Teeth Grinding Linked to Sleep Apnea & Other News of Note

Teeth Grinding Linked to Sleep Apnea (Reuters)

There is a high prevalence of nocturnal teeth grinding, or bruxism, in patients with obstructive sleep apnea (OSA), particularly in Caucasians. New research presented at CHEST 2009, the 75th annual international scientific assembly of the American College of Chest Physicians (ACCP), found that nearly 1 in 4 patients with OSA suffers from nighttime teeth grinding; this seems to be especially more prevalent in men and in Caucasians compared with other ethnic groups…More

Junk-Food Binge Alters Gut Microbes in Less Than a Day (Washington University Record)

Switching from a low-fat, plant-based diet to one high in fat and sugar alters the collection of microbes living in the gut in less than a day, with obesity-linked microbes suddenly thriving, according to new School of Medicine research.

The study was based on transplants of human intestinal microbes into germ-free mice.

Over time, mice that received the transplants, or humanized mice, on the junk-food diet became obese. Their weight gain was in lock step with dramatic shifts in the types of intestinal bacteria present compared to mice on a low-fat diet…More

Consumption of Cerain Fish Linked to Poor Cognitive Performance in Kids (DNA)

A new study conducted by researchers at the University of Granada has revealed that kids who eat fish more than 3 times per week show worse performance in the general cognitive, executive and perceptual-manipulative areas.

Those with higher levels of exposure to mercury show a generalised delay in cognitive, memory and verbal areas. Mercury is a contaminant found especially in oily fish and canned fish and to a lesser extent in white fish…More

Emotions Increase or Decrease Pain (PhysOrg)

Getting a flu shot this fall? Canadians scientists have found that focusing on a pretty image could alleviate the sting of that vaccine. According to a new Université de Montréal study, published in the latest edition of the Proceedings of the National Academy of Sciences (PNAS), negative and positive emotions have a direct impact on pain.

“Emotions – or mood – can alter how we react to pain since they’re interlinked,” says lead author Mathieu Roy, who completed the study as a Université de Montréal PhD student and is now a post-doctoral fellow at Columbia University. “Our tests revealed when pain is perceived by our brain and how that pain can be amplified when combined with negative emotions”… More

Brief Training in Meditation May Help Manage Pain, Study Shows (ScienceDaily)

A new study examining the perception of pain and the effects of various mental training techniques has found that relatively short and simple mindfulness meditation training can have a significant positive effect on pain management.

Though pain research during the past decade has shown that extensive meditation training can have a positive effect in reducing a person’s awareness and sensitivity to pain, the effort, time commitment, and financial obligations required has made the treatment not practical for many patients. Now, a new study by researchers at the University of North Carolina at Charlotte shows that a single hour of training spread out over a three day period can produce the same kind of analgesic effect.

The research appears in an article by UNC Charlotte psychologists Fadel Zeidan, Nakia S. Gordon, Junaid Merchant and Paula Goolkasian, in the current issue of The Journal of PainMore
