Published: February 2025

Introduction:

Fungal pyelonephritis is an infection of the renal parenchyma caused by fungal organisms, notably the Candida genus. In people with diabetes, immunocompromised, and critical care patients, it is responsible for most nosocomial infections with a high case fatality rate (40%–60%). In recent times, there has been a steady rise in fungal pyelonephritis cases, particularly with resistance to conventional antifungal agents such as fluconazole. This is primarily due to indiscriminate underdosing and improper inhospital management of these cases.

Materials and Methods:

An observational study of 25 patients of fungal pyelonephritis was conducted in the Nephrology Outpatient Department and ward at the Jawaharlal Nehru Medical College, Aligarh, Uttar Pradesh, India, from January 2023 to June 2023. The demographic characteristics, clinical, laboratory, microbiological, and radiological findings, therapeutic modalities, and patient outcomes were reviewed.

Results:

The mean age of the population was 52 ± 2.4 years. The study population comprised 32% males and 68% females. The majority of them (60%) had diabetes, only 20% of patients presented with the typical urinary tract infection symptoms, while 80% presented with nonspecific symptoms. All patients had the typical findings suggesting pyelonephritis on contrast-enhanced computed tomography (CECT). In comparison, 60% of patients had the typical findings suggestive of pyelonephritis on ultrasound abdomen. The distribution of the cases was as follows: 56% Candida albicans, 24% Candida glabrata, 12% Candida tropicalis, and 8% Candida krusei. Of the 25 patients, 60% improved, 20% expired, and 20% complicated into chronic kidney disease.

Conclusion:

Fungal pyelonephritis is a severe disease with marked renal and multi-systemic complications. However, timely management and optimal treatment can prevent serious consequences. Ultrasonography is effective for early detection, but CECT scan is needed to confirm and avoid misdiagnosis.

Introduction:

Kidney transplant recipients are at increased risk of severe outcomes from coronavirus disease 2019. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination has been shown to reduce hospitalisation and mortality rates in kidney transplant recipients, but vaccine hesitancy remains a concern. We surveyed kidney transplant recipients in a single centre to examine their perceptions and attitudes towards SARS-CoV-2 vaccination.

Methods:

A cross-sectional survey of kidney transplant recipients was conducted between June 2021 and August 2021. Questionnaire responses collected included demographic data, intention to receive SARS-CoV-2 vaccine and factors related to vaccine acceptance or hesitance. Predictors and reasons for vaccine acceptance were analysed.

Results:

In the sampled cohort of 313 respondents, the vaccine acceptance rate was 75%; 61% of the respondents were aged 51–70 years, and 31% had transplant vintages of 10–20 years. In a multivariable model, transplant physicians’ recommendation (odds ratio [OR] 4.1, 95% confidence interval [CI] 2.4–7.1, P < 0.001), male gender (OR 2.3, 95% CI 1.3–4.0, P = 0.003) and transplant vintage of <10 years (OR 2.0, 95% CI 1.2–3.5, P = 0.01) were predictors of vaccine acceptance. Recipients’ perceptions that SARS-CoV-2 vaccination confers protection and their trust in the government and health authorities on vaccine efficacy and safety were reasons for vaccine acceptance, while concerns about the effects of vaccination on allograft function and the safety and efficacy of vaccines were reasons for vaccine hesitancy. Assurance from transplant physicians played an important role in increasing vaccine acceptance.

Conclusion:

A high level of knowledge and trust in the doctor–patient relationship remain critical for kidney transplant recipients to improve vaccine acceptance. Continued efforts are required to address concerns about vaccine efficacy and safety in this population.

Published: February 2025

Les espèces plasmodiales responsables du paludisme circulent en Guinée forestière et constituent un problème de santé publique. Notre  étude visait à identifier les espèces plasmodiales circulant dans la région afin de freiner leur propagation. Des échantillons de sang  prélevés ont été examinés au laboratoire de CIRIT-Guinée. La technique de LAMP classique (L'amplification isothermique à  médiation par boucle) a été utilisée pour la détection des espèces plasmodiales. L'étude a été réalisée pendant six mois allant d’avril à  septembre 2022. Notre résultat a montré que, quatre espèces plasmodiales circulant dans la région ont été identifiées dont le    Plasmodium falciparum (78,93%), le Plasmodium malariae (11,43%), le Plasmodium ovale (7,14%) et le Plasmodium vivax (2,5%). Le   Plasmodium falciparum était le plus représenté. Le Plasmodium falciparum a été plus fréquent chez  les moins de 18 ans et chez les  femmes avec respectivement 97,71% et 88,24% de positivité. Les patients de 18 à 35 ans et les hommes étaient plus touchés par le  Plasmodium malariae, ovale et vivax. Notre résultat suggère la nécessité de dépistage, de contrôle et de suivi des mouvements de  population (voyageurs), de suivi des malades traités, de sensibilisation des communautés sur les mesures préventives.

