A sweeping study spanning a decade shows that playing actively with your toddler, limiting screen time and ensuring adequate sleep from age two leave a lasting imprint on how children move through life.

A national survey study led by UCLA Health and Cedars-Sinai Medical Center found significant disparities in how irritable bowel syndrome, or IBS, is diagnosed across sex and racial groups in the U.S., with men and Black patients considerably less likely than women and white patients to receive a formal diagnosis.

The global wildlife trade is doing more than threatening endangered species — it is quietly accelerating the spread of infectious diseases from animals to humans, according to a new Yale University study published in Science.

The research shows that the longer animals circulate through wildlife markets and trade networks, the more opportunities viruses, bacteria, and other pathogens have to jump into people, increasing the risk of future outbreaks of disease. 

For every 10 years an animal spends in the wildlife trade, it shares an average of one new pathogen with humans, the study found. The risk is even higher in the illegal wildlife trade and live animal markets, where animals from different regions and species are packed together under stressful, often unsanitary conditions. 

“Microbes move fast, but this is just staggering,” said Colin Carlson, assistant professor of epidemiology at the Yale School of Public Health and a co-author of the paper. “Wildlife trade has been affecting our health much faster, and for much longer, than we thought.” 

Outpatient early methadone dose titration – as recommended in Canadian and US clinical guidance for individuals using fentanyl – is associated with improved treatment retention and lower risk of opioid toxicity, according to new retrospective cohort study
