Knee replacements are successful for 80 percent of recipients, yet many assume the success rate should be higher. Those who are not successful often are bitterly disappointed. However, patients and physicians can take steps to avoid a bad result. New techniques also offer much faster recovery. Experts discuss.

Many people have questions about their bodies that seem so silly, they never bring them up with their doctors. While the answers are sometimes humorous, often they are more complicated and important than we imagine. An expert physician/writer discusses.

In the first two months of this year, the United States has had more cases of measles than we had in all of 2017. Experts say it’s because some parents still believe the disproven claim that the measles vaccine causes autism, so they don’t have their kids vaccinated. But how much evidence will it take to convince them? Yet another study, this one on more than a half-million people and published in the Annals of Internal Medicine, finds there is absolutely no link between the MMR vaccine and autism.
If you don’t get enough sleep during the week, your body can’t catch up over the weekend. A new study in the journal Current Biology shows that even when people sleep in as long as they want on Saturday and Sunday, chronic sleep deprivation during the week causes metabolic changes leading to weight gain and a higher risk for diabetes. Researchers suggest the long-term effects of chronic sleep loss are severe enough that people need to start prioritizing sleep.
And finally, might it be possible that the secret to a long life is coffee and alcohol? It sure sounds that way, according to the results of the ’90+ study’ at the University of California-Irvine. Researchers say one of their main findings is that people who drink alcohol and coffee live longer than those who don’t. People who made it to at least 90 years old also tended to be overweight in their 70s, while those who died sooner were normal weight or underweight.

Does the world’s most widely used broad-spectrum weed killer cause cancer? A number of studies have come to different conclusions. But now a comprehensive new analysis in the journal Mutation Research – Reviews in Mutation Research has looked at all the evidence, including a test of more than 50,000 licensed pesticide applicators. The study concludes that yes, the chemical glyphosphate raises the risk of non-Hodgkin lymphoma by as much as 41 percent. Glyphosphate is the primary ingredient in the weed killer Roundup.
If you’re a middle-aged man and can do 40 pushups without stopping, you’re at a 96 percent lower risk of heart disease than those who can do only 10. A study in the journal JAMA Network Open finds that the pushup test may be the most reliable and inexpensive way to judge a man’s heart health over his next 10 years, even more reliable than treadmill tests. But if you can’t do 40 pushups, don’t despair. Heart disease risk is lower to some degree as long as you can do 11 or more.
And finally… gardeners will tell you that playing in the dirt makes them happy, and the reason? There’s a natural antidepressant in soil that acts much the same way as Prozac, but without side effects. A study in the journal Neuroscience shows that gardeners inhale a soil microbe called Mycobacterium, which acts to raise serotonin in the brain, increasing feelings of relaxation and happiness for as long as three weeks.
New surveys show that as many as 80 percent of people omit information, stretch the truth or outright lie to their doctors. Experts discuss why it happens, consequences, and methods that might reduce the amount of less-than-truthful answers to doctors’ questions.
