Multisystem Inflammatory Syndrome in Children Associated with COVID-19 Infection: A Comprehensive Review
Authors: Meza-Contreras Alejandra Isabel , Galdos-Bejar Marcelo Nicolas , Escalante-Kanashiro Raffo 
Published: June 2022

AbstractThe Multisystem Inflammatory Syndrome in Children (MIS-C) is a postinfectious syndrome associated with coronavirus disease 2019 (COVID-19) disease in children. The aim of this study is to conduct a thorough review to assist health care professionals in diagnosis and management of this complication of COVID-19 disease in children. A thorough systematic review was conducted through an on-line search based on MIS-C with the primary focus on epidemiology, clinical characteristics, diagnosis, pathophysiology, management, and long-term follow-up. This syndrome is characterized by an exaggerated and uncontrolled release of proinflammatory cytokines involving dysfunction of both innate and adaptive immunity. In this review, a summary of observational studies and case reports was conducted, in which we found that MIS-C generates multiple-organ failure frequently presenting with hemodynamic instability further characterized by Kawasaki-like symptoms (such as persistent high fever, polymorphic rash, and bilateral conjunctivitis) and predominance of gastrointestinal and cardiovascular signs and symptoms. Keys to effective management involve early diagnosis, timely treatment and re-evaluation following hospital discharge. Diagnosis is marked by significant elevation of inflammatory biomarkers, laboratory evidence of COVID-19 infection or history of recent exposure, and absence of any other plausible explanation for the associated signs, symptoms, and presentation. Management includes hemodynamic stabilization, empiric antibiotic therapy (de-escalation if cultures and polymerase chain reaction studies indicate no bacterial co-infection), immunomodulatory therapy (methylprednisolone, intravenous immunoglobulin, anakinra, tocilizumab, siltuximab, Janus kinase inhibitors, tumor necrosis factor-α inhibitors), antivirals (remdesivir), and anticoagulation (acetylsalicylic acid, unfractionated or low-molecular-weight heparin or new oral anticoagulants). In addition, we identified poor prognostic risk factors to include concurrent comorbidities, blood-component consumption and marrow suppression (lymphopenia, thrombocytopenia), depletion of homeostatic components (hypoalbuminemia), and marked evidence of a hyperinflammatory response to include elevated values of ferritin, C-reactive protein, and D-dimer. MIS-C constitutes a postinfectious syndrome characterized by a marked cytokine storm, characterized by fever, bilateral conjunctivitis, and multiple organ dysfunction. Promoting future research and long-term follow-up will be essential for the development of guidelines and recommendations leading to effective identification and management of MIS-C.

Abstract
Objective To evaluate the acceptance of telemedicine and determine its associated factors in an urogynecology outpatient clinic of a public hospital in Brazil.
Methods The present was a cross-sectional study performed between June and November 2020. The included patients had their elective appointments postponed due to the coronavirus disease 2019 (COVID-19) pandemic. The variables considered regarding the acceptance of telemedicine were: urogynecologic diagnosis, age, level of schooling, place of residence, access to the internet, type of device used, frequency of internet use, and use of social media platforms. The categorical variables were described by their absolute and relative frequencies. The association among variables was evaluated through the Fisher exact test, and univariate and multivariate analyses, considering the acceptance of telemedicine as the dependent variable.
Results A total of 225 patients were listed, and 182 agreed to participate. The mean age was 59 years old, 81.3% of the patients had access to the internet, and 87.3% of them accepted telemedicine. There were statistically significant associations regarding the acceptance of telemedicine and high levels of schooling (p < 0.01), internet access (p < 0.01), daily use of the internet (p < 0.01), access through personal mobile phone (p < 0.01), and access through the participant's own residence (p < 0.01). In the univariate and multivariate analyses, only high levels of schooling were associated with the acceptance of telemedicine (Adjusted odds ratio: 4.82; 95% confidence interval = 1.59–14.65).
Conclusion Most of the urogynecology patients of a public hospital in a developing country accepted telemedicine. Internet access and level of schooling were the factors associated with the acceptance of telemedicine in urogynecology.
Mechanical Ventilation during ECMO: Lessons from Clinical Trials and Future Prospects
Authors: Fior Gabriele , Colon Zasha F. Vazquez , Peek Giles J. , Fraser John F. 
Published: June 2022

