Published: December 2020

Background: Fractures of the acetabulum are serious because they affect a deep, load-bearing joint that is difficult to repair surgically at first. They occur in a context of polytrauma. The aim of our work is to study the epidemiological, lesional, therapeutic and evolutionary aspects of acetabulum fractures.

Methods: This is a 5-year retrospective study from January 2012 to December 2016 including 45 patients treated for acetabulum fracture.

Results: 45 patients including 38 men and 7 women with a mean age of 36 years (extremes 18 and 74). The circumstances of occurrence were dominated by road traffic accidents with 42 cases (93.3%).

According to the Judet-Letournel classification, we observed 28 elementary fractures (16 posterior wall fractures, 11 posterior column fractures, 1 anterior column fracture) and 17 complex fractures (7 posterior column and posterior wall fractures, 6 transverse and posterior wall fractures, 3 posterior and anterior column fractures, 1 anterior column and posterior hemi-transverse fracture). The association of a dislocation with an acetabulum fracture was found in 32 cases. Associated lesions (fractures) were observed in 23 patients. One case of associated TCE was noted. Treatment was orthopedic in 18 patients, surgical in 18 patients and functional in 9 patients. According to the Matta criteria we obtained after treatment 46.7% good reduction, 51.1% satisfactory and 2.2% unsatisfactory reduction. According to the Postel-Merle D'Aubigné rating, 16 patients obtained excellent results with overall 93.3% satisfactory results. The complications found were coxarthrosis (15 cases), para-articular ossification (2 cases) and vicious callus (1 case).

Conclusions: The treatment of acetabulum fractures depends on the type of fracture, the age and activities of the patients. Orthopedic, surgical as well as functional treatment can give good acetabular reconstructions and functional results.

Published: December 2020

Background: Open fractures and traumatic wounds constitute a major health problem. Amongst the armamentarium of wound care products available, negative pressure wound therapy (NPWT) is a modality that has transformed wound care and has been recommended for treating all kinds of acute and chronic wounds.

Methods: This prospective randomised comparative study was conducted at a tertiary care hospital in Northeast India. 30 patients were included in this study over a period of 24 months commencing from January 2018. The patients consisted of two groups of 15 each, the first group comprised patients who underwent treatment using NPWT and the second group was treated using standard wound therapy (SWT). The endpoint taken was a granulated wound or a wound ready for split skin grafting (SSG).

Results: The mean wound size difference between the NPWT group and the SWT group on day nine was 13±7.17 mm and 4.53±0.99 mm, respectively. Likewise, on day nine, 11 (73.3%) patients in the group treated using NPWT had no positive bacterial cultures compared to 8(53.3%) patients on SWT. The estimated cost of materials for each NPWT dressing change was roughly INR₹ 3446 (US$ 45.57).

Conclusions: NPWT is not a magic bullet and will not replace the basic methods of wound treatment such as wound debridement, infection control and ensuring adequate blood supply. Nevertheless, NPWT remains an integral part of the current scenario in wound care management and is cost effective under the condition that it accelerates wound healing when compared to traditional treatment.
Thoraco-lumbar high grade spinal cord astrocytoma: first documented case in a tertiary medical center and review of literature
Authors: Marquez John Patrick R. , Mamba Niccolo S.
Published: December 2020

This presents the first documented case of high grade spinal cord astrocytoma in a pediatric patient treated at a tertiary medical center and gives a comprehensive review of literature on the most current modes of diagnosis, treatment, and prognosis. We report the case of a 7-year-old male with complaints of inability to ambulate and associated low back pain, which rapidly deteriorated to complete paraplegia. Magnetic resonance imaging (MRI) of his spine revealed an intradural intramedullary spinal cord lesion extending from T11 to L5 vertebra, with considerations of spinal astrocytoma and ependymoma. The patient underwent en bloc laminectomy on T9-L3, partial resection of the intramedullary cord tumor, and subsequent laminoplasty with mini plates and screws. Histopathologic studies showed spinal cord astrocytoma, World Health Organization (WHO) grade 3 (anaplastic type). The patient’s neurologic status did not improve after the surgery and was advised to undergo chemo-radiation therapy but was lost to follow up. Ten months post-operation, patient sought consult due to severe back pain, generalized body weakness, and difficulty of breathing and was then admitted. Patient’s condition worsened that eventually resulted to his demise.

