More and more experts now recommend that people with high blood pressure regularly check their blood pressure at home. Doing this gives people an idea where their blood pressure stands in between office visits, and can motivate them to care more about their health. It also helps doctors make quick medication adjustments to keep blood pressure in the healthy zone. But according to a new study, up to 15% of home blood pressure monitors as accurate as they should be. Readings can be off by as much as 20 points. If you check your blood pressure at home, bring your monitor and cuff to your doctor’s office and compare the reading you get with the doctor’s known, accurate instrument.
Getting a flu shot can help ward off the flu. It also works to prevent pneumonia, a leading cause of hospitalization (about one million a year) and death (about 50,000) in the United States. Pneumonia can be especially dangerous in young children and older people. For these groups, as well as others who face a high risk of pneumonia, two different vaccines can help prevent pneumonia caused by the bacterium known as Streptococcus pneumoniae. One, called PPSV23 or Pneumovax, is derived from 23 different types of pneumococcal bacteria. A newer vaccine, called PCV13, features parts of 13 different pneumococcal bacteria linked to a protein that helps the vaccine work better. PCV13 is recommended for all children younger than 5 years old, all adults 65 years or older, and anyone age 6 or older with risk factors for pneumonia. PPSV23 is recommended for all adults 65 years or older and anyone age 2 years through 64 years are at high risk of pneumonia.
Smells and tastes are often sources of great pleasure. They can also spark wonderful memories. But like memories, these senses can fade, or even disappear, with age. A new study suggests that loss of smell may be a canary in the coal mine—an early warning that something else is wrong in the body. In the study, published in PLoS ONE, older people who lost their sense of smell were more likely to have died over a five-year period. Previous research has linked loss of smell to the onset of neurodegenerative diseases such as Alzheimer’s disease and Parkinson’s disease. What to do If your sense of smell has faded? Don’t jump to conclusions. Diminished smell function is usually caused by problems in the nose, not in the brain.
Combining a chemotherapy drug called docetaxel with hormone therapy (androgen-deprivation therapy) to treat advanced prostate cancer appears to work better than starting with hormone therapy and adding docetaxel later.
Prostate cancer tends to be more aggressive in men with low levels of vitamin D. Among African American men, low vitamin D is also linked to a higher risk of developing prostate cancer.
The New York Times has described Thomas Eric Duncan, the first person to die of Ebola virus infection in the United States, as “the Liberian man at the center of a widening health scare.” Use of the term “health scare” about Ebola in the U.S. just isn’t warranted, according to a consensus of several Harvard experts who have looked at Ebola through different lenses. They give four main reasons why an epidemic of Ebola virus disease isn’t likely to happen here: 1) the virus is relatively difficult to spread; 2) we have an effective emergency-response infrastructure; 3) Most hospitals are equipped to treat Ebola safely; and 4) new treatments are in the works.
A report published this week in the Journal of the American Medical Association offers weak-to-no proof that acupuncture helps ease the pain of knee arthritis. In a group of older men and women with arthritis-related knee pain, Australian researchers compared traditional needle acupuncture against laser acupuncture, sham laser acupuncture, and no treatment. People who had needle or laser acupuncture reported slightly less pain and slightly better physical function compared with the group that had no treatment at all. Sham acupuncture worked as well as real acupuncture, suggesting the placebo effect may be at work.
