Folic acid intervention during pregnancy alters DNA methylation, affecting neural target genes through two distinct mechanisms.

Clin Epigenetics 2022 May 16;14(1):63. Epub 2022 May 16.

Genomic Medicine Research Group, Ulster University, Coleraine, Northern Ireland, UK.

Background: We previously showed that continued folic acid (FA) supplementation beyond the first trimester of pregnancy appears to have beneficial effects on neurocognitive performance in children followed for up to 11 years, but the biological mechanism for this effect has remained unclear. Using samples from our randomized controlled trial of folic acid supplementation in second and third trimester (FASSTT), where significant improvements in cognitive and psychosocial performance were demonstrated in children from mothers supplemented in pregnancy with 400 µg/day FA compared with placebo, we examined methylation patterns from cord blood (CB) using the EPIC array which covers approximately 850,000 cytosine-guanine (CG) sites across the genome. Genes showing significant differences were verified using pyrosequencing and mechanistic approaches used in vitro to determine effects on transcription. Read More

Changes in Serum Levels of Ketone Bodies and Human Chorionic Gonadotropin during Pregnancy in Relation to the Neonatal Body Shape: A Retrospective Analysis.

Nutrients 2022 May 9;14(9). Epub 2022 May 9.

Department of Obstetrics and Gynecology, Graduate School of Medicine, Hokkaido University, Sapporo 060-8638, Japan.

Among the physiological changes occurring during pregnancy, the benefits of morning sickness, which is likely mediated by human chorionic gonadotropin (HCG) and induces serum ketone production, are unclear. We investigated the relationship between serum levels of ketone bodies and HCG in the first, second, and third trimesters and neonatal body shape (i.e. Read More

Chronic Inflammatory Placental Disorders Associated With Recurrent Adverse Pregnancy Outcome.

Front Immunol 2022 22;13:825075. Epub 2022 Apr 22.

Elizabeth Garrett Anderson Institute for Women's Health, Department of Maternal and Fetal Medicine, University College London, London, United Kingdom.

Chronic inflammatory placental disorders are a group of rare but devastating gestational syndromes associated with adverse pregnancy outcome. This review focuses on three related conditions: villitis of unknown etiology (VUE), chronic histiocytic intervillositis (CHI) and massive perivillous fibrin deposition (MPFD). The hallmark of these disorders is infiltration of the placental architecture by maternal immune cells and disruption of the intervillous space, where gas exchange between the mother and fetus occurs.

Impact of replacing or adding pregnancy-associated plasma protein-A at 11-13 weeks on screening for preterm pre-eclampsia.

Ultrasound Obstet Gynecol 2022 Apr 25. Epub 2022 Apr 25.

Department of Obstetrics and Gynaecology, The Chinese University of Hong Kong, Hong Kong, SAR, China.

Objectives: To assess whether pregnancy associated plasma protein-A (PAPP-A) improves or provides equivalent screening performance as placental growth factor (PlGF) when screening for preterm preeclampsia (PE) at 11-13 weeks METHODS: This is a secondary analysis of a non-intervention screening study of 6546 singleton pregnancies prospectively screened for preterm PE in the first trimester between December 2016 and June 2018. Patient-specific risks for preterm PE were estimated by maternal history, mean arterial pressure (MAP), uterine artery pulsatility index (UtA-PI), PlGF and PAPP-A. A competing risks model with biomarker expressed in multiple of expected median (MoM) was used. Read More

Can Ultrasound Analysis of the Yolk Sac be a Predictor of Pregnancy Outcome?

Curr Health Sci J 2021 Oct-Dec;47(4):547-552. Epub 2021 Dec 31.

Department of Obstetrics and Gynecology, University of Medicine and Pharmacy of Craiova, Romania.

The Yolk sac is the first source of transfer between the mother and the embryo, with a nutritional and gas exchange function, vital for the development of the embryo, to which we can add primitive hematopoiesis, the production of stem cells and germ cells. Although normal-term pregnancies with abnormal aspects of the yolk sac have been described, the smaller or larger size of the yolk sac is associated with pregnancy loss. Our study aimed to determine whether the yolk sac size change, determined by measuring diameter (2D ultrasonography) or volume (3D ultrasonography), is independently associated with adverse pregnancy outcomes.

Live Birth Rate in Women with Recurrent Pregnancy Loss after In Vitro Fertilization with Concomitant Intravenous Immunoglobulin and Prednisone.

J Clin Med 2022 Mar 29;11(7). Epub 2022 Mar 29.

Department of Obstetrics and Gynecology, Aalborg University Hospital, Reberbansgade 15, 9000 Aalborg, Denmark.

Pregnancy loss after in vitro fertilization (IVF) is at least as common as after spontaneous conception. Recurrent pregnancy loss (RPL) may often have an immunological background, and it is therefore relevant to test immune-based interventions in these patients. The objective was to investigate the effect of immunotherapy with intravenous immunoglobulin (IvIg) and prednisone (PRS) as concomitant therapy to IVF in women with RPL after earlier IVF treatments.

Laparoscopic abdominal cerclage during pregnancy: a simplified approach.

Am J Obstet Gynecol 2022 Mar 23. Epub 2022 Mar 23.

Key Laboratory of Reproductive Genetics (Ministry of Education) and Department of Obstetrics, Women's Hospital School of Medicine Zhejiang University, Hangzhou, China. Electronic address:

Cervical insufficiency is a major cause of second-trimester pregnancy loss and spontaneous preterm delivery. Transabdominal cervicoisthmic cerclage is usually performed before pregnancy for patients of cervical insufficiency, in whom transvaginal cervical cerclage procedure cannot be placed or has failed previously. Performing a transabdominal cerclage becomes a huge challenge owing to the enlargement of the pregnant uterus in patients who were indicated for transabdominal cervicoisthmic cerclage but were missed before pregnancy.
