OBJECTIVES

Children in immigrant families comprise ∼25% of US children and live in families with high levels of poverty and food insecurity. Studies suggest a decline in public benefit enrollment among children in immigrant families. We aimed to explore perspectives on barriers and facilitators in accessing care among immigrant caregivers of hospitalized children.

METHODS

With a general qualitative descriptive design, we developed a semistructured interview guide using an iterative process informed by literature and content expertise. Using purposive sampling, we recruited immigrant caregivers of hospitalized children in March 2020 and conducted interviews in English or Spanish. Interviews were recorded, transcribed, and translated to English. Three authors coded transcripts using Dedoose and identified themes via thematic analysis.

RESULTS

Analysis of 12 caregiver interviews revealed barriers and facilitators in accessing healthcare and public benefit use. Barriers included healthcare system barriers, immigration-related fear, and racism and discrimination. Within healthcare system barriers, subthemes included language barriers, cost, complexity of resource application, and lack of guidance on available benefits. Within immigration-related fear, subthemes included fear of familial separation, fear of deportation, fear that benefit use affects immigration status, and provider distrust. Healthcare system facilitators of resource use included recruiting diverse workforces, utilizing language interpretation, guidance on benefit enrollment, legal services, and mental health services. Participants also recommended hospital partnership with trusted information sources, including media stations and low-cost clinics.

CONCLUSIONS

Immigrant caregivers of hospitalized children identified barriers and facilitators in access to care. Further research is needed to assess the efficacy of caregiver-suggested interventions.
THE APPLICATION OF THE EXTENDED CELLS METHOD TO SIMULATE THE FLOW OF COMBUSTION GASES IN THE LPRE CHAMBER
Authors: Дубровський І.Д. , Бучарський В.Л.
Published: November 2023

Abstract. The numerical modeling of the process of two-dimensional axisymmetric flow of combustion gases in the chamber of a liquid rocket engine is considered in this study. In general, when solving such problems, meshes are used which lines coincide with the boundaries of the computational domain. However, an alternative solution is proposed here, which is to apply the extended cells method. It allows using rectangular Cartesian grids, which lines do not coincide with the boundaries of the computational domain, without reducing the stability of the numerical solution due to the fractional finite volumes. This also simplifies the setting of boundary conditions in such volumes. The advantage of the proposed approach over the generally accepted one is the absence of the global geometric transformations during the entire modelling process, which leads to a reduction in its duration. To perform the numerical modelling, an inviscid ideal compressible gas of constant chemical composition was chosen as a basic model of a continuum. It is described by a system of the unsteady Euler equations in integral form, which was closed by the Mendeleev-Clapeyron equation of state. For the numerical solution of this system, the finite volume method was used with the reconstruction of the flow parameters by the WENO algorithm of the third order of accuracy. The solution of the Riemann problem was carried out using the Lax-Friedrichs relations. Time integration of the system of equations was performed using the explicit Runge-Kutta method of the third order of accuracy. All calculations were carried out on a uniform rectangular Cartesian mesh, which lines did not coincide with the boundaries of the computational domain. The results were compared with the solution of the same problem using the ANSYS Fluent on an unstructured mesh coinciding with the boundaries of the computational domain. The value of the relative error obtained as a result of comparing both solutions did not exceed 0.05.

Анотація. Розвиток і вдосконалення засобів адитивного виробництва та виготовлення виробів знаходить застосування і у авіаційній та ракетно-космічній техніці. З появою нових вимог до деталей та виробів розроблюються нові технології синтезу деталей, та покращуються вже існуючі. Наприклад, спостерігаються такі тенденції, як: використання більш високоміцних полімерних матеріалів, автоматизація процесів викладання волокнистих та стрічкових матеріалів при формуванні виробів та покращення методів контролю якості, у тому числі і безпосередньо в процесі формування. Також, одним із видів вдосконалення існуючих і добре відомих технологій FDM/FFF 3d-друку для покращення властивостей деталей – армування композиційними волокнами. Серед більшості видів армування найбільш дієвим та перспективним є армування неперервними волокнами, а саме – армування товпрегом та використання окремого сопла для додавання армуючого волокна, оскільки саме ці типи дозволяють отримати вироби для застосуванні в РКЛА з контрольованими характеристиками. Але є проблема невизначених параметрів речовин, що додають до армуючих волокон у процесі їх виготовлення, що вносить невідомі змінні у дослідження параметрів отриманих деталей. Мета даної роботи – розробка моделі вузла подачі чистого волокна без додавань, відпрацювання прийомів та особливостей поведінки волокна у подавальних трактах. Було проаналізовано літературу та новини про 3d-принтери, що дозволяють армувати деталі, створена реферансна модель вузла подачі, проведені випробування на вуглецевому та базальтовому волокні. За результатами була створена вдосконалена модель вузла подачі, проведені випробування, визначені оптимальні для заданих вихідних даних параметри деяких деталей та частин вузла подачі. Визначені особливості поведінки чистого, необробленого волокна при подаванні, отримані дані для розробки та проектування вузла подачі волокна, що буде безпосередньо встановлюватись на 3d-принтер. Також, було досліджено можливість виготовлення деталей для подібних механізмів подачі за допомогою FDM/FFF 3d-друку. Були підібрані параметри деталей, які можливо надійно виготовляти методами 3d-друку без негативного впливу на роботоздатність вузла подачі.

