Objective. The aim of this study is to assess the safety of the use of regional anesthesia for performing carotid endarterectomy (CEA) in patients in the acute phase of ischemic stroke.

Material and methods. The study included 66 patients in the acute phase of ischemic stroke (atherothrom-botic subtype according to the TOAST classification) who underwent carotid endarterectomy. The inclusion criteria for the study were as follows: acute phase of atherothrombotic ischemic stroke (first 28 days), ipsilateral symptomatic ≥ 50% stenosis of the internal carotid artery, 1-4 points neurological deficit according to the modified Rankin Scale (mRS), 1-13 points neurological deficit according to the National Institutes of Health Stroke Scale (NIHSS), size of the cerebral ischemic lesion ≤ 4 cm. This single-center prospective cohort study compared two anesthetic approaches, regional anesthesia (RA, 46 patients) and general anesthesia (GA, 20 patients). The RA techniques included ultrasound-guided superficial and deep cervical plexus blocks on the side of the surgery.

Results. The study found no significant differences in the baseline patient characteristics, surgery techniques and clinical outcomes between the groups. There were no neurological or cardiovascular toxic reactions to the local anesthetics. Conversions from RA to GA were not performed. In the RA group, recurrent ipsilateral ischemic strokes, myocardial infarctions, wound hemorrhagic complications and lethal outcomes did not occur.

Conclusion. This pilot study has demonstrated the safety of RA for performing CEA in patients in the acute phase of ischemic stroke. RA provides adequate neuromonitoring and timely intraoperative recognition of «new» ischemic complications. To compare the efficacy of RA and GA for performing CEA in patients with acute ischemic stroke, large randomized controlled trials are needed.

Authors: Perepelitsa S. A.
Published: December 2022

Aim of the study: to develop an additional professional competence «Emergency care in cardiac arrest» and to evaluate a set of tools for its development among the graduating students majoring in general medicine (code 31.05.01).

Material and methods. The study was done in two stages. During the first stage, within the framework of PC (professional competence)-11 «Readiness to participate in providing first medical aid in conditions requiring urgent medical intervention» an additional professional competence «Emergency care in cardiac arrest» was developed with the definition of performance assessment. During the second one, the scientific research was conducted at the medical institute of the Immanuel Kant Baltic Federal University during the study of Anesthesiology, resuscitation, and intensive care, which has been included in the block 1 discipline (module) list, being a basic part of the General Medicine curriculum (code 31.05.01). The study involved 140 six-year students majoring in general medicine (code 31.05.01). The students were divided into two groups. The main group included 80 students who studied in 2021 (average age 25±1.5 years), while the control group comprised 60 participants who studied in 2019 (average age 25.9±1.6 years, retrospective analysis).

Results. An additional professional competence «Emergency care in cardiac arrest» and its stratified structure have been developed. Specific elements were elaborated for each component stratum. Based on the developed elements, which were mastered by the student in the process of training, the necessary competence was developed. The novel pedagogical technologies in the curriculum contributed to more effective learning and development of the competence. The levels of development of additional professional competence «Emergency care in cardiac arrest» differed between the groups. Most students in the control group had a threshold level of competence. The basic and advanced levels of competence were significantly higher among the students in the main group compared with the control group (P<0.05).

Conclusion. We have shown the necessity of developing an additional professional competence «Emergency treatment in case of cardiac arrest» within the «Readiness to participate in providing first medical aid in conditions requiring urgent medical intervention» PC-11. We have successfully implemented and validated in practice the system of development of additional professional competence using pedagogical innovations, including those based on advanced information and communication technologies.

