The Prevalence and Compliance of Health Claims Used in the Labelling and Information for Prepacked Foods within Great Britain

In the EU and Great Britain (GB), all health claims (HCs) on food must be authorised before use and should comply with Regulation 1924/2006. In GB, all HCs, authorised or not, are listed in the Great Britain Nutrition and Health Claims Register. This study reviews the prevalence and compliance of HCs on prepacked foods sold within three GB supermarkets and via their grocery shopping websites. In June 2023, food labels and online product information of 440 products were evaluated across three food categories—dairy and dairy alternatives; fruit juices, fruit juice drinks and fruit smoothies; and teas and infusions. In store, 26.3% of products carried an HC and 28.3% online. The prevalence of HCs was higher when compared with data from 2016. Overall compliance was high, in store (94.3%) and online (90.0%), with no statistically significant difference in overall HC compliance between in store and online products (p = 0.724). The HC violations observed in the present study were due to non-compliant wording of HCs or use of non-authorised HCs. This study demonstrates changes in the HC landscape and the need for continued monitoring of the prevalence and compliance of HCs as consumer trends alter

Paramedic views regarding clinical research in out of hospital cardiac arrest

Background: The success of pre-hospital research relies on positive engagement from paramedics. Without adequate participation and protocol compliance trials will not succeed. Aims: To seek feedback from paramedics about trial participation and determine their preferences regarding a future large-scale research study. Methods: Paramedics participating in REVIVE-Airways were sent a feedback questionnaire according to their study allocation. Findings: 99% of respondents were willing to participate in a further large-scale trial. Participants offered recommendations for future pre-hospital trials. Conclusion: There was strong support for further clinical trials of alternative airway management strategies during OHCA. Paramedics welcome opportunities to participate in research and receive feedback about trial progress and patient outcomes

Wheat NAC transcription factor <i>NAC5‐1</i> is a positive regulator of senescence

Wheat (Triticum aestivum L.) is an important source of both calories and protein in global diets, but there is a trade‐off between grain yield and protein content. The timing of leaf senescence could mediate this trade‐off as it is associated with both declines in photosynthesis and nitrogen remobilization from leaves to grain. NAC transcription factors play key roles in regulating senescence timing. In rice, OsNAC5 expression is correlated with increased protein content and upregulated in senescing leaves, but the role of the wheat ortholog in senescence had not been characterized. We verified that NAC5‐1 is the ortholog of OsNAC5 and that it is expressed in senescing flag leaves in wheat. To characterize NAC5‐1, we combined missense mutations in NAC5‐A1 and NAC5‐B1 from a TILLING mutant population and overexpressed NAC5‐A1 in wheat. Mutation in NAC5‐1 was associated with delayed onset of flag leaf senescence, while overexpression of NAC5‐A1 was associated with slightly earlier onset of leaf senescence. DAP‐seq was performed to locate transcription factor binding sites of NAC5‐1. Analysis of DAP‐seq and comparison with other studies identified putative downstream target genes of NAC5‐1 which could be associated with senescence. This work showed that NAC5‐1 is a positive transcriptional regulator of leaf senescence in wheat. Further research is needed to test the effect of NAC5‐1 on yield and protein content in field trials, to assess the potential to exploit this senescence regulator to develop high‐yielding wheat while maintaining grain protein content

Treat-to-target in PsA: methods and necessity

© Author(s) (or their employer(s)) 2020. Re-use permitted under CC BY-NC. No commercial re-use. See rights and permissions. Published by BMJ. With increasing recognition of the high burden and impact of psoriatic arthritis (PsA) and the growing number of therapeutic options, there has been an intensifying focus on treatment strategy in recent years. In 2015, the Tight Control of Psoriatic Arthritis study confirmed the clinical benefit of using a treat-to-target approach in PsA. This randomised controlled trial found benefits in both arthritis and psoriasis disease activity as well as lower disease impact reported by patients, although participants allocated to tight control experienced a higher rate of serious adverse events. European and international recommendations support the use of a treat-to-target approach in PsA and have offered specific advice on how to do this using outcomes such as the minimal disease activity criteria. However, implementation of this approach in routine practice is low, with real-world data highlighting undertreatment as a result. Recent qualitative work with physicians in the UK has helped researchers to understand the barriers to implementation of treat-to-target in PsA. We now need to address these barriers, provide education and support to non-specialist clinicians in routine practice, and aid the translation of optimal care to the clinic

