PFAS exposure, high-fat diet drive prostate cells’ metabolism into pro-cancer state: Dietary fat synergizes with PFAS to trigger cancer in benign cells, accelerate tumor growth in malignant cells
Exposure to PFAS — a class of synthetic chemicals utilized in food wrappers, nonstick cookware and other products — reprograms the metabolism of benign and malignant human prostate cells to a more energy efficient state that enables the cells to proliferate at three times the rate of nonexposed cells, a new study in mice found.

Masks Limited COVID Transmission in Unvaxxed College Kids
Masking worked, along with fewer exposure encounters, to help limit the incidence of COVID-19 infection among largely unvaccinated university students in Missouri, researchers found. Among nearly 400 close contacts of students who tested positive for SARS-CoV-2, the likelihood of a positive test result was more than five times higher in situations where at least one […]
How Long Is a Person Contagious With Mono?
After exposure to the virus, someone with mono can be contagious for months, even before symptoms start and after symptoms subside Infectious mononucleosis, also called mono, is a contagious disease most commonly caused by the Epstein-Barr virus (EBV). It’s unclear how long someone with mono is contagious, although they are definitely contagious while they have […]
Fasting may help ward off infections, study in mice suggests
Fasting before and during exposure to Salmonella enterica bacteria protects mice from developing a full-blown infection, in part due to changes in the animals’ gut microbiomes,according to new research published in PLOS Pathogens by Bruce Vallance and colleagues at University of British Columbia, Canada. When people or animals develop an infection, they often lose their […]
Some IBD Treatments in Pregnancy Had No Effect on Kids’ Infection Risk
Exposure to immunosuppressive monotherapies in utero did not increase serious infection risks in young children born to mothers with inflammatory bowel disease (IBD), but the same could not be said for exposures to combination therapies, a French population-based study found. Children up to 1 year of age who were exposed to tumor necrosis factor (TNF) […]
Study: Exposure Therapy for Irritable Bowel Syndrome Saves Money
Including exposure therapy during internet-based cognitive behavioral therapy (ICBT) was associated with reduced treatment costs in irritable bowel syndrome (IBS), a Swedish randomized trial found. While use of ICBT with exposure initially increased direct patient costs by 20% ($213.50 per participant) versus ICBT without exposure, the added therapy led to greater reductions in societal costs […]
