Bubbly drink trial 'to boost cancer therapy' - BBC News
Bubbly drink trial 'to boost cancer therapy' - BBC News
Citando:
"One reason thought to behind this is that cancers grow rapidly and their blood supply fails to keep up - leaving tumours with torturous, poorly-formed blood vessels that don't deliver oxygen-rich blood as well.
Prof Eleanor Stride, from Oxford University, says the lack of oxygen makes cancer cells "go into survival mode" making them more hardy and therefore less responsive to radiotherapy and drugs.
This is a particular problem for hard-to-treat cancers such as tumours of the pancreas, she says.
The team has already found that injecting oxygen in mice with cancer and then giving them chemotherapy leads to more successful treatments.
They recently carried out a small-scale trial of an oxygen-rich drink in mice.
The next stage is to repeat the mice experiments in much larger numbers, before human trials are considered.
But Prof Stride says: "I wouldn't suggest people rush out to buy any drinks claiming to be rich in oxygen."

Should You Get Tested for the Breast Cancer Genes? - Scientific American
Should You Get Tested for the Breast Cancer Genes? - Scientific American
Citando:
"The mostly common involved and most familiar breast cancer genes are the BRCA-1 and BRCA-2 genes. This sort of gene testing can be performed on blood, saliva, or even cheek swabbing. The challenge? Hundreds of genes involving these two mutations have been discovered. Therefore, obtaining a complete test for all involved possibilities can cost up to 4,000 dollars. If patients meet certain criteria, however, insurance may cover up to 90% of the testing cost. What may be less costly and more simple, however, is if you already have an identified gene in another relative, in which testing can be more targeted and therefore much less costly."

""The medical profession can't even define the exact definition of health, but I'm encouraging people please don't do what my father did and die of ignorance," he said.
"We don't understand energy, that's why we have quantum physics and a bunch of people in CERN (the European Organization for Nuclear Research) trying to understand it.
"I could have gone down the same route. I believe pulsed electromagnetism has a role to play in tackling cancer and I will always believe that.""
(...)
"In a follow up statement, the company said: "Although research using very low frequency and intensity PEMF ([pulsed electromagnetic field) to help address cancer has produced some promising early results, it is currently in the very early stages and EMPpad does not make the claim that PEMF therapy can prevent cancer."

Anti-depressivos ineficazes em jovens - Estudo
Sabiam desta?
"(...)only a limited amount of research has been done on antidepressant use in children and teens."
Dados os efeitos secundários é surpreendente que sejam tão receitados a jovens.
http://www.cbsnews.com/news/most-antidepressants-ineffective-in-teens-study/
Citando:
"The findings show that out of 14 antidepressants, only fluoxetine (sold under brand names Prozac and Sarafem) was more effective at relieving symptoms of depression in young people than a placebo pill. In contrast, taking venlafaxine (Effexor) was associated with an increased risk of suicidal thoughts and suicide attempts when compared to a placebo and five other antidepressants."

Dúvidas nas recomendações para prolongar tratamento cancro da mama
http://www.m.webmd.com/a-to-z-guides/news/20160606/longer-use-of-certain-drugs-cuts-recurrence-for-breast-cancer-survivors (relacionado com este artigo anterior)
Citando:
"Many survivors of breast cancers that are sensitive to estrogen are advised to take hormone-suppressing drugs such as tamoxifen for five years, to cut their odds for a recurrence.
Tamoxifen can have onerous side effects, however. Now, new research finds that taking an alternative, and less troublesome, class of medications for a full decade can reduce the risk for recurrence even more -- without affecting a woman's quality of life.
The newer class of hormone-suppressing drugs are called aromatase inhibitors, and include drugs such as letrozole (Femara), anastrozole (Arimidex) and exemestane (Aromasin)."
