A systematic review of disparities in the medical management of atherosclerotic cardiovascular disease in females.

Atherosclerotic cardiovascular disease (ASCVD) is the leading cause of death in the United States and worldwide. Medical management of known modifiable risk factors, such as dyslipidemia, hypertension, and diabetes, is a key aspect to its treatment. Unfortunately, there are substantial sex-based differences in the treatment of ASCVD that result in poor medical management and worse clinical outcomes.

Maintenance and Salvage of Hemodialysis Access.

Many end-stage kidney failure patients require hemodialysis as a life-sustaining treatment. Hemodialysis access via arteriovenous fistula or graft creation is preferred over long-term dialysis catheters, but intervention to maintain patency and prevent access failure is common. Endovascular and open surgical techniques are both utilized to address the underlying etiology of failure.

Angle of impact determination from bullet holes in a metal surface.

Using the best-fit ellipse method, single bullet impacts in thin sheet metal were assessed to investigate the accuracy of impact angle estimation. When a bullet passes through a metal panel, the yielding nature of metal causes changes to the metal surface and the resultant hole. This deformation of the metal complicates the assessment of single impacts using the ellipse method.

Resolving Reflection and Resolution in 3D Imaging of Fresh Bone.

Structured light scanning is a noninvasive, accurate, and cost-effective 3D imaging technique, but due to reflection issues is yet to be utilized for tool mark analysis on fresh bone. During imaging, reflection from shiny surfaces, such as greasy bone, disrupts image formation. This study tested the David SLS-1 scanner's ability to image saw marks and explored six strategies to reduce reflection by [1] dulling the surface or [2] altering the projected light.
