Nutritional route affects ERK phosphorylation and cytokine production in hepatic mononuclear cells.
Article in Annals of surgery, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectiveTo clarify the influence of nutritional route on hepatic immunity in a murine model. SUMMARY BACKGROUND DATA: Parenteral nutrition is disadvantageous for preventing infectious complications in critically ill and/or severely injured patients as compared with enteral nutrition. To date, lack of enteral nutrition has been demonstrated to impair mucosal immunity, gut barrier function, and the peritoneal defense system. However, influences of nutritional route on hepatic immunity, another important defense system against infection, have not been well studied.
methodsMale ICR mice were randomized to 3 groups: ad libitum chow (chow), intravenous (IV)-TPN and intragastric (IG)-TPN groups. The TPN groups were given isocaloric and isonitrogenous TPN solutions. After the mice had been fed for 5 days, hepatic mononuclear cells (MNCs) were isolated. Hepatic MNC numbers and functions (cytokine production, intracellular signaling, and LPS receptor expression) were determined. Moreover, 1.0 x 10 Pseudomonas aeruginosa were delivered by intraportal injection. Survival and histology were examined.
resultsHepatic MNC numbers were significantly lower in the IV-TPN group than in the chow and IG-TPN groups, without subpopulation changes. As compared with enterally fed mice, cytokine production (TNF-alpha, IFN-gamma, and IL-10) by hepatic MNCs in response to LPS was impaired in parenterally fed mice in association with blunted phosphorylation of ERK1/2, a MAPK. Hepatic MNCs from IV-TPN mice showed decreased expressions of CD14 and TLR4/MD2, as compared with enterally fed mice. Survival times were reduced in the IV-TPN group as compared with the chow and IG-TPN groups.
conclusionPreservation of hepatic immunity with enteral feeding is important for prevention of infectious complications in severely injured and/or critically ill patients.
