Transcriptomic changes in retinal ganglion cell types associated with the disruption of cholinergic retinal waves.

In the early stages of retinal development, a form of correlated activity known as retinal waves causes periodic depolarizations of immature retinal ganglion cells (RGCs). Retinal waves are crucial for refining visual maps in the brain's retinofugal targets and for the development of retinal circuits underlying feature detection, such as direction selectivity. Yet, how waves alter gene expression in immature RGCs is poorly understood, particularly at the level of the many distinct types of RGCs that underlie the retina's ability to encode diverse visual features.

Associations between subclinical thyroid dysfunction and cardiovascular risk factors according to age and sex.

Context: Subclinical thyroid dysfunction (ScTD) comprising subclinical hypothyroidism (SHypo) and subclinical hyperthyroidism (SHyper) has been associated with increased risk for cardiovascular events.

Objective: To assess associations between ScTD and cardiovascular risk factors (cvRFs) according to age and sex.

Design And Setting: Pooled individual participant data analysis of large prospective cohort studies from the Thyroid Studies Collaboration.

Visualizing synaptic pruning in the mammalian brain.

Patterns of spontaneous neuronal activity instruct the refinement of developing brain circuits.

Protocolized abuse screening to decrease provider bias and increase capture of potential events.

Background: Early identification of child abuse is critical to prevent death and disability. Studies suggest implicit bias of providers may lead to overrepresentation of minority and impoverished children in child abuse reporting. At our institution, universal screening for sexual and physical abuse for all children under 18 years of age was implemented in 2016.
