Q: Given a passage with a context and an answer, 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.
Context: Sepsis is a systemic inflammatory response to a bacterial infection. Inflammation may result in injury to the small bowel and an increase in translocation of bacteria and toxins across the mucosal barrier, which may contribute to the progression of sepsis. Microcirculatory perfusion or cytopathic hypoxia may cause impairment of tissue bioenergetics and injury in sepsis. The objective of this study was to determine if sepsis is associated with microcirculatory hypoperfusion and impaired tissue bioenergetics in the ileal mucosa.', 'Sprague-Dawley rats were randomized to cecal ligation and perforation (sepsis group, n = 12) or control group (n = 14) and received arterial and venous catheters and fluid resuscitation. Following 24 h, rats were anesthetized with isoflurane and the ileum was prepared for intravital microscopy. Images of NADH fluorescence, which is an index of tissue bioenergetics, central arterial diameter, red cell velocity, red cell flux, and average intercapillary area, were recorded in 6-9 villi in each rat.', 'Central arterial red cell flux (control 277 +/- 30 cell/s, sepsis 108 +/- 13 cells/s, p < .05), diameter (control 10.4 +/- 0.4 microm, sepsis 8.2 +/- 0.3 microm, p < .05) and red cell velocity (control 590 +/- 47 microm/s, sepsis 449 +/- 63 microm/s, p < .05) were decreased while average intercapillary area (control 815 +/- 171 microm(2), sepsis 1412 +/- 364 microm(2), p < .05) and NADH fluorescence (control 116 +/- 6 AIU, sepsis 154 +/- 9 AIU, p < .05) were increased at the villus tip in the sepsis group.
Answer: Sepsis is associated with bioenergetic impairment and capillary hypoperfusion at the villus tip and a decrease in red cell flux in the central arteriole.
A:
Are tissue bioenergetics and microvascular perfusion impaired in rat ileal mucosa in normotensive sepsis?
