Pineal parenchymal tumor of intermediate differentiation (PPTID) is rare. The WHO first classified PPTID in 2000 as a pineal parenchymal tumor (PPT) with an intermediate prognosis between pineocytoma (PC) and pineoblastoma (PB). It is considered an intermediate-grade tumor and divided into WHO grade II or III.The number of available reports about PPTID is presently limited, and the appropriate management for this tumor has not yet been determined.The authors report a rare case of PC in a 63-year-old woman who presented with lower-extremity weakness and gait disturbance. A pineal mass lesion was detected on MRI. A diagnosis of PC was established after microsurgical gross-total tumor resection, and the patient received no adjuvant therapy after surgery. Two years after surgery, a partial recurrence was recognized and Gamma Knife radiosurgery was performed. Fours years later, the patient developed diffuse leptomeningeal dissemination. She was successfully treated with craniospinal irradiation. Leptomeningeal dissemination may develop 6 years after the initial diagnosis of PC. A histopathological study of the recurrent tumor revealed a malignant change from PC to PPTID.The present case shows the importance of long-term follow-up of patients with PPTs following resection and the efficacy of craniospinal irradiation in the treatment of leptomeningeal dissemination.

OBJECTIVEThe purpose of this study was to verify the safety and accuracy of the Neuromate stereotactic robot for use in deep brain stimulation (DBS) electrode implantation for the treatment of hyperkinetic movement disorders in childhood and describe the authors’ initial clinical results.METHODSA prospective evaluation of pediatric patients with dystonia and other hyperkinetic movement disorders was carried out during the 1st year after the start-up of a pediatric DBS unit in Barcelona. Electrodes were implanted bilaterally in the globus pallidus internus (GPi) using the Neuromate robot without the stereotactic frame. The authors calculated the distances between the electrodes and their respective planned trajectories, merging the postoperative CT with the preoperative plan using VoXim software. Clinical outcome was monitored using validated scales for dystonia and myoclonus preoperatively and at 1 month and 6 months postoperatively and by means of a quality-of-life questionnaire for children, administered before surgery and at 6 months’ follow-up. We also recorded complications derived from the implantation technique, “hardware,” and stimulation.RESULTSSix patients aged 7 to 16 years and diagnosed with isolated dystonia (DYT1 negative) (3 patients), choreo-dystonia related to PDE2A mutation (1 patient), or myoclonus-dystonia syndrome SGCE mutations (2 patients) were evaluated during a period of 6 to 19 months. The average accuracy in the placement of the electrodes was 1.24 mm at the target point. At the 6-month follow-up, patients showed an improvement in the motor (65%) and functional (48%) components of the Burke-Fahn-Marsden Dystonia Rating Scale. Patients with myoclonus and SGCE mutations also showed an improvement in action myoclonus (95%–100%) and in functional tests (50%–75%) according to the Unified Motor-Rating Scale. The Neuro-QOL score revealed inconsistent results, with improvement in motor function and social relationships but worsening in anxiety, cognitive function, and pain. The only surgical complication was medial displacement of the first electrode, which limited intensity of stimulation in the lower contacts, in one case.CONCLUSIONSThe Neuromate stereotactic robot is an accurate and safe tool for the placement of GPi electrodes in children with hyperkinetic movement disorders.
Performance of minimally invasive sagittal synostectomy with supine patient positioning: technical note
Authors: Martin Jonathan E. , Manning Thomas , Bookland Markus , Castiglione Charles 
Published: July 2018

OBJECTIVEMinimally invasive (MI) synostectomy with postoperative helmet orthosis is increasingly used in the management of sagittal craniosynostosis. Although the MI technique reduces or eliminates the need for access to the lateral skull surface, the modified prone/sphinx position remains popular. The authors present their initial experience with supine positioning for MI sagittal synostectomy.METHODSThe authors used supine positioning with the head turned laterally on a horseshoe head holder in 5 consecutive patients undergoing MI sagittal synostectomy.RESULTSResection of the sagittal suture from the anterior to posterior fontanel was accomplished in all patients. Surgical time averaged 70 minutes. No patient required transfusion. The posttreatment cephalic index averaged 83%.CONCLUSIONSInitial experience with supine positioning for MI sagittal synostectomy suggests that the technique can be used as an alternative to the modified prone position, with the potential to reduce anesthetic risk in these patients.