Authors: Shantha kumar A. M. , Sahanand Santosh , V. Rajan David
Published: December 2020

Ganglion cyst of the knee joint can be intra articular or extra articular. Large intra articular ganglionic cystic formations arising from the infrapatellar fat pad are quite uncommon and only few are reported. Treatment option is surgery(open/arthroscopic) depending on the site and size of the cyst. We report a case of giant ganglion cyst arising from the infra patellar Hoffa's fat pad which presents anterior to the patellar tendon through a rent in the medial retinaculum with the posterior wall of the cyst being adherent to the para tenon of the patellar tendon, in a 58 year old male which presents anterior to the patellar tendon through a rent in the patellar retinaculum which was adherent to the para tenon of the patellar tendon and it was managed by open excision of the cyst.

Authors: Reang Santosh , Saha Pulak , Das Tapan K.
Published: December 2020

Patella fracture consists of approximately 1% of all skeletal fractures. However bilateral patella fracture is even rarer (2-3% of all patella fractures) and is seen mostly in either dash board injuries or in different pathological conditions. A 21 year old male presented with bilateral patella fracture, where right patella was fractured due to RTA and the left one got fractured due to a fall while he was being helped for an X-ray for the first one. Bilateral tension band wiring was done and patient was being regularly followed up with good range of movement recovery. But again he had a fall in bathroom 3 month post-operative and on right side suffered a re-fracture. Modified tension band wiring was done. Patient gained full range of movement on both sides and returned to his normal activities at 9 months post op of index surgery. A case of bilateral patella fracture where mechanism of fracture for each patella fracture are different is unheard of. A case of bilateral patella fracture with re-fracture has not been reported yet in literature so far we know/ searched. Here we report and discuss the challenges in management of such a case and protocol we followed.

Published: December 2020

The article presents the data of an original study on the improvement of orthopedic treatment of partial secondary adentia in patients with concomitant chronic pathology of the gastrointestinal tract by the method of removable plate prosthetics. For this purpose, a comparative analysis of three alternative to each other preparations of methyl acrylic polymer for the manufacture of bases of prostheses was made: 1) «GC», 2) «3M-Espe», 3) «Ftorax». A scientific assumption has been formulated that the choice of a specific polymer preparation (within the comparison base) will lead to a change in the number of complications developing during the operation of the prosthesis. In three independent groups of patients, using the compared preparations of methyl acrylic polymer, the relative number of complications was estimated. After the implementation of the study, it was found that the most positive results are shown by the polymer «GC», the least positive – by the polymer «Ftorax», the polymer «3M-Espe» occupies an «intermediate position». The results obtained have a high level of statistical significance, which makes it possible to recommend them for consideration for use in the practice of orthopedic dentistry.

Authors: Eslami G. , Peletto S. , Vakili M. , Kargar S.
Published: December 2020

Background: Sarcocystosis is one of the most distributed parasitic diseases over the world, caused by Sarcocystis spp. In this study, we assessed the effect of electron beam irradiation on the viability of Sarcocystis spp. in beef. 
Methods: Experimental beef groups were irradiated by four different electron beam doses of 1, 2, 3, and 4 kGy, at intervals of 0 and 24 h after irradiation, then the samples were transferred inside a sterile microtube containing RNAlater solution and stored at -20 °C till next steps. RNA extractions and cDNA synthesis were done using the related kit in order to detect the presence of the 18S ribosomal RNA region. Relative quantification was carried out using SYBR Green Real time Polymerase Chain Reaction. The statistical analysis was done using SPSS 16.0 by Tukey’s and Kruskal-Wallis tests.
Results: Irradiation at zero time was not effective on viability of Sarcocystis, but at 24 h, irradiation doses of 3 (p=0.003) and 4 kGy (p=0.008) caused a significant reduction in Sarcocystis viability. Irradiation doses of 1 and 2 kGy had no significant (p>0.05) effect on Sarcocystis viability reduction. Also, no significant differences (p>0.05) were observed between irradiation doses of 3 and 4 kGy.
Conclusion: Electron beam radiation at dose of 3 kGy was effective as the optimal dose for the elimination of Sarcocystis spp. in beef.

