Scientists have identified a potential driver of aggressive lung cancer tumors in patients who live in areas with high levels of violent crime. Their study found that stress responses differ between those living in neighborhoods with higher and lower levels of violent crime, and between cancerous and healthy tissues in the same individuals.
The findings are detailed in the journal Cancer Research Communications.
When scientists transplanted the gut microbes of aged mice into young “germ-free” mice — raised to have no gut microbes of their own — the recipient mice experienced an increase in inflammation that parallels inflammatory processes associated with aging in humans. Young germ-free mice transplanted with microbes from other young mice had no such increase.
The findings suggest that changes to the gut microbiome play a role in the systemwide inflammation that often occurs with aging, the researchers said.
New research from the University of Illinois Urbana-Champaign has linked multiple types of per- and polyfluoroalkyl substances (PFAS, also known as “forever chemicals”) with increased risk of cardiovascular diseases in postmenopausal women.
Residential segregation is an example of the long history of structural racism in the United States. Black Americans are more likely to live in low-quality neighborhoods, which contributes to disparities in health outcomes.
COVID-19 vaccination rates remain low in many African countries, often because providing access to vaccines is difficult in remote areas.
For people whose kidneys don’t function properly, hemodialysis is a lifesaving process. Patients visit dialysis centers multiple times per week, getting hooked up to machines that filter impurities and excess fluid out of their blood. Between sessions, dietary choices — especially sodium intake — determine the amount of fluid patients accumulate, affecting weight gain and overall quality of life. And the more fluid that needs to be taken off, the more difficult the dialysis session.

An unassuming brown bovine from the south of Brazil has made history as the first transgenic cow capable of producing human insulin in her milk.
The gut microbiome interacts with the loss of female sex hormones to exacerbate metabolic disease, including weight gain, fat in the liver and the expression of genes linked with inflammation, researchers found in a new rodent study.
The findings, published in the journal Gut Microbes, may shed light on why women are at significantly greater risk of metabolic diseases such as obesity and Type 2 diabetes after menopause, when ovarian production of female sex hormones diminishes.