La autonomía literaria, un ídolo sin el cual no habría literatura moderna

¿Se puede hacer una reflexión sobre laideología luego que se han agotado los recursosinterpretativos que impuso la filosofía dela sospecha? Este ensayo responde de formaafirmativa a esta interrogante. En el mismo,se asume que las dos tareas que distinguenal ejercicio filosófico, construcción de idealesy demolición de ídolos no pueden existir deforma independiente. El ideal y el ídolo sonla cara y la cruz de un mismo concepto. Loque voy a analizar es una falsificación, unainversión, una distorsión sin la cual una prácticano puede funcionar. La inversión, falsificación,distorsión, que voy a examinar eneste ensayo involucra el ideal de la autonomíaliteraria sin la cual la obra de arte modernasería inconcebible. La tarea que me he propuesto:analizar una distorsión que más queimposibilitar permite la existencia de ciertapráctica, me coloca, sitúa, ante el problemade la ideología en un ángulo singular. Lo queafirmo conlleva la siguiente consecuencia: elídolo, la imagen distorsionada de algo, resultaesencial para su funcionamiento ideal. Delos múltiples enfoques que se pueden usarpara pensar el mito de la autonomía literariaaquí se prefiere uno: aquel que se centra enlos gestos que propone la obra —retóricos,semánticos, prosódicos— para desligarse delantes que la precede y del afuera que la circunscribe.Aquí se explora la relación que laobra, el texto, tiene con sus antes y su afueratanto en la etapa clásica como en la moderna.

The International Food Aid Policies of the United States
Authors: Gabos Emily
Published: December 2022

The United States’ (US) current food aid foreign policies do not allow it to fulfill the primary goal of providing food aid to people in other countries who need it. The US’s current policies encourage dumping its agricultural surpluses into other countries’ markets in the form of food aid. Although this practice may further US economic pursuits, it undermines the goals of the US’ food aid programs by distorting markets and undermining producers in recipient countries. These countries then become dependent on US food aid, which further tilts the global market toward US agricultural products. US food aid foreign policy also exhibits structural issues, such as monetization and requirements that food aid be purchased from US farmers and shipped on US vessels. These practices waste money that the US could have spent on feeding more people. Drawing on government statistics, policy experts’ opinions, news reports, and recent examples of food aid policies’ effects, this brief delineates three policy options to more closely align US food aid foreign policy with its intended objectives. It will ultimately recommend that the US resolve its structural mismanagement issues impeding the efficacy of its food aid programs and divert funds away from development projects and toward disaster relief.

At the turn of the century, lesbian characters were appearing in popular American media ranging from television to film. However, many of these depictions were far from supportive. Instead, the lesbian identity of characters in American cinema harbored negative stereotypes that acted as an attack on the third wave feminist movement.

This essay analyzes depictions of lesbians in film at the end of the 20th century as it relates to the third wave feminist movement of the 1990s. More specifically, it argues that stigmatized depictions of lesbians in American cinema reproduced the underlying anxieties of the third wave feminist movement. Through the analysis of two films: Election (1999) and Mean Girls (2003), as well as the feminist theory of bell hooks, this essay explores the fears and anxieties of the revitalized feminist movement. Both films served as a backlash against the feminist movement by using skewed depictions of lesbians to further establish negative emotions towards the movement. These political and sociological anxieties of the feminist movement developed into exaggerated characteristics within lesbian supporting characters. As a result, stigmatized depictions of lesbians delegitimized their role as leaders of the third wave feminist movement.

Published: December 2022

The properties of single shear specimens connected by wooden nail frictional welding and twist nails were studied. The single shear properties of the specimens connected by wooden nail welding were lower than that of the twist nail specimens. The single shear capacity of the wooden nail welding specimen was determined by calculating the method of design value of the bearing capacity of the pin connection. Furthermore, the flexural properties of the wooden nail welding laminated timber were analyzed. Due to the larger diameter of the wooden nails compared with the twist nails, the wooden nail welding laminated timber in the elastic phase had higher stiffness. The elastic modulus of the wooden nail welding laminated timber exceeded the average elastic modulus of the constituent lumber pieces by 9.46%. The number of wood lumbers in wooden nail welding laminated timber had little effect on the elastic modulus of laminated timber, but the nail spacing had a certain effect. Therefore, in future research, it is recommended to use the construction method of twist nail connection to design the wooden nail welding laminated timber. In addition, the nail spacing should refer to the GB 50005 (2003) standard and the wood structure design manual.

