assessments for all residents using the subjective global assessment tool.

Results: Thirty-two students participated; 31 completed all three sessions, with malnutrition screening completed for 207 residents and malnutrition assessment for 187 residents (July and September 2022). Based on the subjective global assessment, 31% (n = 57) of residents were mildly/moderately malnourished, and 3% (n = 5) were severely malnourished. The Innovation Domain of the Framework was the most important consideration before implementation.

Conclusion: Whilst previous research documented student learning opportunities in residential aged care facilities, this study provides the first available evidence of the direct contribution students can make to the health of aged care residents through malnutrition screening and assessment. The model enables students to conduct malnutrition screening and assessment feasibly and efficiently in facilities that do not routinely collate and act on these data. With a limited nursing aged care workforce to undertake this vital task, the potential role of student dietitians to fulfil this role must be considered.

Aim: Malnutrition is common in older adults in aged care homes, partly due to inadequate protein intake. Menu planning guidelines are available however, adherence to guidelines is unknown. This study aimed to determine; (i) what are the average serving sizes of menu items provided and do they meet recommended portion sizes? (ii) does consumption from a 'typical' menu provide sufficient protein? and (iii) can substituting a 'typical' menu with high-protein options enable residents to achieve protein adequacy?

Methods: This study involved 572 residents (73% female; aged 86.4 ± 7.3 years) from 60 aged-care homes in Australia involved in a 2-year cluster-randomised trial. During the trial, food intake was recorded quarterly using visual estimation of plate-waste and 42 061 foods analysed. As part of a secondary analysis of these data, portion sizes of foods were compared to guidelines by calculating the mean (95% confidence interval). Items were deemed inadequate if the upper 95% confidence interval remained below recommended portion sizes.

Results: On average 47% of breakfast and 80% of lunch/dinner items were below recommended portion sizes. Relative protein intakes, from a typical menu (most consumed foods), was 0.9 g and 0.8 g/kg body weight/day for females and males; both below recommendations. Substituting regular items with higher protein equivalents increased protein intake to 1.3 g and 1.2 g/kg body weight/day, for females and males, respectively.

Conclusion: Aged care homes in Australia are not meeting menu planning guidelines resulting in insufficient protein being provided. Reform to menu guidelines including provision of high-protein foods, will ensure protein adequacy in older adults in aged-care homes.

Aim: To evaluate an 'On-Demand' snack service in a rehabilitation setting for satisfaction, intake, waste and cost.

Methods: In September 2021, a trial of an 'On-Demand' snack service was conducted on two general rehabilitation wards in a purpose-built rehabilitation hospital. A retrospective comparison of pre-implementation, 1-month and 8-month post-implementation audit data was used to evaluate staff and patient satisfaction, nutritional intake, waste and cost (labour and food). Descriptive and inferential statistical analyses were performed for intake quantitative data and content analysis was conducted for qualitative data.

Results: A total of 26 responses from staff and 34 from patients were received. Staff reported higher overall satisfaction with the 'tea-trolley' service (50% vs. 32%; χ² 6.815 [2]; p < 0.05). Patient satisfaction ratings of the original 'tea-trolley' system were higher than the 'On-Demand' snacks system (96% vs. 59%; χ² 41.60 [2]; p < 0.0001). Median daily intake from snack food and drinks was maintained (938 kJ and 6 g protein vs. 925 kJ and 6 g protein) and waste (23.3% vs. 20.9%; p < 0.05) decreased with the 'On-Demand' service. Cost of ordered food was similar ($778.15 'tea-trolley' vs. $746.1 'On-Demand'), however cost of waste ($179.47 'tea-trolley' vs. $128.7 'On-Demand') and labour ($1650.46 'tea-trolley' vs. $926.44 'On-Demand') reduced by 28% and 44%, respectively, with the 'On-Demand' snack service.

Conclusion: Implementing an 'On-Demand' snack service in the general inpatient rehabilitation setting resulted in reductions in food waste, foodservice staff labour and waste costs, while intake was maintained. Patient and staff satisfaction decreased warranting further investigation into appropriate implementation methods.
