Article Synopsis
- The introduction of antibiotics and surgical treatments has greatly decreased the incidence of infective endarteritis related to patent ductus arteriosus (PDA-IE).
- Despite the reduction in cases, diagnosing and effectively managing PDA-IE in children is still a complex challenge.
- The case study of a 9-year-old girl with PDA-IE provides insight into strategies aimed at reducing complications in young patients.
Article Synopsis
- Magnesium (Mg) alloys, particularly those with gadolinium, are emerging as promising materials for temporary bone implants due to their biocompatibility and mechanical properties, presenting a potential replacement for traditional titanium and stainless-steel implants.
- A study involving rat tibias over various time periods (10, 20, and 32 weeks) used advanced imaging techniques to evaluate the implants' degradation behavior and their integration with bone tissues.
- Results indicate that the Mg-xGd implants not only form a stable degradation layer and support bone remodeling similar to titanium but also do not accumulate harmful levels of Mg or Gd in organs, making them suitable for use in bone repair.
The microstructural architecture of remodeled bone in the peri-implant region of screw implants plays a vital role in the distribution of strain energy and implant stability. We present a study in which screw implants made from titanium, polyetheretherketone and biodegradable magnesium-gadolinium alloys were implanted into rat tibia and subjected to a push-out test four, eight and twelve weeks after implantation. Screws were 4 mm in length and with an M2 thread.

At coherent sources, propagation-based imaging (PBI) techniques are among the most common, as they are easy to implement and produce high-resolution images. Their downside is a low degree of quantitative data due to simplifying assumptions of the sample properties in the reconstruction.
