Trump divide among American conservative professors.

There has been an outpouring of research on right-wing populist conservatism since the advent of the Trump presidency and right-wing movements in Europe. Yet, little research has been devoted to divisions among conservatives themselves, especially among conservative academics. Although Trump has maintained remarkable unity within the Republican Party for electoral reasons, he has fostered sharp divisions among conservative intellectuals and academicians. This article compares 102 politically conservative professors who are Trumpists and 80 conservative professors who are anti-Trumpists. All 182 function as public intellectuals who advocate their views in print and digital media. Drawing on recent research in the sociology of intellectuals and particularly Pierre Bourdieu's analytical field perspective, this article proposes a fielding political identities and practices framework to show how these two groups of professors (Trumpists and anti-Trumpists) differ in where they teach, their intellectual orientations, their scholarly productivity, where they network with think tanks, scholarly professional associations, and government agencies, and their stances on key issues surrounding the Trump presidency. The academic Trumpists embrace the right-wing populist wave mobilized by Trump and the conservative academic critics resist this move. This polarization of views between these two groups of conservative professors is enduring and rooted in two distinct social networks that connect positions in the academic field to affiliations with think tanks, government agencies, and professional associations in the field of power that reinforce their respective political identities. This research contributes to political sociology, the sociology of intellectuals, and the sociology of conservative politics in American higher education.

Status of confocal laser endomicroscopy in gastrointestinal disease.

Confocal laser endomicroscopy (CLE) is an advanced imaging technique which combines conventional white light endoscopy (WLE) with an integrated or probe based confocal microscope. This allows microscopic examination of the surface epithelium and in vivo diagnosis during endoscopy. Established CLE applications include the diagnosis of Barrett's oesophagus, gastric intestinal metaplasia, coeliac disease and microscopic colitis. CLE can differentiate hyperplastic from adenomatous polyps in the colon and may obviate the need to biopsy all polyps at endoscopy. CLE is particularly helpful in surveillance endoscopy in inflammatory bowel disease where it has been shown to reduce the number of biopsies required and improve the detection of dysplasia. The future of CLE may be with new contrast agents to allow for molecular tagging and improved endoscopic diagnoses. The aim of this review is to describe the technology and techniques involved in CLE, and discuss the evolving applications in obtaining "virtual biopsy" throughout the GI tract.

Rotational assisted endoscopic retrograde cholangiopancreatography in patients with reconstructive gastrointestinal surgical anatomy.

AIM: To evaluate the success rates of performing therapy utilizing a rotational assisted enteroscopy device in endoscopic retrograde cholangiopancreatography (ERCP) in surgically altered anatomy patients. METHODS: Between June 1, 2009 and November 8, 2012, we performed 42 ERCPs with the use of rotational enteroscopy for patients with altered anatomy (39 with gastric bypass Roux-en-Y, 2 with Billroth II gastrectomy, and 1 with hepaticojejunostomy associated with liver transplant). The indications for ERCP were: choledocholithiasis: 13 of 42 (30.9%), biliary obstruction suggested on imaging: 20 of 42 (47.6%), suspected sphincter of Oddi dysfunction: 4 of 42 (9.5%), abnormal liver enzymes: 1 of 42 (2.4%), ascending cholangitis: 2 of 42 (4.8%), and bile leak: 2 of 42 (4.8%). All procedures were completed with the Olympus SIF-Q180 enteroscope and the Endo-Ease Discovery SB overtube produced by Spirus Medical. RESULTS: Successful visualization of the major ampulla was accomplished in 32 of 42 procedures (76.2%). Cannulation of the bile duct was successful in 26 of 32 procedures reaching the major ampulla (81.3%). Successful therapeutic intervention was completed in 24 of 26 procedures in which the bile duct was cannulated (92.3%). The overall intention to treat success rate was 64.3%. In terms of cannulation success, the intention to treat success rate was 61.5%. Ten out of forty two patients (23.8%) required admission to the hospital after procedure for abdominal pain and nausea, and 3 of those 10 patients (7.1%) had a diagnosis of post-ERCP pancreatitis. The average hospital stay was 3 d. CONCLUSION: It is reasonable to consider an attempt at rotational assisted ERCP prior to a surgical intervention to alleviate biliary complications in patients with altered surgical anatomy.

Endoscopic management of peri-pancreatic collections.

Endotherapy of peripancreatic fluid collections is an increasing utilized procedure in interventional endoscopy. The aim of this paper is to provide a general overview of the topic, highlighting the indications, technique, and important management issues relating to endoscopic management of the various forms of peri-pancreatic fluid collections.
