Authors: Seo Beom , Park Chul , Rahman Md , Jeong Inseong , Kim Namsoo
Published: October 2024

Objective: This study aimed to evaluate the prevalence of cranial cruciate ligament rupture (RCCL) and the efficacy of tibial plateau angle (TPA) as a prognostic indicator in small breed dogs diagnosed with RCCL.
Materials and Methods: For this study, 53 dogs with RCCL were selected based on their medical data. The Tibial plateau angle (TPA) was calculated by analyzing the radiographic images of the stifle joint region. The dogs were categorized based on their body weight, sex, age, breed, and RCCL. Subsequently, clinical outcomes of dogs were evaluated based on their pre- and postoper¬ative TPAs.
Results: The prevalence of RCCL was higher in neutered dogs, especially those neutered before 6 months of age. The preoperative TPAs of all dogs diagnosed with RCCL were lowered with TPLO. Preoperative walking time in the higher pre-operative TPA (>25°) group (13.58 ± 1.53 days) was significantly (p < 0.05) longer than the lower pre-operative TPA (≤25°) group (10.09 ± 0.84). The lower pre-operative TPA (≤ 25°) group showed better prognoses without any more complications than the higher pre-operative TPA (> 25°) group. Furthermore, post-operative walking time in the higher post-operative TPA dogs (>10°) group (18.08 ± 2.22 days) was significantly (p < 0.05) longer than the lower post-operative TPA dogs (≤10°) group (10.20 ± 0.90 days). Likewise, the TPA (≤10°) group showed better prognoses with lowered complications.
Conclusion: Therefore, pre- and post-operative TPA plays an important prognostic factor, and post-operative TPA should be kept at<10° to get better clinical outcomes.

Published: October 2024

Antimicrobials are employed in the control of contagious illnesses in humans and animals and are also utilized as growth enhancers in livestock and poultry. Improper application of antibiotics results in the development of multi-drug-resistant (MDR) bacteria, such as methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant S. aureus (VRSA), colistin-resistant, extend¬ed-spectrum beta-lactamase (ESBL)-producing E. coli, and fluoroquinolone-resistant Salmonella. Transmission of MDR bacteria happens among animals, from human to animal, and vice versa, resulting in treatment failure, increased treatment cost, and high morality. In this article, we analyzed the recent publications of the current antimicrobial application practices in livestock and poultry farms and the development of antimicrobial resistant (AMR) bacteria in livestock and poultry and its adverse effects on human and animal health using PubMed, Google Scholar, and Google. Citations from published articles were also analyzed. Several drug-resistant bacteria, including MRSA, VRSA, colistin-resistant strains, ESBL-producing E. coli, and fluoroquinolone-resis¬tant Salmonella, have emerged due to heavy antibiotic application in cattle and poultry, according to the analysis. Transmission happens between people and animals as well as throughout the production chain, which raises the chance of failure of antibiotic therapy and fatality. To stop the proliferation of drug-resistant bacteria, it is important to ensure the proper use of antibiot¬ics in livestock and poultry. Especially in developing nations, strict control and implementation of antimicrobial rules are necessary. To successfully address antimicrobial resistance and lessen dependency on antibiotics, alternative disease management strategies in livestock and poultry must be developed.
Allah sebagai Ibu bagi Semua yang Berdosa
Authors: Elis Elis Timang , Agustinus Agustinus
Published: November 2024

