Study links adoption of electric vehicles with less air pollution and improved health
ScienceDaily | Public Health

3d ago
A team of researchers have now begun to document the actual impact of electric vehicle adoption in the first study to use real-world data to link electric cars, air pollution and health. Leveraging publicly available datasets, the researchers analyzed a 'natural experiment' occurring in California as residents in the state rapidly transitioned to electric cars, or light-duty zero emissions vehicles (ZEVs). The team compared data on total ZEV registration, air pollution levels and asthma-related emergency room visits across the state between 2013 to 2019. As ZEV adoption increased within a give ..read more

A genomic study of a sustained, multidrug-resistant Shigellosis outbreak in Seattle from 2017 to 2022 enabled scientists to retrace its origin and spread. Additional analysis of the gut pathogen and its transmission patterns helped direct approaches to testing, treatment, and public health responses. The aim of the study was to better understand the community transmission and spread of antimicrobial resistance and to treat these multi-drug resistant infections more effectively ..read more

Scientists re-writes an equation in FDA guidance to improve the accuracy of the drug interaction prediction
ScienceDaily | Public Health

A team of mathematicians and pharmaceutical scientists collaborated to identify the major cause of the low accuracy of the equation in the FDA guidance used to predict drug-drug interaction through an enzyme (cytochrome P450, CYP) induction mediation. To overcome the fundamental limit of the conventional equation, the scientists derived a new equation based on a mathematical theory. This dramatically improved the accuracy of the prediction to determine potential drug-drug interactions, which is critical in preventing drug failure and bringing about new drug development ..read more

Support from others in stressful times can ease impact of genetic depression risk, study suggests
ScienceDaily | Public Health

Reaching out to support a person when they're under stress is always a good idea. But a new study suggests that support could be especially important for someone whose genetic makeup makes them more likely to develop depression. The study shows the importance of social support in buffering the risk of developing depression symptoms in general, using data from two very different groups of people under stress: new doctors in the most intense year of training, and older adults whose spouses recently died ..read more

Reformulating packaged foods available in Australia to contain less sodium may save about 1,700 lives per year, according to a new study. Using the World Health Organization's (WHO) recommendations for reducing the population's sodium intake, the researchers estimate following the WHO sodium guidance may also prevent nearly 7,000 annual diagnoses of heart disease, kidney disease and stomach cancer in Australia ..read more

Climate risk insurance can effectively mitigate economic losses
ScienceDaily | Public Health
by

Global warming is expected to lead to an accumulation of particularly intense hurricanes in the United States. This may substantially increase the economic losses caused by these storms. Better insurance could effectively mitigate the climate change-induced increase in economic losses. This is shown in a new study examining the effectiveness of climate risk insurance in the US ..read more

Structural racism has not only psychosocial but also biological consequences. Discrimination has been shown to contribute to mental and physical disorders including obesity, depression, and addiction, but the biological pathways from a social experience to its impacts on the body remain unknown. A new study examines the role of the brain-gut microbiome (BGM) system in discrimination-related health issues ..read more
