CD is associated with a microbial signature distinct from health. Microbial factors and smoking independently influence postoperative CD recurrence. The genus Proteus may play a role in the development of CD.

SUMMARY BackgroundCrohn's disease recurs in the majority of patients after intestinal resection.

Peer support appeared to reduce psychologic morbidity and increase social support. The evidence for peer support in critically ill populations is limited. There is a need for well-designed and rigorously reported research into this complex intervention.

Intestinal resection of all macroscopic Crohn's disease in patients treated with postoperative prophylactic drug therapy is associated with significant and sustained improvement in HRQoL irrespective of type of drug treatment or endoscopic recurrence. HRQoL is lower in female patients and smokers. A higher CDAI, but not direct measures of active disease or type of drug therapy, is associated with a lower HRQoL.

Background: IL-6 signaling plays a role in immune and skeletal systems. Results: sIL-6R mediated PTH-dependent hematopoietic cell expansions and blocking sIL-6R reduced PTH anabolic actions in mice. Conclusion: sIL-6R is a mediator of PTH hematopoietic actions in marrow and anabolic actions in bone. Significance: Novel orphan sIL-6R functions support PTH actions in bone and bone marrow.