Published: December 2022

Cellulose is a potential alternative to petroleum-derived polymers, and cellulose membranes are used in many applications such as sensors, flexible materials, and functional membranes. Most bottom-up methods are energy-, chemical-, and time-intensive compared to top-down methods for preparing cellulose membranes. Additionally, most methods to improve the hydrophobicity of cellulose membranes to increase their lifetime are complex and require large amounts of organic solvents. To balance sustainability, degradability, and service life from a whole life cycle perspective, which is the biggest challenge for the industrialization of cellulose membranes, a top-down approach was used here to prepare cellulose membranes using camphor pine, walnut, and loofah materials. The effect of low temperature heat treatment on the prepared membranes’ wettability and water stability were investigated. The results showed that the water stability of loofah cellulose membrane was influenced by both surface and internal wettability due to the non-homogeneous structure. The heat treatment temperature of 200 °C for loofah cellulose membrane, 150 °C for camphor pine cellulose membrane, and 225 °C for walnut cellulose membrane was more effective.
“Make up Your Own Mind about Gavrilo!”
Authors: Bartulović Alenka
Published: December 2022

Drawing on recent scholarly critiques of dominant Balkanist understandings of memory work in post-war societies and focusing on individuals as active managers of transmitted memories, this article illustrates the dynamic nature of how the Sarajevo assassination and Gavrilo Princip are remembered in Sarajevo. It offers ethnographic insights into the everyday effects of power struggles between popular and official memories and responds to calls to explore affective states brought about by the politicization of the past in particular settings. Without denying the importance of memory in post-war Bosnia-Herzegovina, it nevertheless points to the relevance of exploring uncertainty, doubts, disinterest, and silences for ethnographic research on memorialization processes in post-conflict societies and beyond.

Published: December 2022

This study aimed to analyze the business marketing relationship between modern suppliers and SME retailers to empower and strengthen SMEs in Indonesia. The theoretical framework is the relationship marketing model developed by Morgan and Hunt (1994). This framework is based on trust and commitment as the two key mediating variables. The study surveyed 250 SME retailers as respondents selected using purposive sampling. Furthermore, hypotheses were tested using path analysis. The findings showed that trust and commitment to business partnerships mediate the effect of influence strategy on loyalty to business partners and economic performance. The influence strategy significantly affects the business performance of the involved parties. Therefore, strategic business partnerships with modern suppliers improve SME retailers’ business performance.

Published: December 2022

This study employs the logistic regression method to examine the effect of financial inclusion on the level of poverty in Niger State of Nigeria based on cross-sectional data randomly collected from 624 respondents across 224 towns and villages in 12 local government areas (LGAs) of the state. The estimation results illustrate that financial inclusion (proxied by bank account ownership, including access to bank, credit, and mobile phone) is significantly and negatively related to the level of poverty. This empirical outcome is further validated by the results of the Probit regression technique which show a significant negative relationship between financial inclusion and poverty in the state. Based on these empirical findings, the study recommends policies which include broadening bank coverage, softening credit requirements, and enhancement of people’s access to mobile phone and internet services in rural areas of Niger state.
Investigation of Fractal Market Hypothesis in Emerging Markets: Evidence from the MINT Stock Markets
Authors: Karaömer Yunus
Published: December 2022

This study aims to investigate the market efficiency of emerging stock markets, namely the Mexico, Indonesia, Nigeria, and Turkey (MINT) stock markets based on the Fractal Market Hypothesis. For this purpose, the ARFIMA and ARFIMA-FIGARCH type models are used to analyze the MINT stock return series. In this study, the dataset encompasses the daily frequency data of the MINT stock market indices from January 12, 2018, to January 12, 2022. The empirical findings show that long memory is reported for the MINT stock returns. The long memory in the returns implies that the MINT stock prices follow a predictable behavior that is consistent with the Fractal Market Hypothesis. The long memory in the volatility implies that the uncertainty or risk is an important factor in the formation of price movements in the MINT stock prices. Moreover, the MINT stock prices consist of the effect of shocks and news that occurred in the recent past. Thus, this study contributes to investors, academics, and market regulatory authorities. Besides, as far as we know, the current literature on the analysis of the fractal market hypothesis to explore the efficiency of the MINT stock markets has not been found.

