Computer modeling tools to understand the causes of preterm birth

Area of Science:

• Biomedical Engineering
• Maternal-Fetal Medicine
• Computational Mechanics

Background:

• The mechanical integrity of soft tissues supporting the fetus is crucial for healthy pregnancy and labor onset.
• Current understanding of mechanical loading on the uterus, cervix, and fetal membranes during pregnancy is limited.
• Tissue over-stretch is hypothesized to contribute to preterm birth through increased contractility, remodeling, and membrane rupture.

Purpose of the Study:

• To review engineering analysis tools for evaluating and predicting mechanical loads on key pregnancy tissues.
• To explore the use of computational biomechanics and finite element analysis in studying preterm birth.
• To identify potential engineering variables for signaling abnormal pregnancies and developing predictive diagnostic tools.

Main Methods:

• Review of engineering analysis tools, specifically computational biomechanics and finite element analysis.
• Discussion of defining engineering terms and identifying relevant engineering variables.
• Exploration of model validation processes and limitations.

Main Results:

• Engineering analysis tools offer potential for evaluating mechanical loads during pregnancy.
• Computational models can aid in understanding preterm birth mechanisms.
• Identification of engineering variables may lead to predictive diagnostic tools for gestational outcomes.

Conclusions:

• Computational biomechanics and finite element analysis provide promising avenues for preterm birth research.
• Translational ability of computational models can improve clinical patient management.
• Interdisciplinary approaches, borrowing from parallel engineering fields, can advance patient care and work towards eliminating preterm birth.
