Creating Audio-Visual Content for a Personalized Prevention Programme in Coronary Heart Disease

Coronary heart disease (CHD) remains the leading cause of premature death worldwide. Better risk stratification tools and personalized care of patients are needed for reducing the morbidity and mortality of CHD and the associated economic burden. However, contemporary e-learning solutions lack personalization and shared decision making and as a result, overwhelm patients with large amounts of information. CoroPrevention is a multiyear, EU-funded Horizon 2020 research project aiming to shape and implement a personalized secondary prevention strategy for patients with established CHD. As a part of the project, new digital tools will also be validated. In this paper, we discuss the process of creating audio-visual content for the CoroPrevention mobile application during the challenging COVID-19 pandemic. © 2022 IEEE.

Integrating “Impacts of Covid-19 pandemic on air quality” in STEM courses and internships for undergraduate students

Air pollution is a global public health concern and has led to millions of premature deaths worldwide. In overpopulated cities, particulate matter such PM2.5, nitrogen dioxide (NO2), and ozone (O3) in the troposphere have deleterious effects on human health leading to cardiovascular and respiratory diseases. The students in two undergraduate courses (Principles of Biology for Honors students and Ecology) and one graduate course (Teaching STEM at the K-12 schools) at the University of Maryland Eastern Shore;and summer-exchange undergraduate engineering interns learnt about the positive and negative effects of Covid-19 pandemic on air quality for some of the selected overpopulated cities in the world that witnessed lockdowns from March 2020 through spring 2021. The STEM students as well as the interns had the opportunity to learn how to analyze the real-time and historical air quality data from the Environmental Protection's Agency's centralized data system, AirNow, as well as from the Air Quality Open Data Platform (https://aqicn.org/data-platform/covid19) Worldwide Covid-19 dataset. For the above-mentioned courses, the materials pertaining to Covid-19 and air quality were taught in the form of modules (two for each course) with lectures;discussions and class debates;video materials;simulations with real-time data;and a project centering on that theme. The engineering students who worked as summer interns worked on analyzing data from five of the major cities in the world. Besides analyzing the effects of the pandemic on PM2.5, NO2, and O3 in the selected populated cities, the students also studied whether any correlations existed among the air quality parameters or not. The students' learning outcomes included honing content knowledge in atmospheric chemistry and physics of particulate matter;environmental sciences and engineering;public health and policies;research skills with respect to data analysis and problem-solving;as well as presentation and writing skills. The students and interns in the courses and internships also addressed and debated on the various issues of sustainability, which encompasses social, environmental, economic considerations along with policies. The crisis of the pandemic on climate change is dependent on the policies of the governments towards which directions the economies need to head. When the governments prioritize to shift from fossil fuels to cleaner energy such as wind, solar, geothermal, biofuels, then the mitigation efforts of climate change could come to fruition. It is anticipated that with more ongoing collaborations across disciplines, the authors will be able to permanently integrate these diverse components in other STEM courses such as Statistics for Engineers, Big Data Analytics, and enhance multidisciplinary learning for all majors. This integration of research findings in STEM courses is a reflection of the KDB (Know, Do, Be) framework, as the interns and the students honed their skills not only in content knowledge through inquiry, but felt responsible in taking action towards mitigation efforts of climate change. © American Society for Engineering Education, 2022

The casual effects of COVID-19 lockdown on air quality and short-term health impacts in China.

The outbreak of coronavirus (COVID-19) has forced China to lockdown many cities and restrict transportation, industrial, and social activities. This provides a great opportunity to look at the impacts of pandemic quarantine on air quality and premature death due to exposure to air pollution. In this study, we applied the difference-in-differences (DID) model to quantify the casual impacts of COVID-19 lockdown on air quality at 278 cities across China. A widely used exposure-response function was further utilized to estimate the short-term health impacts associated with changes in PM2.5 due to lockdown. Results show that lockdown has caused drastic reduction in air pollution level in terms of all criteria pollutants except ozone. On average, concentrations of PM2.5, PM10, NO2, SO2 and CO are estimated to drop by 14.3 µg/m3, 22.2 µg/m3, 17.7 µg/m3, 2.9 µg/m3, and 0.18 mg/m3 as the result of lockdown. Cities with more confirmed cases of COVID-19 are related to stronger responses in air quality, despite that similar lockdown measures were implemented by the local governments. The improvement of air quality caused by COVID-19 lockdown in northern cities is found to be smaller than that of southern cities. Avoided premature death associated with PM2.5 exposures over the 278 cities was estimated to be 50.8 thousand. Our results re-emphasize the effectiveness of emission controls on air quality and associated health impacts. The high cost of lockdown, still high level of air pollution during lockdown and smaller effects in northern cities implies that source-specific mitigation policies are needed for continuous and sustainable reduction of air pollution.

Combatting Covid-19. Or, "All Persons Are Equal but Some Persons Are More Equal than Others?"

Vaccines, when available, will prove to be crucial in the fight against Covid-19. All societies will face acute dilemmas in allocating scarce lifesaving resources in the form of vaccines for Covid-19. The author proposes The Value of Lives Principle as a just and workable plan for equitable and efficient access. After describing what the principle entails, the author contrasts the advantage of this approach with other current proposals such as the Fair Priority Model.