The mantle source of fluids for the U-bearing Na-metasomatites of the central-ukrainian uranium province inferred from Pb, Sr and Nd isotope composition
Authors:   M.P. Semenenko Institute of Geochemistry, Mineralogy and Ore Formation of the NAS of Ukraine, Shumlyanskyy L.V.
Published: December 2022

The results of the determination of Sr, Nd and Pb isotope composition in U-bearing Na-metasomatites of the Central-Ukrainian Uranium Province are reported. In total, 23 samples representing 5 deposits, were studied. The obtained results reveal the similarity of the Sr and Nd isotope composition between the metasomatic rocks and their host rocks. However, metasomatic rocks in general have a lower 87Sr/86Sr ratio that indicates a presence of a more “primitive” juvenile component in their composition. The constructed Pb-Pb isochron has yielded an age of 1810 ± 17 Ma, in good agreement with the previously obtained results. This age confirms the simultaneity of the formation of Na-metasomatites and the emplacement of the numerous mafic dykes widely distributed in the area. Apparently, metasomatic fluids were generated in the upper mantle and their ore potential was inherited from the mantle source. The formation of the huge volumes of the mantle-derived fluids is linked to the establishment of the Prutivka-Novogol large igneous province and emplacement of the large anorthosite-mangerite-charnockite-granite plutonic complexes (Korosten and Korsun-Novomyrhorod complexes) that also belong to the province.

The geological structure and prospects of a group of rare earth objects of exogenous origin, unconventional for the Ukrainian industry, are considered. According to the authors, this is mainly the clay weathering crust of granitoids and other aluminosilicate rocks, which contains sorbed or close to them elements of the yttrium group. A feature of ores of this type that may interest investors is the possibility of relatively simple and inexpensive extraction of REE. As an example, a brief description of specific objects within the Azov part of the Ukrainian shield and on its border with Donbas is given. This is the weathering crust of subalkaline rare-metal granites of the Yekateriniv and Starodubiv massifs, aluminosilicate metamorphic rocks of the Valerianiv area, and tectonic mélange zone argillites of the Zhogoliv area. The Y-Ta-Nb type of deposits was established on the massifs, and mainly yttrium-earth deposits on the metamorphic rocks. The actual results of the analytical research made it possible to draw conclusions about the qualitative and quantitative composition of ores and forecast resources. A comparison of industrial technological methods of extracting Y and ∑REE from loose ores of the Zhogoliv ore deposit was made. The expediency of further searches and research in order to expand the mineral raw material rare earth base of Ukraine is substantiated.
Xeno-autolithic nodules from kimberlites of the “Nadiia” pipe (Eastern Azov region, Ukraine)

Xeno-autolithic nodules from kimberlites of the Nadiia pipe (the Eastern Azov region, Ukraine) have been investigated. Based on petrographic and petrochemical criteria it was concluded that the analyzed nodules were formed according to the principle of the “snowballs” formation in the apical parts of the penetrating magma column at various pressures and temperatures. Nodules originated around xenocrysts, xenoliths and viscous magmatic clots by overgrowing them with orbicular shells under conditions of a mobile medium and flotation gas-liquid differentiation. The nodule shells are represented by porphyric kimberlite, composed of porphyric pseudomorphs of diaphtoritic minerals after olivine, clinopyroxene, phlogopite, biotite and ilmenite, and a groundmass consisted of micron-sized crystallites of calcite, barite, serpentine, perovskite, phlogopite, amphibole, chlorite, formed by crystallization of kimberlite glass of heterogeneous composition. The groundmass also contains newly formed feldspar and quartz. Accessory minerals include zircon, apatite, and rutile. Ore minerals are represented by magnetite, titanomagnetite, ilmenite, nickel and copper sulfides. Due to the assimilation of carbonate rocks by the melt, the composition of the shells, in the direction from the center to the edge of the nodules, changes from serpentine, through chlorite-serpentine to silicate-carbonate. The initial portions of the melt with olivine and phlogopite megacrysts were successively transformed into a homogeneous one. The estimated depth of kimberlite magma generation did not exceed 150 km at the initial crystallization temperatures of the silicate component of 1300-900 °C. Vitrification of the nodules groundmass in the crater zone of diatreme, estimated using monomineral phlogopite geothermometer, occurred at temperatures of 650-550 °C. The absence of diamond paragenesis minerals in nodules, in combination with other mineralogical, petrological and petrochemical criteria indicates that kimberlites of the «Nadiia» pipe are diamond barren.

