Authors: Lemos-Rodriguez Ana , Lenis Juan Pablo , Arias-Valderrama Oriana , Arrieta Elizabeth , Guzman Guillermo Edinson , Garcia Andres Octavio
Published: February 2025

BACKGROUND

To identify the key prognostic factors in patients with primary and secondary thyroid lymphoma, focusing on clinical, histopathological, biological, and genetic components, as these factors remain unclear.

OBJECTIVE

To analyze and synthesize the available evidence to identify factors that may influence the prognosis of patients with primary and secondary thyroid lymphoma.

METHODS

This review will include indexed databases such as LILACS, MEDLINE, EMBASE, and PubMed as the primary search sources. The search will cover the period from June 1, 2024, to July 1, 2024. Eligibility criteria will include observational studies of human patients aged 18 years or older, with a diagnosis of primary and/or secondary thyroid lymphoma. We will include reports of adult cases diagnosed with primary thyroid lymphoma or secondary thyroid lymphoma and exclude studies involving patients with primary or secondary tumors of an origin other than thyroid lymphoma. Additionally, studies reporting patients who, alongside primary or secondary thyroid lymphoma, have concomitant diseases associated with high morbidity or mortality will be excluded.
A total of two independent reviewers will participate in the screening, selection, and data extraction process, all of which will be carried out blindly. Conflicts between reviewers will be resolved through discussion or by involving an additional reviewer. Results will be reported using descriptive statistics, and the information will be stored in RedCap (Electronic Research Data Capture).

RESULTS

The literature search was conducted on August 9, 2024, using the following databases: LILACS, MEDLINE, and EMBASE, to identify observational studies. A total of 1,404 results were retrieved. The scoping review is expected to be completed by August 2025

CONCLUSIONS

This scoping review will describe the current understanding of the prognostic factors that influence the course of the disease in patients diagnosed with primary and secondary thyroid lymphoma. The review will highlight characteristics that may identify patients at risk of more aggressive disease behavior and could potentially guide therapeutic decisions. Future studies should assess the incidence of these prognostic factors across different age groups and explore their clinical correlations.

Authors: Faizal Michel , Parra Humberto , Romero Paula Andrea , Calderón María Fernanda , Bastidas María Fernanda , Aguilar Sofia
Published: February 2025

Mpox is caused by the monkeypox virus, a DNA virus of the Poxviridae family and the Orthopoxvirus genus. As far as its clinical presentation is concerned, symptoms such as fever, lymphadenopathy and maculopapular rash affecting mucosal tissues, palms and soles have been described. However, atypical presentations have been reported in patients with impaired immune functions. Men who have sex with men (MSM) are among the most affected populations and sexual contact is one of the main forms of transmission. It has been estimated that close to 28-51% of MSM infected with monkeypox virus have an associated human immunodeficiency virus infection. In this report, we describe the case of a patient with human immunodeficiency virus infection who acquired the Mpox and had an atypical clinical presentation and course. In conclusion, the current Mpox outbreak has differed from previous outbreaks in terms of clinical characteristics, transmission mode and population at risk. Immunosuppression is a risk factor for an atypical course, with longer duration and development of complications that lead to longer hospital stay and mortality.

Proprietary Costs of Financial Reporting, Country-Level Attributes, and Financial Statement Comparability
Authors: Gil Jangho , Gotti Giorgio , Sobngwi Christian K.
Published: February 2025

Previous studies indicate the existence of a negative relation between proprietary costs of financial reporting and financial statement comparability in the United States. However, this relation may vary depending on the strength of the financial reporting environment. Using four country-level latent factors suggested in Isidro, Nanda, and Wysocki (2020), this study investigates the impact of country-level attributes on the relation between proprietary costs of financial reporting and financial statement comparability. We find that the negative relation is stronger in countries with relatively poorer financial reporting environments. Furthermore, we find that strong protection of investor rights and better-developed capital markets are most effective in improving financial reporting quality, as evidenced by higher accounting comparability. This study provides guidance for standard setters in countries with poor financial reporting environments. Standard setters should emphasize strong protection of investor rights and further promote the development of capital markets to enhance firms’ financial reporting quality.

