Altered development of fetal liver perfusion in pregnancies with pregestational diabetes
Lund, Agnethe; Ebbing, Cathrine; Rasmussen, Svein; Kiserud, Torvid; Hanson, Mark; Kessler, Jørg (Peer reviewed; Journal article, 2019-03-13)Background: Pregestational diabetes is associated with fetal macrosomia, and umbilical perfusion of the fetal liver has a role in regulating fetal growth. We therefore hypothesized that pregestational diabetes alters fetal ... -

Diabetes mellitus impact on fetal liver circulation, and new diagnostic options
Kiserud, Torvid (Journal article; Peer reviewed, 2023)While biometry and Doppler have proved useful in the management of fetal growth restriction, the same battery has been of less help in diabetic pregnancies. It is not surprising since the underlying pathophysiology is ... -
Effect of maternal sleep on embryonic development
Vietheer, Alexander; Kiserud, Torvid; Haaland, Øystein Ariansen; Lie, Rolv T.; Kessler, Jørg (Journal article; Peer reviewed, 2022)The concept of developmental origin of health and disease has ignited a search for mechanisms and health factors influencing normal intrauterine development.

Fetal age assessment based on 2nd trimester ultrasound in Africa and the effect of ethnicity
Salpou, Daniel; Kiserud, Torvid; Rasmussen, Svein; Johnsen, Synnøve Lian (Peer reviewed; Journal article, 2008-10-30)Background: The African population is composed of a variety of ethnic groups, which differ considerably from each other. Some studies suggest that ethnic variation may influence dating. The aim of the present study was to ... -
Fetal Liver Blood Flow Distribution: Role in Human Developmental Strategy to Prioritize Fat Deposition versus Brain Development
Godfrey, Keith M.; Haugen, Guttorm; Kiserud, Torvid; Inskip, Hazel M.; Cooper, Cyrus; The Southampton Women's Survey Study Group (Peer reviewed; Journal article, 2012-08-22)Among primates, human neonates have the largest brains but also the highest proportion of body fat. If placental nutrient supply is limited, the fetus faces a dilemma: should resources be allocated to brain growth, or to ... -
Fetal size in the second trimester is associated with the duration of pregnancy, small fetuses having longer pregnancies
Johnsen, Synnøve Lian; Wilsgaard, Tom; Rasmussen, Svein; Hanson, Mark A.; Godfrey, Keith M.; Kiserud, Torvid (Peer reviewed; Journal article, 2008-07-16)Background: Conventionally, the pregnancy duration is accepted to be 280–282 days. Fetuses determined by ultrasound biometry to be small in early pregnancy, have an increased risk of premature birth. We speculate that the ... -
Fetal Superior Vena Cava Blood Flow and Its Fraction of Cardiac Output: A Longitudinal Ultrasound Study in the Second Half of Pregnancy
Stefopoulou, Maria; Johnson, Jonas; Herling, Lotta; Lindgren, Peter; Kiserud, Torvid; Acharya, Ganesh (Journal article; Peer reviewed, 2021)Introduction: In the fetus, a large proportion of the superior vena cava blood flow (QSVC) comes from the brain. To provide the possibility of using this blood flow as a representation of fetal brain circulation, we aimed ... -
Heart function by M-mode and tissue Doppler in the early neonatal period in neonates with fetal growth restriction
Nestaas, Eirik; Bjarkø, Lisa; Kiserud, Torvid; Haugen, Guttorm Nils; Fugelseth, Drude (Journal article; Peer reviewed, 2023)Background: Fetal growth restricted (FGR) neonates have increased risk of circulatory compromise due to failure of normal transition of circulation after birth. Aim: Echocardiographic assessment of heart function in FGR ... -