The microelement composition (Pb, V, Cr, Zn, Mn, Cu) of the mountain-podzolic brown earth soils of the Chornohir and Marmarо reserve massifs of the Carpathian Biosphere Reserve was determined: background, under wet and dry moss (Sphagnum palustre L.). The increased content of trace elements (Cu, V, Zn, Mn) in the upper soil layer of the Chornohir massif was determined, which is explained by the presence of a clay component, and the lower content in the Marmaros massif — the presence of carbonates. Ranked series were constructed by the dispersion coefficient of microelements in soils covered with wet and dry moss Sphagnum palustre L. It was established that the soil under dry moss is practically not depleted of microelements, but in the presence of rains it becomes wet again and the sorption process resumes. It was found that the soils under the wet moss of the Chornohir massif are most depleted in Mn, Cu, and Zn; and the Marmaros massif — Mn, Pb, and V. The geochemical behavior of the studied microelements in soils under wet moss was analyzed. It was concluded that wet moss has a selective ion exchange, is a geochemical barrier, and that is why lithochemical search and monitoring works should be carried out in the areas covered with wet moss, taking into account the established features.

A narrow-band high frequency amplitude modulation as a model of vibration signal is considered. Use of Hilbert transform for the demodulation of periodically non-stationary random signal (PNRS) is discussed. Relations for spectral and covariance components of model signal, its Hilbert transform and cross-covariance components are obtained. Quadratures for modulation signal are extracted and analyzed. It is shown, that the Fourier coefficients of the auto-covariance functions of a signal and its Hilbert transform are the same and its cross-covariance functions differ only by a sign. The square of the modulus of the analytical signal is not a “squared envelope” in the known sense. A “squared envelope” in this case is a random process, whose mathematical expectation is equal to twice the variance of the raw signal. This results in an identity of cyclic spectrums of variances for analytic and raw signals. Thus, the Hilbert transform cannot be used directly as a demodulation procedure, and the “squared envelope” can be analyzed only as the implementation of a random process using PNVP methods. It is shown that band-pass filtering and the Hilbert transform can be used for extraction of modulating signal quadratures.

Published: December 2022

BACKGROUND AND OBJECTIVES:

Prompt antibiotics have been shown to improve outcomes in pediatric sepsis, which continues to be a leading cause of death in children. We describe the quality improvement (QI) efforts of a single academic children’s hospital to improve antibiotic timeliness.

METHODS:

Using the electronic health record, we report time from order to the administration of stat intravenous (IV) antibiotics from 2012 to 2020 using statistical process control charts. We describe QI interventions initiated over the study period. These include the formation of a Pediatric Sepsis Committee, routine use of automated dispensing machines for stat IV antibiotics, creation of sepsis order sets, manual and automated sepsis screening implementation, participation in national sepsis QI collaboratives, creation of difficult intravenous access guidelines, and an automated notification system for charge nurses. As a balancing measure, we assessed stat IV antibiotic use normalized to total emergency department visits and inpatient days.

RESULTS:

Multiple quality improvement interventions were initiated and sustained under the direction of the hospital Pediatric Sepsis Committee. We improved our stat IV antibiotics given within 1 hour of order from 33% in 2012 to 77% in 2019 and maintained this through the end of the study period in July 2020.

