The Patient, the Provider, and the TikTok Creator: Qualitative Analysis of the Content and Quality of Videos on Prenatal Genetic Screening

Journal of Midwifery &Women's Health, EarlyView.
Introduction Although providers may view the use of the noninvasive prenatal testing (NIPT) screen as an opportunity for patients to learn more about potential chromosomal variants of a fetus, research suggests that patients may view the genetic screening test primarily as an opportunity to learn about their fetus's sex chromosomes and may not ...

High‐elevation adaptation and gestational hypoxia jointly shape vascular development in a rodent placenta

The Journal of Physiology, EarlyView.
Abstract figure legend We investigated how environmental hypoxia and genetic adaptation to high altitudes jointly impact the development of the placental exchange surface in ways that might protect fetal growth potential. We used wild‐derived, lab‐born North American deer mice (Peromyscus maniculatus) from low‐elevation and high‐elevation environments (

Human placental exposure to pollutant nanoparticles: uptake, translocation and functional impact

The Journal of Physiology, EarlyView.
Abstract figure legend Prenatal exposure to pollutant nanoparticles has been increasingly investigated due to concerns about their potential effects on placental function and pregnancy outcomes. Maternal inhalation of pollutant nanoparticles can result in a pro‐inflammatory response; particles can also translocate across the alveolus epithelial barrier

Physiological and anatomical determinants of placental drug transfer

The Journal of Physiology, EarlyView.
Abstract figure legend Fetal exposure to pharmaceuticals and their subsequent clearance back to the maternal circulation are governed by placental transfer. Passive diffusion down a maternal‐to‐fetal concentration gradient is the primary route of fetal drug exposure, with specific compounds undergoing transporter‐mediated transfer.

A primary cell‐based fluidic co‐culture model to investigate drug transport across the human placenta

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic overview of a flow‐driven in vitro model of the human placental barrier designed to study transport processes during pregnancy. The model recreates key features of the maternal–fetal interface, enabling the investigation of how nutrients and therapeutic compounds cross the placental barrier under physiologically ...

Maternal nutrition as a key determinant of placental and developing blood–brain barrier xenobiotic protective functions

The Journal of Physiology, EarlyView.
Abstract figure legend Suboptimal maternal nutrition alters placental and developing blood–brain barrier (BBB) protective function and is associated with increased fetal brain vulnerability. In the placenta, nutritional adversity may reduce the exchange surface area and promote meta‐inflammation, compromising barrier efficiency in a model‐ and context ...

A Case of a Chronic Ectopic Pregnancy in a Patient With Negative Serum β‐HCG

Clinical Case Reports, Volume 14, Issue 7, July 2026.
ABSTRACT Chronic ectopic pregnancy should be considered in women with adnexal masses and persistent abdominal pain, even when serum β‐hCG is negative, to prevent delayed diagnosis. This article reports a case of ectopic pregnancy with negative serum β‐hCG levels nearly 3 months after curettage.

Fetal karyotyping in adolescent pregnancies: a population-based cohort study on outcomes of invasive prenatal testing

Frontiers in Genetics
BackgroundAdolescent pregnancies present unique challenges in prenatal diagnostics, yet data on the prevalence and types of chromosomal abnormalities in this population remain limited.ObjectiveThis study aimed to assess the prevalence and spectrum of ...

Parental behaviors supporting child development in mothers of children with sex chromosome trisomies

Infant Mental Health Journal: Infancy and Early Childhood, Volume 47, Issue 4, July 2026.
Abstract Sex chromosome trisomies (SCTs) are genetic conditions caused by the presence of an additional sex chromosome. While recent studies have focused on analyzing the early competencies of children with SCTs, relatively few have investigated aspects of parent‐child interaction.

First Revision of the Guidelines for the Diagnosis and Management of Remethylation Disorders

Journal of Inherited Metabolic Disease, Volume 49, Issue 4, July 2026.
ABSTRACT This guideline summarizes diagnostic and therapeutic approaches based on a systematic literature review and evidence evaluation using the GRADE methodology. Given the limited high‐quality data, expert consensus was additionally obtained through a modified Delphi process.
