The Cannibal’s Gaze: A Reflection on the Ethics of Care Starting from Salvador Dalí’s Oeuvre
Authors: TUROLDO FABRIZIO 
Published: March 2020

AbstractStarting from two paintings by Salvador Dalì (The Enigma of William Tell and Autumnal Cannibalism), the article explores Sigmund Freud and Carl Gustav Jung’s idea of erotic cannibalism. The fear of being eaten is an archetype of the collective unconscious, as fairy tales clearly reveal. Following Jacques Derrida’s reflections, the author suggests that the fear of being eaten is not limited to anthropophagic cultures, because there is a sort of symbolic cannibalism which has to do with the capacity for annihilation. The petrifying gaze of Medusa, described by Jean Paul Sartre, is a good example of this symbolic cannibalism. On the opposite side of the spectrum, compared to the petrifying gaze, we find the recognizing look of a mother toward her child. For the child, the mother embodies the good subject, which is reassuring and nonthreatening (the fairy who stands in contrast to the devouring ogre in fairy tales). Sara Ruddick explicitly refers to this motherhood model in her book Maternal Thinking, where she lays out the methodology for the ethics of care. The maternal, or recognizing gaze, as the opposite of Medusa’s gaze portrayed by Sartre, is well described in a compelling text by the Italian novelist Luigi Pirandello. At the same time, it plays an important role in Georg Wilhelm Friedrich Hegel’s The Phenomenology of the Spirit. Finally, the article returns to Salvador Dalì, showing how in his life, the artist experienced the Other’s gaze in both forms: the objectifying one, represented by the artist’s father (portrayed in The Enigma of William Tell), and the recognizing one, embodied by his partner Gala (portrayed in Autumnal Cannibalism).
The emergence of multiple populations in radiation hydrodynamics simulations of cluster formation
Authors: Sills Alison 
Published: March 2020

AbstractWe present a new approach to understanding star-to-star helium abundance variations within globular clusters. We begin with detailed radiation hydrodynamics simulations of cluster formation within giant molecular clouds, and investigate the conditions under which multiple populations could be created. Chemical enrichment occurs dynamically as the cluster is assembled. We test two extreme mechanisms for injection of enriched gas within the clusters, and find that realistic multiple populations can be formed in both mechanisms. The stochastic cluster formation histories are dictated by the inherent randomness of the timing and location of the formation of small clusters, which rapidly merge to build up the larger cluster, in combination with continual accretion of gas from the cloud. These cluster formation histories naturally produce a diversity of abundance patterns across the massive cluster population. We conclude that multiple populations are a natural outcome of the typical mode of star cluster formation.
Internal kinematics of multiple stellar populations in globular clusters
Authors: Libralato Mattia 
Published: March 2020

AbstractSpectroscopy and photometry have revealed existence, complexity and properties of the multiple stellar populations (mPOPs) hosted in Galactic globular clusters. However, the conundrum of the formation and evolution of mPOPs is far from being completely exploited: the available pieces of information seem not enough to shed light on these topics. Astrometry, and in particular high-precision proper motions, can provide us the sought-after answers about how mPOPs formed and have evolved in these ancient stellar systems. In the following, I present a brief overview of the observational results on the internal kinematics of the mPOPs in some GCs thanks to Hubble Space Telescope high-precision proper motions.

Published: March 2020

AbstractWe present preliminary results of the wide-field photometric study of the isolated elliptical galaxy NGC 1172, and its globular cluster system. Our data was obtained with the GMOS camera mounted on the Gemini South telescope, in the g′, r′, i′ and z′ bands. The aim of this work is to further our understanding of the evolution of NGC 1172, and to look for possible explanations for its unusual high specific frequency.
Star Clusters in the Galactic tidal field, from birth to dissolution
Authors: Shukirgaliyev Bekdaulet , Parmentier Genevieve , Berczik Peter , Just Andreas 
Published: March 2020

AbstractWe study the evolution of star clusters in the Galactic tidal field starting from their birth in molecular clumps. Our model clusters form according to the local-density-driven cluster formation model in which the stellar density profile is steeper than that of gas. As a result, clusters resist the gas expulsion better than predicted by earlier models.We vary the impact of the Galactic tidal field λ, considering different Galactocentric distances (3-18 kpc), as well as different cluster sizes. Our model clusters survive the gas expulsion independent of λ.We investigated the relation between the cluster mass at the onset of secular evolution and their dissolution time. The model clusters formed with a high star-formation efficiency (SFE) follow a tight mass-dependent dissolution relation, in agreement with previous theoretical studies. However, the low-SFE models present a shallower mass-dependent relation than high-SFE clusters, and most dissolve before reaching 1 Gyr (cluster teenage mortality).
Breaking the dichotomy between typical and anomalous globular clusters: the case of NGC 3201
Authors: Dias Bruno , Araya Ignacio , Nogueira-Cavalcante João Paulo , Saker Leila , Shokry Ahmed 
Published: March 2020

