Authors: Karyakina Irina A. , Rekhviashvili Mikhail G. , Bazina Irina G. , Bogatyreva Nina N. , Propletkina Kristina D.
Published: May 2024

BACKGROUND: Jadassohn's nevus (seborrheic nevus, nevus of the sebaceous glands) is a hamartoma which is mainly localized on the scalp and face skin. At birth, it looks like a barely noticeable light yellow plaque which significantly increases at the puberty period under androgenic stimulation. The histological picture of Jadasson's nevus is characterized by changes in the epidermis in the form of acanthosis, papillomatosis, hyperkeratosis, and a large number of hyperplastic sebaceous glands. Pluripotent epithelial cells, which are part of the hamartoma, may provoke the growth of secondary benign and malignant tumors. This nevus may be manifested by Schimmelpenning–Feuerstein–Mims syndrome which can damage the nervous system and eyes. Currently, there are no uniform recommendations for the management of patients with Jadassohn's nevus.
CLINICAL CASE DESCRIPTION: In this article, we present our own experience of treating two children discussed pathology. The first boy had a radical surgery at the age of 16 days of life because of large dimensions of the nevus and a significant cosmetic defect. Removal of the formation at the neonatal period has prevented the development of rough postoperative scars and promoted good cosmetic outcome due to high elastic and regenerative properties of baby's skin. In the second child, Jadasson's nevus looked like a barely noticeable light yellow plaque; therefore, conservative tactics was chosen for this patient. Both children were consulted by a neurologist and an ophthalmologist who found no pathology in the nervous system and in the vision organs.
CONCLUSION: The described two clinical examples demonstrate the need for individual and multidisciplinary approaches in the management of patients with Jadasson's nevus. Active surgical tactics should be applied because of a significant cosmetic defect rather than for the prevention of malignant transformation which is met in less than 1% of cases.

BACKGROUND: Despite the large number of works devoted to diaphragmatic hernia (DH) in children, this problem is still one of the most pressing in pediatric surgery. Diagnostics and treatment of DH complications still remains one of the most difficult tasks for pediatric surgeons dealing with complications. The most dangerous one is strangulation of the recurrent hernia which leads to stomach and intestine necrosis. Many researchers point out that diagnostics of strangulated diaphragmatic hernia is a difficult issue. One of the reasons for late diagnosis may be physicians' insufficient knowledge on specific features of clinical course of this disease. Intensive development of video endoscopic surgery in pediatric practice contributes to the active implementation of modern technologies on DH treatment, thus leading to much better outcomes.
CLINICAL CASE DESCRIPTION: The authors present a rare clinical case: a 3-day-old child survived thoracoscopic correction of congenital Bochdalek diaphragmatic hernia. After the surgery, paroxysmal abdominal pain and vomiting appears from time to time. The child was treated by various specialists who put various diagnosis: appendicitis, intestinal colic, and gastritis. After this ineffective treatment, the 2-year old child was admitted to the hospital where strangulation of a recurrent diaphragmatic hernia complicated by colon necrosis, perforation of the cecum and peritonitis were diagnosed. The child had a comprehensive management including laparotomy, colon resection with end-to-end anastomosis, plastic surgery of the diaphragm dome, suturing of cecum perforation and sanitation of the abdominal cavity. The postoperative period was without complications. The patient was discharged on day 12 in satisfactory condition. 10 month later, at the follow-up visit, the child was found healthy, no complaints.
CONCLUSION: Strangulated diaphragmatic hernia needs close attention because this pathology can lead to serious complications. Timely diagnostics and surgical treatment of congenital DH promote complete recovery and prevent complications.
Transfusion therapy with allogeneic blood components in children of cardiosurgical units
Authors: Zyuzin Vadim S.
Published: May 2024

