Article Synopsis
  • - Progestin-primed ovarian stimulation (PPOS) is a method that helps manage the premature surge of luteinizing hormone (LH) during the follicular phase, using micronized progesterone or progestins instead of traditional hormone treatments.
  • - A review of studies from 2015 to 2021 indicates that PPOS can lead to better outcomes in in-vitro fertilization (IVF), including more embryos, lower risks of ovarian hyperstimulation syndrome (OHSS), and comparable retrieval rates.
  • - The benefits of PPOS appear to be particularly significant for specific groups, such as poor ovarian responders and women with polycystic ovary syndrome (PCOS), indicating its effectiveness in assisted reproductive

Importance: Antiphospholipid syndrome in neonates and children is a rare, but in some cases life-threatening condition with arterial and/or venous thrombosis and/or non-thrombotic neurological, skin, ophthalmological and other manifestations.

Observations: This review highlights the available information about the features of pediatric APS, including the rare catastrophic form, the differences between pediatric and adult APS, and the role of genetic thrombophilia in APS manifestation.

Conclusions And Relevance: The clinical manifestations and treatment options for APS in children may differ from those in adults, and prescribing therapy can be challenging due to the unique clinical and morphological characteristics of the pediatric patient.

This review was based on a symposium that examined novel aspects of the microbiome during pregnancy and early life and explored papers published by the lecturers. For example, it showed that bacterial extracellular vesicles derived from the microbiome harboured in various maternal niches, carried bacterial deoxyribonucleic acid, were isolated from the placenta and may have confounded placental microbiome studies. Maternal diet was responsible for the composition and diversity of breast milk microbiota, and may have shaped the offspring's microbiome and influenced their immune components.

Article Synopsis
  • This study looked at how taking a hormone called micronized progesterone (VMP4) can help pregnant women with low levels of a protein called PAPP-A during early pregnancy.
  • 116 pregnant women were divided into three groups: one group took VMP4 for a short time, another for a longer time, and the last group did not take it at all.
  • The results showed that the women who didn't take VMP4 had more problems like miscarriages and other complications, while those who took it had healthier pregnancies and babies.

Article Synopsis
  • Umbilical cord knots are significant for fetal outcomes, affecting both singleton and twin pregnancies, but they often go unnoticed during prenatal scans due to their silent clinical manifestations.
  • Although ultrasonographers may overlook the cord during routine obstetric ultrasounds, improved technology allows for better fetal assessments, making it essential to evaluate the umbilical cord more carefully.
  • The review covers the causes and risk factors of umbilical cord knots, ultrasound detection methods, management opinions, and the impact of knot characteristics on pregnancy outcomes.

Article Synopsis
  • * Pregnant women with low omega-3 intake are at higher risk for preterm birth, and should start this increased intake preferably by the second trimester and continue until close to delivery.
  • * Identifying women with low omega-3 levels can be done through standardized intake questions or blood tests, and information on achieving the right intake should be shared with women and their partners.

Today, there is strong and diversified evidence that in humans at least 50% of early embryos do not proceed beyond the pre-implantation period. This evidence comes from clinical investigations, demography, epidemiology, embryology, immunology, and molecular biology. The purpose of this article is to highlight the steps leading to the establishment of pregnancy and placenta formation.

Article Synopsis
  • Placenta accreta spectrum disorders lead to high maternal complications and often result in hysterectomy, emphasizing the need for improved surgical techniques.
  • The study introduced a new uterine-preserving method during cesarean delivery, comparing outcomes between this technique and the older approach used until 2014.
  • Results showed the new method significantly reduced blood loss, transfusions, bladder injuries, hospital stays, and hysterectomy rates, proving it to be more effective than previous techniques.

Article Synopsis
  • The COVID-19 pandemic has heightened maternal health risks, leading to complications such as preterm births, gestational diabetes, and stillbirths in infected pregnant women.
  • Research indicates that the infection can lead to specific changes in placental tissue, potentially affecting pregnancy outcomes through inflammation and vascular injuries.
  • Histopathological examination of the placenta is crucial for understanding the mechanisms behind adverse perinatal outcomes and investigating possible connections between maternal infection and placental abnormalities, although evidence remains inconclusive.

Introduction: Prenatal screening programs are important components for pregnant women care and are often linked with grief and shock based on gestational age or the diagnosis. Lower/no sensitivity is also associated with these screening programs leading to providing false-negative outputs.

Case Presentation: Present work shows a case of missed antenatal diagnosis of Down syndrome and its persistant medical and psychological impact on the family members.

Article Synopsis
  • Human amniotic fluid extracellular vesicles (HAF-EVs) from pregnant women show anti-inflammatory effects on T cells and monocytes, but their specific functions are not fully understood.
  • * The study aimed to explore how HAF-EVs impact inflammasome activation in human monocytes, finding that these vesicles contain immunoregulatory molecules and small amounts of endotoxin, potentially linked to specific bacterial strains.
  • * Results indicate that HAF-EVs can activate inflammasomes in THP-1 cells, but subsequent treatments can inhibit this activation, suggesting HAF-EVs may play a role in immune regulation during early pregnancy.

of recommendationsCorticosteroids should be administered to women at a gestational age between 24 and 33weeks, when preterm birth is anticipated in the next seven days, as these have been consistently shown to reduce neonatal mortality and morbidity. (Strong-quality evidence; strong recommendation). In selected cases, extension of this period up to 34weeks may be considered (Expert opinion).

Article Synopsis
  • The text emphasizes that GDP does not account for the unpaid work mainly performed by women, which is crucial for societal well-being and should be considered when evaluating maternal, newborn, child, and adolescent health (MNCAH).
  • Experts at The Venice Forum agreed that recognizing women's unpaid work could enhance GDP by reflecting its positive impact on health and prosperity across generations.
  • The authors argue for a reevaluation of economic progress metrics to include societal contributions, especially in light of contemporary challenges like COVID-19, climate change, and conflict.

Article Synopsis
  • HtrA1 is a serine-protease protein expressed in various tissues, particularly the placenta, and its levels are higher in early pregnancy, indicating a potential role in placental development and gestational diabetes (GDM).
  • A study analyzed HtrA1 serum levels during both the first (10-12 weeks) and third trimesters (36-40 weeks) in women, comparing normal pregnancies to those with GDM.
  • Results showed that higher HtrA1 levels were linked to GDM both in the third trimester and as an early indicator in the first trimester, suggesting HtrA1 could serve as an effective marker for predicting GDM.

During pregnancy, a woman's immune system adapts to the changing hormonal concentrations, causing immunologic transition. These immunologic changes are required for a full-term pregnancy, preserving the fetus' innate and adaptive immunity. Preterm labor, miscarriage, gestational diabetes mellitus, and pre-eclampsia are all caused by abnormal cytokine expression during pregnancy and childbirth.
