When the new Apple Watch heart monitoring app can get a reading, it can accurately detect that a person has an irregular heart rhythm known as atrial fibrillation 99 percent of the time, according to a study of the new device that Apple submitted to the Food and Drug Administration. ...In one study, Apple tested the watch in more than 580 people, half of whom had atrial fibrillation. The app couldn’t read about 10 percent of the heart rhythm recordings in the study. When it looked at the rest, though, the app was very accurate: It caught more than 98 percent of people with atrial fibrillation, and correctly told people that they didn’t have the condition 99.6 percent of the time.

She would know. Martela, a transgender woman, has been hospitalized five times for “suicidality,” a term that encompasses suicidal ideation, planning, gestures, attempts and completed suicide.

For years, eggs were synonymous with a healthy breakfast. Then the tables turned. Doctors and nutritionists started saying not to eat eggs, particularly if you wanted to avoid heart disease. The problem: Eggs contain unwanted cholesterol, and diners ingest more saturated fat when they consume eggs prepared in typical ways. But eggs also are rich in protein and other important nutrients, leading some scientists to argue that the benefits of eating eggs outweigh the risks. (9/13)