The article discusses features of allogeneic blood component transfusion in newborns and infants. This work is primarily addressed to specialists of "non–transfusiological" profile, such as neonatologists, anesthesiologists, intensive care specialists, pediatricians, hematologists and pediatric surgeons. Specific anatomical and physiological structure of child's organism, especially at its neonatologic period, specifies different approaches to the clinical application of donor blood components. However, description of transfusion therapy in children is found only in a small proportion of clinical recommendations, and its legislative level is regulated with an order of the Ministry of Health and the Government decree. Last documents are of administrative nature, and do not help much clinicians in specific decision-making situation. At the same time, transfusion with allogeneic blood is associated with significant complications. The overall prevalence of posttransfusion reactions in children is higher than in adults, and is associated with higher mortality rates. This is especially true for pediatric cardiac surgery. Application of donated blood after cardiopulmonary bypass surgery is associated with postoperative complications such as thrombosis, stroke, acute kidney injury, prolonged mechanical ventilation and death. The authors emphasize the necessity of scientific substantiation of each transfusion with evidence-based medicine. Indications for hemotransfusion have to rely not only on the concentration of hemoglobin and hematocrit, but also on additional physiological triggers. In order to minimize undesirable transfusion reactions and complications, modern technologies should be used to improve the quality of blood components. Attention is focused on modern components of donated blood. The review is aimed to summarize and structure current data on transfusion therapy in pediatric patients. The authors analyse domestic and foreign clinical recommendations and publications. Restrictive and liberal strategies of transfusion therapy are compared. Specific criteria for indications, algorithms for prescription, speed and volume of donor blood component infusion in pediatric units were revealed.

Objective. Autism spectrum disorder (ASD) is characterized by developmental disorders, difficulties in social interaction and communication, and restrictive  and repetitive patterns of behavior. Despite its high prevalence, few studies have been conducted in rehabilitation settings. This study aimed to describe the characteristics of children with ASD from the Pediatric Rehabilitation Service of the Rebagliati Hospital (SRP-HNERM). Materials and methods. Cross-sectional descriptive study. We reviewed the medical records of children under 14 years of age previously diagnosed with ASD from the SRP-HNERM during 2022. Results. A total of 120 children with ASD were evaluated. The median age was 5 years. Most received regular education, but it was inclusive only for 9.8%. The mean age at diagnosis was 3.83 years. We found that 78.4% had no disability certificate and 77.5% of the participantshad incomplete psychological evaluation. The median time since the last physical, occupational and speechtherapy sessions was 3, 8 and 3.5 months respectively. Conclusion. The mean age at diagnosis of ASD was olderthan three years, and more than 75% of the patients had neither a disability certificate nor a complete psychological evaluation. The median time since the last rehabilitation therapy sessions was three months or more. Our findings highlight the need to improve early diagnosis, inclusive education and evaluation and subsequent certification of disability, as well as to establish timely interventions.
Determining Stress Orientation in Rock Valley, Nevada, Using Ambient Seismic Noise
Authors: Delorey Andrew A.
Published: May 2024

The stress field and the mechanical properties of rocks are important to consider for nuclear explosion monitoring due to their effect on seismic wave radiation from earthquakes and explosions. At the Rock Valley Direct Comparison site, the regional orientation of the maximum horizontal compressive stress (SHmax) is well constrained, but it is unknown whether there are local heterogeneities. Here, I show that stress-induced anisotropy in nonlinear elasticity can be used to estimate the orientation of SHmax. Rocks have compliant internal contacts, such as fractures and mineral grain boundaries, that respond to applied strains more strongly than individual mineral crystals. This strain response is asymmetric between compressive and dilatational strains and is affected by anisotropy in the ambient stress field. Traditional seismic velocity measurements are of strain-averaged velocity, which is less sensitive than nonlinear elasticity to the behavior of compliant internal contacts and therefore the stress field and fracture behavior. My results show that the orientation of SHmax measured using ambient seismic noise aligns with regional estimates, with some heterogeneity that can also be explained by the limitations of the seismic array. I demonstrate the potential of a passive technique for monitoring the stress field in places that currently lack local measurements.

