Millions of Americans take a low-dose aspirin every day in hopes of preventing a heart attack or stroke. But now the American College of Cardiology and the American Heart Association say to stop taking it if you have no history of heart attack or stroke. The new recommendation comes in the wake of a major study showing that a daily aspirin does nothing to prolong life and increases the risk of gastrointestinal bleeding. Experts say doctors should limit aspirin to people at high heart risk who also have a low risk of bleeding.
Nobody likes to get caught in traffic caused by road repairs but a new study in the International Journal of Sustainable Transportationfinds that preventive road maintenance saves a lot of money, time, and pollution. Researchers say performing maintenance when a road is in its early failure stage ends up saving 10 to 30 percent in cost and saves drivers two to five percent in fuel consumption, tire wear, and vehicle repairs. Keeping roads in good shape also cuts greenhouse gases by as much as two percent.
The average American eats three or four eggs a week, and that’s enough to raise your risk for heart attack and death by six to eight percent. Cholesterol is the reason according to a large new study in the Journal of the American Medical Association. It shows that each additional 300 milligrams of cholesterol in your daily diet raises the risk of both heart disease and premature death by about 17 percent. One large egg has about 185 milligrams of cholesterol. However, since eggs have lots of other nutrients, researchers say not to cut them out of the diet, just eat them in moderation.
Common heartburn medications are being linked to kidney failure and chronic kidney disease. The medications are called proton pump inhibitors and are sold under brand names like Prevacid, Prilosec, and Protonix. A study in the journal Pharmacotherapy finds that PPIs increase the risk of chronic kidney disease by as much as 20 percent and quadruple the risk of kidney failure. People over 65 are at highest risk.
And finally, a large new study shows that your Apple watch might be able to detect an irregular heartbeat. The study presented to the American College of Cardiology shows that the watch can flag apparently healthy people who may have atrial fibrillation. Doctors say about a third of the people the watch indicated were in danger actually did have AFib when they later received EKG monitoring. Researchers admit using the watch of an AFib diagnosis is far from perfect.
About a third of people with major depression aren’t helped by the usual treatments. But they have some hope now that the FDA has approved the first completely new kind of drug for depression in years. The drug is a nasal spray called esketamine and it works in hours rather than weeks. Psychiatrists say it’s a major advance, but it’ll have to be used with caution. The drug is derived from an old anesthetic that was known as the party drug “special k,” and comes with a black box safety warning.
Having a teenage child can be frustrating, but scientists think they’ve discovered the one parental skill that can help navigate conflict with teens. It’s the ability to regulate anger. A study in the journal Development and Psychopathology finds that parents who can’t diminish anger are more likely to resort to the use of harsh, punitive discipline, creating hostile conflict. Researchers say dads are worse than moms at regulating anger and are more likely to conclude their teen is intentionally being difficult. So they dish out harsher punishment.
And finally, fast food now accounts for 11 percent of the energy intake in the United States and a new study shows, to no one’s surprise, that fast food meals are getting bigger and saltier. The study in the Journal of the Academy of Nutrition and Dietetics finds that the average fast food entrée has grown by 100 calories since 1986, and the average fast food dessert by 200 calories. On any given day, more than a third of American adults eat fast food.
Scientists are discovering that our food preferences are much more than a matter of taste, and that taste itself is more complicated than we thought. Psychology also plays a role. An expert discusses what determines preferences, such as why some people like jalapeno peppers & black coffee, and some don’t.

Folate, or vitamin b-9, is an essential nutrient, especially for pregnant women. Folic acid is often added to bread, flour, cereal, and pasta to help eliminate deficiencies. Now new research shows supplementation is more important than we thought, because once somebody is short on folate, the damage can’t be fixed. The study in the journal PNAS shows that folate deficiency triggers errors in chromosomes that are passed on as the cell divides. Once those changes occur, they’re permanent.
If you’ve ever fibbed to your doctor, you’re not alone. In fact, a study in the journal JAMA Network Open finds that between 60 and 80 percent of people are less than forthcoming to their doctors about things that could affect their health. People apparently want to avoid being judged or lectured by doctors… or sometimes, they’re simply too embarrassed to tell the truth.
Various forms of dementia are increasing… and now scientists have found that a single specific mutation in one gene can cause one of them. “Frontotemporal dementia” accounts for about 20 percent of all early-onset forms of the disease…. which can affect people as young as their 40’s. A study in the journal Translational Psychiatry has tracked down a single mutation as the cause… and researchers say the finding could be important for both treatment and in research on Alzheimer’s disease.
And finally… a new study shows that forcing kids to apologize usually backfires. The study in the journal Merrill-Palmer Quarterly finds that children who receive an insincere apology dislike the apologizing kid even more than they did before. Transgressors feel worse, too… and don’t learn to have empathy for their victim.
During the holidays, leftovers from gatherings and parties may threaten to take over the refrigerator. An expert discusses consumer-friendly how-to’s, including how to read labels, that can lengthen food life and help avoid food waste.

Acute myeloid leukemia, or AML is one of the deadliest cancers, with a five-year survival rate of about 25 percent… and even when a patient has a lasting remission, the disease almost always relapses. But a new study in the journal Nature Communications finds that the disease appears to be the fault of a single gene, which they’ve located. Researchers say the gene rewires the body’s entire set of blood-forming cells and tissues. They hope the breakthrough could eventually lead to a gene-targeted therapy and improve survival rates.
Scientists have discovered some of the reasons why people with obesity have a higher risk of asthma. A study in the Journal of Physiology—Lung Cellular and Molecular Physiology shows that inflammation in airways is greater in people with obesity. Those with obesity are also more likely to over-respond to allergens in airway muscles…causing the airways to narrow. Researchers say the discoveries may improve asthma treatment.
Teachers often contribute to a diagnosis of attention deficit-hyperactivity disorder in children… but a new study concludes they may be mistaking immaturity for ADHD. The study in the Journal of Child Psychology and Psychiatry shows that it’s most often the youngest kids in a classroom who are diagnosed with ADHD. Experts also say that in children who are diagnosed… it appears that some parts of the brain mature up to three years later than in kids who are not labeled.
And finally… one good way to get the vitamins you need in the future may be to chew some gum. A study in the Journal of Functional Foods shows that gum loaded with vitamins delivers enough of them to significantly raise levels in the blood. Both water-soluble and fat-soluble vitamins were effectively delivered in gum… and researchers say most people think it’s a pleasant way to get nutrition.
