Published: July 2018

Background: Increasing the cross sectional area (CSA) of the left internal jugular vein facilitates cannulation and decreases complications. But, the literature is sparse regarding the methods to increase the cross sectional area of the left internal jugular vein.Objective: To assess the changes that occur in cross sectional area of left internal jugular vein after application of different levels of positive end expiratory pressure and compare the findings with right internal jugular vein.Methodology: Sixty-four patients were included. Antero posterior diameter, transverse diameter and cross sectional area of left and right internal jugular vein was measured using two-dimensional ultrasound before the induction of anesthesia and after intubation at positive end expiratory pressure of 0, 5, 10 and 15 cm H2O. Result: The increase in positive end expiratory pressure was associated with increase in cross sectional area, anteroposterior and transverse diameter of left internal jugular vein. At 10 cmH2 Opositive end expiratory pressure, left internal jugular vein cross sectional area increased significantly by 22.8% that is 1.34±0.53cm2(P value< 0.05). The right internal jugular vein is significantly larger than left at baseline and at all levels of studied positive end expiratory pressure. The percentage increase of cross sectional area for both internal jugular veins was similar.Conclusion: The left internal jugular vein cross sectional area increment has direct relationship with increment of positive end expiratory levels at studied points. However, above 10 cm H2O of positive end expiratory pressure, there was only non significant increase (P value > 0.05).

Published: July 2018

OBJECTIVEIn WHO grade II low-grade gliomas (LGGs), early postoperative MRI (epMRI) may overestimate residual tumor on FLAIR sequences. Consequently, MRI at 3–6 months follow-up (fuMRI) is used for delineation of residual tumor. This study sought to evaluate if integration of apparent diffusion coefficient (ADC) maps permits an accurate estimation of residual tumor early on epMRI.METHODSFrom a consecutive cohort, 43 cases with an initial surgery for an LGG, and complete epMRI (< 72 hours after resection) and fuMRI including ADC maps, were retrospectively identified. Residual FLAIR hyperintense tumor was manually segmented on epMRI and corresponding ADC maps were coregistered. Using an expectation maximization algorithm, residual tumor segments were probabilistically clustered into areas of residual tumor, ischemia, or normal white matter (NWM) by fitting a mixture model of superimposed Gaussian curves to the ADC histogram. Tumor volumes from epMRI, clustering, and fuMRI were statistically compared and agreement analysis was performed.RESULTSMean FLAIR hyperintensity suggesting residual tumor was significantly larger on epMRI compared to fuMRI (19.4 ± 16.5 ml vs 8.4 ± 10.2 ml, p < 0.0001). Probabilistic clustering of corresponding ADC histograms on epMRI identified subsegments that were interpreted as mean residual tumor (7.6 ± 10.2 ml), ischemia (8.1 ± 5.9 ml), and NWM (3.7 ± 4.9 ml). Therefore, mean tumor quantification error between epMRI and fuMRI was significantly reduced (11.0 ± 10.6 ml vs −0.8 ± 3.7 ml, p < 0.0001). Mean clustered tumor volumes on epMRI were no longer significantly different from the fuMRI reference (7.6 ± 10.2 ml vs 8.4 ± 10.2 ml, p = 0.16). Correlation (Pearson r = 0.96, p < 0.0001), concordance correlation coefficient (0.89, 95% confidence interval 0.83), and Bland-Altman analysis suggested strong agreement between both measures after clustering.CONCLUSIONSProbabilistic segmentation of ADC maps facilitates accurate assessment of residual tumor within 72 hours after LGG resection. Multiparametric image analysis detected FLAIR signal alterations attributable to surgical trauma, which led to overestimation of residual LGG on epMRI compared to fuMRI. The prognostic value and clinical impact of this method has to be evaluated in larger case series in the future.

