Exploring the origin of clumpy dust clouds around cool giants
Authors: Höfner Susanne , Freytag Bernd 
Published: February 2019

Context. Dust grains forming in the extended atmospheres of AGB stars are critical for the heavy mass loss of these cool luminous giants, as they provide radiative acceleration for the stellar winds. Characteristic mid-IR spectral features indicate that the grains consist mainly of silicates and corundum. The latter species seems to form in a narrow zone within about 2 stellar radii, preceding the condensation of silicate dust, which triggers the outflow. Recent high-angular-resolution observations show clumpy, variable dust clouds at these distances.
Aims. We explore possible causes for the formation of inhomogeneous dust layers, using 3D dynamical simulations.
Methods. We modeled the outer convective envelope and the dust-forming atmosphere of an M-type AGB star with the CO5BOLD radiation-hydrodynamics code. The simulations account for frequency-dependent gas opacities, and include a time-dependent description of grain growth and evaporation for corundum (Al2O3) and olivine-type silicates (Mg2SiO4).
Results. In the inner, gravitationally bound, and corundum-dominated layers of the circumstellar envelope, a patchy distribution of the dust emerges naturally, due to atmospheric shock waves that are generated by large-scale convective flows and pulsations. The formation of silicate dust at somewhat larger distances probably indicates the outer limit of the gravitationally bound layers. The current models do not describe wind acceleration, but the cloud formation mechanism should also work for stars with outflows. Timescales of atmospheric dynamics and grain growth are similar to observed values. In spherical averages of dust densities, more easily comparable to unresolved observations and 1D models, the variable 3D morphology manifests itself as cycle-to-cycle variations.
Conclusions. Grain growth in the wake of large-scale non-spherical shock waves, generated by convection and pulsations, is a likely mechanism for producing the observed clumpy dust clouds, and for explaining their physical and dynamical properties.
Evaluation and Management of Neck and Back Pain
Authors: Potter Samuel , Martel John 
Published: February 2019

AbstractNeck and back pain are common reasons for seeking evaluation and treatment in the emergency department. Within both systems there exist several time-sensitive diagnoses that the emergency provider should be familiar with in order to prevent significant morbidity and mortality. In this article we provide a general overview of these complaints by discussing problems in a systems-based fashion as well as discussing the initial evaluation, work-up, and treatment options for these diagnoses.
Movement Disorders Emergencies

Published: February 2019

AbstractMany acute and potentially life-threatening medical conditions have hyperkinetic or hypokinetic movement disorders as their hallmark. Here we review the clinical phenomenology, and diagnostic principles of neuroleptic malignant syndrome, malignant catatonia, serotonin syndrome, Parkinsonism hyperpyrexia, acute parkinsonism, acute chorea-ballism, drug-induced dystonia, and status dystonicus. In the absence of definitive lab tests and imaging, only a high index of clinical suspicion, awareness of at-risk populations, and variations in clinical presentation can help with diagnosis. We also discuss the principles of management and rationale behind treatment modalities in the light of more recent evidence.
Superior Vena Cava Cancerous Thrombus Due to Squamous Cell Tongue Cancer: Virchow's Triad at Its Worst Version
Authors: Papanikolaou John , Koukoubani Triantafyllia , Zakynthinos Epaminondas 
Published: February 2019

AbstractSuperior vena cava (SVC) cancerous thrombosis is extremely sparse, especially in the setting of extrathoracic tumours. Herein, we present the case of a patient with a squamous cell carcinoma of the tongue, who presented with SVC syndrome possibly secondary to symptomatic metastatic pericardial effusion. In this unique patient, the disastrous concurrence of all the elements of Virchow's triad within the confined anatomical space of SVC may have precipitated extensive vessel thrombosis with catastrophic consequences. To our knowledge, there has been no previous report about presence of SVC cancerous thrombosis in squamous cell tongue cancer. In this respect, our report may provide an unusual mechanism of tongue cancer expansion, which clinicians should be familiar with. In addition, it may highlight the clinical importance of SVC thrombosis on patients' clinical outcome, as well as the role of transoesophageal echocardiography in early detection of occult thrombi in the sub-set of patients with SVC syndrome.
Social Determinants of Gestational Weight Gain in an Obese, Low-Income Population
Authors: Ratan Bani Maheshwari , Garbarino Abigail Hook , Sellner Allison Archer , Miao Di , Hollier Lisa Marie 
Published: February 2019

