Diabetic patients who take rosiglitazone are 60 per cent less likely to develop diabetic retinopathy, say US researchers. They compared medical records of 124 patients treated with rosiglitazone for three years with 158 diabetics not on the drug. They propose that rosiglitazone may preserve vision by reducing the formation of new blood vessels (Arch Ophthalmol 2008; 126: 793-9).
Bottling it up
People who do not talk about traumatic experiences can fare better than those who let it all out, according to US research. The study looked at 3,000 people who took different approaches to dealing with the aftermath of the 9/11 attacks. Those who were unwilling to talk were less likely to be adversely affected years later (J Consulting and Clin Psych Online 2008).