AbstractAcute Respiratory Distress Syndrome (ARDS) accounts for 10% of ICU admissions and affects 3 million patients each year. Despite decades of research, it is still associated with one of the highest mortality rates in the critically ill. Advances in supportive care, innovations in technologies and insights from recent clinical trials have contributed to improved outcomes and a renewed interest in the scope and use of Extracorporeal life support (ECLS) as a treatment for severe ARDS, including high flow veno-venous Extracorporeal Membrane Oxygenation (VV-ECMO) and low flow Extracorporeal Carbon Dioxide Removal (ECCO2R). The rationale being that extracorporeal gas exchange allows the use of lung protective ventilator settings, thereby minimizing ventilator-induced lung injury (VILI). Ventilation strategies are adapted to the patient's condition during the different stages of ECMO support. Several areas in the management of mechanical ventilation in patients on ECMO, such as the best ventilator mode, extubation-decannulation sequence and tracheostomy timing, are tailored to the patients' recovery. Reduction in sedation allowing mobilization, nutrition and early rehabilitation are subsequent therapeutic goals after lung rest has been achieved.

Published: June 2022

AbstractThis study aimed to study the practice and effect of monitoring hospitalized pediatric patients in terms the length of stay (LOS). We have performed a prospective, observational study of pediatric patients in the general ward from October to December 2016. We have recorded the use of cardiac monitor, pulse oximeter, or both, and as per physician order at patient admission. We have studied the proportions of monitoring in different patient groups. We have applied a linear regression model to investigate the relationship between LOS and cardiopulmonary monitoring, orders, and medical complexity. Among 399 patients, patients with cardiac and pulse oximeter monitoring with orders were 68 and 82%, respectively. The pulmonary group had more monitoring than the neurology group of patients. LOS was shorter in patients without monitoring; the median difference for the cardiac monitoring was one day (interquartile range [IQR] = 1), and the pulse oximeter was 0.5 days (IQR = 1). Cardiac monitoring order increased LOS by 22% (95% confidence interval [CI]: 0.5, 48%) and complex past medical history increased it by 25% (95% CI: 4, 51%). Our study highlights the variable practice in using monitors, emphasizing a standardized approach. The judicious use of monitoring may reduce prolonged hospitalization. Selective use of physiologic monitoring of ill-appearing or at risk of hypoxemia or cardiac dysrhythmia will reduce overuse.
Predicting the Position of the Internal Landmarks of Middle Cranial Fossa Using the Zygomatic Root: An Attempt to Simplify Its Complexity

Published: June 2022

AbstractSubtemporal–extradural middle cranial fossa (MCF) surgical approach is used to access pathologies involving anterior or posterior part of the petrous bone or its apex. A reliable and precise identification of the important internal landmarks is key to a safe surgery with decreased incidence of morbidity. The zygomatic root (ZR) serves as a reliable reference guide for the surgeon when navigating through the MCF. The aim of the study is to establish an association between the extent of the ZR to the key internal foramina and bony prominences in lateral fossa of the MCF to help the neurosurgeon to safely navigate through the maze of structures of the MCF. The study demonstrates that the ZR is a reliable marker to estimate and predict the position of foramen ovale, foramen spinosum, and trigeminal fossa but not for the position of hiatus of greater petrosal nerve or the arcuate eminence. Successful localization of the foramen ovale, spinosum, and trigeminal fossa would reduce intraoperative time, ensure lesser retraction of brain, and hence reduce patient morbidity while performing surgeries on lesions of/in the internal acoustic canal, petroclival junctions, cerebellopontine angles, basilar artery, or transovale cannulation for the treatment of trigeminal neuralgia.
Differential object marking in heritage and homeland Italian
Authors: di Salvo Margherita , Nagy Naomi 
Published: June 2022

Abstract
We examine variable patterns of use of differential object marking (DOM) in conversational Italian recorded in
Toronto, Canada, and Calabria, Italy. An exhaustive sample of 366 direct objects, produced by Homeland and three generations
of Heritage speakers, shows retention of the DOM system. Successive generations have lower rates of DOM, but this is because
they don’t produce enough tokens of certain syntactic and semantic types (e.g., left-dislocated or indefinite pronouns). Thus,
they have less opportunity to use DOM: token distributions account for their lower rates. In contexts with sufficient tokens,
significant contrasts emerge, indicating that all generations retain the conditioning of relevant factors (Definiteness,
Referent of Object, Verb Type, Dislocation). No effects of social network or linguistic practices emerged.
On (not) acquiring a sociolinguistic stereotype
Authors: Davidson Justin 
Published: June 2022

Abstract
Catalan exhibits a systematic velarization of alveolar lateral /l/ to (dark) [ɫ], somewhat infamously and even
pejoratively recognized by speakers as la ela catalana ‘the Catalan l,’ in salient opposition to the
non-velarized (or light) realizations of the parallel alveolar lateral Spanish category, realized as [l] (Bibiloni 2006; Davidson 2019; Hualde 2005). In light of an attested negative social stigma afforded to velarized /l/
(Davidson 2019; Pieras 1999; Simonet 2010a), in this study I examine the variable acquisition of Catalan /l/ by
L1-Spanish speakers. In so doing, I problematize the assessment of successful second language acquisition for an L1
sociolinguistic stereotype (cf. Labov 2001), ultimately demonstrating how
L2-speakers adopt native-like sociolinguistic variation with non-native-like speech variants.

