The baryon cycle of Seven Dwarfs with superbubble feedback
Authors: Mina Mattia , Shen Sijing , Keller Benjamin Walter , Mayer Lucio , Madau Piero , Wadsley James
Published: July 2021

We present results from a high-resolution, cosmological, ΛCDM simulation of a group of field dwarf galaxies with the “superbubble” model for clustered SN feedback, accounting for thermal conduction and cold gas evaporation. We compared our results to a previous simulation which has the same initial condition and galaxy formation physics (other than SN feedback), but adopts a delayed-cooling model for supernova. The simulated luminous galaxies have blue colors, low star formation efficiencies and metallicities, and high cold gas content, reproducing the observed scaling relations of dwarf galaxies in the Local Volume. Bursty star formation histories and superbubble-driven outflows lead to the formation of kpc-size dark matter (DM) cores when stellar masses reaches M* > 106 M⊙, similar to previous findings. However, the superbubble model appears more effective in destroying DM cusps than the delayed-cooling model in the previous study, reflecting a higher coupling efficiency of SN energy with the ISM. On larger scale, superbubble-driven outflows have a more moderate impact: galaxies have higher gas content, more extended stellar discs, and a smaller metal-enriched region in the circumgalactic medium (CGM). The two halos with Mvir ∼ 109 M⊙, which formed ultra-faint dwarf galaxies with the delayed-cooling mode, remain dark due to the different impact of metal-enriched galactic winds from two nearby luminous galaxies, indicating that the formation of faint dwarfs is highly dependent on feedback and environmental effects. The column density distributions of H I, Si II, C IV and O VI as a function of the scaled impact parameter (b/Rvir) are in good agreement with recent observations of CGM around isolated dwarf galaxies. While H I is ubiquitous with a covering fraction of unity within the CGM, low and intermediate ions like Si II and C IV are less extended (typically confined within 0.2 − 0.3 Rvir), and non-detections are common. O VI is more extended with column density N(O VI) ≳ 1013.5 cm−2 within Rvir, but its mass is only 11% of the total CGM oxygen budget, as the diffuse CGM is highly ionised by the UV background. Superbubble feedback produces C IV and O VI column densities that are an order of magnitude higher than those in the previous study using delayed-cooling feedback. Thus, the CGM and DM cores are most sensitive probes of feedback mechanisms.
Confirming NGC 6231 as the parent cluster of the runaway high-mass X-ray binary HD 153919/4U 1700-37 withGaiaDR2
Authors: van der Meij Vincent , Guo Difeng , Kaper Lex , Renzo Mathieu
Published: July 2021

Context.A significant fraction (10–20%) of the most massive stars move through space with a high (v ≳ 30 km s−1) velocity. One of the possible physical explanations is that a supernova in a compact binary system results in a high recoil velocity of the system. If the system remains bound, it can be subsequently observed as a spectroscopic binary (SB1), a high-mass X-ray binary, a compact binary, and finally a gravitational-wave event.

Aims.If such a system is traced back to its parent cluster, binary evolution models can be tested in great detail.

Methods.TheGaiaproper motions and parallaxes are used to demonstrate that the high-mass X-ray binary HD 153919/4U 1700-37 originates from NGC 6231, the nucleus of the OB association Sco OB1.

Results.The O supergiant and its compact companion, of which the physical nature (a neutron star or a black hole) is unknown, move with a space velocity of 63 ± 5 km s−1with respect to NGC 6231. The kinematical age of the system is 2.2 ± 0.1 Myr. The parallaxes and accurate proper motions inGaiaDR2 were used to perform a membership analysis of NGC 6231; 273 members are identified, of which 268 have good quality photometry. The distance to NGC 6231 is 1.63 ± 0.15 kpc. Isochrone fitting results in an age of 4.7 ± 0.4 Myr and an extinctionAVto the cluster of 1.7 ± 0.1. With the identification of NGC 6231 as the parent cluster, the upper limit on the age of the progenitor of 4U1700-37 at the moment of the supernova explosion is 3.0 ± 0.5 Myr.