Published: May 2024

The transition from the ancient paradigm, where communities were only seen as objects of development, to a new approach that emphasizes community involvement and collaboration with local institutions highlights the importance of empowerment and enriching the quality of communities. This evolution towards community empowerment is paramount for positive societal development in Indonesia, necessitating active participation from the community to attain the desired objectives. This study endeavors to ascertain the correlation between working capital, social capital, and psychological capital in community empowerment programs, as well as to discern which capital plays a more substantial role in empowering the community in Karangasem village. Utilizing a quantitative method, data was collected through questionnaires from 255 community beneficiaries of the empowerment program in Karangasem Village, Sukoharjo, Central Java, Indonesia. Structural Equation Modelling (SEM) was employed for analysis. The research indicates that various forms of working, social, and psychological capital significantly influence community empowerment programs. Working capital emerges as the most influential, with a noteworthy 78% significance, indicating its pivotal role in program implementation. Effective management and allocation of funds are imperative for capital utilization. Social capital, particularly networks, is vital in fostering community empowerment by enhancing internal and external connections. Psychological capital, characterized by optimism, fuels community engagement and commitment to empowerment initiatives, underscoring the importance of internal motivation in program success. These findings may serve as a basis for governmental and empowerment program managers to formulate policies to enhance community welfare.
Lithopedion: the calcified marvel
Authors: Huchappa Anand S. , Raghuveer Karthik , Suresh Anugrah
Published: May 2024

The term lithopedion was derived from the Greek words Lithos and Pedion. It is a rare ectopic pregnancy with incidence as low as 1.5-2.0% of all ectopics. An 80-year old female patient presented to the orthopaedic out-patient department with complaints of lower back pain and mild lower abdominal pain, no history of any trauma. The patient was a known case of Ttype II diabetes and hypertension on medication, no other comorbidities. The patient was referred to the department of radio-diagnosis, for plain radiograph of the lumbo-sacral spine, antero-posterior and lateral view for further evaluation. The plain radiograph revealed a well-defined oval shaped radio-density in the pelvis more towards the right side. Further evaluation was done in the form of ultrasound abdomen and computed tomography. Computed tomography revealed a mummified fetus which is in close proximity to the internal organs and adhering to bowel loop. Low socioeconomic status combined with lack of education of the population are the primary causes for delay in diagnosis resulting in undiagnosed ectopic pregnancy and its later transformation into a Lithopedion.
Uncommon presentation of duodenal gastrointestinal stromal tumor as large paraduodenal cyst: case report
Authors: Kerkar Prashant B. , Sabireen  , Pohekar Monika , Mohanty Mahesh
Published: May 2024

Gastrointestinal stromal tumors (GISTs) are rare solid mesenchymal neoplasms. Small bowel GISTs have predominantly an outward growth and multifocal when associated with neurofibromatosis-1 (NF-1). When the duodenum is involved, lesions may be more challenging if growing towards the pancreas. Their prevalence is unknown, and diagnosis is usually incidental.  Owing to the complex anatomy of the duodenum and pancreatic head, GISTs can be misdiagnosed as pancreatic head tumors, however they presenting as cyst is very rare. Literature shows very few reported cases of cystic GISTS, all arising from the stomach or pancreas where they have been mistaken for pseudocysts or even a mucinous cystadenocarcinoma of the pancreas and only one case of duodenal GIST presenting as cyst has been reported so far. Here, we report a case where investigations including radiology and upper gastrointestinal endoscopy suggested it to be a paraduodenal cyst, but histopathological examination of the specimen resulted in an unexpected diagnosis of GIST. We concluded that non-invasive imaging like CT, MRI, EUS and whenever possible FNA are important for the diagnosis and treatment of GISTs. Surgical resection with clear margin is the desired treatment for a localised duodenal GIST. Also, the feasibility of limited resections such as duodenectomy without pancreatic/ampullary involvement as in our case report where we preserved the pancreas reduces the morbidity and complications associated with extensive surgeries like pancreaticoduodenectomy. Also, Imatinib is an effective therapeutic agent with a remarkable response and prolonged survival.

