Insights
Intrauterine growth restriction (IUGR) poses significant risks for fetal demise and permanent neurological deficits. This review highlights knowledge gaps and emerging technologies to improve neurodevelopmental outcomes in IUGR.
Area of Science:
- Perinatology
- Neuroscience
- Developmental Biology
Background:
- Intrauterine growth restriction (IUGR) is a major global health concern with significant neurodevelopmental consequences.
- Despite advances, effective therapies to prevent fetal demise and neurological deficits in IUGR remain limited.
Purpose of the Study:
- To identify clinical and translational gaps hindering progress in managing IUGR's neurological sequelae.
- To highlight novel tools, techniques, and technologies for improved understanding and treatment of IUGR.
Main Methods:
- Review of current research and clinical practices related to IUGR.
- Discussion of emerging technologies including advanced monitoring, genomic analysis, and nanoparticle-based drug delivery.
Main Results:
- Gaps exist in understanding IUGR-related inflammation and the need for human post-mortem studies.
- Integrated histology-imaging analyses offer insights into MRI signal specificity.
- Genomic analysis and nanoparticle delivery show potential for risk stratification and targeted treatments.
Conclusions:
- Addressing knowledge gaps in IUGR is crucial for improving neurodevelopmental outcomes.
- Innovative technologies offer promising avenues for better drug design, delivery, and therapeutic interventions in IUGR.
Abstract:
Intrauterine growth restriction (IUGR) is a complex global healthcare issue. Concerted research and clinical efforts have improved our knowledge of the neurodevelopmental sequelae of IUGR which has raised the profile of this complex problem. Nevertheless, there is still a lack of therapies to prevent the substantial rates of fetal demise or the constellation of permanent neurological deficits that arise from IUGR. The purpose of this article is to highlight the clinical and translational gaps in our knowledge that hamper our collective efforts to improve the neurological sequelae of IUGR. Also, we draw attention to cutting-edge tools and techniques that can provide novel insights into this disorder, and technologies that offer the potential for better drug design and delivery. We cover topics including: how we can improve our use of crib-side monitoring options, what we still need to know about inflammation in IUGR, the necessity for more human post-mortem studies, lessons from improved integrated histology-imaging analyses regarding the cell-specific nature of magnetic resonance imaging (MRI) signals, options to improve risk stratification with genomic analysis, and treatments mediated by nanoparticle delivery which are designed to modify specific cell functions.
