A study initiated by the European Spondyloarthritis Research Collaboration Network (EuroSpA) examined whether patients' countries of residence are associated with the severity of their psoriatic arthritis (PsA) or axial spondyloarthritis (axSpA), when they begin advanced treatment and how long they continue that treatment. Findings in the Annals of the Rheumatic Diseases, found evidence that patients from wealthier European countries tend to start treatment with biologics earlier but also stop or switch treatment earlier. They also experience lower disease activity at treatment start than patients in middle- and low-income countries.

Heart disease is the leading cause of death in the United States, according to the Journal of the American College of Cardiology. Its impact extends beyond biology, with social determinants such as food insecurity, socioeconomic status and education influencing outcomes.

Researchers at Columbia University Mailman School of Public Health, in collaboration with investigators at the University of Chicago, have developed a new computational framework that helps scientists identify genes that play central roles in diseases such as asthma but are often overlooked by existing genetic analysis methods.

A new study of sunscreens, baby lotions, shampoos, soaps and other everyday products found that nearly all contained chemicals not disclosed on their labels. Most contained at least one unlabeled chemical with known or suspected health hazards, and one in four contained a chemical that contradicted claims on the package, including "phthalate-free" products that contained phthalates. The research is published in Environment & Health.

A single blood test could in the future provide a more comprehensive picture of cancer than current methods. In a review article published in the journal Genome Medicine, researchers at Karolinska Institutet describe how several different biological signals can be analyzed simultaneously from the same blood sample to detect and monitor cancer diseases.