AbstractWe recently discovered that NGC 3201 has characteristics that set it outside the current twofold classification scheme for Galactic globular clusters (GCs). Most GCs are mono-metallic and show light-element abundance variations (e.g., Na-O and C-N anti-correlations); but a minority of clusters also present variations in Fe correlating with s-process element and C+N+O abundances, and they possess multiple C-N sequences. These anomalous GCs also have a broad sub-giant branch (SGB) and follow the same mass-size relation as dwarf galaxies possibly evolving into GCs. We now revealed that NGC 3201 belongs to neither group. It has multiple C-N sequences, but no broad SGB, no strong evidence of a Fe-spread, and it does not follow the mass-size relation.
Globular Cluster — Bulge connection: Population synthesis models with multiple populations

Published: March 2020

AbstractRecent analyses of Lee et al. (2018, 2019) have confirmed that Galactic bulge consists of stellar populations originated from Milky Way globular clusters (MWGCs). Motivated by this, here we present the evolutionary population synthesis (EPS) for the Galactic bulge and early-type galaxies (ETGs) with the realistic treatment of individual variations in light elements observed in the MWGCs. We have utilized our model with GC-origin populations to explain the CN spread observed in ETGs, and the results show remarkable matches with the observations. We further employ our model to estimate the age of ETGs, which are considered as good analogs for the MW bulge. We find that, without the effect of our new treatments, EPS models will almost always underestimate the true age of ETGs. Our analysis indicates that the EPS with GC-origin populations is an essential constraint in determining the ETG formation epoch and is closely related to understanding the evolution of the Universe.
The eye of Gaia on globular cluster kinematics: Internal rotation
Authors: Sollima A. , Baumgardt H. , Hilker M. 
Published: March 2020

AbstractI present the results of a survey of the kinematics of a large sample of Galactic globular clusters performed thanks to the synergy between the 2nd Gaia data release and the most extensive collection of radial velocities. This unprecedented dataset of 3D velocities of thousand of stars in 62 globular clusters has been used to investigate the rotation patterns of these stellar systems providing insight into the impact of two-body relaxation and tides on the formation and evolution of their rotation.
The range of UV upturn strengths in early-type galaxies can be caused by dissolved metal-rich Globular Clusters
Authors: Goudfrooij Paul 
Published: March 2020

AbstractI summarize the scenario by Goudfrooij (2018) in which the bulk of the ultraviolet (UV) upturn of giant early-type galaxies (ETGs) is due to helium-rich stellar populations that formed in massive metal-rich globular clusters (GCs) and subsequently dissolved in the strong tidal field in the central regions of the massive host galaxy. These massive GCs are assumed to show UV upturns similar to those observed recently in M87, the central galaxy in the Virgo cluster of galaxies. Data taken from the literature reveals a strong correlation between the strength of the UV upturn and the specific frequency of metal-rich GCs in ETGs. Adopting a Schechter function parametrization of GC mass functions, simulations of long-term dynamical evolution of GC systems show that this correlation can be explained by variations in the characteristic truncation mass Mc such that Mc increases with ETG luminosity in a way that is consistent with observed GC luminosity functions in ETGs. These findings suggest that the nature of the UV upturn in ETGs and the variation of its strength among ETGs are causally related to that of helium-rich populations in massive GCs, rather than intrinsic properties of field stars in ETGs.
The Role of Climate Sensitivity in Upper‐Tail Sea Level Rise Projections

Published: March 2020

AbstractThe current uncertainty surrounding the Earth's equilibrium climate sensitivity is an important driver for climate hazard projections. While the implications for projected global temperature changes have been extensively studied, the impacts on sea level projections have been relatively unexplored. Here we analyze the relationship between the climate sensitivity and sea level projections, with a particular focus on the high‐impact upper tail. We utilize a Bayesian calibration of key climate and sea level parameters using historical observations and the reduced‐complexity Earth system model, Hector‐BRICK. This methodology allows us to focus on plausible realizations of the climate system in a probabilistic framework. We analyze the effects of high‐end climate sensitivity (above 5 K) on projections and spatial patterns of sea level change. The sea level projections hinge critically on the upper tail of the climate sensitivity, especially for the highly decision‐relevant upper tail. Results have important implications for timing of threshold exceedances and regional variability.
Is There a Nascent Plate Boundary in the Northern Indian Ocean?
Authors: Coudurier‐Curveur A. , Karakaş Ç. , Singh S. , Tapponnier P. , Carton H. , Hananto N. 
Published: March 2020

