Neuroimaging Features, Follow-Up Analyses, and Comparisons Between Asymptomatic and Symptomatic Neurosyphilis.

Introduction: Many studies have explored the imaging characteristics of patients with neurosyphilis, but no systematic study has been made on the neuroimaging changes after anti-syphilitic treatment. The purpose of this study was to examine neuroimaging differences before and after treatment, comparing patients with asymptomatic and symptomatic neurosyphilis.

Methods: A total of 102 patients with neurosyphilis, including 60 cases of symptomatic neurosyphilis and 42 cases of asymptomatic neurosyphilis, were identified between December 2012 and June 2019.

Efficacy and safety of endovascular thrombectomy in mild ischemic stroke: results from a retrospective study and meta-analysis of previous trials.

Background: Mechanical thrombectomy has been proven as a standard care for moderate to severe ischemic stroke with anterior large vessel occlusion (LVO); however, whether it is equally effective in mild ischemic stroke (MIS) is controversial.

Methods: In this retrospective study, a total of 177 Chinese patients presenting with MIS (NIHSS ≤8) and LVO between January 2014 and September 2017 from seven comprehensive stroke centers were identified. Odds of good outcome with endovascular thrombectomy versus medical treatment were obtained by logistic regression analysis and propensity-score matching method, and a meta-analysis pooled results from six studies (n = 733).

The influence of initial symptoms on phenotypes in spinocerebellar ataxia type 3.

Background: Spinocerebellar ataxia type 3 (SCA3) is a rare, inherited form of ataxia that leads to progressive neurodegeneration. The initial symptoms could affect clinical phenotypes in neurodegenerative diseases, such as Parkinson's disease and amyotrophic lateral sclerosis. However, the contribution of initial symptoms to the phenotypes of SCA3 has been scarcely investigated.

Homozygote of spinocerebellar Ataxia type 3 correlating with severe phenotype based on analyses of clinical features.

Background: Spinocerebellar ataxia type 3 (SCA3) is the most common subtype of SCAs worldwide. SCA3 homozygote is defined as expanded CAG repeats in both alleles that might exhibit severe phenotype due to gene dosage effect. However, a study on the systematic comparison of clinical phenotypes between homozygotes and heterozygotes to indicate these verity of phenotypes of homozygotes is still lacking.

Bidirectional Connections between Depression and Ataxia Severity in Spinocerebellar Ataxia Type 3 Patients.

Background: Spinocerebellar ataxia type 3 (SCA3), which is the most common subtype of SCA worldwide, exhibits common neuropsychological symptoms such as depression. However, the contribution of depression to the severity of SCA3 has not yet been thoroughly investigated.

Methods: The present study investigated the prevalence of depression using Beck depression inventory in 104 molecularly confirmed SCA3 patients from China.
