Authors: Rossoni Roger Alexandre , Moraes Marcelo Lopes de , Cattelan Renata
Published: January 2024

O objetivo desta pesquisa é analisar as mudanças ocorridas na população rural paranaense entre 2004 e 2014. Para tal, foram analisadas características da população e dos domicílios rurais paranaenses por meio de análises descritivas e utilização de alguns instrumentos estatísticos, como correlação de Pearson, além da estimação do Índice de Gini. Os dados utilizados foram retirados dos microdados da Pesquisa Nacional por Amostra de Domicílios (PNAD) referente ao Paraná, para os anos de 2004 e 2014. Os resultados demonstram indícios de melhora na condição de vida da população rural, com aumento da renda, da escolaridade e das condições dos domicílios. Contudo, apesar da suposta melhora na condição de vida, verifica-se a evasão, o envelhecimento da população rural e o crescimento das atividades não agrícolas como atividade principal da população rural paranaense.

Authors: Henrique Silva  Monteiro Pedro , Nunes de Lima Seixas Renato
Published: January 2024

Em novembro de 2015 ocorreu o rompimento da Barragem de Fundão, localizada no município de Mariana, em Minas Gerais, Brasil. Esse desastre tomou proporções enormes e, em relação aos danos causados as populações atingidas. Com objetivo de analisar a recuperação econômica de médio prazo (de 2016 a 2018) dos municípios atingido pelo desastre, foram estimados modelos de diferenças em diferenças canônicos e com efeitos dinâmicos para variáveis econômicas: PIB municipal; valor da produção animal; área colhida; valor da produção das lavouras de culturas temporárias e permanentes. Como grupo de controle foram utilizados todos os municípios pertencentes aos Estados de Minas Gerais e Espírito Santo, que não foram afetados pelo desastre. O grupo de tratamento é formado pelos municípios afetados direta e indiretamente pelo desastre. Os principais resultados apontaram para perdas nos municípios atingidos no que se refere ao valor da produção animal nos anos de 2016 e 2017 com uma recuperação já no ano de 2018. As estimações com efeitos dinâmicos para o valor da produção das lavouras também indicaram perdas dos municípios atingidos no ano de 2016, porém se observa uma trajetória de recuperação já a partir do ano de 2017 que se estende a 2018.
The study of mothernomics, its social benefits and organizational impact
Authors: Angasinha Chatwarun , Lipipun Vichaya
Published: January 2024

The economics of motherhood presents a dual role in society, serving as both an asset and a liability (Harkness, 2018; Miller, 2018). This qualitative study explores mothernomics and its implications in Thailand and benchmarks Thailand relative to five other countries (Sweden, Japan, Australia, Singapore, and Vietnam), examining early childhood care and parental leave through documentary and content analysis. Notably, Sweden’s extensive partner leave, Japan and Australia’s combined before and after birth leave, and Singapore’s balanced approach contrast with Thailand’s limited support. Adaptable and comprehensive policies are underscored, catering to evolving family dynamics, enhancing parental well-being, and contributing to an inclusive societal framework. This study emphasizes the multi-dimensional nature of mothernomics, advocating for holistic strategies that address the economic, social, and cultural dimensions of Thai motherhood. This approach is pivotal for harnessing motherhood’s role in driving societal progress, enabling gender equality, valuing caregiving, and robustly supporting working mothers. Policymakers should consider workplace challenges and societal roles to ensure meaningful maternal participation, advancing overall societal well-being in Thailand.

Systemic lupus erythematosus - diagnosis and classification of the disease in the past and in present times
Authors: Zivkovic Valentina , Stamenkovic Bojana , Stojanovic Sonja
Published: January 2024

The main feature of systemic lupus erythematosus (SLE) is its heterogeneity, which mainly refers to clinical presentation, the course of disease and prognosis which can impact any or many organs and various immunoserological tests. As a result, prompt illness recognition and right diagnosis are extremely complicated processes based on the most recent classification standards and the doctor's clinical expertise with specific patients. In contrast, not all SLE patients are included when using classification criteria, which are based on a definition of a homogenous group by the specified, restricted number of clinical and immunoserological domains and for the purpose of conducting clinical or epidemiological investigations. Classification criteria have evolved over the last fifty years in response to new understandings and advances. This process began with the ACR criteria in 1971 and continued through their updates in 1982 and 1997, followed by SLICC 2012 and EULAR/ACR 2019. EULAR/ACR 2019 criteria have proven their high validity (sensitivity and specificity) in numerous studies, as well as adequate diagnostic usefulness, defined by 24 items in 10 domains, with the fulfillment of the essential precondition of antinuclear antibody positivity
Pulmonary Function Trajectories Over 6 Years and Their Determinants in Type 2 Diabetes: The Fremantle Diabetes Study Phase II
Authors: Davis Timothy M.E. , Drinkwater Jocelyn J. , Davis Wendy A.
Published: January 2024

OBJECTIVE

To assess whether there are clusters of people with type 2 diabetes with distinct temporal profiles of lung function changes and characteristics.

