Unless you have symptoms of a heart problem, taking a cautionary look under the hood is unlikely to help—and could even be harmful.

As estrogen levels fall during menopause, a woman's risk of depression triples. Estrogen therapy helps elevate mood for some women, but a study published in the May 27, 2015, issue of JAMA Psychiatry has indicated that depression may recur once women stop using estrogen.

A team of researchers at the National Institute of Mental Health studied 56 postmenopausal women, 26 of whom had a history of depression and 30 who had never been depressed. The women were each given an estrogen patch to wear for three weeks and tested for depression. None were depressed.

Men who want to live longer would be wise to remain physically active as long as possible, according to a long-term study of aging in older men reported in the British Journal of Sports Medicine.

In 1972–73, the Oslo Study recruited nearly 15,000 Norwegian men ages 40 to 49. In 2000, the surviving participants filled out a survey about their daily physical activities. This included everything from couch-potato time in front of the TV to vigorous athletic workouts several times a week.

Active and retired servicemen with prostate cancer can get access to clinical trials, experimental therapies, and state-of-the-art care through the Department of Defense’s Center for Prostate Disease Research (CPDR).

Q. I heard that there is a new stool test for colon cancer screening. Can this test replace colonoscopy for me? I am 68 years old with no history of colon problems, and my last colonoscopy was normal.

A. Among screening tests for hidden colorectal cancer, colonoscopy remains the "gold standard" because it's the most effective technique for detecting colon cancers and simultaneously provides an opportunity to remove any precancerous growths (polyps). The new DNA-based stool test (Cologuard) is less invasive and inconvenient than colonoscopy and finds more cancers and polyps than older stool tests, but it does not entirely eliminate the need for colonoscopies.

Early detection and proper use of eye drops are essential to preventing vision loss.

Glaucoma is a leading cause of irreversible blindness and is more common with aging. The condition affects peripheral vision at first, but eventually becomes more widespread. Treatment with daily eye drops helps to slow the process, but it's best to start early. "Glaucoma tends to be like a snowball," says Dr. Brian Song, a glaucoma specialist at Harvard-affiliated Massachusetts Eye and Ear Infirmary. "It's easier to control it early than if you wait for it to build momentum."

An approach called active surveillance allows some men with low-risk cancer to delay the decision to treat.

Emergency rooms, urgent care clinics, and retail clinics offer immediate care. Your symptoms determine which to use.

You've probably had an illness or injury that you weren't quite sure how to handle. Maybe it was a rattling cough, a finger slammed in a car door, or a rash crawling up your arm. If you can't get in to see your doctor, you have a few options for immediate treatment—the clinic at the nearby shopping mall, an urgent care center, or the emergency room at the nearest hospital. How do you decide which one to go to?

Q. The article in your December 2014 issue about women's waistlines expanding the past few years intrigued me, because I have experienced an increase, and I have not gained weight. My theory is that the styles of the past few years—pants riding low on the hips, no belts at the waist, and loose shirts—may have caused my waist to increase from 24 to 25½ inches. I am 59 years old, so it also could be aging in general, but I still think the belted styles kept women smaller. Am I right?

A. There is no evidence that the physical effect of wearing a belt influences waist circumference. At best, wearing a belt is one way to keep tabs on your waistline. While having to loosen their belt a notch may drive some women to re-examine their diet and exercise routines, it doesn't sound as if you need to do that. I think your alternative explanation that aging is responsible is more likely to be true.
