Given a passage, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

In mice, the farnesoid X receptor is involved in bacterial translocation, which can result in spontaneous bacterial peritonitis in patients with cirrhosis. We investigated if polymorphisms in the farnesoid X receptor gene influence the risk for spontaneous bacterial peritonitis.', 'Laboratory and clinical data of 293 cirrhotic patients with ascites and 226 healthy controls were prospectively collected. The rs56163822, rs11110390 and rs12313471 polymorphisms of the farnesoid X receptor were determined.', '115 (39%) patients had spontaneous bacterial peritonitis. Distribution of all farnesoid X receptor genotypes matched the Hardy-Weinberg equilibrium. Patients with spontaneous bacterial peritonitis had a higher frequency of the rs56163822 GT genotype (7.0%) than patients without (1.7%, OR=4.4, p=0.02). This genotype was confirmed as predictor of spontaneous bacterial peritonitis by binary logistic regression analysis (OR=6.8, p=0.018).
Does a farnesoid X receptor polymorphism predispose to spontaneous bacterial peritonitis?

We investigated the function of major superoxide-generating enzymes after remote ischemic preconditioning (IPC) and hepatic ischemia-reperfusion (IR), with the specific aim of assessing the importance of the most relevant NADPH oxidase (NOX) isoforms, NOX2 and NOX4, in the mechanism of action.', '60-min partial liver ischemia was induced in Sprague-Dawley rats in the presence or absence of remote IPC (2 × 10-min limb IR), and hepatic microcirculatory variables were determined through intravital video microscopy and lightguide spectrophotometry during reperfusion. Inflammatory enzyme activities (myeloperoxidase (MPO) and xanthine oxidoreductase (XOR)), cytokine production (TNF-α and HMGB-1), liver necroenzyme levels (AST, ALT and LDH) and NOX2 and NOX4 protein expression changes (Western blot analysis) were assayed biochemically.', 'In this setting, remote IPC significantly decreased the IR-induced hepatic NOX2 expression, but the NOX4 expression remained unchanged. The remote IPC provided significant, but incomplete protection against the leukocyte-endothelial cell interactions and flow deterioration. Hepatocellular damage (AST, ALT and LDH release), cytokine levels, and XOR and MPO activities also diminished.
Does remote ischemic preconditioning differentially affect NADPH oxidase isoforms during hepatic ischemia-reperfusion?

Three-session days were introduced in our endoscopy unit to accommodate the increased demand resulting from the introduction of the National Health Service Bowel Cancer Screening Programme (BCSP). Cecal intubation rate (CIR) and adenoma detection rate (ADR) may decline with time during a standard working day, but data are lacking for an extended three-session day. We assessed colonoscopy performance in an extended three-session day.', 'Colonoscopies performed during the year 2011 were retrospectively analyzed. The CIR and ADR were analyzed according to the time of day when procedures were done: morning (AM), afternoon (PM), or evening (EVE). Because of an expected higher incidence of adenomas in the BCSP patients, ADR was analyzed according to indication (BCSP or non-BCSP).', 'Of the 2574 colonoscopies, 1328 (51.7\u200a%) were in male patients and 1239 (48.3\u200a%) in female patients with a median age of 63 years (interquartile range [IQR], 51\u200a-\u200a70). Of the 2574 colonoscopies, 1091 (42.4\u200a%) were performed in AM lists, 994 (38.6\u200a%) in PM lists, and 489 (19\u200a%) in EVE lists. Time of day did not affect the CIRs for the AM, PM, and EVE lists (90.5\u200a%, 90.1\u200a%, and 89.9\u200a%, respectively; χ (2) [2, N\u200a=\u200a2540]\u200a=\u200a0.15, P\u200a=\u200a0.927). The CIR was reduced in female patients and those with poor bowel preparation (P\u200a<\u200a0.05). After exclusion of the BCSP patients, the ADR was lower in the EVE lists than in the AM and PM lists on univariate analysis, but on multivariate analysis, this difference was not significant (P\u200a>\u200a0.05). The ADR was significantly higher in patients older than 60 years and in men (P\u200a<\u200a0.001). Queue position did not independently influence the CIR or ADR.

Is colonoscopy performance stable during the course of an extended three-session working day?
