Purpose: To compare total serum sialic acid (SA) levels between singleton pregnant women diagnosed with preterm labor between 24th and 36th weeks of pregnancy, singleton pregnant women at term, and their gestational age-matched controls.
Methods: Thirty pregnants diagnosed with preterm labor (group I), 30 gestational age-matched control pregnants (group II), 30 pregnants with labor at term (group III), and 30 gestational age-matched control pregnants (group IV) were enrolled. Detailed history, demographic data (age, gravidity, parity, abortion), ultrasound parameters, cervical dilatation and effacement, fetal tococardiography, routine laboratory tests, and total SA levels were assessed.
Results: There was no statistically significant difference between the parameters other than SA. SA levels of the preterm labor group (group I) were significantly higher than the other three groups.
Conclusions: We may suggest that pathways including SA or molecules containing SA in subclinical infection without the clinical manifestations of apparent infection may be involved in the pathogenesis of preterm birth. Future longitudinal studies are needed to investigate prediction performance and to better understand the role of SA in molecular mechanisms leading to preterm labor.

Objective: To study the implementation value of abdominal B-ultrasound combined with cervical cerclage in the prevention and treatment of recurrent late abortion.
Methods: From October 2020 to December 2023, 196 pregnant patients who had a history of late abortions at our institution were chosen. They were divided into groups based on the treatments used.
Parental separation following preterm delivery in Canada: a population-based cohort study.
BMJ Paediatr Open
December 2024
Medicine, University of Manitoba Faculty of Medicine, Winnipeg, Manitoba, Canada.
Objective: To examine the association between preterm delivery and parental separation and identify associated risk factors.
Methods: All opposite sex, married or common-law parents whose relationship status was available at index delivery and for the next 5 years were eligible in this retrospective population-based cohort study in Manitoba, Canada. Parents of children born preterm were matched 1:5 to parents of children born full-term.
Prediction of neonatal survival among Pacific Islander preterm births in the US.
PLoS One
December 2024
Department of Chronic Disease Epidemiology, Yale University School of Public Health, New Haven, Connecticut, United States of America.
Objective: Predicting neonatal survival is essential for targeting interventions to reduce neonatal mortality. Pacific Islanders have been underrepresented in existing prediction tools and have unique, maternal obesity-related risk factors for both preterm birth and neonatal mortality. Using neonatal sex, birth weight, and gestational age, we developed a graphical tool for neonatal survival among Pacific Islander singletons in the United States.

The background of Helicobacter pylori (H. pylori) infection is complex, and its influence on adverse pregnancy outcomes is inconsistently reported. We performed a multi-institutional, retrospective analysis using de-identified electronic health records from the TriNetX Research Network to compare various pregnancy outcomes in women with and those without H.

A defect in the fusion of Müllerian ducts results in the uterine malformation of the bicornuate uterus. The bicornuate uterus is an uncommon condition, and it is associated with adverse early pregnancy and antenatal events, such as recurrent miscarriages, preterm labor, and delivery. The bicornuate uterus has two symmetric uterine cavities that are fused caudally and have some degree of communication between the two cavities, usually at the uterine isthmus.
