Many people with rheumatoid arthritis (RA) also deal with ongoing depression and anxiety related to their pain and disability. While drugs used to treat the disease help alleviate the joint pain and stiffness, a recent study suggests they may not extend to improving patients' mental health.

The findings, published online June 6, 2018, by Arthritis & Rheumatology, reviewed more than 70 clinical trials and found only a small association between various drugs used for RA, such as adalimumab (Humira), rituximab (Rituxan), abatacept (Orencia), and tocilizumab (Actemra), and mental health outcomes in patients.

If you suffer from low back pain and want to avoid taking strong pain medication, you might want to consult a physical therapist first, suggests a recent study published online May 23, 2018, by Health Services Research.

Researchers reviewed insurance claims for approximately 150,000 adults, ages 18 to 64, who had been newly diagnosed with low back pain. They found that those who first consulted a physical therapist had an 89% lower probability of receiving an opioid prescription compared with those who saw another type of medical provider. They were also less likely to have an MRI or CT scan or to seek out emergency care for their pain.

Pictures may be more effective than words in helping consumers make healthier choices. A new study, published online June 18 by Psychological Science, found that using warning labels that included photos to outline the health risks of sugary drinks appeared to be more effective than written warnings in encouraging people to choose healthier drinks.

Researchers tested two different types of warnings for sugary beverages: warnings with photos and text, and text-only warnings. The warnings were placed near bottled and fountain drinks in a cafeteria at a Massachusetts hospital at different times. During the study period, there were more than 20,000 drinks sold.

What's the secret to living longer? A Harvard study published online April 30, 2018, by Circulation suggests that it may come down to five healthy habits: eating a healthy diet, exercising daily, keeping a healthy body weight, drinking alcohol only in moderation, and not smoking. Researchers combed through information from two large studies that tracked more than 123,000 men and women for about three decades. Scientists estimated that life expectancy for study participants (at age 50) was 79 for women and 75 for men, if they didn't maintain healthy habits. But if they adopted all five habits, life expectancy at age 50 jumped to 93 for women and 87 for men. And following even one healthy habit was associated with a lower risk for dying young. The study is only observational and doesn't prove that healthy habits extend your life. But the findings build on similar research. "It's never too late to make positive lifestyle changes. Even for those who are 70 or older, following a healthy lifestyle such as eating a healthy diet and being physically active can add more years to life," says Dr. Frank Hu, senior author of the study and chair of the Department of Nutrition at the Harvard T.H. Chan School of Public Health.

Encouraging news for people who suffer with migraines: in May, the FDA approved erenumab (Aimovig), the first medication aimed at preventing these debilitating headaches. Current medications to treat migraines were actually designed to control other conditions, such as seizures or an irregular heartbeat; their side effects (like sexual dysfunction and fuzzy thinking) often cause people to skip treatment. Erenumab offers a new approach. Injected once a month, it works by blocking a molecule (calcitonin gene-related peptide) involved in migraine attacks, and compared with other drugs, it appears to have fewer side effects (primarily constipation and injection site reactions). "This drug is for people who have more than four migraines per month, but it won't take migraines away entirely," says Dr. Gad Marshall, a neurologist at Harvard-affiliated Brigham and Women's Hospital. Clinical trials suggest it can reduce frequency by one or two migraines per month, or even more in some people. "For people with frequent debilitating migraines it could be a game changer," says Dr. Lee Schwamm, a neurologist at Harvard-affiliated Massachusetts General Hospital. "But erenumab is expensive, and it will take time to find out if it's effective and safe over the long term."
