Two firewood species (beech and olive) were used for grilling three meat types (lamb, pork, and veal) to assess their influence on the sensorial properties of meat. A multimethod approach was adopted, including sensory evaluation with consumers and two analytical techniques to characterize the volatile fraction (Solid-Phase Micro-Extraction Gas Chromatography-Mass Spectrometry [SPME-GC/MS] and electronic nose [e-nose]). The sensory session included three pairwise preference tests (one for each type of meat), an overall liking test, a Rate-All-That-Apply test, and a questionnaire on the interest and perceived value of using sustainably certified firewood in food preparation. The firewood species significantly affected the perception of a few crucial attributes. In particular, olive wood increased the roasted meat flavor perception in lamb and veal, while beech wood increased the perceived intensity of a vegetable/herbaceous flavor in veal. No effect of firewood was observed on preference within each pair of meat samples. Lamb was the significantly most liked meat by consumers, followed by pork; veal was the least liked meat type. Positive and negative drivers of preference were discussed. 36 volatile organic compounds were identified from SPME-GC/MS in meats. Congruently with sensory data, the two veal samples showed a greater distance in terms of volatile composition. Relative distances among samples on maps obtained from SPME-GC/MS and the e-nose were similar. This multi-method approach innovatively showed the potential of using firewood as a \'gastronomic\' tool to sensorially characterize and valorize cooked meat.

BACKGROUND: Ultra-processed food (UPF) is currently not included in most countries\' dietary guidance. However, there may be growing public interest and consumer avoidance of UPF due to media reporting of studies on the negative health outcomes associated with UPFs.
METHODS: We surveyed 2386 UK adults (M age = 45 years, 50% female) during February-April 2024. Participants completed measures on awareness of the term UPF, whether the UPF status of foods affects their dietary decision-making, and confidence in identifying UPFs. Participants categorised a list of 10 foods (5 UPFs and 5 non-UPFs) as UPF vs. not, before rating whether information about studies linking UPF to worse health impacts on their negative affect and acts as a deterrent to consuming UPFs.
RESULTS: Most participants (73%) were aware of the term UPF and 58% reported that their food choices are determined by whether they believe a food is ultra-processed or not. Participants with the highest income and education levels were most likely to report both being aware of, and, avoiding consuming UPFs. Most participants could not accurately categorise whether foods were UPFs. Some sociodemographic groups (e.g., higher education levels) were more likely to accurately categorise UPFs but were also more likely to incorrectly believe that non-UPFs were UPFs. Participants tended to report that UPF-health risk information increases negative affect and acts as a deterrent to consuming UPFs.
CONCLUSIONS: In this study, a large number of UK adults reported avoiding consuming UPFs. This was particularly pronounced among those with the highest education and income levels.

OBJECTIVE: Aged care staff and doctors frequently highlight consumers\' role in antibiotic treatment decisions. However, few studies include consumers. This study aimed to investigate consumer perspectives on antibiotic use in residential aged care.
METHODS: A search across six online databases yielded 3373 studies, with five meeting inclusion criteria. Participant quotes, themes, statistical analyses, and authors\' interpretive summaries in the included studies were inductively coded and refined to generate themes.
RESULTS: Three themes emerged: perception of benefits and risks of antibiotics; perceived role in antibiotic treatment decision-making and information-communication needs. Consumers held positive attitudes towards antibiotics, did not associate antibiotics with the exclusive treatment of bacterial infections, and had limited awareness of potential risks, such as antibiotic resistance. Studies showed diverse perceptions regarding residents\' and their families\' involvement in antibiotic treatment decision-making with some residents actively seeking antibiotics and others trusting doctors to decide. Studies also described consumer need for effective provider-consumer communication and information sharing which was affected by contextual barriers such as motivation, preferences, available information resources, and provider attitudes.
CONCLUSIONS: Limited literature is available on consumer perspectives on antibiotic use in aged care. The review highlights that consumer needs are more complex than simply wanting an antibiotic. Antimicrobial stewardship programs should target consumer awareness, beliefs and provider-consumer communication to enhance antibiotic use in aged care.

