Early Supraspinal Influences on Human Embryonic Posture.

Knowledge of embryonic body posture as a reflection of neurodevelopment is limited. Here, we investigate embryonic body posture, preference, symmetry, and lateralization during periods of rest using virtual reality (VR) and four-dimensional (4D) ultrasound techniques to enhance our knowledge of neurodevelopment. It is hypothesized that lateralization and asymmetry in embryonic posture are absent.

Evaluation of embryonic posture using four-dimensional ultrasound and virtual reality.

Aim: To assess the possibility of embryonic posture evaluation (=feasibility, reproducibility, variation) at rest at 9 weeks' (+0-6 days) gestational age (GA) using four-dimensional ultrasound and virtual reality (VR) techniques. Moreover, it is hypothesized that embryonic posture shows variation at the same time point in an uneventful pregnancy.

Methods: In this explorative prospective cohort study, 23 pregnant women were recruited from the Rotterdam periconceptional cohort.

Current practice of preconception care by primary caregivers in the Netherlands.

Objectives: Over the past decade the value of preconception care (PCC) consultations has been acknowledged. Investments have been made to promote delivery and uptake of PCC consultations in the Dutch primary care setting. We assessed current activities, perceptions and prerequisites for delivery of PCC in primary care.
