Reading the medscape review of medicine, eyebrow raisers:

1. ADA says that A1c levels can now be used to diagnose DM
2. Ca supplements without Vit D increases risk of heart attack. Use Ca rich food instead
3. emtricitabine/tenofovir (Truvada) pre-exposure prophylaxis works - 44% lower infection rate in treatment group
4. High consumption of chocolate linked to lower incidence of stroke!
5. low-dose helical CT can be used for screening lung CA with associated lower mortality rate
