PREDICTING PATIENT OUTCOMES USING ONE-HOUR ADULT EARLY WARNING SCORE (AEWS)
Authors: WAHEED A , SHAH MI , MALIK A , KAMAL H , SAQIB HW , KHAN AS
Published: October 2024

Early Warning Scores (EWS) are widely utilized tools to predict patient outcomes, particularly in critical care settings and emergency departments (ED). However, while Adult Early Warning Scores (AEWS) have been employed for general patient outcome prediction, the specific utility of a one-hour AEWS in the ED has not been thoroughly explored. Accurate early prediction of patient disposition could enhance clinical decision-making, resource allocation, and patient safety. Objective: This study aims to evaluate the effectiveness of one-hour Adult Early Warning Scores (AEWS) in predicting patient disposition (discharge, floor admission, or ICU admission) in the emergency department. Methods: A prospective observational study was conducted on 227 patients aged 16 years and above who presented to the ED of Shifa International Hospital, Islamabad, from January 2024 to June 2024. Vital signs, including heart rate, respiratory rate, blood pressure, oxygen saturation, and temperature, were recorded at the one-hour mark post-admission, and the one-hour AEWS was calculated. Patient outcomes were categorized into three groups: discharge, admission to the general floor, or admission to the ICU. Logistic regression was used to determine the relationship between one-hour AEWS and patient disposition. Receiver Operating Characteristic (ROC) curve analysis was performed to assess the predictive power of the AEWS for determining patient outcomes. Results: There was a statistically significant correlation between the one-hour AEWS and patient disposition (p<0.001). The ROC curve analysis showed an Area Under the Curve (AUC) of 0.753, demonstrating good predictive accuracy. A cutoff AEWS value of 2.5 was identified, with patients scoring below this threshold being more likely to be discharged, while those scoring above 2.5 were more likely to require hospital admission or ICU care. The sensitivity and specificity of AEWS at this cutoff were 71% and 68%, respectively. Conclusion: The one-hour AEWS has proven to be a valuable tool in predicting patient disposition in the emergency department. Its ability to distinguish between patients who can be safely discharged and those requiring further care highlights its potential utility in improving patient triage, optimizing resource use, and enhancing clinical decision-making. Further multicenter studies are needed to validate these findings and assess the integration of AEWS into routine ED practice.

Authors: Khikani Ali Nadhim , Firat Müge , Al-Khafaji Zaytoon Abdulrida
Published: October 2024

Background: HCMV is a prevalent virus that affects a significant section of the human population, causes severe disease, and affects the fetus in pregnant women. hcmv-miRNAs are important regulatory molecules in miscarriages in women CMV-infected. Objective: To evaluate the association of hcmv-miR-UL36-5P gene expression with miscarriages in women with HCMV. Methods: A case-control study was designed to include 140 women who had miscarriages at random, and 50 of them who had miscarriages with a high CMV viral load were categorized as miscarriage groups. Additionally, 50 healthy pregnant women who had not previously experienced miscarriages were included as a control group. After diagnosis of HCMV IgM and IgG via the VIDAS assay and CMV viral load detected by qPCR, RNA was extracted from blood samples to measure the hcmv-miR-UL36-5P gene expression by qPCR technique. Results: The results revealed that out of 140 women with miscarriages, 50(35.7%) were seropositive for CMV, while 90(64.3%) were seronegative for CMV, and show that only 3(6.0%) samples were seropositive to CMV IgM, 8(16.0%) seropositive for both CMV IgM and IgG, and 39(78.0%) were seropositive for CMV IgG. The expression of hcmv-miR-UL36-5P in miscarriage women was 3.11-fold higher than the control group. Conclusions: Upregulated expression of the hcmv-miR-UL36-5P gene in women with miscarriage confirms its role in miscarriage. These miRNAs may contribute to the pathogenesis of HCMV infection and its involvement in pregnancy complications.

