Summary: Survivors of preterm birth face various disabilities, and addressing the rates of low birth weight, neonatal and maternal morbidities and mortalities is crucial. Research has provided theories on risk factors and clinical manifestations, but there is a lack of biomarkers for early diagnosis. To overcome current limitations, an integrated approach studying the network interaction between different tissues and organs is needed.

Summary: This study investigates the factors associated with premature birth and low birth weight in an Ecuadorian tertiary hospital. The findings show a higher proportion of low birth weight and preterm births compared to studies conducted in Latin America. Younger mothers, illiterate mothers, and those with gestational hypertension are more likely to have low birth weight newborns, while older mothers are more likely to have large-for-gestational-age infants. Maternal obesity and gestational diabetes are also associated with an increased percentage of large-for-gestational-age births.

Summary: This study aimed to characterize the transcriptome of equine chorioallantois during spontaneous labor and compare it with that of normal preterm chorioallantois. The results showed differential gene expression between labor and preterm, with upregulation of proinflammatory mediators and matrix metalloproteinases, and downregulation of collagens. This study provides insights into the molecular mechanisms underlying labor in horses.

Summary: By analyzing the transcriptomic data, it was found that women undergoing term labor exhibit labor-specific gene expression changes in their peripheral blood, which correlate with gene changes in the chorioamniotic membranes, myometrium, and cervix, partially overlapping with changes observed in asymptomatic women prior to preterm birth, potentially serving as a tool for assessing labor status and identifying preterm birth risk.

Summary: This study analyzed the coexistence and prevalence of obstetric interventions in maternity hospitals in Belo Horizonte City, as well as investigated sociodemographic and obstetric factors associated with these interventions. The results highlighted two conflicting obstetric profiles, one including beneficial practices and the other including harmful or ineffective practices. The study emphasized the persistence of an obstetric care model not based on scientific evidence.

Summary: The study found correlations between sow traits such as backfat thickness, number and weight of placenta parts, parturition duration, and placenta expulsion duration. The expulsion of the first placenta part was also related to the timing of the last piglet's birth. Additionally, placental efficiency was associated with the number of liveborn piglets.

Summary: Retained fetal membranes (RFM) in mares is a complex post-partum disease with unclear pathogenesis. This study used RNA sequencing to compare genes expressed in the placenta of mares with RFM and those without, revealing potential pathways involved in apoptosis, inflammation, and extracellular matrix metabolism. Results suggest that further research into these differential gene expressions may help in understanding the pathogenesis of RFM.

Summary: This study developed a mouse model of ascending infection and inflammation associated with preterm birth. Clinically, these models can help understand the mechanism of infection-related preterm birth, determine intervention targets, or identify potential biomarkers for predicting high-risk pregnancy status early in pregnancy.

Summary: Preterm birth is a global epidemic and factors such as maternal nutrition and placental-infant TL influence the risk of PTB. Maternal nutrition affects PTB risk through its influence on maternal TL. PTB also independently affects TL regulation in offspring. However, the strength of these associations and the influence of other factors remain unclear. Whether maternal TL is simply a biomarker of maternal nutrition status and PTB risk or a causative factor of PTB is yet to be determined.

Summary: Parturition signals the end of immune tolerance in pregnancy. The activation of placental inflammasome differs in terms of mode of delivery and neonatal sex. Assessing placental inflammasome activation may identify babies who have been exposed to aberrant inflammation at birth.

Summary: By creating and validating a high-fidelity pregnant rat model, researchers have successfully simulated the process of labor induction with oxytocin and conducted experimental studies on labor-related issues. Their findings suggest that there is no significant oxidative stress in the newborn brain during labor induction with oxytocin.

Summary: This prospective cohort study aimed to determine the technology-free predictors of preterm birth in singleton women with threatened preterm labor. Seven variables were determined as predictors: rupture of membranes, cervical dilation, gravidity, psychological violence during pregnancy, medical problems in pregnancy onset, vaginal bleeding/spotting, and woman age. These factors seem to have moderate power in predicting preterm birth in singleton pregnant women.

Summary: Although inflammation is present during term labor, it may not be the initiating signal. Further research is needed to understand the processes underlying normal labor. Inconsistencies in defining the onset of labor should be addressed.

Summary: Preterm birth is the leading cause of mortality and morbidity in newborns and children under 5. Identifying the specific mechanisms underlying labor initiation, including fetal origin factors, is crucial for improving preterm infant outcomes.

Summary: The study explored the relationship between SDF2 expression and ER response in placental cells exposed to hyperglycaemia, with findings indicating an increase in SDF2 expression in GDM placentae treated with diet but not with insulin therapy. Furthermore, high glucose reduced SDF2 expression in BeWo cells, while insulin treatment reversed the increase in ER stress factors CHOP and sXBP1 induced by high glucose. These results highlight the importance of insulin in mitigating ER stress in placental cells under hyperglycaemic conditions.

Summary: The study utilized quantitative proteomics analysis to investigate the impact of ZIKV infection on placental cells, revealing altered levels of proteins involved in cell proliferation, apoptosis, and inflammatory processes. The findings suggest that antibody-opsonized ZIKV particles may play a pivotal role in determining infection outcomes and the role of mixed infections, providing valuable insights for infection control strategies.

Summary: In this study, an analysis of exosome-enriched maternal plasma showed potential for early diagnosis of hypertensive disorders of pregnancy (HDP) using Raman spectroscopy and proton nuclear magnetic resonance metabolomics. Significant differences in metabolite levels were found in HDP patients, as indicated by Raman bands intensity and H-1 NMR analysis results. The study suggested that analyzing exosome-enriched plasma could be useful for assessing placental function and identifying early biomarkers for HDP.

Summary: This study evaluated the relationship between the expression of CRIPTO-1 and the degree of trophoblast invasion into the tubal wall. The results showed that the quantitative expression of CRIPTO-1 differed in different degrees of trophoblast invasion. Deeper invasion was associated with stronger expression of CRIPTO-1.