Published: February 2025

Les insecticides de synthèse comme les organochlorés, les carbamates, les organophosphorés, les pyréthrinoïdes et de façon générale  les larvicides de synthèse, utilisés contre les moustiques ou leurs larves, dans le cadre de la lutte contre les vecteurs du paludisme, ont  des effets néfastes sur l’environnement et la santé humaine. En plus, de nombreux cas de résistance ont été constatés aussi bien chez les  moustiques que chez leurs larves. Ainsi, la recherche de nouvelles molécules d´origine végétale ayant des propriétés insecticides, insectifuges ou larvicides et leur utilisation pourrait être une méthode alternative à l’emploi des molécules de synthèse. Le présent travail  avait pour objectif principal l’étude des propriétés larvicides des composés isolés de l’extrait méthanolique des racines de  Xeromphis nilotica sur des larves des anophèles. La décoction était la technique d’extraction utilisée suivie d’extraction liquide-liquide. La  chromatographie sur colonne était utilisée dans la purification des fractions chloroformique et butanolique. Les analyses RMN et GC- MS des composés purs isolés étaient réalisées à l’aide du spectromètre Bruker et Shimadzu respectivement. L’activité larvicide était évaluée selon le protocol de l’OMS 1985. Trois composés ont été isolés et caractérisés à savoir la scopoletine (7- hydroxy-6-méthoxy  coumarine) composé A, et ses deux dérivés glycosylés composés B et C. Les données spectroscopiques relatives à ces structures viennent  enrichir la littérature. Les composés A (scopoletine) et B(monoglycoside) ont montré une importante activité larvicide vis-à-vis  des larves des anophèles. Ces composés pourraient justifier l’utilisation traditionnelle de cette plante comme insectifuge vis-à-vis des  moustiques.

Published: February 2025

In the Departments of Balleyara and Filingué in Niger, the development of irrigated agriculture is a key factor in improving food security.  Irrigation is considered as the best way to increase agricultural production and reduce its vulnerability to climate variability. The alluvial  aquifer of the dallol Bosso, easily mobilized because of its shallow depth, is heavily used for this purpose. However, this groundwater  resource is subjected to the effects of anthropogenic actions and climate change. The aims of this study, was to improve knowledge of  the aquifer system and the dynamics of the alluvial aquifer in the context of climate change. The methodology adopted was based on the  analysis of hydro-climatic and hydrodynamic parameters and their processing using various softwares. The results obtained showed a  decrease in precipitation from south to north part in the area, with interannual averages of 440.3 mm in Balleyara and 408.73 mm in  Filingué. The water balance estimated for the year 1952 showed an infiltration rate in the water table of 20.29% for an easily usable  reserve (RFU) of 100 mm and 23.79% for an RFU of 50 mm and the annual recharge of the water table for the year 2018 is estimated at  1.43108 m3 . The dynamics of land use between 1972 and 2014 showed a deterioration of vegetation in favor of bare surfaces. The alluvial  aquifer is mainly made up of sand of alluvial and aeolian origin, with thicknesses varying between 5 m and 27 m. The piezometry  shows a main flow direction from south to north, at the alluvial water table scale. These results showed that the alluvial aquifer is  favorable for irrigation.

Le changement climatique est considéré comme le plus grand danger et représente l’un des défis le plus important du siècle.  L’augmentation des températures, des précipitations, la fréquence des inondations et la propagation des maladies constituent les  éléments les plus ressentis. Ce constat est vérifié dans le cas du paludisme dont la transmission est étroitement liée aux conditions  climatiques. Les inondations entrainent la persistance des gîtes larvaires au-delà des périodes habituelles, créés des conditions  favorables à la survie des moustiques et modifie la répartition géographique par l’introduction et où le maintien permanent de certaines espèces vectrices, d’où la persistance de la transmission des maladies. Une étude prospective a été réalisée à N’Djaména dans le Sahel  Tchadien dans quatre quartiers dont deux inondés et deux non inondés. Les anophèles étaient capturés dans 10 chambres par jour  pendant trois jours consécutifs par quartier et par mois de décembre 2022 à mars 2023 puis morphologiquement identifiés et soumis au  test ELISA-CSP et PCR-Espèces. Les données météorologiques (précipitation et température) et épidémiologiques du paludisme des cinq  dernières années ont été analysées selon Liboschik. Les résultats de l’enquête ont montré que plus d’anophèles ont été capturés dans les quartiers inondés (79%) (p=0,0001). Anopheles coluzzii représentait 86% des espèces et était le principal vecteur (ICSP = 1,20%) suivi  de Anopheles arabiensis. A chaque inondation, le nombre de cas de paludisme augmente par rapport aux années ordinaires et la durée  de la transmission est allongée de 4 à 9 mois puisque les anophèles persistent et poursuivent la transmission en saison sèche, grâce aux  résidus des eaux d’inondations

