    ABSTRACT: Monoamine systems are involved in the pathology and therapeutic mechanism of depression. The pineal gland contains large amounts of serotonin as a precursor for melatonin, and its activity is controlled by noradrenergic sympathetic nerves. Pineal diurnal activity and its release of melatonin are relevant to aberrant states observed in depression. We investigated the effects on pineal monoamines of serotonin-noradrenaline reuptake inhibitors, which are widely used antidepressants. Four days of milnacipran treatment led to an increase in noradrenaline and serotonin levels, whereas 4 days of venlafaxine treatment reduced 5-hydroxyindoleacetic acid levels; both agents induced an increase in dopamine levels. Our data suggest that milnacipran increases levels of the precursor for melatonin synthesis by facilitating the noradrenergic regulation of pineal activity and that venlafaxine inhibits serotonin reuptake into noradrenergic terminals on the pineal gland.

    ABSTRACT: This study reports on a 9-year-old girl who developed West syndrome and showed clinical features fulfilling the main revised diagnostic criteria for typical Rett syndrome (hand washing, severe cognitive impairment with absence of language, ataxic gait, progressive scoliosis and autistic features). Mutation analyses for methyl-CpG-binding protein 2 (MECP2), cyclin-dependent kinase-like 5 (CDKL5/STK9), ARX and Forkhead box G1 (FOXG1) genes were carried out, with negative results. A known de-novo c.1217G>A missense mutation in exon 14 leading to the substitution of a conserved residue, p.R406H in domain3b of the syntaxin-binding protein 1 (STXBP1) gene, was detected. The STXBP1 gene encodes the syntaxin-binding protein 1, a neuron-specific protein involved in synaptic vesicle release at both glutaminergic and GABAergic synapses. This function is also affected by MECP2 gene mutations, which are known to lead to a decrease in glutamate and GABA receptors' density. It is possible to speculate that the impairment in synaptic plasticity represents the pathogenic link between MECP2 and STXBP1 gene mutations. On reviewing the clinical features of the reported patients with the same mutation in the STXBP1 gene, it has been observed that poor eye contact, tremour, dyskinesia, head/hand stereotypies and both cognitive and motor progressive deterioration are common symptoms, although never considered as indicative of a Rett syndrome phenotype. In conclusion, the case described here suggests a relationship between the Rett syndrome and the STXBP1 gene not described so far, making the search for STXBP1 gene mutations advisable in patients with Rett syndrome and early onset of epilepsy.

    ABSTRACT: Attempts to identify physiological correlates of listening effort have mainly focused on peripheral measures (e.g. pupillometry) and auditory-evoked/event-related potentials. Although nonauditory studies have suggested that sustained time-frequency electroencephalographic (EEG) features in the θ-band (4-7 Hz) are correlated with domain-general mental effort, little work has characterized such features during effortful listening. Here, high-density EEG data was collected while listeners performed a sentence-recognition task in noise, the signal-to-noise ratio (SNR) of which varied across blocks. Frontal midline θ (Fmθ), largely driven by sources localized in or near the medial frontal cortex, showed greater power with decreasing SNR and was positively correlated with self-reports of effort. Increased Fmθ was present before speech onset and during speech presentation. Fmθ power also differed across SNRs when including only trials in which all words were recognized, suggesting that the effects were unrelated to performance differences. Results suggest that frontal cortical networks play a larger role in listening as acoustic signals are increasingly masked. Further, sustained time-frequency EEG features may usefully supplement previously used peripheral and event-related potential measures in psychophysiological investigations of effortful listening.

    ABSTRACT: Intracranial hemorrhages are associated with high rates of disability and mortality. Telemedicine in general provides clinical healthcare at a distance by using videotelephony and teleradiology and is used particularly in acute stroke care medicine (TeleStroke). TeleStroke considerably improves quality of stroke care (for instance, by increasing thrombolysis) and may be valuable for the management of intracranial hemorrhages in rural hospitals and hospitals lacking neurosurgical departments, given that surgical/interventional therapy is only recommended for a subgroup of patients. The aim of this study was to analyze the frequency, anatomical locations of intracranial hemorrhage, risk factors, and the proportion of patients transferred to specialized hospitals. We evaluated teleconsultations conducted between 2008 and 2010 in a large cohort of patients consecutively enrolled in the Telemedical Project for Integrated Stroke Care (TEMPiS) network. In cases in which intracranial hemorrhage was detected, all images were re-examined and analyzed with a focus on frequency, location, risk factors, and further management. Overall, 6187 patients presented with stroke-like symptoms. Intracranial hemorrhages were identified in 631 patients (10.2%). Of these, intracerebral hemorrhages were found in 423 cases (67.0%), including 174 (41.1%) in atypical locations and 227 (53.7%) in typical sites among other locations. After 14 days of hospitalization in community facilities, the mortality rate in patients with intracranial hemorrhages was 15.1% (95/631). Two hundred and twenty-three patients (35.3%) were transferred to neurological/neurosurgical hospitals for diagnostic workup or additional treatment. Community hospitals are confronted with patients with intracranial hemorrhage, whose management requires specific neurosurgical and hematological expertise with respect to hemorrhage subtype and clinical presentation. TeleStroke networks help select patients who need advanced neurological and/or neurosurgical care. The relatively low proportion of interhospital transfers shown in this study reflects a differentiated decision process on the basis of both guidelines and standard operating procedures.

