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.

Twin pregnancies and the limits of the energetics of gestation and growth hypothesis

The Anatomical Record, EarlyView.
Abstract The “Energetics of Gestation and Growth” (EGG) hypothesis proposes that human birth timing and the associated secondary altriciality of human newborns is determined by limits in maternal metabolic capacity. According to this model, labor is triggered when the increasing fetal energy requirements exceed the expectant mother's maximum sustained ...

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 ...

Poor attention rather than hyperactivity/impulsivity predicts academic achievement in very preterm and full-term adolescents [PDF]

, 2013
Background: Very preterm (VP) children are at particular risk for attention deficit/hyperactivity disorder (ADHD) of the inattentive subtype. It is unknown whether the neurodevelopmental pathways to academic underachievement are the same as in the ...

A biomimetic ducted nipple reveals gestational age‐dependent deficits in suction generation in a neonatal pig model

The Anatomical Record, EarlyView.
Abstract All infant mammals must suckle in order to effectively acquire milk from a nipple. Yet, not all infants are able to do so. Preterm infants in particular face significant feeding challenges, often failing to establish successful breastfeeding due to complex neurophysiologic challenges.

Characterizing Autism Phenotype Onset in the Electronic Health Records to Enable Age‐Specific Screening

Autism Research, EarlyView.
ABSTRACT Autism exhibits substantial phenotypic heterogeneity, yet age‐dependent variation in phenotypic profiles and onset timing remains poorly understood. We aimed to characterize stage‐specific phenotypes and temporal onset patterns of autism using longitudinal electronic health records (EHRs).
