    • Agreement between preload reserve measured by impedance cardiography and echocardiography during pregnancy 

      Liang, Huan; Vårtun, Åse; Acharya, Ganesh (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-04-05)
      <i>Purpose</i>: Accurate assessment of cardiac function is important during pregnancy. Echocardiography and impedance cardiography (ICG) are commonly used noninvasive methods to measure stroke volume (SV) and cardiac output (CO). The diference in stroke volume (ΔSV) or cardiac output (ΔCO) measured at baseline and after passive leg raising (PLR) is a measure of preload reserve that predicts volume ...

    • Implementation of international society guidelines on chorionicity determination in twins: A multi-Center cohort study in mainland China

      Objective: Ultrasound determination of chorionicity is poor in early pregnancy in China. In an effort to increase the accuracy rate of prompt chorionicity determination, clinical training was provided to primary care physicians. This study assesses the effects of implementing clinical guidelines on chorionicity determination.<p> <p>Methods: A multi‑centered cohort study was conducted between ...

    • Maternal cardiac function, uterine artery hemodynamics and natriuretic peptides at 22-24 weeks of gestation and subsequent development of hypertensive disorders of pregnancy 

      Liang, Huan; Vårtun, Åse; Flo, Kari; Widnes, Christian; Acharya, Ganesh (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-12-26)
      <p><i>Introduction - </i>Maternal cardiac dysfunction as well as abnormal uterine artery (UtA) Doppler are associated with hypertensive disorders of pregnancy (HDP), but their relation is unclear. We investigated the correlation between maternal cardiac function, UtA hemodynamics and natriuretic peptides, and explored differences between women who subsequently developed HDP and those who did ...

    • Novel corona virus disease (COVID-19) in pregnancy: What clinical recommendations to follow? 

      Liang, Huan; Acharya, Ganesh (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-03-05)
      Pregnancy is a state of partial immune suppression which makes pregnant women more vulnerable to viral infections, and the morbidity is higher even with seasonal influenza. Therefore, the COVID‐19 epidemic may have serious consequences for pregnant women. Although the vast majority of cases of COVID‐19 are currently in China, the risk of outward transmission appears to be significantly raising global ...

    • Optimized cutoff maternal age for adverse obstetrical outcomes: A multicenter retrospective cohort study in Urban China during 2011 to 2012 

      Zhang, Xiaolei; Liang, Huan; Zhao, Huan-Qiang; Wu, Su-Wen; Zhou, Qiongjie; Li, Xiao-Tian (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-02-05)
      <p><i>Background: </i>China's two-child policy has led to a trend of aging in pregnancy which was associated with adverse outcomes. This study aimed to identify the clinically cutoff maternal age for adverse obstetric outcomes in China. <p><i>Methods: </i>This secondary analysis of a multicenter retrospective cohort study included data of childbearing women from 39 hospitals collected in urban China ...
