First trimester cervical angles for the prediction of spontaneous preterm birth.
Eur J Obstet Gynecol Reprod Biol
January 2025
Department of Obstetrics and Gynaecology, The Chinese University of Hong Kong, Hong Kong SAR, China; Shenzhen Research Institute, The Chinese University of Hong Kong, Hong Kong SAR, China. Electronic address:
Objective: First trimester cervical angles for the prediction of spontaneous preterm birth (sPTB) remains unclear. The objective is to explore the potential value of first trimester cervical angles for the prediction of sPTB.
Study Design: This was a secondary analysis of data derived from a prospective cohort study for sPTB screening in singleton pregnancies at 11 + 0-13 + 6 weeks in women attending routine Down's syndrome screening at Prince of Wales Hospital, Hong Kong SAR, between June 2018 and July 2020.
Third-trimester resolution of low placentation and risk of postpartum hemorrhage.
Eur J Obstet Gynecol Reprod Biol
January 2025
Montefiore Medical Center/Albert Einstein College of Medicine, Division of Fetal Medicine and Ultrasound, Department of Obstetrics and Gynecology and Women's Health.
Objective: Low placentation is associated with increased risk of postpartum hemorrhage (PPH). There is a paucity of data on the association between second trimester low placentation that later resolves, and PPH. Our objective was to investigate the association of resolved low placentation and other prenatal ultrasound markers, and PPH with delivery.

Front Immunol
January 2025
Department of Microbiology, Immunology and Molecular Genetics, University of Kentucky, Lexington, KY, United States.
Introduction: The immune compartment within fetal chorionic villi is comprised of fetal Hofbauer cells (HBC) and invading placenta-associated maternal monocytes and macrophages (PAMM). Recent studies have characterized the transcriptional profile of the first trimester (T1) placenta; however, the phenotypic and functional diversity of chorionic villous immune cells at term (T3) remain poorly understood.
Methods: To address this knowledge gap, immune cells from human chorionic villous tissues obtained from full-term, uncomplicated pregnancies were deeply phenotyped using a combination of flow cytometry, single-cell RNA sequencing (scRNA-seq, CITE-seq) and chromatin accessibility profiling (snATAC-seq).
Maternal cell-free DNA in early pregnancy for preeclampsia screening: a systematic review.
Arch Gynecol Obstet
January 2025
Faculty of Medicine and Health Sciences, Tel Aviv University, Tel Aviv, Israel.
Purpose: To quantify the separation between maternal blood cell-free (cf)DNA markers in preeclampsia and unaffected pregnancies and compare with existing markers. This approach has not been used in previous studies.
Methods: Comprehensive systematic literature search of PubMed to identify studies measuring total cfDNA, fetal cf(f)DNA or the fetal fraction (FF) in pregnant women.
Aortoiliac arterial thrombosis and renal artery stenosis in a patient with neonatal multisystem inflammatory syndrome: a case report and review of literature.
Front Pediatr
January 2025
Division of Neonatology, Department of Pediatrics, Faculty of Medicine Vajira Hospital, Navamindradhiraj University, Bangkok, Thailand.
Background: Multisystem inflammatory syndrome in neonates (MIS-N) is a rare condition thought to be associated with prenatal exposure to maternal severe acute respiratory syndrome coronavirus 2 infection. This immune-mediated hyperinflammation has been described in neonates with multiorgan dysfunction, including cardiopulmonary, encephalopathy, coagulopathy, and vascular complications. However, renovascular complications in MIS-N are rare.
