Models have begun to play an important role in environmental assessment and urban climate studies. Their increasing use, however, is paralleled by a growing awareness that the majority of these models have never been the subject of rigorous evaluation. Consequently there is a lack of confidence in the modelled results. The paper reports on a European initiative (COST 732) which was launched 2005 with the purpose of establishing a generally accepted procedure for the improvement and quality assurance of micro-scale meteorological models that are applied for predicting flow and transport processes in urban or industrial environments.

High blood pressure is a clearly established modifiable risk factor for cardiovascular and renal disease. Although most of its adverse effects develop in adulthood, it has become clear that high BP is a lifelong problem that can manifest early in life. While few would dispute the importance of taking effective steps to identify and manage this condition in middle-aged and elderly individuals, relatively little attention has been paid to the problem of high BP in children and adolescents. Therefore, the development of actions focused on early childhood, childhood and adolescence and the investigation of the underlying causes of this epidemic are of utmost importance. There is a pressing need for comprehensive pan-European action to increase the knowledge on the prevention, diagnosis and treatment of high blood pressure in children and adolescents, the current scarcity of which impedes the development of consensus across different research fields and hinders efforts to introduce changes in clinical practice. There are some aspects that demand urgent action: the definition of hypertension, the prevalence of high BP in Europe, accurate measurement for early identification, the assessment of hypertension-mediated organ damage and the development and implementation of prevention strategies. In order to provide answers to all of these unanswered questions and challenges, a multidisciplinary network was established, maintained and funded by the European Cooperation in Science and Technology (COST) Association. COST is a funding organization for the creation of research networks known as COST Actions. In this case, the network will promote coordinated and collaborative activities on personalized preventive measures for children and adolescents across Europe., (Copyright © 2021.

Foodborne parasites (FBP) are recognized as being a neglected pathogen group, often associated with marginalized or disadvantaged populations, especially those living in regions where water supply or sanitation are inadequate. Nevertheless, we are also increasingly recognising that FBP are not just restricted to such places, and even those that do have a circumscribed endemic area may also travel further in our globalised world; FBP are relevant everywhere, including Europe. Against this background, COST Action Euro-FBP (FA1408) was established and ran for a period of 4 years, addressing a number of different questions related to FBP, particularly in the European setting. In this special issue (SI), some of the issues and outputs associated with Euro-FBP are considered in greater depth, as an output also of the final Euro-FBP meeting. As well as more general issues regarding, for example, globalization and climate change, use of economic models, and the value of risk-based surveillance that puts the topic in perspective, individual articles are included that address specific parasites. These include protozoan parasites, such as Cryptosporidium, Giardia , and Toxoplasma , as contaminants of water, shellfish, and fresh produce, fishborne parasites such as Anisakid nematodes, and meatborne parasites, such as Trichinella. Some of the works provide specific data on occurrence or outbreaks, whilst others are concerned with techniques. In addition, implementation of some of the educational and collaborative tools that are unique to COST Actions are described. COST Actions are not generally intended to deliver a scientific endpoint, and Euro-FBP does not do so. However, the articles in this SI, along with other articles published elsewhere during and subsequent to the course of the Action, as direct outputs of the Euro-FBP activities, indicate that FBP are indeed a relevant topic for European scientists. Image 1 • A COST Action on foodborne parasites (Euro-FBP) was completed in 2019. • A Special Issue arising from the final meeting was generated. • These outputs indicate that foodborne parasites (FBP) are of relevance to Europe. • Risk-based measures for control and surveillance of FBP are presented. • Knowledge transfer and exchange on FBP within Europe is shown to be important.
