RESUMO
Newcastle disease (ND) is a notifiable disease affecting chickens and other avian species caused by virulent strains of Avian paramyxovirus type 1 (APMV-1). While outbreaks of ND can have devastating consequences, avirulent strains of APMV-1 generally cause subclinical infections or mild disease. However, viruses can cause different levels of disease in different species and virulence can evolve following cross-species transmission events. This report describes the detection of three cases of avirulent APMV-1 infection in Great Britain (GB). Case 1 emerged from the 'testing to exclude' scheme in chickens in Shropshire while cases 2 and 3 were made directly from notifiable avian disease investigations in chicken broilers in Herefordshire and on premises in Wiltshire containing ducks and mixed species, respectively). Class II/genotype I.1.1 APMV-1 from case 1 shared 99.94% identity to the Queensland V4 strain of APMV-1. Class II/genotype II APMV-1 was detected from case 2 while the class II/genotype I.2 virus from case 3 aligned closely with strains isolated from Anseriformes. Exclusion of ND through rapid detection of avirulent APMV-1 is important where clinical signs caused by avirulent or virulent APMV-1s could be ambiguous. Understanding the diversity of APMV-1s circulating in GB is critical to understanding disease threat from these adaptable viruses.

Existing empirical work has focused on assessing the effectiveness of nonpharmaceutical interventions on human mobility to contain the spread of COVID-19. Less is known about the ways in which the COVID-19 pandemic has reshaped the spatial patterns of population movement within countries. Anecdotal evidence of an urban exodus from large cities to rural areas emerged during early phases of the pandemic across western societies. Yet, these claims have not been empirically assessed. Traditional data sources, such as censuses offer coarse temporal frequency to analyse population movement over infrequent time intervals. Drawing on a data set of 21 million observations from Meta-Facebook users, we aim to analyse the extent and evolution of changes in the spatial patterns of population movement across the rural-urban continuum in Britain over an 18-month period from March 2020 to August 2021. Our findings show an overall and sustained decline in population movement during periods of high stringency measures, with the most densely populated areas reporting the largest reductions. During these periods, we also find evidence of higher-than-average mobility from high-density population areas to low-density areas, lending some support to claims of large-scale population movements from large cities. Yet, we show that these trends were temporary. Overall mobility levels trended back to precoronavirus levels after the easing of nonpharmaceutical interventions. Following these interventions, we found a reduction in movement to low-density areas and a rise in mobility to high-density agglomerations. Overall, these findings reveal that while COVID-19 generated shock waves leading to temporary changes in the patterns of population movement in Britain, the resulting vibrations have not significantly reshaped the prevalent structures in the national pattern of population movement. As of 2021, internal population movements sit at an intermediate level between those observed pre- and early phases of the pandemic.
RESUMO
With international health challenges, there are opportunities for collaboration between nations on health issues, including developing and sharing resources for teaching and learning. This article outlines collaboration across Scotland and England to develop a core resource for eLearning on health literacy. It describes the development of the resource with case studies of the implementation in Scotland and England, demonstrating the balance between shared development and tailored implementation. The eLearning was developed to increase awareness of NHS workforce and community partners, supplemented by training for NHS librarians and public health specialists to enable them to provide more tailored training on health literacy techniques.

BACKGROUND: Satisfaction with dental services can provide valuable insights into aspects of quality including access as well as changes in this over time. In the UK publicly funded dental services are ostensibly delivered by private sector general dental practitioners for whom private patients represent an opportunity cost to the provision of care to public patients. This study examined changes in satisfaction as economic circumstances and policy changed in Britain between 1998 and 2019. METHODS: Data were taken from successive waves of the British Social Attitudes Survey a representative cross-sectional survey of the population between 1998 and 2019. Descriptive statistics and a series of logistic regression analyses were used to examine the relationships between satisfaction and a range of socio-demographic characteristics over time. RESULTS: 37,328 usable responses were extracted from the survey spanning 21 years of data. Over the course of the survey approximately 71% of the sample was very satisfied, satisfied or neither satisfied nor dissatisfied with publicly funded dental services. Satisfaction fell at the outset of the study period but rose following the economic downturn from 2008 which coincided with increased use of publicly funded services. Differences were evident in satisfaction between older versus younger respondents, more affluent versus less affluent respondents and better educated versus less well-educated respondents. Satisfaction did not appear to change in response to policy changes. CONCLUSION: Satisfaction is an important outcome of service provision. Policies aiming to improve satisfaction with publicly funded dental care in the UK must take account of the competing demands on dentists' time from private patients. At times of economic expansion or when supply has been disrupted, these may be particularly acute and require specific interventions to improve access for those who depend on public services.

