Published: March 2023

Metal-organic polyhedra (MOPs) are discrete molecules made of metal ions/clusters and organic ligands, and their crystal packing leads to the generation of intrinsic and extrinsic porosity. Due to their structural versatility, porosity, and nanoscale size, MOPs are considered an attractive platform for catalysis. In this study, we report for the first time the use of three zirconium(IV)-based MOPs for the degradation of trace concentrations of the nerve agent simulant, dimethyl 4-nitrophenyl phosphate (DMNP). All three MOPs degraded DMNP instantaneously, with half-lives ranging from t1/2 = 17 to 130 s. The catalytic activity of MOPs is thought to be due to (1) their periodic packing resulting in long-range order that creates extrinsic porosity, allowing DMNP to diffuse in and interact with the pore surface and Lewis acids (Zr(IV) centers) of MOPs, and (2) the lability of Zr-Cp (Cp = cyclopentadienyl) bond, allowing Cp ligands to rearrange and make space for DMNP to interact with the Zr(IV). The catalytic activity of MOPs is not deteriorated by increasing the concentration of the nerve agent simulant nor in consecutive catalytic experiments, highlighting their robustness as catalysts. Our study showcases the promise of MOPs as one of the fastest active catalysts for the instantaneous degradation of nerve agents.

Authors: Hirschmann Oliver , Bhakta Harsh H. , Xiong Wei
Published: March 2023

Vibrational polaritons have shown to modify chemical reactions, and thus, understanding its vibrational energy dynamics is a key to rationally design polariton chemistry. In this work, using tailored two-dimensional infrared pump probe spectroscopy and a modified transfer matrix model, we showed that the Raman-active Eg mode plays role in energy relaxation process of W(CO)6 polariton system. Precisely, after LP excitation, instead of relaxing to the 1st and 2nd excited state of T1u dark modes, a certain population of LP scatters through a phonon-assisted process to the Eg mode, which later decays into the population of T1u states. The involvement of the Eg mode, which was not considered in previous polariton studies, indicates the importance of considering non-IR active modes in polariton chemistry and dynamics. Furthermore, the current study indicate a viable pathway that polariton influence chemistry, by open up vibrational dynamic channels that are inaccessible under regular conditions.
Characterizing Surface Ice-philicity Using Molecular Simulations and Enhanced Sampling
Authors: Marks Sean , Vicars Zachariah , Thosar Aniket , Patel Amish
Published: March 2023

The formation of ice, which plays an important role in diverse contexts, ranging from cryopreservation to atmospheric science, is often mediated by solid surfaces. Although surfaces that interact favorably with ice (relative to liquid water) can facilitate ice formation by lowering nucleation barriers, the molecular characteristics that confer a surface with "ice-philicity" are complex and incompletely understood. To address this challenge, here we introduce a robust and computationally effcient method for characterizing surface ice-philicity, which combines molecular simulations and enhanced sampling techniques to quantify the free energetic cost of increasing surface-ice contact at the expense of surface-water contact. Using this method to characterize the ice-philicity of a family of model surfaces that are latticed matched with ice but vary in their polarity, we find that the non-polar surfaces are moderately ice-phobic, whereas the polar surfaces are highly ice-philic. In contrast, for surfaces that display no complementarity to the ice lattice, we find that ice-philicity is independent of surface polarity and that both non-polar and polar surfaces are moderately ice-phobic. Our work thus provides a prescription for quantitatively characterizing surface ice-philicity and sheds light on how ice-philicity is infuenced by lattice matching and polarity.

