Complete resolution of restless legs syndrome following ischemic stroke of the right middle cerebral artery.

Stroke-related restless legs syndrome (sRLS) is an emerging clinical entity, with a clear relationship between stroke and the occurrence of restless legs syndrome (RLS). Dopamine dysregulation has been observed in sRLS of the lenticulostriate region with increased dopamine precursor and decreased dopamine transporter. The aim of this work is to explore an original case of regressive RLS following stroke.

Anatomy-based correction of kidney PVE on [Formula: see text] SPECT images.

Background: In peptide receptor radionuclide therapy (PRRT), accurate quantification of kidney activity on post-treatment SPECT images paves the way for patient-specific treatment. Due to the limited spatial resolution of SPECT images, the partial volume effect (PVE) is a significant source of quantitative bias. In this study, we aimed to evaluate the performance and robustness of anatomy-based partial volume correction (PVC) algorithms to recover the accurate activity concentration of realistic kidney geometries on [Formula: see text]Lu SPECT images recorded under clinical conditions.

Does Spinocerebellar ataxia 27B mimic cerebellar multiple system atrophy?

Background: Whether spinocerebellar ataxia 27B (SCA27B) may present as a cerebellar multiple system atrophy (MSA-C) mimic remains undetermined.

Objectives: To assess the prevalence of FGF14 (GAA) expansions in patients with MSA-C, to compare SCA27B and MSA-C clinical presentation and natural history.

Methods: FGF14 expansion screening combined with longitudinal deep-phenotyping in a prospective cohort of 195 patients with sporadic late-onset cerebellar ataxia.

PiDeeL: metabolic pathway-informed deep learning model for survival analysis and pathological classification of gliomas.

Motivation: Online assessment of tumor characteristics during surgery is important and has the potential to establish an intra-operative surgeon feedback mechanism. With the availability of such feedback, surgeons could decide to be more liberal or conservative regarding the resection of the tumor. While there are methods to perform metabolomics-based tumor pathology prediction, their model complexity predictive performance is limited by the small dataset sizes.

Natural History and Phenotypic Spectrum of GAA-FGF14 Sporadic Late-Onset Cerebellar Ataxia (SCA27B).

Background: Heterozygous GAA expansions in the FGF14 gene have been related to autosomal dominant cerebellar ataxia (SCA27B-MIM:620174). Whether they represent a common cause of sporadic late-onset cerebellar ataxia (SLOCA) remains to be established.

Objectives: To estimate the prevalence, characterize the phenotypic spectrum, identify discriminative features, and model longitudinal progression of SCA27B in a prospective cohort of SLOCA patients.