This study extends our understanding of the influence of proximity to retail grocery provision on housing rental prices. To achieve this, extensive data on the size and location of retail outlets are combined with neighbourhood rental values for small areas across a two year period, together with varied contextual data for each area. In order to control the influence of many confounding variables in the determination of housing rentals, the technique of propensity score matching is applied. This provides a sophisticated means for the comparison between areas where there is substantial natural variation, rather than manageable controls. For a variety of types of retail brands, only a significant relationship is found between the proximity of a Premium retail outlet and the housing rental value. The findings of this research allow local planning officers to further understand the impact of planning applications on the potential for gentrification and the affordability of neighbouring housing. Supplementary Information: The online version contains supplementary material available at 10.1007/s10901-021-09904-2.
RESUMO
Pharmacovigilance is an integral part of medicine. There is always a risk of side effects when using medication; these can be completely trivial, but there are side effects that can be life-threatening or fatal. Pharmacovigilance practices should prevent such side effects, or at least reduce their incidence, especially by developing preventive measures that are based on adverse drug reaction (ADR) data and the evaluations of these. This article discusses the general concept of pharmacovigilance and compares individual pharmacovigilance systems of several countries and regions.

This paper establishes a unified framework to fully account for the changing social gradient over the lifecycle in terms of a sufficient set of mobility indices characterizing the coevolution of socioeconomic status and health within each of a series of overlapping cohorts. We proceed to demonstrate the impact of selective mortality on health inequality changes, making use of a counterfactual health distribution for the start of the study period that leaves out those who are known to die before the end. Specifically, initial differences between the average health and educational attainment rank of survivors and nonsurvivors are found in our empirical study to be an increasingly important factor explaining changes in the education-health gradient in older cohorts in Great Britain. Our identification strategy has the advantage that it does not require the imputation of the "would be" health of nonsurvivors, which if carried out using inverse probability weighting procedures-as in several previous studies-is shown to bias estimates of this direct effect of selective mortality toward zero. Parallel results for the income-health gradient exhibit stronger confounding influences due to a number of other factors given that income is a less stable indicator of socioeconomic status in adulthood.

OBJECTIVE: Most research investigating sugar-sweetened beverages (SSB) and health, conducted at the individual or household level, ignores potentially important intra-household dynamics. We analysed self-reported consumption relationships between children and adults, and between children of different ages, as well as the associations between intra-household consumption, BMI and sociodemographic characteristics. DESIGN: A cross-sectional analysis of survey data from Kantar Fast Moving Consumer Goods panellists in September 2017. SETTING: Great Britain. PARTICIPANTS: Random sample of 603 households with children under 18 years who regularly purchase non-alcoholic beverages. RESULTS: Low- or no-sugar/diet beverages dominate consumption across all age categories, particularly children under 12 years. SSB consumption increased as children became older. Children's reported consumption of SSB and low- or no-sugar/diet beverages was positively associated with consumption by adults; a child in adolescence had over nine times the odds of consuming SSB (adjusted OR 9·55, (95 % CI 5·38, 17·00), P < 0·001), and eight times the odds of consuming low- or no-sugar/diet drinks (adjusted OR 8·12, (95 % CI 4·71, 13·97), P < 0·001), if adults did so. In households with multiple children, consumption patterns of older siblings were associated with those of the younger; notably a perfect correlation between children aged 0 and 6 years consuming SSB if siblings 13-18 years did so, and children aged 7-12 years had 22 times the odds of consuming SSB if siblings aged 13-18 years did so (OR 22·33, (95 % CI 8·60, 58·01), P < 0·001). CONCLUSIONS: Multiple policies, targeting children as well as adults, such as fiscal levers and advertisement restrictions, are needed to reduce and prevent the consumption of SSB.
RESUMO
The nineteenth century witnessed a great shift in how insanity was regarded and treated. Well documented is the emergence of psychiatry as a medical specialization and the role of lunatic asylums in the West. Unclear are the relationships between the heads of institutions and the individuals treated within them. This article uses two cases at either end of the nineteenth century to demonstrate sexual misdemeanours in sites of mental health care, and particularly how they were dealt with, both legally and in the press. They illustrate issues around cultures of complaint and the consequences of these for medical careers. Far from being representative, they highlight the need for further research into the doctor-patient relationship within asylums, and what happened when the boundaries were blurred.

