A painful, blistering rash known as shingles may temporarily increase a person's risk of a stroke or heart attack, according to a study in the Dec. 15, 2015 PLOS Medicine. Also known as herpes zoster, shingles results from a reactivation of the virus that causes chickenpox, which most adults had during childhood.

For the study, researchers analyzed the records of more than 67,000 people ages 65 and older diagnosed with shingles and either a heart attack or stroke from 2006 through 2011. They then compared the rates of cardiovascular events before and after a shingles attack. In the first week after a shingles diagnosis, the risk of a stroke rose 2.4 times and the risk of a heart attack increased 1.7 times compared with baseline risk.

Turmeric, coriander, and cumin may boost your health and breathe new life into tired dishes.

The health benefits of foods such as berries, broccoli, and salmon are well known. But your kitchen's spice rack may also hold some secret weapons against conditions such as inflammation, heart disease, cancer, and more. "Spices are underused, but it would be very easy to take advantage of them and improve health," says Dr. Lipi Roy, an internal medicine physician at Harvard-affiliated Massachusetts General Hospital.

There are few large randomized trials that demonstrate spices' health effects. But many studies in animals suggest that several spices offer benefits. So instead of flavoring your food with salt and butter, which can contribute to high blood pressure and heart disease, consider using the following spices.

Thorough risk assessment and family assistance may help you take them more safely.

Prescription pain pills such as oxycodone (Oxycontin) and hydrocodone (Vicodin) are in a class of drugs known as opioids. They're typically used to treat severe pain after surgery, and sometimes to treat chronic pain. But these drugs come with many risks, including addiction. Does that put you at risk if you take opioids? "You have to look at it on a case-by-case basis," says Dr. Hilary Connery, an addiction psychiatrist at Harvard-affiliated McLean Hospital.

Risks and benefits

Opioids are powerful painkillers that block messages of pain to the brain and decrease the body's perception of discomfort. They may also create a feeling of euphoria. Opioids are especially useful in the short term, such as the initial weeks following joint replacement. Common side effects include nausea, itching, drowsiness, or constipation.

You may assume that there aren't any symptoms for sudden cardiac arrest (SCA), the deadly condition that occurs when your heart suddenly stops pumping. But a study published Jan. 5, 2016, in Annals of Internal Medicine suggests that warning signs are common and often ignored. The most common warning signs were chest pain, breathlessness, palpitations, lightheadedness or fainting, nausea, and vomiting.

Researchers looked at the health information of more than 800 people who experienced SCA, mostly middle-aged men, and discovered that about half of the people had warning signs during the four weeks leading up to SCA and even 24 hours before their hearts stopped. But most of those with warning signs ignored the symptoms. Thirty-two percent of those who called 911 before SCA survived, compared with only 6% among those who didn't call for help. That's because many of the symptoms that led people to call 911 occurred in the hours just before the SCA, so these people were likely to be in a medical care setting when their hearts stopped.

Exercises, lifestyle change, medications, and procedures can alleviate incontinence and give you your life back.

A leaky bladder or a sudden urge to go to the bathroom is uncomfortable andembarrassing. But you can take steps to alleviate the problem. "Some people tell me they would have sought treatment sooner if they'd known it was this simple," says Dr. Anurag Das, director of the Center for Neurourology and Continence at Harvard-affiliated Beth Israel Deaconess Medical Center.

Lifestyle changes

One of the first lines of defense is pill-free and costs nothing: lifestyle change. For urge incontinence (see "Types of incontinence"), you can try timed voiding (urinating on a schedule) and bladder guarding, which teaches you to cope with triggers that set off the urge to go, such as washing dishes or hearing water. "You squeeze your muscles to hold in urine before a trigger, which sends a message to the brain that this is not the time to go," says Dr. Das. Other lifestyle changes include watching fluid intake; quitting smoking, to reduce coughing and pressure on the bladder; and minimizing bladder irritants such as caffeine, alcohol, and carbonated drinks.

Ask the doctor

Q: My eyesight is declining, but my eye doctor tells me I do not have any serious eye problems. Are there any vitamins or supplements I can take to protect my eyes?

A: Based on the most recent research, there is no proven vitamin cocktail to prevent vision loss. The most common causes of vision loss as you grow older are cataracts and age-related macular degeneration (AMD). Since cataracts can be treated with simple surgery, much of the attention for prevention of vision loss has focused on macular degeneration. Initially, there was excitement about antioxidant vitamins, since a combination of vitamins A, C, and E delayed progression of AMD in previously diagnosed individuals. However, the Age-Related Eye Disease Study showed no benefit from antioxidants in people who did not already have AMD. A single study in women (average age 64) reported that a combination of vitamins B₆, B₁₂, and folate reduced the development of AMD over a seven-year period. But this study has not been replicated, and it hasn't been done in men, which makes it hard to recommend these supplements.

These uterine tumors, though usually benign, can cause heavy bleeding, cramps, and pregnancy complications. But there are several good options for treatment.

Fibroids—smooth muscle tumors of the uterus—are common, affecting as many as 75% of women. They are rarely cancerous, and they cause symptoms in only about 20% of the women who have them. However, if you're one of those with symptoms like heavy menstrual bleeding, bad cramps, pelvic pressure, constipation, or frequent urination, you know how fibroids can disrupt your life. Even if they don't cause symptoms, they may grow into the uterine cavity, potentially complicating a pregnancy and raising the risk of miscarriage.

"Managing uterine fibroids depends on several factors, such as a woman's symptoms, whether or not she wants to have children, her age, and her personal preferences," says Dr. Hye-Chun Hur, director of the Division of Minimally Invasive Gynecologic Surgery at Harvard-affiliated Beth Israel Deaconess Medical Center and associate medical editor of Harvard Women's Health Watch.

A Spanish clinical trial of 400 people—two-thirds of whom were women—has indicated that waiting to fill an antibiotic prescription may be a good idea for people with sniffles, coughs, sore throats, and other respiratory symptoms.

Researchers recruited volunteers who sought care for respiratory symptoms in primary care clinics throughout Spain. The volunteers were randomly assigned to four equal groups. One was given antibiotics and told to take them immediately. Another was sent home without antibiotics but told to return to the clinic if they hadn't improved after several days. The two remaining groups were told to wait to take antibiotics—one was asked to return to the clinic to get their mediation after three days; the other group was given an antibiotic, but told to take the medication only if their symptoms hadn't improved after five to 10 days.

Tau proteins, and not necessarily beta-amyloid, may be the key to unlocking a viable treatment.

Alzheimer's disease affects more than five million people, and that number is expected to more than double by 2050. While there is no cure, attention has refocused on what many researchers believe is a major player in Alzheimer's: tau proteins.

Is heart disease in your genes? And if so, can you do anything about it?

Cardiovascular disease continues to be the No. 1 killer of men, and while strides have been made to reduce the risk of heart attack and stroke, one area that remains elusive is genetics.
