Growth Differentiation Factor 15 as a Cerebrospinal Fluid Biomarker for the Diagnosis and Prognosis of Leptomeningeal Metastasis

open access: yesAnnals of Neurology, EarlyView.
Objective As leptomeningeal metastasis (LM) has a poor prognosis, reliable cerebrospinal fluid (CSF) diagnostic biomarkers are urgently needed. This study evaluated the diagnostic value of CSF growth differentiation factor 15 (GDF15) in LM from lung adenocarcinoma (LUAD) and breast cancer (BC).

Facile Synthesis of a Bis‐α‐aryl‐Substituted Pyclen‐Based Heptadentate Lanthanide Chelator for Ultra‐Robust and High‐Contrast MRI Agents and for Radiopharmaceuticals

open access: yesAngewandte Chemie, EarlyView.
A facile synthesis involving a three‐component Petasis reaction is reported to construct bis‐α‐aryl‐substituted PCTAs. The synthesis is the simplest among all previously reported work on α‐substituted PCTAs. One of the isomers results in a Gd complex that showed significantly improved robustness despite being heptadentate and q = 2. This complex should

Serum Chitotriosidase Links to Activated Glia at Chronic Active Lesion Rims in Multiple Sclerosis Brain

open access: yesAnnals of Neurology, EarlyView.
Objective The objective of this study was to explore the association between 18 kDa translocator protein (TSPO)‐positron emission tomography (PET)–measurable glial activation and serum chitotriosidase (CHIT1) in people with multiple sclerosis (pwMS), and its expression in postmortem MS brain tissue.

Cerebral No‐Reflow after Thrombectomy: International Delphi Consensus on Definition and Imaging Assessment

open access: yesAnnals of Neurology, EarlyView.
Background The operational definition and imaging assessment of the no‐reflow phenomenon, a potential contributor to poor clinical outcome despite successful thrombectomy, remains debated. We aimed to develop expert‐based international consensus on the definition, assessment, and reporting standard of cerebral no‐reflow post‐thrombectomy. Methods Three‐

Prediction of First and Recurrent Falls in Parkinson's Disease

open access: yesAnnals of Neurology, EarlyView.
Objective To develop and externally validate prediction models for next‐year falls in Parkinson's disease (PD), and to evaluate the incremental value of imaging and fluid biomarkers. Methods We developed models in Parkinson's Progression Markers Initiative (PPMI) to predict next‐year falls with external validation in University of Pennsylvania (UPenn ...

Leveraging Metamaterial‐Inspired Wireless Resonator for Reliable Quantitative MRI at 1.5T: Linearity, Bias, and Repeatability Assessment

open access: yesAdvanced Physics Research, EarlyView.
This study designed a nonlinear‐response metamaterial‐inspired wireless resonator (MWR) and systematically evaluated the feasibility of using MWR for quantitative magnetic resonance imaging (qMRI), including T1/T2 mapping, apparent diffusion coefficient, and proton density fat fraction.