Gambaran Allah sebagai Ibu dalam Alkitab merupakan topik yang sangat menarik untuk dikaji secara mendalam. Dalam konteks Alkitab yang berlatar belakang patriarki, gambaran yang sering digunakan dalam memahami Allah adalah “Bapa.” Allah selalu disebut sebagai Bapa, bahkan dalam peran-Nya sebagai Bapa bagi anak-anak-Nya, bukan Ibu. Pandangan tersebut cukup berdampak terhadap cara pandang umat percaya terhadap Allah hingga saat ini, yang melihat Allah sebagai Bapa, dikenal serta disapa hanya sebagai Bapa. Karena hal itulah, penelitian ini bertujuan untuk mengeksplorasi penyingkapan sisi keibuan Allah melalui narasi Kitab Kejadian pasal 3:1-24, yang berangkat dari perspektif feminis untuk melihat Allah dari sudut pandang sebagai Ibu. Dengan menggunakan pendekatan kajian biblika dan analisis teks secara hermeneutis, penelitian ini berupaya untuk mengungkapkan gambaran Allah sebagai Ibu, serta implikasinya bagi pemahaman teologis dalam konteks kekinian. Melalui analisis mendalam, penelitian ini mengidentifikasi adanya beberapa elemen yang mencerminkan sisi keibuan Allah. Elemen-elemen ini di antaranya adalah kasih dan perhatian Allah yang besar terhadap manusia, disiplin dan teguran yang diberikan, serta janji dan harapan yang ditawarkan. Gambaran Allah sebagai Ibu ini, memberikan perspektif baru dalam memahami karakter dan sifat Allah yang tidak hanya sebagai Bapa, tetapi juga sebagai Ibu yang penuh belas kasih, mendisiplinkan, serta penuh dengan kemurahan dan pengampunan.

Необходимость обеспечения прорывного роста производительности труда во всех секторах экономики стала одной из национальных задач государства. Для достижения стратегических целей, поставленных Президентом Российской Федерации, необходима качественная информация об уровне производительности труда и влияющих факторах. В статье обоснована необходимость совершенствования методик измерения производительности труда в различных сферах экономической деятельности, не затрагиваемых в нормативно утвержденных документах. Для оценки уровня производительности труда в банковском секторе экономики автором предложено применение комплексного подхода, основанного на использовании нескольких показателей, рассчитанных на основе отношения чистой прибыли и активов банка к численности персонала. Применение традиционных показателей на макроуровне дает возможность обеспечить сопоставление уровня производительности труда в банковской сфере. По результатам исследования установлено, что группировки банков по уровню производительности труда, рассчитанного по предлагаемым методикам, имеют схожие результаты, наибольшее количество банков вошли в первые две группы. Комплексная оценка дает возможность исключить недостатки применения простых методик, основанных только на одном показателе, а также позволяет получить наиболее достоверные данные об уровне производительности труда в банках.

The need to ensure breakthrough labor productivity growth in all sectors of the economy has become one of the national tasks of the state. In order to achieve the strategic goals set by the President of the Russian Federation, high-quality information on the level of labor productivity and influencing factors is needed. The article substantiates the need to improve the methods of measuring labor productivity in various fields of economic activity that are not covered in regulatory documents. To assess the level of labor productivity in the banking sector of the economy, the author proposes the application of an integrated approach based on the use of several indicators calculated on the basis of the ratio of net profit and assets of the bank to the number of staff. The use of traditional indicators at the macro level makes it possible to compare the level of labor productivity in the banking sector. According to the results of the study, it was found that groups of banks in terms of labor productivity calculated according to the proposed methods have similar results, the largest number of banks entered the first two groups. A comprehensive assessment makes it possible to eliminate the disadvantages of using simple methods based on only one indicator, and also allows you to obtain the most reliable data on the level of labor productivity in banks.

Clinical prediction scores predicting weaning failure from invasive mechanical ventilation: Role and limitations
Authors: Gupta Anish , Singh Omender , Juneja Deven
Published: October 2024

Invasive mechanical ventilation (IMV) has become integral to modern-day critical care. Even though critically ill patients frequently require IMV support, weaning from IMV remains an arduous task, with the reported weaning failure (WF) rates being as high as 50%. Optimizing the timing for weaning may aid in reducing time spent on the ventilator, associated adverse effects, patient discomfort, and medical care costs. Since weaning is a complex process and WF is often multi-factorial, several weaning scores have been developed to predict WF and aid decision-making. These scores are based on the patient's physiological and ventilatory parameters, but each has limitations. This review highlights the current role and limitations of the various clinical prediction scores available to predict WF.

