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.

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.

The development of vaccines for many once-fatal illnesses has saved the lives of hundreds of thousands of children in the United States. While some parents may have concerns about the side effects of a vaccine, the decision not to vaccinate a child extends the risk of illness to the larger community.

The CDC recently advised all sexually active women of childbearing age, and who aren’t on birth control, to avoid alcohol completely because of potential harmful effects to an unborn child. The science behind the recommendation is sound, but the way it was delivered has raised quite a few eyebrows. In this piece, Dr. Ricciotti examines where the message fell short and describes how she emphasizes shared decision-making and autonomy when she counsels her patients.

Retirement is your reward for a long work life, but research suggests that continuing to work in some way may offer a big payday for your health.

If you are retired, or counting the days, you may want to rethink leaving the workforce behind forever. Recent research has found that seniors who continue to work after age 65 are healthier than retirees.

"For many men, work defines who they are, and they still need to benefit from something meaningful and productive as they age, whether it's in their current job or field or something new," says Dr. William S. Pollack, assistant clinical professor in the Department of Psychiatry at Harvard Medical School. "Work can boost confidence, self-esteem, and happiness, all of which can help men stay active and live longer."

A study in the December 2015 issue of The Lancet Oncology found that a new test, called STHLM3, is more helpful at detecting aggressive cancer than traditional tests for prostate-specific antigen (PSA).

The STHLM3 test is a blood test that analyzes a combination of six protein markers, more than 200 genetic markers, and various clinical data, such as age, family history, and previous prostate biopsies.

Here is one more way men and women are different: research published online Oct. 20, 2015 in Radiology found that male and female hearts do not age the same way.

For the study, researchers reviewed MRI heart scans performed on almost 3,000 older adults, ages 54 to 94, without existing heart disease. (Scans were given 10 years apart.) The scans showed that in both sexes, the main heart chamber—the left ventricle, which fills with and then forces out blood—gets smaller with time. As a result, less blood enters the heart, and less gets pumped out to the rest of the body.

Q: I have always had difficulty sleeping. Since I have taken to heart the advice for good sleep habits, I think I'm sleeping better, but I'm not sure. I'm in bed about 8.5 hours, but am often restless and get up to go to the bathroom a couple of times during the night. Is there a way to compute how much sleep I'm actually getting?

A: Adequate sleep is an important part of health. While the exact amount needed to maximize health and wellness is not totally clear, many experts recommend around seven to nine hours per night. Adequate sleep is associated with memory, improved mood, better weight control, improved diabetes control, greater resistance to colds, and fewer accidents.
