    CONCLUSIONS AND RELEVANCE: In this study, activated glial markers (in particular GFAP) and neurofilament heavy chain were associated specifically with nonrelapsing progressive disease outcomes (independent of acute inflammatory activity). Elevated CSF GFAP was associated with long-term MS disease progression.
  • Characterization of cortico-meningeal translocator protein expression in multiple sclerosis

    Tuesday, January 30, 2024
    Author(s): Elena Herranz,Constantina A Treaba,Valeria T Barletta,Ambica Mehndiratta,Russell Ouellette,Jacob A Sloane,Carolina Ionete,Suma Babu,Marina Mastantuono,Stefano Magon,Marco L Loggia,Meena M Makary,Jacob M Hooker,Ciprian Catana,Revere Kinkel,Richard Nicholas,Eric C Klawiter,Roberta Magliozzi,Caterina Mainero

    Compartmentalized meningeal inflammation is thought to represent one of the key players in the pathogenesis of cortical demyelination in multiple sclerosis. Positron emission tomography targeting the 18 kDa mitochondrial Translocator Protein (TSPO) is a molecular-specific approach to quantify immune cell-mediated density in the cortico-meningeal tissue compartment in vivo. The aim of this study was to characterize cortical and meningeal TSPO expression in a heterogeneous cohort of multiple...
  • Implementing Shared Decision-Making for Multiple Sclerosis: The MS-SUPPORT Tool

    Monday, November 06, 2023
    Author(s): Nananda F Col,Andrew J Solomon,Enrique Alvarez,Lori Pbert,Carolina Ionete,Idanis BerriosMorales,Jennifer Chester,Christen Kutz,Crystal Iwuchukwu,Terrie Livingston,Vicky Springmann,Hannah V Col,Long H Ngo

    CONCLUSIONS: MS-SUPPORT was strongly endorsed by patients and is feasible to use in clinical settings. MS-SUPPORT increased the short-term probability of taking and adhering to a DMT, and improved long-term mental health. Study limitations include selection bias, response bias, social desirability bias, and recall bias. Exploring approaches to reinforcement and monitoring its implementation in real-world settings should provide further insights into the value and utility of this new SDM tool.
  • Improved Performance for PMSM Sensorless Control Based on Robust-Type Controller, ESO-Type Observer, Multiple Neural Networks, and RL-TD3 Agent

    Friday, July 14, 2023

    Source: Sensors (Basel, Switzerland)
    This paper summarizes a robust controller based on the fact that, in the operation of a permanent magnet synchronous motor (PMSM), a number of disturbance factors naturally occur, among which both changes in internal parameters (e.g., stator resistance R(s) and combined inertia of rotor and load J) and changes in load torque T(L) can be mentioned. In this way, the performance of the control system can be maintained over a relatively wide range of variation in the types of parameters mentioned...

    A small proportion of multiple sclerosis (MS) patients develop new disease activity soon after starting anti-CD20 therapy. This activity does not recur with further dosing, possibly reflecting deeper depletion of CD20-expressing cells with repeat infusions. We assessed cellular immune profiles and their association with transient disease activity following anti-CD20 initiation as a window into relapsing disease biology. Peripheral blood mononuclear cells from independent discovery and validation...

    We recently discovered that superparamagnetic iron oxide nanoparticles (SPIONs) can levitate plasma biomolecules in the magnetic levitation (MagLev) system and cause formation of ellipsoidal biomolecular bands. To better understand the composition of the levitated biomolecules in various bands, we comprehensively characterized them by multi-omics analyses. To probe whether the biomolecular composition of the levitated ellipsoidal bands correlates with the health of plasma donors, we used plasma...

    Despite widespread screening and active management of syphilis infection, the rate of secondary and tertiary syphilis has increased over the past decade in the United States, especially with human immunodeficiency virus co-infection. We report a case of ischemic strokes in the middle cerebral artery (MCA) territory with focal stenosis of the left M1 segment of the MCA resulting from neurosyphilis with manifestation of subacute intermittent right-sided hemi-body numbness and transient word...
  • The impact of socioeconomic status on mental health and health-seeking behavior across race and ethnicity in a large multiple sclerosis cohort

    Saturday, December 25, 2021
    Author(s): Daniela A Pimentel Maldonado,Justin R Eusebio,Lilyana Amezcua,Eleni S Vasileiou,Ellen M Mowry,Christopher C Hemond,Raffaella Umeton Pizzolato,Idanis Berrios Morales,Irina Radu,Carolina Ionete,Kathryn C Fitzgerald

    CONCLUSION: Higher SES was associated with a lower burden of psychiatric symptoms and with a higher likelihood of self-reported symptom recovery after receiving mental health treatment. Attitudes regarding mental health care delivery in MS varied according to racial and ethnic background. Future longitudinal studies in more diverse populations should assess whether co-location of mental health services with MS care helps to reduce the gap between access and need of mental health care in MS.
  • Non-ambulatory measures of lower extremity sensorimotor function are associated with walking function in Multiple Sclerosis

    Thursday, June 17, 2021
    Author(s): Sumire Sato,John Buonaccorsi,Jules D Miehm,Jongil Lim,Caitlin Rajala,Farnaz Khalighinejad,Carolina Ionete,Jane A Kent,Richard E A van Emmerik
    Source: Multiple sclerosis and related disorders
    CONCLUSIONS: Foot-tap performance and plantar cutaneous sensitivity but not ankle proprioception differed between MS subtypes. Lower walking performance was associated with lower foot-tapping and plantar cutaneous sensitivity in the RRMS but not the PMS group. This result suggests a change in the relationship of lower extremity sensorimotor function to walking performance in the PMS subtype.
  • Alemtuzumab outcomes by age: Post hoc analysis from the randomized CARE-MS studies over 8 years

    Thursday, January 21, 2021
    Author(s): Ann D Bass,Rafael Arroyo,Aaron L Boster,Alexey N Boyko,Sara Eichau,Carolina Ionete,Volker Limmroth,Carlos Navas,Daniel Pelletier,Carlo Pozzilli,Jennifer Ravenscroft,Livia Sousa,Mar Tintoré,Bernard M J Uitdehaag,Darren P Baker,Nadia Daizadeh,Zia Choudhry,David Rog,CARE-MS I, CARE-MS II, CAMMS03409, and TOPAZ investigators

    Source: Multiple sclerosis and related disorders
    Multiple sclerosis (MS) is a chronic and progressive neurological disease characterized by recurrent episodes of inflammatory demyelination of the brain and spinal cord. Alemtuzumab has been previously shown in large phase III trials to be an effective therapy in reducing MS clinical flares as well as new radiological activity and atrophy rates. The purpose of this study was to examine real-world effectiveness and safety data from a large cohort of people treated with alemtuzumab at an academic...