UNA LECTURA DERRIDIANA DE ALGO QUEMA (2018): EL MAL DE UN ARCHIVO FAMILIAR
Authors: Laguna-Tapia Andrés , Villena Belén
Published: February 2025

Este artículo propone una lectura derridiana del documental Algo Quema (2018) de Mauricio Alfredo Ovando, centrándose en la exploración que realiza la película de los archivos familiares y la compleja relación entre la memoria, la historia y la identidad. Al examinar la confrontación del cineasta con el controvertido pasado de su abuelo, Alfredo Ovando Candia, la película expone las tensiones entre las historias personales y las públicas. A través de una perspectiva deconstructiva, el artículo reflexiona sobre cómo la película emplea técnicas cinematográficas para interrogar la naturaleza del archivo. Algo Quema revela el archivo como un espacio dinámico y disputado donde los recuerdos se construyen y reconstruyen continuamente. La exploración de la película sobre el mal de archivo destaca el potencial destructivo y creativo de la memoria, así como las formas en que individuos y familias lidian con historias difíciles. Aplicando el concepto derridiano de phármakon, el artículo argumenta que la película funciona como una sustancia que opera de acuerdo a la dosis y a quien es inoculada. La capacidad de la película para abrir nuevas posibilidades de comprensión del pasado se ve atenuada por el doloroso proceso de confrontar eventos traumáticos. Propone que Algo Quema ofrece una reflexión sobre el papel de la memoria en la configuración de nuestras identidades, sobre las formas en las que el pasado continúa acechando el presente y al porvenir.

Published: February 2025

The article examines the current state of the diamond tool industry for processing decorative stones and provides a detailed analysis of its development prospects. An extensive review of numerous literature sources has established that the primary issues requiring immediate attention are the high cost of these tools and their limited service life. This high cost is primarily attributed to the expensive cobalt alloy powders used in their production. This problem is particularly acute for Ukrainian manufacturers, who have faced severe shortages and sharp increases in the cost of cobalt-based raw materials following Russia's full-scale invasion. Consequently, the article's primary focus is on establishing the scientific foundations necessary for developing alternative metal matrix compositions that can offer high performance while simultaneously reducing the overall cost of the final products. The study delves into the impact of various factors, including the chemical and phase composition of the metal matrix, the size and concentration of diamond grains, microstructure and surface topography, operating conditions, as well as the spectrographic and mineralogical properties of the processed material on the wear characteristics and durability of diamond tools. In addition, the article analyses modern manufacturing technologies for such tools, methodological approaches to studying their properties, and potential strategies for improving their operational characteristics. Based on the comprehensive review, several promising metal bond compositions based on iron alloys have been identified, and a series of experimental studies have been planned to address the identified challenges.

This work considers the actual problem of using composite reinforcement in building structures. Traditional steel fittings have some disadvantages, such as susceptibility to corrosion, heavy weight, and the need for frequent maintenance. Composite materials, unlike metals, are lighter, stronger, and less prone to corrosion, which increases the durability of structures and reduces operating costs. In the work, a structural analysis of the composite armature was carried out using modern microscopic methods, making it possible to identify certain structural defects. The ImageJ software package used in the study made it possible to conduct a detailed quantitative analysis of the structure of the composite armature. Thanks to the capabilities of automatic processing of microstructural images, ImageJ provided an accurate determination of the area of fibers, their diameters, and distribution in the material. This greatly simplified analyzing the composite structure and allowed for a more objective assessment of reinforcing quality. . The use of ImageJ made it possible to increase the accuracy of research and provided an opportunity to quickly process large volumes of data. In addition, the microhardness study showed a significant difference in hardness between the matrix and the reinforcing fibers, highlighting the anisotropy of the material properties. The authors recommend improving the mechanical properties of composite reinforcement due to the distribution of fibers in several directions. The use of composite materials is promising, especially in aggressive environments and with increased energy efficiency requirements.
Style refleksyjności edukacyjnej uczących się dorosłych w perspektywie biograficznej
Authors: Gola Wojciech
Published: February 2025

The article presents the results of the study Educational Pathways of Adult Learners in Poland. It presents a typology of six styles of educational reflexivity adopted by adults undertaking educational activity after completing initial education. The notion of educational reflexivity refers to Margaret Archer’s concept of reflexivity, understood as an immanent ability to shape the subject’s ways of acting in relation to external circumstances, which in the concept of the three-phase model of the subject-structure relationship points to reflexivity as a mediating mechanism between structure and the individual’s agency.

