Assessment of aortic dissection remodeling with patient-specific fluid-structure interaction models.

Aortic dissection leads to late complications due to chronic degeneration and dilatation of the false lumen. However, the interaction between hemodynamics and microstructural remodeling driving long-term changes is not fully understood. This study examines the progression of a patient's aortic dissection, tracked from pre-dissection to the chronic phase using computed tomography angiography.

Early three-dimensional growth in uncomplicated type B aortic dissection is associated with long-term outcomes.

Objective: Late adverse events (LAEs) are common among initially uncomplicated type B aortic dissection (uTBAD); however, identifying those patients at highest risk of LAEs remains a significant challenge. Early false lumen (FL) growth has been suggested to increase risk, but confident determination of growth is often hampered by error in two-dimensional clinical measurements. Semi-automated three-dimensional (3D) mapping of aortic growth, such as by vascular deformation mapping (VDM), can potentially overcome this limitation using computed tomography angiograms (CTA).

Tumor board simulation improves interdisciplinary decision-making in medical students.

Introduction: Training of interdisciplinary clinical reasoning and decision-making skills, essential in daily clinical practice in oncological specialties, are still underrepresented in medical education. Therefore, at LMU University Hospital Munich, we implemented a didactically modified tumor board simulation with experts from five different disciplines (medical oncology, pathology, radiation oncology, radiology, and surgery) presenting patient cases into a one-week course on the basic principles of oncology. In this survey, we examined the self-assessed impact of our course on the interdisciplinary decision-making skills of medical students.

Long-term residence and efficacy of adenovirus-mimetic nanoparticles in renal target tissue.

A major shortcoming in the treatment of mesangial cell-associated diseases such as IgA nephropathy, diabetic nephropathy, or lupus nephritis, which frequently progress to end-stage renal disease, is poor drug availability in the glomerular mesangium. Drug delivery active targeting of nanoparticles, using ligands attached to the particle surface for target cell recognition to increase the biodistribution to the mesangium, is a promising strategy to overcome this hurdle. However, although several glomerular tissue targeting approaches have been described, so far no study has demonstrated the particles' ability to deliver sufficient drug amounts combined with an appropriate nanoparticle target retention time to trigger relevant biological effects in the mesangium.
