A certain amount of healthy fat is good for your heart.

Low-fat, no-fat, fat-free. Fat has been shamed for so long, it's easy to think there's no place for it in a heart-healthy diet. But the opposite is true. "It's a myth that lowering fat intake is healthy," says Dr. Frank Sacks, professor of cardiovascular disease prevention at the Harvard T.H. Chan School of Public Health. "The key is to use more healthful unsaturated fats and less of the detrimental saturated fats."

The good and the bad

To understand the role of fat in heart health, you first have to look at where it's found in food. There are two types of fat: saturated and unsaturated.

The erectile dysfunction drugs collectively known as phosphodiesterase type 5 (PDE5) inhibitors, such as sildenafil (Viagra), may not cause melanoma, the most dangerous form of skin cancer, according to a study published online May 19, 2017, by the Journal of the National Cancer Institute.

In 2016, the FDA put PDE5 inhibitors on its watch list of medications with possible safety issues after some studies suggested they might increase the risk for melanoma. In response to the FDA's action, researchers analyzed data from five large-scale studies of the issue, involving 866,049 men, published between 2014 and 2016.

The results of two studies found that using the drug abiraterone in combination with other hormonal therapy drugs to treat aggressive prostate cancer produced more favorable results than the first-line therapy alone.

The latest guidelines suggest you should have an engaged conversation with your doctor about PSA testing.

An annual prostate-specific antigen (PSA) test to check for signs of possible prostate cancer sounds innocent enough, but new guidelines suggest the test offers few long-term benefits, and substantial possible harm.

The updated guidelines from the U.S. Preventive Services Task Force (USPSTF), published online April 11, 2017, by The Journal of the American Medical Association, reinforce the organization's 2012 conclusion that PSA screenings have only a small potential benefit for reducing the chance of dying of prostate cancer for men ages 55 to 69 � while exposing them to possible overtreatment and side effects from biopsies, radiation, and surgery.

Staying engaged in life as you age is essential for your health.

"Men have spent a good deal of their earlier life focused on reaching goals, from career advancement to self-improvement," says Susan Flashner-Fineman, the Vitality 360 Wellness Coaching Program coach at Harvard-affiliated Hebrew SeniorLife. "As you get older, you may not recognize the need for accomplishments, yet they are crucial to keeping your mental and physical skills sharp. You want your remaining years to be good ones, so what do you want them to look like? Goal setting can help you get there."

Erectile dysfunction (ED), once shrouded in secrecy, is now in the spotlight, thanks to high-profile advertisements for drugs like Cialis, Viagra, Levitra, and Stendra. But despite this greater awareness of ED, many men � and women � don't really know much about this condition. Here are four things to know about ED.

1. ED is often the result of diseases or conditions that become more common with age. It can also be a side effect of the medications used to treat them. Other possible causes of ED include prostate surgery, stress, relationship problems, and depression.
2. Other age-related factors besides disease can also affect a man's ability to have an erection � for example, with age, tissues become less elastic and nerve communication slows. But even these factors don't explain many cases of ED.
3. Cardiovascular disease is a common cause of ED. Clogged arteries (atherosclerosis) affect not only the blood vessels of the heart, but those throughout the body as well. In fact, in up to 30% of men who see their doctors about ED, the condition is the first hint that they have cardiovascular disease.
4. Intriguing findings from the Massachusetts Male Aging Study suggest there may be a natural ebb and flow to ED � that is, for some men, trouble with erections may occur, last for a significant amount of time, and then partly or fully disappear without treatment.

Regardless of the cause, ED often can be effectively addressed. For some men, simply losing weight and exercising more may help. Others may need medications, and there are other options available as well. Given the variety of therapies available, the possibility of finding the right solution is greater than ever.

Charlie Schmidt A standard approach for treating aggressive prostate cancer is to give therapies that block testosterone, a tumor-stimulating hormone. Should initial hormonal therapies fail, doctors can switch to other drugs that suppress testosterone in different ways. One of them, a drug called abiraterone, has been shown to significantly extend lifespans in men who have […]

Charlie Schmidt In 2012, the US Preventive Services Task Force (USPSTF) took the unprecedented step of recommending against prostate cancer screening for all men, regardless of age, race, or family history. Now this influential group of independent experts is reassessing its position based on more recent data. Instead of discouraging screening altogether, the UPSTF is […]