Background: Despite the medicinal value of the staminate flower of coconut (Cocos nucifera L) there is no data available in the archives for botanical as well as chemical standardisation of flowers of C. nucifera. Aim: Pharmacognostic characters and a phytochemical parameter can be used as a quality standard for authentication of the flower of C. nucifera and detection of adulteration. Methods: Pharmacognostic and phytochemical standardisation of the staminate flower of Cocos nucifera L. was performed as per Ayurvedic Pharmacopoeia of India. It includes studies like morpho-anatomical, powder analysis, preliminary phytochemical evaluation and HPTLC fingerprinting of the flower of C. nucifera. The solvent system in HPTLC studies was Toluene: Chloroform: Ethanol (4:4:1 v/v/v) powder analysis, histochemical test, and preliminary and phytochemical screening were carried out as per standard protocol. Results: Microscopic studies of petal sepals and anther show distinct characteristics that help in the evaluation of the genuine quality of flowers. Physicochemical parameters like loss on drying, total ash, and acid insoluble ash should not be more than 5.58%, 6.8061% and 0.223% respectively. However, water-soluble and alcohol-soluble extractives should not be more than 12.544% and 2.498% respectively. Six prominent bonds of Rf value (0.12, 0.37, 0.48, 0.52, 0.67 and 0.91) were visualised. This Rf value imparts significant quality control data in chromatographic (HPTLC) fingerprinting. Conclusion: Current findings will be helpful in plant authentication, assurance of quality and adulteration detection for staminate flower of C. nucifera.

Published: May 2024

The purpose of this work was to explore and compare the phytochemical constitution, vitamin composition, antioxidant activity, and antimicrobial potential of leaf extracts from two Ethnomedicinal plants, Eupatorium glandulosum and  Eupatorium odoratum, belonging to family Asteraceae collected from the Eastern Himalayan Darjeeling region and the plains of Jhargram in West Bengal, India. Four distinct solvents viz., 80 % aqueous ethanol, ethyl acetate, chloroform and n-hexane were used to prepare the leaf extracts. The identification and quantification of phytochemicals and water-soluble vitamins was conducted through HPLC. To evaluate antioxidant potential, 2,2-Diphenyl-1-picryl hydrazyl (DPPH), 2,2-azino-bis-3-ethylbenzothiazoline-6-sulphonic acid (ABTS), and Ferric Reducing Antioxidant Power (FRAP) assays were performed. The antimicrobial activity was investigated against Streptocococcal strains (S. oralis, S. mutans, S. pyogenes). Both the plants exhibited a diverse array of identified phytochemicals. E. glandulosum contained five while E. odoratum presented an even richer composition of seven water-soluble vitamins. Remarkably, E. odoratum displayed the highest scavenging activity against DPPH radicals (70.08%), and notable reducing potential (10.74 AAE mg/gm). In contrast, E. glandulosum showcased pronounced scavenging potential against ABTS radicals (74.32%). Additionally, the ethyl acetate extract from E. odoratum displayed robust antimicrobial efficacy against, S. oralis, inducing an inhibition zone of 16.00 mm ± 2.82 while E. glandulosum exhibited an inhibition zone of 11.50 mm ± 0.707. These findings validate the therapeutic potential and ethnomedicinal use of these plants.

The brief survey of problems accompanying the reconstruction of dynamical equations from chaotic time series is presented. The most frequently used procedures of reconstruction are described, including estimate for the dimension of a system, choice of the equation type, determination of parameters of nonlincar functions by means оf differential equation fitting to time series, deleting of unreliable coefficients, testing of global stability of the reconstructed system. Several examples of reconstruction are presented. New effective criterium for distinguishing dynamical and random processes is suggested, based оп the notion of degree of predictability. Principal limitations are pointed out imposed by the properties of instability in presence of noise оп time-interval of predictable behaviour («horizon of predictability»), on the length of a sample, on amount of coefficient to be determined. So named «discriminant» (two window) approach is outlined, which allows to reveal nonstationarity in dynamical system, and important role of low dimensional models for retrieval of nonstationarities in systems of higher dimension is discussed. In conclusion prospective areas of applicability of reconstruction procedures are pointed out.