Published: October 2024

BACKGROUND

Seizures are one of the most common neurological complications encountered in the intensive care unit (ICU). They can occur in the background of exacerbation of a known neurological disease or secondary to non-neurological conditions such as sepsis and metabolic disturbances. However, there is a paucity of literature on the incidence and pattern of new-onset seizures in ICUs.

AIM

To study the incidence and patterns of new-onset seizures in patients admitted to the medical ICU.

METHODS

This was a prospective, multicenter, observational study performed in two tertiary care centers in Hyderabad, India over a period of 1 year. Patients upon ICU admission, who developed new-onset generalized tonic clonic seizures (GTCS), were enrolled. Those with a pre-existing seizure disorder, acute cerebrovascular accident, head injury, known structural brain lesions, or chronic liver disease were excluded as they have a higher likelihood of developing seizures. All enrolled patients were subjected to biochemical routines, radiological imaging of either computed tomography or magnetic resonance imaging, and other relevant laboratory tests as per clinical suspicion according to the protocol, and their data were recorded. Statistical analyses were conducted using descriptive statistics, χ 2 tests, and linear regression.

RESULTS

A total of 61 of 2522 patients developed GTCS. Among all etiologies of seizures, metabolic causes were most frequent (35%) followed by infective causes (27%) and others (new-onset structural, drug withdrawal, drug-induced, toxicology-related, and miscellaneous factors). Logistic regression analysis showed that increased sodium and calcium levels were associated with a lower likelihood of developing seizures.

CONCLUSION

This study identified the etiology of new-onset seizures developing in critically ill patients admitted to the ICU. These findings highlight the need for targeted monitoring of those at risk of developing seizures.
Predicting the risk of mortality in children with dengue-induced hepatitis admitted to the paediatric intensive care unit
Authors: Nguyen Thanh Tat , Ngo Phuong Thi-Mai , Vo Luan Thanh
Published: October 2024

BACKGROUND

Dengue-associated acute liver failure (PALF) accounts for a high mortality rate in children admitted to the pediatric intensive care unit (PICU). To date, there is a lack of data on clinical algorithms for estimating the risk of mortality in pediatric patients with dengue-induced severe hepatitis (DISH).

AIM

To determine the prevalence of PALF and identify the predictors of mortality among patients with DISH.

METHODS

This single-institution retrospective study was performed at a tertiary pediatric hospital in Vietnam between 2013 and 2022. The primary outcome was in-hospital mortality in pediatric patients with DISH, which was defined as either aspartate aminotransferase > 350 IU/L or alanine aminotransferase > 400 IU/L. Prognostic models for estimating the risk of death among patients with DISH were developed using a predefined set of clinical covariables and hepatic biomarkers on PICU admission and during the first 72 hours of admission. Area under the curve, multivariable logistic regression, and multiple imputation using the chained equation for missing values were performed. Backward stepwise model selection based on the Akaike information criterion was employed. Bootstrapping, calibration slope, and Brier score were used to assess the final models.

RESULTS

A total of 459 children with DISH were included in the analysis. The median patient age was 7.7 years (interquartile range: 4.3-10.1 years). The prevalence of dengue-associated PALF in children with DISH was 18.3%. Thirty-nine DISH patients developing PALF (8.5%) died. Hepatic biomarkers, including the international normalized ratio (INR) ≥ 2.11 and total serum bilirubin (≥ 1.7 mg/dL), showed high predictive values for mortality (all P values < 0.001). Multivariable models showed the significant clinical predictors of death from dengue-induced PALF in patients with DISH, including reduced level of consciousness (pain and unresponsive levels on the Alert, Verbal, Pain, Unresponsive scale), high vasoactive-inotropic score (> 30), and elevated levels of blood lactate, INR, and serum bilirubin. The final prognostic model demonstrated high discrimination, Brier score, and an acceptable calibration slope.