Published: July 2018

Background: Alzheimer-associated neuronal thread protein (AD7c-NTP) has been found to be a biomarker for Alzheimer’s disease (AD). Objective: The aim of the present study was to investigate the distribution of Alzheimer-associated neuronal thread protein and its relationship to common chronic diseases in the general population. Methods: Urine samples of 1,805 participants were collected from four districts (Xi Cheng, Fang Shan, Tong Zhou, and Yan Qing) in Beijing. The assessment in this study included a questionnaire that captured participants’ demographic information, use of medication and histories of disease, neurological examinations, psychometric evaluations, physical and clinical examinations, and laboratory tests. Results: Urine AD7c-NTP level was increased among the population over 60 years old and females exhibited higher levels than males. These results controlled for other demographic factors such as education levels, employment status, body mass index and current residence. The urine AD7c-NTP levels exhibited no association with non-neurological diseases (0.3346±0.4482 ng/ml), such as hypertension (0.3445±0.4187), stroke (0.3652±0.4010), diabetes (0.3319±0.4371), dyslipidemia (0.3440±0.4314), renal insufficiency (0.3223±0.3909), cancer (0.5055±1.0006), chronic lung disease (0.2911±0.2852), chronic liver disease (0.5579±0.6726), severe depression symptoms (0.5186±0.7040), and mild depression symptoms (0.3669±0.3811). Conclusions: Cut-off values for urine AD7c-NTP levels for different age groups and genders should be established. AD7c-NTP levels proved relatively stable in the body and were not impacted by demographic factors or common chronic diseases.

Published: July 2018

Background: Falls are common among people with idiopathic Parkinson’s disease (IPD) and are suggested to be associated with white matter hyperintensities (WMH) of the brain. Objective: To investigate the contribution of brain area-specific WMH to the risk of falls in IPD. Methods: In fifty participants with IPD, occurrence and severity of WMH in specific brain areas were determined using Scheltens (without lateralization) and Age-related white matter changes (ARWMC) (with lateralization) scores. Falls were evaluated with the fall item of the Unified PD Rating Scale (UPDRS). Correlations between area-specific WMH and falls were tested with stepwise backward regression and multivariate regression analyses. Results: In this cohort of participants with IPD, left temporal WMH were associated with occurrence of falls. Frontal WMH of both hemispheres showed tendencies towards significance for the association with falls. Conclusion: According to our study, WMH in the left temporal area are significantly associated with falls in IPD. Potential reasons for this association could be deficits in memory, navigation, orientation, auditory processing, and fear conditioning, which are all associated with pathologies of the left temporal lobe.
Transcranial direct current stimulation of the primary motor cortex on postoperative pain and spontaneous oscillatory electroencephalographic activity following lumbar spine surgery: A pilot study

