Neurofilament Light Chain as a Discriminator of Disease Activity Status in MOG Antibody-Associated Disease.

Background And Objectives: In patients with myelin oligodendrocyte glycoprotein (MOG) antibody-associated disease (MOGAD), acute disease activity is generally identified through medical history, neurologic examination, and imaging. However, these may be insufficient for detecting disease activity in specific conditions. This study aimed to investigate the dynamics of serum neurofilament light chain (sNfL) and serum glial fibrillary acidic protein (sGFAP) after clinical attacks and to assess their utility in discriminating attacks from remission in patients with MOGAD.

Child Neurology: Neurophysiologic and Anatomical Correlates in Startle Epilepsy: A Comprehensive SEEG Investigation for Successful Resective Surgery.

Startle epilepsy, characterized by startle-provoked epileptic seizures, was historically recognized as one of the reflex epilepsies but currently lacks classification as a specific epileptic syndrome because of insufficient characterization. This study presents an institutional experience and review of relevant literature focusing on the neurophysiologic and anatomical aspects of startle epilepsy. We describe a pediatric patient with an underlying structural etiology of left frontal encephalomalacia who continued to experience disabling seizures despite multiple antiseizure medications and previous palliative surgery.

Development of a CT image-based virtual atelectasis simulation model and noninvasive lung nodule localization system.

Background: In the process of video-assisted thoracoscopic surgery (VATS) for lung nodule resection, lung is leaded to atelectasis. However, preoperative computed tomography (CT) images are taken during inspiration, which means they differ significantly from the lung status observed during surgery. Consequently, this discrepancy can make the localization of small or subsolid nodules challenging during the operation.

The Inferior Cerebellar Peduncle Sign: A Novel Imaging Marker for Differentiating Multiple System Atrophy Cerebellar Type from Spinocerebellar Ataxia.

Background And Purpose: The hot cross bun (HCB) sign is a hallmark feature of multiple system atrophy with predominant cerebellar ataxia (MSA-C), typically observed in advanced stages of the disease; however, it can also present in other conditions such as spinocerebellar ataxia (SCA), making the differentiation challenging. The middle cerebellar peduncle (MCP) sign may be observed in various medical conditions and in healthy individuals. We hypothesized that the inferior cerebellar peduncle (ICP), known to be affected in MSA-C, may exhibit hyperintensity on fluid-attenuated inversion recovery (FLAIR) imaging, potentially aiding in differentiating MSA-C from SCA.

Circular RNAs trigger nonsense-mediated mRNA decay.

Circular RNAs (circRNAs) are covalently closed single-stranded RNAs produced predominantly through a back-splicing process. They play regulatory roles in various biological and physiological processes; however, the molecular mechanisms by which circRNAs operate remain unclear. Herein, we demonstrate that circRNAs facilitate rapid mRNA degradation through RNA-RNA interactions between circRNAs and the 3' untranslated regions (3' UTRs) of mRNAs.

Imlunestrant with or without Abemaciclib in Advanced Breast Cancer.

Background: Imlunestrant is a next-generation, brain-penetrant, oral selective estrogen-receptor (ER) degrader that delivers continuous ER inhibition, even in cancers with mutations in the gene encoding ERα ().

Methods: Patients who underwent hUCB-MSC implantation for MFC cartilage defects involved in isolated medial compartment osteoarthritis were included. The patients were divided into 2 groups, those with MFC defects located within the anterior-central portion (group A) and those with MFC defects extending to the posterior portion (group P).

Consensus Report on the Use of Continuous Glucose Monitoring in Chronic Kidney Disease and Diabetes.

This report represents the conclusions of 15 experts in nephrology and endocrinology, based on their knowledge of key studies and evidence in the field, on the role of continuous glucose monitors (CGMs) in patients with diabetes and chronic kidney disease (CKD), including those receiving dialysis. The experts discussed issues related to CGM accuracy, indications, education, clinical outcomes, quality of life, research gaps, and barriers to dissemination. Three main goals of management for patients with CKD and diabetes were identified: (1) greater use of CGMs for better glycemic monitoring and management, (2) further research evaluating the accuracy, feasibility, outcomes, and potential value of CGMs in patients with end-stage kidney disease (ESKD) on hemodialysis, and (3) equitable access to CGM technology for patients with CKD.
