Clinical and Molecular Characterization of 46 Patients With Beckwith–Wiedemann Spectrum and Uniparental Disomy of 11p15

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Beckwith–Wiedemann spectrum (BWSp) is an overgrowth disorder characterized by its main clinical features macrosomia, macroglossia, and abdominal wall defects. BWSp is caused by (epi)genetic chromosome 11p15 alterations with approximately 20%–27% of patients exhibiting mosaic paternal uniparental disomy of chromosome 11p15 (pUPD11p15).

Lactobacillus crispatus dominance in the vaginal microbiome reduces the occurrence of spontaneous preterm birth in women with a short cervical length

DST, 2022
Introduction: The majority of pregnant women with a short cervix will deliver at term and, thus, may unnecessarily receive advanced monitoring and treatment.

Over the edge: Empirical evidence for the cliff‐edge model of obstetric selection

The Anatomical Record, EarlyView.
Abstract The cliff‐edge model of obstetric selection maintains that larger neonates and smaller birth canals confer a positive selective advantage until labor becomes obstructed and vaginal delivery is no longer possible, eliciting an abrupt reduction in fitness.

Protein networks are influenced by maternal BMI and differentiate preterm birth types

Communications Medicine
Background Preterm birth remains a leading cause of neonatal morbidity and mortality. It is classified as spontaneous, characterized by the unexpected onset of labor, or medically indicated, resulting from obstetric intervention due to pregnancy ...

Placental circadian lincRNAs and spontaneous preterm birth

Frontiers in Genetics, 2023
Long non-coding RNAs (lncRNAs) have a much higher cell- and/or tissue-specificity compared to mRNAs in most cases, making them excellent candidates for therapeutic applications to reduce off-target effects. Placental long non-coding RNAs have been investigated in the pathogenesis of preeclampsia (often causing preterm birth (PTB)), but less is known ...

Longitudinal measurement of the developing grey matter in preterm subjects using multi-modal MRI. [PDF]

, 2015
Preterm birth is a major public health concern, with the severity and occurrence of adverse outcome increasing with earlier delivery. Being born preterm disrupts a time of rapid brain development: in addition to volumetric growth, the cortex folds ...

The mechanism of labor in nonhuman primates: A look inside

The Anatomical Record, EarlyView.
Abstract While in humans, the flexed position of the fetus and its rotating course down the birth canal are well documented, in other primates the mechanism of labor is unknown. Despite the lack of comparative data, it is commonly assumed that the human obstetric mechanism is unique, and anthropologists have disputed when and why the transition to the ...
