Long-term exposure to multiple air pollutants and risk of Parkinson's disease: a population-based multipollutant model study.
Recent evidence suggests brain-first Parkinson's disease (PD) may start from the olfactory system, indicating potential inhalational exposure to causal agents. We investigated the impact of long-term exposure to various air pollutants on PD incidence using both single- and multi-pollutant models to account for interactions between pollutants. ⋯ This nationwide cohort study employing multiple-pollutant models for considering the interaction effects revealed an association between exposure to multiple air pollutants and the risk of PD, emphasising the need for early prevention strategies.

Real-world multicentre cohort study on choices and effectiveness of immunotherapies in NMOSD and MOGAD.
Recurrent attacks in neuromyelitis optica spectrum disorders (NMOSDs) or myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) can lead to severe disability. We aimed to analyse the real-world use of immunotherapies in patients with NMOSD and MOGAD, focusing on changes in treatment strategies, effects on attack rates (ARR) and risk factors for attacks. ⋯ This study provides insights into the evolving treatment landscape and effectiveness of immunotherapies in NMOSD and MOGAD. Established off-label therapies continue to play an important role, especially for patients with stable disease, with emerging evidence supporting newly approved therapies. Future studies are needed to refine treatment algorithms and address the ongoing uncertainties in MOGAD management.

Left atrial appendage occlusion in patients with atrial fibrillation and intracerebral haemorrhage associated with cerebral amyloid angiopathy: a multicentre observational study and pooled analysis of published studies.
Cerebral amyloid angiopathy (CAA) is a common cause of intracerebral haemorrhage (ICH) with a high recurrence risk. Left atrial appendage occlusion (LAAO) is a method for ischaemic stroke prevention in patients with atrial fibrillation (AF), potentially reducing the risk of intracranial bleeding in CAA-associated ICH. We aimed to determine the outcomes of patients with AF with CAA-associated ICH undergoing LAAO. ⋯ CRD42023415354.

Optical coherence tomography in secondary progressive multiple sclerosis: cross-sectional and longitudinal exploratory analysis from the MS-SMART randomised controlled trial.
Optical coherence tomography (OCT) inner retinal metrics reflect neurodegeneration in multiple sclerosis (MS). We explored OCT measures as biomarkers of disease severity in secondary progressive MS (SPMS). ⋯ In our cohort of people with SPMS and long disease duration, OCT measures correlated with SDMT and deep grey matter volume at baseline; EDSS, T25FW and whole brain volume change at follow-up.

How well do plasma Alzheimer's disease biomarkers reflect the CSF amyloid status?
Can plasma biomarkers as well as cerebrospinal fluid (CSF) perform in the separation of amyloid-beta-positive (Aβ+) vs amyloid-beta-negative (Aβ-) groups across an age range seen in an NHS cognitive disorder clinic? ⋯ There was variable performance of plasma biomarkers to recapitulate the CSF assay. Both p-tau217 and p-tau217/Aβ42 showed excellent promise as surrogates of CSF amyloid status, although with slightly reduced performance in older individuals. There was poorer discriminatory ability for p-tau181 and Aβ42/40. Further research is needed to address potential age-related confounds.
