The high mercury contamination in the ex-gold mining soil is the impetus for the development of soil remediation with amelioration technology that utilizes sub-bituminous coal activated with 10% NaOH (SC-NaOH) to modify the soil surface charge by affecting the chemical properties of the ex-gold mining soil. This research aimed to determine and study the modified surface charge of ex-gold mining soil ameliorated with SC - NaOH. The experimental design used in this study was a Completely Randomized Design with three replications. The treatment was implemented in a pot with equivalent dose: A = 0 (0.0g); B = 10 (0.5g); C = 20 (1.0g); D = 30 (1.5g), and (E) 40 t ha-1 (2g 100g-1 soil). The results showed amelioration technology with SC - NaOH, at the application of 40 t ha-1 on ex-gold mining soils, can modification of soil surface charge through changes in chemical characteristics by increasing the pH H2O EC, CEC, and SOM, respectively of 5.77; 4.33 dS m-1; 2.41 cmol(+) kg-1 and 17.15% compared to the control. Soil surface charge supported by soil minerals [Quartz (SiO2), Graphite (C), and Periclase (MgO)] and also happening decreases transmittance in the OH group (0.18%), which causes an increased adsorption capacity of the soil to Hg, which causes a decrease in total Hg of 2.84 mg kg-1 compared to the control. The correlation between total Hg and soil chemical properties in ex-gold mining soil ameliorated with SC â€“ NaOH (Total Hg with SOM > Î”pH > EC > pH H2O > CEC).

Gamma irradiation techniques have been used in various fields, such as sterilizing medical equipment and food products. In such a process, monitoring the dose of radiation using radio radiochromic dosimeter is important to guarantee the accuracy of the radiation dose absorbed by the irradiated materials. Radio chromic dosimeters usually consisted of radiation-sensitive dyes that could change colors when exposed to radiation. In this research, natural dyes in the form of anthocyanins obtained from roselle flower extract (Hibiscus sabdariffa L.) have been used as radio chromic indicators. The radio chromic indicators have been made in liquid using water solvent and gel using a tragacanth gelling agent. Each radiochromic indicator's pH values varied between 2 and 11 using NaOH and HNO3 solutions. All radio chromic indicators were then gamma irradiated using a Co-60 radiation source and tested for stability at 8Â°C under closed storage conditions. The characterization was performed using UV Vis spectrophotometry. The results showed that roselle flower extract was sensitive to gamma radiation as indicated by decolorization, and their sensitivity increased when made in the form of gel at pH 2 and 5. The stability test also showed that the anthocyanin content was stable after being maintained for 28 days in a closed storage at 8Â°C. With such differences in sensitivity of the roselle flower extract when used in either liquid or gel solution, the radio chromic indicators should find wide application in the future, depending on the radiation doses given to the solutions.

Cocoa beans are a common food ingredient recognized by the public because they can be made into various products and have health benefits such as antioxidant, anti-inflammatory, and anti-diabetic if appropriately processed. This study used the Forastero variety cultivated at Sukabumi region, Indonesia, as a cocoa bean sample. This study aimed to analyze phytochemical properties and the bioactive compounds content of cocoa beans using GC-MS affected by various drying methods. The methods used were sun drying, cabinet drying, and freeze drying. The observed parameters to determine the cacao bean quality were antioxidant capacity, phenol and flavonoid content, and bioactive compound. The result showed that the drying method affected dried cocoa beans' phenol and flavonoid content and antioxidant activity. However, the freeze-drying gave the best phytochemicals properties in phenol content (5,6785 mg GAE/g), flavonoid (64,33 mg QE/g), and antioxidant capacity (42,17% inhibition on DPPH 0,1mM). The result was in line with volatile compounds with proven high biological activity. Cabinet drying produced cocoa beans, which is better than sun drying. The freeze-drying maintains lactones, ketones, alcohols, aldehydes, and phenols. The freeze-dried cocoa beans had the highest content of Î³-Tocopherol, 2,4-Di-tert-butylphenol, 5-hydroxymethylfurfural, neophytadiene, and palmitic acid as antioxidants. The freeze-drying method could be considered for producing dried cocoa beans as a supplement ingredient.