Published: July 2018

OBJECTIVEThe goal of this study was to describe changes in the angioarchitecture of brain arteriovenous malformations (bAVMs) between acute and delayed cerebral digital subtraction angiography (DSA) obtained after hemorrhage, and to examine bAVM characteristics predicting change.METHODSThis is a retrospective study of a prospective institutional bAVM database. The authors included all patients with ruptured bAVMs who had DSA in both acute and delayed phases, with no interval treatment of their bAVM, between January 2000 and April 2017. The authors evaluated the existence or absence of angioarchitectural changes. Demographic data, radiological characteristics of hemorrhages, and angioarchitectural features of the bAVMs of the two patients’ groups were analyzed. Univariate and multivariate logistic analyses were performed to identify predictors of angioarchitectural change.RESULTSA total of 42 patients were included in the series. Seventeen (40.5%) patients had angioarchitectural changes including bAVM only visible on the delayed DSA study (n = 8), spontaneous thrombosis of the AVM (n = 3), or alteration of the size or the opacification of the nidus (n = 6). The factors associated with angioarchitectural changes were a small nidus (3.8 ± 7.9 ml vs 6.1 ± 9.5 ml, p = 0.046), a superficial location (94.1% vs 5.9%, p = 0.016), and a single superficial draining vein (58.8% vs 24.0%, p = 0.029).CONCLUSIONSAngioarchitectural changes can be seen in 40% of ruptured bAVMs between the acute- and delayed-phase DSA. A small nidus, a superficial location, and a single superficial draining vein were statistically associated with the occurrence of angioarchitectural changes. These changes included either enlargement or spontaneous occlusion of the bAVM, as well as subsequent diagnosis of a bAVM following an initial negative DSA study.

OBJECTIVEThis nationwide study was organized to evaluate the clinical characteristics, especially the annual detected rate, of pediatric intracranial arteriovenous (AV) shunts such as brain AV malformations (BAVMs), pial AV fistulas (PAVFs), vein of Galen aneurysmal malformations (VGAMs), and dural AV fistulas (DAVFs) in Japan.METHODSParticipation invitation emails for the study were sent to all members of the Japanese Society for Neuroendovascular Therapy and the Japanese Society for Pediatric Neurosurgery, totaling 4123 physicians. Excel files were attached to the emails to collect clinical data on patients aged 5 years old or younger with intracranial AV shunts at each hospital in the 5-year period from 2012 to 2016.RESULTSRepresentative physicians from 209 hospitals returned Excel files containing the patient data. Thirty-four hospitals reported on 72 patients with intracranial AV shunts. Among this cohort, 24 patients (33%) had BAVMs, 22 (31%) had PAVFs, 16 (22%) had VGAMs, and 10 (14%) had DAVFs. Male predominance (70%) was observed among all types of AV shunts. Most PAVFs (73%), VGAMs (88%), and DAVFs (100%) were diagnosed in patients younger than 1 year, especially neonates, whereas most BAVMs (92%) were diagnosed in children older than 1 year. In the patients older than 1 year, BAVMs were relatively common, and VGAMs and DAVFs were rare.CONCLUSIONSThe annual detected rates of BAVMs, PAVFs, VGAMs, and DAVFs in patients 5 years old or younger were 0.0775, 0.0710, 0.0517, and 0.0323 per 100,000 persons, respectively. In neonates and infants, VGAM, DAVF, and PAVF were relatively common, but BAVMs were extremely rare.

A WISE Survey of Circumstellar Disks in the Upper Scorpius Association*
Authors: Esplin T. L. , Luhman K. L. , Miller E. B. , Mamajek E. E. 
Published: July 2018

Abstract
We have performed a survey for new members of the Upper Sco association that have circumstellar disks using mid-infrared photometry from the Wide-field Infrared Survey Explorer (WISE). Through optical and near-infrared spectroscopy, we have confirmed 185 candidates as likely members of Upper Sco with spectral types ranging from mid-K to M9. They comprise ∼36% of the known disk-bearing members of the association. We also have compiled all available mid-infrared photometry from WISE and the Spitzer Space Telescope for the known members of Upper Sco, resulting in a catalog of data for 1608 objects. We have used these data to identify the members that exhibit excess emission from disks and we have classified the evolutionary stages of those disks with criteria similar to those applied in our previous studies of Taurus and Upper Sco. Among 484 members with excesses in at least one band (excluding five Be stars), we classify 296 disks as full, 66 as evolved, 19 as transitional, 22 as evolved or transitional, and 81 as evolved transitional or debris. Many of these disks have not been previously reported, including 129 full disks and 50 disks that are at more advanced evolutionary stages.
Feasibility of a Resonance-based Planet Nine Search
Authors: Bailey Elizabeth , Brown Michael E. , Batygin Konstantin 
Published: July 2018

