However, there is no information on which is associated with a more intense IAIR and a higher frequency of surrogate markers for ascending intrauterine infection (i.e., positive AF culture and funisitis) between inflammation restricted to chorio–decidua within extraplacental membranes or inflammation restricted to SCF within CP among preterm gestations with acute placental inflammation. The gene discussed is KITLG; the disease is atrial fibrillation.
