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 ... -
Effects of applying universal fetal growth standards in a Scandinavian multi-ethnic population
Sletner, Line; Kiserud, Torvid; Vangen, Siri; Nakstad, Britt; Jenum, Anne Karen (Peer reviewed; Journal article, 2018-02)Introduction: The question of whether universal growth charts can be used in multi‐ethnic settings is of general interest. The Intergrowth‐21st fetal growth and newborn size standards are suggested to represent optimal ... -
Factors associated with health facility childbirth in districts of Kenya, Tanzania and Zambia: a population based survey
Phiri, Selia Ng’anjo; Kiserud, Torvid; Kvåle, Gunnar; Byskov, Jens; Evjen-Olsen, Bjørg; Michelo, Charles Cheembo; Echoka, Elizabeth; Fylkesnes, Knut (Peer reviewed; Journal article, 2014-07-04)Background: Maternal mortality continues to be a heavy burden in low and middle income countries where half of all deliveries take place in homes without skilled attendance. The study aimed to investigate the underlying ... -
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 ... -
Musculoskeletal sequelae in patients with obstetric fistula - a case-control study
Tennfjord, Merete Kolberg; Muleta, Mulu; Kiserud, Torvid (Peer reviewed; Journal article, 2014-11-08)Background: Obstetric fistula is essentially a result of pelvic injury caused by prolonged obstructed labour. Foot drop and walking difficulties in some of these women signify that the injury may extend beyond the loss of ... -
Prediction of adverse perinatal outcome of small-forgestational- age pregnancy using size centiles and conditional growth centiles
Karlsen, Henriette Odland; Johnsen, S. L.; Rasmussen, Svein; Kiserud, Torvid (Peer reviewed; Journal article, 2016-08)Objective: To test whether adding conditional growth centiles to size centiles of estimated fetal weight (EFW) improves prediction of adverse perinatal outcome in pregnancies with or at risk of having a small-for-gestational-age ... -
Reference ranges for head circumference in ethiopian children 0-2 years of age
Amare, Ephrem Bililigne; Idsøe, Mari; Wiksnes, Miriam; Moss, Thomas; Roelants, Mathieu; Shimelis, Damte; Juliusson, Petur Benedikt; Kiserud, Torvid; Wester, Knut (Peer reviewed; Journal article, 2015-12)BACKGROUND: Head circumference (HC) charts are important for early detection of hydrocephalus during childhood. In low-income countries where populationbased HC charts are rarely available, hydrocephalus occurs more commonly ... -
Rural-urban inequity in unmet obstetric needs and functionality of emergency obstetric care services in a Zambian district
Nganjo Phiri, Selia; Fylkesnes, Knut; Moland, Karen Marie; Byskov, Jens; Kiserud, Torvid (Peer reviewed; Journal article, 2016-01-29)Background: Zambia has a high maternal mortality ratio, 398/100,000 live births. Few pregnant women access emergency obstetric care services to handle complications at childbirth. We aimed to assess the deficit in life-saving ... -
Sex differences in umbilical artery Doppler indices: A longitudinal study
Widnes, Christian; Flo, Kari; Wilsgaard, Tom; Kiserud, Torvid; Acharya, Ganesh (Peer reviewed; Journal article, 2018-04-18)Background Sexual dimorphism in placental size and function has been described. Whether this influences the clinically important umbilical artery (UA) waveform remains controversial, although a few cross-sectional studies ... -
Sex-specific reference ranges of cerebroplacental and umbilicocerebral ratios: A longitudinal study
Acharya, Ganesh; Ebbing, Cathrine; Karlsen, Henriette Odland; Kiserud, Torvid; Rasmussen, Svein (Peer reviewed; Journal article, 2020)Objectives: Observational studies have shown that low cerebroplacental ratio (CPR) values predict an increased risk of adverse perinatal outcome. The inverse ratio, i.e. the umbilicocerebral ratio (UCR), has been suggested ... -
Stillbirths at a hospital in Nablus, 2010: a cohort study
Cung, Tam Giao; Paus, Anne Sofie; Aghbar, Ammar; Kiserud, Torvid; Hinderaker, Sven Gudmund (Peer reviewed; Journal article, 2014-09-05)Background: Stillbirths are insufficiently reported in many countries. In Nablus, reporting has recently started; little is published in Palestine on the stillbirth rate and its risk factors. Objective: To study the rate ... -
Use of conditional centiles of middle cerebral artery pulsatility index and cerebroplacental ratio in the prediction of adverse perinatal outcomes
Karlsen, Henriette Odland; Ebbing, Cathrine; Rasmussen, Svein; Kiserud, Torvid; Johnsen, Synnøve L. (Journal article, 2016-06)Introduction. Centiles of middle cerebral artery pulsatility index and cerebroplacental ratio are useful for predicting adverse perinatal outcomes. A ‘conditional centile’ is conditioned by a previous measurement reflecting ... -

However, major determinants for perinatal outcomes and postnatal growth are laid down during antenatal development. ... -
