Peroxisome proliferator-activated receptor-α agonist, Wy 14,643, improves metabolic indices, steatosis and ballooning in diabetic mice with non-alcoholic steatohepatitis.
Lipid accumulation precedes hepatocellular injury and liver inflammation in non-alcoholic steatohepatitis (NASH). The peroxisome proliferator-activated receptor (PPAR)α regulates hepatic lipid disposal. We studied whether pharmacological stimulation of PPARα reverses NASH associated with metabolic syndrome in high-fat (HF)-fed foz/foz obese/diabetic mice. ⋯ Pharmacological activation of PPARα improves metabolic milieu, steatosis, ballooning, and combats NF-κB and JNK activation, neutrophil and F4/80 macrophage recruitment in diabetes-related NASH. However, persistent liver inflammation with high serum MCP1 due to unsuppressed adipose inflammation may limit PPARα agonists' efficacy as therapy for NASH.

Multicenter StudyHealth utilities and psychometric quality of life in patients with early- and late-stage hepatitis C virus infection.
Hepatitis C virus (HCV) infection is associated with impairment in health-related quality of life (HRQOL). The purpose of this study was to evaluate HRQOL across the HCV disease spectrum using preference-based (utility) and non-preference-based (psychometric) methods, adjusting for sociodemographic factors and co-morbidity. ⋯ The effect of stage of disease on HRQOL is modest, although viral clearance is associated with higher HRQOL. HCV patients' HRQOL is strongly associated with concomitant illness and sociodemographic factors.

Factors that influence cecal intubation rate during colonoscopy in deeply sedated patients.
The technical performance of colonoscopy performed in deeply sedated patients differs from that performed without sedation or under minimal to moderate sedation. The aim of this study is to evaluate the factors affecting cecal intubation during colonoscopy performed under deep sedation. ⋯ Colonoscopy performed under deep sedation by experienced colonoscopists results in high cecal intubation rates. Among the significant patient-related predictors influencing the cecal intubation, the quality of the bowel preparation was the only modifiable factor. When performed by experienced hands, the one-person method was associated with higher cecal intubation rates than the two-person method.
