The unfolding COVID-19 pandemic has exposed the vulnerability of the Pacific food system to externalities and has had far-reaching impacts, despite the small number of COVID-19 cases recorded thus ...far. Measures adopted to mitigate risk from the pandemic have had severe impacts on tourism, remittances, and international trade, among other aspects of the political economy of the region, and are thus impacting on food systems, food security and livelihoods. Of particular concern will be the interplay between loss of incomes and the availability and affordability of local and imported foods. In this paper, we examine some of the key pathways of impact on food systems, and identify opportunities to strengthen Pacific food systems during these challenging times. The great diversity among Pacific Island Countries and Territories in their economies, societies, and agricultural potential will be an important guide to planning interventions and developing scenarios of alternative futures. Bolstering regional production and intraregional trade in a currently import-dependent region could strengthen the regional economy, and provide the health benefits of consuming locally produced and harvested fresh foods – as well as decreasing reliance on global supply chains. However, significant production, processing, and storage challenges remain and would need to be consistently overcome to influence a move away from shelf-stable foods, particularly during periods when human movement is restricted and during post-disaster recovery.
It is unknown how well menu labelling schemes that enforce the display of kilojoule (kJ) labelling at point-of-sale have been implemented on online food delivery (OFD) services in Australia. This ...study aimed to examine the prevalence of kJ labelling on the online menus of large food outlets with more than twenty locations in the state or fifty locations nationally. A secondary aim was to evaluate the nutritional quality of menu items on OFD from mid-sized outlets that have fewer locations than what is specified in the current scheme.
Cross-sectional analysis. Prevalence of kJ labelling by large food outlets on OFD from August to September 2022 was examined. Proportion of discretionary ('junk food') items on menus from mid-sized outlets was assessed.
Forty-three unique large food outlets on company (e.g. MyMacca's) and third party OFD (Uber Eats, Menulog, Deliveroo) within Sydney, Australia. Ninety-two mid-sized food outlets were analysed.
N/A.
On company OFD apps, 35 % (7/23) had complete kJ labelling for each menu item. In comparison, only 4·8 % (2/42), 5·3 % (2/38) and 3·6 % (1/28) of large outlets on Uber Eats, Menulog and Deliveroo had complete kJ labelling at all locations, respectively. Over three-quarters, 76·3 % (345/452) of menu items from mid-sized outlets were classified as discretionary.
Kilojoule labelling was absent or incomplete on a high proportion of online menus. Mid-sized outlets have abundant discretionary choices and yet escape criteria for mandatory menu labelling laws. Our findings show the need to further monitor the implementation of nutrition policies on OFD.
Extensive literature describes the importance of food environments (FEs) as a driver of food choices and nutrition outcomes; yet existing FE frameworks do not adequately capture the diversity of FEs ...relevant to the Pacific Region. This limits identification of opportunities in food systems to reduce the multiple burden of malnutrition. We present a conceptual typology of FEs including six primary FEs relevant in the Pacific; wild; cultivated; kin and community; informal retail; formal retail; and food aid and services. We then apply this typology to food acquisition data from Solomon Islands 2012/13 Household Income and Expenditure Survey and analyse the relationship between FEs and diet quality. The cultivated FE accounts for 60% of the quantity of food acquired nationally, followed by wild (15%), kin and community (9%), and formal and informal retail FEs (8% each), with wide variation between urban and rural households, provinces and wealth groups. Reliance on different FEs is a significant predictor of diet quality and affirms the importance of subsistence fisheries and agriculture, and community and kinship networks. Integration of a FE typology such as the one presented here in commonly conducted household expenditure surveys offers significant opportunity to advance our understanding of food system leverage points to improve nutrition and health.
