A large cryptosporidiosis outbreak associated with an animal contact event in England: a retrospective cohort study, 2023.

Development of gastrointestinal illness after animal contact at petting farms is well described, as are factors such as handwashing and facility design that may modify transmission risk. However, further field evidence on other behaviours and interventions in the context of Cryptosporidium outbreaks linked to animal contact events is needed. Here, we describe a large outbreak of Cryptosporidium parvum (C. parvum) associated with a multi-day lamb petting event in the south-west of England in 2023 and present findings from a cohort study undertaken to investigate factors associated with illness. Detailed exposure questionnaires were distributed to email addresses of 647 single or multiple ticket bookings, and 157 complete responses were received. The outbreak investigation identified 23 laboratory-confirmed primary C. parvum cases. Separately, the cohort study identified 83 cases of cryptosporidiosis-like illness. Associations between illness and entering a lamb petting pen (compared to observing from outside the pen; odds ratio (OR) = 2.28, 95 per cent confidence interval (95% CI) 1.17 to 4.53) and self-reported awareness of diarrhoeal and vomiting disease transmission risk on farm sites at the time of visit (OR = 0.40, 95% CI 0.19 to 0.84) were observed. In a multivariable model adjusted for household clustering, awareness of disease transmission risk remained a significant protective factor (adjusted OR (aOR) = 0.07, 95% CI 0.01 to 0.78). The study demonstrates the likely under-ascertainment of cryptosporidiosis through laboratory surveillance and provides evidence of the impact that public health messaging could have.

Preliminary investigation of a significant national Cryptosporidium exceedance in the United Kingdom, August 2023 and ongoing.

Routine laboratory surveillance has identified an unprecedented and ongoing exceedance of Cryptosporidium spp. across the United Kingdom, notably driven by C. hominis transmission, since 14 August 2023. Information from 477 reported cases in England and Wales, followed up with a standardised exposure questionnaire as of 25 September 2023, identified foreign travel in 250 (54%) of 463 respondents and swimming in 234 (66%) of 353 cases. A significant, common exposure has not yet been identified in first analyses.

Saving the ground beneath our feet: Establishing priorities and criteria for governing soil use and protection.

The continual loss and impairment of soil ecosystem services (SES) across the globe calls for a fundamental reconsideration of soil governance mechanisms. This critical synthesis charts the history and evolution of national and international soil law and seeks to unravel certain challenges that have contributed to this failure in governance. It describes and categorizes law and policy responses to different soil threats, and identifies a worrying widespread absence of legislation for oversight and protection of agricultural soils from urbanization, as well as a lack of clear legal mechanisms to determine national priorities for soil protection. A reduction in the world's prime farmland threatens SES, including food security, carbon storage and biodiversity. Falling between the stalls of agricultural and environmental law, the fate of farmland is often left to planners who do not see themselves as responsible for soils. Consequently, legal instruments with the greatest power to affect soil, sometimes irreversibly, are often framed and worded with little or no reference to the soil. Nevertheless, emerging conceptual frameworks might offer positive outcomes. The authors advocate robust holistic policies of soil governance and land use planning that place SES and natural capital at the heart of decision making.

Analysis of the accuracy and completeness of cardiovascular health information on alcohol industry-funded websites.

BACKGROUND: The Alcohol Industry (AI), and the Social Aspects/Public Relations Organisations (SAPRO) it funds, has been shown to mis-represent the risk of alcohol with respect to cancer and pregnancy. It is theorized that the AI would position alcohol as 'heart healthy' to further undermine public perceptions of risks from drinking. METHODS: A comparative analysis (including content, thematic and context analyses) of cardiovascular health information published on the websites of AI-funded (n = 18, such as 'Drinkaware' and the 'Distilled Spirits Council of the US') and non-AI-funded (n = 18, such as 'NHS.uk') organizations based in multiple high-income jurisdictions. RESULTS: Websites of non-industry-funded health organizations were more likely than AI/SAPRO websites to label alcohol as a risk factor for a range of important cardiovascular diseases (such as myocardial infarction, congestive cardiac failure, hypertension and stroke). Conversely, AI/SAPRO websites were more likely to suggest alcohol was protective in the development of some heart conditions. AI/SAPRO websites frequently referenced the J-shaped curve as proof of benefit from moderate alcohol consumption; suggested a balance between the benefits and harms from drinking; positioned alcohol as consistent with a 'healthy lifestyle'; and framed drinking as a social norm. CONCLUSIONS: AI-funded health organizations mis-represent the evidence on cardiovascular effects of moderate alcohol consumption. Healthcare professionals should appreciate the role of funding source in biasing content, and exercise caution when directing patients to content funded by the AI. Tighter regulation of messaging that AI/SAPRO's provide to the public is required, to avoid the dissemination of harmful misinformation.

