Understanding the heart attack gender gap

We tend to think of heart attacks (and heart disease) as primarily happening to men. That might be because women tend to minimize any heart attack symptoms they experience — and to delay seeking treatment much longer than men. Recent studies on this “heart attack gender gap” have revealed several things that can help make sure every patient with heart disease gets the best treatment possible.

Awareness of the effects of concussions in children and adolescents has risen, along with the frequency of diagnosis. Researchers and other medical professionals are attempting to develop tools such as a risk grading scale, that might be used to better manage the injury and provide the most effective treatment.

Millions of adults in the United States struggle with anxiety, but making the right dietary choices can help. The body’s slower metabolism of complex carbohydrates helps avoid drops in blood sugar, and foods with specific nutrients like zinc, magnesium, and antioxidant substances can ease anxiety as well.

Many children look forward to the warm, mild spring weather — but kids with seasonal allergies (also known as hay fever) might not. Hay fever can interfere with a child’s ability to play outdoors and enjoy the change of seasons, and it can just plain make them feel miserable, too. We’ve listed four tips to help your child cope with allergy season — and they work just as well for adults, too.

Over 35 and expecting: Is it safer to give birth “early”?

For women having children over age 35, the decision to induce labor is usually based on an increased risk of stillbirth. The duration of labor also factors into the decision, as does the possibility that induction could increase the chance of a cesarean birth, though current medical evidence does not necessarily support this assertion.

Running injury? Maybe you’re doing it all wrong

The benefits of regular exercise are well understood, but some forms of exercise carry a higher risk of injury than others. A new study of female runners suggests that an individual’s running style may play a role in susceptibility to injury, but it also raises questions about technique that warrant further study.

Thyroid disease and breast cancer: Is there a link?

Mallika Marshall, MD, Contributing Editor

Researchers have wondered for a long time whether there might be a link between excess thyroid hormone and an increased risk of breast cancer. High levels of thyroid hormone have been shown to mimic estrogen, which fuels many breast cancers. A new study has suggested that there may indeed be a link — but it’s important to put the results into context.

Could lack of sleep trigger a food “addiction”?

Stuart Quan, MD
Stuart Quan, MD, Contributing Editor

Many people cite a lack of “motivation” or “willpower” as the reason that overweight people can’t control their eating habits. But a wealth of evidence has come to light that obesity is linked to insufficient sleep. Most recently, an experimental study has found that restricted sleep can increase the levels of brain chemicals that make eating pleasurable. Could it be that insufficient sleep makes the brain addicted to the act of eating?

FDA warns parents about arsenic in rice cereal

Claire McCarthy, MD, Faculty Editor, Harvard Health Publications

Rice has an unusually high arsenic content — and high amounts of arsenic in the body can increase the risk of cancer and learning difficulties. The FDA has recently proposed an upper limit on the amount of arsenic in infant rice cereal, but it hasn’t yet been adopted. In the meantime, we’ve listed steps you can take to reduce your — and your child’s — consumption of arsenic.

Is there a “best” pain reliever for osteoarthritis?

Robert R. Edwards, Ph.D.
Robert R. Edwards, Ph.D., Contributing Editor

Osteoarthritis can contribute significantly to a reduced quality of life, and many arthritis sufferers have come to rely on pain medication for symptom control. A recent study compared NSAIDs against opioids for pain relief and found no significant difference between them. But as always, the right treatment choice for any individual person depends on their unique medical situation and what works best for them.