Published: October 2023

This paper introduces an emotion-based BDI (Belief, desire, intention) methodology to model decision-making during fire evacuation simulations while considering human emotions. The methodology is designed to represent human decision-making processes in graphical representations, which can be simply translated for the implementation phase to simulate various case studies. The methodology utilizes the Belief, Desire, and Intention architecture and the OCEAN Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism) personality behavior to represent decision-making processes graphically, making it easy to translate into a simulation. The methodology aims to create a more realistic simulation closer to real human behavior by incorporating emotions that affect decision-making. In this paper, we validate the emotion-based BDI methodology by replicating the bushfire Australia case study and benchmarking with the previous work on BDI fire evacuation. From the comparison, we found that both results share almost similar patterns. The results show "dead while still unaware" (0% vs. 0%), "dead while deciding what to do" (69% vs. 48%), "dead while defending" (6% vs. 8%), and "dead while preparing to defend" (6% vs 28%), "dead while preparing to escape" (4% vs 0%) and "dead while escaping" (15% vs 20%). The results show that in our Simulation, there is a death related to preparing to escape (4% vs 0%). However, the other causes of death have an almost similar percentage of death causes. Hence, based on the comparison, supporting and validating our emotion-oriented simulation model is considered adequate. Therefore, this emotion-based BDI methodology can systematically reproduce human cognition and emotion.

Published: October 2023

College plays a vital role in defining a student's future by providing relevant education, skills, and exposure. The choice of college courses heavily influences their career foundation and employment skill sets. However, the expanding number of college courses often leaves students struggling to make the best choice, leading to dropouts due to the lack of interest. Many systems rely on existing student reviews or the popularity of the course itself, which may not always result in relevant recommendations. Hence, some systems use sentiment analysis (SA) to evaluate students' opinions, considering qualitative and sentiment data to understand their interests better. However, current SA performance struggles to extract meaningful words due to dataset availability. Hence, a course recommendation system based on students' interests and competence would be valuable. This paper focuses on evaluating and understanding existing systems to provide students with an effective course recommendation system. It includes first gathering useful data that would improve the use of SA. Next, feature extraction techniques Term Frequency-Inverse Document Frequency (TF-IDF) and N-gram were implemented and compared. SA will be performed to increase the relevance of the student's interests to recommend a course by implementing Fuzzy Logic and K-nearest neighbors. These algorithms will be evaluated by performance metrics such as accuracy to determine the most efficient way to recommend a course. The findings highlight the importance of considering students' subjective preferences and interests for better outcomes regarding student success and graduation rates.

Published: October 2023

This research investigates fiber Bragg grating (FBG) temperature sensing performance in monitoring nonâ€”uniformity of non-thermal plasma (NTP) formation in a packed-bed reactor using FBG operating at atmospheric pressure. Two FBGs made from germanium doped fiber were embedded inside and outside the PBNTP reactor to allow for comparison between the temperatures inside and outside of the reactor to be made. Each FBG comes with three grating series, which allow the reactor temperatures at three different locations inside or outside the reactor to be measured and compared. Two types of plasma, namely nitrogen (N2) and argon (Ar) were generated in the reactor at a gas flow rate in the range of 2 - 7 L/min and applied voltage in the range of l - 20 kV. It was found that the PBNTP reactor temperature varies up to 20 oC at different positions inside and up to 40 oC outside of the reactor. This finding shows the non-uniformity of plasma formation and the nature of the plasma's localized thermodynamic equilibrium (LTE). The sensitivity of the FBG temperature sensor used in this study is estimated at 10.36 - 10.50 pm/oC.

