Are French pig farmers and veterinarians knowledgeable about emerging foodborne pathogens? The case of hepatitis E virus.

Hepatitis E virus (HEV) is an emerging zoonotic pathogen mainly transmitted via food in developed countries, and for which domestic pigs are recognised as the main reservoir. To implement an efficient HEV surveillance and control plan in the pig production sector, it is first necessary to assess the level of knowledge of pig-farming main actors about this pathogen. To this aim, an online survey was conducted between September and October 2017 to evaluate pig farmers' and veterinarians' knowledge about HEV epidemiology and its zoonotic potential. The questionnaire was filled in by 383 pig farmers and 46 pig veterinarians. Of this population, 77.8% of farmers and 8.7% of veterinarians had never heard of HEV. Our results highlight knowledge gaps among responding farmers, especially regarding the clinical and epidemiological features of HEV, while veterinarians appear to be well-informed about this pathogen. These findings indicate significant room for further improvement and the need for more information aimed at French pig farmers, with veterinarians acting as a priority channel through which information may be transferred from scientists to farmers. These educational efforts will facilitate farmers' involvement in future HEV surveillance and control plans.

Association between quality of life of adolescents with type 1 diabetes and parents' illness perception as evaluated by adolescents.

Children and adolescents account for half of all cases of type 1 diabetes, which is one of the most common pediatric chronic diseases. The disease's effects and the treatment/disease-management protocols patients must follow can lead to a marked deterioration in quality of life, especially for adolescents. Patients' illness perceptions have been shown to impact their quality of life, but do other people's illness perceptions also have an effect? The present study addressed this question by investigating possible links between the quality of life of adolescent patients with type 1 diabetes and illness perceptions, measured in terms of the adolescents' self-perceptions, parents' self-perceptions, and the adolescents' evaluations of their parents' perceptions. We asked 41 adolescents (M = 13.9 years; SD = 1.9) who had been undergoing treatment for type 1 diabetes for at least a year (M = 6.6 years; SD = 3.7) to complete the Diabetes Quality of Life for Youth Questionnaire-Short Form (DQOLY-SF) and the Illness Perception Questionnaire-Revised (IPQ-R). They completed the IPQ-R twice, once to state their own opinions (self-report) and once to give their evaluations of their parents' perceptions. At the same time, but in a different room, their parents (N = 47) completed the IPQ-R (self-report). Quality of life was predicted by gender (p < .05) and by the parents' emotional representations (p < .01) and perceptions of consequences (p < .01) as evaluated by the adolescents. This new approach provides new insights into the impact of parents' perceptions on the quality of life of adolescents with type 1 diabetes.

[Commitment in plasmapheresis donation: A study of determinants among regular donors in plasmapheresis]. / L'engagement dans le don de plasma : étude des déterminants chez des donneurs réguliers en plasmaphérèse.

The purpose of this study, based on the Theory of planned behavior, is to identify and ultimately better understand what determines the fidelity and the regularity of donors committed in plasmapheresis donation. This qualitative study is a primary stage to establish a classification of donors in a French socio-cultural context. For this reason, we have carried out a survey among 16 regular plasmapheresis donors, by way of semi-structured individual interviews at the Établissement français du sang - Brittany. The level of commitment of these regular donors is considered as a level of appropriation. If subjective norms have initially influenced their decision to donate blood, no specific motivation has been highlighted for them to donate plasma except a generally favourable attitude towards the voluntary donation process. The perception of control over their environment is a variable which played a decisive role in the donor's intention to give, with little cost associated to plasmapheresis donation and recourse to internal causal explanations. A better comprehension of the plasmapheresis donors' determinants should lead us to a more efficient awareness of new potential donors, thereby enhancing recruitment and retention. Due to the increasing need for plasma-derived products, this study's ultimate issue is closely correlated both with ethical and socio-economic aspects. Following which, after analysing the results, a certain number of recommendations will be made.

From technological acceptability to appropriation by users: methodological steps for device assessment in road safety.

This article presents the methodology developed within the framework of the research project SARI (Automated Road Surveillance for Driver and Administrator Information). This methodology is based on the logic of action research. The article presents the different stages in the development of technological innovation addressing vehicle control loss when driving on a curve. The results observed in speed reduction illustrate that no matter how optimal an innovation may be technologically speaking, it is only as effective as it is acceptable from a user standpoint. This acceptability can only be obtained if the technology is developed by engineers in liaison with social science specialists.
