Background: Maternal shift work is associated with preterm delivery, small-for-gestational-age new-borns, childhood obesity and future behavioural problems. However, the adverse effects on and interactions of maternal shift work with infant neurodevelopment remain uncertain. Therefore, we examined the associations between maternal-shift-work status and infant neurodevelopmental parameters.
Methods: The Taiwan Birth Cohort Study is a nationwide birth cohort study following representatively sampled mother-infant pairs in 2005. The participants' development and exposure conditions were assessed by home interviews with structured questionnaires at 6 and 18 months of age. Propensity scores were calculated with predefined covariates for 1:1 matching. Multivariate conditional logistic regression and the Cox proportional-hazards model were used to examine the association between maternal-shift-work status and infant neurodevelopmental-milestone-achievement status.
Results: In this study, 5637 term singletons were included, with 2098 cases selected in the propensity-score-matched subpopulation. Persistent maternal shift work was associated with increased risks of delays in gross-motor neurodevelopmental milestones [aOR = 1.36, 95% confidence interval (CI) = 1.06-1.76 for walking steadily], fine-motor neurodevelopmental milestones (aOR = 1.39, 95% CI = 1.07-1.80 for scribbling) and social neurodevelopmental milestones (aOR = 1.35, 95% CI = 1.03-1.76 for coming when called upon). Moreover, delayed gross-motor and social development were identified in the propensity-score-matched sub-cohort.
Conclusions: This study shows negative associations between maternal shift work and delayed neurodevelopmental-milestone achievement in the gross-motor, fine-motor and social domains at 18 months. Future research is necessary to elucidate the possible underlying mechanisms and long-term health effects.

This Commentary is part of the Special Issue titled . The Issue examines the Global Financing Facility (GFF) through the lens of nine papers that explore the content and development processes of GFF country documents. While the GFF achieved technical alignment with national reproductive, maternal, newborn, child, and adolescent health priorities, it did not consistently translate into the mobilization of increased domestic resources.

Bivalve mollusks represent a taxonomically and economically significant clade within Mollusca. However, the regulatory mechanisms governing their embryonic development remain poorly characterized. The dwarf surf clam ( ), characterized by a short generation time and high fecundity, has recently gained recognition as an ideal model system for bivalve embryological research.

Advanced maternal age increases the risk of pregnancy complications due, in part, to changes in the uterine environment. Here, we show that uterine aging in mice is associated with a progressive increase in transcriptional variation, accompanied by a notable accumulation of activating histone marks at multiple genomic loci. Importantly, the transcriptional signatures of uterine aging differ substantially from senescence markers associated with organismal aging.

Studies have shown that excessive obstetric interventions such as induced labor and caesarean sections have contributed to the shortening of the length of gestation, leading to a left shift in gestational age (GA) at birth. The aim of this study was to analyze trends in GA and the contribution of associated factors to changes in São Paulo city, Brazil during the period 2012-2019. We conducted an observational time-series study of births in São Paulo using data from Brazil's national live births information system (SINASC).

Objective: Despite advancements in maternity quality care worldwide, mistreatment of women during childbirth persists. Currently, there is a gap of knowledge on the occurrence of disrespect and abuse during childbirth in the World Health Organization (WHO) European region.
Methods: Within the IMAgiNE EURO (Improving Maternal Newborn Care in the WHO European Region During COVID-19 Pandemic) study, women 18 years and older who gave birth in healthcare facilities in the WHO European region, were invited to complete an online validated questionnaire regarding quality of maternity care.