Published: March 2023

Herein, we report the use of an ultramicroporous (pore size <0.7 nm) metal-organic framework (MOF), [Ni3(pzdc)2(ade)2(H2O)4]2.18H2O (H3pzdc: pyrazole-3,5-dicarboxylic acid, ade: adenine), for hydrogen (H2) adsorption. Upon activation, [Ni3(pzdc)2(ade)2] was generated, and in situ carbon monoxide loading transmission infrared spectroscopy revealed that open Ni(II) sites could be generated. The MOF displayed a Brunauer-Emmett-Teller (BET) surface area of 160 m2/g. Hydrogen adsorption collected on this MOF at 77 K revealed a steep uptake at low pressure, and H2 uptake saturation was achieved at 0.15 bar. The affinity of this MOF for H2 is 9.7 1.0 kJ/mol. An interplay of in situ H2 loading experiments and computations confirmed that H2 does not bind to the open Ni(II) sites of the MOF, and the observed high affinity of the MOF for H2 is mainly attributed to its narrow pore size. To shed light on the impact of ultramicropores on H2 uptake, we experimentally compared the H2 uptake per surface area unit as a function of the pore size of other ultramicroporous, microporous, and mesoporous MOFs. Our results showcase that ultramicropores contribute the most to H2 uptake, and the size, shape, and functionality of our MOF are ideal and can be used as guiding principles for the design and synthesis of novel adsorbents for efficient H2 storage and delivery.
Multifidelity neural network formulations for prediction of reactive molecular potential energy surfaces
Authors: Yang Yoona , Eldred Michael S. , Zádor Judit , Najm Habib N.
Published: March 2023

This paper focuses on the development of multifidelity modeling approaches using neural network surrogates, where training data arising from multiple model forms and resolutions are integrated to predict high-fidelity response quantities of interest at lower cost. We focus on the context of quantum chemistry and the integration of information from multiple levels of theory. Important foundations include the use of symmetry function-based atomic energy vector constructions as feature vectors for representing structures across families of molecules, and single-fidelity neural network training capabilities that learn the relationships needed to map feature vectors to potential energy predictions. These foundations are embedded within several multifidelity topologies that decompose the high-fidelity mapping into model-based components, including sequential formulations that admit a general nonlinear mapping across fidelities and discrepancy-based formulations that presume an additive decomposition. Methodologies are first explored and demonstrated on a pair of simple analytical test problems, and then deployed for potential energy prediction for C5H5 using B2PLYPD3 6-311++G(d,p) for high fidelity simulation data and Hartree Fock 6-31G for low fidelity data. For the common case of limited access to high-fidelity data, our computational results demonstrate that multifidelity neural network potential energy surface constructions achieve roughly an order of magnitude improvement, either in terms of test error reduction for equivalent total simulation cost or reduction in total cost for equivalent error.

Published: March 2023

Faradays legendary Molecules of Gold have stimulated intense interest (over 165 years) but have only recently begun to yield their secrets to modern methods of chemical analysis. Here(in), we demonstrate how striking charging patterns emerge directly from native electrospray of large, gold-rich molecules that were generated by reduction of various (8) small gold(I)thiolate complexes [-RS-Au(I)-SR-], followed by extensive thermochemical processing to enrich the most robust forms. In each case (R), electrospray ionization of a picomolar solution yields a characteristic series of abundant, highly resolved peaks at related (m/z)-ratios, that can be used to deduce charges {z e+} and hence a distinct molecular mass, {MR}. A plot of {MR} versus thiolate-mass {mL} yields a straight line with slope 60.0 (the ligand count) and an intercept of 28,364-Da, the mass of 144 Au-atoms. i.e., a unique molecular composition {197Au144(SR)60}. This formula agrees with the unique chiral-icosahedral structure-model, c@12@42@60@(30,60), the Pd145(CO)60-structure, that features a massively-compact globular Au114-core (~1.6-nm) and an intrinsically chiral (I) outer shell (~2.0-nm) with 12 distinct ligand types of 5-fold equivalence], denoted by Martin et al. as virus-like on the basis of its resemblance of icosahedral-virus capsids.

