Тема Чорного моря в літературних інтрепретаціях Євгена Маланюка
Authors: Баган Олег
Published: December 2024

The article interprets artistic images on the theme of the Black Sea in the work of the iconic Ukrainian poet and thinker of the interwar period – Yevhen Malanyuk. Emphasis is placed on the expressiveness of the artistic thinking of Malanyuk, who managed to create bright and multifaceted images-symbols and images-concepts regarding the mental and civilizational attraction of the Ukrainian ethnic group to the Black Sea. It is traced how the author substantiated his poetic visions with deep theoretical reflections in historiosophical and cultural essay writing. The central idea of the writer: the Black Sea was and is an important geopolitical and geocultural frontier for the Ukrainian ethnic group and its state. It is explained why Malanyuk believed that the Hellenistic and Scythian-Sarmatian archetypes from Ukrainian ethnogenesis determined the peculiarities of the Ukrainian psychotype.
WSN intrusion detection method using improved spatiotemporal ResNet and GAN
Authors: Yang Jing
Published: December 2024

A network intrusion detection method that integrates improved spatiotemporal residual network and generative adversarial network (GAN) in a big data environment is proposed to address the issues of poor feature extraction and significant impact from data imbalance in most existing intrusion detection methods. First, GANs are used for wireless sensor network data resampling to generate new sample sets, thereby overcoming the impact of data imbalance. Then, an improved spatiotemporal residual network model is designed, in which the spatial and temporal features of the data are extracted and fused through multi-scale one-dimensional convolution modules and gated loop unit modules, and identity maps are added based on the idea of residual networks to avoid network degradation and other issues. Finally, the resampled samples are input into the improved spatiotemporal residual network model to output the intrusion detection results of the network. Based on the NSL-KDD, UNSW-NB15, and CICIDS2017 datasets, experimental analysis is conducted on the proposed method. The results showed that its accuracy on the three datasets is 99.62, 83.98, and 99.86%, respectively, which are superior to other comparative methods.

Authors: Zheng Feng-Xia , Li Hong-Xu
Published: December 2024

In this article, a family of delay differential equations with pseudo compact almost automorphic coefficients is considered. By introducing a concept of Bi-pseudo compact almost automorphic functions and establishing the properties of these functions, and using Halanay’s inequality and Banach fixed point theorem, some results on the existence, uniqueness and global exponential stability of pseudo compact automorphic solutions of the equations are obtained. Our results extend some recent works. Moreover, an example is given to illustrate the validity of our results.
Harbingers of sepsis misdiagnosis among pediatric emergency department patients
Authors: Sawicki Jonathan G. , Graham Jessica , Larsen Gitte , Workman Jennifer K.
Published: December 2024

Objectives

To identify clinical presentations that acted as harbingers for future sepsis hospitalizations in pediatric patients evaluated in the emergency department (ED) using the Symptom Disease Pair Analysis of Diagnostic Error (SPADE) methodology.

Methods

We identified patients in the Pediatric Health Information Systems (PHIS) database admitted for sepsis between January 1, 2004 and December 31, 2023 and limited the study cohort to those patients who had an ED treat-and-release visit in the 30 days prior to admission. Using the look-back approach of the SPADE methodology, we identified the most common clinical presentations at the initial ED visit and used an observed to expected (O:E) analysis to determine which presentations were overrepresented. We then employed a graphical, temporal analysis with a comparison group to identify which overrepresented presentations most likely represented harbingers for future sepsis hospitalization.

Results

We identified 184,157 inpatient admissions for sepsis, of which 15,331 hospitalizations (8.3 %) were preceded by a treat-and-release ED visit in the prior 30 days. Based on the O:E and temporal analyses, the presentations of fever and dehydration were both overrepresented in the study cohort and temporally clustered close to sepsis hospitalization. ED treat-and-release visits for fever or dehydration preceded 1.2 % of all sepsis admissions.

Conclusions

In pediatric patients presenting to the ED, fever and dehydration may represent harbingers for future sepsis hospitalization. The SPADE methodology could be applied to the PHIS database to develop diagnostic performance measures across a wide range of pediatric hospitals.