RESEARCH DESIGN AND METHODS

Group-based trajectory modeling (GBTM) identified groups of participants with type 2 diabetes from the community-based observational Fremantle Diabetes Study Phase II (FDS2) who had at least two biennial measurements of forced expiratory volume in 1 s as a percentage of predicted (FEV1%pred) over 6 years. Independent associates of group membership were assessed using multinomial regression.

RESULTS

Of 1,482 potential FDS2 participants, 1,074 (72.5%; mean age, 65.2 years; 45.5% female; median diabetes duration, 8.0 years) were included in the modeling. The best fitting GBTM model identified four groups categorized by FEV1%pred trajectory: high (19.5%; baseline FEV1%pred, 106.5 ± 9.5%; slope 0%/year), medium (47.7%; FEV1%pred, 87.3 ± 8.7%; slope, −0.32%/year), low (25.0%; baseline FEV1%pred, 68.9 ± 9.8%; slope, −0.72%/year), and very low (7.9%; baseline FEV1%pred, 48.8 ± 9.6%; slope, −0.68%/year). Compared with the high group, the other groups were characterized by nonmodifiable and modifiable risk factors associated with lung function decline in the general population (including ethnicity, marital status, smoking, obesity, coronary heart disease, and chronic respiratory disease). The main, diabetes-specific, significant predictor of group membership was a higher HbA1c in the very low group. There was a graded increase in mortality from 6.7% in the high group to 22.4% in the very low group.

CONCLUSIONS

Measurement of lung function in type 2 diabetes could help optimize clinical management and improve prognosis, including addressing glycemic control in those with a very low FEV1%pred.

Authors: Cho Eunjung , Park Jung Tak , Yoo Tae-Hyun , Kim Soo Wan , Park Cheol Whee , Han Seung Seok , Kim Yeong Hoon , Kwon Young Joo
Published: January 2024

Background: Fabry disease (FD) is an X-linked lysosomal storage disorder caused by the deficient activity of α-galactosidase A (α-Gal A) enzyme, affecting multiple organs including kidney. In this study, we aimed to determine the prevalence of FD in patients with chronic kidney disease (CKD) including those on renal replacement therapy in Korea.Methods: This is a national, multicenter, observational study performed between August 24, 2017 and February 28, 2020. Patients with the presence of proteinuria or treated on dialysis were screened by measuring the α-Gal A enzyme activity using either dried blood spot or whole blood, and plasma globotriaosylsphingosine (lyso-GL3) concentration. A GLA gene analysis was performed in patients with low α-Gal A enzyme activity or increased plasma lyso-GL3 concentration.Results: Of 897 screened patients, 405 (45.2%) were male and 279 (31.1%) were on dialysis. The α-Gal A enzyme activity was measured in 891 patients (99.3%), and plasma lyso-GL3 concentration was measured in all patients. Ten patients were eligible for a GLA gene analysis: eight with low α-Gal A enzyme activity and two with increased plasma lyso-GL3 concentration. The GLA mutations were analyzed in nine patients and one patient was found with a pathogenic mutation. Therefore, one patient was identified with FD, giving a prevalence of 0.1% (1 of 897) in this CKD population.Conclusion: Although the prevalence of FD in the CKD population was low (0.1%), screening tests are crucial to detect potential diseases in patients with relatives who can benefit from early treatment.

