Editorial: Selling a sugar tax: the sweet smell of success?

This editorial briefly considers the increasing epidemic of obesity and Type 2 diabetes, the underlying drivers of junk food and sugary drinks, and the recent scientific and campaigning movements culminating in the UK Chancellor's surprise announcement of a Sugary Drinks Levy

For horses undergoing general anaesthesia, are rope recoveries or free recoveries better?

PICO question: In horses undergoing general anaesthesia, does assistance with ropes result in better recoveries when compared to no assistance (‘free’ recovery)? Clinical bottom line: Category of research question: Treatment The number and type of study designs reviewed: One randomised, non-blinded controlled trial and two retrospective cohort studies Strength of evidence: Weak Outcomes reported: The three studies reviewed arrive at different conclusions regarding the utility of rope assistance in recovery from general anaesthesia in horses, but examine very different populations. The randomised controlled trial provides weak evidence that rope assistance can shorten recovery and improve recovery quality in healthy (American Society of Anesthesiologists (ASA) I–II) horses. One retrospective cohort study provides weak evidence that rope assistance confers a reduction in fatality in both healthy and sick horses. The other retrospective cohort study provides weak evidence that rope assistance confers no benefit to horses undergoing emergency colic surgery. Both assisted and unassisted groups in each study had fatalities and all studies reported complications related to the rope recovery system Conclusion: Insufficient evidence is available to permit a full recommendation regarding rope assistance during recovery from general anaesthesia in horses. Rope assistance may improve recovery time and quality in some horses. The decision to perform a rope-assisted recovery must be made considering individual patient, team and clinic factors. Rope assistance cannot prevent fatalities in recovery How to apply this evidence in practice: The application of evidence into practice should take into account multiple factors, not limited to: individual clinical expertise, patient’s circumstances and owners’ values, country, location or clinic where you work, the individual case in front of you, the availability of therapies and resources. Knowledge Summaries are a resource to help reinforce or inform decision making. They do not override the responsibility or judgement of the practitioner to do what is best for the animal in their care

Food for thought? Potential conflicts of interest in academic experts advising government and charities on dietary policies

Abstract Background A conflict of interest (CoI) can occur between public duty and private interest, in which a public official’s private-capacity interest could improperly influence the performance of their official duties and responsibilities. The most tangible and commonly considered CoI are financial. However, CoI can also arise due to other types of influence including interpersonal relationships, career progression, or ideology. CoI thus exist in academia, business, government and non-governmental organisations. However, public knowledge of CoI is currently limited due to a lack of information. The mechanisms of managing potential conflicts of interest also remain unclear due to a lack of guidelines. We therefore examined the independence of academic experts and how well potential CoI are identified and addressed in four government and non-governmental organisations in the UK responsible for the development of food policy. Methods Policy analysis. We developed an analytical framework to explore CoI in high-level UK food policy advice, using four case studies. Two government policy-making bodies: Department of Health ‘Obesity Review Group’ (ORG), ‘Scientific Advisory Committee on Nutrition’ (SACN) and two charities: ‘Action on Sugar’ (AoS), & ‘Heart of Mersey’ (HoM). Information was obtained from publicly available sources and declarations. We developed a five point ordinal scale based upon the ideology of the Nolan Principles of Public Life. Group members were individually categorised on the ordinal ConScale from “0”, (complete independence from the food and drink industry) to “4”, (employed by the food and drink industry or a representative organisation). Results CoI involving various industries have long been evident in policy making, academia and clinical practice. Suggested approaches for managing CoI could be categorised as “deny”, “describe”, or “diminish”. Declared CoI were common in the ORG and SACN. 4 out of 28 ORG members were direct industry employees. In SACN 11 out of 17 members declared industry advisory roles or industry research funding. The two charities appeared to have equally strong academic expertise but fewer conflicts. No HoM members declared CoI. 5 out of 21 AoS members declared links with industry, mainly pharmaceutical companies. We were unable to obtain information on conflicts for some individuals. Conclusions Conflicts of interest are unavoidable but potentially manageable. Government organisations responsible for policy development and implementation must institutionalize an approach to identify (disclose) and manage (mitigate or eliminate) perceived and actual CoI to improve public confidence in government decision-making relevant to food policy

The role of the food industry in health: lessons from tobacco?

