Authors: Al-ammery Ruqaya Kareem Abass , Chabuck Zainab Adil Ghani
Published: May 2024

Background:

The antimicrobial resistance of Acinetobacter baumannii is of major concern. It is one of the commonly distributed nosocomial pathogens, and its strains are frequently reported to demonstrate resistance to the most routinely prescribed antibiotics in varying degrees.

Objective:

This study aimed to detect the inhibitory effect of chamomile extract against the efflux pump of A. baumannii.

Materials and Methods:

Clinical samples (125) were collected from different sites (urine, sputum, wound, and burn swabs), followed by A. baumannii isolation and identification, and detection of tetracycline susceptibility test by disk-diffusion. Later on bacterial efflux pump activity was detected by ethidium bromide cartwheel assay and water extract of chamomile was used as an inhibitor of efflux pump A. baumannii.

Results:

The percentage of A. baumannii isolation 23/125 (18.4%) that distributed as 25% isolates were obtained from sputum, 17.9% isolates from burns, whereas 16% and 12.5% isolates from urine and wounds respectively. It showed various resistances against different members of the three generations of tetracyclines, with the highest resistance against minocycline 47.8% followed by resistance to tetracycline and doxycycline as 43.5% and 39%, respectively. Efflux pump was detected in all cases, water extract of chamomile showed a significant inhibitory effect especially at 80 mg/mL concentration.

Conclusion:

Efflux pump is an important mechanism for tetracycline resistance among A. baumannii isolates, and the watery extract of chamomile can be considered a prompt inhibitor for this pump.
The effect of carbonyl cyanide m-chlorophenyl-hydrazine on antibiotic susceptibility in MDR Enterobacteriaceae isolates in Babylon, Iraq
Authors: Jebur Hadeel Qasim , Al-Charrakh Alaa H
Published: May 2024

Background:

One of the efflux pump inhibitors is carbonyl cyanide 3-chlorophenylhydrazone (CCCP) that has often been found to increase the susceptibility of a number of multi-drug resistant (MDR) MDR bacteria, isolated from human clinical specimens.

Objectives:

To investigate the role of active efflux system to aminoglycoside and quinolones resistance in clinical isolates of Enterobacteriaceae using the efflux pump inhibitor CCCP.

Materials and Methods:

Enterobacteriaceae isolates were recovered from different clinical samples from hospitalized patients. The minimum inhibitory concentrations (MICs) of antibiotics (levofloxacin, ciprofloxacin, and gentamycin) were compared with and without the efflux pump inhibitor (CCCP) in order to confirm the effective role of the efflux pump in our isolates.

Results:

The results found that out of 280 clinical samples, only 134 (47.1%) isolates belonged to Enterobacteriaceae. Polymerase chain reaction (PCR) results showed that six (42.8%) out of 14 selected MDR isolates were positive for efflux pump gene oqxA. However, no isolates showed positive results for the efflux pump oqxB. The results of MIC for 14 Enterobacteriaceae isolates against these three antibiotics showed that all isolates had MIC ≥128 μg/mL in the absence of CCCP for levofloxacin, ciprofloxacin, and gentamycin. The results showed the MIC of levofloxacin and ciprofloxacin were reduced for isolates, and the growth of bacteria was inhibited in presence of the CCCP. However, all Enterobacteriaceae isolates showed high MIC values (≥128) even in the presence of the CCCP which indicates no effect the inhibitor in reducing the MIC of the isolates for Gentamycin.

Conclusion:

From this study, we can conclude that high prevalence of efflux pumps gene (oxqA) was detected among MDR and XDR Enterobacteriaceae isolates and the efflux pump inhibitor (CCCP) has a positive effect and improves the sensitivity of MDR isolates to ciprofloxacin, levofloxacin but not gentamicin.

Authors: Al-Ghazal Sara A , Al-Hassnawi Huda H
Published: May 2024

Background:

The ability of Staphylococcus aureus to cause disease has been attributed to an impressive spectrum of virulence factors.

Objective:

The study investigated molecular detection of pore-forming leuko toxin (Panton–Valentine leucocidin [PVL]) in S. aureus that is resistant to methicillin (MRSA) isolated from skin infections.

Materials and Methods:

All 100 isolates of S. aureus were obtained from clinical samples (burn, wound, impetigo, boil, acne, abuses, folliculated, infected atopic dermatitis, and secondary infection), and 24 of these had been confirmed as MRSA. Antibiotic susceptibility patterns, mecA, 16sRNA, and PVL genes were isolated and detected by polymerase chain reaction (PCR).