Published: December 2024

Objectives

Validation and performance assessment of novel ESR analyzer is required before implementation. The objective of this study was to assess the correlation between three ESR measurement methods. Full validation and performance assessment of an alternate method (TEST1) were also evaluated.

Methods

Three-way correlation assessment for the Westergren (WG), modified Westregren (Mixrate), and alternate (TEST1) methods were performed. Analytical performance of TEST1 including precision, carryover, sample stability, potential interferences as well as effect of hematocrit (Hct) and mean corpuscular volume (MCV) were also determined.

Results

Strong correlation between three ESR measurement methods were observed. Correlation coefficient (r) was 0.902, 0.977, and 0.949 for WG vs. TEST1, WG vs. Mixrate, and TEST1 vs. Mixrate, respectively with absolute bias <5 mm. For TEST1, precision and carryover were within the manufacturer’s claim. Samples were stable upto 24 h and 48 h when they were stored at room temperature or 2–8 °C, respectively. No effect of trigyceride and cholesterol was observed. In low Hct samples, no significant different between the results obtained from Fabry’s formula corrected WG values and from TEST1.

Conclusions

Three-way comparison study yielded a strong correlation between methods. As part of the method validation before implementing a new analyzer, full validation of TEST1 showed that all validated parameters met the manufacturer’s specifications. A negative bias was observed but remains within the acceptable criteria. Difference in values for samples with low hematocrit were noted, but these can be corrected by Fabry’s formula applied to the values from WG method.
Iron in ventricular remodeling and aneurysms post-myocardial infarction
Authors: Wang Zuoyan , Ding Xiang , Pan Jingyu , Wang Xueyan , Lin Jieming , Wang Xinzhu
Published: December 2024

Background

Post-myocardial infarction (MI) complications, including ventricular remodeling (VR) and left ventricular aneurysm (LVA) formation, significantly affect patient prognosis and quality of life. Both iron overload and deficiency play critical roles in these pathological processes.

Objectives

This review aims to explore the mechanisms linking abnormal iron metabolism with post-MI VR and LVA formation and to highlight therapeutic strategies that regulate iron levels to mitigate adverse cardiac remodeling.

Methods

The review analyzes existing clinical and experimental research on the role of iron metabolism in post-MI complications. It focuses on iron overload, oxidative stress, ferroptosis, and the impact of iron deficiency on mitochondrial function, energy metabolism, and cardiomyocyte repair.

Results

Iron overload exacerbates myocardial injury through oxidative stress, ferroptosis, and inflammation, leading to fibrosis and ventricular dilation. In contrast, iron-deficiency impairs mitochondrial function, energy metabolism, and cardiomyocyte repair, further contributing to adverse remodeling outcomes. Therapeutic strategies such as iron chelators, ferroptosis inhibitors, and iron supplementation are potential interventions for mitigating adverse remodeling.

Conclusion

Abnormal iron metabolism, both overload and deficiency, plays a critical role in post-MI complications. Therapeutic strategies targeting iron levels hold promise for reducing adverse cardiac remodeling and improving patient outcomes after MI.

Published: December 2024

In this study, we prepared an inclusion complex of picoplatin (Pc) with 2-hydroxy propyl β cyclodextrin (HPCD) to improve its hydrophilicity, yielding Pc-HPCD. The Pc-HPCD complex was encapsulated into PEG-PLGA nanoparticles (NPs) using the emulsion–solvent evaporation method, yielding Pc-HPCD@PEG-PLGA core–shell NPs. The inclusion complex was assessed using 1HNMR spectroscopy and a phase solubility study. In addition, the average hydrodynamic diameter, polydispersity index, zeta potential, and encapsulation efficiency (EE%) of the Pc-HPCD@PEG-PLGA NPs were 190.2 ± 8.7 nm, 0.14 ± 0.02, −13.97 ± 0.67 mV, and 80.7 ± 2.4%, respectively. In vitro release study showed a pH-triggered release manner. Furthermore, the biological evaluation of Pc-HPCD@PEG-PLGA NPs revealed a significantly potent cytotoxic activity (IC50 = 1.6 ± 0.24 µg/ml) against triple-negative breast cancer cells (TNBC), surpassing that of Pc-HPCD (IC50 = 5.3 ± 0.93 µg/ml) and Pc (IC50 = 7.5 ± 0.4 µg/ml). Pc-HPCD@PEG-PLGA NPs induced significant apoptosis and the ability to arrest cells at the sub-G1 phase in MDA-MB-231 cells. Moreover, in an in vivo model established using SEC-bearing mice, treatment with Pc-HPCD@PEG-PLGA demonstrated significant inhibition of tumor proliferation (67.2%). This was accompanied by improvements in hematological and biochemical measurements, as well as histopathological examination, which indicated a reduction in cellular and nuclear pleomorphism. Our study demonstrated the potential of Pc-HPCD@PEG-PLGA NPs to be employed as an effective and safe therapy capable of conquering TNBC.