Анотація. Застосування адитивних технологій для виробництва деталей в авіа- та ракетобудуванні з кожним роком набуває все більшого поширення, оскільки даний метод має ряд значних переваг в порівнянні з традиційними технологіями такими як штампування, лиття та механічна обробка та розглядається як альтернативний метод виготовлення. Однак адитивні технології нажаль мають вагомий і серйозний недолік, а саме отримання необхідної заданої шорсткості та якості поверхні виробів незалежно від їх просторового розташування. Застосування даного методу дозволяє виготовляти різні деталі ракетно-космічної техніки насамперед робочі колеса турбін з лопатками закритого типу на одному типі обладнання за значно коротший час. Однак не дивлячись на значні переваги адитивних технологій, актуальною залишається проблема шорсткості та забезпечення кінцевої якості поверхні незалежно від просторового розташування елементів деталі. Причиною цьому є обмежений доступ  традиційного ріжучого інструменту типу фрез чи шліфувальних головок. Перспективним методом обробки робочих поверхонь лопаток турбін закритого типу є абразивно-струменева обробка (бластінг). Правильний вибір технологічних режимів  може гарантувати  забезпечення результатів струменевої обробки. Однак необхідність врахування значної кількості вхідних даних, а саме параметрів обладнання, абразивного струменя, фізико-механічних властивостей матеріалу та форми оброблюваних поверхонь виробів, а також відсутність чітких рекомендацій та технологічних даних суттєво ускладнюють процес.

Метою завданням є моделювання струменевої обробки лопаток моноколіс закритого типу з використанням програмної системи аналізу кінцевих елементів ANSYS CFX. У даній статті наведені результати чисельного моделювання обробки поверхонь закритих лопаток турбін та виявлення технологічних факторів, що впливають на шорсткість та якість поверхні середовищі стисненого повітря на зразках виготовлених зі сплаву Inconel 718.

Отримані результати будуть використані при розробці реального технологічного процесу обробки проточних частин лопаток закритого типу та подальше впровадження у виробництво.

Published: November 2023

Background

Acute campylobacteriosis caused by oral infections with the enteropathogen Campylobacter jejuni represent serious threats to global human health. Since novel treatment options with safe and antibiotics-independent compounds would be highly appreciable, we here investigated the anti-bacterial and disease-alleviating effects of carvacrol, butyrate, ellagic acid, and 2′-fucosyl-lactose in acute murine campylobacteriosis. To address this, secondary abiotic IL-10−/− mice were perorally infected with C. jejuni and treated with either compound alone or all four in combination via the drinking water starting two days post-infection.

Results

On day 6, the duodenal pathogen loads were lower in mice of the combination versus the vehicle treatment cohort. Importantly, mice treated with carvacrol and the combination presented with less distinct diarrheal symptoms, colonic histopathology, epithelial cell apoptosis, and immune cell responses when compared to vehicle counterparts on day 6 post-infection. Furthermore, the combination treatment did not only diminish colonic IFN-γ, TNF-α, and IL-6 secretion in C. jejuni infected mice, but also dampened extra-intestinal and even systemic pro-inflammatory cytokine concentrations to basal levels as measured in liver, kidneys, lungs, and serum samples.

