Below is a glossary of important terms used in the prediction model for preeclampsia in twins:
-
cffDNA: Cell-free fetal DNA test, which helps assess the risk of preeclampsia and other pregnancy-related complications.
-
MAP (Mean Arterial Pressure): The average blood pressure in an individual during a single cardiac cycle, which is a key indicator of preeclampsia risk.
-
PLGF (Placental Growth Factor): A protein involved in angiogenesis and placental development; low levels of PLGF are associated with preeclampsia.
-
SFLT1 (Soluble fms-like tyrosine kinase 1): A protein that inhibits vascular endothelial growth factor (VEGF) and placental growth factor (PLGF); elevated levels are indicative of preeclampsia.
-
SFLT1/PLGF Ratio: A ratio of the soluble fms-like tyrosine kinase 1 to placental growth factor, which is used as a marker for preeclampsia risk.
-
Blood Type: The patient's blood group, which can affect pregnancy outcomes.
-
Nulliparous: A term used to describe a woman who has never given birth to a viable offspring.
-
Diabetes Mellitus (DM): A chronic condition affecting blood sugar regulation; women with diabetes are at a higher risk for preeclampsia.
-
Gestational Age (GA): The duration of pregnancy, usually measured in weeks from the first day of the last menstrual period.
-
Pregnancy Trimester: Refers to the three stages of pregnancy: the first trimester (0-12 weeks), second trimester (13-26 weeks), and third trimester (27 weeks to delivery).
-
Twins Pregnancy: A pregnancy involving two fetuses, which can increase the likelihood of complications such as preeclampsia.
-
Blood Pressure at Admission: The maternal blood pressure measured upon admission to the healthcare facility, which is a crucial indicator for preeclampsia risk.
-
History of Previous Hospitalizations: The number of hospital admissions the patient has had during the current pregnancy, which can indicate heightened risk.
-
Fetal Weight: The estimated weight of the fetus, which may influence the prediction of preeclampsia in twin pregnancies.