Published: December 2024

El sistema de humedales Marismas Nacionales Sinaloa (MNS), al noroeste de México, constituye un socio-ecosistema que suministra importantes servicios ecosistémicos (SE). Actualmente, MNS muestra signos de degradación vinculada con actividades antropogénicas, comprometiendo el flujo de SE, siendo necesario garantizar su continuidad, comenzando por su reconocimiento. Con ese objetivo, y mediante técnicas de cartografía social y colaboración participativa, se identificaron 28 sub-categorías de SE, principalmente de abastecimiento (57%). La cartografía generó información espacialmente explícita sobre las áreas suministradoras de SE y su relación con los usuarios. Se identificaron áreas prioritarias para los usuarios por su suministro de servicios ecosistémicos, como las marismas, manglares, sitios de importancia cultural y recreativa, y acuíferos. Se evidenció que las actividades relacionadas con los humedales se han incrementado en fechas recientes, indicando un aumento en la utilización de los recursos naturales, con interacciones negativas entre las actividades desarrolladas y los componentes naturales. Con este trabajo se aporta información base para futuros estudios en la región y se contribuye con elementos para el ordenamiento ecológico de MNS.

Published: December 2024

O lazer desempenha um papel fundamental no apoio ao bem-estar psicológico, social e emocional na velhice. Este artigo tem como objetivo explorar a relação entre lazer, lugar e renda a partir das perspectivas de idosos no Reino Unido e no Brasil e como a participação dos idosos no lazer apoia o desenvolvimento do senso de lugar dentro de suas comunidades. Os dados apresentados no artigo foram coletados por meio de uma abordagem de estudo de caso envolvendo três cidades no Brasil (Pelotas, Belo Horizonte e Brasília) e três no Reino Unido (Edimburgo, Manchester e Glasgow). Os achados baseiam-se em dados qualitativos coletados por meio dos seguintes métodos de pesquisa: entrevistas cara a cara, entrevistas caminhadas e diários fotográficos.
Os resultados mostraram que os bairros de baixa renda estudados tanto no Brasil quanto no Reino Unido tendem a ter menos oportunidades de lazer que passam a ser oferecidas por equipamentos como o CRAS (Centro de Referência de Assistência Social) e centros comunitários. A falta de oportunidades de lazer, principalmente em áreas de baixa renda, pode impactar negativamente na forma como os idosos vivenciam o senso de lugar em seus bairros.
A CIDADE EDUCADORA E AS DIFERENÇAS DE SEXO, SEXUALIDADE E GÊNERO
Authors: Da Silva Vital Rodrigo , Moreira Rocha Letícia
Published: December 2024

Considerando as ideias de cidade educadora, o presente estudo é um ensaio crítico que problematiza as relações educativas entre as cidades e os sujeitos que habitam, sobretudo no contexto da diversidade e/ou das diferenças de sexo, sexualidade e gênero. Para isso, nós fizemos uma análise argumentativa-interpretativa de uma pesquisa empírica, realizada em 2022 e que produziu conhecimentos sobre a relação das e dos estudantes LGBTI+ com/nas cidades, considerando a produção teórica de Michel de Certeau — os usos que os sujeitos fazem da/na cidade no cotidiano. Compreendendo que as relações com/no lugar ou cidade incide nas experiências de si das/dos estudantes LGBTI+, surge a hipótese de que toda cidade educa - uma educação que pode reforçar ou transformar a relação cidade-cisheteronormatividade sobre a inclusão-exclusão na urbanidade das pessoas LGBTI+.

