Double whammy for grieving spouses with sleep problems

A new study from Northwestern University finds that grieving spouses with sleep problems have a two-to-three times higher risk of chronic immune activation and increased inflammation, making them more susceptible to heart disease or cancer. Cognitive behavioral therapy is highly effective in treating sleep disturbances, and physicians ...

Facial exercise speeds Botox's wrinkle-reducing effects

A new study by Northwestern University found that facial exercise after Botox injections can make wrinkle reduction occur one day sooner. The exercises included raised motions of the forehead and scowls, which improved forehead wrinkles by two to three days after treatment when followed by facial exercise.

Drug improves survival in metastatic breast cancer

A phase III clinical trial found that palbociclib improves overall survival in women with hormone receptor-positive metastatic breast cancer. The drug, used in combination with standard treatment, led to a clinically meaningful improvement in median overall survival, even in patients who showed sensitivity to prior hormone therapy.