Published: January 2024

Background: In patients with type 2 diabetes mellitus (T2DM), diabetic kidney disease (DKD) is diagnosed based on clinical features. A kidney biopsy is used only in selected cases. This study aimed to reconsider the role of a biopsy in predicting renal outcomes. Methods: Clinical and laboratory parameters and renal biopsy results were obtained from 237 patients with T2DM who underwent renal biopsies at Soonchunhyang University Cheonan Hospital between January 2000 and March 2020 and were analyzed. Results: Of 237 diabetic patients, 29.1% had DKD only, 61.6% had non-DKD (NDKD), and 9.3% had DKD with coexisting NDKD (DKD/NDKD). Of the patients with DKD alone, 43.5% progressed to end-stage kidney disease (ESKD), while 15.8% of NDKD patients and 36.4% of DKD/NDKD patients progressed to ESKD (p < 0.001). In the DKD-alone group, pathologic features like ≥50% global sclerosis (p < 0.001), tubular atrophy (p < 0.001), interstitial fibrosis (p < 0.001), interstitial inflammation (p < 0.001), and the presence of hyalinosis (p = 0.03) were related to worse renal outcomes. The Cox regression model showed a higher risk of progression to ESKD in the DKD/NDKD group compared to the DKD-alone group (hazard ratio [HR], 2.73; p = 0.032), ≥50% global sclerosis (HR, 3.88; p < 0.001), and the degree of mesangial expansion (moderate: HR, 2.45; p = 0.045 and severe: HR, 6.22; p < 0.001). Conclusion: In patients with T2DM, a kidney biopsy can help in identifying patients with NDKD for appropriate treatment, and it has predictive value.

Published: January 2024

Mangroves are one of the most important types of wetlands in coastal areas and perform many different functions. Assessing the structure and function of mangroves is a premise for the management, monitoring and development of this most diverse and vulnerable ecosystem. In this study, the unmanned aerial vehicle (UAV) Phantom 4 Multispectral was used to analyse the structure of a mangrove forest area of approximately 50 hectares in Dong Rui commune, Tien Yen district, Quang Ninh Province – one of the most diverse wetland ecosystems in northern Vietnam. Based on the visual classification method combined with the results of field taxonomic sampling, a mangrove tree classification map was established for UAV with three species, Bruguiera gymnorrhiza, Rhizophora stylosa, and Kandelia obovata, achieving an overall accuracy = 86.28%, corresponding to a Kappa coefficient =0.84. From the images obtained from the UAV, we estimated and developed maps and assessed the difference in tree height and four vegetation indices, including the normalized difference vegetation index (NDVI), green normalized difference vegetation index (GNDVI), enhanced vegetation index (EVI), and green chlorophyll index (GCI), for three mangrove plant species in the flying area. Bruguiera gymnorrhiza and Rhizophora stylosa reach an average height of 4 to 5 m and are distributed mainly in high tide areas. Meanwhile, Kandelia obovata has a lower height (ranging from 2 to 4 m), distributed in low-tide areas, near frequent flows. This study confirms the superiority of UAV with red edge and near-infrared wave bands in classifying and studying mangrove structures in small-scale areas.
The Aerosol Pollution Of The Atmosphere On The Example Of Lidar Sensing Data In St. Petersburg (Russia), Kuopio (Finland), Minsk (Belarus)
Authors: Samulenkov D. A. , Sapunov M. V.
Published: January 2024

The results of lidar sensing of aerosol pollution in St. Petersburg (Russia) were compared with ones located in Minsk (Belarus) and Kuopio (Finland) to assess the impact of large cities on atmospheric pollution by aerosol particles. For comparison, aerosol optical depth (AOD) data obtained at the three stations from 2014 to 2021 were used. Lidar sounding of atmospheric aerosols was carried out using aerosol Nd:YAG lasers operating at three wavelengths: 355, 532 and 1064 nm. Due to differences in the lidar station equipment characteristics and, consequently, in the lower limit for determining aerosols, the aerosol optical depth was compared in the range of heights from 800 to 1600 m at 355 and 532 nm. Since the compared stations do not have data for all years, the period from 2014 to 2016 was analyzed separately. The average annual AOD 355 in Minsk in the period 2014-2016 is almost the same as the average annual AOD in St. Petersburg. When comparing data in St. Petersburg and Minsk for the period 2014-2020, AOD 355 in St. Petersburg exceeds AOD 355 in Minsk by 1.46 times. AOD 532 nm in Minsk is larger than in St. Petersburg, regardless of the chosen comparison period. The average annual AOT 355 in Kuopio is lower than in Minsk and St. Petersburg by 2.1 times, while at a wavelength of 532 nm they are 3.6 times lower than in Minsk and 2.6 times in St. Petersburg. The calculated Angstrom exponent coefficient shows that the coarse mode in Minsk is higher than in St. Petersburg. The atmosphere over Kuopio has a lower content of aerosol particles. Since 2017, there was a steady excess of aerosol content over St. Petersburg compared to Minsk. Additionally, a comparison of the lidar data with the total AOD of AERONET stations located in Kuopio, Minsk and Peterhof (25 km from the lidar station in St. Petersburg) was carried out. The AOD obtained by lidar and AERONET method is in good agreement.

