Cell Phone-Cancer Link Seen in Rat Study

An important new study that has linked cell phone radiation to cancers in the brain and heart.

The new research was conducted on rats by the U.S. National Toxicology Program, which exposed rats to radiofrequency radiation that comes from cell phones for about nine hours a day for seven days a week. They found that the exposed rats were more likely to develop cancers, specifically malignant gliomas—a tumor of glial cells in the brain—and tumors in the heart.

The study was reviewed by experts at the National Institutes of Health (NIH), and the authors say more research on the link will emerge in the next couple years. There are some important caveats to the new report. A study in rats is never directly translational to humans. It does, however, give researchers evidence that can lead to further research on the impact cell-phone radiation has on people. The findings were also most statistically significant for male rats.

Other research has seen a link between cell phones and cancer, though research overall remains limited. The World Health Organization’s International Agency for Research on Cancer (IARC) classified cell phone use and other radiofrequency electromagnetic fields as a possible carcinogen in 2011. “This study in mice and rats is under review by additional experts,” the NIH said in a statement about the findings. “It is important to note that previous human, observational data collected in earlier, large-scale population-based studies have found limited evidence of an increased risk for developing cancer from cell phone use.”

Other studies have produced conflicting results. One cohort study in Denmark looked at billing information from 358,000 cell phone users and then compared it to brain-tumor data from a national cancer registry. That study did not find a link between the two. Another recent study published in May looked at incidence of brain cancer in Australia from 1982 to 2013 and did not find an uptick in cancer cases with the introduction of cells phones. Still, other government-funded studies have made connections between cell phones’ electromagnetic fields and changes in brain activity. And a June 2014 study found that radiation from cell phones can lower men’s sperm mobility by 8% and sperm viability by 9%.

The NIH says part of the reason research so far has been inconsistent is that there are various factors that can influence the results of a study. For instance, brain cancers are notoriously difficult to study due to their high mortality rates, and studies are also subject to issues like inaccurate reporting. There are also changes over time in the type of cell phones available as well as how much people use them.

The researchers say this new report is unlikely to be the final word on the possible risks of cell phone radiation, and more data from their research is anticipated to be released in fall 2017.

How Bad Is It to Have a Drink While on Antibiotics?

Q: Is it so terrible to have a glass of wine while on antibiotics?

With a few antibiotics in particular, it is a pretty big deal. Metronidazole, tinidazole, and trimethoprim-sulfamethoxazole should never be mixed with any amount of alcohol because the combo can cause an unpleasant reaction, which may include headache, flushing, a rapid heartbeat, nausea, and vomiting. (FYI: Some cold medicines have alcohol in them, so read labels carefully.)

As for other antibiotics, sipping a small amount of alcohol generally won’t hamper their effectiveness, though some folks may find that the drugs’ usual side effects (upset stomach, dizziness, drowsiness) are enhanced by alcohol.

But there are legitimate reasons why many doctors often warn against mixing the two. If that one drinks turns into several, the excess alcohol can depress your immune system and leave you tired and dehydrated. So if you’re sick enough to need antibiotics, you’re not helping your chances of getting better quickly by downing a glass of wine. Sorry to be a buzzkill!

What to Do If You Spot Blood in Your Poop

Q: I’ve been noticing blood in my poop. Should I be concerned?

I don’t want to alarm you, but you should have this checked out ASAP. How much blood have you been noticing, and what color? And is it mixed in with the stool or on top? These are details that will help your doctor pinpoint where the bleeding is coming from. If you spot bright red or maroon blood on the surface, you may have an anal fissure (a tiny tear), which can happen from passing large or hard stools. While they can be painful, the cuts are typically nothing to worry about and heal on their own within a few weeks. Anal fissures that don’t get better within six weeks may require medicine or surgery—but that’s pretty rare.

Blood on your poop, or bleeding during or between bathroom runs, could also be a sign of hemorrhoids, which are swollen veins in your anus or rectum. You can develop them from a variety of causes, including straining when you go, constipation, or pregnancy, when there’s extra pressure on the veins. Often hemorrhoids can be made less troublesome with dietary tweaks, like drinking plenty of water and adding fiber to help soften stools. In the meantime, your doc may suggest using an over-the-counter hydrocortisone cream to help with the swelling and itchiness.