The nonlinear dynamics of the cylindrically symmetric high—frequency discharge produced by а circular polarized electric field is considered. Three main stages of discharge evolution are analyzed by computer simulation. These stages are е following: (i) self—acceleratlng avalanche—like process which develops up to plasma density maximum corresponding to «geometric» resonance of the plasma cylinder; (ii) diffusion propagation of the fast ionization wave which contains the plasma resonance region at its leading edge; (iii) transition to the steady—state. The sharpening regimes for the field amplitude and plasma density profiles in the vicinity of the plasma resonance point at the axes are analyzed. The arising dynamic structures are found to be in a good agreement with the self-similar solution defined for the electric field and plasma density nonlinear equation set.
James Clerk Maxwell
Authors:   Kurchatov Institute, Danilov Yulii
Published: May 2024

He was born the same year that Michael Faraday discovered electromagnetic induction. Subsequently, he translated into the language of differential equations, familiar to physicists since the time of Newton and Leibniz, the picture of space permeated by the lines of force of electric and magnetic fields, which the great experimenter saw with his inner vision. Grateful descendants forever associated his name with his deduced electromagnetic field equations, amazed by their depth and courage of his thought, admired their beauty. Ludwig Boltzmann prefaced his lectures on these equations with an epigraph from his favorite Schiller: "Did God write these lines?" The man in question has left a deep trace in all areas of physical science, which he managed to touch during his bright, full of magnificent achievements, but - alas! - so short life: in the theory of elasticity, statistical mechanics, the kinetic theory of gases and, as already mentioned, the theory of the electromagnetic field. Ero's name was James Clerk Maxwell. (The Scots pronounce his name somewhat differently: James Clark Maxwell, but we will follow the historically established in Russian literature transcription of the great name).

Authors: Isabella ‎ , Nofrima Sanny
Published: May 2024

Radicalism has become a serious threat in Indonesia, especially through the spreading of extreme ideologies through social media and online platforms. This threat is increasingly pervasive with the rise of radical propaganda, which can be easily accessed by the public, especially through Twitter. Therefore, this research has the main objective, namely identifying the urgency of the threat of radicalism propaganda in cyberspace and analyzing the important role of digital literacy as an effective prevention tool. The thematic analysis method is used to examine radical content spread on Twitter, using the Nvivo 12 Plus tool to support the data analysis process. The findings of this research highlight the importance of increasing digital literacy in society as a strategic step in facing the growing threat of radicalism. Digital literacy has an important role in equipping individuals with the ability to identify, analyze, and counter harmful content and actively participate in reporting such threats to the authorities. In this case, the government’s active support in holding digital literacy education programs and awareness campaigns is crucial. We can create a safer and smarter digital environment with close cooperation between all parties.

The Influence of Leadership and Performance of Village Government Bureaucracy and its Implications for the Quality of Public Services Towards Industrial Revolution 4.0 in Banyuasin Regency South Sumatra Province
Authors: Putra M. Defri Adi Shah
Published: May 2024

Environmental changes and developments that continue to develop in this century have caused uncertainties due to the development of information technology. These increasingly complex changes encourage various societal demands and increasingly tighter and sharper competition. This condition has led to pressure on the government to make changes in various sectors, especially public services toward Industrial Revolution 4.0 in the village government system. This research aims to analyze and test the partial influence of leadership and performance of the village government bureaucracy on the quality of public services toward the Industrial Revolution 4.0. This research design uses quantitative methods through a questionnaire survey, which will be tested for validity and reliability. The findings in this research indicate that the quality of leadership is still unsatisfactory, which causes the village government’s performance to be suboptimal, which results in the quality of service to the community in the era of increasingly developing information technology. Therefore, there is a need for leadership and performance transformation to improve the quality of technology-based services to society.