This study investigated the effects of carbon-aramid arrangement and strain rate on crush tube energy absorption. Round composite tubes, each consisting of three layers of fabric, were made using four different carbon-aramid hybridization schemes. Hand lay-up and compression bladder molding were used in the fabrication process. In two hybridization schemes, carbon-aramid fabrics were arranged to evaluate the effect of axially graded impedance relative to the tube impact end. Static crush and low-velocity impact (LVI) tests were conducted, and the force-displacement responses, energy absorption characteristics, and failure modes were compared. Test results revealed that energy absorption was 20% to 60% higher in the low-velocity impact test than in static crush, regardless of the hybridization schemes. In both tests, material arrangement played a surprisingly important role that was comparable to the tube carbon content in energy absorption. Maximum specific energy absorption of 26.21 kJ/kg was obtained in the hybridization scheme with the low impedance at the initiator end, with increasing impedance towards the impact end. This amount of specific energy absorption is almost equivalent to the other hybridization scheme that has twice the carbon fiber content. This scheme facilitated initial damage modes that favored progressive folding in the rest of the tube. This study presents the idea of enhancing the crashworthiness of crash boxes using axially graded impedance material arrangement. It is recommended that the idea be subjected to more testing for verification and potential commercialization.

Authors: Kian Ang Yong , Lim Siow Chun
Published: October 2023

The manufacturing sector constitutes a cornerstone of Malaysia's economic landscape, significantly contributing to the nation's Gross Domestic Product (GDP). This pivotal role, however, is accompanied by substantial energy requirements, placing the manufacturing sector among the highest energy consumers across various industries in the country. This study primarily focuses on assessing the solar energy potential within the manufacturing sector. The objectives encompass two key facets: firstly, simulating the attainable energy yield from a photovoltaic (PV) system integrated into manufacturing industry facilities, and secondly, evaluating whether the PV system's generated electricity aligns with the energy requirements of selected manufacturing sectors, namely chemical and metal manufacturing plants. Sixteen companies have been selected from the chemical and metallurgical sectors for this study. The design process for the solar photovoltaic systems within these facilities necessitates determining the factory's location and rooftop area. Additionally, assessing the total savings is imperative to gauge the viability of the solar energy generated by these manufacturing plants. Among the 16 companies analyzed, intriguingly, 5 companies have demonstrated the capacity to fully transition to solar energy to cater to their energy needs. Notably, one of these companies can harness solar power to meet an impressive 179.91% of their energy demand by optimizing available space for solar power generation. This transition could potentially translate into substantial savings exceeding RM1 million in electricity costs.

Published: October 2023

The ongoing climate change resulting from the effects of global warming is manifested through increased variability and a rise in extreme precipitation events. Given this situation, it becomes imperative for farmers to adapt to these changes to ensure the long-term sustainability of their businesses. Therefore, this research aimed to assess extreme precipitation for planning adaptation strategies for agricultural water resources in the Selo watershed, Tanah Datar Regency, West Sumatra Province, Indonesia. Climate Hazards Group Infrared Precipitation and Stations (CHIRPS) data were used to accomplish this, spanning 1981 to 2020. A set of indices recommended by ETCCDI, including PRCPTOT, CDD, CWD, R95p, R99p, SDII, R10mm, R20mm, R30mm, and R40mm were employed to assess extreme precipitation. Climate Data Operator (CDO) and GrADS were conducted for downscale and plotting data.

Furthermore, the Mann-Kendall test was conducted to determine the significance of change trends in the indices. R-Climdex was used to determine the extreme event based on the data used. The results showed that all indices indicated wet conditions during the period 1981-2020. The topographic characteristics of the watershed served as a basis for selecting suitable adaptation strategies within the agricultural water resources sector. One potential approach involves integrating conservation-based adaptation practices with comprehensive watershed management techniques. Factors such as the areaâ€™s sensitivity to changes in the total intensity or frequency of precipitation, combined with the local environmental conditions, can be considered in determining the optimal adaptation approach.

