Pressure flowfield and inlet flow distortion metrics reconstruction from velocity data

Complex engine intakes are susceptible to unsteady flow distortions that may compromise the propulsion system operability. Hence, the need for high spatial and temporal resolution flow information is essential to aid the development of distortion tolerant, closely coupled propulsion systems. Stereoscopic PIV methods have been successfully applied to these flows offering synchronous velocity datasets of high spatial resolution across the Aerodynamic Interface Plane. However, total pressure distortion measurements are still typically provided by low bandwidth, intrusive total pressure rakes of low spatial resolution which results in limited characterisation of the total pressure distortion. This limitation can potentially be addressed by pressure field reconstruction from non-intrusive, high resolution velocity data. A range of reconstruction methods are assessed based on representative data from steady and unsteady computational simulations of an S-duct configuration. In addition to the reconstructed total pressure field, the impact on the key distortion metrics is assessed. The effect of Mach number is considered. Overall the reconstruction methods show that the distortion metrics can be determined with sufficient accuracy to indicate that there is a potential benefit from exploiting high resolution velocity measurements in evaluating total pressure distortion

The Use of Digital Technologies to Support Vaccination Programmes in Europe: State of the Art and Best Practices from Experts’ Interviews

Digitalisation offers great potential to improve vaccine uptake, supporting the need for effective life-course immunisation services. We conducted semi-structured in-depth interviews with public health experts from 10 Western European countries (Germany, Greece, Italy, Luxembourg, Malta, the Netherlands, Norway, Poland, Portugal, and the United Kingdom) to assess the current level of digitalisation in immunisation programmes and retrieve data on interventions and best practices. Interviews were performed using an ad hoc questionnaire, piloted on a sample of national experts. We report a mixed level of digital technologies deployment within vaccination services across Europe: Some countries are currently developing eHealth strategies, while others have already put in place robust programmes. Institutional websites, educational videos, and electronic immunisation records are the most frequently adopted digital tools. Webinars and dashboards represent valuable resources to train and support healthcare professionals in immunisation services organisation. Text messages, email-based communication, and smartphone apps use is scattered across Europe. The main reported barrier to the implementation of digital-based programmes is the lack of resources and shared standards. Our study offers a comprehensive picture of the European context and shows the need for robust collaboration between states and international institutions to share best practices and inform the planning of digital intervention models with the aim of countering vaccine hesitancy and increasing vaccine uptake

The spread of COVID-19 in six western metropolitan regions:a false myth on the excess of mortality in Lombardy and the defense of the city of Milan

We analyzed the spread of the COVID-19 epidemic in 6 metropolitan regions with similar demographic characteristics, daytime commuting population and business activities: the New York metropolitan area, the Île-de-France region, the Greater London county, Bruxelles-Capital, the Community of Madrid and the Lombardy region. The highest mortality rates 30-days after the onset of the epidemic were recorded in New York (81.2 x 100,000) and Madrid (77.1 x 100,000). Lombardy mortality rate is below average (41.4 per 100,000), and it is the only situation in which the capital of the region (Milan) has not been heavily impacted by the epidemic wave. Our study analyzed the role played by containment measures and the positive contribution offered by the hospital care system. (www.actabiomedica.it)

“This Is Public Health in Italy”. An ASPPH-ASPHER campaign to raise awareness on health prevention and Health in All Policies

Introduction In many European countries, Public Health (PH) and Preventive Medicine are not perceived as important tools 1 2.The general population, especially those working in non-healthcare related fields, underestimates the crucial role of PH policies as food & veterinary safety, energy efficiency, transport regulation, healthcare design and city planning 3-8. The Health in All Policies (HiAP) approach is instrumental in tackling this information gap 9 10. Originally conceived in the EU, HiAP is now included in WHO’s Sustainable Development Goals. In the US, in 2018, the Association of Schools & Programs of Public Health (ASPPH) launched an international campaign called “This is Public Health” (TIPH), whose aim was “to brand public health and raise awareness of how [it] affects individuals, families, communities, and populations” 11. The Association of Schools of Public Health in the European Region (ASPHER) responded by creating a European campaign to reproduce the American one. An open challenge was set, in which PH Schools – students and staff – were requested to formulate country-specific proposals. The Accademia Lombarda di Sanità Pubblica, coordinating the Schools and Programs of PH of Vita-Salute “San Raffaele” University, Milan, University of Parma, University of Pavia and Politecnico of Milan set up a proposal to increase PH awareness both in the general population and in healthcare workers. Materials and methods The preliminary phase was dedicated to the Project setup and was conducted by the ten new Residents of the Vita-Salute “San Raffaele” University, with the coordination and supervision of the PI and the Schools’ Directors. The working group extensively discussed the need for an appropriate translation of the catchphrase and a new graphic rendering of the TIPH logo. An agreement was finally reached to adapt all the elements of the Campaign, re-elaborating them according to the Italian context. The word “health” has a double meaning in Italian (“salute” and “sanità”). Furthermore, people with limited English proficiency are a large part of the target population. Therefore, the Group opted for a non-literal translation (“Per la salute di tutti”). To further boost the Campaign online, the group created “TIPH – Italy” accounts and pages on the main social media (i.e. Facebook, Twitter, Instagram). Subsequently, the PI assigned tasks to each of the team’s members from the various PH Schools involved. The operational phase is currently underway, and a series of activities are already in schedule. All laws and resolutions enacted by local governments (Lombardy Region and, in a future phase, Emilia Romagna Region) are being thoroughly analysed, to assess their direct or indirect PH impact. Spreading the project will be a key for its success. In the next months, multiple promotional events will be organised, addressing both operators and the public at large. Surveys will be administered before and after the events, both to assess baseline knowledge and attitudes towards PH initiatives, and to verify the interventions’ effectiveness in raising awareness. Running a social media photo contest will be a useful option for targeting younger age groups, following in the steps of the US campaign. Side events will be organised, such as congress, meeting, press conferences, with the purpose of giving the latest updates about the Campaign. Conclusions Italy is a challenging country. A fairly strong National Health Service, with plenty of positive health indicators, coexist with impressive inequalities and contradictions, both in the North-South and in the rich-poor axis. In light of this scenario, stronger recognition of the role and the importance of PH is essential. PH awareness is ultimately directed at informing policymaking and improving community health 12. While the potential impact of TIPH in Italy is still to be fully explored, the basis for its potential success can only lie in the delivery of a culturally appropriate message. TIPH Italy is a wonderful opportunity of making PH accessible to the general population in an effective, yet entertaining way

The campaign "This Is Public Health" in Italy, set up by a team of Public Health Schools in Northern Italy

Despite the great effort to raise awareness among health promotion, nowadays Public Health policies are not often recognized as important tools. For this reason, the Health in All Policies (HiAP) approach is instrumental in tackling this information gap. In 2018, the US Association of Schools and Programs of Public Health (ASPPH) launched an international campaign called "This is Public Health" (TIPH), whose aim was "to brand public health and raise awareness of how it affects individuals, communities and populations". The Association of Schools of Public Health in the European Region (ASPHER), in coordination with ASPPH, decided to create a European campaign to support and to reproduce the American one, by opening a challenge among the European Public Health Schools. The Schools and Programs of PH of Vita-Salute "San Raffaele" University, Milan, University of Parma, University of Pavia and Politecnico of Milan won this bid. In this "briefing on" we present a report on the Italian project for raising awareness of Public Health among general population and health care personell