Published: December 2020

The article is devoted to the substantiation of the need to improve the family legislation of the Russian Federation due to the lack of legal norms that clearly regulate modern forms and problems of marriage and family practices, as well as due to the contradictions existing in Russian family law. Life dynamics, a variety of life realities, value transformations are not “covered” by the current legal field: many conflict and controversial situations of modern marriage and family relations remain outside the legal regulation. This fact indicates the lag of law from life itself.
Grounds and Subjects of Temporary Performance of Duties of the President of the Russian Federation
Authors:   Leading Specialist, Lawyer of the Administration of the Kargasok Rural Settlement of the Kargasok District of the Tomsk Region, Goleschikhin Vadim S.
Published: December 2020

The Constitution of the Russian Federation assigns to the President a leading role in the system of higher federal bodies of state power, which requires clear grounds and precise procedure for temporary exercise of presidential powers. The Constitution assigns the Chairman of the Government of the Russian Federation as the subject authorized to temporarily replace the President in all cases when he is unable to fulfill his duties. At the same time, the constitutional norms do not regulate the situation when the duties of the President cannot be performed either by himself or the Chairman of the Government. The article discusses the issues of subjects that in the above case are authorized to legitimately assume the temporary exercise of powers of the head of state, and concludes that it is necessary to improve the norms of the Constitution of the Russian Federation in terms of expanding the list of subjects for temporary exercise of duties of the President and introducing constitutional control over the transfer of presidential powers, and to improve the legislation norms and their implementation practice in terms of regulating the procedure for the temporary fulfillment of duties of the Chairman of the Government of the Russian Federation.

The paper reveals some of the powers of the head of the Russian state after the adoption of amendments to the Constitution. Possible legal challenges in the sphere of expanding the powers of the President of the Russian Federation are identified, which may lead to an imbalance in the system of functioning of the rule of law in the triad of branches of government. Some conclusions are proposed to improve the institution of the Presidency. The trends of systematic expansion of the powers of heads of state are defined. There is a tendency to weaken the Executive and judicial power.
Challenges and Tasks of the Legal Regulation of Electric Power and Capacity Trading in the Wholesale Market
Authors:   Postgraduate Student of the Department of Energy Law of the Kutafin Moscow State Law University (MSAL), Koropets Nadezhda V.
Published: December 2020

The legal regulation of trading in the wholesale electric power and capacity market is based on the Law on the Electric Power Industry and the Wholesale Electric Power and Capacity Market Regulations. The peculiarities of legal regulation established by the Federal Law “On Insolvency (Bankruptcy)” should also be considered. As of March 17, 2020, the List of Wholesale Market Actors Undergoing Bankruptcy Proceedings included 40 companies. Poor payment behavior in the wholesale electric power and capacity market is one of the main issues. Failure to pay does not only affect the settlement status in the market, but also leads directly to an unscrupulous market player being declared insolvent. In this case, the existing legal regulation does not guarantee protection against wholesale electric power and capacity market transactions being disputed unreasonably. It seems that the best way to prevent transactions from being disputed in bad faith is to amend the current revision of Article 61.4 of the Bankruptcy Law by adding provisions stating in which cases transactions required by the wholesale electric power and capacity market rules cannot be disputed.

Authors: Alhelou M. , Gavrilov A.I.
Published: December 2020

Synthesis of Active Disturbance Rejection Control (ADRC) has been discussed in this work. Two main approaches have been presented for the second-order ADRC: Linear ADRC and nonlinear ADRC. A design procedure for the three main components of ADRC: controller, estimator, and disturbance rejection scheme has been presented in each approach. Parameters of the linear approach are tuned using the desired closed loop system bandwidth. Parameters of the nonlinear approach are selected by categorizing them first into usual parameters and key parameters. After that, the key parameters are optimized using Genetic Algorithm (GA). The two approaches have been tested on a quarter-car system that deals with the passenger comfort problem. Simulation results show a good performance and a good compensation for external disturbances and dynamic uncertainties
On one Saddle Point Search Algorithm for Continuous Linear Games as Applied to Information Security Problems
Authors: Bykov A.Yu. , Krygin I.A. , Grishunin M.V. , Markova I.А.
Published: December 2020