CONCLUSIONS:

By using a multipronged quality improvement approach, we demonstrated consistent and sustained improvement in the timely administration of stat IV antibiotics over an 8-year period at our institution. Further study is needed to assess whether this is associated with reduced length of stay or improved survival in children with sepsis.
El vocabulario agrícola del «Diccionario de autoridades» (1770) autorizado con el «Libro de agricultura» de Alonso de Herrera
Authors: Sánchez-Martín Francisco-Javier
Published: December 2022

Se examina la recepción lexicográfica del Libro de agricultura en la segunda edición del Diccionario de autoridades. La revisión por parte de los académicos de su primer repertorio provocó enmiendas en aquellos artículos agrícolas lematizados, que, fruto de su remodelación, incorporan en 1770 la autoridad de Alonso de Herrera. Paralelamente, el vaciado del tratado geopónico supuso la adición de nuevas entradas con su autorización. El análisis microestructural de los artículos enmendados demuestra su reajuste en la marcación, definición y equivalentes latinos, así como en la revisión de la autoridad herreriana para corresponder con los sentidos lematizados. El estudio de los nuevos contextos alegados, así como de los remodelados, a partir del cotejo con las versiones del libro herreriano impresas entre 1513 y 1768, revela la utilización preferente de las primeras ediciones para ilustrar los tecnicismos geopónicos, así como la alteración de los pasajes, particularmente del inciso parentético introducido para contextualizar la cita.
Problem tożsamości filozofii w koncepcjach przedstawicieli szkoły lwowsko-warszawskiej oraz ich krytyków
Authors:   Akademia Pedagogiki Specjalnej im. M. Grzegorzewskiej w Warszawie, Polska, Drabarek Anna
Published: December 2022

The article presents polemics, concerning the concept of philosophy of the Lviv-Warsaw School (R. Ingarden’s polemic with K. Twardowski’s views on the possibility of forms and limits of cognition of mental states of other people), and three polemics with Łukasiewicz’s concept of trivalent logic: F. Gonseth; Urquhart; T. Bigaj. A polemical analysis of the differences in the understanding of the tasks of philosophy between the Lviv-Warsaw School and Polish neo-Thomism is also presented. The postulate of the neutrality of philosophy in relation to worldview problems leads to non-involvement in religious and political disputes, while the recommendation to avoid speculative issues – to an aversion to statements of a metaphysical nature. M. Przełęcki, considered to be one of the last representatives of the Lviv-Warsaw School, argues against this view.
Double-Sided Glass Gems from the Burial no. 13 of the Kurgan no. 1 of the Group “Bogomol’nye Peski-I”
Authors:   Astrakhan Museum-Reserve, Timofeev Alexey , Treister Mikhail ,   Independent Researcher
Published: December 2022

The article examines five double-sided glass gems found as elements of a bracelet on the left wrist of a child aged 2,5–3 years in the burial no. 13 of the kurgan no. 1 of the “Bogomol’nye peski-I” group near the village of Nikol’skoe, Enotaevskiy District, Astrakhan Region. The inventory of the burial gives grounds for its dating within a broad frame of the 1st – first half of the 2nd century AD. As in the Scythian burials of the Dnieper region, glass gems in the kurgan of the “Bogomol’nye peski-I” group were found in a child’s burial. They were considered by their owners as items of jewelry and amulets, and not as a means for imprinting images. It is worth noting that the images on the sides of the same gem are rarely semantically related to each other, but rather give the impression of a rather random choice of subjects. In many cases, the motives go back to gems of the late Classical and Hellenistic periods. Given the fact that the images on the glass gems were mechanically reproduced from intaglios, there is reason to suppose that these were works of glyptics from the late Hellenistic period, which could theoretically be used for making glass gems at a later period. The uniqueness of double-sided glass gems, on the one hand, and their distribution in the North Pontic region in the 6th–4th centuries BC, on the other hand, give grounds to suggest the possibility of the origin of finds originating from the Sarmatian burials of the Lower Volga region from the workshops of the North Black Sea region, possibly of the Bosporan Kingdom.