Climate change causes an increase in the frequency and intensity of drought and plant-disturbing organisms, causing low agricultural production. This issue then affects the socio-economic conditions of the farmerâ€™s household due to low income and consumption. This study aimed to determine the proportion of food expenditure, analyze the energy consumption level, and the food security level of farmer households. The location was determined by purposive sampling, a proportional technique with a sample of 344 farmer households. The data analysis method used income and expenditure analysis, food expenditure share, food consumption, and food security analysis. The results showed that the proportion of food expenditure for farmer households was 58.75%, that were categorized as food security. The energy consumption level of 1833.37 kcal / person/day is classified as moderate. The level of food security showed that 39.83% were classified as food secure, 29.65% as food vulnerable, 14.83% as lack of food, and 15.70% as food insecure. Based on these results, to improve food security at the level of food insecurity and lack of food, efforts are made to increase the cropping index by drilling wells or ponds, government support for agricultural production facilities, and strict regulations regarding the conversion of agricultural land. In food vulnerable, farmer households must apply through the promotion of activities that generate non-agricultural income. To maintain food security, made to diversify food to meet ideal nutrition.
Ucrania y el dilema de la seguridad

Published: October 2023

Las acciones de los líderes de las principales potencias mundiales se nutren esencialmente de las ideas de dos tradiciones teóricas de la política internacional; una supone que a través de la cooperación se podrá alcanzar una paz duradera y la otra sostiene que frente a la propia naturaleza de los conflictos solo se puede perseguir la estabilidad. La historia de las relaciones internacionales ofrece evidencia para ambas perspectivas. Ahora mismo, el conflicto abierto por la invasión de la Federación Rusa a Ucrania ha instalado nuevamente el dilema de la seguridad entre las principales potencias. En el orden internacional emergente solo se puede buscar la estabilidad a través de un nuevo equilibrio de poder.
"Cabalgar a hombros de una divinidad destructora"
Authors: Klein Alejandro
Published: October 2023

El siguiente trabajo plantea como objetivo una indagación preliminar de las ideas de Giddens en torno a lo social, expresado en términos de modernidad, confianza básica, sistemas expertos y políticas de riesgo, recorriendo metodológicamente sus principales textos, contrastados a su vez con otros (desde otras disciplinas) que permiten una nueva aproximación a los mismos. Giddens señala el lugar de la reflexividad y los sistemas expertos como estructuras que integran el mundo, lo social, las experiencias cotidianas y la constitución del yo y en esa versión de lo social que se denomina modernidad. Todos estos factores se aúnan en el riesgo y la oportunidad, pero enmarcados en el logro de un sentimiento de identidad a la que se siente como propia y auténtica. A partir de estas cuestiones, el presente artículo tiene por objetivo intentar profundizar sobre qué se entiende por lo social y especialmente, que grado de confiabilidad puede merecer el mismo, desde la perspectiva de Giddens, pero integrando a su vez otras perspectivas culturas, sociales y psicoanalíticas, para intentar situar las implicaciones epistemológicas en juego, señalando sus alcances y limitaciones. Como resultados se indica que es posible percibir una cierta concepción de la trama social en términos de integración y previsibilidad, pero siempre de acuerdo a un contexto social específico. De esta manera, las ideas sociales de Giddens son criticables, pero no dejan de ser atendibles en tanto su análisis sociológico no elude perplejidades, confusiones y dificultades, que indican un social que escapa a dimensiones racionales, funcionalistas y hasta estructuralistas.
Los espacios de lo urbano. La ciudad proyectada y la ciudad vivida
Authors: Carisimo Adriana
Published: October 2023