Published: December 2024

O artigo é um relato de experiência sobre um projeto de extensão realizado por uma incubadora de Economia Solidária e duas cooperativas de agricultura familiar paranaenses, entre setembro de 2020 a agosto de 2021. O objetivo foi oferecer às cooperativas apoio tecnológico e em gestão para processos de venda não-presencial de modo a potencializar impactos positivos e superar as dificuldades agravadas pela pandemia de Covid-19. A equipe foi composta por membros da incubadora, docentes e discentes das áreas de Psicologia, Administração, Marketing e Tecnologia de Sistemas. A metodologia baseou-se na Educação Popular, tendo por princípios a dialogicidade, troca de saberes e participação; e envolveu realização de reuniões da equipe técnica e dessa com trabalhadores/as das cooperativas; aplicação da matriz FOFA; pesquisas com consumidores; coleta de requisitos, modelagem, prototipação, desenvolvimento, testes e implantação de um software de comércio eletrônico. Buscou-se que as tecnologias utilizadas e geradas se aproximassem dos princípios de Tecnologia Social e de Tecnociência Solidária (DAGNINO, 2010; 2019, 2020). O projeto alcançou os seguintes resultados: identificação das forças e fraquezas do ambiente interno das cooperativas; e das ameaças e oportunidades do ambiente externo; caracterização do perfil de consumidores/as; elaboração de um plano de fidelização e desenvolvimento de um sistema de comércio eletrônico. A necessidade do isolamento social e limites de recursos (financeiro, prazos, equipe) restringiram o atendimento de todas as demandas e um processo mais autogestionário. Espera-se que os saberes gerados no projeto sejam apropriados e aprimorados por outras incubadoras de Economia Solidária e empreendimentos econômicos solidários.

Published: December 2024

Na América Latina, o desenvolvimento hegemônico fortalece o agronegócio, cujo modelo segue a Revolução Verde com seus pacotes tecnológicos. Uma alternativa surge da crescente convergência de dois movimentos sociais: a agroecologia e a Economia Solidária (EcoSol), aqui denominada EcoSol-agroecologia. Suas redes constroem circuitos curtos, aproximando os produtores aos consumidores e fortalecendo suas bases. Para este estudo, as equipes de pesquisa desenvolveram metodologias de Pesquisa-Ação Participativa (PAR) com um parceiro comunitário que estava desenvolvendo circuitos curtos solidários. Durante a pandemia de Covid-19, as redes tiveram que fazer rápidas adaptações aos requisitos higiênicos; elaboraram, no curto prazo, uma prática recursiva entre ação e pesquisa. Como uma contribuição do artigo, identificou-se que essa rede está construindo capacidades coletivas em diversas formas de proximidade. Mais especificamente, propósitos comuns que ativam e vinculam outras proximidades (organizacionais, institucionais, culturais e geográficas) como relações solidárias. Tais capacidades coletivas ajudam as redes a resistir ao modelo agroalimentar hegemônico.

Authors: Mabvira Agrippa , Pillay Roshini , Masinga Poppy
Published: December 2024

In recent years, photovoice has gained considerable traction as a methodological approach for data collection. This article presents a reflexive account of our utilisation of photovoice for a qualitative doctoral research project that sought to capture the acculturation experiences of 12 immigrant adolescent learners in South Africa. Findings of the study offered rich and thick descriptions of co-researchers’ perspectives on how to foster successful acculturation, which is a testament to how photovoice revolutionises conventional research methodologies. Accordingly, this article argues that by embracing photovoice, social workers can develop more culturally sensitive and effective interventions, rooted in authentic experiences of service users. Therefore, this study aims to educate readers by providing a comprehensive overview of the phases that were undertaken in our photovoice project. In addition, the article, explores the benefits and challenges associated with the application of photovoice, shedding light on the intricacies of participant engagement through visual storytelling and illuminating the ways in which this method can augment research outcomes and amplify the voices of marginalised individuals.