An earthquake doublet (Mw 7.8 and Mw 7.6) occurred on the East Anatolian Fault Zone (EAFZ) on February 6th, 2023. The events produced significant ground motions and caused major impacts to life and infrastructure throughout SE Türkiye and NW Syria. Here we show the results of earthquake relocations of the first 11 days of aftershocks and rupture models for both events inferred from the kinematic inversion of HR-GNSS and strong motion data considering a multi-fault, 3D geometry. We find that the first event nucleated on a previously unmapped fault before transitioning to the East Anatolian Fault (EAF) rupturing for ~350 km and that the second event ruptured the Sürgü fault for ~160 km. Maximum rupture speeds were estimated to be 3.2 km/s for the Mw 7.8 event. For the Mw 7.6 earthquake, we find super-shear rupture at 4.8 km/s westward but sub-shear eastward rupture at 2.8 km/s. Peak slip for both events were as large as ~8m and ~6m, respectively.
State regulation of land relations in the Kuban Cossack army in the middle of the 19th – at the beginning of the 20th century
Authors: Voronyansky Olexander , Bondar Natalia
Published: March 2023

Research aim. The article aims to investigate the measures of the government of the Russian Empire in the field of land relations in the Kuban region, which were aimed at the elimination of the traditional Cossack land system for the natives of the Zaporizhian Military Region.

Research methodology. After the peasant reform of 1861, the state's attack on the traditional Cossack land structure intensified significantly. The scientific hypothesis that in fact the process of "decolonization" in the Kuban was determined by this policy and began as early as the middle of the 19th century was confirmed. In fact, the Russian government pursued a policy of successive liquidation of the land privileges of the Cossacks. As a result, sharp contradictions were constantly growing in the field of land relations, which split the Cossack community into antagonistic social groups.

Scientific novelty.For the first time in Ukrainian historiography, the main steps of the government of the Russian Empire in the field of land relations regulation in the Kuban region in the second half of the 19th - at the beginning of the 20th century were considered. It is shown that this policy was aimed at the gradual systematic liquidation of the traditional Cossack land system for the natives of the Zaporozhye Military Region as the collective land property of the Cossack army.

Conclusions. In the period under review, the policy of the tsarist government of Russia in the field of land relations in the Kuban was actually aimed at eliminating the land privileges of the Cossacks, which were the basis of the Cossack way of life and supported the relative social stability of the Cossack community. In fact, it can be defined as "telling". The reforms of the 1860s and 1870s brought the Cossacks on an equal footing with the civilian population in matters of land use. At the same time, public land funds were reduced, the allotments of ordinary Cossacks decreased, which led to the deterioration of the economic base of the Cossack army.

Against the background of the rapid concentration of land resources in the ownership of the upper layer of the non-urban rural bourgeoisie, the majority of the Cossacks never received land as private ownership and continued to use it as communal members. And although the Kuban Cossacks' relatively good supply of land allowed most of them to remain above the poverty line at the time, state policy in the field of land relations contributed to the rapid accumulation of sharp contradictions that split the Cossack community into antagonistic social groups.

The results of this split clearly manifested themselves during the civil war in Russia, when most of the ordinary Cossacks did not support either the tsarist government, the White Movement, or the attempts of the Kuban Cossack leadership to create an independent Kuban Cossack Republic based on traditional Cossack law.

Non-Complex Cost-Effective Energy Monitoring using the Internet of Things
Authors: Hertzog Pierre E , Swart Arthur J
Published: March 2023

Energy monitoring is vital to identifying ways of reducing energy consumption. This may lead to a reduction in the use of non-renewable energy sources (such as coal), increasing the lifespan of current energy storage systems (such as batteries) and reducing financial costs (such as electrical utility costs). Current commercial monitoring systems may prove too complex or too expensive for the average homeowner to install and use. How can the internet of things, therefore, be used to identify sources of energy consumption? The purpose of this paper is to describe the design and setup of a non-complex cost-effective energy monitoring system for a residential home environment. This may enable homeowners to identify unwanted energy consumption and thereby reduce their electrical utility bills. The system incorporates an Arduino Uno Board, ESP8266 WiFi module and a cloud server called ThingSpeak. No physical wiring connections are needed, as only a current transformer sensor needs to be hooked around the main AC supply line from the electrical utility provider. No PC data storage is required, as the data is stored on the cloud server. The only key requirement is internet connectivity so that the WiFi module may connect directly to the cloud server where all data is captured and presented.