Este ensayo presenta diálogos sobre lo urbano a partir de algunas ideas de autores fundamentales en la reflexión sobre la ciudad en los siglos XX y XXI, en primer lugar, presenta el diálogo entre las propuestas de Jane Jacobs y Jan Gehl sobre las escalas en las que son vividas y planificadas las ciudades, ambos autores revelan la importancia de pensar en la gente (las personas, la ciudadanía) y en la escala humana al momento de diseñar los espacios urbanos. En segundo lugar se presenta un diálogo sobre el derecho a la ciudad, con algunos aportes de Henry Lefebvre y David Harvey, el enriquecedor camino que ha recorrido esta noción acuñada durante la década de 1960 la ha llevado a convertirse en epítome de un movimiento social apropiado por los actores. Sin ahondar en las matrices teóricas que han conformado estas propuestas, la meta de este texto es abrir el debate y presentar algunos interrogantes sobre el sentido de la experiencia urbana en lo que respecta a las diferencias entre los espacios proyectados y los espacios vividos, así como también reflexionar en términos exploratorios sobre la importancia de la participación de la ciudadanía en la elaboración de las políticas públicas.
Barreras que enfrentan las Universidades para la transferencia de la investigación a las políticas públicas
Authors: Palacios Evelyn
Published: October 2023

En la historia, la universidad y las políticas públicas han tenido interacción desde tiempos remotos. No es difícil evidenciar que aún antes de ser conocidas como tales, las instituciones de educación universitaria reunían a personas de alta influencia social, quienes muchas veces tenían en sus manos la posibilidad de mejorar la calidad de vida de las personas, La universidad y la sociedad han tenido conexión desde siempre, y su influencia recíproca con el entorno es innegable. Sin embargo, se levantan impedimentos para el aporte formalizado de la educación superior como espacio de generación de conocimiento científico hacia la sociedad. El presente trabajo presenta una reflexión acerca de las barreras más frecuentes que enfrentan las universidades para la transferencia de la investigación que generan hacia las políticas públicas. Entre aquellas barreras mas frecuentes se detallan y describen: el financiamiento de la investigación, la politización de las universidades, las instancias de comunicación con los tomadores de decisiones, la vinculación de la universidad con el medio, la temporalidad de la investigación, las competencias de los nuevos lideres investigadores, la burocratización universitaria, la contribución social como elemento misional y estratégico en la universidad, pocos espacios de trabajo interdisciplinarios. Cada una de estas barreras implican nuevos desafíos para la organización. Se propone, para superarlos, fomentar un trabajo mancomunado entre los diversos actores en pos de que las universidades puedan empoderarse con su misión de servicio y así verse involucradas en iniciativas colaborativas con el sector público y la sociedad civil.

Sandflies (Diptera; Psychodidae) are medical and veterinary vectors that transmit diverse parasitic, viral, and bacterial pathogens. Their identification has always been challenging, particularly at the specific and sub-specific levels, because it relies on examining minute and mostly internal structures. Here, to circumvent such limitations, we have evaluated the accuracy and reliability of Wing Interferential Patterns (WIPs) generated on the surface of sandfly wings in conjunction with deep learning (DL) procedures to assign specimens at various taxonomic levels. Our dataset proves that the method can accurately identify sandflies over other dipteran insects at the family, genus, subgenus, and species level with an accuracy higher than 77.0%, regardless of the taxonomic level challenged. This approach does not require inspection of internal organs to address identification, does not rely on identification keys, and can be implemented under field or near-field conditions, showing promise for sandfly pro-active and passive entomological surveys in an era of scarcity in medical entomologists.

