We’ve reported on how dogs can sniff out a variety of diseases in people with scientists trying to create a mechanical nose to do the same thing. Now a study presented to the American Chemical Society shows they’re making progress. Researchers have identified a signature odor in 90% of cases of prostate cancer and have developed a chemical test to detect it. Doctors are looking for an alternative to the PSA test to detect prostate cancer because of the high proportion of false positives.
People who are depressed have a surprisingly high risk for heart disease. A new study in the journal Atherosclerosis shows that depression is just as much of a cardiovascular risk as obesity and high cholesterol. The 10-year study finds that depression is to blame for about 15% of all heart disease deaths, a rate exceeded only by smoking and high blood pressure. About 350 million people around the world suffer from depression.
It might be easier to get into an argument when you’re tired because you’re misreading the emotions of other people. A study in the journal Neurobiology of Sleep and Circadian Rhythms shows that sleepy people have trouble interpreting some emotions in the faces of others compared to those who are well rested. Tired people can read fear and anger in others’ faces but more subtle emotions are misinterpreted far more often.
And finally, slightly more than half of parents give sports the green light for their kids but about one in every six completely rule them out. The reason? Concussions. The rest of parents, about a third of them, allow participation on a sport by sport basis, according to a Harris survey for the American Osteopathic Association. About two thirds of parents say basketball and baseball are ok for kids. But less than 20% approve of their children playing football.
People who’ve gone to the hospital for treatment of a mental health disorder have an increased risk of stroke for months afterward. A study presented to the International Stroke Conference in Houston shows that people going to the hospital for psychiatric disorders like depression, anxiety and PTSD have triple the risk of a stroke in the next month and double the risk for the next year or more. Scientists speculate that mental illness may provoke the body’s “fight or flight” mechanism which can raise blood pressure and stroke risk.
Early risers may be healthier than people who sleep in. A study in the journal Obesity shows that early birds tend to eat more balanced diets than night owls. They also eat earlier in the day, which helps with weight loss and lowers the risk of diabetes and heart disease.
And finally, many Americans are working from home at least part of the time and a new poll shows we like it that way. However, a little bit of office camaraderie is a good thing. The Gallup survey finds that 43 percent of employees work remotely at least part of the time and that the most engaged workers are those who spend three to four days a week working from home. People who work in the office all the time or at home all the time are the least engaged employees.
Doctors have long known that people feel depressed when they’re ill with a cold or the flu. But it may be more than simply feeling bad. Inflammation, which is part of many illnesses and infections, has been found in brain cells and is being implicated as a cause of depression., one of the world’s most debilitating disorders. This creates the possibility of treatment with anti-inflammatory medications. Experts on the frontlines of this research discuss.
Doctors are attempting suicide in high numbers, and are much more likely than the general population to complete it. Experts discuss the coverup of doctor suicides, the reasons behind depression in doctors, and why doctors who are depressed are less likely than normal to get help.
Synopsis: Many people are familiar with the use of Botox to reduce wrinkles and frown lines. But Botox can also be used to reduce the effects of depression. One of the principal researchers on this subject explains.