Conclusions.With these constraints, the evolutionary history of the system can be reconstructed with an initial mass of the progenitor of the compact object > 60M⊙. The high mass, the extreme mass ratio, and short orbital separation of the system make it difficult to produce possible progenitor systems through population synthesis. We propose that the system experienced a Case A mass transfer phase before the supernova, which typically widens a binary. In order to create a progenitor system that does not merge, a lot of angular momentum must be lost from the system during the phase of mass transfer and/or an asymmetry in the supernova explosion provides a kick resulting in the observed orbital parameters. Given its current high space velocity and the derived evolutionary history, the compact object in the system is more likely to have received a large natal kick, which suggests that it is more likely a neutron star than a black hole. HD 153919/4U1700-37 might be a prototype in the Milky Way for the progenitor of gravitational wave events such as GW190412.
EC 22536−5304: a lead-rich and metal-poor long-period binary
Authors: Dorsch M. , Jeffery C. S. , Irrgang A. , Woolf V. , Heber U.
Published: July 2021

Helium-burning hot subdwarf stars of spectral types O and B (sdO/B) are thought to be produced through various types of binary interactions. The helium-rich hot subdwarf star EC 22536−5304 was recently found to be extremely enriched in lead. Here, we show that EC 22536−5304 is a binary star with a metal-poor subdwarf F-type (sdF) companion. We performed a detailed analysis of high-resolution SALT/HRS and VLT/UVES spectra, deriving metal abundances for the hot subdwarf, as well as atmospheric parameters for both components. Because we consider the contribution of the sdF star, the derived lead abundance for the sdOB, + 6.3 ± 0.3 dex relative to solar, is even higher than previously thought. We derive Teff = 6210 ± 70 K, log g = 4.64 ± 0.10, [FE/H] = − 1.95 ± 0.04, and [α∕Fe] = + 0.40 ± 0.04 for the sdF component. Radial velocity variations, although poorly sampled at present, indicate that the binary system has a long orbital period of about 457 days. This suggests that the system was likely formed through stable Roche lobe overflow (RLOF). A kinematic analysis shows that EC 22536−5304 is on an eccentric orbit around the Galactic centre. This, as well as the low metallicity and strong alpha enhancement of the sdF-type companion, indicate that EC 22536−5304 is part of the Galactic halo or metal-weak thick disc. As the first long-period hot subdwarf binary at [FE/H] ≲− 1, EC 22536−5304 may help to constrain the RLOF mechanism for mass transfer from low-mass, low-metallicity red giant branch (RGB) stars to main-sequence companions.
Optimal reinsurance and investment strategies for an insurer under monotone mean-variance criterion
Authors: Li Bohan , Guo Junyi
Published: July 2021

This paper considers the optimal investment-reinsurance problem under the monotone mean-variance preference. The monotone mean-variance preference is a monotone version of the classical mean-variance preference. First of all, we reformulate the original problem as a zero-sum stochastic differential game. Secondly, the optimal strategy and the optimal value function for the monotone mean-variance problem are derived by the approach of dynamic programming and the Hamilton-Jacobi-Bellman-Isaacs equation. Thirdly, the efficient frontier is obtained and it is proved that the optimal strategy is an efficient strategy. Finally, the continuous-time monotone capital asset pricing model is derived.

Authors: Vinokur Inna , Ponomareva Svetlana
Published: July 2021

The paper presents an innovation-oriented model of resource management, which was built on the basis of the methodology of economic assessment of resource capabilities of contracting companies of the oil and gas industry. Assessment and choice of resource capabilities of contracting companies is the most important scientific problem of large companies and enterprises of the oil and gas industry when purchasing material resources. Currently, the increase in the supply of the same type of resources exacerbates the problem of choice. Thus, a large number of algorithms, methods and other procedures were developed to select organizations that supply resources. However, there are not enough comprehensive tools to assess the feasibility of selecting a supplier taking into account factors that allow evaluating suppliers of a certain industry. The purpose of the study is to create an innovative resource management model based on the methodology of economic justification for choosing resource suppliers for oil and gas enterprises. The object of the study is enterprises and large companies of the oil and gas industry. The subject of the study is effective resource management based on the methodology of economic assessment of the resource capabilities of contracting companies.