The Investigation and Management of Iliac Artery Endofibrosis: Lessons Learned from a Case Series.

OBJECTIVE/BACKGROUND: The objective was to summarise the lessons learned, and evolution in local practice over the last 7 years, in the investigation and surgical management of iliac artery endofibrosis. METHODS: This was a retrospective case series. A case note review of consecutive patients investigated for suspected iliac artery endofibrosis by a single surgeon, over a 7 year period, was undertaken. Included were cases of first presentation and those who had previously undergone intervention. RESULTS: Some 63 patients were referred with suspected endofibrosis in the period 2011-17, four of whom had previously undergone surgery for the condition. After investigation of both limbs, 50 symptomatic limbs in 46 patients had a confirmed diagnosis; amongst those 46 patients, iliac artery endofibrosis was found in a further six asymptomatic, contralateral limbs. Individuals were diagnosed at a median age of 36 years (range 18-52 years) and typically presented with thigh claudication, foot numbness, and limb weakness on exercise. The median delay to diagnosis was 3 years (range 0-14 years). Complete external iliac artery occlusion was a feature in three cases. Overall, 27 limbs in 25 patients underwent operative repair; a further five limbs in four patients underwent operative repair at other centres internationally. There were three post-operative superficial wound infections (11%) and one below knee deep vein thrombosis (4%). Symptoms resolved in 23 cases (85%) with a median follow up of 2.1 years (range 65 days-5.7 years). Of the four limbs developing recurrent symptoms, two had undergone surgery for an occluded external iliac artery. CONCLUSION: Surgical repair in the medium term appears effective in resolving symptoms in most patients. Further investigation is needed to establish the durability of surgery and to delineate the natural history of the disease.

Outcomes when congenital heart disease is diagnosed antenatally versus postnatally in the UK: a retrospective population-based study.

BACKGROUND: For major congenital heart disease, the benefits of antenatal diagnosis on some post-natal measures have been suggested. However, findings have been inconclusive and focus on short term outcome measures alone with little data from a UK population. Our aim is to describe differences in reported outcomes for patients born with isolated Hypoplastic Left Heart Syndrome or Transposition of the Great Arteries in a UK population, following either antenatal or postnatal diagnosis. METHODS: Retrospective population-based study with case note review covering a 15 year period (1st January 1998 to 31st December 2012) in the British county of Leicestershire. Cases were identified from two local registers: the East Midlands and South Yorkshire Congenital Anomaly Register and a list of surgical patient held by the East Midlands Congenital Heart Centre. RESULTS: In total 52 cases of Hypoplastic Left Heart Syndrome or Transposition of the Great Arteries were identified with 24 (46.2%) diagnosed antenatally. Maximum and minimum follow up was 181 and 16 months respectively. Median follow up was 83 months (IQR: 44-111). The risk of intubation in the postnatal period (OR: 4.64, 95% CI: 1.40 - 15.32) was greater in cases of Hypoplastic Left Heart Syndrome or Transposition of the Great Arteries diagnosed after birth when compared to those diagnosed antenatally. There was a non-significant increase in the risk of metabolic acidosis in the postnatal period (OR: 12.5, 95% CI: 0.64 - 245.46). No differences in mortality or long-term outcomes were demonstrated between antenatally and postnatally diagnosed cohorts. CONCLUSIONS: These results confirm data from American and European populations that, for a British population, an antenatal diagnosis of a major congenital heart disease can have a favourable impact on some postnatal outcome measures. There appears to be no evidence that time of diagnosis impacts on long-term outcome measures.
