You may have heard of the 鈥減lacebo effect,鈥� in which people taking an inactive drug as part of a study actually experience an improvement in their symptoms. As it turns out, the placebo effect still exists if you tell people they鈥檙e taking a placebo. This 鈥渙pen-label placebo鈥� strategy doesn鈥檛 work for every condition, of course, but it鈥檚 a promising way to relieve many common symptoms without medication.

Doctors recently discovered a gene in E. coli bacteria that makes it resistant to an antibiotic that is typically used when other drugs fail. This new finding suggests that effectiveness of last-resort antibiotics is at risk. As more bacteria evolve to 鈥渙utsmart鈥� antibiotics, scientists are increasingly concerned about infections caused by 鈥渟uperbugs鈥� that cannot be treated with existing antibiotics.

The results of the 2015 National Youth Risk Behavior Survey, suggests that few teens are smoking cigarettes, having sex, getting into physical fights, and drinking less soda. This good news is tempered by concerning trends, for example fewer adolescents use condoms when they do have sex, and more of them are trying e-cigarettes.

For years, many kids could skip the traditional flu 鈥渟hot鈥� 鈥� along with the tears 鈥� and still be protected by the nasal spray vaccine also known as the LAIV (live attenuated influenza vaccine). But not this year. Studies now show that the nasal vaccine is quite ineffective, and pediatricians are starting to change their flu recommendations from a nose squirt to a shot.

Farmers鈥� Markets hold many benefits for you and your community. The produce is fresher, and there are no 鈥渃enter鈥� aisles to tempt your sweet tooth. Many farmers鈥� markets even offer cooking classes to increase your dinnertime variety. Researchers at the Harvard T.H. Chan School of Public Health saw a decrease in soda consumption and an increase in vegetable consumption among those who frequented farmers鈥� markets this past year.

Miscarriages can be devastating 鈥� especially for women who experience recurrent miscarriage, defined as three or more in a row. Doctors used to give these women supplements of progesterone, a hormone that helps maintain a healthy pregnancy. However, a recent study has confirmed that these supplements don鈥檛 improve pregnancy outcomes. For those who experience recurrent miscarriage, the best solution may be to simply keep trying.

Research suggests that super-sizing our meals doesn鈥檛 just create problems for adults鈥撯�� when we increase the amount of food that infants and children eat, they gain weight. This weight gain during infancy can lead to over-weight children, and over-weight children are more likely to become over-weight adults. In order to make sure infants and children are a healthy weight, keeping the portion sizes kid-friendly is key.

How many times your heart beats per minute when you’re resting 鈥� also known as your resting heart rate (RHR) 鈥� can provide important clues to your current overall health and even predict possible future health problems.

As it turns out, the things your doctor spends so much time focusing on at your yearly check-up account for just 10% of your health needs. Over half of the total “picture” of your health comes from social, environmental, and behavioral factors. This means that people who have unmet environmental needs 鈥� such as being unable to afford healthy food 鈥� suffer real consequences to their physical health. We’ve described one initiative that aims to change that.

We typically think of heart attacks as sudden, chest-clutching agony. But the reality is that nearly half of all heart attacks have no symptoms at all and go completely unnoticed by the people experiencing them 鈥� and, alarmingly, these “clinically silent” heart attacks are nearly identical to more overt heart attacks in terms of the damage they cause and the risk to a person’s future health.

You probably know that smoking has enormous consequences for your health. One of the most common is chronic obstructive pulmonary disease (COPD), a disorder involving damage to the lungs. If you smoke, but you don’t have COPD, you may be tempted to think your lungs are relatively unharmed 鈥� but a recent study suggests that some smokers without COPD might still suffer lung damage.

Like many of us these days, doctors are feeling the pressure of being asked to do more work in less time. This burnout is a big problem for both doctors and their patients, and it has big consequences 鈥� some obvious, some less so. In this post, Dr. Adelman explores the relationship between physician burnout and another big problem facing the country 鈥� the opioid epidemic.