Abstract
It has been proposed that mean-motion resonances (MMRs) between Planet Nine and distant objects of the scattered disk might inform the semimajor axis and instantaneous position of Planet Nine. Within the context of this hypothesis, the specific distribution of occupied MMRs largely determines the available constraints. Here we characterize the behavior of scattered Kuiper Belt objects arising in the presence of an eccentric Planet Nine (e
9 ∈ 0.1, 0.7), focusing on relative sizes of populations occupying particular commensurabilities. Highlighting the challenge of predicting the exact MMR of a given object, we find that the majority of resonant test particles have period ratios with Planet Nine other than those of the form P
9/P = N/1, N/2

. Taking into account the updated prior distribution of MMRs outlined in this work, we find that the close spacing of high-order resonances, as well as chaotic transport, preclude resonance-based Planet Nine constraints from current observational data.

Published: July 2018

Abstract
We observed the 2017 July 17 stellar occultation of HD 168233 by the Kuiper Belt Object (486958) 2014 MU69, the close flyby target of the extended New Horizons mission. Rather than capture a solid body occultation by the KBO itself, our program aimed to constrain the opacity of rings, moons, or other debris in the nearby environment. We used the Hubble Space Telescope Fine Guidance Sensors (HST FGS) instrument in TRANS F583W mode to collect 40 Hz time resolution photometry of the stellar occultation star for two HST orbits during this observation. We present the results of reduction and calibration of the HST FGS photometry, and set upper limits on rings or other dust opacity within the Hill sphere of (486958) 2014 MU69 at distances ranging from ∼20000 km to ∼75000 km from the main body.
Rotation and Magnetism of Massive Stellar Cores
Authors: Kissin Yevgeni , Thompson Christopher 
Published: July 2018

Abstract
The internal rotation and magnetism of massive stars are considered in response to (i) the inward pumping of angular momentum through deep and slowly rotating convective layers, and (ii) the winding up of a helical magnetic field in radiative layers. Field winding can transport angular momentum effectively even when the toroidal field is limited by kinking. Magnetic helicity is pumped into a growing radiative layer from an adjacent convective envelope (or core). The receding convective envelope that forms during the early accretion phase of a massive star is the dominant source of helicity in its core, yielding a 1012 − 1013 G polar magnetic field in a collapsed neutron star (NS) remnant. Using MESA models of various masses, we find that the NS rotation varies significantly, from P
NS ∼ 0.1–1 s in a 13 M
⊙ model to P
NS ∼ 2 ms in a 25 M
⊙ model with an extended convective core. Stronger inward pumping of angular momentum is found in more massive stars, due to the growing thickness of the convective shells that form during the later stages of thermonuclear burning. On the other hand, stars that lose enough mass to form blue supergiants in isolation end up as very slow rotators. The tidal spin-up of a 40 M
⊙ star by a massive binary companion is found to dramatically increase the spin of the remnant black hole, allowing a rotationally supported torus to form during the collapse. The implications for post-collapse decay or amplification of the magnetic field are also considered.
The Metallicity Dependence of the H i Shielding Layers in Nearby Galaxies
Authors: Schruba Andreas , Bialy Shmuel , Sternberg Amiel 
Published: July 2018

Abstract
We investigate the metallicity dependence of H i surface densities in star-forming regions along many lines of sight within 70 nearby galaxies, probing kiloparsec to 50 pc scales. We employ H i, SFR, stellar mass, and metallicity (gradient) measurements from the literature, spanning a wide range (5 dex) in stellar and gas mass and (1.6 dex) in metallicity. We consider metallicities as observed, or rescaled to match the mass–metallicity relation determined for SDSS galaxies. At intermediate to high metallicities (0.3–2 times solar), we find that the H i surface densities saturate at sufficiently large total gas surface density. The maximal H i columns vary approximately inversely with metallicity, and show little variation with spatial resolution, galactocentric radius, or among galaxies. In the central parts of massive spiral galaxies, the H i gas is depressed by factors of ∼ 2. The observed behavior is naturally reproduced by metallicity dependent shielding theories for the H i-to-H2 transitions in star-forming galaxies. We show that the inverse scaling of the maximal H i columns with metallicity suggests that the area filling fraction of atomic-molecular complexes in galaxies is of the order of unity, and weakly dependent on metallicity.