BACKGROUND: Engagement and partnership with consumers and communities throughout research processes produces high quality research meeting community needs and promoting translation of research into improved policy and practice. Partnership is critical in research involving Aboriginal and/or Torres Strait Islander people (First Nations Peoples) to ensure cultural safety. We present lessons from the design, implementation and progress of the National Health and Medical Research Council funded INtravenous iron polymaltose for First Nations Australian patients with high FERRitin levels on hemodialysis (INFERR) clinical trial.
METHODS: The trial was designed to understand the benefits and harms of iron therapy in First Nations Australians on haemodialysis with anaemia and hyperferritinaemia. The lack of evidence for treatment was discussed with patients who were potential participants. A key element ensuring safe conduct of the INFERR trial was the establishment of the Indigenous Reference Groups (IRGs) comprising of dialysis patients based in the Top End of Australia and Central Australia. Two IRGs were needed based on advice from First Nations communities and researchers/academics on the project regarding local cultural differences and approaches to trial conduct. The IRGs underpin culturally safe trial conduct by providing input into study materials and translating study findings into effective messages and policies for First Nations dialysis patients. Throughout the trial conduct, the IRGs\' role has developed to provide key mechanisms for advice and guidance regarding research conduct both in this study and more broadly. Support provided to the IRGs by trial First Nations Research Officers and independent First Nations researchers/academics who simplify research concepts is critical. The IRGs have developed feedback documents and processes to participants, stakeholders, and the renal units. They guarantee culturally safe advice for embedding findings from the trial into clinical practice guidelines ensuring evidence-based approaches in managing anaemia in haemodialysis patients with hyperferritinaemia.
CONCLUSIONS: Active consumer and community partnership is critical in research conduct to ensure research impact. Strong partnership with consumers in the INFERR clinical trial has demonstrated that First Nations Consumers will engage in research they understand, that addresses health priorities for them and where they feel respected, listened to, and empowered to achieve change.
In this paper, we present the importance of actively involving consumers in the planning, implementation and conduct of research using the example of a clinical trial among Aboriginal and/or Torres Strait Australians (First Nations Australians) who have kidney disease and are currently receiving haemodialysis. The study assesses how safe and effective it is for people on dialysis to receive iron given through the vein during dialysis when they have anaemia and high levels of a blood test called ferritin, a test used routinely to measure iron levels. Two consumer reference groups of First Nations patients on dialysis, one based in the Top End of Australia and the other based in Central Australia, are supported by First Nations Research Officers and Research Academics to make sure that the research is performed in a way that involves, respects and values First Nations participation, culture, and knowledge. Active consumer and community partnership in this study has supported robust research governance processes which we believe are crucial for knowledge translation to have a positive impact for patients.

BACKGROUND: The use of finished herbal products (FHPs) among Malaysians today is expanding rapidly leading to a huge market of FHPs in the country. However, the mass production of FHPs in today\'s market is alarming due to safety-use issues that could lead to serious adverse effects. Nevertheless, demands are still high for FHPs as most consumers perceived it as safe to consume as it is made from natural substances as the active ingredients. This study aims to explore the safe use elements of FHPs identified by two stakeholders: consumers and practitioners in Malaysia and further compare these elements with the current regulations.
METHODS: As an exploratory study, its approach is to investigate at an in-depth level of understanding of safe use elements from the involved stakeholders: consumers and practitioners. We had a total of 4 focus group discussion sessions (1 FGD session with consumer and 3 FGD sessions with practitioners) as a method of collecting data from the participants. The FGDs were conducted in local native Malaysian and then being translated by researchers without changing their meanings. Thematic analysis was done which involves methodically reading through the verbatim transcripts and consequently segmenting and coding the text into categories that highlight what the participants have discussed.
RESULTS: From the result, we found that both practitioners and consumers agreed a safe FHP must be in compliance with the guidelines from the Ministry of Health Malaysia (MOH). There are other safe use elements highlighted including halal certification, trusted over-the-counter outlets, and published reports on the safety, efficacy, and quality.
CONCLUSIONS: In conclusion, both practitioners and consumers agreed that the most important safe-use element is compliance with MOH guidelines, but the depth of discussion regarding the safety elements among these stakeholders holds a very huge gap. Thus, initiatives must be planned to increase the knowledge and understanding about the MOH guidelines towards achieving a sustainable ecosystem in the safe use of FHPs.

The increasing levels of heavy metals in aquatic environments, driven by human activities, pose a critical threat to ecosystems\' overall health and sustainability. This study investigates the bioaccumulation of heavy metals (Pb, Cu, Cr, and Cd) in water, sediment, and three fish species (Catla catla, Labeo rohita, Cirrhinus mrigala) of different feeding zones within Chashma Barrage, located in the Mianwali district of Punjab, Pakistan, on the Indus River. A comprehensive analysis, including an assessment of associated human health risks, was conducted. Thirty samples from all three sites for each fish species, with an average body weight of 160 ± 32 g, were collected from Chashma Barrage. Water quality parameters indicated suitability for fish growth and health. Heavy metal concentrations were determined using an atomic absorption spectrometer. Results indicated elevated levels of Cd, Cr, and Cu in sediment and Pb and Cd in water, surpassing WHO standard limits. Among the fish species, bottom feeder (C. mrigala) exhibited significantly (P < 0.05) higher heavy metal levels in its tissues (gills, liver, and muscle) compared to column feeder (L. rohita) and surface feeder (C. catla). Liver tissues across all species showed higher heavy metal bioaccumulation, followed by gills. Principal component analysis (PCA) revealed strong correlations among heavy metals in sediment, gills, muscle, and water in every fish species. However, the vector direction suggests that Cr was not correlated with other heavy metals in the system, indicating a different source. The human health risk analysis revealed lower EDI, THQ, and HI values (< 1) for the fish species, indicating no adverse health effects for the exposed population. The study emphasizes the bioaccumulation differences among fish species, underscoring the higher heavy metal concentrations in bottom feeder fish within Chashma Barrage.