    ABSTRACT: It has been reported that inhibition of sirtuin 2 (SIRT2), a sirtuin family protein, can decrease cellular and tissue injuries in models of Parkinson's disease (PD) and Huntington's disease (HD); however, the mechanisms underlying these observations have remained unclear. Because inflammation plays key pathological roles in multiple major neurological disorders including PD and HD, in our current study we tested our hypothesis that SIRT2 plays an important role in microglial activation. We found that treatment of BV2 microglia with lipopolysaccharides led to significant increases in NO and inducible nitric oxide synthase mRNA levels, as well as increases in the levels of tumor necrosis factor-α and interleukin 6 mRNA, which indicated microglial activation. These increases were significantly decreased in the cells with SIRT2 silencing-produced decreases in the SIRT2 level. These observations suggest that SIRT2 is required for lipopolysaccharide-induced microglial activation. The findings also suggest that SIRT2 may be a therapeutic target for inhibiting the inflammatory responses in neurological disorders such as PD and HD.

    ABSTRACT: The aim of the study was to assess the relationship between procalcitonin (PCT) serum levels and acute ischemic stroke (AIS) in a Chinese sample. All consecutive patients with first-ever AIS between January 2012 and December 2013 were recruited to participate in the study. PCT levels and National Institutes of Health Stroke Scale scores were evaluated at the time of admission. Logistic regression analysis was used to evaluate the risk for stroke according to serum PCT levels. The results indicated that serum PCT levels were significantly higher in AIS patients as compared with normal controls (P<0.0001). PCT levels increased with increasing severity of stroke, as defined by the National Institutes of Health Stroke Scale score. After adjusting for all other possible covariates, PCT level was found to be associated with an increased risk for AIS, with an adjusted odds ratio of 2.244 (95% confidence interval 1.563-3.756, P<0.0001). On the basis of the receiver operating characteristic curve, the optimal cutoff value of serum PCT levels as an indicator for auxiliary diagnosis of AIS was projected to be 1.20 ng/ml, which yielded a sensitivity of 79.6% and a specificity of 72.1%, with the area under the curve at 0.801 (95% confidence interval 0.762-0.844). An elevated serum level of PCT was a novel, independent diagnostic marker of AIS in the Chinese sample. Further study is needed to confirm these results.

    ABSTRACT: Late preterm birth is increasingly recognized as a risk factor for cognitive and social deficits. The prefrontal cortex is particularly vulnerable to injury in late prematurity because of its protracted development and extensive cortical connections. Our study examined children born late preterm without access to advanced postnatal care to assess structural and functional connectivity related to the prefrontal cortex. Thirty-eight preadolescents [19 born late preterm (34-36 /7 weeks gestational age) and 19 at term] were recruited from a developing community in Brazil. Participants underwent neuropsychological testing. Individuals underwent three-dimensional T1-weighted, diffusion-weighted, and resting state functional MRI. Probabilistic tractography and functional connectivity analyses were carried out using unilateral seeds combining the medial prefrontal cortex and the anterior cingulate cortex. Late preterm children showed increased functional connectivity within regions of the default mode, salience, and central-executive networks from both right and left frontal cortex seeds. Decreased functional connectivity was observed within the right parahippocampal region from left frontal seeding. Probabilistic tractography showed a pattern of decreased streamlines in frontal white matter pathways and the corpus callosum, but also increased streamlines in the left orbitofrontal white matter and the right frontal white matter when seeded from the right. Late preterm children and term control children scored similarly on neuropsychological testing. Prefrontal cortical connectivity is altered in late prematurity, with hyperconnectivity observed in key resting state networks in the absence of neuropsychological deficits. Abnormal structural connectivity indicated by probabilistic tractography suggests subtle changes in white matter development, implying disruption of normal maturation during the late gestational period.

    ABSTRACT: Early life stress is a risk factor for developing functional pain disorders. The 'limited bedding' (LB) model elicits psychological stress in the dam and her pups by providing minimal nesting material following delivery. Little is known about the effects of LB on visceral pain. Rats (female, male) were exposed to LB on postnatal days 2-9. Electromyographic visceromotor responses were recorded at the age of 11-12 weeks during titrated colorectal distension. LB exposure resulted in significant visceral hyperalgesia in both sexes. Sex differences were demonstrated only in nonstressed controls, with females showing a greater visceromotor response. Our results prepare the way for use of the LB model in studying the development of visceral pain in adults with functional gastrointestinal disorders.

