Currently, there are two recognised genotypes of Bovine viral diarrhoea virus (BVDV), type 1 and type 2. These genotypes are divided into subtypes based on phylogenetic analysis, namely a-p for BVDV-1 and a-c for BVDV-2. Within this study, the genetic heterogeneity of BVDV-1 in England and Wales was investigated and compared to the situation in 1996/1997. Viral RNA was extracted from 316 blood samples collected between 2004 and 2009 that were previously identified as BVDV-1 positive. A region of the 5' untranslated region (UTR) was amplified by RT-PCR and the PCR products were sequenced. Phylogenetic analysis of the 5'UTR demonstrated the existence of five subtypes of BVDV-1 circulating in England and Wales, namely BVDV-1a (244 samples), BVDV-1b (50), BVDV-1e (3), BVDV-1f (1) and BVDV-1i (18). Phylogenetic analysis of the nucleotide sequence for the N(pro) region of the viral genome supported the classification obtained with the 5'UTR. Given the fact that only three subtypes were detected in 1999 this report supports the notion that the restocking of cattle from continental Europe, after the mass culling during the Foot-and-Mouth outbreak in 2001 and slaughter of cattle due to bovine tuberculosis infection, has increased the genetic diversity of BVDV-1 subtypes in England and Wales in the past 10 years.

Identifying Key Weather Factors Influencing Human Salmonellosis: A Conditional Incidence Analysis in England, Wales, and the Netherlands.

Objectives: This study aimed to improve the understanding of seasonal incidence pattern observed in salmonellosis by identifying the most influential weather factors, characterizing the nature of this association, and assessing whether it is geographically restricted or generalizable to other locations.
Methods: A novel statistical model was employed to estimate the incidence of salmonellosis conditional to various combinations of three simultaneous weather factors from 14 available. The analysis utilised daily salmonellosis cases reported from 2000 to 2016 along with detailed spatial and temporal weather data from England and Wales, and the Netherlands.

Background: Our aim was to determine the impact of the COVID-19 pandemic on the publication productivity of neurosurgeons in the United Kingdom and Republic of Ireland.
Methods: Using bibliometric data we quantified and analysed the academic output of neurosurgeons in England, Scotland, Northern Ireland, Wales, and the Republic of Ireland, between two time periods i.e.
Patient and public involvement in the design and protocol development for a platform randomised trial to evaluate diagnostic tests to optimise antimicrobial therapy (PROTECT).
NIHR Open Res
September 2024
Centre for Trials Research, Cardiff University, Cardiff, Wales, CF14 4YS, UK.
Background: Our patient and public involvement activities were part of a project aiming to develop a master protocol and National Institute for Health and Care research application for the PROTECT trial aiming to assess the effectiveness, implementation, and efficiency of antimicrobial stewardship interventions, to safely reduce unnecessary antibiotic usage by excluding severe bacterial infection in acutely unwell patients.
Methods: Three public involvement sessions were held with representation from young people and parents, people from diverse backgrounds and people with experience of presenting to the emergency department with undifferentiated illness. The teleconference meetings lasted between 60-90 minutes, were recorded, notes were subsequently taken, and findings summarised.
Large-scale and long-term wildlife research and monitoring using camera traps: a continental synthesis.

Camera traps are widely used in wildlife research and monitoring, so it is imperative to understand their strengths, limitations, and potential for increasing impact. We investigated a decade of use of wildlife cameras (2012-2022) with a case study on Australian terrestrial vertebrates using a multifaceted approach. We (i) synthesised information from a literature review; (ii) conducted an online questionnaire of 132 professionals; (iii) hosted an in-person workshop of 28 leading experts representing academia, non-governmental organisations (NGOs), and government; and (iv) mapped camera trap usage based on all sources.

Background: Public health nutrition interventions, including school-based programs, are a recommended approach to improve child dietary behaviours. However, the adoption of effective school-based nutrition programs face numerous challenges, including the limited evidence on effective strategies to maximise implementation and adoption of such programs. This study aimed to address this evidence gap by employing a novel collaborative network trial design to evaluate a series of implementation strategies employed by three NSW Local Health Districts, to improve school adoption of an effective school-based nutrition program ('SWAP IT').
