Now hear this: You may need hearing aids

These tiny devices can improve your communication, your relationships, and even your brain function, but only if you use them.

Age-related hearing loss affects about a quarter of people ages 65 to 74 and half of those ages 75 and older, according to the National Institute on Deafness and Other Communication Disorders. Over all, though, it tends to be more male-oriented.

“By middle age, many men also have hearing nerve damage from long exposure to noises like power tools, music, and guns,” says Dr. Steven Rauch, an otologist with Harvard-affiliated Massachusetts Eye and Ear. Some career choices—like construction, manufacturing, or military service—also contribute.

Women now drink almost as much as men, according to global survey

Alcohol consumption, problem drinking, and alcohol-related health problems are almost as high among women as among men born in the late 1990s.

 

Immediate radiation when PSA levels spike after prostate cancer surgery helps reduce risk of recurrence

After prostate cancer surgery, the patient’s prostate-specific antigen (PSA) is monitored by his doctor via a simple blood test. New research indicates that if the PSA increases following surgery, immediate radiation therapy can reduce the risk of cancer recurrence.

New study recommends immediate radiation when PSA Levels spike after prostate cancer surgery

Following surgery to remove a cancerous prostate gland, some men experience a biochemical recurrence, meaning that prostate-specific antigen (PSA) has become detectable in their blood. Since only the prostate releases PSA, removing the gland should drop this protein to undetectable levels in the body. Detecting PSA could signify that prostate cancer cells are lingering, and […]

Treatment versus monitoring of prostate cancer: Survival rates the same after 10 years

Two new studies add to the evidence that for many men with prostate cancer, if it is detected early and has not metastasized beyond the prostate gland, monitoring the cancer will lead to the same chance of survival after 10 as choosing surgery or radiation. Men treated with surgery or radiation often experience significant side effects. The rates of depression and anxiety were the same in men who opted for monitoring and those who opted for treatment.

HDL cholesterol: How much is enough?

Research suggests that raising good cholesterol beyond a certain point doesn't offer any extra benefit for the heart.

When it comes to cholesterol, it's mostly about the numbers. You want less of the "bad" low-density lipoprotein (LDL) cholesterol and more of the "good" high-density lipoprotein (HDL) kind. This combination is often associated with a lower risk of cardiovascular disease. Sounds simple—and it is, for the most part. But while most attention is spent on driving down bad LDL, you still have to keep your eyes on the good HDL, as some research suggests that after a certain threshold, higher levels don't offer extra protection.

The role of cholesterol

Balancing act

One reason higher HDL may not always be effective is that it needs help to do its job. Another study found that HDL's protective role depends in part on the levels of both LDL and triglycerides (another type of blood fat that helps make up your total cholesterol).

The research, published online May 10, 2016, by Circulation: Cardiovascular Quality and Outcomes, analyzed data over 25 years on about 3,500 people. Researchers looked at people with both low and high HDL levels and those with normal and high levels of LDL and triglycerides.

They found that for optimal protection against cardiovascular disease, there needs to be a balance among all three. Higher HDL (40 mg/dL or higher) helped to reduce cardiovascular disease only when LDL and triglycerides were low (100 mg/dL or less). When LDL and triglycerides rose above 100 mg/dL or 150 mg/DL, respectively, higher HDL had no effect.
