Smartphone videos of the sit-to-stand test predict osteoarthritis and health outcomes in a nationwide study

Musculoskeletal conditions—which encompass impairments of the joints, bones, or muscles—affect more than 1.5 billion people around the world. Like most health problems, catching these issues early could potentially prevent serious disorders, but few quantitative and objective tests to assess musculoskeletal health are available.

Childhood trauma linked to reduced vascular function and diminished sleep quality

Adverse childhood experiences (ACEs) contribute to reduced vascular function and diminished sleep quality in young adults, according to a study at the University of Iowa. In addition, researchers found that poor sleep efficiency may contribute to vascular dysfunction with increasing ACEs exposure. Researchers will present their work this week at the American Physiology Summit, the flagship annual meeting of the American Physiological Society (APS), in Long Beach, California.