The typology was developed based on the analysis of narrative interviews on the topic of learning in adulthood. During the analysis of the narratives, analytical categories relating to the issue of reflexivity were adapted to the topic of learning and education. The developed typology of reflexivity styles reveals variation in learning strategies and attitudes towards educational activity in terms of the meaning given to education and learning, the dominant concerns and goals pursued by educational activity, the ways in which learning in adulthood is planned, engaged and decided upon, the preferred forms of learning, and the role and importance of the socio-biographical context.
Narracja o wydajności i bezbłędności versus naturalna potrzeba rozwoju i samorealizacji – pracownicy i ich przełożeni wobec otwartości na uczenie się w sektorze przemysłu chemicznego
Authors: Osowska Małgorzata
Published: February 2025

The article concerns the ways in which learning at work exists in the organizational cultures of companies belonging to the chemical industry sector. For this purpose, quantitative and qualitative data from employees and management staff were presented. The text informs how learning at work functions in the narratives of the sector’s staff, what goals and meanings are linked with it, what are the barriers to this practice, its preferred forms, and consequences.

The study under analysis allowed us to observe that learning perceived from the perspective of management and employees are two different worlds and the narratives describing them, which differ at the level of values, meanings and preferences. Employees generally have a need for continuous improvement, and for them learning is often synonymous not only with expanding competences, but also with general development and the ability to cope with various tasks. Meanwhile, management staff is more often focused on short-term goals related to proper handling of processes. They relatively rarely plan employee development and do not expect an attitude of readiness to learn. They base on the competences already possessed by employees, treating training as an intervention. They expect employees to be reliable in carrying out their tasks, which is inconsistent with learning - understood as facing new situations and the risk of making mistakes. The conclusions of the article signal the need to harmonize the perspectives of employees and management staff and further research on the determinants of their approaches to learning.

Published: February 2025

The article presents the Integrated Qualifications System (IQS), its origins, assumptions and significance for the state policy to support lifelong learning.

The first years of functioning of the IQS raise a number of questions, including those about the accuracy and completeness of the solutions introduced by the Act on the IQS and the consistency of actions taken by the state to encourage adults to acquire and confirm new competences. Many of them remain unanswered today. There is a lack of research from which one could obtain clear recommendations for practice. The text refers to strategic, European and national documents, available research reports, as well as scientific studies in which one can find premises justifying the intensification of state actions for lifelong learning.

Authors:   School of Public Health and Social Sciences, Muhimbili University of Health and Allied Sciences, Msunzaa Zephania Pascal , Kessy Anna Tengia , Bakar Saidah Mohamed
Published: February 2025

ABSTRACT
Background: Cervical cancer is the fourth most common cause of death among women of reproductive age (15-49 years). In Tanzania, cervical cancer is the first cause of mortality and morbidity among females with cancers. The disease impact is highly associated with a lack of adequate knowledge and a negative attitude toward cervical cancer screening among healthcare workers (HCWs).
This study aimed to assess knowledge and attitude toward cervical cancer screening among female students as future HCWs from allied health colleges in the Shinyanga region.
Method: Descriptive cross-sectional study data was collected from 420 students in allied health colleges using a self-administered questionnaire. Data were analyzed using Statistical Package for Social Sciences (SPSS) version 22, Likert, and brooms cut-off points. The association between cervical cancer screening and the independent variables on knowledge, attitude, and other related factors was established by using logistic regression, and the Odds Ratio (OR) of greater than one, 95% confidence interval, and a P-value of <.05 was statistically significant.
Results: Two-thirds of the respondents 276 (65.7%) had low knowledge, while only 34 (8.1%) had very good knowledge of cervical cancer and screening. Most of the respondents 298 (70.1%) had a favorable attitude toward cervical cancer screening. Only 52 (12.1%) had ever screened for cervical cancer. Logistic regression showed odds at 2.37 (95% CI, 1.30-4.31, p=.005) of taking the cervical screening test to students with the correct knowledge and positive attitude to cervical screening at 1.42 (95% CI, 0.32-6.29, p=.647)
Conclusion: The study showed there is low knowledge of cervical cancer screening among female students in health and allied colleges, despite a favorable attitude toward the practice of screening. A well-integrated approach to providing comprehensive and practical aspects of cervical cancer screening during formal training in the curriculum for female students should be adopted to increase their knowledge and positive attitude toward screening.