Conclusions

Our preclinical placebo-controlled intervention trial provides evidence that the combined oral application of carvacrol, butyrate, ellagic acid, and 2′-fucosyl-lactose alleviates acute campylobacteriosis in the vertebrate host.
Effective Combination of Nigella sativa and Trigonella foenum-graecum Seed Extract on Wound Healing in Diabetic Mice
Authors: Susilowati Retno , Rohmanningrum Ulfa Maynisa
Published: November 2023

High levels of free radicals in diabetic wounds often cause chronic inflammation. Nigella sativa and Trigonella foenum-graecum seed extracts are rich in antioxidants and have anti-inflammatory effects. Trigonella foenum-graecum seed extracts can also accelerate the reepithelialization process in wound healing. This study aimed to determine the combination of ethanol extract of Nigella sativa and Trigonella foenum-graecum seeds on wound length and the number of neutrophils, macrophages, fibroblasts, and collagen density in the incision wound of diabetic mice induced by streptozotocin. T. This study used three types of controls, namely Normal (Normal mice,  HPMC 3%),  DM (Diabetic mice, HPMC 3%), and Iodine (Diabetic mice, Povidone Iodine 10%). Topical treatment with 70% ethanol extract ointment combined with Nigella sativa and Trigonella foenum-graecum in various variations, namely N (20%:0%), T (0%:10%), NT (10%:5%), Observations of the wound healing process were carried out on 3rd, 7th and 14th day. Data were analyzed using the One Way ANOVA and Duncan Multiple Range Test. The study's results by observing the morphology of the wound length on day 7th day showed that the combination treatment of extracts of Nigella sativa and Trigonella foenum-graecum resulted in the shortest wound, which was significantly different from the wound in untreated diabetic mice. In addition, diabetic wounds without treatment showed infection, and on the contrary, the infection did not occur in wounds treated with a combination of extracts of Nigella sativa and Trigonella foenum-graecum. The results of wound histology observations showed that the combination treatment of extracts of Nigella sativa and Trigonella foenum-graecum showed a decrease in inflammation which was indicated by a significant decrease in the number of neutrophil cells, macrophages, and accelerated reepithelialization of wound healing as indicated by a significant increase in the number of fibroblasts and collagen density since the third day of treatment.

A pandemia de SARS-CoV-2 (COVID-19) ocasionou mudanças no processo de ensino. As instituições de ensino superior adaptaram-se e passaram a figurar como divulgadores científicos no YouTube. A temática de Ciências Exatas e da Terra foi a segunda mais abordada nos conteúdos produzidos. Através do projeto unificado Grupo de Estudos em Geociências (GEOS) e seu canal no YouTube, a Universidade Federal de Pelotas (UFPEL) atuou na divulgação de temas geocientíficos, utilizando metodologias lúdicas. Porém, com o retorno às atividades presenciais, é possível que as métricas dos vídeos publicados na internet durante a pandemia reflitam preferências do público, de modo a orientar atividades de extensão futuras? Para responder à questão, este trabalho analisou as métricas de 10 vídeos publicados pelo GEOS-UFPEL, com dados obtidos no YouTube Studio do canal do projeto. Os resultados demonstram que as datas de publicação não influenciaram nos números de visualizações do canal e que os vídeos mais vistos estão associados aos tópicos mais básicos de geologia, como “As Camadas da Terra” e “Vulcões”. A maior parte do tráfego do canal é oriunda de vídeos sugeridos, o que pode indicar uma rede de divulgação geocientífica. Os dispositivos mais utilizados para acesso foram celulares e computadores. Conclui-se que as métricas do canal serão úteis para o planejamento de ações futuras e, em uma rede de divulgação científica, o conteúdo audiovisual do GEOS é um Recurso Educacional Aberto e cumpre o papel de auxiliar docentes na abordagem de temas científicos em sala de aula.

Edukacja w trosce o „efekt pogranicza” międzykulturowego (panorama tropów i profili humanistycznych w retrospekcji)
Authors:   Akademia Pomorska w Słupsku, Witkowski Lech
Published: November 2023

The text comprises a normative concern for the educational “borderland effect”. Within the hermeneutical circle, there are: (1) M. Bakhtin’s semiotics of culture and the idea of “borderland effect” as a developmental mechanism increasing the polyphonic dynamics and value of the Other; (2) an analogy to the “decentration” mechanism according to J. Piaget and J. Habermas and the idea of dialogue inspired by H.–G. Gadamer; (3) M. Buber’s idea of two types of faith and difficulties of ecumenism; (4) H. Hesse’s idea of spiritual awakening and inner transformation; (5) the types of adaptation to the complexity of interactions and the vision of identity as “the third value”, following D. Mostwin’s analysis of the Polish emigration in the USA; (6) difficulties with the borderland effect in creating Polish schools in Latvia in D. Urlińska’s experiment; (7) F. Znaniecki’s concern to eliminate intercultural antagonisms; (8) normative strategies towards tradition, freedom and change, as diversified attitudes towards differences and the “borderland effect”; (9) the coupling of interests of the disabled in integrated schools as a borderland problem; (10) the concept of the “borderland order” as a mechanism of sustainability and oscillation in dual integration with shifting the local dominants; (11) B. Skarga’s cultural attitude open to irony, withdrawing cultural persuasiveness. The “borderland effect” brings change of the cultural “meta-pattern” for education. The analyses conducted by M. Mead and F. Znaniecki imply the intercultural education open to differences between the young, against the pressure of antagonisms of the world of adult people.
Perspektywa intersekcjonalna w pedagogice międzykulturowej

