Plasma fibronectin is a prognostic biomarker of disability in Parkinson's disease: a prospective, multicenter cohort study.

In a prospective longitudinal study with 218 Parkinson's disease (PD) patients in the discovery cohort and 84 in the validation cohort, we aimed to identify novel blood biomarkers predicting disability milestones in PD. Through Least Absolute Shrinkage and Selection Operator-Cox (Lasso-Cox) regression, developed nomogram predictive model and Linear mixed-effects models, we identified low level of plasma fibronectin (pFN) as one of the best-performing risk markers in predicting disability milestones. A low level of pFN was associated with a short milestone-free survival period in PD.

Repetitive transcranial magnetic stimulation alleviates motor impairment in Parkinson's disease: association with peripheral inflammatory regulatory T-cells and SYT6.

Background: Repetitive transcranial magnetic stimulation (rTMS) has been used to treat various neurological disorders. However, the molecular mechanism underlying the therapeutic effect of rTMS on Parkinson's disease (PD) has not been fully elucidated. Neuroinflammation like regulatory T-cells (Tregs) appears to be a key modulator of disease progression in PD.

Correlations of gray matter volume with peripheral cytokines in Parkinson's disease.

Introduction: Peripheral cytokine levels may affect specific brain volumes. Few studies have examined this possible relationship.

Objective: In a case-control study, we used magnetic resonance imaging (MRI) voxel-based morphological analysis techniques to examine the relationship between gray matter volume changes and cognitive, motor and emotional dysfunction as well as between gray matter volume changes and peripheral blood cytokine levels.

Risk of aspiration pneumonia and hospital mortality in Parkinson disease: A systematic review and meta-analysis.

Background And Purpose: This study was undertaken to conduct a meta-analysis on the prevalence of aspiration pneumonia (AP) and hospital mortality in Parkinson disease (PD) as well as the risk of AP in PD patients compared to controls.

Methods: We searched MEDLINE and Embase from inception to 19 March 2024 to identify cross-sectional, cohort, and case-control studies comparing the frequency of AP and hospital mortality in PD patients. We computed risk ratios (RRs) with accompanying 95% confidence intervals (CIs) for each study and pooled the results using a random-effects meta-analysis.

Ultra-high-field 7T MRI in Parkinson's disease: ready for clinical use?-a narrative review.

Background And Objective: The maturation of ultra-high-field magnetic resonance imaging (MRI) [≥7 Tesla (7T)] has improved our capability to depict and characterise brain structures efficiently, with better signal-to-noise ratio (SNR) and spatial resolution. We evaluated whether these improvements benefit the clinical detection and management of Parkinson's disease (PD).

Methods: We performed a literature search in March 2023 in PubMed (MEDLINE), EMBASE and Google Scholar for articles on "7T MRI" AND "Parkinson*", written in English, published between inception and 1st March, 2023, which we synthesised in narrative form.

Essential tremor.

Essential tremor (ET) is one of the most common movement disorders, with a reported >60 million affected individuals worldwide. The definition and underlying pathophysiology of ET are contentious. Patients present primarily with motor features such as postural and action tremors, but may also have other non-motor features, including cognitive impairment and neuropsychiatric symptoms.