Authors:   Clinical Research Programme, Mwanza Research Centre, National Institute for Medical Research, Mwanza, Mwanza, Tanzania, Kunzia Happyness , Sanga Erica , Ngallaba Sospatro , PrayGod George
Published: February 2025

ABSTRACT
Introduction: Indoor Air Pollution (IAP) from biomass fuel is one of the major health threats globally. There is limited data on community awareness and perceptions of health conditions associated with IAP in urban informal settlements in sub-Saharan Africa. We explored community perceptions of IAP-associated health conditions, risk behaviors, and potential interventions to reduce IAP in urban informal settlements.
Methods: We used purposive sampling to recruit participants from households located in Mwanza urban informal settlements. We conducted 16 In-depth Interviews (IDIs), two Focused Group Discussions (FGDs), and four Key Informant Interviews (KIIs). Obtained data were then transcribed, translated, coded and analyzed thematically with Dedoose qualitative data analysis software.
Results: Majority of participants were unaware of the health conditions associated with IAP. Participants perceived biomass fuel from charcoal as a safe fuel compared to other known fuels (firewood and gas). Indoor biomass fuel use for cooking and use of rubber and plastic materials for fire lighting were the commonly practices and risk behaviors for IAP. Moreover, poverty is what guides the choice of fuel use for cooking.
Conclusion: Participants awareness health effects of biomass fuel was low, strategies to reduce poverty and health promotion on the health effects of IAP are urgently needed in the Mwanza urban informal settlements.
Healthcare-Associated Infections in a Tertiary Care Hospital: Significance of Patient Referral Practices
Authors:   University of Dar Es Salaam, Mbeya College of Health and Allied Sciences, Mbeya, Tanzania., Chuwa Agapiti H.
Published: February 2025

ABSTRACT
Introduction: Nosocomial infections, also known as healthcare-associated infections (HCAIs), are infections that a patient acquires while receiving healthcare services within 48 hours of admission to hospital. In high income countries, an average of 7% of hospitalised patients acquire a nosocomial infection. In low and middle income countries, however, prevalence rates can be as high as 30%. This is due to limited resources and supplies for infection control, inadequate training and lack of compliance with infection prevention and control regulations.
Methods: A cross-sectional, hospital based study was conducted among patients admitted to a tertiary care facility in Tanzania. A semi-structured questionnaire was used to collect information from 134 patients in different wards. Correlation and multivariate regression analyses were performed to determine the association between the independent variables, i.e. chronic illness, invasive procedures, use of antibiotics and referral status, and the dependent variable, i.e. new symptom, and their level of significance. The significance level was set at P≤ .05.
Results: A total of 134 patients participated in the study. Of the total number, 61% (n=82) of the patients were male and 43% (n=57) were referrals from other institutions. Fifteen percent (n=21) of the surveyed patients reported a new symptom. There was a positive correlation between referral status and invasive procedure with the occurrence of a new symptom. Multivariate analysis identified ‘referral status’ as an independent significant factor positively associated with healthcare-associated infetions (P=.041).
Conclusions: The results indicate a prevalence of 15.7% of healthcare-associated infections, which is unacceptably high for a tertiary care facility. Referral status was independently and significantly associated with HCAI. Improving patient referral patterns and hospital infection control can significantly reduce the risk of healthcare-associated infections.

