Postpartum hemorrhage (PPH) is a leading cause of maternal morbidity and mortality. Routine treatment of PPH includes uterotonics, tranexamic acid, curettage, uterine (balloon) tamponade, compression sutures, uterine artery ligation, and, if available, transcatheter arterial embolization (TAE). In cases of severe PPH refractory to standard medical and surgical management, hysterectomy is usually the ultima ratio, and is equally associated with a higher rate of complications.

  • The study analyzed the use of prescribed medications among pregnant women in Switzerland from 2015 to 2021 using the Helsana claims database, focusing on various periods such as pre-pregnancy, pregnancy, and postpartum.
  • A significant finding was that 87.5% of the 34,584 participants claimed at least one drug during pregnancy, with 33.3% claiming five or more, highlighting a higher drug usage compared to pre-pregnancy and a similar rate postpartum.
  • The research emphasizes the need for careful consideration of the safety and effectiveness of prescribed drugs for pregnant women, as many of the most frequently prescribed medications differ from those typically used before or after pregnancy.

Introduction: Perinatal mental health disorders (PMDs) are a global health concern. In industrialized countries, the prevalence of PMDs is estimated to be 20%, and they are associated with serious negative effects for women, their children and their families, along with high societal costs related to long-term impacts. In Switzerland, the PMD detection rate during obstetrical healthcare provision is very low (1-3%), and specialized healthcare services are limited.

Perinatal white matter injury (WMI) is the leading cause of long-term neurological morbidity in infants born preterm. Neuroinflammation during a critical window of early brain development plays a key role in WMI disease pathogenesis. The mechanisms linking inflammation with the long-term myelination failure that characterizes WMI, however, remain unknown.

  • The study aimed to assess the effectiveness and safety of recombinant activated factor VIIa (rFVIIa) for treating severe postpartum hemorrhage (sPPH) through a multi-center randomized controlled trial and observational studies.
  • In the RCT, a significantly lower percentage of women treated with rFVIIa required invasive procedures compared to those who did not receive the treatment, although this was not confirmed in the observational studies.
  • Safety analysis revealed no increase in thromboembolic events for rFVIIa-treated women compared to non-treated women, indicating that while the efficacy may vary, the treatment is relatively safe.

Objectives: There have been significant advances in the medical management of severe postpartum hemorrhage (sPPH) over recent decades, which is reflected in numerous published guidelines. To date, many of the currently available national and international guidelines recommend recombinant factor VIIa (rFVIIa) to be used only at a very late stage in the course of sPPH, as a "last resort", before or after hysterectomy. Based on new safety data, rFVIIa has recently been approved by the European Medicines Agency (EMA) and Swissmedic for use in sPPH, if uterotonics are insufficient to achieve hemostasis, which in fact is significantly earlier in the course of postpartum hemorrhage (PPH).

White matter injury (WMI) is a common neurological issue in premature-born neonates, often causing long-term disabilities. We recently demonstrated a key beneficial role of Wharton's jelly mesenchymal stromal cell-derived small extracellular vesicles (WJ-MSC-sEVs) microRNAs (miRNAs) in WMI-related processes in vitro. Here, we studied the functions of WJ-MSC-sEV miRNAs in vivo using a preclinical rat model of premature WMI.

Artificial intelligence (AI) is gaining increasing interest in the field of medicine because of its capacity to process big data and pattern recognition. Cardiotocography (CTG) is widely used for the assessment of foetal well-being and uterine contractions during pregnancy and labour. It is characterised by inter- and intraobserver variability in interpretation, which depends on the observers' experience.

Introduction: Switzerland was amongst the first countries to offer cell-free fetal DNA (cffDNA) testing covered by the health insurance to pregnant women with a risk ≥ 1:1000 for trisomies at first trimester combined screening (FTCS). The aim of this study is to evaluate the implementation of this contingent model in a single tertiary referral centre and its effect on gestational age at diagnosing trisomy 21.

Materials And Methods: Between July 2015 and December 2020 all singleton pregnancies at 11-14 weeks of gestation without major fetal malformation were included and stratified according to their risk at FTCS.

Postpartum hemorrhage (PPH) remains a major cause of maternal morbidity and mortality. While PPH treatment guidelines exist, data on their effect on reduction in red blood cell (RBC) transfusions and use of hemostatic products are scarce. Continuous evaluation of PPH management is important to assess potential pitfalls and incorporate new treatment options.

Background: Microbiota composition is fundamental to human health with the intestinal microbiota undergoing critical changes within the first two years of life. The developing intestinal microbiota is shaped by maternal seeding, breast milk and its complex constituents, other nutrients, and the environment. Understanding microbiota-dependent pathologies requires a profound understanding of the early development of the healthy infant microbiota.
