News from the World of Medicine
Read up on the latest medical news and studies: it's crucial to eat fruit, how sitting makes you sad, why marriage may beat cancer, and more.
Why you should chew (not chug) your fruit
People who ate whole fruits—particularly blueberries, apples, and grapes—at least twice a week cut their risk of developing type 2 diabetes by up to 23 percent compared with people who ate them no more than once a month, according to a new study in BMJ. For fruit juice, however, the reverse was true. People who sipped a serving or more a day had up to a 21 percent increased risk of developing the metabolic disorder.
Does sitting make you sad?
Middle-aged women who sat for more than seven hours a day were 47
percent more likely to show signs of depression than those who sat for
four or fewer, Australian researchers found. Those who engaged in no
physical activity were 26 percent more likely to have symptoms of
depression three years later than those who met exercise guidelines.
Sitting for long periods has also been linked to heart disease and type 2
Can marriage beat cancer?
Married people were 20 percent less likely to die from the disease than those who were single, divorced, or widowed, according to a Harvard study of more than 730,000 people published in the Journal of
Clinical Oncology. They were also likelier to get the disease diagnosed at an earlier stage and receive proper treatment. A spouse (or a close partner, friend, or family member) can prod you to seek medical help and support you during grueling chemotherapy, radiation, and other treatments.
New Tylenol warning:
To help combat the risks of acetaminophen overdose, the cap of each Extra Strength Tylenol bottle sold in the United States has a new warning in bold red letters: “CONTAINS ACETAMINOPHEN. ALWAYS READ THE LABEL.” Because the pain reliever is in hundreds of over-the-counter and prescription medications used by nearly 25 percent of adults every week, it’s easy to exceed recommended levels (though more than one third of us don’t realize the risk, according to a ProPublica poll). In fact, acetaminophen overdoses send tens of thousands of people to the emergency room every year and are the most common cause of sudden liver
failure in the United States. Always follow dosing instructions carefully, and check the acetaminophen content of each product when taking more than one drug simultaneously.
Deadly mouth danger
The number of Americans who went to the hospital for dental abscesses increased more than 40 percent from 2000 to 2008, according to a new study in the Journal of Endodontics. Many tooth infections are treatable with prompt care, but delays can be serious (for instance, if bacteria travel to the airway, where they can restrict breathing, or to the brain). Seek treatment for any persistent tooth pain, and get regular dental care to treat tooth decay before an abscess can develop.
Intense workouts squelch eating
Overweight men who did interval workouts—alternating short bursts of high-intensity exercise with brief recovery periods—ate less post-workout and consumed fewer calories the next day than those who exercised at a continuous moderate pace, found researchers at the University of Western Australia. Interval exercisers also had lower levels of ghrelin, a hormone that stimulates appetite.
Down Syndrome may shed light on Alzheimer’s
About half of people with Down syndrome develop symptoms of Alzheimer’s disease by their 50s, and all eventually develop the disease’s trademark brain plaques. (A protein involved in the
formation of the plaques is made by a gene on the 21st chromosome, of
which people with Down syndrome have an extra copy.) Harvard Medical
School and Massachusetts General Hospital researchers have begun a
clinical trial of a drug that seems to stop plaque formation in people
with Down syndrome. These subjects, who don’t yet have symptoms of
dementia, may be an important group in which to study how therapies work
in the earliest stages of the disease, when they are believed to be
