Purpose Of Review: This article reviews our current understanding of amniotic fluid embolism (AFE), specifically the pathogenesis, treatment strategies, potential diagnostic tests and future therapeutic interventions for AFE.
Recent Findings: The incidence and case mortality of AFE varies widely because of heterogeneous diagnostic criteria and varying reporting mechanisms across the world. Amniotic fluid embolism is thought to be caused by abnormal activation of immunologic mechanisms following entry of fetal antigens into maternal circulation. Mast cell degranulation and complement activation may play a role in this anaphylactoid or systemic inflammatory response syndrome. Development of serum biomarkers and immune-histochemical staining techniques to aid diagnosis and develop treatments are under development and evaluation. Treatment of AFE is supportive and directed at treating cardiovascular, pulmonary, and coagulation derangements. Treatment for coagulopathy (fresh frozen plasma, cryoprecipitate/fibrinogen concentrate, and antifibrinolytics) should be initiated promptly. Recombinant factor VIIa may lead to increased mortality and should not routinely be used. C1 esterase inhibitors may be a potential therapeutic option.
Summary: AFE is a devastating obstetric complication that requires early and aggressive intervention with optimal cardiopulmonary resuscitation, as well as hemorrhage and coagulopathy management. Biomarkers offer promise to aid the diagnosis of AFE, and immunomodulation may provide future therapeutic interventions to treat this lethal condition.

Maternal diet has long-term effects on offspring brain development and behavior. Sucrose (table sugar) intakes are high in modern diets, but it is not clear how a maternal high-sucrose diet (HSD) affects the offspring. In rats, a maternal HSD (26% of calories from sucrose, which is human-relevant) alters maternal metabolism and brain and also alters adult offspring endocrinology and behavior in a sex-specific manner.

Objective: This study aims to assess the diagnostic efficacy of a combined approach integrating chromosomal karyotyping, copy number variation sequencing (CNV-seq), and quantitative fluorescence polymerase chain reaction (QF-PCR) in detecting chromosomal abnormalities in high-risk pregnancies.
Methods: This retrospective study analyzed 617 high-risk pregnancies undergoing prenatal diagnosis from February 2023 to August 2024, with amniotic fluid samples concurrently analyzed using karyotyping, CNV-seq, and QF-PCR. We evaluated clinical characteristics, diagnostic yields, and inter-method concordance rates.

BACKGROUND Ureaplasma urealyticum (UU) is a common microorganism that has been associated with a variety of obstetric and neonatal complications, such as infertility, stillbirth, histologic chorioamnionitis, neonatal sepsis, respiratory infections, and central nervous system infections. However, it is rare for it to cause severe neonatal asphyxia. This rarity is the focus of our case report, which aims to highlight the potential severity of UU infections in newborns.

Intra-amniotic infection (IAI), also known as chorioamnionitis, is a major cause of maternal and neonatal infection that occurs during pregnancy, labor and delivery, or in the postpartum period. Conditions such as meconium-stained amniotic fluid (MSAF) and premature rupture of membranes (PROMs) are recognized risk factors for amniotic fluid infection. This study identifies the microbial patterns in the amniotic fluid of women with PROMs and MSAF to determine the presence and types of bacterial growth.

Mesenchymal stem cells (MSCs) are multipotent cells with the potential to differentiate into various lineages. They have also the potential to protect themselves against harmful stimuli to maintain their functional integrity. Drug resistance-related transporters such as ABCB1 (P-glycoprotein; P-gp), ABCC1 (MRP1; multidrug resistance-related Protein 1), and LRP (lung resistance protein) may protect MSCs against toxic substances such as chemotherapeutic agents.