However, red or darker blood in the toilet or mixed in with the poop might indicate something more serious, such as colon cancer or inflammatory bowel disease (IBD). The most common types of IBD are Crohn’s disease, which involves inflammation anywhere in your digestive tract, and ulcerative colitis (UC), in which the inflammation specifically affects the lining of the colon and rectum. IBD can also cause abdominal pain, fever, and weight loss when it flares up. Mild IBD symptoms can often be controlled by medication, combined with avoiding certain foods (including fatty and high-fiber kinds, as well as dairy), eating smaller and more frequent meals, drinking plenty of water, and exercising. In extreme cases, surgery or additional medications may be required.

Those with Crohn’s disease and UC are also at higher risk of developing colon cancer, which is why it’s important to bring up any blood in your number two with your doctor to figure out the reason behind it and start treating it as quickly as possible.

New York Legislature Passes Bill to Eliminate the ‘Tampon Tax’

Early this year, the “tampon tax” made headlines when California legislator Cristina Garcia introduced an Assembly Bill to exempt feminine hygiene products from sales tax. According to a press release from her office, California women coughed up $20 million annually in taxes for these products, despite them being, in Garcia’s words, a “basic necessity.” Yesterday, New York Governor Andrew M. Cuomo stated that New York State will no longer tax feminine hygiene products, a move that will take effect in the next sales-tax quarter.

Supporters of the bill maintain that tampons and other feminine hygiene products are necessities, and should be treated as other tax-free healthcare items.

Politico reports that the unanimous Senate vote only took “about one minute” on Monday before the bill headed to Governor Cuomo’s office. New York will join a handful of states that lifted the “luxury tax” on these items—a tax many (including President Barack Obama) have called sexist and unjust. Ten other states, including California, are considering similar legislation.

“Repealing this regressive and unfair tax on women is a matter of social and economic justice,” Governor Cuomo said in a statement. “I look forward to signing it into law.“

How to Get Rid of a Muscle Knot

Q: What is a muscle knot, and can massages get rid of them?

It’s not entirely clear what causes muscle knots—but your muscles don’t literally get twisted and tied. Experts think that these muscle adhesions (also called myofascial trigger points) likely result from repeated tension and overuse in a specific area. Hot spots for tightness are the neck, shoulders, and back. Clenching your muscles out of stress or anxiety can create knots, or they can develop due to an injury, poor posture, or even long periods of inactivity.

Massage is in fact one of the best ways to release the tension. If a pro massage isn’t an option, you can DIY it: Put firm pressure on the area, either by lying on a tennis or lacrosse ball or foam roller; hold for about a minute while taking deep breaths. Heating or cooling the area may also help ease the contraction and reduce any associated pain. Taking an OTC pain reliever can also help. If the discomfort won’t go away, check in with your doctor; she may recommend physical therapy.

Surgery Should Be An Option for Diabetics: Experts

New guidelines appearing in the journal Diabetes Care from a group of diabetes experts say that gastric bypass surgery, currently only considered as a way to treat obesity, should also be an option for people with type 2 diabetes, even if they don’t need to lose weight.

That conclusion is supported by the American Diabetes Association and 45 international medical societies, and represents a major shift in the way doctors think about the disease. While diabetes involves imbalances in hormones and metabolism, there’s enough evidence, the doctors say, that bariatric surgery, which involves shrinking the size of the stomach, can not only physically affect how much people eat but also how the body breaks down calories and metabolizes them as well.

RELATED: Gastric Bypass Surgery Highly Effective in Treating Type 2 Diabetes

The new guidelines suggest that for most people diagnosed with type 2 diabetes, if they don’t respond to existing therapies to control their blood sugar levels, bariatric surgery be discussed as an option for them, even if their BMIs are 30-35; currently doctors only consider the operation for weight loss for people with BMI greater than 35 if they also have other health problems such as high blood pressure or sleep apnea.

What the recommendations don’t provide, however, is a precise formula for when people with diabetes who have BMIs that fall between 30 and 35 should turn to surgery. For now, Francisco Rubino, professor of metabolic and bariatric surgery at King’s College London and one the lead authors of the guidelines, says that “surgery would almost never be a front line intervention for the disease,” meaning that people would have to try current therapies, including insulin and sugar-controlling medications, first. They should also try to adjust their diet and lifestyle as well, and only if those don’t work, then consider surgery.

