  1. 1. Biomarkers in mid-trimester amniotic fluid in relation to gestational duration and spontaneous preterm delivery

    Författare :Maria Hallingström; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; amniotic fluid; biomarkers; cytokine; damage-associated molecular pattern; gestation; gestational duration; inflammation; labor; mid-trimester; multiplex; pregnancy clock; proteins; spontaneous preterm delivery; term delivery;

    Sammanfattning : Background: The biological mechanisms and physiological pathways of pregnancy maintenance and timing of delivery are complex and multifactorial. Pregnancy clocks, partly controlled by timing mechanisms linked to fetal development, which regulate the onset of labor has previously been described. LÄS MER

  3. 2. Pregnancy Ultrasound Detecting Soft Markers – the Challenge of Communicating Risk Figures

    Författare :Annika Åhman; Anna Sarkadi; Christine Rubertsson; Peter Lindgren; Marie Berg; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pregnancy; Ultrasound; Soft markers; Prenatal; Screening; Fathers; Informed decision making; Decision aid.; Obstetrik och gynekologi; Obstetrics and Gynaecology;

    Sammanfattning : This thesis focuses on expectant parents’ experiences and needs when soft makers are detected at mid-trimester ultrasound, resulting in an unexpected assessment of risk for fetal anomalies. The thesis also describes the prevalence of ultrasonographic fetal soft markers and the incidence of Down syndrome in a low-risk population of 10,535 pregnant women with a total of 10,710 fetuses, as well as the risk of invasive prenatal diagnostics in conjunction with the detection of soft markers.

  4. 3. Estimation of gestational age by ultrasound and extreme prematurity

    Författare :Marija Simic; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :pregnancy;

    Sammanfattning : Accurate estimation of the gestational age of the fetus is a key assessment made by providers of obstetric care during pregnancy, since decisions concerning management strategies are dependent on this estimate. Thus, the prognosis for preterm infants born at the border of viability is strongly dependent on the accuracy with which gestational age can be determined. LÄS MER

  5. 4. Endothelin and endothelin receptors in human pregnancy and delivery

    Författare :Kerstin Wolff; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Endothelin; endothelin receptor; human; pregnancy; preeclampsia; delivery;

    Sammanfattning : Background: Endothelin-1 (ET-1) is a 21-amino acid peptide, first described by Yanagisawa et al in 1988. It is one of the most potent constrictors of smooth muscle cells identified to date. LÄS MER
