Effects of virtual reality-based rehabilitation on cognitive function and mood in multiple sclerosis: A systematic review and meta-analysis of randomized controlled trials.

Background: Multiple sclerosis (MS) is a disabling neurological disease that causes cognitive impairment and mental problems that occur in all MS phenotypes but are most common in patients with secondary progressive MS. Various degrees of cognitive impairment and mental health concerns are common among patients with MS (PwMS). Virtual reality (VR)-based rehabilitation is an innovative approach aimed at enhancing cognitive function and mood in PwMS.

Feature separation and adversarial training for the patient-independent detection of epileptic seizures.

An epileptic seizure is the external manifestation of abnormal neuronal discharges, which seriously affecting physical health. The pathogenesis of epilepsy is complex, and the types of epileptic seizures are diverse, resulting in significant variation in epileptic seizure data between subjects. If we feed epilepsy data from multiple patients directly into the model for training, it will lead to underfitting of the model.

Patient-specific approach using data fusion and adversarial training for epileptic seizure prediction.

Epilepsy is the second common neurological disorder after headache, accurate and reliable prediction of seizures is of great clinical value. Most epileptic seizure prediction methods consider only the EEG signal or extract and classify the features of EEG and ECG signals separately, the improvement of prediction performance from multimodal data is not fully considered. In addition, epilepsy data are time-varying, with differences between each episode in a patient, making it difficult for traditional curve-fitting models to achieve high accuracy and reliability.

[Epilepsy detection and analysis method for specific patient based on data augmentation and deep learning].

In recent years, epileptic seizure detection based on electroencephalogram (EEG) has attracted the widespread attention of the academic. However, it is difficult to collect data from epileptic seizure, and it is easy to cause over fitting phenomenon under the condition of few training data. In order to solve this problem, this paper took the CHB-MIT epilepsy EEG dataset from Boston Children's Hospital as the research object, and applied wavelet transform for data augmentation by setting different wavelet transform scale factors.

Social cognition in multiple sclerosis and its subtypes: A meta-analysis.

Background: Multiple sclerosis (MS) is an immune-mediated demyelinating disease that disrupts several social cognitive abilities, including the theory of mind (ToM) and facial emotion recognition (FER). It is unclear how specific ToM subcomponents, including cognitive and affective ToM, are affected in patients with MS and the social cognitive abilities in MS subtypes.

Methods: A search of PubMed, Web of Science, and Embase databases was conducted until June 2020.

Empathy and Theory of Mind in Multiple Sclerosis: A Meta-Analysis.

Multiple sclerosis (MS) is an immune-mediated demyelinating disease of the central nervous system. Studies have shown that MS disrupts several social cognitive abilities [including empathy and theory of mind (ToM)]. Overall ToM deficits in MS are well documented, but how the specific ToM subcomponents and empathic capacity are affected remains unclear.

Retinal nerve fiber layer changes in migraine: a systematic review and meta-analysis.

Background: Migraine is one of the most common disabling diseases in the world. Its recurrent attacks may lead to abnormalities in the structure of the brain and retina. An increasing number of studies have investigated retinal nerve fiber layer (RNFL) thickness alterations in migraine by the optical coherence tomography (OCT); however, no consensus has yet reached.

Theory of mind in adults with traumatic brain injury: A meta-analysis.

Studies of abnormal theory of mind (ToM) performance in adult patients with traumatic brain injury (TBI) have reported inconsistent results. Therefore, we conducted a meta-analysis to characterize ToM performance in adult patients with TBI. Random-effects models were employed to estimate the overall effect size and the differential effect sizes across different ToM aspects.

Empathy and theory of mind in multiple sclerosis: A protocol for systematic review and meta-analysis.

Background: Multiple sclerosis (MS) is an immune-mediated demyelinating disease of the central nervous system (CNS). Recently, numerous studies have shown that MS disrupts a number of social cognitive abilities, including empathy, theory of mind (ToM), and facial emotion recognition. In contrast to well-documented deficits in the core social cognitive domains of ToM and facial emotion recognition, it is not clear the broad and specific subcomponents of empathy processing affected.

Social cognition in multiple sclerosis and its subtypes: A protocol for systematic review and meta-analysis.

Background: Multiple sclerosis (MS) is an inflammatory and degenerative neurological disorder of the central nervous system. Cognitive impairment is frequent in MS patients, which not only includes deficits in abilities assessed by traditional neuropsychological batteries, but also often features impairments in social cognition (including theory of mind and facial emotion recognition). Recently, numerous studies have assessed social cognition performance in MS.

Screen-printed microfluidic dielectrophoresis chip for cell separation.

Dielectrophoresis (DEP), the induced motion of polarizable particles in a non-uniform electric field, has been proven as a perfect candidate to transport, accumulate, separate and characterize micro-/nano-scale bioparticles in microfluidic systems. However, conventional fabrication technologies are complex, time-consuming and relatively expensive, leading to low throughput of the DEP-based systems. In this paper, we report a novel microfluidic alternating current DEP (AC-DEP) chip fabricated via inexpensive screen printing method.