Background: Core Stability Exercise (CSE) is a globally acknowledged intervention for managing chronic low back pain. However, the sustained adherence of patients with chronic low back pain to CSE can be challenging, mainly due to the absence of supervision and guidance from physical therapists during home-based exercise sessions. Consequently, exercise compliance tends to decline, resulting in suboptimal long-term effectiveness of the intervention. In this trial, our primary aim is to evaluate the potential therapeutic equivalence between home-based rehabilitation training employing key point identification technology and exercise guidance administered in a hospital setting.
Methods: In this trial, we will randomly assign 104 adults with chronic low back pain (CLBP) to either an intervention or control group, with 52 participants in each group. Both interventions will consist of three weekly 0.5-hour sessions of Core stability exercise (CSE). The intervention group will engage in home rehabilitation training utilizing key identification technology for movement, while the control group will perform supervised exercises in a hospital setting. Outcome assessments will be conducted at 4 weeks and 16 weeks after randomization. The primary outcome measure will be the change in pain intensity (based on Numeric Rating Scale - NRS scores) from baseline to 4 weeks. Secondary outcomes will include changes in physical function (measured by the Oswestry Disability Index, ODI) and lumbar spine mobility, as well as activity participation and treatment satisfaction.
Discussion:If home-based rehabilitation method is demonstrated to be non-inferior or even superior to traditional face-to-face exercise guidance, it could significantly advance the adoption of digital medical care and contribute to improving the overall health of the population.

Background
The COVID-19 pandemic reinforced the role of health and social care research in policy and practice decision-making. Global research priorities were rapidly identified. However, the diverse health, social and economic impacts in different countries and communities, intersecting with local pre-existing inequalities, warranted a rapid, localised approach so that evidence was maximally useful to policy and practice decision makers. The aim of this paper is to describe how the Wales COVID-19 Evidence Centre engaged multiple stakeholders in a rapid COVID-19 evidence needs prioritisation process, to present the results of this exercise and evolving evidence needs at three time points during the pandemic, and to describe key learning from working with multiple stakeholders.
Methods
Stakeholder groups across policy, practice, and public domains were invited to submit up to ten COVID-19-related health and social care evidence needs via our Stakeholder evidence needs Prioritisation Exercise (ScoPE) across three prioritisation rounds (Spring/Summer 2021, Autumn/Winter 2021, and Spring/Summer 2022). Urgent, high-priority needs were also submitted via our fast-tracked process. Returned evidence needs were assessed against agreed prioritisation criteria.
Results
44 stakeholder groups proposed 223 questions (212 ScoPE and 11 fast-tracked routes); a total of 78 questions were accepted onto our work programme and answered across 58 different studies (50 evidence syntheses, eight primary research). Evidence needs answered by our work programme mapped closely to the broader and evolving COVID-19 context.
Conclusion
We successfully engaged multiple stakeholders (including the public) in one process, demonstrated the feasibility of virtual methods, were able to track a rapidly evolving and complex public health situation, and identified evidence needs that directly informed policy and practice guidance. Further investment and resource in the Science-Policy-Practice Interface during early phases of prioritisation exercises could help to enhance research question specificity and impact planning, thus expediting evidence prioritisation, delivery, and impact.

The study aimed to investigate Effectiveness of Artificial Insemination after Estrus Synchronization in Dairy Cattle Breeding in Mirab and Misrak Badawacho districts. Ninety respondents were randomly selected and interviewed from two districts and six kebeles. Also, 90 cows were selected for evaluation of prostaglandin-based estrus synchronization's effectiveness. Descriptive statistics, and chi-square tests used to analyze the data. The average age at first service for female native and crossbred cows were 41.9 ± 5.3 and 30.9 ± 3.1 months, average daily milk yield (1.7 ± 0.5 and 6.31 ± 1.2 liters), average lactation length (8 ± 1.0 and 9.71 ± 1.0 months), average age at first calving (50.85 ± 3.95 and 39.35 ± 8.1 months), average calving interval (23.4 ± 4.2 and 21.4 ± 2.85 months), average days open (208.2 ± 36.2 and 148.4 ± 36.8) for local and crossbred, respectively. Natural pasture and crop residue were dominant feed sources, and cattle were typically housed with household members. The purpose of rearing cattle in the contemplate area is milk followed by the source of income, meat, traction, and manures. Most of the respondents (85.6%) used the pond as a source of water for their cattle in both districts. The respondents showed a preference for female cattle with high milk yield, reproduction ability, good temperament, and coat color and natural coupling was the greenest method acting of reproduction. Major procreative problems in dairy were failure to cycle and poor conception rate in the study areas. The potency of artificial insemination after estrus synchronization has an overall conception rate (57.8%) after 60 + days of pregnancy diagnoses. Conception rate has not shown a significant difference at P < 0.05 between the district, age, and Body condition Score, but there is no a significant difference between breed, parity, and time of insemination. This low pregnancy rate is due to several factors related to management, heat detection problem, seminal fluid quality, and artificial insemination time. The study suggested using appropriate animal selection for artificial insemination, trained AI (Artificial Insemination) technicians, and farmer awareness to improve the effectiveness of synchronization and efficiency of artificial insemination.