Published: March 2023

In this work data-driven approaches to identify the gender of author of Russian text are investigated with the purpose to clarify, to what extent the machine learning models trained on texts of a certain genre could give accurate results on texts of other genre. The set of data corpora includes: one collected by a crowdsourcing platform, essays of Russian students (RusPersonality), Gender Imitation corpus, and the corpora used at Forum for Information Retrieval Evaluation 2017 (FIRE), containing texts from Facebook, Twitter and Reviews. We present the analysis of numerical experiments based on different features(morphological data, vector of character n-gram frequencies, LIWC and others) of input texts along with various machine learning models (neural networks, gradient boosting methods, CNN, LSTM, SVM, Logistic Regression, Random Forest). Results of these experiments are compared with the results of FIRE competition to evaluate effects of multi-genre training. The presented results, obtained on a wide set of data-driven models, establish the accuracy level for the task to identify gender of a author of a Russian text in the multi-genre case. As shown, an average loss in F1 because of training on a set of genre other than the one used to test is about 11.7%.
A Fuzzy Approach to Prioritisation of Security Requirements in a Constrained Agile Software Development Environment
Authors: Naicker Nalindren , Maharaj Manoj
Published: March 2023

Requirements Engineering (RE) is software engineering process that takes place early namely, during the planning phases of software development. The spate of hacking incidents, more especially the ransomware infections, recently has suggested a more robust approach to web application security during RE. This will not only prevent these vulnerabilities but also the necessary rework after a hacking incident. The prioritisation process in RE is instrumental in ensuring if a security requirement gets implemented or is kept on hold indefinitely. A desktop literature review revealed ample scope for fuzzy TOPSIS as a security requirements prioritisation technique. The aim of this research study was to assess the viability of a new and more inclusive technique of more precisely ranking security requirements. A fuzzy automated tool was developed to test this new approach to ranking security requirements. The method will ensure the implementation of the most important security requirements to secure the system. The Design Science Research Methodology guided the development of the automated fuzzy software tool. The automated tool was evaluated in a qualitative study at 17 software development companies. The researcher used structured interviews and document reviews as the primary research instruments. Qualitative data was analyzed deductively using content analysis. It was found that an immediate benefit of the tool is that it prevented biases and autocratic leaders from influencing decision making during security risk analysis. The study concluded that the automated fuzzy tool showed positive results for ranking security requirements in Agile RE. Further research on the usability of the software tool is recommended.

Published: March 2023

One of the widely discussed issues in the current world is the quality of teacher’s professional competences, which is closely related to the possibilities and ways of their evaluation. The identification and evaluation of teacher's key professional competences is of particular interest for the team of researchers at Constantine the Philosopher University in Nitra (Slovakia) within the research project APVV-14-0446 Assessment of teacher's competences, the output of which should be a new concept of the assessment of teacher's professional competences and the design of a relevant set of assessment tools. The intention of the research team is to encourage teachers' evaluators to use more reflective approach to this task in order to ensure deeper feedback for teachers on their performance. The project started in 2015 and is still in progress. So far the team has managed to agree on 10 professional competences of teacher, which they consider to be the key ones for the high quality performance of teachers. Then, a new stratified approach to their assessment was developed, and for each of the competences, a set of assessment instruments: Assessment Sheets for evaluators, Self -Assessment Sheets for the evaluated teachers and instructions for Post-Observation Interview of the evaluator with the teacher, was designed. The instruments are currently being piloted in schools. The paper deals with partial results of the piloting of the three tools designed to assess the teacher's competence: can develop pupil's personality and their competences. The piloted tools will be introduced in more details and the issues connected with their acceptance and use by school staff and managers will be discussed.

Authors: Malunda Paul Netalisile , Atwebembeire Juliet
Published: March 2023

The study examines the influence of instructional resources on teacher effectiveness in government-aided secondary schools in Uganda and specifically the extent to which availability and utilization of instructional resources influence teacher effectiveness. A descriptive cross-sectional survey design was used in which 82 head teachers and 1024 teachers were selected using multistage sampling. Survey, interview, observation and document analysis methods were used to collect data. Quantitative data were analyzed using descriptive statistical analysis and ordered logistic regression, while content analysis was used to analyze qualitative data. The findings suggest that availability and utilization of instructional resources significantly contribute to teacher effectiveness although instructional resources are inadequate and not properly utilized. To enhance teacher effectiveness, the Ministry of Education and Sports (MoES) should continuously train teachers on use and improvising of instructional resources. Government should construct more libraries and science laboratories especially for Universal Secondary Education [USE] schools to promote easy accessibility of textbooks by learners and teachers and practical teaching of science subjects.