CONCLUSION

The prevalence of PALF in children with DISH is 18.3%. We developed robust prognostic models to estimate the risk of death in hospitalized children with severe dengue-induced hepatitis.

Published: October 2024

BACKGROUND

Pulmonary hypertension (PH) is a progressive disease characterized by endothelial dysfunction and vascular remodeling and is a leading cause of mortality worldwide. Although it is independently associated with multiple comorbidities, the impact of diabetes mellitus (DM) on mortality in patients with PH remains uncertain. To address this issue, we conducted a systematic review and meta-analysis to investigate the effect of DM on survival in patients with pulmonary hypertension.

AIM

To investigate the impact of diabetes mellitus on mortality in pulmonary hypertension patients.

METHODS

We conducted a comprehensive search of four major electronic bibliographic databases like PubMed, Google Scholar, Scopus, and Embase, and identified 106 relevant studies, out of 1561 articles, published since the year 2000 for full-text review. Fourteen retrospective and prospective cohort studies that compared survival between patients with DM and those without DM in the context of PH were deemed eligible for inclusion in our meta-analysis. The study was registered on PROSPERO with the identifier CRD42023390232.

RESULTS

A total of 116455 patients with PH were included in the meta-analysis, of whom 41228 suffered from DM and 75227 did not. The results of our meta-analysis indicate an elevated mortality rate among PH patients with diabetes mellitus in comparison to those without DM [odds ratio (OR) = 1.40, 95%CI: 1.15–1.70, P = 0.0006]. The meta-regression analysis unveiled a statistically significant negative association between mean age and effect size (coefficient = -0.036, P value = 0.018). Conversely, a statistically significant positive association was detected between female proportion and effect size (coefficient = 0.000, P value < 0.001).

CONCLUSION

Our meta-analysis, which included approximately 116500 PH patients, revealed that the presence of diabetes mellitus was associated with increased odds of mortality when compared to non-diabetic patients. The meta-regression analysis indicates that studies with older participants and lower proportions of females tend to exhibit smaller effect sizes. Clinically, these findings underscore the importance of incorporating diabetes status into the risk stratification of patients with PH with more aggressive monitoring and early intervention to improve prognosis potentially.

Combinatorial proof of Girard-Waring formula
Authors: Łukasz Bożyk
Published: November 2024

\noindent The well-known and celebrated identity of Girard (1629) and Waring (1762) states that
\[x^n+y^n=\sum_{m=0}^{\lfloor n/2\rfloor}(-1)^m\frac{n}{n-m}\binom{n-m}{m}\left(xy\right)^m\left(x+y\right)^{n-2m}\]
and can be easily proven algebraically (see H.W. Gould, The Girard--Waring power sum formulas for symmetric functions and Fibonacci sequences,} Fibonacci Quart. 37 (1999), no. 2, 135--140). In this note, we provide a combinatorial proof of this identity.

Authors: Rashedi Sahar , Rashedi Muhammed Eshaq , Karakoyun Murat
Published: October 2024

The best solution found for a problem under specific circumstances is called optimization. Algorithms for optimization can make the best use of the information at their disposal. Numerous optimization algorithms have been created thus far by researchers, and most of these algorithms are based on the characteristics of naturally occurring biological organisms. Optimization algorithms have proven to be highly effective in numerous fields, including finance, engineering, and medical. Apart from these applications, they have also been employed in data mining techniques including clustering and classification. In many different domains, the clustering method is widely applied. Finding the optimum cluster centers is the most crucial step in the clustering process. In this study, the Artificial Algae Algorithm (AAA) is used to perform the clustering procedure by using 12 datasets that were taken from the UCI Machine Learning Repository. For every dataset, the squared distance values between the cluster centers and the data were computed in order to assess the effectiveness of AAA. The study evaluated AAA's performance against that of the ALO, DEA, MFO, PSO, TSA, and WOA algorithms. The clustering performance of AAA on benchmark datasets was measured to be better than the performance of other algorithms.
An Examination of Calculations: From Anaerobic Mono-digestion to Co-digestion
Authors: Yuen Pong Kau , Lau Cheng Man Diana , Yuen Kuok In Gabriel
Published: November 2024