BACKGROUND: Clinical cases of Erysipelothrix rhusiopathiae, a zoonotic gram-positive bacterium, have been reported in many ruminant species, including in cattle, deer, moose and muskoxen. Fatal cases have been repeatedly reported in cattle over the years but to date there is only one Japanese study investigating the seroprevalence of this bacterium in cattle using the growth agglutination test (GAT). This technique is subjective, time-consuming, expensive and hazardous compared to modern serological tests such as enzyme-linked immunosorbent assays (ELISA) or the newly developed fluorescent microbead-based immunoassays (FMIA). RESULTS: The FMIA based on the surface protein SpaA (rSpaA415) antigen of E. rhusiopathiae developed in this study had an almost perfect agreement with the GAT (k = 0.83) and showed a sensitivity of 89.7% and a specificity of 92.9% when compared to the GAT. Overall, detection rates of E. rhusiopathiae antibody positive samples were 13.8% (51/370) in British herds and 6% (12/200) in US herds. Positive cattle were present in 34.3% (24/70) of the investigated British farms and in 34.7% (8/23) of the US farms with an on-farm prevalence of 7.1 to 100% for the British farms and 8.3-30% for the US farms. CONCLUSIONS: FMIA is a fast, safe and economic alternative to the GAT for the diagnosis of E. rhusiopathiae in cattle. This work is the first seroprevalence study of E. rhusiopathiae in healthy farmed cattle in Great Britain and the US and revealed that infection occurs at a low level. Further investigations to evaluate risks of zoonotic transmission when handling cattle are needed.

Dr Edward Sumner (1940) enjoyed a remarkably productive career as consultant pediatric anesthetist at the Great Ormond Street Hospital for Children. His leadership in clinical care helped his department rise to eminence. He trained hundreds of registrars in pediatric anesthesia and educated thousands more through invited lectures and by co-editing leading textbooks of neonatal and pediatric anesthesia. During his long tenure as Editor-in-Chief of Pediatric Anesthesia, he led the growth of the young journal to prominence. Based on an interview and a long-standing professional and personal friendship of forty-four years, this article reviews Ted Sumner's outstanding contributions to the specialty of pediatric anesthesia and to the development of a strong international community of pediatric anesthesiologists.

BACKGROUND: The authors developed a validated geographic search filter to retrieve research about the United Kingdom (UK) from OVID Embase. It was created to be used alongside their previously published OVID MEDLINE UK filter in systematic literature searches for context-sensitive topics. OBJECTIVES: To develop a validated geographic search filter to retrieve research about the UK from OVID Embase. METHODS: The Embase UK filter was translated from the MEDLINE UK filter. A gold standard set of references was generated using the relative recall method. The set contained references to publications about the UK that had informed National Institute for Health and Care Excellence (NICE) guidance and it was used to validate the filter. Recall, precision and number-needed-to-read (NNR) were calculated using a case study. RESULTS: The validated Embase UK filter demonstrated 99.8% recall against the references with UK identifiers in the gold standard set. In the case study, the Embase UK filter demonstrated 98.5% recall, 7.6% precision and a NNR of 13. CONCLUSION: The Embase UK filter can be used alongside the MEDLINE UK filter. The filters have the potential to save time and associated resource costs when they are used for context-sensitive topics that require research about UK settings.

