Connecting Giant Planet Atmosphere and Interior Modeling: Constraints on Atmospheric Metal Enrichment
Authors: Thorngren Daniel , Fortney Jonathan J. 
Published: April 2019

Abstract
Atmospheric characterization through spectroscopic analysis, an essential tool of modern exoplanet science, can benefit significantly from the context provided by the interior structure models. In particular, the planet’s bulk metallicity, Z

p
, places an upper limit on the potential atmospheric metallicity. Here we construct interior structure models to derive Z

p
and atmospheric metallicity upper limits for 403 known transiting giant exoplanets. These limits are low enough that they can usefully inform atmosphere models. Additionally, we argue that comparing Z

p
to the observed atmospheric metallicity gives a useful measure of how well mixed metals are within the planet. This represents a new avenue for learning about planetary interiors. To aid in the future characterization of new planet discoveries we derive analytic prior predictions of atmosphere metallicity as a function of planet mass, and evaluate the effectiveness of our approach on Jupiter and Saturn. We include log-linear fits for approximating the metallicities of planets not in our catalog.

Abstract
We report high spatial resolution (∼0.″076, 410 pc) Atacama Large Millimeter/submillimeter Array imaging of the dust continuum and the ionized carbon line [C ii] in a luminous quasar host galaxy at z = 6.6, 800 million years after the big bang. Based on previous studies, this galaxy hosts a ∼1 × 109

black hole and has a star formation rate of ∼1500

yr−1. The unprecedented high resolution of the observations reveals a complex morphology of gas within 3 kpc of the accreting central black hole. The gas has a high velocity dispersion with little ordered motion along the line of sight, as would be expected from gas accretion that has yet to settle in a disk. In addition, we find the presence of [C ii] cavities in the gas distribution (with diameters of ∼0.5 kpc), offset from the central black hole. This unique distribution and kinematics cannot be explained by a simple model. Plausible scenarios are that the gas is located in a truncated or warped disk, or the holes are created by interactions with nearby galaxies or due to energy injection into the gas. In the latter case, the energy required to form the cavities must originate from the central active galactic nucleus, as the required energy far exceeds the energy output expected from supernovae. This energy input into the gas, however, does not inhibit the high rate of star formation. Both star formation and black hole activity could have been triggered by interactions with satellite galaxies; our data reveal three additional companions detected in [C ii] emission around the quasar.
The impact of workplace bullying on flourishing: The moderating role of emotional intelligence
Authors: Nel Elizabeth C. 
Published: April 2019

Orientation: Workplace bullying has detrimental effects on employee well-being. Emotional intelligence may moderate the relationship between workplace bullying and flourishing.Research purpose: The purpose of this study was to examine the nature of the relationship between workplace bullying and flourishing and to investigate the moderating role of emotional intelligence in the workplace bullying–flourishing relationship.Motivation for the study: There is a paucity of studies exploring the moderating role of personal resources such as emotional intelligence in the relationship between workplace bullying and flourishing.Research approach/design and method: The study used a cross-sectional design, quantitative approach and a convenience sampling method. Employees from a higher education institution (N = 1102) participated in this research. Descriptive, correlation and moderation analysis was used to analyse the data.Main findings: The results showed that there was a significant negative relationship between workplace bullying and flourishing. Emotional intelligence significantly moderated the relationship between workplace bullying and flourishing.Practical/managerial implications: Organisations should develop and/or strengthen the level of emotional intelligence in employees in order to reduce the negative effect of workplace bullying on well-being.Contribution/value-add: The findings of this research contribute to the limited body of research investigating personal resources such as emotional intelligence as a moderator in the bullying-well-being relationship.
A rare case of neonatal mastauxe: Case report
Authors: Suthar Bhumika , Aggarwal Kanishka 
Published: April 2019

AbstractNeonatal breast enlargements have varying number of presentations on imaging and these have been underreported in the literature. Our case report profiles a 2-week-old female who presented with a history of bilateral breast enlargement with redness and clear, non-bloody, milk-like discharge, who was clinically diagnosed and managed for neonatal mastitis, which was actually a neonatal breast enlargement only. Awareness on neonatal breast enlargement that can be just physiological without any associated mastitis or inflammatory/infective changes can prevent unnecessary hospitalization and treatment with parenteral antibiotics.

