Integrating Augmented In Situ Measurements and a Spatiotemporal Machine Learning Model To Back Extrapolate Historical Particulate Matter Pollution over the United Kingdom: 1980-2019

Historical PM2.5 data are essential for assessing the health effects of air pollution exposure across the life course or early life. However, a lack of high-quality data sources, such as satellite-based aerosol optical depth before 2000, has resulted in a gap in spatiotemporally resolved PM2.5 data for historical periods. Taking the United Kingdom as an example, we leveraged the light gradient boosting model to capture the spatiotemporal association between PM2.5 concentrations and multi-source geospatial predictors. Augmented PM2.5 from PM10 measurements expanded the spatiotemporal representativeness of the ground measurements. Observations before and after 2009 were used to train and test the models, respectively. Our model showed fair prediction accuracy from 2010 to 2019 [the ranges of coefficients of determination (R2) for the grid-based cross-validation are 0.71-0.85] and commendable back extrapolation performance from 1998 to 2009 (the ranges of R2 for the independent external testing are 0.32-0.65) at the daily level. The pollution episodes in the 1980s and pollution levels in the 1990s were also reproduced by our model. The 4-decade PM2.5 estimates demonstrated that most regions in England witnessed significant downward trends in PM2.5 pollution. The methods developed in this study are generalizable to other data-rich regions for historical air pollution exposure assessment.

Coordination of cybersecurity risk management in the U.K. insurance sector

The increasing threat of cyberattacks has resulted in increased efforts by both the U.K. government and regulatory authorities to coordinate efforts to influence cybersecurity risk management practices in the U.K. insurance sector, focusing on cyber risk underwriters. This paper provides an evaluation of these arrangements. It first provides a descriptive overview of the key U.K. regulatory authorities and the evolution of their efforts over the past decade, as well as the scope for broader collaborations with industry and member-based associations and international organisations. It then evaluates the effectiveness of these efforts by providing a multi-method study of the incidence, nature and evolution of cost of data breaches, investment in computer systems and software intangible assets at risk of cyberattack, and a content analysis of annual reports of both U.K. regulators and a sample of U.K. insurers. The findings suggest that while both the total costs of data breaches and the size of investment in computer systems and software intangibles at risk of cyberattack have gradually increased over time, the degree of engagement with cyber as a reporting issue by both cyber insurers and financial regulators has not. It is concluded that while these efforts have been apparently successful in avoiding a large-scale, systemic cyberattack on the U.K. insurance industry, there are significant gaps and overlaps in the system of cyber regulatory oversight.

Global health education in U.K. universities

Background

The coronavirus disease 2019 (COVID-19) pandemic has led to a paradigm shift in global health, casting a previously niche academic discipline into a headline dominating field of research. However, accurate information on the delivery of global health education (GHE) at a university level is lacking. This study aims to assess current GHE practices in U.K. universities, by identifying the availability of dedicated global health qualifications, as well as the breadth of inclusion of GHE topics across university course content.

Methods

Universities selected were the top 25 recipients of MRC funding in 2015–2016, as well as universities who were included in previous iterations of the “Global Health League Table”. We used the Consortium of Universities for Global Health “GHE Competencies Toolkit” to identify the presence of global health content across university global health and other course offerings. Universities were additionally judged on opportunities available in global health and on the presence of sustainable partnerships.

Results

Our results showed that 20 universities (74%) offer a post-graduate global health related course, with 9 (33%) offering an undergraduate global health related course. 13 (48%) were identified as centers of global health excellence. Just 12 (44%) universities had registered sustainable partnerships with Tropical Health and Education Trust. The London School of Hygiene and Tropical Medicine was identified as the top deliverer of GHE, with the Universities of Leicester and the Universities of Exeter joint bottom. We were unable to standardize quality assessments in this iteration of the project, but the release of student feedback to future assessors would help to improve the reliability of this study methodology. Additionally, much of our data was based on information available online, and thus some aspects of degree courses not published publicly may not have been accounted for in our scoring.

Conclusion

Those institutions wishing to improve their delivery of GHE should consider the establishment of a postgraduate or undergraduate degree course. Breadth of global health content across curricular was a major discriminating factor between institutions, and we would advise universities to consider including more global health topics across their curricular - especially in light of the intersectional impacts of the COVID-19 pandemic.

Coping strategies of individuals in the United Kingdom during the COVID-19 pandemic

The United Kingdom (UK) was among the hardest-hit by the COVID-19 pandemic. It is, therefore, imperative to understand the coping strategies of individuals in the UK during the pandemic to develop appropriate programs and policies for them. A heterogeneous sample of 50 UK residents (15 males & 35 females) with an age range of 18–55 years were recruited using a snowball technique from Facebook between April and May 2020. Participants responded to 4 open-ended questions (that were generated through consultation with literature and 2 health practitioners) that sought to explore their coping strategies during the COVID-19 pandemic. Thematic analysis was applied to analyze data using a data-driven method. Eleven themes were found: “socializing with loved ones (e.g., through video calls)”, “engaging in exercise”, “being occupied with jobs”, “being occupied with studies”, “avoiding negative news on COVID-19”, “consumption of alcohol”, “healthy eating”, “engaging in meditation activities”, “gaming activities”, “hope”, and “self-care and self-appreciation”, in that order. Positive and maladaptive coping strategies were employed by some individuals in the UK during the COVID-19 pandemic. This, therefore, echoes the need for appropriate psychosocial support programs that strengthen positive coping strategies and mitigate maladaptive coping strategies during the COVID-19 pandemic.