Results:

All isolates were determined to be resistant to cefoxitin discs and oxacillin by using phenotypic analysis, and a genotypic investigation revealed that 79.16% of them carried the mecA gene. Additionally, the data showed that 58.33% of MRSA isolates contain the PVL gene and 83.33%% of MRSA isolates harbor of 16sRNA gene.

Conclusions:

The study detected a high S. aureus isolates percentage in a burn, followed by impetigo, wound, and boil, respectively. A higher percentage of MRSA isolates contain the PVL gene, mecA, and harbor of 16sRNA gene.
A Cytokine That Is Involved in Immune Responses in Chronic Hepatitis B Virus Patients
Authors: Abady Noor R , Al-Al Hindi Zeana Shakir
Published: May 2024

Background:

The present research examines the part interleukin-17 (IL-17) plays in the progression of liver disease in people infected with the long-term hepatitis B virus. A proinflammatory cytokine called IL-17, linked to a number of autoimmune disorders, was examined in serum samples taken from different participant groups.

Objective:

The aim of this study is to examine the levels of IL-17 in various participant groups and understand any possible influence on the development and course of liver fibrosis.

Materials and Methods:

There were four groups in the study: asymptomatic HBsAg carriers (n = 42), chronic hepatitis B (CHB, n = 57), liver cirrhosis (LC, n = 59), and the normal control group (n = 80). an Enzyme-Linked was used to measure the amounts of IL-17, while reverse transcription polymerase chain reaction was used to find IL-17 mRNA in peripheral blood mononuclear cells (PBMC).

Results:

Liver disorders such as cirrhosis and CHB are associated with elevated levels of IL-17. Both the subjects’ serum and PBMCs showed these elevated IL-17 levels, demonstrating a strong correlation with inflammation. These findings highlight the significant function of IL-17 in the possible management or treatment of a variety of liver-related conditions.

Conclusion:

The investigation comes to the conclusion that IL-17 levels increase as liver disease severity increases, suggesting that it is involved in the development of fibrosis and the progression of the disease. Gaining insight into the function of IL-17 may help develop more effective therapies for CHB and LC patients. It is crucial to conduct further research in this area to develop tailored therapeutics.
Exploring mindfulness interventions for stress resilience in newly graduated nurses: A qualitative study
Authors: Wang Shu-Chen , Shih Shih-Ming , Kuo Li-Chuan
Published: May 2024

ABSTRACT

Objectives:

In an aging society coping with workforce challenges, successful hospital management hinges on the recruitment and retention of nurses. It is of utmost priority to address job stress and fortify mental resilience. While quantitative research supports investigating the stress-alleviating effects of mindfulness for nursing staff, obtaining a direct perspective from nurses is essential to comprehend how they navigate burnout and apply mindfulness for stress management. This qualitative study aimed to explore newly graduated nurses’ experiences who participated in a mindfulness course and evaluate the practical application of acquired strategies in their work and daily lives, providing insights for retention strategies in health-care institutions.

Materials and Methods:

Thirty-one recently graduated nurses participated in an 8-session weekly in the mindfulness program. Qualitative data were obtained through focus group discussions during each session and subjected to thematic analysis.

Results:

Five key themes were generated to show how nurses experience mindfulness training: (1) shedding light on workplace stress and adaptation; (2) stress upon entering the workforce; (3) reactions to the vicious cycle of anxiety responses to stress through mindfulness practices; (4) discovery of daily life pleasures and obstacles encountered during the mindfulness course; (5) obstacles encountered during the mindfulness course. Through participation in the program, the subjects’ levels of mindfulness of stress responses were enhanced.

Conclusion:

This study underscores the advantages of mindfulness courses for newly graduated nurses and emphasizes the crucial role of workplace support. Practical recommendations for nursing administrators and educators include fostering familiarity with the health-care environment, promoting teamwork, and addressing anxiety related to handovers. Mindfulness breathing training has proven effective in alleviating pressure during shift transitions. Nursing managers can enhance staff well-being by creating moments of happiness, encouraging positive experience sharing, and organizing outdoor activities. Suggestions for future research involve refining the implementation of the Mindfulness-Based Stress Reduction course for accessibility and effectiveness, extending courses to other health-care professionals to promote team harmony, and positively impacting nursing staff’s well-being and performance.

