Fresh stem cell hope for liver patients
Patients waiting for a liver transplant could soon have an alternative option thanks to a discovery by Scottish scientists. A team from Edinburgh University has identified a new type of liver stem cells which have the potential to mature into different cell types and help repair a failing liver. Their findings could pave the way for the use of cell replacements instead of organ transplants for those with liver failure, the scientists said. Liver transplantation is currently the only treatment for acute and chronic liver failure. However, the supply of donor livers is insufficient to meet demand. In the UK 20% of patients waiting for a liver transplant will die from liver failure before a suitable donated organ becomes available.
In future, the newly-discovered stem cells could be given to the patient to kick start the liver's natural processes of regeneration.
Dr James Ross, head of the university's Centre for Regenerative Medicine, said: "Potentially, cell replacement therapies could provide alternative treatments that would avoid difficulties associated with obtaining sufficient donor organ transplantation.
"We have now identified primitive cells with the potential to mature into different cell types within and outwith the liver. "It is possible that these cells lie dormant in the adult liver and may be the source of repair cells that are activated by severe liver injury."
False beliefs affect treatment of prostate cancer
Last Updated: 2006-07-07 16:57:12 -0400 (Reuters Health)
NEW YORK (Reuters Health) - Patients newly diagnosed with localized prostate cancer often don't retain information provided by their physicians about treatment options, risks, and expected outcomes, a new study conducted at the University of Colorado at Denver suggests.
Instead, patients are inclined to base their treatment decisions on fear and uncertainty, false impressions, and anecdotes from acquaintances who have been treated for prostate cancer.
To see what factors affect patients' decision-making process, Dr. Thomas D. Denberg and his associates interviewed 20 men with newly diagnosed prostate cancer receiving care from the Denver Veterans Affairs Medical Center . Ages ranged from 54 to 80 years.
As reported in the journal Cancer, regardless of intellectual knowledge of their own clinical condition, most men desired treatment as soon as possible. The patients had unambiguous opinions about prostate removal, which they seemed to equate with the gold standard, against which their decisions were made.
Eight felt surgery was the best option, because they thought it to be the treatment most likely to remove all traces of the cancer. According to Denberg's group, "compared with surgery, other forms of treatment are less immediate, less visible, and more mysterious and indefinite."
Among those who didn't want to have their prostate removed, some of the reasons were based on the belief that surgery and anesthesia is dangerous and possibly deadly, that their recovery would be prolonged and painful, that exposing the tumor to air can cause its spread, and that surgery causes impotence.
Regardless of which option they chose, none of the patients compared side effects of treatments.
Nineteen of the patients were aware of the experiences of acquaintances, and were far more likely to base their treatment decisions on this information rather than their physicians' advice. Nearly half of the subjects independently sought information about the disease, but found it to be confusing and contradictory.
Denberg's group recommends that doctors explicitly describe common misconceptions and correct them. They also advise that they pay greater attention to patients' fears and anecdotal influences.