AbstractLithium-ion batteries have achieved huge success in the field of energy storage, but they use flammable electrolytes that may cause safety issue. Solid polymer electrolytes have been considered as the final solution to this safety issue, which have received many researchers’ attention. However, solid polymer electrolytes still face several challenges, such as low ionic conductivity. Herein, we report a quaternary solid polymer electrolyte to achieve high ionic conductivity, which was synthesized by one-step casting method. This quaternary electrolyte contains two polymers (poly(vinylidene fluoride-co-hexafluoropropylene) and poly(ethylene oxide) diacrylate), one plasticizer (succinonitrile), and one lithium salt (lithium bis(trifluoromethane)sulfonimide). Long-chain polymer is used as matrix, and short-chain polymer and plasticizer are used to increase ionic conductivity. This quaternary electrolyte achieves a high ionic conductivity of 1.49 × 10−4S cm−1at room temperature. When assembled into coin cell with lithium iron phosphate cathode and lithium metal anode, this quaternary electrolyte achieves a capacity of 139 mAh g−1at 0.2 C after 50 cycles and 106 mAh g−1at 1 C after 160 cycles. Moreover, this facile one-step casting method provides a new route towards the development of solid polymer electrolytes.
Investigation into cage slip and vibration behavior of rolling bearing based on weak magnetic detection
Authors: Zhan Liwei , Li ZhengHui , Chi Jie , Zhuo Shi , Li Chengwei 
Published: June 2022

Abstract
Cage slip and vibration are two key indicators for evaluating bearing health status. However, in actual service, due to the limitations of installation space and interference from harsh environments such as high temperatures and oil mist, it is difficult to detect the cage slip and vibration of rolling bearings. To solve this problem, based on the principle of bearing motion under magnetic field disturbance, a weak magnetic detection method is proposed to obtain mixed feature information about cage motion and bearing vibration. To separate the kinematic characteristics of the bearings, a method of local reconstruction based on intrinsic mode functions and a comprehensive evaluation index based on statistical parameters is proposed to identify the relevant mode including cage motion and vibration behavior. The cage slip and vibration characteristics are obtained by the fast Fourier transform and envelope demodulation technique. The different fault levels of rolling bearings are used to evaluate the performance of the proposed method under variable speed. The results show that the proposed method can identify cage slip and vibration behavior effectively.
Rapid detection method of radioactive source based on low-count gamma spectra
Authors: Yuan Y. , Qu J. , He J. , Tan Z. , Liu Y. 
Published: June 2022

Abstract
This paper presented a mobile CsI gamma detector developed
to solve the problem of radioactive source detection in a wide
area. The performance of the detector was illustrated during the
spectra collection investigation. 1-s spectrum collected by the
detector was low-count signal, which is hard to distinguish whether
it is a source contained signal or not. A rapid detection method of
radioactive source based on the low-count gamma spectra was
proposed. Principal component analysis (PCA) was the key technology
which was able to extract the source information efficiently. The
proposed method improved the detector sensitivity and accuracy.
Trajectories of charged particles in knotted electromagnetic fields
Authors: Kumar Kaushlendra , Lechtenfeld Olaf , Costa Gabriel Picanço 
Published: June 2022

Abstract
We investigate the trajectories of point charges in the background of finite-action vacuum solutions of Maxwell’s equations known as knot solutions. More specifically, we work with a basis of electromagnetic knots generated by the so-called ‘de Sitter method’. We find a variety of behaviors depending on the field configuration and the parameter set used. This includes an acceleration of particles by the electromagnetic field from rest to ultrarelativistic speeds, a quick convergence of their trajectories into a few narrow cones asymptotically for sufficiently high value of the coupling, and a pronounced twisting and turning of trajectories in a coherent fashion. This work is part of an effort to improve the understanding of knotted electromagnetic fields and the trajectories of charged particles they generate, and may be relevant for experimental applications.
Optimization of agricultural land use by impact on the climate
Authors: Kiryushin V I 
Published: June 2022

