You can protect yourself against superbugs
Some simple preventive measures can keep antibiotic-resistant bacteria at bay.

Although the Zika virus got more publicity throughout the summer, another—and even scarier-sounding—microbe also made headlines. Dubbed a new "superbug," strains of E. coli resistant to the antibiotic colistin were found in the United States. Colistin is a drug often used when others fail to control a bacterial infection. Fortunately, the bacteria weren't resistant to other antibiotics, which cleared the infections. "Although this particular case of antibiotic resistance may not be as dire as the media made it sound, in general these increasingly high-level resistances are an enormous problem," says Dr. Sarah Fortune, professor of immunology and infectious diseases at Harvard T.H. Chan School of Public Health.
Why superbugs are such a problem
Like other forms of life, bacteria are always evolving to become stronger and survive longer. One of the ways they increase their chances of survival is to acquire genes that help them resist threats—including natural enemies like viruses and man-made weapons like antibiotics. These genes can spring up within a bacterium through mutations and are passed down to subsequent generations of the microbe. In addition, they can be found on rings of DNA called plasmids, which can be transmitted to other types of bacteria, enabling the resistance to spread wider and faster. The E. coli strains discovered in 2016 raised concern because they carry the colistin-resistance gene on plasmids and thus have the potential to transfer the plasmids to bacteria that are already resistant to several other antibiotics.
Can I take an expired medication?
Most drugs remain potent after their expiration dates. You may want to move it to the refrigerator, though, because drugs stored in cool temperatures usually remain potent longer.

Why you should heed a ministroke
Transient ischemic attacks, or TIAs, can signal an impending stroke, but prompt care can minimize damage.

Have you ever experienced a brief episode when your body seemed to be a little off—your vision was blurry, your speech slightly slurred, or one side of your body felt weaker than the other? If so, you may have experienced a transient ischemic attack (TIA), says Dr. Natalia Rost, a neurologist at Harvard-affiliated Massachusetts General Hospital. She notes that many women may assume they have suffered a migraine and get back to life as usual once the episode has passed. In fact, a TIA is a serious medical issue and warrants getting immediate treatment.
Immediate treatment is key
Having a TIA is usually a sign that you may have already endured a few "silent strokes"—interruptions of blood flow to the brain—and may have accumulated some brain damage as a result, Dr. Rost says. However, getting prompt attention for a TIA can significantly reduce your chance of having a major stroke and incurring greater damage.
A team of French researchers reported in April 2016 that people who received care from a stroke specialist within 24 hours of a TIA had only a 4% risk of having a major stroke within the next three months, compared with the average risk of 12% to 20%. Recent studies also show that people who got prompt treatment from stroke specialists in the hospital or clinic were much more likely to get the appropriate follow-up treatments, including aspirin, blood thinners, and blood pressure medication. "Just as getting prompt treatment for chest pain minimizes damage from a heart attack, getting help for a TIA diminishes the effects on the brain," Dr. Rost says.
Yet studies have shown that women aren't as likely as men to get brain-sparing treatments. A 2013 study indicated that gender discrimination wasn't the problem; women were less likely than men to seek help within four hours of the start of symptoms, when clot-busting therapies are most effective. Women who sought help within four hours received the same treatment as men did.
Why white matter really matters
What you should do
Dr. Rost suggests doing everything you can to minimize white-matter damage—controlling your blood pressure, cholesterol, and blood glucose are important. So is a lifestyle that includes regular exercise, a healthy diet, and not smoking. "While it's important to get help for a TIA, it's better to avoid one altogether," Dr. Rost says.
Beverage temperature tied to cancer risk
Beverages consumed at temperatures above 150° F may contribute to esophageal cancer.