ABSTRACT
Background: Heart failure (HF) is a chronic progressive condition in which the heart is unable to pump enough blood to meet the body’s need for blood and oxygen. Globally, about 64 million people are affected with HF. This study was undertaken to determine the magnitude and factors associated with potassium abnormalities in heart failure patients on diuretics in Tanzania.
Methods: This was a hospital based cross-sectional study conducted at Bugando Medical Centre’s outpatient clinic. The selection of this hospital was driven by the significant presence of heart failure patients in the facility and the convenience for the researchers, who were stationed at this facility during the study period. All consenting adult patients aged 18 years and above that were attending the cardiac clinic and had met Framingham criteria for heart failure and were taking diuretics for at least one month were included.
Results: The prevalence of hypokalemia and hyperkalemia was found to be 4.3% And 19.3% respectively. The median (IQR) age was 61 (46-70) years and majority of them (52.8%) were females. most of the patients (87.7%) had New York Heart Association (NYHA) class III heart failure.
Conclusion: Factors associated with potassium abnormalities include medication use, kidney disease and more severe heart failure. Healthcare providers should ensure that all patients with these associated factors receive regular electrolyte testing. Electrolytes should be part of the baseline investigation to all patients with heart failure starting treatment, and should be closely monitored in every clinic visit for early detection of these abnormalities and possible intervention, including dose adjustments.

Hugsandi skólastofa (e. thinking classroom) er kennslunálgun sem snýst um að skapa rými þar sem nemendur vinna saman að verkefnum sem eru hönnuð til að styðja nemendur við að öðlast skilning á nýjum hugtökum og hugmyndum með samræðum. Í þessari rannsókn var fylgst með kennslu eins stærðfræðikennara í íslenskum framhaldsskóla. Markmið rannsóknarinnar var að veita kennaranum endurgjöf á gæði eigin kennslu þegar kennt er eftir hugmyndafræði hugsandi skólastofu og veita innsýn í sjálfsrýni hans um niðurstöðurnar.
Gögnum var safnað með hljóðupptökum og áhorfi í þremur kennslustundum þar sem einum nemendahóp var fylgt eftir í eina kennsluviku. Gæði kennslunnar voru metin út frá greiningarrammanum PLATO fyrir yfirþættina faglegar kröfur (þ.e. samræður í skólastofunni og vitsmunaleg áskorun) og stigskiptan stuðning (þ.e. sýnikennsla, kennsla námsaðferða og endurgjöf). Helstu niðurstöður voru að í kennslustundunum voru faglegar kröfur almennt metnar á efri þrepum á meðan undirþættir stigskipts stuðnings voru metnir á bæði efri og neðri þrepum. Dæmi voru um sýnikennslu og kennslu námsaðferða á efsta þrepi, en endurgjöf var aldrei metin á efsta þrepi.

Efectos de la concentración laboral sobre los salarios en el sector de alta tecnología en México
Authors:   , Cadena Tinajero José Luis
Published: February 2025

En el marco de la teoría del monopsonio laboral, en este trabajo se analizan los efectos de la concentración en el mercado de trabajo sobre los salarios en la industria manufacturera mexicana de 2003 a 2018, con particular énfasis en el sector de alta tecnología. Para medir la concentración se construye el Índice Herfindahl-Hirschman para el empleo de las 86 ramas industriales. Se hace una radiografía del sector de alta tecnología en México y se exponen algunas características relevantes de por qué se asume que puede operar bajo las condiciones de un mercado laboral poco competitivo. Utilizando modelos en panel se explica el impacto que tiene la concentración laboral sobre los salarios; se controla por la tasa de subcontratación, por la productividad laboral y por el rezago de la variable dependiente, y se utilizan algunas variables asociadas al sesgo tecnológico como instrumentos para evitar endogeneidad. Se halla evidencia de que la concentración laboral es una variable estadísticamente significativa que afecta de manera negativa los salarios, y que la brecha en la desvinculación entre salarios y productividad se hace más grande cuando se controla por los efectos temporales de las remuneraciones.
Heterogeneidad estructural en la industria manufacturera: México, 1980-2023
Authors:   , Cedillo Zúñiga Nohemí
Published: February 2025