Published: April 2019

Abstract
Background of the Article: Hepatocellular carcinoma (HCC) is one of the most common human malignancies worldwide. Radiofrequency ablation (RFA) is considered curative option in selected patients; efficacy is severely limited by lesion size and lesions bordering a large vessel. On the other hand, transarterial chemoembolization (TACE) is not limited by lesion size and arterial occlusion of the tumor feeding vessels leads to increase the volume of the ablative zone. Combination treatments using both intraarterial liver-directed therapy and percutaneous ablation seek to overcome the disadvantages of the individual treatments alone, theoretically improving response to therapy and survival. Material and Methods: This is a single-center retrospectively study in which patients who received TACE plus RFA for HCC were evaluated for technical success, local tumor progression rates, distant intra and extrahepatic recurrences and survival. Results: The study included 22 patients, 21 patients had a solitary HCC of size 3–7 cm and one patient had three target lesions. Technical success achieved after first session of combination treatment was 100% (24/24). At 1 and 3 months follow-up 100% patients (24 target lesions) had complete response and at 6 months; 21 (87.5%) had complete response, one (4.2%) had local tumor progression and two patients (8.3%) developed progressive disease. No major difference in complication was noted. The event-free survival as shown by Kaplan–Meier graph analysis at 6 and 12 months were 90.7% and 66.4% with mean time to event-free survival was 11.1 months. Conclusion: The combined use of TACE and RFA is a safe and effective option in the treatment of patients with single large or multinodular HCC when surgical resection is not feasible and this approach provides better results than RFA or TACE alone.
Ultrasonography and X-Ray guided drain placement to evacuate a pneumopericardium/pneumomediastinum in a 1-day-old infant
Authors: Bhat Ambarish P , Pimpalwar Ashwin , Dyke II Peter C 
Published: April 2019

AbstractUltrasonographic (US) guided procedures have wide range of application in the abdomen and pelvis, however their role is somewhat limited in the chest due to complete reflection of the ultrasound beam by the air in the lungs, preventing the direct imaging of the tissues deep to the air-sound interface. Most of the chest procedures, other than the exception of thoracentesis, rely on the use of CT (computed tomography) scan. The disadvantages of using CT scan is the cost, lack of portability, and most importantly the radiation involved, particularly in case of infants and children, whose tissues are more radiosensitive than the adults. Identification of air by Ultrasonography can help direct needles and wires, to accomplish procedures which may otherwise need CT. A 1-day-old infant with respiratory distress syndrome (RDS) on a ventilator, developed an expanding symptomatic pneumopericardium/pneumomediastinum. The patient was too unstable to leave the neonatal intensive care unit (NICU), so a pericardial/mediastinal drain was placed under ultrasonographic and radiographic guidance. This case, highlights a method for bedside treatment of pneumopericardium/pneumomediastinum in an unstable neonate. This procedure may be equally effective in older children and adults.

Published: April 2019

AbstractA 69-year-old male patient, with bilateral hypoacusia and tinnitus, had a diagnosis of left vestibular schwannoma with synchronous meningioma on the left frontal lobe. After partial surgical resection of the acoustic schwannoma, this was followed by stereotactic radiosurgery on the residual lesion. The patient had a metachronous prostate cancer treated with conformal radiotherapy associated to 6 months of hormone therapy with luteinizing hormone/releasing hormone analog. During follow-up, prostate-specific antigen value increased to 0.27 ng/mL and the patient underwent 18F-methylcholine positron emission tomography/computed tomography (18F-choline PET/CT). The whole-body scan demonstrated a focus of increased uptake at level of the left cerebellopontine angle and at the left frontal lobe, corresponding to the known vestibular schwannoma and meningioma. A subsequent brain contrast-enhanced magnetic resonance imaging (MRI) showed an increased dimension of the left cerebellopontine neuroma and dimensional stability of the left frontal meningioma compared with previous MRI of 6 months earlier. To the best of our knowledge, we describe the first case of a 18F-choline PET/CT demonstrating a relapse of a vestibular schwannoma after stereotactic radiotherapy.
Semiquantitative assessment of osteoblastic, osteolytic, and mixed lytic-sclerotic bone lesions on fluorodeoxyglucose positron emission tomography/computed tomography and bone scintigraphy
Authors: Gurkan Guray , Sarikaya Ismet , Sarikaya Ali 
Published: April 2019