In 2022, central nervous system (CNS) tumor with BCOR internal tandem duplication (BCOR ITD) was included in the fifth edition of the World Health Organization Classification of Tumors of the CNS as part of the embryonal tumor group. The identification a distinct DNA methylation profile and the presence of a recurrent genetic aberration – BCOR ITD – made it possible to recognize these tumors as a separate entity. In most cases, these tumors occur in children under 5 years of age and are located in the hemispheres of the cerebellum or brain. Since CNS tumor with BCOR ITD is a rare and relatively new tumor entity, it is not yet widely known and can be misdiagnosed. The most common initial diagnosis in patients referred for a second opinion to our reference center is anaplastic/classical medulloblastoma. In this article, we aimed to summarize the characteristic clinical, morphological and immunophenotypic features of CNS tumors with BCOR ITD based on 8 clinical cases confirmed by molecular genetic testing. The study was approved by the Independent Ethics Committee and the Scientific Council of the Dmitry Rogachev National Medical Research Center of Pediatric Hematology, Oncology and Immunology.
Intraoperative red blood cell salvage in cancer surgery
Authors: Guz I. V. , Trakhtman P. E. , Shchukin V. V. , Motovitskaya A. V.
Published: January 2024

Surgery in cancer patients may sometimes involve significant blood loss, and intraoperative red blood cell salvage is an effective technique that can reduce postoperative complications. Autologous reinfusion of red blood cells processed by a cell saver machine significantly reduces the number of red blood cell transfusions from donors. The use of leukocyte filters eliminates the possibility of tumor cell release into the patient’s circulation. This method is easy to use, however medical staff should be appropriately trained in cell salvage. Intraoperative red blood cell salvage can and should be used in the management of patients undergoing planned or emergency surgeries with expected blood loss > 500 mL.

Authors: Abd El Baset Abd El Halim Ahmed , Eid Bayoumi Ehab Hassan , El-Khattam Walid , Ibrahim Amr Mohamed
Published: January 2024

This article examines in depth the most recent thermal testing techniques for lithium-ion batteries (LIBs). Temperature estimation circuits can be divided into six divisions based on modeling and calculation methods, including electrochemical computational modeling, equivalent electric circuit modeling (EECM), machine learning (ML), digital analysis, direct impedance measurement, and magnetic nanoparticles as a base. Complexity, accuracy, and computational cost-based EECM circuits are feasible. The accuracy, usability, and adaptability of diagrams produced using ML have the potential to be very high. However, both cannot anticipate low-cost integrated BMS live due to their high computational costs. An appropriate solution might be a hybrid strategy that combines EECM and ML.
A Novel Artificial Intelligence-Based Hybrid System to Improve Breast Cancer DetectionUsing DCE-MRI

Published: January 2024

The interpretation of breast magnetic resonance imaging (MRI) in the healthcare field depends on the good knowledge and experience of radiologists. Recent developments in artificial intelligence (AI) have shown advances in the field of radiology. However, the desired levels have not been reached in the field of radiology yet. In this study, a novel model structure is proposed to characterize the diagnostic performance of AI technology for individual breast dynamic contrast material–enhanced (DCE) MRI sequences. In the proposed model structure, Inception-v3, EfficientNet-B3 and DenseNet-201 models were used as hybrids together with the Yolo-v3 algorithm to detect breast and cancer regions. In the proposed model, DCE-MRI sequences (T2, ADC, Diffusion, Non-Contrast Fat Non-Suppressed T1, Non-Contrast Fat Suppressed T1, Contrast Fat Suppressed T1, and Subtraction T1) were evaluated separately and validation was made, thus providing a unique perspective. According to the validation results, the model structure with the best performance was determined as Yolo-v3 + DenseNet-201. With this model structure, 92.41 accuracy, 0.5936 loss, 92.44% sensitivity, and 92.44% specificity rates were obtained. In addition, it was determined that the results obtained without using contrast material in the best model were 91.53% accuracy, 0.9646 loss, 92.19% sensitivity, and 92.19% specificity. Therefore, it is predicted that the need for contrast material use can bereduced with the help of this model structure.

