Pregnancy is characterized by a complex interplay of inflammatory events regulated by both the innate and acquired immune systems. Similarly, parturition can be viewed as the activation of "pro-labour" inflammatory pathways, which drive cervical ripening and myometrial activation. Premature activation of these pathways, for example, by infection, can lead to preterm labour and birth. Nuclear factor κβ is a key modulator of these pathways and functions by regulating the expression of prostaglandins, chemokines and pro-inflammatory cytokines involved in both term and preterm labour. Future design of therapeutics that target key mediators of inflammation and immune activation would therefore be a rational approach for preventing preterm labour and immune-mediated neonatal brain damage.

Impact of endometrial thickness and its combined effect with maternal age on singleton adverse neonatal outcomes in frozen-thawed embryo transfer cycles.
Front Endocrinol (Lausanne)
January 2025
Center for Reproductive Medicine and Obstetrics and Gynecology, Nanjing Drum Tower Hospital, Affiliated Hospital of Medical School, Nanjing University, Nanjing, China.
Background: Thin endometrial thickness (EMT) and advanced age are both common risk factors for adverse neonatal outcomes (ANOs). However, studies evaluating the impact of EMT and combined effect of EMT and age on ANOs remain scarce with conflicts.
Method: A retrospective cohort study was conducted on 7,715 singleton deliveries from frozen embryo transfer (FET) cycles between 2017 and 2021.
Preterm Labor and Hypertensive Disorders in Adolescent Pregnancies With Diabetes Between 2006 and 2019.
Pediatr Diabetes
January 2025
Division of General Internal Medicine and Health Services Research, Department of Medicine, David Geffen School of Medicine, University of California, Los Angeles, California, USA.
Objective: We sought to evaluate the risk of preterm labor and hypertensive disorders in adolescent pregnancies with and without diabetes.
Methods: We evaluated 1,843,139 adolescents (≤20 years old) with labor and delivery admissions in the national Kids' Inpatient Database (KID) in years 2006, 2009, 2012, 2016, and 2019. International classification of disease codes was used to identify diabetes and medical factors affecting pregnancy.
Association between interpregnancy interval and adverse perinatal outcomes according to maternal age in the context of China's two-child policy.
BMC Pregnancy Childbirth
January 2025
Department of Health Care, School of Medicine, Chengdu Women's and Children's Central Hospital, University of Electronic Science and Technology of China, Chengdu, China.
Background: Since the implementation of China's comprehensive two-child policy, the prevalence of long interpregnancy intervals (IPI) and advanced maternal age has increased. However, previous studies in China have mostly focused on the relationship between short IPIs and adverse perinatal outcomes, while neglecting maternal age as a potential confounder.
Methods: We conducted a retrospective cohort study of 23,899 pregnant women who delivered between January 1, 2017 and December 31, 2019 at Chengdu Women's and Children's Central Hospital and West China Second Hospital of Sichuan University.
Adverse birth outcome and associated factors among mothers with antepartum hemorrhage in public hospitals Tigray, northern Ethiopia, 2020.
BMC Pregnancy Childbirth
January 2025
College of Health Science, School of nursing, Mekelle University, Mekelle, Ethiopia.
Background: Adverse birth outcome is a major public health problem in the world and in Ethiopia. Antepartum hemorrhage complicates 3-5% of pregnancies and is a primary cause of perinatal and maternal mortality worldwide. One in five of all preterm babies are born in association with antepartum hemorrhage.