AbstractBone scintigraphy is widely used to detect bone metastases, particularly osteoblastic ones, and F-18 fluorodeoxyglucose (FDG) positron emission tomography (PET) scan is useful in detecting lytic bone metastases. In routine studies, images are assessed visually. In this retrospective study, we aimed to assess the osteoblastic, osteolytic, and mixed lytic-sclerotic bone lesions semiquantitatively by measuring maximum standardized uptake value (SUVmax) on FDG PET/computed tomography (CT), maximum lesion to normal bone count ratio (ROImax) on bone scintigraphy, and Hounsfield unit (HU) on CT. Bone scintigraphy and FDG PET/CT images of 33 patients with various solid tumors were evaluated. Osteoblastic, osteolytic, and mixed lesions were identified on CT and SUVmax, ROImax, and HU values of these lesions were measured. Statistical analysis was performed to determine if there is a difference in SUVmax, ROImax, and HU values of osteoblastic, osteolytic, and mixed lesions and any correlation between these values. Patients had various solid tumors, mainly lung, breast, and prostate cancers. There were 145 bone lesions (22.8% osteoblastic, 53.1% osteolytic, and 24.1% mixed) on CT. Osteoblastic lesions had a significantly higher value of CT HU as compared to osteolytic and mixed lesions (P < 0.01). There was no significant difference in mean ROImaxand mean SUVmaxvalues of osteolytic and osteoblastic bone lesions. There was no correlation between SUVmaxand ROImax, SUVmaxand HU, and ROImaxand HU values in osteolytic, osteoblastic, and mixed lesions (P > 0.05). Not finding a significant difference in SUVmaxand ROImaxvalues of osteoblastic, osteolytic, and mixed lesions and also lack of correlation between SUVmax, ROImax, and HU values could be due to treatment status of the bone lesions, size of the lesion, nonmetastatic lesions, erroneous measurement of SUVmaxand ROImax, or varying metabolism in bone metastases originating from various malignancies.

AbstractThe aim of this observational cross-sectional study with retrospective review of the data is to evaluate the efficacy of using technetium-99m-octreotide (Tc-99m-OCT) in imaging neuroendocrine tumors (NETs) in our tertiary care hospital. A total of 58 patients had Tc-99m-OCT were identified in our database, from January 2013 to December 2016. Forty-one patients (age range of 15–75 years) meet our inclusion criteria, namely histopathology proven NETs, Tc-99m-OCT scan, computed tomography (CT), or magnetic resonance imaging (MRI) done in our institute for correlation. Twenty-three patients had true positive Tc-99m-OCT scan. In addition to the primary tumors, the octreotide scan revealed metastasis in the lung, liver, and retroperitoneal lymph nodes. The smallest lesion detected on octreotide scan was a 4-mm pulmonary nodule that was missed on lung window CT scan. The Tc-99m-OCT had 17 true negative, one false negative, and no false positive. The CT and MRI scans had 18 true positive, 17 true negative, 5 false negative, and one false positive. The overall sensitivity, specificity, accuracy, positive, and negative predictive values of Tc-99m-OCT scan were 96%, 100%, 97%, 100%, and 94%, respectively. Whereas those of CT and MRI were 78%, 94%, 85%, 94%, and 77%, respectively. Our diagnostic accuracy of Tc-99m-OCT is high. We recommend that, in addition to the conventional radiological investigations, Tc-99m-OCT scan, or other somatostatin receptor imaging (SSR) is a mandate for better and accurate staging of patients with NETs.
A new role for fluorine-18-fluorodeoxyglucose positron-emission tomography/computed tomography in Erdheim-Chester disease
Authors: Van Keerberghen Ciska-Anne , Harrouk Antoine , Leone Luca 
Published: April 2019

