The Mitochondria‐Targeted Peptide Therapeutic Elamipretide Improves Cardiac and Skeletal Muscle Function During Aging Without Detectable Changes in Tissue Epigenetic or Transcriptomic Age

open access: yesAging Cell, EarlyView.
The effects of the mitochondria‐targeted peptide therapeutic elamipretide on age‐related muscle function were compared with its effects on molecular biomarkers of aging. It was found that elamipretide treatment partially reverses age‐related cardiac dysfunction and skeletal muscle weakness in mice without significantly affecting muscle epigenetic or ...

Muscle Mitochondrial Respiration and Cardiorespiratory Fitness Contribute to Slower Walking Speed of Older Individuals Who Identify as Black

open access: yesAging Cell, EarlyView.
While the etiology of race differences in mobility is multifactorial, our data indicate that muscle mitochondrial respiration and cardiorespiratory fitness may contribute to the slower walking speed of individuals who identify as Black compared to White.

Aging‐Associated Vacuolation of Multi‐Ciliated Cells in the Distal Mouse Oviduct Reflects Unique Cell Identity and Luminal Microenvironment

open access: yesAging Cell, EarlyView.
Multi‐ciliated cells in the infundibulum and ampulla (INF/AMP) epithelium are vacuolated in aging. Unique cellular susceptibility of the INF/AMP epithelial population and aging‐associated decline in ovarian artery circulation, which supports the ovary and INF/AMP, contribute to this region‐specific vacuolation phenotype, as a consequence of a mildly ...

Ecological Realism Accelerates Epigenetic Aging in Mice

open access: yesAging Cell, EarlyView.
Living environment shapes mammalian aging, but laboratory conditions lack the ecological realism of natural social, physical, and microbial environments. Comparing traditionally laboratory‐reared and “re‐wilded” C57BL/6J mice, we reveal accelerated, genomic region‐dependent epigenetic aging in the liver under naturalistic field conditions, highlighting

Epidemiology of diagnostic errors in pediatric emergency departments using electronic triggers

open access: yesAcademic Emergency Medicine, Volume 32, Issue 3, Page 226-245, March 2025.
Abstract Objectives We applied three electronic triggers to study frequency and contributory factors of missed opportunities for improving diagnosis (MOIDs) in pediatric emergency departments (EDs): return visits within 10 days resulting in admission (Trigger 1), care escalation within 24 h of ED presentation (Trigger 2), and death within 24 h of ED ...