Authors: Białkowska Anita , Suroń Patryk , Kucharczyk Wojciech , Hanulikova Barbora , Bakar Mohamed
Published: January 2024

The present work investigated the effect of modifying an epoxy resin using two different modifiers. The mechanical and thermal properties were evaluated as a function of modifier type and content. The structure and morphology were also analyzed and related to the measured properties. Polyurethane (PUR) was used as a liquid modifier, while Cloisite Na+ and Nanomer I.28E are solid nanoparticles. Impact strength (IS) of hybrid nanocomposites based on 3.5 wt% PUR and 2 wt% Cloisite or 3.5wt% PUR and 1wt% Nanomer was maximally increased by 55% and 30% respectively compared to the virgin epoxy matrix, exceeding that of the two epoxy/nanoparticle binaries but not that of the epoxy/PUR binary. Furthermore, a maximum increase in IS of approximately 20% compared to the pristine matrix was obtained with the hybrid epoxy nanocomposite containing 0.5 wt% Cloisite and 1 wt% Nanomer, including a synergistic effect, due most likely to specific interactions between the nanoparticles and the epoxy matrix. The addition of polyurethane and nanoclays increased significantly the thermal stability of epoxy composites. However, DSC results showed that the addition of flexible polyurethane chains decreased the glass transition temperatures, while the softening point and the service temperature range of epoxy nanocomposites containing nanofillers were increased. FTIR analysis confirmed the occurrence of interaction between the epoxy matrix and added modifiers. All SEM micrographs showed significant roughness of the fracture surfaces with the formation of elongated platelets, explaining the increase in mechanical properties of the epoxy matrix.

Magnetic collars improve owner-reported pain scores in dogs with osteoarthritis in a blinded crossover study
Authors: Picton Fiona A. , Fontaine Samantha J. , McBrearty Alix R.
Published: January 2024

OBJECTIVE

To investigate changes in owner-reported pain, interference of pain on function, and quality of life (QOL) in dogs with clinically suspected osteoarthritis when wearing a collar containing a static magnet.

ANIMALS

16 dogs over 5 years old weighing between 10 and 40 kg with a clinical diagnosis of osteoarthritis and on stable treatment.

METHODS

A prospective, blinded crossover study in which dogs wore a collar containing a static magnet or placebo for two 4-week study arms separated by a 2-week washout period. Clients completed the Canine Brief Pain Inventory prior to collar placement and then weekly throughout each arm. Changes in QOL, pain severity, and pain interference scores from the beginning to the end of these arms and changes between the arms were calculated and analyzed using Wilcoxon signed rank tests.

RESULTS

40% of included dogs were on stable doses of NSAIDs. The pain severity scores (PSS), pain interference scores (PIS), and QOL scores were not significantly different at the start of the arms. There was no significant change in PSS or PIS from the start to end of the placebo arms (median changes, 0 and –0.1). Both PSS and PIS reduced significantly during the magnet arms (median changes, –1.0 and –1.2, respectively). The QOL scores did not change significantly in either arm (median changes, 0 and 0).

CLINICAL RELEVANCE

This preliminary study suggests that magnetic collars reduce owner-reported pain severity and pain interference on function in dogs with clinically suspected osteoarthritis, and further, larger investigations are now warranted.
WAYS TO PRESERVE CULTURAL FOLK TRADITIONS AND NATIVE LANGUAGE ON THE EXAMPLE OF ANALYSIS OF “LEMANTAR” BY I.A. GLADKY
Authors:   Brest State A. S. Pushkin University, Maksymuk L.M. , Levoniuk L.E. ,   Brest State A. S. Pushkin University
Published: January 2024

