LPS-induced maternal inflammation promotes fetal leukocyte recruitment and prenatal organ infiltration in mice.

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
backgroundA pro-inflammatory intrauterine milieu accounts for increased perinatal morbidity and mortality. We asked how maternal inflammation as seen in endotoxemia affects fetal leukocyte recruitment in vivo during late gestation.
methodsInflammation was induced in pregnant LysEGFP-mice by intraperitoneal LPS injection between gestational day 14 and 18 (E14-E18). After 20 h, intravital fluorescence microscopy was performed on fetal yolk sac venules to examine leukocyte rolling (number of rolling cells/min) and adhesion (>30 s). Infiltration of neutrophils into chorion/amnion, lung, and kidney were quantified by immunofluorescence microscopy.
resultsAt high doses (2 × 1 mg/kg), LPS triggered preterm birth (PTB) and intrauterine fetal death (IUFD), with early gestations at high risk of IUFD and late gestations prone to PTB. Lower LPS dosing (2 × 0.25 mg/kg) did not induce labor, but promoted maternal and fetal cytokine production, as well as neutrophilic infiltration of fetal membranes, as seen in chorioamnionitis (CAM). Baseline fetal leukocyte recruitment increased throughout gestation, and maternal inflammation further augmented adhesion at E16-E18. Enhanced leukocyte recruitment ultimately translated into prominent infiltration of fetal lung and kidney.
conclusionLPS-induced maternal endotoxemia promotes IUFD, PTB, and fetal leukocyte recruitment depending on gestational age. Our proposed model may serve as a platform to test novel perinatal immune modulators.
