Gum Disease Raises Arthritis Risk & Other News of Note

Gum Disease Raises Arthritis Risk (WebMD)

“We’ve known for a while that there is an association between gum disease and rheumatoid arthritis. But our new work suggests periodontal disease is causal,” says study head Jerry A. Molitor, MD, PhD, associate professor in the division of rheumatology and autoimmune disease at the University of Minnesota, Minneapolis.

Compared to people with mild or no periodontitis surrounding two or three teeth, people with moderate to severe gum disease are nearly three times more likely to develop rheumatoid arthritis (RA), the study shows. Among never-smokers with moderate to severe gum disease, the risk is increased ninefold…More

Exposure to Alkaline Substances Can Result in Damaged Teeth (ScienceDaily)

It has long been known that acids can erode tooth enamel but a new Swedish study from the Sahlgrenska Academy at the University of Gothenburg shows that strong alkaline substances can damage teeth too – substances with high pH values can destroy parts of the organic content of the tooth, leaving the enamel more vulnerable.

The study was carried out at the Department of Occupational and Environmental Medicine at the Sahlgrenska Academy and published in the Journal of DentistryMore

Junk Food Turns Rats into Addicts (Science News)

Junk food elicits addictive behavior in rats similar to the behaviors of rats addicted to heroin, a new study finds. Pleasure centers in the brains of rats addicted to high-fat, high-calorie diets became less responsive as the binging wore on, making the rats consume more and more food. The results, presented October 20 at the Society for Neuroscience’s annual meeting, may help explain the changes in the brain that lead people to overeat…More

USF Study Says Atkins-Type Diets May Reduce Stress (Tampa Tribune)

Researcher David Diamond wanted to see how much weight rats would gain on a typical American high-fat, high-sugar diet compared to rats on a low-carb, Atkins-type diet.

But several weeks into the study, it took a turn.

Diamond, a psychology professor at the University of South Florida, found that the rats eating a lot of fat and sugar were not only gaining weight, they were becoming anxious. His fat, stressed-out rats were turning the idea of comfort food on its head.

Diamond, also an associate professor of molecular pharmacology and physiology, presented his research this month at the annual Society for Neuroscience conference in Chicago.

It’s a continuation of his work for the Veterans Administration showing stress and a high-fat diet can damage brain cells.

His latest research indicates, however, that the culprit is not fat, but the combination of fat and sugar…More

Vegetables Can Protect Unborn Child Against Diabetes (PhysOrg)

Expecting mothers who eat vegetables every day seem to have children who are less likely to develop type 1 diabetes, is revealed in a new study from the Sahlgrenska Academy at the University of Gothenburg, Sweden.

The results have been published in the journal Pediatric Diabetes.

“This is the first study to show a link between vegetable intake during pregnancy and the risk of the child subsequently developing type 1 diabetes, but more studies of various kinds will be needed before we can say anything definitive,” says researcher and clinical nutritionist Hilde Brekke from the Sahlgrenska Academy…More

Cell Phone May Reduce Bone Density (US News & World Report)

Wearing a cell phone on your hip may reduce bone density in an area of the pelvis commonly used for bone grafts, a new study suggests.

Turkish researchers used dual X-ray absorptiometry to measure bone density at the upper rims of the pelvis (iliac wings) in 150 men who carried their cell phones on their belts. The men carried their phones for an average of 15 hours a day, and had used cell phones for an average of six years.

Bone density was slightly reduced on the side of the pelvis where the men carried their cell phones, the study found. The difference wasn’t statistically significant and didn’t approach bone level density reductions seen in people with osteoporosis. However, the men were relatively young (average age 32), and further bone weakening may occur, said Dr. Tolga Atay and colleagues at Suleyman Demirel University in Isparta.

The study, published in the September issue of the Journal of Craniofacial Surgery, suggests that electromagnetic fields emitted by cell phones may have a harmful effect on bone density…More

Exercise Helps Brains Bounce Back (Science News)

A toned, buff bod isn’t the only thing a workout is good for. Exercise protects special brain cells in monkeys’ brains and improves motor function, a new study finds. The data, presented at a news briefing October 18 in Chicago at the Society for Neuroscience’s annual meeting, adds to a growing body of evidence that shows exercise is good for the brain, too.

“This is sort of a quiet revolution that’s been occurring in neuroscience,” says Carl Cotman, a brain aging expert at the University of California, Irvine, “to realize that physical activity at a certain level impacts the brain in a really profound way”…More

  1. The news relating to periodontal disease being a contributing factors for RA is important because it indicates the need for those who have family members with the disease to take extra special care in looking after their oral health. In this way, it sounds as if a person can take preventative action to minimize their risks of developing the disease.