Published: November 2023

A meeting with the Other is related to the attitude of interest, dialogue, cooperation and understanding. However, negative reactions to otherness may give rise to different attitudes as well. These include discrimination and exclusion. In this article, the problem of multiple discrimination is addressed and intersectionality is presented as both an important method in intercultural research and an idea worth raising and developing in the practice of intercultural education. Multiple discrimination pertains to people who experience two or more forms of oppression at the same time (due to gender and disability; due to disability and residence place; due to ethnic origin, gender and place of residence, etc.). Intersectionality introduces a new quality to intercultural studies. As a research paradigm, it enables a critical analysis of these areas of exclusion and discrimination which have so far been shown mainly from the perspective of the needs and views of majority groups. Intersectional analysis can also become useful in educational practice: in preparing individualized assistance programs for people affected by discrimination, as well as in creating preventive projects to keep stigmatization and discrimination away.

Representatives of every minority want their rights to be respected in the state in which they live and of which they are citizens. The problems related to education for national minorities are among the most complicated and arguable. Political controversies and disputes in magazine columns do not always translate into good relations in the culturally diverse environment. The text is aimed to present the situation related to the conflict in one of the schools in Lithuania, which began (as a kind of prelude) at the end of 2021 and developed in 2022. Our assumption was to analyze the described situation from three perspectives presented in: the Polish press in the context of some actions taken by the government and their effects, as well as the way of describing them; an analogical presentation of the Lithuanian perspective and the stakeholders themselves (including the headmaster of the school where the described situation took place). For a better understanding of the context of the described analyses, the text begins with a brief description of the current legal status, the educational network and its scope.

ON THE QUESTION OF THE VALIDITY OF THE USE OF BAIL BY THE INVESTIGATING JUDGE AS A PREVENTIVE MEASURE
Authors:   Kyrgyz National University named after J. Balasagyn, Kalygulova Alima
Published: November 2023

The article is devoted to the issue of the validity of the use of bail by the investigating judge as a preventive measure. The relevance of the study is due to the fact that in the law enforcement practice of criminal proceedings, when deciding on the application of a preventive measure, detention is most often used and, in a rare case, other measures are applied. Bail as a measure of restraint and specific instructions in the Criminal Procedure Code of the Kyrgyz Republic, as well as the grounds for which it is necessary to apply this measure of restraint, could make it possible to resolve a large number of issues such as overcrowding in places of detention, preventing arbitrariness when deciding on the measure suppression, elimination of corruption and would give an opportunity to observe the principle of the presumption of innocence.

Sistemi di assistenza ventricolare, ponte e destinazione. Mai come in questo caso è indispensabile la continuità ospedale territorio
Authors: Perna Enrico , Verde Alessandro , Garascia Andrea
Published: November 2023

L’insufficienza cardiaca è una sindrome clinica complessa, ancora gravata da una prognosi severa, nonostante i progressi della terapia. Le fasi più avanzate dell’insufficienza cardiaca presentano, inoltre, aspetti gestionali di particolare complessità in particolare per i pazienti candidabili a terapia sostitutiva cardiaca. Le assistenze ventricolari sinistre (LVAD) sono ormai un’opzione terapeutica consolidata per i pazienti in scompenso cardiaco avanzato. Nonostante persistano potenziali complicanze la tecnologia ha permesso di raggiungere livelli di sopravvivenza pressoché sovrapponibili al trapianto cardiaco nei primi 2-3 anni post-impianto. La continuità territorio-ospedale è fondamentale per la selezione del paziente e per la realizzazione di una rete di gestione condivisa dopo la dimissione. La continuità va intesa come condivisione di conoscenze per scongiurare il late referral pre- e post-impianto. In Italia la sensibilizzazione al programma VAD è fortemente condizionata dal limitato numero di impianti, dall’assenza di un registro nazionale e di un controllo da parte di un ente centrale.
Risk-Based Community Screening for the Evaluation of Atrial Fibrillation Trial (R-BEAT): a randomised controlled crossover trial protocol v1
Authors: P Murphy Robert
Published: November 2023