Published: October 2024

The substantial use of medicinal plants in traditional poultry farming is a well-established practice. The present study aimed to determine the median lethal dose (LD50) of ethanolic extracts of Jatropha multifida and Hyptis suaveolens in local chickens and to assess the effects of these extracts on feed intake, water intake, and average body weight. The methodology followed OECD Directive 223, which involves administering the highest dose of the extract to the chickens and assessing any mortality. Three homogeneous groups of five chickens each were formed for the limit dose test. The control group received distilled water, while batches 1 and 2 received 700 mg of ethanolic extract of J. multifida and H. suaveolens, respectively. The average body weight of the chickens was 350g ± 20, and the extracts were administered via gavage at a suspension of 2000 mg/kg.bwt of the extract dissolved in water. The results of the phytochemical tests indicated the presence of several chemical compounds known for their therapeutic effects. The productivity of the extract was 2.75 ± 0.19 for J. multifida and 3.3 ± 0.27 for H. suaveolens. After administration of the suspensions, observation for 14 days revealed no mortality. This finding indicated that the LD50 of the utilized ethanolic extracts exceeds the limit dose (2000 mg/kg.bwt). However, feed intake (49 ± 3 > 46±4) and average body weight (436 ± 31 > 388 ± 37) in batch 2 were significantly higher than those in batch 1. Future research should explore the subacute toxicity of J. multifida and H. suaveolens across various chicken breeds.

The Gaga chicken is an indigenous Indonesian breed that is important to preserve using semen cryopreservation technology. The study was conducted to determine the effect of adding sorbitol and butylated hydroxytoluene (BHT) in the diluent on the structural and surface ultrastructure of cryopreserved Gaga chicken sperm during cryopreservation /frozen storage. The study aimed to assess how adding sorbitol and butylated hydroxytoluene (BHT) to the diluent affects the structure and surface ultrastructure of cryopreserved Gaga chicken sperm. A completely randomized design was employed with four treatments and 10 replications including egg yolk-lactate ringer diluent (EYLR) as the control group, EYLR diluent with 3 mM BHT, EYLR diluent with 2% sorbitol, and EYLR diluent with both 3 mM BHT and 2% sorbitol. Semen was collected using a massage technique from 4 male chickens aged approximately 10 months, pooled semen was diluted, packaged in 0.25 mL straws, equilibrated for 2 hours at 5 °C, pre-freeze for 10 minutes, frozen for 24 hours, and thawed for 30 seconds at 37 °C. The parameters evaluated were sperm plasma membrane integrity, acrosome integrity, DNA damage, mitochondrial functionality, and surface ultrastructure. The results showed that the treatment had a significant effect on plasma membrane integrity and post-thawing mitochondrial functionality compared to the control, but no effect was observed on acrosome integrity or DNA damage. The results showed that the combination treatment of BHT with sorbitol had a significant effect on plasma membrane integrity and post-thawing mitochondrial function, but did not affect acrosome integrity or DNA damage when compared to the control group. Ultrastructural observations indicated that cryopreservation caused damage to the head, middle, and tail of the sperm in the control groups. However, these changes were prevented by the diluent containing a combination of BHT and sorbitol. The addition of both components (BHT 3 mM + sorbitol 2%) effectively maintained plasma membrane integrity, mitochondrial functionality, and surface ultrastructure of Gaga chicken sperm during cryopreservation.

Stray cats survive by getting food or drink that is available in the environment, correspondingly, stray cats have relatively high exposure to antibiotic resistance obtained from resistant bacteria found in the environment. The present study was conducted to determine patterns of multidrug resistance and Escherichia coli resistance in stray cats. A total of 50 stray cat anal swab samples were taken randomly from the previously recorded stray cat population in the Surabaya area, East Java, Indonesia. Samples were brought using buffered peptone water. They were cultured on MacConkay Agar differential selective media, and all suspicious colonies of Escherichia coli were examined by biochemical tests. Isolates were then identified, and susceptibility testing was performed according to the Clinical and Laboratory Standards Institute. The results of the resistance test indicated that the multidrug resistance in Escherichia coli bacteria taken from cats was 14.6% (7/48). The high antibiotic resistance of Escherichia coli bacteria in stray cats, which were resistant to many drugs, provides an early warning of environmental health. Environmental health is closely related to animal and human health, especially antibiotic resistance.