The authors 'conclusions support the fact that the effectiveness of public management could be determined by the level of management passionarity.
Assessing the decoupling of economic growth from environmental impacts in industrial regions of the Russian Federation: an impact decoupling approach
Authors: Pepelyaeva Anna , Krutova Aleksandra
Published: July 2021

The article analyzes the dynamics of the economic activity level in Russian industrial regions and its impact on the main environmental elements (water, air and soil) by calculating the decoupling coefficient. In the study a hierarchical cluster analysis was carried out, resulted in the formation of seven regional clusters, five of which had a significant share of the industrial sector in the gross value-added structure. Decoupling coefficients were calculated for 64 constituent entities of the Russian Federation belonging to different types of industrial clusters. The ecological and economic balance assessment of industrial regions growth showed the decoupling effect presence for most of them. The movement towards environmentally sustainable growth is more evident in the regions of the industrially diversified cluster. The analysis of three decoupling coefficients showed that in the vast majority of industrial regions the growth rates of pollutant emissions into the atmosphere and the growth rates of polluted wastewater discharges into surface water change at a lower rate than per capita GRP, which indicates a “green trend” in the region’s economic activity. However, the decoupling coefficient, showing the dynamics ratio of production and consumption waste and GRP per capita, has negative value in 37.5% of regions. The most problematic one in terms of this indicator was the Trade and manufacturing cluster, including 21 constituent entities of the Russian Federation. According to the authors, it may be related to the trade sector of these regions.

Expenditures for innovations and foreign direct investments in Bulgaria - regional aspects, features and trends
Authors: Petrova Mariana , Radukanov Sergey
Published: July 2021

The study examines the costs of innovation and foreign direct investment by district (NUTS 3), Planning regions (NUTS 2) and Regions (NUTS 1), according to the classification of territorial units for statistical purposes. The main trends in their development are outlined. The authors believe that foreign direct investment is closely linked to the cost of innovation. Of particular importance is the view that the intensity of R&D expenditure by statistical regions and districts almost coincides with foreign direct investment. The results of the analysis confirm the strong disproportion in recent years in the distribution of direct investment and R&D expenditures, which leads to the formation of a highly developed center - Sofia district (capital) and weak periphery - all other districts.

Management of digital transformation of industrial enterprises based on maturity models
Authors: Malysheva L. A. , Kharlamova O. G.
Published: July 2021

This paper considers the issues of the implementation of the digital transformation of industrial enterprises: the analysis of the existing model (AS IS) and planning the desired model (TO BE), depending on different conditions. The authors present the existing business models of digital transformation, reveal different approaches to classification, as well as their drawbacks from the point of view of practical application. In general, the models can be applied to diagnostics, but not to planning the desired state. The principle of classification of transformation models based on the life cycle of the market is proposed: monopoly, oligopoly, competition and monopsony. Firstly, the life-cycle approach allowed applying the author’s Dynamic Model of Changes in Corporate Strategies (Dynamics) to digital transformation. This model was proposed earlier for the classification of traditional business models. Secondly, the life-cycle approach allowed using the maturity models of the industry, strategies, product, processes, data etc. in order to build a planning algorithm for the desired business model. As a result of the lifecycle approach to the classification of business models, it was possible to develop an algorithm for diagnosing and planning the desired digital transformation model, taking into account the limitations of maturity levels and present it in the form of a Digital Dynamic Model of Corporate Strategy Changes (Dynamics).

Published: July 2021

The article presents the results of the analysis of the problem of creativity and creative work in children with disabilities having different impairments. This research serves as a basis for conducting a separate study aimed at researching the peculiarities of the search for creative solutions in the process of completing figure drawings in younger schoolchildren with hearing impairments compared to their peers with normal hearing. For this purpose, a comparative analysis of the drawings of hearing-impaired students and elementary school students with preserved hearing was conducted by the criteria of fluency, flexibility, elaborateness, and originality. The need for the present study is determined by the tasks of the modern system of special and inclusive education aimed at the optimal personal development of all children and the creation of psychological and pedagogical conditions for the successful development of different types of creative activity that positively affect their socialization. The study uses a set of theoretical and empirical methods of analysis of the studied problem, as well as a comparative study of general and specific features of creativity in children with preserved and impaired hearing. These specific features are determined by a disproportionate formation of different types of thinking, a delay in the development of figurative memory, verbal speech, and imagination in comparison with hearing children. The novelty of the study consists in the expansion of knowledge about the potential possibilities of creative decisions and creative abilities of persons with developmental disorders at different ages in special psychology and pedagogics. The results of the study of creativity of children with hearing impairments can be used in the educational system for professional orientation and creating conditions for persons with special educational needs to master creative professions.

