Following resection, the decision to restore bowel continuity must incorporate patient factors, intraoperative factors, and surgeon preference
DIVERTICULITIS. WHEN URGENT SIGMOID COLECTOMY?
Urgent sigmoid colectomy is required for patients with diffuse peritonitis or for those in whom non-operative management of acute diverticulitis fails

Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Acute severe colitis: emergent or urgent operation and surgical options.
More extensive and definitive procedures for ASC (IPAA) are technically feasible but proctectomy is rarely required for symptomatic relief at the moment of an emergent surgery. Furthermore these patients are in most cases nutritionally depleted and on high-dose steroids which increases the risk for an anastomotic complication
Variations on the Author
“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Crohn's Disease and post-operative recurrence: analysis of potential risk factors.
The high incidence of postoperative recurrence in Crohn's disease mandates a strict follow up (clinical, laboratory and instrumental monitoring). Identifying patients with increased risk would enable physicians to plan a surveillance program and to implement a rational therapeutic prophylaxis
Appropriate Similarity Measures for Author Cocitation Analysis
We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