Published: July 2018

Background: Transcranial direct current stimulation (tDCS) on primary motor cortex (M1) provides a new way to relieve postoperative pain. Previous studies only found postoperative analgesia dosage significantly reduced in tDCS group while the patient-controlled analgesia (PCA) was applied. However, there lacks the study about the effect of M1-tDCS on pain intensity and brain activity while the analgesia dosage is the same for both groups. Objective: To investigate whether M1-tDCS can (1) reduce pain intensity and (2) change spontaneous electroencephalography (EEG) oscillations in prefrontal cortex, in patients with postoperative pain, after taking the constant dosage of analgesics. Methods: A prospective, single-blind, randomized, sham-controlled study was conducted. 32 patients with postoperative pain after lumbar spine surgery were recruited. All patients received same dosage of dezocine before intervention. In the morning of the first day after surgery and before dezocine injection, a single 20-minute session of anodal M1-tDCS was applied to ‘tDCS’ group while sham stimulation to ‘sham’ group. Numeric rating scale (NRS) and resting-state EEG with eyes-closed were measured and analyzed. EEG spectral powers were analyzed using repeated measures analysis of variance (ANOVA). Correlation analysis was conducted between the change of NRS and the change of spectral power. Results: The NRS in “tDCS” group significantly decreased ( p < 0.01) while not in “sham” group after intervention. Only spectral power within alpha2 band (10–13 Hz) in Fp1 and beta1 band (13–20 Hz) in Fp1 showed significant Time×Intervention interaction effect. These changes of the spectral power also showed significant correlation with the change of NRS. Conclusions: The postoperative pain intensity in patients receiving surgery could reduce after a single session of anodal M1-tDCS compared to sham M1-tDCS. The effect to the top-down dimension of postoperative pain might account for the analgesic effect of M1-tDCS, which reflecting slow oscillations in left prefrontal EEG.

Abstract
We present the polarization pulse profiles for 28 pulsars observed with the Arecibo Observatory by the North American Nanohertz Observatory for Gravitational Waves timing project at 2.1 GHz, 1.4 GHz, and 430 MHz. These profiles represent some of the most sensitive polarimetric millisecond pulsar profiles to date, revealing the existence of microcomponents (that is, pulse components with peak intensities much lower than the total pulse peak intensity). Although microcomponents have been detected in some pulsars previously, we present microcomponents for PSR B1937+21, PSR J1713+0747, and PSR J2234+0944 for the first time. These microcomponents can have an impact on pulsar timing, geometry, and flux density determination. We present rotation measures for all 28 pulsars, determined independently at different observation frequencies and epochs, and find the Galactic magnetic fields derived from these rotation measures to be consistent with current models. These polarization profiles were made using measurement equation template matching, which allows us to generate the polarimetric response of the Arecibo Observatory on an epoch-by-epoch basis. We use this method to describe its time variability and find that the polarimetric responses of the Arecibo Observatory's 1.4 and 2.1 GHz receivers vary significantly with time.
Saturation Effect on Photoionization-driven Broad Absorption Line Variability
Authors: Lu 陆伟 Wei-Jian 坚 , Lin 林樱 Ying-Ru 如 
Published: July 2018

Abstract
We study the saturation effect on broad absorption line (BAL) variability through a variation phenomenon, which shows significant variation in Si iv BAL but no, or only small, change in C iv BAL (hereafter Phenomenon I). First, we explore a typical case showing Phenomenon I, quasar SDSS J153715.74+582933.9 (hereafter J1537+5829). We identify four narrow absorption line (NAL) systems within its Si iv BAL and two additional NAL systems within its C iv BAL, and confirm their coordinated weakening. Combining with the obvious strengthening of the ionizing continuum, we attribute the BAL variability in J1537+5829 to the ionization changes caused by the continuum variations. Second, a statistical study based on multiobserved quasars from SDSS-I/II/III are presented. We confirm that (1) the moderate anticorrelation between the fractional variations of Si iv BALs and the continuum in 74 quasars show Phenomenon I and (2) the sample showing BAL variations tends to have larger ionizing continuum variations. These results reveal the ubiquitous effect of the continuum variability on Phenomenon I and BAL variation. We attribute the relative lack of variation of C iv BALs in Phenomenon I to the saturation effects. Nonetheless, these absorbers are not very optically thick in Si iv and the ionization changes in response to continuum variations could be the main driver of their variations. Finally, we find that the saturation effect on BAL variability can explain many phenomena of BAL variations that have been reported before.
Galactic Planetary Nebulae as Probes of Radial Metallicity Gradients and Other Abundance Patterns
Authors: Stanghellini Letizia , Haywood Misha 
Published: July 2018

