Do the early social environment and persistent peripartum depressive symptoms shape toddlers' expressive language?

open access: yesJCPP Advances, EarlyView.
Abstract Background Extensive research suggests that peripartum depression is a risk factor for children's early language development. Yet, previous research on this association shows mixed results, often lacking information on the persistence of depression and the social context.

Genetic and environmental links between self-reports and parent-reports of child personality [PDF]

open access: yes, 2018
Personality ratings have been consistently found to be reliable and moderately heritable, but interrater agreement between self- and other-report of personality are low-to-moderate, particularly in childhood samples. The current study aims to examine the

Intergenerational transmission of attachment: The role of intelligence

open access: yesJCPP Advances, EarlyView.
Attachment and cognitive development are associated, but the direction of the association is unclear. Recently, Del Giudice and Haltigan have argued that attachment in childhood and attachment representations in adulthood are influenced by the cognitive capabilities of the individual, which might make the intergenerational transmission of attachment ...

Isolated anorectal malformation with rectoperineal fistula in monozygotic twins

open access: yesJournal of Pediatric Surgery Case Reports, 2019
Incidence of anorectal malformation (ARM) is reportedly 1 in approximately 2500–5000 live births. While its etiology remains elusive, most evidence indicates genetic factors to be the major cause.

Increased expression and altered methylation of HERVWE1 in the human placentas of smaller fetuses from monozygotic, dichorionic, discordant twins. [PDF]

open access: yesPLoS ONE, 2012
BACKGROUND: The human endogenous retroviral family W, Env(C7), member 1 gene (HERVWE1) is thought to participate in trophoblast cell fusion, and its expression is diminished in the placentas of singleton intrauterine growth-retarded pregnancies. However,

Why do spatial abilities predict mathematical performance? [PDF]

open access: yes, 2014
Spatial ability predicts performance in mathematics and eventual expertise in science, technology and engineering. Spatial skills have also been shown to rely on neuronal networks partially shared with mathematics.

Genetic and environmental influences on sleep quality, ability to settle, and crying duration in 2‐ and 5‐month‐old infants: A longitudinal twin study

open access: yesJCPP Advances, EarlyView.
This study found that genetic factors largely influence crying duration and settle ability in infancy, while shared environmental factors primarily affect the number of night wakeups. Etiological influences tended to change from 2 to 5 months, reflecting a highly plastic period in infant brain development and in child‐environment interactions. Abstract

Outcome of two pairs of monozygotic twins with pleuropulmonary blastoma: case report

open access: yesItalian Journal of Pediatrics, 2020
Background Pleuropulmonary blastomas (PPB) are rare aggressive paediatric lung malignancies and are among the most common DICER1-related disorders: it is estimated that 75–80% of children with a PPB have the DICER1 mutation.

Genome-Wide Analysis of DNA Methylation Differences in Muscle and Fat from Monozygotic Twins Discordant for Type 2 Diabetes

open access: yesPLoS ONE, 2012
Background Monozygotic twins discordant for type 2 diabetes constitute an ideal model to study environmental contributions to type 2 diabetic traits. We aimed to examine whether global DNA methylation differences exist in major glucose metabolic tissues ...

Trigger Twins: 2 Cases of Ipsilateral Twin Trigger Digit and a Review of Published Literature

open access: yesCase Reports in Orthopedics, 2019
Background. The aetiology of trigger digits has been debated since Notta first described them in 1850. Aetiology has been segregated for adult and paediatric presentations. While an adult trigger digit is most likely an acquired inflammatory process, the
