Objective: We performed closure of the patent ductus arteriosus (PDA) using a hybrid approach with an Amplatzer Duct Occluder.
Methods: Six patients (two males and four females) underwent PDA closure at a mean age of 7.8 months (range 2-24 months) and a mean weight of 6.6 kg (range 4.5-13 kg). The main pulmonary artery (MPA) was exposed via a minimally invasive left parasternal second intercostal space incision. Under transesophageal echocardiography guidance, the PDA occluder was implanted via direct puncture of the MPA.
Results: The procedure was successful in all patients with no residual shunt. There were no hospital deaths, and the postoperative course was uneventful. All patients were discharged on the 3rd to 4th day. There was no residual shunt in any patient on midterm follow-up.
Conclusions: The novel hybrid approach is a safe, minimal invasive procedure. Further experience and longer follow-up of these patients is necessary to conclude whether this technique is applicable to all the patients with a PDA.

Introduction And Importance: Fractures of ossified Achilles tendons are rare and often associated with repetitive jumping and sprinting in young athletes. Although the exact cause of Achilles tendon ossification is unclear, prior trauma and surgery are common contributing factors.
Case Presentation: A 47-year-old male recreational athlete experienced acute pain in his right heel after a football game.
Comprehensive determination of elements ranging from uranium to americium by hybrid measurement of fluorescent and spontaneously emitted characteristic X-rays.

Natural uranium isotopes have extremely long half-lives; therefore, analytical methods based on the number of atoms, such as X-ray fluorescence (XRF) analysis, are suitable for uranium detection. However, XRF measurements cannot be used to detect the major isotopes of americium when present in amounts barely detectable using radiation measurements, owing to their relatively short half-lives. Because of α-decay-induced internal conversion, where orbital electrons are emitted instead of γ-rays, these nuclides emit characteristic X-rays.

Unsupervised domain adaptation (UDA) has shown impressive performance by improving the generalizability of the model to tackle the domain shift problem for cross-modality medical segmentation. However, most of the existing UDA approaches depend on high-quality image translation with diversity constraints to explicitly augment the potential data diversity, which is hard to ensure semantic consistency and capture domain-invariant representation. In this paper, free of image translation and diversity constraints, we propose a novel Style Mixup Enhanced Disentanglement Learning (SMEDL) for UDA medical image segmentation to further improve domain generalization and enhance domain-invariant learning ability.

For MR-Fingerprinting-like approaches, this problem can be addressed with self-navigated retrospective motion correction based on reconstructions in a singular value decomposition (SVD) subspace. However, the SVD promotes high signal intensity in all tissues, which limits the contrast between tissue types and ultimately reduces the accuracy of registration.