Authors: Paramanand Dini Agusti , Rukyat Husnur , Kristianingrum Yuli Purwandari , Widyarini Sitarina
Published: October 2024

The wound healing process goes through a series of complex stages that are mutually continuous, namely inflammation, proliferation, and maturation. Following wound formation and the release of proinflammatory cytokines and growth factors, inflammation occurs immediately after the hemostasis phase. Proliferation occurs when products processed by the growth factors are present. The final stage, maturation, is portrayed by the plan of the extracellular network. This study utilized oil from avocado fruit (Persea americana), which contains linoleic and oleic acid content that supports skin tissue repair. The study aimed to explore the effects of using avocado oil cream on the area of wound healing, the number of inflammatory cells, and the collagen density. Twenty-four female mice, aged eight weeks, were used as experimental animals by making excision wounds using a 4 mm biopsy punch on the dorsal skin on the left and right sides. The mice were divided into four groups based on the percentage of avocado oil in the topical cream included Group K (control, topical cream without avocado oil), Group P1 (5% topical avocado oil cream), Group P2 (10% topical avocado oil cream), and Group P3 (15% topical avocado oil cream). Macroscopic examination of the wounds was conducted daily on days 3, 6, and 9 after topical cream treatment using a digital caliper. A total of 48 skin tissue samples were collected from days 3, 6, and 9 after cream application, which were then processed for histopathology evaluations using hematoxylin-eosin staining and Masson’s Trichrome staining. Hematoxylin-eosin staining was used to count the inflammatory cells, and Masson's Trichrome staining was employed to assess collagen density. The results revealed that avocado oil had a great impact on wound closure after 9 days of 15% avocado oil cream treatment, reducing the inflammatory cells after 3-6 days of 10% avocado oil cream therapy, and increasing collagen density after 9 days of 15% avocado oil cream application, as compared to the control, non-avocado oil cream group. Avocado oil can help close wounds, reduced the number of inflammatory cells, and increased collagen density when used in topical pharmaceutical formulations. Avocado oil cream may, therefore, be considered a viable option for wound repair treatment.

Published: October 2024

This research aims to determine the comparison of the Capital Asset Pricing Model (CAPM) and Arbitrage Pricing Theory (APT) in predicting stock returns of LQ45 index companies on the Indonesian Stock Exchange. Data analysis methods use Simple Regression Analysis, Multiple Regression Methods, and Difference tests. The results of data analysis show that there are differences between CAPM and APT in predicting stock returns. The emergence of varying differences in research results regarding the accuracy of the CAPM and APT models is caused by data disturbances that appear in the historical data used. The CAPM and APT models have a very important element, namely beta (????) as a measure of return on factors that are considered to influence, so this beta (????) must be BLUE (Best Linear Unbiased Estimator) so that the prediction results from the two CAPM and APT models become more accurate and reliable

Environmental Benefits of Transition to Electric School Buses
Authors: Saini Hiren
Published: October 2024

The research paper titled Environmental Benefits of Transition to Electric School Buses examines the substantial environmental and public health advantages of replacing diesel-powered school buses with electric school buses (ESBs) in the United States. With over 500,000 school buses transporting around 27 million students daily, more than 90% of them rely on diesel engines, which emit harmful pollutants such as nitrogen oxides (NOx), particulate matter (PM), and carbon dioxide (CO2). These pollutants contribute to air pollution, climate change, and serious health issues, particularly for children who are more vulnerable to the harmful effects of diesel exhaust. This paper explores the environmental impacts of diesel school buses, including their contribution to greenhouse gas emissions, and highlights the disproportionate effects on disadvantaged communities, which are often located near highways or bus depots where pollution is concentrated. Diesel emissions contribute to climate change through the release of CO2 and black carbon, a potent climate-forcing agent. The paper also emphasizes the health risks associated with diesel exhaust, such as respiratory diseases and increased asthma rates, particularly among children. The transition to ESBs offers a promising solution to these issues. ESBs produce zero tailpipe emissions, reducing NOx, PM, and CO2, which directly improves air quality and lowers greenhouse gas emissions. Additionally, the use of ESBs can significantly reduce the incidence of respiratory problems, improve overall student health, and lead to better academic performance due to fewer absences caused by illness. Beyond environmental and health benefits, ESBs can play a crucial role in advancing climate action by cutting emissions, especially when powered by renewable energy sources. As school districts across the U.S. explore the adoption of electric school buses, the research highlights the transformative potential of ESBs in creating a cleaner, healthier, and more equitable future for children and communities alike.