Objective To examine how social support factors affect compliance with gestational weight gain (GWG) recommendations in an obese, low-income, predominantly minority population.
Study Design A retrospective cohort of 772 pregnant women with body mass index > 30 was reviewed. Univariate and multinomial logistic regression analyses were used to compare GWG with pregnancy planning, relationship status, participation in group prenatal care, nutritional education, and demographic factors. Subgroup analysis was performed to determine if differences existed in entry into prenatal care.
Results Planned nature of pregnancy, relationship status, nutritional education, and group prenatal care did not significantly affect GWG. Women with planned pregnancies and in group prenatal care had their first appointment during the first trimester at a higher rate than those with unplanned pregnancy and in traditional care, respectively. Regardless of timing of nutrition consult, GWG was not affected. Nulliparous patients and Class 1 obese patients were more likely to have excessive GWG.
Conclusion Social support factors in this study did not individually affect compliance with GWG recommendations in a low-income, obese pregnant population, although some factors were associated with earlier entry to prenatal care. Multimodal, longitudinal programs are likely necessary to achieve increased compliance with GWG recommendations in this population.

Published: February 2019

Background Left pulmonary artery (LPA) sling (PAS) is a vascular ring, which is frequently associated with long-segment tracheal stenosis (TS). Mortality rate in operated children is still high, especially in cases of severe tracheal hypoplasia and/or associated congenital heart defects (CHDs). We report our experience of treatment and follow-up in a pediatric cohort of patients affected by PAS with severe tracheobronchial involvement.
Methods From 2005 to 2017, we enrolled 11 children diagnosed with PAS and congenital TS requiring surgical intervention. Echocardiography, computed tomography, and bronchoscopy were performed in all patients. Associated CHD were present in 5 (45%) patients. Tracheal reconstruction techniques included slide tracheoplasty (7/11; 63%), slide tracheoplasty and costal cartilage graft (2/11; 18%), and Hazekamp technique (2/11; 18%).Nine patients underwent LPA direct reimplantation and concomitant tracheoplasty; concomitant surgical repair for CHD was performed in three children.
Results Over a mean follow-up of 30 months (range: 3–75 months), a late mortality of 18% was registered; no early death occurred. Good flow through LPA could be documented in all patients. Ten children required operative bronchoscopies (mean: 16/patients) aimed at stent positioning/removal, treatment of granulomas, and tracheobronchial dilatation.
Conclusions Severe tracheobronchial stenosis and associated CHD were the main determinants for hospitalization time, intensive assistance, and repeated endoscopic procedures.Patients affected by PAS/TS complex require a careful management at high-specialized centers providing multidisciplinary team.Respiratory endoscopy may play a central role both in preoperatory assessment and in postoperative management of patients showing severe tracheobronchial involvement.
Management of Patients Taking Oral Anticoagulants Who Need Urgent Surgery for Hip Fracture
Authors: Ostuni Angelo , Tiscia Giovanni , Marongiu Francesco , Barcellona Doris , Grandone Elvira 
Published: February 2019

AbstractThe number of hip fractures in anticoagulated patients is predicted to increase, due to people living longer. However, evidence regarding urgent perioperative management of elderly patients with hip fracture who take oral anticoagulants (vitamin K antagonists or direct oral anticoagulants) is scarce. In this article, the authors present a narrative review of the evidence to date supporting the urgent management of hip fracture in anticoagulated elderly patients. They discuss the complexity of managing the high risk of procedure-related bleeding and, at the same time, the high risk of thromboembolism. The role of a bridging procedure and the best strategy of anticoagulation reversal are also reviewed. Further studies are required to improve the evidence in urgent surgery, especially in frail elderly patients.

Published: February 2019

ABSTRACTHere, we investigated the effects and molecular mechanisms of metabotropic glutamate receptor 6 (mGluR6) on rat embryonic neural stem cells (NSCs). Overexpression of mGluR6 significantly promoted the proliferation of NSCs and increased the diameter of neutrospheres after treatment for 24 h, 48 h and 72 h. Overexpression of mGluR6 promoted G1 to S phase transition, with significantly decreased cell ratio in G1/G0 phase but significantly increased cell ratio in S phase. Additionally, mGluR6 overexpression for 48 h decreased the early and late apoptosis significantly. Moreover, overexpression of mGluR6 significantly increased the expression of p-ERK1/2, Cyclin D1 and CDK2, while the expression of p-p38 was significantly decreased. On the contrary, these effects of mGluR6 overexpression were reversed by mGluR6 knockdown. In conclusion, mGluR6 promotes the proliferation of NSCs by activation of ERK1/2-Cyclin D1/CDK2 signaling pathway and inhibits the apoptosis of NSCs by blockage of the p38 MAPK signaling pathway.
Weight loss effect of sweet orange essential oil microcapsules on obese SD rats induced by high-fat diet

