Associations of body size and morphology with cardiometabolic health in children: the contribution of genetic factors

Obesity, Volume 33, Issue 1, Page 125-133, January 2025.
Abstract Objective We analyzed how anthropometric measures predict cardiometabolic health and how genetic and environmental factors contribute to these associations. Methods Data on 8 indicators of cardiometabolic health, 21 anthropometric measures, and 11 anthropometric indices were available for 216 twin pairs of individuals age 3 to 18 years living ...

Congenital diaphragmatic hernia in dizygotic twins [PDF]

, 2015
Congenital diaphragmatic hernia (CDH) is sometimes seen in siblings but is rarely seen in twins, and five survived cases of CDH in monozygotic or dizygotic twins have been reported in the English literature. Here we report a sixth survived case of CDH in

Traces of embryogenesis are the same in monozygotic and dizygotic twins: not compatible with double ovulation

, 2009
Common knowledge of over a century has it that monozygotic and dizygotic twinning events occur by unrelated mechanisms: monozygotic twinning ‘splits’ embryos, producing anomalously re-arranged embryogenic asymmetries; dizygotic twinning begins with ...

The efficacy of expanded non‐invasive prenatal testing (NIPT) in a high‐risk twin pregnancies cohort

Acta Obstetricia et Gynecologica Scandinavica, Volume 103, Issue 12, Page 2426-2432, December 2024.
The efficacy of expanded non‐invasive prenatal testing (NIPT) in twin pregnancies has been less clear. This study presents a relatively optimistic view: expanded NIPT demonstrates high detection rates for common trisomies and moderate DRs for prenatal microdeletion/microduplication syndromes in high‐risk twin pregnancies.

Cell‐free DNA test for fetal chromosomal abnormalities in multiple pregnancies

Acta Obstetricia et Gynecologica Scandinavica, Volume 103, Issue 9, Page 1799-1807, September 2024.
cfDNA testing in twin pregnancies has sufficient screening performance for trisomy 21 but the number of affected cases for other conditions is limited to draw any meaningful conclusion. The use of cfDNA testing in triplet pregnancies and vanishing twins remains an area for further research. Abstract Introduction This study aimed to report the screening

Monochorionic Twinning in Bioengineered Human Embryo Models

Advanced Materials, Volume 36, Issue 25, June 20, 2024.
Using a thermoformed‐based microwell platform culture conditions are identified to create human monochorionic twin blastoids from naïve pluripotent stem cells. Twin blastoids form through division of the pluripotent cell mass and implant with higher efficiency than singleton blastoids in a microfluidic endometrium‐on‐chip adhesion assay.

Non‐invasive cell‐free DNA prenatal screening for trisomy 21 as part of primary screening strategy in twin pregnancy

Ultrasound in Obstetrics &Gynecology, Volume 63, Issue 6, Page 807-814, June 2024.
ABSTRACT Objectives The performance of non‐invasive prenatal screening using cell‐free DNA testing of maternal blood in twin pregnancy is underevaluated, while serum marker‐based strategies yield poor results. This study aimed to assess the performance of non‐invasive prenatal screening for trisomy 21 in twin pregnancy as a first‐tier test.

Amplitude‐integrated electroencephalography showed no differences in cerebral activity between preterm singletons and twins in the first 4 weeks of life

Acta Paediatrica, Volume 113, Issue 6, Page 1356-1363, June 2024.
Abstract Aim Genetic influences on cerebral activity have been described previously, but data are scarce in preterms. We aimed to investigate whether a genetic influence causes amplitude‐integrated electroencephalography (aEEG) signals to differ between singletons and twin preterm newborns. Methods This was a retrospective single‐centre study conducted