Abstract
An assessment of the agrogenic transformation of the main ecological landscape functions affecting the greenhouse effect (bioproductive, destructive, organo-accumulative, biogeochemical) is given. It is shown that the tasks of optimizing agricultural environmental management under economic and agroecological conditions coincide with the tasks of maintaining a deficit-free carbon balance, reducing nitrogen gas losses and greenhouse gas emissions. The inexpediency of using emergency alarmist measures to reduce greenhouse gases is justified. The immediate tasks of optimizing nature management are associated with the development of adaptive landscape farming systems and ecological optimization of animal husbandry, which will ensure a deficit-free balance of carbon and biogenic elements, significantly stop the processes of soil and landscape degradation, and significantly reduce CO2 emissions.
Prospects for the development of adaptive landscape farming systems in Russia
Authors: Kiryushin V I 
Published: June 2022

Abstract
The achievements of adaptive landscape agriculture systems (ALAS) were considered as an expression of a new, biospheric paradigm of nature management. ALAS are confined to various agroecological land groups (upland, erosive, hydromorphic, saline, etc.). Within the groups, there are land types for which agricultural technologies of various intensification levels are being developed. The ALAS design tools include a register of land types, a register of crop varieties, and a register of agrotechnologies. The development of ALAS projects for agricultural enterprises is carried out in AgroGIS based on soil and landscape mapping materials based on agroecological typology and landscape-ecological classification of lands. ALAS are formed based on the results of multifactorial field experiments that establish systemic links between agriculture elements and landscape-ecological conditions. The ALAS development is associated with the deepening of landscape differentiation and further with the design of agricultural landscapes (cultivated lands, livestock, water, forestry, residential ones) in the territory ecological framework system. The methodology and tools of their design based on the transformation of ecological functions of the landscape into socio-economic ones are proposed.

Published: June 2022

Abstract
The presented research is the first to study the fodder productivity, nutritive and energy value of new varieties of Festulolium of different morphotypes in the conditions of the forest-steppe of the Central Chernozem Region of Russia. In the green mass of the studied varieties crude protein content was quite low ranging from 6.2 to 9.7%, which was 1.4-2.3 times lower than required by zootechnical norms for cattle feeding. The studied varieties of Festulolium were distinguished by a rather high content of soluble sugars, which was 14.7-19.4%. The Viknel variety contained more digestible protein (68.74-76.01 g), but this value did not differ much from other varieties, in which it ranged from 64.78 to 72.47 g/kg of green mass. Among the studied varieties of Festulolium the highest yield of green mass was obtained in the second and third years of grass stand life. Productivity of the Izumrudnyi fescue-type mowing variety reached 40.31-44.09 t/ha, which was 1.3-1.9 times higher than that of ryegrass-type mowing-and-grazing varieties, the yield of which was 23.07-31.24 t/ha.

A Contribution to the Study of Pollination of Alfalfa Medicago Sativa (L.) by Bees Osmia Cornuta (latreille, 1805) (HYMENOPTERA: MEGACHILIDAE) in the Donbass Region
Authors: Kuzicheva Nadezhda N 
Published: June 2022

Abstract

O. cornuta is a monovaltine polylectic bee, which in natural conditions prefers to forage, visiting fruit and berry crops, or, if they are missing, other plant species. With the aim of defining whether a bee under study is able to mate and build a nest in the summertime, detecting temperature conditions of the first emergence of individuals and specifying the duration of a lifecycle of breeding stock during the period of active flight, we conducted an experiment on the field of alfalfa Medicago sativa (Linnaeus, 1753) in agricultural limited liability company “Timiryazevskoe” in Amvrosievskiy raion, in the summertime (the third decade of June – the first decade of July). The data were obtained after artificially prolonged cold diapause of cocoons. For prolongation of diapause, refined cocoons of imagoes were placed in the fridge. After removal of cocoons from the fridge, incubated breeding stock was transported to the experimentation area and placed in previously prepared artificial nesting constructions. For nesting of future offspring bundles of single-channel reed were used. When nesting constructions had been installed, we started to observe emergence of male imagoes, followed by emergence of female imagoes. The article provides information about seasonal and circadian activity, lifecycle of bees O.cornuta. The received data could be used to plan artificial breeding of O.cornuta with a view to pollination of entomophilous agricultural plants on open ground during the summer period.

Abstract
The article provides a basis for the need to reform the agricultural sector of Uzbekistan in general, and its fruit and vegetable industry in particular. The main problems faced by the agricultural sector of Uzbekistan were the high costs of collection, transportation, storage, processing, packaging and certification when delivering products from the field to end-users. Limited processing and packaging capacity of farms, which produce the bulk of fruit and vegetable exports in Uzbekistan, leads to significant losses. It should be noted that the share of agro-clusters in the markets of developed countries (European Union, USA and Canada) exceeds 40%, and in Uzbekistan this direction is only developing. In this regard, the article used the following tasks: to study the theoretical basis for the creation of agro-clusters to analyze the current economic situation in the country, to make recommendations for the creation of agro-clusters in fruit and vegetable products.