The article discusses the issues of preserving the traditions of Belarusian people, transferring knowledge about their culture to the younger generation through textbooks intended for studying the Belarusian language. Using the example of the analysis of “Lemantar” (primer book), compiled by I.A. Gladky (Adam Varlyga, 1890–1972), a professional teacher and enthusiast of the Belarusian language, shows how the teaching of the native language and culture was carried out in families and schools created for children of Belarusian origin living far from their homeland. “Lemantar” consists of two parts, the first of which is written in Latin, and the second in Cyrillic, since Belarusians have used both fonts for a long time. In the primer, the Latin font is the leading or guiding one, since from a scientific point of view it is best suited for reflecting the expressiveness of the sounds of the Belarusian language. Moreover, this teaching order meets pedagogical and methodological requirements, since it is a single complex with a gradual transition from foreign writing to the native language with all its features. A detailed phonetic, grammatical and linguistic analysis of each part of the primer is presented. Particular attention is paid to the analysis of the content of the textbook, especially its second part. It is emphasized that teaching the linguistic and cultural realities of the Belarusian people is based on poems, conversations on various topics, folk tales and parables, which contributes to a deeper understanding of the mentality of Belarusians, as well as introducing children to universal values. It is concluded that teaching aids like “Lemantar”, rich in regional studies and linguistic material, conveying the flavor of the life of Belarusian people, their lifestyle, holidays, family and work traditions, are of particular relevance, because, on the one hand, they reproduce ethnic tradition aimed at preserving national culture, on the other hand, include international subjects that are read as existentially important for any person.
TOOLS FOR THE FORMATION OF SOFT SKILLS IN FOREIGN LANGUAGE EDUCATION
Authors:   Bunin Yelets State University, Pilyugina A.A.
Published: January 2024

The article is devoted to the problem of the formation of soft skills in the process of teaching a foreign language. Modern workers are characterized by greater autonomy in decision-making, as well as fewer repetitive tasks and the need to work with people at all levels of labor organization. Such changes require an additional new set of skills for the members of the organization. As a result of the alignment of the traditional organizational hierarchy, employees at all levels must now possess “soft” skills. Today, the problem of the formation of soft skills remains relevant due to the insufficient study of this issue in the pedagogical literature. Soft skills are not a pedagogical problem, but belong to the sphere of interests of psychology. Therefore, the search for methods and technologies for the formation of these skills is still relevant. Soft skills are an important part of the professionalism of a specialist of any profile. The concept of “soft skills” has a broad interpretation, however, both European and Russian researchers of this problem identify a number of common features for all definitions, namely: communication, critical thinking, problem-solving ability, creative thinking, ability to cooperate, time management, ability to work in a team, leadership. Soft skills are a set of supra-professional skills and personality qualities that are in demand in the labor market for the effective implementation of professional competencies.The author of the article describes the ways of their formation: direct and indirect. Analyzing his own pedagogical experience, the author offers two tools for the formation of soft skills in the process of teaching a foreign language. A trend session is an effective way of organizing group work aimed at developing such important skills as the ability to communicate, work in a team, and the ability to organize effective cooperation. Foresight technology is aimed at developing the skills of foreseeing the development of the situation, planning and organizing cooperation.

Objective:
This study aimed to measure the level of knowledge and practice of mothers on newborn care and the use of social media as a source of newborn care information by those mothers.
Methods:
This was an observational, descriptive cross- sectional study that was conducted at three primary health care (PHC) centers including Health Care Specialty Center (HCSC), King Abdulaziz City Housing (Iskan), National Guard Comprehensive Specialized Clinic (NGCSC) and Obstetric and Gynecologic clinics 101 (KAMC) in Riyadh, Saudi Arabia. A self-administered questionnaire was distributed amongst 400 Saudi mothers to collect the data.
Results:
This study included 346 participants with a mean age of 32.01±6.388 years. More than half (n=208, 60.1%) participants got an average knowledge score. Additionally, 57.6% (n=196) women breast fed their children after birth, while 61.7% (n=208) gave colostrum milk. Further, 95% (n=323) women considered that the information from social media was not sufficient. It was found that mothers with educational level up to high school level, had higher average scores of knowledge (66.9%) as compared to the women with university level who had (57.4%) a less average score of knowledge, and this was a significant difference. It was also found that mothers who took information from their doctors had high average knowledge scores (69.8%) and this was again a considerable difference.
Conclusion:
The study revealed significant gaps in mothers' knowledge of certain child health matters. Health education in hospitals before delivery and upon discharge needs to be more regularized and supervised.

The present comprehensive review focuses on maxillary expansion techniques, with a particular emphasis on Rapid Maxillary Expansion (RME). The study aims to compare the effectiveness, stability, and various techniques in adults with skeletal maxillary transverse discrepancies. The review discusses maxillary expansion concepts, appliances, forces, mechanisms, and the dental, skeletal, and nasal impacts. It also examines the challenges associated with traditional RME in adult patients and explores advancements in surgical procedures to address these challenges. The current review emphasizes Surgically Assisted Maxillary Expansion (SARME) as a successful and more stable treatment approach for adults requiring palatal expansion, minimizing tooth tipping, and optimizing skeletal correction.