Rise and diversification of chondrichthyans in the Paleozoic

The Paleozoic represents a key time interval in the origins and early diversification of chondrichthyans (cartilaginous fishes), but their diversity and macroevolution are largely obscured by heterogenous spatial and temporal sampling. The predominantly cartilaginous skeletons of chondrichthyans pose an additional limitation on their preservation potential and hence on the quality of their fossil record. Here, we use a newly compiled genus-level dataset and the application of sampling standardization methods to analyze global total-chondrichthyan diversity dynamics through time from their first appearance in the Ordovician through to the end of the Permian. Subsampled estimates of chondrichthyan genus richness were initially low in the Ordovician and Silurian but increased substantially in the Early Devonian. Richness reached its maximum in the middle Carboniferous before dropping across the Carboniferous/Permian boundary and gradually decreasing throughout the Permian. Sampling is higher in both the Devonian and Carboniferous compared with the Silurian and most of the Permian stages. Shark-like scales from the Ordovician are too limited to allow for some of the subsampling techniques. Our results detect two Paleozoic radiations in chondrichthyan diversity: the first in the earliest Devonian, led by acanthodians (stem-group chondrichthyans), which then decline rapidly by the Late Devonian, and the second in the earliest Carboniferous, led by holocephalans, which increase greatly in richness across the Devonian/Carboniferous boundary. Dispersal of chondrichthyans, specifically holocephalans, into deeper-water environments may reflect a niche expansion following the faunal displacement in the aftermath of the Hangenberg extinction event at the end of the Devonian

Promoting Fruit and Vegetable Consumption for Childhood Obesity Prevention

Currently, food marketing for unhealthy foods is omnipresent. Foods high in fat, salt, and sugar (HFSS) are advertised intensively on several media platforms, including digital platforms that are increasingly used by children, such as social media, and can be bought almost everywhere. This could contribute to the obesity epidemic that we are facing. As the majority of children and adolescents do not eat the recommended amount of fruits and vegetables (F&V), which leads to chronic diseases, we need to change the obesogenic environment to a healthogenic environment. Reducing the marketing of energy-dense snacks to children and increasing the promotion of healthier foods, such as fruits and vegetables, may be an effective and necessary instrument to improve the dietary intake of children and reduce the risk of their experiencing some chronic diseases later in life. With this focused narrative review, we provide an overview of how children and adolescents react to food promotions and how food promotional efforts might be a useful tool to increase the attractiveness of fruit and vegetables. This review therefore contributes to the question of how changing the advertising and media environment of children and adolescents could help create a world where the healthy choice is the easier choice, which would reduce childhood obesity and improve children’s health, as well as to make the food system more sustainable

Mixed methods study of clinicians' perspectives on barriers to implementation of treat to target in psoriatic arthritis

Objectives: In treat to target (T2T), the patient is treated to reach and maintain specified and sequentially measured goals, such as remission or low disease activity. T2T in psoriatic arthritis (PsA) has demonstrated improved clinical and patient-reported outcomes and is recommended in European guidelines. However, most clinicians do not use T2T in PsA. This study examined the barriers and enablers to implementation in practice. Methods: Sequential mixed methods comprising a qualitative design (interviews and focus group) to inform a quantitative design (survey). Qualitative data were analysed thematically, and quantitative statistics were analysed descriptively. Results: Nineteen rheumatology clinicians participated in telephone interviews or a face-to-face focus group. An overarching theme 'Complexity' (including 'PsA vs Rheumatoid Arthritis', 'Measurement' and 'Resources') and an underpinning theme 'Changes to current practice' (including 'Reluctance due to organisational factors' and 'Individual determination to make changes') were identified. 153 rheumatology clinicians responded to an online survey. Barriers included limited clinical appointment time to collect outcome data (54.5%) and lack of training in assessing skin disease (35%). Enablers included provision of a protocol (86.4%), a local implementation lead (80.9%), support in clinic to measure outcomes (83.3%) and training in T2T (69.8%). The importance of regular audit with feedback, specialist PsA clinics and a web-based electronic database linked to hospital/national information technology (IT) systems were also identified as enablers. Conclusions: Implementation of T2T in PsA requires an integrated approach to address the support, training and resource needs of individual clinicians, rheumatology teams, local IT systems and service providers to maximise success