A European renewable supergrid for Europe’s future weather-dependent power system
Authors: O’Connor Eddie , Fitzgerald John , Kjaer Christian
Published: May 2024

Europe is facing an unprecedented energy challenge. Europe must transition to a renewables-dependent and thus weather-dependent energy system. Renewable generation technologies in solar and onshore and offshore wind have matured to become commercially and technologically feasible. However, the introduction of renewables at the speed necessary presents considerable challenges, most notably on the electricity grid. Grid technology and infrastructure are far from where they need to be to accommodate the needed level of renewables, especially in the offshore space where no grid currently exists. A more holistic approach to grid planning is required. Lessons are drawn from the Midcontinent Independent System Operator (MISO) in the US which delivers significant cost-savings across 15 US states. A European-wide supergrid with a significant offshore grid could provide similar benefits by alleviating the challenges of renewable energy and connecting the best offshore renewables to demand centres across the continent. The planning, development and operation of such a grid would face institutional barriers and would require a complex new European Governing Framework.

Unifying the Three Algebraic Approaches to the CSP via Minimal Taylor Algebras
Authors: Barto Libor , Brady Zarathustra , Bulatov Andrei , Kozik Marcin , Zhuk Dmitriy
Published: May 2024

This paper focuses on the algebraic theory underlying the study of the
complexity and the algorithms for the Constraint Satisfaction Problem (CSP). We
unify, simplify, and extend parts of the three approaches that have been
developed to study the CSP over finite templates -- absorption theory that was
used to characterize CSPs solvable by local consistency methods (JACM'14), and
Bulatov's and Zhuk's theories that were used for two independent proofs of the
CSP Dichotomy Theorem (FOCS'17, JACM'20).
As the first contribution we present an elementary theorem about primitive
positive definability and use it to obtain the starting points of Bulatov's and
Zhuk's proofs as corollaries. As the second contribution we propose and
initiate a systematic study of minimal Taylor algebras. This class of algebras
is broad enough that it suffices to verify the CSP Dichotomy Theorem on this
class only, but still is unusually well behaved. In particular, many concepts
from the three approaches coincide in this class, which is in striking contrast
with the general setting.
We believe that the theory initiated in this paper will eventually result in
a simple and more natural proof of the Dichotomy Theorem that employs a simpler
and more efficient algorithm, and will help in attacking complexity questions
in other CSP-related problems.

Published: May 2024

Around the world, traffic congestion is a major issue that affects everyday commutes, economic activity, and the sustainability of the environment. The goal of this research project is to use machine learning approaches to address the problem of traffic congestion. Through the utilization of an extensive dataset that encompasses several spatiotemporal parameters, including date, time, weather, and holiday indicators, the research creates predictive models that enable precise forecasting of traffic congestion levels. In order to determine how well machine learning predicts congestion dynamics, the research uses multiple regression methods, such as MLP Regressor, Stacking Regressor, and SVR. Historical traffic volume data is used to train and assess the models, making it possible to identify the main variables impacting patterns of congestion. The findings demonstrate how weather, time of day, and holidays all have a major impact on traffic congestion. Transportation authorities and urban planners may enhance overall urban mobility, optimise infrastructure utilisation, and regulate traffic flows proactively by leveraging the predictive capabilities of machine learning models. This work advances intelligent transport systems by offering a strong framework for anticipating and controlling traffic congestion. The results highlight the significance of utilising data-driven methodologies to tackle intricate urban issues, ultimately cultivating more effective and sustainable urban settings.

Published: May 2024

El conocimiento de los indicadores de juego que se manifiestan durante la competición capacita a los entrenadores para diseñar planes de entrenamiento adaptados a las demandas competitivas. El objetivo de este estudio fue analizar la evolución de la presión alta en las últimas tres temporadas de la Primera División de Fútbol Española, en función de la clasificación ocupada y la localización del partido. La muestra del estudio incluyó 1,140 partidos disputados en las temporadas 2019-2020, 2020-2021 y 2021-2022. Se recopilaron datos de balones recuperados y balones recuperados en campo rival mediante el sistema Instat. A partir de estos datos, se creó una nueva variable denominada "Porcentaje de Presión", con el objetivo de interpretar las diferentes intenciones tácticas de los diversos equipos. Se encontraron diferencias significativas (p<.05) en el porcentaje de presión entre la primera y la tercera temporada y en el porcentaje de presión según la localización del partido, mostrando el equipo local un porcentaje mayor respecto al equipo visitante. Estos hallazgos proporcionan una mayor comprensión sobre las tendencias defensivas del fútbol actual.

Abstract. Knowledge of the game indicators that manifest during competition enables coaches to design training plans adapted to competitive demands. The aim of this study was to analyse the evolution of high pressure in the last three seasons of the Spanish First Division Football, based on the occupied ranking and the location of the match. The study sample included 1,140 matches played in the 2019-2020, 2020-2021, and 2021-2022 seasons. Data on recovered balls and balls recovered in the opponent's field were collected using the Instat system. Based on this data, a new variable called "Pressure Percentage" was created, with the aim of interpreting the different tactical intentions of the various teams. Significant differences (p<.05) were found in the pressure percentage between the first and third seasons and in the pressure percentage according to the match location, with the home team showing a higher percentage compared to the visiting team. These findings provide a greater understanding of current football defensive trends.

