Associations of Anemia With Outcomes in Patients With Spontaneous Intracerebral Hemorrhage: A Meta-Analysis
Conclusions: Anemia on admission was associated with higher mortality and an increased risk of poor outcome in patients with ICH. However, the results were limited by the high heterogeneity of included studies. Prospective, multi-center or population-based, large sample cohort studies are needed in the future. Introduction Intracerebral hemorrhage (ICH) is the second most common cause of stroke and a highly lethal disease (1), which still lacks effective therapeutic interventions (2, 3). Although age, baseline ICH volume and neurological status on admission are well-known predictors of outcome of ICH (4), none of t...

Clinical Imaging Findings of Vestibular Aqueduct Trauma in a Patient With Posttraumatic Meniere's Syndrome
In conclusion, for the radiological assessment of TB fractures, the entire VA should be regarded as a part of the otic capsule, and delayed inner ear sequelae should be anticipated for retrolabyrinthine fracture lines that course into or through the VA. When considering treatment options in cases similar to the present, our findings suggest that surgical interventions targeting the eES (ES shunting/decompression procedures (31–33), which are used in MD with the intention to drain the hydropic endolymphatic fluid space, or to improve the fluid resorptive functions of the eES, respectively, most likely cannot work as p...

The Predictive Capacity of the Buffalo Concussion Treadmill Test After Sport-Related Concussion in Adolescents
In this study, we assessed the relationship of ΔHR (difference between resting HR and HRt) and recovery from SRC. Using a retrospective cohort design, we compared acutely (30 days) in RG (p = 0.01) and PG (p = 0.04). A ΔHR of ≤50 bpm on the BCTT is 73% sensitive and 78% specific for predicting prolonged recovery in concussed adolescents who were prescribed the current standard of care (i.e., cognitive and physical rest).

Conclusions: To our knowledge, this is the first study to investigate VS-related tinnitus with respect to both patients' hearing status and psychological condition. Our results suggest that tinnitus distress strongly affects VS patients' QoL and that its characteristics are similar to primary tinnitus.

Conclusion This systematic review provides an update on GI-APA reorganization following stroke. Stroke patients present atypical GI-APA patterns, longer GI-APA duration and lower GI-APA amplitude compared to healthy people, regardless of which leg is used as the leading or trailing leg. GI is facilitated when the non-paretic leg is used as the trailing leg because the weakness of the paretic leg leads to difficulties in supporting body weight during the upcoming stance phase.

Corticospinal Tract Integrity and Long-Term Hand Function Prognosis in Patients With Stroke
Conclusions: The present study showed that CST integrity (at 6 months after onset) in patients with chronic stroke was related to functional hand status. In addition, the mid-pons FA value was more predictive of functional restoration of the hand than the FN or FA value at the pontomedullary junction. These results may be useful in predicting the functional restoration of the hand and understanding the functional prognosis of stroke. Introduction Restoration of hand function is one of the most important goals for patients with stroke (1). Thus, techniques that aid in predicting restoration of hand function are also i...

Potential Utility of 123I-MIBG Scintigraphy as a Predictor of Falls in Parkinson's Disease
Conclusions: Although the limitations of this study were lack of several key factors including motor and cognitive assessment, MIBG cardiac scintigraphy may be used to predict falls in patients with PD. Introduction Falls predict an unfavorable prognosis due to poor motor function in patients with Parkinson's disease (PD), which are attributed to considerable factors including motor and non-motor impairments (1). Although it is not easy to overcome falls, several interventions have been developed. These include administration of acetylcholinesterase inhibitors (2) or the prodrug of epinephrine (3), and Tai ...

A Novel RNF139 Mutation in Hemangioblastomas: Case Report
This report supports that the novel mutation of RNF139 p.Q650R probably serve as a key role in HBs progression. Introduction Central nervous system hemangioblastomas (HBs) are benign tumors which usually occur in cerebellum (1), and the pathogenesis of HBs is still unknown. According to the revised World Health Organization (WHO) classification of tumors of the nervous system published in 2000, HBs were classified to the tumors of uncertain histogenesis. The morphology code of the International Classification of Diseases for Oncology (ICD-O)is 9161/1, grade I. HBs are composed of mesenchymal cells and abundant capi...

Spinal Cord Imaging in Amyotrophic Lateral Sclerosis: Historical Concepts —Novel Techniques
Conclusions The momentous advances in spinal imaging in ALS suggest the spinal metrics may soon be used as validated diagnostic, monitoring, and prognostic markers, contributing both to individualized patient care and pharmacological trials. Author Contributions ME, GQ, PB, and P-FP contributed equally to the conceptualization, drafting, and revision of the manuscript.