Abstract
We use planetary nebulae (PNe) as probes to determine the Galactic radial oxygen gradients and other abundance patterns. We select data homogeneously from recent data sets, including PNe at large Galactocentric distances. The radial oxygen gradient calculated for the general PN population, which probes the region from the Galactic center out to ∼28 kpc, is shallow, with slope ∼−0.02 dex kpc−1, in agreement with previous findings. We looked for time evolution of the metallicity gradient using PNe with different age progenitors as metallicity probes. We identify PNe whose progenitor stars are younger than 1 Gyr (YPPNe) and those whose progenitor stars are older than 7.5 Gyr (OPPNe) based on the comparison between evolutionary yields and elemental abundances of the PNe. By studying OPPNe and YPPNe separately, we found that (i) the OPPNe oxygen gradient is shallower (∼−0.015 dex kpc−1) than that derived from YPPNe (∼−0.027 dex kpc−1); (ii) the OPPNe inner radial distribution of oxygen is compatible with no gradient to the radial extent of the thick disk population (∼10 kpc), similarly to what has been observed in thick disk stars; and (iii) PNe (especially OPPNe) indicate that significant gradient slope is limited to Galactocentric distances between ∼10 and ∼13.5 kpc, as observed for open clusters and field stars. Outside this range, the distribution is almost flat. We found that the radial oxygen gradient is steeper for a PN population closer to the Galactic disk, similar to what is observed in the general stellar population by the SEGUE survey. We use our novel population dating to compare our results with current chemical evolutionary models and gradients from other Galactic populations for insight on galaxy chemical evolution.

Published: July 2018

Abstract
We present a new cosmological probe for galaxy clusters, the halo sparsity. This characterizes halos in terms of the ratio of halo masses measured at two different radii and carries cosmological information encoded in the halo mass profile. Building on the work of Balmes et al., we test the properties of the sparsity using halo catalogs from a numerical N-body simulation of (2.6 Gpc h
−1)3 volume with 40963 particles. We show that at a given redshift the average sparsity can be predicted from prior knowledge of the halo mass function. This provides a quantitative framework to infer cosmological parameter constraints using measurements of the sparsity of galaxy clusters. We show this point by performing a likelihood analysis of synthetic data sets with no systematics, from which we recover the input fiducial cosmology. We also perform a preliminary analysis of potential systematic errors and provide an estimate of the impact of baryonic effects on sparsity measurements. We evaluate the sparsity for a sample of 104 clusters with hydrostatic masses from X-ray observations and derive constraints on the cosmic matter density Ω
m

On the Variability of the Solar Mean Magnetic Field: Contributions from Various Magnetic Features on the Surface of the Sun
Authors: Bose Souvik , Nagaraju K. 
Published: July 2018

Abstract
The solar mean magnetic field (SMMF) is referred to as the disk-averaged line-of-sight (LOS) magnetic field that also reflects the polarity imbalance of the magnetic field on the Sun. The origin of the SMMF has been debated over the past few decades, with one school of thought suggesting that the contribution to the SMMF is mostly due to the large-scale magnetic field structure, also called the background magnetic field, whereas other and more recent studies have indicated that active regions have a major contribution to the observed SMMF. In this paper, we re-investigate the issue of the origin of the SMMF by decomposing the solar disk into plages, networks, sunspots, and background regions, thereby calculating the variation in the observed SMMF due to each of these features. We have used full-disk images from Solar Dynamics Observatory (SDO)/AIA recorded at 1600 Å for earmarking plages, networks, and background regions and 4500 Å images for separating the sunspots. The LOS fields corresponding to each of these regions are estimated from the co-temporal SDO/Helioseismic and Magnetic Imager full-disk magnetograms. The temporal variation of the SMMF shows a near one-to-one correspondence with that of the background field regions, suggesting that they constitute the major component of the observed SMMF. A linear regression analysis based on the coefficient of determination shows that the background field dominates and accounts for 89% of the variation in the SMMF, whereas the magnetic field from the other features accounts for the rest 11%.