Assessments of ecosystem functioning are a fundamental ecological challenge and an essential foundation for ecosystem-based management. Species trophic position (TP) is essential to characterize food web architecture. However, despite the intuitive nature of the concept, empirically estimating TP is a challenging task due to the complexity of trophic interaction networks. Various methods are proposed to assess TPs, including using different sources of organic matter at the base of the food web (the \'baseline\'). However, it is often not clear which methodological approach and which baseline choices are the most reliable. Using an ecosystem-wide assessment of a tropical reef (Marquesas Islands, with available data for 70 coral reef invertebrate and fish species), we tested whether different commonly used TP estimation methods yield similar results and, if not, whether it is possible to identify the most reliable method. We found significant differences in TP estimates of up to 1.7 TPs for the same species, depending on the method and the baseline used. When using bulk stable isotope data, the choice of the baseline significantly impacted TP values. Indeed, while nitrogen stable isotope (δ15N) values of macroalgae led to consistent TP estimates, those using phytoplankton generated unrealistically low TP estimates. The use of a conventional enrichment factor (i.e. 3.4‰) or a \'variable\' enrichment factor (i.e. according to feeding guilds) also produced clear discrepancies between TP estimates. TPs obtained with δ15N values of source amino acids (compound-specific isotope analysis) were close to those assessed with macroalgae. An opposite seasonal pattern was found, with significantly lower TPs in winter than in summer for most species, with particularly pronounced differences for lower TP species. We use the observed differences to discuss possible drivers of the diverging TP estimates and the potential ecological implications.

Successful promotion of cage-free eggs supports a housing system offering potential for improved hen welfare. As the world\'s largest egg producer and consumer, China offers much potential for welfare improvements. We examined 10 Chinese companies supplying cage-free eggs (four using indoor systems, six with outdoor access) to understand their strategies to promote cage-free eggs to businesses and consumers. We purposively sampled 12 employees from these companies familiar with production or sales. We conducted two-three semi-structured interviews per participant, collected public online documents (including online shops and social media content), and recorded field notes. We analyzed the data using template analysis to generate key results. Participants reported buyers being unfamiliar with \'animal welfare\' and \'cage-free\', but familiar with concepts associated with \'free-range\'. Participants considered three attributes when promoting cage-free eggs: price (engaging buyers who were willing to pay more), experiential attributes (e.g., taste, accommodating buyer preferences), and non-sensory credence attributes (e.g., cage-free production, improving buyers\' understanding and trust). Our results are not generalizable, though they may be transferable to similar contexts. Understanding how companies promoted cage-free eggs to buyers may help inform promotion of other animal products with welfare attributes. Simultaneous efforts are needed to ensure actual welfare improvements on farms.

The consumption of added sugars has been a major concern among consumers and researchers around the world. Some of these added sugars pose health threats such as obesity, and liver diseases to consumers. Therefore, consumers\' understanding and knowledge of added sugars is important in regulating the intake of food items that contain different types and levels of added sugar. In this study, the knowledge and understanding of staff (consumers) of the University of Energy and Natural Resources, Ghana, was assessed through survey The results showed that about 38.5 % of consumers always read food labels whereas 3.1 % never read the labels of food they purchased. However, only about 20 % of consumers considered added sugars as most important information on food labels while most (about 38 %) were concerned about the calorie level in food items purchased. Based on the consumer\'s knowledge of sugars and sweeteners, there was a high level of disparity in classifying sugars in food as sugars and sweeteners. In addition, most consumers reported that they would adversely avoid food items containing lactose, isoglucose, and saccharin. The awareness of the consumers to the WHO recommendation for sugar reduction, the gender (P = 0.278), age (P = 0.959), level of education (P = 0.888), and staff category (P = 0.944) did not influence their decisions on purchasing food items with added sugars Most consumers were interested in issues of food and nutrition. Therefore, it is recommended that staff are taken through aspects of food nutrition as well as the consumption of added sugar towards the recommended levels.