Let a, b ∈ Z and p be a prime number such that a and b are not divisible by p. In this work, we give a congruent property modulo a prime number p of the gibonacci number defined by Gn = Gn−1 + Gn−2 with initial condition G1 = a, G2 = b. We show that a the gibonacci sequence satisfying Gkp−(p/5) ≡ Gk−1 (mod p) for all positive integer k and such odd prime p ≠ 5 if and only if a ≡ b (mod p). Moreover, for each odd prime number p, we give a necessary and sufficient condition yielding Gkp−(p/5) ≡ Gk−1 (mod p). We also find a relation between the sequences in the same equivalent class in modulo 5 constructed by Aoki and Sakai [1] that leads to such congruent property.

Published: March 2023

The composition and abundance of phytoplankton in the waters are strongly influenced by the supply of phosphorus and light intensity, so observations were made to obtain the optimum phosphorus concentration with a certain level of light which caused the high abundance of phytoplankton in Lake Cikaret. A 2 x 2 factorial design was used to see the effect of three levels of phosphorus (0.03 mg/L, 0.09 mg/L, and 0.15 mg/L) and three levels of light (30%, 70% and 100% luminance). on the abundance and composition of phytoplankton. The parameters observed were the abundance and composition of phytoplankton, dissolved oxygen, pH, temperature, turbidity, light intensity, and total phosphorus. The results showed that the addition of phosphorus in the waters increased the abundance of phytoplankton. Chlorophyta was high in the first week, then Bacillariophyta and Chlorophyta were high in the second week until the end of the observation. Synedra sp. (Bacillariophyta) tended to be high in abundance at a low light intensity, while Mougeotia sp. (Chlorophyta) tend to be high at all light intensities.
Economic Valuation of Sun Bear (Helarctos malayanus) and Sumatran Elephant (Elephas maximus sumatranus) Based on Maintenance Cost Approach

Published: March 2023

Sun bear (Helarctos malayanus) and sumatran elephant (Elephas maximus sumatranus) are two species with high population decline due to poaching and illegal wildlife trade. It is still difficult to enforce laws related to hunting and wildlife trade due to legal standardization that can be used as an economic basis for lawsuits. One method of quantifying the economic value of animals can be done through an economic valuation process. This study aims to examine the economic value of sun bears and sumatran elephants based on a maintenance cost approach. The research was conducted at the conservation institutions of Medan Zoo, Siantar Zoo, and PPS Tashikoki from February – May 2021. The method used in the study was to manage conservation institutions to obtain the amount of cost allocation for animal care that refers to the five principles of animal welfare. The results showed that the sun bear's economic value based on its maintenance cost for 2 years reached Rp. 76,760,000 and for the sumatran elephant, it reached Rp. 621,730,000. The highest maintenance cost allocation for these two species is in the feed allocation. This high economic value indicates a disproportionate amount of fines given to the perpetrators of hunting and illegal wildlife trade, which has implications for weak legal products and does not cause a deterrent effect.

Published: March 2023

This article discusses the environmental assessment caused by the commercial use of groundwater by the community as landowners. In the future, this practice must receive direction and responsibility from the government as policymakers to prevent and repair environmental damage, especially habitat damage and species in strengthening the principle of "paying for commercial groundwater" with the REA methodology to assess and compensate for environmental damage. This method, developed by the National Oceanographic and Atmospheric Administration (NOAA), uses the scale of remediation required to compensate for past, current and future damage. The compensation approaches are the services approach (or the resources approach) and the valuation approach (the value-to-value and value-to-cost approach). The results show that the change in residential land is 0.16%, or 25 ha. The total area of changed settlement/land built up has decreased the function of land which was originally secondary/logged-over dry land forest to become settlement/land built up. Furthermore, there was a decrease in secondary/logged-over dry land forest to open field of 0.03% or 3.1 ha, so that the total area of secondary/logged-over dry land forest decreased by 0.19% or 28.1 ha.