AbstractThe northern Indian Ocean has been widely recognized as an area of broadly distributed deformation within the composite India‐Australia‐Capricorn plate, hosting several diffuse boundary zones and a diffuse triple junction. The occurrence, along reactivated fracture zones, of the exceptionally large (Mw = 8.6 and Mw = 8.2) 2012 Wharton Basin strike‐slip earthquakes, however, questions whether this composite plate is breaking apart along a discrete boundary. Using recent bathymetric and seismic data, we analyze the most prominent fracture zone (F6a), whose structural trace is particularly well expressed. We identify 60 kilometric‐scale pull‐apart basins with geometric properties (length/width ratios) similar to those observed along continental strike‐slip plate boundaries. Four of the pull‐aparts formed above narrow, subvertical faults extending into the oceanic crust. Within the broad Wharton deformation zone, the significant slip rates (0.8 to 2.5 mm/yr) and unusually large coseismic displacements recorded along F6a suggest that it may be a nascent plate boundary.

Published: March 2020

ABSTRACTThis article evaluates the use of distraction osteogenesis in the treatment of mandibular retrognathia and laterognathia and the long term treatment results of the patients treated with this technique. The procedure was carried out in 5 subjects (3 males and 2 females, mean age 18.4 years) aged between 14 years and 27 years. In patients treated with bilateral mandibular distraction, it was observed that the ANB angle decreased by a mean of 5°, the mandibular corpus length increased by a mean of 14.5 mm and the overjet decreased by a mean of 12.2 mm after treatment. In patients treated with unilateral mandibular distraction, a mean of 3.5° reduction was achieved in ANB angle, the mandibular corpus length increased by a mean of 5.5 mm and a mean of 7 mm correction was achieved in relation to craniofacial midline with treatment. One of these patients showed an increase of 10 mm in ramus height on the affected side and a decrease of 5° in gonial angle whereas the other one showed an increase of 12.5° in gonial angle and an increase of 11 mm in ramus height on the affected side after treatment. The most significant long term relapse was observed in one of the patients treated with bilateral mandibular distraction. Long term relapse seen in the rest of the patients was within clinically acceptable limits. It can be concluded that distraction of the deformed mandible is a feasible and effective technique for treating mandibular retrognathia and laterognathia. However, it must be borne in mind that accurate placement of the distractors and determining the correct distraction vector are crucial factors that have an influence on long term clinical success.

Authors: Kaya Demet , Taner Tulin Ugur 
Published: March 2020

ABSTRACTThe aim of this case report was to present the orthodontic treatment of an adult with spaced dentition, Class III malocclusion, and open-bite tendency. A 28.4-year-old adult woman was concerned about the unesthetic appearance of her spaced dentition localized at both upper and lower arches while smiling. She had a mild tongue thrust, hypertropic upper frenum, and mild speech difficulty while pronouncing “s”. Her profile was straight with prominent lips. Molar relationship was Class III on both sides. Anterior teeth were in an end-to-end relationship. Lower dental midline was deviated to the left side. Cephalometric analysis revealed a skeletal Class III relationship with hyperdivergent facial pattern. The treatment plan included myotherapeutic exercises for the tongue thrust habit and a diagnostic set-up for closure of diastemas. A strict retention protocol was followed combined with gingivoplasty, fiberotomy, and frenectomy procedures. All spaces were closed successfully, adequate overbite and overjet relationships were obtained, and tongue thrust habit and speech difficulty while pronouncing “s” were eliminated. Clinical and cephalometric results indicated the maintenance of the treatment outcome at 6-months post-retention period. (Eur J Dent 2011;5:121-129)

Abstract
Introduction Pectus carinatum (PC) is a congenital chest wall deformity which is characterized by the protrusion of the sternum and costal cartilages. Although orthotic and exercise therapies are commonly offered by physicians for PC treatment, there is a lack of evidence on the benefits of exercises and how long the orthosis should be worn. The aim of this study is to investigate the effects and feasibility of custom-made compression orthosis and exercises in the treatment of PC.
Materials and Methods Patients with PC aged 7 to 17 years old were randomized into three groups: compression orthosis 23 hours, compression orthosis 8 hours, and control group. All groups received exercises for 1 hour a day for 3 weeks. Additionally, compression orthosis 23 hours group wore the orthosis for 23 hours a day, while compression orthosis 8 hours group wore the orthosis for 8 hours a day. PC protrusion, pressure of correction, thorax lateral and anteroposterior parameters, external chest wall measurements, and Nuss Questionnaire were evaluated before and after the treatment. Also, adverse effects, retention, and compliance were assessed. Feasibility was evaluated by calculating the percentages of recruitment, retention, and safety.
Results The compression orthosis 23 hours group showed greater improvements than the other groups. After treatment, all groups showed significant changes in protrusion, pressure of correction, and external chest wall measurements. Adverse events occurred with similar frequency across groups. Retention percentages did not differ among groups.
Conclusion Compression orthosis use for 23 hours can be recommended rather than its use for 8 hours because 23 hours of orthosis use has better correction and similar adverse effects.