This study examines the impact of polyethylene and polypropylene microplastics on the growth and pigment production of Scenedesmus sp. at three different concentrations (50, 100, and 150 mg L-1). The findings demonstrate that microplastic exposure negatively impacts microalgae growth and photosynthetic pigments, irrespective of polymer type, size, and concentration. The findings indicate that the reduction in total chlorophyll percentage and the suppression of microalgal development were more pronounced for particles smaller than 500 μm and at a concentration of 150 mg L-1. The percentage reduction in carotenoid levels remained consistent at 50 and 100 mg L-1 but decreased considerably at 150 mg L-1. In addition, phthalate release from the microplastics was studied for a mixture of polypropylene and polyethylene microplastics. Several phthalates were detected in the samples namely diethyl phthalate (4.43 ng mL-1), dibutyl phthalate (389.38 ng mL-1), benzyl butyl phthalate (0.81 ng mL-1), and diisobutyl phthalate (3.92 ng mL-1), each of which presents ecological hazards. We recommend further studies to investigate the long-term environmental impacts of these interactions.

Rapid technological developments have brought significant changes to everyday life, especially in the household environment. Electronic devices such as televisions, computers, refrigerators, washing machines, microwaves and air conditioners are now basic necessities in many households. Using these tools not only makes daily work easier, but also improves comfort and quality of life. This research aims to analyze the influence of the use of electronic devices in the household on electrical energy consumption and occupant behavior patterns. Electronic devices such as televisions, washing machines, air conditioners, refrigerators and other appliances are increasingly becoming an important part of everyday life, but inefficient use can cause a significant increase in energy consumption. This research uses a survey method of 10 or more households in a certain area to determine the frequency and duration of use of various electronic devices, as well as the level of awareness of respondents regarding energy consumption. The research results show that the most widely used electronic devices are televisions and air conditioners, with the largest contribution to electricity consumption coming from air conditioning (AC). In addition, it was found that household residents’ awareness of energy consumption is still low, even though there is interest in using energy-saving equipment. This research recommends further education regarding the efficient use of electronic devices and the importance of choosing devices that are labeled energy efficient to reduce household electricity loads. It is hoped that the results of this research can become the basis for formulating policies related to energy efficiency in the household sector.

Este artículo examina la importancia de incorporar las matemáticas financieras aplicadas en el plan de estudios de la educación secundaria, con la finalidad de aumentar la comprensión financiera de los alumnos y capacitarlos para realizar elecciones económicas fundamentadas en su etapa de adultos. A través de un análisis sistemático de investigaciones recientes, se analizan las ventajas que brinda la educación financiera al momento de fomentar habilidades tales como, la gestión de presupuestos, el ahorro, la inversión y la prevención del endeudamiento excesivo. Los hallazgos indican que los programas de educación financiera en las unidades educativas influyen positivamente en el entendimiento y las actitudes de los estudiantes respecto a las finanzas personales, aunque su eficacia varía según el entorno socioeconómico y cultural. Se destacan técnicas innovadoras, como la implementación de gamificación, proyectos fundamentados en problemas reales y herramientas digitales, que han probado ser eficaces para atraer la atención de los estudiantes y promover un aprendizaje relevante. Sin embargo, también existen retos, tales como la insuficiente formación de los profesores, la carencia de recursos pedagógicos apropiados y las desigualdades en el acceso a estos programas entre zonas urbanas y rurales. Se propone un marco teórico para la aplicación de la educación financiera en las unidades educativas, fundamentado en óptimas prácticas internacionales y ajustado a las demandas locales. Se concluye que la incorporación de las matemáticas financieras en la educación secundaria no solo favorece a las personas, sino que también impulsa el crecimiento económico y social de las comunidades, fomentando la inclusión financiera y disminuyendo las desigualdades económicas.
Juridical Analysis of the Appointment of Acting Officials in the Simultaneous Regional Elections in 2024 and its Implications for the Principles of Democracy in Indonesia