IntroductionIn this review, we highlight poor diet as the biggest risk factor for non-communicable diseases. We examine the denial tactics used by the food industry, how they reflect the tactics previously used by the tobacco industry, and how campaigners can use this knowledge to achieve future public health successes.Sources of dataData sources are wide ranging, notably publications relating to public health, obesity and processed food, the effectiveness hierarchy and food industry denialism tactics.Areas of agreementGlobal burden of disease analyses consistently demonstrate that poor diet produces a bigger burden of non-communicable disease than tobacco, alcohol and inactivity put together. The lessons learnt from the tobacco control experience of successfully fighting the tobacco industry can be applied to other industries including processed food and sugary drinks.Areas of controversyTackling obesity and poor diet is a more complex issue than tobacco. Food industries continue to promote weak or ineffective policies such as voluntary reformulation, and resist regulation and taxation. However, the UK food industry now faces increasing pressure from professionals, public and politicians to accept reformulation and taxes, or face more stringent measures.Growing points and areas timely for developing researchThe rise in childhood and adult obesity needs to be arrested and then reversed. Unhealthy processed food and sugary drinks are a major contributing factor. There is increasing interest in the tactics being used by the food industry to resist change. Advocacy and activism will be essential to counter these denialism tactics and ensure that scientific evidence is translated into effective regulation and taxation

Sugar-sweetened beverages coverage in the British media: an analysis of public health advocacy versus pro-industry messaging

OBJECTIVES: To assess the extent of media-based public health advocacy versus pro-industry messaging regarding sugar-sweetened beverages (SSBs). DESIGN: We conducted a systematic analysis to identify and examine all articles regarding SSBs published in all mainstream British print newspapers and their online news websites from 1 January 2014 to 31 December 2014. We initially conducted a brief literature search to develop appropriate search terms and categorisations for grouping and analysing the articles. Articles were then coded according to the publishing newspaper, article type, topic, prominence and slant (pro-SSB or anti-SSB). A contextual analysis was undertaken to examine key messages in the articles. RESULTS: We identified 374 articles published during 2014. The majority of articles (81%) suggested that SSBs are unhealthy. Messaging from experts, campaign groups and health organisations was fairly consistent about the detrimental effects of SSB on health. However, relatively few articles assessed any approaches or solutions to potentially combat the problems associated with SSBs. Only one-quarter (24%) suggested any policy change. Meanwhile, articles concerning the food industry produced consistent messages emphasising consumer choice and individual responsibility for making choices regarding SSB consumption, and promoting and advertising their products. The food industry thus often managed to avoid association with the negative press that their products were receiving. CONCLUSIONS: SSBs were frequently published in mainstream British print newspapers and their online news websites during 2014. Public health media advocacy was prominent throughout, with a growing consensus that sugary drinks are bad for people's health. However, the challenge for public health will be to mobilise supportive public opinion to help implement effective regulatory policies. Only then will our population's excess consumption of SSBs come under control

Retrospective computed tomography analysis of endotracheal tube constriction & mispositioning in cats & dogs

Objectives: To discover the prevalence of endotracheal tube (ETT) constriction and rostral and caudal mispositioning in anaesthetised cats and dogs, and to identify associated risk factors. Study Design: Retrospective analysis. Animal population: A total of 146 cats, 670 dogs. Methods: Computed tomography images of the head/neck/thorax from orotracheally intubated cats and dogs were visually assessed for constriction or mispositioning of the ETT. If constriction was present, measurements of the cross-sectional area (CSA) of the ETT lumen at constricted and un-constricted locations were compared. Location and cause of constriction were noted and the expected increase in resistance to gas flow was calculated. Animal information was collected from clinical records. Normality of continuous variables was assessed via the Shapiro-Wilk test. Chi square tests examined associations between variables. Kendall’s tau-b test was performed between measured ETT size and degree of constriction. Results: The ETT extended rostrally beyond incisors in 52% of cases; the connector was within the oral cavity in 19% of cases. The ETT extended beyond the first rib in 25.5% of cases. The prevalence of ETT constriction was 22.7%. Median reduction in CSA was 7.68% (0.14–64.19%). Median increase in resistance assuming laminar and turbulent flow was 16.5% (0.3–680%) and 21% (0.3–1200%), respectively. The most common cause of constriction was the presence of a radiotherapy mouth gag. Significant associations existed between presence of constriction and rostral mispositioning, and caudal mispositioning and extreme brachycephaly. Increased severity of constriction was more likely in smaller ETT. Conclusions: And clinical relevance Constriction and mispositioning of ETT occurred very commonly in this population. Checking the ETT within the oral cavity for constriction and mispositioning is recommended. Radiotherapy mouth gags increase the risk of ETT compression. Smaller ETT are at greater risk of severe constriction. Brachycephalic dogs are at particular risk of caudal mispositioning