Authors: Suhonosov Alexander Petrovich , Karneev Raphael Camilievich , Kurganova Elena Anatolievna , Listick Elena Marikovna
Published: July 2021

The paper reveals some aspects of the problem of forming a complex of qualities that characterize the phenomenon of creative leadership in school students. The interest in this problem is explained by the increased need of modern Russian society and its relevance in scientific psychological and pedagogical and socio-psychological problems. The prerequisite for the study was the contradiction between the urgent need for creative leaders in various spheres of production, management, in creative and spiritual life and the absence of a systematic purposeful state policy in this field. At the same time, it is stated that if in foreign science from the beginning of the 1960s, studies of the concept of creative leadership are carried out, but in Russian scientific thought, the concept of creative leadership is still poorly understood from the point of view of its formation. Several aspects of the problem of leadership are reviewed, such as the ability of a leader to lead other people to solve various problems, including creative ones; the concept of creativity is analyzed as the ability to think in an original, non-standard, creative way, to generate innovative cultural products. The phenomenon of creative leadership is considered by the authors, first of all, as a person’s expressed ability to lead a group of people to achieve various goals that are important for this group, to implement creative ideas and projects, while the directions, methods, means of their implementation are innovative. The paper presents the results of an experimental study conducted to determine the nature of the relationship between creative leadership and creative thinking. The novelty of the study is determined by the use of an original series of methods that allow for a comprehensive assessment of the formation of creative leadership in school students and the presence of a correlation between the indicators of the creative leadership methodology with various factors characterizing creative thinking.
Animation creativity as a factor in the development of children’s giftedness
Authors: Murodhodjaeva Natalia Sergeevna , Averin Sergey Alexandrovich , Koptelov Andrey V. , Karpova Svetlana Ivanovna , Sukhova Elena Ivanovna
Published: July 2021

The main premise of the study is the objective need to find new means for the development of children’s personality in the modern educational process. Scientific and technological progress, the active use of technology and gadgets by children, even young children, the expansion of the use of distance learning and communication, artificial intelligence, and social networks are the realities in which we already live. Therefore, high relevance is gained by the means that are based on information technologies on the one hand but have the potential for the development of children’s personality on the other. What can be considered as one such instrument is animation creativity of children that involves the process of children jointly composing, creating, and discussing a cartoon of their own making. The assumption of the potential effectiveness of animation creativity as a means of developing children’s giftedness is based on the fact that in the process of joint creation of a cartoon, children show and develop several abilities as they create the script, images of characters, their characters and appearances, as they are involved in filming, montage, editing, as well as the presentation and promotion of the finished animated film. Children interact with one another and with technical devices, learn to listen to and hear each other, substantiate their opinion, carry the responsibility for collective work, distribute responsibilities between each other, and bring the creative idea to fruition in the finished product. The goal of the study is to conduct an empirical study to determine the effect of the author’s children’s animation technique on the development of figurative thinking in older preschool-age children. Methods: observation, conversation, measurement, creative tasks, comparative analysis of experimental data.

Authors: Borovskikh Tatiana Anatolyevna , Bakhareva Slavyana Rostislavovna , Feshchenko Irina Alekseevna
Published: July 2021

The prerequisite for the present study is the lack of instruments ensuring timely identification and development of school students’ giftedness in natural science disciplines in the arsenal of a modern teacher. A system of creative tasks integrated into the process of studying chemistry and biology can largely contribute to the development of subject-related knowledge and creative thinking. However, the integration of creative tasks in the educational process should be preceded by purposeful formation and monitoring of the development of a set of reproductive intellectual skills. The main goal of the study is to develop a method for the identification and development of students’ abilities including giftedness in chemistry and biology, as well as to study the opportunities for creating individual learning trajectories in natural science disciplines. The study is based on the hypothesis that the development of an individual trajectory in studying chemistry and biology will contribute to the development of individuality and the creative abilities of students. The main method used in the study is determining the speed of completion of logical operations in the process of solving cognitive tasks. Assessment of the speed of completion of logical operations allows determining, among other things, the ability for mastering natural science disciplines and a child’s giftedness in this educational sphere. A system of tasks and exercises in chemistry and biology providing for the study of the speed of development of reproductive and creative thinking and allowing real-time monitoring of the effectiveness of the educational process for its timely correction is developed for the first time. The results of the study of the speed of completion of logical operations by a student in the process of solving cognitive tasks presented graphically form the basis for the development of an individual program of development of intellectual and creative abilities of a child.
Reflexive and project-based forms of psychological and anthropological practice of developing creativity in children
Authors: Kovaleva Natalia B. , Dyakonova Аnastasiya I.
Published: July 2021

