High-fiber diet may raise risk of diverticulosis

For more than 40 years, scientists and physicians have thought eating a high-fiber diet lowered a person's risk of diverticulosis, a disease of the large intestine in which pouches develop in the colon wall. A new study of more than 2,000 people reveals the opposite may be true.

PERC-led study recognized as one of Canada's top achievements in health research

You could call it paying it forward. A trip to the Emergency Department (ED) is every parent's worst nightmare. But what if the information documented as a result of your child's visit could help a child with similar symptoms a few provinces away? Terry Klassen and his research team of leading pediatric emergency physicians at Pediatric Emergency Research of Canada (PERC) have done just that and the impact of their research is today recognized as one of the Top Canadian Achievements in Health Research in 2011.

Small-group dynamics can alter expression of IQ in some susceptible people

In the classic film "12 Angry Men," Henry Fonda's character sways a jury with his quiet, persistent intelligence. But would he have succeeded if he had allowed himself to fall sway to the social dynamics of that jury?

Alexithymia associated with depression in de novo PD patients

Alexithymia has been found to be strongly associated with depression in both general and clinical populations. Alexithymic and depressive symptoms may be partially overlapping, but not all are correlated with depressive symptoms, thus underlining the relative independence of the two disorders. Parkinson's disease (PD) is a clinical condition often characterized by depression and an altered emotional processing. In medicated PD patients alexithymia has a prevalence of 21% and is related to depression.

Three-parent children may be born in near future in an effort to combat mitochondrial diseases

In the next couple of years the scientific community may witness creation of children with genetic material from three parents. British scientists want to start testing a new IVF technique to try to eradicate incurable genetic diseases such as muscular dystrophy.