    ABSTRACT: Bell's palsy (BP), a unilateral and idiopathic palsy of the facial nerve, is a common disorder generally followed by a good natural recovery. The aim of this study was to investigate the relationship between the functional connectivity of the anterior cingulate cortex (ACC) and the recovery process of BP. Thirty-seven healthy volunteers and 67 patients were studied by functional MRI (fMRI). The seed regions of bilateral ACC were first extracted from the task-state fMRI data of healthy participants performing the task of mouth opening and closing. The connectivity of bilateral ACC was calculated from resting-state fMRI data of patients in whom only resting-state fMRI data were collected. The correlation between the strength of ACC's connectivity with the duration (time course of disease) was computed by analysis of covariance. It was found that the functional connectivity of the ACC ipsilateral to the lesioned side was enforced as the duration increased. The enforced brain areas included the sensorimotor areas and the ACC contralateral to the palsy. It was suggested that enforced functional connectivity of ACC might be related to cortical reorganization, which is important in the process of BP recovery.

    ABSTRACT: Neuropsychiatric systemic lupus erythematosus (NPSLE) is speculated to be caused by disturbed microcirculation of the central nervous system. However, characteristic imaging findings of NPSLE have not been established. Hence, we investigated whether high-resolution images obtained using ultrahigh field MRI at 7 T can detect microcerebrovascular lesions in patients with NPSLE that have never been detected by conventional MRI. We prospectively examined 20 patients with SLE, including five with NPSLE, using a 7 T MRI scanner. High-resolution two-dimensional T2-weighted images and high-resolution three-dimensional T1-weighted images (T1WIs) before and after the administration of contrast agents were obtained. On the high-resolution T1WIs obtained at 7 T, minute punctate/linear hyperintense lesions in subcortical and/or cortical areas were found in four (80%) NPSLE patients and one (7%) non-NPSLE patient. Further, the minute punctate enhanced lesions in these areas were found on contrast-enhanced T1WIs in only three (60%) NPSLE patients. These findings suggesting microvascular thrombi or inflammation were significantly more frequent in NPSLE than in non-NPSLE patients (P=0.001). In contrast, other imaging findings, laboratory findings, and clinical characteristics were not different between the two groups. High-resolution T1WIs obtained at 7 T can detect minute lesions, indicating intracerebral microvascular lesions in patients with NPSLE.

    ABSTRACT: During hunting, insectivorous bats systematically vary the parameters of emitted pulses and analyze the returning echoes to extract prey features. As such, the duration of the pulse (P) and echo (E), the P-E gap, and the P-E amplitude difference progressively decrease throughout the prey-approach sequence. Our previous studies have shown that most inferior collicular neurons of bats discharge maximally to a best duration, and they have the sharpest echo frequency and amplitude sensitivity when stimulated with P-E pairs with duration the same as the best duration. Furthermore, their echo duration and frequency sensitivity improves with decreasing P-E duration and P-E gap. The present study shows that this is also true in the amplitude domain. Thus, all these data indicate that bats can better extract multiple parameters of expected rather than unexpected echo after pulse emission. They also support the hypothesis that a bat's inferior collicular neurons improve the response sensitivity in multiple parametric domains as the prey is approached to increase the success of hunting.

    ABSTRACT: To evaluate the association between plasma levels of copeptin and 1-year mortality in a cohort of Chinese patients with acute ischemic stroke. We prospectively studied 275 patients with ischemic stroke who were admitted within 24 h after the onset of symptoms. Copeptin and NIH stroke scale (NIHSS) score were measured at the time of admission. The prognostic value of copeptin to predict mortality within 1 year was compared with the NIHSS score and other known outcome predictors. Nonsurvivors had significantly higher copeptin levels on admission compared with survivors (P<0.0001). Multivariate logistic regression analysis showed that elevated plasma levels of copeptin were an independent stroke mortality predictor, with an adjusted odds ratio of 4.48 [95% confidence interval (CI), 2.18-9.06]. The area under the receiver operating characteristic curve of copeptin was 0.882 (95% CI, 0.847-0.921) for stroke mortality, which yielded a sensitivity of 90.7% and a specificity of 84.5%. Copeptin improved the NIHSS score (area under the curve of the combined model, 0.94; 95% CI, 0.91-0.97; P=0.011). Elevated plasma copeptin levels at admission were an independent predictor of long-term mortality after ischemic stroke in a Chinese sample, suggesting that these alterations might play a role in the pathophysiology of stroke.

    ABSTRACT: To observe changes in mismatch negativity (MMN) and P300 in a patient transitioning from a vegetative state (VS) to a minimally conscious state (MCS). One patient with intracerebral hemorrhage and an 8-month disease course was evaluated as being in the VS using the Coma Recovery Scale-Revised. Two weeks after the patient was admitted to the hospital, another evaluation was performed, and the patient was determined to be in an MCS. Using the Oddball paradigm, pure tone and name stimuli were presented to the patient to study event-related potentials (ERPs). A 15-week clinical follow-up was carried out, and four ERP examinations were performed at 2 days and 2, 6, and 15 weeks after admission. One healthy individual was assessed as a control participant. MMN and P300 were elicited in all four ERP examinations. MMN and P300 may occur earlier than believed in patients in persistent VS and MCS; their predictive values for prognosis need to be further confirmed by follow-up studies on a large clinical sample.This is an open-access article distributed under the terms of the Creative Commons Attribution-NonCommercial-NoDerivatives 3.0 License, where it is permissible to download and share the work provided it is properly cited.
