Non‐Surgical, In‐Stent Membrane Bioelectronics for Long‐Term Intracranial Pressure Monitoring
This image shows a sequence of long‐term intracranial pressure monitoring using non‐surgical, in‐stent membrane bioelectronics. Abstract Traditional intracranial pressure (ICP) monitoring methods, using intraventricular catheters, face significant limitations, including high invasiveness, discrete data, calibration complexities, and drift issues, which

A Localisation-Segmentation Approach for Multi-label Annotation of Lumbar Vertebrae using Deep Nets [PDF]
Multi-class segmentation of vertebrae is a non-trivial task mainly due to the high correlation in the appearance of adjacent vertebrae. Hence, such a task calls for the consideration of both global and local context. Based on this motivation, we propose a two-staged approach that, given a computed tomography dataset of the spine, segments the five ...

ACSGRegNet: A Deep Learning-based Framework for Unsupervised Joint Affine and Diffeomorphic Registration of Lumbar Spine CT via Cross- and Self-Attention Fusion [PDF]
Registration plays an important role in medical image analysis. Deep learning-based methods have been studied for medical image registration, which leverage convolutional neural networks (CNNs) for efficiently regressing a dense deformation field from a pair of images.

Abstract Objective Patients with spontaneous subarachnoid hemorrhage (SAH) may develop refractory arterial cerebral vasospasm (CVS), which is the leading cause of death in SAH patients. This study explored the clinical diagnostic value of serum miR‐195‐5p levels in CVS after SAH (SAH + CVS) and its relationship with the prognosis of SAH + CVS.

Abstract Aim The aims of this pilot study were to investigate the levels of biomarkers of microglial/macrophage activation—YKL‐40, sCD163, and sCD14—in patients with neuromyelitis optica spectrum disorder (NMOSD) and determine the possible associations between these biomarkers and Expanded Disability Status Scale (EDSS) scores.
