Our findings do not exclude a role of endotoxin in mediating signals from the gut microbiota in MS patients directly at the gut-blood barrier where numerous antigen-presenting cells are actively sensing metabolites and bacterial products.Background and Purpose As a rare lesion secondary to brain trauma, traumatic intracranial aneurysms (TICAs) lead to high mortality and morbidity, and multiple treatment modalities have been applied for TICAs. All patients diagnosed with TICAs in our institution from 2010 to 2020 were included in the report, and their clinical features, treatment, and outcomes are described in detail. The purpose of this study is to illustrate the characteristic of different therapeutic methods of TICAs, and focus on the endovascular treatment. Methods A total of 20 patients were included in this study. The 3 patients who declined treatment all died. Five of the other 17 patients were treated surgically, including clipping, wrapping, and trapping with or without EC-IC high-flow bypass, with only 1 case of parent artery preservation. Twelve patients underwent endovascular treatment, including bare coil embolization (1 case), stent-assisted coiling (2 cases), balloon-assisted coils/Onyx glue embolization (1 case) and covered stet has emerged as a valuable option, which may be promising to improve the clinical outcomes due to their advantages of preserving the parent artery if occlusion of the side branch artery can be avoided.Introduction Diagnosis of Guillain Barre syndrome (GBS) is often made clinically. Certain patient and disease characteristics can cause delays in diagnosis and management. Methods Observational retrospective study of forty-four patients diagnosed with GBS either clinically, cerebrospinal fluid analysis, and/or by electro-diagnostic criteria at a teaching hospital (University of Missouri Hospital) in Columbia, Mid-Missouri between 2011 and 2017. Results Patients with coexisting neurological conditions had statistically significant delay in diagnosis of GBS [Mean (SD); 13 ± 5 vs. 9.39 ± 4.7; p = 0.03]. Patients presenting with motor + symptoms (sensory and/or autonomic, in addition to motor), compared to those with only motor symptoms had statistically significant delay in diagnosis of GBS [Mean (SD); 11.90 ± 5 vs. 8.58 ± 4; p = 0.04]. Discussion Presence of co-existing neurological conditions, and motor + symptoms can delay timely diagnosis and management of GBS.The mechanism of epileptic spasms (ES) in Aicardi syndrome (AS) remains obscure. We compared intraoperative high-frequency oscillations (HFOs) and phase-amplitude coupling (PAC) before and after subtotal hemispherotomy in a 3-month-old girl with drug-resistant ES secondary to AS. Fetal ultrasonography showing corpus callosum agenesis, bilateral ventricular dilatation, and a large choroid plexus cyst confirmed AS diagnosis. Her ES started when she was 1 month old and had ten series of clustered ES per day despite phenobarbital and vitamin B6 treatment. After subtotal hemispherotomy, her ES dramatically improved. We analyzed two intraoperative electrocorticography modalities (1), occurrence rate (OR) of HFOs; (2), PAC of HFOs and slow wave bands in the frontal, central, and parietal areas. We hypothesized that HFOs and PAC could be the biomarkers for efficacy of subtotal hemispherotomy in AS with ES. PAC in all three areas and OR of HFOs in the frontal and parietal areas significantly decreased, while OR of HFOs in the central area remained unchanged after subtotal hemispherotomy. We have demonstrated the usefulness of evaluating intraoperative HFOs and PAC to assess subtotal hemispherotomy effectiveness in AS patients with ES. Disconnecting the thalamocortical and subcortical pathways in the epileptic network plays a role in controlling ES generation.Background Concussion symptoms in adolescents typically resolve within 4 weeks. However, 20 - 30% of adolescents experience a prolonged recovery. Abnormalities in tracts implicated in visuospatial attention and emotional regulation (i.e., inferior longitudinal fasciculus, ILF; inferior fronto-occipital fasciculus, IFOF; uncinate fasciculus; UF) have been consistently reported in concussion; yet, to date, there are no objective markers of prolonged recovery in adolescents. Here, we evaluated the utility of diffusion MRI in outcome prediction. Forty-two adolescents (12.1 - 17.9 years; female 44.0%) underwent a diffusion Magnetic Resonance Imaging (dMRI) protocol within the first 10 days of concussion. Based on days of injury until medical clearance, adolescents were then categorized into SHORT (28 days; N = 21) recovery time. Fractional anisotropy (FA) in the ILF, IFOF, UF, and/or concussion symptoms were used as predictors of recovery time (SHORT, LONG). Forty-two age- and sex-matched healthy controls served as reference. Higher FA in the ILF (left adjusted odds ratio; AOR = 0.36, 95% CI = 0.15 - 0.91, P = 0.030; right AOR = 0.28, 95% CI = 0.10 - 0.83, P = 0.021), IFOF (left AOR = 0.21, 95% CI = 0.07 - 0.66, P = 0.008; right AOR = 0.30, 95% CI = 0.11 - 0.83, P = 0.020), and UF (left AOR = 0.26, 95% CI = 0.09 - 0.74, P = 0.011; right AOR = 0.28, 95% CI = 0.10 - 0.73, P = 0.010) was associated with SHORT recovery. In additional analyses, while adolescents with SHORT recovery did not differ from HC, those with LONG recovery showed lower FA in the ILF and IFOF (P less then 0.014). Notably, inclusion of dMRI findings increased the sensitivity and specificity (AUC = 0.93) of a prediction model including clinical variables only (AUC = 0.75). Our findings indicate that higher FA in long associative tracts (especially ILF) might inform a more objective and accurate prognosis for recovery time in adolescents following concussion.Sleepwalking has been conceptualized as deregulation between slow-wave sleep and arousal, with its occurrence in predisposed patients increasing following sleep deprivation. Recent evidence showed autonomic changes before arousals and somnambulistic episodes, suggesting that autonomic dysfunctions may contribute to the pathophysiology of sleepwalking. We investigated cardiac autonomic modulation during slow-wave sleep in sleepwalkers and controls during normal and recovery sleep following sleep deprivation. Fourteen adult sleepwalkers (5M; 28.1 ± 5.8 years) and 14 sex- and age-matched normal controls were evaluated by video-polysomnography for one baseline night and during recovery sleep following 25 h of sleep deprivation. Autonomic modulation was investigated with heart rate variability during participants' slow-wave sleep in their first and second sleep cycles.  https://www.selleckchem.com/products/capsazepine.html  5-min electrocardiographic segments from slow-wave sleep were analyzed to investigate low-frequency (LF) and high-frequency (HF) components of heart rate spectral decomposition.