The paper introduces a game formulation of the problem of two players: the defender determines the security levels of objects, and the attacker determines the objects for attack. Each of them distributes his resources between the objects. The assessment of a possible damage to the defender serves as an indicator of quality. The problem of a continuous zero-sum game under constraints on the resources of the players is formulated so that each player must solve his own linear programming problem with a fixed solution of the other player. The purpose of this research was to develop an algorithm for finding a saddle point. The algorithm is approximate and based on reducing a continuous problem to discrete or matrix games of high dimension, since the optimal solutions are located at the vertices or on the faces of the simplices which determine the sets of players' admissible solutions, and the number of vertices or faces of the simplices is finite. In the proposed algorithm, the optimization problems of the players are sequentially solved with the accumulated averaged solution of the other player, in fact, the ideas of the Brown --- Robinson method are used. An example of solving the problem is also given. The paper studies the dependences of the number of algorithm steps on the relative error of the quality indicator and on the dimension of the problem, i.e., the number of protected objects, for a given relative error. The initial data are generated using pseudo-random number generators

El objetivo del presente estudio fue seleccionar cepas bacterianas de la rizósfera del cultivo de frijol y determinar su potencial para el control de Sclerotium rolfsii bajo condiciones in vitro e in planta. Se recolectaron muestras de suelo en los municipios de Ahome, Guasave y Angostura, Sinaloa, México, durante el ciclo agrícola 2018-2019. Los aislados se evaluaron bajo condiciones in vitro y se seleccionaron los mejores para la evaluación in planta e identificación molecular (tres aislados) con base a la región 16S del ADN ribosomal. Se evaluaron 65 aislados bacterianos in vitro contra S. rolfsii con un porcentaje de inhibición de 2.5 a 65%. Acinetobacter pittii (COHUI06), Pseudomonas putida (SANMI02) y Burkholderia sp. (GLS06) inhibieron 55, 60 y 65% bajo condiciones in vitro; además resultaron no hemolíticas. Solo Burkholderia sp. ejerció mayor porcentaje de inhibición in planta para el control de S. rolfsii, con reducción de incidencia y severidad de la enfermedad en un 40 y 50% respectivamente, y promovió el peso seco de la planta. Para A. pitti o P. putida no fueron eficientes para el control del hongo in planta. Se sugiere hacer estudios con las bacterias en invernadero y campo.

El basidiomiceto Sporisorium reilianum f. sp. zeae infecta al cultivo de maíz y causa importantes pérdidas en regiones donde existen condiciones propicias para el desarrollo de la enfermedad. En este trabajo se evaluó la respuesta a la selección de seis ciclos de selección recurrente de maíces de endospermo blanco y cinco ciclos de maíces de endospermo amarillo para caracteres agronómicos deseables, rendimiento de grano y resistencia al carbón de la espiga. Los diferentes ciclos en las dos poblaciones se obtuvieron siguiendo el método de selección recurrente de familias S1, los cuales fueron evaluados para determinar el avance genético. En un ensayo anexo, las poblaciones fueron inoculadas artificialmente para medir el progreso de la resistencia a la enfermedad y evaluar un nuevo método de inoculación. Se utilizó un diseño experimental de bloques completos al azar con tres repeticiones para el ensayo de rendimiento y dos repeticiones para el ensayo inoculado. Los ciclos evaluados en las dos poblaciones mostraron un incremento en la resistencia de 0.94 y 1.2% ciclo-1, una ganancia genética para rendimiento de grano de 272.9 y 620 kg ha-1 ciclo-1 para la población blanca y amarilla, respectivamente. Los resultados mostraron que la selección recurrente de familias S1 fue eficiente para mejorar el rendimiento de grano y resistencia al carbón de la espiga en ambas poblaciones.
Phylogeny of ATP/ADP translocase gene from Candidatus Liberibacter spp., causal agents of HLB
Authors: Flores-de la Rosa Felipe Roberto , Rodríguez-Quibrera Cynthia Guadalupe , Santillán-Mendoza Ricardo
Published: December 2020