This essay examines the reception of Ivan Pavlov's work on conditioned reflexes in early to mid-twentieth century Britain. Recent work on the political interpretation of biology has shown that the nineteenth-century strategy of "making socialists" was undermined by August Weismann's attacks on the inheritance of acquired characters. I argue that Pavlov's research reinvigorated socialist hopes of transforming society and the people in it. I highlight the work of Pavlov's interpreters, notably the scientific journalist J. G. Crowther, the biologist Lancelot Hogben, and the science writer H. G. Wells, who made Pavlov's work accessible to a British audience and embraced the socialist implications of his research - especially the idea that people could be persuaded to become socialists through science writing for a nonspecialist audience and through use of a simplified language such as Basic English. They saw, in the followers of National Socialism, how Pavlovian conditioning could create a national movement, and believed that this could be used for their own more democratic form of socialism. In the final part of the essay, I suggest that this broad socio-cultural movement to reshape humanity proved controversial, especially in the post-war period and in light of Soviet use of brainwashing. The likes of Aldous Huxley and F. A. Hayek feared that conditioning could only lead to totalitarianism, while the historian E. P. Thompson put forward a socialist humanism that left room for human agency.
RESUMO
Distinctions between internal migration and residential mobility are often formed with reference to assumed differences in motivation, with migration typically linked to employment and educational motives and shorter distance mobility to housing and family. Using geocoded microdata, this article reveals how employment-led migration represents only a minority share (≈30%) of total migration events over 40 km. Family motives appear just as important, even at distances ≥100 km, with the desire to live closer to non-resident family/friends being the most frequently cited family submotive. Estimated propensities to undertake employment and educational-related migration fit very closely to predictions of human capital models of migration, being highest among young, residentially flexible and highly educated individuals. Migrants citing family-related motives are disproportionately drawn from midlife and later-life phases, with family shown to be a key motive among migrants with care-related needs (e.g., parents with children) or access to fewer resources (e.g., social renters and low educational attainment).
RESUMO
In this retrospective study, we describe and analyse Salmonella data from four livestock species in Great Britain between 1983 and 2014, focusing on Salmonella Typhimurium. A total of 96 044 Salmonella isolates were obtained during the study period. S. Typhimurium was the predominant serovar isolated from cattle and pigs and represented 40.7% (18 455/45 336) and 58.3% (4495/7709) of isolates from these species respectively, while it only accounted for 6.7% (2114/31 492) of chicken isolates and 8.1% (926/11 507) of turkey isolates. Over the study period, DT104 was the most common phage type in all four species; however, DT104 peaked in occurrence between 1995 and 1999, but is currently rare. Monophasic strains of S. Typhimurium represented less than 3% of all Salmonella isolates in cattle and chickens in 2014, but accounted for 10.4% of all turkey isolates and 39.0% of all pig isolates in the same year. Salmonella isolates were tested for their in vitro susceptibility to 16 antimicrobials. Antimicrobial resistance of S. Typhimurium isolates is largely influenced by the dominance of specific phage types at a certain time, which are commonly associated with particular resistance patterns. Changes in resistance patterns over time were analysed and compared between species.

Infectious disease is a significant driver of global amphibian declines, yet despite this, relatively little is known about the range of pathogens that affect free-living amphibians. Recent detection of the tentatively named Ranid herpesvirus 3 (RHV3), associated with skin disease in free-living common frogs Rana temporaria in Switzerland, helps to address this paucity in knowledge, but the geographic distribution and epidemiology of the pathogen remains unclear. Syndromic surveillance for ranid herpesvirus skin disease was undertaken throughout Great Britain (GB), January 2014 to December 2016. Reports of common frogs with macroscopic skin lesions with a characteristic grey appearance were solicited from members of the public. Post-mortem examination was conducted on one affected frog found dead in 2015 at a site in England. In addition, archived samples from an incident involving common frogs in England in 1997 with similar macroscopic lesions were further investigated. Transmission electron microscopy identified herpes-like virions in skin lesions from both the 1997 and 2015 incidents. RHV3, or RHV3-like virus, was detected in skin lesions from the 2015 case by PCR and sequencing. Our findings indicate that herpesvirus skin disease is endemic in common frogs in GB, with widespread distribution at apparently low prevalence. Further research into the role of host immunity, virus latency and the significance of infection to host survival is required to better understand the epidemiology and impact of cutaneous herpesvirus infections in amphibian populations.

