  ABSTRACT: The aim of this study was to evaluate the effects of Roux-en-Y gastric bypass for morbid obesity on health-related quality of life (QOL) during the first year of follow-up. The World Health Organization Quality of Life-Brief (WHOQOL-BREF) was administered 1 month before operation, and at 1, 3, 6 and 12 months after surgery. Body mass index, co-morbidities and operation-related complications were measured at these times. A mixed-effect model was constructed to analyse repeated measurements and determine the relationships between body mass index, WHOQOL-BREF scores and other variables. A total of 102 patients were enrolled. The mixed-effect model showed that the physical, psychological and social domains improved after bariatric surgery, with simultaneous reduction in weight and improvement in co-morbidities. There was a dip in scores in physical and psychological domains 3-6 months after surgery, significantly related to complications. All patients gradually improved between 6 and 12 months after surgery, reaching levels similar to those of healthy subjects. Health-related QOL improved dramatically after bariatric surgery, dipped slightly between 3 and 6 months, and improved again up to the end of the first year.

  ABSTRACT: Although narrow-band imaging (NBI) in endoscopy can improve detection of early-stage esophageal malignancies in patients with head and neck cancers, false-positive results may be obtained in areas with nonspecific inflammatory changes. This study evaluated the feasibility of primary screening with NBI and magnification for the presence of esophageal malignancies in these cancer patients. Sixty-nine patients with documented head and neck cancers were enrolled from April 2008 to January 2009. All patients underwent a meticulous endoscopic examination of the esophagus using a conventional white-light system followed by re-examination using the NBI system and final confirmation with NBI plus magnification. Twenty-one patients (30.4 %) were confirmed to have esophageal neoplasia. Among these 21, 16 (76.2 %) had synchronous lesions, 9 (42.9 %) were asymptomatic, and 10 (47.6 %) had early-stage neoplasia. The incidence of multiple esophageal neoplasia was 57.1 %. NBI was more effective than conventional endoscopy in detecting neoplastic lesions (35 lesions in 21 patients vs. 22 lesions in 18 patients) and was particularly effective in patients with dysplasia (13 lesions in 9 patients vs. 3 lesions in 3 patients). The sensitivity and accuracy of detection were 62.9 % and 64.4 % for conventional endoscopy, 100 % and 86.7 % for NBI alone, and 100 % and 95.6 % for NBI with high magnification, respectively. Compared with current approaches, NBI followed by high magnification significantly increases the accuracy of detection of esophageal neoplasia in patients with head and neck cancers. The result warrants conducting prospective randomized controlled study to confirm its efficacy.
