Timely initiation of antenatal care in adolescent victims of sexual violence: implications for legal abortion in Brazil.

Cien Saude Colet

January 2025

Centro Internacional de Equidade em Saúde, Programa de Pós-Graduação em Epidemiologia, Universidade Federal de Pelotas. R. Marechal Deodoro 1160, Centro. 96020-220 Pelotas RS Brasil.

We investigated the timely initiation of antenatal care among Brazilian adolescents to support the national discussion on the gestational age limit for legal abortion. Using data from the Live Births Information System (SINASC) 2020-2022, we correlated the timely antenatal care (first quarter of pregnancy) with the adolescent's age, region, ethnicity/skin color, and schooling level; 11,607 annual births result from vulnerable rape. The timely initiation of antenatal care was 70.

Objectives: Juvenile idiopathic arthritis (JIA) originates from a complex interplay between genetic and environmental factors. We investigated the association between seafood intake and dietary contaminant exposure during pregnancy and JIA risk, to identify sex differences and gene-environment interactions.

Methods: We used the Norwegian Mother, Father, and Child Cohort Study (MoBa), a population-based prospective pregnancy cohort (1999-2008).

Prenatal stress has a well-established link to negative biobehavioral outcomes in young children, particularly for girls, but the specific timing during gestation of these associations remains unknown. In the current study, we examined differential effects of timing of prenatal stress on two infant biobehavioral outcomes [i.e.

Placental PFAS concentrations are associated with perturbations of placental DNA methylation.

Environ Pollut

January 2025

Department of Pediatrics, University of Arkansas for Medical Sciences, Little Rock, AR; Arkansas Children's Nutrition Center, Little Rock, AR.

The placenta is crucial for fetal development, is affected by PFAS toxicity, and evidence is accumulating that gestational PFAS perturb the epigenetic activity of the placenta. Gestational PFAS exposure can adversely affect offspring, yet individual and cumulative impacts of PFAS on the placental epigenome remain underexplored. Here, we conducted an epigenome-wide association study (EWAS) to examine the relationships between placental PFAS levels and DNA methylation in a cohort of mother-infant dyads in Arkansas (N=151).

: We aimed to identify neonatal circulating metabolic alterations associated with maternal gestational diabetes mellitus (GDM) and to explore whether these altered metabolites could mediate the association of GDM with offspring neurodevelopment. Additionally, we investigated whether neonatal circulating metabolites could improve the prediction of offspring neurodevelopmental disorders over traditional risk factors. : The retrospective cohort study enrolled 1228 mother-child dyads in South China.