The article deals with the possibilities of reflexive and project-based forms of anthropological practice which make it possible to create an environment for the development of the individual’s creative orientation and creativity in the context of the modern media environment. The authors focus on the design and testing of innovative technologies in the field of humanities in the rapidly changing conditions of children and adolescents who are growing up in the digital environment of the 21st century. The specific features of the media environment in terms of determining the anthropological imperative of the educational prototype are examined. Based on theoretical and practical developments, the principles of deploying such technologies in the format of educational anthropological practices are demonstrated. The authors substantiate the resource potential of co-creative forms of psychological and pedagogical anthropological practice based on the original reflexive-positional approach to the personal development of children in primary and secondary school. The emphasis is on the presentation of two reflexive-positional technologies that have proven their practical efficiency/ These technologies are based on the principles of project reflection, namely, plot and activity-based game and mediahermeneutics. The principles of creating a transformative socio-cultural educational environment that initiates the development of giftedness and creativity of children and adolescents in mediahermeneutics technologies are described in detail. The authors provide the results of a comprehensive study of the personality and creativity development among children and adolescents based on reflexive and project-based technologies of psychological and pedagogical anthropological practices to identify the relationship between the personal and creative development of children and adolescents participating in programs built using mediahermeneutics. The discussion of the results allows one to conclude that project-based and reflexive forms of anthropological practice, when properly organized, in particular using the principles of mediahermeneutics, contribute to the development of spiritual value orientations, creative focus, cognitive and aesthetic motivation and create the environment for the manifestation of adolescent giftedness.

Modern education is meant to create conditions for the development and self-development of learners’ personalities. This task can only be achieved by teachers who aim for creative professional self-fulfillment and self-enhancement; therefore, in the context of global changes the issue of self-design carried out by the subject of teaching activity and development of their personal potential is gaining new significance. The prerequisites for this research are determined by the necessity and possibility for involving young teachers in pedagogic creativity, which helps them to enter the profession successfully. Meanwhile, there are quite a few obstacles to teachers’ creative self-fulfillment; at the stage of entering the profession and adaptation to it, there is a gap between the potential and actual action. The objective of this research is to identify the value and conceptual orientation of personality and find out the reasons preventing creative self-fulfillment and goal commitment among teachers at the stage of entering the profession. A total of 30 teachers working at Moscow schools ages 25 to 35 took part in the empirical research. Methods: coaching techniques, written survey (empirical questioning), and content analysis of mini-essays. It has been found that creative self-fulfillment is possible if there is a connection between professional devotion, personal success, and clear goal commitment of a teacher. The obstacles on the way to self-fulfillment include a set of unjustified personal restrictions, “hidden” positive ideas of oneself and one’s individual abilities, misbalance between personal beliefs and value-conceptual orientations as well as inactivity and exaggeration of external, environmental, or interpersonal barriers. “Reloading” of a teacher is possible if they focus their goals on the future and support such commitment with internal freedom and awareness of their potential and creativity.

Das Lymphgefäßsystem ist essenziell für den Rücktransport interstitieller Flüssigkeit aus dem Gewebe zurück in den Blutkreislauf. Bei Störungen des komplexen Netzwerkes kommt es zur Ausbildung von Ödemen und der Ansammlung und Ablagerung von Proteinen und Lipiden in der betroffenen Region. Obwohl das Lymphsystem schon seit Jahrhunderten Gegenstand der Forschung ist, haben lymphologische Krankheitsbilder wie das Lymphödem als mögliche Folge onkologischer Therapien erst in den vergangenen Jahren an Aufmerksamkeit gewonnen. So liegt die Inzidenz des sekundären Lymphödems, das durch traumatische, infektiöse oder iatrogene Schädigung auftritt, zwischen 0,13 und 2 % und betrifft meist Frauen. Auch das davon abzugrenzende Lipödem ist in den letzten Jahren zunehmend in den Fokus der Öffentlichkeit gerückt. Beide Erkrankungen können mit einer schmerzhaften Umfangsvermehrung, einer beruflichen und alltäglichen Einschränkung und einer Reduktion der Lebensqualität einhergehen. Neben der klinischen Untersuchung und Anamnese gewinnen neue bildgebende Verfahren eine zunehmende Bedeutung zur Verbesserung der Diagnosestellung, Stadieneinteilung und Therapieplanung, wenngleich immer noch oftmals Monate bis Jahre bis zur korrekten Diagnosestellung vergehen. Während konservative Therapiemethoden wie die komplexe physikalische Entstauungstherapie weiterhin die Grundlage der Behandlung bilden, kommen zunehmend auch operative Verfahren bei der Therapie des Lymphödems zum Einsatz. Hierbei unterscheidet man die reduzierenden Verfahren, die hauptsächlich auf die Symptomreduktion abzielen, von den rekonstruktiven Verfahren zur Wiederherstellung des Lymphsystems mittels mikrochirurgischer Techniken. Nachfolgend werden verschiedene operative Therapiemöglichkeiten in der Lymphologie dargestellt.

