Background: Desmotomy of the accessory ligament of the superficial digital flexor tendon (AL-SDFT) has been described for the treatment of superficial digital flexor tendon (SDFT) tendinopathy in Thoroughbred and Standardbred racehorses, and in event horses. To our knowledge, the outcome of this procedure has not been described in a population of warmblood horses.

Objective: To report on the outcome of treatment of SDFT tendinopathy in warmblood horses using tenoscopic desmotomy of the main part of the AL-SDFT.

High-resolution X-ray imaging of noncrystalline objects is often achieved through the approach of scanning coherent diffractive imaging known as ptychography. The imaging resolution is usually limited by the scattering properties of the sample, where weak diffraction signals at the highest scattering angles compete with parasitic scattering. Here, we demonstrate that X-ray multilayer Laue lenses with a high numerical aperture (NA) can be used to create a strong reference beam that holographically boosts weak scattering from the sample over a large range of scattering angles, enabling high-resolution imaging that is tolerant of such background.

We report on recent developments that enable megahertz hard X-ray phase contrast imaging (MHz XPCI) experiments at the Single Particles, Clusters, and Biomolecules and Serial Femtosecond Crystallography (SPB/SFX) instrument of the European XFEL facility (EuXFEL). We describe the technical implementation of the key components, including an MHz fast camera and a modular indirect X-ray microscope system based on fast scintillators coupled through a high-resolution optical microscope, which enable full-field X-ray microscopy with phase contrast of fast and irreversible phenomena. The image quality for MHz XPCI data showed significant improvement compared with a pilot demonstration of the technique using parallel beam illumination, which also allows access to up to 24 keV photon energies at the SPB/SFX instrument of the EuXFEL.

Article Synopsis
  • Functional neurological disorder (FND) involves a range of conditions that affect neurological functions without any underlying structural changes in the brain or nervous system.!* -
  • Diagnosis and management of FND share similarities between children and adults, but identifying it in adults can be more complicated due to various factors.!* -
  • The article primarily discusses the unique challenges and considerations related to diagnosing and managing FND specifically in adults.!*

Functional neurological disorder (FND) is common among children and adolescents, results in significant impairments in quality of life, and places a substantial burden on healthcare systems. Despite this, there is minimal literature to guide prescribing for this population. The purpose of this article is to provide common sense prescribing recommendations for providers who treat pediatric FND.