Background: Undiagnosed atrial fibrillation is a major care-gap in stroke prevention. We describe a protocol for a randomised cross-over controlled trial evaluating a community-based approach to detecting covert atrial fibrillation, comparing routine external loop recorder monitoring with routine pulse screening, in a primary care population. Methods: We are undertaking a randomised controlled, cross-over multi-center trial in general practice comparing routine external loop recorder (ELR) cardiac monitoring (R-Test) for 1 week with usual care (pulse screening and completion of cardiac rhythm assessment if pulse is irregular). The target population is patients aged ≥55 years with CHA2DS2VASc > 2 who do not have a contraindication for oral anticoagulation, as determined by the General Practitioner. The trial is being conducted in 10 general practice sites in the West of Ireland. Participants are randomly assigned by computer generated block randomisation with variable block size to the immediate or delayed external loop recorder group assigning individual participants in a 1:1 ratio. The trial is conducted in an open-label fashion, with blinded outcome assessment. The trial also evaluates the role of serial participant self-pulse screening for detection/exclusion of atrial fibrillation. The primary outcome measure is newlydetected, and centrally confirmed cases of atrial fibrillation/flutter greater than two minutes in duration. Recruitment is ongoing. Discussion: The R-BEAT study will determine whether a 1-week ELR is associated with a greater detection rate of atrial fibrillation versus pulse screening in patients attending General Practice with a CHA2DS2VASc score of greater than 2.

Asymptotic differentiation of signals in the trajectory tracking control of a differentially flat nonlinear magnetic suspension system
Authors: Beltrán Carbajal Francisco , Favela Contreras Antonio , Valderrábano González Antonio , Silva Navarro Gerardo
Published: November 2023

This paper deals with the problem of time-varying desired position reference trajectory tracking tasks for an object in a differentially flat nonlinear magnetic levitation system using position measurements only. A novel scheme for signal differentiation is proposed for asymptotic estimation of velocity and acceleration. This differentiator can be utilized in many control applications of practical engineering systems where the differentiation of any signal is required. The differentiation of signals is combined with a differential flatness-based controller for asymptotic tracking of reference trajectories. Simulation results are provided to show the efficient performance of the proposed differentiator-control scheme. Two issues for reference trajectory tracking tasks are performed. The first one considers the rest-to-rest position transfer problem of the object from a nominal position to another, while the second one focuses on the sinusoidal position trajectory tracking problem.
bit more on the ability of adaptation of speech signals
Authors: Ballesteros L. Dora M. , Moreno A. Juan M.
Published: November 2023

Some traditional digital signal processing techniques encompass enhancement, filtering, coding, compression, detection and recognition. Recently, it has been presented a new hypothesis of signal processing known as the ability of adaptation of speech signals: an original speech signal may sound similar to a target speech signal if a relocation process of its wavelet coefficients is applied. This hypothesis is true under some conditions theoretically defined. In this paper we present the basic idea behind the hypothesis of adaptation and moreover, we test the hypothesis within four cases: speech signals with the same gender and language, speech signals with the same gender but different language, speech signals with the same language but different gender, and speech signals with different gender and language. It is found that the hypothesis is true if the requirements are satisfied, even if the gender or the language of the original and target signals are not the same.
Performance of multivariable traffic model that allows estimating Throughput mean values
Authors: Hernández Cesar , Salgado C. , Salcedo O.
Published: November 2023

The present paper is aimed at developing a multi-variable traffic model of a Wi-Fi data network that allows estimating throughput mean values. In order to construct the model, data corresponding to an 8-host wireless adhoc network were collected using a software package called WireShark; the network was specially designed for modeling purposes. Subsequently, the most convenient multi-variable models were estimated according to the traffic features extracted from the collected data. Results were the evaluated using a software package called STATA, leading to the establishment of significant explanatory variables for the model and its performance levels. For our Wi-Fi network, results show that the analyzed traffic exhibits selfsimilarity features. Additionally, model coefficients and their corresponding significance levels are shown in various Tables. Finally, an explanatory multivariable model consisting of four variables was produced on the basis of ordinary least-squares methodologies (with a per-cent error of 22.16). The findings suggest that the multi-variable traffic model produced in this study allows a reliable analysis of throughput mean values; however, the model is limited when predicting traffic values for data outside the selected estimation set.
Novel Exponential Function Based Model for an Uniaxial Magnetic Levitation System
Authors: Martínez Juan E. , Bedoya Carol L.
Published: November 2023

