If you suffer from the common skin condition eczema, you may have a higher risk of breaking a bone compared with someone who doesn't have the condition, according to a study published in the February 2020 issue of The Journal of Allergy and Clinical Immunology. The study authors found that the 500,000 people in the study who had eczema, which causes itchy dry patches on the skin, were 7% to 18% more likely to break a bone in the wrist, hip, pelvis, or spine when compared with more than 2.5 million participants who didn't have the condition. Researchers said it's not clear if this elevated fracture risk was related to the eczema itself or whether other factors caused the association. For example, the increase in risk could have been related to medications people took to treat eczema. Even so, if you have eczema, the study authors say it may be worth asking your doctor whether you might be at increased risk for osteoporosis.

Scientists continue to explore the health benefits versus risks of aspirin therapy. One new analysis suggests that taking aspirin may protect against several types of digestive tract cancers. The results were published online April 1, 2020, by Annals of Oncology.

Researchers examined 113 observational studies of cancer in the general population. They found that individuals who took aspirin regularly — at least one or two tablets a week — had significantly lower rates of cancers of the bowel, stomach, gallbladder, esophagus, pancreas, and liver, compared with people who did not take aspirin.

The latest recommendations focus on newer medications, lifestyle changes, and procedures.

If you have heart disease, following a healthy diet and getting regular exercise should be a top priority. Both habits can help you reach and stay at a healthy weight and lower your blood pressure and cholesterol level. Chances are you'll also need to take medications to further improve those common heart-related risk factors. But if you also have diabetes, you may need even more aggressive treatment, according to new advice from the American Heart Association.

The recommendations, published May 12, 2020, in the journal Circulation, detail the latest evidence about treatments for people with both heart disease and diabetes. Diabetes, which affects about one in 10 adults, doubles the odds of having a heart attack or stroke (see "Why is diabetes hard on your heart?").

Many lifestyle factors can influence the development of atrial fibrillation, and doctors now better understand the importance of these factors in treating afib. Those who are at risk of developing afib can take action to improve their health, and in some cases they may be able to reduce their symptoms.

Tennis elbow is the common term for lateral epicondylitis, an inflammatory condition of the tendon that connects the extensor muscles of the lower arm to a bony prominence on the outside of the elbow called the lateral epicondyle. The condition causes pain at the point where the tendon attaches to the epicondyle. The pain may radiate to the forearm and wrist, and in severe cases, grip strength may lessen. It can become difficult to perform simple actions like lifting a cup, turning a key, or shaking hands.

As many as half of all people who play racket sports have the condition, but most people who have tennis elbow didn't acquire it by playing tennis, squash, or racquetball. It can result from any activity that involves twisting or gripping motions in which the forearm muscles are repeatedly contracted against resistance, such as pruning bushes or pulling weeds, using a screwdriver, or playing a violin. Tennis elbow is an occupational hazard for professional gardeners, dentists, and carpenters.

An increasing number of Americans have a blood abnormality that indicates autoimmunity, which means their immune system has created antibodies that could work against the body's own cells, according to a study published April 7, 2020, in Arthritis and Rheumatology. Autoimmunity can lead to autoimmune diseases such as rheumatoid arthritis or lupus, although the study authors said they didn't look to see whether the prevalence of diagnosed autoimmune diseases also rose during the same period of time.

The researchers found a rise over two decades in the number of people who had positive antinuclear antibody (ANA) blood tests, a signal of autoimmunity. They used blood samples taken from 14,211 people ages 12 and older, as part of the U.S. National Health and Nutrition Examination Survey. In samples taken in the period 1988 to 1991, ANA prevalence was 11%. It rose slightly to 11.5% for the 1999–2004 time period, and to 15.9% in the 2011–2012 period. Comparing differences in gender, race and age, the largest increases in positive ANA tests occurred in men, non-Hispanic whites, adolescents, and adults ages 50 and older.

Q. I occasionally get an excruciating leg cramp that wakes me from sleep. What causes leg cramps, and how can I prevent them?

A. Although nocturnal leg cramps can strike people at any time of life, they become more frequent with age. Among people older than age 50, about half report having leg cramps, a third say they are awakened at night by them, and 15% report having cramps about once per week.

Men need to manage their bone health as much as women do.

Most people think of osteoporosis as a women-only health problem, but older men also need protection from this bone-weakening disease.

About one in four men older than 50 will break a bone because of osteoporosis during his lifetime, according to the National Osteoporosis Foundation. And research has found that compared with women, older men are more likely to die following a fracture related to osteoporosis.

Ask the doctor

Q. I know doctors and scientists are very busy dealing with COVID-19. Is the need to care for, and do research on, COVID-19 affecting the care of and research on other important diseases?

A. You're right: the COVID-19 pandemic has consumed and disrupted medical care and medical research in the United States and around the world.

Ask the doctors

Q. A friend told me that I should be screened for hepatitis C. I'm not in a high-risk group. Is this really necessary?

A. If you're an adult younger than 80 years old, the answer is yes. In March, a government health advisory group, the U.S. Preventive Services Task Force (USPSTF), revised its earlier position and now recommends that all people ages 18 to 79 be screened for this "silent" virus. Prior to this change, the USPSTF recommended only that only high-risk individuals or adults born between the years 1945 and 1965 be screened. Hepatitis C can attack the liver and lead to serious liver damage and liver cancer. The condition is curable if detected. But people often don't consider themselves at risk and are unaware that they are infected, because they typically don't have symptoms.
