AI Article Synopsis
- Many studies have linked chronic hepatitis B virus (CHB) infection to an increased risk of preterm labor, but results have been inconsistent.
- A meta-analysis was conducted by reviewing several observational studies to better understand the relationship between CHB infection and preterm labor.
- The analysis, which included data from 6781 women, concluded that there is no significant association between CHB infection and the risk of preterm labor (odds ratio of 1.12).
Article Abstract
Many epidemiological studies have found a positive association between chronic hepatitis B virus (CHB) infection and the risk of preterm labor, but the magnitude of this association varies and independent studies have reported conflicting findings. We performed a meta-analysis to ascertain the relationship between CHB infection and preterm labor. The PubMed and Embase databases were searched up to May 1st, 2014, for relevant observational studies on an association between CHB infection and the risk of preterm labor. Data were extracted and analyzed independently by two authors. The meta-analysis was performed using Stata version 10.0 software. Six observational case-control studies and 4 cohort studies, involving 6781 women with preterm labor, were identified. Based on a random-effects meta-analysis, no association between CHB infection and preterm labor was identified (odds ratio=1.12, 95% confidence interval CI, 0.94-1.33). Our meta-analysis suggested that CHB infection is not associated with an increased risk of preterm labor.

Importance: Current evidence of the association between prenatal exposure to glucocorticoids and long-term mental disorders is scarce and has limitations.
Objective: To investigate the association between prenatal exposure to systemic glucocorticoids and mental disorders in offspring at the age of 15 years, comparing exposed vs unexposed offspring born to mothers with the same underlying disease (risk of preterm delivery and autoimmune or inflammatory disorders).
Design, Setting, And Participants: This nationwide population-based cohort study used data from registries in Denmark with follow-up until December 31, 2018.
The Predictive Role of Maternal Serum Amyloid A in Preterm Birth: An Observational Study in Romania.

Background: Despite improvements in pregnancy care, preterm birth remains a major cause of neonatal morbidity and mortality worldwide, particularly in developing countries. Maternal inflammation has been recognized as a factor that may induce preterm birth, with various inflammatory markers associated with its pathogenesis. The aim of this study is to evaluate the value of maternal serum amyloid A(SAA) level as a predictive marker for preterm delivery in a Romanian cohort.

The tolerance and dynamic regulation of the maternal immune system during pregnancy are pivotal for ensuring fetal health. Immune cell subsets play a complex and crucial role in this process, closely linked to the neonatal health status. Despite recognizing the significance of dysregulation in the quantity and activity of immune cells in neonatal disease occurrence, their specific roles remain elusive, resulting in a dearth of clinically viable interventions for immune-mediated neonatal diseases.

Background: Mother's own milk (MOM) is important as the first nutrition for preterm infants, but mothers often struggle to initiate milk production right after preterm birth. If antenatal breastmilk expression (aBME) does not induce preterm labor when performed before term age, it could promote nutrition with MOM right after preterm birth. In this pilot study, we aimed to investigate whether aBME induces preterm labor among healthy nulliparous women from week 34 of pregnancy, to examine if aBME promotes the availability of MOM right after birth and affects breastfeeding outcomes.

Background: Preterm birth (PTB) is a leading cause of neonatal mortality, particularly in sub-Saharan Africa where 40% of global neonatal deaths occur. We identified and combined demographic, clinical, and psychosocial correlates of PTB among Kenyan women to develop a risk score.
Methods: We used data from a prospective study enrolling HIV-negative women from 20 antenatal clinics in Western Kenya (NCT03070600).
