Susceptible-exposed-infectious-recovered (SEIR) models were applied to assess the effectiveness of non-pharmaceutical interventions (NPIs) and to study the dynamic behavior of the COVID-19 pandemic. Recently, SEIR models have evolved to address the change of human mobility by some NPIs for predicting the new confirmed cases. However, the models have serious limitations when applied to Seoul. Seoul has two representative quarantine policies, i.e. social distancing and the ban on gatherings. Effects of the two policies need to be reflected in different functional forms in the model because changes in human mobility do not fully reflect the ban on gatherings. Thus we propose a modified SEIR model to assess the effectiveness of social distancing, ban on gatherings and vaccination strategies. The application of the modified SEIR model was illustrated by comparing the model output with real data.

Climate change creates unique forms of psychological distress for Indigenous Peoples whose identities and cultural practices are often intrinsically connected to ancestral lands, yet research on culturally appropriate methodologies for studying Indigenous mental health in the context of climate change remains limited. This perspective paper presents methodological reflections from Land Body Ecologies research collective, which collaborates with Ogiek (Kenya), Batwa (Uganda), Iruliga (India), Pgak'yau (Thailand) and Sámi (Sápmi) Indigenous Peoples to explore climate change-related mental health impacts through the lens of solastalgia. Through participatory dialogues conducted during in-person gatherings, team members reflected on three years of community-based participatory research and identified two critical methodological challenges underexplored in the existing literature: (1) language and concept translation difficulties, where terms such as 'mental health' and 'climate change' lack direct cultural equivalents and may carry stigmatising connotations and (2) barriers to cultural practices, where climate change and conservation-related legislation restricts Indigenous Peoples' access to ancestral lands and traditional practices essential for well-being.

The connection between vitamin D (VitD) deficiency and aberrant electrocardiographic activity was investigated. We included all papers that looked at the association between VitD deficiency and electrocardiographic activity.

Objectives: Injuries are the leading cause of death among children and adolescents. Although numerous risk assessment tools for unintentional injuries in children have been developed and published both domestically and internationally, there is currently no global consensus on standardized use. This study aims to systematically characterize existing unintentional injury risk assessment tools for children aged 0-6 years, with the goal of informing scientific tool selection and optimization.

This article examines the history of risk assessments of the organophosphate pesticide chlorpyrifos at the US Environmental Protection Agency (EPA), especially after a ban on household uses in 2000. Federal funding enabled more noncorporate and place-based scientific investigations of this pesticide's harms, including child-cohort epidemiology of populations impacted through environmental injustices. This article argues, first, that their findings challenged the thin knowledge base, mostly from corporate-sponsored toxicology, that originally justified chlorpyrifos's continued use.

To combat this, the WHO recommends the implementation of its 'best buy' policies-three cost-effective alcohol policies that include higher taxes, restricted availability and marketing bans. While evidence links alcohol marketing to increased consumption, the effectiveness of marketing bans in decreasing alcohol use remains inconclusive.
