A case of severe haemolytic disease of the fetus due to six rare alloantibodies is described. In a pregnant women at 23 weeks gestation after the finding of a positive indirect Coombs test maternal antibodies have been precisely identified and titrated: anti-I: 1/23, anti-c: 1/64, anti-S: 1/16, anti-Fya: 1/128, anti-M: 1/64, anti-Jka: 1/32000. Fetal blood group, free and red blood cell adherent antibodies have been investigated on fetal blood samples obtained by means of cord centesis. A compatible donor has been found. Severe fetal anemia has been corrected by ultrasound guided intrauterine transfusions (one abdominal and two intravascular transfusions) with positive outcome of the pregnancy.

Regulatory B-Cells Are Associated Negatively With Regulatory T-Cells and Positively With Cytokines in Peripheral Blood of Pregnant Women.

Problem: Regulatory B-cells (Bregs, CD19CD24CD38) are a specialized B-cell subset that suppresses immune responses and potentially contribute to the maintenance of an immune-privileged environment for fetal development during pregnancy. However, little is known about the surrounding immunological environment of Bregs in gestational physiology. The relationship of regulatory T-cells (Tregs, CD4CD25CD127FoxP3) to Bregs in coordinating immunoregulation during pregnancy is unknown.

Problem: Natural killer (NK) cells undergo education for full functionality via interactions between killer immunoglobulin-like receptors (KIRs) or NKG2A and human leukocyte antigen (HLA) ligands. Presumably, education is important during early pregnancy as insufficient education has been associated with impaired vascular remodeling and restricted fetal growth in mice. NK cell education is influenced by receptor co-expression patterns, human cytomegalovirus (CMV), the HLA-E107 dimorphism, and HLA-B leader peptide variants.

Objective: To compare low-cost "Suction Tube Uterine Tamponade" (STUT) treatment for refractory postpartum hemorrhage (PPH) with uterine balloon tamponade (UBT) using a randomized feasibility study.
Methods: After verbal assent, we allocated participants with refractory PPH by randomly ordered envelopes to STUT or routine UBT at 10 hospitals in South Africa and one tertiary referral center in Colombia between January 10, 2020, and May 3, 2024. In the STUT group, we inserted a 24 FG Levin stomach tube into the uterine cavity and applied suction.
Quantitative evaluation of placental microvascular blood flow and microstructure in fetal growth restriction with IVIM MRI.

Background: Intravoxel incoherent motion (IVIM) MRI uses diffusion-weighted (DW) MRI acquisitions to evaluate the microvascular and cellular environments of tissue. Due to these properties, IVIM has been increasingly utilized to evaluate abnormal placentation.
Objective: Our primary objective was to compare IVIM parameters in the placenta of patients with fetal growth restriction and appropriate for gestational age controls across gestational ages.

Purpose: We aimed to determine fetal liver perfusion in PGDM and GDM pregnancies and to assess the relation of ductus venosus (DV) shunt fraction with adverse pregnancy outcomes.
Methods: We conducted a prospective longitudinal observational study including 188 pregnant women: group I-patients with pregestational DM (PGDM, n = 86), group II-patients with gestational DM (GDM, n = 44), group III-control (n = 58). The patients included in the study underwent ultrasound examination at 30-40 weeks of pregnancy.