ABSTRACT
Obesity is one of the most common and major health concerns worldwide. Weight management through dietary supplements with natural plant extracts has become the focus of current research. Sweet orange essential oil (SOEO) is a natural plant extract, with many bioactivities. In order to evaluate the weight loss effect of SOEO microcapsules and investigate the underlying mechanism, we fed high-fat diet-induced obese SD rats with SOEO microcapsules for 15 days and found that SOEO microcapsules reduced body weight gain by 41.4%, decreased total cholesterol level, alleviated liver and adipose tissue pathological alteration. The results of fluorescence quantitative PCR revealed that decreasing the expression of peroxisome proliferators-activated receptor-γ, upregulating of uncoupling protein 2, hormone sensitive lipase and carnitine palmitoyltransferase I, inhibiting the expression of acetyl-CoA carboxylase appear to be the mechanism of SOEO microcapsules to lose weight. This study suggests that SOEO microcapsule is a potential dietary supplement for weight loss.

Abstract
The well-known cluster of galaxies ZwCl0024+1652 at z ∼ 0.4 lacks an in-depth morphological classification of its central region. While previous studies provide a visual classification of a patched area, we used the public code called galaxy Support Vector Machine (galsvm) and HST/ACS data as well as the WFP2 master catalogue to automatically classify all cluster members up to 1 Mpc. galsvm analyses galaxy morphologies through support vector machine (SVM). From the 231 cluster galaxies, we classified 97 as early types (ETs) and 83 as late types (LTs). The remaining 51 stayed unclassified (or undecided). By cross-matching our results with the existing visual classification, we found an agreement of 81 per cent. In addition to previous Zwcl0024 morphological classifications, 121 of our galaxies were classified for the first time in this work. In addition, we tested the location of classified galaxies on the standard morphological diagrams, colour–colour and colour–magnitude diagrams. Out of all cluster members, ∼20 per cent are emission-line galaxies, taking into account previous GLACE results. We have verified that the ET fraction is slightly higher near the cluster core and decreases with the clustercentric distance, while the opposite trend has been observed for LT galaxies. We found a higher fraction of ETs (54  per cent) than LTs (46  per cent) throughout the analysed central region, as expected. In addition, we analysed the correlation between the five morphological parameters (Abraham concentration, Bershady–Concelice concentration, asymmetry, Gini, and M20 moment of light) and the clustercentric distance, without finding a clear trend. Finally, as a result of our work, the morphological catalogue of 231 galaxies containing all the measured parameters and the final classification is available in the electronic form of this paper.
Queering Scholarship?
Authors: Thiel Markus 
Published: February 2019

Abstract
With the emergence of global LGBT issues as focal points for domestic and international politics, a theoretical examination of their impact on scholarship becomes necessary in order to broaden international relations (IR) and political science and re-evaluate some of the central tenets and concepts in those disciplines. LGBT politics are often theorized in LGBT studies, which more conventionally trace the impact of such politics, but also increasingly in queer studies, which advance critical, deconstructive perspectives stemming from sexuality and gender. The author asks why LGBT and queer studies have not made earlier inroads into IR and political science, accounts for the theoretical as well as methodological challenges that LGBT politics pose for those disciplines, and highlights some of the open questions that remain to be answered in the future.
Axon Trajectories in the Auditory Brainstem
Authors: Cant Nell Beatty 
Published: February 2019

Abstract
This chapter summarizes what is known about the organization of the axons that make up the white matter of the auditory brainstem. The sources of the axons in each of the major fiber bundles (the dorsal and intermediate acoustic striae, the ventral acoustic stria or trapezoid body, and the lateral lemniscus) are reviewed, and, where information is available, the organization of specific groups of axons within the fiber bundles is described. The chapter collects the extensive but scattered information about axon trajectories into one place, both to provide a summary of what is known and also to indicate important gaps in our knowledge. The emphasis is almost entirely on the routes followed by groups of axons over the relatively long distances between structures and on the organization of specific types of axons within the fiber bundles; information about the termination patterns of the axons can be obtained from the references cited and throughout the chapter. Because knowledge about axon trajectories has considerable practical value (as, for example, in designing and interpreting both anatomical and physiological studies), the most useful information is species specific. Fortunately, at least at our current level of understanding, the components and relative positions of the major fiber bundles are remarkably similar across species (undoubtedly reflecting a common mammalian developmental plan).
The Colonizing Other
Authors: Anderson Emily 
Published: February 2019

Abstract
This chapter provides an overview of the key historical factors that led Japanese Christians to develop their beliefs and practices in the context of early twentieth-century Japan. It places the emergence of Protestant Christianity within the larger context of Japan’s uncomfortable return to diplomatic and economic ties with western powers after over two centuries of self-imposed isolation. It particularly focuses on Christian engagement with Japan’s emergence as a colonial empire. The chapter also discusses whether or not the Bible supported colonial expansion or political dissent. In addition to offering a survey of relevant existing scholarship, it also introduces some of the key figures who engaged in these debates.
Jewish Negotiations of Hellenistic Power
Authors: Carter Warren 
Published: February 2019