Published: February 2025

This study analyzes juridically the appointment of Acting Regional Heads in regional head elections (Pilkada) held simultaneously in 2024 and its implications for the principles of democracy in Indonesia. In the context of simultaneous regional elections, the vacancy of the position of regional head caused by the term of office that ends before the implementation of the elections is filled by the Acting Regional Head based on the provisions of Article 201 paragraph (9), (10), and (11) of Law Number 10 of 2016 governing Regional Head Elections. Acting Heads are appointed from among officials with Middle high-leadership positions in the Governor, and Primary high-leadership in the Regent or Mayor. This research uses a normative juridical method with a doctrinal approach, namely analyzing relevant legislation, jurisprudence, and the views of legal experts. The analysis shows that the appointment of Acting Regional Head is a strategic policy needed to maintain the continuity of regional government. However, the appointment mechanism that is fully determined by the central government without community involvement has various implications for democratic principles, such as reduced public participation, reduced accountability of the process of filling positions, and the absence of direct accountability to the people. The implications of the results of the analysis and studies in this research can be input and consideration for policy makers to improve the legal framework governing the appointment of Acting heads, so as to strengthen democratic principles and maintain political and government stability at the provincial, district or city level.

This study aims to explore the influence of metacognitive awareness and reading strategy awareness on the reading comprehension skills of senior high school students. A quantitative approach with a correlational method was used to explain the magnitude of the influence of the independent variables (metacognitive awareness and reading strategy awareness) and the dependent variable (reading comprehension skills). The students were 154 from six State Senior High Schools in Gunungsitoli City, North Sumatra. A questionnaire was used to obtain metacognitive and reading strategy awareness data. Meanwhile, data on reading comprehension skills were obtained using a test instrument. The data were analyzed using inferential statistics, namely multiple linear regression based on SPSS for Windows version 26. The research findings show (1) metacognitive awareness does not have a positive and significant effect on students' reading comprehension skills, (2) reading strategy awareness contributes positively and significantly to students' reading comprehension skills, and (3) metacognitive awareness and reading strategy awareness simultaneously contribute positively and significantly to students' reading comprehension skills. Based on these findings, reading comprehension ability can be explained by the variables of metacognitive awareness and reading strategy awareness by 24.70%. At the same time, the remaining 75.30% is explained by other variables. The findings of this study help learn reading comprehension in high schools. In other words, teachers must foster awareness of metacognitive and reading strategies among students. Further research can be conducted using other research designs and methods.

Introducción: La alfabetización motriz favorece la participación y mantenimiento de un nivel adecuado de actividad física durante el ciclo vital, reduce comportamiento sedentario, mejora marcadores de salud y calidad de vida en niñas, niños y adolescentes (NNA). Por tanto, se requieren instrumentos válidos y confiables para determinar la alfabetización motriz en NNA.
Objetivo: Examinar la validez y confiabilidad del cuestionario “Chilean Perceived Physical Literacy Instrument” (Ch-PPLI) en NNA chilenos de 10 a 18 años.
Metodología: Se desarrolló un proceso de adaptación cultural y validación de contenido con tres expertos bajo metodología Delphi, coeficiente de validación de contenido, y validación de constructo por análisis factorial exploratorio (AFE), con participantes de sexo femenino (n=134; 13,8±2,05 años) y masculino (n=146; 14,4±2,17 años). 
Resultados: La validación de expertos presentó coeficientes de validación de contenido entre 0,81 a 0,94 (i.e. “buenos” a “excelentes”). Las medidas de ajuste del modelo presentaron valores “satisfactorios” (Error de aproximación cuadrático medio [RMSEA=0,07; p<0,001]). El AFE agrupó ítems en un solo factor, presentando valores de confiabilidad “alta” (α=0,822 y ω=0,829). En ítems 1 a 5, y total del Ch-PPLI, los niños presentaron valores mayores versus niñas (todos p<0,05). En ítems 2 a 5, 7, 9 y total del Ch-PPLI, la población activa (cuestionario de niveles de actividad física >5 puntos) presentó valores mayores versus población inactiva físicamente (todos p<0,05).
Conclusiones: El Ch-PPLI mostró validez y confiabilidad en NNA chilenos de 10 a 18 años. El Ch-PPLI identificó diferencias de alfabetización motriz entre hombres y mujeres, y entre individuos activos e inactivos físicamente.