Las bacterias causantes del huanglongbing (HLB), Canditatus Liberibacter spp., son bacterias obligadas al floema de los cítricos y a diferentes sistemas del insecto vector, Diaphorina citri, por lo tanto, el enfoque genómico ha sido útil para estudiar sus mecanismos de patogenicidad. Dicho enfoque ha permitido identificar una copia homóloga del gen codificante de la enzima ATP/ADP translocasa, la cual tiene la capacidad de importar ATP y nucleótidos desde el hospedante, causando un parasitismo de energía considerable. Esta enzima se ha relacionado con la actividad endoparasítica de patógenos animales y humanos más que con fitopatógenos. El presente trabajo analizó la relación evolutiva entre la secuencia de aminoácidos de la ATP/ADP translocasa entre diferentes especies de Ca. Liberibacter y grupos como Ricketssia sp. y Chlamydia sp. Análisis filogenéticos muestran que la variación en la secuencia del gen codificante de la enzima está delimitada en clados correspondientes a las especies de Ca. Liberibacter, sugiriendo que la variación en la enzima responde a un proceso coevolutivo con los hospederos. Asimismo, la filogenia muestra que el ancestro común más cercano a Ca. Liberibacter podría ser un endosimbionte no patogénico del género Ca. Midichloria. Análisis de conservación de la secuencia de aminoácidos muestran que existen varias posiciones en la secuencia que podrían estar relacionadas con la variación específica de esta enzima dentro de Ca. Liberibacter. Este trabajo presenta la hipótesis de que el origen evolutivo de la capacidad de parasitismo energético del género Ca. Liberibacter, causantes del HLB, es un endosimbionte no patogénico.

Elements of Bi-cubic Polynomial Natural Spline Interpolation for Scattered Data: Boundary Conditions Meet Partition of Unity Technique
Authors: Xu Weizhi
Published: December 2020

This paper investigates one kind of interpolation for scattered data by bi-cubic polynomial natural spline, in which the integral of square of partial derivative of two orders to x and to y for the interpolating function is minimal (with natural boundary conditions). Firstly, bi-cubic polynomial natural spline interpolations with four kinds of boundary conditions are studied. By the spline function methods of Hilbert space, their solutions are constructed as the sum of bi-linear polynomials and piecewise bi-cubic polynomials. Some properties of the solutions are also studied. In fact, bi-cubic natural spline interpolation on a rectangular domain is a generalization of the cubic natural spline interpolation on an interval. Secondly, based on bi-cubic polynomial natural spline interpolations of four kinds of boundary conditions, and using partition of unity technique, a Partition of Unity Interpolation Element Method (PUIEM) for fitting scattered data is proposed. Numerical experiments show that the PUIEM is adaptive and outperforms state-of-the-art competitions, such as the thin plate spline interpolation and the bi-cubic polynomial natural spline interpolations for scattered data.

SYNCHRONOUS COLORECTAL CANCERS: SINGLE CENTER EXPERIENCE

INTRODUCTION:

Synchrous colorectal cancers forms %1,1-8,1of all colorectal cancers (CRC) and preoperatif diagnosis of them effects directly surgical procedure and prognosis.We present our clinical experience about synchronous CRC patients with their clinicopathologic charasteritics, treatment options and survival rates.

METHODS:

Since January 2009 till December 2018, 17 synchronous CRC diagnosed patients’ hospital records were evaluated retrospectively. Localization and histopathology of tumor, surgery procedures and survival rates were concluded.

RESULTS:

Synchronous colon tumors were detected in 17 (2.2%) out of 757 CRC patients operated in our clinic, 14 of them were male (82.3%) and 3 were female (17.7%). Two synchronous tumors were detected in 16 patients and three synchronous tumors in one patient. Two patients (11.7%) underwent multiple colon resection, 7 patients (41.1%) underwent segmental colon resection, and 8 patients (47.1%) underwent extensive colon resection. Two of the patients who were followed-up were exitus.

