Divergent Regulation of Decidual Oxidative-Stress Response by NRF2 and KEAP1 in Preeclampsia with and without Fetal Growth Restriction
Mundal, Siv Boon; Rakner, Johanne Johnsen; Silva, Gabriela; Gierman, Lobke; Austdal, Marie; Basnet, Purusotam; Elschot, Mattijs; Bakke, Siril Skaret; Ostrop, Jenny; Thomsen, Liv Cecilie Vestrheim; Moses, Eric; Acharya, Ganesh; Bjørge, Line; Iversen, Ann-Charlotte (Journal article; Peer reviewed, 2022)Utero-placental development in pregnancy depends on direct maternal–fetal interaction in the uterine wall decidua. Abnormal uterine vascular remodeling preceding placental oxidative stress and placental dysfunction are ... -
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 ... -
ISUOG Practice Guidelines (updated): use of Doppler velocimetry in obstetrics
Bhide, Amarnath; Acharya, Ganesh; Baschat, Ahmet Alexander; Bilardo, Caterina Maddalena; Brezinka, Christoph; Cafici, Daniel; Ebbing, Cathrine; Hernandez-Andrade, Edgar A.; Kalache, Karim; Kingdom, John; Kiserud, Torvid; Surendran, Sailesh Kumar; Lee, Wesley; Lees, Christoph; Leung, Kwok Yin; Malinger, Gustavo; Mari, Giancarlo; Prefumo, Federico; Sepulveda, Waldo; Trudinger, Brian (Journal article; Peer reviewed, 2021) -
Reference ranges of fetal superior vena cava blood flow velocities and pulsatility index in the second half of pregnancy: a longitudinal study
Stefopoulou, Maria; Herling, Lotta; Johnson, Jonas; Lindgren, Peter; Kiserud, Torvid; Acharya, Ganesh (Journal article; Peer reviewed, 2021)Background Fetal superior vena cava (SVC) is essentially the single vessel returning blood from the upper body to the heart. With approximately 80-85% of SVC blood flow representing cerebral venous return, its interrogation ... -
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 ... -
Volume blood flow-based indices of fetal brain sparing in the second half of pregnancy: A longitudinal study
Stefopoulou, Maria; Johnson, Jonas; Wilsgaard, Tom; Lindgren, Peter; Herling, Lotta; Kiserud, Torvid; Acharya, Ganesh (Journal article; Peer reviewed, 2020)Introduction Cerebroplacental ratio (CPR) and umbilicocerebral ratio (UCR) are clinically used as a measure of fetal brain sparing. These are calculated as the ratios between the pulsatility indices (PIs) of middle cerebral ...