The EU Settled Status (Wales) data linkage project: Initial findings relating to health and education

Objectives Funded by ADR UK (ESRC) from 2020 to 2023, the project aims to anonymously link European Union Settlement Scheme (EUSS) data with other data already held within the SAIL Databank, based at Swansea University, and produce a research-ready dataset that can be used by researchers to obtain policy-relevant findings. Method Using a range of de-identified data in the SAIL Databank, a control group of British citizens in Wales has been matched with EU citizens with similar characteristics using the Census 2011 as a spine to identify country of birth. The SQL coding programme is used to link Census data with several other datasets in the SAIL Databank relating to health, with a focus on mental health, education and employment. The R software package is used for statistical analysis to produce comparisons between the groups and performing significance tests of these comparisons (e.g. Mann Whitney). Results Initial findings indicate small but statistically significant differences in school attendance between British pupils in Wales and pupils from EU14 and EU8 countries and similar differences in school attainment between British pupils in Wales and pupils from EU14 and EU8 countries. Further analysis has been conducted to explore differences between pupils from EU14 and EU8 countries. Census data are also linked to GP attendance data to explore differences in mental health related consultations and referrals for British citizens in Wales and citizens from EU countries and differences between citizens from EU14 and EU8 countries. Detailed findings from this linking of datasets and analysis will be presented. Conclusion Linking data in this way helps to gain a better understanding of the experiences and outcomes of EU citizens in Wales, generating better evidence to help inform policies and services that address the needs of this population and offers a dataset of great interest to academics

The QUEST for Effective and Equitable Policies to Prevent Non-communicable Diseases: Co-Production Lessons From Stakeholder Workshops

Background: Non-communicable diseases (NCDs) account for some 90% of premature UK deaths, most being preventable. However, the systems driving NCDs are complex. This complexity can make NCD prevention strategies difficult to develop and implement. We therefore aimed to explore with key stakeholders the upstream policies needed to prevent NCDs and related inequalities. Methods: We developed a theory-based co-production process and used a mixed methods approach to engage with policy- and decision-makers from across the United Kingdom in a series of 4 workshops, to better understand and respond to the complex systems in which they act. The first and fourth workshops (London) aimed to better understand the public health policy agenda and effective methods for co-production, communication and dissemination. In workshops 2 and 3 (Liverpool and Glasgow), we used nominal group techniques to identify policy issues and equitable prevention strategies, we prioritised emerging policy options for NCD prevention, using the MoSCoW approach. Results: We engaged with 43 diverse stakeholders. They identified ‘healthy environment’ as an important emerging area. Reducing NCDs and inequalities was identified as important, underpinned by a frustration relating to the evidence/ policy gap. Evidence for NCD risk factor epidemiology was perceived as strong, the evidence underpinning the best NCD prevention policy interventions was considered patchier and more contested around the social, commercial and technological determinants of health. A comprehensive communications strategy was considered essential. The contribution of ‘elite actors’ (ministers, public sector leaders) was seen as key to the success of NCD prevention policies. Conclusions: NCDs are generated by complex adaptive systems. Early engagement of diverse stakeholders in a theory-based co-production process can provide valuable context and relevance. Subsequent partnership-working will then be essential to develop, disseminate and implement the most effective NCD prevention strategies

Modelling the UK burden of cardiovascular disease to 2020

This new research report demonstrates the scale of the burden of cardiovascular disease (CVD) - shown to be large, costly, and increasing. Whilst mortality from CVD has fallen, an increasing population over the next decade will create further demands on services as the actual numbers of people living with CVD climb higher.<br /
