Cancer deaths are continuing to decline. In fact, a report from the American Cancer Society trumpets a major milestone—cancer death rates have dropped every year for the last 25 years. Overall, they’ve dropped 27 percent since 1991… but some cancers are even more striking. For example, lung cancer death rates are down by 48 percent among men. Breast cancer death rates are down by 40 percent, and prostate cancer death rates have dropped by 51 percent.

Parents of teenagers are remarkably pessimistic that schools are keeping their kids safe. A study in the Journal of Community Health shows that 36 percent of parents believe their local high school is “highly likely” to have a shooter incident in the next three years. The study finds that the majority of parents are dissatisfied with the systems schools have in place to counteract gun violence.

Two drugs commonly prescribed for type two diabetes may significantly raise the risk for heart attacks. The drugs, sulfonylureas (sul-fon-eye-loor-ee-ahs) and basal insulin, are often prescribed when metformin doesn’t work. But a study in the journal JAMA Network Open shows that patients who take basil insulin are twice as likely to experience cardiovascular harm, and those taking sulfonylureas are 36 percent more likely to be harmed than patients taking newer second-line drugs. Experts say the results should prompt large scale changes in how type two diabetes is treated.

And finally… more than half of people who take medical marijuana for chronic pain admit they’ve driven while under the influence… and one in five users say they’ve driven while they were “very high” in the last six months. The study in the journal Drug and Alcohol Dependence surveyed medical marijuana users in Michigan… where recreational marijuana is also legal. Researchers say they’re troubled that users don’t think there’s much risk to driving under the influence of pot… but they admit they’re not sure how marijuana affects driving for people who use it every day.

Death rates for most major health conditions have been in decline, but chronic kidney disease is a big exception, according to a study in the journal JAMA Open. Researchers say that deaths due to chronic kidney disease have increased overall by 58 percent over the last 15 years… and among people under 55, who previously suffered little chronic kidney disease, death rates are sharply up as well. Scientists blame high-sugar, high-salt foods and the increase in health problems such as high blood pressure and type two diabetes… which can trigger kidney disease.

Some people say having a tough childhood makes kids grow up fast. But a new study in the journal Biological Psychiatry finds that it also ages children prematurely. Researchers analyzed DNA of children age eight to 16 who had been exposed to violence, neglect, or emotional abuse… and found that on a cellular level, they were older than similar children living in a more stable environment. Those changes are reflected in the average age of puberty… which is lower among children growing up in a tough environment.

And finally… if you’re a night owl, your health may suffer for it. Previous studies have linked being a night owl to high blood pressure and cardiovascular disease… and now a study in the journal Chronobiology International has added up the effect—night owls may have a 10 percent higher risk of early death. Researchers admit they don’t know why a person’s chronotype has such an effect.
