Implementation of the European legislation to protect farm animals: a case-study on French inspections to find solutions to improve compliance

In the European Union, at least 1% of farms are inspected every year and sanctions are applied to those that do not comply with the legislation on animal welfare. These on-farm inspections can result in measures to correct welfare problems detected. They can also highlight major risks that will require a focus of efforts and help prevent further non-compliances. Here, we analysed the reports from inspections of French cattle farms between 2010 and 2013 to check whether inspection stimulates improvement and to propose ways to improve how animal welfare legislation is implemented through the cross-compliance system. French inspectors use 32 items to assess overall compliance of farms inspected. We found that compliance improves on farms that are re-inspected but not in other farms (8% of severely non-compliant farms). Nine items do not influence the overall assessment whereas eight have a huge impact. The importance attributed to items varies from the first to the second visit to a farm. The major risks are absence of farm records, lack of basic care (practices or enclosures likely to harm animals, insufficient feeding) and inadequate skills (no veterinarian consulted, insufficient qualified staff). To improve compliance with EU animal welfare legislation and the efficiency of the inspection system, we suggest organising consultation between inspectors, ministry central services and welfare experts to: (i) refine the checklist and harmonise interpretations of item compliance; (ii) make sure all farmers are aware of the legislative requirements and the major risks of non-compliance; and (iii) define plans for a step-wise improvement of non-compliant farms

Parents' and guardians' views on the acceptability of a future COVID-19 vaccine: A multi-methods study in England.

BACKGROUND: The availability of a COVID-19 vaccine has been heralded as key to controlling the COVID-19 pandemic. COVID-19 vaccination programme success will rely on public willingness to be vaccinated. METHODS: We used a multi-methods approach - involving an online cross-sectional survey and semi-structured interviews - to investigate parents' and guardians' views on the acceptability of a future COVID-19 vaccine. 1252 parents and guardians (aged 16 + years) who reported living in England with a child aged 18 months or under completed the survey. Nineteen survey participants were interviewed. FINDINGS: Most survey participants reported they would likely accept a COVID-19 vaccine for themselves (Definitely 55.8%; Unsure but leaning towards yes 34.3%) and their child/children (Definitely 48.2%; Unsure but leaning towards yes 40.9%). Less than 4% of survey participants reported that they would definitely not accept a COVID-19 vaccine. Survey participants were more likely to accept a COVID-19 vaccine for themselves than their child/children. Participants that self-reported as Black, Asian, Chinese, Mixed or Other ethnicity were almost 3 times more likely to reject a COVID-19 vaccine for themselves and their children than White British, White Irish and White Other participants. Survey participants from lower-income households were also more likely to reject a COVID-19 vaccine. In open-text survey responses and interviews, self-protection from COVID-19 was reported as the main reason for vaccine acceptance. Common concerns identified in open-text responses and interviews were around COVID-19 vaccine safety and effectiveness, mostly prompted by the newness and rapid development of the vaccine. CONCLUSION: Information on how COVID-19 vaccines are developed and tested, including their safety and efficacy, must be communicated clearly to the public. To prevent inequalities in uptake, it is crucial to understand and address factors that may affect COVID-19 vaccine acceptability in ethnic minority and lower-income groups who are disproportionately affected by COVID-19

Pollution des eaux superficielles et des nappes en milieu urbain : cas de la zone industrielle de Douala-Bassa (Cameroun)

Une étude a été menée dans la zone industrielle de Douala-Bassa afin d'évaluer l'ampleur de la pollution des cours d'eau et des nappes superficielles et de prédire la vulnérabilité de ces dernières. L'étude est basée sur l'analyse des eaux issues de deux campagnes de terrain portant chacune sur 7 prélèvements dans les eaux de surface et 8 dans les eaux souterraines. Outre les analyses physico-chimiques de base, la particularité de l'étude a porté sur la caractérisation de la matière organique et la dynamique de métaux lourds, notamment le plomb, lenickel et le cuivre. Les résultats montrent que les eaux de surface sont neutres (pH 6,2), peu minéralisées (conductivité moyenne 262 mS/cm) et peu turbides (7 NTU) à l'amont. Elles s'enrichissent ensuite dans leréseau où elles deviennent acides (pH 5,8), plus minéralisées (623 à 818 mS/cm) suite aux apports générés par les activités industrielles et domestiques. Les eaux de surface sont polluées (carbonique organique total, 13,0 mg/l ; turbidité 168 NTU). Une source potentielle de pollution au nickel et en matière organique est observée dans les eaux souterraines qui compromet l'exploitation durable de cette ressource en eau

Women’s views on accepting COVID-19 vaccination during and after pregnancy, and for their babies: A multi-methods study in the UK.

