Briefs: Still more benefits for regular exercisers

More benefits for regular exercisers

Breaking a sweat at least three times a week may reduce your risk for age-related macular degeneration by up to 70 percent, Fitness magazine reports. That level of exercise helps prevent irregularities in blood vessel walls that contribute to vision woes. Further, regular exercisers cut their risk of periodontal disease by more than half — apparently because exercise helps the body regulate sugars that feed bacteria in gum tissue. And, according to the Washington Post, 40 minutes of cardiovascular exercise four times weekly can double the amount of blood flow to the hippocampus, which can enhance memory.

Care instructions unclear to patients

About 78 percent of patients in a recent survey did not fully understand the care and discharge instructions they received in the emergency department, and the vast majority of them were unaware that they did not understand what doctors had told them. The study, in the Annals of Emergency Medicine, assessed 138 patients in four categories of comprehension: diagnosis and cause, emergency department care, post-emergency department care and return instructions. More than half (51 percent) did not understand fully what they were told in two or more of the categories. Said study author Dr. Kirsten Engel of Northwestern University, outside Chicago: "Patients who fail to follow discharge instructions may have a greater likelihood of complications."

Nickel in jewelry can trigger allergy

You've broken out in a rash and don't know why. It may be the nickel in your jewelry, according to Lisa Garner, a dermatologist at Baylor Medical Center in Garland, Texas. Nickel is the most common source of metal allergies — producing problems for millions of Americans — and it is present, to a degree, in any silvery-looking metal, Garner says.

Eating slowly may assist weight loss

People looking for ways to manage their weight are often advised to eat slowly, allowing a feeling of fullness to register before they eat too much. A report in the Journal of the American Dietetic Association supports that weight-control method. Thirty healthy women were studied to compare slow and quick eating rates. The women rated their hunger, feeling of fullness (termed satiety) and other factors. A slower rate of eating led to significant decreases in food consumption, even though the meal duration was approximately 21 minutes longer. For the faster eaters, even though more food was consumed in a shorter period, their level of satiety was significantly lower than it was for the slower eaters.