La presente investigación se centra en mostrar la heterogeneidad estructural en la industria manufacturera mexicana, la cual se ve acentuada por una apertura comercial acelerada respaldada por un marco de reformas que abogaban por la integración de la economía al mercado mundial. Se esperaba que esta integración incentivara el crecimiento del país a través de los intercambios comerciales internacionales. Asimismo, se esperaba que este nuevo orden mundial beneficiara a la industria al permitirle acceder a las cadenas globales de producción, no solo en términos de transferencia tecnológica, sino también en términos de desarrollo en las regiones por donde estas cadenas pasaban mediante un acoplamiento estratégico. Sin embargo, contrario a lo esperado, la industria manufacturera en México se segmentó, generando grupos que operan con dinámicas diferentes tanto en el mercado externo como en el interno. Esto se debe, en gran medida, a la integración a las cadenas globales de producción, que no solo resultó en un aumento de las exportaciones, sino también en un incremento en el consumo intermedio de insumos importados para la producción destinada al mercado nacional. Este fenómeno evidencia un proceso de desindustrialización prematura, acentuando la necesidad de tomar medidas adecuadas para abordar esta situación y promover un desarrollo económico sostenible.
Can social financing promote economic growth?—Empirical study based on the evidence of Fujian Province, China
Authors: Xue Jiashu , Li Wei
Published: February 2025

The role of social financing as a catalyst for financial growth, with potential to stimulate economic expansion, is a subject requiring further scrutiny and exploration. This study employs quarterly data from 2014 to 2023, encompassing social financing and economic growth patterns in both China and its Fujian Province. Through the construction of four OLS models and a VAR model, it has been determined that the extent of social financing within Fujian has a notable impact in enhancing regional economic growth, though the direct financing percentage proves to be insignificant. The research suggests that middle-income economies have the potential to increase their social financing scale. Relevant governmental bodies can facilitate economic progression by broadening enterprise financing avenues and altering the ratio of direct financing in social financing as per the actual requirements.
Subcutaneous tiletamine-zolazepam produces moderate sedation in red-eared sliders (Trachemys scripta elegans) regardless of injection site
Authors: Farris Katharine Hausmann , Collins Elijah J. , Mans Christoph , Doss Grayson A.
Published: February 2025

OBJECTIVE

To evaluate the efficacy of tiletamine-zolazepam (TZ) for sedation of red-eared sliders and to assess the effect of injection site location on sedation parameters.

METHODS

Over a 1-month trial period, healthy turtles obtained from a rescue were administered TZ (10 mg/kg, SC) in the forelimb (FL) or hind limb (HL) in a randomized, blinded crossover design in a laboratory setting. Heart rate; respiratory rate; neck, forelimb, and hind limb muscle tone; pelvic limb withdrawal reflex; jaw tone; cloacal tone; and feasibility of positioning for jugular venipuncture were evaluated. Flumazenil at 0.05 mg/kg was administered SC 45 minutes after TZ injection for recovery. Time to first effects, total sedation score, and time to recovery were recorded.

RESULTS

There was no significant difference in mean time to initial sedative effects between FL (11 ± 4 minutes) and HL (14 ± 6 minutes) treatments in the study population (n = 8 turtles). Six of 8 turtles (75%) and 5 of 8 turtles (63%) in the FL and HL treatments, respectively, developed decreased muscle tone. Simulated jugular venipuncture was successful in 7 of 8 turtles (88%) in both treatments, although additional restraint was required in 3 of 8 turtles (43%) in the HL group. There was no significant difference in total sedation score at any time point between treatments, and median heart rate across the sedative period was similar between treatment groups. Mean time to recovery was similar between treatments (FL, 135 ± 55 minutes; HL, 165 ± 45 minutes).

CONCLUSIONS

Tiletamine-zolazepam (10 mg/kg) produced moderate sedation of red-eared sliders. The location of SC TZ injection administration did not significantly affect sedation parameters in this species.

CLINICAL RELEVANCE

Subcutaneous TZ can be used for sedation of red-eared sliders in clinical practice to facilitate examination and blood collection in this species.

Introduction

In traumatic brain injury (TBI), direct information can be obtained about cerebral blood flow, brain tissue oxygenation and cerebral perfusion pressure values. More importantly, an idea about the changes in these measurements can be obtained with multidimensional monitoring and widely used monitoring methods.

Aim of the study

We aimed to evaluate the monitoring of critically ill children who were followed up in our pediatric intensive care unit (PICU) due to TBI.