CONCLUSION:

Preoperative evaluation of synchronous colon tumor is very important, because presence will change directly the surgical technique and the prognosis of the patient, so all CRC patients should undergo complete preoperative evaluation.
Children's memory of a story experienced with virtual reality versus traditional media technology
Authors: Araiza Paola , Keane Therese , Chen Won Sun , Kaufman Jordy
Published: December 2020

Immersive Virtual Reality Technology (IVR) is a visual multi-sensory computer-simulated environment that perceptually surrounds an individual, creating the illusion that one has “stepped inside” and is included in, and interacting with the generated world. Although IVR has been suggested as a tool to enhance learning, existing work has not examined how IVR presentations, compared with other types of storytelling, facilitate or interfere with children’s memory formation. Here, we present data from a study of seventy 6- and 7-year-old children randomly assigned to experience a story in one of three modalities: IVR, video, or a paper-based book. We assessed the children’s story recall and their ability to identify the protagonist’s emotions. Results showed that, overall, children in the IVR condition performed better in the memory-recall task than the children in the video and book conditions. The most pronounced difference in memory performance was between the IVR and book conditions. In the IVR versus video conditions, 6-year-olds performed significantly better in the IVR condition than in the video condition, while 7-year-olds performed similarly in both digital-story conditions. We found no effects of condition on children’s attribution of emotions to the story’s protagonist. We conclude that IVR may enhance children’s ability to learn story content in certain situations.

Distributional word vector representation orword embedding has become an essential ingredient in many natural language processing (NLP) tasks such as machine translation, document classification, information retrieval andquestion answering. Investigation of embedding model helps to reduce the feature space and improves textual semantic as well as syntactic relations.This paper presents three embedding techniques (such as Word2Vec, GloVe, and FastText) with different hyperparameters implemented on a Bengali corpusconsists of180 million words. The performance of the embedding techniques is evaluated with extrinsic and intrinsic ways. Extrinsic performance evaluated by text classification, which achieved a maximum of 96.48% accuracy. Intrinsic performance evaluatedby word similarity (e.g., semantic, syntactic and relatedness) and analogy tasks. The maximum Pearson (ˆr) correlation accuracy of 60.66% (Ssˆr) achieved for semantic similarities and 71.64% (Syˆr) for syntactic similarities whereas the relatedness obtained 79.80% (Rsˆr). The semantic word analogy tasks achieved 44.00% of accuracy while syntactic word analogy tasks obtained 36.00%
The Arithmetic of Uncertainty unifies Quantum Formalism and Relativistic Spacetime
Authors: Skilling John , Knuth Kevin
Published: December 2020

The theories of quantum mechanics and relativity dramatically altered our understanding of the universe ushering in the era of modern physics. Quantum theory deals with objects probabilistically at small scales, whereas relativity deals classically with motion in space and time. We show here that the mathematical structures of quantum theory and of relativity follow together from pure thought, defined and uniquely constrained by the same elementary ``combining and sequencing'' symmetries that underlie standard arithmetic and probability. The key is uncertainty, which inevitably accompanies observation of quantity and imposes the use of pairs of numbers. The symmetries then lead directly to the use of complex \sqrt{-1} arithmetic, the standard calculus of quantum mechanics, and the Lorentz transformations of relativistic spacetime. One dimension of time and three dimensions of space are thus derived as the profound and inevitable framework of physics.

Livestock production systems generate nuisance odor and gaseous emissions affecting local communities and regional air quality. Also, there are concerns about the occupational health and safety of farm workers. Proven mitigation technologies that are consistent with the socio-economic challenges of animal farming are needed. We have been scaling up the photocatalytic treatment of emissions from lab-scale, aiming at farm-scale readiness. In this paper, we present the design, testing, and commissioning of a mobile laboratory for on-farm research and demonstration of performance in real farm conditions. The mobile lab is capable of treating up to 1.2 m3·s-1 of air with TiO2-based photocatalysis and adjustable UV-A dose based on LED lamps. We summarize the main technical requirements, constraints, approach, and performance metrics for the mobile laboratory, such as the effectiveness (measured as the percent reduction) and cost of photocatalytic treatment of air. The commissioning of all systems with standard gases resulted in ~9% and 34% reduction of NH3 and butan-1-ol, respectively. We demonstrated that as the percent reduction of standard gases increased with increased light intensity and treatment time. These results show that the mobile laboratory was ready for on-farm deployment and evaluating the effectiveness of UV treatment.