Point prevalence surveys (PPSs) provide valuable insights into several aspects of hospital prescription trends, specifically regarding antibiotic usage. Hence, this review was conducted to investigate the point prevalence of antibiotic use. This was an updated systematic review of the previous two years addressing studies conducted between the years 2021 and 2023 regarding the point prevalence of antibiotic use. Studies regarding the current topic were examined using the PubMed, Cochrane, Web of Science, and Google Scholar databases. The terms were employed in different combinations including the \"Point prevalence, survey, antibiotics use, antimicrobial prescribing, antimicrobial resistance, antimicrobial stewardship; surveillance, hospital, private sector, global health security\". Publications in full text were used as the inclusion criterion. Out of the 85 acquired articles, only nine were deemed suitable for inclusion. The analysis encompassed more than 10,331 hospitalized patients in different regions. This systematic review demonstrated a high point prevalence of antibiotic use in hospitals. The most prevalent clinical indications were pneumonia, skin and soft tissue infections, sepsis, and community-acquired infections. Ceftriaxones were the predominant antibiotics provided to patients. These hospitals have a high incidence of use of antibiotics, but they lack institutional frameworks and protocols to ensure optimal antibiotic use. The study furnishes the requisite data for enhancing forthcoming antibiotic utilization in hospitals and mitigating antimicrobial resistance. These findings emphasize the importance of ongoing efforts to improve the responsible use of antibiotics by implementing effective antimicrobial stewardship programs in hospitals, ultimately leading to decreased antimicrobial resistance in the country.

Published: January 2024

Background:
The coexistence of extrahepatic portal vein thrombosis (EHPVT) and sickle-cell disease (SCD) was documented in a young adult patient who was presented with vague gastrointestinal symptoms, including right upper quadrant abdominal pain associated with fever and jaundice. Diagnosing EHPVT in children can be challenging due to ambiguous presentation and the lack of sufficient literature, particularly in those with SCD.
Case Presentation:
A five-year-old boy with homozygous sickle-cell (SS) disease presented to the emergency department with subjective fever and abdominal pain. The patient was managed conservatively with intravenous (IV) fluids, antibiotics, and analgesics. After admission, the patient was found to have hypoalbuminemia, anemia, and thrombocytopenia. Abdominal ultrasound showed moderate ascites with bowel loop thickness and preserved vasculature. Later, the boy developed increased abdominal pain. Abdominal computed tomography (CT) with contrast showed hepatic, portal, superior mesenteric and splenic veins thrombosis.
Conclusion:
Venous thrombosis is rare in SS disease, and its occurrence in this disease raises the possibility of a common pathogenesis and adds another pathology to the causes of abdominal pain in sickle-cell disease.
Criterios e indicadores para evaluar mecanismos de participación ciudadana desde el enfoque de derechos humanos
Authors: Yoma Solana María
Published: January 2024

Contexto: este artículo busca tender puentes entre dos campos de indagación e intervención que, a nivel de la academia y los organismos internacionales, se encontraban hasta el momento desarticulados: las evaluaciones con enfoque de derechos humanos y las evaluaciones de procesos participativos. En ese marco, nos propusimos construir criterios e indicadores para evaluar los mecanismos institucionales de participación ciudadana desde el enfoque de derechos humanos. Métodos: llevamos a cabo una revisión teórica y normativa mediante la que procuramos identificar las características definitorias de las evaluaciones con enfoque de derechos humanos y el modo en que podrían aplicarse en la evaluación de mecanismos participativos. Resultados: elaboramos un marco conceptual y operativo para evaluar mecanismos de participación ciudadana desde estándares y dimensiones de derechos humanos y construimos una matriz de indicadores (cuantitativos y cualitativos, objetivos y subjetivos, de estructura, procesos y resultados) que permitirá incorporar diferentes fuentes y perspectivas en la evaluación de estas experiencias. Conclusiones: estos criterios e indicadores pretenden aportar en los procesos de monitoreo internacionales sobre el derecho a la participación ciudadana y servir a los fines de la ciudadanía para evidenciar y reclamar en casos de incumplimiento.
A Study on the Method of Teaching by Connecting Reading·Debate·Writing
Authors:   The Research Society for the Korean Language Education, Kim Chae Bong
Published: January 2024

