The nature and nurture of primary and secondary callous–unemotional traits: evidence from two independent twin samples

Journal of Child Psychology and Psychiatry, Volume 67, Issue 6, Page 988-997, June 2026.
Background Callous–unemotional (CU) traits identify youth with more severe and chronic trajectories of conduct problems. However, the etiology of CU traits may be heterogeneous, undermining the search for effective treatments.

The risk of monozygotic twins after assisted reproductive technology: A systematic review and meta-analysis

, 2009
Background: It is estimated that there is at least a 2-fold rise in the incidence of monozygotic twinning after assisted reproductive technology compared with natural conception. This can result in adverse pregnancy outcomes. Methods: We searched MEDLINE,

Journal of Sleep Research, Volume 35, Issue 3, June 2026.
ABSTRACT Sleep is essential for human functioning, but little attention has been paid to the interplay between sleep and maladaptive personality traits. We examined genetic and environmental associations between sleep and four maladaptive domains (MDs)—Negative Affectivity, Detachment, Disinhibition, and Psychoticism—within the framework of the DSM‐5 ...

Focal cerebral ischemia and mitral valve prolapse in monozygotic twins

, 2008
Mitral valve prolapse (MVP) is a common frequently inherited cardiac valvular disorder. Ischemic cerebrovascular disease (ICVD) is an apparent complication of MVP. We report the concordance of MVP and ICVD in a pair of monozygotic twins.