Authors: Masombuka Jan , Skhosana Rebecca Mmamoagi
Published: December 2024

Substance misuse amongst young people continues to increase alarmingly. Sadly, parents are expected to rescue the situation and provide support to the young person. This article seeks to explore the knowledge and needs of parents with young persons misusing substances. The study was conducted at the 10 service points of the Gauteng Department of Social Development (DSD), in the City of Tshwane Metropolitan Municipality (CTMM). A qualitative research approach with non-probability purposive sampling was used to select 10 parents of young persons misusing substances. Face-to-face individual semi-structured interviews based on an interview guide were employed to collect the data. The data were analysed by using Tesch’s eight-step process of analysing factual data. Two themes with associated sub-themes emerged. A need was identified for parents to be better equipped and informed about substance misuse and how to deal with it to enable them to provide appropriate support to young persons.

CHALLENGING EXPERIENCES OF CUSTODIAL MOTHERS FOLLOWING THEIR DIVORCE: IMPLICATIONS FOR SOCIAL WORK PRACTICE
Authors: Zondi Thembelihle Vumokuhle , Kgadima Nathaniel Phuti
Published: December 2024

Although divorce leads to the separation of the parents, it does not proclaim the termination of the relationship between former partners but instead transforms it. Parents usually co-construct their roles to raise their children together. However, many studies have attested that divorce affects women more than men in many respects. This study was driven by the need to explore the challenging experiences of custodial mothers following their divorce. For this qualitative study, eleven custodial mothers who were divorced and co-parenting with former spouses were interviewed. Data were generated through semi-structured face-to-face interviews with open-ended questions in an interview guide. These were subsequently analysed thematically. Through purposive sampling and date collection, six themes emerged from the participants’ narratives. The results revealed that custodial mothers face challenges of strained communication, lone parenting and lack of fathers’ involvement in raising their children. The study recommends educating divorced parents, particularly on family therapy and mediation.

Participación, representatividad y democracia. Los movimientos sociales en la construcción de sistemas ético-políticos modernos en Latinoamérica
Authors: Ríos Sangucho Iván Patricio
Published: December 2024

Introduction. Today, social movements are considered to be key actors inthe development of politics worldwide. Their sudden appearance in this fieldis evidence of the emergence of new, alternative and necessary forms of social organization. Their intervention is marked by an aura of change and restitution of rights. In Latin America, these collectives arise from popular discontent and as a counterweight to political parties, evidencing a structural gap in the so-called representative democracies. Objective. In this context, the study seeks to analyze the importance of social movements in the construction of modern ethical-politicalsystems. Methodology. The research has a qualitative approach based on aliterature review from a conceptual and categorical basis. The concepts addressed include political systems, crisis of representation and plurality of identities, while the categories include democratization of power, loss of legitimacy of traditional political structures and recognition of diversity. Results. Social movements have contributed to reconfiguring power relations, promoting greater inclusion, justice and democratic sustainability, this as a consequence of a distrust in institutions and governance structures. Conclusions. It is concluded that social movements are a key element in the development of the so-called modern democracies in Latin America, since their participation generates spaces of representation and agency for socially and historically excluded groups in Latin America.
A Transformation of the Way of Thinking: Key Principles in Programming Education Inspired by Pascal
Authors: Dagienė Valentina , Grigas Gintautas , Jevsikova Tatjana
Published: December 2024

The work of Niklaus Wirth, designer of the Pascal programming language, has led to the introduction of programming in schools in many countries often leading to a transformation in the way of thinking. In this article, we provide a retrospective analysis of the Lithuanian experience driven by Pascal and discuss the main ideas about teaching programming originating from this experience. We conducted a qualitative study by means of interviews with experts involved in the development of programming education during its early phases to examine their memories and perspectives.
Programming education in Lithuania started with the Pascal-inspired Young Programmers’ School by Correspondence, founded in 1981, which had a great influence on the Lithuanian programming elite. For this purpose, a compiler for a subset of Pascal was developed for students taking their first steps towards programming, or more precisely, algorithmic thinking.
Many innovations were developed and brought into practice. The ones that have proved their worth and have not lost their relevance are the subject of this article. These include assessing program text readability, cultivating programming style, program reading tasks, creative thinking tasks, problem-solving approaches, detailed compiler error messages, automatic error fixing, and compiler advice to novice programmers. While some concepts became obsolete with technological advancements, others remain relevant, directly or as inspiration for new ideas, forming the basis of this study.