Background: COVID-19 vaccines are advised for pregnant women in the United Kingdom (UK) however COVID-19 vaccine uptake among pregnant women is inadequate. Methods: An online survey and semi-structured interviews were used to investigate pregnant women’s views on COVID-19 vaccine acceptability for themselves when pregnant, not pregnant and for their babies. 1,181 women, aged over 16 years, who had been pregnant since 23rd March 2020, were surveyed between 3rd August–11th October 2020. Ten women were interviewed. Results: The majority of women surveyed (81.2%) reported that they would ‘definitely’ or were ‘leaning towards’ accepting a COVID-19 vaccine when not pregnant. COVID-19 vaccine acceptance was significantly lower during pregnancy (62.1%, p<0.005) and for their babies (69.9%, p<0.005). Ethnic minority women were twice as likely to reject a COVID-19 vaccine for themselves when not pregnant, pregnant and for their babies compared to women from White ethnic groups (p<0.005). Women from lower-income households, aged under 25-years, and from some geographic regions were more likely to reject a COVID-19 vaccine when not pregnant, pregnant and for their babies. Multivariate analysis revealed that income and ethnicity were the main drivers of the observed age and regional differences. Women unvaccinated against pertussis in pregnancy were over four times more likely to reject COVID-19 vaccines when not pregnant, pregnant and for their babies. Thematic analysis of the survey freetext responses and interviews found safety concerns about COVID-19 vaccines were common though wider mistrust in vaccines was also expressed. Trust in vaccines and the health system were also reasons women gave for accepting COVID-19 vaccines. Conclusion: Safety information on COVID-19 vaccines must be clearly communicated to pregnant women to provide reassurance and facilitate informed pregnancy vaccine decisions. Targeted interventions to promote COVID-19 vaccine uptake among ethnic minority and lower-income women may be needed

Co-production of an educational package for the universal human papillomavirus (HPV) vaccination programme tailored for schools with low uptake:A participatory study protocol

AIM: To co-produce with young people an educational package about the human papillomavirus (HPV) vaccine that is tailored to increase vaccine uptake in schools and populations with lower uptake. INTRODUCTION: Persistent infection with HPV can result in cancers affecting men and especially women. From September 2019, the English-schools-based HPV vaccination programme was expanded to include young men (in addition to young women) aged 12-13 years. Some young people attending schools with lower uptake of the vaccine have unmet information needs. We hypothesise that mechanisms to address information needs and increase young people's autonomy in consent procedures will result in higher uptake. METHODS AND ANALYSIS: The Medical Research Council's framework for development and evaluation of complex interventions will inform intervention development. Recruitment of young people aged 12-15 years and key stakeholders (National Health Service commissioners, school staff, immunisation nurses and youth workers/practitioners) will be facilitated through existing links with healthcare organisations, schools and youth organisations in areas with lower uptake of the HPV vaccination programme. The proposed research will comprise three phases: (1) a rapid review of adolescent immunisation materials and preliminary qualitative interviews with young people and key stakeholders, (2) theory development and co-production of HPV vaccine communication materials through an iterative process with young people and (iii) testing delivery mechanisms and acceptability of the educational package in four schools with lower uptake. ETHICS AND DISSEMINATION: The University of Bristol's Faculty of Health Sciences and London School of Hygiene and Tropical Medicine's Research Ethics Committees provided approvals for the study. A dissemination event for young people and key stakeholders and webinar with the National Immunisation Network will be organised. The study findings will be published in peer-reviewed journals and presented at conferences. Recommendations for a future larger scale study will be made

Pandemic influenza preparedness and health systems challenges in Asia: results from rapid analyses in 6 Asian countries