A Rh-catalyzed aryl migratory/decarbonylation of unstrained ketones has been developed. This viable transformation provides a complementary decarbonylative method using diaryl ketones to afford a variety of alkenylated heterocycles in good yields with moderate to good stereoselectivity and broad substrate scope. The synthetic utility of this protocol is also demonstrated by the conversion of the alkenylated heterocycles to tetrahydrocarbazole derivatives.

Introduction The increase in intracranial pressure (ICP) is a neurological complication resulting from numerous pathologies that affect the brain and its compartments. Therefore, decompressive craniectomy (DC) is an alternative adopted to reduce ICP in emergencies, especially in cases refractory to clinical therapies, in favor of patient survival. However, DC is associated with several complications, including hydrocephalus (HC). The present study presents the results of an unusual intervention to this complication: the implantation of an external ventricular drain (EVD) in the intraoperative period of cranioplasty (CP).

Methods Patients of both genders who presented with HC and externalization of the brain through the cranial vault after decompressive hemicraniectomy and underwent EVD implantation, to allow the CP procedure, in the same surgical procedure, were included.

Results Five patients underwent DC due to a refractory increase in ICP, due to automobile accidents, firearm projectiles, falls from stairs, and ischemic strokes. All evolved with HC. There was no uniform time interval between DC and CP. The cerebrospinal fluid (CSF) was drained according to the need for correction of cerebral herniation in each patient, before undergoing cranioplasty. All patients progressed well, without neurological deficits in the immediate postoperative period.

Conclusion There are still several uncertainties about the management of HC resulting from DC. In this context, other CP strategies simultaneous to the drainage of CSF, not necessarily related to ventriculoperitoneal shunt (VPS), should be considered and evaluated more deeply, in view of the verification of efficacy in procedures of this scope, such as the EVD addressed in this study.
Infantile Galactosialidosis with Novel Mutation: An Early Presentation

Galactosialidosis (GS) is a rare lysosomal storage disorder. We reported here, the case of a 29-day-old boy who had increased body swelling, difficulty breathing, and petechiae on the trunk since birth. The antenatal history was unremarkable. Clinical laboratory findings included coarse facies, hepatosplenomegaly, gross ascites, thrombocytopenia, nephrotic range proteinuria, and bilateral hydronephrosis. The diagnostic challenge was resolved after genetic testing, which revealed GS with a novel homozygous c.1158dupA mutation.

Aim The aim of this study was to detail the neurodevelopmental profile of subjects affected by ocular albinism (OA) and to collect data on GPR143 gene analysis.

Design The design of the study involves a retrospective longitudinal observational case series.

Methods We collected data on the neurodevelopmental profile of 13 children affected by OA from clinical annual assessments conducted for a period of 6 years after the first evaluation. We described visual profile, neuromotor development and neurological examination, cognitive profile, communication and language skills and behavioral characteristics. The GPR143 gene analysis was performed as well.

Results Children presented a variable combination of ocular and oculomotor disorders unchanged during the follow-up, a deficit in visual acuity and in contrast sensitivity that progressively improved. Abnormalities in pattern visual evoked potential were found. No deficits were detected at neurological examination and neuromotor development except for a mild impairment in hand-eye coordination observed in five cases. A language delay was observed in five cases, two of whom had also a developmental quotient delay at 2 years evolving to a borderline/deficit cognitive level at preschool age, difficulties in adaptive behavior and autistic-like features were found. Mutations in the GPR143 gene were identified in the two patients who presented the most severe clinical phenotype.

Conclusion Children with OA may share, in addition to a variable combination of ocular signs and symptoms, a neurodevelopment impairment regarding mostly the cognitive, communicative, and social area, especially those with GPR143 mutation.
