The popularity of bulldogs and other flat-faced pets is at an all-time high. According to the American Kennel Club, from 2006-2016, the number of registered bulldogs and French bulldogs in the U.S. increased by 60% and 476%, respectively. In 2023, the French bulldog topped the AKC’s most popular breeds list. University of Illinois Urbana-Champaign veterinary surgeon Dr. Heidi Phillips devotes much of her practice to treating the respiratory problems of flat-faced breeds like bulldogs. She argues for better breeding practices to avoid perpetuating the many health problems these breeds experience.

A new study links increased use of acetaminophen during pregnancy – particularly in the second trimester – to modest but noticeable increases in problems with attention and behavior in 2-, 3- and 4-year-olds. The study adds to a growing body of evidence linking the frequent use of acetaminophen in pregnancy to developmental problems in offspring.

Acetaminophen is considered the safest over-the-counter pain reliever and fever reducer available during pregnancy and studies have shown that 50%-65% of women in North America and Europe take the analgesic during pregnancy. A new study from researchers at the University of Illinois Urbana-Champaign explored the relationship between acetaminophen use during pregnancy and language outcomes in early childhood. It found that increasing acetaminophen use was associated with language delays.

Seven years after an initial $17.9 million award from the National Institutes of Health, the Illinois Kids Development Study at the University of Illinois Urbana-Champaign will receive approximately $13.7 million – awarded in two phases – to continue its work for another seven years. The money coming to Illinois is part of a national collaborative effort to explore how environmental exposures influence child development, cognition, growth and health.

When an immunocompromised person’s system begins to recover and produce more white blood cells, it’s usually a good thing – unless they develop C-IRIS, a potentially deadly inflammatory condition. New research from the University of Illinois Urbana-Champaign has found that the pulmonary distress often associated with C-IRIS is caused not by damage to the lungs, but by newly populated T-cells infiltrating the brain. Knowing this mechanism of action can help researchers and physicians better understand the illness and provide new treatment targets.

A new paper spanning known data about the neurotransmitter GABA and its principal receptors showcases evidence of the receptors’ importance in depression and potential as therapeutic targets. Based on evidence from research on the receptors’ function in the brain and the drugs that can activate or inhibit them, the authors propose possible mechanisms by which GABA-modulating treatments could help address the cognitive and affective symptoms associated with depression.

In an advance that will help scientists track coronavirus variants in wild and domesticated animals, researchers report they can now detect exposure to the SARS-CoV-2 virus in any animal species.

Sending ailing dogs home with oral opioids may not be an effective way to manage their pain, experts report in a free, online continuing education program recently developed for veterinarians. In light of growing evidence that such drugs don’t work well in dogs – added to the fact that humans sometimes abuse opioids prescribed for pets – the common practice of prescribing oral opioids for dogs in pain should be reexamined, the experts say.

Anticipating the need among opioid prescribers for additional training to meet regulatory mandates, these experts created an online continuing education program that addresses the problem. The training includes cautions about unwarranted prescription of oral opioids and advice on effective pain management for veterinary patients.