The research revolved the consequences of performing plastic surgery in terms of harming the human body, but despite its seriousness, the doctor's right justifies it in treating the disease, rather it aims to maintain it, and therefore it is not considered as an attack on it. This is regardless of the outcome of the treatment, as long as the doctor has directed his art to the purpose of treating the patient, and what is based on the permissibility is the recognition of the medical profession by law, and thus inevitably allows all necessary or appropriate actions to be undertaken, and given that these actions aim to preserve the body And it works in his interest so that it proceeds normally and naturally, because the law authorizes it, and it must allow the work of the doctor to be the purpose of medical or surgical intervention "Treat the patient." Treatment is the purpose upon which the right of physicians to medicine and surgery is based. The medical intervention must aim at ridding the patient of his illness, mitigating its severity, preventing the disease, and discovering the causes of the disease.

Study the variation of the pitching frequency of sounding rockets
Authors: Nguyen Van Thang , Nguyen Anh Tuan , Vu Quoc Tru
Published: October 2024

Sounding rockets typically feature an axially symmetric design and are launched vertically to facilitate research and high-altitude atmospheric data collection. Manufacturing errors can cause axial asymmetry, leading to undesirable rocket trajectory dispersion. Sounding rockets are often designed to spin around their axis to mitigate these effects. However, axial spinning motion can resonate with short-period oscillations, creating large normal loads that may damage the rocket’s structures. This paper focuses on analyzing the variations in the pitching frequency, which may help predict the roll resonance phenomenon. In this study, the authors constructed a six-degree-of-freedom dynamic model for a sounding rocket, considering all aerodynamic problems and the variation of inertial characteristics. To determine the pitching frequency, an impulse is applied to the rocket to generate short-period oscillation. The Fourier transform is then used to analyze and obtain the frequency of the rocket while oscillating in space. The results demonstrate agreement with the theoretical model, thereby substantiating the validity of the current method. The findings of this research provide valuable recommendations for the design and manufacturing process of sounding rockets, which may help mitigate the adverse effects of motion resonance during flight.

Published: October 2024

Underwater wireless optical communications are a developing alternative to meet the increasing need for high-speed connections in oceans and seas. Optical wireless communications (OWCs) are more secure and less susceptible to eavesdropping compared to acoustic communications or radio frequency (RF) communications due to their narrow optical beam coverage and reliance on line-of-sight components. Nevertheless, the existence of a hostile eavesdropper can compromise the level of confidentiality achieved by OWC networks. This article provides a concise overview of the latest research conducted on physical layer security (PLS) in underwater optical wireless communication (UOWC). Furthermore, this work presents the relevant unresolved matters, approaches for enhancing secrecy performance, and potential areas for further research.

Power combiners are commonly used in power amplifiers to achieve high power, especially in long-range and medium-range wireless communication device transmission systems. This paper proposes designing and implementing a high-power two-way power combiner operating in the HF (High Frequency) band, aiming to achieve an output power of over 1 kW. The power combiner is designed, implemented, and tested in the laboratory with the following achieved parameters: insertion loss between output and input better than 3.4 dB and isolation between inputs better than 26 dB. The experimental results showed that the proposed power combiner had better performance than existing combiners on the market. Mainly, power combining efficiency is over 88%, the standing wave ratio at ports is less than 1.25, and the operating temperature of the power combiner is less than 50 °C, meeting the set requirements.

Published: October 2024

In this article, we present the research results on the designing and manufacturing method of a high-power harmonic filter applied in the X-band transmitter system. The harmonic filter utilizes Waffle-iron filters and quarter-wavelength converters on the waveguide. As a result, the loss and ripple within the passband are improved, while meeting the requirements of cutting off high-order harmonics. Based on the application of microwave theory and simulation software tools, the research team have calculated, designed and manufactured a harmonic filter that meets all the requested specifications for application in X-band transmitter systems: Loss ≤ 0,12dB@8,9-9,6GHz; Reflection coefficient ≤ -20dB@8,9-9,6GHz; Frequency selectivity ≤ -40dB@2nd harmonic, 3rd harmonic, 4th harmonic.

