Randomized Controlled Trial Multicenter Study Comparative StudyA novel intravenous iron formulation for treatment of anemia in inflammatory bowel disease: the ferric carboxymaltose (FERINJECT) randomized controlled trial.
Anemia is a common complication of inflammatory bowel diseases (IBD) This multicenter study tested the noninferiority and safety of a new intravenous iron preparation, ferric carboxymaltose (FeCarb), in comparison with oral ferrous sulfate (FeSulf) in reducing iron deficiency anemia (IDA) in IBD. ⋯ FeCarb is effective and safe in IBD-associated anemia. It is noninferior to FeSulf in terms of Hb change over 12 wk, and provides a fast Hb increase and a sufficient refill of iron stores.

Multicenter StudyTechnical performance of colonoscopy: the key role of sedation/analgesia and other quality indicators.
It is essential to identify the factors in clinical practice that influence the technical performance of colonoscopy as a basis for quality improvement programs. ⋯ In usual clinical practice, the use of sedation/analgesia, the colon-cleansing quality, the endoscopist experience, and some features related to the colonscopy setting decisively influence the quality of colonoscopy. These factors indicate the targets of future corrective measures to boost the quality of this examination.

Comparative StudyClinical role of 18F-FDG PET-CT in suspected and potentially operable cholangiocarcinoma: a prospective study compared with conventional imaging.
This study was conducted to evaluate the clinical role of integrated positron emission and computed tomography (PET-CT) in patients with suspected and potentially operable cholangiocarcinoma. ⋯ PET-CT improved the accuracy of preoperative staging in patients with cholangiocarcinoma planning to undergo curative resection. Thus, PET-CT had an important clinical impact on the selection of proper treatment.

Adsorptive depletion of elevated proinflammatory CD14+CD16+DR++ monocytes in patients with inflammatory bowel disease.
In human blood, two monocyte populations exist, CD14(++)CD16(-) classical monocytes and CD14(+)CD16(+) proinflammatory monocytes, which account for about 10% of total monocytes, but can expand to promote inflammatory conditions. CD14(+)CD16(+) monocytes produce large amounts of inflammatory cytokines including TNF-alpha and IL-1. Adacolumn adsorptive carriers adsorb from the blood in the column most of the monocytes/macrophages and granulocytes and this has been associated with clinical efficacy in patients with active inflammatory bowel disease (IBD). This study was to investigate the CD14(+)CD16(+) monocyte profile in patients with IBD and the impact of Adacolumn on this proinflammatory phenotype. ⋯ A significant reduction in peripheral CD14(+)CD16(+) monocytes by GMA should mitigate the inflammatory drive and contribute to the clinical efficacy of this procedure. Reduction of CD14(+)CD16(+) monocytes by corticosteroids was also seen. Hence, corticosteroids should enhance the efficacy of GMA. This is the first report on CD14(+)CD16(+) monocytes being decreased by Adacolumn GMA in patients with IBD.

A significant decline in the American domination of research in gastroenterology with increasing globalization from 1980 to 2005: an analysis of American authorship among 8,251 articles.
To determine whether the relative American contribution to gastroenterology research, as determined by authorship in journals, decreased from 1980 to 2005. ⋯ From 1980 to 2005, American representation in American gastroenterologic journals significantly declined, whereas American representation in European gastroenterologic journals moderately increased. The latter finding, together with increased transnational collaboration and increased international representation in editorial boards, suggests that increasing globalization of information, partly due to computers and the Internet, may be an important etiologic factor. This may result in an improving quality of research performed outside America. Other potential etiologic factors include improving standard of living outside America and increasing clinical volume of academic gastroenterologists in America.
