Autologous haematopoietic stem cell transplantation (HSCT) with CD34(+) cell selection has recently been used in the treatment of refractory Crohn's disease, showing good safety and promising efficacy. We investigated the safety and efficacy of HSCT with unselected peripheral blood stem cells (PBSCs) in moderate-severe refractory Crohn's disease. ⋯ Autologous HSCT with unselected PBSC appears to be safe and can induce and maintain remission in previously refractory Crohn's disease patients.

To measure the relative risks of adenocarcinomas of the oesophagus and gastro-oesophageal junction associated with measures of obesity, and their interactions with age, sex, gastro-oesophageal reflux symptoms and smoking. ⋯ Obesity increases the risk of oesophageal adenocarcinoma independently of other factors, particularly among men. From a clinical perspective, these data suggest that patients with obesity and frequent symptoms of gastro-oesophageal reflux are at especially increased risk of adenocarcinoma.
