The findings highlight the need for effective therapeutic interventions for this highly lethal syndrome.
A randomized controlled trial found that women taking vitamin C, E, or beta carotene had a similar risk of cancer as those not taking the supplements. Antioxidant supplements were previously thought to lower cancer risk due to high fruit and vegetable intake, but this study contradicts those findings.

The study found that this approach improved clinical outcomes without increasing adverse events.
Two new studies found that treating Hepatitis C with peginterferon and ribavirin for shorter durations can yield similar success rates to longer treatments, with cost savings and reduced risk of serious side effects. Patients' HCV-RNA levels after 4 weeks may be an important factor in determining the best treatment length.
