1 · What the graph read from it

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.

2 · The registry

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

backgroundHuman studies show that fetal membranes have a limited lifespan and undergo telomere-dependent cellular senescence that is augmented by oxidative stress and mediated by p38 mitogen activated protein kinase (MAPK). Further, these studies suggest that fetal membranes are anatomically and physiologically positioned to transmit senescence signals that may initiate parturition at term.

methodsLongitudinal evaluation of feto-maternal tissues from mouse pregnancies was undertaken to determine the molecular progression of senescence during normal pregnancy. On days 10-18 of gestation, C57BL/6 mice were euthanized. Fetal membranes, placenta, and decidua/uterus were collected. Tissues were examined for Telomere length (TL) and the presence of Phosphorylated (P) p38MAPK and p53, p21 and senescence associated β-Galactosidase (SA- β-Gal).

findingsLinear regression modeling of observed telomere length as a function of gestational age revealed that beta (β), the slope of the linear regression was negative and significantly different from zero for each tissue (fetal membranes, β = -0.1901 ± 0.03125, p < 0.0001; placenta β = -0.09000 ± 0.03474, p = 0.0135; decidua/uterus β = -0.1317 ± 0.03264, p = 0.0003). Progressive activation p38MAPK was observed in all tissues from days 10 to day18, with the highest activation observed in fetal membranes. Activation of p53 was progressive in fetal membranes. In contrast, active p53 was constitutive in placenta and decidua/uterus throughout gestation. Detection of p21 indicated that pro-senescent change was higher in all compartments on day 18 as compared to other days. The number of SA-β-Gal positive cells increased in fetal membranes as gestation progressed. However, in placenta and uterus and decidua/uterus SA-β-Gal was seen only in days 15 and 18.

conclusionsTelomere dependent p38 and p53 mediated senescence progressed in mouse fetal membranes as gestation advanced. Although senescence is evident, telomere dependent events were not dominant in placenta or decidua/uterus. Fetal membrane senescence may significantly contribute to mechanisms of parturition at term.