But having surgery as an option, says Rubino, could go a long way toward helping doctors to rule out treatments that don’t work sooner. Until now, they would simply continue to increase the dose of anti-diabetes drugs since they didn’t have much else to give their patients. But now, they wouldn’t have to keep these people on medications and could consider surgery instead. Doctors will need to monitor people with diabetes who decide to get the operation, and not everyone with diabetes may be a candidate for surgery, but Rubino is convinced that more people with diabetes will be able to control their disease with the new recommendation.

3 Ways Your BFFs Can Improve Your Health

We give ourselves credit for plenty of things: nailing a project at work, making killer overnight oats, shaving our legs regularly (well, at least in warm weather). But there’s one thing women ought to take pride in more often, and that’s how much we rock at friendship. Whether single or married, 22 or 78, we know just how to cultivate, appreciate, and enjoy connections with our girls.

While the sexes may equally value friendship, we experience the bond on different levels. “Women tend to have more intimate friendships than men do,” says Irene S. Levine, PhD, clinical professor of psychiatry at New York University School of Medicine and author of Best Friends Forever. A 2015 study of social media profile photos published in Plos One confirmed what many of us have noticed: Guys gravitate toward larger, looser groups of casual buddies, while women prefer fewer besties, forming deeper and more time-consuming friendships. The researchers noted that this pattern is also evident in chimpanzees, suggesting that our pal style “may long predate the evolution of our species.”

But make no mistake—nurture plays a role, says Shasta Nelson, CEO of the friendship-matching site GirlFriendCircles.com and author of Frientimacy. Girls are taught to be masters of positivity (think giving pep talks), consistency (making plans), and vulnerability (sharing emotions). “We live in a society that expects these skills of women,” points out Nelson, “so we’re more practiced at them.”

Not only are we amazing at friendship, but according to science, it’s good for us—both now and as we age. So next time you ditch your family for girls’ night out, tell them it’s medicinal. (Even though, sadly, insurance won’t reimburse you for the round of margaritas.)

RELATED: 21 Reasons You’ll Live Longer Than Your Friends

1. Friends are preventive medicine

It’s more than just your pal bringing over soup when you’re sick: Having good friends can help protect your body from stress. In a series of studies conducted at the University of Virginia, people were faced with the threat of getting an electric shock either while solo or while holding a friend’s hand. MRI scans revealed that in those clinging to a pal, the brain regions that sense danger were significantly less active.

Our besties may even provide a buffer against cancer. In an assessment of 2,835 women with breast cancer in the Nurses’ Health Study, those with no close friends were four times as likely to die from the disease as the women with 10 or more close friends. Other research has shown that the more socially connected people are, the lower their blood pressure when they get older.

That well-being boost may translate to the ultimate payoff: a longer life. A meta-analysis of studies from Brigham Young University found that people with strong social relationships had a 50 percent greater chance of living longer than those with weaker ties. The researchers concluded that a lack of social interaction can pose as much of an early-death risk as smoking and alcoholism, and a higher risk than obesity and physical inactivity. There you go: yet more motivation to quit playing text tag and schedule that catch-up dinner.

2. They protect your mood

Pals not only provide support, they can have Prozac-like powers, too. An English study revealed that people with depression doubled their chances of bouncing back if they had enough friends with “healthy mood.” Data from 4,739 people followed for 20 years in the renowned Framingham Heart Study demonstrated that those with positive peers were likely to become happy in the future. It pays to get out and have fun with a bunch of them, according to a study published in the Journal of Epidemiology & Community Health: Women who have 10 or more friends to socialize with experience better psychological well-being in midlife than those who have fewer. There’s a reason Nelson refers to close friendships as “gyms for our souls.”

3. The right mates make you strong 

Not feeling your workout lately? Rope in a friend, ideally a really fit one. Doing physical activity with a companion who’s in top shape makes you go at it harder than if you exercised with a less in-shape one, per a study from Santa Clara University’s department of psychology. (Although your super-buff pal won’t reap added fitness benefits by working out with you, she will be racking up some serious karma points.)

It’s no wonder, then, that buddies are one another’s best weight watchers. Researchers from the Harvard School of Public Health found that when overweight people were grouped with friends or family as part of a weight-loss program, they lost 6 1⁄2 more pounds and shaved an extra 1 1⁄4 inches off their waists than those who just received info on diet and exercise. Why’s that? The study authors quote an African proverb: “If you wish to go fast, go alone. But if you wish to go far, go together.”
