PSA tests detect 30 percent more cancers but may cause overtreatment

Blood tests to detect potential signs of prostate cancer likely reduce the risk of dying from prostate cancer, an updated Cochrane review finds. This is a shift from the previous version of the review, which did not find sufficient evidence that screening reduced prostate cancer deaths.

Too little or excessive sleep may accelerate organ aging

An analysis of biological clocks throughout the human body suggests that too few hours of sleep-and too many-may speed aging in the brain, heart, lung, and immune system and is associated with a wide range of diseases.

Could a fingerprick at home flag your Alzheimer's risk? New study says yes

Researchers demonstrated that self-administered fingerprick blood tests measuring p-tau217 and GFAP, returned by post, correlate strongly with venous blood biomarkers and cognitive performance across the Alzheimer's disease continuum. Combined with computerized cognitive testing, this at-home approach offers a scalable, patient-friendly tool for triaging individuals at risk of AD-related impairment.

Blood test may improve early tuberculosis detection among household contacts

Household contacts of people with tuberculosis (TB) have a high risk of getting TB themselves, at around 2 percent. It is currently difficult to detect TB in its early stages, or predict who will go on to have TB, and therefore preventive treatment is not widely used.

New map reveals B cell clusters linked to faster diabetic kidney disease

A detailed new map of the human kidney revealed a previously unrecognized form of diabetic kidney disease (DKD) marked by clusters of immune cells-specifically B cells-that are linked to faster disease progression.
