Academic Global Health

Health globally faces a variety of challenges and barriers that need to be tackled. Global Health is a new discipline which considers (i) health of people in all nations worldwide as a consequence of globalisation (horizontal issues) and (ii) the complex influences of social determinants of health as comparable for all people (vertical issues). Academic global health approach recognises that interdependencies are increasingly relevant, while territorial boundaries become increasingly irrelevant, and that to understand both health challenges and needed solutions, the complexity of globalisation influences that transcend, or are oblivious to, territorial boundaries are beyond the capacity of individual nation states’ domestic institutions to address[...]Health globally faces a variety of challenges and barriers that need to be tackled.

Social inequality impacts upon mental health, with the less educated more likely to have psychological problems but less likely to seek treatment

Mental health is a key policy issue across Europe. Lucia Fiestas Navarrete, Mahlet Atakilt Woldetsadik and Antoine Flahault take a comprehensive look at the roles education and gender play in mental health problems in 15 European countries. They note that individuals with lower levels of education are more likely to experience psychological problems, but are also less likely to seek treatment by consulting a psychologist or taking medication. The fact that education may function as a proxy for socio-economic status suggests that socially determined inequalities have an impact on mental health outcomes

Diverse and complex challenges to migrant and refugee rental health: reflections of the M8 alliance expert group on migrant health

Forced migration is likely to continue to grow in the coming years due to climate change, disease outbreaks, conflict, and other factors. There are a huge number of challenges to maintaining good health, and specifically good mental health, among migrants at all stages of migration. It is vital to fully understand these diverse challenges so that we can work towards overcoming them. In 2017, as a response to the growing health challenges faced by migrants and refugees, the M8 Alliance created an expert group focussing on migrant and refugee health. The group meets annually at the Sapienza University of Rome, Italy, and this article is based on the discussions that took place at the third annual meeting (6-7 June 2019) and a special session on "Protecting the Mental Health of Refugees and Migrants," which took place on 27 October at the World Health Summit 2019 in Berlin. Our discussions are also supported by supplementary literature to present the diverse and complex challenges to the mental health of migrants and refugees. We conclude with some lessons learned and hope for the future

Indoor air quality and COVID-19: a scoping review

Objectives: The COVID-19 pandemic has been a major public health concern for the past 3 years. Scientific evidence on the relationship between SARS-CoV-2 infection and indoor air quality still needs to be demonstrated. This scoping review aims to study the association between air quality indoors and COVID-19. Methods: A scoping review analyzing the association between indoor air quality and epidemiological outcomes was conducted. Papers published between 1 January 2020 and 31 October 2022 were included. Hospital settings were excluded from the study. Results: Eight relevant articles met the inclusion criteria. Indoor settings included workplaces, schools, restaurants, and public transport. Types of ventilation used to improve indoor air quality were dilution methods (opening windows) and mechanical systems with or without filtration or purifier. CO2 sensors were employed in one study. All the studies showed a positive association between indoor air quality and its improvement and epidemiological indicators. Conclusion: The findings of this scoping review indicate that indoor air quality, which can be improved with ventilation methods, may reduce the risk of developing COVID-19. Ventilation could thus be viewed as a possible effective mitigating method

The unexpected importance of mosquito oviposition behaviour for malaria: non-productive larval habitats can be sources for malaria transmission

BACKGROUND: Mosquitoes commute between blood-meal hosts and water. Thus, heterogeneity in human biting reflects underlying spatial heterogeneity in the distribution and suitability of larval habitat as well as inherent differences in the attractiveness, suitability and distribution of blood-meal hosts. One of the possible strategies of malaria control is to identify local vector species and then attack water bodies that contain their larvae. METHODS: Biting and host seeking, not oviposition, have been the focus of most previous studies of mosquitoes and malaria transmission. This study presents a mathematical model that incorporates mosquito oviposition behaviour. RESULTS: The model demonstrates that oviposition is one potential factor explaining heterogeneous biting and vector distribution in a landscape with a heterogeneous distribution of larval habitat. Adult female mosquitoes tend to aggregate around places where they oviposit, thereby increasing the risk of malaria, regardless of the suitability of the habitat for larval development. Thus, a water body may be unsuitable for adult mosquito emergence, but simultaneously, be a source for human malaria. CONCLUSION: Larval density may be a misleading indicator of a habitat's importance for malaria control. Even if mosquitoes could be lured to oviposit in sprayed larval habitats, this would not necessarily mitigate – and might aggravate – the risk of malaria transmission. Forcing mosquitoes to fly away from humans in search of larval habitat may be a more efficient way to reduce the risk of malaria than killing larvae. Thus, draining, fouling, or filling standing water where mosquitoes oviposit can be more effective than applying larvicide

What we need to improve the Public Health Workforce in Europe?

With the growth and complexity of current challenges such as globalization, health threats, and ageing society, financial constraints, and social and health inequalities, amultidisciplinary public health workforce is needed, supported by new skills and expertise. It has been demonstrated that public health education needs to include a wider range of health related professionals including: managers, health promotion specialists, health economists, lawyers and pharmacists. In the future, public health professionals will increasingly require enhanced communication and leadership skills, as well as a broad, interdisciplinary focus, if they are to truly impact upon the health of the population and compete successfully in today‘s job market. New developments comprise flexible academic programmes, lifelong learning, employability, and accreditation. In Europe‘s current climate of extreme funding constraints, the need for upgrading public health training and education is more important than ever. The broad supportive environment and context for change are in place. By focusing on assessment and evaluation of the current context, coordination and joint efforts to promote competency-based education, and support and growth of new developments, a stronger, more versatile and much needed workforce will be developed

Influenza Epidemics in the United States, France, and Australia, 1972–19971

Influenza epidemics occur once a year during the winter in temperate areas. Little is known about the similarities between epidemics at different locations. We have analyzed pneumonia and influenza deaths from 1972 to 1997 in the United States, France, and Australia to examine the correlation over space and time between the three countries. We found a high correlation in both areas between France and the United States (correlation in impact, Spearman’s ρ = 0.76, p < 0.001, and test for synchrony in timing of epidemics, p < 0.001). We did not find a similar correlation between the United States and Australia or between France and Australia, when considering a systematic half-year lead or delay of influenza epidemics in Australia as compared with those in the United States or France. These results support a high correlation at the hemisphere level and suggest that the global interhemispheric circulation of epidemics follows an irregular pathway with recurrent changes in the leading hemisphere

Trend estimation and short-term forecasting of COVID-19 cases and deaths worldwide

Since the beginning of the COVID-19 pandemic, many dashboards have emerged as useful tools to monitor the evolution of the pandemic, inform the public, and assist governments in decision making. Our goal is to develop a globally applicable method, integrated in a twice daily updated dashboard that provides an estimate of the trend in the evolution of the number of cases and deaths from reported data of more than 200 countries and territories, as well as a seven-day forecast. One of the significant difficulties to manage a quickly propagating epidemic is that the details of the dynamic needed to forecast its evolution are obscured by the delays in the identification of cases and deaths and by irregular reporting. Our forecasting methodology substantially relies on estimating the underlying trend in the observed time series using robust seasonal trend decomposition techniques. This allows us to obtain forecasts with simple, yet effective extrapolation methods in linear or log scale. We present the results of an assessment of our forecasting methodology and discuss its application to the production of global and regional risk maps.Comment: 15 pages including 5 pages of supplementary materia