Material and Method

Twenty-eight patients with head trauma who were followed up in our tertiary PICU between 2018 and 2020 were included in the study. Cerebral tissue oxygenation, optic nerve sheath diameter (ONSD), Glasgow coma score (GCS) and Glasgow Outcome Score (GOSE) values were obtained from retrospective file records and examined.

Results

Male gender was 71.4% (n=20). When we classified TBI according to GCS, 50% (n=14) had moderate TBI and 50% had severe TBI. On the first day in the poor prognosis group, ONSD and nICP were found to be higher than in the good prognosis group (for ONSD, p=0.01; and for nICP, p=0.004). On the second day of hospitalization, the ONSD and nICP were significantly higher in the poor prognosis group than in the good prognosis group (for ONSD p=0.002; and for nICP p= 0.001). Cerebral tissue oxygenation values measured on the first and second days decreased significantly on the second day in both the good and poor prognosis groups (p=0.03, 0.006). In the good prognosis group, a statistically significant decrease was found in ONSD and nICP measurements taken on the 2nd day compared to the measurements taken at the time of hospitalization (for ONSD p=0.004; for nICP p<0.001).

Conclusion

The aim of multidimensional follow-up in traumatic brain injury is to protect the brain from both primary and secondary damage; for this reason, it should be followed closely with multimonitoring methods that are possibly multidisciplinary.

Introduction

Understanding the association between risk factors and clinical outcomes of COVID-19 can lead to identifying suitable management strategies for reducing the mortality rate among maternal COVID-19 patients in the ICU.

Aim of the Study

This study aims to investigate the clinical outcomes and risk factors associated with pregnant and postpartum women diagnosed with COVID-19 and admitted to the intensive care unit (ICU) between May 2020 and September 2021.

Materials and Methods

This retrospective cohort study was conducted at the Universitas Indonesia Hospital. Secondary data was collected from the medical records to include all pregnant and postpartum women diagnosed with confirmed COVID-19 admitted to the hospital during the research period.

Results

The study included 113 patients and found that admission to the ICU, age, and gestational age significantly influenced clinical outcomes, with a mortality rate of 42.11% among ICU-admitted patients. Pre-existing comorbidities such as type-2 diabetes mellitus, congestive heart failure, and coronary artery disease were associated with ICU admission. Having at least one comorbidity was found to increase the mortality rate by six-fold.

Conclusions

The study emphasizes the importance of monitoring and evaluating maternal and fetal complications during COVID-19 infection, highlighting the need for multidisciplinary management involving intensivists, obstetricians, anesthesiologists, and infectious disease specialists. The findings underscore the significance of baseline health status in treatment planning and the potential for evidence-based interventions to improve maternal outcomes and pregnancy preservation. Further research is warranted to validate these results and enhance understanding of the underlying pathophysiology.
Future Rainfall Projections in Vietnam based on a CMIP6 Dynamical Downscaling Experiment
Authors: Duc Thanh Ngo , Long Trinh Tuan
Published: February 2025

This study presents, for the first time, the dynamical downscaled results at 25 km resolution for Vietnam from a global climate model participating in the Coupled Model Intercomparison Project Phase 6. The regional climate model (RegCM) version 4.7 was used with initial and boundary conditions from the global model CNRM-CM6-1 (referred to as CNRM) under the two Shared Socioeconomic Pathways (SSPs) 2-4.5 and 5-8.5. Simulated rainfall from RegCM and CNRM for the baseline period 1995–2014 is compared with the observation-based Vietnam Gridded Precipitation Dataset. The results indicate that downscaling is particularly effective in complex terrain areas, notably in the Central region during the winter monsoon season. However, in an overall assessment, the downscaled RegCM rainfall has not demonstrated added value compared to the CNRM results, whether in terms of annual variation, rainfall amounts, or spatial distribution. Future projection results until the end of the 21st century show an increase in average rainfall, rainfall intensity, and annual maximum daily rainfall in Vietnam under both SSP2-4.5 and SSP5-8.5 scenarios. The increase is projected to reach approximately 25% in the Northern coastal area in the RegCM experiment under SSP5-8.5. The increase in rainfall intensity is pronounced across most of Vietnam, particularly under SSP5-8.5. Regarding projected maximum daily rainfall, there are discrepancies between the regional climate model and the global model. While CNRM exhibits unclear trends in many areas, RegCM indicates an overall increase in maximum daily rainfall across most of Vietnam under both SSPs scenarios.
Manipulative techniques in the US Political media discourse on the example of the election debates by D. Vance and T. Waltz
Authors: Lugovskikh Kirill Maksimovich
Published: February 2025