This article will summarize the recent advancements in technique and knowledge in the thoracoscopic approach to this challenging neonatal congenital abnormality.
Thoracoscopic Lobectomy for Congenital Pulmonary Airway Malformation: Where Are We in 2019?
Authors: Bonnard Arnaud 
Published: March 2020

AbstractThoracoscopic surgery for congenital pulmonary airway malformation (CPAM) is still a matter of debate and used by approximately 50% of the surgeons in Europe. Several questions need to be addressed about CPAM. The adequate treatment, the surgical approach, and the follow-up are few of them. A review of recent articles published in the literature over the past 5 years is done in trying to respond to these questions. A multidisciplinary team is required to follow these patients since approximately 10 to 15% will develop a chronic lung disease and asthma. In the case of conservative management, computed tomography scan should be perform to monitor the evolution of the CPAM. Minimally invasive surgery should be used whenever possible, although the advantages of pulmonary function tests are not clearly defined, allowing a postoperative fast-track management.

Published: March 2020

AbstractThe surgical management of patients with congenital diaphragmatic hernia (CDH) is challenging and ever changing. It requires the highest expertise not only on the surgical level but also of neonatologists and anesthesiologists. In selected patients traditional open surgery is increasingly replaced by thoracoscopic CDH repair in many centers worldwide. Despite obvious and well-described advantages of the minimally invasive approach like a shorter ventilatory time, less pain, a shorter hospital length of stay, and a better cosmesis, important controversies remain. This review discusses hot topics of minimally invasive CDH repair, such as extracorporeal membrane oxygenation, hypercapnia/acidosis, patch repair, surgical training, and recurrence.

Published: March 2020

Abstract
Introduction Research on esophageal atresia (EA) has been heavily published over the past decades. Herein, we aimed to study the quantity and quality as well as key topics in EA research with regards to global collaborations among countries and authors.
Materials and Methods Publications on EA from 1945 to 2018 were extracted from the Web of Science core collection database. Productivity (quantity) was assessed by the number of publications. Quality was estimated from the number of citations, citation rate per item and year, h-index, and impact index. Collaborative networks were evaluated using VOSviewer. All measures were analyzed for countries, authors, and journals. The 10 most cited original articles between 1969 and 2018 in 5-year intervals (n = 100) were manually screened to assess the key points of EA research.
Results A total of 2,170 publications from 85 countries published in 388 journals were identified yielding 26,755 citations, both significantly increasing over time (p < 0.001). The most productive countries and authors also accounted for high-quality publications and benefited from an active global network. The most productive journals derived from the field of pediatric surgery but accounted only for one-third of EA papers. The best cited journals were unspecific for pediatric surgery. Long-term outcome remained the most important topic in EA research, followed by surgical techniques, epidemiology, associated anomalies, perioperative complications, and postnatal management. In contrast, basic science was underrepresented.
Conclusion Over the past seven decades, EA publications increased tremendously. Productiveness and quality benefited from global networking. Long-term outcome remains the key interest of EA research.
Minimally Invasive Pediatric Surgery: The Learning Curve
Authors: Uecker Marie , Kuebler Joachim F. , Ure Benno M. , Schukfeh Nagoud 
Published: March 2020

AbstractThe use of minimally invasive surgery (MIS) in pediatric patients has increased over the past decades. The process of mastering a new procedure is termed the learning curve, during which the ability to operate increases but poorer outcomes are produced. We aim to analyze the current evidence on learning curves in pediatric MIS and evaluate its impact on patient's clinical outcomes. A systematic literature search was performed for studies listed on PubMed that reported on the learning curve for MIS surgical procedures. Studies were included if they stated the number of procedures required to reach a consistency in outcomes or if they compared outcomes between early and late period of MIS experience regarding the endpoints operative time, conversions, and intra-/postoperative complications. A total of 22 articles reporting on 11 surgical procedures were included in the study. Most authors reported a significant decrease in operative time as well as peri- and postoperative complications with increasing experience of the surgeon. Complications ranged from minor to major, the latter being especially severe for patients receiving pyloromyotomy (5–7% higher risk of mucosal perforation), esophageal atresia repair (15% higher leakage rate and 19–77% higher stenosis rate), or Kasai portoenterostomy (26–35% more liver transplants in the first year after surgery) during the learning curve period. Pediatric MIS comes with a considerable learning curve that may have a significant impact on the patient's clinical outcomes. Efforts should be made to minimize the effect of the learning curve on the patients.