BACKGROUND: Despite Britain, Colombia, and some Mexican states sharing a health exception within their abortion laws, access to abortion under the health exception varies widely. This study examines factors that result in heterogeneous application of similar health exception laws and consequences for access to legal abortion. Our research adds to previous literature by comparing implementation of similar abortion laws across countries to identify strategies for full implementation of the health exception. METHODS: We conducted a cross-country comparative descriptive study synthesizing data from document and literature review, official abortion statistics, and interviews with key informants. We gathered information on the use and interpretation of the health exception in the three countries from peer-reviewed literature, court documents, and grey literature. We next extracted public and private abortion statistics to understand the application of the law in each setting. We used a matrix to synthesize information and identify key factors in the use of the law. We conducted in-depth interviews with doctors and experts familiar with the health exception laws in each country and analyzed the qualitative data based on the previously identified factors. RESULTS: The health exception is used broadly in Britain, somewhat in Colombia, and very rarely in Mexican states. We identified five factors as particularly salient to application of the health exception in each setting: 1) comprehensiveness of the law including explicit mention of mental health, 2) a strong public health sector that funds abortion, 3) knowledge of and attitudes toward the health exception law, including guidelines for physicians in providing abortion, 4) dissemination of information about the health exception law, and 5) a history of court cases that protect women and clarify the health exception law. CONCLUSIONS: The health exception is a valuable tool for expanding access to legal abortion. Differences in the use of the health exception as an indication for legal abortion result in wide access for women in Britain to nearly no access in Mexican states. Our findings highlight the difference between theoretical and real access to legal abortion. The interpretation and application of the health exception law are pivotal to expanding real access to abortion.

Using detailed geocoded microdata from the British Household Panel Survey and longitudinal random-effects models, we analyse the determinants and trajectories of geographical distances between separated parents. Findings of particular note include the following: (1) post-separation linked lives, proximities and spatial constraints are characterised by important gender asymmetries; (2) the formation of new post-separation family ties (i.e. new partners and children) by fathers is linked to moves over longer distances away from the ex-partner than for mothers; (3) the distribution of pre-separation childcare responsibilities is relevant for determining post-separation proximity between parents; and (4) most variation in the distance between ex-partners occurs in the immediate period following separation (approximately the first year), suggesting that the initial conditions around separation can have long-lasting implications for the types of family life, ties and contact experienced in the years after separation.
RESUMO
The objective of the present work was to study the specific approaches to the organization of the work of the foreign specialists performing post-mortem autopsies of the subjects who died from infectious pathology and consider the proposals of the representatives of the National Confidential Enquiry into Patient Outcome and Death (NCEPOD) concerning accreditation of mortuaries in the Great Britain. It is shown that the algorithm for the evaluation of the possible risks of contamination of the medical personnel suggests the solution of five problems that envisages obtaining the answers to the following questions: (1) what biological agents can be present in a particular case? (2) what is their virulence factor? (3) what are the transmission routes (mechanisms)? (4) what are the manner of their realization? (5) what is the amount of the pathogen(s) needed to cause a given infectious disease? The anti-infectious prophylactic measures and the prevention of the contamination risks for the medical personnel of the British mortuaries are designed to safeguard the people against the infection with the causative agents of tuberculosis, viral hepatitis B and C, HIV, and Kreutsfield- Jacob's disease. All the employees engaged in the pathological studies must wear specialized clothing in a mandatory manner and make use of the equipment for the personal and collective protection. An indispensable condition for the safe work in a mortuary is the efficient ventilation system, the special viewing equipment, and separate premises. The NCEPOD experts maintain that the general approach to the investigations of the cases of infectious diseases presently adopted in the country needs to be radically re-considered and standardized. Diagnostics of contamination and morbidity of the medical personnel from the corpses has not yet become a routine practice. The principal recommendation to be implemented at the national level consists of the strict observance of the safety precautions as opposed to the total pre-mortem testing of the suspicious cases.

Comparability of population surveys across countries is key to appraising trends in population health. Achieving this requires deep understanding of the methods used in these surveys to examine the extent to which the measurements are comparable. In this study, we obtained detailed protocols of 8 nationally representative surveys from 2007-2013 from Brazil, Chile, Colombia, Mexico, the United Kingdom (England and Scotland), and the United States-countries that that differ in economic and inequity indicators. Data were collected on sampling frame, sample selection procedures, recruitment, data collection methods, content of interview and examination modules, and measurement protocols. We also assessed their adherence to the World Health Organization's "STEPwise Approach to Surveillance" framework for population health surveys. The surveys, which included half a million participants, were highly comparable on sampling methodology, survey questions, and anthropometric measurements. Heterogeneity was found for physical activity questionnaires and biological samples collection. The common age range included by the surveys was adults aged 18-64 years. The methods used in these surveys were similar enough to enable comparative analyses of the data across the 7 countries. This comparability is crucial in assessing and comparing national and subgroup population health, and to assisting the transfer of research and policy knowledge across countries.
