The cost impact of outreach testing and treatment for hepatitis C in an urban Drug Treatment Unit.

Background & Aims: In developed countries persons who inject drugs (PWID) represents a significant risk for chronic hepatitis C virus (HCV). It is reported that up to half of persons with chronic HCV remain undiagnosed and reliance on attendance to specialist clinics remain a barrier to treatment. This study assesses the feasibility and cost-effectiveness of outreach screening and treatment within a Drug Treatment Unit (DTU).

Age-related retinal degeneration in animal models of aging: possible involvement of taurine deficiency and oxidative stress.

There is strong evidence that the retina degenerates with age. Electroretinogram deficits and photoreceptor cell death and structural abnormalities have been observed in both animal and human studies of aging. The mechanism behind this phenomenon is a very interesting area for scientific and medical study.
