In multiple gestations, intrauterine death of one fetus occurs frequently. Sonographic studies indicate that many twin pregnancies are converted in early pregnancy to singletons. The "vanished" twin is sometimes recognized as a fetus papyraceous (compressus) incorporated into the placenta of the survivor. Death of one twin later in pregnancy may have serious implications for the survivor, especially in cases of monochorionic twins. One postulated mechanism has been that thromboplastic proteins from the dead twin are transfused into the survivor's circulation, resulting in disseminated intravascular coagulation. More recently it has been proposed that massive blood loss may occur from the survivor into the more relaxed circulation of a dead monochorionic twin through vascular anastomoses. These mechanisms may explain the higher frequency of cerebral palsy in monochorionic twins. These concepts emphasize the importance of careful examination and thoughtful interpretation of twin placentas.

Prenatal diagnosis and treatment of fetal intestinal volvulus: A case report.
Medicine (Baltimore)
January 2025
Department of Neonatology, Hangzhou Women's Hospital, Hangzhou, Zhejiang, China.
Rationale: Fetal intestinal volvulus, a rare and severe disorder, poses significant diagnostic challenges prenatally and can lead to intrauterine death or adverse neonatal outcomes if untreated in a timely manner. This study reports a case of fetal intestinal volvulus confirmed postoperatively, providing insights into its clinical manifestations, diagnostic methods, and treatment outcomes, thereby enhancing understanding of this rare condition.
Patient Concerns: A Chinese gravida 2, para 1 female presented at 32 weeks and 5 days of gestation with decreased fetal movements.
Pregnancy and cardiovascular outcomes among patients post Fontan surgery: a 25-year single-centre retrospective cohort study.
Open Heart
January 2025
Department of Cardiology, Rabin Medical Center, Petah Tikva, Israel.
Introduction: Data on the characteristics and outcomes of pregnancy and among patients with Fontan physiology are limited. We aimed to evaluate the immediate and long-term outcomes among these patients who were followed at our centre.
Methods: We included adult patients who had undergone Fontan surgery for congenital heart disease and were pregnant between 1994 and 2021.
Plasma transfusions in neonatal intensive care units: a prospective observational study.
Arch Dis Child Fetal Neonatal Ed
January 2025
Division of Neonatology, Willem-Alexander Children's Hospital, Leiden University Medical Center, Leiden, The Netherlands
Objective: Despite lack of evidence supporting efficacy, prophylactic fresh frozen plasma and Octaplas transfusions may be administered to very preterm infants to reduce bleeding risk. International variation in plasma transfusion practices in neonatal intensive care units (NICUs) is poorly understood, therefore, we aimed to describe neonatal plasma transfusion practice in Europe.
Design: Prospective observational study.
Birth outcomes of advanced maternal age pregnancies.
Cent Eur J Public Health
December 2024
Department of Preclinical Subjects, Faculty of Health Sciences, Palacky University Olomouc, Olomouc, Czech Republic.
Objective: Pregnancy at advanced maternal age has become more common over the last decades. Therefore, the study aimed to describe the characteristics and maternal and perinatal outcomes of women giving birth at advanced maternal age and very advanced age.
Methods: We conducted a retrospective cohort study of 2,300 singleton births that occurred in 2020-2021 at the Department of Gynaecology and Obstetrics of the Louis Pasteur University Hospital in Košice.
Low-dose aspirin versus placebo in postpartum venous thromboembolism: a multi-national, pilot, randomised, placebo-controlled trial.
Lancet Haematol
January 2025
Department of Medicine, McGill University, Montreal, QC, Canada.
Background: Despite the morbidity and mortality of venous thromboembolism, there is little evidence to guide postpartum thromboprophylaxis in patients at moderate risk. We aimed to assess the feasibility of conducting a double-blind, randomised trial of aspirin versus placebo in postpartum individuals with two or more venous thromboembolism risk factors, mild-to-moderate thrombophilia, or both.
Methods: The pilot PARTUM trial, a multi-national, randomised, double-blind, placebo-controlled trial, was conducted in seven centres across Canada, France, Ireland, and the Netherlands.
