Rodent Model of Cardiopulmonary Bypass Demonstrates Systemic Inflammation and Neuromarker Changes.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionThe physiologic derangements imposed by cardiopulmonary bypass (CPB) can result in complications such as postoperative delirium. We aim to validate a rodent survival model of CPB demonstrating a systemic inflammatory response and hypothesize that this contributes to post-CPB delirium.
methodsAdult Sprague-Dawley rats were randomized to three groups: 1) Sham peripheral surgical cannulation, 2) CPB followed by acute phase harvest, or 3) CPB followed by 24-h survival. CPB was carried out for 60 min before decannulation and weaning from mechanical ventilation. Physiological and biochemical endpoints were compared between groups. Gene expression analysis of hippocampal tissue was performed using quantitative RT-PCR panels and protein expression levels were confirmed with Western blot.
resultsSixteen animals underwent cannulation and were successfully decannulated without transfusion requirement or inotrope use with one procedure-related mortality. Serum acute phase proinflammatory chemokines cytokine-induced neutrophil chemoattractant 1, cytokine-induced neutrophil chemoattractant 3, fractalkine, and lipopolysaccharide-induced CXC chemokine as well as interleukin (IL)-10 were increased 1 h following CPB compared to sham (P < 0.05). Significant changes in hippocampal expression of biomarkers apolipoprotein 1, vascular epithelial growth factor A, and synapsin 1 were demonstrated following CPB.
conclusionsThis study validated a model of CPB that captures the resultant systemic inflammatory response, and identified differentially expressed proteins that may be associated with brain injury. Modulation of the CPB-induced inflammatory response may be a promising therapeutic target to attenuate post-CPB delirium, and this survival rat model of CPB with low surgical attrition will allow for more comprehensive evaluations of the short- and long-term effects of both CPB and potential therapeutic interventions.
