Some people living with chronic stress have a higher risk of stroke, study finds

Some people living with chronic stress have a higher risk of stroke, according to a study published in Neurology. The study looked at younger adults and found an association between stress and stroke, with no known cause, in female participants, but not male participants. This study does not prove that stress causes stroke; it only shows an association.

Hormone therapy among older women linked to tau accumulation, a hallmark of Alzheimer’s disease

A new study by Mass General Brigham researchers has found faster accumulation of tau—a key indicator of Alzheimer’s disease—in the brains of women over the age of 70 who took menopausal hormone therapy (HT) more than a decade before. The results, which are published in Science Advances, could help inform discussions between patients and clinicians about Alzheimer’s disease risk and HT treatment.

Engineered cartilage from nasal septum cells helps treat complex knee injuries

Injuries to the articular cartilage in different joints, including the knee, are painful and limit mobility. In response, researchers at the University of Basel and University Hospital Basel are developing cartilage implants using cells from the patient’s nasal septum. A recent study shows that giving these cartilage implants more time to mature significantly improved clinical efficacy, even in patients with complex cartilage injuries. This suggests that the method could also be suitable for the treatment of degenerated cartilage in osteoarthritis.