Currently, there is a critical situation of high matter of water-soluble nitrogen compounds in water bodies of developed countries. In world practice, it is believed that the most promising method for removing nitrogen compounds from wastewater is anammox technology based on the biochemical process of oxidizing ammonium with nitrite under anoxic conditions. Bacterial anammox is based on the reaction between nitrite ion and ammonium ion, which converts them to molecular nitrogen. However, anammox bacteria are characterized by a low growth rate and require specific growing conditions. As an alternative to the bacterial anammox technology, there is proposed a technology of plasma microwave-discharge synthesis of nitrite ions NO2– from air, carried out in a microwave plasma in a magnetron-type plasmatron for purifying waste water from water-soluble compounds of reaction nitrogen. The unique possibilities of non-equilibrium low-temperature plasma, as a medium for chemical reactions, and, in particular, in microwave plasma, are the basis of new promising technologies. Under the conditions of microwave discharge turbulence, ionized molecules of nitrogen N2+ and oxygen O2–, approaching each other, interact, it triggers an avalanche-like cascade of reactions with the formation of two molecules of nitrogen monoxide NO, which is starting for the transition from the electron shock stage of plasma chemical reactions to the stage of avalanche-like photolytic synthesis of nitrogen oxides NOx. Based on the results of studying the concentration of the final products of plasma chemical reactions in the microwave discharge zone, the synthesis of nitrite ions of NO2– is predominant. Experimental studies were carried out on the effect of the NO2– nitrite ion stream obtained at the plasmatron outlet on a model solution of ammonia hydrate (NH4OH) at a concentration of 150 mg/l. The most optimal was the time of exposure of ionized gas to the model solution for 5 minutes, while the efficiency of removing ammonium ions was 99.83%. Thus, plasma microwave-discharge synthesis of nitrite ions NO2– can be an alternative to biological anammox technology and is characterized by simple and compact installation.
Neonatal Hypoglycemia

Neonatal hypoglycemia (NH) is broadly defined as a low plasma glucose concentration that elicits hypoglycemia-induced impaired brain function. To date, no universally accepted threshold (reference range) for plasma glucose levels in newborns has been published, as data consistently indicate that neurologic responses to hypoglycemia differ at various plasma glucose concentrations. Infants at risk for NH include infants of diabetic mothers, small or large for gestational age, and premature infants. Common manifestations include jitteriness, poor feeding, irritability, and encephalopathy. Neurodevelopmental morbidities associated with NH include cognitive and motor delays, cerebral palsy, vision and hearing impairment, and poor school performance. This article offers a timely discussion of the state of the science of NH and recommendations for neonatal providers focused on early identification and disease prevention.

This article investigates the pivotal role of innovations in human capital in propelling sustainable socioeconomic development and transition to green energy technologies within the energy sector. Recognized as the linchpin of modern economies, the energy industry provides essential resources critical for industrial processes, transportation, and the overall functioning of society. Amid the global transition toward sustainable practices, the importance of not only advancing technological innovation but also enhancing human capital in this sector is increasingly acknowledged, especially in the light of the shift toward green and renewable energy alternatives. Employing a bibliometric approach, this study analyzes a collection of 1933 documents, encompassing research articles, conference papers, and book chapters, indexed in the Web of Science (WoS) database. Through a network cluster analysis of the textual and bibliometric data using the VOSviewer software, our findings suggest that investments in human capital are deemed crucial for fostering long-term sustainable economic growth within energy companies globally. Furthermore, the significance of human capital in the energy sector is observed to be escalating in prominence among researchers and academics, both within Russia and internationally. This growing interest underscores the vital role that skilled, knowledgeable, and innovative human resources play in navigating and driving the energy sector toward a more sustainable and renewable future.
