1. Hospital admission rates vary widely across England's emergency departments

   Neither local case mix, primary care provision, nor geography explain the large differences in hospital admission rates, ranging from less than 10% to more than 40%, from emergency departments across England, finds research published online in Emergency Medicine Journal.

2. Study reveals potential link between limited cold stress during pregnancy and birth weight

   Research out of South Dakota State University has highlighted a potential connection between limited exposure to cold stress during pregnancy and birth weight.

3. Autism diagnosis patterns change as psychiatric profiles shift across Europe

   The medical profiles of adults diagnosed with autism have changed hugely since 2010, finds a study of medical records in the UK and Sweden, published in the online journal BMJ Mental Health.

4. AlphaFold3 reveals molecular interactions driving T cell recognition

   Researchers at the Translational Genomics Research Institute (TGen), part of City of Hope, have developed a new approach using the artificial intelligence platform AlphaFold3 to predict whether a T cell receptor will recognize a specific antigen based solely on its genetic sequence.

5. Historically redlined neighborhoods report higher opioid overdose death rates

   A new study from researchers at Boston Medical Center (BMC), the largest essential hospital in New England, found that Massachusetts neighborhoods given the lowest grades on historic redlining maps had 86% higher annual opioid-related overdose death rates than those given the highest grades.

6. TAVR procedures increase ninefold among patients younger than 70