In pediatric practice, much attention is paid to natural components used for the prevention and treatment of respiratory infections. Nasal drops Tamba Tuya (Adonis LLC, Russia) contain extracts of peloid from lake Tambukan, thuja, essential oils of fir, lavender, vitamin E, dexpanthenol, dihydroquercetin, glycerol, olive oil, and peach oil. These components are effective for the prevention and treatment of rhinitis, adenoiditis, bacterial complications, as well as for prevention of adverse reactions from decongestants. We have developed a method of its application that has not only local, but also systemic effects in children. Step 1: nasal rinsing with saline solutions; step 2: instilling Tamba Tuya drops (1–2 drops in each nostril) three times a day; step 3: infriction of the drops into the skin on the temples for 2–3 minutes as aromatherapy, which ensures penetration of the drug components through the skin into the blood with a systemic effect. Minimum course duration: 2 weeks. The use of the drops from the first days of respiratory infections in 30 children aged 4 to 7 years in the experimental group (30 children were in the control group) ensured milder (76.3% compared to 60% in the control group) and shorter disease (by 2 days). The majority of participants (83.3%) from the experimental group demonstrated rapid resolution of rhinitis symptoms and lower need for decongestants. A total of 86.6% of children in the experimental group and 53.3% of controls showed an improvement in emotional and behavioral responses, including activity, adaptability, intensity, mood, and distraction.

Objective. To evaluate the frequency, nature, and structure of therapy for uveitis associated with juvenile idiopathic arthritis (JIA) using the data from the Moscow city register of children with rheumatic diseases. Patients and methods. We analyzed the data of 117 patients with JIA and uveitis aged between 3 and 17 years residing in Moscow. Results. JIA-associated uveitis was diagnosed in 11% of children with JIA. It was more common in females than in males (13.1% vs 7.3% respectively). More than half of patients with uveitis (53.8%) had oligoarticular JIA, whereas 34.2% of patients had polyarticular RF-seronegative JIA. The majority of children (85.5%) received basic therapy, primarily with methotrexate (97% of them). Biologicals were administered to 64.1% of patients; of them, 68% received adalimumab. Sixty-one percent of children had bilateral eye lesions. In 41.5% of patients, the disease started with joint syndrome, while 46.3% of patients had both joint syndrome and eye lesions at onset and 12.2% of children initially had eye lesions. Remission of uveitis was registered in 75.6% of patients. Conclusion. Our results are consistent with both Russian and foreign data. Early diagnosis of uveitis and its timely treatment will decrease the incidence of complications in patients with JIA (including complete vision loss) and reduce the burden of disability for patients, their families, and the state. Key words: biological therapy, rheumatoid uveitis, rheumatic diseases in children, juvenile arthritis

Public health-related misinformation spread rapidly in online networks, particularly, in social media during any disease outbreak. Misinformation of coronavirus disease 2019 (COVID-19) drug protocol or presentation of its treatment from untrusted sources have shown dramatic consequences on public health. Authorities are utilizing several surveillance tools to detect, and slow down the rapid misinformation spread online, still millions of misinformation are found online. However, there is no currently available tool for receiving real-time misinformation notification during online health or COVID-19 related inquiries. Our proposed novel combinational approach, where we have integrated machine learning techniques with novel search engine misinformation notifier extension (SEMiNExt), helps to understand which news or information is from unreliable sources in real-time. The extension filters the search results and shows notification beforehand; it is a new and unexplored approach to prevent the spread of misinformation. To validate the user query, SEMiNExt transfers the data to a machine learning algorithm or classifier which predicts the authenticity of the search inquiry and sends a binary decision as either true or false. The results show that the supervised learning algorithm works best when 80% of the data set have been used for training purpose. Also, 10-fold cross-validation demonstrate a maximum accuracy and F1-score of 84.3% and 84.1% respectively for the Decision Tree classifier while the K-nearest-neighbor (KNN) algorithm shows the least performance. The SEMiNExt approach has introduced the possibility to improve online health communication system by showing misinformation notifications in real-time which enables safer web-based searching while inquiring on health-related issues.