Role of Young Child Formulae and Supplements to Ensure Nutritional Adequacy in U.K. Young Children

The European Food Safety Authority (EFSA) states that young child formulae (YCFs) "cannot be considered as a necessity to satisfy the nutritional requirements" of children aged 12-36 months. This study quantifies the dietary changes needed to ensure nutritional adequacy in U.K. young children who consume YCFs and/or supplements and in those who do not. Dietary data from 1147 young children (aged 12-18 months) were used to identify, using linear programming models, the minimum changes needed to ensure nutritional adequacy: (i) by changing the quantities of foods initially consumed by each child (repertoire-foods); and (ii) by introducing new foods (non-repertoire-foods). Most of the children consumed neither YCFs, nor supplements (61.6%). Nutritional adequacy with repertoire-foods alone was ensured for only one child in this group, against 74.4% of the children consuming YCFs and supplement. When access to all foods was allowed, smaller food changes were required when YCFs and supplements were initially consumed than when they were not. In the total sample, the main dietary shifts needed to ensure nutritional adequacy were an increase in YCF and a decrease in cow's milk (+226 g/day and -181 g/day, respectively). Increasing YCF and supplement consumption was the shortest way to cover the EFSA nutrient requirements of U.K. children.

Occurrence and host preferences of Anopheles maculipennis group mosquitoes in England and Wales

Mosquitoes of the Anopheles maculipennis Meigen (Diptera: Culicidae) group are of public health concern: five of the 11 morphologically indistinct species have been historically considered as vectors of malaria in Europe. Three members of the An. maculipennis group have been reported in the U.K.: Anopheles atroparvus van Thiel; Anopheles messeae Falleroni, and Anopheles daciae Linton, Nicolescu & Harbach. To study the distribution of the three U.K. species, particularly that of An. daciae, we developed a polymerase chain reaction-Restriction fragment length polymorphism (PCR-RFLP) assay using the nuclear ribosomal internal transcribed spacer 2 (ITS-2) gene. Anopheles daciae was found to be widespread, occurring in four of the five counties surveyed in southern England and on the Welsh island of Anglesey, often in sympatry with the closely related species An. messeae. The host preferences of 237 blood-fed females were determined using either direct sequencing or PCR-based fragment analysis of the mitochondrial cytochrome oxidase b gene with DNA from females' abdomens. All three species were found to be opportunistic, having fed on at least three different hosts. Seventeen individuals contained multiple bloodmeals, including two An. daciae that had fed on humans and birds. Our results show that An. daciae is widespread in England and Wales, occurs in sympatry with other members of the An. maculipennis group, and feeds on humans, which suggests it is a potential vector of disease in the U.K.

Risk Assessment in the UK Health and Safety System: Theory and Practice

In the UK, a person or organisation that creates risk is required to manage and control that risk so that it is reduced 'So Far As Is Reasonably Practicable' (SFAIRP). How the risk is managed is to be determined by those who create the risk. They have a duty to demonstrate that they have taken action to ensure all risk is reduced SFAIRP and must have documentary evidence, for example a risk assessment or safety case, to prove that they manage the risks their activities create. The UK Health and Safety Executive (HSE) does not tell organisations how to manage the risks they create but does inspect the quality of risk identification and management. This paper gives a brief overview of where responsibility for occupational health and safety lies in the UK, and how risk should be managed through risk assessment. The focus of the paper is three recent major UK incidents, all involving fatalities, and all of which were wholly avoidable if risks had been properly assessed and managed. The paper concludes with an analysis of the common failings of risk assessments and key actions for improvement.

Urinary deoxynivalenol is correlated with cereal intake in individuals from the United kingdom

BACKGROUND

Deoxynivalenol (DON) is a toxic fungal metabolite that frequently contaminates cereal crops. DON is toxic to animals, but the effects on humans are poorly understood, in part because exposure estimates are of limited precision.

OBJECTIVES

In this study we used the U.K. adult National Diet and Nutrition Survey to compare 24-hr urinary DON excretion with cereal intake.

METHODS

One hundred subjects were identified for each of the following cereal consumption groups: low (mean, 107 g cereal/day; range, 88-125), medium (mean, 179 g/day; range, 162-195) and high (mean, 300 g/day; range, 276-325). DON was analyzed in 24-hr urine samples by liquid chromatography-mass spectrometry after purification on immunoaffinity columns.

RESULTS

DON was detected in 296 of 300 (98.7%) urine samples. Cereal intake was significantly associated with urinary DON (p < 0.0005), with the geometric mean urinary levels being 6.55 microg DON/day [95% confidence interval (CI), 5.71-7.53]; 9.63 microg/day (95% CI, 8.39-11.05); and 13.24 microg/day (95% CI, 11.54-15.19) for low-, medium-, and high-intake groups, respectively. In multivariable analysis, wholemeal bread (p < 0.0005), white bread (p < 0.0005), "other" bread (p < 0.0005), buns/cakes (p = 0.003), high-fiber breakfast cereal (p = 0.016), and pasta (p = 0.017) were significantly associated with urinary DON. Wholemeal bread was associated with the greatest percent increase in urinary DON per unit of consumption, but white bread contributed approximately twice as much as wholemeal bread to the urinary DON levels because it was consumed in higher amounts.

CONCLUSION

The majority of adults in the United Kingdom appear to be exposed to DON, and on the basis of the urinary levels, we estimate that some individuals may exceed the European Union (EU) recommended maximum tolerable daily intake of 1,000 ng DON/kg (bw). This exposure biomarker will be a valuable tool for biomonitoring as part of surveillance strategies and in etiologic studies of DON and human disease risk.
