Cortical lesions impact cognitive decline in multiple sclerosis via volume loss of nonlesional cortex.

Objective: To assess the interrelationship between cortical lesions and cortical thinning and volume loss in people with multiple sclerosis within cortical networks, and how this relates to future cognition.

Methods: In this longitudinal study, 230 people with multiple sclerosis and 60 healthy controls underwent 3 Tesla MRI at baseline and neuropsychological assessment at baseline and 5-year follow-up. Cortical regions (N = 212) were divided into seven functional networks.

Antibiotic Utilization Among People With Multiple Sclerosis in the Netherlands, 2018-2020.

Purpose: The purpose of this study was to describe the intensity and patterns of antibiotic drug use among people with multiple sclerosis (pwMS) in the Netherlands.

Methods: People with prevalent MS between 1 January 2018 and 31 December 2020 were identified using ambulatory hospital records from the PHARMO Database Network that contains routinely collected healthcare data from the Netherlands. Out-patient pharmacy dispensing data were used to assess type of antibiotic, dosage, and amounts dispensed.

Prevalence and incidence of multiple sclerosis in the Netherlands.

Background: The rising prevalence estimates of multiple sclerosis (MS) globally underscore the imperative for up-to-date epidemiological data specific to the Netherlands.

Methods: Data from two Dutch healthcare databases (Nivel Primary Care Database and Vektis Database) comprising both general practices and hospital electronic health records in 2019 were combined to assess age- and sex-standardized MS prevalence and incidence estimates. Differences in prevalence estimates based on latitude and between primary versus secondary care records were examined.

Discontinuation of First-Line Disease-Modifying Therapy in Patients With Stable Multiple Sclerosis: The DOT-MS Randomized Clinical Trial.

Importance: Increasing numbers of people with multiple sclerosis (MS) use disease-modifying therapy (DMT). Long-term stable disease while taking such medications provides a rationale for considering DMT discontinuation given patient burden, costs, and potential adverse effects of immunomodulating therapy.

Objective: To investigate whether first-line DMT can be safely discontinued in patients with long-term stable MS.

Understanding the complex network of objectively assessed cognition and self-reported psychological symptoms in people with multiple sclerosis.

Background: Literature on the intricate relationship between self-reported and objectively assessed cognitive functioning suggests a discrepancy between self-reported cognitive complaints (SCC) and actual test performance.

Objectives: To investigate the interplay between patient-reported outcome measures (PROMs) and objective cognitive functioning using network analysis in people with multiple sclerosis (PwMS).

Methods: We collected PROMs on anxiety, depression, fatigue and SCC, and cognitive functioning across six domains ( = 703 PwMS; 71% female, mean age = 46.