In this paper a new dynamic model for a uniaxial magnetic levitation system is developed from magnetostatic principles, which we have not found in literature. The system has two coils which are the actuators to control the position of two magnets that need to slide on a vertical axis; this configuration is used in motors with magnetic suspension and generally in any system with active magnetic bearings. Based on the Amperian model and the Biot – Savart law for this system, it was established by means of numerical calculations, the force and distance relationships between the actuators and magnets and between magnets. Once the mentioned relations were numerically determined, then exponential curve fitting was done to them, in order to obtain the nonlinear dynamic model of the magnetic suspension system. This article further presents a linearized model generated from the model previously obtained, showing that it correctly represents the system dynamics near the point of operation.
Methodology to obtain the linear range of a transistor as a control element in a DC current source
Authors: Velilla Esteban , Muñoz John Ever , Osorno Yurany A. , Londoño Nelson
Published: November 2023

This paper presents a methodology to develop direct current sources using BJT transistors on the linear region (active region). This region depends on the saturation voltage, maximum power and polarization voltage of the element; from these parameters it is obtained the load resistance range that ensures a constant current. The methodology is used to develop a DC current source prototype of 2A and the range of the load resistance is defined by the transistor characteristics. The temperature and power constrains are taking into account.

Традиционно определение межвидовых гибридов дикорастущих растений, как и предполагаемых родительских видов, основывается на их морфологических признаках. Проявления межвидовой гибридизации и интрогрессии на морфологическом уровне многообразны (гибриды не всегда обладают промежуточными признаками родительских таксонов, нередко сходны с одним из родителей) и их интерпретация систематиками неоднозначна. В связи с этим ведутся активные попытки идентификации гибридов с помощью молекулярных маркеров. Использование молекулярных маркеров (последовательностей молекул ДНК) для медицинской диагностики патогенных микроорганизмов и вирусов, а также определения видов растений и животных в биологии позволяет не только установить штамм или вид, но и значительно ускоряет сам процесс диагностики/идентификации. В биологии такие методы идентификации видов получили название ДНК-баркодинг или метабаркодинг. Целью исследования является разработка молекулярно-генетической системы интегративной идентификации гибридов и видов на примере видов рода Carex L. (осока) секции Ceratocystis. Carex L. – один из крупнейших и широко распространенных родов цветковых растений, насчитывающий около 2000 видов, из которых не менее 350 встречается на территории нашей страны [1,2]. Они участвуют в формировании растительного покрова, выступают эдификаторами или доминирующими видами в различных растительных сообществах. Явление гибридизации, образование фертильных гибридов, встречается в нескольких секциях: в 4 из подрода Carex – Phacocystis, Ceratocystis, Glareosae, Vesicariae и в 3 из подрода Vignea: Heleonastes, Vulpinae, Heleoglochin [3,4]. На Северо-Западе европейской части России встречается 8 видов из модельной группы Ceratocystis: C. flava L., C. hostiana DC, C. aggr. viridula (C. lepidocarpa Tausch, C. jemtlandica (Palmgr.) Palmgr., C. demissa Hornem., C. serotina Mérat, C. bergrothii Palmgr., C. scandinavica Dav.), что исчерпывает таксономическое разнообразие группы на территории всей России [1]. На Северо-Западе страны в пределах секции отмечали следующие гибриды/нотовиды: C. ruedtii (=C. × pieperana) (C. flava × C. lepidocarpa), C. × apeliana (C. hostiana × C. serotina), C. × schatzii (C. lepidocarpa × C. serotina) C. × subviridula (C. flava × C. serotina). Баркодирование растений из этой секции затруднено в связи с активными процессами гибридизации и интрогрессии. Нами были секвенированы последовательности нескольких генетических маркеров: ITS, matK, rpS16, растений собранных на территории Северо-Запада европейской части России из коллекций гербариев LE (БИН РАН) и LECB (каф. ботаники, СПбГУ), а также проанализированы последовательности из NCBI, после чего проведено сопоставление топологий деревьев, полученных с использованием пластидных и ядерных генов. Исследование выполнено при поддержке РНФ №22-24-01117.
Synodality in Orthodox, Protestant and Catholic theological reflection
Authors: Bujak Janusz
Published: November 2023