Research on food system framework development has increased substantially in recent years to better understand how we can best transform food systems. However, these frameworks generally take a ...one-size-fits-all approach, with food system indicators lacking relevance in many countries and territories. This research, centred on the Solomon Islands as a case study, employed a participatory approach involving stakeholders to identify context-specific indicators across three food systems pathways. These pathways, reflecting context-specific goals and a collective vision, encompassed strengthening and connecting rural food systems, enhancing the national policy environment, and advocating for food environments supporting healthy food accessibility, affordability, and convenience. The research identified a range of context-specific indicators and evaluated their alignment with existing data sources. Results underscored the need for data collection and analysis efforts to inform evidence-based decision-making. The study also emphasised the importance of engaging diverse stakeholders to ensure a comprehensive and representative set of indicators, aligning with regional and global efforts to advance food system resilience and sustainability. This research lays the foundation for future endeavours to enhance food system monitoring and assessment, acknowledging nuances and complexities specific to the Solomon Islands and similar contexts.
Highly pathogenic avian influenza (HPAI) is caused by the haemagglutinin 5, neuraminidase 1 (H5N1) influenza A virus. Around 80% of households in rural Vietnam raise poultry, which provides food ...security and nutrition to their households and beyond. Of these, around 15-20% are semi-commercial producers, producing at least 28% of the country's chicken. Through learning the experiences of these semi-commercial farmers, this study aimed to explore the local understandings and sociocultural aspects of HPAI's impact, particularly the aetiology, diagnosis, and the prevention and control methods in one Vietnamese rural province.
This study was conducted in Quang Tri province, Vietnam. Quang Tri province has eight districts. Five of these districts were at high risk of HPAI during the study period, of which three were selected for the present study. Within these three districts, six communes were randomly selected for the study from the list of intervention communes in Quang Tri province. Six out of the 26 intervention communes in Quang Tri were therefore selected. Participants were randomly selected and recruited from lists of semi-commercial farmers, village animal health workers, village human health workers and local authorities so that the study population (representative population) included an amount of variability similar to that of the wider population.
A key benefit of this village-level control program was the residential proximity of animal and human health professionals. Participants were well aware of the typical clinical signs for avian influenza and of the reporting process for suspect cases. However there was extensive room for improvement in Quang Tri province regarding access to the HPAI vaccine, essential medical equipment for animal use, and available financial support.
This qualitative research study provided an important insight for in-country policy makers and international stakeholders. It is vital that there are continued efforts to prevent and control highly pathogenic avian influenza through support programs that provide locally appropriate information and resources to those at the human-animal interface.
The protease fibroblast activation protein (FAP) is a specific marker of activated mesenchymal cells in tumour stroma and fibrotic liver. A specific, reliable FAP enzyme assay has been lacking. FAP's ...unique and restricted cleavage of the post proline bond was exploited to generate a new specific substrate to quantify FAP enzyme activity. This sensitive assay detected no FAP activity in any tissue or fluid of FAP gene knockout mice, thus confirming assay specificity. Circulating FAP activity was ∼20- and 1.3-fold less in baboon than in mouse and human plasma, respectively. Serum and plasma contained comparable FAP activity. In mice, the highest levels of FAP activity were in uterus, pancreas, submaxillary gland and skin, whereas the lowest levels were in brain, prostate, leukocytes and testis. Baboon organs high in FAP activity included skin, epididymis, bladder, colon, adipose tissue, nerve and tongue. FAP activity was greatly elevated in tumours and associated lymph nodes and in fungal-infected skin of unhealthy baboons. FAP activity was 14- to 18-fold greater in cirrhotic than in non-diseased human liver, and circulating FAP activity was almost doubled in alcoholic cirrhosis. Parallel DPP4 measurements concorded with the literature, except for the novel finding of high DPP4 activity in bile. The new FAP enzyme assay is the first to be thoroughly characterised and shows that FAP activity is measurable in most organs and at high levels in some. This new assay is a robust tool for specific quantitation of FAP enzyme activity in both preclinical and clinical samples, particularly liver fibrosis.