This research aims to improve the physical condition and interest of elementary school students in pencak silat sports in terms of kinesthetic intelligence. This research applied the action research method. Data collection techniques employed tests, measurements, and questionnaires. The research instruments were as follows: a physical condition test, a kinesthetic intelligence test using Natural Messy Play, and an interest test using a questionnaire. Data analysis used quantitative descriptive and qualitative descriptive. Quantitative data analysis employed quantitative descriptive statistics, namely comparing the results obtained from the Pre-Cycle, First Cycle, and Second Cycle. Qualitative data was used by analyzing data from observations during research. The results of the research showed that there was an increase in the physical condition and interest of elementary school students in pencak silat sports in terms of kinesthetic intelligence. In detail, the research results are as follows: 1) In the pre-cycle, it was 23.1%, cycle I increased to 38.5% and cycle II increased to 84.6%, 2) kinesthetic intelligence had a significant influence on the physical condition of school students elementary school, and 4) kinesthetic intelligence does not have a significant influence on elementary school students' interest in pencak silat sports.

The ability to have self-efficacy is an essential aspect for every individual. Self-efficacy skills that develop from an early age positively impact other factors, such as good social-emotional, cognitive, affective, motor skills, and academic. However, in real life, children's self-efficacy abilities still need to be developed because teachers still need to have the ability to choose suitable games to build them. This study looks at the effectiveness of the Warrior Kids' game in developing self-efficacy skills in children aged 5-6 years. This study used an experimental method with a one-group design, which compared the pre-test and post-test values; the sample used was 15 people, and the effectiveness, which is analyzed with Wilcoxon's formula, shows if the results of the study get a sig value of less than .05, the results obtained are .001, so it can be concluded that the efficacy of using warrior kids' games High means the efficacy of this game is in the high category, nature develops the self-efficacy abilities of early childhood. This is because the warrior kids' game can motivate children to conquer the game with exciting and fun obstacles, and each obstacle has been designed by prioritizing children's safety in playing so that children dare to try and participate in activities until they are finished properly.

Published: May 2024

El objetivo de este estudio fue analizar cómo influye en los parámetros técnicos y físicos la forma de reiniciar el juego en diferentes formatos de juegos reducidos en jugadores de fútbol masculino (n=20) de categoría cadete (15.3 ± 0.5 años) pertenecientes a la academia de un club profesional de la primera división de fútbol español 2022-2023. Se diseñaron dos juegos reducidos (2x2+2c y 4x4+2c) donde se utilizaba el constreñimiento de reinicio del juego por parte del entrenador y de saque de banda por parte de jugador. Se analizaron las variables físicas externas de distancia total, distancia a diferentes velocidades (7-13 km·h-1;13-18 km·h-1;18-21 km·h-1;21-24 km·h-1), velocidad máxima (<24km·h-1), medias (entre 2 y 3 m. s-2), altas aceleraciones/deceleraciones (> 3 m. s-2) y RPE y, las variables técnicas del pase y el control. Los resultados mostraron diferencias significativas en las variables físicas de baja intensidad y en las acciones técnicas de pase, cuando inicia la acción por el suelo, en el control cuando el balón no va por el suelo y se contacta con otras partes del cuerpo. Estos datos permiten, a través de este constreñimiento, generar una mayor variabilidad técnica a las tareas para que los entrenadores puedan generar escenarios de aprendizaje más próximos al juego.

Abstract. The aim of this study was to analyse the influence on technical and physical parameters of the way of restarting the game in different formats of small sided games in male football players (n=20) of cadet category (15.3 ± 0.5 years) belonging to the academy of a professional club of the first division of Spanish football 2022-2023. Two small sided games (2x2+2c and 4x4+2c) were designed using the coach's restart constraint and the player's throw-in constraint. The external physical variables of total distance, distance at different speeds (7-13 km-h-1;13-18 km-h-1;18-21 km-h-1;21-24 km-h-1), maximum speed (<24km-h-1), average (between 2 and 3 m. s-2), high accelerations/decelerations (> 3 m. s-2) and RPE and, the technical variables of passing and control were analysed. The results showed significant differences in the low intensity physical variables and in the technical actions of passing, when initiating the action on the ground, in control when the ball does not go on the ground and contact is made with other parts of the body. These data allow, through this constraint, to generate a greater technical variability to the tasks so that coaches can generate learning scenarios closer to the game.