Pascal as the Driving Force of Informatics Education in Schools in Poland
Authors: Sysło Maciej M.
Published: December 2024

The first books in Polish about the Pascal programming language appeared in the late 1970s, and were soon followed by a Polish translation of Niklaus Wirth’s book Algorithms + Data Structures = Programs. At that time, many efforts were made to prepare teachers to teach informatics in schools, and Pascal was one of the topics taught, often with no access to computers.
The situation improved significantly after the first informatics curriculum was approved for schools by the Ministry of National Education (MEN) in 1985, in response to the increasing number of microcomputers in schools and students’ interest in programming. As a confirmation of the conclusions drawn from the discussion in the ABACUS magazine (1984) on “Which is the best programming language for a first course in computer science,” Pascal very quickly became the basic programming language in Polish schools as a tool for practicing algorithmics. The first informatics textbook was published in 1988 and in it, after a short Logo course, Pascal took the main place as a language for developing solutions to algorithmic problems in the form of computer programs.
In the following years, many teaching aids were developed for programming education in schools, as well as other aids, e.g., an authoring system, programmed in Pascal. Pascal was the primary programming language in informatics education until the end of the first decade of the 21st century, subsequently replaced by Python.
It is interesting that Polish winners of national and international Olympiads in Informatics for many years used Pascal, demonstrating the enormous professional values of this language.
In this article we present in detail, among others things: the role and influence of Pascal on the development and level of informatics education in schools in Poland, as well as other scientific activities and initiatives supported by this language. Many students educated in this technical and mental environment found their place in professional development teams in the best computer and technology corporations, and evidently most of them joined the national working force.

“I am air and fire...”: On the Interpretation of Anna Akhmatova’s Poem Cleopatra
Authors: Mikhailova Galina
Published: December 2024

In interpreting Akhmatova’s poem Cleopatra, attention is often primarily given to its historical and social parameters, which are involved in the poem’s meaning-making process. This article suggests focusing on the literary sources of the poem (Shakespeare’s tragedy Antony and Cleopatra and Horace’s ode), exploring Akhmatova’s working notes, different versions of the lyrical heroine in her poetry, as well as the reproduction of her image in poems dedicated to her, testimonies of memoirists, essays, and philological observations of Akhmatova’s contemporaries. In this case, the poem may be read within the framework of the poet’s intimate relationship with ‘being’, and it may turn out to be a space for the embodiment of the author’s essential personal characteristics.
Variations on the Themes of Netochka Nezvanova
Authors: Beržaitė Dagnė
Published: December 2024

The author of the article examines Fyodor Dostoevsky’s first multi-plot novel Netochka Nezvanova while also exploring the versions and reasons for the novel’s incompletion. The article suggests reading it in the context of the autobiographical works of Anna Grigorievna Dostoevskaya. The article draws a parallel between the first part of the novel about the musician Efimov and fragments from the Diaries and Memoirs of the writer’s wife. For the contemporary reader, accustomed to reading differently constructed texts, these fragments might be perceived as a kind of sequel to the early unfinished work (for example, the names of the novel’s heroine and the writer’s second wife, certain dates, behavioral models, and similar situations). The article suggests the idea that incorporating a literary text into the context of a writer’s biography is one way of ‘completing the incomplete’, while at the same time expanding the possibilities of interpreting classic works.

