What is the test?

Video-assisted thoracic surgery (VATS) is a type of surgery that enables doctors to view the inside of the chest cavity after making only very small incisions. The doctor can examine the outside surface of the lung and the inner surface of the chest wall through a camera attached to the scope. Abnormal appearing areas on the lung surface can be biopsied.

VATS also provides relatively easy access to taking a biopsy of the lung.  This may be needed to diagnose the cause of abnormalities on a chest x-ray or to determine the specific infectious agent responsible for pneumonia that is not getting better on antibiotics.

If you’re like most people with hearing loss, you’ll probably find that it takes time to accept the idea that you need a hearing aid, and you may be unhappy when your audiologist recommends that you get not one, but two. Chances are that your first question will be, “Is it normal to get two hearing aids?” And then, “Do I really need two?”

If you have hearing loss in only one ear and normal or nearly normal hearing in the other, then one hearing aid is all you need. But most people have hearing loss in both ears, especially if the loss is age-related. (You may have one ear that’s better than the other, but chances are both will be in the same ballpark.) In that case, research and experience suggest that you’ll ultimately be more satis­fied with two hearing aids.

You have a brief window to seek treatment.

Everyone's hearing naturally declines with age, and people often have one ear that hears better than the other. But if hearing loss appears suddenly in one ear for no apparent reason, you may have experienced sudden sensorineural hearing loss, or SHL, a kind of nerve deafness.

There are about 66,000 new cases of SHL per year in the United States, according to research in the August 2019 issue of Otolaryngology — Head and Neck Surgery. But these numbers are hard to come by, since the condition may be underdiagnosed.

Q. My mother is in her late 80s. She received the flu vaccine this year, but I heard that it won't be as effective because of her age. Is this true?

A. The flu vaccine can be less effective in elderly adults. That's because the flu vaccine works by priming the body's own immune system to mount a response to the virus if it's encountered. Older adults may have weaker immune systems, and therefore a weaker immune response to the vaccine.

Palliative care improves comfort and quality of life for people with serious illness and their families, yet many people who could benefit from these services are not taking advantage of them

Ignoring symptoms of this carpal tunnel syndrome can lead to permanent nerve damage.

First, you may notice tingling or numbness in your fingers that comes and goes. Over time, the sensations may get worse, lasting longer or even waking you up at night. Eventually the pain and numbness might even make it hard to grip things like a fork, a pen, or other objects.

If you're having these symptoms, it could be carpal tunnel syndrome, which occurs when the median nerve — which runs down your arm and into your hand — is compressed by a ligament that crosses over it as it passes through a narrow space in the wrist known as the carpal tunnel.

Even after cataracts are successfully removed, a new problem may bring back the same symptoms.

When the clear lens inside your eye becomes cloudy, it's called a cataract. Cataracts are a common cause of poor vision in older age, with symptoms such as blurry vision and the appearance of halos around lights. Doctors can restore your vision by removing the cloudy lens and replacing it with an artificial lens implant.

But sometimes a side effect of the procedure triggers the return of cataract symptoms. The side effect is called posterior capsule opacification, also known as a secondary cataract. "This affects about a third of people who have cataract surgery. It's one of the reasons we ask people to come back for follow-ups," says Dr. Roberto Pineda, a cataract surgeon at Harvard-affiliated Massachusetts Eye and Ear.

About half of all people in the United States living with a diagnosis of HIV (human immunodeficiency virus) are age 50 or older. But new data from the CDC suggest most Americans have never been tested for the virus (which causes AIDS, the late-stage phase of HIV infection). According to the June 28, 2019, Morbidity and Mortality Weekly Report, less than 40% of people in the United States have had an HIV test, even though the CDC recommends routine testing at least once for everyone age 13 to 64. The CDC notes that older adults sometimes aren't tested for HIV because they don't consider themselves at risk for infection or because their health care providers don't offer them the test. Older people may also mistake late-stage HIV symptoms, such as weight loss and frequent illness, for signs of normal aging. Those symptoms occur because HIV attacks the body's immune system. But a delay in diagnosis allows the virus to cause more damage. That's unfortunate, since medications can keep the infection from progressing.

If you haven't had an HIV test, talk to your doctor about whether it's right for you, no matter your age, especially if you are sexually active or have had more than one sex partner.

Q. My doctor recently told me I have prediabetes. Is this condition reversible?

A. Yes, it is possible to reverse prediabetes. Prediabetes is a condition that affects millions of Americans. The CDC estimates that as many as one in every three American adults has the condition, which is defined as having blood sugar that is elevated, but not high enough to meet the threshold for diabetes. Left untreated, prediabetes can progress to diabetes, a condition in which your body is not able to absorb glucose for energy properly, causing blood sugar to rise. If it's not managed properly, diabetes can lead to a number of health problems, from heart attack and stroke to blindness, kidney problems, and infections, among others. But making some lifestyle changes can reduce the risk that your prediabetes will develop into diabetes.