Flood is number one Indonesian natural disaster in the last 10 years and its occurrence at Manokwari is frequently reported. Biophysical condition is playing a key role in carrying capacity of this catchment area.This study is to determine biophysical characteristics of Wosi Watershed to manage and mitigate flooding in Manokwari. Spatial analysis and field observation methods were used to collect the data. Biophysical variables are rainfall, watershed morphometric, slope, and land used. Carrying capacity is measured using flow regime coefficient and annual flow coefficient. The results showed that the heavy rainfall (> 100 mm) throughout the ten years with 10.5 wet months at average resulting very wet tropical climate. This watershed has an area of 2,346.32 ha, its circumference of 29.95 km2 with river length of 8.38 km resulting 0.33 (triangle) and 1.027 (triangle) for Rc and Re, respectively. This morphometry is rectangular and slightly oval(triangular) formed of four rivers with drainage pattern of dendritic, which resembles the shape of a tree branch/twig. Steep slopes are dominant (58.5%), with non-forest area (62%) of the flat and steep slope for settlement (698 ha), and flat slope for mixed dry farming (707 ha). From 2016-2020, river water flow changes rapidly from low to very high to generate flooding, but the carrying capacity is sometime changeable from good to bad. Water drainage, retaining walls, replantation, early warning system, and flooding leaflets mitigation campaign, are structural and non-structural mitigation could be parallelly conducted to manage and mitigate the flooding risks in future.

Colegialidade dos Bispos a Serviço da Igreja
Authors: Rito Honório
Published: March 2023

Já se disse que o Concílio Vaticano II deveria ser e de fato foi o Concílio dos Bispos, em certa oposição ou talvez, como seja mais justo, em complementação ao Vaticano I que foi antes o Concílio do Papa. Essa linguagem tomada em sentido estrito poderia ser estranha. Contudo, num sentido mais geral, não podemos negar que o pólo que atraiu e concentrou as atenções no Vaticano I foi a autoridade do Papa. Êle foi e ficará sempre como o Concílio do primado e da infalibilidade do Papa. Desde o início êle foi, de certo modo, polarizado por êsse centro de atenções, e cremos que, mesmo se o seu processo tivesse normalmente chegado até o fim, êle poderia talvez ter atenuado um pouco, mas não teria perdido a sua tônica. Êle era como que o coroamento de um longo processo histórico que não podia deixar de realizar-se. Daí, dizer que só por circunstâncias fortuitas o Vaticano I não nos deixou uma visão doutrinal mais completa sobre a constituição hierárquica essencial da Igreja poderia ser um desconhecimento da orientação geral do Vaticano I...

The aim. To assess the effect of glucose-electrolyte composition with plant extracts having antioxidant activity on the hemodynamic parameters of vertebrobasilar system during the incrementally increasing submaximal exercise test.

Materials and methods. The study included 12 athletes (6 candidates for master of sports and 6 masters of sports) aged 18–22, who have been engaged in orienteering for 10 years and more. Time of aerobic exercise – 2 hours a day, five days a week. The study subjects performed an incrementally increasing submaximal exercise test and also submaximal exercise test with the preventive intake of a glucose-electrolyte composition with plant extracts having antioxidant properties. To assess the hemodynamic parameters in all study subjects we used Doppler ultrasound of the cerebral vessels, evaluating vertebrobasilar system blood flow, exercise gas test in the modification of hypo- and hyperventilation, and also positional test.

Results. A single intake of glucose-electrolyte drink under conditions of incrementally increasing exercise test contributed to the manifestation of a homeostatic effect in hemodynamic parameters of the vertebrobasilar arteries. It is evidenced by the approximation to the pre-exercise level of maximum systolic velocity and average blood velocity in the breath-holding test, of the diastolic blood velocity in the hyperventilation test, and of the pulsatility index in the torsion test, as compared to the isolated submaximal exercise test which caused the change in both velocity indicators and calculated indices during the functional tests.