Abstract
Much scholarship has addressed the question of how Jewish writings negotiated Hellenistic imperial and cultural power. These negotiations began in the time of Alexander (d. 323), continuing through the Ptolemaic and Seleucid empires until the assertion of Roman hegemony over Judaea/Israel in 63 bce. This chapter briefly reviews some recent discussions, noting significant interactions as well as neglected complexities. It then adopts a postcolonial optic to foreground inequalities in the assertions of power, along with the often invisible colonized and their agencies and voices. The chapter also discusses situations marked by ambivalence, mimicry, consensual-conflictive hybridity, native fractures, and the mutual dependence of colonizer and colonized.
Postcolonial Liberation
Authors: West Gerald O. 
Published: February 2019

Abstract
Liberation biblical interpretation and postcolonial biblical interpretation have a long history of mutual constitution. This essay analyzes a particular context in which these discourses and their praxis have forged a third conversation partner: decolonial biblical interpretation. African and specifically South African biblical hermeneutics are the focus of reflections in this essay. The South African postcolony is a “special type” of postcolony, as the South African Communist Party argued in the 1960s. The essay charts the characteristics of the South African postcolony and locates decolonial biblical interpretation within the intersections of these features. Race, culture, land, economics, and the Bible are forged in new ways by contemporary social movements, such as #FeesMustFall. South African biblical studies continues to draw deeply on the legacy of South African black theology, thus reimagining African biblical studies as decolonial African biblical studies—a hybrid of African liberation and African postcolonial biblical interpretation.
Uses of high-flow nasal cannula on the community paediatric ward and risk factors for deterioration
Authors: De Santis Diana , Sheriff Falana , Bester Deborah , Shahab Rabia , Hutzal Carolyn 
Published: February 2019

Abstract

Background
High-flow nasal cannula (HFNC) is a form of noninvasive respiratory support used for paediatric acute respiratory illnesses. Past HFNC research has focused on its use in bronchiolitis and in intensive care units, but little is reported on its use in the community hospital setting. We aimed to investigate the paediatric population using HFNC, any adverse events, and risk factors for deterioration.

Methods
A retrospective chart review was performed on patients admitted to a community paediatric ward. Inclusion criteria were patients between 1 day and 17 years of age, admitted between September 2013 and April 2016, and treated with HFNC for at least 4 hours.

Results
A total of 85 children met inclusion criteria. The average age of patients in our study was 3.41 years with 39% of patients &gt;2 years of age. 46% of patients had an admitting diagnosis of bronchiolitis, 33% pneumonia, and 16% with asthma. Transfer rate to tertiary care centre paediatric intensive care unit was 18%. Patients transferred required greater FIO2 (odds ratio [OR] 1.04, P=0.018, confidence interval [CI] 1.007 to 1.082), and were 3.2 times more likely to be positive for respiratory syncytial virus (RSV) (P=0.081, CI 0.868–11.739). There were no adverse events attributed to HFNC in the population.

Conclusion
HFNC is being utilized in the community hospital setting for children of varied age and types of respiratory illnesses. Children requiring higher FIO2 are at risk of respiratory deterioration which may identify them earlier for transfer to tertiary care. Further research into the safety and efficacy of HFNC for different paediatric illnesses in the community is needed.
Inquiline social parasites as tools to unlock the secrets of insect sociality
Authors: Cini Alessandro , Sumner Seirian , Cervo Rita 
Published: February 2019

Insect societies play a crucial role in the functioning of most ecosystems and have fascinated both scientists and the lay public for centuries. Despite the long history of study, we are still far from understanding how insect societies have evolved and how social cohesion in their colonies is maintained. Here we suggest inquiline social parasites of insect societies as an under-exploited experimental tool for understanding sociality. We draw on examples from obligate inquiline (permanent) social parasites in wasps, ants and bees to illustrate how these parasites may allow us to better understand societies and learn more about the evolution and functioning of insect societies. We highlight three main features of these social parasite–host systems—namely, close phylogenetic relationships, strong selective pressures arising from coevolution and multiple independent origins—that make inquiline social parasites particularly suited for this aim; we propose a conceptual comparative framework that considers trait losses, gains and modifications in social parasite–host systems. We give examples of how this framework can reveal the more elusive secrets of sociality by focusing on two cornerstones of sociality: communication and reproductive division of labour. Together with social parasites in other taxonomic groups, such as cuckoos in birds, social parasitism has a great potential to reveal the mechanisms and evolution of complex social groups.This article is part of the theme issue ‘The coevolutionary biology of brood parasitism: from mechanism to pattern’.
