Background： The aim of this study was to evaluate the impact of jejunostomy during esophagectomy for cancer on postoperative health-related quality of life（HRQL）.Methods： We evaluate all consecutive patients who underwent esophagectomy for cancer at the surgical oncology unit of the Veneto Institute of Oncology（IOV-IRCCS） between January 2008 and March 2014. The primary outcome was HRQL, which was assessed using nine scales of EORTC C30 and OES18 questionnaires. General linear models were estimated to evaluate mean score difference（MD） of each selected scale in patients with and without jejunostomy, adjusting for clinically relevant confounders. The secondary outcomes were morbidity, hospital stay, postoperative weight loss and postoperative albumin impairment. Results： Jejunostomy was performed in 40 on 109 patients（41.3%） who participated in quality of life investigation. A clinically and statistically significantly worse eating at admission（P=0.009） became not clinically significant at 3 months after surgery（MD =9.1）. Jejunostomy was associated to clinically and statistically significantly poorer emotional function（EF） at 3 months after surgery（MD =-15.6; P=0.04）. Hospital stay was longer in jejunostomy group（median, 20 vs. 17 days, P=0.02）.Conclusions： In our series patients who had a jejunostomy during esophagectomy had been selected for their risk for postoperative complication. However, their postoperative outcome was actually similar compared to those without jejunostomy. Nevertheless, jejunostomy was associated to clinically and statistically significantly poorer EF at 3 months after surgery. Therefore, patient candidate to esophagectomy and feeding jejunostomy should receive additional psychological support.

Abnormal subchondral bone remodeling leading to sclerosis is a main feature of osteoarthritis(OA), and osteomodulin(OMD), a proteoglycan involved in extracellular matrix mineralization, is associated with the sclerotic phenotype. However, the functions of OMD remain poorly understood, specifically in vivo. We used Omd knockout and overexpressing male mice and mutant zebrafish to study its roles in bone and cartilage metabolism and in the development of OA. The expression of Omd is deeply correlated with bone and cartilage microarchitectures affecting the bone volume and the onset of subchondral bone sclerosis and spontaneous cartilage lesions. Mechanistically, OMD binds to RANKL and inhibits osteoclastogenesis, thus controlling the balance of bone remodeling. In conclusion, OMD is a key factor in subchondral bone sclerosis associated with OA. It participates in bone and cartilage homeostasis by acting on the regulation of osteoclastogenesis. Targeting OMD may be a promising new and personalized approach for OA.