Anaerobic digestion is a biochemical process and form of sustainable technology. In comparison to mono-digestion, co-digestion is more effective in the utilization of diverse resources, supply of nutrient balance, and overall digestibility and stability. The co-digestion biodegradability index, co-digestion performance index, and synergistic effect index are generally used as anaerobic metrics to evaluate the co-digestion performance. Although they are numerical parameters, little information on their working procedures has been revealed. There is also a lack of supporting calculations for some published data hence their values cannot be verified. The aim of this article is to reconsider and examine the mathematical calculations from anaerobic mono-digestion to co-digestion. The method of study is a pen-and-paper analysis that processes both experimental and theoretical data from past studies. The article serves four purposes. First, it identifies processing parameters. Second, it shows step-by-step procedures of a series of calculations. Third, it identifies the core parameter in the calculation of anaerobic co-digestion. Fourth, it establishes the relationships between co-digestion biodegradability index, co-digestion performance index, and synergistic effect index. Critically, the mass fraction of volatile solid is identified as the core parameter that determines the valid calculations of co-digestion.

Multilayer packaging is one of the fastest growing areas. The reason for the high proportion of multilayer packaging is that the combination of different materials allows the creation of materials with individual properties at low material consumption. Nowadays, multilayer packaging is used to package many different products, especially food products such as meat, vegetables, milk and its derivatives, juices, as well as cleaning products and medical equipment. Most recycling and recovery of post-consumer plastic waste occurs in four ways: primary mechanical recycling (re-extrusion or closed-loop recycling) of waste into a similar product, secondary (mechanical) recycling into products with lower properties, tertiary chemical recovery of components, and quaternary energy recovery by combustion. Since in many cases the different polymers/materials are not mixed, such packaging is generally not subject to primary mechanical recycling. Further technology development is needed to more efficiently collect, sort, separate and recycle these multi-layer packaging materials as they represent a growing amount of post-consumer and post-industrial plastic waste. This review article discusses multilayer polymer materials, which include polyethylene, polyethylene terephthalate, cellulose, aluminum, polyamide, etc., as well as methods for processing multilayer polymer packaging such as mechanical recycling, the process of recovery and deposition using solvent (STRAP), production of APPW/EG composites for 3D printing, use of multilayer packaging as a raw material for the extraction of cellulose nanocrystals, etc.

The paper shows how the mechanical and physical properties of a wood-polymer composite panel play a crucial role in determining the suitability of products for various applications. Recent advances in catalytic polymerization technologies of polyolefin resins and process technologies have made wood-polymer composites (WPC) a material widely used in various industrial applications. The key mechanical properties such as strength and stiffness of composites have average values with respect to those of polymers and wood. The morphology of the structure plays an important role in determining most of the functional attributes of WPC. The moisture resistance of polymers compared to wood is directly related to the molecular structure of the plastic used. The development of mechanically robust and maintenance-free WPCs will both contribute to the economic growth of the wood and chemical industries and provide new opportunities for end users. The list of WPCs is very broad and covers different types of polymer matrices, fillers and innovative additives. The final optimization of WPCs requires an understanding of the material characteristics and a comprehensive evaluation of its mechanical properties. The paper presents a mathematical model of the heat conduction process taking into account the strength characteristics of a three-layer wood-polymer composite panel depending on the intended use of the product.

