The study, the largest carried out on the topic to date, showed a strong connection between the development of type 1 diabetes in children and viral infections, specifically in the case of enteroviruses.
Authors Professor Heikki Hyoty and Dr Hanna Honkanen of the University of Tampere, Finland, said: “The present study suggests that enterovirus infections in young children are associated with the appearance of islet autoantibodies with a time lag of about one year.
“This finding supports previous observations from other prospective studies suggesting that enterovirus infections may play a role in the initiation of the beta cell-damaging process.”
As many seek to battle the festive bulge in January, a new study has challenged previous findings that any single aspect of diet or lifestyle can be addressed to reduce the risk of obesity in adults.
Researchers at the University of Exeter found instead many fattening aspects of the environment, lifestyle and behaviour interact with a person’s genes to influence his or her waistline — and the strongest influence is poverty.
The findings contradict some studies, which have concluded concentrating obesity policy on specific aspects such as the consumption of fizzy drinks or fried food could make a meaningful difference to help decrease waistlines, especially in those at high genetic risk of obesity.
Dr Jessica Tyrrell, who led the research, said: “There is no ‘silver bullet’ to reducing obesity risk.
Surgery patients who suffer from migraines are more likely to have a stroke around the time of their operation, a study has suggested.
The risk is higher among patients who suffer migraines “with aura” — warning signs such as seeing flashing lights.
Experts at Harvard Medical School in the US said migraines should be factored in when surgeons are assessing a patient’s risk of stroke.