Published: October 2024

Bài báo này trình bày kết quả tổng hợp các bộ điều khiển trên cơ sở bất đẳng thức ma trận tuyến tính cho hệ thống nâng vật trong từ trường có mô hình toán học phi tuyến mạnh: điều khiển tích phân-phản hồi trạng thái và điều khiển trượt. Các kết quả mô phỏng so sánh và đánh giá các bộ điều khiển trên phần mềm MATLAB/Simulink đã cho thấy các bộ điều khiển hoạt động tốt và bền vững với sự thay đổi của khối lượng vật, vị trí của vật bám sát theo tín hiệu đặt. Tuy nhiên, trong các trường hợp các tham số của hệ thống thay đổi mạnh, hệ thống điều khiển với bộ điều khiển tích phân-phản hồi trạng thái có thể hoạt động không chính xác, thậm chí mất ổn định, còn bộ điều khiển trượt vẫn đảm bảo tính ổn định và bền vững với sự thay đổi của tham số hệ thống.

Mạng cảm biến không dây (Wireless Sensor Network, WSN) bao gồm các cảm biến kết nối không dây để thu thập thông tin từ môi trường và truyền dữ liệu đến trung tâm xử lý. WSN được ứng dụng trong y tế, công nghiệp và tự động hóa nhờ khả năng cung cấp thông tin thời gian thực với chi phí thấp. Nghiên cứu này đề xuất mô hình mạng cảm biến không dây đa kết nối động (Dynamic Multi-Connection Wireless Sensor Network, DMC WSN) kết hợp với kỹ thuật đa truy cập phân chia theo thời gian (Time Division Multiple Access, TDMA) nhằm phân bổ hợp lý thời gian truyền dữ liệu, tránh xung đột tín hiệu và nâng cao hiệu quả truyền tin trong xưởng sản xuất. Kết quả mô phỏng cho thấy, khi không sử dụng TDMA và không điều khiển công suất, dung lượng của cảm biến yếu nhất và dung lượng trung bình đều thấp nhất. Khi áp dụng thuật toán Max-Min để điều khiển công suất, dung lượng được cải thiện. Ngược lại, khi sử dụng TDMA, dù không điều khiển công suất, dung lượng của cảm biến yếu nhất và dung lượng trung bình đều đạt mức cao nhất, cho thấy TDMA giúp tăng hiệu quả truyền tin và đảm bảo dung lượng ổn định cho mô hình DMC WSN trong xưởng sản xuất.

Tax revenue in the province is still low, even though the central government has handed over the tax base to the regions for more than 20 years. The concept of GCG can improve performance and tax revenue in the regions. This study examines the relationship of each pillar of Good Corporate Governance (GCG) to tax compliance and determines the types of GCG pillars that can be prioritized for implementation in a local government agency. This study uses the regional financial management transparency index (ITPAD) as an indicator of the transparency pillar, the fiscal independence index (IKF) as an indicator of the independence pillar, and financial statement audit opinion for the accountability and responsibility pillars. Finally, the Gini ratio is an indicator of fairness. The research sample was taken from all 34 provinces in Indonesia. Secondary data is sourced from publications, books, web pages, and previous research from 2016 to 2020. This period was chosen to exclude data from the COVID-19 pandemic era in Indonesia. The analysis method is panel data multiple linear regression with a random effect model. The results showed that fiscal independence and transparency of a region's budget management positively influence public tax compliance in a provincial area in Indonesia, while the opinion of financial statements and the Gini ratio have no influence. This study implies that to improve public tax compliance in a provincial area in Indonesia, and local governments can prioritize the implementation of the transparency and independence pillars achieved by increasing the ITPAD and IKF scores in their regions. The Ministry of Home Affairs can also encourage regions to enhance transparency and independence by improving ITPAD and IKF so that tax revenue in the regions can increase.