Published: February 2025

Objetivo: Comparar la respuesta fisiológica del sistema cardiorrespiratorio durante dos sesiones de ejercicio; una sincronizada con música, y la otra dirigida por un instructor mientras se escucha música de preferencia personal.
Metodología: Se llevó a cabo un estudio cuasiexperimental cruzado con 13 individuos (7 hombres, edad media 23,7 años). Los participantes realizaron dos sesiones de ejercicio: una con sincronización musical y otra no sincronizada, pero escuchando la música de preferencia personal, con un intervalo de 72 horas entre las sesiones. Se evaluaron la frecuencia cardíaca (FC), la percepción de esfuerzo (PE), la carga interna de entrenamiento (CIE) y la variabilidad del ritmo cardíaco (VRC) durante las sesiones.
Resultados: Durante la sesión sincronizada, se observaron valores significativamente más bajos de FC media y FC pico (Δ-5,5% y Δ-5,2%, respectivamente) y una menor PE pico (Δ-9,9%) en comparación con la sesión no sincronizada. La CIE también fue menor (Δ-10%) en el ejercicio sincronizado. No se encontraron diferencias significativas en la VRC entre las sesiones. Las variaciones de la FC y la PE fueron determinadas por los cambios temporales durante las sesiones. Solo los cambios en la FC fueron determinados por la sincronización musical de los ejercicios.
Conclusiones: En la muestra estudiada, el ejercicio musicalmente sincronizado resultó en una menor intensidad cardiovascular percibida, sin variaciones sobre la regulación autonómica.

For the adolescents with progressive Idiopathic Scoliosis and
a Cobb angle beyond 25º, bracing is still the standard of care.
However, many curves will continue to deteriorate due to
refractory progression, refusal to accept this type of treatment or
patient noncompliance. Surgery is required when nonoperative
management fails, in order to prevent curve progression, correct
the deformity and to minimize morbidity but at the costs of fusing
a segment of the deformed spine and loosing spinal motion. For

Published: February 2025

This study aims to analyze the perceptions of Islamic Religious Education teachers regarding the use of WhatsApp as an online learning platform. Using a mixed parallel convergent research method, this research collects quantitative data through surveys, while qualitative data is obtained through in-depth interviews, observation, and documentation studies. This study shows that students in teacher certification programs in Indonesia are heavy users of WhatsApp, as evidenced by 97% of quantitative research respondents spending more than 4 hours per day for academic purposes. With an average standard deviation value of 0.816, this study confirms that students' perceptions of WhatsApp positively impact academic achievement. This is reasonable because they see WhatsApp as having flexibility not limited by place and time; features that are easy to use, integrated with lecture support software; and a fairly strong data security system. In implementing the certification program, WhatsApp's advantages are used to support the success of online classes, such as group discussions, sharing educational knowledge, sharing references, and finding academic agendas. This study also shows that WhatsApp can encourage of Islamic Religious Education teachers to have collaborative skills in teams. However, WhatsApp is still not maximized due to the absence of features for conducting evaluations, a poor learning management system, and the internet in Indonesia, which is not evenly distributed. These findings can be used as a basis for the government to improve the quality of online learning through WhatsApp. Because of its important role in the teacher certification program, we expected that Islamic religious education teachers can use the features in WhatsApp to optimize their use in the academic world

Authors: Wen Han Seow , Chia Yean Lim , Sau Loong Ang
Published: February 2025

In the fast-paced world of software engineering, Continuous Integration/Continuous Delivery (CI/CD) pipelines are essential to deliver software builds continuously. However, the varying time taken for software builds to complete on these pipelines can challenge scheduling software delivery and impact productivity. To the best of researchers' knowledge, machine learning techniques have never been used to predict software build time in the CI/CD pipeline. This research attempted to apply data science and machine learning techniques, including linear regression (LR), support vector regressor (SVR), random forest regressor (RFR), and XGBoost regressor, to predict software build completion time to address this research gap. Past build events were used as a dataset to train and identify the best-performing model by evaluating the time a software build takes to complete. Different factors contributing to software build time on the CI/CD pipeline were also analyzed to identify opportunities for improvement. This research found that the random forest (RF) model achieved the best and outstanding performance of 14.306 in mean squared error (MSE). This model could be deployed to provide completion time estimates for software builds, enabling better code delivery scheduling. This research also suggested opportunities for improvement in the CI/CD pipeline by discovering major factors causing high build time in the CI/CD pipeline that engineers could rectify to reduce software build time in the CI/CD pipeline.
