Having a health insurance plan with a high deductible could not only cost you—it could also kill you. A new study in JAMA Network Open found that people who faced those high out-of-pocket costs as well as a cancer diagnosis had worse overall survival and cancer-specific survival than those with more standard health plans.

These might include recurring mentions of cognitive changes or confusion from the patient, or worries mentioned by family members attending the appointment with their loved one.Rather than diagnosing cognitive decline or dementia directly, the…

The best example of Nvidia’s passion for support is, believe it or not, a two-year gap in updates.

Most notably, there were no public updates for the Shield TV in 2023 or 2024, but over-the-air updates resumed in 2025. “On the outside, it looked like we went quiet, but it’s actually one of our bigger development efforts,” explained Bell.
