Home score for strep throat in adults could avoid unnecessary doctor visits

Telling the difference between run-of-the-mill sore throat caused by a virus, which doesn’t require medication, from bacteria-caused strep throat, which should be treated with antibiotics, is a tricky thing at any age. Physicians from Harvard Medical School, MIT, and the Skaggs School of Pharmacy in California have come up with a scoring system that could save adults a trip to the doctor for what would most likely turn out to be a garden variety sore throat (it hasn’t been tested in kids yet). It’s based on symptoms, age, and the percentage of people in your area who have tested positive for strep within the last two weeks. If your score is high, then head to your doctor’s office. If it indicates that you are unlikely to have strep, there’s little need for you to rush in for an exam or throat culture. The researchers estimate that use of this kind of score could prevent 230,000 office visits in the United States each year and keep 8,500 men and women from getting antibiotics they don’t need.

Daylight Saving Time “fall back” doesn’t equal sleep gain

Daylight Saving Time officially ends at 2:00 am this Sunday. In theory, “falling back” means an extra hour of sleep this weekend. But it doesn’t usually work out that way. Many people don’t, or can’t, take advantage of this weekend’s extra hour of sleep. And the focus on gaining or losing an hour of sleep overlooks the bigger picture—the effect of Daylight Saving Time transitions on the sleep cycle. This seemingly small one-hour shift in the sleep cycle can affect sleep for up to a week. It’s difficult to side-step the effects of Daylight Saving time on sleep. So be aware that it can take your sleep rhythms a week or so to get adjusted to the new clock.
