Preterm birth (PTB) is a global problem with a high incidence in the developing world. Relaxin (RLN) has classically been associated with parturition, but its role(s) in the human have been difficult to determine. For the first time, we bring together the systemic (ovarian) and autocrine/paracrine (intrauterine) sources of RLN, in an attempt to understand how RLN contributes to PTB in women.

Objectives: This study aimed to estimate the prevalence of homelessness shortly before or during pregnancy and describe differences in maternal characteristics and adverse birth outcomes between people reporting homelessness and not reporting homelessness.
Methods: We used 2016-2020 Pregnancy Risk Assessment Monitoring System (PRAMS) data from 31 sites to estimate the prevalence of self-reported homelessness during the 12 months before giving birth. We used logistic regression models to evaluate the association between homelessness and adverse birth outcomes, specifically small for gestational age (SGA), low birth weight (LBW), and preterm birth (PTB).

Objective: To investigate whether gestational diabetes mellitus (GDM) mediates the association between assisted reproductive technology (ART) and preterm birth (PTB), and to examine the interaction and joint effects of ART and GDM on PTB.
Methods: This retrospective cohort study utilized data from 20,721 mothers with singleton live births at Sichuan Jinxin Xinan Women and Children's Hospital from January 2020 to December 2023. The exposures were ART and GDM, and the outcome was PTB.

Objectives: This study investigates the relationship between serum homocysteine, blood lipids, and perinatal outcomes in patients with diet-controlled gestational diabetes mellitus (GDM) and those with normal glucose tolerance (NGT).
Material And Methods: A prospective cohort of 150 diet-controlled GDM patients and 150 pregnant women with NGT, all delivering at our hospital, were selected based on predefined criteria. Data on demographics, physical parameters, and perinatal outcomes were compiled.

Aim: Uncontrolled chronic inflammatory diseases (CIDs) before, during, and after pregnancy, as well as some CID medications, can increase the risk of impaired fertility in addition to adverse maternal/pregnancy outcomes in women of childbearing age. We report pregnancy outcomes from prospectively reported pregnancies in Japanese women treated with certolizumab pegol (CZP).
Methods: Data from July 2001 to November 2020 on CZP-exposed pregnancies from the CZP Pharmacovigilance safety database were reviewed.
Background And Aims: Neonatal sepsis is a major cause of neonatal mortality worldwide. It remains a detrimental bottleneck to the WHO goal of eradicating preventable deaths for children below 5 years of age by 2030. Though the risk factors for adverse clinical outcomes for neonatal sepsis have been widely studied there is no universal consensus.