The purpose of this article is to provide education in connection with reading·debate·writing as a way to maximize the advantages and compensate for segmental education. The following is a summary of the research content and a conclusion based on it. First, segmental education is efficient to strengthen the foundations and basics, but it lacks flexibility to contain the nature and results of flexible thinking activities, so linkage education is needed to strengthen language use skills by strengthening the link between functions. Second, linkage education can be conducted around the composition of sub-units, and sub-units can be composed like ‘reading→reading‧debate→reading‧writing→reading‧debate‧writing’, ‘writing→writing‧debate→writing‧reading→reading‧debate‧writing’, ‘debate→debate‧reading→debate‧writing→reading‧debate‧writing’. Third, when selecting a book, the goal of the class, the stage of the learner’s development, and the learner’s interest must be considered. Forth, the points that should be used for the association activites that are the basis for each language function are follows. In the case of reading, intellectual action should be performed in consideration of the reader’s background, the nature of the reading material, and the criteria for performing the task. in the case of writing, we should follow the rules in consideration of the purpose writing and do systematic writing activities through appropriate division of labor. Do it. In the case of debate, you should use reading and writing at the same time to have a debate, but clarify the method and direction of the debate.

Responding to Palestinian organizers' calls to use our voice, continue to engage in conversations, and to speak out, this statement articulates what we see as the abolitionist and anti-colonial way forward—the only way we can commit to a free Palestine. Imagining and building alternatives is the future, the horizon of possibility, that Lateral, as part of the intellectual and activist project of cultural studies, is imperfectly but consistently striving toward. Here, we highlight work in this issue, including the Towards Third Worlding forum, articles, book reviews, and the second installment of the Positions podcast. We continue to welcome authors to join in this work of pushing the field of cultural studies further, towards its promise of critical inquiry matched by political engagement.
ATIVISMO NO JORNALISMO DO CENTRO DO MUNDO
Authors: Gould Luiza
Published: January 2024

RESUMO – Este artigo parte de um resgate crítico da noção de objetividade jornalística para investigar como produções engajadas, que deixam transparecer posicionamentos e vieses, podem gerar enfrentamentos à desumanização. Para tanto, integram o corpus da pesquisa duas reportagens e um editorial que denunciam o genocídio do povo indígena Yanomami no Brasil durante o governo de Jair Bolsonaro (2019-2022). Os textos foram publicados por Sumaúma, plataforma idealizada pela jornalista brasileira Eliane Brum junto a outros quatro colegas com o intuito de contar histórias da Amazônia e defendê-la. Constatamos, a partir da análise de discurso (Orlandi, 2005), que esses textos geram significados específicos a partir de sua inscrição numa perspectiva de jornalismo de subjetividade (Moraes, 2022), com potencial de reflexividade e ação.
ABSTRACT – This article starts from a critical rescue of the notion of journalistic objectivity to investigate how engaged productions, which reveal positions and biases, can generate confrontations against dehumanization. To this end, the research corpus includes two in-depth reports and an editorial that denounce the genocide faced by the Yanomami indigenous people in Brazil during Jair Bolsonaro’s government (2019-2022). Sumaúma, a platform created by Brazilian journalist Eliane Brum with four other colleagues to tell stories about the Amazon and defend it, published both contents. Through discourse analysis (Orlandi, 2005), we found that these texts generate specific meanings based on their inscription in a perspective of subjective journalism (Moraes, 2022), with potential for reflexivity and action.
RESUMEN – Este artículo parte de un rescate crítico de la noción de objetividad periodística para investigar cómo producciones comprometidas, que revelan posiciones y sesgos, pueden generar confrontaciones con la deshumanización. Para ello, el corpus de investigación incluye dos reportajes en profundidad y un editorial que denuncian el genocidio del pueblo indígena Yanomami en Brasil durante el gobierno de Jair Bolsonaro (2019-2022). Ambos contenidos fueron publicados por Sumaúma, una plataforma creada por la periodista brasileña Eliane Brum junto a otros cuatro colegas para contar historias sobre la Amazonía y defenderla. Verificamos desde el Análisis del Discurso (ORLANDI, 2005) que estos textos generan significados específicos a partir de su inscripción en una perspective de Periodismo de la Subjetividad (MORAES, 2022), con potencial para la reflexividad y la acción.
