Clinical diagnosis of Alzheimer's may be delayed

In a study of people with mild cognitive impairment (MCI), those who took the drug donepezil were at reduced risk of progressing to a diagnosis of Alzheimer's disease (AD) during the first year of the trial, but by the end of the 3-year study there was no benefit from the drug. Vitamin E was also tested in the study and was found to have no effect at any time point in the study when compared with placebo.

Rates of cervical cancer could jump fourfold to a million a year by 2050

Deaths from cervical cancer could jump fourfold to a million a year by 2050, mainly in developing countries. This could be prevented by soon-to-be-approved vaccines against the virus that causes most cases of cervical cancer- but there are signs that opposition to the vaccines might lead to many preventable deaths. The trouble is that the human papilloma virus (HPV) is sexually transmitted.
