1 in 4 US HIV patients don't stay in care, Penn study shows
Only about 75 percent of HIV/AIDS patients in the United States remain in care consistently, according to new research from the Perelman School of Medicine at the University of Pennsylvania published online this week in AIDS. The study of patients across the United States is the first to provide a comprehensive national estimate of HIV care retention and information about patients who are most likely to continue their treatment over time.

Effectiveness of Chinese herbal medicine in treating liver fibrosis: a systematic review and meta-analysis of randomized controlled trials
The studies on the effectiveness of Chinese herbal medicines (CHM) in treating liver fibrosis (LF) were not consistent. This study aims to systematically review the effectiveness of CHM on treating LF patients. The current inconclusive results in determining the effectiveness of CHM treatment on LF, due to the poor methodological quality and high heterogeneity of the studies, suggests that large RCTs using standardized Chinese medicine syndrome diagnosis and CHM formulae with longer follow-up are required for further evaluation.

From mouse to man > Circadian nitrogen balance impacts survival and susceptibility to common diseases
Researchers at Case Western Reserve University School of Medicine demonstrated that nitrogen balance, the process of utilizing amino acids and disposing of their toxic byproducts, occurs with a precise 24-hour rhythm -- also known as circadian rhythm -- in mammals. Disruption of this cycle has a direct impact on survival of organisms, and may predispose one to life altering diseases including diabetes and cardiovascular disease.
