Abstract

Inflammation is a process by which tissues respond to various insults. It is characterized by upregulation of chemokines, cytokines, and pattern recognition receptors that sense microbes and tissue breakdown products. During pregnancy, the balance of Th1 (cell-mediated immunity) and Th2 (humoral immunity) cytokines is characterized by an initial prevalence of Th2 cytokines, followed by a progressive shift toward Th1 predominance late in gestation, that when is abnormal, may initiate and intensify the cascade of inflammatory cytokine production involved in adverse pregnancy outcomes. Maternal and placental hormones may affect the inflammatory pathway. Hypoxia and the innate immune response are 2 adaptive mechanisms by which organisms respond to perturbation in organ function, playing a major role in spontaneous abortion, intrauterine growth restriction, preeclampsia, and preterm delivery. The interaction between tissue remodeling factors, like matrix metalloproteinases, and vasoactive/hemostatic factors, like prostaglandin and coagulation factors, mediates this adaptive response.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • There is a mild and sustained inflammatory response in pregnancy.

    From Hypoalbuminemia: Pathogenesis and Clinical Significance (2019) · cites this paper as [10]

  • In pregnancy, synthesis of cytokines and growth factors is mildly increased while exhibiting Th1 helper cell dominance, but is further upregulated and changed to Th2 helper cell dominance during fetal distress, and decreases when resulting in premature birth.

  • Increased cytokine expression occurs after trauma or infection and also in physiologic states including pregnancy and other situations where increased cell proliferation and matrix deposition are required.

    “Increased cytokine expression does not only happen after trauma or infection, but also in physiologic states including pregnancy and other situations where increased cell proliferation and matrix deposition are required.8, 9, 10”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
