Terapia de hormonas por 10 anos em vez de 5 (estudo Cancro Mama)
Um estudo vantajoso para... As farmacêuticas e não só?
http://www.theguardian.com/society/2016/jun/05/breast-cancer-drugs-decade-study-aromatase-inhibitors
Citando:
"Women should be offered 10 years of drugs to prevent the return of breast cancer, rather than five as now, according to a major study showed longer-term treatment reduced the numbers whose disease came back.
Huge numbers of women in the UK and around the world are already taking hormone therapy – drugs that block oestrogen in the body that can fuel breast cancer growth. Many abandon them within the first few years because of the side-effects or because they feel well and do not want to be on medication."

Recuperação de mobilidade com células estaminais depois de AVC (até 3 anos depois)
A fonte da notícia é chinesa mas já a vi noutros lados (e o pequeno estudo é de Stanford):
http://news.xinhuanet.com/english/2016-06/06/c_135414635.htm
Citando: "In an "unprecedented" clinical trial, U.S. researchers have successfully reversed the long-term debilitating effects in some of the stroke patients by injecting stem cells directly into their brains.
"This wasn't just, 'They couldn't move their thumb, and now they can,'" lead author Gary Steinberg, professor and chair of neurosurgery at the Stanford University School of Medicine, said in a statement.
"Patients who were in wheelchairs are walking now," said Steinberg, who led the 18-patient trial and conducted 12 of the procedures himself."
(...)
"The stem cells, called SB623, are derived from the bone marrow of adult donors and modified to beneficially alter the cells' ability to restore neurologic function."