The article considers the main mechanisms underlying the change in arterial hemodynamic parameters caused by incrementally increasing load, as well as describes the proposed mechanisms arising from the combined effect of an incrementally increasing load and the intake of a glucose-electrolyte composition with plant extracts having antioxidant activity.

Conclusion. It was shown that using glucose-electrolyte drink contributed to the restoration of hemodynamic parameters of the vertebrobasilar arteries after an incrementally increasing submaximal exercise test.
Alexithymia and psychosomatic diseases in adolescents: primary headaches
Authors: Gorobets E. A. , Esin O. R.
Published: March 2023

Background. Alexithymia is traditionally regarded as a factor which influences the development of psychosomatic diseases and contribute to a more severe and prolonged course of somatic diseases the high level of alexithymia indicates the deficit in  cognitive processes associated with awareness, exteriorization and regulation of feelings and emotions. In recent years, a lot of research has been conducted on the comorbidity of alexithymia and psychosomatic diseases in adults, but there are very few studies in relation to children and adolescents.

The aim. To analyze psychosomatic diseases associated with the high level of alexithymia in adolescents, to study the correspondence of alexithymia and central sensitization (CS) in adolescents with primary headaches (migraine and tension-type headache).

Methods. The diagnosis of headache was based on the criteria for the International Classification of Headache, 3rd edition. The study group included 84 adolescents, average age – 14 [13; 16] (51 females, 33 males). CS was assessed using the Russian version of “Central Sensitization Inventory” (2020) for adolescents. Alexithymia was  assessed using the Russian version of “Alexithymia questionnaire for children” (2019). Headache intensity was measured using the Visual Analogue Scale. There were also assessed the number of months and days per month with headaches; duration of night sleep; age of phrasal speech start.

Results and discussion. The results showed the direct correlation between levels of alexithymia and central sensitization (rS = 0.49; p = 0.00001), the number of days with headaches per month and central sensitization severity (rS = 0.24; p = 0.027). There was no significant correlation between alexithymia severity and headaches duration (rS= 0.06; p = 0.5), no reliable results on the correspondence of alexithymia severity, age of phrasal speech start and nocturnal sleep.

Conclusion. A high level of alexithymia is observed in adolescents with various somatic diseases. Primary headaches are associated with a high level of alexithymia and the severity of central sensitization. Pediatricians and neurologists should be advised to assess the level of alexithymia and central sensitization in adolescents with headaches.

Background. The concept of multistage surgical treatment of patients has been established in surgery rather recently and therefore the discussions on the expediency of using a particular surgical technique in a specific situation still continue. Vacuum-assisted laparostomy is being widely implemented into clinical practice for the treatment of abdominal compartment syndrome, severe peritonitis and abdominal trauma, but the indications and advantages of this method are not clearly defined yet.

The aim of the study. To conduct a systematic review and meta-analysis on the comparison of the effectiveness of vacuum-assisted laparostomy with various variants of relaparotomy and laparostomy without negative pressure therapy in  the  treatment of patients with urgent abdominal pathology and abdominal trauma complicated by widespread peritonitis, sepsis or compartment syndrome.

Material and methods. A systematic literature search was conducted in accordance with the recommendations of “Preferred Reporting Items for Systematic Reviews and Meta-Analyses”. We carried out the analysis of non-randomized (since January 2007 until August 6, 2022) and randomized (without time limits for the start of the study and until August 6, 2022) studies from the electronic databases eLibrary, PubMed, Cochrane Library, Science Direct, Google Scholar Search, Mendeley.

Results. Vacuum-assisted laparostomy causes statistically significant shortening of the time of treatment of patients in the ICU and in hospital and a decrease in  postoperative mortality compared to other variants of laparostomy without vacuum assistance.

Conclusion. To obtain data of a higher level of evidence and higher grade of recommendations, it is necessary to further conduct systematic reviews and meta-analyses based on randomized clinical studies.
