To floss or not to floss: That is suddenly the question
For decades, the federal government and dentists have recommended flossing daily to prevent cavities and gum disease.
Now the evidence for flossing appears to be hanging by a string.
The Associated Press announced last week that its investigation of 25 studies on flossing found the data supporting its benefits to be “weak, very unreliable,” while also noting that the federal government’s new dietary guidelines have quietly removed any mention of flossing.
If you’re smiling about the news — a recent study found that nearly one-third of American adults never floss — hold on.
Should you still floss? Yes, say exp...

Latin American, Caribbean health systems need more investment as populations age
The health systems of six Latin American and Caribbean countries have made substantial progress toward universal coverage — providing free or subsidized healthcare to the majority of their populations — but continue to face challenges managing more complex health needs such as those related to cardiovascular disease, cancer, stroke and depression, a new study from the UCLA Fielding School of Public Health and the Inter-American Development Bank finds.
Though the health systems in Brazil, Colombia, El Salvador, Jamaica, Mexico and Panama have considerable strengths, citizens still reported gaps in the way primary care i...

Simply moving 30 minutes a day can lower your health risks
If you spend hours commuting to work and sitting at your desk all day, recent studies about the health hazards of too much sitting probably have hit home.
“Humans are not biologically designed to be sedentary,” says Elisa Terry, program director of the UCLA Recreation Fitwell program. “The more you sit, the unhealthier it is for your body.”
Being sedentary increases risks for diabetes, high blood pressure and poor circulation.

MRI scan may help diagnose chronic traumatic encephalopathy, UCLA researchers report
UCLA doctors have found what may be an earlier and easier way to diagnose chronic traumatic encephalopathy, or CTE, a disorder that is thought to affect some former football players and others with a history of repetitive brain trauma.
Using a new software tool for analyzing MRI scans, the researchers detected the shrinkage of several key brain regions in a former football player with cognitive problems. The same pattern of brain changes is commonly seen in CTE cases that have been confirmed by autopsies after a person’s death.
While the findings from this single case report are preliminary, they raise the possibility th...

Analyzing brain patterns may help neuroscientists increase people ’s confidence, reduce fear
A new technique of analyzing brain patterns appears to help people overcome fear and build self-confidence.The approach, developed by a UCLA-led team of neuroscientists, is described in two new papers, published in the journals Nature Communications and Nature Human Behaviour.Their method could have implications for treating people with depression, dementia and anxiety disorders, including post-traumatic stress disorder, said Hakwan Lau, a UCLA associate professor of psychology and the senior author of both studies. It could also play a role in improving leadership training for executives and managers.In theNature Human Be...

The pain of chronic loneliness can be detrimental to your health
The changes came so gradually that, for a long time, Paula Dutton didn ’t realize she was in trouble. This was just modern life, after all — the cross-country distance from her close-knit family in Philadelphia, the end of a 10-year marriage, the death of one parent and then the other. By the time Dutton retired from her job, she was lonely to a degree that shocked and frightened her.“I just suddenly realized I was all alone and had no one around me and no one I could turn to,” says Dutton, now 71. “I had a lot of pity parties, I can tell you — and with all kinds of anxiety and depression. And I worked myself i...

Head injuries can alter hundreds of genes and lead to serious brain diseases, UCLA biologists report
Head injuries can harm hundreds of genes in the brain in a way that increases people ’s risk for a wide range of neurological and psychiatric disorders, UCLA life scientists report.The researchers identified for the first time master genes that they believe control hundreds of other genes which are linked to Alzheimer ’s disease, Parkinson’s disease, post-traumatic stress disorder, stroke, attention deficit hyperactivity disorder, autism, depression, schizophrenia and other disorders.Knowing what the master genes are could give scientists targets for new pharmaceuticals to treat brain diseases. Eventually, scientists...

Scientists identify brain cells involved in Pavlovian response
In his famous experiment, Russian scientist Ivan Pavlov rang a bell each time he fed his dogs. Soon, the dogs began drooling in anticipation when they heard the bell, even before food appeared.Now, a UCLA study has traced the Pavlovian response to a small cluster of brain cells — the same neurons that go awry during Huntington’s disease, Parkinson’s disease and Tourette’s syndrome. Published March 22 in the journal Neuron, the research could eventually help scientists identify new approaches to diagnosing and treating these neurological disorders.“Species survive because they’ve learned how to link sensory cue...

With a nudge from their wives, three longtime friends get vasectomies in solidarity
Paul Diaz, Basilio Santangelo and John Lambrechts had shared a lot of memorable experiences in their decades of friendship, but going to the doctor to all get vasectomies was one they never expected.The three — each married with two children — had decided with their wives that they didn’t want to continue growing their families. After a pregnancy false alarm, Diaz and his wife, Lisa, agreed that they were happy with their two girls. Lisa brought up the idea of Paul getting a vasectomy, but there wa s a problem.“Like most men,” Diaz said, “I don’t like going to the doctor. I don’t like going to the dentist. ...

High-fat diet leads to same intestinal inflammation as a virus
FINDINGSA new study by scientists at UCLA found that when mice eat a high-fat diet, the cells in their small intestines respond the same way they do to a viral infection, turning up production of certain immune molecules and causing inflammation throughout the body. The scientists also found that feeding the mice tomatoes containing a protein similar to that in HDL, or “good cholesterol,” along with the generic cholesterol drug Ezetimibe, reversed the inflammation.The results could lead to new types of drugs, targeting the intestinal cells, to reduce people ’s risk of heart attacks and strokes, or to treat other cond...