AbstractErdheim-Chester disease (ECD) is a rare form of non-Langerhans cell histiocytosis, with multisystem manifestation such as bone pain, being the most common presenting symptom, cardiovascular or central nervous system involvement, interstitial lung disease, skin and orbital lesions, adrenal enlargement, retroperitoneal fibrosis and renal impairment as well fever, and weight loss. The disease is challenging to diagnose due to its rarity and mimicry of other infiltrative processes. Technetium-99 m bone scintigraphy showing pathological bone activity in the long bones is highly suggestive of ECD. However, not all patients have bone complaints. Till now, fluorine-18-fluorodeoxyglucose positron-emission tomography/computed tomography (18F-FDG PET/CT) was especially used after histological diagnosis to determine disease activity and extent, as well as the evaluation of treatment response. With this case, we suggest an additional role for 18F-FDG PET/CT earlier on in the diagnosis workup as follows: detecting a possible biopsy site to establish the diagnosis of ECD especially in a clinical context without bone pain.

Abstract. Tritium and helium isotope data provide key information on ocean
circulation, ventilation, and mixing, as well as the rates of biogeochemical
processes and deep-ocean hydrothermal processes. We present here global
oceanic datasets of tritium and helium isotope measurements made by numerous
researchers and laboratories over a period exceeding 60 years. The dataset's
DOI is https://doi.org/10.25921/c1sn-9631, and the data are available at
https://www.nodc.noaa.gov/ocads/data/0176626.xml (last access: 15 March
2019) or alternately
http://odv.awi.de/data/ocean/jenkins-tritium-helium-data-compilation/
(last access: 13 March 2019) and includes approximately 60 000 valid tritium
measurements, 63 000 valid helium isotope determinations, 57 000 dissolved
helium concentrations, and 34 000 dissolved neon concentrations. Some
quality control has been applied in that questionable data have been flagged
and clearly compromised data excluded entirely. Appropriate metadata have
been included, including geographic location, date, and sample depth. When
available, we include water temperature, salinity, and dissolved oxygen. Data
quality flags and data originator information (including methodology) are
also included. This paper provides an introduction to the dataset along with
some discussion of its broader qualities and graphics.

Esta investigación aborda a partir de la Teoría de la Generalizabilidad (TG) la optimización de recursos en la gestión deportiva. Se utilizó una estructura de diseño compuesta por las facetas usuarios (U), actividades (A), escalas (E) e ítems (I), siguiendo un diseño no ortogonal, parcialmente anidado y multifaceta dentro del Modelo General Lineal (GLM). Los 537 participantes (32.11 ± 11.11 años) cumplimentaron el Cuestionario de Evaluación de la Calidad Percibida en Servicios Deportivos obteniendo resultados excelentes de fiabilidad (ξρ²(δ) > 0.98) y generalizabilidad (ξρ²(Δ) > 0.98). La optimización mostró que con una reducción del número de participantes a la mitad y con un menor número de actividades evaluadas, obtenemos un alto grado de generalización al mismo tiempo que se reduce el número total de observaciones de cara a futuros registros, lo que facilitará la evaluación del servicio deportivo de manera más eficiente.
This paper addresses from the use of the Generalizability Theory (TG) the optimization of resources in sports management. We used a design structure composed of the facets users (U), activities (A), scales (E) and items (I), following not orthogonal design, partially nested and multifaceted, within the General Linear Model. 537 participants (32.11 ± 11.11 years) completed the Questionnaire of Evaluation of the Perceived Quality in Sports Services obtaining excellent results both indexes of reliability (ξρ²(δ) > 0.98) and generalizability (ξρ²(Δ) > 0.98). The optimization showed that half of participants and fewer activities, we obtain a high degree of generalization and at the same time, reduced the total number of observations, being important for future studies which will facilitate the evaluation of sport service more efficiently.