It iš one of the very first two textbooks on trigonometry which appeared at that time. We discuss and analyse mathematical terms and topics, presented in this textbook, and emphasize their significance for nowadays pedagogical science.
Dinamic of blood pluripotential stem cell formation processes
Authors: Švitra Donatas , Retkutė Renata
Published: December 2024

It has been suspected that periodical haematological deases arise because of abnormalities in the feedback mechanism that regulate blood cell number. It is generally believed that there exist the self maintaiting pluripotential stem cell population (PPSC) capable of producing committed stem cells specialised for the erithroid, myleoid or thromboid cell lines. The production of PPSC is regulated by two types of feedback mechanisms: (1) long range humoral mechanisms; (2) local environmental mechanisms. The property of these feedback mechanisms is the presence of time delays which arise, for example, because of finite cell maturation time. With the help of difference-differential equations the processes of the PPSC production are modeled. The models, which use logistic and Mono lows are linear analised and simulated by computer.

Geometric transformations in school geometry
Authors: Norvaiša Rimas
Published: December 2024

The study delves into the learning progression for school geometry based on transformations proposed by Hung-Hsi Wu. Plane transformations – translations, reflections, rotations, and dilations – are considered. Criteria for the triangle congruence and for triangle similarity, as well as the properties of the graphs of a quadratic function, are proved with their help. Axioms of school geometry used to justify the system of concepts are formulated. The study was motivated by the geometry topic presented in the mathematics curriculum as of 2022 and in the textbooks published.

Authors: Šilinskas Gintautas , Raižienė Saulė
Published: December 2024

This study investigated differences in teachers’ and parents’ perceptions about homework and their correlations with children’s achievement in Grade 4 – the end grade for primary school in Lithuania. Data were collected at the end of Grade 4 (February–March 2024). Teachers (n = 39) answered online questionnaires on homework frequency and expected homework time; parents (n = 525) completed paper questionnaires about homework frequency, time, and help. Children (n = 576) completed tests measuring literacy and math skills, and school administrations provided children’s Grade 4 grades and results from national standardized testing. Most parents and teachers reported that homework was assigned daily. Teachers reported that children should spend around one hour daily on homework; parents reported children spending on average one hour and ten minutes daily on homework and a great variation in the amount of weekly homework help children received. Compared to teachers, parents reported more frequent homework and more homework time. Only parental reports of time spent and help received for homework significantly correlated to children’s academic performance measures, albeit negatively. Overall, parents and teachers perceived homework time differently. Additionally, the less well Grade 4 students did academically, the more time they spent on homework, and the more help they required from family.
Effect of bisphosphonates on the anterior region of the mandible in a patient. A proposal of a clinical case
Authors: Chi Rivas Julio César , Escobedo Batista Lucia María
Published: December 2024

Bisphosphonate-induced osteonecrosis of the jaw is a severe complication that can occur in patients treated with these drugs, especially after oral surgical procedures. We present the case of a 79-year-old male patient who came to the clinic with pain and increased volume in the mandibular region. Despite initially denying relevant medical history, it was revealed that he had been on treatment with zoledronic acid for several years due to prostate carcinoma. After a surgical intervention to remove necrotic tissue, the patient developed osteonecrosis of the jaw, which complicated the healing and recovery process.

Introduction: Abdominal pain in the right hypochondrium (RHD) is a frequent cause for which people go to the emergency department, although acute cholecystitis is usually the main reason, there are multiple differential diagnoses, which is why it is necessary to establish a quick and accurate cause can be a clinical and imaging challenge. Ultrasound is usually the study of choice in hepatobiliary disorders, however, with DHD of other origins, where evaluation becomes a challenge for the radiologist.

Objective: To evaluate the relationship between pathological ultrasonographic findings with DHD in patients admitted for acute abdomen.

Material and methods: Descriptive cross-sectional study, in a hospital of the Mexican Social Security Institute, Puebla, Mexico, from July 2022 to June 2023, in patients aged 18 to 70 years, both sexes, admitted to the emergency room for acute abdomen. Sociodemographic and clinical variables were studied, where an ultrasonographic evaluation of all structures of the right hypochondrium was performed. Descriptive statistics and Kappa coefficient were used to evaluate the agreement between clinical diagnosis and ultrasound findings, with a significant p value <0.05, obtained using SPSS v27 and MedCalc® Statistical Software version 22.009 (MedCalc Software Ltd, Ostend, Belgium; https:/ /www.medcalc.org; 2023).

