Merits and risks of postmenopausal hormone therapy

The study was categorized as a primary prevention trial for coronary heart disease, although the fact that mean age at recruitment was 63 years was not given enough importance at that time. WHI investigators concluded that hormone therapy (HT) was not cardioprotective, and, in fact, its riskbenefit ratio did not favor the use of postmenopausal hormones for prevention of chronic diseases.

Implanting dopamine generators in brain cells improves Parkinson's in monkeys

Implanting dopamine generators (dopaminergics) in brain cells has produced improvement in the symptoms in Parkinson's, according to the results of tests carried out with monkeys by the Navarra University Hospital, led by Dr Mar'a Rosario Luquin Piudo, neurologist at the Hospital and at the other Navarra University-based medical centre, CIMA (the Research Centre for Applied Medicine).