The article highlights the problems of political discourse, saturated with manipulative techniques that prevail especially in the media space and vividly illustrate the various manipulations of public consciousness in pre-election debates. The purpose of the study is to identify the means of manipulative techniques implemented in the US political media discourse. The material of the analysis is the debates of D. Vance and T. Waltz, which were held in the summer of 2024 and which are an actual example of the clash of two different positions on current and important issues related to US domestic and foreign policy. The real debate caused a great resonance among political scientists and the public due to the expertise and experience of D. Vance and T. Waltz, who, representing different points of view, stimulated a keen discussion of the debate in the media space.  The methodological basis is the work of A. P. Chudinov, E. I. Sheigal, J. S. Altynbekova in the field of political discourse, as well as the ideas of A. N. Glushchenko, E. L. Dotsenko, O. C. Issers on issues of manipulative techniques in media discourse. It has been established that in American media discourse, speech manipulation often uses means of expression, such as political metaphors, hyperbole, allusions and comparisons, as well as various types of comic, which indicates the importance in the socio-cultural space of the linguistic aspect, which embodies the ideological objectives of political leaders. The novelty of the research lies in the results obtained, which give an idea of modern strategies and tactics of political communication used to achieve an effective translocative effect. Conclusions are drawn about the patterns of language development and change, and its dynamics in political rhetoric, which are a multifaceted process that includes various aspects of linguistics, sociology, and political science. In addition, language, as a means of communication, is a powerful tool of influence in the political media space.

Published: February 2025

The incorporation of a drooping leading-edge wing optimizes the aerodynamic efficiency of aircraft under different flight conditions. The optimal positioning of leading-edge stringers for the cruise condition was determined in this study through the optimization of equivalent stress in fluid–structure coupling. This optimization significantly improved the load-carrying capacity of the leading edge during flight. The optimization significantly enhanced the load-carrying capacity of the leading edge during flight. The suitability of four configurations of the Watt-I six-bar mechanism in the skeletal structure of leading-edge droop (LD) was further evaluated. The establishment of a unified kinematic equation was followed by the utilization of genetic algorithms to optimize the mechanism parameters. The simulation results from the rigid–flexible coupling analysis demonstrate that the dual-drive-point mechanism exhibits minimal deviation in the airfoil curve. The aerodynamic analyses of various drogue angles also demonstrated a significant improvement in the aerodynamic performance of the drooping leading-edge airfoil compared to the standard airfoil. The variable camber leading-edge mechanism underwent numerical simulation validation before its fabrication as an experimental prototype, followed by the completion of deformation drive and static stiffness tests.
Optimization Approach for Long-Lifetime Orbits Around Planetary Moons
Authors: Lu Pengfei , Wang Yue
Published: February 2025

High-inclination orbits around planetary moons often suffer from short lifetimes due to multiple perturbations. This paper proposes a novel methodology to achieve long-lifetime, high-inclination orbits around planetary moons. The methodology is based on the doubly averaged dynamics considering the nonspherical gravity of the moon and the third-body perturbation from the planet. A semi-analytical formulation for the estimated orbital lifetime is developed. With the maximization of the orbital lifetime as the objective, a nonlinear programming model is established and solved to obtain optimal initial conditions. Then, a numerical scheme, which is based on the golden-section search and the differential correction, is proposed to map the obtained initial conditions back to the unaveraged system, i.e., to the osculating elements. The effectiveness of the proposed methodology is demonstrated through its application to orbit design around several different planetary moons, and the underlying mechanism enabling long-lifetime orbits is also revealed. Results prove that the initial conditions yielding the longest orbital lifetimes reside on stable manifolds of equilibrium points, i.e., the frozen orbits. Moreover, some comparisons indicate that the proposed methodology can obtain significantly extended orbital lifetimes compared to those reported in prior studies.
