istence of SS with MG is quite rare. The onset of MG may occur before or after the diagnosis of SS. Co-morbidity with MG does not seem to adversely affect the course of SS. Thus, controlling the progress of MG is the critical aspect of treatment.Objective Chemotherapy and hematopoietic stem cell transplantation (HSCT) play important roles in clinical etiology, symptoms, signs, imaging findings, and biochemical parameters for inducing posterior reversible encephalopathy syndrome (PRES) in pediatric oncologic diseases. We aimed to evaluate various risk factors of pediatric oncologic diseases after conducting chemotherapy and HSCT to induce PRES for predicting the clinical prognosis frequency. Methods The literature was performed on PubMed, Web of Science, and Embase databases to recognize the qualified studies. The odds ratios (ORs) of related risk factors and their corresponding 95% confidence intervals (CIs) were used to compute the pooled assessments of the outcomes. Results Six studies were included in the meta-analysis, involving 828 records. The risk of female children has a significantly higher incidence than male children in oncologic age groups of PRES. Children over the age of 10 years old in oncologic age groups develop a significantly incre, and 3.13 (95% CI 1.43, 6.84; P less then 0.004), respectively. Conclusions The result of this meta-analysis suggests that female children, age over 10 years old, acute GVHD, hypertension, immunodeficiency, SCD, T-cell leukemia, and CNS leukemia/involvement are likely to have the poor outcome in pediatric oncologic/hematologic diseases in PRES.Background Research conducted in Western countries has suggested that high-dose statin therapy can lead to the regression of carotid atherosclerotic plaques and can reduce periprocedural ischemic complication rates in individuals undergoing carotid artery stenting (CAS). However, whether this same therapeutic approach is of value in patients of Chinese ethnicity is not as well-established. Methods This is a single-center, prospective, parallel-controlled, intervention-based efficacy study that will enroll a total of 130 Chinese patients with cervical carotid stenosis who are scheduled to undergo CAS. These patients will be randomly divided into a routine treatment group and a high-dose atorvastatin group. Individuals in the routine treatment group will be administered standard of care 20 mg/day atorvastatin treatment. Individuals in the high-dose atorvastatin group will be administered 80 mg/day atorvastatin for 3 days prior to and following CAS. The primary outcome of this study will be the cumulative incidence of new cerebral ischemic lesions on diffusion-weighted magnetic resonance imaging (DW-MRI) within 5 days following CAS, and of transient ischemic attacks (TIAs) or ischemic stroke within 30 days after CAS. Discussion This study is the first to assess whether high-dose atorvastatin treatment is capable of reducing the incidence of perioperative cerebral ischemic injury in patients of Chinese ethnicity undergoing CAS. These results will offer evidence regarding which statin treatment regimens are more appropriate when treating Chinese patients undergoing CAS in an effort to minimize their risk of any perioperative cerebral ischemic injury.

Previous research has found that anodal tDCS may enhance naming ability and verbal fluency in healthy participants. However, the effect of tDCS on more functional, higher level language skills such as discourse production has yet to be understood. Aims The present study aimed to investigate in healthy, older adults (a) the effect of anodal tDCS on discourse production vs. sham stimulation and (b) optimal electrode placement for tDCS to target language improvement at the discourse level. Methods Fourteen healthy, older right-handed participants took part in this sham controlled, repeated measures pilot study. Each participant experienced three different experimental conditions; anodal tDCS on the left inferior frontal gyrus (IFG), anodal tDCS on the right IFG and sham stimulation while performing a story telling task. Significant changes in language performance before and after each condition were examined in three discourse production tasks recount, procedural and narrative. Results Left and right IFG conditions showed a greater number of significant within-group improvements (p less then 0.05) in discourse production compared to sham with 6/12 for left IFG, 4/12 for right IFG and 2/12 for sham. There were no significant differences noted between tDCS conditions. No relationship was noted between language performance and physical activity, age, or gender. Conclusions This study suggests that anodal tDCS may significantly improve discourse production in healthy, older adults. In line with previous tDCS language studies, the left IFG is highlighted as an optimal stimulation site for the modulation of language in healthy speakers. The findings support further exploration of tDCS as a rehabilitative tool for higher-level language skills in persons with aphasia.This article addresses the potential clinical value of techniques based on surface electromyography (sEMG) in rehabilitation medicine with specific focus on neurorehabilitation. Applications in exercise and sport pathophysiology, in movement analysis, in ergonomics and occupational medicine, and in a number of related fields are also considered. EN450 The contrast between the extensive scientific literature in these fields and the limited clinical applications is discussed. The “barriers” between research findings and their application are very broad, and are longstanding, cultural, educational, and technical. Cultural barriers relate to the general acceptance and use of the concept of objective measurement in a clinical setting and its role in promoting Evidence Based Medicine. Wide differences between countries exist in appropriate training in the use of such quantitative measurements in general, and in electrical measurements in particular. These differences are manifest in training programs, in degrees granted, and in academic/research career opportunities.
