Local abnormal white matter microstructure in the spinothalamic tract in people with chronic neck and shoulder pain.
Front Neurosci
January 2025
Department of Radiology, Affiliated Hospital of North Sichuan Medical College, Nanchong, China.
Objective: To investigate differences in the microstructure of the spinothalamic tract (STT) white matter in people with chronic neck and shoulder pain (CNSP) using diffusion tensor imaging, and to assess its correlation with pain intensity and duration of the pain.
Materials And Methods: A 3.0T MRI scanner was used to perform diffusion tensor imaging scans on 31 people with CNSP and 24 healthy controls (HCs), employing the Automatic Fiber Segmentation and Quantification (AFQ) method to extract the STT and quantitatively analyze the fractional anisotropy (FA) and mean diffusivity (MD), reflecting the microstructural integrity of nerve fibers.
H syndrome with bilateral choroidal osteoma: Coincidence or association?
Eur J Ophthalmol
January 2025
Department of Medical Genetics, Istanbul Medipol University, Istanbul, Turkey.
Purpose: To report a case with bilateral corneal arcus and bilateral choroidal osteoma associated with H syndrome.
Methods: Descriptive case report.
Results: A 16-year-old girl with H syndrome was followed up in the pediatric nephrology clinic for chronic renal failure and was consulted to the ophthalmology clinic.
Variation in compressive mechanical properties between subacute and chronic venous thrombosis in a novel unilateral iliac thrombosis model.

Department of Surgery, Section of Vascular Surgery, Conrad Jobst Vascular Laboratories, University of Michigan Health System, Ann Arbor, MI, USA.
Interventional therapies to relieve chronic deep vein thrombosis (DVT) fail through inability to penetrate, cross, and remove the occlusion. Development of suitable tools requires fundamental understanding of chronic DVT mechanical properties and a reliable model for testing. Female farm swine underwent a novel, endovenous generation of long-segment unilateral iliac vein thrombosis.

January 2025
Department of Neurology, Haiyan People's Hospital Jiaxing, Zhejiang, China.
This study aimed to evaluate changes in cerebral blood flow and perioperative outcomes in patients with unilateral symptomatic carotid artery stenosis before and after carotid artery stenting (CAS), providing insights to guide surgical decision-making. Ninety-six patients with moderate to severe unilateral symptomatic carotid artery stenosis (>50%) admitted to the Neurology Department of the Second Affiliated Hospital of Zhejiang University from June 2023 to April 2024 were included. All patients underwent CAS and magnetic resonance imaging, including diffusion-weighted imaging (DWI) and 3D quasi-continuous arterial spin-labeled perfusion imaging, within 3 days preoperatively and on the third postoperative day.

Eur J Neurosci
January 2025
WRIISC-Women, VA Palo Alto Health Care System, Palo Alto, California, USA.
Combination of structural and functional brain connectivity methods provides a more complete and effective avenue into the investigation of cortical network responses to traumatic brain injury (TBI) and subtle alterations in brain connectivity associated with TBI. Structural connectivity (SC) can be measured using diffusion tensor imaging to evaluate white matter integrity, whereas functional connectivity (FC) can be studied by examining functional correlations within or between functional networks. In this study, the alterations of SC and FC were assessed for TBI patients, with and without chronic symptoms (TBIcs/TBIncs), compared with a healthy control group (CG).
