Lymphocyte-based ratios for predicting respiratory failure in Guillain-Barré syndrome.

Purpose: Up to 20-30% of patients with Guillain-Barré syndrome (GBS) suffer serious clinical manifestations such as respiratory failure. We aim to determine whether two new prognostic biomarkers, the neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR), could reliably predict respiratory failure in GBS.we MATERIALS AND METHODS: Data from 426 patients diagnosed at our center with GBS between January 2015 and July 2019 were retrospectively analyzed.

Clinical value of C-reactive protein/albumin ratio in Guillain-Barré syndrome.

Background: Respiratory failure in patients with Guillain-Barré syndrome (GBS) can lead to serious complications and dysfunctions, emphasizing the importance of early detection. The C-reactive protein-to-albumin ratio (CAR) is emerging as a novel inflammatory marker for predicting neurological outcome. We aimed to identify the association of CAR with respiratory failure and short-term outcome in GBS patients.

LRP10 Mutations May Correlate with Sporadic Parkinson's Disease in China.

LDL receptor-related protein (LRP) 10 was recently identified as a Parkinson's disease gene through genome-wide linkage and sequencing analysis, but its role in Parkinson's disease in various populations is still unclear. The aim of this study was to determine the frequency and spectrum of LRP10 mutations in a cohort of Parkinson's disease patients from mainland China. All LRP10 exons and their flanking intron regions were screened by direct sequencing in 567 unrelated Parkinson's disease patients and 600 unrelated controls.

Methods: In the cross-sectional study, we grouped 290 definite or probable ET patients based on their MT conditions.

Acute Flaccid Paralysis as the Initial Manifestation of Japanese Encephalitis: a Case Report.

Japanese encephalitis (JE) is a clinical disease caused by inflammation of the central nervous system. The symptoms of this disease range broadly in severity from mild febrile illness to acute meningomyeloencephalitis. JE has been associated with a variety of neurological abnormalities, such as altered sensorium, seizures, focal neurological deficit, and acute flaccid paralysis (AFP).

Clinical characteristics of patients with essential tremor or essential tremor plus.

Background: The International Parkinson and Movement Disorder Society introduced the category of essential tremor (ET)-plus in its new ET classification scheme, but how the clinical correlates of ET-plus differ from those of "pure" ET is unclear. By comparing the clinical characteristics of ET and ET-plus patients, we expect to better understand the impact and invoked questions of the new classification on clinical practice.

Methods: We reviewed the medical records of 280 ET syndrome patients in an ongoing cross-sectional study in a Chinese population and reclassified them according to the new criteria.

Clinical features of multiple system atrophy with or without rapid eye movement behavior disorder: a cross-sectional study in southwest China.

Objective: The aim of this study was to investigate the prevalence of rapid eye movement behavior disorder (RBD) in Chinese patients with multiple system atrophy (MSA) and to compare motor and non-motor symptoms and sleep disturbance of MSA patients with and without RBD.

Methods: A total of 55 patients who were consecutively admitted to West China Hospital of Sichuan University from 2016 to 2019 and subsequently diagnosed with probable MSA were enrolled in this cross-sectional study. The diagnosis of RBD was based on the results of video polysomnography (PSG) and a history of abnormal sleep-related behaviors.

Prevalence and Risk Factors of Depression and Anxiety in Essential Tremor Patients: A Cross-Sectional Study in Southwest China.

Association between REM sleep behavior disorder and impulsive-compulsive behaviors in Parkinson's disease: a systematic review and meta-analysis of observational studies.

Background: Both REM sleep behavior disorder (RBD) and impulsive-compulsive behaviors (ICBs) are well-recognized non-motor features in patients with Parkinson's disease (PD). Studies have given contradictory results about the potential association between RBD and ICBs.

Methods: PubMed, Embase (via Ovid), and the Cochrane Central Registry of Controlled Trials (CENTRAL) databases were systematically searched till August 20, 2019 to identify studies that explored the possible correlation between RBD and ICBs in patients with PD.

Lack of association between appendectomy and Parkinson's disease: a systematic review and meta-analysis.

Background: Accumulation of aggregated α-synuclein from the enteric nervous system is believed to be involved in the pathogenesis of Parkinson's disease (PD). The appendix contains abundant α-synuclein and lacks a blood-tissue barrier, suggesting that appendectomy might reduce α-synuclein aggregation, and therefore the risk of PD. Studies on this intriguing possibility have not come to consistent conclusions.

Frequency and factors related to drooling in Chinese patients with multiple system atrophy: a cross-sectional study.

Purpose: Drooling is a common symptom of neurodegenerative diseases. We aimed to explore the frequency of drooling and its relationship to clinical features in a relatively large cohort of Chinese patients with multiple system atrophy (MSA).

Methods: We conducted a cross-sectional survey of 143 patients with MSA.

Systematic review and meta-analysis of observational studies to understand the prevalence of restless legs syndrome in multiple sclerosis: an update.

Objective: Multiple sclerosis (MS) is related to the demyelination of intracranial nerves at multiple sites, while restless legs syndrome (RLS) appears to be caused by dysfunction of the dopaminergic system. Since RLS prevalence is higher among MS patients than in the general population, we carried out an updated meta-analysis to understand whether the two diseases might be associated.

Method: Web of Science, PubMed, Embase, Chinese National Knowledge Infrastructure, Wanfang, and SinoMed databases were searched for observational and case-controlled studies of RLS prevalence in MS.

Meta-analysis of the association between ZNF512B polymorphism rs2275294 and risk of amyotrophic lateral sclerosis.

Amyotrophic lateral sclerosis (ALS), the most common motor neuron disease, appears to result from the combination of genetic and environmental factors. Whether the rs2275294 polymorphism in the ZNF512B gene influences ALS risk is controversial. We meta-analysed the association between rs2275294 and ALS risk based on evidence published in the PubMed database.

Prevalence of restless legs syndrome in Parkinson's disease: a systematic review and meta-analysis of observational studies.

Objective: Restless legs syndrome (RLS) and Parkinson's disease (PD) are common neurological disorders that respond to dopaminergic therapy. RLS prevalence among people with PD varies widely (0-38%) in the literature, complicating efforts to understand whether the two diseases might be associated.

Method: The databases Web of Science, PubMed, Embase, Chinese National Knowledge Infrastructure, Wanfang, and SinoMed were searched for observational and case-control studies of RLS prevalence in PD.

Absence of association of the Ala58Val (rs17571) CTSD gene variant with Parkinson's disease or amyotrophic lateral sclerosis in a Han Chinese population.

Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS) and Alzheimer's disease (AD) are neurodegenerative diseases that may share genetic risk factors. The exon variant Aal58Val (rs17571) in CTSD was recently associated with AD, leading us to examine whether it also affects risk of ALS and PD. The rs17571 variant was genotyped using the ligase detection reaction in 569 Han Chinese patients with PD, 301 patients with ALS, and healthy controls age- and gender-matched to each patient group.

Polymorphism in MIR4697 but not VPS13C, GCH1, or SIPA1L2 is associated with risk of Parkinson's disease in a Han Chinese population.

A large meta-analysis recently identified six new loci associated with risk of PD, but subsequent studies have given discrepant results. Here we conducted a case-control study in a Han Chinese population in an attempt to clarify risk associations in Chinese. Among the four single-nucleotide polymorphisms (SNPs) that we examined - VPS13C-rs2414739, MIR4697-rs329648, GCH1-rs11158026, and SIPA1L2- rs10797576 we detected a significant association between rs329648 and risk of developing PD in a recessive model.