BACKGROUND: Since 2003, Asia-Pacific, particularly Southeast Asia, has received substantial attention because of the anticipation that it could be the epicentre of the next pandemic. There has been active investment but earlier review of pandemic preparedness plans in the region reveals that the translation of these strategic plans into operational plans is still lacking in some countries particularly those with low resources. The objective of this study is to understand the pandemic preparedness programmes, the health systems context, and challenges and constraints specific to the six Asian countries namely Cambodia, Indonesia, Lao PDR, Taiwan, Thailand, and Viet Nam in the prepandemic phase before the start of H1N1/2009. METHODS: The study relied on the Systemic Rapid Assessment (SYSRA) toolkit, which evaluates priority disease programmes by taking into account the programmes, the general health system, and the wider socio-cultural and political context. The components under review were: external context; stewardship and organisational arrangements; financing, resource generation and allocation; healthcare provision; and information systems. Qualitative and quantitative data were collected in the second half of 2008 based on a review of published data and interviews with key informants, exploring past and current patterns of health programme and pandemic response. RESULTS: The study shows that health systems in the six countries varied in regard to the epidemiological context, health care financing, and health service provision patterns. For pandemic preparation, all six countries have developed national governance on pandemic preparedness as well as national pandemic influenza preparedness plans and Avian and Human Influenza (AHI) response plans. However, the governance arrangements and the nature of the plans differed. In the five developing countries, the focus was on surveillance and rapid containment of poultry related transmission while preparation for later pandemic stages was limited. The interfaces and linkages between health system contexts and pandemic preparedness programmes in these countries were explored. CONCLUSION: Health system context influences how the six countries have been preparing themselves for a pandemic. At the same time, investment in pandemic preparation in the six Asian countries has contributed to improvement in health system surveillance, laboratory capacity, monitoring and evaluation and public communications. A number of suggestions for improvement were presented to strengthen the pandemic preparation and mitigation as well as to overcome some of the underlying health system constraints

Direct Observation of Propagating Gigahertz Coherent Guided Acoustic Phonons in Free Standing Single Copper Nanowires

We report on gigahertz acoustic phonon waveguiding in free-standing single copper nanowires studied by femtosecond transient reflectivity measurements. The results are discussed on the basis of the semianalytical resolution of the Pochhammer and Chree equation. The spreading of the generated Gaussian wave packet of two different modes is derived analytically and compared with the observed oscillations of the sample reflectivity. These experiments provide a unique way to independently obtain geometrical and material characterization. This direct observation of coherent guided acoustic phonons in a single nano-object is also the first step toward nanolateral size acoustic transducer and comprehensive studies of the thermal properties of nanowires

Optimization and evaluation of a non-invasive tool for peste des petits ruminants surveillance and control

Peste des petits ruminants (PPR) is a highly contagious and devastating viral disease affecting mainly sheep and goats, but also a large number of wild species within the order Artiodactyla. A better understanding of PPR transmission dynamics in multi-host systems is necessary to efficiently control the disease, in particular where wildlife and livestock co-occur. Notably, the role of wildlife in PPR epidemiology is still not clearly understood. Non-invasive strategies to detect PPR infection without the need for animal handling could greatly facilitate research on PPR epidemiology and management of the disease in atypical hosts and in complex field situations. Here, we describe optimized methods for the direct detection of PPR virus genetic material and antigen in fecal samples. We use these methods to determine the detection window of PPR in fecal samples, and compare the sensitivity of these methods to standard invasive sampling and PPR diagnostic methods using field samples collected at a wildlife-livestock interface in Africa. Our results show that quantitative reverse transcription PCR (RT-QPCR) amplification of PPRV from fecal swabs has good sensitivity in comparison to ocular swabs. Animals infected by PPRV could be identified relatively early on and during the whole course of infection based on fecal samples using RT-QPCR. Partial gene sequences could also be retrieved in some cases, from both fecal and ocular samples, providing important information about virus origin and relatedness to other PPRV strains. Non-invasive strategies for PPRV surveillance could provide important data to fill major gaps in our knowledge of the multi-host PPR epidemiology

IF: an intermediate representation for SDL and its applications

We present work of a project for the improvement of a specification/validation toolbox integrating a commercial toolset ObjectGEODE and different validation tools such as the verification tool CADP and the test sequence generator TGV. The intrinsic complexity of most protocol specifications lead us to study combinations of techniques such as static analysis and abstraction together with classical model-checking techniques. Experimentation and validation of our results in this context motivated the development of an intermediate representation for SDL called IF. In IF, a system is represented as a set of timed automata communicating asynchronously through a set of buffers or by rendez-vous through a set of synchronization gates. The advantage of the use of such a program level intermediate representation is that it is easier to interface with various existing tools, such as static analysis, abstraction and compositional state space generation. Moreover, it allows to define for SDL different, but mathematically sound, notions of tim