Results: 118 patients were studied, 69 (58.5%) women and 49 (41.5%) men. The most common comorbidities in women were diabetes and hypertension 34(49.3%), 11(16.0%) respectively, while in men diabetes predominated 23(46.9%) followed by hypertension 7(14.3%). Cholecystitis emerged as the main ultrasonographic finding in both sexes, followed by a normal USG in 15(21.8%) of women and 8(16.3%) of men. Despite this, considerable agreement [ƙ=0.78200] Standard error 0.040, approximate significance <0.001, 95% CI 0.70302-0.86098 was found between the initial ultrasound diagnosis and the definitive clinical diagnosis.

Conclusion: cholecystitis is a common primary diagnosis for pain in the right upper quadrant, considering gallbladder conditions as a primary etiology, however a high percentage of patients do not present pathological findings, underlining the complexity of the diagnosis in clinical practice and the need to consider other diagnostic modalities or less conventional etiologies as causes.
Advancements in autism: exploring innovative therapies and targeted approaches to management and reversal of neurodevelopmental disorders

Published: December 2024

This article explores effective treatment strategies for Autism Spectrum Disorders (ASD), focusing on innovative targeted therapies within the field of regenerative medicine. We reviewed and assessed the use of advanced regenerative techniques in treating ASD, highlighting new therapeutic modalities that address key pathological pathways associated with autism. The discussion includes cellular therapies, neuropeptide interventions, and treatments involving neuromediator precursors. Clinical outcomes were measured by improvements in behavioral, cognitive, and social functions. Patients with autism who received comprehensive biological therapy showed noticeable improvements in self-regulation and behavior within the initial weeks of treatment. By 2-3 months, significant progress was observed in eye contact, attention span, verbal responsiveness, and speech development. Follow-ups at six months indicated better communication skills and self-management. The addition of neuropeptides during the maintenance phase led to marked reductions in anxiety and aggression, and improved social skills and communication. Long-term therapy demonstrated sustained enhancements in conversational abilities, decreased repetitive behaviors, and improved social and emotional interactions. The combination of novel biological therapies and nutraceuticals appears to offer a promising approach to managing ASD, with significant gains in behavioral and cognitive outcomes. These results suggest the potential of regenerative medicine in improving ASD treatment and highlight the need for further research to refine treatment protocols and confirm long-term benefits.

It’s well known that sympathetic and sensory neurons are affected in the early stages of diabetes mellitus (DM). However, the functional disorders that occur in neurons of the superior cervical ganglion (SCG) under the conditions of DM remain insufficiently studied. Therefore, the aim of this study was to evaluate the effect of streptozotocin-induced diabetes mellitus (DM) of the rats on action potentials (AP) recorded in the superior cervical ganglion`s (SCG) neurons. Rats with blood sugar level more than 30 mM were taken into experiment. The SCG of healthy control rats (n=12), rats at week 4 (n=9), and rats at week 12 after streptozotocin injection (n=9) were studied in vitro. AP of the SCG neurons were registered by the microelectrode technique. Neurons of the SCG were stimulated directly with 150 ms depolarizing current in pulse of 100 pA. The AP parameters of 36 SCG neurons of control rats were alternately compared with the corresponding AP parameters of 22 neurons of rats at week 4 and 30 SCG neurons of rats at week 12 after streptozotocin injection. The data obtained demonstrate that the AP amplitude and overshoot of AP, maximum rise and fall rates, and afterhyperpolarization amplitude significantly decreased at 12 weeks after DM induction. At the same time, the rheobase value significantly increased, this may indicates decreasing of the neurons plasma membrane excitability. Only the AP maximum rate of fall decreased statistically significant at week 4, the maximum rate of rise had an insignificant tendency to decrease at that time. However, the resting membrane potential and excitation threshold didn’t change even at 12 weeks after the injection. Thus, functional disorders of rat SCG neurons were appeared at a quite late stage of DM. The differences in AP parameters may result from neurons’ membrane ionic conductivity alterations, decreasing of its excitability and reducing ion channels efficiency in later stages of DM. This suggests that SCG is an important target of pathophysiological disorders caused by DM.