Summary
While food insecurity is a well-known cause of under-nutrition and stunting, in recent decades it has also been linked with obesity. Understanding and thus minimising the risk factors for ...obesity in low- and middle-income country contexts, which often lack the health system capacity to treat the consequent obesity-related illnesses, is crucial. This study adopted realist review methodology because it enabled us to analyse and organise the evidence from low- and middle-income countries into a coherent scheme. By comparing this evidence to existing theory on food security and nutrition, we aimed to provide a richer understanding of the nuances and the socio-demographic nature of the food insecurity–obesity relationship. The review generated 13 peer-reviewed articles which studied the relationship between food insecurity and overweight/obesity in low- and middle-income countries. Affordability of high-energy, processed foods was identified as a main mechanism, which determined whether or not food insecurity leads to obesity in low- and middle-income countries. Other mechanisms identified were: quantity and diversity of food consumed; spatial-temporal access to nutritious food; inter-personal food choice and distribution; and non-dietary behaviours. Despite the limited empirical evidence available, our review presents meaningful and policy-relevant insights into the food insecurity–obesity relationship in from low- and middle-income countries. Interventions to address the food insecurity–obesity link need to address diet quality, and demand a broad understanding across a variety of experiences.
Early estimates suggest that the economic and food system impacts of COVID-19 are likely to worsen these indicators across the region(9). ...it is a critical time to consider the role of research in ...addressing malnutrition effectively across the region. Within the region, there are examples of comprehensive school food policies in Malaysia and South Korea, mandatory interpretive nutrition labelling in Thailand and Sri Lanka, taxes on sugar sweetened beverages in at least sixteen countries and territories and strong restrictions on marketing to children under 12 in Taiwan(4). ...this very much depends on the commodity being traded, and limited research indicates that imports of cheap, energy-dense foods and sugar-sweetened beverages are a concern across the region(25,26). ...the price gap between less healthy foods and healthier foods has widened across the region from 2003 to 2018, with less healthy foods becoming relatively cheaper.
Convenience is a major driver of food choice throughout the world, yet it is often inconsistently conceptualised, defined and measured. This limits the scope for food systems policy and interventions ...to leverage convenience to improve diet and nutrition outcomes. We conducted a systematic literature review to determine how convenience is both defined and measured in food environment and nutrition research. Six databases were systematically searched and studies were screened by two independent reviewers based on pre-defined eligibility criteria, yielding 243 studies for inclusion in the final review. 77% of studies did not explicitly define convenience. Among those that did, the dimensions and components within definitions varied. 83% of studies used perceived measures of convenience rather than objective measures. Convenience was most commonly measured in high income countries (64%) and in relation to the home food environment (53%), followed by formal retail (40%). Very few studies measured convenience in relation to the informal retail or cultivated food environments, and no studies considered convenience in relation to wild food environments. The vast majority of studies did not consider the validity or reliability of the measures of convenience. Based on our findings we propose a definition of convenience as a characteristic that results in reduced requirement for resources including time, physical effort, mental effort and skills by the consumer in relation to the planning, acquisition, preparation, storage, transport, consumption or clean-up of food. This definition can be used to help guide the development of measurement tools that can be used to assess convenience across different dimensions and contexts in a more comprehensive way. We also propose a framework for considering convenience as an entry point in food systems to improve diets and nutrition outcomes.
Background: In Solomon Islands, the retail food environment is an important food source, for instance, the dominant source of fresh fruit and vegetables for urban consumers is open markets. The ...effects of COVID-19 mitigation measures (such as restriction of human movement and border closures) in early 2020 placed food security at risk in many parts of the community. Of particular concern was the risk of price gouging in an already price-sensitive market. Aims: The study aimed to provide rapid and policy-relevant information on the pricing of foods in the urban food environment in Solomon Islands in the context of the unfolding COVID-19 pandemic. Methods: A vendor survey was conducted in July to August 2020 and repeated in July 2021 using a survey tool that collected information on type, quantity, and price of food on offer. Findings: We found price reductions among the majority of fresh fruit and non-starchy vegetables available. A trend of rising prices was reported for some other commodities, such as fresh locally caught fish. Conclusion: Our findings highlight the impact of 'schocks to the system' on food prices as a potential barrier or enabler to consumption of fresh foods purchased from urban areas – an important finding in a price sensitive market. The survey design was successful in collecting pricing data from the retail food environment during a time of external ‘shock to the system’. Our approach is applicable to other settings needing a rapid survey of the external food environment.