Celem artykułu jest ukazanie wybranych kwestii z zakresu teologicznej refleksji nad znaczeniem synodów w teologii prawosławnej, luterańskiej i katolickiej.
Teologowie prawosławni uzasadniają synodalny wymiar Kościoła nauczaniem Chrystusa, praktyką okresu apostolskiego i rozwojem synodalności w pierwszym tysiącleciu Kościoła. W Kościołach prawosławnych synodalność ma charakter episkopocentryczny i wyraża się na poziomie Kościoła lokalnego, z biskupem na czele oraz na poziomie regionalnym. Po zerwaniu jedności z Kościołem rzymskim w roku 1054 Kościoły prawosławne nie odbyły żadnego soboru o wymiarze ekumenicznym. To, co jest charakterystyczne dla wschodniej teologii synodów i soborów, to przekonanie, że ich decyzje nie są obowiązujące ex sese, ale uzyskują swoją ważność po recepcji przez wiernych.
We Wspólnotach kościelnych wywodzących się z reformacji mamy różne formy organizacji synodalnej. W luteranizmie niemieckim do XX wieku obowiązywał model Kościoła państwowego, w którym sprawami Kościoła zarządzali władcy świeccy biskupów. Akceptacja takiej formy zarządzania Kościołem wynikała z wielu czynników, m.in. z teologii Marcina Lutra o powszechnym kapłaństwie i braku biskupów, których zastąpili właśnie książęta. W XIX, a zwłaszcza w XX wieku Kościoły luterańskie w Niemczech wypracowały struktury synodalne, w których główną rolę odgrywają świeccy. Decyzje podejmowane na synodach nie są uznawane za nieomylne, dlatego mogą podlegać zmianom. Również Wspólnoty luterańskie nie znają ekumenicznego wymiaru synodów.
W Kościele rzymskokatolickim, podobnie jak w Kościołach prawosławnych, za źródło synodalności uznaje się praktykę Kościoła apostolskiego, zwłaszcza Sobór Apostolski opisany w Dziejach Apostolskich w rozdziale piętnastym, i okres pierwszego tysiąclecia Kościoła, w którym rozwinęły się struktury synodalne i soborowe. W Kościele rzymskokatolickim mamy dwa poziomy synodalności: pierwszy dotyczy prymatu papieża i kolegium biskupów będących z nim w jedności, drugi natomiast opiera się na udziale wszystkich ochrzczonych w życiu Kościoła, który polega na ich funkcji doradczej. Charakterystyczne dla Kościoła rzymskokatolickiego jest zachowanie wszystkich trzech poziomów synodalności: lokalnego, regionalnego i powszechnego, dzięki papieżowi, który zwołuje sobory. W Kościele rzymskokatolickim decyzje soborowe nie wymagają zatwierdzenia przez wiernych świeckich, ale uznawane są obowiązujące po przyjęciu ich przez zgromadzenie soborowe i papieża. Obecnie trwa dyskusja nad większym włączeniem w wiernych świeckich w podejmowanie decyzji dotyczących życia Kościoła.
Psychological measurement of religiosity of students of a Poznan (Poznań) non-public school and a youth parish community during the Covid-19 pandemic period
Authors: Kozak Igor
Published: November 2023

Tematem artykułu jest religijność młodzieży z Archidiecezji Poznańskiej. Wykorzystano w nim badania sondażowe, przeprowadzone w ósmych klasach społecznej szkoły podstawowej oraz pośród członków grupy młodzieżowej działającej przy parafii św. Jana XXIII w Komornikach. Młodzież, głównie dziewczęta, została przebadana trzema testami mierzącymi religijność w aspektach: emocji wobec Boga, personalnej relacji do Boga oraz spójności przekonań religijnych adolescentów. W części teoretycznej artykułu omówione zostały zagadnienia specyfiki adolescencji, w tym rozwoju religijności na tym etapie rozwojowym.
Más allá del diagnóstico de leucemia congénita neonatal