Se utilizó un enfoque comparativo para evaluar cómo las políticas contracíclicas y la diversificación económica impactaron la capacidad de recuperación de Brasil, Chile, Ecuador y Argentina. Se recopilaron datos históricos sobre el crecimiento del PIB para identificar patrones de recuperación tras crisis significativas. Los resultados muestran que Brasil y Chile, con economías más diversificadas, demostraron una recuperación más rápida y sostenida en comparación con Ecuador y Argentina, donde la dependencia de las materias primas prolongó los periodos de recesión. El estudio concluye que la diversificación económica y la implementación de políticas adecuadas son fundamentales para fortalecer la resiliencia económica. Los ciclos económicos fueron utilizados para identificar las fases de contracción y recuperación, proporcionando una visión integral del proceso de adaptación económica. Este análisis tiene implicaciones significativas para la formulación de políticas que promuevan una mayor estabilidad económica y una capacidad adaptativa mejorada en la región.

El estudio aborda la transformación educativa impulsada por la inteligencia artificial (IA) y los desafíos asociados a su implementación en el contexto académico. El objetivo principal es analizar los beneficios, riesgos y consideraciones éticas en la adopción de IA en la educación, mediante una revisión bibliográfica exhaustiva de estudios recientes y reportes de organismos internacionales. La metodología empleada fue de tipo exploratoria, basada en una revisión de literatura en bases de datos académicas y fuentes relevantes sobre IA y educación. Los resultados destacan que la IA permite personalizar el aprendizaje, automatizar tareas administrativas y optimizar la retroalimentación en tiempo real; sin embargo, plantea también problemas éticos en términos de privacidad de datos y sesgo algorítmico, así como desigualdades derivadas de la brecha digital. La discusión sugiere que, si bien la IA ofrece oportunidades para mejorar la calidad educativa, su integración debe gestionarse cuidadosamente para evitar desigualdades y proteger la autonomía estudiantil. Como conclusión, el estudio subraya la importancia de políticas inclusivas, inversión en infraestructura y capacitación docente para asegurar que la IA actúe como un complemento educativo, promoviendo una educación ética y accesible para todos.

Os desafios da inclusão, acolhimento e ensino da língua para estudantes imigrantes no Brasil
Authors: Fabiano Maria Lucia Alves , Bógus Lucia Maria Machado
Published: November 2024

O presente trabalho discute as condições para a inclusão, adaptação e a participação social da criança imigrante nas escolas brasileiras. O estudo baseia-se em revisão de literatura, legislação migratória, fontes documentais e registros administrativos que possibilitam a combinação de dados para analisar aspectos importantes do cotidiano da criança imigrante, em sua vivência no ambiente escolar. Objetiva, também, refletir como ocorre o processo de inclusão deste grupo, apontando os desafios que enfrenta, com destaque para a barreira da língua. O estudo possibilitou perceber que no interior da escola os processos de interação e de aprendizagem da criança imigrante são conturbados; contudo, sua adaptação e desenvolvimento é, na maioria das vezes, satisfatória, o que leva a indagar sobre a importância dos instrumentos pedagógicos utilizados por professores e outros agentes educacionais O maior desafio apontado pelo estudo é a necessidade de compreender que o processo de inclusão da criança imigrante no ambiente escolar, no Brasil, vincula-se à ausência de um projeto mais amplo que assegure sua inserção e minimize a discriminação e o preconceito, ainda muito presentes na sociedade brasileira e, por extensão, no interior da própria escola.
How Can Midwives Prevent Birth Trauma?
Authors: Conrad-Hale Lucy
Published: November 2024

Recently qualifying as a midwife and having various conversations with colleagues and families has reiterated the common misconception that birth trauma is something we can diagnose from simply reading a delivery summary. The notion that birth trauma exclusively happens when an emergency buzzer is pulled, or when the total blood loss ticks over 500mls disregards the impact that our care has on women’s experience, be it positive or negative. With this in mind, the objective of this article is to unpack what we can do as midwives to prevent women being traumatised by their birth experiences.
