Continuous proton pump inhibitor treatment decreases upper gastrointestinal bleeding and related death in rural area in Japan.
Proton pump inhibitors (PPI) have been rarely used for prevention of upper gastrointestinal bleeding (UGIB) induced by non-steroidal anti-inflammatory drugs (NSAIDs) and/or aspirin in Japan. The increased incidence of UGIB in the aged society is becoming a serious problem. The aim of this study was to retrospectively evaluate whether PPI can prevent UGIB. ⋯ By widespread use of PPI, UGIB and related death has declined significantly. This survey showed that continuous PPI treatment decreases UGIB and related death in community medicine.

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.
