Researchers found that people born with heart defects in Denmark had a 60% higher risk of dementia compared to the general population, with those diagnosed before age 65 facing an even greater risk. The study's findings suggest that continued monitoring and management may be necessary for individuals born with congenital heart defects.
A Portland State University study found that counties with more religious populations tend to have less risk-averse hedge fund managers, resulting in smaller and younger funds. Despite this, these funds produce returns comparable to the industry average, suggesting a link between local religiosity and organizational risk-taking.
A new report highlights the persistence of smoking among vulnerable subpopulations in the US, including lower education and socioeconomic groups, certain racial/ethnic communities, and those with mental illness.