Bone Tissue Defects on Human Skulls from of the Eneolithic Burial Ground of the Yekaterinovsky Cape in the South of the Middle Volga Region. Revisiting Specifics of Cultural Traditions
Authors:   Samara State University of Social Sciences and Education, Khokhlov Aleksandr
Published: December 2022

Unusual defects mainly in the form of surface ellipsoid or less commonly sub-circular indentations were recorded on the skulls of mature individuals from the Eneolithic burial grounds in the forest-steppe area of the Volga region (Yekaterinovsky cape). Almost all of the defects are localized on the parietal bones. The origin of the small-sized lesions could be associated with trauma. The large defects occur due to additional surgical prophylaxis by scraping. There are separate cases of classical end-to-end trepanation (burial 57/1, 83). The authors conducted a comparative analysis of the identified defects with similar injuries on the materials from ancient burial grounds of the Volga region (Khvalynsk I, II), other regions and periods of Europe. Ritual character connected to age initiation rites was previously attributed to their origin. This thesis is supported by new source discovery (Yekaterinovsky cape). The probability of the so-called symbolic trepanation is considered. We do not exclude these types of reasons. However, priority in determining the technical content of the period of trauma development that accompanied the ritual is given to other target settings. Their natural appearance was initially associated with “shock symbols” and after the entire ceremony, if necessary, surface trepanation was used for medicinal purposes. Such marginal traditions are usually characteristic of ancient highly organized and influential societies, which is confirmed by archaeological data, in particular, regarding the fame and role of the Khvalyn Eneolithic population in the cultural processes of the central regions of Eurasia. The beginning of the trauma ritual in the Volga region was laid at least in the 6th millennium BC (Yekaterinovsky cape), then adapted and developed by the ancient Khvalyn groups.

Background. Speech development impairment is urgent and common problem in pediatric neurology. Transcranial magnetic stimulation (TMS) is one of the promising treatment variants for children with speech disorders. Objective. The aim of the study is to evaluate efficacy and safety of the developed approaches to TMS usage in the management of children with speech disorders. Methods. It was non-randomized controlled study. It included 46 children with speech disorders aged from 3 to 6.5 years. All children were divided into two groups comparable by gender and age: 26 children of the treatment group received TMS course, 20 children of the control group received treatment with hopantenic acid. All patients with speech disorders underwent psychological and pedagogical evaluation of speech and cognitive development, electroencephalography (EEG) before and after treatment. Moreover, comparative analysis of TMS and nootropic therapy efficacy was carried out. Specialized examination of speech and cognitive development was also performed via E.A. Strebeleva method for psychological and pedagogical diagnosis of children development. Furthermore, we carried out side reactions / adverse events registration according to patients and/or their parents complaints confirmed by physical examination, patient’s behavior observation, data from specially developed questionnaire for assessing child’s behavior and well-being (filled up by parents). Finally, we evaluated brain bioelectric activity recorded by EEG. Results. The study results have shown that it is possible to achieve significant positive dynamics in cognitive and speech development in preschool children with speech disorders in both groups (TMS course and medical treatment). But hereby, TMS treatment has demonstrated significantly higher positive dynamics in two out of the three evaluated parameters. There were no cases of adverse events in TMS group leading to early course discontinuation. Conclusion. TMS is non-invasive and safe method for treatment of children with speech disorders. This study has demonstrated the efficacy of the method in the field of personalized management of children with impaired speech and cognitive development.
A New Epidendrum (Laeliinae-Orchidaceae) from the Extensively Collected Itacolomi peak, Minas Gerais, Brazil
Authors: Pessoa Edlley M. , Pedrosa Luciano
Published: December 2022

Abstract— In this study we describe a new species, Epidendrum itacolomiensis, from the historically well collected region of the Itacolomi peak, Minas Gerais, Brazil. We compare the new species with taxa belonging to the E. proligerum complex. The
new species has some of the smallest flowers of the complex and is similar to E. bothryanthum and E. parahybunense, but it is easily distinguished from them by the erect stems, the absence of a distinct ventral vesicle in the pedicellate ovary formed by an inflated cuniculus,
and pale pink flowers. It also differs from E. bothryanthum by the entire lip. We also provide an illustration, photographs, and an identification key for the species complex. This study highlights that even extensively collected areas in the Brazilian Atlantic Forest may hide new orchid
taxa.
