Design: Retrospective observational study utilizing data from the Department of Defense and Veterans Health Administration clinical and administrative data repositories derived from medical records, claims, and enrollment data.
Setting: Military Health System, Veterans Health System, and civilian healthcare facilities.
Modeling bladder mechanics with 4D reconstruction of murine ex vivo bladder filling.
Biomech Model Mechanobiol
December 2024
This study presents a novel methodology for high-resolution 3D bladder modeling during filling, developed by leveraging improved imaging and computational techniques. Using murine bladder filling data, the methodology generates accurate 3D geometries across time, enabling in-depth mechanical analysis. Comparison with a traditional spherical model revealed similar stress trends, but the 3D model permitted nuanced quantifications, such as localized surface curvature and stress analysis.

- This study aimed to confirm the reliability of measuring choriocapillaris flow deficit (CCFD) within a specific macular grid and to track these measurements over time.
- Researchers utilized advanced imaging technology to gather data, excluding certain areas in the scans to accurately calculate CCFD percentages in both normal eyes and those with eye conditions.
- The findings showed that the methodology is effective for monitoring changes in CCFD, particularly in cases where drusen (eye abnormalities) resolved, demonstrating the practicality of the grid strategy for longitudinal studies.
The study of land subsidence has recently been expanded due to its increased occurrence and magnitude worldwide. This paper develops and applies an optimal control model of groundwater extractions under conditions of land subsidence. We include, in a traditional groundwater management model, two types of negative externalities associated with land subsidence: damage to infrastructure and to economic activities, and the loss of aquifer storage capacity.

One of the various presentations is compartment syndrome secondary to a spontaneous hematoma.
Case Presentation: A 95-year-old woman arrived at the emergency department with a one-week history of progressive pain in the right leg, without a previous history of trauma.