Published: October 2023

Objective: Antineutrophil cytoplasmic antibody (ANCA)–associated vasculitis (AAV) is a group of illnesses that cause inflammation and alterations to small vessels in the body. Some of the most common and detrimental manifestations, including alveolar hemorrhage and glomerulonephritis, are caused by this capillary inflammation. We sought to clarify whether patients with AAV would have abnormal nailfold capillaries when evaluated with nailfold videocapillaroscopy.
Methods: Patients with a current diagnosis of AAV and a control group were identified for enrollment. Nailfold videocapillaroscopy images were used for a semiquantitative analysis on capillary density, morphology, dilation, and microhemorrhage after review by 2 rheumatologists. Disease characteristics, occurrence of recent disease flare, and presence of ANCA were recorded.
Results: Thirty-three patients with a diagnosis of AAV and 21 controls were recruited. The AAV group had a median age of 59 and 17 (52%) were women. Granulomatosis with polyangiitis was the most common diagnosis (19 [58%]), followed by eosinophilic granulomatosis with polyangiitis (7 [21%]) and microscopic polyangiitis (7 [21%]). Twenty-seven patients (82%) had positive ANCA tests. After assessment of capillary density, dilation, morphology, microhemorrhages, and disorganization, there were no statistically significant differences between the 2 groups.
Conclusion: There was no evidence of differences in nailfold capillaroscopy abnormalities between those diagnosed with AAV and the control group. While this cohort was relatively small, we did not find a high enough prevalence or specific phenotype of capillary abnormalities that could aid in diagnosis or prognostication of these diseases in the clinical setting.

Published: October 2023

Background Children with severe basic diseases and low immunity in the intensive care unit (ICU) are usually in critical condition. It is important to help clinicians choose the appropriate empirical antibiotic therapy for clinical infection control. Methods 281 children with bloodstream infection (BSI) were retrospectively analyzed. Statistical software was used to compare and analyse the basic data, pathogenic information, and drug resistance of the main bacteria.
Results A total of 328 strains were detected, including gram-positive bacteria (223, 68%), mainly including coagulase-negative staphylococci (CoNS), gram-negative bacteria (91, 27.7%), fungi (14, 4.3%). There were 243 cases of single pathogen infection and 38 cases of mixed pathogen infection. Results of binary logistic regression analysis showed that lengths of hospitalization of 0～<30d was an independent risk factor for mixed infection, and length of hospitalization of 15～<60d was an independent risk factor related to death. Compared with Escherichia coli, the proportion of extended-spectrum β-lactamases (ESBLs) was higher producing by Klebsiella pneumoniae, and its resistance to some β-lactamides, quinolones antibiotics were lower. 27 isolates of multi-drug resistant (MDR) bacteria were detected, among which carbapenem-resistant Acinetobacter baumannii (CRAB) accounted for the highest proportion (13, 48.2%). Conclusion CoNS was the principal pathogen of BSI in the intensive care unit (ICU) of children, and Escherichia coli was the most common gram-negative pathogen. It is necessary to continuously monitor patients with positive blood culture, pay special attention to the detected MDR bacteria, and strengthen the application management of antibiotics and the prevention and control of nosocomial infection.
