To test the hypothesis that non-diabetic dizygotic and monozygotic twin siblings of patients with type 1 diabetes have a similar high prevalence of islet cell autoantibodies, thus suggesting that islet cell autoimmunity is mainly environmentally determined. ⋯ Monozygotic and dizygotic twins differ in progression to diabetes and expression of islet cell autoantibodies. Dizygotic twin siblings are similar to non-twin siblings. These two observations suggest that genetic factors play an important part in determination of islet cell autoimmunity, thus rejecting the hypothesis. In addition, there is a high penetrance of islet cell autoimmunity in DQ8/DQ2 monozygotic twin siblings.

Comment Randomized Controlled Trial Multicenter Study Clinical Trial
Efficacy and safety of rivastigmine in patients with Alzheimer's disease: international randomised controlled trial.
To assess the effects of rivastigmine on the core domains of Alzheimer's disease. ⋯ Rivastigmine is well tolerated and effective. It improves cognition, participation in activities of daily living, and global evaluation ratings in patients with mild to moderately severe Alzheimer's disease. This is the first treatment to show compelling evidence of efficacy in a predominantly European population.