La leucemia congénita neonatal se presenta en los primeros 30 días de vida y es una enfermedad muy poco frecuente en este grupo etario, pero sí de mayor presencia entre los pacientes con síndrome de Down. Su etiología es principalmente genética, pero también se asocia con el consumo de alcohol, la marihuana y el tabaquismo. Se debe hacer diagnóstico diferencial con el desorden mieloproliferativo transitorio, que es una entidad benigna y se resuelve de forma espontánea. Se presenta un caso clínico de un paciente recién nacido a término, de 16 días, que inicialmente presenta sintomatología sugestiva de enterocolitis necrotizante. Sin embargo, al ingresar a unidad neonatal, se evidencia abdomen muy distendido con hepatoesplenomegalia severa con hemograma con hiperleucocitosis severa, anemia y trombocitopenia asociado a blastos del 100 % y paraclínicos de extensión, sugestivo de síndrome de lisis tumoral, por lo que se inicia manejo con hiperhidratación, alopurinol y rasburicasa, sin mejoría. Por esta razón se adiciona citarabina. La citometría de flujo reporta patrón megaloblástico, es decir, un patrón de leucemia mieloide. Requiere hospitalización por mes y medio; luego de este tiempo pueden presentarse complicaciones esperadas. No obstante, se consideró que el recién nacido cursó con trastorno mieloide transitorio, en razón a evolución clínica satisfactoria, con disminución de sintomatología y de leucocitosis severa.

Published: November 2023

La proteinosis alveolar pulmonar (PAP) es una enfermedad poco frecuente que compromete el intersticio pulmonar de forma difusa, con acumulo de surfactante pulmonar y obstrucción alveolar, que puede resultar en insuficiencia respiratoria. A continuación, se describe el caso de un paciente masculino de 32 años de edad, residente en Bogotá, Colombia, que ingresa por presentar deterioro de clase funcional progresiva con requerimiento de oxígeno suplementario, hallazgos al examen físico de ingreso consistentes con estertores finos bibasales junto con acropaquias. Se realiza tomografía computarizada (TAC) de tórax y se evidencia “patrón empedrado” junto a estudio broncoscópico con citología de lavado broncoalveolar con abundante contenido proteico en compañía de macrófagos con tinción de PAS ( ácido p eryódico d e S chiff) p ositivo, y a nticuerpos anti-GM-CSF positivos. Por esta razón se efectúa el diagnóstico de proteinosis alveolar y posteriormente se procede a realizar lavado pulmonar total. El paciente presenta mejoría de la oxigenación y, por tanto, se da egreso. Dada la escasez de estudios en Colombia sobre PAP, se decide realizar la descripción de un caso y revisar la literatura.

El asma es una enfermedad que continúa en aumento y es causa de incapacidades. Su origen es multifactorial lo cual complica su estudio.Los gastos monetarios que se generan por su manejo ascienden a billones de dólares; esta enfermedad no es exclusiva de la infancia, ya que los jóvenes,muchas veces,al estar expuestos a sustancias dentro de su hogar pueden desarrollarla lo que deriva en deterioro de la calidad de vida.En el presente estudio se encuestó a 361jóvenes universitarios de tres programas profesionales en una Institución de Educación Superior en Barranquilla con el objetivo de determinar cuáles factores podrían desencadenarles la enfermedad. En el análisisvestadístico se realizaron prueba de Chi-cuadrado, valor p y Odds ratio. En los resultados se encontró  que los factores que probablemente podrían predisponer a la aparición del asma son: empleo de detergentes, emociones fuertes y contacto con humo.

Authors: Algahtani Abdulhadi , Ashqar Alaa , Al Rabie Abdulkarim , Ahmed Jehad
Published: November 2023

Introduction: The coronal subluxation of C2-C3 (lateral leisthesis or non-hangman fracture) is extremely rare and difficult to manage. In this paper, we report a case of a 21-year-old male who came to the ER after a motor vehicle accident (MVA) with C2-C3 lateral leisthesis and, surprisingly, mild neurological symptoms.
Method: This systematic review was conducted following the recommendations of the preferred reporting items for systematic reviews and meta‐analyses (PRISMA) checklist. On January 1, 2022, a comprehensive electronic search was conducted through Scopus, PubMed, and Web of Science databases to retrieve original studies.
Results: Seven articles were found reporting on non-hangman traumatic C2/C3 subluxation, with only two cases reporting coronal subluxation or lateral listhesis of C2 over C3. The first case was reported by Rajasekaran et al. Singh reported the second case. Both cases were unilateral facet dislocations with no radiological evidence of intervertebral disc disruption or herniation. We will report the third case in the literature of a non-hangman C2/C3 coronal dislocation. The patient underwent intraoperative manual traction under continuous neurophysiology monitoring. After the satisfactory reduction, fixation was carried out using lateral mass and pars screws from C1 to C3. Postoperatively, the patient recovered well, showed no signs of motor impairment during examination, and was discharged on the fifth day.
Conclusion The impact of cervical spine injury is tremendous at every level. Management of cervical spine dislocation injury is full of controversies. The C2/C3 traumatic coronal translation with no disc involvement and unilateral facet dislocation may have a better outcome.
