Is the new Geriatric Nutritional Risk Index a good predictor of muscle dysfunction in institutionalized older patients?
GNRI is a good predictor of muscle dysfunction, particularly in men, and useful in identifying patients suitable for nutritional support and physical activity.
The data obtained imply that exposure to native HCV can have an impact on the relative frequencies of CD4+ and CD8+ T cells by selectively suppressing CD4(+) T lymphocyte proliferation and this may occur in both the presence and the absence of measurable HCV replication in these cells. If the virus exerts a similar effect in vivo, it may contribute to the impairment of virus-specific T cell response by altering cooperation between immune cell subsets.
